-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.
-

-
-- 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

- ``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.

- method send_message to send an email.message.Message object.
-

- 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 #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.
