16
Antoine Pitrou4595e512010-06-11 21:48:02 +000017- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
18 the interpreter with characters outside the Basic Multilingual Plane
19 (higher than 0x10000).
20
Mark Dickinson80068da2010-06-05 11:59:41 +000021- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsonb671c292010-06-05 12:15:35 +000022 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
23 arises from the "Overriding __eq__ blocks inheritance ..." warning
24 when turned into an exception: in this case the exception simply
25 gets ignored.

Mark Dickinsone02c9d22010-05-07 13:23:18 +000039- Issue #1533: fix inconsistency in range function argument
40 processing: any non-float non-integer argument is now converted to

69 embedders of the interpreter to set sys.argv without also modifying
70 sys.path. This helps fix `CVE-2008-5983
71 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

Barry Warsaw90971e02009-04-07 01:54:02 +00001290 for *nix machines for negative handles and large int handles. Without this

1330 do an explicit seek to the end of file (so that e.g. tell() returns the
1331 file size rather than 0). This is consistent with the behaviour of the
1332 traditional 2.x file object.

1365
1366- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1367 302 conformant loader) will now work correctly in most cases (they
1368 are still subject to the constraints that exist for all code running
1369 from inside a module loaded via a PEP 302 loader and attempting to

1528What's New in Python 2.6.1
1529==========================
1530
1531*Release date: 04-Dec-2008*
1532
1533Core and Builtins
1534-----------------
1535
1536- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1537 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1538 instead of throwing a MemoryError.
1539
1540- Issue #4367: Python would segfault during compiling when the unicodedata
1541 module couldn't be imported and \N escapes were present.
1542
1543- Issue #4348: Some bytearray methods returned that didn't cause any change to
1544 the bytearray, returned the same bytearray instead of a copy.
1545
1546- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1547
1548- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1549
1550- Issue #4048: The parser module now correctly validates relative imports.
1551
1552- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1553 exec statement.
1554
1555- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1556 method does not return iterators for the 4th and 5th items.
1557
1558- Issue #4209: Enabling unicode_literals and the print_function in the same
1559 __future__ import didn't work.
1560
1561- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1562 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1563 really executed because I cannot move to such directory on win2k)
1564
1565- Issue #4069: When set.remove(element) is used with a set element, the element
1566 is temporarily replaced with an equivalent frozenset. But the eventual
1567 KeyError would always report the empty frozenset([]) as the missing key. Now

1719
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001720- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1721 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1722 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1723 ``printf`` function, whereas PyString_FromFormat has an independent
1724 implementation and uses "%zd" on all platforms for size_t values.
1725 This makes a difference on win64, where ``printf`` needs "%Id" to display
1726 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001743 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001745- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001746 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1747 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1748 when given a tuple of classes as second argument, were looking up
1749 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1750 type object.

Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001877- Issue #2271: Set SecureCustomProperties so that installation will properly
1878 use the TARGETDIR even for unprivileged users.
1879
Martin v. Löwis67543a92008-09-08 12:02:45 +00001880- Allow passing the MSI file name to merge.py.
1881
Vinay Sajip844f7412008-09-09 13:42:08 +00001882- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001883 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001886What's New in Python 2.6 beta 3?
1887================================
1888
Barry Warsaw07a4a382008-08-21 01:15:08 +00001889*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001890
1891Core and Builtins
1892-----------------
1893
Guido van Rossumf8402962008-08-20 15:01:50 +00001894- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1895 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1896 extensions do not automatically benefit from the class attribute
1897 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1898 to their tp_flags field if they care. This is a backwards
1899 compatibility feature; in 3.0, all types will use the cache by
1900 default.
1901
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001902- Keyword arguments can now follow starred arguments. (``f(a, *args,
1903 keyword=23)`` is now valid syntax.)
1904
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001905- ctypes function pointers that are COM methods have a boolean True
1906 value again.
1907
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001908- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1909 by denying s# to parse objects that have a releasebuffer procedure,
1910 and introducing s*.
1911
Georg Brandl1e13ea92008-08-11 09:07:59 +00001912- Issue #3537: Fix an assertion failure when an empty but presized dict
1913 object was stored in the freelist.
1914
Mark Dickinsonb6467572008-08-04 21:30:09 +00001915- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1916 ValueError consistently across platforms.
1917
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001918- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1919 (64bit Unix, for example), unichr() would truncate its argument and return
1920 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1921
Neal Norwitze7d8be82008-07-31 17:17:14 +00001922- Apply security patches from Apple.
1923
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001924- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1925 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1926
Antoine Pitrou92f82162008-07-25 22:22:08 +00001927- Issue #1819: function calls with several named parameters are now on
1928 average 35% faster (as measured by pybench).
1929
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001930- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1931 the python debugger steps into a class statement: the free variables (local
1932 variables defined in an outer scope) would be deleted from the outer scope.
1933
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001934- Issue #2620: Overflow checking when allocating or reallocating memory
1935 was not always being done properly in some python types and extension
1936 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1937 all been updated to perform better checks and places in the code that
1938 would previously leak memory on the error path when such an allocation
1939 failed have been fixed.
1940
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001941Library
1942-------
1943
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001944- Issue #3612: Added some missing basic types in ctypes.wintypes.
1945
Benjamin Petersone977ad42008-08-20 01:42:01 +00001946- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1947 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1948
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001949- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1950 version reported by these tools does not necessarily follow the python
1951 version numbering scheme, so the module is less strict when parsing it.
1952
Nick Coghlanf70385a2008-08-18 12:42:46 +00001953- Issue #2235: Added Py3k warnings for types which will become unhashable
1954 under the stricter __hash__ inheritance rules in 3.0. Several types
1955 which did not meet the rules for hash invariants and were already
1956 unhashable in 3.0 have now been explicitly flagged as unhashable in
1957 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1958 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1959
Brett Cannon88f801d2008-08-18 00:46:22 +00001960- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1961 imported into the module but exposed as part of the module's API.
1962
Brett Cannon7b96f072008-08-18 00:41:11 +00001963- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1964
Brett Cannon46225e72008-08-18 00:36:52 +00001965- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1966
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001967- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1968
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001969- Issue #3575: Incremental decoder's decode function now takes bytearray
1970 by using 's*' instead of 't#'.
1971
Jesus Cea585ad8a2009-07-02 15:37:21 +00001972- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001973 fails unicode conversion on 2nd parameter. (windows only)
1974
Facundo Batista94f243a2008-08-17 03:38:39 +00001975- Issue 2464. urllib2 now supports a malformation in the URL received
1976 in a redirect.
1977
Brett Cannonabe423e2008-08-16 21:47:07 +00001978- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001979 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001980
Facundo Batistaeb90b782008-08-16 14:44:07 +00001981- Issue #2776: fixed small issue when handling an URL with double slash
1982 after a 302 response in the case of not going through a proxy.
1983
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001984- Issue #2676: in the email package, content-type parsing was hanging on
1985 pathological input because of quadratic or exponential behaviour of a
1986 regular expression.
1987
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001988- Issue #3476: binary buffered reading through the new "io" library is now
1989 thread-safe.
1990
Brett Cannonbf3157b2008-08-14 05:00:03 +00001991- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1992 since mimetools itself is deprecated. Because modules are cached, all
1993 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1994
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001995- Issue #3134: shutil referenced undefined WindowsError symbol.
1996
Robert Schuppenies14646332008-08-10 11:01:53 +00001997- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1998 menu entries were not deleted.
1999
Brett Cannon83e81842008-08-09 23:30:55 +00002000- Copied the implementation of reduce() to _functools.reduce() to have a
2001 version that did not raise a DeprecationWarning under -3.
2002
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002003- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2004 a MemoryError rather than silently stop the iteration.
2005
Guido van Rossum59ce9012008-08-09 14:55:34 +00002006- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2007 to _sre.compile() will now be rejected. This should not affect anybody
2008 since the re.compile() function never generates invalid re-bytecode.
2009
Skip Montanaroa032bf42008-08-08 22:52:51 +00002010- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2011 upon first access it can be automatically initialized from the csv file if
2012 it wasn't initialized during instantiation.
2013
Brett Cannon3aa2a492008-08-06 22:28:09 +00002014- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2015 the reload() built-in has been removed.
2016
Brett Cannon7e30b672008-08-04 21:52:25 +00002017- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002018 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2021 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2022 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2023 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002025- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2026 raised an AttributeError.
2027
Benjamin Peterson01a24322008-07-28 23:35:27 +00002028- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002029 asking for a specific length. This problem only affected files opened
2030 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002031
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002032- Issue #3449: Update decimal module to use most recent specification
2033 (v. 1.68) and tests (v. 2.58) from IBM.
2034
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002035- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2043
2044- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2045 invalid arguments.
2046
2047- Issue #3302: Fix several crashes when calling locale's gettext functions
2048 with None arguments.
2049
2050- Issue #3389: Allow resolving dotted names for handlers in logging
2051 configuration files.
2052

2054
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002055- Issue #3394: zipfile.writestr sets external attributes when passed a
2056 file name rather than a ZipInfo instance, so files are extracted with
2057 mode 0600 rather than 000 under Unix.
2058
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002059- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2060 argument in python 2.5, this broke code that subclassed Popen to include its
2061 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2069-------------
2070
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002071- Issue #2235: the C API function PyObject_HashNotImplemented and its
2072 interaction with the tp_hash slot (added in 2.6b2) are now documented
2073
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002074- Issue #643841: The language reference now provides more detailed
2075 coverage of the lookup process for special methods. The disclaimers
2076 regarding lack of coverage of new-style classes have also been
2077 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002080What's New in Python 2.6 beta 2?
2081================================
2082
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002083*Release date: 17-Jul-2008*
2084
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002085Core and Builtins
2086-----------------
2087
Georg Brandl3e483f62008-07-16 22:57:41 +00002088- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2089 its methods now allow for items objects that can be converted to
2090 an integer using operator.index().
2091
Mark Dickinson64b7e502008-07-16 09:40:03 +00002092- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2093 produced a ValueError instead of giving the correct float.
2094
Eric Smitha5fa5a22008-07-16 00:11:49 +00002095- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2096 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2097
Mark Dickinson7103aa42008-07-15 19:08:33 +00002098- Issue #3008: the float type has a new instance method 'float.hex'
2099 and a new class method 'float.fromhex' to convert floating-point
2100 numbers to and from hexadecimal strings, respectively.
2101
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002102- Issue #2235: __hash__ is once again inherited by default. To allow
2103 collections.Hashable to remain meaningful in the presence of the
2104 default hash implementation (object.__hash__), it is now possible
2105 to explicit block inheritance of hash by setting __hash__=None at
2106 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2107 level.
2108
Nick Coghlanb028f502008-07-13 14:52:36 +00002109- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2110 the parent module cannot be found while performing an absolute import.
2111 This means that an incorrectly defined __package__ attribute will
2112 now only prevent relative imports in that module rather than causing
2113 all imports from that module to fail.
2114
Nick Coghlan14ff9942008-07-08 14:21:42 +00002115- Issue #2517: Allow unicode messages in Exceptions again by correctly
2116 bypassing the instance dictionary when looking up __unicode__ on
2117 new-style classes.
2118
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002119- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2120 set to a custom object whose write() method happens to install
2121 another file in sys.stdout.
2122
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002123- Issue #3088: Corrected a race condition in classes derived from
2124 threading.local: the first member set by a thread could be saved in
2125 another thread's dictionary.
2126
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002127- Issue #3004: Minor change to slice.indices(): the start and stop
2128 arguments are now treated identically, making the behaviour easier
2129 to describe and understand. For example, slice(None, -10,
2130 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2131 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2132 10, -1).
2133
Georg Brandl278fc502008-07-19 12:46:12 +00002134- Issue #3219: Calling a function with repeated keyword arguments,
2135 f(a=2, a=23), would not cause a syntax error. This was a regression
2136 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002137
Georg Brandl278fc502008-07-19 12:46:12 +00002138- Issue #2862: Make int and float freelist management consistent with
2139 other freelists. Changes their CompactFreeList apis into
2140 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002145- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2146 api functions without holding the GIL, which could lead to a fatal
2147 error when they failed.
2148
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002149- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2158 ForkingPickler.register() to resolve conflict with ctypes.
2159
Vinay Sajip51e65192008-07-18 09:01:10 +00002160- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2585 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002586 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002587
2588 This is controlled by the configure argument ``--with-universal-archs``:
2589
2590 - ``--with-universal-archs=all``: install 4-way universal
2591
2592 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2593
2594 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2595
2596 This option should be used in combination with ``--enable-universalsdk=``.

2635 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002636
Christian Heimese74c8f22008-04-19 02:23:57 +00002637- Added kill, terminate and send_signal(sig) to subprocess.Popen.
2638

2640 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00002641

Georg Brandl3ee81df2008-05-17 18:14:43 +00002648- Issue #1631171: Re-implement the 'warnings' module in C (the
2649 original Python code has been kept as backup). This will allow for
2650 using the 'warning's machinery in such places as the parser where
2651 use of pure Python code is not possible. Both the ``showarning()``
2652 and ``formatwarning()`` gain an optional 'line' argument which is
2653 not called by default for backwards-compatibility reasons. Setting
2654 ``warnings.showwarning()`` to an implementation that lacks support
2655 for the ``line`` argument will raise a DeprecationWarning.

2679
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002680- The getpass module has been improved on Unix. It now uses /dev/tty
2681 by default and uses stderr instead of stdout. A GetPassWarning is
2682 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002683

Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002698 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002718- Issue #2550: The approach used by client/server code for obtaining
2719 ports to listen on in network-oriented tests has been refined in an
2720 effort to facilitate running multiple instances of the entire
2721 regression test suite in parallel without issue.
2722 test_support.bind_port() has been fixed such that it will always
2723 return a unique port -- which wasn't always the case with the
2724 previous implementation, especially if socket options had been set
2725 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2726 new implementation of bind_port() will actually raise an exception
2727 if it is passed an AF_INET/SOCK_STREAM socket with either the
2728 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2729 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2730 the socket it's been passed. This currently only applies to
2731 Windows. This option prevents any other sockets from binding to the
2732 host/port we've bound to, thus removing the possibility of the
2733 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2734 when a second SOCK_STREAM socket binds and accepts to a host/port
2735 that's already been bound by another socket. The optional preferred
2736 port parameter to bind_port() has been removed. Under no
2737 circumstances should tests be hard coding ports!
2738
2739 test_support.find_unused_port() has also been introduced, which will
2740 pass a temporary socket object to bind_port() in order to obtain an
2741 unused port. The temporary socket object is then closed and
2742 deleted, and the port is returned. This method should only be used
2743 for obtaining an unused port in order to pass to an external program
2744 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2745 a parameter to a server-oriented class that doesn't give you direct
2746 access to the underlying socket used.
2747
2748 Finally, test_support.HOST has been introduced, which should be used
2749 for the host argument of any relevant socket calls (i.e. bind and
2750 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002751
2752 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002754 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2755 test_asynchat and test_socket_ssl.
2756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757 It is now possible for multiple instances of the regression test
2758 suite to run in parallel without issue.

3024Core and builtins
3025-----------------
3026
Fred Drakea8ee94b2008-03-01 02:45:07 +00003027- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003028 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003029
Georg Brandlad61bc82008-02-23 15:11:18 +00003030- Issue #2067: file.__exit__() now calls subclasses' close() method.
3031
3032- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003033
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003034- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003035 issue 215555 for a discussion.
3036
Eric Smitha73fbe72008-02-23 03:09:44 +00003037- Added the future_builtins module, which contains hex() and oct().
3038 These are the PEP 3127 version of these functions, designed to be
3039 compatible with the hex() and oct() builtins from Python 3.0. They
3040 differ slightly in their output formats from the existing, unchanged
3041 Python 2.6 builtins. The expected usage of the future_builtins
3042 module is:
3043 from future_builtins import hex, oct
3044
Eric Smith7ef40bf2008-02-20 23:34:22 +00003045- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3046 exponents for exponents with absolute value < 100. Follows C99
3047 standard. This is a change on Windows, which would use 3 digits.
3048 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3049 so that any alterations it does to the resulting string will be
3050 available in stringlib/formatter.h (for float.__format__).
3051
Eric Smith5a3c1352008-02-19 13:21:56 +00003052- Implemented PEP 3101, Advanced String Formatting. This adds a new
3053 builtin format(); a format() method for str and unicode; a
3054 __format__() method to object, str, unicode, int, long, float, and
3055 datetime; the class string.Formatter; and the C API
3056 PyObject_Format().
3057
Georg Brandl3ee81df2008-05-17 18:14:43 +00003058- Fixed several potential crashes, all caused by specially crafted
3059 __del__ methods exploiting objects in temporarily inconsistent
3060 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003062- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063 prevent a possible crash: an Abstract Base Class would try to access
3064 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003065
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Fixed repr() and str() of complex numbers with infinity or nan as
3067 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003068
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069- Clear all free lists during a gc.collect() of the highest generation
3070 in order to allow pymalloc to free more arenas. Python may give back
3071 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003072
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073- Issue #2045: Fix an infinite recursion triggered when printing a
3074 subclass of collections.defaultdict, if its default_factory is set
3075 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003076
Christian Heimesf75dbef2008-02-08 00:11:31 +00003077- Fixed a minor memory leak in dictobject.c. The content of the free
3078 list was not freed on interpreter shutdown.
3079
Georg Brandl5a7eca12010-03-21 19:29:04 +00003080- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003082
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3084 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003085 to compact the internal free lists of pre-allocted ints and floats.
3086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3088 calls. Python expected the return type int but the fork familie
3089 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3092 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003093
Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3095 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003096
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3098 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003099
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3101 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Patch #1473257: generator objects gain a gi_code attribute. This is
3104 the same object as the func_code attribute of the function that
3105 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Issue #1920: "while 0" statements were completely removed by the
3108 compiler, even in the presence of an "else" clause, which is
3109 supposed to be run when the condition is false. Now the compiler
3110 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003111
Guido van Rossumeead05f2008-01-24 18:21:02 +00003112- A few crashers fixed: weakref_in_del.py (issue #1377858);
3113 loosing_dict_ref.py (issue #1303614, test67.py);
3114 borrowed_ref_[34].py (not in tracker).
3115
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003116- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003117 suppressed while an extension is loaded by calling SetErrorMode in
3118 dynload_win.c. The error is still reported properly.
3119
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003121 several extension methods and modules do not work without unicode
3122 support.
3123
Georg Brandl26543b12008-01-21 18:36:51 +00003124- Issue #1882: when compiling code from a string, encoding cookies in the
3125 second line of code were not always recognized correctly.
3126
Georg Brandl14404b62008-01-19 19:27:05 +00003127- Issue #1679: "0x" was taken as a valid integer literal.
3128
Georg Brandl6caad7d2008-01-26 14:19:22 +00003129- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003130 added.
3131
Christian Heimesc94e2b52008-01-14 04:13:37 +00003132- sys.float_info / PyFloat_GetInfo: The floating point information
3133 object was converted from a dict to a specialized structseq object.
3134
Georg Brandl3ee81df2008-05-17 18:14:43 +00003135- Patch #1816: Added sys.flags structseq. It exposes the status of
3136 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003137
Georg Brandl3ee81df2008-05-17 18:14:43 +00003138- Objects/structseq.c: Implemented new structseq representation. The
3139 patch makes structseqs (e.g. the return value of os.stat) more
3140 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003141
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142- Patch #1700288: added a type attribute cache that caches method
3143 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003144
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003145- Bug #1776: __import__() no longer accepts filenames on any platform.
3146 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003147

3149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3151 envvar and sys.dont_write_bytecode attribute. All these can be set
3152 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Improve some exception messages when Windows fails to load an
3155 extension module. Now we get for example '%1 is not a valid Win32
3156 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Bug #1481296: Fixed long(float('nan')) != 0L.

3161 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003162
Christian Heimes0a8143f2007-12-18 23:22:54 +00003163- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164 and INF. float("nan"), float("inf") and float("-inf") now work on
3165 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Compiler now generates simpler and faster code for dictionary
3168 literals. The oparg for BUILD_MAP now indicates an estimated
3169 dictionary size. There is a new opcode, STORE_MAP, for adding
3170 entries to the dictionary.

3200 file can now be directly executed by passing their name to the
3201 interpreter. The directory/zipfile is automatically inserted as the
3202 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003203
Georg Brandl3ee81df2008-05-17 18:14:43 +00003204- Issue #1265: Fix a problem with sys.settrace, if the tracing
3205 function uses a generator expression when at the same time the
3206 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003207
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003208- sets and frozensets now have an isdisjoint() method.
3209

3213
Georg Brandl5a7eca12010-03-21 19:29:04 +00003214- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003215 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3216 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003217
Georg Brandl3ee81df2008-05-17 18:14:43 +00003218- Issue #1686386: Tuple's tp_repr did not take into account the
3219 possibility of having a self-referential tuple, which is possible
3220 from C code. Nor did object's tp_str consider that a type's tp_str
3221 could do something that could lead to an inifinite recursion.
3222 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3223 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003225- Issue #1164: It was possible to trigger deadlock when using the
3226 'print' statement to write to a file since the GIL was not released
3227 as needed. Now PyObject_Print() does the right thing along with
3228 various tp_print implementations of the built-in types and those in
3229 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Issue #1147: Exceptions were directly allowing string exceptions in
3232 their throw() method even though string exceptions no longer
3233 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003234
Georg Brandl3ee81df2008-05-17 18:14:43 +00003235- Issue #1096: Prevent a segfault from getting the repr of a very
3236 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003237
Brett Cannon1e534b52007-09-07 04:18:30 +00003238- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239 PyObject_Call() never calling back out to Python code to trigger
3240 recursion depth updates/checks. Required the creation of a static
3241 RuntimeError instance in case normalizing an exception put the
3242 recursion check value past its limit. Fixes crashers
3243 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003258- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259 __*__ attributes. (Some already existed, e.g., __doc__ and
3260 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003261
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003262- Add -3 option to the interpreter to warn about features that are
3263 deprecated and will be changed/removed in Python 3.0.
3264
Georg Brandl2134e752007-05-21 20:34:16 +00003265- Patch #1686487: you can now pass any mapping after '**' in function
3266 calls.
3267
Collin Winter62903052007-05-18 23:11:24 +00003268- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269 "except E as target:". This is to provide forwards compatibility
3270 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003271
Brett Cannon229cee22007-05-05 01:34:02 +00003272- Deprecate BaseException.message as per PEP 352.
3273
Georg Brandl3ee81df2008-05-17 18:14:43 +00003274- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003275 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003277- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003278 setting a plain string, ie don't expand to single letter identifiers.
3279
Raymond Hettinger13936692007-04-11 18:40:58 +00003280- Request #1191699: Slices can now be pickled.
3281
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003282- Request #1193128: str.translate() now allows a None argument for
3283 translations that only remove characters without re-mapping the
3284 remaining characters.
3285
Georg Brandl5cb76c12007-03-21 09:00:39 +00003286- Patch #1682205: a TypeError while unpacking an iterable is no longer
3287 masked by a generic one with the message "unpack non-sequence".
3288
Neal Norwitzaa754b72007-03-21 06:39:48 +00003289- Remove unused file Python/fmod.c.
3290
Guido van Rossum143b5642007-03-23 04:58:42 +00003291- Bug #1683368: The object.__init__() and object.__new__() methods are
3292 now stricter in rejecting excess arguments. The only time when
3293 either allows excess arguments is when it is not overridden and the
3294 other one is. For backwards compatibility, when both are
3295 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003296 warning later). Also, type.__init__() insists on the same signature
3297 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3300 object to complex using its __complex__() method before falling back
3301 to the __float__() method. Therefore, the functions in the cmath
3302 module now can operate on objects that define a __complex__()
3303 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003304
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- Patch #1623563: allow __class__ assignment for classes with
3306 __slots__. The old and the new class are still required to have the
3307 same slot names.

3313 ``object.__reduce_ex__()`` is called with an object that is faking
3314 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Patch #1680015: Don't modify __slots__ tuple if it contains an

3320
Georg Brandl7b9c5552007-03-12 14:30:05 +00003321- Bug #1678647: write a newline after printing an exception in any
3322 case, even when converting the value to a string failed.
3323
Georg Brandl871f1bc2007-03-12 13:17:36 +00003324- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003325 its argument, if it exists. If not, it will work like before. This
3326 allows customizing the output of dir() in the presence of a
3327 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003328
Collin Winter276887b2007-03-12 16:11:39 +00003329- Patch #922167: Python no longer segfaults when faced with infinitely

3336 parthensized forms. This means complex(repr(x)) now works instead of
3337 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003338
Georg Brandlaa2321b2007-03-07 00:40:28 +00003339- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003340 makes the filenames the warning module prints much more sensible
3341 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003342
Georg Brandl49aafc92007-03-07 00:34:46 +00003343- Variant of patch #697613: don't exit the interpreter on a SystemExit
3344 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003345 variable is given, but break into the interactive interpreter just
3346 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003354- Patch #1674228: when assigning a slice (old-style), check for the
3355 sq_ass_slice instead of the sq_slice slot.
3356
Georg Brandl3ee81df2008-05-17 18:14:43 +00003357- When printing an unraisable error, don't print exceptions. before
3358 the name. This duplicates the behavior whening normally printing
3359 exceptions.

3368 created a weakref on itself during a __del__ call for new-style
3369 classes (classic classes still have the bug).

3968 Python would crash instead of raising an error.

3987 -- the failure just occurred later, with a more cumbersome
3988 exception.

4201 partial fix for Bug #1574584.
4202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004269- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4270 with RFC 3207 and forgets any knowledge obtained from the server not
4271 obtained from the TLS negotiation itself. Patch contributed by Bill
4272 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004273
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004275 that the SMTP.starttls() caller no longer needs to call ehlo()
4276 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004277 does not claim to support starttls. Adds the
4278 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4279 Fenner.

Georg Brandl56112892008-01-20 13:59:46 +00004316- Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``.
4317
Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00004321- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00004322 works as expected. ``mmap.find`` also takes an optional ``end``

4359 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4360 silently miscode subclasses of those types. Now, it raises a
4361 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004362

Georg Brandl3ee81df2008-05-17 18:14:43 +00004377 time so that opening a database previously created with the DB_DUP
4378 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4379 opens. Specifically: dictionary assignment to a DB object will
4380 replace all values for a given key when the database allows
4381 duplicate values. DB users should use DB.put(k, v) when they want
4382 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004383

4389 characters with ASCII value less than 32. Also, it correctly quotes
4390 dots only if they occur on a single line, as opposed to the previous
4391 behavior of quoting dots if they are the second character of any
4392 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004393

4715-----
4716
Georg Brandl3ee81df2008-05-17 18:14:43 +00004717- Unified naming convention for free lists and their limits. All free
4718 lists in Object/ are named ``free_list``, the counter ``numfree``
4719 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4720 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004721
Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4723 to ``PyTuple_SetItem``, it can be used to populate a brand new
4724 frozenset; but it does not steal a reference to the added item.

4733
4734- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4735 ``PyFloat_GetInfo()`` to the float API.
4736
Georg Brandl3ee81df2008-05-17 18:14:43 +00004737- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4738 of w# format code incorrectly truncated the length to an int, even
4739 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4740 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004741
Georg Brandl3ee81df2008-05-17 18:14:43 +00004742- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4760- Fix some leftovers from the conversion from int to Py_ssize_t
4761 (relevant to strings and sequences of more than 2**31 items).
4762
4763- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4764 outside of pystate.c and should not be necessary.
4765
Georg Brandl3ee81df2008-05-17 18:14:43 +00004766- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4767 absolute imports. In earlier versions they might have used relative
4768 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004769
Georg Brandl3ee81df2008-05-17 18:14:43 +00004770- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4771 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004772
Georg Brandl3ee81df2008-05-17 18:14:43 +00004773- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004780- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4781 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4782 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4783 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004784

Georg Brandl3ee81df2008-05-17 18:14:43 +00004798- Removed the macfs module. It had been deprecated since Python 2.5.
4799 This lead to the deprecation of macostools.touched() as it relied
