+
+- Issue #16046: Fix loading sourceless legacy .pyo files.
+
+- Issue #16060: Fix refcounting bug when __trunc__ returns an object
+  whose __int__ gives a non-integer.  Patch by Serhiy Storchaka.
+
+Extension Modules
+-----------------
+
+- Issue #16012: Fix a regression in pyexpat. The parser's UseForeignDTD()
+  method doesn't require an argument again.
+
+
+What's New in Python 3.3.0 Release Candidate 3?
+===============================================
+
+*Release date: 23-Sep-2012*
+
+Core and Builtins
+-----------------
+
+- Issue #15900: Fix reference leak in PyUnicode_TranslateCharmap().
+
+- Issue #15926: Fix crash after multiple reinitializations of the interpreter.
+
+- Issue #15895: Fix FILE pointer leak in one error branch of
+  PyRun_SimpleFileExFlags() when filename points to a pyc/pyo file, closeit
+  is false an and set_main_loader() fails.
+
+- Fixes for a few crash and memory leak regressions found by Coverity.
+
+Library
+-------
+
+- Issue #15882: Change _decimal to accept any coefficient tuple when
+  constructing infinities. This is done for backwards compatibility
+  with decimal.py: Infinity coefficients are undefined in _decimal
+  (in accordance with the specification).
+
+- Issue #15925: Fix a regression in email.util where the parsedate() and
+  parsedate_tz() functions did not return None anymore when the argument could
+  not be parsed.
+
+Extension Modules
+-----------------
+
+- Issue #15973: Fix a segmentation fault when comparing datetime timezone
+  objects.

+  dump_traceback_later() and cancel_dump_tracebacks_later() to
+  cancel_dump_traceback_later().
+
+- _decimal module: use only C 89 style comments.
+
+
+What's New in Python 3.3.0 Release Candidate 2?
+===============================================
+
+*Release date: 09-Sep-2012*
+
+Core and Builtins
+-----------------
+
+- Issue #13992: The trashcan mechanism is now thread-safe.  This eliminates
+  sporadic crashes in multi-thread programs when several long deallocator
+  chains ran concurrently and involved subclasses of built-in container
+  types.
+
+- Issue #15784: Modify OSError.__str__() to better distinguish between
+  errno error numbers and Windows error numbers.
+
+- Issue #15781: Fix two small race conditions in import's module locking.
+
+Library
+-------
+
+- Issue #15847: Fix a regression in argparse, which did not accept tuples
+  as argument lists anymore.
+
+- Issue #15828: Restore support for C extensions in imp.load_module().
+
+- Issue #15340: Fix importing the random module when /dev/urandom cannot
+  be opened.  This was a regression caused by the hash randomization patch.
+
+- Issue #10650: Deprecate the watchexp parameter of the Decimal.quantize()
+  method.
+
+- Issue #15785: Modify window.get_wch() API of the curses module: return
+  a character for most keys, and an integer for special keys, instead of
+  always returning an integer. So it is now possible to distinguish special
+  keys like keypad keys.
+
+- Issue #14223: Fix window.addch() of the curses module for special characters
+  like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now
+  calling the C function waddch()/mvwaddch() (as it was done in Python 3.2),
+  instead of wadd_wch()/mvwadd_wch(). The Python function addch(str) is still
+  calling the C function wadd_wch()/mvwadd_wch() if the Python curses is linked
+  to libncursesw.
+
+Build
+-----
+
+- Issue #15822: Really ensure 2to3 grammar pickles are properly installed
+  (replaces fixes for Issue #15645).
+
+Documentation
+-------------
+
+- Issue #15814: The memoryview enhancements in 3.3.0 accidentally permitted
+  the hashing of multi-dimensional memorviews and memoryviews with multi-byte
+  item formats. The intended restrictions have now been documented - they
+  will be correctly enforced in 3.3.1

+  even when msg isn't a str.

+
+- Create a 'Concurrent Execution' section in the docs, and split up the
+  'Optional Operating System Services' section to use a more user-centric
+  classification scheme (splitting them across the new CE section, IPC and

+    * Try to avoid building Python or extension modules with problematic
+      llvm-gcc compiler.
+    * Since Xcode 4 removes ppc support, extension module builds now
+      check for ppc compiler support and automatically remove ppc and
+      ppc64 archs when not available.
+    * Since Xcode 4 no longer install SDKs in default locations,
+      extension module builds now revert to using installed headers
+      and libs if the SDK used to build the interpreter is not
+      available.
+    * Update ./configure to use better defaults for universal builds;
+      in particular, --enable-universalsdk=yes uses the Xcode default
+      SDK and --with-universal-archs now defaults to "intel" if ppc
+      not available.
+
+- Issue #14225: Fix Unicode support for curses (#12567) on OS X

+
+Core and Builtins
+-----------------
+
+- Issue #14172: Fix reference leak when marshalling a buffer-like object
+  (other than a bytes object).
+
+- Issue #13521: dict.setdefault() now does only one lookup for the given key,
+  making it "atomic" for many purposes.  Patch by Filip Gruszczyński.
+
+- PEP 409, Issue #6210: "raise X from None" is now supported as a means of
+  suppressing the display of the chained exception context. The chained
+  context still remains available as the __context__ attribute.
+
+- Issue #10181: New memoryview implementation fixes multiple ownership
+  and lifetime issues of dynamically allocated Py_buffer members (#9990)
+  as well as crashes (#8305, #7433). Many new features have been added

+
+- Fix the builtin module initialization code to store the init function for
+  future reinitialization.
+
+- Issue #8052: The posix subprocess module would take a long time closing
+  all possible file descriptors in the child process rather than just open
+  file descriptors.  It now closes only the open fds if possible for the
+  default close_fds=True behavior.
+
+- Issue #13629: Renumber the tokens in token.h so that they match the indexes
+  into _PyParser_TokenNames.
+
+- Issue #13752: Add a casefold() method to str.

+  used to ensure flushing the output stream.
+
+- Issue #13645: pyc files now contain the size of the corresponding source
+  code, to avoid timestamp collisions (especially on filesystems with a low
+  timestamp resolution) when checking for freshness of the bytecode.
+
+- PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to
+  subgenerators (initial patch by Greg Ewing, integration into 3.3 by
+  Renaud Blanch, Ryan Kelly, Zbigniew Jędrzejewski-Szmek and Nick Coghlan)

+  in order to allow unpickling under Python 2.  Patch by Irmen de Jong.
+
+- Issue #7111: Python can now be run without a stdin, stdout or stderr
+  stream.  It was already the case with Python 2.  However, the corresponding
+  sys module entries are now set to None (instead of an unusable file object).
+
+- Issue #11849: Ensure that free()d memory arenas are really released
+  on POSIX systems supporting anonymous memory mappings.  Patch by
+  Charles-François Natali.
+
+- Issue #13452: PyUnicode_EncodeDecimal() doesn't support error handlers
+  different than "strict" anymore. The caller was unable to compute the
+  size of the output buffer: it depends on the error handler.
+
+- PEP 3155 / issue #13448: Qualified name for classes and functions.
+
+- Issue #13436: Fix a bogus error message when an AST object was passed
+  an invalid integer value.

+- Issue #10227: Add an allocation cache for a single slice object.  Patch by
+  Stefan Behnel.
+
+- Issue #13393: BufferedReader.read1() now asks the full requested size to

+
+- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
+
+- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
+  already accepts them).
+
+- Issue #13389: Full garbage collection passes now clear the freelists for
+  list and dict objects.  They already cleared other freelists in the
+  interpreter.
+
+- Issue #13327: Remove the need for an explicit None as the second argument
+  to os.utime, os.lutimes, os.futimes, os.futimens, os.futimesat, in
+  order to update to the current time. Also added keyword argument
+  handling to os.utimensat in order to remove the need for explicit None.
+
+- Issue #13350: Simplify some C code by replacing most usages of
+  PyUnicode_Format by PyUnicode_FromFormat.
+
+- Issue #13342: input() used to ignore sys.stdin's and sys.stdout's unicode
+  error handler in interactive mode (when calling into PyOS_Readline()).
+
+- Issue #9896: Add start, stop, and step attributes to range objects.
+
+- Issue #13343: Fix a SystemError when a lambda expression uses a global
+  variable in the default value of a keyword-only argument: ``lambda *,

+  FileIO.open().
+
+- Issue #10519: Avoid unnecessary recursive function calls in

+  Patch by Suman Saha.
+
+- Issue #13201: Define '==' and '!=' to compare range objects based on
+  the sequence of values they define (instead of comparing based on

+
+- Issue #10968: Remove indirection in threading.  The public names (Thread,
+  Condition, etc.) used to be factory functions returning instances of hidden

+
+- Issue #12016: Multibyte CJK decoders now resynchronize faster. They only

+
+- Issue #12459: time.sleep() now raises a ValueError if the sleep length is

+  disk space statistics.
+
+- Issue #12451: The XInclude default loader of xml.etree now decodes files from

+
+- Issue #12451: doctest.debug_script() doesn't create a temporary file

+
+- Issue #12451: pydoc.synopsis() now reads the encoding cookie if available,

+
+- Issue #12451: distutils now opens the setup script in binary mode to read the

+
+- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
+  check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
+  interpreter process.  This could cause failures in non-Distutils subprocesses
+  and was unreliable since tests or user programs could modify the interpreter
+  environment after Distutils set it.  Instead, have Distutils set the the
+  deployment target only in the environment of each build subprocess.  It is
+  still possible to globally override the default by setting
+  MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
+  greater or equal to the default value, the value with which the interpreter
+  was built.  Also, implement the same handling in packaging.

+
+- Issue #12624: It is now possible to fail after the first failure when
+  running in verbose mode (``-v`` or ``-W``), by using the ``--failfast``

+- Avoid failing in test_urllibnet.test_bad_address when some overzealous
+  DNS service (e.g. OpenDNS) resolves a non-existent domain name.  The test
+  is now skipped instead.

+
+- Issue #12407: Explicitly skip test_capi.EmbeddingTest under Windows.
+
+- Issue #12400: regrtest -W doesn't rerun the tests twice anymore, but captures

+  error twice anymore if there is only one error.
+
+- Issue #12141: Install copies of template C module file so that
+  test_build_ext of test_distutils and test_command_build_ext of
+  test_packaging are no longer silently skipped when

+
+- Issue #11223: Skip test_lock_acquire_interruption() and

+-----------------
+
+- Issue #10451: memoryview objects could allow to mutate a readable buffer.
+  Initial patch by Ross Lagerwall.
+
+Library
+-------
+
+- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
+  files in binary mode, using the email package's binary support to parse
+  arbitrary email messages.  StringIO and text file input is deprecated,
+  and string input fails early if non-ASCII characters are used, where
+  previously it would fail when the email was processed in a later step.
+
+- Issue #10845: Mitigate the incompatibility between the multiprocessing
+  module on Windows and the use of package, zipfile or directory execution
+  by special casing main modules that actually *are* called __main__.py.

+- Issue #11045: Protect logging call against None argument.
+
+- Issue #11052: Correct IDLE menu accelerators on Mac OS X for Save
+  commands.
+
+- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
+  preventing a confusing hung appearance on OS X with the windows
+  obscured.
+
+- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the
+  menu accelerators for Open Module, Go to Line, and New Indent Width.
+  The accelerators still work but no longer appear in the menu items.
+
+- Issue #10989: Fix a crash on SSLContext.load_verify_locations(None, True).
+
+- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3
+  conversion.
+
+- Issue #11019: Fixed BytesGenerator so that it correctly handles a Message
+  with a None body.
+
+- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
+  keyword-only argument.  The preceding positional argument was deprecated,
+  so it made no sense to add filter as a positional argument.
+
+- Issue #11004: Repaired edge case in deque.count().
+
+- Issue #10974: IDLE no longer crashes if its recent files list includes files
+  with non-ASCII characters in their path names.

+  return sets instead of one returning a tuple and the other a frozenset.
+
+- Issue #10987: Fix the recursion limit handling in the _pickle module.
+
+- Issue #10983: Fix several bugs making tunnel requests in http.client.
+
+- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode

+  a symbol named FSTAT.
+
+- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
+  encoding.  This is the preferred encoding of PEP 3333 and the base encoding
+  of HTTP 1.1.
+
+- To match the behaviour of HTTP server, the HTTP client library now also
+  encodes headers with iso-8859-1 (latin1) encoding.  It was already doing
+  that for incoming headers which makes this behaviour now consistent in
+  both incoming and outgoing direction.
+
+- Issue #9509: argparse now properly handles IOErrors raised by
+  argparse.FileType.
+
+- Issue #10961: The new pydoc server now better handles exceptions raised

+
+- Remove buffer API from stable ABI for now, see #10181.
+
+- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
+  doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int

+- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
+  and a non-zero offset, and an attempt to read past the end of file is made
+  (IndexError is raised instead).  Patch by Ross Lagerwall.
+
+- Issue #10154, #10090: change the normalization of UTF-8 to "UTF-8" instead
+  of "UTF8" in the locale module as the latter is not supported MacOSX and OpenBSD.
+
+- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
+  than the currently problematic Apple-supplied one, when running with the
+  64-/32-bit installer variant.
+
+- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
+  as unicode, and accept binary files. Add encoding and errors attributes to
+  cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
+  Linderman).
+
+- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl().
+
+- Issue #10899: No function type annotations in the standard library.  Removed
+  function type annotations from _pyio.py.

+  twice.
+
+- Issue #5871: email.header.Header.encode now raises an error if any
+  continuation line in the formatted value has no leading white space and looks
+  like a header.  Since Generator uses Header to format all headers, this check
+  is made for all headers in any serialized message at serialization time.  This
+  provides protection against header injection attacks.
+
+- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially
+  private by renaming it to ``_GeneratorContextManager``.
+
+- Issue #10042: Fixed the total_ordering decorator to handle cross-type
+  comparisons that could lead to infinite recursion.
+
+- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
+  non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
+  presentation, instead of replacing them with ?s.
+
+- email.header.Header was incorrectly encoding folding whitespace when
+  rfc2047-encoding header values with embedded newlines, leaving them without
+  folding whitespace.  It now uses the continuation_ws, as it does for
+  continuation lines that it creates itself.
+
+- Issue #1777412, #10827: Changed the rules for 2-digit years. The
+  time.asctime(), time.ctime() and time.strftime() functions will now format
+  any year when ``time.accept2dyear`` is False and will accept years >= 1000
+  otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
+  supported by the OS. With Visual Studio or on Solaris, the year is limited to
+  the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
+
+- Issue #7858: Raise an error properly when os.utime() fails under Windows
+  on an existing file.
+
+- Issue #3839: wsgiref should not override a Content-Length header set by
+  the application.  Initial patch by Clovis Fabricio.
+
+- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
+  compilation (if the input is a string).
+
+- Issue #7995: When calling accept() on a socket with a timeout, the returned
+  socket is now always blocking, regardless of the operating system.
+
+- Issue #10756: atexit normalizes the exception before displaying it. Patch by
+  Andreas Stührk.
+
+- Issue #10790: email.header.Header.append's charset logic now works correctly
+  for charsets whose output codec is different from its input codec.
+
+- Issue #10819: SocketIO.name property returns -1 when its closed, instead of
+  raising a ValueError, to fix repr().
+
+- Issue #8650: zlib.compress() and zlib.decompress() raise an OverflowError if
+  the input buffer length doesn't fit into an unsigned int (length bigger than
+  2^32-1 bytes).
+
+- Issue #6643: Reinitialize locks held within the threading module after fork to
+  avoid a potential rare deadlock or crash on some platforms.
+
+- Issue #10806, issue #9905: Fix subprocess pipes when some of the standard file
+  descriptors (0, 1, 2) are closed in the parent process.  Initial patch by Ross
+  Lagerwall.
+
+- `unittest.TestCase` can be instantiated without a method name; for simpler
+  exploration from the interactive interpreter.
+
+- Issue #10798: Reject supporting concurrent.futures if the system has too
+  few POSIX semaphores.
+
+- Issue #10807: Remove base64, bz2, hex, quopri, rot13, uu and zlib codecs from
+  the codec aliases. They are still accessible via codecs.lookup().
+
+- Issue #10801: In zipfile, support different encodings for the header and the
+  filenames.
+
+- Issue #6285: IDLE no longer crashes on missing help file; patch by Scott
+  David Daniels.
+
+- Fix collections.OrderedDict.setdefault() so that it works in subclasses that
+  define __missing__().
+
+- Issue #10786: unittest.TextTestRunner default stream no longer bound at import
+  time. `sys.stderr` now looked up at instantiation time.  Fix contributed by
+  Mark Roddy.
+
+- Issue #10753: Characters ';', '=' and ',' in the PATH_INFO environment variable
+  won't be quoted when the URI is constructed by the wsgiref.util's request_uri
+  method. According to RFC 3986, these characters can be a part of params in
+  PATH component of URI and need not be quoted.
+
+- Issue #10738: Fix webbrowser.Opera.raise_opts.
+
+- Issue #9824: SimpleCookie now encodes , and ; in values to cater to how
+  browsers actually parse cookies.
+
+- Issue #9333: os.symlink now available regardless of user privileges.  The
+  function now raises OSError on Windows >=6.0 when the user is unable to create
+  symbolic links. XP and 2003 still raise NotImplementedError.
+
+- Issue #10783: struct.pack() no longer implicitly encodes unicode to UTF-8.
+

+- Issue #10626: test_logging now preserves logger disabled states.
+
+- Issue #10774: test_logging now removes temp files created during tests.
+
+- Issue #5258/#10642: if site.py encounters a .pth file that generates an error,
+  it now prints the filename, line number, and traceback to stderr and skips
+  the rest of that individual file, instead of stopping processing entirely.
+
+- Issue #10763: subprocess.communicate() closes stdout and stderr if both are
+  pipes (bug specific to Windows).
+
+- Issue #1693546: fix email.message RFC 2231 parameter encoding to be in better
+  compliance (no "s around encoded values).
+
+- Improved the diff message in the unittest module's assertCountEqual().
+
+- Issue #1155362: email.utils.parsedate_tz now handles a missing space before
+  the '-' of a timezone field as well as before a '+'.

+
+C-API
+-----

+  PyObject_GetAttr, instead of replacing it with something less informative
+
+- Issue #10913: Deprecate misleading functions PyEval_AcquireLock() and
+  PyEval_ReleaseLock().  The thread-state aware APIs should be used instead.
+
+- Issue #10333: Remove ancient GC API, which has been deprecated since Python
+  2.2.
+
+Build
+-----
+
+- Issue #10843: Update third-party library versions used in OS X 32-bit

+  and RTREE enabled), and ncursesw 5.5 (wide-char support enabled).
+
+- Issue #10820: Fix OS X framework installs to support version-specific
+  scripts (#10679).

+  and DragonFly BSD.  Patch by Nicolas Joly.
+
+- Issue #10679: The "idle", "pydoc" and "2to3" scripts are now installed with
+  a version-specific suffix on "make altinstall".
+
+- Issue #10655: Fix the build on PowerPC on Linux with GCC when building with
+  timestamp profiling (--with-tsc): the preprocessor test for the PowerPC
+  support now looks for "__powerpc__" as well as "__ppc__": the latter seems to
+  only be present on OS X; the former is the correct one for Linux with GCC.
+
+- Issue #1099: Fix the build on MacOSX when building a framework with pydebug
+  using GCC 4.0.
+
+Tools/Demos
+-----------
+

+
+- `python -m test` can be used to run the test suite as well as `python -m
+  test.regrtest`.

+
+
+What's New in Python 3.2 Alpha 4?
+=================================
+
+*Release date: 13-Nov-2010*
+
+Core and Builtins
+-----------------
+
+- Issue #10372: Import the warnings module only after the IO library is
+  initialized, so as to avoid bootstrap issues with the '-W' option.
+
+- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
+  undocumented value PyBUF_SHADOW, and strangely-looking code in
+  PyMemoryView_GetContiguous.
+
+- Issue #6081: Add str.format_map(), similar to ``str.format(**mapping)``.
+
+- If FileIO.__init__ fails, close the file descriptor.
+
+- Issue #10221: dict.pop(k) now has a key error message that includes the
+  missing key (same message d[k] returns for missing keys).
+
+- Issue #5437: A preallocated MemoryError instance should not keep traceback
+  data (including local variables caught in the stack trace) alive infinitely.
+
+- Issue #10186: Fix the SyntaxError caret when the offset is equal to the length
+  of the offending line.
+
+- Issue #10089: Add support for arbitrary -X options on the command line.  They
+  can be retrieved through a new attribute ``sys._xoptions``.
+
+- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
+  the locale encoding.  If the LANG (and LC_ALL and LC_CTYPE) environment
+  variable is not set, the locale encoding is ISO-8859-1, whereas most programs
+  (including Python) expect UTF-8.  Python already uses UTF-8 for the filesystem
+  encoding and to encode command line arguments on this OS.
+
+- Issue #9713, #10114: Parser functions (e.g. PyParser_ASTFromFile) expect
+  filenames encoded to the filesystem encoding with the surrogateescape error
+  handler (to support undecodable bytes), instead of UTF-8 in strict mode.
+
+- Issue #9997: Don't let the name "top" have special significance in scope
+  resolution.
+
+- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
+  the default 512 when compiling on AIX.
+
+- Use locale encoding instead of UTF-8 to encode and decode filenames if
+  Py_FileSystemDefaultEncoding is not set.
+
+- Issue #10095: fp_setreadl() doesn't reopen the file, instead reuse the file
+  descriptor.
+
+- Issue #9418: Moved private string methods ``_formatter_parser`` and
+  ``_formatter_field_name_split`` into a new ``_string`` module.
+
+- Issue #9992: Remove PYTHONFSENCODING environment variable.
+
+Library
+-------
+
+- Issue #12943: python -m tokenize support has been added to tokenize.
+
+- Issue #10465: fix broken delegating of attributes by gzip._PaddedFile.
+
+- Issue #10356: Decimal.__hash__(-1) should return -2.
+
+- Issue #1553375: logging: Added stack_info kwarg to display stack information.
+
+- Issue #5111: IPv6 Host in the Header is wrapped inside [ ]. Patch by Chandru.
+
+- Fix Fraction.__hash__ so that Fraction.__hash__(-1) is -2.  (See also issue
+  #10356.)
+
+- Issue #4471: Add the IMAP.starttls() method to enable encryption on standard
+  IMAP4 connections.  Original patch by Lorenzo M. Catucci.
+
+- Issue #1466065: Add 'validate' option to base64.b64decode to raise an error if
+  there are non-base64 alphabet characters in the input.
+
+- Issue #10386: Add __all__ to token module; this simplifies importing in
+  tokenize module and prevents leaking of private names through ``import *``.
+
+- Issue #4471: Properly shutdown socket in IMAP.shutdown().  Patch by Lorenzo
+  M. Catucci.
+
+- Fix IMAP.login() to work properly.
+
+- Issue #9244: multiprocessing pool worker processes could terminate
+  unexpectedly if the return value of a task could not be pickled.  Only the
+  ``repr`` of such errors are now sent back, wrapped in an
+  ``MaybeEncodingError`` exception.
+
+- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
+  ``multiprocessing.Pool`` now accepts a ``error_callback`` argument.  This can
+  be a callback with the signature ``callback(exc)``, which will be called if
+  the target raises an exception.
+
+- Issue #10022: The dictionary returned by the ``getpeercert()`` method of SSL
+  sockets now has additional items such as ``issuer`` and ``notBefore``.
+
+- ``usenetrc`` is now false by default for NNTP objects.
+
+- Issue #1926: Add support for NNTP over SSL on port 563, as well as STARTTLS.
+  Patch by Andrew Vant.
+
+- Issue #10335: Add tokenize.open(), detect the file encoding using
+  tokenize.detect_encoding() and open it in read only mode.
+
+- Issue #10321: Add support for binary data to smtplib.SMTP.sendmail, and a new
+  method send_message to send an email.message.Message object.
+
+- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
+  handler to parse the Makefile file.  Avoid a UnicodeDecodeError if the source
+  code directory name contains a non-ASCII character and the locale encoding is
+  ASCII.
+
+- Issue #10329: The trace module writes reports using the input Python script
+  encoding, instead of the locale encoding.  Patch written by Alexander
+  Belopolsky.
+
+- Issue #10126: Fix distutils' test_build when Python was built with
+  --enable-shared.
+
+- Issue #9281: Prevent race condition with mkdir in distutils.  Patch by
+  Arfrever.
+
+- Issue #10229: Fix caching error in gettext.
+
+- Issue #10252: Close file objects in a timely manner in distutils code and
+  tests.  Patch by Brian Brazil, completed by Éric Araujo.
+
+- Issue #10180: Pickling file objects is now explicitly forbidden, since
+  unpickling them produced nonsensical results.
+
+- Issue #10311: The signal module now restores errno before returning from its
+  low-level signal handler.  Patch by Hallvard B Furuseth.
+
+- Issue #10282: Add a ``nntp_implementation`` attribute to NNTP objects.
+
+- Issue #10283: Add a ``group_pattern`` argument to NNTP.list().
+
+- Issue #10155: Add IISCGIHandler to wsgiref.handlers to support IIS CGI
+  environment better, and to correct unicode environment values for WSGI 1.0.1.
+
+- Issue #10281: nntplib now returns None for absent fields in the OVER/XOVER
+  response, instead of raising an exception.
+
+- wsgiref now implements and validates PEP 3333, rather than an experimental
+  extension of PEP 333.  (Note: earlier versions of Python 3.x may have
+  incorrectly validated some non-compliant applications as WSGI compliant; if
+  your app validates with Python <3.2b1+, but not on this version, it is likely
+  the case that your app was not compliant.)
+
+- Issue #10280: NNTP.nntp_version should reflect the highest version advertised
+  by the server.
+
+- Issue #10184: Touch directories only once when extracting a tarfile.
+
+- Issue #10199: New package, ``turtledemo`` now contains selected demo scripts
+  that were formerly found under Demo/turtle.
+
+- Issue #10265: Close file objects explicitly in sunau.  Patch by Brian Brazil.
+
+- Issue #10266: uu.decode didn't close in_file explicitly when it was given as a

+
+- Issue #10110: Queue objects didn't recognize full queues when the maxsize
+  parameter had been reduced.
+
+- Issue #10160: Speed up operator.attrgetter.  Patch by Christos Georgiou.
+
+- logging: Added style option to basicConfig() to allow %, {} or $-formatting.
+
+- Issue #5729: json.dumps() now supports using a string such as '\t' for
+  pretty-printing multilevel objects.
+
+- Issue #10253: FileIO leaks a file descriptor when trying to open a file for
+  append that isn't seekable.  Patch by Brian Brazil.
+
+- Support context manager protocol for file-like objects returned by mailbox
+  ``get_file()`` methods.
+
+- Issue #10246: uu.encode didn't close file objects explicitly when filenames
+  were given to it.  Patch by Brian Brazil.
+
+- Issue #10198: fix duplicate header written to wave files when writeframes() is
+  called without data.
+
+- Close file objects in modulefinder in a timely manner.
+
+- Close a io.TextIOWrapper object in email.parser in a timely manner.
+
+- Close a file object in distutils.sysconfig in a timely manner.
+
+- Close a file object in pkgutil in a timely manner.
+
+- Issue #10233: Close file objects in a timely manner in the tarfile module and
+  its test suite.
+
+- Issue #10093: ResourceWarnings are now issued when files and sockets are
+  deallocated without explicit closing.  These warnings are silenced by default,
+  except in pydebug mode.
+
+- tarfile.py: Add support for all missing variants of the GNU sparse extensions
+  and create files with holes when extracting sparse members.
+
+- Issue #10218: Return timeout status from ``Condition.wait`` in threading.
+
+- Issue #7351: Add ``zipfile.BadZipFile`` spelling of the exception name and
+  deprecate the old name ``zipfile.BadZipfile``.
+
+- Issue #5027: The standard ``xml`` namespace is now understood by
+  xml.sax.saxutils.XMLGenerator as being bound to
+  http://www.w3.org/XML/1998/namespace.  Patch by Troy J. Farrell.
+
+- Issue #5975: Add csv.unix_dialect class.
+
+- Issue #7761: telnetlib.interact failures on Windows fixed.
+
+- logging: Added style option to Formatter to allow %, {} or $-formatting.
+
+- Issue #5178: Added tempfile.TemporaryDirectory class that can be used as a
+  context manager.
+
+- Issue #1349106: Generator (and BytesGenerator) flatten method and Header
+  encode method now support a 'linesep' argument.
+
+- Issue #5639: Add a *server_hostname* argument to ``SSLContext.wrap_socket`` in
+  order to support the TLS SNI extension.  ``HTTPSConnection`` and ``urlopen()``
+  also use this argument, so that HTTPS virtual hosts are now supported.
+
+- Issue #10166: Avoid recursion in pstats Stats.add() for many stats items.
+
+- Issue #10163: Skip unreadable registry keys during mimetypes initialization.
+

+  root directory issue on posixpath.relpath().  (Ported working fixes from
+  ntpath.)
+
+- Issue #1343: xml.sax.saxutils.XMLGenerator now has an option
+  short_empty_elements to direct it to use self-closing tags when appropriate.
+
+- Issue #9807 (part 1): Expose the ABI flags in sys.abiflags.  Add --abiflags
+  switch to python-config for command line access.
+
+- Issue #6098: Don't claim DOM level 3 conformance in minidom.
+
+- Issue #5762: Fix AttributeError raised by ``xml.dom.minidom`` when an empty
+  XML namespace attribute is encountered.
+
+- Issue #2830: Add the ``html.escape()`` function, which quotes all problematic
+  characters by default.  Deprecate ``cgi.escape()``.
+
+- Issue #9409: Fix the regex to match all kind of filenames, for interactive
+  debugging in doctests.
+
+- Issue #9183: ``datetime.timezone(datetime.timedelta(0))`` will now return the
+  same instance as ``datetime.timezone.utc``.
+
+- Issue #7523: Add SOCK_CLOEXEC and SOCK_NONBLOCK to the socket module, where
+  supported by the system.  Patch by Nikita Vetoshkin.
+
+- Issue #10063: file:// scheme will stop accessing remote hosts via ftp

+  not correct, change is made to raise a URLError when a remote host is tried to
+  access via file:// scheme.
+
+- Issue #1710703: Write structures for an empty ZIP archive when a ZipFile is
+  created in modes 'a' or 'w' and then closed without adding any files. Raise
+  BadZipfile (rather than IOError) when opening small non-ZIP files.
+
+- Issue #10041: The signature of optional arguments in socket.makefile() didn't
+  match that of io.open(), and they also didn't get forwarded properly to
+  TextIOWrapper in text mode.  Patch by Kai Zhu.
+
+- Issue #9003: http.client.HTTPSConnection, urllib.request.HTTPSHandler and
+  urllib.request.urlopen now take optional arguments to allow for server

+
+What's New in Python 3.2 Alpha 3?
+=================================
+
+*Release date: 09-Oct-2010*
+
+Core and Builtins
+-----------------
+
+- Issue #10068: Global objects which have reference cycles with their module's
+  dict are now cleared again. This causes issue #7140 to appear again.
+
+- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
+  encodings.
+
+- ast.literal_eval() can now handle negative numbers.  It is also a little more
+  liberal in what it accepts without compromising the safety of the evaluation.
+  For example, 3j+4 and 3+4+5 are both accepted.
+
+- Issue #10006: type.__abstractmethods__ now raises an AttributeError.  As a
+  result metaclasses can now be ABCs (see #9533).
+
+- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
+
+- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
+  UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
+  32 bits wchar_t (eg. Linux in narrow build).
+
+- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
+  introduced by issue #9324.
+
+- Issue #9979: Create function PyUnicode_AsWideCharString().
+
+- Issue #7397: Mention that importlib.import_module() is probably what someone
+  really wants to be using in __import__'s docstring.
+
+- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
+  to use named arguments.
+
+- Issue #9930: Remove bogus subtype check that was causing (e.g.)
+  float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
+
+- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
+
+- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
+  threads are still running.  Instead, reinitialize the GIL on a second call to
+  Py_Initialize().
+
+- All SyntaxErrors now have a column offset and therefore a caret when the error
+  is printed.
+
+- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
+  module that was imported, but instead gets the module from sys.modules.
+
+- Issue #9213: The range type_items now provides index() and count() methods, to
+  conform to the Sequence ABC.  Patch by Daniel Urban and Daniel Stutzbach.
+
+- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
+  with a non-empty format string.  This is an effort to future-proof user
+  code. If a derived class does not currently implement __format__ but later
+  adds its own __format__, it would most likely break user code that had
+  supplied a format string.  This will be changed to a DeprecationWaring in
+  Python 3.3 and it will be an error in Python 3.4.
+
+- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
+  re-created on a subsequent call to Py_Initialize().  The problem (a crash)
+  wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
+
+- Issue #9210: Configure option --with-wctype-functions was removed.  Using the
+  functions from the libc caused the methods .upper() and lower() to become
+  locale aware and created subtly wrong results.
+
+- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
+  non-ASCII byte in the format string.
+
+- Issue #4617: Previously it was illegal to delete a name from the local
+  namespace if it occurs as a free variable in a nested block.  This limitation
+  of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
+
+- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
+  ``\UXXXXXXXX``, regardless of whether the character is printable or not.
+  Also, the "backslashreplace" error handler now joins surrogate pairs into a
+  single character on UCS-2 builds.
+
+- Issue #9757: memoryview objects get a release() method to release the
+  underlying buffer (previously this was only done when deallocating the
+  memoryview), and gain support for the context management protocol.
+
+- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
+  thread-local storage key.
+
+Library
+-------
+
+- Issue #2236: distutils' mkpath ignored the mode parameter.
+
+- Fix typo in one sdist option (medata-check).
+
+- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
+
+- Issue #1718574: Fix options that were supposed to accept arguments but did
+  not in build_clib.
+
+- Issue #9437: Fix building C extensions with non-default LDFLAGS.
+
+- Issue #4661: email can now parse bytes input and generate either converted
+  7bit output or bytes output.  Email version bumped to 5.1.0.
+
+- Issue #1589: Add ssl.match_hostname(), to help implement server identity
+  verification for higher-level protocols.
+
+- Issue #9759: GzipFile now raises ValueError when an operation is attempted
+  after the file is closed.  Patch by Jeffrey Finkelstein.
+
+- Issue #9042: Fix interaction of custom translation classes and caching in
+  gettext.
+
+- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
+  returning a (sock, addr) pair which is called when a connection has been
+  established with a new remote endpoint.  This is supposed to be used as a
+  replacement for old handle_accept() and avoids the user to call accept()
+  directly.
+
+- Issue #9065: tarfile no longer uses "root" as the default for the uname and
+  gname field.
+
+- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
+  an environment that does not have docutils.  Patch by Arfrever.
+
+- Issue #1050268: parseaddr now correctly quotes double quote and backslash
+  characters that appear inside quoted strings in email addresses.
+
+- Issue #10004: quoprimime no longer generates a traceback when confronted with
+  invalid characters after '=' in a Q-encoded word.
+
+- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
+  sending a 200 OK for the Expect: 100-continue request header.
+
+- Issue #9360: Cleanup and improvements to the nntplib module.  The API now
+  conforms to the philosophy of bytes and unicode separation in Python 3.  A
+  test suite has also been added.
+
+- Issue #9962: GzipFile now has the peek() method.
+
+- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
+  retry the select() loop instead of bailing out.  This is because select() can
+  incorrectly report a socket as ready for reading (for example, if it received
+  some data with an invalid checksum).
+
+- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
+
+- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
+  received.  Now sendall() properly calls signal handlers if necessary, and
+  retries sending if these returned successfully, including on sockets with a
+  timeout.
+
+- Issue #9947: logging: Fixed locking bug in stopListening.
+
+- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
+
+- Issue #9936: Fixed executable lines' search in the trace module.
+
+- Issue #9790: Rework imports necessary for samefile and sameopenfile
+  in ntpath.
+
+- Issue #9928: Properly initialize the types exported by the bz2 module.
+
+- Issue #1675951: Allow GzipFile to work with unseekable file objects.  Patch by
+  Florian Festi.
+
+- Logging: Added QueueListener class to facilitate logging usage for
+  performance-critical threads.
+
+- Issue #9916: Add some missing errno symbols.
+
+- Issue #9877: Expose sysconfig.get_makefile_filename()
+
+- logging: Added hasHandlers() method to Logger and LoggerAdapter.
+
+- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
+
+- Issue #2643: msync() is not called anymore when deallocating an open mmap
+  object, only munmap().
+
+- logging: Changed LoggerAdapter implementation internally, to make it easier to
+  subclass in a useful way.
+
+- logging: hasHandlers method was added to Logger, and isEnabledFor,
+  getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
+  LoggerAdapter was introduced into the unit tests for logging.
+
+- Issue #1686: Fix string.Template when overriding the pattern attribute.
+
+- Issue #9854: SocketIO objects now observe the RawIOBase interface in
+  non-blocking mode: they return None when an operation would block (instead of
+  raising an exception).
+
+- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
+  another kind.
+
+- Issue #9441: logging has better coverage for rotating file handlers.
+
+- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
+
+- Issue #9854: The default read() implementation in io.RawIOBase now handles
+  non-blocking readinto() returning None correctly.
+
+- Issue #1552: socket.socketpair() now returns regular socket.socket objects
+  supporting the whole socket API (rather than the "raw" _socket.socket
+  objects).
+
+- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
+  to match the corresponding socket methods.
+
+- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
+  them handle recursive calls within the same thread.
+
+- logging: Enhanced HTTPHandler with secure and credentials initializers.
+
+- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
+
+- Issue #9837: The read() method of ZipExtFile objects (as returned by
+  ZipFile.open()) could return more bytes than requested.
+
+- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
+  d['x'] = d.
+
+- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
+  it possible for the user to create self-referencing ordered dictionaries which
+  become permanently uncollectable GC garbage.  Reinstated the Python 3.1
+  approach of using weakref proxies so that reference cycles never get created
+  in the first place.
+
+- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
+  encode the value with filesystem encoding and surrogateescape (instead of
+  utf-8 in strict mode) . Patch written by David Watson.
+
+- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
+  environment variable to set the filesystem encoding at Python startup.
+  sys.setfilesystemencoding() creates inconsistencies because it is unable to
+  reencode all filenames in all objects.
+
+- Issue #9410: Various optimizations to the pickle module, leading to speedups
+  up to 4x (depending on the benchmark).  Mostly ported from Unladen Swallow;
+  initial patch by Alexandre Vassalotti.
+
+- The pprint module now supports printing OrderedDicts in their given order
+  (formerly, it would sort the keys).
+
+- Logging: Added QueueHandler class to facilitate logging usage with
+  multiprocessing.
+
+- Issue #9707: Rewritten reference implementation of threading.local which is
+  friendlier towards reference cycles.  This change is not normally visible
+  since an optimized C implementation (_thread._local) is used instead.
+
+- Issue #6394: os.getppid() is now supported on Windows.  Note that it will
+  still return the id of the parent process after it has exited.  This process
+  id may even have been reused by another unrelated process.
+
+- Issue #9792: In case of connection failure, socket.create_connection() would
+  swallow the exception and raise a new one, making it impossible to fetch the
+  original errno, or to filter timeout errors.  Now the original error is
+  re-raised.
+
+- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
+  the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
+  back after the system call.  Original patch by Brian Brazil.
+
+- Updates to the random module:
+
+  * Document which parts of the module are guaranteed to stay the same across
+    versions and which parts are subject to change.
+
+  * Update the seed() method to use all of the bits in a string instead of just
+    the hash value.  This makes better use of the seed value and assures the
+    seeding is platform independent.  Issue #7889.
+
+  * Improved the random()-->integer algorithm used in choice(), shuffle(),
+    sample(), randrange(), and randint().  Formerly, it used int(n*random())
+    which has a slight bias whenever n is not a power of two.  Issue #9025.
+
+  * Improved documentation of arguments to randrange().  Issue #9379.
+
+- collections.OrderedDict now supports a new method for repositioning keys to
+  either end.
+
+- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
+  cases now also have assertWarns and assertWarnsRegexp methods to check that a
+  given warning type was triggered by the code under test.
+
+- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
+  their contents without duplicating them.  The view is both readable and
+  writable.
+
+- Issue #7566: Implement os.path.sameopenfile for Windows.
+
+- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
+  unsupported operation is attempted (for example, writing to a file open only
+  for reading).
+
+- hashlib has two new constant attributes: algorithms_guaranteed and
+  algorithms_avaiable that respectively list the names of hash algorithms
+  guaranteed to exist in all Python implementations and the names of hash
+  algorithms available in the current process.
+
+- A new package ``concurrent.futures`` as defined by PEP 3148.
+
+C-API
+-----
+
+- Add PyErr_SyntaxLocationEx, which supports passing a column offset.
+
+- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
+  PySequence_DelSlice when the object doesn't have any mapping operations
+  defined.
+
+Tools/Demos
+-----------
+
+- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well as
+  wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
+  and the interpreter under test.
+
+Tests
+-----
+
+- Issue #9308: Added tests for importing encoded modules that do not
+  depend on specific stdlib modules being encoded in a certain way.
+
+- Issue #1051: Add a script (Lib/test/make_ssl_certs.py) to generate the custom
+  certificate and private key files used by SSL-related certs.
+
+- Issue #9978: Wait until subprocess completes initialization. (Win32KillTests
+  in test_os)
+
+- Issue #7110: regrtest now sends test failure reports and single-failure
+  tracebacks to stderr rather than stdout.
+
+- Issue #9628: fix runtests.sh -x option so more than one test can be excluded.
+
+- Issue #9899: Fix test_tkinter.test_font on various platforms.  Patch by Ned
+  Deily.
+
+- Issue #9894: Do not hardcode ENOENT in test_subprocess.
+
+- Issue #9315: Added tests for the trace module.  Patch by Eli Bendersky.
+
+- Issue #9323: Make test.regrtest.__file__ absolute, this was not always the
+  case when running profile or trace, for example.
+
+- Issue #9568: Fix test_urllib2_localnet on OS X 10.3.
+
+Build
+-----
+
+- Issue #10062: Allow building on platforms which do not have sem_timedwait.
+
+- Issue #10054: Some platforms provide uintptr_t in inttypes.h.  Patch by Akira
+  Kitada.
+
+- Issue #10055: Make json C89-compliant in UCS4 mode.
+
+- Issue #9552: Avoid unnecessary rebuild of OpenSSL. (Windows)
+
+- Issue #1633863: Don't ignore $CC under AIX.
+
+- Issue #9810: Compile bzip2 source files in Python's project file directly. It
+  used to be built with bzip2's makefile.
+
+- Issue #9848: Stopping trying to build _weakref in setup.py as it is a built-in
+  module.
+
+- Issue #9806: python-config now has an ``--extension-suffix`` option that
+  outputs the suffix for dynamic libraries including the ABI version name
+  defined by PEP 3149.
+
+- Issue #941346: Improve the build process under AIX and allow Python to be
+  built as a shared library.  Patch by Sébastien Sablé.

+  feature now also supports the ZSH shell.
+
+
+What's New in Python 3.2 Alpha 2?
+=================================
+
+*Release date: 05-Sep-2010*
+
+Core and Builtins
+-----------------
+
+- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
+  the new (and simpler) DUP_TOP_TWO.  Performance isn't changed, but our
+  bytecode is a bit simplified.  Patch by Demur Rumed.
+
+- Issue #9766: Rename poorly named variables exposed by _warnings to prevent
+  confusion with the proper variables names from 'warnings' itself.
+
+- Issue #9212: dict_keys and dict_items now provide the isdisjoint() method, to
+  conform to the Set ABC.  Patch by Daniel Urban.
+
+- Issue #9737: Fix a crash when trying to delete a slice or an item from a
+  memoryview object.
+
+- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
+  now removed, since their effect was inexistent in 3.x (the default encoding is
+  hardcoded to utf-8 and cannot be changed).
+
+- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
+  properly.  Patch by Stefan Behnel.
+
+- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
+  platforms.  Previously, it inlined only when using Microsoft Visual C.
+
+- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
+
+- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
+
+- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
+  the pyconfig.h generated by configure on other systems.
+
+- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
+  occur during attribute lookup are now propagated to the caller.
+
+- Issue #8622: Add PYTHONFSENCODING environment variable to override the
+  filesystem encoding.
+
+- Issue #5127: The C functions that access the Unicode Database now accept and
+  return characters from the full Unicode range, even on narrow unicode builds
+  (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others).  A visible difference
+  in Python is that unicodedata.numeric() now returns the correct value for
+  large code points, and repr() may consider more characters as printable.
+
+- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
+  as a unicode object, instead of a byte string. Function needed to support
+  unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
+  function.
+
+- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().
+
+- Issue #9612: The set object is now 64-bit clean under Windows.
+
+- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
+  the module file to be executed with the -m command line option.
+
+- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions to
+  write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
+  sys.stderr.
+
+- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
+  decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
+  objects are output as-is.
+
+- Issue #9203: Computed gotos are now enabled by default on supported compilers
+  (which are detected by the configure script).  They can still be disable
+  selectively by specifying --without-computed-gotos.
+
+- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
+  use PyUnicode_FromFormatV() to format the warning message.
+
+- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
+  array.
+
+- Issue #5319: Print an error if flushing stdout fails at interpreter shutdown.
+
+- Issue #9337: The str() of a float or complex number is now identical to its
+  repr().
+
+- Issue #9416: Fix some issues with complex formatting where the output with no
+  type specifier failed to match the str output:
+
+    - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
+    - format(complex(0.0, 2.0), '-') included a sign and parentheses.
+
+Extension Modules
+-----------------
+
+- Issue #8013: time.asctime and time.ctime no longer call system
+  asctime and ctime functions.  The year range for time.asctime is now
+  1900 through maxint.  The range for time.ctime is the same as for
+  time.localtime.  The string produced by these functions is longer
+  than 24 characters when year is greater than 9999.
+
+- Issue #6608: time.asctime is now checking struct tm fields its input
+  before passing it to the system asctime.  Patch by MunSic Jeong.

+  descriptor is provided.  Patch by Pascal Chambon.
+
+- Issue #7736: Release the GIL around calls to opendir() and closedir() in the
+  posix module.  Patch by Marcin Bachry.
+
+- Issue #4835: make PyLong_FromSocket_t() and PyLong_AsSocket_t() private to the
+  socket module, and fix the width of socket descriptors to be correctly
+  detected under 64-bit Windows.
+
+- Issue #1027206: Support IDNA in gethostbyname, gethostbyname_ex, getaddrinfo
+  and gethostbyaddr.  getnameinfo is now restricted to numeric addresses as

+  into the closed state without closing the underlying file descriptor.
+
+- Issue #477863: Emit a ResourceWarning at shutdown if gc.garbage is not empty.

+  a tuple subclass.
+
+- Issue #9324: Add parameter validation to signal.signal on Windows in order to
+  prevent crashes.

+  module from working correctly with arrays of more than 2**31 elements.
+
+- Fix memory leak in ssl._ssl._test_decode_cert.
+
+- Issue #8065: Fix memory leak in readline module (from failure to free the
+  result of history_get_history_state()).

+  array.frombytes(), array.extend() as well as the array.array() constructor now
+  accept bytearray objects.  Patch by Thomas Jollans.
+

+  issues when socket.close is called from a __del__ method.
+
+- Issue #9706: ssl module provides a better error handling in various
+  circumstances.
+
+- Issue #1868: Eliminate subtle timing issues in thread-local objects by getting

+  structure.
+
+- Issue #8866: parameters passed to socket.getaddrinfo can now be specified as
+  single keyword arguments.
+
+- Address XXX comment in dis.py by having inspect.py prefer to reuse the dis.py

+What's New in Python 3.2 Alpha 1?
+=================================
+
+*Release date: 01-Aug-2010*
+
+Core and Builtins
+-----------------
+
+- Issue #8991: convertbuffer() rejects discontigious buffers.
+
+- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
+  compiler.
+
+- Issue #8413: structsequence now subclasses tuple.
+
+- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
+  start byte and the continuation byte(s) are now considered invalid, instead of
+  the number of bytes specified by the start byte.  E.g.:
+  '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
+  with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
+  even if '\xf1' is the start byte of a 4-bytes sequence.  Previous versions
+  returned a single u'\ufffd'.
+
+- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
+  rather than 0.0.  So "-7j" is now exactly equivalent to "-(7j)".
+
+- Be more specific in error messages about positional arguments.
+
+- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
+  objects, as described in the documentation.

+  dealing with unary minus applied to a constant.  The removed code was mutating
+  the ST, causing a second compilation to fail.
+
+- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
+  mode raises unicode errors.  The encoder only supports "strict" and "replace"
+  error handlers, the decoder only supports "strict" and "ignore" error
+  handlers.  Patch written by Mark Hammond.
+
+- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
+  "w*" format instead. Add tests for "w*" format.
+
+- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
+  formats if the string contains a null byte/character.  Write unit tests for
+  string formats.
+
+- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
+  suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
+  location of the raised exception.
+
+- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
+  filenames and enable os.fsencode().
+
+- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
+
+- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
+  interpreter with characters outside the Basic Multilingual Plane (higher than
+  0x10000).
+
+- Issue #8950: (See also issue #5080).  Py_ArgParse*() functions now raise
+  TypeError instead of giving a DeprecationWarning when a float is parsed using
+  the 'L' code (for long long).  (All other integer codes already raise
+  TypeError in this case.)
+
+- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
+  enable shortcuts for upper case encoding name. Add also a shortcut for
+  "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
+
+- Issue #8838: Remove codecs.charbuffer_encode() function.  The buffer protocol
+  doesn't support "char buffer" anymore in Python 3.
+
+- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
+  instead.  codecs.charbuffer_encode() now accepts modifiable buffer objects
+  like bytearray.
+
+- Issue #8837: Remove "O?" format of PyArg_Parse*() functions.  The format is no
+  used anymore and it was never documented.
+
+- In str.format(), raise a ValueError when indexes to arguments are too large.
+
+- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
+  integers n (including n = -909).
+
+- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
+  of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
+  easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
+  equal value.
+
+- Issue #8748: Fix two issues with comparisons between complex and integer
+  objects.  (1) The comparison could incorrectly return True in some cases
+  (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
+  (2) The comparison raised an OverflowError for large integers, leading to
+  unpredictable exceptions when combining integers and complex objects in sets
+  or dicts.
+
+- Issue #8766: Initialize _warnings module before importing the first module.
+  Fix a crash if an empty directory called "encodings" exists in sys.path.
+
+- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
+  encoding and surrogateescape error handler instead of the locale encoding to
+  be consistent with os.environ.  Add PySys_AddWarnOptionUnicode() function.
+
+- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
+  of strict) error handler to escape surrogates.
+
+- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
+  object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
+  handler, and return bytes.  If Py_FileSystemDefaultEncoding is not set, fall
+  back to UTF-8.
+
+- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
+  error handler, not only the default error handler (strict).
+
+- Issue #8610: Load file system codec at startup, and display a fatal error on
+  failure.  Set the file system encoding to utf-8 (instead of None) if getting
+  the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
+
+- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
+  PyUnicode_FromString() to support surrogates in the filename and use the right
+  encoding.
+
+- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
+
+- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
+
+- Issue #8419: Prevent the dict constructor from accepting non-string keyword
+  arguments.
+
+- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute

+  (KeyboardInterrupt).
+
+- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
+  unicode string (eg. backslashreplace).
+
+- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
+  anymore, you have to convert your bytearray filenames to bytes.
+
+- Issue #7332: Remove the 16KB stack-based buffer in
+  PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
+  compared to the dynamic memory allocation fallback.  Patch by Charles-François
+  Natali.
+
+- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
+  passed to bytes or bytearray.

+  changed.
+
+- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
+  64-bit machines.  The shift count for either left or right shift is permitted
+  to be up to sys.maxsize.
+
+- Ensure that tokenization of identifiers is not affected by locale.
+
+- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

+- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
+
+- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
+  is set.

+- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
+  is unknown.
+
+- Issue #1583863: A str subclass can now override the __str__ method.
+
+- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
+  PyMemberDefs could produce an internal error; raise TypeError instead.
+
+- Issue #7845: Rich comparison methods on the complex type now return
+  NotImplemented rather than raising a TypeError when comparing with an
+  incompatible type; this allows user-defined classes to implement their own
+  comparisons with complex.
+
+- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
+  (SIGINT). If an error occurs while importing the site module, the error is
+  printed and Python exits. Initialize the GIL before importing the site module.
+
+- Issue #7173: Generator finalization could invalidate sys.exc_info().
+
+- Issue #7544: Preallocate thread memory before creating the thread to avoid a

+  Now it matches other numeric types.
+
+- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,

+- Issue #7385: Fix a crash in `MemoryView_FromObject` when `PyObject_GetBuffer`
+  fails.  Patch by Florent Xicluna.
+
+- Issue #7788: Fix an interpreter crash produced by deleting a list slice with
+  very large step value.
+
+- Issue #7766: Change sys.getwindowsversion() return value to a named tuple and
+  add the additional members returned in an OSVERSIONINFOEX structure.  The new
+  members are service_pack_major, service_pack_minor, suite_mask, and
+  product_type.
+
+- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
+  crash in many places because of the PyByteArray_AS_STRING() macro returning
+  NULL.  The macro now returns a statically allocated empty string instead.
+
+- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
+  where the right hand operand is a set of constants, by turning the set into a
+  frozenset and pre-building it as a constant.  The comparison operation is made
+  against the constant instead of building a new set each time it is executed (a
+  similar optimization already existed which turned a list of constants into a
+  pre-built tuple).  Patch and additional tests by Dave Malcolm.
+
+- Issue #7622: Improve the split(), rsplit(), splitlines() and replace() methods
+  of bytes, bytearray and unicode objects by using a common implementation based
+  on stringlib's fast search.  Patch by Florent Xicluna.
+
+- Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2,
+  including: (1) a serious 'wrong output' bug that could occur for long (> 40
+  digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
+  parsing certain long numeric strings corresponding to subnormal values, (3) a
+  memory leak for some values large enough to cause overflow, and (4) a number
+  of flaws that could lead to incorrectly rounded results.
+
+- The __complex__ method is now looked up on the class of instances to make it
+  consistent with other special methods.
+
+- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
+  `rindex`, `rsplit` and `rpartition` methods.  Patch by Florent Xicluna.
+
+- Issue #7604: Deleting an unset slotted attribute did not raise an
+  AttributeError.
+
+- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
+  in ** operator.  The behaviour now conforms to that described in C99 Annex F.
+
+- Issue #1811: improve accuracy and cross-platform consistency for true division
+  of integers: the result of a/b is now correctly rounded for ints a and b (at
+  least on IEEE 754 platforms), and in particular does not depend on the
+  internal representation of an int.
+
+- Issue #6834: replace the implementation for the 'python' and 'pythonw'
+  executables on OSX.
+
+  These executables now work properly with the arch(1) command: ``arch -ppc
+  python`` will start a universal binary version of python in PPC mode (unlike
+  previous releases).
+
+- Issue #7466: Segmentation fault when the garbage collector is called in the
+  middle of populating a tuple.  Patch by Florent Xicluna.
+
+- Issue #7419: setlocale() could crash the interpreter on Windows when called
+  with invalid values.
+
+- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"

+
+- Issue #6970: Remove redundant calls when comparing objects that don't
+  implement the relevant rich comparison methods.
+
+- Issue #7298: Fixes for range and reversed(range(...)).  Iteration over
+  range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
+  long but the length of the range did not.  Also fix several cases where
+  reversed(range(a, b, c)) gave wrong results, and fix a refleak for
+  reversed(range(a, b, c)) with large arguments.
+
+- Issue #7244: itertools.izip_longest() no longer ignores exceptions raised
+  during the formation of an output tuple.
+
+- Issue #3297: On wide unicode builds, do not split unicode characters into
+  surrogates.
+
+- Remove length limitation when constructing a complex number from a string.
+
+- Issue #1087418: Boost performance of bitwise operations for longs.
+
+- Support for AtheOS has been completely removed from the code base. It was
+  disabled since Python 3.0.
+
+- Support for several legacy threading libraries has been disabled. These
+  libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
+  will be entirely removed in 3.3.
+
+- Support for OSF* has been disabled. If nobody stands up, support will be
+  removed in 3.3. See <http://bugs.python.org/issue8606>.
+
+- Peephole constant folding had missed UNARY_POSITIVE.
+
+- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

+  support.
+
+- Issue #7120: logging: Removed import of multiprocessing which is causing crash

+
+- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when using
+  byte values greater than 127.  Patch by Derk Drukker.
+
+- Issue #1571184: The Unicode database contains properties for more characters.
+  The tables for code points representing numeric values, white spaces or line
+  breaks are now generated from the official Unicode Character Database files,
+  and include information from the Unihan.txt file.
+
+- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of

+
+- Issue #1616979: Added the cp720 (Arabic DOS) encoding.
+
+- Issue #6428: Since Python 3.0, the __bool__ method must return a bool object,
+  and not an int.  Fix the corresponding error message, and the documentation.
+
+- The deprecated PyCObject has been removed.
+
+- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.  This fixes a

+
+- Code objects now support weak references.
+
+- Issue #7072: isspace(0xa0) is true on Mac OS X.
+
+- Issue #8084: PEP 370 now conforms to system conventions for framework builds

+
+C-API
+-----
+
+- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
+  variable argument list.  `Py_VA_COPY` is equivalent to C99
+  `va_copy`, but available on all python platforms.
+
+- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
+  instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX].  This makes it safe to do
+  "step = -step" when reversing a slice.
+
+- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
+  interpreter to set sys.argv without also modifying sys.path.  This helps fix
+  `CVE-2008-5983
+  <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
+
+- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
+  strings in an efficient manner.
+
+- Issue #8276: PyEval_CallObject() is now only available in macro form.  The
+  function declaration, which was kept for backwards compatibility reasons, is
+  now removed (the macro was introduced in 1997!).
+
+- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to
+  PyLong_AsLongAndOverflow.
+
+- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
+  has '\0' at the end.
+
+- Issue #5080: The argument parsing functions PyArg_ParseTuple,
+  PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
+  PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
+  'L' format code.  This will become a TypeError in a future version of Python,
+  to match the behaviour of the other integer format codes.
+
+- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
+
+- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments) in
+  PyArg_ParseTupleAndKeywords.
+
+- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V) and
+  PyErr_Format, on machines with HAVE_LONG_LONG defined.
+
+- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
+  PEP 3123).  The PyDescr_TYPE and PyDescr_NAME macros should be should used for
+  accessing the d_type and d_name members of structures using PyDescr_COMMON.
+
+- Issue #6405: Remove duplicate type declarations in descrobject.h.
+
+- The code flags for old __future__ features are now available again.
+
+- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
+  PyCode_Addr2Line().
+
+- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
+  object at a specified file, function, and line number.
+
+- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
+  ``const char *`` as the string is stored beyond the call.
+
+- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
+  allocator will be automatically disabled when running under Valgrind.  This
+  gives improved memory leak detection when running under Valgrind, while taking
+  advantage of pymalloc at other times.
+
+Library
+-------
+
+- In pdb, when Ctrl-C is entered while defining commands for a breakpoint, the
+  old commands are restored.
+
+- For traceback debugging, the pdb listing now also shows the locations where
+  the exception was originally (re)raised, if it differs from the last line
+  executed (e.g. in case of finally clauses).
+

+  before ASCII-to-binary decoding.
+
+- Issue #9384: ``python -m tkinter`` will now display a simple demo applet.
+
+- The default size of the re module's compiled regular expression cache has been
+  increased from 100 to 500 and the cache replacement policy has changed from
+  simply clearing the entire cache on overflow to forgetting the least recently
+  used cached compiled regular expressions.  This is a performance win for
+  applications that use a lot of regular expressions and limits the impact of
+  the performance hit anytime the cache is exceeded.
+
+- Issue #7113: Speed up loading in configparser. Patch by Łukasz Langa.
+
+- Issue #9032: XML-RPC client retries the request on EPIPE error.  The EPIPE
+  error occurs when the server closes the socket and the client sends a big
+  XML-RPC request.
+
+- Issue #4629: getopt raises an error if an argument ends with "=", whereas
+  getopt doesn't accept a value (eg. --help= is rejected if getopt uses
+  ['help='] long options).
+
+- Issue #7989: Added pure python implementation of the `datetime` module.  The C
+  module is renamed to `_datetime` and if available, overrides all classes
+  defined in datetime with fast C impementation.  Python implementation is based
+  on the original python prototype for the datetime module by Tim Peters with
+  minor modifications by the PyPy project.  The test suite now tests `datetime`
+  module with and without `_datetime` acceleration using the same test cases.
+
+- Issue #7895: platform.mac_ver() no longer crashes after calling os.fork().

+
+- Issue #8784: Set tarfile default encoding to 'utf-8' on Windows.
+
+- Issue #8966: If a ctypes structure field is an array of c_char, convert its
+  value to bytes instead of str (as done for c_char and c_char_p).
+
+- Issue #8188: Comparisons between Decimal and Fraction objects are now
+  permitted, returning a result based on the exact numerical values of the
+  operands.  This builds on issue #2531, which allowed Decimal-to-float
+  comparisons; all comparisons involving numeric types (bool, int, float,
+  complex, Decimal, Fraction) should now act as expected.
+

+  mistake.
+
+- Charset.body_encode now correctly handles base64 encoding by encoding with the

+
+- Issue #8845: sqlite3 Connection objects now have a read-only in_transaction
+  attribute that is True iff there are uncommitted changes.
+
+- Issue #1289118: datetime.timedelta objects can now be multiplied by float and

+  Fredrik Håård.
+
+- Issue #8540: Decimal module: rename the Context._clamp attribute to

+  correspond to the decimal interchange formats specified in IEEE 754.
+
+- Issue #6268: Fix seek() method of codecs.open(), don't read or write the BOM
+  twice after seek(0). Fix also reset() method of codecs, UTF-16, UTF-32 and
+  StreamWriter classes.
+
+- Issue #3798: sys.exit(message) writes the message to sys.stderr file, instead

+
+- Issue #8759: Fixed user paths in sysconfig for posix and os2 schemes.
+
+- Issue #8663: distutils.log emulates backslashreplace error handler. Fix

+  stdout is not a TTY).
+
+- Issue #8513: os.get_exec_path() supports b'PATH' key and bytes value.

+  class.
+
+- Issue #8664: In py_compile, create __pycache__ when the compiled path is

+  larger than 1GB with the zlib module's compressor and decompressor objects.
+
+- Issue #8603: Support bytes environmental variables on Unix: Add os.environb

+
+- Issue #8573: asyncore _strerror() function might throw ValueError.
+
+- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error

+
+- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
+  Patch by Tres Seaver.
+
+- Issue #8390: tarfile uses surrogateescape as the default error handler
+  (instead of replace in read mode or strict in write mode).
+
+- Issue #7755: Use an unencumbered audio file for tests.
+
+- Issue #8621: uuid.uuid4() returned the same sequence of values in the parent
+  and any children created using ``os.fork`` on MacOS X 10.6.
+
+- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
+  operation raises multiple signals and more than one of those signals is
+  trapped, the specification determines the order in which the signals should be
+  handled.  In many cases this order wasn't being followed, leading to the wrong
+  Python exception being raised.
+
+- Issue #7865: The close() method of ``io`` objects should not swallow
+  exceptions raised by the implicit flush().  Also qensure that calling close()

+  and mappings.
+
+- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where

+  started running.  This also fixes the occasional freezes witnessed in
+  test_httpservers.
+
+- Issue #8524: When creating an SSL socket, the timeout value of the original
+  socket wasn't retained (instead, a socket with a positive timeout would be
+  turned into a non-blocking SSL socket).
+
+- Issue #5103: SSL handshake would ignore the socket timeout and block
+  indefinitely if the other end didn't respond.
+
+- The do_handshake() method of SSL objects now adjusts the blocking mode of the
+  SSL structure if necessary (as other methods already do).
+
+- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and
+  bytes strings for environment keys and values.
+
+- Issue #8467: Pure Python implementation of subprocess encodes the error

+
+- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
+  string "python" as the *ident*.  openlog() arguments are all optional and
+  keywords.
+
+- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
+  non-infinite timeout.  Also make that method friendlier with applications
+  wanting to continue using the socket in clear-text mode, by disabling
+  OpenSSL's internal readahead.  Thanks to Darryl Miles for guidance.

+
+- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
+
+- Issue #7316: The acquire() method of lock objects in the ``threading``
+  module now takes an optional timeout argument in seconds.  Timeout support
+  relies on the system threading library, so as to avoid a semi-busy wait loop.
+
+- Issue #8383: pickle and pickletools use surrogatepass error handler when
+  encoding unicode as utf8 to support lone surrogates and stay compatible with
+  Python 2.x and 3.x.
+
+- Issue #7585: difflib context and unified diffs now place a tab between
+  filename and date, conforming to the 'standards' they were originally designed
+  to follow.  This improves compatibility with patch tools.
+
+- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
+  character sets will now consistently use a Content-Transfer-Encoding of 7bit
+  rather than sometimes being marked as 8bit.
+
+- Issue #8375: test_distutils now checks if the temporary directory are still

+- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
+  using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
+  `ssl.OPENSSL_VERSION_NUMBER`.
+
+- Add functools.total_ordering() and functools.cmp_to_key().
+
+- Issue #8257: The Decimal construct now accepts a float instance directly,
+  converting that float to a Decimal of equal value:
+
+     >>> Decimal(1.1)
+     Decimal('1.100000000000000088817841970012523233890533447265625')
+
+- Issue #8294: The Fraction constructor now accepts Decimal and float instances
+  directly.
+
+- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
+  InvalidOperation instead of returning False.  (Comparisons involving a quiet
+  NaN are unchanged.)  Also, Decimal quiet NaNs are now hashable; Decimal
+  signaling NaNs remain unhashable.
+
+- Issue #2531: Comparison operations between floats and Decimal instances now
+  return a result based on the numeric values of the operands; previously they
+  returned an arbitrary result based on the relative ordering of id(float) and
+  id(Decimal).  See also issue #8188, which adds Decimal-to-Fraction
+  comparisons.
+
+- Added a subtract() method to collections.Counter().
+
+- Issue #8233: When run as a script, py_compile.py optionally takes a single
+  argument `-` which tells it to read files to compile from stdin.  Each line is
+  read on demand and the named file is compiled immediately.  (Original patch by
+  Piotr Ożarowski).
+
+- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
+  form feed (0x0C) are now considered linebreaks, as specified in Unicode
+  Standard Annex #14.  See issue #7643.  http://www.unicode.org/reports/tr14/
+
+- Comparisons using one of <, <=, >, >= between a complex instance and a
+  Fractions instance now raise TypeError instead of returning True/False.  This
+  makes Fraction <=> complex comparisons consistent with int <=> complex, float
+  <=> complex, and complex <=> complex comparisons.
+
+- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some
+  methods (such as oss_mixer_device.fileno()) were not available.  Initial patch
+  by Bertrand Janin.
+
+- Issue #8205: Remove the "Modules" directory from sys.path when Python is
+  running from the build directory (POSIX only).
+
+- Issue #7512: shutil.copystat() could raise an OSError when the filesystem

+  silenced.
+
+- Issue #7860: platform.uname now reports the correct 'machine' type when Python
+  is running in WOW64 mode on 64 bit Windows.
+
+- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.

+
+- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
+  locale.
+
+- The internals of the subprocess module on POSIX systems have been replaced by
+  an extension module (_posixsubprocess) so that the fork()+exec() can be done
+  safely without the possibility of deadlock in multithreaded applications.
+
+- subprocess.Popen now has restore_signals and start_new_session features.  The
+  default of restore_signals=True is a new behavior compared to earlier Python
+  versions.  This means that signals such as SIGPIPE are not ignored by default
+  in subprocesses launched by Python (Issue #1652).
+
+- Issue #6472: The xml.etree package is updated to ElementTree 1.3.  The
+  cElementTree module is updated too.
+

+
+- Issue #7633: In the decimal module, Context class methods (with the exception
+  of canonical and is_canonical) now accept instances of int and long wherever a
+  Decimal instance is accepted, and implicitly convert that argument to Decimal.
+  Previously only some arguments were converted.
+
+- Issue #7835: shelve should no longer produce mysterious warnings during
+  interpreter shutdown.
+
+- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in XML
+  processing instructions and comments.  These raw characters are allowed by the
+  XML specification, and are necessary when outputting e.g.  PHP code in a
+  processing instruction.  Patch by Neil Muller.
+
+- Issue #6233: ElementTree failed converting unicode characters to XML entities
+  when they could't be represented in the requested output encoding.  Patch by
+  Jerry Chen.
+
+- Issue #6003: add an argument to ``zipfile.Zipfile.writestr`` to specify the
+  compression type.
+
+- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
+  specified, rather than fall through to AF_PACKET (in the `socket` module).
+  Also, raise ValueError rather than TypeError when an unknown TIPC address type
+  is specified.  Patch by Brian Curtin.
+
+- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
+  position when calling `truncate()`.  It would previously change the file
+  position to the given argument, which goes against the tradition of
+  ftruncate() and other truncation APIs.  Patch by Pascal Chambon.
+
+- Issue #7610: Reworked implementation of the internal
+  ``zipfile.ZipExtFile`` class used to represent files stored inside an
+  archive.  The new implementation is significantly faster and can be wrapped in
+  a ``io.BufferedReader`` object for more speedups.  It also solves an
+  issue where interleaved calls to `read()` and `readline()` give wrong results.
+  Patch by Nir Aides.
+
+- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

+  access to the initgroups(3) C library call on Unix systems which implement it.
+  Patch by Jean-Paul Calderone.
+
+- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
+  ownership when the group is not forced, because the group may be different
+  from the user's group and inherit from its container when the test is run.
+
+- Issue #4486: When an exception has an explicit cause, do not print its
+  implicit context too.  This affects the `traceback` module as well as built-in
+  exception printing.
+
+- Issue #1515: Enable use of deepcopy() with instance methods.  Patch by Robert
+  Collins.
+
+- Issue #7403: logging: Fixed possible race condition in lock creation.

+  argument.  Patch by Pablo Mouzo.
+
+- Issue #5788: `datetime.timedelta` objects get a new `total_seconds()` method
+  returning the total number of seconds in the duration.  Patch by Brian
+  Quinlan.

+
+- Issue #4969: The mimetypes module now reads the MIME database from the
+  registry under Windows.  Patch by Gabriel Genellina.
+
+- Issue #6816: runpy now provides a run_path function that allows Python code to
+  execute file paths that refer to source or compiled Python files as well as
+  zipfiles, directories and other valid sys.path entries that contain a
+  __main__.py file.  This allows applications that run other Python scripts to
+  support the same flexibility as the CPython command line itself.
+
+- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
+  connection with another process, rather than looping endlessly.  The default
+  timeout is 20 seconds, which should be amply sufficient for local connections.
+
+- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and
+  unpickled.  This fixes crashes under Windows when trying to run
+  test_multiprocessing in verbose mode.
+
+- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
+  argument added to the TextTestRunner constructor allowing a different result
+  class to be used without having to subclass.
+
+- Issue #7588: ``unittest.TextTestResult.getDescription`` now includes the test
+  name in failure reports even if the test has a docstring.
+
+- Issue #3001: Add a C implementation of recursive locks which is used by
+  default when instantiating a `threading.RLock` object. This makes recursive
+  locks as fast as regular non-recursive locks (previously, they were slower by
+  10x to 15x).
+
+- Issue #7282: Fix a memory leak when an RLock was used in a thread other than
+  those started through `threading.Thread` (for example, using

+  modification is done through it.  This fixes inconsistencies and test failures
+  on systems with slightly bogus mtime behaviour.
+
+- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
+  from stdin so that existing input does not confuse it and lead to incorrect
+  entry or an IOError.  It also properly flushes it afterwards to avoid the
+  terminal echoing the input afterwards on OSes such as Solaris.
+
+- Issue #7233: Fix a number of two-argument Decimal methods to make sure that
+  they accept an int or long as the second argument.  Also fix buggy handling of
+  large arguments (those with coefficient longer than the current precision) in
+  shift and rotate.
+
+- Issue #4750: Store the basename of the original filename in the gzip FNAME
+  header as required by RFC 1952.

+
+- Issue #6850: Fix bug in Decimal._parse_format_specifier for formats with no
+  type specifier.
+
+- Issue #6239: ctypes.c_char_p return value must return bytes.
+
+- Issue #6838: Use a list to accumulate the value instead of repeatedly
+  concatenating strings in http.client's HTTPResponse._read_chunked providing a
+  significant speed increase when downloading large files servend with a

+
+- Trying to import a submodule from a module that is not a package, ImportError
+  should be raised, not AttributeError.
+
+- When the globals past to importlib.__import__() has __package__ set to None,

+  working through proxy.  Original patch by Christopher Li, changes made by
+  Senthil Kumaran.
+
+- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
+  loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
+  PyPycLoader inherit from this class and provide implementations in relation to
+  other methods required by the ABCs.
+
+- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
+  the documentation said it did even though the code in PyLoader relied on the
+  abstract method required by ResourceLoader.
+
+- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

+  for tracing methods.
+
+Extension Modules
+-----------------
+
+- Issue #9959: Tweak formula used for computing math.log of an integer,
+  making it marginally more accurate for exact powers of 2.
+
+- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
+
+- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
+  compared to other unix systems. In particular, os.getgroups() does not reflect
+  any changes made using os.setgroups() but basicly always returns the same
+  information as the id command. os.getgroups() can now return more than 16
+  groups on MacOSX.
+
+- Issue #6095: Make directory argument to os.listdir optional.
+
+- Issue #9277: Fix bug in struct.pack for bools in standard mode (e.g.,
+  struct.pack('>?')): if conversion to bool raised an exception then that
+  exception wasn't properly propagated on machines where char is unsigned.
+
+- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
+  they contain instances of old-style classes.
+
+- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany
+  existing isinf and isnan functions.
+
+- Issue #1578269: Implement os.symlink for Windows 6.0+.  Patch by Jason
+  R. Coombs.
+
+- In struct.pack, correctly propogate exceptions from computing the truth of an
+  object in the '?' format.
+
+- Issue #9000: datetime.timezone objects now have eval-friendly repr.
+
+- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
+  special methods.
+
+- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
+  Prior to this change, timezone adjustment in utctimetuple() could produce
+  tm_year value of 0 or 10,000.  Now an OverflowError is raised in these edge
+  cases.
+
+- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
+  directive.  When the ``%z`` directive is present in the format string, an
+  aware ``datetime`` object is returned with ``tzinfo`` bound to a
+  ``datetime.timezone`` instance constructed from the parsed offset.  If both
+  ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
+  name, but ``%Z`` data without ``%z`` is discarded.
+
+- Issue #5094: The ``datetime`` module now has a simple concrete class
+  implementing ``datetime.tzinfo`` interface.  Instances of the new class,
+  ``datetime.timezone``, return fixed name and UTC offset from their
+  ``tzname(dt)`` and ``utcoffset(dt)`` methods.  The ``dst(dt)`` method always
+  returns ``None``.  A class attribute, ``utc`` contains an instance
+  representing the UTC timezone.  Original patch by Rafe Kaplan.
+
+- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
+  includes documentation for the struct.Struct class.
+
+- Issue #3129: Trailing digits in struct format string are no longer ignored.
+  For example, "1" or "ilib123" are now invalid formats and cause
+  ``struct.error`` to be raised.  Patch by Caleb Deveraux.
+
+- Issue #7384: If the system readline library is linked against ncurses, the
+  curses module must be linked against ncurses as well. Otherwise it is not safe
+  to load both the readline and curses modules in an application.
+
+- Issue #2810: Fix cases where the Windows registry API returns ERROR_MORE_DATA,
+  requiring a re-try in order to get the complete result.
+
+- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
+  with an improved 'binary-split' algorithm that uses fewer multiplications and
+  allows many of the multiplications to be performed using plain C integer
+  arithmetic instead of PyLong arithmetic.  Also uses a lookup table for small
+  arguments.
+
+- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
+  overflow checks in the audioop module.
+
+- Issue #8644: The accuracy of td.total_seconds() has been improved (by
+  calculating with integer arithmetic instead of float arithmetic internally):
+  the result is now always correctly rounded, and is equivalent to ``td /
+  timedelta(seconds=1)``.
+
+- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /
+  timedelta, timedelta % timedelta, timedelta // timedelta and divmod(timedelta,
+  timedelta) are all supported.
+
+- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
+
+- Issue #8300: When passing a non-integer argument to struct.pack with any
+  integer format code, struct.pack first attempts to convert the non-integer
+  using its __index__ method.  If that method is non-existent or raises
+  TypeError it goes on to try the __int__ method, as described below.
+
+- Issue #8142: Update libffi to the 3.0.9 release.
+
+- Issue #6949: Allow the _dbm extension to be built with db 4.8.x.
+
+- Issue #6544: Fix a reference leak in the kqueue implementation's error
+  handling.
+
+- Stop providing crtassem.h symbols when compiling with Visual Studio 2010, as
+  msvcr100.dll is not a platform assembly anymore.
+
+- Issue #6508: Add posix.{getresuid,getresgid,setresuid,setresgid}.
+
+- Issue #7078: Set struct.__doc__ from _struct.__doc__.
+
+- Issue #3366: Add erf, erfc, expm1, gamma, lgamma functions to math module.
+
+- Issue #6877: It is now possible to link the readline extension to the libedit
+  readline emulation on OSX 10.5 or later.
+
+- Issue #6848: Fix curses module build failure on OS X 10.6.
+
+- Fix a segfault that could be triggered by expat with specially formed input.
+
+- Issue #6561: '\d' in a regex now matches only characters with Unicode category
+  'Nd' (Number, Decimal Digit).  Previously it also matched characters with
+  category 'No'.
+
+- Issue #4509: Array objects are no longer modified after an operation failing
+  due to the resize restriction in-place when the object has exported buffers.
+
+- Issue #2389: Array objects are now pickled in a portable manner.
+
+- Expat: Fix DoS via XML document with malformed UTF-8 sequences
+  (CVE_2009_3560).
+
+- Issue #7242: On Solaris 9 and earlier calling os.fork() from within a thread
+  could raise an incorrect RuntimeError about not holding the import lock.  The
+  import lock is now reinitialized after fork.
+
+- Issue #7999: os.setreuid() and os.setregid() would refuse to accept a -1
+  parameter on some platforms such as OS X.
+
+- Build the ossaudio extension on GNU/kFreeBSD.
+
+- Issue #7347: winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
+  the return value of QueryReflectionKey.
+
+- Issue #7567: PyCurses_setupterm: Don't call ``setupterm`` twice.
+
+Build
+-----
+
+- Use OpenSSL 1.0.0a on Windows.
+
+- Issue #9280: Make sharedinstall depend on sharedmods.
+
+- Issue #9189: Make a user-specified CFLAGS, CPPFLAGS, or LDFLAGS setting
+  override the configure and makefile defaults, without deleting options the
+  user didn't intend to override.  Developers should no longer need to specify
+  OPT or EXTRA_CFLAGS, although those variables are still present for
+  backward-compatibility.
+
+- Issue #8854: Fix finding Visual Studio 2008 on Windows x64.
+
+- Issue #1759169, #8864: Drop _XOPEN_SOURCE on Solaris, define it for
+  multiprocessing only.
+
+- Issue #8625: Turn off optimization in --with-pydebug builds with gcc.
+  (Optimization was unintentionally turned on in gcc --with-pydebug builds as a
+  result of the issue #1628484 fix, combined with autoconf's strange choice of
+  default CFLAGS produced by AC_PROG_CC for gcc.)
+
+- Issue #3646: It is now easily possible to install a Python framework into your
+  home directory on MacOSX, see Mac/README for more information.

+  tests from compileall.
+
+- Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9.
+
+- Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the private

+  instead.  Also disable caching of powers of 5.
+
+- Issue #6491: Allow --with-dbmliborder to specify that no dbms will be built.
+
+- Issue #6943: Use pkg-config to find the libffi headers when the
+  --with-system-ffi flag is used.
+
+- Issue #7609: Add a --with-system-expat option that causes the system's expat
+  library to be used for the pyexpat module instead of the one included with
+  Python.
+
+- Issue #7589: Only build the nis module when the correct header files are
+  found.
+

+
+- Issue #7449: Skip test_socketserver if threading support is disabled.
+
+- Issue #8672: Add a zlib test ensuring that an incomplete stream can be handled
+  by a decompressor object without errors (it returns incomplete uncompressed
+  data).
+
+- Issue #8533: regrtest uses backslashreplace error handler for stdout to avoid
+  UnicodeEncodeError (write non-ASCII character to stdout using ASCII encoding).
+

+- Issue #7712: test.support gained a new `temp_cwd` context manager which is now
+  also used by regrtest to run all the tests in a temporary directory.  The
+  original CWD is saved in `support.SAVEDCWD`.  Thanks to Florent Xicluna who
+  helped with the patch.
+
+- Issue #7924: Fix an intermittent 'XXX undetected error' failure in test_capi
+  (only seen so far on platforms where the curses module wasn't built), due to
+  an uncleared exception.
+
+- Issue #7728: test_timeout was changed to use support.bind_port instead of a
+  hard coded port.
+
+- Issue #7376: Instead of running a self-test (which was failing) when called
+  with no arguments, doctest.py now gives a usage message.
+
+- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
+
+- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
+  instead of a hardcoded port number in test_rapid_restart.
+
+- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
+  in the Lib/test directory, which might be read-only for the user running the
+  tests.
+
+- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
+  of an option with no handler.
+
+- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
+  fails.  Can be combined with -j.
+
+- Issue #6551: test_zipimport could import and then destroy some modules of the
+  encodings package, which would make other tests fail further down the road
+  because the internally cached encoders and decoders would point to empty
+  global variables.
+
+- Issue #7295: Do not use a hardcoded file name in test_tarfile.
+
+- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
+  primitives such as Lock, RLock, Condition, Event and Semaphore.
+
+- Issue #7248 (part 2): Use a unique temporary directory for importlib source
+  tests instead of tempfile.tempdir. This prevents the tests from sharing state
+  between concurrent executions on the same system.
+
+- Issue #7248: In importlib.test.source.util a try/finally block did not make
+  sure that some referenced objects actually were created in the block before
+  calling methods on the object.
+
+- Issue #7222: Make thread "reaping" more reliable so that reference
+  leak-chasing test runs give sensible results.  The previous method of reaping
+  threads could return successfully while some Thread objects were still
+  referenced.  This also introduces a new private function:
+  ``_thread._count()``.
+
+- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
+  runs the risk of causing the worker thread to fail.
+
+- Issue #7055: test___all__ now greedily detects all modules which have an
+  __all__ attribute, rather than using a hardcoded and incomplete list.
+
+- Issue #7058: Added save/restore for things like sys.argv and cwd to
+  runtest_inner in regrtest, with warnings if the called test modifies them, and
+  a new section in the summary report at the end.
+
+- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
+
+- Fixed tests in importlib.test.source.test_abc_loader that were masking the
+  proper exceptions that should be raised for missing or improper code object
+  bytecode.
+
+- Removed importlib's custom test discovery code and switched to
+  unittest.TestLoader.discover().
+
+Tools/Demos
+-----------
+
+- Issue #5464, #8974: Implement plural forms in msgfmt.py.
+
+- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
+  added to the `Tools/` directory.  They were previously living in the sandbox.
+

+  are always None now.
+
+- Issue #6137: The pickle module now translates module names when loading

+  sharing and migration easier. This behaviour can be disabled using the
+  new `fix_imports` optional argument.
+
+- Removed the ipaddr module.
+
+- Issue #3613: base64.{encode,decode}string are now called

+
+
+What's New in Python 3.1 release candidate 1?
+=============================================
+
+*Release date: 2009-05-30*
+
+Core and Builtins

+- Issue #6012: Add cleanup support to O& argument parsing.
+
+- Issue #6089: Fixed str.format with certain invalid field specifiers
+  that would raise SystemError.
+
+- Issue #5982: staticmethod and classmethod now expose the wrapped
+  function with __func__.
+
+- Added support for multiple context managers in the same with-statement.
+  Deprecated contextlib.nested() which is no longer needed.
+
+- Issue #5829: complex("1e500") no longer raises OverflowError.  This
+  makes it consistent with float("1e500") and interpretation of real
+  and imaginary literals.
+
+- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
+
+- Issue #5994: the marshal module now has docstrings.
+
+- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
+  (1) inf and nan strings with trailing whitespace were incorrectly
+  rejected;  (2) parsing of strings representing infinities and nans
+  was locale aware; and (3) the interpretation of fromhex('-nan')
+  didn't match that of float('-nan').
+
+Library
+-------
+
+- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
+
+- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
+
+- Issue #6121: pydoc now ignores leading and trailing spaces in the
+  argument to the 'help' function.
+
+- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
+  arguments for strings with a space in them.
+
+- collections.namedtuple() was not working with the following field
+  names:  cls, self, tuple, itemgetter, and property.
+
+- In unittest, using a skipping decorator on a class is now equivalent to
+  skipping every test on the class.  The ClassTestSuite class has been removed.
+
+- Issue #6050: Don't fail extracting a directory from a zipfile if
+  the directory already exists.
+
+- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
+  than an int, which makes some operations possible under 64-bit Linux (e.g.
+  DN_MULTISHOT with F_NOTIFY).
+
+- Issue #5761: Add the name of the underlying file to the repr() of various
+  IO objects.
+
+- Issue #5259: smtplib plain auth login no longer gives a traceback.  Fix
+  by Musashi Tamura, tests by Marcin Bachry.
+
+- Issue #1983: Fix functions taking or returning a process identifier to use

+  deepcopy()ing.
+
+- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
+
+- Issue #5918: Fix a crash in the parser module.
+
+- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
+
+- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
+  library. This means, for example, that opening an UTF-16 text file in
+  append mode doesn't add a BOM at the end of the file if the file isn't
+  empty.
+
+- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
+  file is a binary.  Patch by Brodie Rao, tests by Daniel Diniz.  This fix
+  corrects a pydoc regression.
+
+- Issue #5955: aifc's close method did not close the file it wrapped,
+  now it does.  This also means getfp method now returns the real fp.
+
+Installation
+------------
+
+- Issue #6047: fullinstall has been removed because Python 3's executable will
+  now be known as python3.
+
+- Lib/smtpd.py is no longer installed as a script.

+
+Tests
+-----
+
+- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
+  tests on darwin even when the OS was installed on a case-sensitive
+  filesystem. Also fixed tests that should not be run when
+  sys.dont_write_bytecode is true.
+
+
+What's New in Python 3.1 beta 1?
+================================
+
+*Release date: 2009-05-06*
+
+Core and Builtins
+-----------------
+
+- Issue #5914: Add new C API function PyOS_string_to_double, and
+  deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
+
+- Issue #3382: float.__format__, complex.__format__, and %-formatting
+  no longer map 'F' to 'f'. Because of issue #5859 (below), this only
+  affects nan -> NAN and inf -> INF.
+
+- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
+  in all operations, including splitdrive, split, etc.  splitunc() now issues
+  a PendingDeprecation warning.
+
+- Issue #5920: For float.__format__, change the behavior with the
+  empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
+  to be like 'g' but with at least one decimal point and with a
+  default precision of 12. Previously, the behavior the same but with
+  a default precision of 6.  This more closely matches str(), and
+  reduces surprises when adding alignment flags to the empty
+  presentation type. This also affects the new complex.__format__ in
+  the same way.
+
+- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
+
+- Issue #5890: in subclasses of 'property' the __doc__ attribute was
+  shadowed by classtype's, even if it was None.  property now
+  inserts the __doc__ into the subclass instance __dict__.
+
+- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
+  sequences. Patch by Nick Barnes and Victor Stinner.
+
+- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
+
+- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
+  received a new method, detach().  detach() disconnects the underlying stream
+  from the buffer or text IO and returns it.
+
+- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
+  floats with absolute value over 1e50.  Also remove length
+  restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
+  12.34 no longer raise an exception.
+
+- Issue #1588: Add complex.__format__. For example,
+  format(complex(1, 2./3), '.5') now produces a sensible result.
+
+- Issue #5864: Fix empty format code formatting for floats so that it
+  never gives more than the requested number of significant digits.
+
+- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
+  new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
+
+- Issue #5835: Deprecate PyOS_ascii_formatd.
+
+- Issue #4971: Fix titlecase for characters that are their own
+  titlecase, but not their own uppercase.
+
+- Issue #5283: Setting __class__ in __del__ caused a segfault.
+
+- Issue #5816: complex(repr(z)) now recovers z exactly, even when
+  z involves nans, infs or negative zeros.
+
+- Issue #3166: Make int -> float conversions correctly rounded.
+
+- Issue #1869 (and many duplicates): make round(x, n) correctly
+  rounded for a float x, by using the decimal <-> binary conversions
+  from Python/dtoa.c.  As a consequence, (e.g.) round(x, 2) now
+  consistently agrees with format(x, '.2f').
+
+- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
+  some builtin types.
+
+- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
+
+- Issue #5515: str.format() type 'n' combined with commas and leading
+  zeros no longer gives odd results with ints and floats.
+
+- Implement PEP 378, Format Specifier for Thousands Separator, for
+  floats.
+
+- The str function switches to exponential notation at
+  1e11, not 1e12.  This avoids printing 13 significant digits in
+  situations where only 12 of them are correct.  Example problem
+  value: str(1e11 + 0.5).  (This minor issue has existed in 2.x for a
+  long time.)
+
+- Issue #1580: On most platforms, use a 'short' float repr: for a
+  finite float x, repr(x) now outputs a string based on the shortest
+  sequence of decimal digits that rounds to x.  Previous behaviour was
+  to output 17 significant digits and then strip trailing zeros.
+  Another minor difference is that the new repr switches to
+  exponential notation at 1e16 instead of the previous 1e17; this
+  avoids misleading output in some cases.
+
+  There's a new sys attribute sys.float_repr_style, which takes
+  the value 'short' to indicate that we're using short float repr,
+  and 'legacy' if the short float repr isn't available for one
+  reason or another.
+
+  The float repr change involves incorporating David Gay's 'perfect
+  rounding' code into the Python core (it's in Python/dtoa.c).  As a
+  secondary consequence, all string-to-float and float-to-string
+  conversions (including all float formatting operations) will be
+  correctly rounded on these platforms.
+
+  See issue #1580 discussions for details of platforms for which
+  this change does not apply.
+
+- Issue #5759: float() didn't call __float__ on str subclasses.
+
+- The string.maketrans() function is deprecated; there is a new static method
+  maketrans() on the bytes and bytearray classes.  This removes confusion about
+  the types string.maketrans() is supposed to work with, and mirrors the
+  methods available on the str class.
+
+- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
+  its clarity and its speed.
+
+- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
+  to avoid compiler warnings.
+
+- Issue #3739: The unicode-internal encoder now reports the number of characters
+  consumed like any other encoder (instead of the number of bytes).
+
+Installation
+------------
+
+- Issue #5756: Install idle and pydoc with a 3 suffix.
+
+Library
+-------
+
+- Issue #8203: Fix IDLE Credits dialog: view_file() uses its encoding argument.
+
+- Issue #5311: bdist_msi can now build packages that do not depend on a
+  specific Python version.
+
+- Issue #5150: IDLE's format menu now has an option to strip trailing
+  whitespace.
+
+- Issue #5940: distutils.command.build_clib.check_library_list was not doing
+  the right type checkings anymore.
+
+- Issue #4875: On win32, ctypes.util.find_library does no longer
+  return directories.

+  looking for files given by a relative filename.
+
+- Issue #5923: Update the ``turtle`` module to version 1.1, add two new
+  turtle demos in Demo/turtle.
+
+- Issue #5692: In ``zipfile.Zipfile``, fix wrong path calculation when
+  extracting a file to the root directory.
+
+- Issue #5913: os.listdir() should fail for empty path on windows.
+
+- Issue #5084: unpickling now interns the attribute names of pickled objects,
+  saving memory and avoiding growth in size of subsequent pickles. Proposal
+  and original patch by Jake McGuire.
+
+- The json module now works exclusively with str and not bytes.
+
+- Issue #3959: The ipaddr module has been added to the standard library.
+  Contributed by Google.
+
+- Issue #3002: ``shutil.copyfile()`` and ``shutil.copytree()`` now raise an
+  error when a named pipe is encountered, rather than blocking infinitely.
+
+- Issue #5857: tokenize.tokenize() now returns named tuples.
+
+- Issue #4305: ctypes should now build again on mipsel-linux-gnu
+
+- Issue #1734234: Massively speedup ``unicodedata.normalize()`` when the
+  string is already in normalized form, by performing a quick check beforehand.
+  Original patch by Rauli Ruohonen.
+
+- Issue #5853: calling a function of the mimetypes module from several threads
+  at once could hit the recursion limit if the mimetypes database hadn't been
+  initialized before.
+
+- Issue #5854: Updated __all__ to include some missing names and remove some
+  names which should not be exported.
+
+- Issue #3102:  All global symbols that the _ctypes extension defines
+  are now prefixed with 'Py' or '_ctypes'.
+
+- Issue #5041: ctypes does now allow pickling wide character.
+
+- Issue #5812: For the two-argument form of the Fraction constructor,
+  Fraction(m, n), m and n are permitted to be arbitrary Rational
+  instances.
+
+- Issue #5812: Fraction('1e6') is valid: more generally, any string
+  that's valid for float() is now valid for Fraction(), with the
+  exception of strings representing NaNs and infinities.
+
+- Issue #5734: BufferedRWPair was poorly tested and had several glaring
+  bugs. Patch by Brian Quinlan.
+
+- Issue #1161031: fix readwrite select flag handling: POLLPRI now
+  results in a handle_expt_event call, not handle_read_event, and POLLERR
+  and POLLNVAL now call handle_close, not handle_expt_event.  Also,
+  dispatcher now has an 'ignore_log_types' attribute for suppressing
+  log messages, which is set to 'warning' by default.
+
+- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
+  new arguments introduced in 2.5.
+
+- Issue #5828 (Invalid behavior of unicode.lower): Fixed bogus logic in
+  makeunicodedata.py and regenerated the Unicode database (This fixes
+  u'\u1d79'.lower() == '\x00').
+
+Extension Modules
+-----------------
+
+- Issue #5881: Remove old undocumented compatibility interfaces in hashlib and
+  pwd.
+
+- Issue #5463: In struct module, remove deprecated float coercion
+  for integer type codes: struct.pack('L', 0.3) should now raise
+  an error.  The _PY_STRUCT_FLOAT_COERCE constant has been removed.
+  The version number has been bumped to 0.3.
+
+- Issue #5359: Readd the Berkeley DB detection code to allow _dbm be built
+  using Berkeley DB.
+
+Tests
+-----
+
+- Issue #5354: New test support function import_fresh_module() makes
+  it easy to import both normal and optimised versions of modules.
+  test_heapq and test_warnings have been adjusted to use it, tests for
+  other modules with both C and Python implementations in the stdlib
+  can be adjusted to use it over time.
+
+- Issue #5837: Certain sequences of calls to set() and unset() for
+  support.EnvironmentVarGuard objects restored the environment variables

+
+
+What's New in Python 3.1 alpha 2?
+=================================
+
+*Release date: 2009-4-4*
+
+Core and Builtins
+-----------------
+
+- Implement PEP 378, Format Specifier for Thousands Separator, for
+  integers.
+
+- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
+
+- Issue #5499: The 'c' code for argument parsing functions now only accepts a
+  byte, and the 'C' code only accepts a unicode character.
+
+- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
+  when hitting the recursion limit under certain circumstances.
+
+- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
+
+- Fix a segfault when running test_exceptions with coverage, caused by
+  insufficient checks in accessors of Exception.__context__.
+
+- Issue #5604: non-ASCII characters in module name passed to
+  imp.find_module() were converted to UTF-8 while the path is
+  converted to the default filesystem encoding, causing nonsense.
+
+- Issue #5126: str.isprintable() returned False for space characters.
+
+- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
+  the end sys.path, for compatibility with the system install of Python.
+
+- Issue #4688: Add a heuristic so that tuples and dicts containing only
+  untrackable objects are not tracked by the garbage collector. This can
+  reduce the size of collections and therefore the garbage collection overhead
+  on long-running programs, depending on their particular use of datatypes.
+
+- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
+  improve its performance.  Long divisions and remainder operations
+  are now between 50% and 150% faster.
+
+- Issue #4258: Make it possible to use base 2**30 instead of base
+  2**15 for the internal representation of integers, for performance
+  reasons.  Base 2**30 is enabled by default on 64-bit machines.  Add
+  --enable-big-digits option to configure, which overrides the
+  default.  Add sys.int_info structseq to provide information about
+  the internal format.
+
+- Issue #4474: PyUnicode_FromWideChar now converts characters outside
+  the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
+  and sizeof(Py_UNICODE) == 2.
+
+- Issue #5237: Allow auto-numbered fields in str.format(). For
+  example: '{} {}'.format(1, 2) == '1 2'.
+
+- Issue #5392: when a very low recursion limit was set, the interpreter would
+  abort with a fatal error after the recursion limit was hit twice.
+
+- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
+  short file names.
+
+Library
+-------
+
+- Issue #2625: added missing items() call to the for loop in
+  mailbox.MH.get_message().
+

+
+
+What's New in Python 3.1 alpha 1
+================================
+
+*Release date: 2009-03-07*
+
+Core and Builtins
+-----------------
+
+- The io module has been reimplemented in C for speed.
+
+- Give dict views an informative __repr__.
+
+- Issue #5247: Improve error message when unknown format codes are
+  used when using str.format() with str, int, and float arguments.
+
+- Issue #5249: time.strftime returned malformed string when format string
+  contained non ascii character on windows.
+
+- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
+  source has already been decoded into str.
+
+- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
+  rotating the object pointer by 4 bits to the right.
+
+- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
+  it now forces its argument to double before testing for infinity.
+
+- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
+  returns a non-number type.
+
+- Issue #5182: Removed memoryview.__str__.
+
+- Issue #1717: Removed builtin cmp() function, dropped tp_compare
+  slot, the C API functions PyObject_Compare and PyUnicode_Compare and
+  the type definition cmpfunc.  The tp_compare slot has been renamed
+  to tp_reserved, and is reserved for future usage.
+
+- Issue #1242657: the __len__() and __length_hint__() calls in several tools
+  were suppressing all exceptions.  These include list() and bytearray().
+
+- Issue #4707: round(x, n) now returns an integer if x is an integer.
+  Previously it returned a float.
+
+- Issue #4753: By enabling a configure option named '--with-computed-gotos'
+  on compilers that support it (notably: gcc, SunPro, icc), the bytecode
+  evaluation loop is compiled with a new dispatch mechanism which gives
+  speedups of up to 20%, depending on the system, on various benchmarks.
+
+- Issue #4874: Most builtin decoders now reject unicode input.
+
+- Issue #4842: Don't allow trailing 'L' when constructing an integer
+  from a string.
+
+- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
+
+- Issue #4838: When a module is deallocated, free the memory backing the
+  optional module state data.
+
+- Issue #4910: Rename nb_long slot to nb_reserved, and change its
+  type to ``(void *)``.
+
+- Issue #4935: The overflow checking code in the expandtabs() method common
+  to str, bytes and bytearray could be optimized away by the compiler, letting
+  the interpreter segfault instead of raising an error.
+
+- Issue #3720: Fix a crash when an iterator modifies its class and removes its
+  __next__ method.
+
+- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
+  function no longer attempt to call the __long__ slot to convert an object
+  to an integer.  Only the __int__ and __trunc__ slots are examined.
+
+- Issue #4893: Use NT threading on CE.
+
+- Issue #4915: Port sysmodule to Windows CE.
+
+- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
+  common cases are optimized thanks to a dedicated fast path and a moderate
+  amount of loop unrolling.
+
+- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
+  collecting the oldest generation) so that allocating lots of objects without
+  destroying them does not show quadratic performance. Based on a proposal by
+  Martin von Löwis at
+  http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
+
+- Issue #4604: Some objects of the I/O library could still be used after
+  having been closed (for instance, a read() call could return some
+  previously buffered data). Patch by Dmitry Vasiliev.
+
+- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
+  flag to work properly. Furthermore, when specifying -u, the text stdout
+  and stderr streams have line-by-line buffering enabled (the default being
+  to buffer arbitrary chunks of data).
+
+- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
+  instead of ints (reducing its size from 4 to 8 times thereby reducing
+  Python's overall memory).
+
+- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
+  an existing .py counterpart, override the co_filename attributes of all
+  code objects if the original filename is obsolete (which can happen if the
+  file has been renamed, moved, or if it is accessed through different paths).
+  Patch by Ziga Seilnacht and Jean-Paul Calderone.
+
+- Issue #4580: Fix slicing of memoryviews when the item size is greater than
+  one byte. Also fixes the meaning of len() so that it returns the number of
+  items, rather than the size in bytes.
+
+- Issue #4075: Use OutputDebugStringW in Py_FatalError.
+
+- Issue #4747: When the terminal does not use utf-8, executing a script with
+  non-ascii characters in its name could fail with a "SyntaxError: None" error.
+
+- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
+  to open file with a bytes filename on Windows.
+
+- Issue #3680: Reference cycles created through a dict, set or deque iterator
+  did not get collected.
+
+- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
+  where the tp_hash and tp_dict slots are both NULL.
+
+- Issue #4759: None is now allowed as the first argument of
+  bytearray.translate().  It was always allowed for bytes.translate().
+
+- Added test case to ensure attempts to read from a file opened for writing
+  fail.
+
+- Issue #3106: Speedup some comparisons (str/str and int/int).
+
+- Issue #2183: Simplify and optimize bytecode for list, dict and set
+  comprehensions. Original patch for list comprehensions by Neal Norwitz.
+
+- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
+  print elapsed times, not only when some objects are uncollectable /
+  unreachable. Original patch by Neil Schemenauer.
+
+- Issue #3439: Add a bit_length method to int.
+
+- Issue #2173: When getting device encoding, check that return value of
+  nl_langinfo is not the empty string.  This was causing silent build
+  failures on OS X.
+
+- Issue #4597: Fixed several opcodes that weren't always propagating
+  exceptions.
+
+- Issue #4589: Fixed exception handling when the __exit__ function of a
+  context manager returns a value that cannot be converted to a bool.
+
+- Issue #4445: Replace "sizeof(PyBytesObject)" with
+  "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
+  bytes instances.  On a typical machine this saves 3 bytes of memory
+  (on average) per allocation of a bytes instance.
+
+- Issue #4533: File read operation was dreadfully slow due to a slowly
+  growing read buffer. Fixed by using the same growth rate algorithm as
+  Python 2.x.
+
+- Issue #4509: Various issues surrounding resize of bytearray objects to
+  which there are buffer exports (e.g. memoryview instances).
+
+- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
+  method on file objects with closefd=False. The file descriptor is still
+  kept open but the file object behaves like a closed file. The ``FileIO``
+  object also got a new readonly attribute ``closefd``.
+
+- Issue #4569: Interpreter crash when mutating a memoryview with an item size
+  larger than 1.
+
+- Issue #4748: Lambda generators no longer return a value.
+
+- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
+
+- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
+  PyUnicode_DecodeUTF8() once, remember the result and output it in a second
+  step. This avoids problems with counting UTF-8 bytes that ignores the effect
+  of using the replace error handler in PyUnicode_DecodeUTF8().
+

+  be disabled, and not compiled.
+
+- Issue #5008: When a file is opened in append mode with the new IO library,
+  do an explicit seek to the end of file (so that e.g. tell() returns the
+  file size rather than 0). This is consistent with the behaviour of the
+  traditional 2.x file object.
+
+- Issue #5013: Fixed a bug in FileHandler which occurred when the delay
+  parameter was set.
+
+- Issue #4842: Always append a trailing 'L' when pickling longs using

+- Issue #4796: Added Decimal.from_float() and Context.create_decimal_from_float()
+  to the decimal module.
+
+- Fractions.from_float() no longer loses precision for integers too big to
+  cast as floats.
+
+- Issue #4812: add missing underscore prefix to some internal-use-only
+  constants in the decimal module.  (Dec_0 becomes _Dec_0, etc.)
+
+- Issue #4790: The nsmallest() and nlargest() functions in the heapq module
+  did unnecessary work in the common case where no key function was specified.
+
+- Issue #4795: inspect.isgeneratorfunction() returns False instead of None when
+  the function is not a generator.
+
+- Issue #4702: Throwing a DistutilsPlatformError instead of IOError in case
+  no MSVC compiler is found under Windows. Original patch by Philip Jenvey.
+
+- Issue #4646: distutils was choking on empty options arg in the setup
+  function. Original patch by Thomas Heller.
+

+
+- Issue #3248: Allow placing ScrolledText in a PanedWindow.
+

+- Issue #4739: Add pydoc help topics for symbols, so that e.g. help('@')
+  works as expected in the interactive environment.
+
+- Issue #4756: zipfile.is_zipfile() now supports file-like objects. Patch by
+  Gabriel Genellina.
+
+- Issue #4574: reading an UTF16-encoded text file crashes if \r on 64-char
+  boundary.
+
+- Issue #4223: inspect.getsource() will now correctly display source code
+  for packages loaded via zipimport (or any other conformant PEP 302
+  loader). Original patch by Alexander Belopolsky.
+
+- Issue #4201: pdb can now access and display source code loaded via
+  zipimport (or any other conformant PEP 302 loader). Original patch by
+  Alexander Belopolsky.
+
+- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
+  302 conformant loader) will now work correctly in most cases (they
+  are still subject to the constraints that exist for all code running
+  from inside a module loaded via a PEP 302 loader and attempting to
+  perform IO operations based on __file__). Original patch by
+  Alexander Belopolsky.
+
+- Issues #4082 and #4512: Add runpy support to zipimport in a manner that

+
+- Issue #4483: _dbm module now builds on systems with gdbm & gdbm_compat

+
+- Issue #1055234: cgi.parse_header(): Fixed parsing of header parameters to
+  support unusual filenames (such as those containing semi-colons) in
+  Content-Disposition headers.
+
+- Issue #4384: Added logging integration with warnings module using
+  captureWarnings(). This change includes a NullHandler which does nothing;

+  doesn't configure logging.
+
+- Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an
+  exception.

+
+- Added the subprocess.check_output() convenience function to get output

+  support unusual filenames (such as those containing semi-colons) in
+  Content-Disposition headers.
+
+- Issue #4861: ctypes.util.find_library(): Robustify. Fix library detection on
+  biarch systems. Try to rely on ldconfig only, without using objdump and gcc.
+
+- Issue #5104: The socket module now raises OverflowError when 16-bit port and
+  protocol numbers are supplied outside the allowed 0-65536 range on bind()
+  and getservbyport().
+
+- Windows locale mapping updated to Vista.
+

+Extension Modules
+-----------------
+
+- Issue #3745: Fix hashlib to always reject unicode and non buffer-api
+  supporting objects as input no matter how it was compiled (built in
+  implementations or external openssl library).
+
+- Issue #4397: Fix occasional test_socket failure on OS X.
+
+- Issue #4279: Fix build of parsermodule under Cygwin.
+
+- Issue #4751: hashlib now releases the GIL when hashing large buffers
+  (with a hardwired threshold of 2048 bytes), allowing better parallelization
+  on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
+
+- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
+
+- Issue #4738: Each zlib object now has a separate lock, allowing to compress
+  or decompress several streams at once on multi-CPU systems. Also, the GIL
+  is now released when computing the CRC of a large buffer. Patch by ebfe.
+
+- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.
+
+- Issue #1040026: Fix os.times result on systems where HZ is incorrect.
+
+- Issues #3167, #3682: Fix test_math failures for log, log10 on Solaris,
+  OpenBSD.
+
+- Issue #4583: array.array would not always prohibit resizing when a buffer
+  has been exported, resulting in an interpreter crash when accessing the
+  buffer.

+
+Tests

+  regression tests in parallel, shortening the total runtime.
+
+- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
+  Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
+  the same behaviour as test_ttkguionly (and now also test_tk) which is to
+  skip the tests if DISPLAY is defined but can't be used.
+
+- regrtest no longer treats ImportError as equivalent to SkipTest.  Imports
+  that should cause a test to be skipped are now done using import_module
+  from test support, which does the conversion.
+
+- Issue #5083: New 'gui' resource for regrtest.
