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.
-
-- Issue #17043: The unicode-internal decoder no longer read past the end of
- 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"

-
-- Issue #11461: Fix the incremental UTF-16 decoder. Original patch by
- Amaury Forgeot d'Arc.

-- Issue #16367: Fix FileIO.readall() on Windows for files larger than 2 GB.
-
-- 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
- when retrieving a REG_DWORD value. This corrects functions like
- 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
-

- user that created them, even when the source file is read-only.
-
-- Issue #14783: Improve int() docstring and switch docstrings for str(),
- range(), and slice() to use multi-line signatures.
-
-- Issue #15379: Fix passing of non-BMP characters as integers for the charmap
- decoder (already working as unicode strings). Patch by Serhiy Storchaka.
-
-- Issue #13992: The trashcan mechanism is now thread-safe. This eliminates
- sporadic crashes in multi-thread programs when several long deallocator
- chains ran concurrently and involved subclasses of built-in container
- types.
-
-- Issue #15846: Fix SystemError which happened when using ast.parse in an
- exception handler on code with syntax errors.
-
-- Issue #15761: Fix crash when PYTHONEXECUTABLE is set on Mac OS X.
-
-- Issue #15801: Make sure mappings passed to '%' formatting are actually
- subscriptable.
+- Issue #18960: The first line of Python script could be executed twice when
+ the source encoding was specified on the second line. Now the source encoding
+ declaration on the second line isn't effective if the first line contains

+ source encoding declarations, and can be used to make Python batch files
+ on Windows.

-- Issue #14579: Fix CVE-2012-2135: vulnerability in the utf-16 decoder after
- error handling. Patch by Serhiy Storchaka.
+- Issue #14432: Generator now clears the borrowed reference to the thread
+ state. Fix a crash when a generator is created in a C thread that is
+ destroyed while the generator is still used. The issue was that a generator
+ contains a frame, and the frame kept a reference to the Python state of the
+ destroyed C thread. The crash occurs when a trace function is setup.

+ module, rather than silently let them emit clear text data.
-- Issue #13889: Check and (if necessary) set FPU control word before calling
- any of the dtoa.c string <-> float conversion functions, on MSVC builds of
- Python. This fixes issues when embedding Python in a Delphi app.

- 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 3.2.2?
-===========================
-
-*Release date: 03-Sep-2011*
-
-Core and Builtins
------------------
-
-- Issue #12326: sys.platform is now always 'linux2' on Linux, even if Python
- is compiled on Linux 3.
-
-- Accept bytes for the AST string type. This is temporary until a proper fix in
- 3.3.
-
-Library
--------
-
-- Issue #8286: The distutils command sdist will print a warning message instead
- of crashing when an invalid path is given in the manifest template.
-
-- Issue #12841: tarfile unnecessarily checked the existence of numerical user
- and group ids on extraction. If one of them did not exist the respective id
- of the current user (i.e. root) was used for the file and ownership
- information was lost.
-
-- Issue #10946: The distutils commands bdist_dumb, bdist_wininst and bdist_msi
- now respect a --skip-build option given to bdist.
-
-- Issue #12839: Fix crash in zlib module due to version mismatch.

-
-*Release date: 14-Aug-2011*
-
-Core and Builtins
------------------
-
-- Issue #12732: In narrow unicode builds, allow Unicode identifiers which fall
- outside the BMP.
-
-- Issue #11603: Fix a crash when __str__ is rebound as __repr__. Patch by
- Andreas Stührk.
+- Issue #17200: telnetlib's read_until and expect timeout was broken by the
+ fix to Issue #14635 in Python 3.3.0 to be interpreted as milliseconds
+ instead of seconds when the platform supports select.poll (ie: everywhere).
+ It is now treated as seconds once again.
-- Issue #11321: Fix a crash with multiple imports of the _pickle module when
- embedding Python. Patch by Andreas Stührk.
+- Issue #17429: platform.linux_distribution() now decodes files from the UTF-8
+ encoding with the surrogateescape error handler, instead of decoding from the
+ locale encoding in strict mode. It fixes the function on Fedora 19 which is
+ probably the first major distribution release with a non-ASCII name. Patch
+ written by Toshio Kuratomi.
-- Verify the types of AST strings and identifiers provided by the user before
- compiling them.
+- Issue #19929: Call os.read with 32768 within subprocess.Popen.communicate

- and its type get caught in a reference cycle, and the instance's
- deallocator calls one of the methods on the type (e.g. when subclassing
- IOBase). Diagnosis and patch by Davide Rizzo.
+- Issue #19138: doctest's IGNORE_EXCEPTION_DETAIL now allows a match when
+ no exception detail exists (no colon following the exception's name, or
+ a colon does follow but no text follows the colon).
-- When a generator yields, do not retain the caller's exception state on the
- generator.
+- Issue #19834: Support unpickling of exceptions pickled by Python 2.
-- Issue #12475: Prevent generators from leaking their exception state into the
