 -  * Backport 3.3.0 fixes to 3.2 branch (for release in 3.2.4)
 -  * Since Xcode 4 removes ppc support, extension module builds now
 -    check for ppc compiler support and by default remove ppc and
 -    ppc64 archs when they are not available.
 -  * Extension module builds now revert to using system installed
 -    headers and libs (/usr and /System/Library) if the SDK used
 -    to build the interpreter is not installed or has moved.
 -  * Try to avoid building extension modules with deprecated
 -    and problematic Apple llvm-gcc compiler.  If original compiler
 -    is not available, use clang instead by default.

 -- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
 -  Distutils-based packages with C extension modules may fail because
 -  Apple has removed gcc-4.2, the version used to build python.org
 -  64-bit/32-bit Pythons.  If the user does not explicitly override
 -  the default C compiler by setting the CC environment variable,
 -  Distutils will now attempt to compile extension modules with clang
 -  if gcc-4.2 is required but not found. Also as a convenience, if
 -  the user does explicitly set CC, substitute its value as the default
 -  compiler in the Distutils LDSHARED configuration variable for OS X.
 -  (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
 -  SDK, neither of which are available in Xcode 4.  This change does not
 -  attempt to override settings to support their use with Xcode 4.)

 -- Issue #9670: Increase the default stack size for secondary threads on Mac OS X
 -  and FreeBSD to reduce the chances of a crash instead of a "maximum recursion
 -  depth" RuntimeError exception (patch by Ronald Oussoren).

 -  environment after Distutils set it.  Instead, have Distutils set 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.
 -

 -  to be able to unload the module.
 -
 -- Issue #12065: connect_ex() on an SSL socket now returns the original errno
 -  when the socket's timeout expires (it used to return None).

 -
 -- Issue #10898: Allow compiling the posix module when the C library defines
 -  a symbol named FSTAT.
 -
 -- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)

 -  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

 -What's New in Python 3.2 Release Candidate 1
 -============================================
 -
 -*Release date: 16-Jan-2011*
 -
 -Core and Builtins
 ------------------
 -
 -- Issue #10889: range indexing and slicing now works correctly on ranges with
 -  a length that exceeds sys.maxsize.
 -
 -- Issue #10892: Don't segfault when trying to delete __abstractmethods__ from a
 -  class.
 -
 -- Issue #8020: Avoid a crash where the small objects allocator would read
 -  non-Python managed memory while it is being modified by another thread.  Patch
 -  by Matt Bandy.
 -
 -- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
 -  io.FileIO objects (to not translate newlines, \r\n <=> \n).  The Python parser
 -  translates newlines (\r\n => \n).
 -
 -- 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
 -  (length bigger than 2^31-1 bytes).
 -
 -- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
 -  stdprinter.write() clamp the length to INT_MAX on Windows.
 -
 -- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()
 -  can now handle dates after 2038.
 -
 -- Issue #10780: PyErr_SetFromWindowsErrWithFilename() and
 -  PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
 -  filesystem encoding instead of UTF-8.
 -
 -- Issue #10779: PyErr_WarnExplicit() decodes the filename from the filesystem
 -  encoding instead of UTF-8.
 -
 -- Add sys.flags attribute for the new -q command-line option.
 -
 -- Issue #11506: Trying to assign to a bytes literal should result in a
 -  SyntaxError.
 -
 -Library
 --------
 -
 -- 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 #10684: shutil.move used to delete a folder on case insensitive
 -  filesystems when the source and destination name where the same except
 -  for the case.
 -
 -- 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.
 -
 -- Issue #10875: Update Regular Expression HOWTO; patch by 'SilentGhost'.
 -
 -- Issue #10872: The repr() of TextIOWrapper objects now includes the mode
 -  if available.
 -
 -- Issue #10869: Fixed bug where ast.increment_lineno modified the root node
 -  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 #10730: Add SVG mime types to mimetypes module.
 -

 -- 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 '+'.

 -- Issue #10499: configparser supports pluggable interpolation handlers. The
 -  default classic interpolation handler is called BasicInterpolation. Another
 -  interpolation handler added (ExtendedInterpolation) which supports the syntax
 -  used by zc.buildout (e.g. interpolation between sections).
 -
 -- configparser: the SafeConfigParser class has been renamed to ConfigParser.
 -  The legacy ConfigParser class has been removed but its interpolation mechanism
 -  is still available as LegacyInterpolation.
 -
 -- configparser: Usage of RawConfigParser is now discouraged for new projects
 -  in favor of ConfigParser(interpolation=None).

 -- Issue #9421: configparser's getint(), getfloat() and getboolean() methods
 -  accept vars and default arguments just like get() does.
 -
 -- Issue #9452: configparser supports reading from strings and dictionaries
 -  (thanks to the mapping protocol API, the latter can be used to copy data
 -  between parsers).
 -
 -- configparser: accepted INI file structure is now customizable, including
 -  comment prefixes, name of the DEFAULT section, empty lines in multiline
 -  values, and indentation.
