Mark Dickinsondbbed042011-09-19 16:38:08 +0100641- Issue #12973: Fix overflow checks that invoked undefined behaviour in
642 int.__pow__. These overflow checks were causing int.__pow__ to produce
643 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100644 compiler optimizing the check away. Also fix similar overflow checks
645 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
646 bugs caused test failures with recent versions of Clang.

659 and its type get caught in a reference cycle, and the instance's
660 deallocator calls one of the methods on the type (e.g. when subclassing

Ned Deily0d0ea482012-02-10 12:59:06 +0100721- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
722 Distutils-based packages with C extension modules may fail because
723 Apple has removed gcc-4.2, the version used to build python.org
724 64-bit/32-bit Pythons. If the user does not explicitly override
725 the default C compiler by setting the CC environment variable,
726 Distutils will now attempt to compile extension modules with clang
727 if gcc-4.2 is required but not found. Also as a convenience, if
728 the user does explicitly set CC, substitute its value as the default
729 compiler in the Distutils LDSHARED configuration variable for OS X.
730 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
731 SDK, neither of which are available in Xcode 4. This change does not
732 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001005- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1006 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1007 interpreter process. This could cause failures in non-Distutils subprocesses
1008 and was unreliable since tests or user programs could modify the interpreter
1009 environment after Distutils set it. Instead, have Distutils set the the
1010 deployment target only in the environment of each build subprocess. It is
1011 still possible to globally override the default by setting
1012 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1013 greater or equal to the default value, the value with which the interpreter
1014 was built.

1043 updating the check interval, so if the user decreases the check interval,
1044 the ticker doesn't have to wind down to zero from the old starting point
1045 before the new interval takes effect. And if the user increases the
1046 interval, it makes sure the new limit takes effect right away rather have an
1047 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002462- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2463 start byte and the continuation byte(s) are now considered invalid, instead
2464 of the number of bytes specified by the start byte.
2465 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2466 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2467 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002476- Issue #8748: Fix two issues with comparisons between complex and integer
2477 objects. (1) The comparison could incorrectly return True in some cases
2478 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2479 (2) The comparison raised an OverflowError for large integers, leading
2480 to unpredictable exceptions when combining integers and complex objects
2481 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002483- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002620- Issue #1533: Fix inconsistency in range function argument processing: any
2621 non-float non-integer argument is now converted to an integer (if possible)
2622 using its __int__ method. Previously, only small arguments were treated this
2623 way; larger arguments (those whose __int__ was outside the range of a C long)
2624 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00002632 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002633 benefit compared to the dynamic memory allocation fallback. Patch by
2634 Charles-François Natali.

2659 messages when accessing undefined class attributes because of the cheap
2660 inheritance with the underlying socket object. The cheap inheritance has been
2661 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00002662

Georg Brandlfee0f442010-05-22 21:26:21 +00002674- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2675 operation raises multiple signals and more than one of those signals is
2676 trapped, the specification determines the order in which the signals should be
2677 handled. In many cases this order wasn't being followed, leading to the wrong
2678 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00002679

2846-----------------
2847
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002848- Issue #7301: Add environment variable $PYTHONWARNINGS.
2849
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002850- Issue #8329: Don't return the same lists from select.select when no fds are
2851 changed.
2852
Georg Brandlfee0f442010-05-22 21:26:21 +00002853- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002854 on 64-bit machines. The shift count for either left or right shift is
2855 permitted to be up to sys.maxsize.
2856
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002857- Ensure that tokenization of identifiers is not affected by locale.
2858
Georg Brandlfee0f442010-05-22 21:26:21 +00002859- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002860
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002861- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2862
Georg Brandlfee0f442010-05-22 21:26:21 +00002863- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2864 with a non-empty format string. This is an effort to future-proof user
2865 code. If a derived class does not currently implement __format__ but later
2866 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002867 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002868 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002869
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002870- Issue #8268: Old-style classes (not just instances) now support weak
2871 references.
2872
Georg Brandlfee0f442010-05-22 21:26:21 +00002873- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2874 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002875
Victor Stinnerc7790ed2010-03-22 12:36:28 +00002876- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00002877
Benjamin Peterson96545892010-03-21 20:21:00 +00002878- Issue #6474: Make error message from passing an inadequate number of keyword
2879 arguments to a function correct.
2880
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002881- Issue #8164: Don't allow lambda functions to have a docstring.
2882
Victor Stinner66644262010-03-10 22:30:19 +00002883- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002884 (SIGINT). If an error occurs while importing the site module, the error is
2885 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002886 module.
2887
Collin Winter001a3952010-03-18 21:54:01 +00002888- Code objects now support weak references.

2891-------
2892
R. David Murray661303f2010-04-13 20:57:40 +00002893- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
2894
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002895- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002896 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2897 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002898
Benjamin Peterson76a23c12010-04-04 23:23:22 +00002899- Issue #8310: Allow dis to examine new style classes.
2900
Georg Brandlfee0f442010-05-22 21:26:21 +00002901- Issue #8257: The Decimal construct now accepts a float instance directly,
2902 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002903
2904 >>> Decimal(1.1)
2905 Decimal('1.100000000000000088817841970012523233890533447265625')
2906
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002907- collections.Counter() now supports a subtract() method.
2908
Georg Brandlfee0f442010-05-22 21:26:21 +00002909- The functools module now has a total_ordering() class decorator to simplify
2910 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002911
Georg Brandlfee0f442010-05-22 21:26:21 +00002912- The functools module also adds cmp_to_key() as a tool to transition old-style
2913 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002914
Georg Brandlfee0f442010-05-22 21:26:21 +00002915- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2916 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002917
Georg Brandlfee0f442010-05-22 21:26:21 +00002918- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2919 InvalidOperation instead of returning False. (Comparisons involving a quiet
2920 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2921 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002922
Georg Brandlfee0f442010-05-22 21:26:21 +00002923- Issue #2531: Comparison operations between floats and Decimal instances now
2924 return a result based on the numeric values of the operands; previously they
2925 returned an arbitrary result based on the relative ordering of id(float) and
2926 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002927
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002928- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002929 argument `-` which tells it to read files to compile from stdin. Each line is
2930 read on demand and the named file is compiled immediately. (Original patch by
2931 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002932
Georg Brandlfee0f442010-05-22 21:26:21 +00002933- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2934 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002936- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2937 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002938 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002939
Georg Brandlfee0f442010-05-22 21:26:21 +00002940- Comparisons using one of <, <=, >, >= between a complex instance and a
2941 Fractions instance now raise TypeError instead of returning True/False. This
2942 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2943 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002944

2953
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002954- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002955 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2956 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002957
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002958- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2959 deprecated.
2960
Georg Brandlfee0f442010-05-22 21:26:21 +00002961- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2962 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002963

2968 existing at the same time, causing a Unicode error when configuration code
2969 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002970

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002998- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002999 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3000 log file to compute the next rollover time. If the log file does not exist,
3001 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003002

3010
Georg Brandlba83f822010-03-14 09:50:54 +00003011- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3012 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3013 This is a behavior change, so email's minor version number is now bumped, to
3014 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003042- Issue #8300: When passing a non-integer argument to struct.pack with any
3043 integer format code, struct.pack first attempts to convert the non-integer
3044 using its __index__ method. If that method is non-existent or raises
3045 TypeError it goes on to try the __int__ method, as described below.
3046
Georg Brandlba83f822010-03-14 09:50:54 +00003047- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3048 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3049 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003050 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3051 inconsistent: __int__ was used for some integer codes but not for others, and
3052 the set of integer codes for which it was used differed between native packing
3053 and standard packing.)

3457Core and Builtins
3458-----------------
3459
Georg Brandlba83f822010-03-14 09:50:54 +00003460- The ``__complex__()`` method is now looked up on the class of instances to
3461 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003463- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3464 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3465
Mark Dickinson1b34d252010-01-01 17:27:30 +00003466- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003467 DeprecationWarning when passed a float argument where an integer was expected.
3468 These functions and methods now raise TypeError instead. The majority of the
3469 effects of this change are in the extension modules, but some core functions
3470 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3471 and many unicode/str methods.

3482 used to drop the time part of the result.
3483
Georg Brandlba83f822010-03-14 09:50:54 +00003484- Issue #1811: Improve accuracy and cross-platform consistency for true division
3485 of integers: the result of a/b is now correctly rounded for ints a and b (at
3486 least on IEEE 754 platforms), and in particular does not depend on the
3487 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003488

3495
Georg Brandlba83f822010-03-14 09:50:54 +00003496 These executables now work properly with the arch(1) command: ``arch -ppc
3497 python`` will start a universal binary version of python in PPC mode (unlike
3498 previous releases).

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003639

Georg Brandlba83f822010-03-14 09:50:54 +00003654- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3655 decimal string that's guaranteed to round back to x under correct rounding
3656 (with round-half-to-even rounding mode). Previously it gave a string based on
3657 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3658 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3659 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003660
Georg Brandlba83f822010-03-14 09:50:54 +00003661- Issue #7117: On almost all platforms: float-to-string and string-to-float
3662 conversions within Python are now correctly rounded. Places these conversions
3663 occur include: str for floats and complex numbers; the float and complex
3664 constructors; old-style and new-style numeric formatting; serialization and
3665 deserialization of floats and complex numbers using marshal, pickle and json;
3666 parsing of float and imaginary literals in Python code; Decimal-to-float
3667 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003668
Georg Brandlba83f822010-03-14 09:50:54 +00003669 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3670 providing correctly-rounded strtod and dtoa C functions. This code is
3671 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3672 the C compiler. There may be a small number of platforms on which correct
3673 operation of this code cannot be guaranteed, so the code is not used: notably,
3674 this applies to platforms where the C double format is not IEEE 754 binary64,
3675 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3676 and Python's configure script is unable to determine how to change the FPU
3677 precision. On these platforms conversions use the platform strtod and dtoa,
3678 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003680- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3681 uses the correctly-rounded string <-> float conversions described above (when
3682 available), and so produces correctly rounded results that will display nicely
3683 under the float repr. There are two related small changes: (1) round now
3684 accepts any class with an ``__index__()`` method for its second argument (but
3685 no longer accepts floats for the second argument), and (2) an excessively
3686 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3687 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003829
Georg Brandlba83f822010-03-14 09:50:54 +00003830 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3831 (2) parsing of strings representing infinities and nans was locale aware; and
3832 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003833
Georg Brandlba83f822010-03-14 09:50:54 +00003834- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3835 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3836 but with at least one decimal point and with a default precision
3837 of 12. Previously, the behavior the same but with a default precision of 6.
3838 This more closely matches ``str()``, and reduces surprises when adding
3839 alignment flags to the empty presentation type. This also affects the new
3840 complex.__format__ in the same way.
3841
3842- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3843 classtype's, even if it was None. property now inserts the __doc__ into the
3844 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003904- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003905 untrackable objects are not tracked by the garbage collector. This can reduce
3906 the size of collections and therefore the garbage collection overhead on

3914 internal representation of integers, for performance reasons. Base 2**30 is
3915 enabled by default on 64-bit machines. Add --enable-big-digits option to
3916 configure, which overrides the default. Add sys.long_info structseq to
3917 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004018- Issue #4597: Fixed exception handling when the __exit__ function of a context
4019 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00004020
Georg Brandlba83f822010-03-14 09:50:54 +00004021- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00004022
Georg Brandlba83f822010-03-14 09:50:54 +00004023- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4024 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4025 instances. On a typical machine this saves 3 bytes of memory (on average) per
4026 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004027
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004028- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4029 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4030 instead of throwing a MemoryError.
4031
Georg Brandlba83f822010-03-14 09:50:54 +00004032- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4033 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004034
Benjamin Petersonc078f922008-11-21 22:27:24 +00004035- Issue #4367: Python would segfault during compiling when the unicodedata
4036 module couldn't be imported and \N escapes were present.
4037
Georg Brandlba83f822010-03-14 09:50:54 +00004038- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4039 file objects with closefd=False. The file descriptor is still kept open but
4040 the file object behaves like a closed file. The ``FileIO`` object also got a
4041 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004042
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004043- Issue #4348: Some bytearray methods returned that didn't cause any change to
4044 the bytearray, returned the same bytearray instead of a copy.
4045
Georg Brandlba83f822010-03-14 09:50:54 +00004046- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00004047
Benjamin Peterson273c2332008-11-17 22:39:09 +00004048- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4049
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004050- Issue #4048: The parser module now correctly validates relative imports.
4051
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004052- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4053 exec statement.
4054
Georg Brandlba83f822010-03-14 09:50:54 +00004055- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4056 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004057
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004058- Issue #4209: Enabling unicode_literals and the print_function in the same
4059 __future__ import didn't work.
4060
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004061- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004062 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004063
Georg Brandlba83f822010-03-14 09:50:54 +00004064- On windows, ``os.chdir()`` given unicode was not working if
4065 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4066 this code path is really executed because I cannot move to such directory on
4067 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004068
Georg Brandlba83f822010-03-14 09:50:54 +00004069- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4070 element is temporarily replaced with an equivalent frozenset. But the
4071 eventual KeyError would always report the empty ``frozenset()`` as the missing
4072 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004073
Georg Brandlba83f822010-03-14 09:50:54 +00004074- Issue #4509: Various issues surrounding resize of bytearray objects to which
4075 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00004076
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00004077- Issue #4748: Lambda generators no longer return a value.
4078
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00004079- Issue #3582: Use native TLS functions on Windows
4080
Gregory P. Smithae91d092009-03-02 05:13:57 +00004081- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
4082
Georg Brandlba83f822010-03-14 09:50:54 +00004083- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
4084 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00004085
Matthias Klose91a3b9e2009-04-05 21:19:13 +00004086- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4087 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004088
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004089- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4090 returned them on 64bit platforms.
4091
Walter Dörwalded960ac2009-05-03 22:36:33 +00004092- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4093 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4094 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4095 of using the replace error handler in PyUnicode_DecodeUTF8().
4096
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004097- Issue #3739: The unicode-internal encoder now reports the number of characters
4098 consumed like any other encoder (instead of the number of bytes).
4099
Georg Brandlba83f822010-03-14 09:50:54 +00004100- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4101 allocator will be automatically disabled when running under Valgrind. This
4102 gives improved memory leak detection when running under Valgrind, while taking
4103 advantage of pymalloc at other times.

Antoine Pitrou30b3b352009-12-02 20:37:54 +00004127
Tarek Ziadéa5076a22009-11-29 22:20:30 +00004128- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
4129 ownership when the group is not forced, because the group may be different
4130 from the user's group and inherit from its container when the test is run.
4131

Georg Brandlba83f822010-03-14 09:50:54 +00004172- Issue #6816: runpy now provides a run_path function that allows Python code to
4173 execute file paths that refer to source or compiled Python files as well as
4174 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00004175 __main__.py file. This allows applications that run other Python scripts to
4176 support the same flexibility as the CPython command line itself.
4177
Georg Brandlba83f822010-03-14 09:50:54 +00004178- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
4179 connection with another process, rather than looping endlessly. The default
4180 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +00004197 a modification is done through it. This fixes inconsistencies and test

5270 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5271 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005468- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5469
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005470- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5471 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5472 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5473 ``printf`` function, whereas PyString_FromFormat has an independent
5474 implementation and uses "%zd" on all platforms for size_t values.
5475 This makes a difference on win64, where ``printf`` needs "%Id" to display
5476 64bit values.
5477
Benjamin Peterson97179b02008-09-09 20:55:01 +00005478- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5482 object; previously an int would be returned for small values. the __long__
5483 method is allowed to return either an int or a long, but the behaviour of
5484 float objects should not change to respect backward compatibility.
5485
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005486- Issue #3751: str.rpartition would perform a left-partition when called with
5487 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005492 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005493 was correctly parsed but parsing of subsequent arguments failed.
5494
Vinay Sajip35e3b032008-09-01 14:33:59 +00005495- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005496 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5497 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5498 when given a tuple of classes as second argument, were looking up
5499 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5500 type object.
5501
Neal Norwitz18aa3882008-08-24 05:04:52 +00005502- Fix crashes on memory allocation failure found with failmalloc.
5503
5504- Fix memory leaks found with valgrind and update suppressions file.
5505
5506- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005571 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5572 for catch_warnings() also led to an improvement in the raising of a

5645-----------------
5646
Guido van Rossumf8402962008-08-20 15:01:50 +00005647- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5648 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5649 extensions do not automatically benefit from the class attribute
5650 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5651 to their tp_flags field if they care. This is a backwards
5652 compatibility feature; in 3.0, all types will use the cache by
5653 default.
5654
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005655- Keyword arguments can now follow starred arguments. (``f(a, *args,
5656 keyword=23)`` is now valid syntax.)
5657
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005658- ctypes function pointers that are COM methods have a boolean True
5659 value again.
5660
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005661- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5662 by denying s# to parse objects that have a releasebuffer procedure,
5663 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00005665- Issue #3537: Fix an assertion failure when an empty but presized dict
5666 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00005668- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5669 ValueError consistently across platforms.
5670
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005671- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5672 (64bit Unix, for example), unichr() would truncate its argument and return
5673 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5674
Neal Norwitze7d8be82008-07-31 17:17:14 +00005675- Apply security patches from Apple.
5676
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005677- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00005680- Issue #1819: function calls with several named parameters are now on
5681 average 35% faster (as measured by pybench).
5682
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005683- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5684 the python debugger steps into a class statement: the free variables (local
5685 variables defined in an outer scope) would be deleted from the outer scope.
5686
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005687- Issue #2620: Overflow checking when allocating or reallocating memory
5688 was not always being done properly in some python types and extension
5689 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5690 all been updated to perform better checks and places in the code that
5691 would previously leak memory on the error path when such an allocation
5692 failed have been fixed.

5698
Benjamin Petersone977ad42008-08-20 01:42:01 +00005699- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5700 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5701
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005702- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5703 version reported by these tools does not necessarily follow the python
5704 version numbering scheme, so the module is less strict when parsing it.
5705
Nick Coghlanf70385a2008-08-18 12:42:46 +00005706- Issue #2235: Added Py3k warnings for types which will become unhashable
5707 under the stricter __hash__ inheritance rules in 3.0. Several types
5708 which did not meet the rules for hash invariants and were already
5709 unhashable in 3.0 have now been explicitly flagged as unhashable in
5710 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5711 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5712
Brett Cannon88f801d2008-08-18 00:46:22 +00005713- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5714 imported into the module but exposed as part of the module's API.
5715

5742 thread-safe.
5743
Brett Cannonbf3157b2008-08-14 05:00:03 +00005744- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5745 since mimetools itself is deprecated. Because modules are cached, all
5746 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5747
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005748- Issue #3134: shutil referenced undefined WindowsError symbol.

5755
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005756- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5757 a MemoryError rather than silently stop the iteration.
5758
Guido van Rossum59ce9012008-08-09 14:55:34 +00005759- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5760 to _sre.compile() will now be rejected. This should not affect anybody
5761 since the re.compile() function never generates invalid re-bytecode.
5762
Skip Montanaroa032bf42008-08-08 22:52:51 +00005763- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5764 upon first access it can be automatically initialized from the csv file if
5765 it wasn't initialized during instantiation.
5766
Brett Cannon3aa2a492008-08-06 22:28:09 +00005767- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5768 the reload() built-in has been removed.
5769
Brett Cannon7e30b672008-08-04 21:52:25 +00005770- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005771 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5779 raised an AttributeError.
5780
Benjamin Peterson01a24322008-07-28 23:35:27 +00005781- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005782 asking for a specific length. This problem only affected files opened
5783 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005784

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005808- Issue #3394: zipfile.writestr sets external attributes when passed a
5809 file name rather than a ZipInfo instance, so files are extracted with
5810 mode 0600 rather than 000 under Unix.
5811
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005812- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5813 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005824- Issue #2235: the C API function PyObject_HashNotImplemented and its
5825 interaction with the tp_hash slot (added in 2.6b2) are now documented
5826
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005827- Issue #643841: The language reference now provides more detailed
5828 coverage of the lookup process for special methods. The disclaimers
5829 regarding lack of coverage of new-style classes have also been
5830 removed, since the coverage is now fairly reasonable.

5834================================
5835
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005836*Release date: 17-Jul-2008*
5837
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005838Core and Builtins
5839-----------------
5840
Georg Brandl3e483f62008-07-16 22:57:41 +00005841- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5842 its methods now allow for items objects that can be converted to
5843 an integer using operator.index().
5844
Mark Dickinson64b7e502008-07-16 09:40:03 +00005845- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5846 produced a ValueError instead of giving the correct float.
5847
Eric Smitha5fa5a22008-07-16 00:11:49 +00005848- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5849 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5850
Mark Dickinson7103aa42008-07-15 19:08:33 +00005851- Issue #3008: the float type has a new instance method 'float.hex'
5852 and a new class method 'float.fromhex' to convert floating-point
5853 numbers to and from hexadecimal strings, respectively.
5854
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005855- Issue #2235: __hash__ is once again inherited by default. To allow
5856 collections.Hashable to remain meaningful in the presence of the
5857 default hash implementation (object.__hash__), it is now possible
5858 to explicit block inheritance of hash by setting __hash__=None at
5859 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5860 level.
5861
Nick Coghlanb028f502008-07-13 14:52:36 +00005862- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5863 the parent module cannot be found while performing an absolute import.
5864 This means that an incorrectly defined __package__ attribute will
5865 now only prevent relative imports in that module rather than causing
5866 all imports from that module to fail.
5867
Nick Coghlan14ff9942008-07-08 14:21:42 +00005868- Issue #2517: Allow unicode messages in Exceptions again by correctly
5869 bypassing the instance dictionary when looking up __unicode__ on
5870 new-style classes.
5871
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005872- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5873 set to a custom object whose write() method happens to install
5874 another file in sys.stdout.
5875
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005876- Issue #3088: Corrected a race condition in classes derived from
5877 threading.local: the first member set by a thread could be saved in
5878 another thread's dictionary.
5879
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005880- Issue #3004: Minor change to slice.indices(): the start and stop
5881 arguments are now treated identically, making the behaviour easier
5882 to describe and understand. For example, slice(None, -10,
5883 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5884 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5885 10, -1).
5886
Georg Brandl278fc502008-07-19 12:46:12 +00005887- Issue #3219: Calling a function with repeated keyword arguments,
5888 f(a=2, a=23), would not cause a syntax error. This was a regression
5889 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005890
Georg Brandl278fc502008-07-19 12:46:12 +00005891- Issue #2862: Make int and float freelist management consistent with
5892 other freelists. Changes their CompactFreeList apis into
5893 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005894

5897
Thomas Heller57adf222008-08-14 19:10:48 +00005898- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5899 api functions without holding the GIL, which could lead to a fatal
5900 error when they failed.
5901
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005902- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005910- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5911 ForkingPickler.register() to resolve conflict with ctypes.
5912
Vinay Sajip51e65192008-07-18 09:01:10 +00005913- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00005915- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5916 a valid dlerror() message.
5917
Thomas Heller2bad6572008-07-15 17:19:50 +00005918- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5919 incomplete structure was created.
5920

5924
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005925- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005926
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005927- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5928 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005929 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005930 content-length. The problem had been corrected in the 2.4 branch, but never
5931 merged into trunk.
5932
Georg Brandle78fbcc2008-07-05 10:13:36 +00005933- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005944 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005945
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005946- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5947 handling is now the same as that of other special attributes like __name__).
5948
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005949- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5950 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00006339 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006340
6341 This is controlled by the configure argument ``--with-universal-archs``:
6342
6343 - ``--with-universal-archs=all``: install 4-way universal
6344
6345 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6346
6347 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6348
6349 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006401- Issue #1631171: Re-implement the 'warnings' module in C (the
6402 original Python code has been kept as backup). This will allow for
6403 using the 'warning's machinery in such places as the parser where
6404 use of pure Python code is not possible. Both the ``showarning()``
6405 and ``formatwarning()`` gain an optional 'line' argument which is
6406 not called by default for backwards-compatibility reasons. Setting
6407 ``warnings.showwarning()`` to an implementation that lacks support
6408 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006471- Issue #2550: The approach used by client/server code for obtaining
6472 ports to listen on in network-oriented tests has been refined in an
6473 effort to facilitate running multiple instances of the entire
6474 regression test suite in parallel without issue.
6475 test_support.bind_port() has been fixed such that it will always
6476 return a unique port -- which wasn't always the case with the
6477 previous implementation, especially if socket options had been set
6478 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6479 new implementation of bind_port() will actually raise an exception
6480 if it is passed an AF_INET/SOCK_STREAM socket with either the
6481 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6482 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6483 the socket it's been passed. This currently only applies to
6484 Windows. This option prevents any other sockets from binding to the
6485 host/port we've bound to, thus removing the possibility of the
6486 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6487 when a second SOCK_STREAM socket binds and accepts to a host/port
6488 that's already been bound by another socket. The optional preferred
6489 port parameter to bind_port() has been removed. Under no
6490 circumstances should tests be hard coding ports!
6491
6492 test_support.find_unused_port() has also been introduced, which will
6493 pass a temporary socket object to bind_port() in order to obtain an
6494 unused port. The temporary socket object is then closed and
6495 deleted, and the port is returned. This method should only be used
6496 for obtaining an unused port in order to pass to an external program
6497 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6498 a parameter to a server-oriented class that doesn't give you direct
6499 access to the underlying socket used.
6500
6501 Finally, test_support.HOST has been introduced, which should be used
6502 for the host argument of any relevant socket calls (i.e. bind and
6503 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006504
6505 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006506 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

6508 test_asynchat and test_socket_ssl.
6509
Georg Brandl3ee81df2008-05-17 18:14:43 +00006510 It is now possible for multiple instances of the regression test
6511 suite to run in parallel without issue.

6778-----------------
6779
Fred Drakea8ee94b2008-03-01 02:45:07 +00006780- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006781 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006782
Georg Brandlad61bc82008-02-23 15:11:18 +00006783- Issue #2067: file.__exit__() now calls subclasses' close() method.
6784
6785- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006786
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006787- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006788 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006789
Eric Smitha73fbe72008-02-23 03:09:44 +00006790- Added the future_builtins module, which contains hex() and oct().
6791 These are the PEP 3127 version of these functions, designed to be
6792 compatible with the hex() and oct() builtins from Python 3.0. They
6793 differ slightly in their output formats from the existing, unchanged
6794 Python 2.6 builtins. The expected usage of the future_builtins
6795 module is:
6796 from future_builtins import hex, oct
6797
Eric Smith7ef40bf2008-02-20 23:34:22 +00006798- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6799 exponents for exponents with absolute value < 100. Follows C99
6800 standard. This is a change on Windows, which would use 3 digits.
6801 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6802 so that any alterations it does to the resulting string will be
6803 available in stringlib/formatter.h (for float.__format__).
6804
Eric Smith5a3c1352008-02-19 13:21:56 +00006805- Implemented PEP 3101, Advanced String Formatting. This adds a new
6806 builtin format(); a format() method for str and unicode; a
6807 __format__() method to object, str, unicode, int, long, float, and
6808 datetime; the class string.Formatter; and the C API
6809 PyObject_Format().
6810
Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Fixed several potential crashes, all caused by specially crafted
6812 __del__ methods exploiting objects in temporarily inconsistent
6813 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006814
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006815- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006816 prevent a possible crash: an Abstract Base Class would try to access
6817 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006818
Georg Brandl3ee81df2008-05-17 18:14:43 +00006819- Fixed repr() and str() of complex numbers with infinity or nan as
6820 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006821
Georg Brandl3ee81df2008-05-17 18:14:43 +00006822- Clear all free lists during a gc.collect() of the highest generation
6823 in order to allow pymalloc to free more arenas. Python may give back
6824 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006825
Georg Brandl3ee81df2008-05-17 18:14:43 +00006826- Issue #2045: Fix an infinite recursion triggered when printing a
6827 subclass of collections.defaultdict, if its default_factory is set
6828 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006829
Christian Heimesf75dbef2008-02-08 00:11:31 +00006830- Fixed a minor memory leak in dictobject.c. The content of the free
6831 list was not freed on interpreter shutdown.
6832
Georg Brandl21e99f42010-03-07 15:23:59 +00006833- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006834 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006835
Georg Brandl3ee81df2008-05-17 18:14:43 +00006836- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6837 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006838 to compact the internal free lists of pre-allocted ints and floats.
6839
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6841 calls. Python expected the return type int but the fork familie
6842 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006843
Georg Brandl3ee81df2008-05-17 18:14:43 +00006844- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6845 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006846
Georg Brandl3ee81df2008-05-17 18:14:43 +00006847- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6848 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006849
Georg Brandl3ee81df2008-05-17 18:14:43 +00006850- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6851 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006852
Georg Brandl3ee81df2008-05-17 18:14:43 +00006853- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6854 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006855
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856- Patch #1473257: generator objects gain a gi_code attribute. This is
6857 the same object as the func_code attribute of the function that
6858 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006859
Georg Brandl3ee81df2008-05-17 18:14:43 +00006860- Issue #1920: "while 0" statements were completely removed by the
6861 compiler, even in the presence of an "else" clause, which is
6862 supposed to be run when the condition is false. Now the compiler
6863 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006864
Guido van Rossumeead05f2008-01-24 18:21:02 +00006865- A few crashers fixed: weakref_in_del.py (issue #1377858);
6866 loosing_dict_ref.py (issue #1303614, test67.py);
6867 borrowed_ref_[34].py (not in tracker).
6868
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006869- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006870 suppressed while an extension is loaded by calling SetErrorMode in
6871 dynload_win.c. The error is still reported properly.
6872
Georg Brandl3ee81df2008-05-17 18:14:43 +00006873- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006874 several extension methods and modules do not work without unicode
6875 support.
6876
Georg Brandl26543b12008-01-21 18:36:51 +00006877- Issue #1882: when compiling code from a string, encoding cookies in the
6878 second line of code were not always recognized correctly.
6879
Georg Brandl14404b62008-01-19 19:27:05 +00006880- Issue #1679: "0x" was taken as a valid integer literal.
6881
Georg Brandl6caad7d2008-01-26 14:19:22 +00006882- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006883 added.
6884
Christian Heimesc94e2b52008-01-14 04:13:37 +00006885- sys.float_info / PyFloat_GetInfo: The floating point information
6886 object was converted from a dict to a specialized structseq object.
6887
Georg Brandl3ee81df2008-05-17 18:14:43 +00006888- Patch #1816: Added sys.flags structseq. It exposes the status of
6889 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006890
Georg Brandl3ee81df2008-05-17 18:14:43 +00006891- Objects/structseq.c: Implemented new structseq representation. The
6892 patch makes structseqs (e.g. the return value of os.stat) more
6893 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006894
Georg Brandl3ee81df2008-05-17 18:14:43 +00006895- Patch #1700288: added a type attribute cache that caches method
6896 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006897
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006898- Bug #1776: __import__() no longer accepts filenames on any platform.
6899 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006900
Georg Brandlaed6c662008-01-07 17:25:53 +00006901- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6902
Georg Brandl3ee81df2008-05-17 18:14:43 +00006903- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6904 envvar and sys.dont_write_bytecode attribute. All these can be set
6905 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006906
Georg Brandl3ee81df2008-05-17 18:14:43 +00006907- Improve some exception messages when Windows fails to load an
6908 extension module. Now we get for example '%1 is not a valid Win32
6909 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006910
Georg Brandl3ee81df2008-05-17 18:14:43 +00006911- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6914 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006915
Christian Heimes0a8143f2007-12-18 23:22:54 +00006916- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006917 and INF. float("nan"), float("inf") and float("-inf") now work on
6918 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006919
Georg Brandl3ee81df2008-05-17 18:14:43 +00006920- Compiler now generates simpler and faster code for dictionary
6921 literals. The oparg for BUILD_MAP now indicates an estimated
6922 dictionary size. There is a new opcode, STORE_MAP, for adding
6923 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006924
Georg Brandl3ee81df2008-05-17 18:14:43 +00006925- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006930- Issue #1538: Avoid copying string in split/rsplit if the split char
6931 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006932
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006933- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006934 SystemError.
6935
Nick Coghlanef01d822007-12-03 12:55:17 +00006936- PEP 366: Allow explicit relative imports when executing modules
6937 inside packages with the -m switch via a new module level
6938 __package__ attribute.
6939
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940- Issue #1402: Fix a crash on exit, when another thread is still
6941 running, and if the deallocation of its frames somehow calls the
6942 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006943

6953 file can now be directly executed by passing their name to the
6954 interpreter. The directory/zipfile is automatically inserted as the
6955 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006956
Georg Brandl3ee81df2008-05-17 18:14:43 +00006957- Issue #1265: Fix a problem with sys.settrace, if the tracing
6958 function uses a generator expression when at the same time the
6959 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006960
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006961- sets and frozensets now have an isdisjoint() method.
6962
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006963- optimize the performance of builtin.sum().
6964
Neal Norwitz44f326e2007-10-05 05:29:17 +00006965- Fix warnings found by the new version of the Coverity checker.
6966
Georg Brandl21e99f42010-03-07 15:23:59 +00006967- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006968 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6969 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006970
Georg Brandl3ee81df2008-05-17 18:14:43 +00006971- Issue #1686386: Tuple's tp_repr did not take into account the
6972 possibility of having a self-referential tuple, which is possible
6973 from C code. Nor did object's tp_str consider that a type's tp_str
6974 could do something that could lead to an inifinite recursion.
6975 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6976 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006977
Georg Brandl3ee81df2008-05-17 18:14:43 +00006978- Issue #1164: It was possible to trigger deadlock when using the
6979 'print' statement to write to a file since the GIL was not released
6980 as needed. Now PyObject_Print() does the right thing along with
6981 various tp_print implementations of the built-in types and those in
6982 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006983
Georg Brandl3ee81df2008-05-17 18:14:43 +00006984- Issue #1147: Exceptions were directly allowing string exceptions in
6985 their throw() method even though string exceptions no longer
6986 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006987
Georg Brandl3ee81df2008-05-17 18:14:43 +00006988- Issue #1096: Prevent a segfault from getting the repr of a very
6989 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00006991- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006992 PyObject_Call() never calling back out to Python code to trigger
6993 recursion depth updates/checks. Required the creation of a static
6994 RuntimeError instance in case normalizing an exception put the
6995 recursion check value past its limit. Fixes crashers
6996 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006997
Georg Brandl3ee81df2008-05-17 18:14:43 +00006998- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007011- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007012 __*__ attributes. (Some already existed, e.g., __doc__ and
7013 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007014
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007015- Add -3 option to the interpreter to warn about features that are

7020
Collin Winter62903052007-05-18 23:11:24 +00007021- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007022 "except E as target:". This is to provide forwards compatibility
7023 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007024
Brett Cannon229cee22007-05-05 01:34:02 +00007025- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007027- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007028 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007030- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007031 setting a plain string, ie don't expand to single letter identifiers.
7032
Raymond Hettinger13936692007-04-11 18:40:58 +00007033- Request #1191699: Slices can now be pickled.

7043
Guido van Rossum143b5642007-03-23 04:58:42 +00007044- Bug #1683368: The object.__init__() and object.__new__() methods are
7045 now stricter in rejecting excess arguments. The only time when
7046 either allows excess arguments is when it is not overridden and the
7047 other one is. For backwards compatibility, when both are
7048 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007049 warning later). Also, type.__init__() insists on the same signature
7050 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007051
Georg Brandl3ee81df2008-05-17 18:14:43 +00007052- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7053 object to complex using its __complex__() method before falling back
7054 to the __float__() method. Therefore, the functions in the cmath
7055 module now can operate on objects that define a __complex__()
7056 method.

7073
Georg Brandl7b9c5552007-03-12 14:30:05 +00007074- Bug #1678647: write a newline after printing an exception in any
7075 case, even when converting the value to a string failed.
7076
Georg Brandl871f1bc2007-03-12 13:17:36 +00007077- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007078 its argument, if it exists. If not, it will work like before. This
7079 allows customizing the output of dir() in the presence of a
7080 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007081
Collin Winter276887b2007-03-12 16:11:39 +00007082- Patch #922167: Python no longer segfaults when faced with infinitely
7083 self-recursive reload() calls (as reported by bug #742342).

7089 parthensized forms. This means complex(repr(x)) now works instead of
7090 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007091
Georg Brandlaa2321b2007-03-07 00:40:28 +00007092- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007093 makes the filenames the warning module prints much more sensible
7094 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007095

Georg Brandl0fca97a2007-03-05 22:28:08 +00007107- Patch #1674228: when assigning a slice (old-style), check for the
7108 sq_ass_slice instead of the sq_slice slot.
7109
Georg Brandl3ee81df2008-05-17 18:14:43 +00007110- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00007645 AttributeError instead of an IOError when the server's response
7646 didn't contain a valid HTTP status line.

Georg Brandl92a6bae2007-03-13 17:43:32 +00007679- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007680 are set for invalid interpolation sequences that would lead to
7681 errors on reading back those values.

7737 TestCase and TestSuite subclasses (not instances) are no longer
7738 accepted in TestSuite.addTest(). This should cause no

7740 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8023 with RFC 3207 and forgets any knowledge obtained from the server not
8024 obtained from the TLS negotiation itself. Patch contributed by Bill
8025 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008026
Georg Brandl3ee81df2008-05-17 18:14:43 +00008027- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008028 that the SMTP.starttls() caller no longer needs to call ehlo()
8029 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008030 does not claim to support starttls. Adds the
8031 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8112 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8113 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00008130 time so that opening a database previously created with the DB_DUP
8131 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8132 opens. Specifically: dictionary assignment to a DB object will
8133 replace all values for a given key when the database allows
8134 duplicate values. DB users should use DB.put(k, v) when they want
8135 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008136

8142 characters with ASCII value less than 32. Also, it correctly quotes
8143 dots only if they occur on a single line, as opposed to the previous
8144 behavior of quoting dots if they are the second character of any
8145 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008475- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8476 to ``PyTuple_SetItem``, it can be used to populate a brand new
8477 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008478
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008479- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008481- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8482 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8483 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008484
8485- Patch #1720595: add T_BOOL to the range of structmember types.
8486
8487- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8488 ``PyFloat_GetInfo()`` to the float API.
8489
Georg Brandl3ee81df2008-05-17 18:14:43 +00008490- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8491 of w# format code incorrectly truncated the length to an int, even
8492 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8493 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008494
Georg Brandl3ee81df2008-05-17 18:14:43 +00008495- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8496 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008497
Georg Brandl3ee81df2008-05-17 18:14:43 +00008498- PEP 3123: Provide forward compatibility with Python 3.0, while
8499 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8500 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008501
Georg Brandl3ee81df2008-05-17 18:14:43 +00008502- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8503 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008504
8505- Patch #1733960: Allow T_LONGLONG to accept ints.
8506
8507- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8508
Christian Heimes000a0742008-01-03 22:16:32 +00008509- Added a new API function ``PyImport_ImportModuleNoBlock``.
8510
Georg Brandl6caad7d2008-01-26 14:19:22 +00008511- Bug #1637022: Prefix AST symbols with _Py_.
8512
8513- Fix some leftovers from the conversion from int to Py_ssize_t
8514 (relevant to strings and sequences of more than 2**31 items).
8515
8516- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8517 outside of pystate.c and should not be necessary.
8518
Georg Brandl3ee81df2008-05-17 18:14:43 +00008519- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8520 absolute imports. In earlier versions they might have used relative
8521 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008522
Georg Brandl3ee81df2008-05-17 18:14:43 +00008523- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8524 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008525
Georg Brandl3ee81df2008-05-17 18:14:43 +00008526- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8527 macro so it can be used as an expression.

8532
Georg Brandl3ee81df2008-05-17 18:14:43 +00008533- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8534 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8535 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8536 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008537
Georg Brandl3ee81df2008-05-17 18:14:43 +00008538- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
8539 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00008549- buildtools now raises a DeprecationWarning.
8550
Georg Brandl3ee81df2008-05-17 18:14:43 +00008551- Removed the macfs module. It had been deprecated since Python 2.5.
8552 This lead to the deprecation of macostools.touched() as it relied
8553 solely on macfs and was a no-op under OS X.
