Florent Xiclunac2279652012-02-12 14:49:03 +0100377- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100378 has left two versions of customize_compiler, the original in
379 distutils.sysconfig and another copy in distutils.ccompiler, with some

382 is the case in 3.x.
383
Ned Deily0d0ea482012-02-10 12:59:06 +0100384- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
385 Distutils-based packages with C extension modules may fail because
386 Apple has removed gcc-4.2, the version used to build python.org
387 64-bit/32-bit Pythons. If the user does not explicitly override
388 the default C compiler by setting the CC environment variable,
389 Distutils will now attempt to compile extension modules with clang
390 if gcc-4.2 is required but not found. Also as a convenience, if
391 the user does explicitly set CC, substitute its value as the default
392 compiler in the Distutils LDSHARED configuration variable for OS X.
393 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
394 SDK, neither of which are available in Xcode 4. This change does not
395 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700668- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
669 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
670 interpreter process. This could cause failures in non-Distutils subprocesses
671 and was unreliable since tests or user programs could modify the interpreter
672 environment after Distutils set it. Instead, have Distutils set the the
673 deployment target only in the environment of each build subprocess. It is
674 still possible to globally override the default by setting
675 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
676 greater or equal to the default value, the value with which the interpreter
677 was built.

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

1502
Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001503- Issue #9869: Make long() and PyNumber_Long return something of type
1504 long for a class whose __long__ method returns a plain int. This

Antoine Pitrou0a7b65b2010-09-08 12:40:49 +00001510- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1511 thread-local storage key.
1512
Victor Stinnercaafd772010-09-08 10:51:01 +00001513- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1514 encoding and errors attributes instead of using utf-8 in strict mode, to get
1515 the same behaviour than the print statement.
1516
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00001517- Issue #9737: Fix a crash when trying to delete a slice or an item from

1530 output with no type specifier failed to match the str output:
1531
1532 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
1533 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
1534

1645 SSLSocket.sendto() to match the corresponding socket methods. Also,
1646 fix various SSLSocket methods to raise socket.error rather than an
1647 unhelpful TypeError when called on an unconnected socket. Original patch
1648 by Andrew Bennetts.
1649
Raymond Hettinger74f869e2010-09-13 22:14:36 +00001650- Issue #9826: OrderedDict.__repr__ can now handle self-referential
1651 values: d['x'] = d.
1652
Victor Stinner8fc843b2010-09-17 23:35:50 +00001653- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

Antoine Pitroue4195e82010-09-12 14:56:27 +00001655- Issue #9837: The read() method of ZipExtFile objects (as returned by

1657
Raymond Hettinger20397532010-09-12 02:11:45 +00001658- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1659 This prevents user-created self-referencing ordered dictionaries from
1660 becoming permanently uncollectable GC garbage. The downside is that
1661 removing __del__ means that the internal doubly-linked list has to wait for
1662 GC collection rather than freeing memory immediately when the refcnt drops
1663 to zero.
1664
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001665- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1668
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001669- Issue #9792: In case of connection failure, socket.create_connection()
1670 would swallow the exception and raise a new one, making it impossible
1671 to fetch the original errno, or to filter timeout errors. Now the
1672 original error is re-raised.
1673
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001674- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1675 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1676 be updated back after the system call. Original patch by Brian Brazil.
1677
Antoine Pitroudca9de92010-09-04 17:52:26 +00001678- Issue #1100562: Fix deep-copying of objects derived from the list and

1683
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001684- Issue #808164: Fixed socket.close to avoid references to globals, to
1685 avoid issues when socket.close is called from a __del__ method.
1686
Terry Reedyd2d2ae92010-11-11 23:22:19 +00001687- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

1689 heuristic. Patch by Terry Reedy and Eli Bendersky
1690
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00001691- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
1692 falling into recursion.
1693
R. David Murray7c4bf552010-08-25 01:45:57 +00001694- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1695 character years even if the message contains RFC822 two character years.
1696
Daniel Stutzbach91287322010-08-24 21:09:30 +00001697- Issue #8750: Fixed MutableSet's methods to correctly handle

1709 module now correctly return a set. (Patch by Eli Bendersky.)
1710
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001711- Issue #9617: Signals received during a low-level write operation aren't
1712 ignored by the buffered IO layer anymore.
1713
Benjamin Peterson52c36052010-08-21 03:03:22 +00001714- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
1715 are not held onto after they are deleted elsewhere.
1716
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001717- Issue #9626: the view methods for collections.OrderedDict() were returning
1718 the unordered versions inherited from dict. Those methods are now
1719 overridden to provide ordered views.
1720
Éric Araujo0389ae62010-08-14 03:07:46 +00001721- Issue #8688: MANIFEST files created by distutils now include a magic
1722 comment indicating they are generated. Manually maintained MANIFESTs
1723 without this marker will not be overwritten or removed.
1724
Antoine Pitroue1436d12010-08-12 15:25:51 +00001725- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1726 and a BadZipfile error is raised if it doesn't match (as used to be the
1727 case in Python 2.5 and earlier).
1728
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001729- Issue #9550: a BufferedReader could issue an additional read when the
1730 original read request had been satisfied, which could block indefinitely
1731 when the underlying raw IO channel was e.g. a socket. Report and original
1732 patch by Jason V. Miller.
1733
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001734- Issue #9551: Don't raise TypeError when setting the value to None for

1751
Senthil Kumarane677ecf2010-08-08 11:56:31 +00001752- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
1753 This is how it is supposed to work, wget and curl do the same. Previous
1754 behavior was wrong.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002122- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2123 start byte and the continuation byte(s) are now considered invalid, instead
2124 of the number of bytes specified by the start byte.
2125 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2126 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2127 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2128 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002136- Issue #8748: Fix two issues with comparisons between complex and integer
2137 objects. (1) The comparison could incorrectly return True in some cases
2138 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2139 (2) The comparison raised an OverflowError for large integers, leading
2140 to unpredictable exceptions when combining integers and complex objects
2141 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002143- Issue #5211: Implicit coercion for the complex type is now completely

2511 changed.

2524 with a non-empty format string. This is an effort to future-proof user
2525 code. If a derived class does not currently implement __format__ but later
2526 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002527 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002528 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002561- Issue #8257: The Decimal construct now accepts a float instance directly,
2562 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002563
2564 >>> Decimal(1.1)
2565 Decimal('1.100000000000000088817841970012523233890533447265625')
2566

Georg Brandlfee0f442010-05-22 21:26:21 +00002578- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2579 InvalidOperation instead of returning False. (Comparisons involving a quiet
2580 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2581 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002582
Georg Brandlfee0f442010-05-22 21:26:21 +00002583- Issue #2531: Comparison operations between floats and Decimal instances now
2584 return a result based on the numeric values of the operands; previously they
2585 returned an arbitrary result based on the relative ordering of id(float) and
2586 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002587
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002588- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002589 argument `-` which tells it to read files to compile from stdin. Each line is
2590 read on demand and the named file is compiled immediately. (Original patch by
2591 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002592
Georg Brandlfee0f442010-05-22 21:26:21 +00002593- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Georg Brandlfee0f442010-05-22 21:26:21 +00002600- Comparisons using one of <, <=, >, >= between a complex instance and a
2601 Fractions instance now raise TypeError instead of returning True/False. This
2602 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2603 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002659 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2660 log file to compute the next rollover time. If the log file does not exist,

Georg Brandlba83f822010-03-14 09:50:54 +00002671- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2672 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2673 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002702- Issue #8300: When passing a non-integer argument to struct.pack with any
2703 integer format code, struct.pack first attempts to convert the non-integer
2704 using its __index__ method. If that method is non-existent or raises
2705 TypeError it goes on to try the __int__ method, as described below.
2706
Georg Brandlba83f822010-03-14 09:50:54 +00002707- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2708 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2709 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002710 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2711 inconsistent: __int__ was used for some integer codes but not for others, and
2712 the set of integer codes for which it was used differed between native packing
2713 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003020- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003021 file position when calling `truncate()`. It would previously change the file
3022 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003023 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00003025- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3026 class used to represent files stored inside an archive. The new
3027 implementation is significantly faster and can be wrapped in a
3028 ``io.BufferedReader`` object for more speedups. It also solves an issue
3029 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003120- The ``__complex__()`` method is now looked up on the class of instances to
3121 make it consistent with other special methods.

3125
Mark Dickinson1b34d252010-01-01 17:27:30 +00003126- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003127 DeprecationWarning when passed a float argument where an integer was expected.
3128 These functions and methods now raise TypeError instead. The majority of the
3129 effects of this change are in the extension modules, but some core functions
3130 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3131 and many unicode/str methods.

3146 least on IEEE 754 platforms), and in particular does not depend on the
3147 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003296- Issue #3382: 'F' formatting for float and complex now convert the result to
3297 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3298 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003299
Georg Brandlba83f822010-03-14 09:50:54 +00003300- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3301 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003302
Georg Brandlba83f822010-03-14 09:50:54 +00003303- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3304 1e-100 used to raise OverflowError, but now gives the requested 120
3305 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00003306

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003313
Georg Brandlba83f822010-03-14 09:50:54 +00003314- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3315 decimal string that's guaranteed to round back to x under correct rounding
3316 (with round-half-to-even rounding mode). Previously it gave a string based on
3317 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3318 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3319 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003320
Georg Brandlba83f822010-03-14 09:50:54 +00003321- Issue #7117: On almost all platforms: float-to-string and string-to-float
3322 conversions within Python are now correctly rounded. Places these conversions
3323 occur include: str for floats and complex numbers; the float and complex
3324 constructors; old-style and new-style numeric formatting; serialization and
3325 deserialization of floats and complex numbers using marshal, pickle and json;
3326 parsing of float and imaginary literals in Python code; Decimal-to-float
3327 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003328
Georg Brandlba83f822010-03-14 09:50:54 +00003329 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3330 providing correctly-rounded strtod and dtoa C functions. This code is
3331 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3332 the C compiler. There may be a small number of platforms on which correct
3333 operation of this code cannot be guaranteed, so the code is not used: notably,
3334 this applies to platforms where the C double format is not IEEE 754 binary64,
3335 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3336 and Python's configure script is unable to determine how to change the FPU
3337 precision. On these platforms conversions use the platform strtod and dtoa,
3338 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003339
Georg Brandlba83f822010-03-14 09:50:54 +00003340- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3341 uses the correctly-rounded string <-> float conversions described above (when
3342 available), and so produces correctly rounded results that will display nicely
3343 under the float repr. There are two related small changes: (1) round now
3344 accepts any class with an ``__index__()`` method for its second argument (but
3345 no longer accepts floats for the second argument), and (2) an excessively
3346 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3347 raises an exception.

3350
Georg Brandlba83f822010-03-14 09:50:54 +00003351- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00003490 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3491 (2) parsing of strings representing infinities and nans was locale aware; and
3492 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003494- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3495 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3496 but with at least one decimal point and with a default precision
3497 of 12. Previously, the behavior the same but with a default precision of 6.
3498 This more closely matches ``str()``, and reduces surprises when adding
3499 alignment flags to the empty presentation type. This also affects the new
3500 complex.__format__ in the same way.
3501
3502- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3503 classtype's, even if it was None. property now inserts the __doc__ into the
3504 subclass instance __dict__.

3731 eventual KeyError would always report the empty ``frozenset()`` as the missing

Georg Brandlba83f822010-03-14 09:50:54 +00004986 leak-chasing test runs give sensible results. The previous method of reaping
4987 threads could return successfully while some Thread objects were still

5127
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005128- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5129
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005130- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5131 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5132 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5133 ``printf`` function, whereas PyString_FromFormat has an independent
5134 implementation and uses "%zd" on all platforms for size_t values.
5135 This makes a difference on win64, where ``printf`` needs "%Id" to display
5136 64bit values.
5137
Benjamin Peterson97179b02008-09-09 20:55:01 +00005138- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5139 error.
5140
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005141- Issue #3777: long() applied to a float object now always return a long
5142 object; previously an int would be returned for small values. the __long__
5143 method is allowed to return either an int or a long, but the behaviour of
5144 float objects should not change to respect backward compatibility.
5145
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005146- Issue #3751: str.rpartition would perform a left-partition when called with
5147 a unicode argument.
5148
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005149- Issue #3683: Fix compilation when --without-threads is given.
5150
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005151- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005152 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005153 was correctly parsed but parsing of subsequent arguments failed.
5154
Vinay Sajip35e3b032008-09-01 14:33:59 +00005155- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005156 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5157 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5158 when given a tuple of classes as second argument, were looking up
5159 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5160 type object.
5161
Neal Norwitz18aa3882008-08-24 05:04:52 +00005162- Fix crashes on memory allocation failure found with failmalloc.
5163
5164- Fix memory leaks found with valgrind and update suppressions file.
5165
5166- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5167
5168- Fix problem using wrong name in decimal module reported by pychecker.
5169
Christian Heimes7d4c3172008-08-22 19:47:25 +00005170- Silenced another compiler warning about a used but not defined
5171 function 'stringlib_contains_obj'.
5172
Benjamin Peterson712ee922008-08-24 18:10:20 +00005173- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5174 ``__delslice__``.
5175
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005176- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5177 library targets in the Makefile.
5178
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005179- Issue #1204: The configure script now tests for additional libraries
5180 that may be required when linking against readline. This fixes issues
5181 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00005231 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5232 for catch_warnings() also led to an improvement in the raising of a
5233 DeprecationWarning related to warnings.warn_explicit().
5234
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005235- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005299What's New in Python 2.6 beta 3?
5300================================
5301
Barry Warsaw07a4a382008-08-21 01:15:08 +00005302*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005303
5304Core and Builtins
5305-----------------
5306
Guido van Rossumf8402962008-08-20 15:01:50 +00005307- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5308 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5309 extensions do not automatically benefit from the class attribute
5310 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5311 to their tp_flags field if they care. This is a backwards
5312 compatibility feature; in 3.0, all types will use the cache by
5313 default.
5314
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005315- Keyword arguments can now follow starred arguments. (``f(a, *args,
5316 keyword=23)`` is now valid syntax.)
5317
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005318- ctypes function pointers that are COM methods have a boolean True
5319 value again.
5320
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005321- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5322 by denying s# to parse objects that have a releasebuffer procedure,
5323 and introducing s*.
5324
Georg Brandl1e13ea92008-08-11 09:07:59 +00005325- Issue #3537: Fix an assertion failure when an empty but presized dict
5326 object was stored in the freelist.
5327
Mark Dickinsonb6467572008-08-04 21:30:09 +00005328- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5329 ValueError consistently across platforms.
5330
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005331- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5332 (64bit Unix, for example), unichr() would truncate its argument and return
5333 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5334
Neal Norwitze7d8be82008-07-31 17:17:14 +00005335- Apply security patches from Apple.
5336
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005337- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5338 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5339
Antoine Pitrou92f82162008-07-25 22:22:08 +00005340- Issue #1819: function calls with several named parameters are now on
5341 average 35% faster (as measured by pybench).
5342
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005343- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5344 the python debugger steps into a class statement: the free variables (local
5345 variables defined in an outer scope) would be deleted from the outer scope.
5346
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005347- Issue #2620: Overflow checking when allocating or reallocating memory
5348 was not always being done properly in some python types and extension
5349 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5350 all been updated to perform better checks and places in the code that
5351 would previously leak memory on the error path when such an allocation
5352 failed have been fixed.

5360 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5361
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005362- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5363 version reported by these tools does not necessarily follow the python
5364 version numbering scheme, so the module is less strict when parsing it.
5365
Nick Coghlanf70385a2008-08-18 12:42:46 +00005366- Issue #2235: Added Py3k warnings for types which will become unhashable
5367 under the stricter __hash__ inheritance rules in 3.0. Several types
5368 which did not meet the rules for hash invariants and were already
5369 unhashable in 3.0 have now been explicitly flagged as unhashable in
5370 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5371 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5372
Brett Cannon88f801d2008-08-18 00:46:22 +00005373- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5374 imported into the module but exposed as part of the module's API.
5375

5381
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005382- Issue #3575: Incremental decoder's decode function now takes bytearray
5383 by using 's*' instead of 't#'.
5384
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005385- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005386 fails unicode conversion on 2nd parameter. (windows only)
5387
Georg Brandl222e2082010-08-01 22:27:39 +00005388- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005389 in a redirect.
5390

5420 to _sre.compile() will now be rejected. This should not affect anybody
5421 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00005442 asking for a specific length. This problem only affected files opened

5469 file name rather than a ZipInfo instance, so files are extracted with
5470 mode 0600 rather than 000 under Unix.
5471
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005472- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

5485 interaction with the tp_hash slot (added in 2.6b2) are now documented
5486
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005487- Issue #643841: The language reference now provides more detailed

5499-----------------
5500
Georg Brandl3e483f62008-07-16 22:57:41 +00005501- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5502 its methods now allow for items objects that can be converted to
5503 an integer using operator.index().
5504
Mark Dickinson64b7e502008-07-16 09:40:03 +00005505- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5506 produced a ValueError instead of giving the correct float.
5507
Eric Smitha5fa5a22008-07-16 00:11:49 +00005508- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5509 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5510
Mark Dickinson7103aa42008-07-15 19:08:33 +00005511- Issue #3008: the float type has a new instance method 'float.hex'
5512 and a new class method 'float.fromhex' to convert floating-point
5513 numbers to and from hexadecimal strings, respectively.
5514
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005515- Issue #2235: __hash__ is once again inherited by default. To allow
5516 collections.Hashable to remain meaningful in the presence of the
5517 default hash implementation (object.__hash__), it is now possible
5518 to explicit block inheritance of hash by setting __hash__=None at
5519 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5520 level.
5521
Nick Coghlanb028f502008-07-13 14:52:36 +00005522- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5523 the parent module cannot be found while performing an absolute import.
5524 This means that an incorrectly defined __package__ attribute will
5525 now only prevent relative imports in that module rather than causing
5526 all imports from that module to fail.
5527
Nick Coghlan14ff9942008-07-08 14:21:42 +00005528- Issue #2517: Allow unicode messages in Exceptions again by correctly

5538 another thread's dictionary.
5539
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005540- Issue #3004: Minor change to slice.indices(): the start and stop
5541 arguments are now treated identically, making the behaviour easier
5542 to describe and understand. For example, slice(None, -10,
5543 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5544 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5545 10, -1).
5546
Georg Brandl278fc502008-07-19 12:46:12 +00005547- Issue #3219: Calling a function with repeated keyword arguments,
5548 f(a=2, a=23), would not cause a syntax error. This was a regression
5549 from 2.4 caused by the switch to the new compiler.

5559 api functions without holding the GIL, which could lead to a fatal
5560 error when they failed.
5561
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005562- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005587- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5588 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005589 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005590 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005606- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5996
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005997- On MacOS X it is now possible to install the framework in 64-bit
5998 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005999 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006000
6001 This is controlled by the configure argument ``--with-universal-archs``:
6002
6003 - ``--with-universal-archs=all``: install 4-way universal
6004
6005 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6006
6007 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6008
6009 This option should be used in combination with ``--enable-universalsdk=``.
6010
6011 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 +00006061- Issue #1631171: Re-implement the 'warnings' module in C (the
6062 original Python code has been kept as backup). This will allow for
6063 using the 'warning's machinery in such places as the parser where
6064 use of pure Python code is not possible. Both the ``showarning()``
6065 and ``formatwarning()`` gain an optional 'line' argument which is
6066 not called by default for backwards-compatibility reasons. Setting
6067 ``warnings.showwarning()`` to an implementation that lacks support
6068 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006110- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006111 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006131- Issue #2550: The approach used by client/server code for obtaining
6132 ports to listen on in network-oriented tests has been refined in an
6133 effort to facilitate running multiple instances of the entire
6134 regression test suite in parallel without issue.
6135 test_support.bind_port() has been fixed such that it will always
6136 return a unique port -- which wasn't always the case with the
6137 previous implementation, especially if socket options had been set
6138 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6139 new implementation of bind_port() will actually raise an exception
6140 if it is passed an AF_INET/SOCK_STREAM socket with either the
6141 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6142 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6143 the socket it's been passed. This currently only applies to
6144 Windows. This option prevents any other sockets from binding to the
6145 host/port we've bound to, thus removing the possibility of the
6146 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6147 when a second SOCK_STREAM socket binds and accepts to a host/port
6148 that's already been bound by another socket. The optional preferred
6149 port parameter to bind_port() has been removed. Under no
6150 circumstances should tests be hard coding ports!
6151
6152 test_support.find_unused_port() has also been introduced, which will
6153 pass a temporary socket object to bind_port() in order to obtain an
6154 unused port. The temporary socket object is then closed and
6155 deleted, and the port is returned. This method should only be used
6156 for obtaining an unused port in order to pass to an external program
6157 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6158 a parameter to a server-oriented class that doesn't give you direct
6159 access to the underlying socket used.
6160
6161 Finally, test_support.HOST has been introduced, which should be used
6162 for the host argument of any relevant socket calls (i.e. bind and
6163 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006164
6165 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006166 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006167 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6168 test_asynchat and test_socket_ssl.
6169
Georg Brandl3ee81df2008-05-17 18:14:43 +00006170 It is now possible for multiple instances of the regression test
6171 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006450- Added the future_builtins module, which contains hex() and oct().
6451 These are the PEP 3127 version of these functions, designed to be
6452 compatible with the hex() and oct() builtins from Python 3.0. They
6453 differ slightly in their output formats from the existing, unchanged
6454 Python 2.6 builtins. The expected usage of the future_builtins
6455 module is:
6456 from future_builtins import hex, oct
6457
Eric Smith7ef40bf2008-02-20 23:34:22 +00006458- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6459 exponents for exponents with absolute value < 100. Follows C99
6460 standard. This is a change on Windows, which would use 3 digits.
6461 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6462 so that any alterations it does to the resulting string will be
6463 available in stringlib/formatter.h (for float.__format__).
6464
Eric Smith5a3c1352008-02-19 13:21:56 +00006465- Implemented PEP 3101, Advanced String Formatting. This adds a new
6466 builtin format(); a format() method for str and unicode; a
6467 __format__() method to object, str, unicode, int, long, float, and
6468 datetime; the class string.Formatter; and the C API
6469 PyObject_Format().
6470
Georg Brandl3ee81df2008-05-17 18:14:43 +00006471- Fixed several potential crashes, all caused by specially crafted
6472 __del__ methods exploiting objects in temporarily inconsistent
6473 state.

6477 a slot on a registered virtual subclass.

6480 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006481
Georg Brandl3ee81df2008-05-17 18:14:43 +00006482- Clear all free lists during a gc.collect() of the highest generation
6483 in order to allow pymalloc to free more arenas. Python may give back
6484 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006485
Georg Brandl3ee81df2008-05-17 18:14:43 +00006486- Issue #2045: Fix an infinite recursion triggered when printing a
6487 subclass of collections.defaultdict, if its default_factory is set
6488 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006489
Christian Heimesf75dbef2008-02-08 00:11:31 +00006490- Fixed a minor memory leak in dictobject.c. The content of the free
6491 list was not freed on interpreter shutdown.
6492
Georg Brandl21e99f42010-03-07 15:23:59 +00006493- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006494 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006495
Georg Brandl3ee81df2008-05-17 18:14:43 +00006496- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6497 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006498 to compact the internal free lists of pre-allocted ints and floats.
6499
Georg Brandl3ee81df2008-05-17 18:14:43 +00006500- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6501 calls. Python expected the return type int but the fork familie
6502 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006503
Georg Brandl3ee81df2008-05-17 18:14:43 +00006504- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6505 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006506
Georg Brandl3ee81df2008-05-17 18:14:43 +00006507- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6508 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006509
Georg Brandl3ee81df2008-05-17 18:14:43 +00006510- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6511 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00006513- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6514 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006515
Georg Brandl3ee81df2008-05-17 18:14:43 +00006516- Patch #1473257: generator objects gain a gi_code attribute. This is
6517 the same object as the func_code attribute of the function that
6518 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006519
Georg Brandl3ee81df2008-05-17 18:14:43 +00006520- Issue #1920: "while 0" statements were completely removed by the
6521 compiler, even in the presence of an "else" clause, which is
6522 supposed to be run when the condition is false. Now the compiler
6523 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006524
Guido van Rossumeead05f2008-01-24 18:21:02 +00006525- A few crashers fixed: weakref_in_del.py (issue #1377858);
6526 loosing_dict_ref.py (issue #1303614, test67.py);
6527 borrowed_ref_[34].py (not in tracker).
6528
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006529- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006530 suppressed while an extension is loaded by calling SetErrorMode in
6531 dynload_win.c. The error is still reported properly.
6532
Georg Brandl3ee81df2008-05-17 18:14:43 +00006533- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006534 several extension methods and modules do not work without unicode
6535 support.
6536
Georg Brandl26543b12008-01-21 18:36:51 +00006537- Issue #1882: when compiling code from a string, encoding cookies in the
6538 second line of code were not always recognized correctly.
6539
Georg Brandl14404b62008-01-19 19:27:05 +00006540- Issue #1679: "0x" was taken as a valid integer literal.
6541
Georg Brandl6caad7d2008-01-26 14:19:22 +00006542- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006543 added.
6544
Christian Heimesc94e2b52008-01-14 04:13:37 +00006545- sys.float_info / PyFloat_GetInfo: The floating point information
6546 object was converted from a dict to a specialized structseq object.
6547
Georg Brandl3ee81df2008-05-17 18:14:43 +00006548- Patch #1816: Added sys.flags structseq. It exposes the status of
6549 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006550
Georg Brandl3ee81df2008-05-17 18:14:43 +00006551- Objects/structseq.c: Implemented new structseq representation. The
6552 patch makes structseqs (e.g. the return value of os.stat) more
6553 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006554
Georg Brandl3ee81df2008-05-17 18:14:43 +00006555- Patch #1700288: added a type attribute cache that caches method
6556 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006557
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006558- Bug #1776: __import__() no longer accepts filenames on any platform.
6559 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006560
Georg Brandlaed6c662008-01-07 17:25:53 +00006561- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6562
Georg Brandl3ee81df2008-05-17 18:14:43 +00006563- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6564 envvar and sys.dont_write_bytecode attribute. All these can be set
6565 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006566
Georg Brandl3ee81df2008-05-17 18:14:43 +00006567- Improve some exception messages when Windows fails to load an
6568 extension module. Now we get for example '%1 is not a valid Win32
6569 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006570

6574 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006575
Christian Heimes0a8143f2007-12-18 23:22:54 +00006576- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006577 and INF. float("nan"), float("inf") and float("-inf") now work on
6578 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Compiler now generates simpler and faster code for dictionary
6581 literals. The oparg for BUILD_MAP now indicates an estimated
6582 dictionary size. There is a new opcode, STORE_MAP, for adding
6583 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006612- Patch #1739468: Directories and zipfiles containing a __main__.py
6613 file can now be directly executed by passing their name to the
6614 interpreter. The directory/zipfile is automatically inserted as the
6615 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006616
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617- Issue #1265: Fix a problem with sys.settrace, if the tracing
6618 function uses a generator expression when at the same time the
6619 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006620
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006621- sets and frozensets now have an isdisjoint() method.
6622
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006623- optimize the performance of builtin.sum().
6624
Neal Norwitz44f326e2007-10-05 05:29:17 +00006625- Fix warnings found by the new version of the Coverity checker.
6626
Georg Brandl21e99f42010-03-07 15:23:59 +00006627- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006628 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6629 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006630
Georg Brandl3ee81df2008-05-17 18:14:43 +00006631- Issue #1686386: Tuple's tp_repr did not take into account the
6632 possibility of having a self-referential tuple, which is possible
6633 from C code. Nor did object's tp_str consider that a type's tp_str
6634 could do something that could lead to an inifinite recursion.
6635 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6636 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006637
Georg Brandl3ee81df2008-05-17 18:14:43 +00006638- Issue #1164: It was possible to trigger deadlock when using the
6639 'print' statement to write to a file since the GIL was not released
6640 as needed. Now PyObject_Print() does the right thing along with
6641 various tp_print implementations of the built-in types and those in
6642 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006643
Georg Brandl3ee81df2008-05-17 18:14:43 +00006644- Issue #1147: Exceptions were directly allowing string exceptions in
6645 their throw() method even though string exceptions no longer
6646 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006647
Georg Brandl3ee81df2008-05-17 18:14:43 +00006648- Issue #1096: Prevent a segfault from getting the repr of a very
6649 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006650
Brett Cannon1e534b52007-09-07 04:18:30 +00006651- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006652 PyObject_Call() never calling back out to Python code to trigger
6653 recursion depth updates/checks. Required the creation of a static
6654 RuntimeError instance in case normalizing an exception put the
6655 recursion check value past its limit. Fixes crashers
6656 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006657

Neal Norwitz0ac60192007-05-27 04:08:54 +00006671- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672 __*__ attributes. (Some already existed, e.g., __doc__ and
6673 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006674
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006675- Add -3 option to the interpreter to warn about features that are
6676 deprecated and will be changed/removed in Python 3.0.
6677
Georg Brandl2134e752007-05-21 20:34:16 +00006678- Patch #1686487: you can now pass any mapping after '**' in function
6679 calls.
6680
Collin Winter62903052007-05-18 23:11:24 +00006681- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006682 "except E as target:". This is to provide forwards compatibility
6683 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00006685- Deprecate BaseException.message as per PEP 352.
6686
Georg Brandl3ee81df2008-05-17 18:14:43 +00006687- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006688 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006690- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006691 setting a plain string, ie don't expand to single letter identifiers.
6692
Raymond Hettinger13936692007-04-11 18:40:58 +00006693- Request #1191699: Slices can now be pickled.
6694
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006695- Request #1193128: str.translate() now allows a None argument for
6696 translations that only remove characters without re-mapping the
6697 remaining characters.
6698
Georg Brandl5cb76c12007-03-21 09:00:39 +00006699- Patch #1682205: a TypeError while unpacking an iterable is no longer
6700 masked by a generic one with the message "unpack non-sequence".
6701
Neal Norwitzaa754b72007-03-21 06:39:48 +00006702- Remove unused file Python/fmod.c.
6703
Guido van Rossum143b5642007-03-23 04:58:42 +00006704- Bug #1683368: The object.__init__() and object.__new__() methods are
6705 now stricter in rejecting excess arguments. The only time when
6706 either allows excess arguments is when it is not overridden and the
6707 other one is. For backwards compatibility, when both are
6708 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006709 warning later). Also, type.__init__() insists on the same signature
6710 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006712- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6713 object to complex using its __complex__() method before falling back
6714 to the __float__() method. Therefore, the functions in the cmath
6715 module now can operate on objects that define a __complex__()

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007688 that the SMTP.starttls() caller no longer needs to call ehlo()
7689 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007690 does not claim to support starttls. Adds the
7691 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7692 Fenner.

7772 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7773 silently miscode subclasses of those types. Now, it raises a
7774 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007775

Georg Brandl3ee81df2008-05-17 18:14:43 +00007790 time so that opening a database previously created with the DB_DUP
7791 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7792 opens. Specifically: dictionary assignment to a DB object will
7793 replace all values for a given key when the database allows
7794 duplicate values. DB users should use DB.put(k, v) when they want
7795 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007796

7802 characters with ASCII value less than 32. Also, it correctly quotes
7803 dots only if they occur on a single line, as opposed to the previous
7804 behavior of quoting dots if they are the second character of any
7805 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007806
