1185
1186- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1187 and later systems as is currently done for Python 3.x installers.
1188 For 2.7.7 only, we will provide three installers:
1189 the legacy deprecated 10.3+ 32-bit-only format;
1190 the newer 10.5+ 32-bit-only format;
1191 and the unchanged 10.6+ 64-/32-bit format.
1192 Although binary installers will no longer be available from
1193 python.org as of 2.7.8, it will still be possible to build from
1194 source on 10.3.9 and 10.4 systems if necessary.
1195 See Mac/BuildScript/README.txt for more information.

2577 32-bit-only installer Pythons on systems with Xcode 4 (currently
2578 OS X 10.8, 10.7, and optionally 10.6).
2579 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2580 * Since Xcode 4 removes ppc support, extension module builds now
2581 check for ppc compiler support and by default remove ppc and
2582 ppc64 archs when they are not available.
2583 * Extension module builds now revert to using system installed
2584 headers and libs (/usr and /System/Library) if the SDK used
2585 to build the interpreter is not installed or has moved.
2586 * Try to avoid building extension modules with deprecated
2587 and problematic Apple llvm-gcc compiler. If original compiler
2588 is not available, use clang instead by default.

Ned Deilyc47a4592012-02-11 20:40:24 +01003026 has left two versions of customize_compiler, the original in
3027 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01003032- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3033 Distutils-based packages with C extension modules may fail because
3034 Apple has removed gcc-4.2, the version used to build python.org
3035 64-bit/32-bit Pythons. If the user does not explicitly override
3036 the default C compiler by setting the CC environment variable,
3037 Distutils will now attempt to compile extension modules with clang
3038 if gcc-4.2 is required but not found. Also as a convenience, if
3039 the user does explicitly set CC, substitute its value as the default
3040 compiler in the Distutils LDSHARED configuration variable for OS X.
3041 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3042 SDK, neither of which are available in Xcode 4. This change does not
3043 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003293- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3294 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3295 interpreter process. This could cause failures in non-Distutils subprocesses
3296 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003297 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003298 deployment target only in the environment of each build subprocess. It is
3299 still possible to globally override the default by setting
3300 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3301 greater or equal to the default value, the value with which the interpreter
3302 was built.

3331 updating the check interval, so if the user decreases the check interval,
3332 the ticker doesn't have to wind down to zero from the old starting point
3333 before the new interval takes effect. And if the user increases the
3334 interval, it makes sure the new limit takes effect right away rather have an
3335 early task switch before recognizing the new interval.

4185 thread-local storage key.
4186
Victor Stinnercaafd772010-09-08 10:51:01 +00004187- Issue #4947: The write() method of sys.stdout and sys.stderr uses their

4189 the same behaviour than the print statement.
4190

4205
4206 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
4207 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
4208

4300 with invalid characters after '=' in a Q-encoded word.
4301
Antoine Pitrou66b5df62010-09-27 18:16:46 +00004302- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
4303 received. Now sendall() properly calls signal handlers if necessary,
4304 and retries sending if these returned successfully, including on sockets
4305 with a timeout.

4316 handles non-blocking readinto() returning None correctly.
4317

4319 SSLSocket.sendto() to match the corresponding socket methods. Also,
4320 fix various SSLSocket methods to raise socket.error rather than an
4321 unhelpful TypeError when called on an unconnected socket. Original patch
4322 by Andrew Bennetts.
4323
Raymond Hettinger74f869e2010-09-13 22:14:36 +00004324- Issue #9826: OrderedDict.__repr__ can now handle self-referential
4325 values: d['x'] = d.
4326
Victor Stinner8fc843b2010-09-17 23:35:50 +00004327- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

4331
Raymond Hettinger20397532010-09-12 02:11:45 +00004332- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4333 This prevents user-created self-referencing ordered dictionaries from
4334 becoming permanently uncollectable GC garbage. The downside is that
4335 removing __del__ means that the internal doubly-linked list has to wait for
4336 GC collection rather than freeing memory immediately when the refcnt drops
4337 to zero.
4338
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004339- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00004340 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004341 value.
4342
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004343- Issue #9792: In case of connection failure, socket.create_connection()
4344 would swallow the exception and raise a new one, making it impossible
4345 to fetch the original errno, or to filter timeout errors. Now the
4346 original error is re-raised.
4347
Antoine Pitrouf4f61712010-09-07 16:34:47 +00004348- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
4349 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
4350 be updated back after the system call. Original patch by Brian Brazil.
4351
Antoine Pitroudca9de92010-09-04 17:52:26 +00004352- Issue #1100562: Fix deep-copying of objects derived from the list and

4356 ConfigParser.write.
4357
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00004358- Issue #808164: Fixed socket.close to avoid references to globals, to
4359 avoid issues when socket.close is called from a __del__ method.
4360
Terry Reedyd2d2ae92010-11-11 23:22:19 +00004361- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
4362 can be set to False to turn off the previously undocumented 'popularity'
4363 heuristic. Patch by Terry Reedy and Eli Bendersky
4364
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00004365- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
4366 falling into recursion.
4367
R. David Murray7c4bf552010-08-25 01:45:57 +00004368- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4369 character years even if the message contains RFC822 two character years.
4370
Daniel Stutzbach91287322010-08-24 21:09:30 +00004371- Issue #8750: Fixed MutableSet's methods to correctly handle

4381
Raymond Hettinger917bba12010-08-22 08:01:58 +00004382- Issue #9214: Set operations on KeysView or ItemsView in the collections
4383 module now correctly return a set. (Patch by Eli Bendersky.)
4384
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004385- Issue #9617: Signals received during a low-level write operation aren't
4386 ignored by the buffered IO layer anymore.
4387
Benjamin Peterson52c36052010-08-21 03:03:22 +00004388- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
4389 are not held onto after they are deleted elsewhere.
4390
Raymond Hettingera54b2da2010-08-17 19:03:06 +00004391- Issue #9626: the view methods for collections.OrderedDict() were returning
4392 the unordered versions inherited from dict. Those methods are now
4393 overridden to provide ordered views.
4394
Éric Araujo0389ae62010-08-14 03:07:46 +00004395- Issue #8688: MANIFEST files created by distutils now include a magic
4396 comment indicating they are generated. Manually maintained MANIFESTs
4397 without this marker will not be overwritten or removed.
4398
Antoine Pitroue1436d12010-08-12 15:25:51 +00004399- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
4400 and a BadZipfile error is raised if it doesn't match (as used to be the
4401 case in Python 2.5 and earlier).
4402
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004403- Issue #9550: a BufferedReader could issue an additional read when the
4404 original read request had been satisfied, which could block indefinitely
4405 when the underlying raw IO channel was e.g. a socket. Report and original
4406 patch by Jason V. Miller.
4407
Fred Drake0a1fa0e2010-08-10 13:09:54 +00004408- Issue #9551: Don't raise TypeError when setting the value to None for

4424 PROT_WRITE and PROT_EXEC.
4425
Senthil Kumarane677ecf2010-08-08 11:56:31 +00004426- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
4427 This is how it is supposed to work, wget and curl do the same. Previous
4428 behavior was wrong.
4429

4793-----------------
4794
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004795- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4796 start byte and the continuation byte(s) are now considered invalid, instead
4797 of the number of bytes specified by the start byte.
4798 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4799 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4800 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4801 Previous versions returned a single u'\ufffd'.

4805 arises from the "Overriding __eq__ blocks inheritance ..." warning
4806 when turned into an exception: in this case the exception simply
4807 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004808
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004809- Issue #8748: Fix two issues with comparisons between complex and integer
4810 objects. (1) The comparison could incorrectly return True in some cases
4811 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4812 (2) The comparison raised an OverflowError for large integers, leading
4813 to unpredictable exceptions when combining integers and complex objects
4814 in sets or dicts.
4815
Mark Dickinson81336372010-05-30 12:12:25 +00004816- Issue #5211: Implicit coercion for the complex type is now completely
4817 removed. (Coercion for arithmetic operations was already removed in 2.7
4818 alpha 4, but coercion for rich comparisons was accidentally left in.)
4819
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004820- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

4822
Georg Brandlfee0f442010-05-22 21:26:21 +00004823- Issue #7902: When using explicit relative import syntax, don't try implicit
4824 relative import semantics.

4827 from another thread. Patch by Daniel Stutzbach.

5008 operation raises multiple signals and more than one of those signals is
5009 trapped, the specification determines the order in which the signals should be

5197 with a non-empty format string. This is an effort to future-proof user
5198 code. If a derived class does not currently implement __format__ but later
5199 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005200 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005201 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005234- Issue #8257: The Decimal construct now accepts a float instance directly,
5235 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005236
5237 >>> Decimal(1.1)
5238 Decimal('1.100000000000000088817841970012523233890533447265625')
5239

Georg Brandlfee0f442010-05-22 21:26:21 +00005251- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5252 InvalidOperation instead of returning False. (Comparisons involving a quiet
5253 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5254 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00005256- Issue #2531: Comparison operations between floats and Decimal instances now
5257 return a result based on the numeric values of the operands; previously they
5258 returned an arbitrary result based on the relative ordering of id(float) and
5259 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005261- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005262 argument `-` which tells it to read files to compile from stdin. Each line is
5263 read on demand and the named file is compiled immediately. (Original patch by
5264 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00005273- Comparisons using one of <, <=, >, >= between a complex instance and a
5274 Fractions instance now raise TypeError instead of returning True/False. This
5275 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5276 <=> complex, and complex <=> complex comparisons.

5385 the set of integer codes for which it was used differed between native packing
5386 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005693- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005694 file position when calling `truncate()`. It would previously change the file
5695 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005696 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5697
Georg Brandlba83f822010-03-14 09:50:54 +00005698- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5699 class used to represent files stored inside an archive. The new
5700 implementation is significantly faster and can be wrapped in a
5701 ``io.BufferedReader`` object for more speedups. It also solves an issue
5702 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005713- Issue #7748: Since unicode values are supported for some metadata options in

5715 encoded string for them. This ensures that the upload and register commands
5716 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00005793- The ``__complex__()`` method is now looked up on the class of instances to
5794 make it consistent with other special methods.

5798
Mark Dickinson1b34d252010-01-01 17:27:30 +00005799- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005800 DeprecationWarning when passed a float argument where an integer was expected.
5801 These functions and methods now raise TypeError instead. The majority of the
5802 effects of this change are in the extension modules, but some core functions
5803 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5804 and many unicode/str methods.

5818 of integers: the result of a/b is now correctly rounded for ints a and b (at
5819 least on IEEE 754 platforms), and in particular does not depend on the
5820 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00005965- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
5966 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00005968- Issue #3382: 'F' formatting for float and complex now convert the result to
5969 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5970 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005971
Georg Brandlba83f822010-03-14 09:50:54 +00005972- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5973 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005974
Georg Brandlba83f822010-03-14 09:50:54 +00005975- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5976 1e-100 used to raise OverflowError, but now gives the requested 120
5977 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00005978
Georg Brandlba83f822010-03-14 09:50:54 +00005979- Add Py3k warnings for parameter names in parentheses.

5984 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005985
Georg Brandlba83f822010-03-14 09:50:54 +00005986- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5987 decimal string that's guaranteed to round back to x under correct rounding
5988 (with round-half-to-even rounding mode). Previously it gave a string based on
5989 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5990 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5991 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005992
Georg Brandlba83f822010-03-14 09:50:54 +00005993- Issue #7117: On almost all platforms: float-to-string and string-to-float
5994 conversions within Python are now correctly rounded. Places these conversions
5995 occur include: str for floats and complex numbers; the float and complex
5996 constructors; old-style and new-style numeric formatting; serialization and
5997 deserialization of floats and complex numbers using marshal, pickle and json;
5998 parsing of float and imaginary literals in Python code; Decimal-to-float
5999 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006000
Georg Brandlba83f822010-03-14 09:50:54 +00006001 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6002 providing correctly-rounded strtod and dtoa C functions. This code is
6003 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6004 the C compiler. There may be a small number of platforms on which correct
6005 operation of this code cannot be guaranteed, so the code is not used: notably,
6006 this applies to platforms where the C double format is not IEEE 754 binary64,
6007 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6008 and Python's configure script is unable to determine how to change the FPU
6009 precision. On these platforms conversions use the platform strtod and dtoa,
6010 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006011
Georg Brandlba83f822010-03-14 09:50:54 +00006012- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6013 uses the correctly-rounded string <-> float conversions described above (when
6014 available), and so produces correctly rounded results that will display nicely
6015 under the float repr. There are two related small changes: (1) round now
6016 accepts any class with an ``__index__()`` method for its second argument (but
6017 no longer accepts floats for the second argument), and (2) an excessively
6018 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6019 raises an exception.

6022
Georg Brandlba83f822010-03-14 09:50:54 +00006023- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00006166- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6167 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6168 but with at least one decimal point and with a default precision
6169 of 12. Previously, the behavior the same but with a default precision of 6.
6170 This more closely matches ``str()``, and reduces surprises when adding
6171 alignment flags to the empty presentation type. This also affects the new
6172 complex.__format__ in the same way.
6173
6174- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
6175 classtype's, even if it was None. property now inserts the __doc__ into the
6176 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00006396- On windows, ``os.chdir()`` given unicode was not working if

6398 this code path is really executed because I cannot move to such directory on
6399 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006401- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6402 element is temporarily replaced with an equivalent frozenset. But the
6403 eventual KeyError would always report the empty ``frozenset()`` as the missing
6404 key. Now it correctly refers to the initial element.

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00007805 AttributeError instead of RuntimeError, depending in which C API call
7806 exactly the recursion limit is exceeded. Consequently, both exception types

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007824- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7825
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007826- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7827 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7828 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7829 ``printf`` function, whereas PyString_FromFormat has an independent
7830 implementation and uses "%zd" on all platforms for size_t values.
7831 This makes a difference on win64, where ``printf`` needs "%Id" to display
7832 64bit values.
7833
Benjamin Peterson97179b02008-09-09 20:55:01 +00007834- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7835 error.
7836
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007837- Issue #3777: long() applied to a float object now always return a long
7838 object; previously an int would be returned for small values. the __long__
7839 method is allowed to return either an int or a long, but the behaviour of
7840 float objects should not change to respect backward compatibility.
7841
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007842- Issue #3751: str.rpartition would perform a left-partition when called with
7843 a unicode argument.
7844
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007845- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007847- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007848 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007849 was correctly parsed but parsing of subsequent arguments failed.
7850
Vinay Sajip35e3b032008-09-01 14:33:59 +00007851- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007852 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7853 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7854 when given a tuple of classes as second argument, were looking up
7855 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7856 type object.
7857
Neal Norwitz18aa3882008-08-24 05:04:52 +00007858- Fix crashes on memory allocation failure found with failmalloc.
7859
7860- Fix memory leaks found with valgrind and update suppressions file.
7861
7862- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Christian Heimes7d4c3172008-08-22 19:47:25 +00007866- Silenced another compiler warning about a used but not defined
7867 function 'stringlib_contains_obj'.

Brett Cannon672237d2008-09-09 00:49:16 +00007901 return a list or None rather than a custom object.
7902
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00007903- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Georg Brandl222e2082010-08-01 22:27:39 +00007926- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00007927 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7928 for catch_warnings() also led to an improvement in the raising of a
7929 DeprecationWarning related to warnings.warn_explicit().
7930
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007931- The deprecation warnings for the old camelCase threading API were removed.

8001-----------------
8002
Guido van Rossumf8402962008-08-20 15:01:50 +00008003- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8004 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8005 extensions do not automatically benefit from the class attribute
8006 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8007 to their tp_flags field if they care. This is a backwards
8008 compatibility feature; in 3.0, all types will use the cache by
8009 default.
8010
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008011- Keyword arguments can now follow starred arguments. (``f(a, *args,
8012 keyword=23)`` is now valid syntax.)
8013
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008014- ctypes function pointers that are COM methods have a boolean True
8015 value again.
8016
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008017- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8018 by denying s# to parse objects that have a releasebuffer procedure,
8019 and introducing s*.
8020
Georg Brandl1e13ea92008-08-11 09:07:59 +00008021- Issue #3537: Fix an assertion failure when an empty but presized dict
8022 object was stored in the freelist.
8023
Mark Dickinsonb6467572008-08-04 21:30:09 +00008024- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8025 ValueError consistently across platforms.
8026
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008027- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8028 (64bit Unix, for example), unichr() would truncate its argument and return
8029 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8030
Neal Norwitze7d8be82008-07-31 17:17:14 +00008031- Apply security patches from Apple.
8032
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008033- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8034 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8035
Antoine Pitrou92f82162008-07-25 22:22:08 +00008036- Issue #1819: function calls with several named parameters are now on
8037 average 35% faster (as measured by pybench).
8038
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008039- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8040 the python debugger steps into a class statement: the free variables (local
8041 variables defined in an outer scope) would be deleted from the outer scope.
8042
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008043- Issue #2620: Overflow checking when allocating or reallocating memory
8044 was not always being done properly in some python types and extension
8045 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8046 all been updated to perform better checks and places in the code that
8047 would previously leak memory on the error path when such an allocation
8048 failed have been fixed.

8052
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00008053- Issue #3612: Added some missing basic types in ctypes.wintypes.
8054
Benjamin Petersone977ad42008-08-20 01:42:01 +00008055- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8056 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8057
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008058- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8059 version reported by these tools does not necessarily follow the python
8060 version numbering scheme, so the module is less strict when parsing it.
8061
Nick Coghlanf70385a2008-08-18 12:42:46 +00008062- Issue #2235: Added Py3k warnings for types which will become unhashable
8063 under the stricter __hash__ inheritance rules in 3.0. Several types
8064 which did not meet the rules for hash invariants and were already
8065 unhashable in 3.0 have now been explicitly flagged as unhashable in
8066 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8067 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8068
Brett Cannon88f801d2008-08-18 00:46:22 +00008069- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8070 imported into the module but exposed as part of the module's API.
8071

8196
Georg Brandl3e483f62008-07-16 22:57:41 +00008197- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8198 its methods now allow for items objects that can be converted to
8199 an integer using operator.index().
8200
Mark Dickinson64b7e502008-07-16 09:40:03 +00008201- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8202 produced a ValueError instead of giving the correct float.
8203
Eric Smitha5fa5a22008-07-16 00:11:49 +00008204- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8205 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8206
Mark Dickinson7103aa42008-07-15 19:08:33 +00008207- Issue #3008: the float type has a new instance method 'float.hex'
8208 and a new class method 'float.fromhex' to convert floating-point
8209 numbers to and from hexadecimal strings, respectively.
8210
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008211- Issue #2235: __hash__ is once again inherited by default. To allow
8212 collections.Hashable to remain meaningful in the presence of the
8213 default hash implementation (object.__hash__), it is now possible
8214 to explicit block inheritance of hash by setting __hash__=None at
8215 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8216 level.
8217
Nick Coghlanb028f502008-07-13 14:52:36 +00008218- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8219 the parent module cannot be found while performing an absolute import.
8220 This means that an incorrectly defined __package__ attribute will
8221 now only prevent relative imports in that module rather than causing
8222 all imports from that module to fail.
8223
Nick Coghlan14ff9942008-07-08 14:21:42 +00008224- Issue #2517: Allow unicode messages in Exceptions again by correctly

8234 another thread's dictionary.
8235
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008236- Issue #3004: Minor change to slice.indices(): the start and stop
8237 arguments are now treated identically, making the behaviour easier
8238 to describe and understand. For example, slice(None, -10,
8239 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8240 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8241 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008243- Issue #3219: Calling a function with repeated keyword arguments,

8284 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008285 wrong because the actual transmitted size could differ from the

8690
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008691- On MacOS X it is now possible to install the framework in 64-bit
8692 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008693 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008694
8695 This is controlled by the configure argument ``--with-universal-archs``:
8696
8697 - ``--with-universal-archs=all``: install 4-way universal
8698
8699 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8700
8701 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8702
8703 This option should be used in combination with ``--enable-universalsdk=``.
8704
8705 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 +00008754- Issue #1631171: Re-implement the 'warnings' module in C (the
8755 original Python code has been kept as backup). This will allow for
8756 using the 'warning's machinery in such places as the parser where
8757 use of pure Python code is not possible. Both the ``showarning()``
8758 and ``formatwarning()`` gain an optional 'line' argument which is
8759 not called by default for backwards-compatibility reasons. Setting
8760 ``warnings.showwarning()`` to an implementation that lacks support
8761 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008824- Issue #2550: The approach used by client/server code for obtaining
8825 ports to listen on in network-oriented tests has been refined in an
8826 effort to facilitate running multiple instances of the entire
8827 regression test suite in parallel without issue.
8828 test_support.bind_port() has been fixed such that it will always
8829 return a unique port -- which wasn't always the case with the
8830 previous implementation, especially if socket options had been set
8831 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8832 new implementation of bind_port() will actually raise an exception
8833 if it is passed an AF_INET/SOCK_STREAM socket with either the
8834 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8835 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8836 the socket it's been passed. This currently only applies to
8837 Windows. This option prevents any other sockets from binding to the
8838 host/port we've bound to, thus removing the possibility of the
8839 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8840 when a second SOCK_STREAM socket binds and accepts to a host/port
8841 that's already been bound by another socket. The optional preferred
8842 port parameter to bind_port() has been removed. Under no
8843 circumstances should tests be hard coding ports!
8844
8845 test_support.find_unused_port() has also been introduced, which will
8846 pass a temporary socket object to bind_port() in order to obtain an
8847 unused port. The temporary socket object is then closed and
8848 deleted, and the port is returned. This method should only be used
8849 for obtaining an unused port in order to pass to an external program
8850 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8851 a parameter to a server-oriented class that doesn't give you direct
8852 access to the underlying socket used.
8853
8854 Finally, test_support.HOST has been introduced, which should be used
8855 for the host argument of any relevant socket calls (i.e. bind and
8856 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008857
8858 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008859 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008860 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8861 test_asynchat and test_socket_ssl.
8862
Georg Brandl3ee81df2008-05-17 18:14:43 +00008863 It is now possible for multiple instances of the regression test
8864 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00008918- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00008919 \Uxxxxxxxx did not accept values outside the Basic Multilingual
8920 Plane. This affected raw unicode literals and the
8921 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
8922 this case, like normal unicode literals and the 'unicode-escape'
8923 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00009143- Added the future_builtins module, which contains hex() and oct().
9144 These are the PEP 3127 version of these functions, designed to be
9145 compatible with the hex() and oct() builtins from Python 3.0. They
9146 differ slightly in their output formats from the existing, unchanged
9147 Python 2.6 builtins. The expected usage of the future_builtins
9148 module is:
9149 from future_builtins import hex, oct
9150
Eric Smith7ef40bf2008-02-20 23:34:22 +00009151- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9152 exponents for exponents with absolute value < 100. Follows C99
9153 standard. This is a change on Windows, which would use 3 digits.
9154 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9155 so that any alterations it does to the resulting string will be
9156 available in stringlib/formatter.h (for float.__format__).
9157
Eric Smith5a3c1352008-02-19 13:21:56 +00009158- Implemented PEP 3101, Advanced String Formatting. This adds a new
9159 builtin format(); a format() method for str and unicode; a
9160 __format__() method to object, str, unicode, int, long, float, and
9161 datetime; the class string.Formatter; and the C API
9162 PyObject_Format().
9163
Georg Brandl3ee81df2008-05-17 18:14:43 +00009164- Fixed several potential crashes, all caused by specially crafted
9165 __del__ methods exploiting objects in temporarily inconsistent
9166 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009167
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009168- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169 prevent a possible crash: an Abstract Base Class would try to access
9170 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009171

Georg Brandl3ee81df2008-05-17 18:14:43 +00009209- Patch #1473257: generator objects gain a gi_code attribute. This is
9210 the same object as the func_code attribute of the function that
9211 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009212
Georg Brandl3ee81df2008-05-17 18:14:43 +00009213- Issue #1920: "while 0" statements were completely removed by the
9214 compiler, even in the presence of an "else" clause, which is
9215 supposed to be run when the condition is false. Now the compiler
9216 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009217
Guido van Rossumeead05f2008-01-24 18:21:02 +00009218- A few crashers fixed: weakref_in_del.py (issue #1377858);

9225
Georg Brandl3ee81df2008-05-17 18:14:43 +00009226- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009227 several extension methods and modules do not work without unicode
9228 support.
9229
Georg Brandl26543b12008-01-21 18:36:51 +00009230- Issue #1882: when compiling code from a string, encoding cookies in the

9234
Georg Brandl6caad7d2008-01-26 14:19:22 +00009235- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009236 added.
9237
Christian Heimesc94e2b52008-01-14 04:13:37 +00009238- sys.float_info / PyFloat_GetInfo: The floating point information
9239 object was converted from a dict to a specialized structseq object.
9240
Georg Brandl3ee81df2008-05-17 18:14:43 +00009241- Patch #1816: Added sys.flags structseq. It exposes the status of
9242 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009243
Georg Brandl3ee81df2008-05-17 18:14:43 +00009244- Objects/structseq.c: Implemented new structseq representation. The
9245 patch makes structseqs (e.g. the return value of os.stat) more
9246 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009247
Georg Brandl3ee81df2008-05-17 18:14:43 +00009248- Patch #1700288: added a type attribute cache that caches method
9249 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009250
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009251- Bug #1776: __import__() no longer accepts filenames on any platform.

9257 envvar and sys.dont_write_bytecode attribute. All these can be set
9258 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009259
Georg Brandl3ee81df2008-05-17 18:14:43 +00009260- Improve some exception messages when Windows fails to load an
9261 extension module. Now we get for example '%1 is not a valid Win32
9262 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009269- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009270 and INF. float("nan"), float("inf") and float("-inf") now work on
9271 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009272
Georg Brandl3ee81df2008-05-17 18:14:43 +00009273- Compiler now generates simpler and faster code for dictionary

9319
Georg Brandl21e99f42010-03-07 15:23:59 +00009320- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009321 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9322 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009323
Georg Brandl3ee81df2008-05-17 18:14:43 +00009324- Issue #1686386: Tuple's tp_repr did not take into account the
9325 possibility of having a self-referential tuple, which is possible
9326 from C code. Nor did object's tp_str consider that a type's tp_str
9327 could do something that could lead to an inifinite recursion.
9328 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9329 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009330
Georg Brandl3ee81df2008-05-17 18:14:43 +00009331- Issue #1164: It was possible to trigger deadlock when using the
9332 'print' statement to write to a file since the GIL was not released
9333 as needed. Now PyObject_Print() does the right thing along with
9334 various tp_print implementations of the built-in types and those in
9335 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009336

Georg Brandl3ee81df2008-05-17 18:14:43 +00009345 PyObject_Call() never calling back out to Python code to trigger
9346 recursion depth updates/checks. Required the creation of a static
9347 RuntimeError instance in case normalizing an exception put the
9348 recursion check value past its limit. Fixes crashers

9372 calls.
9373
Collin Winter62903052007-05-18 23:11:24 +00009374- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009375 "except E as target:". This is to provide forwards compatibility

Guido van Rossum143b5642007-03-23 04:58:42 +00009397- Bug #1683368: The object.__init__() and object.__new__() methods are
9398 now stricter in rejecting excess arguments. The only time when
9399 either allows excess arguments is when it is not overridden and the
9400 other one is. For backwards compatibility, when both are
9401 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009402 warning later). Also, type.__init__() insists on the same signature
9403 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009405- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9406 object to complex using its __complex__() method before falling back
9407 to the __float__() method. Therefore, the functions in the cmath
9408 module now can operate on objects that define a __complex__()
9409 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009427- Bug #1678647: write a newline after printing an exception in any
9428 case, even when converting the value to a string failed.
9429
Georg Brandl871f1bc2007-03-12 13:17:36 +00009430- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009431 its argument, if it exists. If not, it will work like before. This
9432 allows customizing the output of dir() in the presence of a
9433 __getattr__().

9443 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00009445- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009446 makes the filenames the warning module prints much more sensible
9447 when a PYTHONSTARTUP file is used.

9461 sq_ass_slice instead of the sq_slice slot.
9462
Georg Brandl3ee81df2008-05-17 18:14:43 +00009463- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00009515- Bug #1545497: when given an explicit base, int() did ignore NULs
9516 embedded in the string to convert.
9517
Georg Brandl846f73a2006-10-08 07:11:54 +00009518- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00009548- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
9549 Also make sure that every exception class has __module__ set to

Georg Brandl3ee81df2008-05-17 18:14:43 +00009566 generator expressions (x for x, in ... ) works again. Fixing this
9567 problem required changing the .pyc magic number. This means that
9568 .pyc files generated before 2.5c2 will be regenerated.

10359
Georg Brandl3ee81df2008-05-17 18:14:43 +000010360- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
10361 the first chunk fed to the decoder started with a BOM, but was
10362 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010363
Georg Brandl3ee81df2008-05-17 18:14:43 +000010364- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010368- Issue #829951: In the smtplib module, SMTP.starttls() now complies
10369 with RFC 3207 and forgets any knowledge obtained from the server not
10370 obtained from the TLS negotiation itself. Patch contributed by Bill
10371 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010372
Georg Brandl3ee81df2008-05-17 18:14:43 +000010373- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010374 that the SMTP.starttls() caller no longer needs to call ehlo()
10375 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010376 does not claim to support starttls. Adds the
10377 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl309501a2008-01-19 20:22:13 +000010419
Georg Brandl3ee81df2008-05-17 18:14:43 +000010420- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010421 works as expected. ``mmap.find`` also takes an optional ``end``

10447 contents before adding elements from the iterable. This fix brings
10448 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +000010449
Georg Brandl3ee81df2008-05-17 18:14:43 +000010450- Added wide char functions to msvcrt module: getwch, getwche, putwch

10456
Georg Brandl3ee81df2008-05-17 18:14:43 +000010457- Marshal.dumps() now expects exact type matches for int, long, float,
10458 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10459 silently miscode subclasses of those types. Now, it raises a
10460 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010461

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010475- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010476 time so that opening a database previously created with the DB_DUP
10477 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10478 opens. Specifically: dictionary assignment to a DB object will
10479 replace all values for a given key when the database allows
10480 duplicate values. DB users should use DB.put(k, v) when they want
10481 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010482

Georg Brandl3ee81df2008-05-17 18:14:43 +000010487- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
10488 characters with ASCII value less than 32. Also, it correctly quotes
10489 dots only if they occur on a single line, as opposed to the previous
10490 behavior of quoting dots if they are the second character of any
10491 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010492

Georg Brandl3ee81df2008-05-17 18:14:43 +000010841- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10842 of w# format code incorrectly truncated the length to an int, even
10843 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10844 incorrect results with huge strings.

10854 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010855
10856- Patch #1733960: Allow T_LONGLONG to accept ints.
10857

10863
10864- Fix some leftovers from the conversion from int to Py_ssize_t
10865 (relevant to strings and sequences of more than 2**31 items).
10866
10867- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10868 outside of pystate.c and should not be necessary.
10869
Georg Brandl3ee81df2008-05-17 18:14:43 +000010870- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10871 absolute imports. In earlier versions they might have used relative
10872 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010873
Georg Brandl3ee81df2008-05-17 18:14:43 +000010874- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10875 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010883- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10884 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10885 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10886 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010900- Removed the macfs module. It had been deprecated since Python 2.5.
10901 This lead to the deprecation of macostools.touched() as it relied
10902 solely on macfs and was a no-op under OS X.
