19 were suppressing all exceptions. These include list(), filter(), map(),
20 zip(), and bytearray().
21
Antoine Pitroua1b22ce2009-01-13 23:25:47 +000022- Issue #4935: The overflow checking code in the expandtabs() method common
23 to str, bytes and bytearray could be optimized away by the compiler, letting

29 an existing .py counterpart, override the co_filename attributes of all
30 code objects if the original filename is obsolete (which can happen if the
31 file has been renamed, moved, or if it is accessed through different paths).
32 Patch by Ziga Seilnacht and Jean-Paul Calderone.
33
Georg Brandl734373c2009-01-03 21:55:17 +000034- Issue #4075: Use OutputDebugStringW in Py_FatalError.

60 exceptions.
61
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +000062- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

68
Vinay Sajip6badbe92009-01-20 22:49:13 +000069- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000070 method on file objects with closefd=False. The file descriptor is still
71 kept open but the file object behaves like a closed file. The ``FileIO``

93 inside its source path if it began with the same letters (e.g. "src" vs.
94 "src.new").
95
Raymond Hettingerc9794482009-01-28 23:14:58 +000096- Issue 4920: Fixed .next() vs .__next__() issues in the ABCs for

106 allow adding directories to a zipfile.
107
Antoine Pitrou19fec8b2009-01-21 00:56:37 +0000108- Issue #5008: When a file is opened in append mode with the new IO library,
109 do an explicit seek to the end of file (so that e.g. tell() returns the
110 file size rather than 0). This is consistent with the behaviour of the
111 traditional 2.x file object.
112
Amaury Forgeot d'Arc0293c802009-01-17 16:46:35 +0000113- Issue #3997: zipfiles generated with more than 65536 files could not be

Raymond Hettingerd263bd82008-12-31 04:18:44 +0000123- Issue 4790: The nsmallest() and nlargest() functions in the heapq module
124 did unnecessary work in the common case where no key function was specified.
125
Martin v. Löwis918ae522008-12-29 16:23:43 +0000126- Issue #3767: Convert Tk object to string in tkColorChooser.

142 zipimport (or any other conformant PEP 302 loader). Original patch by
143 Alexander Belopolsky.
144
145- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
146 302 conformant loader) will now work correctly in most cases (they
147 are still subject to the constraints that exist for all code running
148 from inside a module loaded via a PEP 302 loader and attempting to
149 perform IO operations based on __file__). Original patch by
150 Alexander Belopolsky.

208
Amaury Forgeot d'Arc00c94ed2008-10-07 20:40:09 +0000209- Issue #4069: When set.remove(element) is used with a set element, the element

471
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000472- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
473 PyString_FromFormat or PyErr_Format to display size_t values. The macro
474 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
475 ``printf`` function, whereas PyString_FromFormat has an independent
476 implementation and uses "%zd" on all platforms for size_t values.
477 This makes a difference on win64, where ``printf`` needs "%Id" to display
478 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000495 was correctly parsed but parsing of subsequent arguments failed.
496
Vinay Sajip35e3b032008-09-01 14:33:59 +0000497- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000498 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
499 mechanism. In the process, fix a bug where isinstance() and issubclass(),
500 when given a tuple of classes as second argument, were looking up
501 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
502 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000638What's New in Python 2.6 beta 3?
639================================
640
Barry Warsaw07a4a382008-08-21 01:15:08 +0000641*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000642
643Core and Builtins
644-----------------
645
Guido van Rossumf8402962008-08-20 15:01:50 +0000646- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
647 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
648 extensions do not automatically benefit from the class attribute
649 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
650 to their tp_flags field if they care. This is a backwards
651 compatibility feature; in 3.0, all types will use the cache by
652 default.
653
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000654- Keyword arguments can now follow starred arguments. (``f(a, *args,
655 keyword=23)`` is now valid syntax.)
656
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000657- ctypes function pointers that are COM methods have a boolean True
658 value again.
659
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000660- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
661 by denying s# to parse objects that have a releasebuffer procedure,
662 and introducing s*.
663
Georg Brandl1e13ea92008-08-11 09:07:59 +0000664- Issue #3537: Fix an assertion failure when an empty but presized dict
665 object was stored in the freelist.
666
Mark Dickinsonb6467572008-08-04 21:30:09 +0000667- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
668 ValueError consistently across platforms.
669
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000670- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
671 (64bit Unix, for example), unichr() would truncate its argument and return
672 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
673
Neal Norwitze7d8be82008-07-31 17:17:14 +0000674- Apply security patches from Apple.
675
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000676- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
677 PyErr_ExceptionMatches returns 0 when an exception occurs there.
678
Antoine Pitrou92f82162008-07-25 22:22:08 +0000679- Issue #1819: function calls with several named parameters are now on
680 average 35% faster (as measured by pybench).
681
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000682- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
683 the python debugger steps into a class statement: the free variables (local
684 variables defined in an outer scope) would be deleted from the outer scope.
685
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000686- Issue #2620: Overflow checking when allocating or reallocating memory
687 was not always being done properly in some python types and extension
688 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
689 all been updated to perform better checks and places in the code that
690 would previously leak memory on the error path when such an allocation
691 failed have been fixed.
692
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000693Library
694-------
695
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000696- Issue #3612: Added some missing basic types in ctypes.wintypes.
697
Benjamin Petersone977ad42008-08-20 01:42:01 +0000698- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
699 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
700
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000701- Issue #2234: distutils failed for some versions of the cygwin compiler. The
702 version reported by these tools does not necessarily follow the python
703 version numbering scheme, so the module is less strict when parsing it.
704
Nick Coghlanf70385a2008-08-18 12:42:46 +0000705- Issue #2235: Added Py3k warnings for types which will become unhashable
706 under the stricter __hash__ inheritance rules in 3.0. Several types
707 which did not meet the rules for hash invariants and were already
708 unhashable in 3.0 have now been explicitly flagged as unhashable in
709 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
710 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
711
Brett Cannon88f801d2008-08-18 00:46:22 +0000712- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
713 imported into the module but exposed as part of the module's API.
714
Brett Cannon7b96f072008-08-18 00:41:11 +0000715- Remove an unneeded import of abc.ABCMeta from 'inspect'.
716
Brett Cannon46225e72008-08-18 00:36:52 +0000717- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
718
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000719- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
720
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000721- Issue #3575: Incremental decoder's decode function now takes bytearray
722 by using 's*' instead of 't#'.
723
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000724- Issue #2222: Fixed reference leak when occured os.rename()
725 fails unicode conversion on 2nd parameter. (windows only)
726
Facundo Batista94f243a2008-08-17 03:38:39 +0000727- Issue 2464. urllib2 now supports a malformation in the URL received
728 in a redirect.
729
Brett Cannonabe423e2008-08-16 21:47:07 +0000730- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000731 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000732
Facundo Batistaeb90b782008-08-16 14:44:07 +0000733- Issue #2776: fixed small issue when handling an URL with double slash
734 after a 302 response in the case of not going through a proxy.
735
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000736- Issue #2676: in the email package, content-type parsing was hanging on
737 pathological input because of quadratic or exponential behaviour of a
738 regular expression.
739
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000740- Issue #3476: binary buffered reading through the new "io" library is now
741 thread-safe.
742
Brett Cannonbf3157b2008-08-14 05:00:03 +0000743- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
744 since mimetools itself is deprecated. Because modules are cached, all
745 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
746
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000747- Issue #3134: shutil referenced undefined WindowsError symbol.
748
Robert Schuppenies14646332008-08-10 11:01:53 +0000749- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
750 menu entries were not deleted.
751
Brett Cannon83e81842008-08-09 23:30:55 +0000752- Copied the implementation of reduce() to _functools.reduce() to have a
753 version that did not raise a DeprecationWarning under -3.
754
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000755- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
756 a MemoryError rather than silently stop the iteration.
757
Guido van Rossum59ce9012008-08-09 14:55:34 +0000758- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
759 to _sre.compile() will now be rejected. This should not affect anybody
760 since the re.compile() function never generates invalid re-bytecode.
761
Skip Montanaroa032bf42008-08-08 22:52:51 +0000762- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
763 upon first access it can be automatically initialized from the csv file if
764 it wasn't initialized during instantiation.
765
Brett Cannon3aa2a492008-08-06 22:28:09 +0000766- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
767 the reload() built-in has been removed.
768
Brett Cannon7e30b672008-08-04 21:52:25 +0000769- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000770 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +0000771 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
772 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
773 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
774 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
775 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000776
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000777- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
778 raised an AttributeError.
779
Benjamin Peterson01a24322008-07-28 23:35:27 +0000780- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000781 asking for a specific length. This problem only affected files opened
782 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000783
Mark Dickinsonfe84cce2008-07-27 06:39:07 +0000784- Issue #3449: Update decimal module to use most recent specification
785 (v. 1.68) and tests (v. 2.58) from IBM.

788
Raymond Hettinger8c664e82008-07-25 18:43:33 +0000789- Issue 1592: Improve error reporting when operations are attempted
790 on a closed shelf.
791
Georg Brandlf9efabb2008-07-23 15:16:45 +0000792- Deprecate the "ast" parser function aliases.
793
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000794- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
795
796- Issue #3303: Fix a crash in locale.strcoll() when calling it with
797 invalid arguments.
798

800 with None arguments.
801
802- Issue #3389: Allow resolving dotted names for handlers in logging
803 configuration files.
804
805- Deprecate the sunaudio module for removal in Python 3.0.
806
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000807- Issue #3394: zipfile.writestr sets external attributes when passed a
808 file name rather than a ZipInfo instance, so files are extracted with
809 mode 0600 rather than 000 under Unix.
810
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000811- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
812 argument in python 2.5, this broke code that subclassed Popen to include its
813 own poll method. Fixed my moving _deadstate to an _internal_poll method.
814
Martin v. Löwis8dbf3642008-08-01 14:10:26 +0000815Build
816-----
817
818- Generate the PatternGrammar pickle during "make install".
819
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000820Documentation
821-------------
822
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000823- Issue #2235: the C API function PyObject_HashNotImplemented and its
824 interaction with the tp_hash slot (added in 2.6b2) are now documented
825
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000826- Issue #643841: The language reference now provides more detailed
827 coverage of the lookup process for special methods. The disclaimers
828 regarding lack of coverage of new-style classes have also been
829 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000832What's New in Python 2.6 beta 2?
833================================
834
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000835*Release date: 17-Jul-2008*
836
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000837Core and Builtins
838-----------------
839
Georg Brandl3e483f62008-07-16 22:57:41 +0000840- Issue #3156: Fix inconsistent behavior of the bytearray type: all
841 its methods now allow for items objects that can be converted to
842 an integer using operator.index().
843
Mark Dickinson64b7e502008-07-16 09:40:03 +0000844- Issue #3360: Fix incorrect parsing of '020000000000.0', which
845 produced a ValueError instead of giving the correct float.
846
Eric Smitha5fa5a22008-07-16 00:11:49 +0000847- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
848 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
849
Mark Dickinson7103aa42008-07-15 19:08:33 +0000850- Issue #3008: the float type has a new instance method 'float.hex'
851 and a new class method 'float.fromhex' to convert floating-point
852 numbers to and from hexadecimal strings, respectively.
853
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000854- Issue #2235: __hash__ is once again inherited by default. To allow
855 collections.Hashable to remain meaningful in the presence of the
856 default hash implementation (object.__hash__), it is now possible
857 to explicit block inheritance of hash by setting __hash__=None at
858 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
859 level.
860
Nick Coghlanb028f502008-07-13 14:52:36 +0000861- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
862 the parent module cannot be found while performing an absolute import.
863 This means that an incorrectly defined __package__ attribute will
864 now only prevent relative imports in that module rather than causing
865 all imports from that module to fail.
866
Nick Coghlan14ff9942008-07-08 14:21:42 +0000867- Issue #2517: Allow unicode messages in Exceptions again by correctly
868 bypassing the instance dictionary when looking up __unicode__ on
869 new-style classes.
870
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000871- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
872 set to a custom object whose write() method happens to install
873 another file in sys.stdout.
874
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000875- Issue #3088: Corrected a race condition in classes derived from
876 threading.local: the first member set by a thread could be saved in
877 another thread's dictionary.
878
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000879- Issue #3004: Minor change to slice.indices(): the start and stop
880 arguments are now treated identically, making the behaviour easier
881 to describe and understand. For example, slice(None, -10,
882 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
883 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
884 10, -1).
885
Georg Brandl278fc502008-07-19 12:46:12 +0000886- Issue #3219: Calling a function with repeated keyword arguments,
887 f(a=2, a=23), would not cause a syntax error. This was a regression
888 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000889
Georg Brandl278fc502008-07-19 12:46:12 +0000890- Issue #2862: Make int and float freelist management consistent with
891 other freelists. Changes their CompactFreeList apis into
892 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +0000893
Brett Cannon8bb8fa52008-07-02 01:57:08 +0000894Library
895-------
896
Thomas Heller57adf222008-08-14 19:10:48 +0000897- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
898 api functions without holding the GIL, which could lead to a fatal
899 error when they failed.
900
Martin v. Löwisaabf4042008-08-02 07:20:25 +0000901- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
902
Jesse Noller7fb96402008-07-17 21:01:05 +0000903- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

908
Jesse Noller13e9d582008-07-16 14:32:36 +0000909- Issue #3125: Remove copy_reg in multiprocessing and replace it with
910 ForkingPickler.register() to resolve conflict with ctypes.
911
Vinay Sajip51e65192008-07-18 09:01:10 +0000912- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +0000913
Thomas Heller880f5292008-07-15 19:39:38 +0000914- Issue #3313: Fixed a crash when a failed dlopen() call does not set
915 a valid dlerror() message.
916
Thomas Heller2bad6572008-07-15 17:19:50 +0000917- Issue #3258: Fixed a crash when a ctypes POINTER type to an
918 incomplete structure was created.
919
Brett Cannon3d0b9f02008-07-13 01:15:07 +0000920- Issue #3339: dummy_thread.acquire() should not return None.
921
Raymond Hettingerb01713e2008-07-10 14:34:57 +0000922- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
923
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000924- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +0000925
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000926- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
927 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000928 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000929 content-length. The problem had been corrected in the 2.4 branch, but never
930 merged into trunk.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001338 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001339
1340 This is controlled by the configure argument ``--with-universal-archs``:
1341
1342 - ``--with-universal-archs=all``: install 4-way universal
1343
1344 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1345
1346 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1347
1348 This option should be used in combination with ``--enable-universalsdk=``.
1349
1350 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 +00001400- Issue #1631171: Re-implement the 'warnings' module in C (the
1401 original Python code has been kept as backup). This will allow for
1402 using the 'warning's machinery in such places as the parser where
1403 use of pure Python code is not possible. Both the ``showarning()``
1404 and ``formatwarning()`` gain an optional 'line' argument which is
1405 not called by default for backwards-compatibility reasons. Setting
1406 ``warnings.showwarning()`` to an implementation that lacks support
1407 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001470- Issue #2550: The approach used by client/server code for obtaining
1471 ports to listen on in network-oriented tests has been refined in an
1472 effort to facilitate running multiple instances of the entire
1473 regression test suite in parallel without issue.
1474 test_support.bind_port() has been fixed such that it will always
1475 return a unique port -- which wasn't always the case with the
1476 previous implementation, especially if socket options had been set
1477 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1478 new implementation of bind_port() will actually raise an exception
1479 if it is passed an AF_INET/SOCK_STREAM socket with either the
1480 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1481 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1482 the socket it's been passed. This currently only applies to
1483 Windows. This option prevents any other sockets from binding to the
1484 host/port we've bound to, thus removing the possibility of the
1485 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1486 when a second SOCK_STREAM socket binds and accepts to a host/port
1487 that's already been bound by another socket. The optional preferred
1488 port parameter to bind_port() has been removed. Under no
1489 circumstances should tests be hard coding ports!
1490
1491 test_support.find_unused_port() has also been introduced, which will
1492 pass a temporary socket object to bind_port() in order to obtain an
1493 unused port. The temporary socket object is then closed and
1494 deleted, and the port is returned. This method should only be used
1495 for obtaining an unused port in order to pass to an external program
1496 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1497 a parameter to a server-oriented class that doesn't give you direct
1498 access to the underlying socket used.
1499
1500 Finally, test_support.HOST has been introduced, which should be used
1501 for the host argument of any relevant socket calls (i.e. bind and
1502 connect).

1507 test_asynchat and test_socket_ssl.
1508

1776Core and builtins
1777-----------------
1778
Fred Drakea8ee94b2008-03-01 02:45:07 +00001779- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001780 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001781
Georg Brandlad61bc82008-02-23 15:11:18 +00001782- Issue #2067: file.__exit__() now calls subclasses' close() method.
1783
1784- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001785
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001786- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001787 issue 215555 for a discussion.
1788
Eric Smitha73fbe72008-02-23 03:09:44 +00001789- Added the future_builtins module, which contains hex() and oct().
1790 These are the PEP 3127 version of these functions, designed to be
1791 compatible with the hex() and oct() builtins from Python 3.0. They
1792 differ slightly in their output formats from the existing, unchanged
1793 Python 2.6 builtins. The expected usage of the future_builtins
1794 module is:
1795 from future_builtins import hex, oct
1796
Eric Smith7ef40bf2008-02-20 23:34:22 +00001797- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1798 exponents for exponents with absolute value < 100. Follows C99
1799 standard. This is a change on Windows, which would use 3 digits.
1800 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1801 so that any alterations it does to the resulting string will be
1802 available in stringlib/formatter.h (for float.__format__).
1803
Eric Smith5a3c1352008-02-19 13:21:56 +00001804- Implemented PEP 3101, Advanced String Formatting. This adds a new
1805 builtin format(); a format() method for str and unicode; a
1806 __format__() method to object, str, unicode, int, long, float, and
1807 datetime; the class string.Formatter; and the C API
1808 PyObject_Format().
1809
Georg Brandl3ee81df2008-05-17 18:14:43 +00001810- Fixed several potential crashes, all caused by specially crafted
1811 __del__ methods exploiting objects in temporarily inconsistent
1812 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001813
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001814- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001815 prevent a possible crash: an Abstract Base Class would try to access
1816 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001817
Georg Brandl3ee81df2008-05-17 18:14:43 +00001818- Fixed repr() and str() of complex numbers with infinity or nan as
1819 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001820
Georg Brandl3ee81df2008-05-17 18:14:43 +00001821- Clear all free lists during a gc.collect() of the highest generation
1822 in order to allow pymalloc to free more arenas. Python may give back
1823 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001824
Georg Brandl3ee81df2008-05-17 18:14:43 +00001825- Issue #2045: Fix an infinite recursion triggered when printing a
1826 subclass of collections.defaultdict, if its default_factory is set
1827 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001828
Christian Heimesf75dbef2008-02-08 00:11:31 +00001829- Fixed a minor memory leak in dictobject.c. The content of the free
1830 list was not freed on interpreter shutdown.
1831
Georg Brandl3ee81df2008-05-17 18:14:43 +00001832- Limit free list of method and builtin function objects to 256
1833 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001834
Georg Brandl3ee81df2008-05-17 18:14:43 +00001835- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1836 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001837 to compact the internal free lists of pre-allocted ints and floats.
1838
Georg Brandl3ee81df2008-05-17 18:14:43 +00001839- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1840 calls. Python expected the return type int but the fork familie
1841 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001842
Georg Brandl3ee81df2008-05-17 18:14:43 +00001843- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1844 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001845
Georg Brandl3ee81df2008-05-17 18:14:43 +00001846- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1847 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001848
Georg Brandl3ee81df2008-05-17 18:14:43 +00001849- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1850 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001851
Georg Brandl3ee81df2008-05-17 18:14:43 +00001852- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1853 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001854
Georg Brandl3ee81df2008-05-17 18:14:43 +00001855- Patch #1473257: generator objects gain a gi_code attribute. This is
1856 the same object as the func_code attribute of the function that
1857 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001858
Georg Brandl3ee81df2008-05-17 18:14:43 +00001859- Issue #1920: "while 0" statements were completely removed by the
1860 compiler, even in the presence of an "else" clause, which is
1861 supposed to be run when the condition is false. Now the compiler
1862 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001863
Guido van Rossumeead05f2008-01-24 18:21:02 +00001864- A few crashers fixed: weakref_in_del.py (issue #1377858);
1865 loosing_dict_ref.py (issue #1303614, test67.py);
1866 borrowed_ref_[34].py (not in tracker).
1867
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001868- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001869 suppressed while an extension is loaded by calling SetErrorMode in
1870 dynload_win.c. The error is still reported properly.
1871
Georg Brandl3ee81df2008-05-17 18:14:43 +00001872- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001873 several extension methods and modules do not work without unicode
1874 support.
1875
Georg Brandl26543b12008-01-21 18:36:51 +00001876- Issue #1882: when compiling code from a string, encoding cookies in the
1877 second line of code were not always recognized correctly.
1878
Georg Brandl14404b62008-01-19 19:27:05 +00001879- Issue #1679: "0x" was taken as a valid integer literal.
1880
Georg Brandl6caad7d2008-01-26 14:19:22 +00001881- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001882 added.
1883
Christian Heimesc94e2b52008-01-14 04:13:37 +00001884- sys.float_info / PyFloat_GetInfo: The floating point information
1885 object was converted from a dict to a specialized structseq object.
1886
Georg Brandl3ee81df2008-05-17 18:14:43 +00001887- Patch #1816: Added sys.flags structseq. It exposes the status of
1888 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001889
Georg Brandl3ee81df2008-05-17 18:14:43 +00001890- Objects/structseq.c: Implemented new structseq representation. The
1891 patch makes structseqs (e.g. the return value of os.stat) more
1892 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001893
Georg Brandl3ee81df2008-05-17 18:14:43 +00001894- Patch #1700288: added a type attribute cache that caches method
1895 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001896
Neal Norwitz3fc15b82008-01-10 05:42:58 +00001897- Bug #1776: __import__() no longer accepts filenames on any platform.
1898 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00001899
Georg Brandlaed6c662008-01-07 17:25:53 +00001900- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
1901
Georg Brandl3ee81df2008-05-17 18:14:43 +00001902- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
1903 envvar and sys.dont_write_bytecode attribute. All these can be set
1904 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001905
Georg Brandl3ee81df2008-05-17 18:14:43 +00001906- Improve some exception messages when Windows fails to load an
1907 extension module. Now we get for example '%1 is not a valid Win32
1908 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00001909
Georg Brandl3ee81df2008-05-17 18:14:43 +00001910- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001912- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
1913 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00001914
Christian Heimes0a8143f2007-12-18 23:22:54 +00001915- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001916 and INF. float("nan"), float("inf") and float("-inf") now work on
1917 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001918
Georg Brandl3ee81df2008-05-17 18:14:43 +00001919- Compiler now generates simpler and faster code for dictionary
1920 literals. The oparg for BUILD_MAP now indicates an estimated
1921 dictionary size. There is a new opcode, STORE_MAP, for adding
1922 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00001923
Georg Brandl3ee81df2008-05-17 18:14:43 +00001924- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001926- Issue #1620: New property decorator syntax was modifying the
1927 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00001928
Georg Brandl3ee81df2008-05-17 18:14:43 +00001929- Issue #1538: Avoid copying string in split/rsplit if the split char
1930 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00001931
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00001932- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00001933 SystemError.
1934
Nick Coghlanef01d822007-12-03 12:55:17 +00001935- PEP 366: Allow explicit relative imports when executing modules
1936 inside packages with the -m switch via a new module level
1937 __package__ attribute.
1938
Georg Brandl3ee81df2008-05-17 18:14:43 +00001939- Issue #1402: Fix a crash on exit, when another thread is still
1940 running, and if the deallocation of its frames somehow calls the
1941 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00001942

1952 file can now be directly executed by passing their name to the
1953 interpreter. The directory/zipfile is automatically inserted as the
1954 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00001955
Georg Brandl3ee81df2008-05-17 18:14:43 +00001956- Issue #1265: Fix a problem with sys.settrace, if the tracing
1957 function uses a generator expression when at the same time the
1958 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00001959
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00001960- sets and frozensets now have an isdisjoint() method.
1961
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00001962- optimize the performance of builtin.sum().
1963
Neal Norwitz44f326e2007-10-05 05:29:17 +00001964- Fix warnings found by the new version of the Coverity checker.
1965
Georg Brandl3ee81df2008-05-17 18:14:43 +00001966- The enumerate() builtin function is no longer bounded to sequences
1967 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1968 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001969
Georg Brandl3ee81df2008-05-17 18:14:43 +00001970- Issue #1686386: Tuple's tp_repr did not take into account the
1971 possibility of having a self-referential tuple, which is possible
1972 from C code. Nor did object's tp_str consider that a type's tp_str
1973 could do something that could lead to an inifinite recursion.
1974 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1975 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001976
Georg Brandl3ee81df2008-05-17 18:14:43 +00001977- Issue #1164: It was possible to trigger deadlock when using the
1978 'print' statement to write to a file since the GIL was not released
1979 as needed. Now PyObject_Print() does the right thing along with
1980 various tp_print implementations of the built-in types and those in
1981 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00001982
Georg Brandl3ee81df2008-05-17 18:14:43 +00001983- Issue #1147: Exceptions were directly allowing string exceptions in
1984 their throw() method even though string exceptions no longer
1985 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00001986
Georg Brandl3ee81df2008-05-17 18:14:43 +00001987- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00001990- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001991 PyObject_Call() never calling back out to Python code to trigger
1992 recursion depth updates/checks. Required the creation of a static
1993 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00002011 __*__ attributes. (Some already existed, e.g., __doc__ and
2012 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002013

2022 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002023
Brett Cannon229cee22007-05-05 01:34:02 +00002024- Deprecate BaseException.message as per PEP 352.
2025

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002030 setting a plain string, ie don't expand to single letter identifiers.
2031
Raymond Hettinger13936692007-04-11 18:40:58 +00002032- Request #1191699: Slices can now be pickled.

2042
Guido van Rossum143b5642007-03-23 04:58:42 +00002043- Bug #1683368: The object.__init__() and object.__new__() methods are
2044 now stricter in rejecting excess arguments. The only time when
2045 either allows excess arguments is when it is not overridden and the
2046 other one is. For backwards compatibility, when both are
2047 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002048 warning later). Also, type.__init__() insists on the same signature
2049 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002050
Georg Brandl3ee81df2008-05-17 18:14:43 +00002051- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2052 object to complex using its __complex__() method before falling back
2053 to the __float__() method. Therefore, the functions in the cmath
2054 module now can operate on objects that define a __complex__()
2055 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002073- Bug #1678647: write a newline after printing an exception in any
2074 case, even when converting the value to a string failed.
2075
Georg Brandl871f1bc2007-03-12 13:17:36 +00002076- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002077 its argument, if it exists. If not, it will work like before. This
2078 allows customizing the output of dir() in the presence of a
2079 __getattr__().

2089 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002090
Georg Brandlaa2321b2007-03-07 00:40:28 +00002091- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002092 makes the filenames the warning module prints much more sensible
2093 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002094

Georg Brandl0fca97a2007-03-05 22:28:08 +00002106- Patch #1674228: when assigning a slice (old-style), check for the
2107 sq_ass_slice instead of the sq_slice slot.
2108
Georg Brandl3ee81df2008-05-17 18:14:43 +00002109- When printing an unraisable error, don't print exceptions. before

2734
Georg Brandl3ee81df2008-05-17 18:14:43 +00002735- unittest now verifies more of its assumptions. In particular,

2738 incompatibility since it never made sense with ordinary subclasses
2739 -- the failure just occurred later, with a more cumbersome
2740 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3022 with RFC 3207 and forgets any knowledge obtained from the server not
3023 obtained from the TLS negotiation itself. Patch contributed by Bill
3024 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003025
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003027 that the SMTP.starttls() caller no longer needs to call ehlo()
3028 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029 does not claim to support starttls. Adds the
3030 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3111 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3112 silently miscode subclasses of those types. Now, it raises a
3113 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003114

Georg Brandl3ee81df2008-05-17 18:14:43 +00003129 time so that opening a database previously created with the DB_DUP
3130 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3131 opens. Specifically: dictionary assignment to a DB object will
3132 replace all values for a given key when the database allows
3133 duplicate values. DB users should use DB.put(k, v) when they want
3134 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003135

3141 characters with ASCII value less than 32. Also, it correctly quotes
3142 dots only if they occur on a single line, as opposed to the previous
3143 behavior of quoting dots if they are the second character of any
3144 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003145

Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Unified naming convention for free lists and their limits. All free
3470 lists in Object/ are named ``free_list``, the counter ``numfree``
3471 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3472 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003473
Georg Brandl3ee81df2008-05-17 18:14:43 +00003474- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3475 to ``PyTuple_SetItem``, it can be used to populate a brand new
3476 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003477
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003478- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3481 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3482 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003483
3484- Patch #1720595: add T_BOOL to the range of structmember types.
3485
3486- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3487 ``PyFloat_GetInfo()`` to the float API.
3488
Georg Brandl3ee81df2008-05-17 18:14:43 +00003489- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3490 of w# format code incorrectly truncated the length to an int, even
3491 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3492 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003493
Georg Brandl3ee81df2008-05-17 18:14:43 +00003494- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3495 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003496
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- PEP 3123: Provide forward compatibility with Python 3.0, while
3498 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3499 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003500
Georg Brandl3ee81df2008-05-17 18:14:43 +00003501- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3502 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003503
3504- Patch #1733960: Allow T_LONGLONG to accept ints.
3505
3506- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3507
Christian Heimes000a0742008-01-03 22:16:32 +00003508- Added a new API function ``PyImport_ImportModuleNoBlock``.
3509
Georg Brandl6caad7d2008-01-26 14:19:22 +00003510- Bug #1637022: Prefix AST symbols with _Py_.
3511
3512- Fix some leftovers from the conversion from int to Py_ssize_t
3513 (relevant to strings and sequences of more than 2**31 items).
3514
3515- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3516 outside of pystate.c and should not be necessary.
3517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3519 absolute imports. In earlier versions they might have used relative
3520 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003521
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3523 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3526 macro so it can be used as an expression.

3531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3533 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3534 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3535 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003536
Georg Brandl3ee81df2008-05-17 18:14:43 +00003537- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
3538 _CRT_NONSTDC_NO_DEPRECATE.
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00003539
Martin v. Löwisd476a402007-10-12 08:56:52 +00003540- Bug #1216: Restore support for Visual Studio 2002.

Brett Cannon791d56f2007-05-31 19:40:42 +00003548- buildtools now raises a DeprecationWarning.
3549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Removed the macfs module. It had been deprecated since Python 2.5.
3551 This lead to the deprecation of macostools.touched() as it relied
3552 solely on macfs and was a no-op under OS X.
