    All protocols tested against all other protocols.

  Patch # 1140 (my code, approved by Effbot).

  Make sure the type of the return value of re.sub(x, y, z) is the type
  of y+x (i.e. unicode if either is unicode, str if they are both str)
  even if there are no substitutions or if x==z (which triggered various
  special cases in join_list()).

  Could be backported to 2.5; no need to port to 3.0.

  Patch # 1026 by Benjamin Aranguren (with Alex Martelli):
  Backport abc.py and isinstance/issubclass overloading to 2.6.

  I had to backport test_typechecks.py myself, and make one small change
  to abc.py to avoid duplicate work when x.__class__ and type(x) are the
  same.

  Generators had their throw() method allowing string exceptions.  That's a
  no-no.

  Fixes issue #1147.  Need to fix 2.5 to raise a proper warning if a string
  exception is passed in.

  Replaced variable o with obj in operator.rst because o is easy to
  confuse.

  Added a note about Python 3's collections.Mapping etc., above section
  that describes isMappingType() etc.

  Added xrefs between os, os.path, fileinput, and open().

  Merged the decimal-branch (revisions 54886 to 58140). Decimal is now
  fully updated to the latests Decimal Specification (v1.66) and the
  latests test cases (v2.56).

  Thanks to Mark Dickinson for all his help during this process.

  Put the parameter watchexp back in (changed watchexp from an int
  to a bool).  Also second argument to watchexp is now converted
  to Decimal, just as with all the other two-argument operations.

  Thanks Mark Dickinson.

  Add support for asyncore server-side SSL support.  This requires
  adding the 'makefile' method to ssl.SSLSocket, and importing the
  requisite fakefile class from socket.py, and making the appropriate
  changes to it to make it use the SSL connection.

  Added sample HTTPS server to test_ssl.py, and test that uses it.

  Change SSL tests to use https://svn.python.org/, instead of
  www.sf.net and pop.gmail.com.

  Added utility function to ssl module, get_server_certificate,
  to wrap up the several things to be done to pull a certificate
  from a remote server.

  Sync-up named tuples with the latest version of the ASPN recipe.
