+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

+
+- Issue #4091: Install pythonxy.dll in system32 again.
+
+- Issue #4018: Disable "for me" installations on Vista.
+
+- Issue #3758: Add ``patchcheck`` build target to .PHONY.
+
+- Issue #4204: Fixed module build errors on FreeBSD 4.
+
+C-API

+- Bug #3951: Py_USING_MEMORY_DEBUGGER should not be enabled by default.
+
+Library
+-------
+
+- Issue #3965: Allow repeated calls to turtle.Screen, by making it a
+ true singleton object.
+
+- Issue #3895: It was possible to crash the interpreter when an external timer

+
+
+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.

+What's New in Python 2.6 beta 1?
+================================
+
+*Release date: 18-June-2008*

+
+- 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().
+

+
+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.

+- Issue #2359: Adding deprecation warnings for array.{read,write}.
+
+- Issue #1779871: GNU gcc can now build Python on OS X because the

+ SMTP.quit().
+
+- Backport of Python 3.0's io module.
+
+- Issue #2482: Make sure that the coefficient of a Decimal is always

+ 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;
+ previously it only raised OverflowError on non IEEE 754 platforms.
+
+- Issues #2166, #1741 and #1531505: now distutils deals with HOME
+ correctly under win32
+
+- Patch #1858: distutils: added multiple server support in .pypirc
+
+- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
+ optional: it defaults to the traceback of the exception that is
+ currently being handled (is mandatory to be in the middle of an
+ 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.
+
+- Issue #2225: py_compile, when executed as a script, now returns a
+ non- zero status code if not all files could be compiled
+ successfully.
+
+- Bug #1725737: In distutils' sdist, exclude RCS, CVS etc. also in the
+ root directory, and also exclude .hg, .git, .bzr, and _darcs.
+
+- Issue #1872: The struct module typecode for _Bool has been changed
+ from 't' to '?'.
+
+- The bundled libffi copy is now in sync with the recently released
+ libffi3.0.4 version, apart from some small changes to
+ Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
+ 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.
+

+
+- test_nis no longer fails when test.test_support.verbose is true and
+ NIS is not set up on the testing machine.

+
+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.
+
+

+- Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', '').
+
+- 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.
+
+- Patch #787789: allow to pass custom TestRunner instances to
+ unittest's main() function.
+
+- Patches #1550273, #1550272: fix a few bugs in unittest and add a

+
+- Bug #494589: make ntpath.expandvars behave according to its
+ docstring.
+
+- Changed platform module API python_version_tuple() to actually
+ return a tuple (it used to return a list).
+
+- Added new platform module APIs python_branch(), python_revision(),
+ python_implementation() and linux_distribution().
+
+- Added support for IronPython and Jython to the platform module.
+
+- The sets module has been deprecated. Use the built-in set/frozenset
+ types instead.

+- Patch #1560695: Add .note.GNU-stack to ctypes' sysv.S so that ctypes

+ the first chunk fed to the decoder started with a BOM, but was
+ longer than 3 bytes.
+
+- The implementation of UnicodeError objects has been simplified
+ (start and end attributes are now stored directly as Py_ssize_t
+ members).
+
+- Issue #829951: In the smtplib module, SMTP.starttls() now complies
+ with RFC 3207 and forgets any knowledge obtained from the server not
+ obtained from the TLS negotiation itself. Patch contributed by Bill
+ Fenner.
+
+- Issue #1339: The smtplib.SMTP class has been refactored a bit such
+ that the SMTP.starttls() caller no longer needs to call ehlo()
+ beforehand. SMTP.starttls() now raises an exception of the server
+ does not claim to support starttls. Adds the
+ SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
+ Fenner.
+
+- Patch #1089358: Add signal.siginterrupt, a wrapper around
+ siginterrupt(3).

+- 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
+ duplicate values. DB users should use DB.put(k, v) when they want
+ to store duplicates; not DB[k] = v.
+
+- Add the bsddb.db.DBEnv.lock_id_free method.
+
+- Bug #1686475: Support stat'ing open files on Windows again.
+
+- Patch #1185447: binascii.b2a_qp() now correctly quotes binary

+ fails.
+
+- Speed up function calls into the math module.
+
+- Bug #1588217: don't parse "= " as a soft line break in binascii's

+ codepoints now.
+
+- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
+ mode by only placing a timeout on the select() if an input hook has
+ been defined. This prevents an interactive Python from waking up 10
+ times per second. Patch by Richard Boulton.
+
+- fixed a bug with bsddb.DB.stat: the flags and txn keyword arguments
+ were transposed.
+
+- Added support for linking the bsddb module against BerkeleyDB 4.5.x,

+ 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

+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.
+

+- 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.
+
+----
