1026 do an explicit seek to the end of file (so that e.g. tell() returns the
1027 file size rather than 0). This is consistent with the behaviour of the

1063 302 conformant loader) will now work correctly in most cases (they

1224What's New in Python 2.6.1
1225==========================
1226
1227*Release date: 04-Dec-2008*
1228
1229Core and Builtins
1230-----------------
1231
1232- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1233 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1234 instead of throwing a MemoryError.
1235
1236- Issue #4367: Python would segfault during compiling when the unicodedata
1237 module couldn't be imported and \N escapes were present.
1238
1239- Issue #4348: Some bytearray methods returned that didn't cause any change to
1240 the bytearray, returned the same bytearray instead of a copy.
1241
1242- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1243
1244- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1245
1246- Issue #4048: The parser module now correctly validates relative imports.
1247
1248- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1249 exec statement.
1250
1251- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1252 method does not return iterators for the 4th and 5th items.
1253
1254- Issue #4209: Enabling unicode_literals and the print_function in the same
1255 __future__ import didn't work.
1256
1257- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1258 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1259 really executed because I cannot move to such directory on win2k)
1260
1261- Issue #4069: When set.remove(element) is used with a set element, the element
1262 is temporarily replaced with an equivalent frozenset. But the eventual
1263 KeyError would always report the empty frozenset([]) as the missing key. Now
1264 it correctly refers to the initial element.
1265
1266- Fixed C99 style comments in several files. Python is now C89 compatible
1267 again.
1268
1269Library

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001414- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1415
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001416- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1417 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1418 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1419 ``printf`` function, whereas PyString_FromFormat has an independent
1420 implementation and uses "%zd" on all platforms for size_t values.
1421 This makes a difference on win64, where ``printf`` needs "%Id" to display
1422 64bit values.

1428 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001439 was correctly parsed but parsing of subsequent arguments failed.
1440
Vinay Sajip35e3b032008-09-01 14:33:59 +00001441- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001442 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1443 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1444 when given a tuple of classes as second argument, were looking up
1445 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1446 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00001590- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1591 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1592 extensions do not automatically benefit from the class attribute
1593 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1594 to their tp_flags field if they care. This is a backwards
1595 compatibility feature; in 3.0, all types will use the cache by
1596 default.
1597
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001598- Keyword arguments can now follow starred arguments. (``f(a, *args,
1599 keyword=23)`` is now valid syntax.)
1600
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001601- ctypes function pointers that are COM methods have a boolean True
1602 value again.
1603
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001604- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1605 by denying s# to parse objects that have a releasebuffer procedure,
1606 and introducing s*.
1607
Georg Brandl1e13ea92008-08-11 09:07:59 +00001608- Issue #3537: Fix an assertion failure when an empty but presized dict
1609 object was stored in the freelist.
1610
Mark Dickinsonb6467572008-08-04 21:30:09 +00001611- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1612 ValueError consistently across platforms.
1613
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001614- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1615 (64bit Unix, for example), unichr() would truncate its argument and return
1616 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1617
Neal Norwitze7d8be82008-07-31 17:17:14 +00001618- Apply security patches from Apple.
1619
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001620- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1621 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1622
Antoine Pitrou92f82162008-07-25 22:22:08 +00001623- Issue #1819: function calls with several named parameters are now on
1624 average 35% faster (as measured by pybench).
1625
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001626- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1627 the python debugger steps into a class statement: the free variables (local
1628 variables defined in an outer scope) would be deleted from the outer scope.
1629
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001630- Issue #2620: Overflow checking when allocating or reallocating memory
1631 was not always being done properly in some python types and extension
1632 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1633 all been updated to perform better checks and places in the code that
1634 would previously leak memory on the error path when such an allocation
1635 failed have been fixed.

1639
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001640- Issue #3612: Added some missing basic types in ctypes.wintypes.
1641
Benjamin Petersone977ad42008-08-20 01:42:01 +00001642- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1643 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1644
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001645- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1646 version reported by these tools does not necessarily follow the python
1647 version numbering scheme, so the module is less strict when parsing it.
1648
Nick Coghlanf70385a2008-08-18 12:42:46 +00001649- Issue #2235: Added Py3k warnings for types which will become unhashable
1650 under the stricter __hash__ inheritance rules in 3.0. Several types
1651 which did not meet the rules for hash invariants and were already
1652 unhashable in 3.0 have now been explicitly flagged as unhashable in
1653 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1654 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1655
Brett Cannon88f801d2008-08-18 00:46:22 +00001656- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1657 imported into the module but exposed as part of the module's API.
1658
Brett Cannon7b96f072008-08-18 00:41:11 +00001659- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1660
Brett Cannon46225e72008-08-18 00:36:52 +00001661- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1662
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001663- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1664
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001665- Issue #3575: Incremental decoder's decode function now takes bytearray
1666 by using 's*' instead of 't#'.
1667
Jesus Cea585ad8a2009-07-02 15:37:21 +00001668- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001669 fails unicode conversion on 2nd parameter. (windows only)
1670
Facundo Batista94f243a2008-08-17 03:38:39 +00001671- Issue 2464. urllib2 now supports a malformation in the URL received
1672 in a redirect.
1673
Brett Cannonabe423e2008-08-16 21:47:07 +00001674- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001675 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001676
Facundo Batistaeb90b782008-08-16 14:44:07 +00001677- Issue #2776: fixed small issue when handling an URL with double slash
1678 after a 302 response in the case of not going through a proxy.
1679
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001680- Issue #2676: in the email package, content-type parsing was hanging on
1681 pathological input because of quadratic or exponential behaviour of a
1682 regular expression.
1683
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001684- Issue #3476: binary buffered reading through the new "io" library is now
1685 thread-safe.
1686
Brett Cannonbf3157b2008-08-14 05:00:03 +00001687- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1688 since mimetools itself is deprecated. Because modules are cached, all
1689 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1690
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001691- Issue #3134: shutil referenced undefined WindowsError symbol.
1692
Robert Schuppenies14646332008-08-10 11:01:53 +00001693- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1694 menu entries were not deleted.
1695
Brett Cannon83e81842008-08-09 23:30:55 +00001696- Copied the implementation of reduce() to _functools.reduce() to have a
1697 version that did not raise a DeprecationWarning under -3.
1698
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001699- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1700 a MemoryError rather than silently stop the iteration.
1701
Guido van Rossum59ce9012008-08-09 14:55:34 +00001702- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1703 to _sre.compile() will now be rejected. This should not affect anybody
1704 since the re.compile() function never generates invalid re-bytecode.
1705
Skip Montanaroa032bf42008-08-08 22:52:51 +00001706- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1707 upon first access it can be automatically initialized from the csv file if
1708 it wasn't initialized during instantiation.
1709
Brett Cannon3aa2a492008-08-06 22:28:09 +00001710- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1711 the reload() built-in has been removed.
1712
Brett Cannon7e30b672008-08-04 21:52:25 +00001713- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001714 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001721- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1722 raised an AttributeError.
1723
Benjamin Peterson01a24322008-07-28 23:35:27 +00001724- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001725 asking for a specific length. This problem only affected files opened
1726 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001727
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001728- Issue #3449: Update decimal module to use most recent specification
1729 (v. 1.68) and tests (v. 2.58) from IBM.
1730

1739
1740- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1741 invalid arguments.
1742
1743- Issue #3302: Fix several crashes when calling locale's gettext functions
1744 with None arguments.
1745
1746- Issue #3389: Allow resolving dotted names for handlers in logging
1747 configuration files.
1748
1749- Deprecate the sunaudio module for removal in Python 3.0.
1750
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001751- Issue #3394: zipfile.writestr sets external attributes when passed a
1752 file name rather than a ZipInfo instance, so files are extracted with
1753 mode 0600 rather than 000 under Unix.
1754
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001755- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1756 argument in python 2.5, this broke code that subclassed Popen to include its
1757 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1766
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001767- Issue #2235: the C API function PyObject_HashNotImplemented and its
1768 interaction with the tp_hash slot (added in 2.6b2) are now documented
1769
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001770- Issue #643841: The language reference now provides more detailed
1771 coverage of the lookup process for special methods. The disclaimers
1772 regarding lack of coverage of new-style classes have also been
1773 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001781Core and Builtins
1782-----------------
1783
Georg Brandl3e483f62008-07-16 22:57:41 +00001784- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1785 its methods now allow for items objects that can be converted to
1786 an integer using operator.index().
1787
Mark Dickinson64b7e502008-07-16 09:40:03 +00001788- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1789 produced a ValueError instead of giving the correct float.
1790
Eric Smitha5fa5a22008-07-16 00:11:49 +00001791- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1792 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1793
Mark Dickinson7103aa42008-07-15 19:08:33 +00001794- Issue #3008: the float type has a new instance method 'float.hex'
1795 and a new class method 'float.fromhex' to convert floating-point
1796 numbers to and from hexadecimal strings, respectively.
1797
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001798- Issue #2235: __hash__ is once again inherited by default. To allow
1799 collections.Hashable to remain meaningful in the presence of the
1800 default hash implementation (object.__hash__), it is now possible
1801 to explicit block inheritance of hash by setting __hash__=None at
1802 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1803 level.
1804
Nick Coghlanb028f502008-07-13 14:52:36 +00001805- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1806 the parent module cannot be found while performing an absolute import.
1807 This means that an incorrectly defined __package__ attribute will
1808 now only prevent relative imports in that module rather than causing
1809 all imports from that module to fail.
1810
Nick Coghlan14ff9942008-07-08 14:21:42 +00001811- Issue #2517: Allow unicode messages in Exceptions again by correctly
1812 bypassing the instance dictionary when looking up __unicode__ on
1813 new-style classes.
1814
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001815- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1816 set to a custom object whose write() method happens to install
1817 another file in sys.stdout.
1818
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001819- Issue #3088: Corrected a race condition in classes derived from
1820 threading.local: the first member set by a thread could be saved in
1821 another thread's dictionary.
1822
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001823- Issue #3004: Minor change to slice.indices(): the start and stop
1824 arguments are now treated identically, making the behaviour easier
1825 to describe and understand. For example, slice(None, -10,
1826 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1827 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1828 10, -1).
1829
Georg Brandl278fc502008-07-19 12:46:12 +00001830- Issue #3219: Calling a function with repeated keyword arguments,
1831 f(a=2, a=23), would not cause a syntax error. This was a regression
1832 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001833
Georg Brandl278fc502008-07-19 12:46:12 +00001834- Issue #2862: Make int and float freelist management consistent with
1835 other freelists. Changes their CompactFreeList apis into
1836 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001837

1840
Thomas Heller57adf222008-08-14 19:10:48 +00001841- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1842 api functions without holding the GIL, which could lead to a fatal
1843 error when they failed.
1844
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001845- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001853- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1854 ForkingPickler.register() to resolve conflict with ctypes.
1855
Vinay Sajip51e65192008-07-18 09:01:10 +00001856- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001857
Thomas Heller880f5292008-07-15 19:39:38 +00001858- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1859 a valid dlerror() message.
1860
Thomas Heller2bad6572008-07-15 17:19:50 +00001861- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1862 incomplete structure was created.
1863
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001864- Issue #3339: dummy_thread.acquire() should not return None.
1865
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001866- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1867
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001868- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001869
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001870- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1871 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001872 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001873 content-length. The problem had been corrected in the 2.4 branch, but never
1874 merged into trunk.
1875
Georg Brandle78fbcc2008-07-05 10:13:36 +00001876- Issue #2663: add filtering capability to shutil.copytree().

2281 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002282 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002283
2284 This is controlled by the configure argument ``--with-universal-archs``:
2285
2286 - ``--with-universal-archs=all``: install 4-way universal
2287
2288 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2289
2290 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2291
2292 This option should be used in combination with ``--enable-universalsdk=``.
2293
2294 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Issue #1631171: Re-implement the 'warnings' module in C (the
2345 original Python code has been kept as backup). This will allow for
2346 using the 'warning's machinery in such places as the parser where
2347 use of pure Python code is not possible. Both the ``showarning()``
2348 and ``formatwarning()`` gain an optional 'line' argument which is
2349 not called by default for backwards-compatibility reasons. Setting
2350 ``warnings.showwarning()`` to an implementation that lacks support
2351 for the ``line`` argument will raise a DeprecationWarning.

2375
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002376- The getpass module has been improved on Unix. It now uses /dev/tty
2377 by default and uses stderr instead of stdout. A GetPassWarning is
2378 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002414- Issue #2550: The approach used by client/server code for obtaining
2415 ports to listen on in network-oriented tests has been refined in an
2416 effort to facilitate running multiple instances of the entire
2417 regression test suite in parallel without issue.
2418 test_support.bind_port() has been fixed such that it will always
2419 return a unique port -- which wasn't always the case with the
2420 previous implementation, especially if socket options had been set
2421 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2422 new implementation of bind_port() will actually raise an exception
2423 if it is passed an AF_INET/SOCK_STREAM socket with either the
2424 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2425 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2426 the socket it's been passed. This currently only applies to
2427 Windows. This option prevents any other sockets from binding to the
2428 host/port we've bound to, thus removing the possibility of the
2429 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2430 when a second SOCK_STREAM socket binds and accepts to a host/port
2431 that's already been bound by another socket. The optional preferred
2432 port parameter to bind_port() has been removed. Under no
2433 circumstances should tests be hard coding ports!
2434
2435 test_support.find_unused_port() has also been introduced, which will
2436 pass a temporary socket object to bind_port() in order to obtain an
2437 unused port. The temporary socket object is then closed and
2438 deleted, and the port is returned. This method should only be used
2439 for obtaining an unused port in order to pass to an external program
2440 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2441 a parameter to a server-oriented class that doesn't give you direct
2442 access to the underlying socket used.

2720Core and builtins
2721-----------------
2722
Fred Drakea8ee94b2008-03-01 02:45:07 +00002723- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002724 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002725
Georg Brandlad61bc82008-02-23 15:11:18 +00002726- Issue #2067: file.__exit__() now calls subclasses' close() method.
2727
2728- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002729
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002730- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002731 issue 215555 for a discussion.
2732
Eric Smitha73fbe72008-02-23 03:09:44 +00002733- Added the future_builtins module, which contains hex() and oct().
2734 These are the PEP 3127 version of these functions, designed to be
2735 compatible with the hex() and oct() builtins from Python 3.0. They
2736 differ slightly in their output formats from the existing, unchanged
2737 Python 2.6 builtins. The expected usage of the future_builtins
2738 module is:
2739 from future_builtins import hex, oct
2740
Eric Smith7ef40bf2008-02-20 23:34:22 +00002741- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2742 exponents for exponents with absolute value < 100. Follows C99
2743 standard. This is a change on Windows, which would use 3 digits.
2744 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2745 so that any alterations it does to the resulting string will be
2746 available in stringlib/formatter.h (for float.__format__).
2747
Eric Smith5a3c1352008-02-19 13:21:56 +00002748- Implemented PEP 3101, Advanced String Formatting. This adds a new
2749 builtin format(); a format() method for str and unicode; a
2750 __format__() method to object, str, unicode, int, long, float, and
2751 datetime; the class string.Formatter; and the C API
2752 PyObject_Format().
2753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Fixed several potential crashes, all caused by specially crafted
2755 __del__ methods exploiting objects in temporarily inconsistent
2756 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002757
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002758- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759 prevent a possible crash: an Abstract Base Class would try to access
2760 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- Fixed repr() and str() of complex numbers with infinity or nan as
2763 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Clear all free lists during a gc.collect() of the highest generation
2766 in order to allow pymalloc to free more arenas. Python may give back
2767 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002768
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769- Issue #2045: Fix an infinite recursion triggered when printing a
2770 subclass of collections.defaultdict, if its default_factory is set
2771 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002772
Christian Heimesf75dbef2008-02-08 00:11:31 +00002773- Fixed a minor memory leak in dictobject.c. The content of the free
2774 list was not freed on interpreter shutdown.
2775
Georg Brandl3ee81df2008-05-17 18:14:43 +00002776- Limit free list of method and builtin function objects to 256
2777 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002778
Georg Brandl3ee81df2008-05-17 18:14:43 +00002779- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2780 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002781 to compact the internal free lists of pre-allocted ints and floats.
2782
Georg Brandl3ee81df2008-05-17 18:14:43 +00002783- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2784 calls. Python expected the return type int but the fork familie
2785 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2788 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002789
Georg Brandl3ee81df2008-05-17 18:14:43 +00002790- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2791 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002792
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2794 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2797 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002798
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- Patch #1473257: generator objects gain a gi_code attribute. This is
2800 the same object as the func_code attribute of the function that
2801 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002802
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803- Issue #1920: "while 0" statements were completely removed by the
2804 compiler, even in the presence of an "else" clause, which is
2805 supposed to be run when the condition is false. Now the compiler
2806 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002807
Guido van Rossumeead05f2008-01-24 18:21:02 +00002808- A few crashers fixed: weakref_in_del.py (issue #1377858);
2809 loosing_dict_ref.py (issue #1303614, test67.py);
2810 borrowed_ref_[34].py (not in tracker).
2811
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002812- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002813 suppressed while an extension is loaded by calling SetErrorMode in
2814 dynload_win.c. The error is still reported properly.
2815
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002817 several extension methods and modules do not work without unicode
2818 support.
2819
Georg Brandl26543b12008-01-21 18:36:51 +00002820- Issue #1882: when compiling code from a string, encoding cookies in the
2821 second line of code were not always recognized correctly.
2822
Georg Brandl14404b62008-01-19 19:27:05 +00002823- Issue #1679: "0x" was taken as a valid integer literal.
2824
Georg Brandl6caad7d2008-01-26 14:19:22 +00002825- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002826 added.
2827
Christian Heimesc94e2b52008-01-14 04:13:37 +00002828- sys.float_info / PyFloat_GetInfo: The floating point information
2829 object was converted from a dict to a specialized structseq object.
2830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Patch #1816: Added sys.flags structseq. It exposes the status of
2832 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002833
Georg Brandl3ee81df2008-05-17 18:14:43 +00002834- Objects/structseq.c: Implemented new structseq representation. The
2835 patch makes structseqs (e.g. the return value of os.stat) more
2836 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Patch #1700288: added a type attribute cache that caches method
2839 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002840
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002841- Bug #1776: __import__() no longer accepts filenames on any platform.
2842 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002843
Georg Brandlaed6c662008-01-07 17:25:53 +00002844- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2845
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2847 envvar and sys.dont_write_bytecode attribute. All these can be set
2848 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002849
Georg Brandl3ee81df2008-05-17 18:14:43 +00002850- Improve some exception messages when Windows fails to load an
2851 extension module. Now we get for example '%1 is not a valid Win32
2852 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002853
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2857 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002858
Christian Heimes0a8143f2007-12-18 23:22:54 +00002859- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860 and INF. float("nan"), float("inf") and float("-inf") now work on
2861 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Compiler now generates simpler and faster code for dictionary
2864 literals. The oparg for BUILD_MAP now indicates an estimated
2865 dictionary size. There is a new opcode, STORE_MAP, for adding
2866 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002867
Georg Brandl3ee81df2008-05-17 18:14:43 +00002868- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Issue #1620: New property decorator syntax was modifying the
2871 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002872
Georg Brandl3ee81df2008-05-17 18:14:43 +00002873- Issue #1538: Avoid copying string in split/rsplit if the split char
2874 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002876- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002877 SystemError.
2878
Nick Coghlanef01d822007-12-03 12:55:17 +00002879- PEP 366: Allow explicit relative imports when executing modules
2880 inside packages with the -m switch via a new module level
2881 __package__ attribute.
2882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Issue #1402: Fix a crash on exit, when another thread is still
2884 running, and if the deallocation of its frames somehow calls the
2885 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002886

2896 file can now be directly executed by passing their name to the
2897 interpreter. The directory/zipfile is automatically inserted as the
2898 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002899
Georg Brandl3ee81df2008-05-17 18:14:43 +00002900- Issue #1265: Fix a problem with sys.settrace, if the tracing
2901 function uses a generator expression when at the same time the
2902 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002903
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002904- sets and frozensets now have an isdisjoint() method.
2905
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002906- optimize the performance of builtin.sum().
2907
Neal Norwitz44f326e2007-10-05 05:29:17 +00002908- Fix warnings found by the new version of the Coverity checker.
2909
Georg Brandl3ee81df2008-05-17 18:14:43 +00002910- The enumerate() builtin function is no longer bounded to sequences
2911 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2912 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Issue #1686386: Tuple's tp_repr did not take into account the
2915 possibility of having a self-referential tuple, which is possible
2916 from C code. Nor did object's tp_str consider that a type's tp_str
2917 could do something that could lead to an inifinite recursion.
2918 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2919 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- Issue #1164: It was possible to trigger deadlock when using the
2922 'print' statement to write to a file since the GIL was not released
2923 as needed. Now PyObject_Print() does the right thing along with
2924 various tp_print implementations of the built-in types and those in
2925 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002926
Georg Brandl3ee81df2008-05-17 18:14:43 +00002927- Issue #1147: Exceptions were directly allowing string exceptions in
2928 their throw() method even though string exceptions no longer
2929 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002930
Georg Brandl3ee81df2008-05-17 18:14:43 +00002931- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002934- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002935 PyObject_Call() never calling back out to Python code to trigger
2936 recursion depth updates/checks. Required the creation of a static
2937 RuntimeError instance in case normalizing an exception put the
2938 recursion check value past its limit. Fixes crashers
2939 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002940

Neal Norwitz0ac60192007-05-27 04:08:54 +00002954- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955 __*__ attributes. (Some already existed, e.g., __doc__ and
2956 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002957
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002958- Add -3 option to the interpreter to warn about features that are

2963
Collin Winter62903052007-05-18 23:11:24 +00002964- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965 "except E as target:". This is to provide forwards compatibility
2966 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002967
Brett Cannon229cee22007-05-05 01:34:02 +00002968- Deprecate BaseException.message as per PEP 352.
2969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Issue #1303614: don't expose object's __dict__ when the dict is

2972
Vinay Sajip8549ce32007-05-06 17:53:37 +00002973- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002974 setting a plain string, ie don't expand to single letter identifiers.
2975
Raymond Hettinger13936692007-04-11 18:40:58 +00002976- Request #1191699: Slices can now be pickled.
2977
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002978- Request #1193128: str.translate() now allows a None argument for
2979 translations that only remove characters without re-mapping the
2980 remaining characters.
2981
Georg Brandl5cb76c12007-03-21 09:00:39 +00002982- Patch #1682205: a TypeError while unpacking an iterable is no longer

2986
Guido van Rossum143b5642007-03-23 04:58:42 +00002987- Bug #1683368: The object.__init__() and object.__new__() methods are
2988 now stricter in rejecting excess arguments. The only time when
2989 either allows excess arguments is when it is not overridden and the
2990 other one is. For backwards compatibility, when both are
2991 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002992 warning later). Also, type.__init__() insists on the same signature
2993 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2996 object to complex using its __complex__() method before falling back
2997 to the __float__() method. Therefore, the functions in the cmath
2998 module now can operate on objects that define a __complex__()
2999 method.

3003 same slot names.

3016
Georg Brandl7b9c5552007-03-12 14:30:05 +00003017- Bug #1678647: write a newline after printing an exception in any
3018 case, even when converting the value to a string failed.
3019
Georg Brandl871f1bc2007-03-12 13:17:36 +00003020- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021 its argument, if it exists. If not, it will work like before. This
3022 allows customizing the output of dir() in the presence of a
3023 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003024
Collin Winter276887b2007-03-12 16:11:39 +00003025- Patch #922167: Python no longer segfaults when faced with infinitely
3026 self-recursive reload() calls (as reported by bug #742342).
3027

3032 parthensized forms. This means complex(repr(x)) now works instead of
3033 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003034
Georg Brandlaa2321b2007-03-07 00:40:28 +00003035- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036 makes the filenames the warning module prints much more sensible
3037 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003038

Georg Brandl0fca97a2007-03-05 22:28:08 +00003050- Patch #1674228: when assigning a slice (old-style), check for the
3051 sq_ass_slice instead of the sq_slice slot.
3052
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053- When printing an unraisable error, don't print exceptions. before
3054 the name. This duplicates the behavior whening normally printing
3055 exceptions.

3064 created a weakref on itself during a __del__ call for new-style
3065 classes (classic classes still have the bug).

3678
Georg Brandl3ee81df2008-05-17 18:14:43 +00003679- unittest now verifies more of its assumptions. In particular,

3681 accepted in TestSuite.addTest(). This should cause no
3682 incompatibility since it never made sense with ordinary subclasses
3683 -- the failure just occurred later, with a more cumbersome
3684 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003965- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3966 with RFC 3207 and forgets any knowledge obtained from the server not
3967 obtained from the TLS negotiation itself. Patch contributed by Bill
3968 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003969
Georg Brandl3ee81df2008-05-17 18:14:43 +00003970- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003971 that the SMTP.starttls() caller no longer needs to call ehlo()
3972 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003973 does not claim to support starttls. Adds the
3974 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004029- itertools.chain() now has an alternate constructor,

4055 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4056 silently miscode subclasses of those types. Now, it raises a
4057 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004058

Georg Brandl3ee81df2008-05-17 18:14:43 +00004073 time so that opening a database previously created with the DB_DUP
4074 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4075 opens. Specifically: dictionary assignment to a DB object will
4076 replace all values for a given key when the database allows
4077 duplicate values. DB users should use DB.put(k, v) when they want
4078 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004079

4085 characters with ASCII value less than 32. Also, it correctly quotes
4086 dots only if they occur on a single line, as opposed to the previous
4087 behavior of quoting dots if they are the second character of any
4088 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004089

4412
Georg Brandl3ee81df2008-05-17 18:14:43 +00004413- Unified naming convention for free lists and their limits. All free
4414 lists in Object/ are named ``free_list``, the counter ``numfree``
4415 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4416 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004417
Georg Brandl3ee81df2008-05-17 18:14:43 +00004418- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4419 to ``PyTuple_SetItem``, it can be used to populate a brand new
4420 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004421
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004422- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004423
Georg Brandl3ee81df2008-05-17 18:14:43 +00004424- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4425 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4426 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004427
4428- Patch #1720595: add T_BOOL to the range of structmember types.
4429
4430- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4431 ``PyFloat_GetInfo()`` to the float API.
4432
Georg Brandl3ee81df2008-05-17 18:14:43 +00004433- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4434 of w# format code incorrectly truncated the length to an int, even
4435 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4436 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004437
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4439 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004440
Georg Brandl3ee81df2008-05-17 18:14:43 +00004441- PEP 3123: Provide forward compatibility with Python 3.0, while
4442 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4443 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004444
Georg Brandl3ee81df2008-05-17 18:14:43 +00004445- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4446 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004447
4448- Patch #1733960: Allow T_LONGLONG to accept ints.
4449
4450- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4451
Christian Heimes000a0742008-01-03 22:16:32 +00004452- Added a new API function ``PyImport_ImportModuleNoBlock``.
4453
Georg Brandl6caad7d2008-01-26 14:19:22 +00004454- Bug #1637022: Prefix AST symbols with _Py_.
4455
4456- Fix some leftovers from the conversion from int to Py_ssize_t
4457 (relevant to strings and sequences of more than 2**31 items).
4458
4459- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4460 outside of pystate.c and should not be necessary.
4461
Georg Brandl3ee81df2008-05-17 18:14:43 +00004462- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4463 absolute imports. In earlier versions they might have used relative
4464 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004465
Georg Brandl3ee81df2008-05-17 18:14:43 +00004466- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4467 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004468
Georg Brandl3ee81df2008-05-17 18:14:43 +00004469- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4470 macro so it can be used as an expression.

4475
Georg Brandl3ee81df2008-05-17 18:14:43 +00004476- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4477 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4478 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4479 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004480
Georg Brandl3ee81df2008-05-17 18:14:43 +00004481- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4482 _CRT_NONSTDC_NO_DEPRECATE.
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00004483
Martin v. Löwisd476a402007-10-12 08:56:52 +00004484- Bug #1216: Restore support for Visual Studio 2002.

Brett Cannon791d56f2007-05-31 19:40:42 +00004492- buildtools now raises a DeprecationWarning.
4493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Removed the macfs module. It had been deprecated since Python 2.5.
4495 This lead to the deprecation of macostools.touched() as it relied
4496 solely on macfs and was a no-op under OS X.
