+What's New in Python 2.6.1
+==========================
+*Release date: 04-Dec-2008*
+Core and Builtins
+-----------------
+- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
+interpreter to abort ("Fatal Python error: Could not reset the stack!")
+instead of throwing a MemoryError.
+- Issue #4367: Python would segfault during compiling when the unicodedata
+module couldn't be imported and \N escapes were present.
+- Issue #4348: Some bytearray methods returned that didn't cause any change to
+the bytearray, returned the same bytearray instead of a copy.
+- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
+- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
+- Issue #4048: The parser module now correctly validates relative imports.
+- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
+exec statement.
+- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
+method does not return iterators for the 4th and 5th items.
+- Issue #4209: Enabling unicode_literals and the print_function in the same
+__future__ import didn't work.
+- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
+returned a path longer than MAX_PATH. (But It's doubtful this code path is
+really executed because I cannot move to such directory on win2k)
+- Issue #4069: When set.remove(element) is used with a set element, the element
+is temporarily replaced with an equivalent frozenset.  But the eventual
+KeyError would always report the empty frozenset([]) as the missing key. Now
+it correctly refers to the initial element.
+- Fixed C99 style comments in several files. Python is now C89 compatible
+again.
+Library
+-------
+- Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an
+exception.

+- Issue #4120: Exclude manifest from extension modules in VS2008.
+- Issue #4091: Install pythonxy.dll in system32 again.
+- Issue #4018: Disable "for me" installations on Vista.
+- Issue #3758: Add ``patchcheck`` build target to .PHONY.

+Py_UNICODE_ISSPACE macro in an extension module.
+Extension Modules
+-----------------
+- Issue #4365: Add crtassem.h constants to the msvcrt module.
+- Issue #4396: The parser module now correctly validates the with statement.

+was used with cProfile that returned an object that could not be converted
+into a float.
+- Issue #3950: Made turtle respect scale factors.
+- Issue #3547: Fixed ctypes structures bitfields of varying integer
+sizes.
+- Issue #3879: A regression in urllib.getproxies_enviroment was fixed.
+- Issue #3863: Disabled a unit test of fork being called from a thread
+when running on platforms known to exhibit OS bugs when attempting that.
+Build

+- Bug #3989: Package the 2to3 script (as 2to3.py) in the Windows
+installer.
+- Bug #3887: Package x64 version of CRT for AMD64 Windows binaries.
+What's New in Python 2.6 release candidate 2?
+=============================================
+*Release date: 17-Sep-2008*
+Core and Builtins
+-----------------
+Extension Modules
+-----------------
+- Security Issue #2: imageop did not validate arguments correctly and could
+segfault as a result.
+- Issue #3886: Possible integer overflows in the _hashopenssl module were
+closed.
+Tools/Demos
+-----------
+- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
+AttributeError instead of RuntimeError, depending in which C API call
+exactly the recursion limit is exceeded. Consequently, both exception types
+are caught and silenced.
+Build
+-----
+- Issue #3617: Include a licensing statement regarding the Microsoft
+C runtime in the Windows installer.
+What's New in Python 2.6 release candidate 1?
+=============================================
+*Release date: 12-Sep-2008*
+Core and Builtins
+-----------------
+- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
+- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
+PyString_FromFormat or PyErr_Format to display size_t values. The macro
+PY_FORMAT_SIZE_T is designed to select the correct format for the OS
+``printf`` function, whereas PyString_FromFormat has an independent
+implementation and uses "%zd" on all platforms for size_t values.
+This makes a difference on win64, where ``printf`` needs "%Id" to display
+64bit values.
+- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
+error.
+- Issue #3777: long() applied to a float object now always return a long
+object; previously an int would be returned for small values. the __long__
+method is allowed to return either an int or a long, but the behaviour of
+float objects should not change to respect backward compatibility.
+- Issue #3751: str.rpartition would perform a left-partition when called with
+a unicode argument.
+- Issue #3683: Fix compilation when --without-threads is given.
+- Issue #3668: Fix a memory leak with the "s*" argument parser in
+PyArg_ParseTuple and friends, which occurred when the argument for "s*"
+was correctly parsed but parsing of subsequent arguments failed.
+- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
+match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
+mechanism. In the process, fix a bug where isinstance() and issubclass(),
+when given a tuple of classes as second argument, were looking up
+__instancecheck__ / __subclasscheck__ on the tuple rather than on each
+type object.
+- Fix crashes on memory allocation failure found with failmalloc.
+- Fix memory leaks found with valgrind and update suppressions file.
+- Fix compiler warnings in opt mode which would lead to invalid memory reads.
+- Fix problem using wrong name in decimal module reported by pychecker.
+- Silenced another compiler warning about a used but not defined
+function 'stringlib_contains_obj'.
+- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
+``__delslice__``.
+- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
+library targets in the Makefile.
+- Issue #1204: The configure script now tests for additional libraries
+that may be required when linking against readline.  This fixes issues
+with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
+C-API
+-----
+- Aliased PyObject_Bytes to PyObject_Str.
+Library
+-------
+- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
+stack usage in the case of deeply nested objects.
+- Issue #3629: Fix sre "bytecode" validator for an end case.
+- Issue #3811: The Unicode database was updated to 5.1.
+- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
+silent misbehaviour when a single instance is nested in multiple
+with statements, or when the methods are invoked in the wrong order.
+- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
+- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
+return a list or None rather than a custom object.
+- Issue #1638033: Cookie.Morsel gained the httponly attribute.
+- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
+- Issue #3776: Deprecate the bsddb package for removal in 3.0.
+- Issue #3762: platform.architecture() fails if python is lanched via
+its symbolic link.
+- Issue #3772: Fixed regression problem in StreamHandler.emit().
+- Issue 600362: Relocated parse_qs() and parse_qsl(), from the cgi module
+to the urlparse one.  Added a PendingDeprecationWarning in the old
+module, it will be deprecated in the future.
+- Issue #2562: Fix distutils PKG-INFO writing logic to allow having
+non-ascii characters and Unicode in setup.py meta-data.
+- Issue #3726: Allow spaces in separators in logging configuration files.
+- Issue #3719: platform.architecture() fails if there are spaces in the
+path to the Python binary.
+- Issue 3602: Moved test.test_support.catch_warning() to
+warnings.catch_warnings() along with some API cleanup. Expanding the tests
+for catch_warnings() also led to an improvement in the raising of a
+DeprecationWarning related to warnings.warn_explicit().
+- The deprecation warnings for the old camelCase threading API were removed.
+- logging: fixed lack of use of encoding attribute specified on a stream.
+- Silenced a trivial compiler warning in the sqlite module.
+- Fixed two format strings in the _collections module.
+- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
+directory.
+- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
+non-integer floating point number.
+- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing
+SEM_VALUE_MAX.
+Extension Modules
+-----------------
+- Issue #2975: When compiling several extension modules with Visual Studio 2008
+from the same python interpreter, some environment variables would grow
+without limit.
+- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
+exploitation of poor argument checking.
+- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
+- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
+remaining ones have "pysqlite_" prefix.
+- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves
+concurrent access to the same SQLite database from multiple
+threads/processes.
+Tests
+-----
+- Issue #3781: Add test.test_support.check_warnings() as a convenience
+wrapper for warnings.catch_warnings() that makes it easier to check
+that expected warning messages are being reported.
+- Issue #3796: Some tests functions were not enabled in test_float.
+- Issue #3768: Move test_py3kwarn over to the new API for catch_warnings().
+Build
+-----
+- Issue #3833: Use a different upgrade code for Win64 installers.
+- Issue #2271: Set SecureCustomProperties so that installation will properly
+use the TARGETDIR even for unprivileged users.
+- Allow passing the MSI file name to merge.py.
+- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
+with GNU build target guidelines.
+What's New in Python 2.6 beta 3?
+================================
+*Release date: 20-Aug-2008*
+Core and Builtins
+-----------------
+- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
+Py_TPFLAGS_DEFAULT when not building the core.  This means 3rd party
+extensions do not automatically benefit from the class attribute
+cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
+to their tp_flags field if they care.  This is a backwards
+compatibility feature; in 3.0, all types will use the cache by
+default.
+- Keyword arguments can now follow starred arguments. (``f(a, *args,
+keyword=23)`` is now valid syntax.)
+- ctypes function pointers that are COM methods have a boolean True
+value again.
+- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
+by denying s# to parse objects that have a releasebuffer procedure,
+and introducing s*.
+- Issue #3537: Fix an assertion failure when an empty but presized dict
+object was stored in the freelist.
+- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
+ValueError consistently across platforms.
+- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
+(64bit Unix, for example), unichr() would truncate its argument and return
+u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
+- Apply security patches from Apple.
+- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
+PyErr_ExceptionMatches returns 0 when an exception occurs there.
+- Issue #1819: function calls with several named parameters are now on
+average 35% faster (as measured by pybench).
+- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
+the python debugger steps into a class statement: the free variables (local
+variables defined in an outer scope) would be deleted from the outer scope.
+- Issue #2620: Overflow checking when allocating or reallocating memory
+was not always being done properly in some python types and extension
+modules.  PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
+all been updated to perform better checks and places in the code that
+would previously leak memory on the error path when such an allocation
+failed have been fixed.
+Library
+-------
+- Issue #3612: Added some missing basic types in ctypes.wintypes.
+- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
+symtable.Symbol have been deprecated for removal in 3.0 and the next release.
+- Issue #2234: distutils failed for some versions of the cygwin compiler. The
+version reported by these tools does not necessarily follow the python
+version numbering scheme, so the module is less strict when parsing it.
+- Issue #2235: Added Py3k warnings for types which will become unhashable
+under the stricter __hash__ inheritance rules in 3.0. Several types
+which did not meet the rules for hash invariants and were already
+unhashable in 3.0 have now been explicitly flagged as unhashable in
+2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
+xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
+- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
+imported into the module but exposed as part of the module's API.
+- Remove an unneeded import of abc.ABCMeta from 'inspect'.
+- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
+- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
+- Issue #3575: Incremental decoder's decode function now takes bytearray
+by using 's*' instead of 't#'.
+- Issue #2222: Fixed reference leak when occured os.rename()
+fails unicode conversion on 2nd parameter. (windows only)
+- Issue 2464. urllib2 now supports a malformation in the URL received
+in a redirect.
+- Silence the DeprecationWarning raised when importing mimetools in
+BaseHTTPServer, cgi (and rfc822), httplib.
+- Issue #2776: fixed small issue when handling an URL with double slash
+after a 302 response in the case of not going through a proxy.
+- Issue #2676: in the email package, content-type parsing was hanging on
+pathological input because of quadratic or exponential behaviour of a
+regular expression.
+- Issue #3476: binary buffered reading through the new "io" library is now
+thread-safe.
+- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
+since mimetools itself is deprecated. Because modules are cached, all
+subsequent imports of rfc822 will not raise a visible DeprecationWarning.
+- Issue #3134: shutil referenced undefined WindowsError symbol.
+- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
+menu entries were not deleted.
+- Copied the implementation of reduce() to _functools.reduce() to have a
+version that did not raise a DeprecationWarning under -3.
+- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
+a MemoryError rather than silently stop the iteration.
+- Issue #3487: sre "bytecode" validator.  Passing invalid "re-bytecode"
+to _sre.compile() will now be rejected.  This should not affect anybody
+since the re.compile() function never generates invalid re-bytecode.
+- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
+upon first access it can be automatically initialized from the csv file if
+it wasn't initialized during instantiation.
+- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
+the reload() built-in has been removed.
+- Changed code in the following modules/packages to remove warnings raised
+while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
+ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
+filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
+pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
+subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
+threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
+- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
+raised an AttributeError.
+- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
+asking for a specific length. This problem only affected files opened
+using the new "io" module, not the built-in open() function.
+- Issue #3449: Update decimal module to use most recent specification
+(v. 1.68) and tests (v. 2.58) from IBM.
+- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
+- Issue 1592:  Improve error reporting when operations are attempted
+on a closed shelf.
+- Deprecate the "ast" parser function aliases.
+- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
+- Issue #3303: Fix a crash in locale.strcoll() when calling it with
+invalid arguments.
+- Issue #3302: Fix several crashes when calling locale's gettext functions
+with None arguments.
+- Issue #3389: Allow resolving dotted names for handlers in logging
+configuration files.
+- Deprecate the sunaudio module for removal in Python 3.0.
+- Issue #3394: zipfile.writestr sets external attributes when passed a
+file name rather than a ZipInfo instance, so files are extracted with
+mode 0600 rather than 000 under Unix.
+- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
+argument in python 2.5, this broke code that subclassed Popen to include its
+own poll method.  Fixed my moving _deadstate to an _internal_poll method.
+Build
+-----
+- Generate the PatternGrammar pickle during "make install".
+Documentation
+-------------
+- Issue #2235: the C API function PyObject_HashNotImplemented and its
+interaction with the tp_hash slot (added in 2.6b2) are now documented
+- Issue #643841: The language reference now provides more detailed
+coverage of the lookup process for special methods. The disclaimers
+regarding lack of coverage of new-style classes have also been
+removed, since the coverage is now fairly reasonable.
+What's New in Python 2.6 beta 2?
+================================
+*Release date: 17-Jul-2008*
+Core and Builtins
+-----------------
+- Issue #3156: Fix inconsistent behavior of the bytearray type: all
+its methods now allow for items objects that can be converted to
+an integer using operator.index().
+- Issue #3360: Fix incorrect parsing of '020000000000.0', which
+produced a ValueError instead of giving the correct float.
+- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
+for str.format().  This adds the prefix 0b, 0o, or 0x, respectively.
+- Issue #3008: the float type has a new instance method 'float.hex'
+and a new class method 'float.fromhex' to convert floating-point
+numbers to and from hexadecimal strings, respectively.
+- Issue #2235: __hash__ is once again inherited by default. To allow
+collections.Hashable to remain meaningful in the presence of the
+default hash implementation (object.__hash__), it is now possible
+to explicit block inheritance of hash by setting __hash__=None at
+the Python level, or tp_hash=PyObject_HashNotImplemented at the C
+level.
+- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
+the parent module cannot be found while performing an absolute import.
+This means that an incorrectly defined __package__ attribute will
+now only prevent relative imports in that module rather than causing
+all imports from that module to fail.
+- Issue #2517: Allow unicode messages in Exceptions again by correctly
+bypassing the instance dictionary when looking up __unicode__ on
+new-style classes.
+- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
+set to a custom object whose write() method happens to install
+another file in sys.stdout.
+- Issue #3088: Corrected a race condition in classes derived from
+threading.local: the first member set by a thread could be saved in
+another thread's dictionary.
+- Issue #3004: Minor change to slice.indices(): the start and stop
+arguments are now treated identically, making the behaviour easier
+to describe and understand.  For example, slice(None, -10,
+1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
+slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
+10, -1).
+- Issue #3219: Calling a function with repeated keyword arguments,
+f(a=2, a=23), would not cause a syntax error.  This was a regression
+from 2.4 caused by the switch to the new compiler.
+- Issue #2862: Make int and float freelist management consistent with
+other freelists.  Changes their CompactFreeList apis into
+ClearFreeList apis and calls them via gc.collect().
+Library
+-------
+- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
+api functions without holding the GIL, which could lead to a fatal
+error when they failed.
+- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
+- Issue #3395: fix reference in test_multiprocessing to old debugInfo method
+- Issue #3312: Fix two crashes in sqlite3.
+- Issue #1608818: Fix misbehavior in os.listdir() if readdir() fails.
+- Issue #3125: Remove copy_reg in multiprocessing and replace it with
+ForkingPickler.register() to resolve conflict with ctypes.
+- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
+- Issue #3313: Fixed a crash when a failed dlopen() call does not set
+a valid dlerror() message.
+- Issue #3258: Fixed a crash when a ctypes POINTER type to an
+incomplete structure was created.
+- Issue #3339: dummy_thread.acquire() should not return None.
+- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
+- Issue #3301: Bisect module behaved badly when lo was negative.
+- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
+both unnecessary (HTTP allows text content to be sent in several forms) and
+wrong because the actual transmitted size could differ from the
+content-length.  The problem had been corrected in the 2.4 branch, but never
+merged into trunk.
+- Issue #2663: add filtering capability to shutil.copytree().
+- Issue #1622: Correct interpretation of various ZIP header fields.
+- Issue #1526: Allow more than 64k files to be added to Zip64 file.
+- Issue #1746: Correct handling of zipfile archive comments (previously
+archives with comments over 4k were flagged as invalid). Allow writing
+Zip files with archives by setting the 'comment' attribute of a ZipFile.
+- Issue #449227: The rlcompleter module now adds "(" to callable objects
+when completed.
+- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
+handling is now the same as that of other special attributes like __name__).
+- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
+removal in Python 3.0 in favor of urllib2.urlopen().
+- Issue #2113: Fix error in subprocess.Popen if the select system call is
+interrupted by a signal.
+- Issue #3309: Fix bz2.BZFile iterator to release its internal lock
+properly when raising an exception due to the bz2file being closed.
+Prevents a deadlock.
+- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
+redundant ":443" port number designation when the connection is using the
+default https port (443).
+- Issue #874900: after an os.fork() call the threading module state is cleaned
+up in the child process to prevent deadlock and report proper thread counts
+if the new process uses the threading module.
+Tests
+-----
+- test.test_support.catch_warning now keeps track of all warnings it sees
+and is now better documented. Explicit unit tests for this context manager
+have been added to test_warnings.
+Build
+-----
+- Issue #3215: Build sqlite3 as sqlite3.dll, not sqlite3.pyd.
+Documentation
+-------------
+- Document that robotparser has been renamed to urllib.robotparser in
+Python 3.0.
+- Document that urlparse has been renamed to urllib.parse in Python 3.0.
+- Document that urllib2 is split across multiple modules and renamed in
+Python 3.0.
+- Document that urllib is split across multiple modules and renamed in
+Python 3.0.
+What's New in Python 2.6 beta 1?
+================================
+*Release date: 18-June-2008*
+Core and Builtins
+-----------------
+- Issue #3211: warnings.warn_explicit() did not guard against its 'registry'
+argument being anything other than a dict or None. Also fixed a bug in error
+handling when 'message' and 'category' were both set to None, triggering a
+bus error.
+- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
+holds the last (strong) reference to its referent.
+- Add future_builtins.ascii().
+- Several set methods now accept multiple arguments:  update(), union(),
+intersection(), intersection_update(), difference(), and difference_update().
+- Issue #2898: Added sys.getsizeof() to retrieve size of objects in bytes.
+- New environment variable PYTHONIOENCODING.
+- Patch #2488: Add sys.maxsize.
+- Issue #2353: file.xreadlines() now emits a Py3k warning.
+- Issue #2863: generators now have a ``gen.__name__`` attribute that
+equals ``gen.gi_code.co_name``, like ``func.__name___`` that equals
+``func.func_code.co_name``.  The repr() of a generator now also
+contains this name.
+- Issue #2831: enumerate() now has a ``start`` argument.
+- Issue #2801: fix bug in the float.is_integer method where a
+ValueError was sometimes incorrectly raised.

+attribute.
+- Issue #2196: hasattr() now lets exceptions which do not inherit
+Exception (KeyboardInterrupt, and SystemExit) propagate instead of
+ignoring them.
+- Added checks for integer overflows, contributed by Google. Some are
+only available if asserts are left in the code, in cases where they
+can't be triggered from Python code.

+What's New in Python 2.6 alpha 3?
+=================================
+*Release date: 08-May-2008*
+Core and builtins
+-----------------
+- Issue #2719: backported the ``next()`` builtin from Python 3.
+- Issue #2681: The octal literal ``0o8`` was incorrecly acctepted. Now
+it properly raises a SyntaxError.
+- Issue #2617: Reserved -J and -X arguments for Jython, IronPython and
+other implementations of Python.
+- Implemented PEP 370: Per user site-packages directory.
+Extension Modules
+-----------------
+- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
+two handlers that derive the same default base class.
+- Added kill, terminate and send_signal(sig) to subprocess.Popen.
+- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
+the cmath module.
+- Four new methods were added to the math and cmath modules: acosh,
+asinh, atanh and log1p.
+- zlib.decompressobj().flush(value) no longer crashes the interpreter
+when passed a value less than or equal to zero.
+- Issue #1631171: Re-implement the 'warnings' module in C (the
+original Python code has been kept as backup). This will allow for
+using the 'warning's machinery in such places as the parser where
+use of pure Python code is not possible.  Both the ``showarning()``
+and ``formatwarning()`` gain an optional 'line' argument which is
+not called by default for backwards-compatibility reasons. Setting
+``warnings.showwarning()`` to an implementation that lacks support
+for the ``line`` argument will raise a DeprecationWarning.
+Library
+-------
+- The audiodev module has been deprecated for removal in Python 3.0.
+- Issue #2750: Add the 'json' package. Based on simplejson 1.9 and
+contributed by Bob Ippolito.
+- Issue #1734346: Support Unicode file names for zipfiles.
+- Issue #2581: distutils: Vista UAC/elevation support for
+bdist_wininst.
+- Issue #2635: Fix bug in 'fix_sentence_endings' textwrap.fill option,
+where an extra space was added after a word containing (but not
+ending in) '.', '!' or '?'.
+- Add from_buffer() and from_buffer_copy() class methods to ctypes
+data types.
+- Issue #2682: ctypes callback functions no longer contain a cyclic
+reference to themselves.
+- The getpass module has been improved on Unix.  It now uses /dev/tty
+by default and uses stderr instead of stdout.  A GetPassWarning is
+issued when input echo cannot be controlled.
+- Issue #2014: Allow XML-RPC datetime objects to have dates before
+1900-01-01.
+- Issue #2439: Added new function pkgutil.get_data(), which is a
+convenience wrapper for the PEP 302 get_data() API.
+- Issue #2616: The ctypes.pointer() and ctypes.POINTER() functions are
+now implemented in C for better performance.
+- Issue #2408: The ``_types`` module, which was used as in
+implementation detail of the public ``types`` module, has been
+removed and replaced by pure python code.
+- Issue #2513: distutils on Windows is now capable of cross-compiling
+extension modules between 32 and 64 bit platforms.  See the distutls
+build documentation for more information.
+- Issue #815646: Individual file objects may now be used from multiple
+threads at once without fear of crashing the Python interpreter.  If
+file.close() is called while an object is in use by another thread
+an IOError exception will be raised and the file will not be closed.
+- The bundled libffi copy is now in sync with the recently released
+libffi3.0.5 version, apart from some small changes to
+Modules/_ctypes/libffi/configure.ac.
+- Issue #2385: distutils.core.run_script() makes __file__ available,
+so the controlled environment will more closely mirror the typical
+script environment.  This supports setup.py scripts that refer to
+data files.
+Tests
+-----
+- Issue #2550: The approach used by client/server code for obtaining
+ports to listen on in network-oriented tests has been refined in an
+effort to facilitate running multiple instances of the entire
+regression test suite in parallel without issue.
+test_support.bind_port() has been fixed such that it will always
+return a unique port -- which wasn't always the case with the
+previous implementation, especially if socket options had been set
+that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT).  The
+new implementation of bind_port() will actually raise an exception
+if it is passed an AF_INET/SOCK_STREAM socket with either the
+SO_REUSEADDR or SO_REUSEPORT socket option set.  Furthermore, if
+available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
+the socket it's been passed.  This currently only applies to
+Windows.  This option prevents any other sockets from binding to the
+host/port we've bound to, thus removing the possibility of the
+'non-deterministic' behaviour, as Microsoft puts it, that occurs
+when a second SOCK_STREAM socket binds and accepts to a host/port
+that's already been bound by another socket.  The optional preferred
+port parameter to bind_port() has been removed.  Under no
+circumstances should tests be hard coding ports!
+test_support.find_unused_port() has also been introduced, which will
+pass a temporary socket object to bind_port() in order to obtain an
+unused port.  The temporary socket object is then closed and
+deleted, and the port is returned.  This method should only be used
+for obtaining an unused port in order to pass to an external program
+(i.e. the -accept [port] argument to openssl's s_server mode) or as
+a parameter to a server-oriented class that doesn't give you direct
+access to the underlying socket used.
+Finally, test_support.HOST has been introduced, which should be used
+for the host argument of any relevant socket calls (i.e. bind and
+connect).
+The following tests were updated to following the new conventions:
+test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
+test_poplib, test_ftplib, test_telnetlib, test_socketserver,
+test_asynchat and test_socket_ssl.
+It is now possible for multiple instances of the regression test
+suite to run in parallel without issue.
+Build
+-----
+- Issue #1496032: On alpha, use -mieee when gcc is the compiler.
+- Issue #2544: On HP-UX systems, use 'gcc -shared' for linking when
+gcc is used as compiler.
+- Issue #2573: On MacOS X it is now possible to install the framework
+with a different name using --with-framework-name=NAME.
+C API
+-----
+- Added implementation of copysign, acosh, asinh, atanh and log1p to
+the new files Include/pymath.h and Python/pymath.h for platforms
+which provide the functions through their libm. The files also
+contains several helpers and constants for math.
+- Added a new convenience macro, PyErr_WarnPy3k, for issuing Py3k warnings.
+What's New in Python 2.6 alpha 2?

+- Issue #2355: add Py3k warning for buffer().
+- Issue #1477: With narrow Unicode builds, the unicode escape sequence
+\Uxxxxxxxx did not accept values outside the Basic Multilingual
+Plane.  This affected raw unicode literals and the
+'raw-unicode-escape' codec.  Now UTF-16 surrogates are generated in
+this case, like normal unicode literals and the 'unicode-escape'
+codec.
+- Issue #2348: add Py3k warning for file.softspace.
+- Issue #2346/#2347: add Py3k warnings for __methods__ and
+__members__.

+- Issue #2321: use pymalloc for unicode object string data to reduce
+memory usage in some circumstances.
+- PEP 3127: octal literals now start with "0o". Old-style octal
+literals are still valid. There are binary literals with a prefix of
+"0b".  This also affects int(x, 0).
+- Issue #2359: Adding deprecation warnings for array.{read,write}.
+- Issue #1779871: GNU gcc can now build Python on OS X because the
+flags -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd are no
+longer passed.
+- Add a warning when asserting a non-empty tuple which is always true.
+- Issue #2179: speed up with statement execution by storing the exit
+method on the stack instead of in a temporary variable (patch by
+Jeffrey Yaskin)
+- Issue #2238: Some syntax errors in *args and **kwargs expressions
+could give bogus error messages.
+- Issue #2143: Fix embedded readline() hang on SSL socket EOF.

+- Issue #2248: return the result of the QUIT command. from
+SMTP.quit().
+- Backport of Python 3.0's io module.
+- Issue #2482: Make sure that the coefficient of a Decimal is always
+stored as a str instance, not as a unicode instance.  This ensures
+that str(Decimal) is always an instance of str.
+- Issue #2478: fix failure of decimal.Decimal(0).sqrt()
+- Issue #2432: give DictReader the dialect and line_num attributes
+advertised in the docs.
+- Issue #2460: Make Ellipsis object copyable.
+- Issue #1681432: Add triangular distribution to the random module
+- Issue #2136: urllib2's auth handler now allows single-quoted realms
+in the WWW-Authenticate header.

+installation which do not have the win32all package installed.
+- Added support to platform.uname() to also report the machine and
+processor information on Windows XP and later. As a result,
+platform.machine() and platform.processor() will report this
+information as well.
+- The library implementing the 2to3 conversion, lib2to3, was added to
+the standard distribution.
+- Issue #1747858: Fix chown to work with large uid's and gid's on
+64-bit platforms.
+- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
+values on 32-bit vs. 64-bit python interpreters.  Both were correct,
+but they now both return a signed integer object for consistency.
+- Issue #1158: add %f format (fractions of a second represented as
+microseconds) to datetime objects.  Understood by both strptime and
+strftime.
+- Issue #705836: struct.pack(">f", x) now raises OverflowError on all
+platforms when x is too large to fit into an IEEE 754 float;

+exception, otherwise it raises ValueError).
+- Issue #1193577: A .shutdown() method has been added to SocketServers
+which terminates the .serve_forever() loop.
+- Issue #2220: handle rlcompleter attribute match failure more
+gracefully.

+files are used.  On all linux systems the --with-system-ffi
+configure option defaults to "yes".
+- Issue #1577: shutil.move() now calls os.rename() if the destination
+is a directory instead of copying-then-remove-source.

+What's New in Python 2.6 alpha 1?
+=================================
+*Release date: 29-Feb-2008*
+Core and builtins
+-----------------
+- Issue #2051: pyc and pyo files are no longer created with permission
+644. The mode is now inherited from the py file.
+- Issue #2067: file.__exit__() now calls subclasses' close() method.
+- Patch #1759: Backport of PEP 3129 class decorators.
+- Issue #1881: An internal parser limit has been increased. Also see
+issue 215555 for a discussion.
+- Added the future_builtins module, which contains hex() and oct().
+These are the PEP 3127 version of these functions, designed to be
+compatible with the hex() and oct() builtins from Python 3.0.  They
+differ slightly in their output formats from the existing, unchanged
+Python 2.6 builtins.  The expected usage of the future_builtins
+module is:
+from future_builtins import hex, oct
+- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
+exponents for exponents with absolute value < 100.  Follows C99
+standard.  This is a change on Windows, which would use 3 digits.
+Also, added 'n' to the formats that PyOS_ascii_formatd understands,
+so that any alterations it does to the resulting string will be
+available in stringlib/formatter.h (for float.__format__).
+- Implemented PEP 3101, Advanced String Formatting.  This adds a new
+builtin format(); a format() method for str and unicode; a
+__format__() method to object, str, unicode, int, long, float, and
+datetime; the class string.Formatter; and the C API
+PyObject_Format().
+- Fixed several potential crashes, all caused by specially crafted
+__del__ methods exploiting objects in temporarily inconsistent
+state.
+- Issue #2115: Important speedup in setting __slot__ attributes.  Also
+prevent a possible crash: an Abstract Base Class would try to access
+a slot on a registered virtual subclass.
+- Fixed repr() and str() of complex numbers with infinity or nan as
+real or imaginary part.
+- Clear all free lists during a gc.collect() of the highest generation
+in order to allow pymalloc to free more arenas. Python may give back
+memory to the OS earlier.
+- Issue #2045: Fix an infinite recursion triggered when printing a
+subclass of collections.defaultdict, if its default_factory is set
+to a bound method.
+- Fixed a minor memory leak in dictobject.c. The content of the free
+list was not freed on interpreter shutdown.
+- Limit free list of method and builtin function objects to 256
+entries each.
+- Patch #1953: Added ``sys._compact_freelists()`` and the C API
+functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
+to compact the internal free lists of pre-allocted ints and floats.
+- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
+calls.  Python expected the return type int but the fork familie
+returns pi_t.
+- Issue #1678380: Fix a bug that identifies 0j and -0j when they
+appear in the same code unit.
+- Issue #2025: Add tuple.count() and tuple.index() methods to comply
+with the collections.Sequence API.
+- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
+linebreak detection
+- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
+the internal lookup cache for ref leak tests.
+- Patch #1473257: generator objects gain a gi_code attribute. This is
+the same object as the func_code attribute of the function that
+produced the generator.
+- Issue #1920: "while 0" statements were completely removed by the
+compiler, even in the presence of an "else" clause, which is
+supposed to be run when the condition is false. Now the compiler
+correctly emits bytecode for the "else" suite.
+- A few crashers fixed: weakref_in_del.py (issue #1377858);
+loosing_dict_ref.py (issue #1303614, test67.py);
+borrowed_ref_[34].py (not in tracker).
+- Issue #1069410: The "can't load dll" message box on Windows is
+suppressed while an extension is loaded by calling SetErrorMode in
+dynload_win.c. The error is still reported properly.
+- Issue #1915: Python compiles with --enable-unicode=no again. However
+several extension methods and modules do not work without unicode
+support.
+- Issue #1882: when compiling code from a string, encoding cookies in the
+second line of code were not always recognized correctly.
+- Issue #1679: "0x" was taken as a valid integer literal.
+- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
+added.
+- sys.float_info / PyFloat_GetInfo: The floating point information
+object was converted from a dict to a specialized structseq object.
+- Patch #1816: Added sys.flags structseq. It exposes the status of
+most command line arguments and PYTHON* environment variables.
+- Objects/structseq.c: Implemented new structseq representation. The
+patch makes structseqs (e.g. the return value of os.stat) more
+readable.
+- Patch #1700288: added a type attribute cache that caches method
+accesses, resulting in speedups in heavily object-oriented code.
+- Bug #1776: __import__() no longer accepts filenames on any platform.
+The first parameter to __import__() must be a valid module name.
+- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
+- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
+envvar and sys.dont_write_bytecode attribute. All these can be set
+to forbid Python to attempt to write compiled bytecode files.
+- Improve some exception messages when Windows fails to load an
+extension module. Now we get for example '%1 is not a valid Win32
+application' instead of 'error code 193'.
+- Bug #1481296: Fixed long(float('nan')) != 0L.
+- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
+y) functions.
+- Issue #1635: Platform independent creation and representation of NaN
+and INF. float("nan"), float("inf") and float("-inf") now work on
+every platform with IEEE 754 semantics.
+- Compiler now generates simpler and faster code for dictionary
+literals.  The oparg for BUILD_MAP now indicates an estimated
+dictionary size.  There is a new opcode, STORE_MAP, for adding
+entries to the dictionary.
+- Issue #1638: %zd configure test fails on Linux.
+- Issue #1620: New property decorator syntax was modifying the
+decorator in place instead of creating a new decorator object.
+- Issue #1538: Avoid copying string in split/rsplit if the split char
+is not found.
+- Issue #1553: An erroneous __length_hint__ can make list() raise a
+SystemError.
+- PEP 366: Allow explicit relative imports when executing modules
+inside packages with the -m switch via a new module level
+__package__ attribute.
+- Issue #1402: Fix a crash on exit, when another thread is still
+running, and if the deallocation of its frames somehow calls the
+PyGILState_Ensure() / PyGILState_Release() functions.
+- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
+- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
+attribute of an empty cell object.
+- Issue #1460: The utf-7 incremental decoder did not accept truncated
+input.  It now correctly saves its state between chunks of data.
+- Patch #1739468: Directories and zipfiles containing a __main__.py
+file can now be directly executed by passing their name to the
+interpreter. The directory/zipfile is automatically inserted as the
+first entry in sys.path.
+- Issue #1265: Fix a problem with sys.settrace, if the tracing
+function uses a generator expression when at the same time the
+executed code is closing a paused generator.
+- sets and frozensets now have an isdisjoint() method.
+- optimize the performance of builtin.sum().
+- Fix warnings found by the new version of the Coverity checker.
+- The enumerate() builtin function is no longer bounded to sequences
+smaller than LONG_MAX.  Formerly, it raised an OverflowError.  Now,
+automatically shifts from ints to longs.
+- Issue #1686386: Tuple's tp_repr did not take into account the
+possibility of having a self-referential tuple, which is possible
+from C code.  Nor did object's tp_str consider that a type's tp_str
+could do something that could lead to an inifinite recursion.
+Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
+issues.
+- Issue #1164: It was possible to trigger deadlock when using the
+'print' statement to write to a file since the GIL was not released
+as needed.  Now PyObject_Print() does the right thing along with
+various tp_print implementations of the built-in types and those in
+the collections module.
+- Issue #1147: Exceptions were directly allowing string exceptions in
+their throw() method even though string exceptions no longer
+allowed.
+- Issue #1096: Prevent a segfault from getting the repr of a very
+deeply nested list by using the recursion counter.
+- Issue #1202533: Fix infinite recursion calls triggered by calls to
+PyObject_Call() never calling back out to Python code to trigger
+recursion depth updates/checks.  Required the creation of a static
+RuntimeError instance in case normalizing an exception put the
+recursion check value past its limit.  Fixes crashers
+infinite_rec_(1|2|4|5).py.
+- Patch #1031213: Decode source line in SyntaxErrors back to its
+original source encoding.
+- Patch #1673759: add a missing overflow check when formatting floats
+with %G.
+- Prevent expandtabs() on string and unicode objects from causing a
+segfault when a large width is passed on 32-bit platforms.
+- Issue #1733488: Fix compilation of bufferobject.c on AIX.
+- Issue #1722485: remove docstrings again when running with -OO.
+- Add new attribute names for function objects.  All the func_* become
+__*__ attributes.  (Some already existed, e.g., __doc__ and
+__name__.)
+- Add -3 option to the interpreter to warn about features that are
+deprecated and will be changed/removed in Python 3.0.
+- Patch #1686487: you can now pass any mapping after '**' in function
+calls.
+- except clauses may now be spelled either "except E, target:" or
+"except E as target:". This is to provide forwards compatibility
+with Python 3.0.
+- Deprecate BaseException.message as per PEP 352.
+- Issue #1303614: don't expose object's __dict__ when the dict is
+inherited from a builtin base.
+- When __slots__ are set to a unicode string, make it work the same as
+setting a plain string, ie don't expand to single letter identifiers.
+- Request #1191699:  Slices can now be pickled.
+- Request #1193128:  str.translate() now allows a None argument for
+translations that only remove characters without re-mapping the
+remaining characters.
+- Patch #1682205: a TypeError while unpacking an iterable is no longer
+masked by a generic one with the message "unpack non-sequence".
+- Remove unused file Python/fmod.c.
+- Bug #1683368: The object.__init__() and object.__new__() methods are
+now stricter in rejecting excess arguments.  The only time when
+either allows excess arguments is when it is not overridden and the
+other one is.  For backwards compatibility, when both are
+overridden, it is a deprecation warning (for now; maybe a Py3k
+warning later).  Also, type.__init__() insists on the same signature
+as supported by type.__new__().
+- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
+object to complex using its __complex__() method before falling back
+to the __float__() method. Therefore, the functions in the cmath
+module now can operate on objects that define a __complex__()
+method.
+- Patch #1623563: allow __class__ assignment for classes with
+__slots__.  The old and the new class are still required to have the
+same slot names.
+- Patch #1642547: Fix an error/crash when encountering syntax errors
+in complex if statements.
+- Patch #1462488: Python no longer segfaults when
+``object.__reduce_ex__()`` is called with an object that is faking
+its type.
+- Patch #1680015: Don't modify __slots__ tuple if it contains an
+unicode name.
+- Patch #1444529: the builtin compile() now accepts keyword arguments.
+- Bug #1678647: write a newline after printing an exception in any
+case, even when converting the value to a string failed.
+- The dir() function has been extended to call the __dir__() method on
+its argument, if it exists. If not, it will work like before. This
+allows customizing the output of dir() in the presence of a
+__getattr__().
+- Patch #922167: Python no longer segfaults when faced with infinitely
+self-recursive reload() calls (as reported by bug #742342).
+- Patch #1675981: remove unreachable code from ``type.__new__()``
+method.
+- Patch #1491866: change the complex() constructor to allow
+parthensized forms. This means complex(repr(x)) now works instead of
+raising a ValueError.
+- Patch #703779: unset __file__ in __main__ after running a file. This
+makes the filenames the warning module prints much more sensible
+when a PYTHONSTARTUP file is used.
+- Variant of patch #697613: don't exit the interpreter on a SystemExit
+exception if the -i command line option or PYTHONINSPECT environment
+variable is given, but break into the interactive interpreter just
+like on other exceptions or normal program exit.
+- Patch #1638879: don't accept strings with embedded NUL bytes in
+long().
+- Bug #1674503: close the file opened by execfile() in an error
+condition.
+- Patch #1674228: when assigning a slice (old-style), check for the
+sq_ass_slice instead of the sq_slice slot.
+- When printing an unraisable error, don't print exceptions. before
+the name.  This duplicates the behavior whening normally printing
+exceptions.
+- Bug #1653736: Properly discard third argument to
+slot_nb_inplace_power.
+- PEP 352: Raising a string exception now triggers a TypeError.
+Attempting to catch a string exception raises DeprecationWarning.
+- Bug #1377858: Fix the segfaulting of the interpreter when an object
+created a weakref on itself during a __del__ call for new-style
+classes (classic classes still have the bug).
+- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
+frame's thread state.
+- patch #1630975: Fix crash when replacing sys.stdout in
+sitecustomize.py.
+- Prevent seg fault on shutdown which could occur if an object raised
+a warning.
+- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, to
+avoid relying on atexit.
+- Bug #1590891: random.randrange don't return correct value for big
+number.
+- Patch #1586791: Better exception messages for some operations on
+strings, tuples and lists.
+- Bug #1067760: Deprecate passing floats to file.seek.
+- Bug #1591996: Correctly forward exception in instance_contains().
+- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
+- Bug #1576657: when setting a KeyError for a tuple key, make sure
+that the tuple isn't used as the "exception arguments tuple".
+- Bug #1565514: SystemError not raised on too many nested blocks.
+- Bug #1576174: WindowsError now displays the windows error code
+again, no longer the posix error code.
+- Patch #1549049: Support long values in structmember, issue warnings
+if the assigned value for structmember fields gets truncated.
+- Update the peephole optimizer to remove more dead code (jumps after
+returns) and inline unconditional jumps to returns.
+- Bug #1545497: when given an explicit base, int() did ignore NULs
+embedded in the string to convert.
+- Bug #1569998: break inside a try statement (outside a loop) is now
+recognized and rejected.
+- list.pop(x) accepts any object x following the __index__ protocol.
+- A number of places, including integer negation and absolute value,
+were fixed to not rely on undefined behaviour of the C compiler
+anymore.
+- Bug #1566800: make sure that EnvironmentError can be called with any
+number of arguments, as was the case in Python 2.4.
+- Patch #1567691: super() and new.instancemethod() now don't accept
+keyword arguments any more (previously they accepted them, but
+didn't use them).
+- Fix a bug in the parser's future statement handling that led to
+"with" not being recognized as a keyword after, e.g., this
+statement: from __future__ import division, with_statement
+- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).
+- Fix %zd string formatting on Mac OS X so it prints negative numbers.
+- Allow exception instances to be directly sliced again.
+- Bug #1551432: Exceptions do not define an explicit __unicode__
+method.  This allows calling unicode() on exceptions classes
+directly to succeed.
+- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
+Also make sure that every exception class has __module__ set to
+'exceptions'.
+- Bug #1550983: emit better error messages for erroneous relative
+imports (if not in package and if beyond toplevel package).
+- Overflow checking code in integer division ran afoul of new gcc
+optimizations.  Changed to be more standard-conforming.
+- Patch #1542451: disallow continue anywhere under a finally.
+- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
+- The return tuple from str.rpartition(sep) is (tail, sep, head) where
+head is the original string if sep was not found.
+- Bug #1520864: unpacking singleton tuples in list comprehensions and
+generator expressions (x for x, in ... ) works again.  Fixing this
+problem required changing the .pyc magic number.  This means that
+.pyc files generated before 2.5c2 will be regenerated.
+- ``with`` and ``as`` are now keywords.
+- Bug #1664966: Fix crash in exec if Unicode filename can't be
+decoded.
+- Issue #1537: Changed GeneratorExit's base class from Exception to
+BaseException.
+- Issue #1703448: A joined thread could show up in the
+threading.enumerate() list after the join() for a brief period until
+it actually exited.

+When too many positional arguments are passed, also a TypeError is
+raised instead of a ValueError.
+- Convert the internal ctypes array type cache to a WeakValueDict so
+that array types do not live longer than needed.
+- Issue #1786: pdb should use its own stdin/stdout around an exec call

+cannot be loaded in Python 2.5.
+- Issue #1455: The distutils package now supports VS 2005 and VS 2008
+for both the msvccompiler and cygwincompiler.
+- Issue #1531: tarfile.py: Read fileobj from the current offset, do
+not seek to the start.
+- Issue #1534: Added a dictionary sys.float_info with information
+about the internal floating point type to the sys module.
+- Issue #1429818: patch for trace and doctest modules so they play
+nicely together.
+- doctest made a bad assumption that a package's __loader__.get_data()
+method used universal newlines.
+- Issue #1705170: contextlib.contextmanager was still swallowing
+StopIteration in some cases. This should no longer happen.
+- Issue #1292: On alpha, arm, ppc, and s390 linux systems the

+- unittest now verifies more of its assumptions. In particular,
+TestCase and TestSuite subclasses (not instances) are no longer
+accepted in TestSuite.addTest(). This should cause no
+incompatibility since it never made sense with ordinary subclasses
+-- the failure just occurred later, with a more cumbersome
+exception.

+Allows the demo2 function to be executed on its own instead of only
+when the module is run as a script.

+- pybsddb.sf.net Bug #477182: Load the database flags at database open
+time so that opening a database previously created with the DB_DUP
+or DB_DUPSORT flag set will keep the proper behavior on subsequent
+opens.  Specifically: dictionary assignment to a DB object will
+replace all values for a given key when the database allows

+Tests
+-----
+- Refactor test_logging to use unittest.
+- Refactor test_profile and test_cprofile to use the same code to
+profile.
+- Make test_runpy reentrant by fixing _check_module to clear out any
+module being tested.  Was causing an error by __import__ doing a
+reload on the second run and thus suppressing bytecode recreation.
+- Capture socket connection resets and timeouts in test_socket_ssl and
+test_urllib2net and raise test.test_support.ResourceDenied.
+- Patch #1559413: Fix test_cmd_line if sys.executable contains a
+space.
+- Added test.test_support.TransientResource which is a context manager
+to surround calls to resources that are not guaranteed to work even
+if test.test_support.requires says that the resource should exist.
+- Added a test for slicing of an exception.
+- Added test.test_support.EnvironmentVarGuard.  It's a class that
+provides a context manager so that one can temporarily set or unset
+environment variables.
+- Added some tests for modulefinder.
+- Converted test_imp to use unittest.
+- Fix bsddb test_basics.test06_Transactions to check the version
+number properly.
+- test.test_support.catch_warning is a new context manager that can be
+used to catch the warnings issued by the warning framework.
+Tools
+-----
+- Tools/scripts/reindent.py now creates the backup file using
+shutil.copy to preserve user/group and permissions. Added also a
+--nobackup option to not create the backup if the user is concerned
+regarding this.  Check issue 1050828 for more details.
+- Tools/scripts/win_add2path.py was added. The simple script modifes
+the PATH environment var of the HKCU tree and adds the python bin
+and script directory.
+- Tools/18n/pygettext.py was added to the list of scripts installed by
+Tools/scripts/setup.py (tracker item 642309).

+patch #1563844).
+- Made some minor changes to pybench output to allow the user to see
+which Python version is running pybench.

+PCbuild/vs8to9.py was added to sync changes from PCbuild to
+PC/VS8.0.
+- Moved PCbuild/ directory for VS 2003 to PC/VS7.1 and renamed
+PCBuild9/ directory to PCBuild/.
+- Bug #1699: Define _BSD_SOURCE only on OpenBSD.
+- Bug #1608: use -fwrapv when GCC supports it.  This is important,
+newer GCC versions may optimize away overflow buffer overflow checks
+without this option!
+- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
+- Add a FAST_LOOPS build option that speeds-up looping by trading away
+periodic threadstate and signal checking in tight loops.  By

+4.1+.
+- Stop supporting AtheOS and cause a build error in configure for the
+platform.
+- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
+returned by python-config if Python was built with --enable-shared
+because that prevented the shared library from being used.
+- Patch #1569798: fix a bug in distutils when building Python from a
+directory within sys.exec_prefix.
+- Bug #1675511: Use -Kpic instead of -xcode=pic32 on Solaris/x86.

+- Patch #1576954: Update VC6 build directory; remove redundant files
+in VC7.
+- Bug #1568842: Fix test for uintptr_t.
+- Patch #1540470: for OpenBSD 4.0.
+- Fix build failure on kfreebsd and on the hurd.
+- Fix the build of the library reference in info format.
+- Allow Emacs 22 for building the documentation in info format.
+- Makefile.pre.in(buildbottest): Run an optional script
+pybuildbot.identify to include some information about the build
+environment.
+C API
+-----
+- Unified naming convention for free lists and their limits. All free
+lists in Object/ are named ``free_list``, the counter ``numfree``
+and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
+#ifndef block.
+- ``PySet_Add()`` can now modify a newly created frozenset.  Similarly
+to ``PyTuple_SetItem``, it can be used to populate a brand new
+frozenset; but it does not steal a reference to the added item.
+- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
+- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
+and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
+PyLong_FromSsize_t public functions.
+- Patch #1720595: add T_BOOL to the range of structmember types.
+- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
+``PyFloat_GetInfo()`` to the float API.
+- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
+of w# format code incorrectly truncated the length to an int, even
+when PY_SSIZE_T_CLEAN is set.  The str.decode method used to return
+incorrect results with huge strings.
+- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
+Py_TYPE and Py_REFCNT.
+- PEP 3123: Provide forward compatibility with Python 3.0, while
+keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
+and PyVarObject_HEAD_INIT.
+- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
+defined.
+- Patch #1733960: Allow T_LONGLONG to accept ints.
+- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
+- Added a new API function ``PyImport_ImportModuleNoBlock``.
+- Bug #1637022: Prefix AST symbols with _Py_.
+- Fix some leftovers from the conversion from int to Py_ssize_t
+(relevant to strings and sequences of more than 2**31 items).
+- Make _PyGILState_NoteThreadState() static, it was not used anywhere
+outside of pystate.c and should not be necessary.
+- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
+absolute imports. In earlier versions they might have used relative
+imports under some conditions.
+- Added case insensitive comparison methods ``PyOS_stricmp(char*,
+char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
+- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
+macro so it can be used as an expression.
+Windows
+-------
+- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
+requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
+macros are set to Win2k for x86/32bit builds and WinXP for AMD64
+builds.
+- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
+_CRT_NONSTDC_NO_DEPRECATE.
+- Bug #1216: Restore support for Visual Studio 2002.
+Mac
+---
+- cfmfile now raises a DeprecationWarning.
+- buildtools now raises a DeprecationWarning.
+- Removed the macfs module.  It had been deprecated since Python 2.5.
+This lead to the deprecation of macostools.touched() as it relied
+solely on macfs and was a no-op under OS X.
