13 Python 3.1. callable() is again supported in Python 3.2.
14
Victor Stinner59729ff2011-07-05 11:28:19 +020015- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
16 os.write() clamp the length to INT_MAX on Windows.
17
Victor Stinnerd3c7e172011-05-30 23:49:13 +020018- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020019 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
20 raw_input() interrupted by CTRL+c.

34 the garbage collector while the Heap lock is held.
35
Ned Deily87e82bb2011-06-28 19:52:59 -070036- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
37 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
38 interpreter process. This could cause failures in non-Distutils subprocesses
39 and was unreliable since tests or user programs could modify the interpreter
40 environment after Distutils set it. Instead, have Distutils set the the
41 deployment target only in the environment of each build subprocess. It is
42 still possible to globally override the default by setting
43 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
44 greater or equal to the default value, the value with which the interpreter
45 was built.
46
Raymond Hettinger2c316a32011-06-25 17:14:53 +020047- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

R David Murrayf1138bb2011-06-17 22:23:04 -040053- Issue #11700: mailbox proxy object close methods can now be called multiple
54 times without error, and _ProxyFile now closes the wrapped file.
55
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020056- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
57 connection if its getresponse() method fails with a socket error. Patch
58 written by Ezio Melotti.
59
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -050060- Issue #9284: Allow inspect.findsource() to find the source of doctest
61 functions.

72
Raymond Hettinger19b851d2011-06-01 18:21:42 -070073- sys.setcheckinterval() now updates the current ticker count as well as updating
74 the check interval, so if the user decreases the check interval, the ticker
75 doesn't have to wind down to zero from the old starting point before the new
76 interval takes effect. And if the user increases the interval, it makes sure
77 the new limit takes effect right away rather have an early task switch before
78 recognizing the new interval.
79
Victor Stinner776e69b2011-06-01 01:03:00 +020080- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
81 constructor has failed, e.g. because of an undeclared keyword argument. Patch

Raymond Hettinger20397532010-09-12 02:11:45 +0000911- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
912 This prevents user-created self-referencing ordered dictionaries from
913 becoming permanently uncollectable GC garbage. The downside is that
914 removing __del__ means that the internal doubly-linked list has to wait for
915 GC collection rather than freeing memory immediately when the refcnt drops
916 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001375- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1376 start byte and the continuation byte(s) are now considered invalid, instead
1377 of the number of bytes specified by the start byte.
1378 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1379 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1380 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1390 objects. (1) The comparison could incorrectly return True in some cases
1391 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1392 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001736 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1737 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1738 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1758Core and Builtins
1759-----------------
1760
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001761- Issue #7301: Add environment variable $PYTHONWARNINGS.
1762
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001763- Issue #8329: Don't return the same lists from select.select when no fds are
1764 changed.
1765
Georg Brandlfee0f442010-05-22 21:26:21 +00001766- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001767 on 64-bit machines. The shift count for either left or right shift is
1768 permitted to be up to sys.maxsize.
1769
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001770- Ensure that tokenization of identifiers is not affected by locale.
1771
Georg Brandlfee0f442010-05-22 21:26:21 +00001772- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001773
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001774- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1775
Georg Brandlfee0f442010-05-22 21:26:21 +00001776- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1777 with a non-empty format string. This is an effort to future-proof user
1778 code. If a derived class does not currently implement __format__ but later
1779 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001780 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001781 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001782
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001783- Issue #8268: Old-style classes (not just instances) now support weak

1792 arguments to a function correct.
1793
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001794- Issue #8164: Don't allow lambda functions to have a docstring.
1795
Victor Stinner66644262010-03-10 22:30:19 +00001796- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001797 (SIGINT). If an error occurs while importing the site module, the error is
1798 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001799 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00001812- Issue #8310: Allow dis to examine new style classes.
1813
Georg Brandlfee0f442010-05-22 21:26:21 +00001814- Issue #8257: The Decimal construct now accepts a float instance directly,
1815 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001816
1817 >>> Decimal(1.1)
1818 Decimal('1.100000000000000088817841970012523233890533447265625')
1819
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001820- collections.Counter() now supports a subtract() method.
1821
Georg Brandlfee0f442010-05-22 21:26:21 +00001822- The functools module now has a total_ordering() class decorator to simplify
1823 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001824
Georg Brandlfee0f442010-05-22 21:26:21 +00001825- The functools module also adds cmp_to_key() as a tool to transition old-style
1826 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001827
Georg Brandlfee0f442010-05-22 21:26:21 +00001828- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1829 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001830
Georg Brandlfee0f442010-05-22 21:26:21 +00001831- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1832 InvalidOperation instead of returning False. (Comparisons involving a quiet
1833 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1834 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001835
Georg Brandlfee0f442010-05-22 21:26:21 +00001836- Issue #2531: Comparison operations between floats and Decimal instances now
1837 return a result based on the numeric values of the operands; previously they
1838 returned an arbitrary result based on the relative ordering of id(float) and
1839 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001840
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001841- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001842 argument `-` which tells it to read files to compile from stdin. Each line is
1843 read on demand and the named file is compiled immediately. (Original patch by
1844 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001845
Georg Brandlfee0f442010-05-22 21:26:21 +00001846- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
1847 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00001849- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1850 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001851 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001852
Georg Brandlfee0f442010-05-22 21:26:21 +00001853- Comparisons using one of <, <=, >, >= between a complex instance and a
1854 Fractions instance now raise TypeError instead of returning True/False. This
1855 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1856 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001857

1866
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001867- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001868 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1869 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001870
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001871- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1872 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00001912 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1913 log file to compute the next rollover time. If the log file does not exist,

1961 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1962 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001963 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1964 inconsistent: __int__ was used for some integer codes but not for others, and
1965 the set of integer codes for which it was used differed between native packing
1966 and standard packing.)

2198 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002199 library would return a bogus result; on Solaris, it was possible to crash the
2200 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00002213- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2214 and add the additional members returned in an OSVERSIONINFOEX structure. The
2215 new members are service_pack_major, service_pack_minor, suite_mask, and
2216 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00002218- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2219 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2220 returning NULL. The macro now returns a statically allocated empty string
2221 instead.

2231 strings,
2232 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2233 numeric strings corresponding to subnormal values,
2234 (3) a memory leak for some values large enough to cause overflow, and
2235 (4) a number of flaws that could lead to incorrectly rounded results.

2253 interpreter shutdown.
2254
Georg Brandlba83f822010-03-14 09:50:54 +00002255- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

2257 by the XML specification, and are necessary when outputting e.g. PHP code in
2258 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00002266- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002267 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002268 Also, raise ValueError rather than TypeError when an unknown TIPC address
2269 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002273- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002274 file position when calling `truncate()`. It would previously change the file
2275 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002276 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2277
Georg Brandlba83f822010-03-14 09:50:54 +00002278- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2279 class used to represent files stored inside an archive. The new
2280 implementation is significantly faster and can be wrapped in a
2281 ``io.BufferedReader`` object for more speedups. It also solves an issue
2282 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2283 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00002284
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00002285- Issue #7792: Registering non-classes to ABCs raised an obscure error.

2291 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00002292
Georg Brandlba83f822010-03-14 09:50:54 +00002293- Issue #7748: Since unicode values are supported for some metadata options in
2294 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2295 encoded string for them. This ensures that the upload and register commands
2296 send the correct values to PyPI without any error.

2408
Georg Brandlba83f822010-03-14 09:50:54 +00002409 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002434 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2435 alternative to cPickle if you care about performance. Patch by Florent

2550 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2551 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002552
Georg Brandlba83f822010-03-14 09:50:54 +00002553- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2554 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002555
Georg Brandlba83f822010-03-14 09:50:54 +00002556- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2557 1e-100 used to raise OverflowError, but now gives the requested 120
2558 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002567- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2568 decimal string that's guaranteed to round back to x under correct rounding
2569 (with round-half-to-even rounding mode). Previously it gave a string based on
2570 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2571 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2572 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002573
Georg Brandlba83f822010-03-14 09:50:54 +00002574- Issue #7117: On almost all platforms: float-to-string and string-to-float
2575 conversions within Python are now correctly rounded. Places these conversions
2576 occur include: str for floats and complex numbers; the float and complex
2577 constructors; old-style and new-style numeric formatting; serialization and
2578 deserialization of floats and complex numbers using marshal, pickle and json;
2579 parsing of float and imaginary literals in Python code; Decimal-to-float
2580 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002581
Georg Brandlba83f822010-03-14 09:50:54 +00002582 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2583 providing correctly-rounded strtod and dtoa C functions. This code is
2584 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2585 the C compiler. There may be a small number of platforms on which correct
2586 operation of this code cannot be guaranteed, so the code is not used: notably,
2587 this applies to platforms where the C double format is not IEEE 754 binary64,
2588 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2589 and Python's configure script is unable to determine how to change the FPU
2590 precision. On these platforms conversions use the platform strtod and dtoa,
2591 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002592
Georg Brandlba83f822010-03-14 09:50:54 +00002593- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2594 uses the correctly-rounded string <-> float conversions described above (when
2595 available), and so produces correctly rounded results that will display nicely
2596 under the float repr. There are two related small changes: (1) round now
2597 accepts any class with an ``__index__()`` method for its second argument (but
2598 no longer accepts floats for the second argument), and (2) an excessively
2599 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2600 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002604- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00002747- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2748 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2749 but with at least one decimal point and with a default precision
2750 of 12. Previously, the behavior the same but with a default precision of 6.
2751 This more closely matches ``str()``, and reduces surprises when adding
2752 alignment flags to the empty presentation type. This also affects the new
2753 complex.__format__ in the same way.

2892
Georg Brandlba83f822010-03-14 09:50:54 +00002893- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2894 existing .py counterpart, override the co_filename attributes of all code
2895 objects if the original filename is obsolete (which can happen if the file has
2896 been renamed, moved, or if it is accessed through different paths). Patch by
2897 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00002898
Georg Brandlba83f822010-03-14 09:50:54 +00002899- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.
Martin v. Löwis5344c992009-01-02 20:32:55 +00002900
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00002901- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
2902 file with `str' filename on Windows.
2903
Antoine Pitrouaa687902009-01-01 14:11:22 +00002904- Issue #3680: Reference cycles created through a dict, set or deque iterator
2905 did not get collected.
2906
Georg Brandlba83f822010-03-14 09:50:54 +00002907- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
2908 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00002909
Benjamin Peterson7af65562008-12-29 17:56:58 +00002910- Issue #4764: With io.open, IOError.filename is set when trying to open a
2911 directory on POSIX systems.
2912
Benjamin Petersonfe231b02008-12-29 17:47:42 +00002913- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
2914 systems.
2915
Georg Brandl6425a2f2008-12-28 11:54:53 +00002916- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002917 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002918
Skip Montanarof205c132008-12-23 03:30:15 +00002919- Added test case to ensure attempts to read from a file opened for writing
2920 fail.
2921
Georg Brandlba83f822010-03-14 09:50:54 +00002922- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2923 elapsed times, not only when some objects are uncollectable/unreachable.
2924 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00002925
Mark Dickinson1a707982008-12-17 16:14:37 +00002926- Issue #3439: Add a bit_length method to int and long.
2927
Georg Brandlba83f822010-03-14 09:50:54 +00002928- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
2929 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00002930
Georg Brandlba83f822010-03-14 09:50:54 +00002931- Issue #4597: Fixed exception handling when the __exit__ function of a context
2932 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00002933
Georg Brandlba83f822010-03-14 09:50:54 +00002934- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00002935
Georg Brandlba83f822010-03-14 09:50:54 +00002936- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2937 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2938 instances. On a typical machine this saves 3 bytes of memory (on average) per
2939 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002940
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002941- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2942 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2943 instead of throwing a MemoryError.
2944
Georg Brandlba83f822010-03-14 09:50:54 +00002945- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2946 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002947
Benjamin Petersonc078f922008-11-21 22:27:24 +00002948- Issue #4367: Python would segfault during compiling when the unicodedata
2949 module couldn't be imported and \N escapes were present.
2950
Georg Brandlba83f822010-03-14 09:50:54 +00002951- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2952 file objects with closefd=False. The file descriptor is still kept open but
2953 the file object behaves like a closed file. The ``FileIO`` object also got a
2954 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002955
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002956- Issue #4348: Some bytearray methods returned that didn't cause any change to
2957 the bytearray, returned the same bytearray instead of a copy.
2958
Georg Brandlba83f822010-03-14 09:50:54 +00002959- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00002961- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
2962
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002963- Issue #4048: The parser module now correctly validates relative imports.
2964
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002965- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
2966 exec statement.
2967
Georg Brandlba83f822010-03-14 09:50:54 +00002968- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
2969 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00002970
Benjamin Petersonbdca9422008-10-26 20:21:13 +00002971- Issue #4209: Enabling unicode_literals and the print_function in the same
2972 __future__ import didn't work.
2973
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002974- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002975 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002976
Georg Brandlba83f822010-03-14 09:50:54 +00002977- On windows, ``os.chdir()`` given unicode was not working if
2978 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2979 this code path is really executed because I cannot move to such directory on
2980 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002981
Georg Brandlba83f822010-03-14 09:50:54 +00002982- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2983 element is temporarily replaced with an equivalent frozenset. But the
2984 eventual KeyError would always report the empty ``frozenset()`` as the missing
2985 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00002986
Georg Brandlba83f822010-03-14 09:50:54 +00002987- Issue #4509: Various issues surrounding resize of bytearray objects to which
2988 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00002989
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00002990- Issue #4748: Lambda generators no longer return a value.
2991

2993
Gregory P. Smithae91d092009-03-02 05:13:57 +00002994- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
2995
Georg Brandlba83f822010-03-14 09:50:54 +00002996- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
2997 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00002998
Matthias Klose91a3b9e2009-04-05 21:19:13 +00002999- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3000 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003001
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003002- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3003 returned them on 64bit platforms.
3004
Walter Dörwalded960ac2009-05-03 22:36:33 +00003005- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3006 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3007 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3008 of using the replace error handler in PyUnicode_DecodeUTF8().
3009
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003010- Issue #3739: The unicode-internal encoder now reports the number of characters
3011 consumed like any other encoder (instead of the number of bytes).
3012
Georg Brandlba83f822010-03-14 09:50:54 +00003013- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3014 allocator will be automatically disabled when running under Valgrind. This
3015 gives improved memory leak detection when running under Valgrind, while taking
3016 advantage of pymalloc at other times.

3043 from the user's group and inherit from its container when the test is run.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004258- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4259 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004260 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4261 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00004263- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4264 regression tests in parallel, shortening the total runtime.
4265
Georg Brandlba83f822010-03-14 09:50:54 +00004266- Issue #5354: New test support function import_fresh_module() makes it easy to
4267 import both normal and optimised versions of modules. test_heapq and
4268 test_warnings have been adjusted to use it, tests for other modules with both
4269 C and Python implementations in the stdlib can be adjusted to use it over
4270 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004278- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4279 should cause a test to be skipped are now done using import_module from test
4280 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004381- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4382
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004383- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4384 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4385 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4386 ``printf`` function, whereas PyString_FromFormat has an independent
4387 implementation and uses "%zd" on all platforms for size_t values.
4388 This makes a difference on win64, where ``printf`` needs "%Id" to display
4389 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004391- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4395 object; previously an int would be returned for small values. the __long__
4396 method is allowed to return either an int or a long, but the behaviour of
4397 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004399- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004406 was correctly parsed but parsing of subsequent arguments failed.
4407
Vinay Sajip35e3b032008-09-01 14:33:59 +00004408- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004409 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4410 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4411 when given a tuple of classes as second argument, were looking up
4412 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4413 type object.
4414
Neal Norwitz18aa3882008-08-24 05:04:52 +00004415- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004552What's New in Python 2.6 beta 3?
4553================================
4554
Barry Warsaw07a4a382008-08-21 01:15:08 +00004555*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004556
4557Core and Builtins
4558-----------------
4559
Guido van Rossumf8402962008-08-20 15:01:50 +00004560- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4561 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4562 extensions do not automatically benefit from the class attribute
4563 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4564 to their tp_flags field if they care. This is a backwards
4565 compatibility feature; in 3.0, all types will use the cache by
4566 default.
4567
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004568- Keyword arguments can now follow starred arguments. (``f(a, *args,
4569 keyword=23)`` is now valid syntax.)
4570
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004571- ctypes function pointers that are COM methods have a boolean True
4572 value again.
4573
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004574- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4575 by denying s# to parse objects that have a releasebuffer procedure,
4576 and introducing s*.
4577
Georg Brandl1e13ea92008-08-11 09:07:59 +00004578- Issue #3537: Fix an assertion failure when an empty but presized dict
4579 object was stored in the freelist.
4580
Mark Dickinsonb6467572008-08-04 21:30:09 +00004581- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4582 ValueError consistently across platforms.
4583
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004584- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4585 (64bit Unix, for example), unichr() would truncate its argument and return
4586 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4587
Neal Norwitze7d8be82008-07-31 17:17:14 +00004588- Apply security patches from Apple.
4589
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004590- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4591 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4592
Antoine Pitrou92f82162008-07-25 22:22:08 +00004593- Issue #1819: function calls with several named parameters are now on
4594 average 35% faster (as measured by pybench).
4595
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004596- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4597 the python debugger steps into a class statement: the free variables (local
4598 variables defined in an outer scope) would be deleted from the outer scope.
4599
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004600- Issue #2620: Overflow checking when allocating or reallocating memory
4601 was not always being done properly in some python types and extension
4602 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4603 all been updated to perform better checks and places in the code that
4604 would previously leak memory on the error path when such an allocation
4605 failed have been fixed.
4606
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004607Library
4608-------
4609
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004610- Issue #3612: Added some missing basic types in ctypes.wintypes.
4611
Benjamin Petersone977ad42008-08-20 01:42:01 +00004612- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4613 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4614
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004615- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4616 version reported by these tools does not necessarily follow the python
4617 version numbering scheme, so the module is less strict when parsing it.
4618
Nick Coghlanf70385a2008-08-18 12:42:46 +00004619- Issue #2235: Added Py3k warnings for types which will become unhashable
4620 under the stricter __hash__ inheritance rules in 3.0. Several types
4621 which did not meet the rules for hash invariants and were already
4622 unhashable in 3.0 have now been explicitly flagged as unhashable in
4623 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4624 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4625
Brett Cannon88f801d2008-08-18 00:46:22 +00004626- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4627 imported into the module but exposed as part of the module's API.
4628
Brett Cannon7b96f072008-08-18 00:41:11 +00004629- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4630
Brett Cannon46225e72008-08-18 00:36:52 +00004631- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4632
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004633- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4634
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004635- Issue #3575: Incremental decoder's decode function now takes bytearray
4636 by using 's*' instead of 't#'.
4637
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004638- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004639 fails unicode conversion on 2nd parameter. (windows only)
4640
Georg Brandl222e2082010-08-01 22:27:39 +00004641- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004642 in a redirect.
4643
Brett Cannonabe423e2008-08-16 21:47:07 +00004644- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004645 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004646
Facundo Batistaeb90b782008-08-16 14:44:07 +00004647- Issue #2776: fixed small issue when handling an URL with double slash
4648 after a 302 response in the case of not going through a proxy.
4649
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004650- Issue #2676: in the email package, content-type parsing was hanging on
4651 pathological input because of quadratic or exponential behaviour of a
4652 regular expression.
4653
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004654- Issue #3476: binary buffered reading through the new "io" library is now
4655 thread-safe.
4656
Brett Cannonbf3157b2008-08-14 05:00:03 +00004657- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4658 since mimetools itself is deprecated. Because modules are cached, all
4659 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4660
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004661- Issue #3134: shutil referenced undefined WindowsError symbol.
4662
Robert Schuppenies14646332008-08-10 11:01:53 +00004663- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4664 menu entries were not deleted.
4665
Brett Cannon83e81842008-08-09 23:30:55 +00004666- Copied the implementation of reduce() to _functools.reduce() to have a
4667 version that did not raise a DeprecationWarning under -3.
4668
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004669- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4670 a MemoryError rather than silently stop the iteration.
4671
Guido van Rossum59ce9012008-08-09 14:55:34 +00004672- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4673 to _sre.compile() will now be rejected. This should not affect anybody
4674 since the re.compile() function never generates invalid re-bytecode.
4675
Skip Montanaroa032bf42008-08-08 22:52:51 +00004676- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4677 upon first access it can be automatically initialized from the csv file if
4678 it wasn't initialized during instantiation.
4679
Brett Cannon3aa2a492008-08-06 22:28:09 +00004680- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4681 the reload() built-in has been removed.
4682
Brett Cannon7e30b672008-08-04 21:52:25 +00004683- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004684 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004685 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4686 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4687 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4688 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4689 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004690
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004691- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4692 raised an AttributeError.
4693
Benjamin Peterson01a24322008-07-28 23:35:27 +00004694- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004695 asking for a specific length. This problem only affected files opened
4696 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004697
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004698- Issue #3449: Update decimal module to use most recent specification
4699 (v. 1.68) and tests (v. 2.58) from IBM.
4700
Georg Brandl222e2082010-08-01 22:27:39 +00004701- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004702
Georg Brandl222e2082010-08-01 22:27:39 +00004703- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00004704 on a closed shelf.
4705
Georg Brandlf9efabb2008-07-23 15:16:45 +00004706- Deprecate the "ast" parser function aliases.
4707
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004708- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4709
4710- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4711 invalid arguments.
4712
4713- Issue #3302: Fix several crashes when calling locale's gettext functions
4714 with None arguments.
4715
4716- Issue #3389: Allow resolving dotted names for handlers in logging
4717 configuration files.
4718
4719- Deprecate the sunaudio module for removal in Python 3.0.
4720
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004721- Issue #3394: zipfile.writestr sets external attributes when passed a
4722 file name rather than a ZipInfo instance, so files are extracted with
4723 mode 0600 rather than 000 under Unix.
4724
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004725- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4726 argument in python 2.5, this broke code that subclassed Popen to include its
4727 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4735-------------
4736
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004737- Issue #2235: the C API function PyObject_HashNotImplemented and its
4738 interaction with the tp_hash slot (added in 2.6b2) are now documented
4739
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004740- Issue #643841: The language reference now provides more detailed
4741 coverage of the lookup process for special methods. The disclaimers
4742 regarding lack of coverage of new-style classes have also been
4743 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004746What's New in Python 2.6 beta 2?
4747================================
4748
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004749*Release date: 17-Jul-2008*
4750
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004751Core and Builtins
4752-----------------
4753
Georg Brandl3e483f62008-07-16 22:57:41 +00004754- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4755 its methods now allow for items objects that can be converted to
4756 an integer using operator.index().
4757
Mark Dickinson64b7e502008-07-16 09:40:03 +00004758- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4759 produced a ValueError instead of giving the correct float.
4760
Eric Smitha5fa5a22008-07-16 00:11:49 +00004761- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4762 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4763
Mark Dickinson7103aa42008-07-15 19:08:33 +00004764- Issue #3008: the float type has a new instance method 'float.hex'
4765 and a new class method 'float.fromhex' to convert floating-point
4766 numbers to and from hexadecimal strings, respectively.
4767
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004768- Issue #2235: __hash__ is once again inherited by default. To allow
4769 collections.Hashable to remain meaningful in the presence of the
4770 default hash implementation (object.__hash__), it is now possible
4771 to explicit block inheritance of hash by setting __hash__=None at
4772 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4773 level.
4774
Nick Coghlanb028f502008-07-13 14:52:36 +00004775- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4776 the parent module cannot be found while performing an absolute import.
4777 This means that an incorrectly defined __package__ attribute will
4778 now only prevent relative imports in that module rather than causing
4779 all imports from that module to fail.
4780
Nick Coghlan14ff9942008-07-08 14:21:42 +00004781- Issue #2517: Allow unicode messages in Exceptions again by correctly
4782 bypassing the instance dictionary when looking up __unicode__ on
4783 new-style classes.
4784
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004785- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4786 set to a custom object whose write() method happens to install
4787 another file in sys.stdout.
4788
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004789- Issue #3088: Corrected a race condition in classes derived from
4790 threading.local: the first member set by a thread could be saved in
4791 another thread's dictionary.
4792
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004793- Issue #3004: Minor change to slice.indices(): the start and stop
4794 arguments are now treated identically, making the behaviour easier
4795 to describe and understand. For example, slice(None, -10,
4796 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4797 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4798 10, -1).
4799
Georg Brandl278fc502008-07-19 12:46:12 +00004800- Issue #3219: Calling a function with repeated keyword arguments,
4801 f(a=2, a=23), would not cause a syntax error. This was a regression
4802 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004803
Georg Brandl278fc502008-07-19 12:46:12 +00004804- Issue #2862: Make int and float freelist management consistent with
4805 other freelists. Changes their CompactFreeList apis into
4806 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004811- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4812 api functions without holding the GIL, which could lead to a fatal
4813 error when they failed.
4814
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004815- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4824 ForkingPickler.register() to resolve conflict with ctypes.
4825
Vinay Sajip51e65192008-07-18 09:01:10 +00004826- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller2bad6572008-07-15 17:19:50 +00004831- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4832 incomplete structure was created.

5249
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005250- On MacOS X it is now possible to install the framework in 64-bit
5251 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005252 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005253
5254 This is controlled by the configure argument ``--with-universal-archs``:
5255
5256 - ``--with-universal-archs=all``: install 4-way universal
5257
5258 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5259
5260 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5261
5262 This option should be used in combination with ``--enable-universalsdk=``.
5263
5264 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005300- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
5301 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005302
Christian Heimese74c8f22008-04-19 02:23:57 +00005303- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5304
Georg Brandl3ee81df2008-05-17 18:14:43 +00005305- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
5306 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005307

Georg Brandl3ee81df2008-05-17 18:14:43 +00005314- Issue #1631171: Re-implement the 'warnings' module in C (the
5315 original Python code has been kept as backup). This will allow for
5316 using the 'warning's machinery in such places as the parser where
5317 use of pure Python code is not possible. Both the ``showarning()``
5318 and ``formatwarning()`` gain an optional 'line' argument which is
5319 not called by default for backwards-compatibility reasons. Setting
5320 ``warnings.showwarning()`` to an implementation that lacks support
5321 for the ``line`` argument will raise a DeprecationWarning.

5345
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005346- The getpass module has been improved on Unix. It now uses /dev/tty
5347 by default and uses stderr instead of stdout. A GetPassWarning is
5348 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005349

Georg Brandl3ee81df2008-05-17 18:14:43 +00005363- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005364 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005384- Issue #2550: The approach used by client/server code for obtaining
5385 ports to listen on in network-oriented tests has been refined in an
5386 effort to facilitate running multiple instances of the entire
5387 regression test suite in parallel without issue.
5388 test_support.bind_port() has been fixed such that it will always
5389 return a unique port -- which wasn't always the case with the
5390 previous implementation, especially if socket options had been set
5391 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5392 new implementation of bind_port() will actually raise an exception
5393 if it is passed an AF_INET/SOCK_STREAM socket with either the
5394 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5395 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5396 the socket it's been passed. This currently only applies to
5397 Windows. This option prevents any other sockets from binding to the
5398 host/port we've bound to, thus removing the possibility of the
5399 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5400 when a second SOCK_STREAM socket binds and accepts to a host/port
5401 that's already been bound by another socket. The optional preferred
5402 port parameter to bind_port() has been removed. Under no
5403 circumstances should tests be hard coding ports!
5404
5405 test_support.find_unused_port() has also been introduced, which will
5406 pass a temporary socket object to bind_port() in order to obtain an
5407 unused port. The temporary socket object is then closed and
5408 deleted, and the port is returned. This method should only be used
5409 for obtaining an unused port in order to pass to an external program
5410 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5411 a parameter to a server-oriented class that doesn't give you direct
5412 access to the underlying socket used.
5413
5414 Finally, test_support.HOST has been introduced, which should be used
5415 for the host argument of any relevant socket calls (i.e. bind and
5416 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005417
5418 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005420 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5421 test_asynchat and test_socket_ssl.
5422
Georg Brandl3ee81df2008-05-17 18:14:43 +00005423 It is now possible for multiple instances of the regression test
5424 suite to run in parallel without issue.

5692
Fred Drakea8ee94b2008-03-01 02:45:07 +00005693- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005694 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005695
Georg Brandlad61bc82008-02-23 15:11:18 +00005696- Issue #2067: file.__exit__() now calls subclasses' close() method.
5697
5698- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005699
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005700- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005701 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005702
Eric Smitha73fbe72008-02-23 03:09:44 +00005703- Added the future_builtins module, which contains hex() and oct().
5704 These are the PEP 3127 version of these functions, designed to be
5705 compatible with the hex() and oct() builtins from Python 3.0. They
5706 differ slightly in their output formats from the existing, unchanged
5707 Python 2.6 builtins. The expected usage of the future_builtins
5708 module is:
5709 from future_builtins import hex, oct
5710
Eric Smith7ef40bf2008-02-20 23:34:22 +00005711- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5712 exponents for exponents with absolute value < 100. Follows C99
5713 standard. This is a change on Windows, which would use 3 digits.
5714 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5715 so that any alterations it does to the resulting string will be
5716 available in stringlib/formatter.h (for float.__format__).
5717
Eric Smith5a3c1352008-02-19 13:21:56 +00005718- Implemented PEP 3101, Advanced String Formatting. This adds a new
5719 builtin format(); a format() method for str and unicode; a
5720 __format__() method to object, str, unicode, int, long, float, and
5721 datetime; the class string.Formatter; and the C API
5722 PyObject_Format().
5723
Georg Brandl3ee81df2008-05-17 18:14:43 +00005724- Fixed several potential crashes, all caused by specially crafted
5725 __del__ methods exploiting objects in temporarily inconsistent
5726 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005727
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005728- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005729 prevent a possible crash: an Abstract Base Class would try to access
5730 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005731
Georg Brandl3ee81df2008-05-17 18:14:43 +00005732- Fixed repr() and str() of complex numbers with infinity or nan as
5733 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005734
Georg Brandl3ee81df2008-05-17 18:14:43 +00005735- Clear all free lists during a gc.collect() of the highest generation
5736 in order to allow pymalloc to free more arenas. Python may give back
5737 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005738
Georg Brandl3ee81df2008-05-17 18:14:43 +00005739- Issue #2045: Fix an infinite recursion triggered when printing a
5740 subclass of collections.defaultdict, if its default_factory is set
5741 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005742
Christian Heimesf75dbef2008-02-08 00:11:31 +00005743- Fixed a minor memory leak in dictobject.c. The content of the free
5744 list was not freed on interpreter shutdown.
5745
Georg Brandl21e99f42010-03-07 15:23:59 +00005746- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005747 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5750 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005751 to compact the internal free lists of pre-allocted ints and floats.
5752
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5754 calls. Python expected the return type int but the fork familie
5755 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005756
Georg Brandl3ee81df2008-05-17 18:14:43 +00005757- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5758 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005759
Georg Brandl3ee81df2008-05-17 18:14:43 +00005760- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5761 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5767 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005768
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769- Patch #1473257: generator objects gain a gi_code attribute. This is
5770 the same object as the func_code attribute of the function that
5771 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- Issue #1920: "while 0" statements were completely removed by the
5774 compiler, even in the presence of an "else" clause, which is
5775 supposed to be run when the condition is false. Now the compiler
5776 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005777
Guido van Rossumeead05f2008-01-24 18:21:02 +00005778- A few crashers fixed: weakref_in_del.py (issue #1377858);
5779 loosing_dict_ref.py (issue #1303614, test67.py);
5780 borrowed_ref_[34].py (not in tracker).
5781
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005782- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005783 suppressed while an extension is loaded by calling SetErrorMode in
5784 dynload_win.c. The error is still reported properly.
5785
Georg Brandl3ee81df2008-05-17 18:14:43 +00005786- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005787 several extension methods and modules do not work without unicode
5788 support.
5789
Georg Brandl26543b12008-01-21 18:36:51 +00005790- Issue #1882: when compiling code from a string, encoding cookies in the
5791 second line of code were not always recognized correctly.
5792
Georg Brandl14404b62008-01-19 19:27:05 +00005793- Issue #1679: "0x" was taken as a valid integer literal.
5794
Georg Brandl6caad7d2008-01-26 14:19:22 +00005795- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005796 added.
5797
Christian Heimesc94e2b52008-01-14 04:13:37 +00005798- sys.float_info / PyFloat_GetInfo: The floating point information
5799 object was converted from a dict to a specialized structseq object.
5800
Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Patch #1816: Added sys.flags structseq. It exposes the status of
5802 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005803
Georg Brandl3ee81df2008-05-17 18:14:43 +00005804- Objects/structseq.c: Implemented new structseq representation. The
5805 patch makes structseqs (e.g. the return value of os.stat) more
5806 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005807
Georg Brandl3ee81df2008-05-17 18:14:43 +00005808- Patch #1700288: added a type attribute cache that caches method
5809 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005810

5817 envvar and sys.dont_write_bytecode attribute. All these can be set
5818 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005819
Georg Brandl3ee81df2008-05-17 18:14:43 +00005820- Improve some exception messages when Windows fails to load an
5821 extension module. Now we get for example '%1 is not a valid Win32
5822 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005829- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005830 and INF. float("nan"), float("inf") and float("-inf") now work on
5831 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005832
Georg Brandl3ee81df2008-05-17 18:14:43 +00005833- Compiler now generates simpler and faster code for dictionary
5834 literals. The oparg for BUILD_MAP now indicates an estimated
5835 dictionary size. There is a new opcode, STORE_MAP, for adding
5836 entries to the dictionary.

5885 possibility of having a self-referential tuple, which is possible
5886 from C code. Nor did object's tp_str consider that a type's tp_str
5887 could do something that could lead to an inifinite recursion.
5888 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5889 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005891- Issue #1164: It was possible to trigger deadlock when using the
5892 'print' statement to write to a file since the GIL was not released
5893 as needed. Now PyObject_Print() does the right thing along with
5894 various tp_print implementations of the built-in types and those in
5895 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005897- Issue #1147: Exceptions were directly allowing string exceptions in
5898 their throw() method even though string exceptions no longer
5899 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005901- Issue #1096: Prevent a segfault from getting the repr of a very
5902 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005903
Brett Cannon1e534b52007-09-07 04:18:30 +00005904- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005905 PyObject_Call() never calling back out to Python code to trigger
5906 recursion depth updates/checks. Required the creation of a static
5907 RuntimeError instance in case normalizing an exception put the
5908 recursion check value past its limit. Fixes crashers
5909 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005924- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005925 __*__ attributes. (Some already existed, e.g., __doc__ and
5926 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005927
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005928- Add -3 option to the interpreter to warn about features that are
5929 deprecated and will be changed/removed in Python 3.0.
5930
Georg Brandl2134e752007-05-21 20:34:16 +00005931- Patch #1686487: you can now pass any mapping after '**' in function
5932 calls.
5933
Collin Winter62903052007-05-18 23:11:24 +00005934- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005935 "except E as target:". This is to provide forwards compatibility
5936 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005937
Brett Cannon229cee22007-05-05 01:34:02 +00005938- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005943- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005944 setting a plain string, ie don't expand to single letter identifiers.
5945
Raymond Hettinger13936692007-04-11 18:40:58 +00005946- Request #1191699: Slices can now be pickled.
5947
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005948- Request #1193128: str.translate() now allows a None argument for
5949 translations that only remove characters without re-mapping the
5950 remaining characters.
5951
Georg Brandl5cb76c12007-03-21 09:00:39 +00005952- Patch #1682205: a TypeError while unpacking an iterable is no longer
5953 masked by a generic one with the message "unpack non-sequence".
5954
Neal Norwitzaa754b72007-03-21 06:39:48 +00005955- Remove unused file Python/fmod.c.
5956
Guido van Rossum143b5642007-03-23 04:58:42 +00005957- Bug #1683368: The object.__init__() and object.__new__() methods are
5958 now stricter in rejecting excess arguments. The only time when
5959 either allows excess arguments is when it is not overridden and the
5960 other one is. For backwards compatibility, when both are
5961 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005962 warning later). Also, type.__init__() insists on the same signature
5963 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005964
Georg Brandl3ee81df2008-05-17 18:14:43 +00005965- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5966 object to complex using its __complex__() method before falling back
5967 to the __float__() method. Therefore, the functions in the cmath
5968 module now can operate on objects that define a __complex__()
5969 method.

5986
Georg Brandl7b9c5552007-03-12 14:30:05 +00005987- Bug #1678647: write a newline after printing an exception in any
5988 case, even when converting the value to a string failed.
5989
Georg Brandl871f1bc2007-03-12 13:17:36 +00005990- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991 its argument, if it exists. If not, it will work like before. This
5992 allows customizing the output of dir() in the presence of a
5993 __getattr__().

6002 parthensized forms. This means complex(repr(x)) now works instead of
6003 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006004
Georg Brandlaa2321b2007-03-07 00:40:28 +00006005- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006006 makes the filenames the warning module prints much more sensible
6007 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006008

Georg Brandl0fca97a2007-03-05 22:28:08 +00006020- Patch #1674228: when assigning a slice (old-style), check for the
6021 sq_ass_slice instead of the sq_slice slot.
6022
Georg Brandl3ee81df2008-05-17 18:14:43 +00006023- When printing an unraisable error, don't print exceptions. before
6024 the name. This duplicates the behavior whening normally printing
6025 exceptions.

6654 exception.

6937 obtained from the TLS negotiation itself. Patch contributed by Bill
6938 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006939
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006941 that the SMTP.starttls() caller no longer needs to call ehlo()
6942 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006943 does not claim to support starttls. Adds the
6944 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7025 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7026 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007043 time so that opening a database previously created with the DB_DUP
7044 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7045 opens. Specifically: dictionary assignment to a DB object will
7046 replace all values for a given key when the database allows
7047 duplicate values. DB users should use DB.put(k, v) when they want
7048 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007049

7055 characters with ASCII value less than 32. Also, it correctly quotes
7056 dots only if they occur on a single line, as opposed to the previous
7057 behavior of quoting dots if they are the second character of any
7058 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007059

7381-----
7382
Georg Brandl3ee81df2008-05-17 18:14:43 +00007383- Unified naming convention for free lists and their limits. All free
7384 lists in Object/ are named ``free_list``, the counter ``numfree``
7385 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7386 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007387
Georg Brandl3ee81df2008-05-17 18:14:43 +00007388- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7389 to ``PyTuple_SetItem``, it can be used to populate a brand new
7390 frozenset; but it does not steal a reference to the added item.

7395 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7396 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007397
7398- Patch #1720595: add T_BOOL to the range of structmember types.
7399
7400- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7401 ``PyFloat_GetInfo()`` to the float API.
7402
Georg Brandl3ee81df2008-05-17 18:14:43 +00007403- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7404 of w# format code incorrectly truncated the length to an int, even
7405 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7406 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007407
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7409 Py_TYPE and Py_REFCNT.

7426- Fix some leftovers from the conversion from int to Py_ssize_t
7427 (relevant to strings and sequences of more than 2**31 items).
7428
7429- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7430 outside of pystate.c and should not be necessary.
7431
Georg Brandl3ee81df2008-05-17 18:14:43 +00007432- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7433 absolute imports. In earlier versions they might have used relative
7434 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007435
Georg Brandl3ee81df2008-05-17 18:14:43 +00007436- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7437 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007438
Georg Brandl3ee81df2008-05-17 18:14:43 +00007439- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007446- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7447 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7448 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7449 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007450

Georg Brandl3ee81df2008-05-17 18:14:43 +00007464- Removed the macfs module. It had been deprecated since Python 2.5.
7465 This lead to the deprecation of macostools.touched() as it relied
7466 solely on macfs and was a no-op under OS X.
