-What's New in Python 2.6.6 rc 1?
-================================
+- 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.)
-*Release date: 2010-08-03*
+- Issue #9021: Add an introduction to the copy module documentation.
-Core and Builtins
------------------
+- Issue #6005: Examples in the socket library documentation use sendall, where
+ relevant, instead send method.
-- Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and
- utf-16 incremental encoders.
+- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
+ raise a ProgrammingError now.
-- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
- start byte and the continuation byte(s) are now considered invalid, instead
- of the number of bytes specified by the start byte.
- E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
- replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
- ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
- Previous versions returned a single u'\ufffd'.
+- Issue #10881: Fix test_site failures with OS X framework builds.
-- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
+- Issue #964437 Make IDLE help window non-modal.
+ Patch by Guilherme Polo and Roger Serwy.
-- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
- the interpreter with characters outside the Basic Multilingual Plane
- (higher than 0x10000).

+ module, like hashlib. (Patch by Roger Serwy)

- __hash__ in 3.x" warning. Also fix "XXX undetected error" that
- arises from the "Overriding __eq__ blocks inheritance ..." warning
- when turned into an exception: in this case the exception simply
- gets ignored.
+- Issue #13901: Prevent test_distutils failures on OS X with --enable-shared.
-- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'
- entries, consider the first one.
+- Issue #13676: Handle strings with embedded zeros correctly in sqlite3.
-- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
+- Issue #13506: Add '' to path for IDLE Shell when started and restarted with Restart Shell.
+ Original patches by Marco Scataglini and Roger Serwy.
-- In the unicode/str.format(), raise a ValueError when indexes to arguments are
- too large.
+- Issue #13806: The size check in audioop decompression functions was too
+ strict and could reject valid compressed data. Patch by Oleg Plakhotnyuk.
-- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
- and error handler, instead of writing to the C stderr file in utf-8
+- Issue #13885: CVE-2011-3389: the _ssl module would always disable the CBC
+ IV attack countermeasure.

-- Issue #1533: fix inconsistency in range function argument
- processing: any non-float non-integer argument is now converted to
- an integer (if possible) using its __int__ method. Previously, only
- small arguments were treated this way; larger arguments (those whose
- __int__ was outside the range of a C long) would produce a TypeError.
+- Issue #13589: Fix some serialization primitives in the aifc module.
+ Patch by Oleg Plakhotnyuk.
-- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize
- is passed to bytearray.
+- Issue #13803: Under Solaris, distutils doesn't include bitness
+ in the directory name.
-- Issue #8329: Don't return the same lists from select.select when no fds are
- changed.
+- Issue #13642: Unquote before b64encoding user:password during Basic
+ Authentication. Patch contributed by Joonas Kuorilehto and Michele Orrù.
-- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
+- Issue #13636: Weak ciphers are now disabled by default in the ssl module
+ (except when SSLv2 is explicitly asked for).
-- Issue #1583863: An unicode subclass can now override the __unicode__ method.
+- Issue #12798: Updated the mimetypes documentation.
-- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.

------
+- Issue #8035: urllib: Fix a bug where the client could remain stuck after a
+ redirection or an error.
-- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
- embedders of the interpreter to set sys.argv without also modifying
- sys.path. This helps fix `CVE-2008-5983
- <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
+- Issue #4625: If IDLE cannot write to its recent file or breakpoint

--------
+- tarfile.py: Correctly detect bzip2 compressed streams with blocksizes
+ other than 900k.

- the interpreter executable. This fixes a failure of test_httpservers
- on OS X.

+ This allows floats to round-trip without loss of precision.
-- Issue #7092: Fix the DeprecationWarnings emitted by the standard library
- when using the -3 flag. Patch by Florent Xicluna.
+- Issue #13439: Fix many errors in turtle docstrings.

+ raised when the wrapped raw file is non-blocking and the write would block.
+ Previous code assumed that the raw write() would raise BlockingIOError, but
+ RawIOBase.write() is defined to returned None when the call would block.
+ Patch by sbt.
-- Issue #5294: Fix the behavior of pdb's "continue" command when called
- in the top-level debugged frame.

+- 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 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.

- witnessed in test_httpservers.

- a non-infinite timeout. Also make that method friendlier with applications
- wanting to continue using the socket in clear-text mode, by disabling
- OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
+- Named tuples now work correctly with vars().
-- Issue #8484: Load all ciphers and digest algorithms when initializing
- the _ssl extension, such that verification of some SSL certificates
- doesn't fail because of an "unknown algorithm".
+- sys.setcheckinterval() now updates the current ticker count as well as
+ updating the check interval, so if the user decreases the check interval,
+ the ticker doesn't have to wind down to zero from the old starting point
+ before the new interval takes effect. And if the user increases the
+ interval, it makes sure the new limit takes effect right away rather have an
+ early task switch before recognizing the new interval.
-- Issue #4814: timeout parameter is now applied also for connections resulting
- from PORT/EPRT commands.
+- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
+ constructor has failed, e.g. because of an undeclared keyword argument. Patch
+ written by Oleg Oshmyan.
-- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response

-- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
