114 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
115 argument's __int__ method to convert to an integer before packing. It also
116 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
117 was inconsistent: __int__ was used for some integer codes but not for others,
118 and the set of integer codes for which it was used differed between native
119 packing and standard packing.)

340 strings,
341 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
342 numeric strings corresponding to subnormal values,
343 (3) a memory leak for some values large enough to cause overflow, and
344 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +0000372- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000373 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000374 Also, raise ValueError rather than TypeError when an unknown TIPC address
375 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000379- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000380 file position when calling `truncate()`. It would previously change the file
381 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000382 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
383
Benjamin Petersone06f7112010-01-28 02:15:02 +0000384- UserDict is now a new-style class.
385
Georg Brandlba83f822010-03-14 09:50:54 +0000386- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
387 class used to represent files stored inside an archive. The new
388 implementation is significantly faster and can be wrapped in a
389 ``io.BufferedReader`` object for more speedups. It also solves an issue
390 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
391 Patch by Nir Aides.

399 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000400
Georg Brandlba83f822010-03-14 09:50:54 +0000401- Issue #7748: Since unicode values are supported for some metadata options in
402 Distutils, the DistributionMetadata get_* methods will now return an utf-8
403 encoded string for them. This ensures that the upload and register commands
404 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000406- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000407 headers in multipart/signed MIME parts, which fixes one of the sources of

480
Georg Brandlba83f822010-03-14 09:50:54 +0000481- The ``__complex__()`` method is now looked up on the class of instances to
482 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000484- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
485 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
486
Mark Dickinson1b34d252010-01-01 17:27:30 +0000487- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000488 DeprecationWarning when passed a float argument where an integer was expected.
489 These functions and methods now raise TypeError instead. The majority of the
490 effects of this change are in the extension modules, but some core functions
491 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
492 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000505- Issue #1811: Improve accuracy and cross-platform consistency for true division
506 of integers: the result of a/b is now correctly rounded for ints a and b (at

Georg Brandlba83f822010-03-14 09:50:54 +0000675- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
676 decimal string that's guaranteed to round back to x under correct rounding
677 (with round-half-to-even rounding mode). Previously it gave a string based on
678 rounding x to 17 decimal digits. repr(x) for a complex number behaves
679 similarly. On platforms where the correctly-rounded strtod and dtoa code is
680 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +0000682- Issue #7117: On almost all platforms: float-to-string and string-to-float
683 conversions within Python are now correctly rounded. Places these conversions
684 occur include: str for floats and complex numbers; the float and complex
685 constructors; old-style and new-style numeric formatting; serialization and
686 deserialization of floats and complex numbers using marshal, pickle and json;
687 parsing of float and imaginary literals in Python code; Decimal-to-float
688 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000689
Georg Brandlba83f822010-03-14 09:50:54 +0000690 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
691 providing correctly-rounded strtod and dtoa C functions. This code is
692 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
693 the C compiler. There may be a small number of platforms on which correct
694 operation of this code cannot be guaranteed, so the code is not used: notably,
695 this applies to platforms where the C double format is not IEEE 754 binary64,
696 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
697 and Python's configure script is unable to determine how to change the FPU
698 precision. On these platforms conversions use the platform strtod and dtoa,
699 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000701- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
702 uses the correctly-rounded string <-> float conversions described above (when
703 available), and so produces correctly rounded results that will display nicely
704 under the float repr. There are two related small changes: (1) round now
705 accepts any class with an ``__index__()`` method for its second argument (but
706 no longer accepts floats for the second argument), and (2) an excessively
707 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
708 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000851 (1) inf and nan strings with trailing whitespace were incorrectly rejected;

Georg Brandlba83f822010-03-14 09:50:54 +0000855- Issue #5920: For ``float.__format__()``, change the behavior with the empty
856 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
857 but with at least one decimal point and with a default precision
858 of 12. Previously, the behavior the same but with a default precision of 6.
859 This more closely matches ``str()``, and reduces surprises when adding
860 alignment flags to the empty presentation type. This also affects the new
861 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001001- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1002 existing .py counterpart, override the co_filename attributes of all code
1003 objects if the original filename is obsolete (which can happen if the file has
1004 been renamed, moved, or if it is accessed through different paths). Patch by

1045 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1046 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001049- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1052
Georg Brandlba83f822010-03-14 09:50:54 +00001053- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1058
Georg Brandlba83f822010-03-14 09:50:54 +00001059- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1060 file objects with closefd=False. The file descriptor is still kept open but
1061 the file object behaves like a closed file. The ``FileIO`` object also got a
1062 new readonly attribute ``closefd``.

1081
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001082- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001085- On windows, ``os.chdir()`` given unicode was not working if
1086 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1087 this code path is really executed because I cannot move to such directory on
1088 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001090- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1091 element is temporarily replaced with an equivalent frozenset. But the
1092 eventual KeyError would always report the empty ``frozenset()`` as the missing
1093 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001113- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1114 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1115 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1116 of using the replace error handler in PyUnicode_DecodeUTF8().
1117
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001118- Issue #3739: The unicode-internal encoder now reports the number of characters

1120
Georg Brandlba83f822010-03-14 09:50:54 +00001121- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1122 allocator will be automatically disabled when running under Valgrind. This
1123 gives improved memory leak detection when running under Valgrind, while taking
1124 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002366- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2367 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002368 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2369 the tests if DISPLAY is defined but can't be used.

2375 import both normal and optimised versions of modules. test_heapq and
2376 test_warnings have been adjusted to use it, tests for other modules with both
2377 C and Python implementations in the stdlib can be adjusted to use it over
2378 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002386- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2387 should cause a test to be skipped are now done using import_module from test
2388 support, which does the conversion.

2490
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002491- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2492 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2493 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2494 ``printf`` function, whereas PyString_FromFormat has an independent
2495 implementation and uses "%zd" on all platforms for size_t values.
2496 This makes a difference on win64, where ``printf`` needs "%Id" to display
2497 64bit values.
2498
Benjamin Peterson97179b02008-09-09 20:55:01 +00002499- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2503 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002507- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002513 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002514 was correctly parsed but parsing of subsequent arguments failed.
2515
Vinay Sajip35e3b032008-09-01 14:33:59 +00002516- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002517 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2518 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2519 when given a tuple of classes as second argument, were looking up
2520 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2521 type object.
2522
Neal Norwitz18aa3882008-08-24 05:04:52 +00002523- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002660What's New in Python 2.6 beta 3?
2661================================
2662
Barry Warsaw07a4a382008-08-21 01:15:08 +00002663*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002664
2665Core and Builtins
2666-----------------
2667
Guido van Rossumf8402962008-08-20 15:01:50 +00002668- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2669 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2670 extensions do not automatically benefit from the class attribute
2671 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2672 to their tp_flags field if they care. This is a backwards
2673 compatibility feature; in 3.0, all types will use the cache by
2674 default.
2675
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002676- Keyword arguments can now follow starred arguments. (``f(a, *args,
2677 keyword=23)`` is now valid syntax.)
2678
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002679- ctypes function pointers that are COM methods have a boolean True
2680 value again.
2681
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002682- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2683 by denying s# to parse objects that have a releasebuffer procedure,
2684 and introducing s*.
2685
Georg Brandl1e13ea92008-08-11 09:07:59 +00002686- Issue #3537: Fix an assertion failure when an empty but presized dict
2687 object was stored in the freelist.
2688
Mark Dickinsonb6467572008-08-04 21:30:09 +00002689- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2690 ValueError consistently across platforms.
2691
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002692- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2693 (64bit Unix, for example), unichr() would truncate its argument and return
2694 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2695
Neal Norwitze7d8be82008-07-31 17:17:14 +00002696- Apply security patches from Apple.
2697
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002698- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2699 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2700
Antoine Pitrou92f82162008-07-25 22:22:08 +00002701- Issue #1819: function calls with several named parameters are now on
2702 average 35% faster (as measured by pybench).
2703
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002704- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2705 the python debugger steps into a class statement: the free variables (local
2706 variables defined in an outer scope) would be deleted from the outer scope.
2707
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002708- Issue #2620: Overflow checking when allocating or reallocating memory
2709 was not always being done properly in some python types and extension
2710 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2711 all been updated to perform better checks and places in the code that
2712 would previously leak memory on the error path when such an allocation
2713 failed have been fixed.
2714
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002715Library
2716-------
2717
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002718- Issue #3612: Added some missing basic types in ctypes.wintypes.
2719
Benjamin Petersone977ad42008-08-20 01:42:01 +00002720- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2721 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2722
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002723- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2724 version reported by these tools does not necessarily follow the python
2725 version numbering scheme, so the module is less strict when parsing it.
2726
Nick Coghlanf70385a2008-08-18 12:42:46 +00002727- Issue #2235: Added Py3k warnings for types which will become unhashable
2728 under the stricter __hash__ inheritance rules in 3.0. Several types
2729 which did not meet the rules for hash invariants and were already
2730 unhashable in 3.0 have now been explicitly flagged as unhashable in
2731 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2732 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2733
Brett Cannon88f801d2008-08-18 00:46:22 +00002734- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2735 imported into the module but exposed as part of the module's API.
2736
Brett Cannon7b96f072008-08-18 00:41:11 +00002737- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2738
Brett Cannon46225e72008-08-18 00:36:52 +00002739- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2740
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002741- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2742
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002743- Issue #3575: Incremental decoder's decode function now takes bytearray
2744 by using 's*' instead of 't#'.
2745
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002746- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002747 fails unicode conversion on 2nd parameter. (windows only)
2748
Facundo Batista94f243a2008-08-17 03:38:39 +00002749- Issue 2464. urllib2 now supports a malformation in the URL received
2750 in a redirect.
2751
Brett Cannonabe423e2008-08-16 21:47:07 +00002752- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002753 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002754
Facundo Batistaeb90b782008-08-16 14:44:07 +00002755- Issue #2776: fixed small issue when handling an URL with double slash
2756 after a 302 response in the case of not going through a proxy.
2757
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002758- Issue #2676: in the email package, content-type parsing was hanging on
2759 pathological input because of quadratic or exponential behaviour of a
2760 regular expression.
2761
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002762- Issue #3476: binary buffered reading through the new "io" library is now
2763 thread-safe.
2764
Brett Cannonbf3157b2008-08-14 05:00:03 +00002765- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2766 since mimetools itself is deprecated. Because modules are cached, all
2767 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2768
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002769- Issue #3134: shutil referenced undefined WindowsError symbol.
2770
Robert Schuppenies14646332008-08-10 11:01:53 +00002771- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2772 menu entries were not deleted.
2773
Brett Cannon83e81842008-08-09 23:30:55 +00002774- Copied the implementation of reduce() to _functools.reduce() to have a
2775 version that did not raise a DeprecationWarning under -3.
2776
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002777- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2778 a MemoryError rather than silently stop the iteration.
2779
Guido van Rossum59ce9012008-08-09 14:55:34 +00002780- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2781 to _sre.compile() will now be rejected. This should not affect anybody
2782 since the re.compile() function never generates invalid re-bytecode.
2783
Skip Montanaroa032bf42008-08-08 22:52:51 +00002784- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2785 upon first access it can be automatically initialized from the csv file if
2786 it wasn't initialized during instantiation.
2787
Brett Cannon3aa2a492008-08-06 22:28:09 +00002788- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2789 the reload() built-in has been removed.
2790
Brett Cannon7e30b672008-08-04 21:52:25 +00002791- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002792 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2796 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2797 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002798
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002799- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2800 raised an AttributeError.
2801
Benjamin Peterson01a24322008-07-28 23:35:27 +00002802- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002803 asking for a specific length. This problem only affected files opened
2804 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002805
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002806- Issue #3449: Update decimal module to use most recent specification
2807 (v. 1.68) and tests (v. 2.58) from IBM.
2808
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002809- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2817
2818- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2819 invalid arguments.
2820
2821- Issue #3302: Fix several crashes when calling locale's gettext functions
2822 with None arguments.
2823
2824- Issue #3389: Allow resolving dotted names for handlers in logging
2825 configuration files.
2826
2827- Deprecate the sunaudio module for removal in Python 3.0.
2828
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002829- Issue #3394: zipfile.writestr sets external attributes when passed a
2830 file name rather than a ZipInfo instance, so files are extracted with
2831 mode 0600 rather than 000 under Unix.
2832
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002833- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2834 argument in python 2.5, this broke code that subclassed Popen to include its
2835 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2844
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002845- Issue #2235: the C API function PyObject_HashNotImplemented and its
2846 interaction with the tp_hash slot (added in 2.6b2) are now documented
2847
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002848- Issue #643841: The language reference now provides more detailed
2849 coverage of the lookup process for special methods. The disclaimers
2850 regarding lack of coverage of new-style classes have also been
2851 removed, since the coverage is now fairly reasonable.

2860-----------------
2861
Georg Brandl3e483f62008-07-16 22:57:41 +00002862- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2863 its methods now allow for items objects that can be converted to
2864 an integer using operator.index().
2865
Mark Dickinson64b7e502008-07-16 09:40:03 +00002866- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2867 produced a ValueError instead of giving the correct float.
2868
Eric Smitha5fa5a22008-07-16 00:11:49 +00002869- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2870 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2871
Mark Dickinson7103aa42008-07-15 19:08:33 +00002872- Issue #3008: the float type has a new instance method 'float.hex'
2873 and a new class method 'float.fromhex' to convert floating-point
2874 numbers to and from hexadecimal strings, respectively.
2875
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002876- Issue #2235: __hash__ is once again inherited by default. To allow
2877 collections.Hashable to remain meaningful in the presence of the
2878 default hash implementation (object.__hash__), it is now possible
2879 to explicit block inheritance of hash by setting __hash__=None at
2880 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2881 level.
2882
Nick Coghlanb028f502008-07-13 14:52:36 +00002883- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2884 the parent module cannot be found while performing an absolute import.
2885 This means that an incorrectly defined __package__ attribute will
2886 now only prevent relative imports in that module rather than causing
2887 all imports from that module to fail.
2888
Nick Coghlan14ff9942008-07-08 14:21:42 +00002889- Issue #2517: Allow unicode messages in Exceptions again by correctly
2890 bypassing the instance dictionary when looking up __unicode__ on
2891 new-style classes.
2892
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002893- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2894 set to a custom object whose write() method happens to install
2895 another file in sys.stdout.

2899 another thread's dictionary.
2900
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002901- Issue #3004: Minor change to slice.indices(): the start and stop
2902 arguments are now treated identically, making the behaviour easier
2903 to describe and understand. For example, slice(None, -10,
2904 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2905 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2906 10, -1).
2907
Georg Brandl278fc502008-07-19 12:46:12 +00002908- Issue #3219: Calling a function with repeated keyword arguments,

2910 from 2.4 caused by the switch to the new compiler.

3359 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003360 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003361
3362 This is controlled by the configure argument ``--with-universal-archs``:
3363
3364 - ``--with-universal-archs=all``: install 4-way universal
3365
3366 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3367
3368 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3369
3370 This option should be used in combination with ``--enable-universalsdk=``.

3409 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003410
Christian Heimese74c8f22008-04-19 02:23:57 +00003411- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003422- Issue #1631171: Re-implement the 'warnings' module in C (the
3423 original Python code has been kept as backup). This will allow for
3424 using the 'warning's machinery in such places as the parser where
3425 use of pure Python code is not possible. Both the ``showarning()``
3426 and ``formatwarning()`` gain an optional 'line' argument which is
3427 not called by default for backwards-compatibility reasons. Setting
3428 ``warnings.showwarning()`` to an implementation that lacks support
3429 for the ``line`` argument will raise a DeprecationWarning.

3453
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003454- The getpass module has been improved on Unix. It now uses /dev/tty
3455 by default and uses stderr instead of stdout. A GetPassWarning is
3456 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003471- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003472 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Issue #2385: distutils.core.run_script() makes __file__ available,
3485 so the controlled environment will more closely mirror the typical
3486 script environment. This supports setup.py scripts that refer to
3487 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Issue #2550: The approach used by client/server code for obtaining
3493 ports to listen on in network-oriented tests has been refined in an
3494 effort to facilitate running multiple instances of the entire
3495 regression test suite in parallel without issue.
3496 test_support.bind_port() has been fixed such that it will always
3497 return a unique port -- which wasn't always the case with the
3498 previous implementation, especially if socket options had been set
3499 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3500 new implementation of bind_port() will actually raise an exception
3501 if it is passed an AF_INET/SOCK_STREAM socket with either the
3502 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3503 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3504 the socket it's been passed. This currently only applies to
3505 Windows. This option prevents any other sockets from binding to the
3506 host/port we've bound to, thus removing the possibility of the
3507 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3508 when a second SOCK_STREAM socket binds and accepts to a host/port
3509 that's already been bound by another socket. The optional preferred
3510 port parameter to bind_port() has been removed. Under no
3511 circumstances should tests be hard coding ports!
3512
3513 test_support.find_unused_port() has also been introduced, which will
3514 pass a temporary socket object to bind_port() in order to obtain an
3515 unused port. The temporary socket object is then closed and
3516 deleted, and the port is returned. This method should only be used
3517 for obtaining an unused port in order to pass to an external program
3518 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3519 a parameter to a server-oriented class that doesn't give you direct
3520 access to the underlying socket used.
3521
3522 Finally, test_support.HOST has been introduced, which should be used
3523 for the host argument of any relevant socket calls (i.e. bind and
3524 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003525
3526 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003527 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003528 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3529 test_asynchat and test_socket_ssl.
3530
Georg Brandl3ee81df2008-05-17 18:14:43 +00003531 It is now possible for multiple instances of the regression test
3532 suite to run in parallel without issue.

3800
Fred Drakea8ee94b2008-03-01 02:45:07 +00003801- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003802 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003804- Issue #2067: file.__exit__() now calls subclasses' close() method.
3805
3806- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003807
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003808- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003809 issue 215555 for a discussion.
3810
Eric Smitha73fbe72008-02-23 03:09:44 +00003811- Added the future_builtins module, which contains hex() and oct().
3812 These are the PEP 3127 version of these functions, designed to be
3813 compatible with the hex() and oct() builtins from Python 3.0. They
3814 differ slightly in their output formats from the existing, unchanged
3815 Python 2.6 builtins. The expected usage of the future_builtins
3816 module is:
3817 from future_builtins import hex, oct
3818
Eric Smith7ef40bf2008-02-20 23:34:22 +00003819- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3820 exponents for exponents with absolute value < 100. Follows C99
3821 standard. This is a change on Windows, which would use 3 digits.
3822 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3823 so that any alterations it does to the resulting string will be
3824 available in stringlib/formatter.h (for float.__format__).
3825
Eric Smith5a3c1352008-02-19 13:21:56 +00003826- Implemented PEP 3101, Advanced String Formatting. This adds a new
3827 builtin format(); a format() method for str and unicode; a
3828 __format__() method to object, str, unicode, int, long, float, and
3829 datetime; the class string.Formatter; and the C API
3830 PyObject_Format().
3831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- Fixed several potential crashes, all caused by specially crafted
3833 __del__ methods exploiting objects in temporarily inconsistent
3834 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003835
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003836- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837 prevent a possible crash: an Abstract Base Class would try to access
3838 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- Fixed repr() and str() of complex numbers with infinity or nan as
3841 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003842
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843- Clear all free lists during a gc.collect() of the highest generation
3844 in order to allow pymalloc to free more arenas. Python may give back
3845 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003846
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847- Issue #2045: Fix an infinite recursion triggered when printing a
3848 subclass of collections.defaultdict, if its default_factory is set
3849 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003850
Christian Heimesf75dbef2008-02-08 00:11:31 +00003851- Fixed a minor memory leak in dictobject.c. The content of the free
3852 list was not freed on interpreter shutdown.
3853
Georg Brandl21e99f42010-03-07 15:23:59 +00003854- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003856
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3858 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003859 to compact the internal free lists of pre-allocted ints and floats.
3860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3862 calls. Python expected the return type int but the fork familie
3863 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003864
Georg Brandl3ee81df2008-05-17 18:14:43 +00003865- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3866 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003867
Georg Brandl3ee81df2008-05-17 18:14:43 +00003868- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3869 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003874- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3875 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- Patch #1473257: generator objects gain a gi_code attribute. This is
3878 the same object as the func_code attribute of the function that
3879 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003880
Georg Brandl3ee81df2008-05-17 18:14:43 +00003881- Issue #1920: "while 0" statements were completely removed by the
3882 compiler, even in the presence of an "else" clause, which is
3883 supposed to be run when the condition is false. Now the compiler
3884 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003885
Guido van Rossumeead05f2008-01-24 18:21:02 +00003886- A few crashers fixed: weakref_in_del.py (issue #1377858);
3887 loosing_dict_ref.py (issue #1303614, test67.py);
3888 borrowed_ref_[34].py (not in tracker).
3889
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003890- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003891 suppressed while an extension is loaded by calling SetErrorMode in
3892 dynload_win.c. The error is still reported properly.
3893
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003895 several extension methods and modules do not work without unicode
3896 support.
3897
Georg Brandl26543b12008-01-21 18:36:51 +00003898- Issue #1882: when compiling code from a string, encoding cookies in the
3899 second line of code were not always recognized correctly.
3900
Georg Brandl14404b62008-01-19 19:27:05 +00003901- Issue #1679: "0x" was taken as a valid integer literal.
3902
Georg Brandl6caad7d2008-01-26 14:19:22 +00003903- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003904 added.
3905
Christian Heimesc94e2b52008-01-14 04:13:37 +00003906- sys.float_info / PyFloat_GetInfo: The floating point information
3907 object was converted from a dict to a specialized structseq object.
3908
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Patch #1816: Added sys.flags structseq. It exposes the status of
3910 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Objects/structseq.c: Implemented new structseq representation. The
3913 patch makes structseqs (e.g. the return value of os.stat) more
3914 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003915
Georg Brandl3ee81df2008-05-17 18:14:43 +00003916- Patch #1700288: added a type attribute cache that caches method

3925 envvar and sys.dont_write_bytecode attribute. All these can be set
3926 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003927
Georg Brandl3ee81df2008-05-17 18:14:43 +00003928- Improve some exception messages when Windows fails to load an
3929 extension module. Now we get for example '%1 is not a valid Win32

Georg Brandl3ee81df2008-05-17 18:14:43 +00003938 and INF. float("nan"), float("inf") and float("-inf") now work on
3939 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003940
Georg Brandl3ee81df2008-05-17 18:14:43 +00003941- Compiler now generates simpler and faster code for dictionary
3942 literals. The oparg for BUILD_MAP now indicates an estimated
3943 dictionary size. There is a new opcode, STORE_MAP, for adding
3944 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003989 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3990 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Issue #1686386: Tuple's tp_repr did not take into account the
3993 possibility of having a self-referential tuple, which is possible
3994 from C code. Nor did object's tp_str consider that a type's tp_str
3995 could do something that could lead to an inifinite recursion.
3996 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3997 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003999- Issue #1164: It was possible to trigger deadlock when using the
4000 'print' statement to write to a file since the GIL was not released
4001 as needed. Now PyObject_Print() does the right thing along with
4002 various tp_print implementations of the built-in types and those in
4003 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004004
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005- Issue #1147: Exceptions were directly allowing string exceptions in
4006 their throw() method even though string exceptions no longer
4007 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004008
Georg Brandl3ee81df2008-05-17 18:14:43 +00004009- Issue #1096: Prevent a segfault from getting the repr of a very
4010 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004011
Brett Cannon1e534b52007-09-07 04:18:30 +00004012- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004013 PyObject_Call() never calling back out to Python code to trigger
4014 recursion depth updates/checks. Required the creation of a static
4015 RuntimeError instance in case normalizing an exception put the
4016 recursion check value past its limit. Fixes crashers
4017 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004032- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004033 __*__ attributes. (Some already existed, e.g., __doc__ and
4034 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004035
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004036- Add -3 option to the interpreter to warn about features that are
4037 deprecated and will be changed/removed in Python 3.0.
4038
Georg Brandl2134e752007-05-21 20:34:16 +00004039- Patch #1686487: you can now pass any mapping after '**' in function
4040 calls.
4041
Collin Winter62903052007-05-18 23:11:24 +00004042- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043 "except E as target:". This is to provide forwards compatibility
4044 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004051- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004052 setting a plain string, ie don't expand to single letter identifiers.
4053
Raymond Hettinger13936692007-04-11 18:40:58 +00004054- Request #1191699: Slices can now be pickled.
4055
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004056- Request #1193128: str.translate() now allows a None argument for
4057 translations that only remove characters without re-mapping the
4058 remaining characters.
4059
Georg Brandl5cb76c12007-03-21 09:00:39 +00004060- Patch #1682205: a TypeError while unpacking an iterable is no longer

4064
Guido van Rossum143b5642007-03-23 04:58:42 +00004065- Bug #1683368: The object.__init__() and object.__new__() methods are
4066 now stricter in rejecting excess arguments. The only time when
4067 either allows excess arguments is when it is not overridden and the
4068 other one is. For backwards compatibility, when both are
4069 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004070 warning later). Also, type.__init__() insists on the same signature
4071 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004072
Georg Brandl3ee81df2008-05-17 18:14:43 +00004073- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4074 object to complex using its __complex__() method before falling back
4075 to the __float__() method. Therefore, the functions in the cmath
4076 module now can operate on objects that define a __complex__()
4077 method.

4088 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004095- Bug #1678647: write a newline after printing an exception in any
4096 case, even when converting the value to a string failed.
4097
Georg Brandl871f1bc2007-03-12 13:17:36 +00004098- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004099 its argument, if it exists. If not, it will work like before. This
4100 allows customizing the output of dir() in the presence of a
4101 __getattr__().

4110 parthensized forms. This means complex(repr(x)) now works instead of
4111 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004112
Georg Brandlaa2321b2007-03-07 00:40:28 +00004113- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114 makes the filenames the warning module prints much more sensible
4115 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004128- Patch #1674228: when assigning a slice (old-style), check for the
4129 sq_ass_slice instead of the sq_slice slot.
4130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- When printing an unraisable error, don't print exceptions. before
4132 the name. This duplicates the behavior whening normally printing
4133 exceptions.

4762 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005043- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5044 with RFC 3207 and forgets any knowledge obtained from the server not
5045 obtained from the TLS negotiation itself. Patch contributed by Bill
5046 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005047
Georg Brandl3ee81df2008-05-17 18:14:43 +00005048- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005049 that the SMTP.starttls() caller no longer needs to call ehlo()
5050 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005051 does not claim to support starttls. Adds the
5052 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5133 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5134 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005151 time so that opening a database previously created with the DB_DUP
5152 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5153 opens. Specifically: dictionary assignment to a DB object will
5154 replace all values for a given key when the database allows
5155 duplicate values. DB users should use DB.put(k, v) when they want
5156 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005157

5163 characters with ASCII value less than 32. Also, it correctly quotes
5164 dots only if they occur on a single line, as opposed to the previous
5165 behavior of quoting dots if they are the second character of any
5166 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005167

5489-----
5490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Unified naming convention for free lists and their limits. All free
5492 lists in Object/ are named ``free_list``, the counter ``numfree``
5493 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5494 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005495
Georg Brandl3ee81df2008-05-17 18:14:43 +00005496- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5497 to ``PyTuple_SetItem``, it can be used to populate a brand new
5498 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005499
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005500- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

5503 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5504 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005505
5506- Patch #1720595: add T_BOOL to the range of structmember types.
5507
5508- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5509 ``PyFloat_GetInfo()`` to the float API.
5510
Georg Brandl3ee81df2008-05-17 18:14:43 +00005511- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5512 of w# format code incorrectly truncated the length to an int, even
5513 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5514 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005515
Georg Brandl3ee81df2008-05-17 18:14:43 +00005516- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5533
5534- Fix some leftovers from the conversion from int to Py_ssize_t
5535 (relevant to strings and sequences of more than 2**31 items).
5536
5537- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5538 outside of pystate.c and should not be necessary.
5539
Georg Brandl3ee81df2008-05-17 18:14:43 +00005540- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5541 absolute imports. In earlier versions they might have used relative
5542 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005543
Georg Brandl3ee81df2008-05-17 18:14:43 +00005544- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5545 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005546
Georg Brandl3ee81df2008-05-17 18:14:43 +00005547- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005554- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5555 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5556 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5557 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005558

Georg Brandl3ee81df2008-05-17 18:14:43 +00005572- Removed the macfs module. It had been deprecated since Python 2.5.
5573 This lead to the deprecation of macostools.touched() as it relied
5574 solely on macfs and was a no-op under OS X.
