663 output compared to previous Python versions.
664

667 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
668 partial bzip2 compressed data.
669
Benjamin Peterson373498f2009-03-22 17:49:21 +0000670- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

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

797 302 conformant loader) will now work correctly in most cases (they
798 are still subject to the constraints that exist for all code running
799 from inside a module loaded via a PEP 302 loader and attempting to

958What's New in Python 2.6.1
959==========================
960
961*Release date: 04-Dec-2008*
962
963Core and Builtins
964-----------------
965
966- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
967 interpreter to abort ("Fatal Python error: Could not reset the stack!")
968 instead of throwing a MemoryError.
969
970- Issue #4367: Python would segfault during compiling when the unicodedata
971 module couldn't be imported and \N escapes were present.
972
973- Issue #4348: Some bytearray methods returned that didn't cause any change to
974 the bytearray, returned the same bytearray instead of a copy.
975
976- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
977
978- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
979
980- Issue #4048: The parser module now correctly validates relative imports.
981
982- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
983 exec statement.
984
985- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
986 method does not return iterators for the 4th and 5th items.
987
988- Issue #4209: Enabling unicode_literals and the print_function in the same
989 __future__ import didn't work.
990
991- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
992 returned a path longer than MAX_PATH. (But It's doubtful this code path is
993 really executed because I cannot move to such directory on win2k)
994
995- Issue #4069: When set.remove(element) is used with a set element, the element
996 is temporarily replaced with an equivalent frozenset. But the eventual
997 KeyError would always report the empty frozenset([]) as the missing key. Now
998 it correctly refers to the initial element.
999
1000- Fixed C99 style comments in several files. Python is now C89 compatible
1001 again.

1149
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001150- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1151 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1152 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1153 ``printf`` function, whereas PyString_FromFormat has an independent
1154 implementation and uses "%zd" on all platforms for size_t values.
1155 This makes a difference on win64, where ``printf`` needs "%Id" to display
1156 64bit values.

1162 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001173 was correctly parsed but parsing of subsequent arguments failed.
1174
Vinay Sajip35e3b032008-09-01 14:33:59 +00001175- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001176 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1177 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1178 when given a tuple of classes as second argument, were looking up
1179 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1180 type object.

Martin v. Löwis67543a92008-09-08 12:02:45 +00001310- Allow passing the MSI file name to merge.py.
1311
Vinay Sajip844f7412008-09-09 13:42:08 +00001312- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001313 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001316What's New in Python 2.6 beta 3?
1317================================
1318
Barry Warsaw07a4a382008-08-21 01:15:08 +00001319*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001320
1321Core and Builtins
1322-----------------
1323
Guido van Rossumf8402962008-08-20 15:01:50 +00001324- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1325 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1326 extensions do not automatically benefit from the class attribute
1327 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1328 to their tp_flags field if they care. This is a backwards
1329 compatibility feature; in 3.0, all types will use the cache by
1330 default.
1331
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001332- Keyword arguments can now follow starred arguments. (``f(a, *args,
1333 keyword=23)`` is now valid syntax.)
1334
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001335- ctypes function pointers that are COM methods have a boolean True
1336 value again.
1337
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001338- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1339 by denying s# to parse objects that have a releasebuffer procedure,
1340 and introducing s*.
1341
Georg Brandl1e13ea92008-08-11 09:07:59 +00001342- Issue #3537: Fix an assertion failure when an empty but presized dict
1343 object was stored in the freelist.
1344
Mark Dickinsonb6467572008-08-04 21:30:09 +00001345- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1346 ValueError consistently across platforms.
1347
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001348- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1349 (64bit Unix, for example), unichr() would truncate its argument and return
1350 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1351
Neal Norwitze7d8be82008-07-31 17:17:14 +00001352- Apply security patches from Apple.
1353
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001354- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1355 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1356
Antoine Pitrou92f82162008-07-25 22:22:08 +00001357- Issue #1819: function calls with several named parameters are now on
1358 average 35% faster (as measured by pybench).
1359
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001360- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1361 the python debugger steps into a class statement: the free variables (local
1362 variables defined in an outer scope) would be deleted from the outer scope.
1363
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001364- Issue #2620: Overflow checking when allocating or reallocating memory
1365 was not always being done properly in some python types and extension
1366 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1367 all been updated to perform better checks and places in the code that
1368 would previously leak memory on the error path when such an allocation
1369 failed have been fixed.
1370
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001371Library
1372-------
1373
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001374- Issue #3612: Added some missing basic types in ctypes.wintypes.
1375
Benjamin Petersone977ad42008-08-20 01:42:01 +00001376- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1377 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1378
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001379- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1380 version reported by these tools does not necessarily follow the python
1381 version numbering scheme, so the module is less strict when parsing it.
1382
Nick Coghlanf70385a2008-08-18 12:42:46 +00001383- Issue #2235: Added Py3k warnings for types which will become unhashable
1384 under the stricter __hash__ inheritance rules in 3.0. Several types
1385 which did not meet the rules for hash invariants and were already
1386 unhashable in 3.0 have now been explicitly flagged as unhashable in
1387 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1388 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1389
Brett Cannon88f801d2008-08-18 00:46:22 +00001390- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1391 imported into the module but exposed as part of the module's API.
1392
Brett Cannon7b96f072008-08-18 00:41:11 +00001393- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1394
Brett Cannon46225e72008-08-18 00:36:52 +00001395- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1396
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001397- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1398
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001399- Issue #3575: Incremental decoder's decode function now takes bytearray
1400 by using 's*' instead of 't#'.
1401
Jesus Cea585ad8a2009-07-02 15:37:21 +00001402- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001403 fails unicode conversion on 2nd parameter. (windows only)
1404
Facundo Batista94f243a2008-08-17 03:38:39 +00001405- Issue 2464. urllib2 now supports a malformation in the URL received
1406 in a redirect.
1407
Brett Cannonabe423e2008-08-16 21:47:07 +00001408- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001409 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001410
Facundo Batistaeb90b782008-08-16 14:44:07 +00001411- Issue #2776: fixed small issue when handling an URL with double slash
1412 after a 302 response in the case of not going through a proxy.
1413
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001414- Issue #2676: in the email package, content-type parsing was hanging on
1415 pathological input because of quadratic or exponential behaviour of a
1416 regular expression.
1417
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001418- Issue #3476: binary buffered reading through the new "io" library is now
1419 thread-safe.
1420
Brett Cannonbf3157b2008-08-14 05:00:03 +00001421- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1422 since mimetools itself is deprecated. Because modules are cached, all
1423 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1424
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001425- Issue #3134: shutil referenced undefined WindowsError symbol.
1426
Robert Schuppenies14646332008-08-10 11:01:53 +00001427- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1428 menu entries were not deleted.
1429
Brett Cannon83e81842008-08-09 23:30:55 +00001430- Copied the implementation of reduce() to _functools.reduce() to have a
1431 version that did not raise a DeprecationWarning under -3.
1432
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001433- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1434 a MemoryError rather than silently stop the iteration.
1435
Guido van Rossum59ce9012008-08-09 14:55:34 +00001436- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1437 to _sre.compile() will now be rejected. This should not affect anybody
1438 since the re.compile() function never generates invalid re-bytecode.
1439
Skip Montanaroa032bf42008-08-08 22:52:51 +00001440- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1441 upon first access it can be automatically initialized from the csv file if
1442 it wasn't initialized during instantiation.
1443
Brett Cannon3aa2a492008-08-06 22:28:09 +00001444- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1445 the reload() built-in has been removed.
1446
Brett Cannon7e30b672008-08-04 21:52:25 +00001447- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001448 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1450 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1451 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1452 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1453 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001454
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001455- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1456 raised an AttributeError.
1457
Benjamin Peterson01a24322008-07-28 23:35:27 +00001458- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001459 asking for a specific length. This problem only affected files opened
1460 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001461
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001462- Issue #3449: Update decimal module to use most recent specification
1463 (v. 1.68) and tests (v. 2.58) from IBM.
1464
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001465- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1466

1473
1474- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1475 invalid arguments.
1476
1477- Issue #3302: Fix several crashes when calling locale's gettext functions
1478 with None arguments.
1479
1480- Issue #3389: Allow resolving dotted names for handlers in logging
1481 configuration files.
1482
1483- Deprecate the sunaudio module for removal in Python 3.0.
1484
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001485- Issue #3394: zipfile.writestr sets external attributes when passed a
1486 file name rather than a ZipInfo instance, so files are extracted with
1487 mode 0600 rather than 000 under Unix.
1488
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001489- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1490 argument in python 2.5, this broke code that subclassed Popen to include its
1491 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1499-------------
1500
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001501- Issue #2235: the C API function PyObject_HashNotImplemented and its
1502 interaction with the tp_hash slot (added in 2.6b2) are now documented
1503
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001504- Issue #643841: The language reference now provides more detailed
1505 coverage of the lookup process for special methods. The disclaimers
1506 regarding lack of coverage of new-style classes have also been
1507 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001510What's New in Python 2.6 beta 2?
1511================================
1512
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001513*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001515Core and Builtins
1516-----------------
1517
Georg Brandl3e483f62008-07-16 22:57:41 +00001518- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1519 its methods now allow for items objects that can be converted to
1520 an integer using operator.index().
1521
Mark Dickinson64b7e502008-07-16 09:40:03 +00001522- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1523 produced a ValueError instead of giving the correct float.
1524
Eric Smitha5fa5a22008-07-16 00:11:49 +00001525- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1526 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1527
Mark Dickinson7103aa42008-07-15 19:08:33 +00001528- Issue #3008: the float type has a new instance method 'float.hex'
1529 and a new class method 'float.fromhex' to convert floating-point
1530 numbers to and from hexadecimal strings, respectively.
1531
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001532- Issue #2235: __hash__ is once again inherited by default. To allow
1533 collections.Hashable to remain meaningful in the presence of the
1534 default hash implementation (object.__hash__), it is now possible
1535 to explicit block inheritance of hash by setting __hash__=None at
1536 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1537 level.
1538
Nick Coghlanb028f502008-07-13 14:52:36 +00001539- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1540 the parent module cannot be found while performing an absolute import.
1541 This means that an incorrectly defined __package__ attribute will
1542 now only prevent relative imports in that module rather than causing
1543 all imports from that module to fail.
1544
Nick Coghlan14ff9942008-07-08 14:21:42 +00001545- Issue #2517: Allow unicode messages in Exceptions again by correctly
1546 bypassing the instance dictionary when looking up __unicode__ on
1547 new-style classes.
1548
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001549- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1550 set to a custom object whose write() method happens to install
1551 another file in sys.stdout.
1552
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001553- Issue #3088: Corrected a race condition in classes derived from
1554 threading.local: the first member set by a thread could be saved in
1555 another thread's dictionary.
1556
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001557- Issue #3004: Minor change to slice.indices(): the start and stop
1558 arguments are now treated identically, making the behaviour easier
1559 to describe and understand. For example, slice(None, -10,
1560 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1561 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1562 10, -1).
1563
Georg Brandl278fc502008-07-19 12:46:12 +00001564- Issue #3219: Calling a function with repeated keyword arguments,
1565 f(a=2, a=23), would not cause a syntax error. This was a regression
1566 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001567
Georg Brandl278fc502008-07-19 12:46:12 +00001568- Issue #2862: Make int and float freelist management consistent with
1569 other freelists. Changes their CompactFreeList apis into
1570 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001571

1574
Thomas Heller57adf222008-08-14 19:10:48 +00001575- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1576 api functions without holding the GIL, which could lead to a fatal
1577 error when they failed.
1578
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001579- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001587- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1588 ForkingPickler.register() to resolve conflict with ctypes.
1589
Vinay Sajip51e65192008-07-18 09:01:10 +00001590- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

1593 a valid dlerror() message.
1594
Thomas Heller2bad6572008-07-15 17:19:50 +00001595- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1596 incomplete structure was created.
1597
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001598- Issue #3339: dummy_thread.acquire() should not return None.
1599

Georg Brandl5cc774e2008-06-11 20:28:06 +00002016 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002017
2018 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00002078- Issue #1631171: Re-implement the 'warnings' module in C (the
2079 original Python code has been kept as backup). This will allow for
2080 using the 'warning's machinery in such places as the parser where
2081 use of pure Python code is not possible. Both the ``showarning()``
2082 and ``formatwarning()`` gain an optional 'line' argument which is
2083 not called by default for backwards-compatibility reasons. Setting
2084 ``warnings.showwarning()`` to an implementation that lacks support
2085 for the ``line`` argument will raise a DeprecationWarning.

2109
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002110- The getpass module has been improved on Unix. It now uses /dev/tty
2111 by default and uses stderr instead of stdout. A GetPassWarning is
2112 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002127- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002128 extension modules between 32 and 64 bit platforms. See the distutls

2150 effort to facilitate running multiple instances of the entire
2151 regression test suite in parallel without issue.
2152 test_support.bind_port() has been fixed such that it will always
2153 return a unique port -- which wasn't always the case with the
2154 previous implementation, especially if socket options had been set
2155 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2156 new implementation of bind_port() will actually raise an exception
2157 if it is passed an AF_INET/SOCK_STREAM socket with either the
2158 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2159 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2160 the socket it's been passed. This currently only applies to
2161 Windows. This option prevents any other sockets from binding to the
2162 host/port we've bound to, thus removing the possibility of the
2163 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2164 when a second SOCK_STREAM socket binds and accepts to a host/port
2165 that's already been bound by another socket. The optional preferred
2166 port parameter to bind_port() has been removed. Under no
2167 circumstances should tests be hard coding ports!
2168
2169 test_support.find_unused_port() has also been introduced, which will
2170 pass a temporary socket object to bind_port() in order to obtain an
2171 unused port. The temporary socket object is then closed and
2172 deleted, and the port is returned. This method should only be used
2173 for obtaining an unused port in order to pass to an external program
2174 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2175 a parameter to a server-oriented class that doesn't give you direct
2176 access to the underlying socket used.
2177
2178 Finally, test_support.HOST has been introduced, which should be used
2179 for the host argument of any relevant socket calls (i.e. bind and
2180 connect).

2182 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002183 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002184 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2185 test_asynchat and test_socket_ssl.
2186
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187 It is now possible for multiple instances of the regression test
2188 suite to run in parallel without issue.

2454Core and builtins
2455-----------------
2456
Fred Drakea8ee94b2008-03-01 02:45:07 +00002457- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002458 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002459
Georg Brandlad61bc82008-02-23 15:11:18 +00002460- Issue #2067: file.__exit__() now calls subclasses' close() method.
2461
2462- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002463
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002464- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002465 issue 215555 for a discussion.
2466
Eric Smitha73fbe72008-02-23 03:09:44 +00002467- Added the future_builtins module, which contains hex() and oct().
2468 These are the PEP 3127 version of these functions, designed to be
2469 compatible with the hex() and oct() builtins from Python 3.0. They
2470 differ slightly in their output formats from the existing, unchanged
2471 Python 2.6 builtins. The expected usage of the future_builtins
2472 module is:
2473 from future_builtins import hex, oct
2474
Eric Smith7ef40bf2008-02-20 23:34:22 +00002475- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2476 exponents for exponents with absolute value < 100. Follows C99
2477 standard. This is a change on Windows, which would use 3 digits.
2478 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2479 so that any alterations it does to the resulting string will be
2480 available in stringlib/formatter.h (for float.__format__).
2481
Eric Smith5a3c1352008-02-19 13:21:56 +00002482- Implemented PEP 3101, Advanced String Formatting. This adds a new
2483 builtin format(); a format() method for str and unicode; a
2484 __format__() method to object, str, unicode, int, long, float, and
2485 datetime; the class string.Formatter; and the C API
2486 PyObject_Format().
2487
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488- Fixed several potential crashes, all caused by specially crafted
2489 __del__ methods exploiting objects in temporarily inconsistent
2490 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002491
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002492- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493 prevent a possible crash: an Abstract Base Class would try to access
2494 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002495
Georg Brandl3ee81df2008-05-17 18:14:43 +00002496- Fixed repr() and str() of complex numbers with infinity or nan as
2497 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002498
Georg Brandl3ee81df2008-05-17 18:14:43 +00002499- Clear all free lists during a gc.collect() of the highest generation
2500 in order to allow pymalloc to free more arenas. Python may give back
2501 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002502
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503- Issue #2045: Fix an infinite recursion triggered when printing a
2504 subclass of collections.defaultdict, if its default_factory is set
2505 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002506
Christian Heimesf75dbef2008-02-08 00:11:31 +00002507- Fixed a minor memory leak in dictobject.c. The content of the free
2508 list was not freed on interpreter shutdown.
2509
Georg Brandl3ee81df2008-05-17 18:14:43 +00002510- Limit free list of method and builtin function objects to 256
2511 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002512
Georg Brandl3ee81df2008-05-17 18:14:43 +00002513- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2514 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002515 to compact the internal free lists of pre-allocted ints and floats.
2516
Georg Brandl3ee81df2008-05-17 18:14:43 +00002517- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2518 calls. Python expected the return type int but the fork familie
2519 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002520
Georg Brandl3ee81df2008-05-17 18:14:43 +00002521- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2522 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002523
Georg Brandl3ee81df2008-05-17 18:14:43 +00002524- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2525 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002526
Georg Brandl3ee81df2008-05-17 18:14:43 +00002527- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2528 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2531 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002532
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533- Patch #1473257: generator objects gain a gi_code attribute. This is
2534 the same object as the func_code attribute of the function that
2535 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002536
Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Issue #1920: "while 0" statements were completely removed by the
2538 compiler, even in the presence of an "else" clause, which is
2539 supposed to be run when the condition is false. Now the compiler
2540 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002541
Guido van Rossumeead05f2008-01-24 18:21:02 +00002542- A few crashers fixed: weakref_in_del.py (issue #1377858);
2543 loosing_dict_ref.py (issue #1303614, test67.py);
2544 borrowed_ref_[34].py (not in tracker).
2545
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002546- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002547 suppressed while an extension is loaded by calling SetErrorMode in
2548 dynload_win.c. The error is still reported properly.
2549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002551 several extension methods and modules do not work without unicode
2552 support.
2553
Georg Brandl26543b12008-01-21 18:36:51 +00002554- Issue #1882: when compiling code from a string, encoding cookies in the
2555 second line of code were not always recognized correctly.
2556
Georg Brandl14404b62008-01-19 19:27:05 +00002557- Issue #1679: "0x" was taken as a valid integer literal.
2558
Georg Brandl6caad7d2008-01-26 14:19:22 +00002559- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002560 added.
2561
Christian Heimesc94e2b52008-01-14 04:13:37 +00002562- sys.float_info / PyFloat_GetInfo: The floating point information
2563 object was converted from a dict to a specialized structseq object.
2564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Patch #1816: Added sys.flags structseq. It exposes the status of
2566 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002567
Georg Brandl3ee81df2008-05-17 18:14:43 +00002568- Objects/structseq.c: Implemented new structseq representation. The
2569 patch makes structseqs (e.g. the return value of os.stat) more
2570 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Patch #1700288: added a type attribute cache that caches method
2573 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002574
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002575- Bug #1776: __import__() no longer accepts filenames on any platform.
2576 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002577
Georg Brandlaed6c662008-01-07 17:25:53 +00002578- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2581 envvar and sys.dont_write_bytecode attribute. All these can be set
2582 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002583
Georg Brandl3ee81df2008-05-17 18:14:43 +00002584- Improve some exception messages when Windows fails to load an
2585 extension module. Now we get for example '%1 is not a valid Win32
2586 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002587
Georg Brandl3ee81df2008-05-17 18:14:43 +00002588- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2591 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002592
Christian Heimes0a8143f2007-12-18 23:22:54 +00002593- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002594 and INF. float("nan"), float("inf") and float("-inf") now work on
2595 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002596
Georg Brandl3ee81df2008-05-17 18:14:43 +00002597- Compiler now generates simpler and faster code for dictionary
2598 literals. The oparg for BUILD_MAP now indicates an estimated
2599 dictionary size. There is a new opcode, STORE_MAP, for adding
2600 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002604- Issue #1620: New property decorator syntax was modifying the
2605 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Issue #1538: Avoid copying string in split/rsplit if the split char
2608 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002610- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002611 SystemError.
2612
Nick Coghlanef01d822007-12-03 12:55:17 +00002613- PEP 366: Allow explicit relative imports when executing modules
2614 inside packages with the -m switch via a new module level
2615 __package__ attribute.
2616
Georg Brandl3ee81df2008-05-17 18:14:43 +00002617- Issue #1402: Fix a crash on exit, when another thread is still
2618 running, and if the deallocation of its frames somehow calls the
2619 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002620

2630 file can now be directly executed by passing their name to the
2631 interpreter. The directory/zipfile is automatically inserted as the
2632 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002633
Georg Brandl3ee81df2008-05-17 18:14:43 +00002634- Issue #1265: Fix a problem with sys.settrace, if the tracing
2635 function uses a generator expression when at the same time the
2636 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002637
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002638- sets and frozensets now have an isdisjoint() method.
2639
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002640- optimize the performance of builtin.sum().
2641
Neal Norwitz44f326e2007-10-05 05:29:17 +00002642- Fix warnings found by the new version of the Coverity checker.
2643
Georg Brandl3ee81df2008-05-17 18:14:43 +00002644- The enumerate() builtin function is no longer bounded to sequences
2645 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2646 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002647
Georg Brandl3ee81df2008-05-17 18:14:43 +00002648- Issue #1686386: Tuple's tp_repr did not take into account the
2649 possibility of having a self-referential tuple, which is possible
2650 from C code. Nor did object's tp_str consider that a type's tp_str
2651 could do something that could lead to an inifinite recursion.
2652 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2653 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002654
Georg Brandl3ee81df2008-05-17 18:14:43 +00002655- Issue #1164: It was possible to trigger deadlock when using the
2656 'print' statement to write to a file since the GIL was not released
2657 as needed. Now PyObject_Print() does the right thing along with
2658 various tp_print implementations of the built-in types and those in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002661- Issue #1147: Exceptions were directly allowing string exceptions in
2662 their throw() method even though string exceptions no longer
2663 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002664
Georg Brandl3ee81df2008-05-17 18:14:43 +00002665- Issue #1096: Prevent a segfault from getting the repr of a very
2666 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002667
Brett Cannon1e534b52007-09-07 04:18:30 +00002668- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002669 PyObject_Call() never calling back out to Python code to trigger
2670 recursion depth updates/checks. Required the creation of a static
2671 RuntimeError instance in case normalizing an exception put the
2672 recursion check value past its limit. Fixes crashers
2673 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002688- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689 __*__ attributes. (Some already existed, e.g., __doc__ and
2690 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002691
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002692- Add -3 option to the interpreter to warn about features that are

2696 calls.
2697
Collin Winter62903052007-05-18 23:11:24 +00002698- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699 "except E as target:". This is to provide forwards compatibility
2700 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002701
Brett Cannon229cee22007-05-05 01:34:02 +00002702- Deprecate BaseException.message as per PEP 352.
2703
Georg Brandl3ee81df2008-05-17 18:14:43 +00002704- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002705 inherited from a builtin base.
2706
Vinay Sajip8549ce32007-05-06 17:53:37 +00002707- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002708 setting a plain string, ie don't expand to single letter identifiers.
2709
Raymond Hettinger13936692007-04-11 18:40:58 +00002710- Request #1191699: Slices can now be pickled.
2711
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002712- Request #1193128: str.translate() now allows a None argument for
2713 translations that only remove characters without re-mapping the
2714 remaining characters.
2715
Georg Brandl5cb76c12007-03-21 09:00:39 +00002716- Patch #1682205: a TypeError while unpacking an iterable is no longer

2720
Guido van Rossum143b5642007-03-23 04:58:42 +00002721- Bug #1683368: The object.__init__() and object.__new__() methods are
2722 now stricter in rejecting excess arguments. The only time when
2723 either allows excess arguments is when it is not overridden and the
2724 other one is. For backwards compatibility, when both are
2725 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002726 warning later). Also, type.__init__() insists on the same signature
2727 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002728
Georg Brandl3ee81df2008-05-17 18:14:43 +00002729- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2730 object to complex using its __complex__() method before falling back
2731 to the __float__() method. Therefore, the functions in the cmath
2732 module now can operate on objects that define a __complex__()
2733 method.

2744 its type.

2750
Georg Brandl7b9c5552007-03-12 14:30:05 +00002751- Bug #1678647: write a newline after printing an exception in any
2752 case, even when converting the value to a string failed.
2753
Georg Brandl871f1bc2007-03-12 13:17:36 +00002754- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755 its argument, if it exists. If not, it will work like before. This
2756 allows customizing the output of dir() in the presence of a
2757 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002758
Collin Winter276887b2007-03-12 16:11:39 +00002759- Patch #922167: Python no longer segfaults when faced with infinitely
2760 self-recursive reload() calls (as reported by bug #742342).

2766 parthensized forms. This means complex(repr(x)) now works instead of
2767 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002768
Georg Brandlaa2321b2007-03-07 00:40:28 +00002769- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002770 makes the filenames the warning module prints much more sensible
2771 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002772

Georg Brandl0fca97a2007-03-05 22:28:08 +00002784- Patch #1674228: when assigning a slice (old-style), check for the
2785 sq_ass_slice instead of the sq_slice slot.
2786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- When printing an unraisable error, don't print exceptions. before
2788 the name. This duplicates the behavior whening normally printing
2789 exceptions.

2798 created a weakref on itself during a __del__ call for new-style
2799 classes (classic classes still have the bug).

3398 Python would crash instead of raising an error.
3399
Thomas Hellerc2f77252007-03-09 19:21:28 +00003400- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
3401 returned string up to the first NUL character.

3412
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- unittest now verifies more of its assumptions. In particular,
3414 TestCase and TestSuite subclasses (not instances) are no longer
3415 accepted in TestSuite.addTest(). This should cause no
3416 incompatibility since it never made sense with ordinary subclasses
3417 -- the failure just occurred later, with a more cumbersome
3418 exception.

3701 obtained from the TLS negotiation itself. Patch contributed by Bill
3702 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003703
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003705 that the SMTP.starttls() caller no longer needs to call ehlo()
3706 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707 does not claim to support starttls. Adds the
3708 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3789 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3790 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003807 time so that opening a database previously created with the DB_DUP
3808 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3809 opens. Specifically: dictionary assignment to a DB object will
3810 replace all values for a given key when the database allows
3811 duplicate values. DB users should use DB.put(k, v) when they want
3812 to store duplicates; not DB[k] = v.

3819 characters with ASCII value less than 32. Also, it correctly quotes
3820 dots only if they occur on a single line, as opposed to the previous
3821 behavior of quoting dots if they are the second character of any
3822 line.

4145-----
4146
Georg Brandl3ee81df2008-05-17 18:14:43 +00004147- Unified naming convention for free lists and their limits. All free
4148 lists in Object/ are named ``free_list``, the counter ``numfree``
4149 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4150 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4153 to ``PyTuple_SetItem``, it can be used to populate a brand new
4154 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004155
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004156- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4159 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4160 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004161
4162- Patch #1720595: add T_BOOL to the range of structmember types.
4163
4164- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4165 ``PyFloat_GetInfo()`` to the float API.
4166
Georg Brandl3ee81df2008-05-17 18:14:43 +00004167- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4168 of w# format code incorrectly truncated the length to an int, even
4169 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4170 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4173 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- PEP 3123: Provide forward compatibility with Python 3.0, while
4176 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4177 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004178
Georg Brandl3ee81df2008-05-17 18:14:43 +00004179- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4180 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004181
4182- Patch #1733960: Allow T_LONGLONG to accept ints.

4189
4190- Fix some leftovers from the conversion from int to Py_ssize_t
4191 (relevant to strings and sequences of more than 2**31 items).
4192
4193- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4194 outside of pystate.c and should not be necessary.
4195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4197 absolute imports. In earlier versions they might have used relative
4198 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4201 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4211 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4212 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4213 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004214
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- Removed the macfs module. It had been deprecated since Python 2.5.
4229 This lead to the deprecation of macostools.touched() as it relied
4230 solely on macfs and was a no-op under OS X.
