138 some values large enough to cause overflow, and (4) a number of
139 flaws that could lead to incorrectly rounded results.

158 in XML processing instructions and comments. These raw characters are
159 allowed by the XML specification, and are necessary when outputting e.g.
160 PHP code in a processing instruction. Patch by Neil Muller.

169 specified, rather than fall through to AF_PACKET (in the `socket` module).
170 Also, raise ValueError rather than TypeError when an unknown TIPC address
171 type is specified. Patch by Brian Curtin.

176 file position when calling `truncate()`. It would previously change the
177 file position to the given argument, which goes against the tradition of
178 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

183 :class:`zipfile.ZipExtFile` class used to represent files stored inside
184 an archive. The new implementation is significantly faster and can

186 It also solves an issue where interleaved calls to `read()` and
187 `readline()` give wrong results. Patch by Nir Aides.

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000196- Issue #7748: Since unicode values are supported for some metadata options
197 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
198 encoded string for them. This ensure that the upload and register commands
199 send the right values to PyPI without any error.
200
R. David Murrayed44dfa2010-01-16 05:15:17 +0000201- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Benjamin Petersonecdae192010-01-04 00:43:01 +0000279- The __complex__ method is now looked up on the class of instances to make it
280 consistent with other special methods.
281
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000282- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
283 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
284
Mark Dickinson1b34d252010-01-01 17:27:30 +0000285- Issue #5080: A number of functions and methods previously produced a
286 DeprecationWarning when passed a float argument where an integer was
287 expected. These functions and methods now raise TypeError instead.
288 The majority of the effects of this change are in the extension
289 modules, but some core functions and methods are affected: notably
290 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
291 methods.
292
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000293- Issue #7604: Deleting an unset slotted attribute did not raise an
294 AttributeError.

298 described in C99 Annex F.
299
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000300- Issue #7579: the msvcrt module now has docstrings for all its functions.
301
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000302- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
303 used to drop the time part of the result.
304
Mark Dickinson46572832009-12-27 14:55:57 +0000305- Issue #1811: improve accuracy and cross-platform consistency for
306 true division of integers: the result of a/b is now correctly
307 rounded for ints a and b (at least on IEEE 754 platforms), and in
308 particular does not depend on the internal representation of a long.
309
Ezio Melottif84caf42009-12-24 22:25:17 +0000310- Issue #6108: unicode(exception) and str(exception) should return the same

312
Ronald Oussoren92919a62009-12-24 13:30:58 +0000313- Issue #6834: replace the implementation for the 'python' and 'pythonw'
314 executables on OSX.
315

475
Mark Dickinsonb678de82009-11-19 18:41:49 +0000476- Issue #7117: repr(x) for a float x returns a result based on the
477 shortest decimal string that's guaranteed to round back to x under
478 correct rounding (with round-half-to-even rounding mode).
479 Previously it gave a string based on rounding x to 17 decimal digits.
480 repr(x) for a complex number behaves similarly. On platforms where
481 the correctly-rounded strtod and dtoa code is not supported (see below),
482 repr is unchanged.
483
484- Issue #7117: On almost all platforms: float-to-string and
485 string-to-float conversions within Python are now correctly rounded.
486 Places these conversions occur include: str for floats and complex
487 numbers; the float and complex constructors; old-style and new-style
488 numeric formatting; serialization and deserialization of floats and
489 complex numbers using marshal, pickle and json; parsing of float and
490 imaginary literals in Python code; Decimal-to-float conversion.
491
492 The conversions use a Python-adapted version of David Gay's
493 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
494 functions. This code is supported on Windows, and on Unix-like
495 platforms using gcc, icc or suncc as the C compiler. There may be a
496 small number of platforms on which correct operation of this code
497 cannot be guaranteed, so the code is not used: notably, this applies
498 to platforms where the C double format is not IEEE 754 binary64, and
499 to platforms on x86 hardware where the x87 FPU is set to 64-bit
500 precision and Python's configure script is unable to determine how
501 to change the FPU precision. On these platforms conversions use the
502 platform strtod and dtoa, as before.
503
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000504- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000505 now uses the correctly-rounded string <-> float conversions
506 described above (when available), and so produces correctly rounded
507 results that will display nicely under the float repr. There are
508 two related small changes: (1) round now accepts any class with an
509 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000510 floats for the second argument), and (2) an excessively large second
511 integer argument (e.g., round(1.234, 10**100)) no longer raises an
512 exception.

617
Raymond Hettinger62641e92009-06-23 20:59:43 +0000618- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
619 because it wasn't recognized as a sequence).
620
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000621- Issue #6289: Encoding errors from compile() were being masked.
622
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000623- When no module is given in a relative import, the module field of the
624 ImportFrom AST node is now None instead of an empty string.
625
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000626- Assignment to None using import statements now raises a SyntaxError.
627
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000628- Issue #4547: When debugging a very large function, it was not always
629 possible to update the lineno attribute of the current frame.
630
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000631- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000632 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000633
Raymond Hettinger578a2282009-05-29 04:58:52 +0000634- Issue #5982: staticmethod and classmethod now expose the wrapped
635 function with __func__.
636
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000637- Added support for multiple context managers in the same with-statement.
638 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +0000639
Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000640- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
641 statement and correctly lookup the __enter__ and __exit__ special methods.
642
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000643- Issue #5829: complex("1e500") no longer raises OverflowError. This
644 makes it consistent with float("1e500") and interpretation of real
645 and imaginary literals.
646
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000647- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
648
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000649- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
650 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000651
R. David Murray525cffc2009-05-13 13:07:14 +0000652- Issue #5994: the marshal module now has docstrings.
653
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000654- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
655 (1) inf and nan strings with trailing whitespace were incorrectly
656 rejected; (2) parsing of strings representing infinities and nans
657 was locale aware; and (3) the interpretation of fromhex('-nan')
658 didn't match that of float('-nan').
659
Eric Smitha985a3a2009-05-05 18:26:08 +0000660- Issue #5920: For float.__format__, change the behavior with the
661 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
662 to be like 'g' but with at least one decimal point and with a
663 default precision of 12. Previously, the behavior the same but with
664 a default precision of 6. This more closely matches str(), and
665 reduces surprises when adding alignment flags to the empty
666 presentation type. This also affects the new complex.__format__ in
667 the same way.
668
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000669- Issue #5890: in subclasses of 'property' the __doc__ attribute was
670 shadowed by classtype's, even if it was None. property now
671 inserts the __doc__ into the subclass instance __dict__.
672
Antoine Pitrou653dece2009-05-04 18:32:32 +0000673- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
674 sequences. Patch by Nick Barnes and Victor Stinner.
675
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000676- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000677 format(complex(1, 2./3), '.5') now produces a sensible result.
678

680 never gives more than the requested number of significant digits.
681
Eric Smithcac7af62009-04-27 19:04:37 +0000682- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

686 titlecase, but not their own uppercase.
687
Eric Smith068f0652009-04-25 21:40:15 +0000688- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
689 _PyOS_double_to_string or PyOS_double_to_string.
690
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000691- Issue #5283: Setting __class__ in __del__ caused a segfault.
692
Mark Dickinson95bc9802009-04-24 12:46:53 +0000693- Issue #5816: complex(repr(z)) now recovers z exactly, even when
694 z involves nans, infs or negative zeros.
695
Eric Smithaca19e62009-04-22 13:29:05 +0000696- Implement PEP 378, Format Specifier for Thousands Separator, for
697 floats, ints, and longs.
698
699- Issue #5515: 'n' formatting for ints, longs, and floats handles
700 leading zero formatting poorly.
701
702- Issue #5772: For float.__format__, don't add a trailing ".0" if
703 we're using no type code and we have an exponent.
704
Mark Dickinson6736cf82009-04-20 21:13:33 +0000705- Issue #3166: Make long -> float (and int -> float) conversions
706 correctly rounded.
707
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000708- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
709 some builtin types.
710
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000711- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000712 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000713
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000714- Issue #5759: float() didn't call __float__ on str subclasses.
715
Georg Brandl3c4a5462009-04-12 12:08:12 +0000716- Issue #5704: the "-3" command-line option now implies "-t".
717
R. David Murray0374a822009-04-09 21:54:50 +0000718- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
719 its clarity and its speed.
720
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000721- Issue #2396: the memoryview object was backported from Python 3.1.
722

727
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000728- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
729 the end sys.path, for compatibility with the system install of Python.
730
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000731- Issue #4688: Add a heuristic so that tuples and dicts containing only
732 untrackable objects are not tracked by the garbage collector. This can
733 reduce the size of collections and therefore the garbage collection overhead
734 on long-running programs, depending on their particular use of datatypes.
735
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000736- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
737 improve its performance. Long divisions and remainder operations
738 are now between 50% and 150% faster.
739
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000740- Issue #4258: Make it possible to use base 2**30 instead of base
741 2**15 for the internal representation of integers, for performance
742 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
743 --enable-big-digits option to configure, which overrides the
744 default. Add sys.long_info structseq to provide information about
745 the internal format.
746
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000747- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
748 result traceback.__members__ no longer exists.)
749
Mark Dickinson6b265f12009-03-18 16:07:26 +0000750- Issue #4474: PyUnicode_FromWideChar now converts characters outside
751 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
752 and sizeof(Py_UNICODE) == 2.
753
Eric Smith6f42edb2009-03-14 11:57:26 +0000754- Issue #5237: Allow auto-numbered fields in str.format(). For
755 example: '{} {}'.format(1, 2) == '1 2'.
756
Brett Cannon6c4cff02009-03-11 04:51:06 +0000757- Issue #3652: Make the 'line' argument for warnings.showwarning() a
758 requirement. Means the DeprecationWarning from Python 2.6 can go away.
759
Eric Smithe9fb6862009-02-20 14:02:36 +0000760- Issue #5247: Improve error message when unknown format codes are
761 used when using str.format() with str, unicode, long, int, and
762 float arguments.
763
Raymond Hettinger08259e82009-02-18 23:10:19 +0000764- Running Python with the -3 option now also warns about classic division
765 for ints and longs.
766
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000767- Issue #5260: Long integers now consume less memory: average
768 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
769 on a 64-bit system.
770
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000771- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
772 rotating the object pointer by 4 bits to the right.
773
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000774- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
775 it now forces its argument to double before testing for infinity.
776
Benjamin Petersone18ef192009-01-20 14:21:16 +0000777- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
778
Georg Brandl29c6a282009-04-05 20:23:13 +0000779- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000780 were suppressing all exceptions. These include list(), filter(), map(),
781 zip(), and bytearray().
782
Benjamin Peterson596d3062009-01-19 15:42:23 +0000783- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
784 functions.
785
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000786- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

790
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000791- Issue #4935: The overflow checking code in the expandtabs() method common
792 to str, bytes and bytearray could be optimized away by the compiler, letting
793 the interpreter segfault instead of raising an error.
794
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000795- Issue #3720: Fix a crash when an iterator modifies its class and removes its

801
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000802- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
803 collecting the oldest generation) so that allocating lots of objects without
804 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000805 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000806 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

809
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000810- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
811 an existing .py counterpart, override the co_filename attributes of all
812 code objects if the original filename is obsolete (which can happen if the
813 file has been renamed, moved, or if it is accessed through different paths).
814 Patch by Ziga Seilnacht and Jean-Paul Calderone.
815
Martin v. Löwis5344c992009-01-02 20:32:55 +0000816- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000818- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
819 file with `str' filename on Windows.
820
Antoine Pitrouaa687902009-01-01 14:11:22 +0000821- Issue #3680: Reference cycles created through a dict, set or deque iterator
822 did not get collected.
823
Nick Coghlan180e4002008-12-30 01:18:48 +0000824- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
825 where the tp_hash and tp_dict slots are both NULL.
826
Benjamin Peterson7af65562008-12-29 17:56:58 +0000827- Issue #4764: With io.open, IOError.filename is set when trying to open a
828 directory on POSIX systems.
829
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000830- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

834 bytearray.translate(). It was always allowed for bytes.translate().
835
Skip Montanarof205c132008-12-23 03:30:15 +0000836- Added test case to ensure attempts to read from a file opened for writing
837 fail.
838
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000839- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
840 print elapsed times, not only when some objects are uncollectable /
841 unreachable. Original patch by Neil Schemenauer.
842
Mark Dickinson1a707982008-12-17 16:14:37 +0000843- Issue #3439: Add a bit_length method to int and long.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000848- Issue #4597: Fixed exception handling when the __exit__ function of a
849 context manager returns a value that cannot be converted to a bool.
850
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000851- Issue #4597: Fixed several opcodes that weren't always propagating
852 exceptions.
853
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000854- Issue #4445: Replace "sizeof(PyStringObject)" with
855 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
856 str instances. On a typical machine this saves 3 bytes of memory
857 (on average) per string allocation.
858
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000859- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
860 interpreter to abort ("Fatal Python error: Could not reset the stack!")
861 instead of throwing a MemoryError.
862
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000863- Issue #3689: The list reversed iterator now supports __length_hint__
864 instead of __len__. Behavior now matches other reversed iterators.
865
Benjamin Petersonc078f922008-11-21 22:27:24 +0000866- Issue #4367: Python would segfault during compiling when the unicodedata
867 module couldn't be imported and \N escapes were present.
868
Vinay Sajip213faca2008-12-03 23:22:58 +0000869- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000870 method on file objects with closefd=False. The file descriptor is still
871 kept open but the file object behaves like a closed file. The ``FileIO``
872 object also got a new readonly attribute ``closefd``.
873
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000874- Issue #4348: Some bytearray methods returned that didn't cause any change to
875 the bytearray, returned the same bytearray instead of a copy.
876
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000877- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
878

880
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000881- Issue #4048: The parser module now correctly validates relative imports.
882
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000883- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
884 exec statement.
885
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000886- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
887 method does not return iterators for the 4th and 5th items.
888
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000889- Issue #4209: Enabling unicode_literals and the print_function in the same
890 __future__ import didn't work.
891
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000892- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000893 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000894
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000895- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
896 returned a path longer than MAX_PATH. (But It's doubtful this code path is
897 really executed because I cannot move to such directory on win2k)
898
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000899- Issue #4069: When set.remove(element) is used with a set element, the element
900 is temporarily replaced with an equivalent frozenset. But the eventual
901 KeyError would always report the empty frozenset([]) as the missing key. Now

2170 leak-chasing test runs give sensible results. The previous method of

2312
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002313- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2314
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002315- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2316 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2317 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2318 ``printf`` function, whereas PyString_FromFormat has an independent
2319 implementation and uses "%zd" on all platforms for size_t values.
2320 This makes a difference on win64, where ``printf`` needs "%Id" to display
2321 64bit values.
2322
Benjamin Peterson97179b02008-09-09 20:55:01 +00002323- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2324 error.
2325
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002326- Issue #3777: long() applied to a float object now always return a long
2327 object; previously an int would be returned for small values. the __long__
2328 method is allowed to return either an int or a long, but the behaviour of
2329 float objects should not change to respect backward compatibility.
2330
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002331- Issue #3751: str.rpartition would perform a left-partition when called with
2332 a unicode argument.
2333
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002334- Issue #3683: Fix compilation when --without-threads is given.
2335
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002336- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002337 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002338 was correctly parsed but parsing of subsequent arguments failed.
2339
Vinay Sajip35e3b032008-09-01 14:33:59 +00002340- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002341 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2342 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2343 when given a tuple of classes as second argument, were looking up
2344 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2345 type object.
2346
Neal Norwitz18aa3882008-08-24 05:04:52 +00002347- Fix crashes on memory allocation failure found with failmalloc.
2348
2349- Fix memory leaks found with valgrind and update suppressions file.
2350
2351- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Nick Coghland2e09382008-09-11 12:11:06 +00002389- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002390 return a list or None rather than a custom object.

2416 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2417 for catch_warnings() also led to an improvement in the raising of a
2418 DeprecationWarning related to warnings.warn_explicit().

2490-----------------
2491
Guido van Rossumf8402962008-08-20 15:01:50 +00002492- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2493 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2494 extensions do not automatically benefit from the class attribute
2495 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2496 to their tp_flags field if they care. This is a backwards
2497 compatibility feature; in 3.0, all types will use the cache by
2498 default.
2499
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002500- Keyword arguments can now follow starred arguments. (``f(a, *args,
2501 keyword=23)`` is now valid syntax.)
2502
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002503- ctypes function pointers that are COM methods have a boolean True
2504 value again.
2505
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002506- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2507 by denying s# to parse objects that have a releasebuffer procedure,
2508 and introducing s*.
2509
Georg Brandl1e13ea92008-08-11 09:07:59 +00002510- Issue #3537: Fix an assertion failure when an empty but presized dict
2511 object was stored in the freelist.
2512
Mark Dickinsonb6467572008-08-04 21:30:09 +00002513- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2514 ValueError consistently across platforms.
2515
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002516- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2517 (64bit Unix, for example), unichr() would truncate its argument and return
2518 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2519
Neal Norwitze7d8be82008-07-31 17:17:14 +00002520- Apply security patches from Apple.
2521
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002522- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2523 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2524
Antoine Pitrou92f82162008-07-25 22:22:08 +00002525- Issue #1819: function calls with several named parameters are now on
2526 average 35% faster (as measured by pybench).
2527
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002528- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2529 the python debugger steps into a class statement: the free variables (local
2530 variables defined in an outer scope) would be deleted from the outer scope.
2531
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002532- Issue #2620: Overflow checking when allocating or reallocating memory
2533 was not always being done properly in some python types and extension
2534 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2535 all been updated to perform better checks and places in the code that
2536 would previously leak memory on the error path when such an allocation
2537 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002542- Issue #3612: Added some missing basic types in ctypes.wintypes.
2543
Benjamin Petersone977ad42008-08-20 01:42:01 +00002544- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2545 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2546
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002547- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2548 version reported by these tools does not necessarily follow the python
2549 version numbering scheme, so the module is less strict when parsing it.
2550
Nick Coghlanf70385a2008-08-18 12:42:46 +00002551- Issue #2235: Added Py3k warnings for types which will become unhashable
2552 under the stricter __hash__ inheritance rules in 3.0. Several types
2553 which did not meet the rules for hash invariants and were already
2554 unhashable in 3.0 have now been explicitly flagged as unhashable in
2555 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2556 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2557
Brett Cannon88f801d2008-08-18 00:46:22 +00002558- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2559 imported into the module but exposed as part of the module's API.
2560

2671
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002672- Issue #643841: The language reference now provides more detailed

2684-----------------
2685
Georg Brandl3e483f62008-07-16 22:57:41 +00002686- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2687 its methods now allow for items objects that can be converted to
2688 an integer using operator.index().
2689
Mark Dickinson64b7e502008-07-16 09:40:03 +00002690- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2691 produced a ValueError instead of giving the correct float.
2692
Eric Smitha5fa5a22008-07-16 00:11:49 +00002693- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2694 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2695
Mark Dickinson7103aa42008-07-15 19:08:33 +00002696- Issue #3008: the float type has a new instance method 'float.hex'
2697 and a new class method 'float.fromhex' to convert floating-point
2698 numbers to and from hexadecimal strings, respectively.
2699
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002700- Issue #2235: __hash__ is once again inherited by default. To allow
2701 collections.Hashable to remain meaningful in the presence of the
2702 default hash implementation (object.__hash__), it is now possible
2703 to explicit block inheritance of hash by setting __hash__=None at
2704 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2705 level.
2706
Nick Coghlanb028f502008-07-13 14:52:36 +00002707- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2708 the parent module cannot be found while performing an absolute import.
2709 This means that an incorrectly defined __package__ attribute will
2710 now only prevent relative imports in that module rather than causing
2711 all imports from that module to fail.
2712
Nick Coghlan14ff9942008-07-08 14:21:42 +00002713- Issue #2517: Allow unicode messages in Exceptions again by correctly

2723 another thread's dictionary.
2724
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002725- Issue #3004: Minor change to slice.indices(): the start and stop
2726 arguments are now treated identically, making the behaviour easier
2727 to describe and understand. For example, slice(None, -10,
2728 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2729 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2730 10, -1).
2731
Georg Brandl278fc502008-07-19 12:46:12 +00002732- Issue #3219: Calling a function with repeated keyword arguments,
2733 f(a=2, a=23), would not cause a syntax error. This was a regression
2734 from 2.4 caused by the switch to the new compiler.

2773 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002774 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002775 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003182- On MacOS X it is now possible to install the framework in 64-bit
3183 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003184 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003185
3186 This is controlled by the configure argument ``--with-universal-archs``:
3187
3188 - ``--with-universal-archs=all``: install 4-way universal
3189
3190 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3191
3192 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3193
3194 This option should be used in combination with ``--enable-universalsdk=``.
3195
3196 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 +00003246- Issue #1631171: Re-implement the 'warnings' module in C (the
3247 original Python code has been kept as backup). This will allow for
3248 using the 'warning's machinery in such places as the parser where
3249 use of pure Python code is not possible. Both the ``showarning()``
3250 and ``formatwarning()`` gain an optional 'line' argument which is
3251 not called by default for backwards-compatibility reasons. Setting
3252 ``warnings.showwarning()`` to an implementation that lacks support
3253 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Issue #2550: The approach used by client/server code for obtaining
3317 ports to listen on in network-oriented tests has been refined in an
3318 effort to facilitate running multiple instances of the entire
3319 regression test suite in parallel without issue.
3320 test_support.bind_port() has been fixed such that it will always
3321 return a unique port -- which wasn't always the case with the
3322 previous implementation, especially if socket options had been set
3323 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3324 new implementation of bind_port() will actually raise an exception
3325 if it is passed an AF_INET/SOCK_STREAM socket with either the
3326 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3327 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3328 the socket it's been passed. This currently only applies to
3329 Windows. This option prevents any other sockets from binding to the
3330 host/port we've bound to, thus removing the possibility of the
3331 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3332 when a second SOCK_STREAM socket binds and accepts to a host/port
3333 that's already been bound by another socket. The optional preferred
3334 port parameter to bind_port() has been removed. Under no
3335 circumstances should tests be hard coding ports!
3336
3337 test_support.find_unused_port() has also been introduced, which will
3338 pass a temporary socket object to bind_port() in order to obtain an
3339 unused port. The temporary socket object is then closed and
3340 deleted, and the port is returned. This method should only be used
3341 for obtaining an unused port in order to pass to an external program
3342 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3343 a parameter to a server-oriented class that doesn't give you direct
3344 access to the underlying socket used.
3345
3346 Finally, test_support.HOST has been introduced, which should be used
3347 for the host argument of any relevant socket calls (i.e. bind and
3348 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003349
3350 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003351 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003352 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3353 test_asynchat and test_socket_ssl.
3354
Georg Brandl3ee81df2008-05-17 18:14:43 +00003355 It is now possible for multiple instances of the regression test
3356 suite to run in parallel without issue.

3409
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003410- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3412 Plane. This affected raw unicode literals and the
3413 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3414 this case, like normal unicode literals and the 'unicode-escape'
3415 codec.

3623-----------------
3624
Fred Drakea8ee94b2008-03-01 02:45:07 +00003625- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003626 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003631
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003632- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003633 issue 215555 for a discussion.
3634
Eric Smitha73fbe72008-02-23 03:09:44 +00003635- Added the future_builtins module, which contains hex() and oct().
3636 These are the PEP 3127 version of these functions, designed to be
3637 compatible with the hex() and oct() builtins from Python 3.0. They
3638 differ slightly in their output formats from the existing, unchanged
3639 Python 2.6 builtins. The expected usage of the future_builtins
3640 module is:
3641 from future_builtins import hex, oct
3642
Eric Smith7ef40bf2008-02-20 23:34:22 +00003643- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3644 exponents for exponents with absolute value < 100. Follows C99
3645 standard. This is a change on Windows, which would use 3 digits.
3646 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3647 so that any alterations it does to the resulting string will be
3648 available in stringlib/formatter.h (for float.__format__).
3649
Eric Smith5a3c1352008-02-19 13:21:56 +00003650- Implemented PEP 3101, Advanced String Formatting. This adds a new
3651 builtin format(); a format() method for str and unicode; a
3652 __format__() method to object, str, unicode, int, long, float, and
3653 datetime; the class string.Formatter; and the C API
3654 PyObject_Format().
3655
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656- Fixed several potential crashes, all caused by specially crafted
3657 __del__ methods exploiting objects in temporarily inconsistent
3658 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003659
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003660- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003661 prevent a possible crash: an Abstract Base Class would try to access
3662 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003663

Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Clear all free lists during a gc.collect() of the highest generation
3668 in order to allow pymalloc to free more arenas. Python may give back
3669 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003670
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Issue #2045: Fix an infinite recursion triggered when printing a
3672 subclass of collections.defaultdict, if its default_factory is set

Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3682 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003683 to compact the internal free lists of pre-allocted ints and floats.
3684
Georg Brandl3ee81df2008-05-17 18:14:43 +00003685- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3686 calls. Python expected the return type int but the fork familie
3687 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003688
Georg Brandl3ee81df2008-05-17 18:14:43 +00003689- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003701- Patch #1473257: generator objects gain a gi_code attribute. This is
3702 the same object as the func_code attribute of the function that
3703 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003704
Georg Brandl3ee81df2008-05-17 18:14:43 +00003705- Issue #1920: "while 0" statements were completely removed by the
3706 compiler, even in the presence of an "else" clause, which is
3707 supposed to be run when the condition is false. Now the compiler
3708 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003709
Guido van Rossumeead05f2008-01-24 18:21:02 +00003710- A few crashers fixed: weakref_in_del.py (issue #1377858);
3711 loosing_dict_ref.py (issue #1303614, test67.py);
3712 borrowed_ref_[34].py (not in tracker).
3713
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003714- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003715 suppressed while an extension is loaded by calling SetErrorMode in
3716 dynload_win.c. The error is still reported properly.
3717
Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003719 several extension methods and modules do not work without unicode
3720 support.
3721
Georg Brandl26543b12008-01-21 18:36:51 +00003722- Issue #1882: when compiling code from a string, encoding cookies in the

3724
Georg Brandl14404b62008-01-19 19:27:05 +00003725- Issue #1679: "0x" was taken as a valid integer literal.
3726
Georg Brandl6caad7d2008-01-26 14:19:22 +00003727- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003728 added.
3729
Christian Heimesc94e2b52008-01-14 04:13:37 +00003730- sys.float_info / PyFloat_GetInfo: The floating point information
3731 object was converted from a dict to a specialized structseq object.
3732
Georg Brandl3ee81df2008-05-17 18:14:43 +00003733- Patch #1816: Added sys.flags structseq. It exposes the status of
3734 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003735
Georg Brandl3ee81df2008-05-17 18:14:43 +00003736- Objects/structseq.c: Implemented new structseq representation. The
3737 patch makes structseqs (e.g. the return value of os.stat) more
3738 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003739
Georg Brandl3ee81df2008-05-17 18:14:43 +00003740- Patch #1700288: added a type attribute cache that caches method
3741 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003742
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003743- Bug #1776: __import__() no longer accepts filenames on any platform.
3744 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003745
Georg Brandlaed6c662008-01-07 17:25:53 +00003746- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3747

3749 envvar and sys.dont_write_bytecode attribute. All these can be set
3750 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003751
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Improve some exception messages when Windows fails to load an
3753 extension module. Now we get for example '%1 is not a valid Win32
3754 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003755

Christian Heimes0a8143f2007-12-18 23:22:54 +00003761- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003762 and INF. float("nan"), float("inf") and float("-inf") now work on
3763 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003764
Georg Brandl3ee81df2008-05-17 18:14:43 +00003765- Compiler now generates simpler and faster code for dictionary
3766 literals. The oparg for BUILD_MAP now indicates an estimated
3767 dictionary size. There is a new opcode, STORE_MAP, for adding
3768 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- Patch #1739468: Directories and zipfiles containing a __main__.py
3798 file can now be directly executed by passing their name to the
3799 interpreter. The directory/zipfile is automatically inserted as the
3800 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- Issue #1265: Fix a problem with sys.settrace, if the tracing
3803 function uses a generator expression when at the same time the
3804 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003805
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003806- sets and frozensets now have an isdisjoint() method.
3807

3811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- The enumerate() builtin function is no longer bounded to sequences
3813 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3814 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003815
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816- Issue #1686386: Tuple's tp_repr did not take into account the
3817 possibility of having a self-referential tuple, which is possible
3818 from C code. Nor did object's tp_str consider that a type's tp_str
3819 could do something that could lead to an inifinite recursion.
3820 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3821 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003822
Georg Brandl3ee81df2008-05-17 18:14:43 +00003823- Issue #1164: It was possible to trigger deadlock when using the
3824 'print' statement to write to a file since the GIL was not released
3825 as needed. Now PyObject_Print() does the right thing along with
3826 various tp_print implementations of the built-in types and those in
3827 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003828
Georg Brandl3ee81df2008-05-17 18:14:43 +00003829- Issue #1147: Exceptions were directly allowing string exceptions in

3831 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003832

Brett Cannon1e534b52007-09-07 04:18:30 +00003836- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837 PyObject_Call() never calling back out to Python code to trigger
3838 recursion depth updates/checks. Required the creation of a static
3839 RuntimeError instance in case normalizing an exception put the
3840 recursion check value past its limit. Fixes crashers
3841 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003842

Neal Norwitz0ac60192007-05-27 04:08:54 +00003856- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857 __*__ attributes. (Some already existed, e.g., __doc__ and
3858 __name__.)

3864 calls.
3865
Collin Winter62903052007-05-18 23:11:24 +00003866- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867 "except E as target:". This is to provide forwards compatibility
3868 with Python 3.0.

3874
Vinay Sajip8549ce32007-05-06 17:53:37 +00003875- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003876 setting a plain string, ie don't expand to single letter identifiers.
3877
Raymond Hettinger13936692007-04-11 18:40:58 +00003878- Request #1191699: Slices can now be pickled.
3879
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003880- Request #1193128: str.translate() now allows a None argument for

3882 remaining characters.
3883
Georg Brandl5cb76c12007-03-21 09:00:39 +00003884- Patch #1682205: a TypeError while unpacking an iterable is no longer
3885 masked by a generic one with the message "unpack non-sequence".
3886
Neal Norwitzaa754b72007-03-21 06:39:48 +00003887- Remove unused file Python/fmod.c.
3888
Guido van Rossum143b5642007-03-23 04:58:42 +00003889- Bug #1683368: The object.__init__() and object.__new__() methods are
3890 now stricter in rejecting excess arguments. The only time when
3891 either allows excess arguments is when it is not overridden and the
3892 other one is. For backwards compatibility, when both are
3893 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003894 warning later). Also, type.__init__() insists on the same signature
3895 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003897- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3898 object to complex using its __complex__() method before falling back
3899 to the __float__() method. Therefore, the functions in the cmath
3900 module now can operate on objects that define a __complex__()
3901 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003923 its argument, if it exists. If not, it will work like before. This
3924 allows customizing the output of dir() in the presence of a
3925 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003937- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003938 makes the filenames the warning module prints much more sensible
3939 when a PYTHONSTARTUP file is used.

Georg Brandl2c1375c2006-10-12 11:27:59 +00004007- Bug #1545497: when given an explicit base, int() did ignore NULs
4008 embedded in the string to convert.
4009
Georg Brandl846f73a2006-10-08 07:11:54 +00004010- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004058 generator expressions (x for x, in ... ) works again. Fixing this
4059 problem required changing the .pyc magic number. This means that
4060 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4868 with RFC 3207 and forgets any knowledge obtained from the server not
4869 obtained from the TLS negotiation itself. Patch contributed by Bill
4870 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004871
Georg Brandl3ee81df2008-05-17 18:14:43 +00004872- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004873 that the SMTP.starttls() caller no longer needs to call ehlo()
4874 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004875 does not claim to support starttls. Adds the
4876 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4957 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4958 silently miscode subclasses of those types. Now, it raises a
4959 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004960

Georg Brandl3ee81df2008-05-17 18:14:43 +00004975 time so that opening a database previously created with the DB_DUP
4976 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4977 opens. Specifically: dictionary assignment to a DB object will
4978 replace all values for a given key when the database allows
4979 duplicate values. DB users should use DB.put(k, v) when they want
4980 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004981

4987 characters with ASCII value less than 32. Also, it correctly quotes
4988 dots only if they occur on a single line, as opposed to the previous
4989 behavior of quoting dots if they are the second character of any
4990 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004991
