Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000290 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
291 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
292 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

312Core and Builtins
313-----------------
314
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000315- Issue #7301: Add environment variable $PYTHONWARNINGS.
316
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000317- Issue #8329: Don't return the same lists from select.select when no fds are
318 changed.
319
Georg Brandlfee0f442010-05-22 21:26:21 +0000320- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000321 on 64-bit machines. The shift count for either left or right shift is
322 permitted to be up to sys.maxsize.
323
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000324- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000328- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
329
Georg Brandlfee0f442010-05-22 21:26:21 +0000330- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
331 with a non-empty format string. This is an effort to future-proof user
332 code. If a derived class does not currently implement __format__ but later
333 adds its own __format__, it would most likely break user code that had
334 supplied a format string. This will be changed to a DeprecationWaring in
335 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000336
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000337- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000362- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000363 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

367
Georg Brandlfee0f442010-05-22 21:26:21 +0000368- Issue #8257: The Decimal construct now accepts a float instance directly,
369 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000370
371 >>> Decimal(1.1)
372 Decimal('1.100000000000000088817841970012523233890533447265625')
373
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000374- collections.Counter() now supports a subtract() method.
375
Georg Brandlfee0f442010-05-22 21:26:21 +0000376- The functools module now has a total_ordering() class decorator to simplify
377 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000378
Georg Brandlfee0f442010-05-22 21:26:21 +0000379- The functools module also adds cmp_to_key() as a tool to transition old-style
380 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000381
Georg Brandlfee0f442010-05-22 21:26:21 +0000382- Issue #8294: The Fraction constructor now accepts Decimal and float instances
383 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000384
Georg Brandlfee0f442010-05-22 21:26:21 +0000385- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
386 InvalidOperation instead of returning False. (Comparisons involving a quiet
387 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
388 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000389
Georg Brandlfee0f442010-05-22 21:26:21 +0000390- Issue #2531: Comparison operations between floats and Decimal instances now
391 return a result based on the numeric values of the operands; previously they
392 returned an arbitrary result based on the relative ordering of id(float) and
393 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000394
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000395- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000396 argument `-` which tells it to read files to compile from stdin. Each line is
397 read on demand and the named file is compiled immediately. (Original patch by
398 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000399
Georg Brandlfee0f442010-05-22 21:26:21 +0000400- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000403- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
404 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000405 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000406
Georg Brandlfee0f442010-05-22 21:26:21 +0000407- Comparisons using one of <, <=, >, >= between a complex instance and a
408 Fractions instance now raise TypeError instead of returning True/False. This
409 makes Fraction <=> complex comparisons consistent with int <=> complex, float
410 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000411

420
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000421- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000422 didn't support chflags() (for example ZFS under FreeBSD). The error is now
423 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000424
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000425- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000465- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000466 for ``TimedRotatingFileHandler`` by using the modification time of an existing
467 log file to compute the next rollover time. If the log file does not exist,
468 the current time is used as the basis for the computation.

515 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000517 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
518 inconsistent: __int__ was used for some integer codes but not for others, and
519 the set of integer codes for which it was used differed between native packing
520 and standard packing.)

745 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000746 library would return a bogus result; on Solaris, it was possible to crash the
747 interpreter. Patch by Stefan Krah.

Mark Dickinson36ecd672010-01-29 17:11:39 +0000759
Georg Brandlba83f822010-03-14 09:50:54 +0000760- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
761 and add the additional members returned in an OSVERSIONINFOEX structure. The
762 new members are service_pack_major, service_pack_minor, suite_mask, and
763 product_type.
Eric Smithee931b72010-01-27 00:28:29 +0000764
Georg Brandlba83f822010-03-14 09:50:54 +0000765- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
766 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
767 returning NULL. The macro now returns a statically allocated empty string
768 instead.

778 strings,
779 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
780 numeric strings corresponding to subnormal values,
781 (3) a memory leak for some values large enough to cause overflow, and
782 (4) a number of flaws that could lead to incorrectly rounded results.
783
784- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
785 option is not used.

797 interpreter shutdown.
798
Georg Brandlba83f822010-03-14 09:50:54 +0000799- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
800 XML processing instructions and comments. These raw characters are allowed
801 by the XML specification, and are necessary when outputting e.g. PHP code in
802 a processing instruction. Patch by Neil Muller.

Vinay Sajip0e6e97d2010-02-04 20:23:45 +0000809
Antoine Pitroud840e512010-02-04 20:20:18 +0000810- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000811 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000812 Also, raise ValueError rather than TypeError when an unknown TIPC address
813 type is specified. Patch by Brian Curtin.
814
Vinay Sajip28c382f2010-02-04 18:48:53 +0000815- logging: Implemented PEP 391.
816
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000817- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000818 file position when calling `truncate()`. It would previously change the file
819 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000820 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
821
Benjamin Petersone06f7112010-01-28 02:15:02 +0000822- UserDict is now a new-style class.
823
Georg Brandlba83f822010-03-14 09:50:54 +0000824- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
825 class used to represent files stored inside an archive. The new
826 implementation is significantly faster and can be wrapped in a
827 ``io.BufferedReader`` object for more speedups. It also solves an issue
828 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
829 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000830
Benjamin Peterson2deb5c72010-01-27 02:16:42 +0000831- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Georg Brandlba83f822010-03-14 09:50:54 +0000836- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
837 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000838
Georg Brandlba83f822010-03-14 09:50:54 +0000839- Issue #7748: Since unicode values are supported for some metadata options in
840 Distutils, the DistributionMetadata get_* methods will now return an utf-8
841 encoded string for them. This ensures that the upload and register commands
842 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000843
Georg Brandlba83f822010-03-14 09:50:54 +0000844- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000845 headers in multipart/signed MIME parts, which fixes one of the sources of
846 invalid modifications to such parts by Generator.

916Core and Builtins
917-----------------
918
Georg Brandlba83f822010-03-14 09:50:54 +0000919- The ``__complex__()`` method is now looked up on the class of instances to
920 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000921
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000922- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
923 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
924
Mark Dickinson1b34d252010-01-01 17:27:30 +0000925- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000926 DeprecationWarning when passed a float argument where an integer was expected.
927 These functions and methods now raise TypeError instead. The majority of the
928 effects of this change are in the extension modules, but some core functions
929 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
930 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000940- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
941 used to drop the time part of the result.
942
Georg Brandlba83f822010-03-14 09:50:54 +0000943- Issue #1811: Improve accuracy and cross-platform consistency for true division
944 of integers: the result of a/b is now correctly rounded for ints a and b (at
945 least on IEEE 754 platforms), and in particular does not depend on the
946 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000947
Georg Brandlba83f822010-03-14 09:50:54 +0000948- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
949 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
950 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +0000953 executables on OSX.
954
Georg Brandlba83f822010-03-14 09:50:54 +0000955 These executables now work properly with the arch(1) command: ``arch -ppc
956 python`` will start a universal binary version of python in PPC mode (unlike
957 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000958

1097 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001098
Georg Brandlba83f822010-03-14 09:50:54 +00001099- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1100 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001101

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001112
Georg Brandlba83f822010-03-14 09:50:54 +00001113- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1114 decimal string that's guaranteed to round back to x under correct rounding
1115 (with round-half-to-even rounding mode). Previously it gave a string based on
1116 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1117 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1118 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001119
Georg Brandlba83f822010-03-14 09:50:54 +00001120- Issue #7117: On almost all platforms: float-to-string and string-to-float
1121 conversions within Python are now correctly rounded. Places these conversions
1122 occur include: str for floats and complex numbers; the float and complex
1123 constructors; old-style and new-style numeric formatting; serialization and
1124 deserialization of floats and complex numbers using marshal, pickle and json;
1125 parsing of float and imaginary literals in Python code; Decimal-to-float
1126 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001127
Georg Brandlba83f822010-03-14 09:50:54 +00001128 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1129 providing correctly-rounded strtod and dtoa C functions. This code is
1130 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1131 the C compiler. There may be a small number of platforms on which correct
1132 operation of this code cannot be guaranteed, so the code is not used: notably,
1133 this applies to platforms where the C double format is not IEEE 754 binary64,
1134 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1135 and Python's configure script is unable to determine how to change the FPU
1136 precision. On these platforms conversions use the platform strtod and dtoa,
1137 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001138
Georg Brandlba83f822010-03-14 09:50:54 +00001139- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1140 uses the correctly-rounded string <-> float conversions described above (when
1141 available), and so produces correctly rounded results that will display nicely
1142 under the float repr. There are two related small changes: (1) round now
1143 accepts any class with an ``__index__()`` method for its second argument (but
1144 no longer accepts floats for the second argument), and (2) an excessively
1145 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1146 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001288
Georg Brandlba83f822010-03-14 09:50:54 +00001289 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1290 (2) parsing of strings representing infinities and nans was locale aware; and
1291 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001293- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1294 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1295 but with at least one decimal point and with a default precision
1296 of 12. Previously, the behavior the same but with a default precision of 6.
1297 This more closely matches ``str()``, and reduces surprises when adding
1298 alignment flags to the empty presentation type. This also affects the new
1299 complex.__format__ in the same way.
1300
1301- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1302 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001364 untrackable objects are not tracked by the garbage collector. This can reduce

1373 internal representation of integers, for performance reasons. Base 2**30 is
1374 enabled by default on 64-bit machines. Add --enable-big-digits option to

1461
Georg Brandl6425a2f2008-12-28 11:54:53 +00001462- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001463 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001464
Skip Montanarof205c132008-12-23 03:30:15 +00001465- Added test case to ensure attempts to read from a file opened for writing
1466 fail.
1467
Georg Brandlba83f822010-03-14 09:50:54 +00001468- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1469 elapsed times, not only when some objects are uncollectable/unreachable.

Georg Brandlba83f822010-03-14 09:50:54 +00001482- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1483 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1484 instances. On a typical machine this saves 3 bytes of memory (on average) per
1485 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001487- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1488 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1489 instead of throwing a MemoryError.
1490
Georg Brandlba83f822010-03-14 09:50:54 +00001491- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1492 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00001494- Issue #4367: Python would segfault during compiling when the unicodedata
1495 module couldn't be imported and \N escapes were present.
1496
Georg Brandlba83f822010-03-14 09:50:54 +00001497- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1498 file objects with closefd=False. The file descriptor is still kept open but
1499 the file object behaves like a closed file. The ``FileIO`` object also got a
1500 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001502- Issue #4348: Some bytearray methods returned that didn't cause any change to
1503 the bytearray, returned the same bytearray instead of a copy.
1504
Georg Brandlba83f822010-03-14 09:50:54 +00001505- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00001517- Issue #4209: Enabling unicode_literals and the print_function in the same
1518 __future__ import didn't work.
1519
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001520- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001521 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001522
Georg Brandlba83f822010-03-14 09:50:54 +00001523- On windows, ``os.chdir()`` given unicode was not working if
1524 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1525 this code path is really executed because I cannot move to such directory on
1526 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001527
Georg Brandlba83f822010-03-14 09:50:54 +00001528- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1529 element is temporarily replaced with an equivalent frozenset. But the
1530 eventual KeyError would always report the empty ``frozenset()`` as the missing
1531 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001548- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1549 returned them on 64bit platforms.
1550
Walter Dörwalded960ac2009-05-03 22:36:33 +00001551- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1552 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1553 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1554 of using the replace error handler in PyUnicode_DecodeUTF8().
1555
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001556- Issue #3739: The unicode-internal encoder now reports the number of characters
1557 consumed like any other encoder (instead of the number of bytes).
1558
Georg Brandlba83f822010-03-14 09:50:54 +00001559- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1560 allocator will be automatically disabled when running under Valgrind. This
1561 gives improved memory leak detection when running under Valgrind, while taking
1562 advantage of pymalloc at other times.

2729 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2730 neither __int__ nor __long__, TypeError used to be raised (with a

Antoine Pitrou4698d992009-05-31 14:20:14 +00002809- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2810 regression tests in parallel, shortening the total runtime.

Georg Brandlba83f822010-03-14 09:50:54 +00002812- Issue #5354: New test support function import_fresh_module() makes it easy to
2813 import both normal and optimised versions of modules. test_heapq and
2814 test_warnings have been adjusted to use it, tests for other modules with both
2815 C and Python implementations in the stdlib can be adjusted to use it over
2816 time.

2825 should cause a test to be skipped are now done using import_module from test
2826 support, which does the conversion.

2928
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002929- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2930 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2931 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2932 ``printf`` function, whereas PyString_FromFormat has an independent
2933 implementation and uses "%zd" on all platforms for size_t values.
2934 This makes a difference on win64, where ``printf`` needs "%Id" to display
2935 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002952 was correctly parsed but parsing of subsequent arguments failed.
2953
Vinay Sajip35e3b032008-09-01 14:33:59 +00002954- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002955 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2956 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2957 when given a tuple of classes as second argument, were looking up
2958 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2959 type object.

3103Core and Builtins
3104-----------------
3105
Guido van Rossumf8402962008-08-20 15:01:50 +00003106- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3107 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3108 extensions do not automatically benefit from the class attribute
3109 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3110 to their tp_flags field if they care. This is a backwards
3111 compatibility feature; in 3.0, all types will use the cache by
3112 default.
3113
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003114- Keyword arguments can now follow starred arguments. (``f(a, *args,
3115 keyword=23)`` is now valid syntax.)
3116
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003117- ctypes function pointers that are COM methods have a boolean True
3118 value again.
3119
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003120- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3121 by denying s# to parse objects that have a releasebuffer procedure,
3122 and introducing s*.
3123
Georg Brandl1e13ea92008-08-11 09:07:59 +00003124- Issue #3537: Fix an assertion failure when an empty but presized dict
3125 object was stored in the freelist.
3126
Mark Dickinsonb6467572008-08-04 21:30:09 +00003127- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3128 ValueError consistently across platforms.
3129
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003130- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3131 (64bit Unix, for example), unichr() would truncate its argument and return
3132 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3133
Neal Norwitze7d8be82008-07-31 17:17:14 +00003134- Apply security patches from Apple.
3135
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003136- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3137 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3138
Antoine Pitrou92f82162008-07-25 22:22:08 +00003139- Issue #1819: function calls with several named parameters are now on
3140 average 35% faster (as measured by pybench).
3141
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003142- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3143 the python debugger steps into a class statement: the free variables (local
3144 variables defined in an outer scope) would be deleted from the outer scope.
3145
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003146- Issue #2620: Overflow checking when allocating or reallocating memory
3147 was not always being done properly in some python types and extension
3148 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3149 all been updated to perform better checks and places in the code that
3150 would previously leak memory on the error path when such an allocation
3151 failed have been fixed.

3154-------
3155
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003156- Issue #3612: Added some missing basic types in ctypes.wintypes.
3157
Benjamin Petersone977ad42008-08-20 01:42:01 +00003158- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3159 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3160
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003161- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3162 version reported by these tools does not necessarily follow the python
3163 version numbering scheme, so the module is less strict when parsing it.
3164
Nick Coghlanf70385a2008-08-18 12:42:46 +00003165- Issue #2235: Added Py3k warnings for types which will become unhashable
3166 under the stricter __hash__ inheritance rules in 3.0. Several types
3167 which did not meet the rules for hash invariants and were already
3168 unhashable in 3.0 have now been explicitly flagged as unhashable in
3169 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3170 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3171
Brett Cannon88f801d2008-08-18 00:46:22 +00003172- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3173 imported into the module but exposed as part of the module's API.
3174
Brett Cannon7b96f072008-08-18 00:41:11 +00003175- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3176
Brett Cannon46225e72008-08-18 00:36:52 +00003177- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3178
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003179- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3180
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003181- Issue #3575: Incremental decoder's decode function now takes bytearray
3182 by using 's*' instead of 't#'.
3183
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003184- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003185 fails unicode conversion on 2nd parameter. (windows only)
3186
Facundo Batista94f243a2008-08-17 03:38:39 +00003187- Issue 2464. urllib2 now supports a malformation in the URL received
3188 in a redirect.
3189
Brett Cannonabe423e2008-08-16 21:47:07 +00003190- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003191 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003192
Facundo Batistaeb90b782008-08-16 14:44:07 +00003193- Issue #2776: fixed small issue when handling an URL with double slash
3194 after a 302 response in the case of not going through a proxy.
3195
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003196- Issue #2676: in the email package, content-type parsing was hanging on
3197 pathological input because of quadratic or exponential behaviour of a
3198 regular expression.
3199
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003200- Issue #3476: binary buffered reading through the new "io" library is now
3201 thread-safe.
3202
Brett Cannonbf3157b2008-08-14 05:00:03 +00003203- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3204 since mimetools itself is deprecated. Because modules are cached, all
3205 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3206
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003207- Issue #3134: shutil referenced undefined WindowsError symbol.
3208
Robert Schuppenies14646332008-08-10 11:01:53 +00003209- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3210 menu entries were not deleted.
3211
Brett Cannon83e81842008-08-09 23:30:55 +00003212- Copied the implementation of reduce() to _functools.reduce() to have a
3213 version that did not raise a DeprecationWarning under -3.
3214
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003215- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3216 a MemoryError rather than silently stop the iteration.
3217
Guido van Rossum59ce9012008-08-09 14:55:34 +00003218- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3219 to _sre.compile() will now be rejected. This should not affect anybody
3220 since the re.compile() function never generates invalid re-bytecode.
3221
Skip Montanaroa032bf42008-08-08 22:52:51 +00003222- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3223 upon first access it can be automatically initialized from the csv file if
3224 it wasn't initialized during instantiation.
3225
Brett Cannon3aa2a492008-08-06 22:28:09 +00003226- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3227 the reload() built-in has been removed.
3228
Brett Cannon7e30b672008-08-04 21:52:25 +00003229- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003230 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003231 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3232 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3233 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3234 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3235 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003236
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003237- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3238 raised an AttributeError.
3239
Benjamin Peterson01a24322008-07-28 23:35:27 +00003240- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003241 asking for a specific length. This problem only affected files opened
3242 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003243
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003244- Issue #3449: Update decimal module to use most recent specification
3245 (v. 1.68) and tests (v. 2.58) from IBM.
3246
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003247- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3248
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003249- Issue 1592: Improve error reporting when operations are attempted
3250 on a closed shelf.
3251
Georg Brandlf9efabb2008-07-23 15:16:45 +00003252- Deprecate the "ast" parser function aliases.
3253
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003254- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3255
3256- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3257 invalid arguments.
3258
3259- Issue #3302: Fix several crashes when calling locale's gettext functions
3260 with None arguments.
3261
3262- Issue #3389: Allow resolving dotted names for handlers in logging
3263 configuration files.
3264
3265- Deprecate the sunaudio module for removal in Python 3.0.
3266
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003267- Issue #3394: zipfile.writestr sets external attributes when passed a
3268 file name rather than a ZipInfo instance, so files are extracted with
3269 mode 0600 rather than 000 under Unix.
3270
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003271- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3272 argument in python 2.5, this broke code that subclassed Popen to include its
3273 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3281-------------
3282
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003283- Issue #2235: the C API function PyObject_HashNotImplemented and its
3284 interaction with the tp_hash slot (added in 2.6b2) are now documented
3285
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003286- Issue #643841: The language reference now provides more detailed
3287 coverage of the lookup process for special methods. The disclaimers
3288 regarding lack of coverage of new-style classes have also been
3289 removed, since the coverage is now fairly reasonable.

3298-----------------
3299
Georg Brandl3e483f62008-07-16 22:57:41 +00003300- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3301 its methods now allow for items objects that can be converted to
3302 an integer using operator.index().
3303
Mark Dickinson64b7e502008-07-16 09:40:03 +00003304- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3305 produced a ValueError instead of giving the correct float.
3306
Eric Smitha5fa5a22008-07-16 00:11:49 +00003307- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3308 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3309
Mark Dickinson7103aa42008-07-15 19:08:33 +00003310- Issue #3008: the float type has a new instance method 'float.hex'
3311 and a new class method 'float.fromhex' to convert floating-point
3312 numbers to and from hexadecimal strings, respectively.
3313
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003314- Issue #2235: __hash__ is once again inherited by default. To allow
3315 collections.Hashable to remain meaningful in the presence of the
3316 default hash implementation (object.__hash__), it is now possible
3317 to explicit block inheritance of hash by setting __hash__=None at
3318 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3319 level.
3320
Nick Coghlanb028f502008-07-13 14:52:36 +00003321- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3322 the parent module cannot be found while performing an absolute import.
3323 This means that an incorrectly defined __package__ attribute will
3324 now only prevent relative imports in that module rather than causing
3325 all imports from that module to fail.
3326
Nick Coghlan14ff9942008-07-08 14:21:42 +00003327- Issue #2517: Allow unicode messages in Exceptions again by correctly
3328 bypassing the instance dictionary when looking up __unicode__ on
3329 new-style classes.
3330
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003331- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3332 set to a custom object whose write() method happens to install
3333 another file in sys.stdout.
3334
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003335- Issue #3088: Corrected a race condition in classes derived from
3336 threading.local: the first member set by a thread could be saved in
3337 another thread's dictionary.
3338
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003339- Issue #3004: Minor change to slice.indices(): the start and stop
3340 arguments are now treated identically, making the behaviour easier
3341 to describe and understand. For example, slice(None, -10,
3342 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3343 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3344 10, -1).
3345
Georg Brandl278fc502008-07-19 12:46:12 +00003346- Issue #3219: Calling a function with repeated keyword arguments,
3347 f(a=2, a=23), would not cause a syntax error. This was a regression
3348 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003349
Georg Brandl278fc502008-07-19 12:46:12 +00003350- Issue #2862: Make int and float freelist management consistent with
3351 other freelists. Changes their CompactFreeList apis into
3352 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003353

3355-------
3356
Thomas Heller57adf222008-08-14 19:10:48 +00003357- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3358 api functions without holding the GIL, which could lead to a fatal
3359 error when they failed.
3360
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003361- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003369- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3370 ForkingPickler.register() to resolve conflict with ctypes.
3371
Vinay Sajip51e65192008-07-18 09:01:10 +00003372- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003373
Thomas Heller880f5292008-07-15 19:39:38 +00003374- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3375 a valid dlerror() message.
3376
Thomas Heller2bad6572008-07-15 17:19:50 +00003377- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3378 incomplete structure was created.
3379
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003380- Issue #3339: dummy_thread.acquire() should not return None.
3381
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003382- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3383
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003384- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003385
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003386- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3387 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003388 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003389 content-length. The problem had been corrected in the 2.4 branch, but never

3797 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003798 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003799
3800 This is controlled by the configure argument ``--with-universal-archs``:
3801
3802 - ``--with-universal-archs=all``: install 4-way universal
3803
3804 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3805
3806 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3807
3808 This option should be used in combination with ``--enable-universalsdk=``.
3809
3810 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 +00003860- Issue #1631171: Re-implement the 'warnings' module in C (the
3861 original Python code has been kept as backup). This will allow for
3862 using the 'warning's machinery in such places as the parser where
3863 use of pure Python code is not possible. Both the ``showarning()``
3864 and ``formatwarning()`` gain an optional 'line' argument which is
3865 not called by default for backwards-compatibility reasons. Setting
3866 ``warnings.showwarning()`` to an implementation that lacks support
3867 for the ``line`` argument will raise a DeprecationWarning.

3891
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003892- The getpass module has been improved on Unix. It now uses /dev/tty
3893 by default and uses stderr instead of stdout. A GetPassWarning is
3894 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003910 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003930- Issue #2550: The approach used by client/server code for obtaining
3931 ports to listen on in network-oriented tests has been refined in an
3932 effort to facilitate running multiple instances of the entire
3933 regression test suite in parallel without issue.
3934 test_support.bind_port() has been fixed such that it will always
3935 return a unique port -- which wasn't always the case with the
3936 previous implementation, especially if socket options had been set
3937 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3938 new implementation of bind_port() will actually raise an exception
3939 if it is passed an AF_INET/SOCK_STREAM socket with either the
3940 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3941 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3942 the socket it's been passed. This currently only applies to
3943 Windows. This option prevents any other sockets from binding to the
3944 host/port we've bound to, thus removing the possibility of the
3945 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3946 when a second SOCK_STREAM socket binds and accepts to a host/port
3947 that's already been bound by another socket. The optional preferred
3948 port parameter to bind_port() has been removed. Under no
3949 circumstances should tests be hard coding ports!
3950
3951 test_support.find_unused_port() has also been introduced, which will
3952 pass a temporary socket object to bind_port() in order to obtain an
3953 unused port. The temporary socket object is then closed and
3954 deleted, and the port is returned. This method should only be used
3955 for obtaining an unused port in order to pass to an external program
3956 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3957 a parameter to a server-oriented class that doesn't give you direct
3958 access to the underlying socket used.
3959
3960 Finally, test_support.HOST has been introduced, which should be used
3961 for the host argument of any relevant socket calls (i.e. bind and
3962 connect).

3970 suite to run in parallel without issue.

4236Core and builtins
4237-----------------
4238
Fred Drakea8ee94b2008-03-01 02:45:07 +00004239- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004240 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004241
Georg Brandlad61bc82008-02-23 15:11:18 +00004242- Issue #2067: file.__exit__() now calls subclasses' close() method.
4243
4244- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004245
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004246- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004247 issue 215555 for a discussion.
4248
Eric Smitha73fbe72008-02-23 03:09:44 +00004249- Added the future_builtins module, which contains hex() and oct().
4250 These are the PEP 3127 version of these functions, designed to be
4251 compatible with the hex() and oct() builtins from Python 3.0. They
4252 differ slightly in their output formats from the existing, unchanged
4253 Python 2.6 builtins. The expected usage of the future_builtins
4254 module is:
4255 from future_builtins import hex, oct
4256
Eric Smith7ef40bf2008-02-20 23:34:22 +00004257- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4258 exponents for exponents with absolute value < 100. Follows C99
4259 standard. This is a change on Windows, which would use 3 digits.
4260 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4261 so that any alterations it does to the resulting string will be
4262 available in stringlib/formatter.h (for float.__format__).
4263
Eric Smith5a3c1352008-02-19 13:21:56 +00004264- Implemented PEP 3101, Advanced String Formatting. This adds a new
4265 builtin format(); a format() method for str and unicode; a
4266 __format__() method to object, str, unicode, int, long, float, and
4267 datetime; the class string.Formatter; and the C API
4268 PyObject_Format().
4269
Georg Brandl3ee81df2008-05-17 18:14:43 +00004270- Fixed several potential crashes, all caused by specially crafted
4271 __del__ methods exploiting objects in temporarily inconsistent
4272 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004273
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004274- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004275 prevent a possible crash: an Abstract Base Class would try to access
4276 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004277
Georg Brandl3ee81df2008-05-17 18:14:43 +00004278- Fixed repr() and str() of complex numbers with infinity or nan as
4279 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004280
Georg Brandl3ee81df2008-05-17 18:14:43 +00004281- Clear all free lists during a gc.collect() of the highest generation
4282 in order to allow pymalloc to free more arenas. Python may give back
4283 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004284
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285- Issue #2045: Fix an infinite recursion triggered when printing a
4286 subclass of collections.defaultdict, if its default_factory is set
4287 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004288
Christian Heimesf75dbef2008-02-08 00:11:31 +00004289- Fixed a minor memory leak in dictobject.c. The content of the free
4290 list was not freed on interpreter shutdown.
4291
Georg Brandl21e99f42010-03-07 15:23:59 +00004292- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004294
Georg Brandl3ee81df2008-05-17 18:14:43 +00004295- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4296 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004297 to compact the internal free lists of pre-allocted ints and floats.
4298
Georg Brandl3ee81df2008-05-17 18:14:43 +00004299- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4300 calls. Python expected the return type int but the fork familie
4301 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004302
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4304 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004305
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4307 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004308
Georg Brandl3ee81df2008-05-17 18:14:43 +00004309- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4310 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004311
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4313 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004314
Georg Brandl3ee81df2008-05-17 18:14:43 +00004315- Patch #1473257: generator objects gain a gi_code attribute. This is
4316 the same object as the func_code attribute of the function that
4317 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004318
Georg Brandl3ee81df2008-05-17 18:14:43 +00004319- Issue #1920: "while 0" statements were completely removed by the
4320 compiler, even in the presence of an "else" clause, which is
4321 supposed to be run when the condition is false. Now the compiler
4322 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004323
Guido van Rossumeead05f2008-01-24 18:21:02 +00004324- A few crashers fixed: weakref_in_del.py (issue #1377858);
4325 loosing_dict_ref.py (issue #1303614, test67.py);
4326 borrowed_ref_[34].py (not in tracker).
4327
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004328- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004329 suppressed while an extension is loaded by calling SetErrorMode in
4330 dynload_win.c. The error is still reported properly.
4331
Georg Brandl3ee81df2008-05-17 18:14:43 +00004332- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004333 several extension methods and modules do not work without unicode
4334 support.
4335
Georg Brandl26543b12008-01-21 18:36:51 +00004336- Issue #1882: when compiling code from a string, encoding cookies in the
4337 second line of code were not always recognized correctly.
4338
Georg Brandl14404b62008-01-19 19:27:05 +00004339- Issue #1679: "0x" was taken as a valid integer literal.
4340
Georg Brandl6caad7d2008-01-26 14:19:22 +00004341- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004342 added.
4343
Christian Heimesc94e2b52008-01-14 04:13:37 +00004344- sys.float_info / PyFloat_GetInfo: The floating point information
4345 object was converted from a dict to a specialized structseq object.
4346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- Patch #1816: Added sys.flags structseq. It exposes the status of
4348 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004349
Georg Brandl3ee81df2008-05-17 18:14:43 +00004350- Objects/structseq.c: Implemented new structseq representation. The
4351 patch makes structseqs (e.g. the return value of os.stat) more
4352 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004353
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Patch #1700288: added a type attribute cache that caches method
4355 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004356
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004357- Bug #1776: __import__() no longer accepts filenames on any platform.
4358 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004359
Georg Brandlaed6c662008-01-07 17:25:53 +00004360- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4361
Georg Brandl3ee81df2008-05-17 18:14:43 +00004362- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4363 envvar and sys.dont_write_bytecode attribute. All these can be set
4364 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004365
Georg Brandl3ee81df2008-05-17 18:14:43 +00004366- Improve some exception messages when Windows fails to load an
4367 extension module. Now we get for example '%1 is not a valid Win32
4368 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004369
Georg Brandl3ee81df2008-05-17 18:14:43 +00004370- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004372- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4373 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004374
Christian Heimes0a8143f2007-12-18 23:22:54 +00004375- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004376 and INF. float("nan"), float("inf") and float("-inf") now work on
4377 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004378
Georg Brandl3ee81df2008-05-17 18:14:43 +00004379- Compiler now generates simpler and faster code for dictionary
4380 literals. The oparg for BUILD_MAP now indicates an estimated
4381 dictionary size. There is a new opcode, STORE_MAP, for adding
4382 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004383
Georg Brandl3ee81df2008-05-17 18:14:43 +00004384- Issue #1638: %zd configure test fails on Linux.

4390 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004391
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004392- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004393 SystemError.
4394
Nick Coghlanef01d822007-12-03 12:55:17 +00004395- PEP 366: Allow explicit relative imports when executing modules
4396 inside packages with the -m switch via a new module level
4397 __package__ attribute.
4398
Georg Brandl3ee81df2008-05-17 18:14:43 +00004399- Issue #1402: Fix a crash on exit, when another thread is still
4400 running, and if the deallocation of its frames somehow calls the
4401 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004402

4412 file can now be directly executed by passing their name to the
4413 interpreter. The directory/zipfile is automatically inserted as the
4414 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004415
Georg Brandl3ee81df2008-05-17 18:14:43 +00004416- Issue #1265: Fix a problem with sys.settrace, if the tracing
4417 function uses a generator expression when at the same time the
4418 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004419
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004420- sets and frozensets now have an isdisjoint() method.
4421
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004422- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004424- Fix warnings found by the new version of the Coverity checker.
4425
Georg Brandl21e99f42010-03-07 15:23:59 +00004426- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4428 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004429
Georg Brandl3ee81df2008-05-17 18:14:43 +00004430- Issue #1686386: Tuple's tp_repr did not take into account the
4431 possibility of having a self-referential tuple, which is possible
4432 from C code. Nor did object's tp_str consider that a type's tp_str
4433 could do something that could lead to an inifinite recursion.
4434 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4435 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004436
Georg Brandl3ee81df2008-05-17 18:14:43 +00004437- Issue #1164: It was possible to trigger deadlock when using the
4438 'print' statement to write to a file since the GIL was not released
4439 as needed. Now PyObject_Print() does the right thing along with
4440 various tp_print implementations of the built-in types and those in
4441 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004442
Georg Brandl3ee81df2008-05-17 18:14:43 +00004443- Issue #1147: Exceptions were directly allowing string exceptions in
4444 their throw() method even though string exceptions no longer
4445 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00004450- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004451 PyObject_Call() never calling back out to Python code to trigger
4452 recursion depth updates/checks. Required the creation of a static
4453 RuntimeError instance in case normalizing an exception put the
4454 recursion check value past its limit. Fixes crashers
4455 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004456
Georg Brandl3ee81df2008-05-17 18:14:43 +00004457- Patch #1031213: Decode source line in SyntaxErrors back to its

4461 with %G.
4462
Georg Brandl3ee81df2008-05-17 18:14:43 +00004463- Prevent expandtabs() on string and unicode objects from causing a
4464 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004470- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004471 __*__ attributes. (Some already existed, e.g., __doc__ and
4472 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004473
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004474- Add -3 option to the interpreter to warn about features that are
4475 deprecated and will be changed/removed in Python 3.0.
4476
Georg Brandl2134e752007-05-21 20:34:16 +00004477- Patch #1686487: you can now pass any mapping after '**' in function
4478 calls.
4479
Collin Winter62903052007-05-18 23:11:24 +00004480- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004481 "except E as target:". This is to provide forwards compatibility
4482 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004483
Brett Cannon229cee22007-05-05 01:34:02 +00004484- Deprecate BaseException.message as per PEP 352.
4485
Georg Brandl3ee81df2008-05-17 18:14:43 +00004486- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004487 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004488
Vinay Sajip8549ce32007-05-06 17:53:37 +00004489- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004490 setting a plain string, ie don't expand to single letter identifiers.
4491
Raymond Hettinger13936692007-04-11 18:40:58 +00004492- Request #1191699: Slices can now be pickled.
4493
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004494- Request #1193128: str.translate() now allows a None argument for
4495 translations that only remove characters without re-mapping the
4496 remaining characters.
4497
Georg Brandl5cb76c12007-03-21 09:00:39 +00004498- Patch #1682205: a TypeError while unpacking an iterable is no longer
4499 masked by a generic one with the message "unpack non-sequence".
4500
Neal Norwitzaa754b72007-03-21 06:39:48 +00004501- Remove unused file Python/fmod.c.
4502
Guido van Rossum143b5642007-03-23 04:58:42 +00004503- Bug #1683368: The object.__init__() and object.__new__() methods are
4504 now stricter in rejecting excess arguments. The only time when
4505 either allows excess arguments is when it is not overridden and the
4506 other one is. For backwards compatibility, when both are
4507 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004508 warning later). Also, type.__init__() insists on the same signature
4509 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004510
Georg Brandl3ee81df2008-05-17 18:14:43 +00004511- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4512 object to complex using its __complex__() method before falling back
4513 to the __float__() method. Therefore, the functions in the cmath
4514 module now can operate on objects that define a __complex__()
4515 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004516
Georg Brandl3ee81df2008-05-17 18:14:43 +00004517- Patch #1623563: allow __class__ assignment for classes with
4518 __slots__. The old and the new class are still required to have the
4519 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004520

4525 ``object.__reduce_ex__()`` is called with an object that is faking
4526 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Patch #1680015: Don't modify __slots__ tuple if it contains an
4529 unicode name.

4532
Georg Brandl7b9c5552007-03-12 14:30:05 +00004533- Bug #1678647: write a newline after printing an exception in any
4534 case, even when converting the value to a string failed.
4535
Georg Brandl871f1bc2007-03-12 13:17:36 +00004536- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004537 its argument, if it exists. If not, it will work like before. This
4538 allows customizing the output of dir() in the presence of a
4539 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004540
Collin Winter276887b2007-03-12 16:11:39 +00004541- Patch #922167: Python no longer segfaults when faced with infinitely
4542 self-recursive reload() calls (as reported by bug #742342).
4543

4548 parthensized forms. This means complex(repr(x)) now works instead of
4549 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004550
Georg Brandlaa2321b2007-03-07 00:40:28 +00004551- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004552 makes the filenames the warning module prints much more sensible
4553 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004554
Georg Brandl49aafc92007-03-07 00:34:46 +00004555- Variant of patch #697613: don't exit the interpreter on a SystemExit
4556 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004557 variable is given, but break into the interactive interpreter just
4558 like on other exceptions or normal program exit.

4564 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004565
Georg Brandl0fca97a2007-03-05 22:28:08 +00004566- Patch #1674228: when assigning a slice (old-style), check for the
4567 sq_ass_slice instead of the sq_slice slot.
4568
Georg Brandl3ee81df2008-05-17 18:14:43 +00004569- When printing an unraisable error, don't print exceptions. before
4570 the name. This duplicates the behavior whening normally printing
4571 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004579- Bug #1377858: Fix the segfaulting of the interpreter when an object
4580 created a weakref on itself during a __del__ call for new-style
4581 classes (classic classes still have the bug).

5180 Python would crash instead of raising an error.
5181

5194
Georg Brandl3ee81df2008-05-17 18:14:43 +00005195- unittest now verifies more of its assumptions. In particular,
5196 TestCase and TestSuite subclasses (not instances) are no longer
5197 accepted in TestSuite.addTest(). This should cause no
5198 incompatibility since it never made sense with ordinary subclasses
5199 -- the failure just occurred later, with a more cumbersome
5200 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005481- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5482 with RFC 3207 and forgets any knowledge obtained from the server not
5483 obtained from the TLS negotiation itself. Patch contributed by Bill
5484 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005485
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005487 that the SMTP.starttls() caller no longer needs to call ehlo()
5488 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005489 does not claim to support starttls. Adds the
5490 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5571 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5572 silently miscode subclasses of those types. Now, it raises a
5573 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005574

Georg Brandl3ee81df2008-05-17 18:14:43 +00005589 time so that opening a database previously created with the DB_DUP
5590 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5591 opens. Specifically: dictionary assignment to a DB object will
5592 replace all values for a given key when the database allows
5593 duplicate values. DB users should use DB.put(k, v) when they want
5594 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005595

5601 characters with ASCII value less than 32. Also, it correctly quotes
5602 dots only if they occur on a single line, as opposed to the previous
5603 behavior of quoting dots if they are the second character of any
5604 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005605

5927-----
5928
Georg Brandl3ee81df2008-05-17 18:14:43 +00005929- Unified naming convention for free lists and their limits. All free
5930 lists in Object/ are named ``free_list``, the counter ``numfree``
5931 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5932 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005933
Georg Brandl3ee81df2008-05-17 18:14:43 +00005934- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5935 to ``PyTuple_SetItem``, it can be used to populate a brand new
5936 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005937
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005938- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005940- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5941 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5942 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005943
5944- Patch #1720595: add T_BOOL to the range of structmember types.
5945
5946- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5947 ``PyFloat_GetInfo()`` to the float API.
5948
Georg Brandl3ee81df2008-05-17 18:14:43 +00005949- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5950 of w# format code incorrectly truncated the length to an int, even
5951 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5952 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005953
Georg Brandl3ee81df2008-05-17 18:14:43 +00005954- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5955 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005957- PEP 3123: Provide forward compatibility with Python 3.0, while
5958 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5959 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005960
Georg Brandl3ee81df2008-05-17 18:14:43 +00005961- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5962 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005963
5964- Patch #1733960: Allow T_LONGLONG to accept ints.
5965
5966- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5967
Christian Heimes000a0742008-01-03 22:16:32 +00005968- Added a new API function ``PyImport_ImportModuleNoBlock``.

5971
5972- Fix some leftovers from the conversion from int to Py_ssize_t
5973 (relevant to strings and sequences of more than 2**31 items).
5974
5975- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5976 outside of pystate.c and should not be necessary.
5977
Georg Brandl3ee81df2008-05-17 18:14:43 +00005978- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5979 absolute imports. In earlier versions they might have used relative
5980 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005981
Georg Brandl3ee81df2008-05-17 18:14:43 +00005982- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5983 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005984
Georg Brandl3ee81df2008-05-17 18:14:43 +00005985- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005992- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5993 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5994 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5995 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005996
Georg Brandl3ee81df2008-05-17 18:14:43 +00005997- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00006008- buildtools now raises a DeprecationWarning.
6009
Georg Brandl3ee81df2008-05-17 18:14:43 +00006010- Removed the macfs module. It had been deprecated since Python 2.5.
6011 This lead to the deprecation of macostools.touched() as it relied
6012 solely on macfs and was a no-op under OS X.
