1209
1210- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1211 and later systems as is currently done for Python 3.x installers.
1212 For 2.7.7 only, we will provide three installers:
1213 the legacy deprecated 10.3+ 32-bit-only format;
1214 the newer 10.5+ 32-bit-only format;
1215 and the unchanged 10.6+ 64-/32-bit format.
1216 Although binary installers will no longer be available from
1217 python.org as of 2.7.8, it will still be possible to build from
1218 source on 10.3.9 and 10.4 systems if necessary.
1219 See Mac/BuildScript/README.txt for more information.

2601 32-bit-only installer Pythons on systems with Xcode 4 (currently
2602 OS X 10.8, 10.7, and optionally 10.6).
2603 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2604 * Since Xcode 4 removes ppc support, extension module builds now
2605 check for ppc compiler support and by default remove ppc and
2606 ppc64 archs when they are not available.
2607 * Extension module builds now revert to using system installed
2608 headers and libs (/usr and /System/Library) if the SDK used
2609 to build the interpreter is not installed or has moved.
2610 * Try to avoid building extension modules with deprecated
2611 and problematic Apple llvm-gcc compiler. If original compiler
2612 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003049- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003050 has left two versions of customize_compiler, the original in
3051 distutils.sysconfig and another copy in distutils.ccompiler, with some
3052 parts of distutils calling one and others using the other.

3054 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01003056- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3057 Distutils-based packages with C extension modules may fail because
3058 Apple has removed gcc-4.2, the version used to build python.org
3059 64-bit/32-bit Pythons. If the user does not explicitly override
3060 the default C compiler by setting the CC environment variable,
3061 Distutils will now attempt to compile extension modules with clang
3062 if gcc-4.2 is required but not found. Also as a convenience, if
3063 the user does explicitly set CC, substitute its value as the default
3064 compiler in the Distutils LDSHARED configuration variable for OS X.
3065 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3066 SDK, neither of which are available in Xcode 4. This change does not
3067 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003317- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3318 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3319 interpreter process. This could cause failures in non-Distutils subprocesses
3320 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003321 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003322 deployment target only in the environment of each build subprocess. It is
3323 still possible to globally override the default by setting
3324 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3325 greater or equal to the default value, the value with which the interpreter
3326 was built.

3355 updating the check interval, so if the user decreases the check interval,
3356 the ticker doesn't have to wind down to zero from the old starting point
3357 before the new interval takes effect. And if the user increases the
3358 interval, it makes sure the new limit takes effect right away rather have an
3359 early task switch before recognizing the new interval.

Antoine Pitroue4195e82010-09-12 14:56:27 +00004353- Issue #9837: The read() method of ZipExtFile objects (as returned by

4355
Raymond Hettinger20397532010-09-12 02:11:45 +00004356- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4357 This prevents user-created self-referencing ordered dictionaries from
4358 becoming permanently uncollectable GC garbage. The downside is that
4359 removing __del__ means that the internal doubly-linked list has to wait for
4360 GC collection rather than freeing memory immediately when the refcnt drops
4361 to zero.
4362

4366
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004367- Issue #9792: In case of connection failure, socket.create_connection()
4368 would swallow the exception and raise a new one, making it impossible
4369 to fetch the original errno, or to filter timeout errors. Now the
4370 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004819- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4820 start byte and the continuation byte(s) are now considered invalid, instead
4821 of the number of bytes specified by the start byte.
4822 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4823 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4824 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4825 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004833- Issue #8748: Fix two issues with comparisons between complex and integer
4834 objects. (1) The comparison could incorrectly return True in some cases
4835 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4836 (2) The comparison raised an OverflowError for large integers, leading
4837 to unpredictable exceptions when combining integers and complex objects

5221 with a non-empty format string. This is an effort to future-proof user
5222 code. If a derived class does not currently implement __format__ but later

Georg Brandlba83f822010-03-14 09:50:54 +00005718 file position when calling `truncate()`. It would previously change the file
5719 position to the given argument, which goes against the tradition of

5726 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5815-----------------
5816
Georg Brandlba83f822010-03-14 09:50:54 +00005817- The ``__complex__()`` method is now looked up on the class of instances to
5818 make it consistent with other special methods.

5822
Mark Dickinson1b34d252010-01-01 17:27:30 +00005823- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005824 DeprecationWarning when passed a float argument where an integer was expected.
5825 These functions and methods now raise TypeError instead. The majority of the
5826 effects of this change are in the extension modules, but some core functions
5827 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5828 and many unicode/str methods.

5842 of integers: the result of a/b is now correctly rounded for ints a and b (at
5843 least on IEEE 754 platforms), and in particular does not depend on the
5844 internal representation of a long.

5852
Georg Brandlba83f822010-03-14 09:50:54 +00005853 These executables now work properly with the arch(1) command: ``arch -ppc

5940 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5941 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5942 float arguments for integer format codes (other than 'L'): previously an
5943 attempt to pass a float resulted in a DeprecationWarning; now it gives a
5944 TypeError. For the 'L' format code (which previously had no warning) there is
5945 now a DeprecationWarning.

5994 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005995

5997 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00006009
Georg Brandlba83f822010-03-14 09:50:54 +00006010- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6011 decimal string that's guaranteed to round back to x under correct rounding
6012 (with round-half-to-even rounding mode). Previously it gave a string based on
6013 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6014 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6015 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006016
Georg Brandlba83f822010-03-14 09:50:54 +00006017- Issue #7117: On almost all platforms: float-to-string and string-to-float
6018 conversions within Python are now correctly rounded. Places these conversions
6019 occur include: str for floats and complex numbers; the float and complex
6020 constructors; old-style and new-style numeric formatting; serialization and
6021 deserialization of floats and complex numbers using marshal, pickle and json;
6022 parsing of float and imaginary literals in Python code; Decimal-to-float
6023 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006024
Georg Brandlba83f822010-03-14 09:50:54 +00006025 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6026 providing correctly-rounded strtod and dtoa C functions. This code is
6027 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6028 the C compiler. There may be a small number of platforms on which correct
6029 operation of this code cannot be guaranteed, so the code is not used: notably,
6030 this applies to platforms where the C double format is not IEEE 754 binary64,
6031 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6032 and Python's configure script is unable to determine how to change the FPU
6033 precision. On these platforms conversions use the platform strtod and dtoa,
6034 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006035
Georg Brandlba83f822010-03-14 09:50:54 +00006036- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6037 uses the correctly-rounded string <-> float conversions described above (when
6038 available), and so produces correctly rounded results that will display nicely
6039 under the float repr. There are two related small changes: (1) round now
6040 accepts any class with an ``__index__()`` method for its second argument (but
6041 no longer accepts floats for the second argument), and (2) an excessively
6042 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6043 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006173- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
6174 consistent with float("1e500") and interpretation of real and imaginary
6175 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00006184- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00006185
Georg Brandlba83f822010-03-14 09:50:54 +00006186 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
6187 (2) parsing of strings representing infinities and nans was locale aware; and
6188 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00006190- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6191 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6192 but with at least one decimal point and with a default precision
6193 of 12. Previously, the behavior the same but with a default precision of 6.
6194 This more closely matches ``str()``, and reduces surprises when adding
6195 alignment flags to the empty presentation type. This also affects the new
6196 complex.__format__ in the same way.
6197
6198- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
6199 classtype's, even if it was None. property now inserts the __doc__ into the
6200 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00006260- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00006261 untrackable objects are not tracked by the garbage collector. This can reduce
6262 the size of collections and therefore the garbage collection overhead on

6270 internal representation of integers, for performance reasons. Base 2**30 is
6271 enabled by default on 64-bit machines. Add --enable-big-digits option to
6272 configure, which overrides the default. Add sys.long_info structseq to
6273 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00006420- On windows, ``os.chdir()`` given unicode was not working if

6422 this code path is really executed because I cannot move to such directory on
6423 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006425- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6426 element is temporarily replaced with an equivalent frozenset. But the
6427 eventual KeyError would always report the empty ``frozenset()`` as the missing
6428 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006448- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6449 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6450 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6451 of using the replace error handler in PyUnicode_DecodeUTF8().
6452
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006453- Issue #3739: The unicode-internal encoder now reports the number of characters

6455
Georg Brandlba83f822010-03-14 09:50:54 +00006456- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6457 allocator will be automatically disabled when running under Valgrind. This
6458 gives improved memory leak detection when running under Valgrind, while taking
6459 advantage of pymalloc at other times.

7650 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7651 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007848- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7849
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007850- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7851 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7852 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7853 ``printf`` function, whereas PyString_FromFormat has an independent
7854 implementation and uses "%zd" on all platforms for size_t values.
7855 This makes a difference on win64, where ``printf`` needs "%Id" to display
7856 64bit values.
7857
Benjamin Peterson97179b02008-09-09 20:55:01 +00007858- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7862 object; previously an int would be returned for small values. the __long__
7863 method is allowed to return either an int or a long, but the behaviour of
7864 float objects should not change to respect backward compatibility.
7865
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007866- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00007872 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007873 was correctly parsed but parsing of subsequent arguments failed.
7874
Vinay Sajip35e3b032008-09-01 14:33:59 +00007875- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007876 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7877 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7878 when given a tuple of classes as second argument, were looking up
7879 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7880 type object.
7881

Brett Cannon1eaf0742008-09-02 01:25:16 +00007951 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7952 for catch_warnings() also led to an improvement in the raising of a

8025-----------------
8026
Guido van Rossumf8402962008-08-20 15:01:50 +00008027- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8028 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8029 extensions do not automatically benefit from the class attribute
8030 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8031 to their tp_flags field if they care. This is a backwards
8032 compatibility feature; in 3.0, all types will use the cache by
8033 default.
8034
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008035- Keyword arguments can now follow starred arguments. (``f(a, *args,
8036 keyword=23)`` is now valid syntax.)
8037
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008038- ctypes function pointers that are COM methods have a boolean True
8039 value again.

Georg Brandl1e13ea92008-08-11 09:07:59 +00008045- Issue #3537: Fix an assertion failure when an empty but presized dict
8046 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00008048- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8049 ValueError consistently across platforms.
8050
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008051- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8052 (64bit Unix, for example), unichr() would truncate its argument and return
8053 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8054
Neal Norwitze7d8be82008-07-31 17:17:14 +00008055- Apply security patches from Apple.
8056
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008057- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

8059
Antoine Pitrou92f82162008-07-25 22:22:08 +00008060- Issue #1819: function calls with several named parameters are now on
8061 average 35% faster (as measured by pybench).
8062
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008063- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8064 the python debugger steps into a class statement: the free variables (local
8065 variables defined in an outer scope) would be deleted from the outer scope.
8066
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008067- Issue #2620: Overflow checking when allocating or reallocating memory
8068 was not always being done properly in some python types and extension
8069 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8070 all been updated to perform better checks and places in the code that
8071 would previously leak memory on the error path when such an allocation
8072 failed have been fixed.

8080 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8081
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008082- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8083 version reported by these tools does not necessarily follow the python
8084 version numbering scheme, so the module is less strict when parsing it.
8085
Nick Coghlanf70385a2008-08-18 12:42:46 +00008086- Issue #2235: Added Py3k warnings for types which will become unhashable
8087 under the stricter __hash__ inheritance rules in 3.0. Several types
8088 which did not meet the rules for hash invariants and were already
8089 unhashable in 3.0 have now been explicitly flagged as unhashable in
8090 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8091 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8092
Brett Cannon88f801d2008-08-18 00:46:22 +00008093- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8094 imported into the module but exposed as part of the module's API.
8095

8119 regular expression.
8120
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008121- Issue #3476: binary buffered reading through the new "io" library is now
8122 thread-safe.
8123
Brett Cannonbf3157b2008-08-14 05:00:03 +00008124- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8125 since mimetools itself is deprecated. Because modules are cached, all
8126 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8127
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008128- Issue #3134: shutil referenced undefined WindowsError symbol.

8137 a MemoryError rather than silently stop the iteration.
8138
Guido van Rossum59ce9012008-08-09 14:55:34 +00008139- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8140 to _sre.compile() will now be rejected. This should not affect anybody
8141 since the re.compile() function never generates invalid re-bytecode.
8142
Skip Montanaroa032bf42008-08-08 22:52:51 +00008143- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8144 upon first access it can be automatically initialized from the csv file if
8145 it wasn't initialized during instantiation.
8146
Brett Cannon3aa2a492008-08-06 22:28:09 +00008147- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8148 the reload() built-in has been removed.
8149
Brett Cannon7e30b672008-08-04 21:52:25 +00008150- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00008162 asking for a specific length. This problem only affected files opened
8163 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008188- Issue #3394: zipfile.writestr sets external attributes when passed a
8189 file name rather than a ZipInfo instance, so files are extracted with
8190 mode 0600 rather than 000 under Unix.
8191
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008192- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

8205 interaction with the tp_hash slot (added in 2.6b2) are now documented
8206
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008207- Issue #643841: The language reference now provides more detailed
8208 coverage of the lookup process for special methods. The disclaimers
8209 regarding lack of coverage of new-style classes have also been
8210 removed, since the coverage is now fairly reasonable.

8214================================
8215
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008216*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00008218Core and Builtins
8219-----------------
8220
Georg Brandl3e483f62008-07-16 22:57:41 +00008221- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8222 its methods now allow for items objects that can be converted to
8223 an integer using operator.index().
8224
Mark Dickinson64b7e502008-07-16 09:40:03 +00008225- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8226 produced a ValueError instead of giving the correct float.
8227
Eric Smitha5fa5a22008-07-16 00:11:49 +00008228- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8229 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8230
Mark Dickinson7103aa42008-07-15 19:08:33 +00008231- Issue #3008: the float type has a new instance method 'float.hex'
8232 and a new class method 'float.fromhex' to convert floating-point
8233 numbers to and from hexadecimal strings, respectively.
8234
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008235- Issue #2235: __hash__ is once again inherited by default. To allow
8236 collections.Hashable to remain meaningful in the presence of the
8237 default hash implementation (object.__hash__), it is now possible
8238 to explicit block inheritance of hash by setting __hash__=None at
8239 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8240 level.
8241
Nick Coghlanb028f502008-07-13 14:52:36 +00008242- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8243 the parent module cannot be found while performing an absolute import.
8244 This means that an incorrectly defined __package__ attribute will
8245 now only prevent relative imports in that module rather than causing
8246 all imports from that module to fail.
8247
Nick Coghlan14ff9942008-07-08 14:21:42 +00008248- Issue #2517: Allow unicode messages in Exceptions again by correctly
8249 bypassing the instance dictionary when looking up __unicode__ on
8250 new-style classes.
8251
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008252- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8253 set to a custom object whose write() method happens to install
8254 another file in sys.stdout.
8255
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008256- Issue #3088: Corrected a race condition in classes derived from
8257 threading.local: the first member set by a thread could be saved in
8258 another thread's dictionary.
8259
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008260- Issue #3004: Minor change to slice.indices(): the start and stop
8261 arguments are now treated identically, making the behaviour easier
8262 to describe and understand. For example, slice(None, -10,
8263 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8264 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8265 10, -1).
8266
Georg Brandl278fc502008-07-19 12:46:12 +00008267- Issue #3219: Calling a function with repeated keyword arguments,
8268 f(a=2, a=23), would not cause a syntax error. This was a regression
8269 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008270
Georg Brandl278fc502008-07-19 12:46:12 +00008271- Issue #2862: Make int and float freelist management consistent with
8272 other freelists. Changes their CompactFreeList apis into
8273 ClearFreeList apis and calls them via gc.collect().

8279 api functions without holding the GIL, which could lead to a fatal
8280 error when they failed.
8281
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008282- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

8291 ForkingPickler.register() to resolve conflict with ctypes.

Vinay Sajip51e65192008-07-18 09:01:10 +00008293- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller2bad6572008-07-15 17:19:50 +00008298- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8299 incomplete structure was created.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008307- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8308 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008309 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008310 content-length. The problem had been corrected in the 2.4 branch, but never
8311 merged into trunk.
8312

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008326- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8327 handling is now the same as that of other special attributes like __name__).
8328
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008329- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
8330 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008717 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008718
8719 This is controlled by the configure argument ``--with-universal-archs``:
8720
8721 - ``--with-universal-archs=all``: install 4-way universal
8722
8723 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8724
8725 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8726
8727 This option should be used in combination with ``--enable-universalsdk=``.
8728
8729 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 +00008778- Issue #1631171: Re-implement the 'warnings' module in C (the
8779 original Python code has been kept as backup). This will allow for
8780 using the 'warning's machinery in such places as the parser where
8781 use of pure Python code is not possible. Both the ``showarning()``
8782 and ``formatwarning()`` gain an optional 'line' argument which is
8783 not called by default for backwards-compatibility reasons. Setting
8784 ``warnings.showwarning()`` to an implementation that lacks support
8785 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008848- Issue #2550: The approach used by client/server code for obtaining
8849 ports to listen on in network-oriented tests has been refined in an
8850 effort to facilitate running multiple instances of the entire
8851 regression test suite in parallel without issue.
8852 test_support.bind_port() has been fixed such that it will always
8853 return a unique port -- which wasn't always the case with the
8854 previous implementation, especially if socket options had been set
8855 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8856 new implementation of bind_port() will actually raise an exception
8857 if it is passed an AF_INET/SOCK_STREAM socket with either the
8858 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8859 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8860 the socket it's been passed. This currently only applies to
8861 Windows. This option prevents any other sockets from binding to the
8862 host/port we've bound to, thus removing the possibility of the
8863 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8864 when a second SOCK_STREAM socket binds and accepts to a host/port
8865 that's already been bound by another socket. The optional preferred
8866 port parameter to bind_port() has been removed. Under no
8867 circumstances should tests be hard coding ports!
8868
8869 test_support.find_unused_port() has also been introduced, which will
8870 pass a temporary socket object to bind_port() in order to obtain an
8871 unused port. The temporary socket object is then closed and
8872 deleted, and the port is returned. This method should only be used
8873 for obtaining an unused port in order to pass to an external program
8874 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8875 a parameter to a server-oriented class that doesn't give you direct
8876 access to the underlying socket used.
8877
8878 Finally, test_support.HOST has been introduced, which should be used
8879 for the host argument of any relevant socket calls (i.e. bind and
8880 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008881
8882 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008883 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008884 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8885 test_asynchat and test_socket_ssl.
8886
Georg Brandl3ee81df2008-05-17 18:14:43 +00008887 It is now possible for multiple instances of the regression test
8888 suite to run in parallel without issue.

Facundo Batistafc2d0102008-02-23 12:01:13 +00009166
Eric Smitha73fbe72008-02-23 03:09:44 +00009167- Added the future_builtins module, which contains hex() and oct().
9168 These are the PEP 3127 version of these functions, designed to be
9169 compatible with the hex() and oct() builtins from Python 3.0. They
9170 differ slightly in their output formats from the existing, unchanged
9171 Python 2.6 builtins. The expected usage of the future_builtins
9172 module is:
9173 from future_builtins import hex, oct
9174
Eric Smith7ef40bf2008-02-20 23:34:22 +00009175- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9176 exponents for exponents with absolute value < 100. Follows C99
9177 standard. This is a change on Windows, which would use 3 digits.
9178 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9179 so that any alterations it does to the resulting string will be
9180 available in stringlib/formatter.h (for float.__format__).
9181
Eric Smith5a3c1352008-02-19 13:21:56 +00009182- Implemented PEP 3101, Advanced String Formatting. This adds a new
9183 builtin format(); a format() method for str and unicode; a
9184 __format__() method to object, str, unicode, int, long, float, and
9185 datetime; the class string.Formatter; and the C API
9186 PyObject_Format().
9187
Georg Brandl3ee81df2008-05-17 18:14:43 +00009188- Fixed several potential crashes, all caused by specially crafted
9189 __del__ methods exploiting objects in temporarily inconsistent
9190 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009191
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009192- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009193 prevent a possible crash: an Abstract Base Class would try to access
9194 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009195

Georg Brandl3ee81df2008-05-17 18:14:43 +00009199- Clear all free lists during a gc.collect() of the highest generation
9200 in order to allow pymalloc to free more arenas. Python may give back
9201 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009202
Georg Brandl3ee81df2008-05-17 18:14:43 +00009203- Issue #2045: Fix an infinite recursion triggered when printing a
9204 subclass of collections.defaultdict, if its default_factory is set
9205 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00009207- Fixed a minor memory leak in dictobject.c. The content of the free
9208 list was not freed on interpreter shutdown.
9209
Georg Brandl21e99f42010-03-07 15:23:59 +00009210- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009211 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009212
Georg Brandl3ee81df2008-05-17 18:14:43 +00009213- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9214 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009215 to compact the internal free lists of pre-allocted ints and floats.
9216
Georg Brandl3ee81df2008-05-17 18:14:43 +00009217- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9218 calls. Python expected the return type int but the fork familie
9219 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009233- Patch #1473257: generator objects gain a gi_code attribute. This is
9234 the same object as the func_code attribute of the function that
9235 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009236
Georg Brandl3ee81df2008-05-17 18:14:43 +00009237- Issue #1920: "while 0" statements were completely removed by the
9238 compiler, even in the presence of an "else" clause, which is
9239 supposed to be run when the condition is false. Now the compiler
9240 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009241
Guido van Rossumeead05f2008-01-24 18:21:02 +00009242- A few crashers fixed: weakref_in_del.py (issue #1377858);
9243 loosing_dict_ref.py (issue #1303614, test67.py);
9244 borrowed_ref_[34].py (not in tracker).
9245
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009246- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009247 suppressed while an extension is loaded by calling SetErrorMode in
9248 dynload_win.c. The error is still reported properly.
9249
Georg Brandl3ee81df2008-05-17 18:14:43 +00009250- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009251 several extension methods and modules do not work without unicode
9252 support.
9253
Georg Brandl26543b12008-01-21 18:36:51 +00009254- Issue #1882: when compiling code from a string, encoding cookies in the

9258
Georg Brandl6caad7d2008-01-26 14:19:22 +00009259- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009260 added.
9261
Christian Heimesc94e2b52008-01-14 04:13:37 +00009262- sys.float_info / PyFloat_GetInfo: The floating point information
9263 object was converted from a dict to a specialized structseq object.
9264
Georg Brandl3ee81df2008-05-17 18:14:43 +00009265- Patch #1816: Added sys.flags structseq. It exposes the status of
9266 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009267
Georg Brandl3ee81df2008-05-17 18:14:43 +00009268- Objects/structseq.c: Implemented new structseq representation. The
9269 patch makes structseqs (e.g. the return value of os.stat) more
9270 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009271
Georg Brandl3ee81df2008-05-17 18:14:43 +00009272- Patch #1700288: added a type attribute cache that caches method
9273 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009274
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009275- Bug #1776: __import__() no longer accepts filenames on any platform.

9281 envvar and sys.dont_write_bytecode attribute. All these can be set
9282 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009283
Georg Brandl3ee81df2008-05-17 18:14:43 +00009284- Improve some exception messages when Windows fails to load an
9285 extension module. Now we get for example '%1 is not a valid Win32
9286 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009293- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009294 and INF. float("nan"), float("inf") and float("-inf") now work on
9295 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009296
Georg Brandl3ee81df2008-05-17 18:14:43 +00009297- Compiler now generates simpler and faster code for dictionary
9298 literals. The oparg for BUILD_MAP now indicates an estimated
9299 dictionary size. There is a new opcode, STORE_MAP, for adding
9300 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009334- Issue #1265: Fix a problem with sys.settrace, if the tracing
9335 function uses a generator expression when at the same time the
9336 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009337
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009338- sets and frozensets now have an isdisjoint() method.

9343
Georg Brandl21e99f42010-03-07 15:23:59 +00009344- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009345 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9346 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009347
Georg Brandl3ee81df2008-05-17 18:14:43 +00009348- Issue #1686386: Tuple's tp_repr did not take into account the
9349 possibility of having a self-referential tuple, which is possible
9350 from C code. Nor did object's tp_str consider that a type's tp_str
9351 could do something that could lead to an inifinite recursion.
9352 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9353 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009354
Georg Brandl3ee81df2008-05-17 18:14:43 +00009355- Issue #1164: It was possible to trigger deadlock when using the
9356 'print' statement to write to a file since the GIL was not released
9357 as needed. Now PyObject_Print() does the right thing along with
9358 various tp_print implementations of the built-in types and those in
9359 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009360
Georg Brandl3ee81df2008-05-17 18:14:43 +00009361- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00009368- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009369 PyObject_Call() never calling back out to Python code to trigger
9370 recursion depth updates/checks. Required the creation of a static
9371 RuntimeError instance in case normalizing an exception put the
9372 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00009399 "except E as target:". This is to provide forwards compatibility
9400 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009404- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00009407- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009408 setting a plain string, ie don't expand to single letter identifiers.
9409
Raymond Hettinger13936692007-04-11 18:40:58 +00009410- Request #1191699: Slices can now be pickled.

9420
Guido van Rossum143b5642007-03-23 04:58:42 +00009421- Bug #1683368: The object.__init__() and object.__new__() methods are
9422 now stricter in rejecting excess arguments. The only time when
9423 either allows excess arguments is when it is not overridden and the
9424 other one is. For backwards compatibility, when both are
9425 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009426 warning later). Also, type.__init__() insists on the same signature
9427 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009429- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9430 object to complex using its __complex__() method before falling back
9431 to the __float__() method. Therefore, the functions in the cmath
9432 module now can operate on objects that define a __complex__()
9433 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009451- Bug #1678647: write a newline after printing an exception in any
9452 case, even when converting the value to a string failed.
9453
Georg Brandl871f1bc2007-03-12 13:17:36 +00009454- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009455 its argument, if it exists. If not, it will work like before. This
9456 allows customizing the output of dir() in the presence of a
9457 __getattr__().

9467 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009468
Georg Brandlaa2321b2007-03-07 00:40:28 +00009469- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009470 makes the filenames the warning module prints much more sensible
9471 when a PYTHONSTARTUP file is used.

9485 sq_ass_slice instead of the sq_slice slot.
9486
Georg Brandl3ee81df2008-05-17 18:14:43 +00009487- When printing an unraisable error, don't print exceptions. before

Vinay Sajip8549ce32007-05-06 17:53:37 +00009995- Patch #1676823: Added create_connection() to socket.py, which may be

10100 returned string up to the first NUL character.

10111
Georg Brandl3ee81df2008-05-17 18:14:43 +000010112- unittest now verifies more of its assumptions. In particular,
10113 TestCase and TestSuite subclasses (not instances) are no longer
10114 accepted in TestSuite.addTest(). This should cause no

10116 -- the failure just occurred later, with a more cumbersome
10117 exception.

10385 the first chunk fed to the decoder started with a BOM, but was
10386 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010387
Georg Brandl3ee81df2008-05-17 18:14:43 +000010388- The implementation of UnicodeError objects has been simplified

Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010398 that the SMTP.starttls() caller no longer needs to call ehlo()
10399 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010400 does not claim to support starttls. Adds the
10401 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010444- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010445 works as expected. ``mmap.find`` also takes an optional ``end``

10482 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10483 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +000010500 time so that opening a database previously created with the DB_DUP
10501 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10502 opens. Specifically: dictionary assignment to a DB object will
10503 replace all values for a given key when the database allows
10504 duplicate values. DB users should use DB.put(k, v) when they want
10505 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010506

10512 characters with ASCII value less than 32. Also, it correctly quotes
10513 dots only if they occur on a single line, as opposed to the previous
10514 behavior of quoting dots if they are the second character of any
10515 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010516

10844
Georg Brandl3ee81df2008-05-17 18:14:43 +000010845- Unified naming convention for free lists and their limits. All free
10846 lists in Object/ are named ``free_list``, the counter ``numfree``
10847 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10848 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010849
Georg Brandl3ee81df2008-05-17 18:14:43 +000010850- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10851 to ``PyTuple_SetItem``, it can be used to populate a brand new
10852 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010853
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010854- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010855
Georg Brandl3ee81df2008-05-17 18:14:43 +000010856- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10857 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10858 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010859
10860- Patch #1720595: add T_BOOL to the range of structmember types.
10861
10862- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10863 ``PyFloat_GetInfo()`` to the float API.
10864
Georg Brandl3ee81df2008-05-17 18:14:43 +000010865- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10866 of w# format code incorrectly truncated the length to an int, even
10867 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10868 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010869
Georg Brandl3ee81df2008-05-17 18:14:43 +000010870- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10871 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010872
Georg Brandl3ee81df2008-05-17 18:14:43 +000010873- PEP 3123: Provide forward compatibility with Python 3.0, while
10874 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10875 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010876
Georg Brandl3ee81df2008-05-17 18:14:43 +000010877- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10878 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010879
10880- Patch #1733960: Allow T_LONGLONG to accept ints.
10881
10882- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10883
Christian Heimes000a0742008-01-03 22:16:32 +000010884- Added a new API function ``PyImport_ImportModuleNoBlock``.
10885
Georg Brandl6caad7d2008-01-26 14:19:22 +000010886- Bug #1637022: Prefix AST symbols with _Py_.
10887
10888- Fix some leftovers from the conversion from int to Py_ssize_t
10889 (relevant to strings and sequences of more than 2**31 items).
10890
10891- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10892 outside of pystate.c and should not be necessary.
10893
Georg Brandl3ee81df2008-05-17 18:14:43 +000010894- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10895 absolute imports. In earlier versions they might have used relative
10896 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010897
Georg Brandl3ee81df2008-05-17 18:14:43 +000010898- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10899 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010900
Georg Brandl3ee81df2008-05-17 18:14:43 +000010901- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10902 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010907- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10908 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10909 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10910 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010911
Georg Brandl3ee81df2008-05-17 18:14:43 +000010912- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10913 _CRT_NONSTDC_NO_DEPRECATE.
Martin v. Löwis2607e6c2006-11-21 18:20:25 +000010914

Brett Cannon791d56f2007-05-31 19:40:42 +000010922- buildtools now raises a DeprecationWarning.
10923
Georg Brandl3ee81df2008-05-17 18:14:43 +000010924- Removed the macfs module. It had been deprecated since Python 2.5.
10925 This lead to the deprecation of macostools.touched() as it relied
10926 solely on macfs and was a no-op under OS X.
