Core and Builtins
-----------------
-- Issue #1692335: Move initial args assignment to
- BaseException.__new__ to help pickling of naive subclasses.
-
-- Issue #17275: Corrected class name in init error messages of the C version of
- BufferedWriter and BufferedRandom.
-
-- Issue #7963: Fixed misleading error message that issued when object is
- called without arguments.
-
-- Issue #5308: Raise ValueError when marshalling too large object (a sequence
- with size >= 2**31), instead of producing illegal marshal data.
-
-- Issue #12983: Bytes literals with invalid \x escape now raise a SyntaxError
- and a full traceback including line number.
-
-- Issue #17173: Remove uses of locale-dependent C functions (isalpha() etc.)
- in the interpreter.

- input buffer.
-
-- Issue #16979: Fix error handling bugs in the unicode-escape-decode decoder.
-
-- Issue #10156: In the interpreter's initialization phase, unicode globals
- are now initialized dynamically as needed.
-
-- Issue #16975: Fix error handling bug in the escape-decode bytes decoder.
-
-- Issue #14850: Now a charmap decoder treats U+FFFE as "undefined mapping"

- Amaury Forgeot d'Arc.

-
-- Issue #16455: On FreeBSD and Solaris, if the locale is C, the
- ASCII/surrogateescape codec is now used, instead of the locale encoding, to
- decode the command line arguments. This change fixes inconsistencies with
- os.fsencode() and os.fsdecode() because these operating systems announces an
- ASCII locale encoding, whereas the ISO-8859-1 encoding is used in practice.
-
-- Issue #16761: Calling int() with base argument only now raises TypeError.
-
-- Issue #16759: Support the full DWORD (unsigned long) range in Reg2Py

- winreg.QueryValueEx that may have been returning truncated values.
-
-- Issue #14420: Support the full DWORD (unsigned long) range in Py2Reg
- when passed a REG_DWORD value. Fixes OverflowError in winreg.SetValueEx.

- its refcount had dropped to zero.
-
-- Issue #16416: On Mac OS X, operating system data are now always
- encoded/decoded to/from UTF-8/surrogateescape, instead of the locale encoding
- (which may be ASCII if no locale environment variable is set), to avoid
- inconsistencies with os.fsencode() and os.fsdecode() functions which are
- already using UTF-8/surrogateescape.
-
-- Issue #16588: Silence unused-but-set warnings in Python/thread_pthread.h

- 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.)

-What's New in Python 3.2.1 release candidate 2?
-===============================================
-
-*Release date: 03-Jul-2011*
-
-Core and Builtins

- and FreeBSD to reduce the chances of a crash instead of a "maximum recursion
- depth" RuntimeError exception (patch by Ronald Oussoren).

- the garbage collector while the Heap lock is held.
-
-- Issue #12451: The XInclude default loader of xml.etree now decodes files from

- to avoid encoding issues.

-
-- 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
- 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.

- their encode() method anymore, but continue to call the reset() method if the
- final argument is True.

-
-- Correct lookup of __dir__ on objects. Among other things, this causes errors
- besides AttributeError found on lookup to be propagated.

-- Issue #12124: zipimport doesn't keep a reference to zlib.decompress() anymore
- 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).

-
-Build
------
-
-- Issue #8746: Correct faulty configure checks so that os.chflags() and

- (*BSD and OS X). Also add new stat file flags for OS X (UF_HIDDEN and
- UF_COMPRESSED).
-
-- Issue #11217: For 64-bit/32-bit Mac OS X universal framework builds, ensure
