124 rejected; (2) parsing of strings representing infinities and nans
125 was locale aware; and (3) the interpretation of fromhex('-nan')
126 didn't match that of float('-nan').
127
Eric Smitha985a3a2009-05-05 18:26:08 +0000128- Issue #5920: For float.__format__, change the behavior with the
129 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
130 to be like 'g' but with at least one decimal point and with a
131 default precision of 12. Previously, the behavior the same but with
132 a default precision of 6. This more closely matches str(), and
133 reduces surprises when adding alignment flags to the empty
134 presentation type. This also affects the new complex.__format__ in
135 the same way.
136
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000137- Issue #5890: in subclasses of 'property' the __doc__ attribute was

Eric Smithaca19e62009-04-22 13:29:05 +0000164- Implement PEP 378, Format Specifier for Thousands Separator, for
165 floats, ints, and longs.
166
167- Issue #5515: 'n' formatting for ints, longs, and floats handles
168 leading zero formatting poorly.

Eric Smith9139cc62009-04-30 00:58:58 +0000180 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000181
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000182- Issue #5759: float() didn't call __float__ on str subclasses.

200 untrackable objects are not tracked by the garbage collector. This can
201 reduce the size of collections and therefore the garbage collection overhead
202 on long-running programs, depending on their particular use of datatypes.
203
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000204- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

209 2**15 for the internal representation of integers, for performance
210 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
211 --enable-big-digits option to configure, which overrides the
212 default. Add sys.long_info structseq to provide information about
213 the internal format.
214

224
Brett Cannon6c4cff02009-03-11 04:51:06 +0000225- Issue #3652: Make the 'line' argument for warnings.showwarning() a
226 requirement. Means the DeprecationWarning from Python 2.6 can go away.

236 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
237 on a 64-bit system.
238
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000239- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
240 rotating the object pointer by 4 bits to the right.

244
Benjamin Petersone18ef192009-01-20 14:21:16 +0000245- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
246
Georg Brandl29c6a282009-04-05 20:23:13 +0000247- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000248 were suppressing all exceptions. These include list(), filter(), map(),
249 zip(), and bytearray().
250

321
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000322- Issue #4445: Replace "sizeof(PyStringObject)" with
323 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
324 str instances. On a typical machine this saves 3 bytes of memory
325 (on average) per string allocation.
326
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000327- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

329 instead of throwing a MemoryError.
330
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000331- Issue #3689: The list reversed iterator now supports __length_hint__

Vinay Sajip213faca2008-12-03 23:22:58 +0000337- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000338 method on file objects with closefd=False. The file descriptor is still
339 kept open but the file object behaves like a closed file. The ``FileIO``
340 object also got a new readonly attribute ``closefd``.
341
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000342- Issue #4348: Some bytearray methods returned that didn't cause any change to

356
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000357- Issue #4209: Enabling unicode_literals and the print_function in the same
358 __future__ import didn't work.
359
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000360- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000361 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000363- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
364 returned a path longer than MAX_PATH. (But It's doubtful this code path is
365 really executed because I cannot move to such directory on win2k)
366
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000367- Issue #4069: When set.remove(element) is used with a set element, the element
368 is temporarily replaced with an equivalent frozenset. But the eventual
369 KeyError would always report the empty frozenset([]) as the missing key. Now
370 it correctly refers to the initial element.
371
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000372- Issue #4509: Various issues surrounding resize of bytearray objects to

388 returned them on 64bit platforms.
389
Walter Dörwalded960ac2009-05-03 22:36:33 +0000390- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
391 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
392 step. This avoids problems with counting UTF-8 bytes that ignores the effect
393 of using the replace error handler in PyUnicode_DecodeUTF8().
394
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000395- Issue #3739: The unicode-internal encoder now reports the number of characters

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001575- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1576
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001577- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1578 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1579 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1580 ``printf`` function, whereas PyString_FromFormat has an independent
1581 implementation and uses "%zd" on all platforms for size_t values.
1582 This makes a difference on win64, where ``printf`` needs "%Id" to display
1583 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001585- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1589 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001593- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001600 was correctly parsed but parsing of subsequent arguments failed.
1601
Vinay Sajip35e3b032008-09-01 14:33:59 +00001602- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001603 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1604 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1605 when given a tuple of classes as second argument, were looking up
1606 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1607 type object.
1608
Neal Norwitz18aa3882008-08-24 05:04:52 +00001609- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001746What's New in Python 2.6 beta 3?
1747================================
1748
Barry Warsaw07a4a382008-08-21 01:15:08 +00001749*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001750
1751Core and Builtins
1752-----------------
1753
Guido van Rossumf8402962008-08-20 15:01:50 +00001754- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1755 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1756 extensions do not automatically benefit from the class attribute
1757 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1758 to their tp_flags field if they care. This is a backwards
1759 compatibility feature; in 3.0, all types will use the cache by
1760 default.
1761
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001762- Keyword arguments can now follow starred arguments. (``f(a, *args,
1763 keyword=23)`` is now valid syntax.)
1764
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001765- ctypes function pointers that are COM methods have a boolean True
1766 value again.
1767
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001768- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1769 by denying s# to parse objects that have a releasebuffer procedure,
1770 and introducing s*.
1771
Georg Brandl1e13ea92008-08-11 09:07:59 +00001772- Issue #3537: Fix an assertion failure when an empty but presized dict
1773 object was stored in the freelist.
1774
Mark Dickinsonb6467572008-08-04 21:30:09 +00001775- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1776 ValueError consistently across platforms.
1777
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001778- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1779 (64bit Unix, for example), unichr() would truncate its argument and return
1780 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1781
Neal Norwitze7d8be82008-07-31 17:17:14 +00001782- Apply security patches from Apple.
1783
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001784- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1785 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1786
Antoine Pitrou92f82162008-07-25 22:22:08 +00001787- Issue #1819: function calls with several named parameters are now on
1788 average 35% faster (as measured by pybench).
1789
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001790- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1791 the python debugger steps into a class statement: the free variables (local
1792 variables defined in an outer scope) would be deleted from the outer scope.
1793
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001794- Issue #2620: Overflow checking when allocating or reallocating memory
1795 was not always being done properly in some python types and extension
1796 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1797 all been updated to perform better checks and places in the code that
1798 would previously leak memory on the error path when such an allocation
1799 failed have been fixed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001801Library
1802-------
1803
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001804- Issue #3612: Added some missing basic types in ctypes.wintypes.
1805
Benjamin Petersone977ad42008-08-20 01:42:01 +00001806- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1807 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1808
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001809- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1810 version reported by these tools does not necessarily follow the python
1811 version numbering scheme, so the module is less strict when parsing it.
1812
Nick Coghlanf70385a2008-08-18 12:42:46 +00001813- Issue #2235: Added Py3k warnings for types which will become unhashable
1814 under the stricter __hash__ inheritance rules in 3.0. Several types
1815 which did not meet the rules for hash invariants and were already
1816 unhashable in 3.0 have now been explicitly flagged as unhashable in
1817 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1818 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1819
Brett Cannon88f801d2008-08-18 00:46:22 +00001820- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1821 imported into the module but exposed as part of the module's API.
1822
Brett Cannon7b96f072008-08-18 00:41:11 +00001823- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1824
Brett Cannon46225e72008-08-18 00:36:52 +00001825- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1826
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001827- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1828
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001829- Issue #3575: Incremental decoder's decode function now takes bytearray
1830 by using 's*' instead of 't#'.
1831
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001832- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001833 fails unicode conversion on 2nd parameter. (windows only)
1834
Facundo Batista94f243a2008-08-17 03:38:39 +00001835- Issue 2464. urllib2 now supports a malformation in the URL received
1836 in a redirect.
1837
Brett Cannonabe423e2008-08-16 21:47:07 +00001838- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001839 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001840
Facundo Batistaeb90b782008-08-16 14:44:07 +00001841- Issue #2776: fixed small issue when handling an URL with double slash
1842 after a 302 response in the case of not going through a proxy.
1843
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001844- Issue #2676: in the email package, content-type parsing was hanging on
1845 pathological input because of quadratic or exponential behaviour of a
1846 regular expression.
1847
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001848- Issue #3476: binary buffered reading through the new "io" library is now
1849 thread-safe.
1850
Brett Cannonbf3157b2008-08-14 05:00:03 +00001851- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1852 since mimetools itself is deprecated. Because modules are cached, all
1853 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1854
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001855- Issue #3134: shutil referenced undefined WindowsError symbol.
1856
Robert Schuppenies14646332008-08-10 11:01:53 +00001857- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1858 menu entries were not deleted.
1859
Brett Cannon83e81842008-08-09 23:30:55 +00001860- Copied the implementation of reduce() to _functools.reduce() to have a
1861 version that did not raise a DeprecationWarning under -3.
1862
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001863- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1864 a MemoryError rather than silently stop the iteration.
1865
Guido van Rossum59ce9012008-08-09 14:55:34 +00001866- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1867 to _sre.compile() will now be rejected. This should not affect anybody
1868 since the re.compile() function never generates invalid re-bytecode.
1869
Skip Montanaroa032bf42008-08-08 22:52:51 +00001870- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1871 upon first access it can be automatically initialized from the csv file if
1872 it wasn't initialized during instantiation.
1873
Brett Cannon3aa2a492008-08-06 22:28:09 +00001874- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1875 the reload() built-in has been removed.
1876
Brett Cannon7e30b672008-08-04 21:52:25 +00001877- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001878 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1882 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1883 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001884
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001885- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1886 raised an AttributeError.
1887
Benjamin Peterson01a24322008-07-28 23:35:27 +00001888- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001889 asking for a specific length. This problem only affected files opened
1890 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001891
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001892- Issue #3449: Update decimal module to use most recent specification
1893 (v. 1.68) and tests (v. 2.58) from IBM.
1894
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001895- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1896

1903
1904- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1905 invalid arguments.
1906
1907- Issue #3302: Fix several crashes when calling locale's gettext functions
1908 with None arguments.
1909
1910- Issue #3389: Allow resolving dotted names for handlers in logging
1911 configuration files.
1912
1913- Deprecate the sunaudio module for removal in Python 3.0.
1914
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001915- Issue #3394: zipfile.writestr sets external attributes when passed a
1916 file name rather than a ZipInfo instance, so files are extracted with
1917 mode 0600 rather than 000 under Unix.
1918
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001919- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1920 argument in python 2.5, this broke code that subclassed Popen to include its
1921 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001931- Issue #2235: the C API function PyObject_HashNotImplemented and its
1932 interaction with the tp_hash slot (added in 2.6b2) are now documented
1933
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001934- Issue #643841: The language reference now provides more detailed
1935 coverage of the lookup process for special methods. The disclaimers
1936 regarding lack of coverage of new-style classes have also been
1937 removed, since the coverage is now fairly reasonable.

1942
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001943*Release date: 17-Jul-2008*

1946-----------------
1947
Georg Brandl3e483f62008-07-16 22:57:41 +00001948- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1949 its methods now allow for items objects that can be converted to
1950 an integer using operator.index().
1951
Mark Dickinson64b7e502008-07-16 09:40:03 +00001952- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1953 produced a ValueError instead of giving the correct float.
1954
Eric Smitha5fa5a22008-07-16 00:11:49 +00001955- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1956 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1957
Mark Dickinson7103aa42008-07-15 19:08:33 +00001958- Issue #3008: the float type has a new instance method 'float.hex'
1959 and a new class method 'float.fromhex' to convert floating-point
1960 numbers to and from hexadecimal strings, respectively.
1961
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001962- Issue #2235: __hash__ is once again inherited by default. To allow
1963 collections.Hashable to remain meaningful in the presence of the
1964 default hash implementation (object.__hash__), it is now possible
1965 to explicit block inheritance of hash by setting __hash__=None at
1966 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1967 level.
1968
Nick Coghlanb028f502008-07-13 14:52:36 +00001969- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1970 the parent module cannot be found while performing an absolute import.
1971 This means that an incorrectly defined __package__ attribute will
1972 now only prevent relative imports in that module rather than causing
1973 all imports from that module to fail.
1974
Nick Coghlan14ff9942008-07-08 14:21:42 +00001975- Issue #2517: Allow unicode messages in Exceptions again by correctly
1976 bypassing the instance dictionary when looking up __unicode__ on
1977 new-style classes.
1978
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001979- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1980 set to a custom object whose write() method happens to install
1981 another file in sys.stdout.

1985 another thread's dictionary.
1986
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001987- Issue #3004: Minor change to slice.indices(): the start and stop
1988 arguments are now treated identically, making the behaviour easier
1989 to describe and understand. For example, slice(None, -10,
1990 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1991 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1992 10, -1).
1993
Georg Brandl278fc502008-07-19 12:46:12 +00001994- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002446 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002447
2448 This is controlled by the configure argument ``--with-universal-archs``:
2449
2450 - ``--with-universal-archs=all``: install 4-way universal
2451
2452 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2453
2454 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2455
2456 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002508- Issue #1631171: Re-implement the 'warnings' module in C (the
2509 original Python code has been kept as backup). This will allow for
2510 using the 'warning's machinery in such places as the parser where
2511 use of pure Python code is not possible. Both the ``showarning()``
2512 and ``formatwarning()`` gain an optional 'line' argument which is
2513 not called by default for backwards-compatibility reasons. Setting
2514 ``warnings.showwarning()`` to an implementation that lacks support
2515 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- Issue #2385: distutils.core.run_script() makes __file__ available,
2571 so the controlled environment will more closely mirror the typical
2572 script environment. This supports setup.py scripts that refer to
2573 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002578- Issue #2550: The approach used by client/server code for obtaining
2579 ports to listen on in network-oriented tests has been refined in an
2580 effort to facilitate running multiple instances of the entire
2581 regression test suite in parallel without issue.
2582 test_support.bind_port() has been fixed such that it will always
2583 return a unique port -- which wasn't always the case with the
2584 previous implementation, especially if socket options had been set
2585 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2586 new implementation of bind_port() will actually raise an exception
2587 if it is passed an AF_INET/SOCK_STREAM socket with either the
2588 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2589 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2590 the socket it's been passed. This currently only applies to
2591 Windows. This option prevents any other sockets from binding to the
2592 host/port we've bound to, thus removing the possibility of the
2593 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2594 when a second SOCK_STREAM socket binds and accepts to a host/port
2595 that's already been bound by another socket. The optional preferred
2596 port parameter to bind_port() has been removed. Under no
2597 circumstances should tests be hard coding ports!
2598
2599 test_support.find_unused_port() has also been introduced, which will
2600 pass a temporary socket object to bind_port() in order to obtain an
2601 unused port. The temporary socket object is then closed and
2602 deleted, and the port is returned. This method should only be used
2603 for obtaining an unused port in order to pass to an external program
2604 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2605 a parameter to a server-oriented class that doesn't give you direct
2606 access to the underlying socket used.
2607
2608 Finally, test_support.HOST has been introduced, which should be used
2609 for the host argument of any relevant socket calls (i.e. bind and
2610 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002611
2612 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002613 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002614 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2615 test_asynchat and test_socket_ssl.
2616
Georg Brandl3ee81df2008-05-17 18:14:43 +00002617 It is now possible for multiple instances of the regression test
2618 suite to run in parallel without issue.

2885-----------------
2886
Fred Drakea8ee94b2008-03-01 02:45:07 +00002887- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002888 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002889
Georg Brandlad61bc82008-02-23 15:11:18 +00002890- Issue #2067: file.__exit__() now calls subclasses' close() method.
2891
2892- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002893
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002894- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002895 issue 215555 for a discussion.
2896
Eric Smitha73fbe72008-02-23 03:09:44 +00002897- Added the future_builtins module, which contains hex() and oct().
2898 These are the PEP 3127 version of these functions, designed to be
2899 compatible with the hex() and oct() builtins from Python 3.0. They
2900 differ slightly in their output formats from the existing, unchanged
2901 Python 2.6 builtins. The expected usage of the future_builtins
2902 module is:
2903 from future_builtins import hex, oct
2904
Eric Smith7ef40bf2008-02-20 23:34:22 +00002905- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2906 exponents for exponents with absolute value < 100. Follows C99
2907 standard. This is a change on Windows, which would use 3 digits.
2908 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2909 so that any alterations it does to the resulting string will be
2910 available in stringlib/formatter.h (for float.__format__).
2911
Eric Smith5a3c1352008-02-19 13:21:56 +00002912- Implemented PEP 3101, Advanced String Formatting. This adds a new
2913 builtin format(); a format() method for str and unicode; a
2914 __format__() method to object, str, unicode, int, long, float, and
2915 datetime; the class string.Formatter; and the C API
2916 PyObject_Format().
2917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Fixed several potential crashes, all caused by specially crafted
2919 __del__ methods exploiting objects in temporarily inconsistent
2920 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002921
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002922- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923 prevent a possible crash: an Abstract Base Class would try to access
2924 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002925
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926- Fixed repr() and str() of complex numbers with infinity or nan as
2927 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002928
Georg Brandl3ee81df2008-05-17 18:14:43 +00002929- Clear all free lists during a gc.collect() of the highest generation
2930 in order to allow pymalloc to free more arenas. Python may give back
2931 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Issue #2045: Fix an infinite recursion triggered when printing a
2934 subclass of collections.defaultdict, if its default_factory is set
2935 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002936
Christian Heimesf75dbef2008-02-08 00:11:31 +00002937- Fixed a minor memory leak in dictobject.c. The content of the free
2938 list was not freed on interpreter shutdown.
2939
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940- Limit free list of method and builtin function objects to 256
2941 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002942
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2944 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002945 to compact the internal free lists of pre-allocted ints and floats.
2946
Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2948 calls. Python expected the return type int but the fork familie
2949 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002950
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2952 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2955 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002960- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2961 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002962
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963- Patch #1473257: generator objects gain a gi_code attribute. This is
2964 the same object as the func_code attribute of the function that
2965 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002966
Georg Brandl3ee81df2008-05-17 18:14:43 +00002967- Issue #1920: "while 0" statements were completely removed by the
2968 compiler, even in the presence of an "else" clause, which is
2969 supposed to be run when the condition is false. Now the compiler
2970 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002971
Guido van Rossumeead05f2008-01-24 18:21:02 +00002972- A few crashers fixed: weakref_in_del.py (issue #1377858);
2973 loosing_dict_ref.py (issue #1303614, test67.py);
2974 borrowed_ref_[34].py (not in tracker).
2975
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002976- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002977 suppressed while an extension is loaded by calling SetErrorMode in
2978 dynload_win.c. The error is still reported properly.
2979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002981 several extension methods and modules do not work without unicode
2982 support.
2983
Georg Brandl26543b12008-01-21 18:36:51 +00002984- Issue #1882: when compiling code from a string, encoding cookies in the
2985 second line of code were not always recognized correctly.
2986
Georg Brandl14404b62008-01-19 19:27:05 +00002987- Issue #1679: "0x" was taken as a valid integer literal.
2988
Georg Brandl6caad7d2008-01-26 14:19:22 +00002989- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002990 added.
2991
Christian Heimesc94e2b52008-01-14 04:13:37 +00002992- sys.float_info / PyFloat_GetInfo: The floating point information
2993 object was converted from a dict to a specialized structseq object.
2994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Patch #1816: Added sys.flags structseq. It exposes the status of
2996 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Objects/structseq.c: Implemented new structseq representation. The

3000 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003001
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003024 and INF. float("nan"), float("inf") and float("-inf") now work on
3025 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003026
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Compiler now generates simpler and faster code for dictionary
3028 literals. The oparg for BUILD_MAP now indicates an estimated
3029 dictionary size. There is a new opcode, STORE_MAP, for adding
3030 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Issue #1265: Fix a problem with sys.settrace, if the tracing
3065 function uses a generator expression when at the same time the
3066 executed code is closing a paused generator.

3071
Neal Norwitz44f326e2007-10-05 05:29:17 +00003072- Fix warnings found by the new version of the Coverity checker.
3073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- The enumerate() builtin function is no longer bounded to sequences
3075 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3076 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Issue #1686386: Tuple's tp_repr did not take into account the
3079 possibility of having a self-referential tuple, which is possible
3080 from C code. Nor did object's tp_str consider that a type's tp_str
3081 could do something that could lead to an inifinite recursion.
3082 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3083 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003084
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Issue #1164: It was possible to trigger deadlock when using the
3086 'print' statement to write to a file since the GIL was not released
3087 as needed. Now PyObject_Print() does the right thing along with
3088 various tp_print implementations of the built-in types and those in
3089 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Issue #1147: Exceptions were directly allowing string exceptions in
3092 their throw() method even though string exceptions no longer
3093 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Issue #1096: Prevent a segfault from getting the repr of a very
3096 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003097
Brett Cannon1e534b52007-09-07 04:18:30 +00003098- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099 PyObject_Call() never calling back out to Python code to trigger
3100 recursion depth updates/checks. Required the creation of a static
3101 RuntimeError instance in case normalizing an exception put the
3102 recursion check value past its limit. Fixes crashers
3103 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003104

Neal Norwitz0ac60192007-05-27 04:08:54 +00003118- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119 __*__ attributes. (Some already existed, e.g., __doc__ and
3120 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003121
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003122- Add -3 option to the interpreter to warn about features that are
3123 deprecated and will be changed/removed in Python 3.0.
3124
Georg Brandl2134e752007-05-21 20:34:16 +00003125- Patch #1686487: you can now pass any mapping after '**' in function
3126 calls.
3127
Collin Winter62903052007-05-18 23:11:24 +00003128- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003129 "except E as target:". This is to provide forwards compatibility
3130 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003131
Brett Cannon229cee22007-05-05 01:34:02 +00003132- Deprecate BaseException.message as per PEP 352.
3133
Georg Brandl3ee81df2008-05-17 18:14:43 +00003134- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003135 inherited from a builtin base.
3136
Vinay Sajip8549ce32007-05-06 17:53:37 +00003137- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003138 setting a plain string, ie don't expand to single letter identifiers.
3139
Raymond Hettinger13936692007-04-11 18:40:58 +00003140- Request #1191699: Slices can now be pickled.
3141
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003142- Request #1193128: str.translate() now allows a None argument for
3143 translations that only remove characters without re-mapping the
3144 remaining characters.
3145
Georg Brandl5cb76c12007-03-21 09:00:39 +00003146- Patch #1682205: a TypeError while unpacking an iterable is no longer

3150
Guido van Rossum143b5642007-03-23 04:58:42 +00003151- Bug #1683368: The object.__init__() and object.__new__() methods are
3152 now stricter in rejecting excess arguments. The only time when
3153 either allows excess arguments is when it is not overridden and the
3154 other one is. For backwards compatibility, when both are
3155 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003156 warning later). Also, type.__init__() insists on the same signature
3157 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003158
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3160 object to complex using its __complex__() method before falling back
3161 to the __float__() method. Therefore, the functions in the cmath
3162 module now can operate on objects that define a __complex__()
3163 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003164
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Patch #1623563: allow __class__ assignment for classes with
3166 __slots__. The old and the new class are still required to have the
3167 same slot names.

3174 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003175
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176- Patch #1680015: Don't modify __slots__ tuple if it contains an

3180
Georg Brandl7b9c5552007-03-12 14:30:05 +00003181- Bug #1678647: write a newline after printing an exception in any
3182 case, even when converting the value to a string failed.
3183
Georg Brandl871f1bc2007-03-12 13:17:36 +00003184- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185 its argument, if it exists. If not, it will work like before. This
3186 allows customizing the output of dir() in the presence of a
3187 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003188
Collin Winter276887b2007-03-12 16:11:39 +00003189- Patch #922167: Python no longer segfaults when faced with infinitely
3190 self-recursive reload() calls (as reported by bug #742342).
3191

Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Patch #1491866: change the complex() constructor to allow
3196 parthensized forms. This means complex(repr(x)) now works instead of
3197 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003198
Georg Brandlaa2321b2007-03-07 00:40:28 +00003199- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003200 makes the filenames the warning module prints much more sensible
3201 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003202
Georg Brandl49aafc92007-03-07 00:34:46 +00003203- Variant of patch #697613: don't exit the interpreter on a SystemExit
3204 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205 variable is given, but break into the interactive interpreter just
3206 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003214- Patch #1674228: when assigning a slice (old-style), check for the
3215 sq_ass_slice instead of the sq_slice slot.
3216
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217- When printing an unraisable error, don't print exceptions. before
3218 the name. This duplicates the behavior whening normally printing
3219 exceptions.

3276
Armin Rigo7ccbca92006-10-04 12:17:45 +00003277- A number of places, including integer negation and absolute value,

3846 incompatibility since it never made sense with ordinary subclasses
3847 -- the failure just occurred later, with a more cumbersome
3848 exception.

4062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4130 with RFC 3207 and forgets any knowledge obtained from the server not
4131 obtained from the TLS negotiation itself. Patch contributed by Bill
4132 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004135 that the SMTP.starttls() caller no longer needs to call ehlo()
4136 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137 does not claim to support starttls. Adds the
4138 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4139 Fenner.

Georg Brandl56112892008-01-20 13:59:46 +00004176- Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``.
4177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00004182 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- itertools.chain() now has an alternate constructor,

4208 contents before adding elements from the iterable. This fix brings
4209 the behavior into line with that for list.__init__().

4219 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4220 silently miscode subclasses of those types. Now, it raises a
4221 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004222

Georg Brandl3ee81df2008-05-17 18:14:43 +00004237 time so that opening a database previously created with the DB_DUP
4238 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4239 opens. Specifically: dictionary assignment to a DB object will
4240 replace all values for a given key when the database allows
4241 duplicate values. DB users should use DB.put(k, v) when they want
4242 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004243

4249 characters with ASCII value less than 32. Also, it correctly quotes
4250 dots only if they occur on a single line, as opposed to the previous
4251 behavior of quoting dots if they are the second character of any
4252 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004253

4575-----
4576
Georg Brandl3ee81df2008-05-17 18:14:43 +00004577- Unified naming convention for free lists and their limits. All free
4578 lists in Object/ are named ``free_list``, the counter ``numfree``
4579 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4580 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004581
Georg Brandl3ee81df2008-05-17 18:14:43 +00004582- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4583 to ``PyTuple_SetItem``, it can be used to populate a brand new
4584 frozenset; but it does not steal a reference to the added item.

4589 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4590 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004591
4592- Patch #1720595: add T_BOOL to the range of structmember types.
4593
4594- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4595 ``PyFloat_GetInfo()`` to the float API.
4596
Georg Brandl3ee81df2008-05-17 18:14:43 +00004597- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4598 of w# format code incorrectly truncated the length to an int, even
4599 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4600 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004601
Georg Brandl3ee81df2008-05-17 18:14:43 +00004602- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4603 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004605- PEP 3123: Provide forward compatibility with Python 3.0, while
4606 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4607 and PyVarObject_HEAD_INIT.

4610 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004611
4612- Patch #1733960: Allow T_LONGLONG to accept ints.

4619
4620- Fix some leftovers from the conversion from int to Py_ssize_t
4621 (relevant to strings and sequences of more than 2**31 items).
4622
4623- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4624 outside of pystate.c and should not be necessary.
4625
Georg Brandl3ee81df2008-05-17 18:14:43 +00004626- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4627 absolute imports. In earlier versions they might have used relative
4628 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004629
Georg Brandl3ee81df2008-05-17 18:14:43 +00004630- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4631 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004632
Georg Brandl3ee81df2008-05-17 18:14:43 +00004633- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004640- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4641 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4642 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4643 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004644

Georg Brandl3ee81df2008-05-17 18:14:43 +00004658- Removed the macfs module. It had been deprecated since Python 2.5.
4659 This lead to the deprecation of macostools.touched() as it relied
4660 solely on macfs and was a no-op under OS X.
