404 int.__pow__. These overflow checks were causing int.__pow__ to produce
405 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100406 compiler optimizing the check away. Also fix similar overflow checks
407 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

421 and its type get caught in a reference cycle, and the instance's

Ned Deily0d0ea482012-02-10 12:59:06 +0100483- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
484 Distutils-based packages with C extension modules may fail because
485 Apple has removed gcc-4.2, the version used to build python.org
486 64-bit/32-bit Pythons. If the user does not explicitly override
487 the default C compiler by setting the CC environment variable,
488 Distutils will now attempt to compile extension modules with clang
489 if gcc-4.2 is required but not found. Also as a convenience, if
490 the user does explicitly set CC, substitute its value as the default
491 compiler in the Distutils LDSHARED configuration variable for OS X.
492 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
493 SDK, neither of which are available in Xcode 4. This change does not
494 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700767- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
768 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
769 interpreter process. This could cause failures in non-Distutils subprocesses
770 and was unreliable since tests or user programs could modify the interpreter
771 environment after Distutils set it. Instead, have Distutils set the the
772 deployment target only in the environment of each build subprocess. It is
773 still possible to globally override the default by setting
774 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
775 greater or equal to the default value, the value with which the interpreter
776 was built.

805 updating the check interval, so if the user decreases the check interval,
806 the ticker doesn't have to wind down to zero from the old starting point
807 before the new interval takes effect. And if the user increases the
808 interval, it makes sure the new limit takes effect right away rather have an
809 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001760- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1761 This prevents user-created self-referencing ordered dictionaries from
1762 becoming permanently uncollectable GC garbage. The downside is that
1763 removing __del__ means that the internal doubly-linked list has to wait for
1764 GC collection rather than freeing memory immediately when the refcnt drops
1765 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002224- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2225 start byte and the continuation byte(s) are now considered invalid, instead
2226 of the number of bytes specified by the start byte.
2227 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2228 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2229 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2239 objects. (1) The comparison could incorrectly return True in some cases
2240 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2241 (2) The comparison raised an OverflowError for large integers, leading

2383 non-float non-integer argument is now converted to an integer (if possible)
2384 using its __int__ method. Previously, only small arguments were treated this
2385 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00002436- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2437 operation raises multiple signals and more than one of those signals is
2438 trapped, the specification determines the order in which the signals should be
2439 handled. In many cases this order wasn't being followed, leading to the wrong

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002585 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2586 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2587 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2607Core and Builtins
2608-----------------
2609
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002610- Issue #7301: Add environment variable $PYTHONWARNINGS.
2611
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002612- Issue #8329: Don't return the same lists from select.select when no fds are
2613 changed.
2614
Georg Brandlfee0f442010-05-22 21:26:21 +00002615- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002616 on 64-bit machines. The shift count for either left or right shift is
2617 permitted to be up to sys.maxsize.
2618
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002619- Ensure that tokenization of identifiers is not affected by locale.
2620
Georg Brandlfee0f442010-05-22 21:26:21 +00002621- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002622
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002623- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2624
Georg Brandlfee0f442010-05-22 21:26:21 +00002625- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2626 with a non-empty format string. This is an effort to future-proof user
2627 code. If a derived class does not currently implement __format__ but later
2628 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002629 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002630 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002631
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002632- Issue #8268: Old-style classes (not just instances) now support weak

2641 arguments to a function correct.
2642
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002643- Issue #8164: Don't allow lambda functions to have a docstring.
2644
Victor Stinner66644262010-03-10 22:30:19 +00002645- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002646 (SIGINT). If an error occurs while importing the site module, the error is
2647 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002648 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002661- Issue #8310: Allow dis to examine new style classes.
2662
Georg Brandlfee0f442010-05-22 21:26:21 +00002663- Issue #8257: The Decimal construct now accepts a float instance directly,
2664 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002665
2666 >>> Decimal(1.1)
2667 Decimal('1.100000000000000088817841970012523233890533447265625')
2668
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002669- collections.Counter() now supports a subtract() method.
2670
Georg Brandlfee0f442010-05-22 21:26:21 +00002671- The functools module now has a total_ordering() class decorator to simplify
2672 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002673
Georg Brandlfee0f442010-05-22 21:26:21 +00002674- The functools module also adds cmp_to_key() as a tool to transition old-style
2675 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002676
Georg Brandlfee0f442010-05-22 21:26:21 +00002677- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2678 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002679
Georg Brandlfee0f442010-05-22 21:26:21 +00002680- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2681 InvalidOperation instead of returning False. (Comparisons involving a quiet
2682 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2683 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002684
Georg Brandlfee0f442010-05-22 21:26:21 +00002685- Issue #2531: Comparison operations between floats and Decimal instances now
2686 return a result based on the numeric values of the operands; previously they
2687 returned an arbitrary result based on the relative ordering of id(float) and
2688 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002689
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002690- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002691 argument `-` which tells it to read files to compile from stdin. Each line is
2692 read on demand and the named file is compiled immediately. (Original patch by
2693 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002694
Georg Brandlfee0f442010-05-22 21:26:21 +00002695- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002698- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2699 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002700 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002701
Georg Brandlfee0f442010-05-22 21:26:21 +00002702- Comparisons using one of <, <=, >, >= between a complex instance and a
2703 Fractions instance now raise TypeError instead of returning True/False. This
2704 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2705 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002706

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002716- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002717 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2718 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002719
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002720- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Georg Brandlfee0f442010-05-22 21:26:21 +00002761 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2762 log file to compute the next rollover time. If the log file does not exist,

2807 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00002809- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2810 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2811 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002812 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2813 inconsistent: __int__ was used for some integer codes but not for others, and
2814 the set of integer codes for which it was used differed between native packing
2815 and standard packing.)

3047 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003048 library would return a bogus result; on Solaris, it was possible to crash the
3049 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00003062- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
3063 and add the additional members returned in an OSVERSIONINFOEX structure. The
3064 new members are service_pack_major, service_pack_minor, suite_mask, and
3065 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00003067- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3068 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3069 returning NULL. The macro now returns a statically allocated empty string
3070 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00003071

3080 strings,
3081 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3082 numeric strings corresponding to subnormal values,
3083 (3) a memory leak for some values large enough to cause overflow, and
3084 (4) a number of flaws that could lead to incorrectly rounded results.

3102 interpreter shutdown.
3103
Georg Brandlba83f822010-03-14 09:50:54 +00003104- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

3106 by the XML specification, and are necessary when outputting e.g. PHP code in
3107 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00003115- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003116 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003117 Also, raise ValueError rather than TypeError when an unknown TIPC address
3118 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003122- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003123 file position when calling `truncate()`. It would previously change the file
3124 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003125 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3126
Georg Brandlba83f822010-03-14 09:50:54 +00003127- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3128 class used to represent files stored inside an archive. The new
3129 implementation is significantly faster and can be wrapped in a
3130 ``io.BufferedReader`` object for more speedups. It also solves an issue
3131 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3132 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00003133
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00003134- Issue #7792: Registering non-classes to ABCs raised an obscure error.
3135

3140 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00003141
Georg Brandlba83f822010-03-14 09:50:54 +00003142- Issue #7748: Since unicode values are supported for some metadata options in
3143 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3144 encoded string for them. This ensures that the upload and register commands
3145 send the correct values to PyPI without any error.

3221
Georg Brandlba83f822010-03-14 09:50:54 +00003222- The ``__complex__()`` method is now looked up on the class of instances to
3223 make it consistent with other special methods.

3227
Mark Dickinson1b34d252010-01-01 17:27:30 +00003228- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003229 DeprecationWarning when passed a float argument where an integer was expected.
3230 These functions and methods now raise TypeError instead. The majority of the
3231 effects of this change are in the extension modules, but some core functions
3232 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3233 and many unicode/str methods.

3257
Georg Brandlba83f822010-03-14 09:50:54 +00003258 These executables now work properly with the arch(1) command: ``arch -ppc
3259 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003283 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
3284 alternative to cPickle if you care about performance. Patch by Florent

3399 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3400 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003401
Georg Brandlba83f822010-03-14 09:50:54 +00003402- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3403 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003404
Georg Brandlba83f822010-03-14 09:50:54 +00003405- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3406 1e-100 used to raise OverflowError, but now gives the requested 120
3407 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003416- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3417 decimal string that's guaranteed to round back to x under correct rounding
3418 (with round-half-to-even rounding mode). Previously it gave a string based on
3419 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3420 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3421 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003422
Georg Brandlba83f822010-03-14 09:50:54 +00003423- Issue #7117: On almost all platforms: float-to-string and string-to-float
3424 conversions within Python are now correctly rounded. Places these conversions
3425 occur include: str for floats and complex numbers; the float and complex
3426 constructors; old-style and new-style numeric formatting; serialization and
3427 deserialization of floats and complex numbers using marshal, pickle and json;
3428 parsing of float and imaginary literals in Python code; Decimal-to-float
3429 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003430
Georg Brandlba83f822010-03-14 09:50:54 +00003431 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3432 providing correctly-rounded strtod and dtoa C functions. This code is
3433 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3434 the C compiler. There may be a small number of platforms on which correct
3435 operation of this code cannot be guaranteed, so the code is not used: notably,
3436 this applies to platforms where the C double format is not IEEE 754 binary64,
3437 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3438 and Python's configure script is unable to determine how to change the FPU
3439 precision. On these platforms conversions use the platform strtod and dtoa,
3440 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003441
Georg Brandlba83f822010-03-14 09:50:54 +00003442- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3443 uses the correctly-rounded string <-> float conversions described above (when
3444 available), and so produces correctly rounded results that will display nicely
3445 under the float repr. There are two related small changes: (1) round now
3446 accepts any class with an ``__index__()`` method for its second argument (but
3447 no longer accepts floats for the second argument), and (2) an excessively
3448 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3449 raises an exception.

3598 but with at least one decimal point and with a default precision
3599 of 12. Previously, the behavior the same but with a default precision of 6.
3600 This more closely matches ``str()``, and reduces surprises when adding

3741
Georg Brandlba83f822010-03-14 09:50:54 +00003742- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3743 existing .py counterpart, override the co_filename attributes of all code
3744 objects if the original filename is obsolete (which can happen if the file has
3745 been renamed, moved, or if it is accessed through different paths). Patch by
3746 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00003747
Georg Brandlba83f822010-03-14 09:50:54 +00003748- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.
Martin v. Löwis5344c992009-01-02 20:32:55 +00003749
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00003750- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
3751 file with `str' filename on Windows.
3752
Antoine Pitrouaa687902009-01-01 14:11:22 +00003753- Issue #3680: Reference cycles created through a dict, set or deque iterator
3754 did not get collected.
3755
Georg Brandlba83f822010-03-14 09:50:54 +00003756- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
3757 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00003758
Benjamin Peterson7af65562008-12-29 17:56:58 +00003759- Issue #4764: With io.open, IOError.filename is set when trying to open a
3760 directory on POSIX systems.
3761
Benjamin Petersonfe231b02008-12-29 17:47:42 +00003762- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
3763 systems.
3764
Georg Brandl6425a2f2008-12-28 11:54:53 +00003765- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003766 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003767
Skip Montanarof205c132008-12-23 03:30:15 +00003768- Added test case to ensure attempts to read from a file opened for writing
3769 fail.
3770
Georg Brandlba83f822010-03-14 09:50:54 +00003771- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3772 elapsed times, not only when some objects are uncollectable/unreachable.
3773 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003774
Mark Dickinson1a707982008-12-17 16:14:37 +00003775- Issue #3439: Add a bit_length method to int and long.
3776
Georg Brandlba83f822010-03-14 09:50:54 +00003777- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
3778 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00003779
Georg Brandlba83f822010-03-14 09:50:54 +00003780- Issue #4597: Fixed exception handling when the __exit__ function of a context
3781 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003782
Georg Brandlba83f822010-03-14 09:50:54 +00003783- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003784
Georg Brandlba83f822010-03-14 09:50:54 +00003785- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3786 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3787 instances. On a typical machine this saves 3 bytes of memory (on average) per
3788 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003789
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003790- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3791 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3792 instead of throwing a MemoryError.
3793
Georg Brandlba83f822010-03-14 09:50:54 +00003794- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3795 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003796
Benjamin Petersonc078f922008-11-21 22:27:24 +00003797- Issue #4367: Python would segfault during compiling when the unicodedata
3798 module couldn't be imported and \N escapes were present.
3799
Georg Brandlba83f822010-03-14 09:50:54 +00003800- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3801 file objects with closefd=False. The file descriptor is still kept open but
3802 the file object behaves like a closed file. The ``FileIO`` object also got a
3803 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003804
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003805- Issue #4348: Some bytearray methods returned that didn't cause any change to
3806 the bytearray, returned the same bytearray instead of a copy.
3807
Georg Brandlba83f822010-03-14 09:50:54 +00003808- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00003809
Benjamin Peterson273c2332008-11-17 22:39:09 +00003810- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3811
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003812- Issue #4048: The parser module now correctly validates relative imports.
3813
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003814- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3815 exec statement.
3816
Georg Brandlba83f822010-03-14 09:50:54 +00003817- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3818 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003819
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003820- Issue #4209: Enabling unicode_literals and the print_function in the same
3821 __future__ import didn't work.
3822
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003823- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003824 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003825
Georg Brandlba83f822010-03-14 09:50:54 +00003826- On windows, ``os.chdir()`` given unicode was not working if
3827 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3828 this code path is really executed because I cannot move to such directory on
3829 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003830
Georg Brandlba83f822010-03-14 09:50:54 +00003831- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3832 element is temporarily replaced with an equivalent frozenset. But the
3833 eventual KeyError would always report the empty ``frozenset()`` as the missing
3834 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003835
Georg Brandlba83f822010-03-14 09:50:54 +00003836- Issue #4509: Various issues surrounding resize of bytearray objects to which
3837 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003838
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003839- Issue #4748: Lambda generators no longer return a value.
3840

3842
Gregory P. Smithae91d092009-03-02 05:13:57 +00003843- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3844
Georg Brandlba83f822010-03-14 09:50:54 +00003845- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3846 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003847
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003848- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3849 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003850
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003851- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3852 returned them on 64bit platforms.
3853
Walter Dörwalded960ac2009-05-03 22:36:33 +00003854- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3855 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3856 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3857 of using the replace error handler in PyUnicode_DecodeUTF8().
3858
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003859- Issue #3739: The unicode-internal encoder now reports the number of characters
3860 consumed like any other encoder (instead of the number of bytes).
3861
Georg Brandlba83f822010-03-14 09:50:54 +00003862- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3863 allocator will be automatically disabled when running under Valgrind. This
3864 gives improved memory leak detection when running under Valgrind, while taking
3865 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00003890- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3891 ownership when the group is not forced, because the group may be different
3892 from the user's group and inherit from its container when the test is run.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005107- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5108 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005109 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5110 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00005112- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
5113 regression tests in parallel, shortening the total runtime.
5114
Georg Brandlba83f822010-03-14 09:50:54 +00005115- Issue #5354: New test support function import_fresh_module() makes it easy to
5116 import both normal and optimised versions of modules. test_heapq and
5117 test_warnings have been adjusted to use it, tests for other modules with both
5118 C and Python implementations in the stdlib can be adjusted to use it over
5119 time.

5128 should cause a test to be skipped are now done using import_module from test
5129 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005230- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5231
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005232- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5233 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5234 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5235 ``printf`` function, whereas PyString_FromFormat has an independent
5236 implementation and uses "%zd" on all platforms for size_t values.
5237 This makes a difference on win64, where ``printf`` needs "%Id" to display
5238 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005240- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5244 object; previously an int would be returned for small values. the __long__
5245 method is allowed to return either an int or a long, but the behaviour of
5246 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005248- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005255 was correctly parsed but parsing of subsequent arguments failed.
5256
Vinay Sajip35e3b032008-09-01 14:33:59 +00005257- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005258 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5259 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5260 when given a tuple of classes as second argument, were looking up
5261 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5262 type object.
5263

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005401What's New in Python 2.6 beta 3?
5402================================
5403
Barry Warsaw07a4a382008-08-21 01:15:08 +00005404*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005405
5406Core and Builtins
5407-----------------
5408
Guido van Rossumf8402962008-08-20 15:01:50 +00005409- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5410 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5411 extensions do not automatically benefit from the class attribute
5412 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5413 to their tp_flags field if they care. This is a backwards
5414 compatibility feature; in 3.0, all types will use the cache by
5415 default.
5416
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005417- Keyword arguments can now follow starred arguments. (``f(a, *args,
5418 keyword=23)`` is now valid syntax.)
5419
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005420- ctypes function pointers that are COM methods have a boolean True
5421 value again.
5422
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005423- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5424 by denying s# to parse objects that have a releasebuffer procedure,
5425 and introducing s*.
5426
Georg Brandl1e13ea92008-08-11 09:07:59 +00005427- Issue #3537: Fix an assertion failure when an empty but presized dict
5428 object was stored in the freelist.
5429
Mark Dickinsonb6467572008-08-04 21:30:09 +00005430- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5431 ValueError consistently across platforms.
5432
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005433- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5434 (64bit Unix, for example), unichr() would truncate its argument and return
5435 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5436
Neal Norwitze7d8be82008-07-31 17:17:14 +00005437- Apply security patches from Apple.
5438
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005439- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5440 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5441
Antoine Pitrou92f82162008-07-25 22:22:08 +00005442- Issue #1819: function calls with several named parameters are now on
5443 average 35% faster (as measured by pybench).
5444
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005445- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5446 the python debugger steps into a class statement: the free variables (local
5447 variables defined in an outer scope) would be deleted from the outer scope.
5448
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005449- Issue #2620: Overflow checking when allocating or reallocating memory
5450 was not always being done properly in some python types and extension
5451 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5452 all been updated to perform better checks and places in the code that
5453 would previously leak memory on the error path when such an allocation
5454 failed have been fixed.
5455
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005456Library
5457-------
5458
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005459- Issue #3612: Added some missing basic types in ctypes.wintypes.
5460
Benjamin Petersone977ad42008-08-20 01:42:01 +00005461- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5462 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5463
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005464- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5465 version reported by these tools does not necessarily follow the python
5466 version numbering scheme, so the module is less strict when parsing it.
5467
Nick Coghlanf70385a2008-08-18 12:42:46 +00005468- Issue #2235: Added Py3k warnings for types which will become unhashable
5469 under the stricter __hash__ inheritance rules in 3.0. Several types
5470 which did not meet the rules for hash invariants and were already
5471 unhashable in 3.0 have now been explicitly flagged as unhashable in
5472 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5473 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5474
Brett Cannon88f801d2008-08-18 00:46:22 +00005475- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5476 imported into the module but exposed as part of the module's API.
5477
Brett Cannon7b96f072008-08-18 00:41:11 +00005478- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5479
Brett Cannon46225e72008-08-18 00:36:52 +00005480- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5481
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005482- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5483
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005484- Issue #3575: Incremental decoder's decode function now takes bytearray
5485 by using 's*' instead of 't#'.
5486
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005487- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005488 fails unicode conversion on 2nd parameter. (windows only)
5489
Georg Brandl222e2082010-08-01 22:27:39 +00005490- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005491 in a redirect.
5492
Brett Cannonabe423e2008-08-16 21:47:07 +00005493- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005494 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005495
Facundo Batistaeb90b782008-08-16 14:44:07 +00005496- Issue #2776: fixed small issue when handling an URL with double slash
5497 after a 302 response in the case of not going through a proxy.
5498
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005499- Issue #2676: in the email package, content-type parsing was hanging on
5500 pathological input because of quadratic or exponential behaviour of a
5501 regular expression.
5502
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005503- Issue #3476: binary buffered reading through the new "io" library is now
5504 thread-safe.
5505
Brett Cannonbf3157b2008-08-14 05:00:03 +00005506- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5507 since mimetools itself is deprecated. Because modules are cached, all
5508 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5509
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005510- Issue #3134: shutil referenced undefined WindowsError symbol.
5511
Robert Schuppenies14646332008-08-10 11:01:53 +00005512- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5513 menu entries were not deleted.
5514
Brett Cannon83e81842008-08-09 23:30:55 +00005515- Copied the implementation of reduce() to _functools.reduce() to have a
5516 version that did not raise a DeprecationWarning under -3.
5517
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005518- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5519 a MemoryError rather than silently stop the iteration.
5520
Guido van Rossum59ce9012008-08-09 14:55:34 +00005521- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5522 to _sre.compile() will now be rejected. This should not affect anybody
5523 since the re.compile() function never generates invalid re-bytecode.
5524
Skip Montanaroa032bf42008-08-08 22:52:51 +00005525- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5526 upon first access it can be automatically initialized from the csv file if
5527 it wasn't initialized during instantiation.
5528
Brett Cannon3aa2a492008-08-06 22:28:09 +00005529- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5530 the reload() built-in has been removed.
5531
Brett Cannon7e30b672008-08-04 21:52:25 +00005532- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005533 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005534 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5535 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5536 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5537 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5538 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005539
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005540- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5541 raised an AttributeError.
5542
Benjamin Peterson01a24322008-07-28 23:35:27 +00005543- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005544 asking for a specific length. This problem only affected files opened
5545 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005546
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005547- Issue #3449: Update decimal module to use most recent specification
5548 (v. 1.68) and tests (v. 2.58) from IBM.
5549
Georg Brandl222e2082010-08-01 22:27:39 +00005550- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005551

Raymond Hettinger8c664e82008-07-25 18:43:33 +00005553 on a closed shelf.
5554
Georg Brandlf9efabb2008-07-23 15:16:45 +00005555- Deprecate the "ast" parser function aliases.
5556
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005557- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5558
5559- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5560 invalid arguments.
5561
5562- Issue #3302: Fix several crashes when calling locale's gettext functions
5563 with None arguments.
5564
5565- Issue #3389: Allow resolving dotted names for handlers in logging
5566 configuration files.
5567
5568- Deprecate the sunaudio module for removal in Python 3.0.
5569
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005570- Issue #3394: zipfile.writestr sets external attributes when passed a
5571 file name rather than a ZipInfo instance, so files are extracted with
5572 mode 0600 rather than 000 under Unix.
5573
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005574- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5575 argument in python 2.5, this broke code that subclassed Popen to include its
5576 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5584-------------
5585
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005586- Issue #2235: the C API function PyObject_HashNotImplemented and its
5587 interaction with the tp_hash slot (added in 2.6b2) are now documented
5588
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005589- Issue #643841: The language reference now provides more detailed
5590 coverage of the lookup process for special methods. The disclaimers
5591 regarding lack of coverage of new-style classes have also been
5592 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005595What's New in Python 2.6 beta 2?
5596================================
5597
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005598*Release date: 17-Jul-2008*
5599
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005600Core and Builtins
5601-----------------
5602
Georg Brandl3e483f62008-07-16 22:57:41 +00005603- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5604 its methods now allow for items objects that can be converted to
5605 an integer using operator.index().
5606
Mark Dickinson64b7e502008-07-16 09:40:03 +00005607- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5608 produced a ValueError instead of giving the correct float.
5609
Eric Smitha5fa5a22008-07-16 00:11:49 +00005610- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5611 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5612
Mark Dickinson7103aa42008-07-15 19:08:33 +00005613- Issue #3008: the float type has a new instance method 'float.hex'
5614 and a new class method 'float.fromhex' to convert floating-point
5615 numbers to and from hexadecimal strings, respectively.
5616
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005617- Issue #2235: __hash__ is once again inherited by default. To allow
5618 collections.Hashable to remain meaningful in the presence of the
5619 default hash implementation (object.__hash__), it is now possible
5620 to explicit block inheritance of hash by setting __hash__=None at
5621 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5622 level.
5623
Nick Coghlanb028f502008-07-13 14:52:36 +00005624- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5625 the parent module cannot be found while performing an absolute import.
5626 This means that an incorrectly defined __package__ attribute will
5627 now only prevent relative imports in that module rather than causing
5628 all imports from that module to fail.
5629
Nick Coghlan14ff9942008-07-08 14:21:42 +00005630- Issue #2517: Allow unicode messages in Exceptions again by correctly
5631 bypassing the instance dictionary when looking up __unicode__ on
5632 new-style classes.
5633
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005634- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5635 set to a custom object whose write() method happens to install
5636 another file in sys.stdout.
5637
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005638- Issue #3088: Corrected a race condition in classes derived from
5639 threading.local: the first member set by a thread could be saved in
5640 another thread's dictionary.
5641
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005642- Issue #3004: Minor change to slice.indices(): the start and stop
5643 arguments are now treated identically, making the behaviour easier
5644 to describe and understand. For example, slice(None, -10,
5645 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5646 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5647 10, -1).
5648
Georg Brandl278fc502008-07-19 12:46:12 +00005649- Issue #3219: Calling a function with repeated keyword arguments,
5650 f(a=2, a=23), would not cause a syntax error. This was a regression
5651 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005652
Georg Brandl278fc502008-07-19 12:46:12 +00005653- Issue #2862: Make int and float freelist management consistent with
5654 other freelists. Changes their CompactFreeList apis into
5655 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005656

5658-------
5659
Thomas Heller57adf222008-08-14 19:10:48 +00005660- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5661 api functions without holding the GIL, which could lead to a fatal
5662 error when they failed.
5663
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005664- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005672- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5673 ForkingPickler.register() to resolve conflict with ctypes.
5674
Vinay Sajip51e65192008-07-18 09:01:10 +00005675- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005676
Thomas Heller880f5292008-07-15 19:39:38 +00005677- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5678 a valid dlerror() message.
5679
Thomas Heller2bad6572008-07-15 17:19:50 +00005680- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5681 incomplete structure was created.
5682

6098
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006099- On MacOS X it is now possible to install the framework in 64-bit
6100 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006101 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006102
6103 This is controlled by the configure argument ``--with-universal-archs``:
6104
6105 - ``--with-universal-archs=all``: install 4-way universal
6106
6107 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6108
6109 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6110
6111 This option should be used in combination with ``--enable-universalsdk=``.
6112

6150 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006151
Christian Heimese74c8f22008-04-19 02:23:57 +00006152- Added kill, terminate and send_signal(sig) to subprocess.Popen.
6153

6155 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00006156

Georg Brandl3ee81df2008-05-17 18:14:43 +00006163- Issue #1631171: Re-implement the 'warnings' module in C (the
6164 original Python code has been kept as backup). This will allow for
6165 using the 'warning's machinery in such places as the parser where
6166 use of pure Python code is not possible. Both the ``showarning()``
6167 and ``formatwarning()`` gain an optional 'line' argument which is
6168 not called by default for backwards-compatibility reasons. Setting
6169 ``warnings.showwarning()`` to an implementation that lacks support
6170 for the ``line`` argument will raise a DeprecationWarning.

6194
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006195- The getpass module has been improved on Unix. It now uses /dev/tty
6196 by default and uses stderr instead of stdout. A GetPassWarning is
6197 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00006198

Georg Brandl3ee81df2008-05-17 18:14:43 +00006212- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006213 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006233- Issue #2550: The approach used by client/server code for obtaining
6234 ports to listen on in network-oriented tests has been refined in an
6235 effort to facilitate running multiple instances of the entire
6236 regression test suite in parallel without issue.
6237 test_support.bind_port() has been fixed such that it will always
6238 return a unique port -- which wasn't always the case with the
6239 previous implementation, especially if socket options had been set
6240 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6241 new implementation of bind_port() will actually raise an exception
6242 if it is passed an AF_INET/SOCK_STREAM socket with either the
6243 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6244 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6245 the socket it's been passed. This currently only applies to
6246 Windows. This option prevents any other sockets from binding to the
6247 host/port we've bound to, thus removing the possibility of the
6248 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6249 when a second SOCK_STREAM socket binds and accepts to a host/port
6250 that's already been bound by another socket. The optional preferred
6251 port parameter to bind_port() has been removed. Under no
6252 circumstances should tests be hard coding ports!
6253
6254 test_support.find_unused_port() has also been introduced, which will
6255 pass a temporary socket object to bind_port() in order to obtain an
6256 unused port. The temporary socket object is then closed and
6257 deleted, and the port is returned. This method should only be used
6258 for obtaining an unused port in order to pass to an external program
6259 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6260 a parameter to a server-oriented class that doesn't give you direct
6261 access to the underlying socket used.
6262
6263 Finally, test_support.HOST has been introduced, which should be used
6264 for the host argument of any relevant socket calls (i.e. bind and
6265 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006266
6267 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006269 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6270 test_asynchat and test_socket_ssl.
6271
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272 It is now possible for multiple instances of the regression test
6273 suite to run in parallel without issue.

6540-----------------
6541
Fred Drakea8ee94b2008-03-01 02:45:07 +00006542- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006543 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006544
Georg Brandlad61bc82008-02-23 15:11:18 +00006545- Issue #2067: file.__exit__() now calls subclasses' close() method.
6546
6547- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006548
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006549- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006550 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006551
Eric Smitha73fbe72008-02-23 03:09:44 +00006552- Added the future_builtins module, which contains hex() and oct().
6553 These are the PEP 3127 version of these functions, designed to be
6554 compatible with the hex() and oct() builtins from Python 3.0. They
6555 differ slightly in their output formats from the existing, unchanged
6556 Python 2.6 builtins. The expected usage of the future_builtins
6557 module is:
6558 from future_builtins import hex, oct
6559
Eric Smith7ef40bf2008-02-20 23:34:22 +00006560- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6561 exponents for exponents with absolute value < 100. Follows C99
6562 standard. This is a change on Windows, which would use 3 digits.
6563 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6564 so that any alterations it does to the resulting string will be
6565 available in stringlib/formatter.h (for float.__format__).
6566
Eric Smith5a3c1352008-02-19 13:21:56 +00006567- Implemented PEP 3101, Advanced String Formatting. This adds a new
6568 builtin format(); a format() method for str and unicode; a
6569 __format__() method to object, str, unicode, int, long, float, and
6570 datetime; the class string.Formatter; and the C API
6571 PyObject_Format().
6572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Fixed several potential crashes, all caused by specially crafted
6574 __del__ methods exploiting objects in temporarily inconsistent
6575 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006576
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006577- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006578 prevent a possible crash: an Abstract Base Class would try to access
6579 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006580
Georg Brandl3ee81df2008-05-17 18:14:43 +00006581- Fixed repr() and str() of complex numbers with infinity or nan as
6582 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006583
Georg Brandl3ee81df2008-05-17 18:14:43 +00006584- Clear all free lists during a gc.collect() of the highest generation
6585 in order to allow pymalloc to free more arenas. Python may give back
6586 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006587
Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Issue #2045: Fix an infinite recursion triggered when printing a
6589 subclass of collections.defaultdict, if its default_factory is set
6590 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006591
Christian Heimesf75dbef2008-02-08 00:11:31 +00006592- Fixed a minor memory leak in dictobject.c. The content of the free
6593 list was not freed on interpreter shutdown.
6594
Georg Brandl21e99f42010-03-07 15:23:59 +00006595- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006596 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006597
Georg Brandl3ee81df2008-05-17 18:14:43 +00006598- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6599 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006600 to compact the internal free lists of pre-allocted ints and floats.
6601
Georg Brandl3ee81df2008-05-17 18:14:43 +00006602- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6603 calls. Python expected the return type int but the fork familie
6604 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006605
Georg Brandl3ee81df2008-05-17 18:14:43 +00006606- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6607 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006608
Georg Brandl3ee81df2008-05-17 18:14:43 +00006609- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6610 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006611

Georg Brandl3ee81df2008-05-17 18:14:43 +00006615- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6616 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006617
Georg Brandl3ee81df2008-05-17 18:14:43 +00006618- Patch #1473257: generator objects gain a gi_code attribute. This is
6619 the same object as the func_code attribute of the function that
6620 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006621
Georg Brandl3ee81df2008-05-17 18:14:43 +00006622- Issue #1920: "while 0" statements were completely removed by the
6623 compiler, even in the presence of an "else" clause, which is
6624 supposed to be run when the condition is false. Now the compiler
6625 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006626
Guido van Rossumeead05f2008-01-24 18:21:02 +00006627- A few crashers fixed: weakref_in_del.py (issue #1377858);
6628 loosing_dict_ref.py (issue #1303614, test67.py);
6629 borrowed_ref_[34].py (not in tracker).
6630
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006631- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006632 suppressed while an extension is loaded by calling SetErrorMode in
6633 dynload_win.c. The error is still reported properly.
6634
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006636 several extension methods and modules do not work without unicode
6637 support.
6638
Georg Brandl26543b12008-01-21 18:36:51 +00006639- Issue #1882: when compiling code from a string, encoding cookies in the
6640 second line of code were not always recognized correctly.
6641
Georg Brandl14404b62008-01-19 19:27:05 +00006642- Issue #1679: "0x" was taken as a valid integer literal.
6643
Georg Brandl6caad7d2008-01-26 14:19:22 +00006644- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006645 added.
6646
Christian Heimesc94e2b52008-01-14 04:13:37 +00006647- sys.float_info / PyFloat_GetInfo: The floating point information
6648 object was converted from a dict to a specialized structseq object.
6649
Georg Brandl3ee81df2008-05-17 18:14:43 +00006650- Patch #1816: Added sys.flags structseq. It exposes the status of
6651 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006652
Georg Brandl3ee81df2008-05-17 18:14:43 +00006653- Objects/structseq.c: Implemented new structseq representation. The
6654 patch makes structseqs (e.g. the return value of os.stat) more
6655 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006656
Georg Brandl3ee81df2008-05-17 18:14:43 +00006657- Patch #1700288: added a type attribute cache that caches method
6658 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006659

6666 envvar and sys.dont_write_bytecode attribute. All these can be set
6667 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006668
Georg Brandl3ee81df2008-05-17 18:14:43 +00006669- Improve some exception messages when Windows fails to load an
6670 extension module. Now we get for example '%1 is not a valid Win32
6671 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006678- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006679 and INF. float("nan"), float("inf") and float("-inf") now work on
6680 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006681
Georg Brandl3ee81df2008-05-17 18:14:43 +00006682- Compiler now generates simpler and faster code for dictionary
6683 literals. The oparg for BUILD_MAP now indicates an estimated
6684 dictionary size. There is a new opcode, STORE_MAP, for adding
6685 entries to the dictionary.

6734 possibility of having a self-referential tuple, which is possible
6735 from C code. Nor did object's tp_str consider that a type's tp_str
6736 could do something that could lead to an inifinite recursion.
6737 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6738 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006740- Issue #1164: It was possible to trigger deadlock when using the
6741 'print' statement to write to a file since the GIL was not released
6742 as needed. Now PyObject_Print() does the right thing along with
6743 various tp_print implementations of the built-in types and those in
6744 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006746- Issue #1147: Exceptions were directly allowing string exceptions in
6747 their throw() method even though string exceptions no longer
6748 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006750- Issue #1096: Prevent a segfault from getting the repr of a very
6751 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006752
Brett Cannon1e534b52007-09-07 04:18:30 +00006753- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006754 PyObject_Call() never calling back out to Python code to trigger
6755 recursion depth updates/checks. Required the creation of a static
6756 RuntimeError instance in case normalizing an exception put the
6757 recursion check value past its limit. Fixes crashers
6758 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006773- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006774 __*__ attributes. (Some already existed, e.g., __doc__ and
6775 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006776
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006777- Add -3 option to the interpreter to warn about features that are
6778 deprecated and will be changed/removed in Python 3.0.
6779
Georg Brandl2134e752007-05-21 20:34:16 +00006780- Patch #1686487: you can now pass any mapping after '**' in function
6781 calls.
6782
Collin Winter62903052007-05-18 23:11:24 +00006783- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006784 "except E as target:". This is to provide forwards compatibility
6785 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006786
Brett Cannon229cee22007-05-05 01:34:02 +00006787- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006792- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006793 setting a plain string, ie don't expand to single letter identifiers.
6794
Raymond Hettinger13936692007-04-11 18:40:58 +00006795- Request #1191699: Slices can now be pickled.
6796
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006797- Request #1193128: str.translate() now allows a None argument for
6798 translations that only remove characters without re-mapping the
6799 remaining characters.
6800
Georg Brandl5cb76c12007-03-21 09:00:39 +00006801- Patch #1682205: a TypeError while unpacking an iterable is no longer
6802 masked by a generic one with the message "unpack non-sequence".
6803
Neal Norwitzaa754b72007-03-21 06:39:48 +00006804- Remove unused file Python/fmod.c.
6805
Guido van Rossum143b5642007-03-23 04:58:42 +00006806- Bug #1683368: The object.__init__() and object.__new__() methods are
6807 now stricter in rejecting excess arguments. The only time when
6808 either allows excess arguments is when it is not overridden and the
6809 other one is. For backwards compatibility, when both are
6810 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006811 warning later). Also, type.__init__() insists on the same signature
6812 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006813
Georg Brandl3ee81df2008-05-17 18:14:43 +00006814- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6815 object to complex using its __complex__() method before falling back
6816 to the __float__() method. Therefore, the functions in the cmath
6817 module now can operate on objects that define a __complex__()
6818 method.

6829 its type.

6835
Georg Brandl7b9c5552007-03-12 14:30:05 +00006836- Bug #1678647: write a newline after printing an exception in any
6837 case, even when converting the value to a string failed.
6838
Georg Brandl871f1bc2007-03-12 13:17:36 +00006839- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840 its argument, if it exists. If not, it will work like before. This
6841 allows customizing the output of dir() in the presence of a
6842 __getattr__().

6851 parthensized forms. This means complex(repr(x)) now works instead of
6852 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006853
Georg Brandlaa2321b2007-03-07 00:40:28 +00006854- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006855 makes the filenames the warning module prints much more sensible
6856 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006857

Georg Brandl0fca97a2007-03-05 22:28:08 +00006869- Patch #1674228: when assigning a slice (old-style), check for the
6870 sq_ass_slice instead of the sq_slice slot.
6871
Georg Brandl3ee81df2008-05-17 18:14:43 +00006872- When printing an unraisable error, don't print exceptions. before
6873 the name. This duplicates the behavior whening normally printing
6874 exceptions.

7785 with RFC 3207 and forgets any knowledge obtained from the server not
7786 obtained from the TLS negotiation itself. Patch contributed by Bill
7787 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007788
Georg Brandl3ee81df2008-05-17 18:14:43 +00007789- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007790 that the SMTP.starttls() caller no longer needs to call ehlo()
7791 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007792 does not claim to support starttls. Adds the
7793 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7874 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7875 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007892 time so that opening a database previously created with the DB_DUP
7893 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7894 opens. Specifically: dictionary assignment to a DB object will
7895 replace all values for a given key when the database allows
7896 duplicate values. DB users should use DB.put(k, v) when they want
7897 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007898

7904 characters with ASCII value less than 32. Also, it correctly quotes
7905 dots only if they occur on a single line, as opposed to the previous
7906 behavior of quoting dots if they are the second character of any
7907 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007908

8230-----
8231
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232- Unified naming convention for free lists and their limits. All free
8233 lists in Object/ are named ``free_list``, the counter ``numfree``
8234 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8235 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008236
Georg Brandl3ee81df2008-05-17 18:14:43 +00008237- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8238 to ``PyTuple_SetItem``, it can be used to populate a brand new
8239 frozenset; but it does not steal a reference to the added item.

8248
8249- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8250 ``PyFloat_GetInfo()`` to the float API.
8251
Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8253 of w# format code incorrectly truncated the length to an int, even
8254 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8255 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008257- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8258 Py_TYPE and Py_REFCNT.

8275- Fix some leftovers from the conversion from int to Py_ssize_t
8276 (relevant to strings and sequences of more than 2**31 items).
8277
8278- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8279 outside of pystate.c and should not be necessary.
8280
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8282 absolute imports. In earlier versions they might have used relative
8283 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008284
Georg Brandl3ee81df2008-05-17 18:14:43 +00008285- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8286 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008287
Georg Brandl3ee81df2008-05-17 18:14:43 +00008288- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008295- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8296 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8297 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8298 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008299

Georg Brandl3ee81df2008-05-17 18:14:43 +00008313- Removed the macfs module. It had been deprecated since Python 2.5.
8314 This lead to the deprecation of macostools.touched() as it relied
8315 solely on macfs and was a no-op under OS X.
