401 int.__pow__. These overflow checks were causing int.__pow__ to produce
402 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100403 compiler optimizing the check away. Also fix similar overflow checks
404 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +0100480- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
481 Distutils-based packages with C extension modules may fail because
482 Apple has removed gcc-4.2, the version used to build python.org
483 64-bit/32-bit Pythons. If the user does not explicitly override
484 the default C compiler by setting the CC environment variable,
485 Distutils will now attempt to compile extension modules with clang
486 if gcc-4.2 is required but not found. Also as a convenience, if
487 the user does explicitly set CC, substitute its value as the default
488 compiler in the Distutils LDSHARED configuration variable for OS X.
489 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
490 SDK, neither of which are available in Xcode 4. This change does not
491 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700764- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
765 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
766 interpreter process. This could cause failures in non-Distutils subprocesses
767 and was unreliable since tests or user programs could modify the interpreter
768 environment after Distutils set it. Instead, have Distutils set the the
769 deployment target only in the environment of each build subprocess. It is
770 still possible to globally override the default by setting
771 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
772 greater or equal to the default value, the value with which the interpreter
773 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001757- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1758 This prevents user-created self-referencing ordered dictionaries from
1759 becoming permanently uncollectable GC garbage. The downside is that
1760 removing __del__ means that the internal doubly-linked list has to wait for
1761 GC collection rather than freeing memory immediately when the refcnt drops
1762 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002221- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2222 start byte and the continuation byte(s) are now considered invalid, instead
2223 of the number of bytes specified by the start byte.
2224 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2225 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2226 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2236 objects. (1) The comparison could incorrectly return True in some cases
2237 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2238 (2) The comparison raised an OverflowError for large integers, leading

2380 non-float non-integer argument is now converted to an integer (if possible)
2381 using its __int__ method. Previously, only small arguments were treated this
2382 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00002433- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2434 operation raises multiple signals and more than one of those signals is
2435 trapped, the specification determines the order in which the signals should be
2436 handled. In many cases this order wasn't being followed, leading to the wrong
2437 Python exception being raised.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002582 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2583 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2584 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00002603
2604Core and Builtins
2605-----------------
2606
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002607- Issue #7301: Add environment variable $PYTHONWARNINGS.
2608
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002609- Issue #8329: Don't return the same lists from select.select when no fds are
2610 changed.
2611
Georg Brandlfee0f442010-05-22 21:26:21 +00002612- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002613 on 64-bit machines. The shift count for either left or right shift is
2614 permitted to be up to sys.maxsize.
2615
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002616- Ensure that tokenization of identifiers is not affected by locale.
2617
Georg Brandlfee0f442010-05-22 21:26:21 +00002618- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002619
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002620- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2621
Georg Brandlfee0f442010-05-22 21:26:21 +00002622- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2623 with a non-empty format string. This is an effort to future-proof user
2624 code. If a derived class does not currently implement __format__ but later
2625 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002626 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002627 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002628
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002629- Issue #8268: Old-style classes (not just instances) now support weak

2638 arguments to a function correct.
2639
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002640- Issue #8164: Don't allow lambda functions to have a docstring.
2641
Victor Stinner66644262010-03-10 22:30:19 +00002642- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002643 (SIGINT). If an error occurs while importing the site module, the error is
2644 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002645 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002658- Issue #8310: Allow dis to examine new style classes.
2659
Georg Brandlfee0f442010-05-22 21:26:21 +00002660- Issue #8257: The Decimal construct now accepts a float instance directly,
2661 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002662
2663 >>> Decimal(1.1)
2664 Decimal('1.100000000000000088817841970012523233890533447265625')
2665
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002666- collections.Counter() now supports a subtract() method.
2667
Georg Brandlfee0f442010-05-22 21:26:21 +00002668- The functools module now has a total_ordering() class decorator to simplify
2669 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002670
Georg Brandlfee0f442010-05-22 21:26:21 +00002671- The functools module also adds cmp_to_key() as a tool to transition old-style
2672 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002673
Georg Brandlfee0f442010-05-22 21:26:21 +00002674- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2675 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002676
Georg Brandlfee0f442010-05-22 21:26:21 +00002677- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2678 InvalidOperation instead of returning False. (Comparisons involving a quiet
2679 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2680 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002681
Georg Brandlfee0f442010-05-22 21:26:21 +00002682- Issue #2531: Comparison operations between floats and Decimal instances now
2683 return a result based on the numeric values of the operands; previously they
2684 returned an arbitrary result based on the relative ordering of id(float) and
2685 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002686
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002687- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002688 argument `-` which tells it to read files to compile from stdin. Each line is
2689 read on demand and the named file is compiled immediately. (Original patch by
2690 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002691
Georg Brandlfee0f442010-05-22 21:26:21 +00002692- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002695- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2696 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002697 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002698
Georg Brandlfee0f442010-05-22 21:26:21 +00002699- Comparisons using one of <, <=, >, >= between a complex instance and a
2700 Fractions instance now raise TypeError instead of returning True/False. This
2701 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2702 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002703

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002713- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002714 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2715 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002716
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002717- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

2804 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00002806- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2807 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2808 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002809 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2810 inconsistent: __int__ was used for some integer codes but not for others, and
2811 the set of integer codes for which it was used differed between native packing
2812 and standard packing.)

3044 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003045 library would return a bogus result; on Solaris, it was possible to crash the
3046 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00003059- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
3060 and add the additional members returned in an OSVERSIONINFOEX structure. The
3061 new members are service_pack_major, service_pack_minor, suite_mask, and
3062 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00003064- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3065 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3066 returning NULL. The macro now returns a statically allocated empty string
3067 instead.

3077 strings,
3078 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3079 numeric strings corresponding to subnormal values,
3080 (3) a memory leak for some values large enough to cause overflow, and
3081 (4) a number of flaws that could lead to incorrectly rounded results.

3099 interpreter shutdown.
3100
Georg Brandlba83f822010-03-14 09:50:54 +00003101- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

3103 by the XML specification, and are necessary when outputting e.g. PHP code in
3104 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00003112- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003113 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003114 Also, raise ValueError rather than TypeError when an unknown TIPC address
3115 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003119- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003120 file position when calling `truncate()`. It would previously change the file
3121 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003122 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3123
Georg Brandlba83f822010-03-14 09:50:54 +00003124- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3125 class used to represent files stored inside an archive. The new
3126 implementation is significantly faster and can be wrapped in a
3127 ``io.BufferedReader`` object for more speedups. It also solves an issue
3128 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3129 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00003130
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00003131- Issue #7792: Registering non-classes to ABCs raised an obscure error.

3137 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00003138
Georg Brandlba83f822010-03-14 09:50:54 +00003139- Issue #7748: Since unicode values are supported for some metadata options in
3140 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3141 encoded string for them. This ensures that the upload and register commands
3142 send the correct values to PyPI without any error.

3218
Georg Brandlba83f822010-03-14 09:50:54 +00003219- The ``__complex__()`` method is now looked up on the class of instances to
3220 make it consistent with other special methods.

3224
Mark Dickinson1b34d252010-01-01 17:27:30 +00003225- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003226 DeprecationWarning when passed a float argument where an integer was expected.
3227 These functions and methods now raise TypeError instead. The majority of the
3228 effects of this change are in the extension modules, but some core functions
3229 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3230 and many unicode/str methods.

3254
Georg Brandlba83f822010-03-14 09:50:54 +00003255 These executables now work properly with the arch(1) command: ``arch -ppc
3256 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003280 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
3281 alternative to cPickle if you care about performance. Patch by Florent

3396 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3397 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003398
Georg Brandlba83f822010-03-14 09:50:54 +00003399- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3400 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003401
Georg Brandlba83f822010-03-14 09:50:54 +00003402- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3403 1e-100 used to raise OverflowError, but now gives the requested 120
3404 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003412
Georg Brandlba83f822010-03-14 09:50:54 +00003413- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3414 decimal string that's guaranteed to round back to x under correct rounding
3415 (with round-half-to-even rounding mode). Previously it gave a string based on
3416 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3417 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3418 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003419
Georg Brandlba83f822010-03-14 09:50:54 +00003420- Issue #7117: On almost all platforms: float-to-string and string-to-float
3421 conversions within Python are now correctly rounded. Places these conversions
3422 occur include: str for floats and complex numbers; the float and complex
3423 constructors; old-style and new-style numeric formatting; serialization and
3424 deserialization of floats and complex numbers using marshal, pickle and json;
3425 parsing of float and imaginary literals in Python code; Decimal-to-float
3426 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003427
Georg Brandlba83f822010-03-14 09:50:54 +00003428 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3429 providing correctly-rounded strtod and dtoa C functions. This code is
3430 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3431 the C compiler. There may be a small number of platforms on which correct
3432 operation of this code cannot be guaranteed, so the code is not used: notably,
3433 this applies to platforms where the C double format is not IEEE 754 binary64,
3434 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3435 and Python's configure script is unable to determine how to change the FPU
3436 precision. On these platforms conversions use the platform strtod and dtoa,
3437 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003438
Georg Brandlba83f822010-03-14 09:50:54 +00003439- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3440 uses the correctly-rounded string <-> float conversions described above (when
3441 available), and so produces correctly rounded results that will display nicely
3442 under the float repr. There are two related small changes: (1) round now
3443 accepts any class with an ``__index__()`` method for its second argument (but
3444 no longer accepts floats for the second argument), and (2) an excessively
3445 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3446 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003450- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00003593- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3594 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3595 but with at least one decimal point and with a default precision
3596 of 12. Previously, the behavior the same but with a default precision of 6.
3597 This more closely matches ``str()``, and reduces surprises when adding
3598 alignment flags to the empty presentation type. This also affects the new
3599 complex.__format__ in the same way.

3738
Georg Brandlba83f822010-03-14 09:50:54 +00003739- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3740 existing .py counterpart, override the co_filename attributes of all code
3741 objects if the original filename is obsolete (which can happen if the file has
3742 been renamed, moved, or if it is accessed through different paths). Patch by
3743 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00003744
Georg Brandlba83f822010-03-14 09:50:54 +00003745- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.
Martin v. Löwis5344c992009-01-02 20:32:55 +00003746
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00003747- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
3748 file with `str' filename on Windows.
3749
Antoine Pitrouaa687902009-01-01 14:11:22 +00003750- Issue #3680: Reference cycles created through a dict, set or deque iterator
3751 did not get collected.
3752
Georg Brandlba83f822010-03-14 09:50:54 +00003753- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
3754 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00003755
Benjamin Peterson7af65562008-12-29 17:56:58 +00003756- Issue #4764: With io.open, IOError.filename is set when trying to open a
3757 directory on POSIX systems.
3758
Benjamin Petersonfe231b02008-12-29 17:47:42 +00003759- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
3760 systems.
3761
Georg Brandl6425a2f2008-12-28 11:54:53 +00003762- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003763 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003764
Skip Montanarof205c132008-12-23 03:30:15 +00003765- Added test case to ensure attempts to read from a file opened for writing
3766 fail.
3767
Georg Brandlba83f822010-03-14 09:50:54 +00003768- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3769 elapsed times, not only when some objects are uncollectable/unreachable.
3770 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003771
Mark Dickinson1a707982008-12-17 16:14:37 +00003772- Issue #3439: Add a bit_length method to int and long.
3773
Georg Brandlba83f822010-03-14 09:50:54 +00003774- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
3775 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00003776
Georg Brandlba83f822010-03-14 09:50:54 +00003777- Issue #4597: Fixed exception handling when the __exit__ function of a context
3778 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003779
Georg Brandlba83f822010-03-14 09:50:54 +00003780- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003781
Georg Brandlba83f822010-03-14 09:50:54 +00003782- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3783 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3784 instances. On a typical machine this saves 3 bytes of memory (on average) per
3785 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003786
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003787- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3788 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3789 instead of throwing a MemoryError.
3790
Georg Brandlba83f822010-03-14 09:50:54 +00003791- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3792 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003793
Benjamin Petersonc078f922008-11-21 22:27:24 +00003794- Issue #4367: Python would segfault during compiling when the unicodedata
3795 module couldn't be imported and \N escapes were present.
3796
Georg Brandlba83f822010-03-14 09:50:54 +00003797- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3798 file objects with closefd=False. The file descriptor is still kept open but
3799 the file object behaves like a closed file. The ``FileIO`` object also got a
3800 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003801
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003802- Issue #4348: Some bytearray methods returned that didn't cause any change to
3803 the bytearray, returned the same bytearray instead of a copy.
3804
Georg Brandlba83f822010-03-14 09:50:54 +00003805- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00003807- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3808
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003809- Issue #4048: The parser module now correctly validates relative imports.
3810
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003811- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3812 exec statement.
3813
Georg Brandlba83f822010-03-14 09:50:54 +00003814- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3815 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003816
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003817- Issue #4209: Enabling unicode_literals and the print_function in the same
3818 __future__ import didn't work.
3819
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003820- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003821 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003822
Georg Brandlba83f822010-03-14 09:50:54 +00003823- On windows, ``os.chdir()`` given unicode was not working if
3824 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3825 this code path is really executed because I cannot move to such directory on
3826 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003827
Georg Brandlba83f822010-03-14 09:50:54 +00003828- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3829 element is temporarily replaced with an equivalent frozenset. But the
3830 eventual KeyError would always report the empty ``frozenset()`` as the missing
3831 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003832
Georg Brandlba83f822010-03-14 09:50:54 +00003833- Issue #4509: Various issues surrounding resize of bytearray objects to which
3834 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003835
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003836- Issue #4748: Lambda generators no longer return a value.
3837

3839
Gregory P. Smithae91d092009-03-02 05:13:57 +00003840- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3841
Georg Brandlba83f822010-03-14 09:50:54 +00003842- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3843 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003844
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003845- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3846 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003847
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003848- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3849 returned them on 64bit platforms.
3850
Walter Dörwalded960ac2009-05-03 22:36:33 +00003851- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3852 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3853 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3854 of using the replace error handler in PyUnicode_DecodeUTF8().
3855
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003856- Issue #3739: The unicode-internal encoder now reports the number of characters
3857 consumed like any other encoder (instead of the number of bytes).
3858
Georg Brandlba83f822010-03-14 09:50:54 +00003859- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3860 allocator will be automatically disabled when running under Valgrind. This
3861 gives improved memory leak detection when running under Valgrind, while taking
3862 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00003887- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3888 ownership when the group is not forced, because the group may be different
3889 from the user's group and inherit from its container when the test is run.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005104- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5105 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005106 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5107 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00005112- Issue #5354: New test support function import_fresh_module() makes it easy to
5113 import both normal and optimised versions of modules. test_heapq and
5114 test_warnings have been adjusted to use it, tests for other modules with both
5115 C and Python implementations in the stdlib can be adjusted to use it over
5116 time.

5125 should cause a test to be skipped are now done using import_module from test
5126 support, which does the conversion.

5228
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005229- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5230 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5231 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5232 ``printf`` function, whereas PyString_FromFormat has an independent
5233 implementation and uses "%zd" on all platforms for size_t values.
5234 This makes a difference on win64, where ``printf`` needs "%Id" to display
5235 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005237- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5241 object; previously an int would be returned for small values. the __long__
5242 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005252 was correctly parsed but parsing of subsequent arguments failed.
5253
Vinay Sajip35e3b032008-09-01 14:33:59 +00005254- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005255 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5256 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5257 when given a tuple of classes as second argument, were looking up
5258 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5259 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005398What's New in Python 2.6 beta 3?
5399================================
5400
Barry Warsaw07a4a382008-08-21 01:15:08 +00005401*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005402
5403Core and Builtins
5404-----------------
5405
Guido van Rossumf8402962008-08-20 15:01:50 +00005406- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5407 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5408 extensions do not automatically benefit from the class attribute
5409 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5410 to their tp_flags field if they care. This is a backwards
5411 compatibility feature; in 3.0, all types will use the cache by
5412 default.
5413
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005414- Keyword arguments can now follow starred arguments. (``f(a, *args,
5415 keyword=23)`` is now valid syntax.)
5416
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005417- ctypes function pointers that are COM methods have a boolean True
5418 value again.
5419
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005420- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5421 by denying s# to parse objects that have a releasebuffer procedure,
5422 and introducing s*.
5423
Georg Brandl1e13ea92008-08-11 09:07:59 +00005424- Issue #3537: Fix an assertion failure when an empty but presized dict
5425 object was stored in the freelist.
5426
Mark Dickinsonb6467572008-08-04 21:30:09 +00005427- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5428 ValueError consistently across platforms.
5429
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005430- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5431 (64bit Unix, for example), unichr() would truncate its argument and return
5432 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5433
Neal Norwitze7d8be82008-07-31 17:17:14 +00005434- Apply security patches from Apple.
5435
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005436- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5437 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5438
Antoine Pitrou92f82162008-07-25 22:22:08 +00005439- Issue #1819: function calls with several named parameters are now on
5440 average 35% faster (as measured by pybench).
5441
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005442- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5443 the python debugger steps into a class statement: the free variables (local
5444 variables defined in an outer scope) would be deleted from the outer scope.
5445
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005446- Issue #2620: Overflow checking when allocating or reallocating memory
5447 was not always being done properly in some python types and extension
5448 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5449 all been updated to perform better checks and places in the code that
5450 would previously leak memory on the error path when such an allocation
5451 failed have been fixed.
5452
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005453Library
5454-------
5455
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005456- Issue #3612: Added some missing basic types in ctypes.wintypes.
5457
Benjamin Petersone977ad42008-08-20 01:42:01 +00005458- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5459 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5460
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005461- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5462 version reported by these tools does not necessarily follow the python
5463 version numbering scheme, so the module is less strict when parsing it.
5464
Nick Coghlanf70385a2008-08-18 12:42:46 +00005465- Issue #2235: Added Py3k warnings for types which will become unhashable
5466 under the stricter __hash__ inheritance rules in 3.0. Several types
5467 which did not meet the rules for hash invariants and were already
5468 unhashable in 3.0 have now been explicitly flagged as unhashable in
5469 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5470 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5471
Brett Cannon88f801d2008-08-18 00:46:22 +00005472- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5473 imported into the module but exposed as part of the module's API.
5474
Brett Cannon7b96f072008-08-18 00:41:11 +00005475- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5476
Brett Cannon46225e72008-08-18 00:36:52 +00005477- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5478
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005479- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5480
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005481- Issue #3575: Incremental decoder's decode function now takes bytearray
5482 by using 's*' instead of 't#'.
5483
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005484- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005485 fails unicode conversion on 2nd parameter. (windows only)
5486
Georg Brandl222e2082010-08-01 22:27:39 +00005487- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005488 in a redirect.
5489
Brett Cannonabe423e2008-08-16 21:47:07 +00005490- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005491 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005492
Facundo Batistaeb90b782008-08-16 14:44:07 +00005493- Issue #2776: fixed small issue when handling an URL with double slash
5494 after a 302 response in the case of not going through a proxy.
5495
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005496- Issue #2676: in the email package, content-type parsing was hanging on
5497 pathological input because of quadratic or exponential behaviour of a
5498 regular expression.
5499
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005500- Issue #3476: binary buffered reading through the new "io" library is now
5501 thread-safe.
5502
Brett Cannonbf3157b2008-08-14 05:00:03 +00005503- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5504 since mimetools itself is deprecated. Because modules are cached, all
5505 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5506
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005507- Issue #3134: shutil referenced undefined WindowsError symbol.
5508
Robert Schuppenies14646332008-08-10 11:01:53 +00005509- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5510 menu entries were not deleted.
5511
Brett Cannon83e81842008-08-09 23:30:55 +00005512- Copied the implementation of reduce() to _functools.reduce() to have a
5513 version that did not raise a DeprecationWarning under -3.
5514
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005515- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5516 a MemoryError rather than silently stop the iteration.
5517
Guido van Rossum59ce9012008-08-09 14:55:34 +00005518- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5519 to _sre.compile() will now be rejected. This should not affect anybody
5520 since the re.compile() function never generates invalid re-bytecode.
5521
Skip Montanaroa032bf42008-08-08 22:52:51 +00005522- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5523 upon first access it can be automatically initialized from the csv file if
5524 it wasn't initialized during instantiation.
5525
Brett Cannon3aa2a492008-08-06 22:28:09 +00005526- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5527 the reload() built-in has been removed.
5528
Brett Cannon7e30b672008-08-04 21:52:25 +00005529- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005530 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005531 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5532 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5533 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5534 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5535 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005536
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005537- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5538 raised an AttributeError.
5539
Benjamin Peterson01a24322008-07-28 23:35:27 +00005540- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005541 asking for a specific length. This problem only affected files opened
5542 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005543
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005544- Issue #3449: Update decimal module to use most recent specification
5545 (v. 1.68) and tests (v. 2.58) from IBM.
5546
Georg Brandl222e2082010-08-01 22:27:39 +00005547- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005548

Raymond Hettinger8c664e82008-07-25 18:43:33 +00005550 on a closed shelf.
5551
Georg Brandlf9efabb2008-07-23 15:16:45 +00005552- Deprecate the "ast" parser function aliases.
5553
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005554- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5555
5556- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5557 invalid arguments.
5558
5559- Issue #3302: Fix several crashes when calling locale's gettext functions
5560 with None arguments.
5561
5562- Issue #3389: Allow resolving dotted names for handlers in logging
5563 configuration files.
5564
5565- Deprecate the sunaudio module for removal in Python 3.0.
5566
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005567- Issue #3394: zipfile.writestr sets external attributes when passed a
5568 file name rather than a ZipInfo instance, so files are extracted with
5569 mode 0600 rather than 000 under Unix.
5570
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005571- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5572 argument in python 2.5, this broke code that subclassed Popen to include its
5573 own poll method. Fixed my moving _deadstate to an _internal_poll method.
5574
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00005575Build
5576-----

5581-------------
5582
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005583- Issue #2235: the C API function PyObject_HashNotImplemented and its
5584 interaction with the tp_hash slot (added in 2.6b2) are now documented
5585
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005586- Issue #643841: The language reference now provides more detailed
5587 coverage of the lookup process for special methods. The disclaimers
5588 regarding lack of coverage of new-style classes have also been
5589 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005592What's New in Python 2.6 beta 2?
5593================================
5594
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005595*Release date: 17-Jul-2008*
5596
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005597Core and Builtins
5598-----------------
5599
Georg Brandl3e483f62008-07-16 22:57:41 +00005600- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5601 its methods now allow for items objects that can be converted to
5602 an integer using operator.index().
5603
Mark Dickinson64b7e502008-07-16 09:40:03 +00005604- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5605 produced a ValueError instead of giving the correct float.
5606
Eric Smitha5fa5a22008-07-16 00:11:49 +00005607- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5608 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5609
Mark Dickinson7103aa42008-07-15 19:08:33 +00005610- Issue #3008: the float type has a new instance method 'float.hex'
5611 and a new class method 'float.fromhex' to convert floating-point
5612 numbers to and from hexadecimal strings, respectively.
5613
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005614- Issue #2235: __hash__ is once again inherited by default. To allow
5615 collections.Hashable to remain meaningful in the presence of the
5616 default hash implementation (object.__hash__), it is now possible
5617 to explicit block inheritance of hash by setting __hash__=None at
5618 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5619 level.
5620
Nick Coghlanb028f502008-07-13 14:52:36 +00005621- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5622 the parent module cannot be found while performing an absolute import.
5623 This means that an incorrectly defined __package__ attribute will
5624 now only prevent relative imports in that module rather than causing
5625 all imports from that module to fail.
5626
Nick Coghlan14ff9942008-07-08 14:21:42 +00005627- Issue #2517: Allow unicode messages in Exceptions again by correctly
5628 bypassing the instance dictionary when looking up __unicode__ on
5629 new-style classes.
5630
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005631- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5632 set to a custom object whose write() method happens to install
5633 another file in sys.stdout.
5634
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005635- Issue #3088: Corrected a race condition in classes derived from
5636 threading.local: the first member set by a thread could be saved in
5637 another thread's dictionary.
5638
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005639- Issue #3004: Minor change to slice.indices(): the start and stop
5640 arguments are now treated identically, making the behaviour easier
5641 to describe and understand. For example, slice(None, -10,
5642 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5643 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5644 10, -1).
5645
Georg Brandl278fc502008-07-19 12:46:12 +00005646- Issue #3219: Calling a function with repeated keyword arguments,
5647 f(a=2, a=23), would not cause a syntax error. This was a regression
5648 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005649
Georg Brandl278fc502008-07-19 12:46:12 +00005650- Issue #2862: Make int and float freelist management consistent with
5651 other freelists. Changes their CompactFreeList apis into
5652 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005653

5655-------
5656
Thomas Heller57adf222008-08-14 19:10:48 +00005657- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5658 api functions without holding the GIL, which could lead to a fatal
5659 error when they failed.
5660
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005661- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005669- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5670 ForkingPickler.register() to resolve conflict with ctypes.
5671
Vinay Sajip51e65192008-07-18 09:01:10 +00005672- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00005674- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5675 a valid dlerror() message.
5676
Thomas Heller2bad6572008-07-15 17:19:50 +00005677- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5678 incomplete structure was created.
5679

6097 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006098 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006099
6100 This is controlled by the configure argument ``--with-universal-archs``:
6101
6102 - ``--with-universal-archs=all``: install 4-way universal
6103
6104 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6105
6106 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6107
6108 This option should be used in combination with ``--enable-universalsdk=``.

6147 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006148
Christian Heimese74c8f22008-04-19 02:23:57 +00006149- Added kill, terminate and send_signal(sig) to subprocess.Popen.

6152 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00006153

Georg Brandl3ee81df2008-05-17 18:14:43 +00006160- Issue #1631171: Re-implement the 'warnings' module in C (the
6161 original Python code has been kept as backup). This will allow for
6162 using the 'warning's machinery in such places as the parser where
6163 use of pure Python code is not possible. Both the ``showarning()``
6164 and ``formatwarning()`` gain an optional 'line' argument which is
6165 not called by default for backwards-compatibility reasons. Setting
6166 ``warnings.showwarning()`` to an implementation that lacks support
6167 for the ``line`` argument will raise a DeprecationWarning.

6191
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006192- The getpass module has been improved on Unix. It now uses /dev/tty
6193 by default and uses stderr instead of stdout. A GetPassWarning is
6194 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00006195

Georg Brandl3ee81df2008-05-17 18:14:43 +00006209- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006210 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006230- Issue #2550: The approach used by client/server code for obtaining
6231 ports to listen on in network-oriented tests has been refined in an
6232 effort to facilitate running multiple instances of the entire
6233 regression test suite in parallel without issue.
6234 test_support.bind_port() has been fixed such that it will always
6235 return a unique port -- which wasn't always the case with the
6236 previous implementation, especially if socket options had been set
6237 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6238 new implementation of bind_port() will actually raise an exception
6239 if it is passed an AF_INET/SOCK_STREAM socket with either the
6240 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6241 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6242 the socket it's been passed. This currently only applies to
6243 Windows. This option prevents any other sockets from binding to the
6244 host/port we've bound to, thus removing the possibility of the
6245 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6246 when a second SOCK_STREAM socket binds and accepts to a host/port
6247 that's already been bound by another socket. The optional preferred
6248 port parameter to bind_port() has been removed. Under no
6249 circumstances should tests be hard coding ports!
6250
6251 test_support.find_unused_port() has also been introduced, which will
6252 pass a temporary socket object to bind_port() in order to obtain an
6253 unused port. The temporary socket object is then closed and
6254 deleted, and the port is returned. This method should only be used
6255 for obtaining an unused port in order to pass to an external program
6256 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6257 a parameter to a server-oriented class that doesn't give you direct
6258 access to the underlying socket used.
6259
6260 Finally, test_support.HOST has been introduced, which should be used
6261 for the host argument of any relevant socket calls (i.e. bind and
6262 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006263
6264 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006265 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006266 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6267 test_asynchat and test_socket_ssl.
6268
Georg Brandl3ee81df2008-05-17 18:14:43 +00006269 It is now possible for multiple instances of the regression test
6270 suite to run in parallel without issue.

6537-----------------
6538
Fred Drakea8ee94b2008-03-01 02:45:07 +00006539- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006540 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006541
Georg Brandlad61bc82008-02-23 15:11:18 +00006542- Issue #2067: file.__exit__() now calls subclasses' close() method.
6543
6544- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006545
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006546- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006547 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006548
Eric Smitha73fbe72008-02-23 03:09:44 +00006549- Added the future_builtins module, which contains hex() and oct().
6550 These are the PEP 3127 version of these functions, designed to be
6551 compatible with the hex() and oct() builtins from Python 3.0. They
6552 differ slightly in their output formats from the existing, unchanged
6553 Python 2.6 builtins. The expected usage of the future_builtins
6554 module is:
6555 from future_builtins import hex, oct
6556
Eric Smith7ef40bf2008-02-20 23:34:22 +00006557- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6558 exponents for exponents with absolute value < 100. Follows C99
6559 standard. This is a change on Windows, which would use 3 digits.
6560 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6561 so that any alterations it does to the resulting string will be
6562 available in stringlib/formatter.h (for float.__format__).
6563
Eric Smith5a3c1352008-02-19 13:21:56 +00006564- Implemented PEP 3101, Advanced String Formatting. This adds a new
6565 builtin format(); a format() method for str and unicode; a
6566 __format__() method to object, str, unicode, int, long, float, and
6567 datetime; the class string.Formatter; and the C API
6568 PyObject_Format().
6569
Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- Fixed several potential crashes, all caused by specially crafted
6571 __del__ methods exploiting objects in temporarily inconsistent
6572 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006573
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006574- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575 prevent a possible crash: an Abstract Base Class would try to access
6576 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006577
Georg Brandl3ee81df2008-05-17 18:14:43 +00006578- Fixed repr() and str() of complex numbers with infinity or nan as
6579 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006580
Georg Brandl3ee81df2008-05-17 18:14:43 +00006581- Clear all free lists during a gc.collect() of the highest generation
6582 in order to allow pymalloc to free more arenas. Python may give back
6583 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006584
Georg Brandl3ee81df2008-05-17 18:14:43 +00006585- Issue #2045: Fix an infinite recursion triggered when printing a
6586 subclass of collections.defaultdict, if its default_factory is set
6587 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006588
Christian Heimesf75dbef2008-02-08 00:11:31 +00006589- Fixed a minor memory leak in dictobject.c. The content of the free
6590 list was not freed on interpreter shutdown.
6591
Georg Brandl21e99f42010-03-07 15:23:59 +00006592- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006594
Georg Brandl3ee81df2008-05-17 18:14:43 +00006595- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6596 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006597 to compact the internal free lists of pre-allocted ints and floats.
6598
Georg Brandl3ee81df2008-05-17 18:14:43 +00006599- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6600 calls. Python expected the return type int but the fork familie
6601 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6604 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006605
Georg Brandl3ee81df2008-05-17 18:14:43 +00006606- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6607 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006612- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6613 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006614
Georg Brandl3ee81df2008-05-17 18:14:43 +00006615- Patch #1473257: generator objects gain a gi_code attribute. This is
6616 the same object as the func_code attribute of the function that
6617 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006618
Georg Brandl3ee81df2008-05-17 18:14:43 +00006619- Issue #1920: "while 0" statements were completely removed by the
6620 compiler, even in the presence of an "else" clause, which is
6621 supposed to be run when the condition is false. Now the compiler
6622 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006623
Guido van Rossumeead05f2008-01-24 18:21:02 +00006624- A few crashers fixed: weakref_in_del.py (issue #1377858);
6625 loosing_dict_ref.py (issue #1303614, test67.py);
6626 borrowed_ref_[34].py (not in tracker).
6627
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006628- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006629 suppressed while an extension is loaded by calling SetErrorMode in
6630 dynload_win.c. The error is still reported properly.
6631
Georg Brandl3ee81df2008-05-17 18:14:43 +00006632- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006633 several extension methods and modules do not work without unicode
6634 support.
6635
Georg Brandl26543b12008-01-21 18:36:51 +00006636- Issue #1882: when compiling code from a string, encoding cookies in the
6637 second line of code were not always recognized correctly.
6638
Georg Brandl14404b62008-01-19 19:27:05 +00006639- Issue #1679: "0x" was taken as a valid integer literal.
6640
Georg Brandl6caad7d2008-01-26 14:19:22 +00006641- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006642 added.
6643
Christian Heimesc94e2b52008-01-14 04:13:37 +00006644- sys.float_info / PyFloat_GetInfo: The floating point information
6645 object was converted from a dict to a specialized structseq object.
6646
Georg Brandl3ee81df2008-05-17 18:14:43 +00006647- Patch #1816: Added sys.flags structseq. It exposes the status of
6648 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006649
Georg Brandl3ee81df2008-05-17 18:14:43 +00006650- Objects/structseq.c: Implemented new structseq representation. The
6651 patch makes structseqs (e.g. the return value of os.stat) more
6652 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006653
Georg Brandl3ee81df2008-05-17 18:14:43 +00006654- Patch #1700288: added a type attribute cache that caches method
6655 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006656
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006657- Bug #1776: __import__() no longer accepts filenames on any platform.

6663 envvar and sys.dont_write_bytecode attribute. All these can be set
6664 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006665
Georg Brandl3ee81df2008-05-17 18:14:43 +00006666- Improve some exception messages when Windows fails to load an
6667 extension module. Now we get for example '%1 is not a valid Win32
6668 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006675- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006676 and INF. float("nan"), float("inf") and float("-inf") now work on
6677 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006678
Georg Brandl3ee81df2008-05-17 18:14:43 +00006679- Compiler now generates simpler and faster code for dictionary
6680 literals. The oparg for BUILD_MAP now indicates an estimated
6681 dictionary size. There is a new opcode, STORE_MAP, for adding
6682 entries to the dictionary.

6731 possibility of having a self-referential tuple, which is possible
6732 from C code. Nor did object's tp_str consider that a type's tp_str
6733 could do something that could lead to an inifinite recursion.
6734 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6735 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006737- Issue #1164: It was possible to trigger deadlock when using the
6738 'print' statement to write to a file since the GIL was not released
6739 as needed. Now PyObject_Print() does the right thing along with
6740 various tp_print implementations of the built-in types and those in
6741 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006742
Georg Brandl3ee81df2008-05-17 18:14:43 +00006743- Issue #1147: Exceptions were directly allowing string exceptions in
6744 their throw() method even though string exceptions no longer
6745 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006746
Georg Brandl3ee81df2008-05-17 18:14:43 +00006747- Issue #1096: Prevent a segfault from getting the repr of a very
6748 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006749
Brett Cannon1e534b52007-09-07 04:18:30 +00006750- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006751 PyObject_Call() never calling back out to Python code to trigger
6752 recursion depth updates/checks. Required the creation of a static
6753 RuntimeError instance in case normalizing an exception put the
6754 recursion check value past its limit. Fixes crashers
6755 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006770- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006771 __*__ attributes. (Some already existed, e.g., __doc__ and
6772 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006773
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006774- Add -3 option to the interpreter to warn about features that are
6775 deprecated and will be changed/removed in Python 3.0.
6776
Georg Brandl2134e752007-05-21 20:34:16 +00006777- Patch #1686487: you can now pass any mapping after '**' in function
6778 calls.
6779
Collin Winter62903052007-05-18 23:11:24 +00006780- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006781 "except E as target:". This is to provide forwards compatibility
6782 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006783
Brett Cannon229cee22007-05-05 01:34:02 +00006784- Deprecate BaseException.message as per PEP 352.
6785
Georg Brandl3ee81df2008-05-17 18:14:43 +00006786- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00006789- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006790 setting a plain string, ie don't expand to single letter identifiers.
6791
Raymond Hettinger13936692007-04-11 18:40:58 +00006792- Request #1191699: Slices can now be pickled.
6793
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006794- Request #1193128: str.translate() now allows a None argument for
6795 translations that only remove characters without re-mapping the
6796 remaining characters.
6797
Georg Brandl5cb76c12007-03-21 09:00:39 +00006798- Patch #1682205: a TypeError while unpacking an iterable is no longer
6799 masked by a generic one with the message "unpack non-sequence".
6800
Neal Norwitzaa754b72007-03-21 06:39:48 +00006801- Remove unused file Python/fmod.c.
6802
Guido van Rossum143b5642007-03-23 04:58:42 +00006803- Bug #1683368: The object.__init__() and object.__new__() methods are
6804 now stricter in rejecting excess arguments. The only time when
6805 either allows excess arguments is when it is not overridden and the
6806 other one is. For backwards compatibility, when both are
6807 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006808 warning later). Also, type.__init__() insists on the same signature
6809 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006810
Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6812 object to complex using its __complex__() method before falling back
6813 to the __float__() method. Therefore, the functions in the cmath
6814 module now can operate on objects that define a __complex__()
6815 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006816

6826 its type.

6832
Georg Brandl7b9c5552007-03-12 14:30:05 +00006833- Bug #1678647: write a newline after printing an exception in any
6834 case, even when converting the value to a string failed.
6835
Georg Brandl871f1bc2007-03-12 13:17:36 +00006836- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006837 its argument, if it exists. If not, it will work like before. This
6838 allows customizing the output of dir() in the presence of a
6839 __getattr__().

6848 parthensized forms. This means complex(repr(x)) now works instead of
6849 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006850
Georg Brandlaa2321b2007-03-07 00:40:28 +00006851- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006852 makes the filenames the warning module prints much more sensible
6853 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006854
Georg Brandl49aafc92007-03-07 00:34:46 +00006855- Variant of patch #697613: don't exit the interpreter on a SystemExit
6856 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006857 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00006866- Patch #1674228: when assigning a slice (old-style), check for the
6867 sq_ass_slice instead of the sq_slice slot.
6868
Georg Brandl3ee81df2008-05-17 18:14:43 +00006869- When printing an unraisable error, don't print exceptions. before
6870 the name. This duplicates the behavior whening normally printing
6871 exceptions.

7500 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007781- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7782 with RFC 3207 and forgets any knowledge obtained from the server not
7783 obtained from the TLS negotiation itself. Patch contributed by Bill
7784 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007785
Georg Brandl3ee81df2008-05-17 18:14:43 +00007786- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007787 that the SMTP.starttls() caller no longer needs to call ehlo()
7788 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007789 does not claim to support starttls. Adds the
7790 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7871 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7872 silently miscode subclasses of those types. Now, it raises a
7873 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007874

Georg Brandl3ee81df2008-05-17 18:14:43 +00007889 time so that opening a database previously created with the DB_DUP
7890 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7891 opens. Specifically: dictionary assignment to a DB object will
7892 replace all values for a given key when the database allows
7893 duplicate values. DB users should use DB.put(k, v) when they want
7894 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007895

7901 characters with ASCII value less than 32. Also, it correctly quotes
7902 dots only if they occur on a single line, as opposed to the previous
7903 behavior of quoting dots if they are the second character of any
7904 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007905

8227-----
8228
Georg Brandl3ee81df2008-05-17 18:14:43 +00008229- Unified naming convention for free lists and their limits. All free
8230 lists in Object/ are named ``free_list``, the counter ``numfree``
8231 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8232 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008233
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8235 to ``PyTuple_SetItem``, it can be used to populate a brand new
8236 frozenset; but it does not steal a reference to the added item.

8241 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8242 PyLong_FromSsize_t public functions.

8244- Patch #1720595: add T_BOOL to the range of structmember types.
8245
8246- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8247 ``PyFloat_GetInfo()`` to the float API.
8248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8250 of w# format code incorrectly truncated the length to an int, even
8251 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8252 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008253
Georg Brandl3ee81df2008-05-17 18:14:43 +00008254- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8255 Py_TYPE and Py_REFCNT.

8271
8272- Fix some leftovers from the conversion from int to Py_ssize_t
8273 (relevant to strings and sequences of more than 2**31 items).
8274
8275- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8276 outside of pystate.c and should not be necessary.
8277
Georg Brandl3ee81df2008-05-17 18:14:43 +00008278- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8279 absolute imports. In earlier versions they might have used relative
8280 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008281
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8283 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008284
Georg Brandl3ee81df2008-05-17 18:14:43 +00008285- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008292- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8293 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8294 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8295 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008296

Georg Brandl3ee81df2008-05-17 18:14:43 +00008310- Removed the macfs module. It had been deprecated since Python 2.5.
8311 This lead to the deprecation of macostools.touched() as it relied
8312 solely on macfs and was a no-op under OS X.
