-=====================================
-==> Release 1.3 (13 October 1995) <==
-=====================================
+======================================
+==> Release 1.4 (sometime 3Q 1996) <==
+======================================
-Major change
-============
+XXX This file still has to be updated!
-Two words: Keyword Arguments. See the first section of Chapter 12 of
-the Tutorial.
+Some highlights:
-(The rest of this file is textually the same as the remaining sections
-of that chapter.)
+- "make install" overhaul to install everything and use a version number
+- new builtin modules operator, errno
-Changes to the WWW and Internet tools
-=====================================
+- changes needed by Numeric Python extensions:
-The "htmllib" module has been rewritten in an incompatible fashion.
-The new version is considerably more complete (HTML 2.0 except forms,
-but including all ISO-8859-1 entity definitions), and easy to use.
-Small changes to "sgmllib" have also been made, to better match the
-tokenization of HTML as recognized by other web tools.
+ - x[lo:hi:stride]
+ - x[a, b, c]
+ - x[a, ..., z]
-A new module "formatter" has been added, for use with the new
-"htmllib" module.
+ plus "ellipses" and "slice" objects
-The "urllib"and "httplib" modules have been changed somewhat to allow
-overriding unknown URL types and to support authentication. They now
-use "mimetools.Message" instead of "rfc822.Message" to parse headers.
-The "endrequest()" method has been removed from the HTTP class since
-it breaks the interaction with some servers.
-
-The "rfc822.Message" class has been changed to allow a flag to be
-passed in that says that the file is unseekable.
-
-The "ftplib" module has been fixed to be (hopefully) more robust on
-Linux.
-
-Several new operations that are optionally supported by servers have
-been added to "nntplib": "xover", "xgtitle", "xpath" and "date".
-
-Other Language Changes
-======================
-
-The "raise" statement now takes an optional argument which specifies
-the traceback to be used when printing the exception's stack trace.
-This must be a traceback object, such as found in "sys.exc_traceback".
-When omitted or given as "None", the old behavior (to generate a stack
-trace entry for the current stack frame) is used.
-
-The tokenizer is now more tolerant of alien whitespace. Control-L in
-the leading whitespace of a line resets the column number to zero,
-while Control-R just before the end of the line is ignored.
-
-Changes to Built-in Operations
-==============================
-
-For file objects, "f.read(0)" and "f.readline(0)" now return an empty
-string rather than reading an unlimited number of bytes. For the
-latter, omit the argument altogether or pass a negative value.
-
-A new system variable, "sys.platform", has been added. It specifies
-the current platform, e.g. "sunos5" or "linux1".
-
-The built-in functions "input()" and "raw_input()" now use the GNU
-readline library when it has been configured (formerly, only
-interactive input to the interpreter itself was read using GNU
-readline). The GNU readline library provides elaborate line editing
-and history. The Python debugger ("pdb") is the first beneficiary of
-this change.
-
-Two new built-in functions, "globals()" and "locals()", provide access
-to dictionaries containming current global and local variables,
-respectively. (These augment rather than replace "vars()", which
-returns the current local variables when called without an argument,
-and a module's global variables when called with an argument of type
-module.)
-
-The built-in function "compile()" now takes a third possible value for
-the kind of code to be compiled: specifying "'single'" generates code
-for a single interactive statement, which prints the output of
-expression statements that evaluate to something else than "None".
-
-Library Changes
-===============
-
-There are new module "ni" and "ihooks" that support importing modules
-with hierarchical names such as "A.B.C". This is enabled by writing
-"import ni; ni.ni()" at the very top of the main program. These
-modules are amply documented in the Python source.
-
-The module "rexec" has been rewritten (incompatibly) to define a class
-and to use "ihooks".
-
-The "string.split()" and "string.splitfields()" functions are now the
-same function (the presence or absence of the second argument
-determines which operation is invoked); similar for "string.join()"
-and "string.joinfields()".
-
-The "Tkinter" module and its helper "Dialog" have been revamped to use
-keyword arguments. Tk 4.0 is now the standard. A new module
-"FileDialog" has been added which implements standard file selection
-dialogs.
-
-The optional built-in modules "dbm" and "gdbm" are more coordinated
---- their "open()" functions now take the same values for their "flag"
-argument, and the "flag" and "mode" argument have default values (to
-open the database for reading only, and to create the database with
-mode "0666" minuse the umask, respectively). The memory leaks have
-finally been fixed.
-
-A new dbm-like module, "bsddb", has been added, which uses the BSD DB
-package's hash method.
-
-A portable (though slow) dbm-clone, implemented in Python, has been
-added for systems where none of the above is provided. It is aptly
-dubbed "dumbdbm".
-
-The module "anydbm" provides a unified interface to "bsddb", "gdbm",
-"dbm", and "dumbdbm", choosing the first one available.
-
-A new extension module, "binascii", provides a variety of operations
-for conversion of text-encoded binary data.
-
-There are three new or rewritten companion modules implemented in
-Python that can encode and decode the most common such formats: "uu"
-(uuencode), "base64" and "binhex".
-
-A module to handle the MIME encoding quoted-printable has also been
-added: "quopri".
-
-The parser module (which provides an interface to the Python parser's
-abstract syntax trees) has been rewritten (incompatibly) by Fred
-Drake. It now lets you change the parse tree and compile the result!
-
-The \code{syslog} module has been upgraded and documented.
-
-Other Changes
-=============
-
-The dynamic module loader recognizes the fact that different filenames
-point to the same shared library and loads the library only once, so
-you can have a single shared library that defines multiple modules.
-(SunOS / SVR4 style shared libraries only.)
-
-Jim Fulton's ``abstract object interface'' has been incorporated into
-the run-time API. For more detailes, read the files
-"Include/abstract.h" and "Objects/abstract.c".
-
-The Macintosh version is much more robust now.
-
-Numerous things I have forgotten or that are so obscure no-one will
-notice them anyway :-)
