737 do an explicit seek to the end of file (so that e.g. tell() returns the

739 traditional 2.x file object.

935What's New in Python 2.6.1
936==========================
937
938*Release date: 04-Dec-2008*
939
940Core and Builtins
941-----------------
942
943- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
944 interpreter to abort ("Fatal Python error: Could not reset the stack!")
945 instead of throwing a MemoryError.
946
947- Issue #4367: Python would segfault during compiling when the unicodedata
948 module couldn't be imported and \N escapes were present.
949
950- Issue #4348: Some bytearray methods returned that didn't cause any change to
951 the bytearray, returned the same bytearray instead of a copy.
952
953- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
954
955- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
956
957- Issue #4048: The parser module now correctly validates relative imports.
958
959- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
960 exec statement.
961
962- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
963 method does not return iterators for the 4th and 5th items.
964
965- Issue #4209: Enabling unicode_literals and the print_function in the same
966 __future__ import didn't work.
967
968- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
969 returned a path longer than MAX_PATH. (But It's doubtful this code path is
970 really executed because I cannot move to such directory on win2k)
971
972- Issue #4069: When set.remove(element) is used with a set element, the element
973 is temporarily replaced with an equivalent frozenset. But the eventual
974 KeyError would always report the empty frozenset([]) as the missing key. Now
975 it correctly refers to the initial element.
976
977- Fixed C99 style comments in several files. Python is now C89 compatible
978 again.
979

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001125- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1126
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001127- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1128 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1129 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1130 ``printf`` function, whereas PyString_FromFormat has an independent
1131 implementation and uses "%zd" on all platforms for size_t values.
1132 This makes a difference on win64, where ``printf`` needs "%Id" to display
1133 64bit values.

1139 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001150 was correctly parsed but parsing of subsequent arguments failed.
1151
Vinay Sajip35e3b032008-09-01 14:33:59 +00001152- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001153 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1154 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1155 when given a tuple of classes as second argument, were looking up
1156 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1157 type object.

1304 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1305 to their tp_flags field if they care. This is a backwards
1306 compatibility feature; in 3.0, all types will use the cache by
1307 default.
1308
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001309- Keyword arguments can now follow starred arguments. (``f(a, *args,
1310 keyword=23)`` is now valid syntax.)
1311
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001312- ctypes function pointers that are COM methods have a boolean True
1313 value again.
1314
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001315- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1316 by denying s# to parse objects that have a releasebuffer procedure,
1317 and introducing s*.
1318
Georg Brandl1e13ea92008-08-11 09:07:59 +00001319- Issue #3537: Fix an assertion failure when an empty but presized dict
1320 object was stored in the freelist.
1321
Mark Dickinsonb6467572008-08-04 21:30:09 +00001322- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1323 ValueError consistently across platforms.
1324
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001325- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1326 (64bit Unix, for example), unichr() would truncate its argument and return
1327 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1328
Neal Norwitze7d8be82008-07-31 17:17:14 +00001329- Apply security patches from Apple.
1330
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001331- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1332 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1333
Antoine Pitrou92f82162008-07-25 22:22:08 +00001334- Issue #1819: function calls with several named parameters are now on
1335 average 35% faster (as measured by pybench).
1336
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001337- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1338 the python debugger steps into a class statement: the free variables (local
1339 variables defined in an outer scope) would be deleted from the outer scope.
1340
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001341- Issue #2620: Overflow checking when allocating or reallocating memory
1342 was not always being done properly in some python types and extension
1343 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1344 all been updated to perform better checks and places in the code that
1345 would previously leak memory on the error path when such an allocation
1346 failed have been fixed.

1352
Benjamin Petersone977ad42008-08-20 01:42:01 +00001353- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1354 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1355
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001356- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1357 version reported by these tools does not necessarily follow the python
1358 version numbering scheme, so the module is less strict when parsing it.
1359
Nick Coghlanf70385a2008-08-18 12:42:46 +00001360- Issue #2235: Added Py3k warnings for types which will become unhashable
1361 under the stricter __hash__ inheritance rules in 3.0. Several types
1362 which did not meet the rules for hash invariants and were already
1363 unhashable in 3.0 have now been explicitly flagged as unhashable in
1364 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1365 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1366
Brett Cannon88f801d2008-08-18 00:46:22 +00001367- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1368 imported into the module but exposed as part of the module's API.
1369
Brett Cannon7b96f072008-08-18 00:41:11 +00001370- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1371
Brett Cannon46225e72008-08-18 00:36:52 +00001372- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1375
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001376- Issue #3575: Incremental decoder's decode function now takes bytearray
1377 by using 's*' instead of 't#'.
1378
Jesus Cea585ad8a2009-07-02 15:37:21 +00001379- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001380 fails unicode conversion on 2nd parameter. (windows only)
1381
Facundo Batista94f243a2008-08-17 03:38:39 +00001382- Issue 2464. urllib2 now supports a malformation in the URL received
1383 in a redirect.
1384
Brett Cannonabe423e2008-08-16 21:47:07 +00001385- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001386 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001387
Facundo Batistaeb90b782008-08-16 14:44:07 +00001388- Issue #2776: fixed small issue when handling an URL with double slash
1389 after a 302 response in the case of not going through a proxy.
1390
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001391- Issue #2676: in the email package, content-type parsing was hanging on
1392 pathological input because of quadratic or exponential behaviour of a
1393 regular expression.
1394
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001395- Issue #3476: binary buffered reading through the new "io" library is now
1396 thread-safe.
1397
Brett Cannonbf3157b2008-08-14 05:00:03 +00001398- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1399 since mimetools itself is deprecated. Because modules are cached, all
1400 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1401
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001402- Issue #3134: shutil referenced undefined WindowsError symbol.
1403
Robert Schuppenies14646332008-08-10 11:01:53 +00001404- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1405 menu entries were not deleted.
1406
Brett Cannon83e81842008-08-09 23:30:55 +00001407- Copied the implementation of reduce() to _functools.reduce() to have a
1408 version that did not raise a DeprecationWarning under -3.
1409
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001410- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1411 a MemoryError rather than silently stop the iteration.
1412
Guido van Rossum59ce9012008-08-09 14:55:34 +00001413- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1414 to _sre.compile() will now be rejected. This should not affect anybody
1415 since the re.compile() function never generates invalid re-bytecode.
1416
Skip Montanaroa032bf42008-08-08 22:52:51 +00001417- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1418 upon first access it can be automatically initialized from the csv file if
1419 it wasn't initialized during instantiation.
1420
Brett Cannon3aa2a492008-08-06 22:28:09 +00001421- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1422 the reload() built-in has been removed.
1423
Brett Cannon7e30b672008-08-04 21:52:25 +00001424- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001425 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1433 raised an AttributeError.
1434
Benjamin Peterson01a24322008-07-28 23:35:27 +00001435- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001436 asking for a specific length. This problem only affected files opened
1437 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001438
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001439- Issue #3449: Update decimal module to use most recent specification
1440 (v. 1.68) and tests (v. 2.58) from IBM.
1441

1450
1451- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1452 invalid arguments.
1453
1454- Issue #3302: Fix several crashes when calling locale's gettext functions
1455 with None arguments.
1456
1457- Issue #3389: Allow resolving dotted names for handlers in logging
1458 configuration files.
1459
1460- Deprecate the sunaudio module for removal in Python 3.0.
1461
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001462- Issue #3394: zipfile.writestr sets external attributes when passed a
1463 file name rather than a ZipInfo instance, so files are extracted with
1464 mode 0600 rather than 000 under Unix.
1465
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001466- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1467 argument in python 2.5, this broke code that subclassed Popen to include its
1468 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1476-------------
1477
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001478- Issue #2235: the C API function PyObject_HashNotImplemented and its
1479 interaction with the tp_hash slot (added in 2.6b2) are now documented
1480
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001481- Issue #643841: The language reference now provides more detailed
1482 coverage of the lookup process for special methods. The disclaimers
1483 regarding lack of coverage of new-style classes have also been
1484 removed, since the coverage is now fairly reasonable.

1488================================
1489
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001490*Release date: 17-Jul-2008*
1491
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001492Core and Builtins
1493-----------------
1494
Georg Brandl3e483f62008-07-16 22:57:41 +00001495- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1496 its methods now allow for items objects that can be converted to
1497 an integer using operator.index().
1498
Mark Dickinson64b7e502008-07-16 09:40:03 +00001499- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1500 produced a ValueError instead of giving the correct float.
1501
Eric Smitha5fa5a22008-07-16 00:11:49 +00001502- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1503 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1504
Mark Dickinson7103aa42008-07-15 19:08:33 +00001505- Issue #3008: the float type has a new instance method 'float.hex'
1506 and a new class method 'float.fromhex' to convert floating-point
1507 numbers to and from hexadecimal strings, respectively.
1508
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001509- Issue #2235: __hash__ is once again inherited by default. To allow
1510 collections.Hashable to remain meaningful in the presence of the
1511 default hash implementation (object.__hash__), it is now possible
1512 to explicit block inheritance of hash by setting __hash__=None at
1513 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1514 level.
1515
Nick Coghlanb028f502008-07-13 14:52:36 +00001516- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1517 the parent module cannot be found while performing an absolute import.
1518 This means that an incorrectly defined __package__ attribute will
1519 now only prevent relative imports in that module rather than causing
1520 all imports from that module to fail.
1521
Nick Coghlan14ff9942008-07-08 14:21:42 +00001522- Issue #2517: Allow unicode messages in Exceptions again by correctly
1523 bypassing the instance dictionary when looking up __unicode__ on
1524 new-style classes.
1525
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001526- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1527 set to a custom object whose write() method happens to install
1528 another file in sys.stdout.
1529
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001530- Issue #3088: Corrected a race condition in classes derived from
1531 threading.local: the first member set by a thread could be saved in
1532 another thread's dictionary.
1533
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001534- Issue #3004: Minor change to slice.indices(): the start and stop
1535 arguments are now treated identically, making the behaviour easier
1536 to describe and understand. For example, slice(None, -10,
1537 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1538 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1539 10, -1).
1540
Georg Brandl278fc502008-07-19 12:46:12 +00001541- Issue #3219: Calling a function with repeated keyword arguments,
1542 f(a=2, a=23), would not cause a syntax error. This was a regression
1543 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001544
Georg Brandl278fc502008-07-19 12:46:12 +00001545- Issue #2862: Make int and float freelist management consistent with
1546 other freelists. Changes their CompactFreeList apis into
1547 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001548

1550-------
1551
Thomas Heller57adf222008-08-14 19:10:48 +00001552- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1553 api functions without holding the GIL, which could lead to a fatal
1554 error when they failed.
1555
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001556- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001564- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1565 ForkingPickler.register() to resolve conflict with ctypes.
1566
Vinay Sajip51e65192008-07-18 09:01:10 +00001567- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001568
Thomas Heller880f5292008-07-15 19:39:38 +00001569- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1570 a valid dlerror() message.
1571
Thomas Heller2bad6572008-07-15 17:19:50 +00001572- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1573 incomplete structure was created.
1574
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001575- Issue #3339: dummy_thread.acquire() should not return None.
1576
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001577- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1578
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001579- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001580
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001581- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1582 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001583 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001584 content-length. The problem had been corrected in the 2.4 branch, but never
1585 merged into trunk.
1586
Georg Brandle78fbcc2008-07-05 10:13:36 +00001587- Issue #2663: add filtering capability to shutil.copytree().

1590
1591- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1592

Georg Brandl5cc774e2008-06-11 20:28:06 +00001993 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001994
1995 This is controlled by the configure argument ``--with-universal-archs``:
1996
1997 - ``--with-universal-archs=all``: install 4-way universal
1998
1999 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2000
2001 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2002
2003 This option should be used in combination with ``--enable-universalsdk=``.
2004
2005 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 +00002055- Issue #1631171: Re-implement the 'warnings' module in C (the
2056 original Python code has been kept as backup). This will allow for
2057 using the 'warning's machinery in such places as the parser where
2058 use of pure Python code is not possible. Both the ``showarning()``
2059 and ``formatwarning()`` gain an optional 'line' argument which is
2060 not called by default for backwards-compatibility reasons. Setting
2061 ``warnings.showwarning()`` to an implementation that lacks support
2062 for the ``line`` argument will raise a DeprecationWarning.

2086
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002087- The getpass module has been improved on Unix. It now uses /dev/tty
2088 by default and uses stderr instead of stdout. A GetPassWarning is
2089 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002105 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002125- Issue #2550: The approach used by client/server code for obtaining
2126 ports to listen on in network-oriented tests has been refined in an
2127 effort to facilitate running multiple instances of the entire
2128 regression test suite in parallel without issue.
2129 test_support.bind_port() has been fixed such that it will always
2130 return a unique port -- which wasn't always the case with the
2131 previous implementation, especially if socket options had been set
2132 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2133 new implementation of bind_port() will actually raise an exception
2134 if it is passed an AF_INET/SOCK_STREAM socket with either the
2135 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2136 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2137 the socket it's been passed. This currently only applies to
2138 Windows. This option prevents any other sockets from binding to the
2139 host/port we've bound to, thus removing the possibility of the
2140 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2141 when a second SOCK_STREAM socket binds and accepts to a host/port
2142 that's already been bound by another socket. The optional preferred
2143 port parameter to bind_port() has been removed. Under no
2144 circumstances should tests be hard coding ports!
2145
2146 test_support.find_unused_port() has also been introduced, which will
2147 pass a temporary socket object to bind_port() in order to obtain an
2148 unused port. The temporary socket object is then closed and
2149 deleted, and the port is returned. This method should only be used
2150 for obtaining an unused port in order to pass to an external program
2151 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2152 a parameter to a server-oriented class that doesn't give you direct
2153 access to the underlying socket used.
2154
2155 Finally, test_support.HOST has been introduced, which should be used

2431Core and builtins
2432-----------------
2433
Fred Drakea8ee94b2008-03-01 02:45:07 +00002434- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002435 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002436
Georg Brandlad61bc82008-02-23 15:11:18 +00002437- Issue #2067: file.__exit__() now calls subclasses' close() method.
2438
2439- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002440
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002441- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002442 issue 215555 for a discussion.
2443
Eric Smitha73fbe72008-02-23 03:09:44 +00002444- Added the future_builtins module, which contains hex() and oct().
2445 These are the PEP 3127 version of these functions, designed to be
2446 compatible with the hex() and oct() builtins from Python 3.0. They
2447 differ slightly in their output formats from the existing, unchanged
2448 Python 2.6 builtins. The expected usage of the future_builtins
2449 module is:
2450 from future_builtins import hex, oct
2451
Eric Smith7ef40bf2008-02-20 23:34:22 +00002452- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2453 exponents for exponents with absolute value < 100. Follows C99
2454 standard. This is a change on Windows, which would use 3 digits.
2455 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2456 so that any alterations it does to the resulting string will be
2457 available in stringlib/formatter.h (for float.__format__).
2458
Eric Smith5a3c1352008-02-19 13:21:56 +00002459- Implemented PEP 3101, Advanced String Formatting. This adds a new
2460 builtin format(); a format() method for str and unicode; a
2461 __format__() method to object, str, unicode, int, long, float, and
2462 datetime; the class string.Formatter; and the C API
2463 PyObject_Format().
2464
Georg Brandl3ee81df2008-05-17 18:14:43 +00002465- Fixed several potential crashes, all caused by specially crafted
2466 __del__ methods exploiting objects in temporarily inconsistent
2467 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002468
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002469- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470 prevent a possible crash: an Abstract Base Class would try to access
2471 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002472
Georg Brandl3ee81df2008-05-17 18:14:43 +00002473- Fixed repr() and str() of complex numbers with infinity or nan as
2474 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Clear all free lists during a gc.collect() of the highest generation
2477 in order to allow pymalloc to free more arenas. Python may give back
2478 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002479
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480- Issue #2045: Fix an infinite recursion triggered when printing a
2481 subclass of collections.defaultdict, if its default_factory is set
2482 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002483
Christian Heimesf75dbef2008-02-08 00:11:31 +00002484- Fixed a minor memory leak in dictobject.c. The content of the free
2485 list was not freed on interpreter shutdown.
2486
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487- Limit free list of method and builtin function objects to 256
2488 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002489
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2491 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002492 to compact the internal free lists of pre-allocted ints and floats.
2493
Georg Brandl3ee81df2008-05-17 18:14:43 +00002494- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2495 calls. Python expected the return type int but the fork familie
2496 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002497
Georg Brandl3ee81df2008-05-17 18:14:43 +00002498- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2499 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002500
Georg Brandl3ee81df2008-05-17 18:14:43 +00002501- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2502 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002503
Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2505 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002506
Georg Brandl3ee81df2008-05-17 18:14:43 +00002507- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2508 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002509
Georg Brandl3ee81df2008-05-17 18:14:43 +00002510- Patch #1473257: generator objects gain a gi_code attribute. This is
2511 the same object as the func_code attribute of the function that
2512 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002513
Georg Brandl3ee81df2008-05-17 18:14:43 +00002514- Issue #1920: "while 0" statements were completely removed by the
2515 compiler, even in the presence of an "else" clause, which is
2516 supposed to be run when the condition is false. Now the compiler
2517 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002518
Guido van Rossumeead05f2008-01-24 18:21:02 +00002519- A few crashers fixed: weakref_in_del.py (issue #1377858);
2520 loosing_dict_ref.py (issue #1303614, test67.py);
2521 borrowed_ref_[34].py (not in tracker).
2522
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002523- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002524 suppressed while an extension is loaded by calling SetErrorMode in
2525 dynload_win.c. The error is still reported properly.
2526
Georg Brandl3ee81df2008-05-17 18:14:43 +00002527- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002528 several extension methods and modules do not work without unicode
2529 support.
2530
Georg Brandl26543b12008-01-21 18:36:51 +00002531- Issue #1882: when compiling code from a string, encoding cookies in the
2532 second line of code were not always recognized correctly.
2533
Georg Brandl14404b62008-01-19 19:27:05 +00002534- Issue #1679: "0x" was taken as a valid integer literal.
2535
Georg Brandl6caad7d2008-01-26 14:19:22 +00002536- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002537 added.
2538
Christian Heimesc94e2b52008-01-14 04:13:37 +00002539- sys.float_info / PyFloat_GetInfo: The floating point information
2540 object was converted from a dict to a specialized structseq object.
2541
Georg Brandl3ee81df2008-05-17 18:14:43 +00002542- Patch #1816: Added sys.flags structseq. It exposes the status of
2543 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002544
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- Objects/structseq.c: Implemented new structseq representation. The
2546 patch makes structseqs (e.g. the return value of os.stat) more
2547 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002548
Georg Brandl3ee81df2008-05-17 18:14:43 +00002549- Patch #1700288: added a type attribute cache that caches method
2550 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002551
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002552- Bug #1776: __import__() no longer accepts filenames on any platform.
2553 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002554
Georg Brandlaed6c662008-01-07 17:25:53 +00002555- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2556
Georg Brandl3ee81df2008-05-17 18:14:43 +00002557- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2558 envvar and sys.dont_write_bytecode attribute. All these can be set
2559 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002560
Georg Brandl3ee81df2008-05-17 18:14:43 +00002561- Improve some exception messages when Windows fails to load an
2562 extension module. Now we get for example '%1 is not a valid Win32
2563 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2568 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002569
Christian Heimes0a8143f2007-12-18 23:22:54 +00002570- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002571 and INF. float("nan"), float("inf") and float("-inf") now work on
2572 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002573
Georg Brandl3ee81df2008-05-17 18:14:43 +00002574- Compiler now generates simpler and faster code for dictionary
2575 literals. The oparg for BUILD_MAP now indicates an estimated
2576 dictionary size. There is a new opcode, STORE_MAP, for adding
2577 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002578
Georg Brandl3ee81df2008-05-17 18:14:43 +00002579- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002581- Issue #1620: New property decorator syntax was modifying the
2582 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002583
Georg Brandl3ee81df2008-05-17 18:14:43 +00002584- Issue #1538: Avoid copying string in split/rsplit if the split char
2585 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002587- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002588 SystemError.
2589
Nick Coghlanef01d822007-12-03 12:55:17 +00002590- PEP 366: Allow explicit relative imports when executing modules
2591 inside packages with the -m switch via a new module level
2592 __package__ attribute.
2593
Georg Brandl3ee81df2008-05-17 18:14:43 +00002594- Issue #1402: Fix a crash on exit, when another thread is still
2595 running, and if the deallocation of its frames somehow calls the
2596 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002597

2607 file can now be directly executed by passing their name to the
2608 interpreter. The directory/zipfile is automatically inserted as the
2609 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002610
Georg Brandl3ee81df2008-05-17 18:14:43 +00002611- Issue #1265: Fix a problem with sys.settrace, if the tracing
2612 function uses a generator expression when at the same time the
2613 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002614
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002615- sets and frozensets now have an isdisjoint() method.
2616
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002617- optimize the performance of builtin.sum().
2618
Neal Norwitz44f326e2007-10-05 05:29:17 +00002619- Fix warnings found by the new version of the Coverity checker.
2620
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621- The enumerate() builtin function is no longer bounded to sequences
2622 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2623 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002624
Georg Brandl3ee81df2008-05-17 18:14:43 +00002625- Issue #1686386: Tuple's tp_repr did not take into account the
2626 possibility of having a self-referential tuple, which is possible
2627 from C code. Nor did object's tp_str consider that a type's tp_str
2628 could do something that could lead to an inifinite recursion.
2629 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2630 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002631
Georg Brandl3ee81df2008-05-17 18:14:43 +00002632- Issue #1164: It was possible to trigger deadlock when using the
2633 'print' statement to write to a file since the GIL was not released
2634 as needed. Now PyObject_Print() does the right thing along with
2635 various tp_print implementations of the built-in types and those in
2636 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002638- Issue #1147: Exceptions were directly allowing string exceptions in
2639 their throw() method even though string exceptions no longer
2640 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002641
Georg Brandl3ee81df2008-05-17 18:14:43 +00002642- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002645- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002646 PyObject_Call() never calling back out to Python code to trigger
2647 recursion depth updates/checks. Required the creation of a static
2648 RuntimeError instance in case normalizing an exception put the
2649 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002665- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002666 __*__ attributes. (Some already existed, e.g., __doc__ and
2667 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002668
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002669- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00002676 "except E as target:". This is to provide forwards compatibility
2677 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002678
Brett Cannon229cee22007-05-05 01:34:02 +00002679- Deprecate BaseException.message as per PEP 352.
2680
Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Issue #1303614: don't expose object's __dict__ when the dict is

2683
Vinay Sajip8549ce32007-05-06 17:53:37 +00002684- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002685 setting a plain string, ie don't expand to single letter identifiers.
2686
Raymond Hettinger13936692007-04-11 18:40:58 +00002687- Request #1191699: Slices can now be pickled.
2688
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002689- Request #1193128: str.translate() now allows a None argument for
2690 translations that only remove characters without re-mapping the
2691 remaining characters.
2692
Georg Brandl5cb76c12007-03-21 09:00:39 +00002693- Patch #1682205: a TypeError while unpacking an iterable is no longer

2697
Guido van Rossum143b5642007-03-23 04:58:42 +00002698- Bug #1683368: The object.__init__() and object.__new__() methods are
2699 now stricter in rejecting excess arguments. The only time when
2700 either allows excess arguments is when it is not overridden and the
2701 other one is. For backwards compatibility, when both are
2702 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002703 warning later). Also, type.__init__() insists on the same signature
2704 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2707 object to complex using its __complex__() method before falling back
2708 to the __float__() method. Therefore, the functions in the cmath
2709 module now can operate on objects that define a __complex__()
2710 method.

2713 __slots__. The old and the new class are still required to have the
2714 same slot names.

2727
Georg Brandl7b9c5552007-03-12 14:30:05 +00002728- Bug #1678647: write a newline after printing an exception in any
2729 case, even when converting the value to a string failed.
2730
Georg Brandl871f1bc2007-03-12 13:17:36 +00002731- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002732 its argument, if it exists. If not, it will work like before. This
2733 allows customizing the output of dir() in the presence of a
2734 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002735
Collin Winter276887b2007-03-12 16:11:39 +00002736- Patch #922167: Python no longer segfaults when faced with infinitely
2737 self-recursive reload() calls (as reported by bug #742342).
2738

2743 parthensized forms. This means complex(repr(x)) now works instead of
2744 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002745
Georg Brandlaa2321b2007-03-07 00:40:28 +00002746- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747 makes the filenames the warning module prints much more sensible
2748 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002749

Georg Brandl0fca97a2007-03-05 22:28:08 +00002761- Patch #1674228: when assigning a slice (old-style), check for the
2762 sq_ass_slice instead of the sq_slice slot.
2763
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- When printing an unraisable error, don't print exceptions. before
2765 the name. This duplicates the behavior whening normally printing
2766 exceptions.

2775 created a weakref on itself during a __del__ call for new-style
2776 classes (classic classes still have the bug).

3389
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- unittest now verifies more of its assumptions. In particular,

3392 accepted in TestSuite.addTest(). This should cause no
3393 incompatibility since it never made sense with ordinary subclasses
3394 -- the failure just occurred later, with a more cumbersome
3395 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3677 with RFC 3207 and forgets any knowledge obtained from the server not
3678 obtained from the TLS negotiation itself. Patch contributed by Bill
3679 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003682 that the SMTP.starttls() caller no longer needs to call ehlo()
3683 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003684 does not claim to support starttls. Adds the
3685 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003740- itertools.chain() now has an alternate constructor,

3766 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3767 silently miscode subclasses of those types. Now, it raises a
3768 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003769

Georg Brandl3ee81df2008-05-17 18:14:43 +00003784 time so that opening a database previously created with the DB_DUP
3785 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3786 opens. Specifically: dictionary assignment to a DB object will
3787 replace all values for a given key when the database allows
3788 duplicate values. DB users should use DB.put(k, v) when they want
3789 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003790

3796 characters with ASCII value less than 32. Also, it correctly quotes
3797 dots only if they occur on a single line, as opposed to the previous
3798 behavior of quoting dots if they are the second character of any
3799 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003800

4123
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124- Unified naming convention for free lists and their limits. All free
4125 lists in Object/ are named ``free_list``, the counter ``numfree``
4126 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4127 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004128
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4130 to ``PyTuple_SetItem``, it can be used to populate a brand new
4131 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004132
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004133- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004134
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4136 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4137 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004138
4139- Patch #1720595: add T_BOOL to the range of structmember types.
4140
4141- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4142 ``PyFloat_GetInfo()`` to the float API.
4143
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4145 of w# format code incorrectly truncated the length to an int, even
4146 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4147 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004148
Georg Brandl3ee81df2008-05-17 18:14:43 +00004149- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4150 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- PEP 3123: Provide forward compatibility with Python 3.0, while
4153 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4154 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004155
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4157 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004158
4159- Patch #1733960: Allow T_LONGLONG to accept ints.
4160
4161- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4162
Christian Heimes000a0742008-01-03 22:16:32 +00004163- Added a new API function ``PyImport_ImportModuleNoBlock``.
4164
Georg Brandl6caad7d2008-01-26 14:19:22 +00004165- Bug #1637022: Prefix AST symbols with _Py_.
4166
4167- Fix some leftovers from the conversion from int to Py_ssize_t
4168 (relevant to strings and sequences of more than 2**31 items).
4169
4170- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4171 outside of pystate.c and should not be necessary.
4172
Georg Brandl3ee81df2008-05-17 18:14:43 +00004173- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4174 absolute imports. In earlier versions they might have used relative
4175 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004176
Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4178 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4181 macro so it can be used as an expression.

4186
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4188 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4189 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4190 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4193 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00004203- buildtools now raises a DeprecationWarning.
4204
Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- Removed the macfs module. It had been deprecated since Python 2.5.
4206 This lead to the deprecation of macostools.touched() as it relied
4207 solely on macfs and was a no-op under OS X.
