1212
1213- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1214 and later systems as is currently done for Python 3.x installers.
1215 For 2.7.7 only, we will provide three installers:
1216 the legacy deprecated 10.3+ 32-bit-only format;
1217 the newer 10.5+ 32-bit-only format;
1218 and the unchanged 10.6+ 64-/32-bit format.
1219 Although binary installers will no longer be available from
1220 python.org as of 2.7.8, it will still be possible to build from
1221 source on 10.3.9 and 10.4 systems if necessary.
1222 See Mac/BuildScript/README.txt for more information.

2604 32-bit-only installer Pythons on systems with Xcode 4 (currently
2605 OS X 10.8, 10.7, and optionally 10.6).
2606 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2607 * Since Xcode 4 removes ppc support, extension module builds now
2608 check for ppc compiler support and by default remove ppc and
2609 ppc64 archs when they are not available.
2610 * Extension module builds now revert to using system installed
2611 headers and libs (/usr and /System/Library) if the SDK used
2612 to build the interpreter is not installed or has moved.
2613 * Try to avoid building extension modules with deprecated
2614 and problematic Apple llvm-gcc compiler. If original compiler
2615 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003052- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003053 has left two versions of customize_compiler, the original in
3054 distutils.sysconfig and another copy in distutils.ccompiler, with some

3057 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01003059- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3060 Distutils-based packages with C extension modules may fail because
3061 Apple has removed gcc-4.2, the version used to build python.org
3062 64-bit/32-bit Pythons. If the user does not explicitly override
3063 the default C compiler by setting the CC environment variable,
3064 Distutils will now attempt to compile extension modules with clang
3065 if gcc-4.2 is required but not found. Also as a convenience, if
3066 the user does explicitly set CC, substitute its value as the default
3067 compiler in the Distutils LDSHARED configuration variable for OS X.
3068 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3069 SDK, neither of which are available in Xcode 4. This change does not
3070 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003320- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3321 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3322 interpreter process. This could cause failures in non-Distutils subprocesses
3323 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003324 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003325 deployment target only in the environment of each build subprocess. It is
3326 still possible to globally override the default by setting
3327 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3328 greater or equal to the default value, the value with which the interpreter
3329 was built.

3358 updating the check interval, so if the user decreases the check interval,
3359 the ticker doesn't have to wind down to zero from the old starting point
3360 before the new interval takes effect. And if the user increases the
3361 interval, it makes sure the new limit takes effect right away rather have an
3362 early task switch before recognizing the new interval.

4358
Raymond Hettinger20397532010-09-12 02:11:45 +00004359- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4360 This prevents user-created self-referencing ordered dictionaries from
4361 becoming permanently uncollectable GC garbage. The downside is that
4362 removing __del__ means that the internal doubly-linked list has to wait for
4363 GC collection rather than freeing memory immediately when the refcnt drops
4364 to zero.
4365

4369
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004370- Issue #9792: In case of connection failure, socket.create_connection()
4371 would swallow the exception and raise a new one, making it impossible
4372 to fetch the original errno, or to filter timeout errors. Now the
4373 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004822- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4823 start byte and the continuation byte(s) are now considered invalid, instead
4824 of the number of bytes specified by the start byte.
4825 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4826 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4827 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4828 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004836- Issue #8748: Fix two issues with comparisons between complex and integer
4837 objects. (1) The comparison could incorrectly return True in some cases
4838 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4839 (2) The comparison raised an OverflowError for large integers, leading
4840 to unpredictable exceptions when combining integers and complex objects

5224 with a non-empty format string. This is an effort to future-proof user
5225 code. If a derived class does not currently implement __format__ but later

Georg Brandlba83f822010-03-14 09:50:54 +00005721 file position when calling `truncate()`. It would previously change the file
5722 position to the given argument, which goes against the tradition of

5726 class used to represent files stored inside an archive. The new
5727 implementation is significantly faster and can be wrapped in a

5729 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5818-----------------
5819
Georg Brandlba83f822010-03-14 09:50:54 +00005820- The ``__complex__()`` method is now looked up on the class of instances to
5821 make it consistent with other special methods.

5825
Mark Dickinson1b34d252010-01-01 17:27:30 +00005826- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005827 DeprecationWarning when passed a float argument where an integer was expected.
5828 These functions and methods now raise TypeError instead. The majority of the
5829 effects of this change are in the extension modules, but some core functions
5830 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5831 and many unicode/str methods.

5846 least on IEEE 754 platforms), and in particular does not depend on the
5847 internal representation of a long.

5855
Georg Brandlba83f822010-03-14 09:50:54 +00005856 These executables now work properly with the arch(1) command: ``arch -ppc

5943 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5944 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5945 float arguments for integer format codes (other than 'L'): previously an
5946 attempt to pass a float resulted in a DeprecationWarning; now it gives a
5947 TypeError. For the 'L' format code (which previously had no warning) there is
5948 now a DeprecationWarning.

5997 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005998

6000 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00006012
Georg Brandlba83f822010-03-14 09:50:54 +00006013- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6014 decimal string that's guaranteed to round back to x under correct rounding
6015 (with round-half-to-even rounding mode). Previously it gave a string based on
6016 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6017 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6018 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006019
Georg Brandlba83f822010-03-14 09:50:54 +00006020- Issue #7117: On almost all platforms: float-to-string and string-to-float
6021 conversions within Python are now correctly rounded. Places these conversions
6022 occur include: str for floats and complex numbers; the float and complex
6023 constructors; old-style and new-style numeric formatting; serialization and
6024 deserialization of floats and complex numbers using marshal, pickle and json;
6025 parsing of float and imaginary literals in Python code; Decimal-to-float
6026 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006027
Georg Brandlba83f822010-03-14 09:50:54 +00006028 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6029 providing correctly-rounded strtod and dtoa C functions. This code is
6030 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6031 the C compiler. There may be a small number of platforms on which correct
6032 operation of this code cannot be guaranteed, so the code is not used: notably,
6033 this applies to platforms where the C double format is not IEEE 754 binary64,
6034 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6035 and Python's configure script is unable to determine how to change the FPU
6036 precision. On these platforms conversions use the platform strtod and dtoa,
6037 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006038
Georg Brandlba83f822010-03-14 09:50:54 +00006039- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6040 uses the correctly-rounded string <-> float conversions described above (when
6041 available), and so produces correctly rounded results that will display nicely
6042 under the float repr. There are two related small changes: (1) round now
6043 accepts any class with an ``__index__()`` method for its second argument (but
6044 no longer accepts floats for the second argument), and (2) an excessively
6045 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6046 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006176- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
6177 consistent with float("1e500") and interpretation of real and imaginary
6178 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00006187- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00006188
Georg Brandlba83f822010-03-14 09:50:54 +00006189 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
6190 (2) parsing of strings representing infinities and nans was locale aware; and
6191 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00006193- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6194 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6195 but with at least one decimal point and with a default precision
6196 of 12. Previously, the behavior the same but with a default precision of 6.
6197 This more closely matches ``str()``, and reduces surprises when adding
6198 alignment flags to the empty presentation type. This also affects the new
6199 complex.__format__ in the same way.
6200
6201- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
6202 classtype's, even if it was None. property now inserts the __doc__ into the

Antoine Pitrouf8387af2009-03-23 18:41:45 +00006263- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00006264 untrackable objects are not tracked by the garbage collector. This can reduce
6265 the size of collections and therefore the garbage collection overhead on

6273 internal representation of integers, for performance reasons. Base 2**30 is
6274 enabled by default on 64-bit machines. Add --enable-big-digits option to
6275 configure, which overrides the default. Add sys.long_info structseq to
6276 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00006423- On windows, ``os.chdir()`` given unicode was not working if

6425 this code path is really executed because I cannot move to such directory on
6426 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006428- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6429 element is temporarily replaced with an equivalent frozenset. But the
6430 eventual KeyError would always report the empty ``frozenset()`` as the missing
6431 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006451- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6452 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6453 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6454 of using the replace error handler in PyUnicode_DecodeUTF8().
6455
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006456- Issue #3739: The unicode-internal encoder now reports the number of characters

6458
Georg Brandlba83f822010-03-14 09:50:54 +00006459- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6460 allocator will be automatically disabled when running under Valgrind. This
6461 gives improved memory leak detection when running under Valgrind, while taking
6462 advantage of pymalloc at other times.

7653 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7654 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007851- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7852
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007853- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7854 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7855 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7856 ``printf`` function, whereas PyString_FromFormat has an independent
7857 implementation and uses "%zd" on all platforms for size_t values.
7858 This makes a difference on win64, where ``printf`` needs "%Id" to display
7859 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007861- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7865 object; previously an int would be returned for small values. the __long__
7866 method is allowed to return either an int or a long, but the behaviour of
7867 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007876 was correctly parsed but parsing of subsequent arguments failed.
7877
Vinay Sajip35e3b032008-09-01 14:33:59 +00007878- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007879 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7880 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7881 when given a tuple of classes as second argument, were looking up
7882 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7883 type object.

8028-----------------
8029
Guido van Rossumf8402962008-08-20 15:01:50 +00008030- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8031 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8032 extensions do not automatically benefit from the class attribute
8033 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8034 to their tp_flags field if they care. This is a backwards
8035 compatibility feature; in 3.0, all types will use the cache by
8036 default.
8037
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008038- Keyword arguments can now follow starred arguments. (``f(a, *args,
8039 keyword=23)`` is now valid syntax.)
8040
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008041- ctypes function pointers that are COM methods have a boolean True
8042 value again.

8053
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008054- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8055 (64bit Unix, for example), unichr() would truncate its argument and return
8056 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Antoine Pitrou92f82162008-07-25 22:22:08 +00008063- Issue #1819: function calls with several named parameters are now on
8064 average 35% faster (as measured by pybench).
8065
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008066- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8067 the python debugger steps into a class statement: the free variables (local
8068 variables defined in an outer scope) would be deleted from the outer scope.
8069
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008070- Issue #2620: Overflow checking when allocating or reallocating memory
8071 was not always being done properly in some python types and extension
8072 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8073 all been updated to perform better checks and places in the code that
8074 would previously leak memory on the error path when such an allocation
8075 failed have been fixed.

8083 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8084
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008085- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8086 version reported by these tools does not necessarily follow the python
8087 version numbering scheme, so the module is less strict when parsing it.
8088
Nick Coghlanf70385a2008-08-18 12:42:46 +00008089- Issue #2235: Added Py3k warnings for types which will become unhashable
8090 under the stricter __hash__ inheritance rules in 3.0. Several types
8091 which did not meet the rules for hash invariants and were already
8092 unhashable in 3.0 have now been explicitly flagged as unhashable in
8093 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8094 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8095
Brett Cannon88f801d2008-08-18 00:46:22 +00008096- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

8122 regular expression.
8123
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008124- Issue #3476: binary buffered reading through the new "io" library is now
8125 thread-safe.

Brett Cannonbf3157b2008-08-14 05:00:03 +00008127- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8128 since mimetools itself is deprecated. Because modules are cached, all
8129 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8130
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008131- Issue #3134: shutil referenced undefined WindowsError symbol.

8140 a MemoryError rather than silently stop the iteration.
8141
Guido van Rossum59ce9012008-08-09 14:55:34 +00008142- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8143 to _sre.compile() will now be rejected. This should not affect anybody
8144 since the re.compile() function never generates invalid re-bytecode.
8145
Skip Montanaroa032bf42008-08-08 22:52:51 +00008146- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8147 upon first access it can be automatically initialized from the csv file if
8148 it wasn't initialized during instantiation.
8149
Brett Cannon3aa2a492008-08-06 22:28:09 +00008150- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8151 the reload() built-in has been removed.
8152
Brett Cannon7e30b672008-08-04 21:52:25 +00008153- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008154 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00008165 asking for a specific length. This problem only affected files opened
8166 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008191- Issue #3394: zipfile.writestr sets external attributes when passed a
8192 file name rather than a ZipInfo instance, so files are extracted with
8193 mode 0600 rather than 000 under Unix.
8194
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008195- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

8208 interaction with the tp_hash slot (added in 2.6b2) are now documented
8209
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008210- Issue #643841: The language reference now provides more detailed
8211 coverage of the lookup process for special methods. The disclaimers
8212 regarding lack of coverage of new-style classes have also been
8213 removed, since the coverage is now fairly reasonable.

8217================================
8218
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008219*Release date: 17-Jul-2008*
8220
Raymond Hettingere3ae6552008-06-20 04:18:15 +00008221Core and Builtins
8222-----------------
8223
Georg Brandl3e483f62008-07-16 22:57:41 +00008224- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8225 its methods now allow for items objects that can be converted to
8226 an integer using operator.index().
8227
Mark Dickinson64b7e502008-07-16 09:40:03 +00008228- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8229 produced a ValueError instead of giving the correct float.
8230
Eric Smitha5fa5a22008-07-16 00:11:49 +00008231- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8232 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8233
Mark Dickinson7103aa42008-07-15 19:08:33 +00008234- Issue #3008: the float type has a new instance method 'float.hex'
8235 and a new class method 'float.fromhex' to convert floating-point
8236 numbers to and from hexadecimal strings, respectively.
8237
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008238- Issue #2235: __hash__ is once again inherited by default. To allow
8239 collections.Hashable to remain meaningful in the presence of the
8240 default hash implementation (object.__hash__), it is now possible
8241 to explicit block inheritance of hash by setting __hash__=None at
8242 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8243 level.
8244
Nick Coghlanb028f502008-07-13 14:52:36 +00008245- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8246 the parent module cannot be found while performing an absolute import.
8247 This means that an incorrectly defined __package__ attribute will
8248 now only prevent relative imports in that module rather than causing
8249 all imports from that module to fail.
8250
Nick Coghlan14ff9942008-07-08 14:21:42 +00008251- Issue #2517: Allow unicode messages in Exceptions again by correctly
8252 bypassing the instance dictionary when looking up __unicode__ on
8253 new-style classes.
8254
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008255- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8256 set to a custom object whose write() method happens to install
8257 another file in sys.stdout.
8258
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008259- Issue #3088: Corrected a race condition in classes derived from
8260 threading.local: the first member set by a thread could be saved in
8261 another thread's dictionary.
8262
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008263- Issue #3004: Minor change to slice.indices(): the start and stop
8264 arguments are now treated identically, making the behaviour easier
8265 to describe and understand. For example, slice(None, -10,
8266 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8267 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8268 10, -1).
8269
Georg Brandl278fc502008-07-19 12:46:12 +00008270- Issue #3219: Calling a function with repeated keyword arguments,
8271 f(a=2, a=23), would not cause a syntax error. This was a regression
8272 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008273
Georg Brandl278fc502008-07-19 12:46:12 +00008274- Issue #2862: Make int and float freelist management consistent with
8275 other freelists. Changes their CompactFreeList apis into
8276 ClearFreeList apis and calls them via gc.collect().

8282 api functions without holding the GIL, which could lead to a fatal
8283 error when they failed.
8284
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008285- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00008293- Issue #3125: Remove copy_reg in multiprocessing and replace it with
8294 ForkingPickler.register() to resolve conflict with ctypes.
8295
Vinay Sajip51e65192008-07-18 09:01:10 +00008296- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00008298- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8299 a valid dlerror() message.
8300
Thomas Heller2bad6572008-07-15 17:19:50 +00008301- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8302 incomplete structure was created.
8303

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008308- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008309
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008310- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8311 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008312 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008313 content-length. The problem had been corrected in the 2.4 branch, but never
8314 merged into trunk.
8315

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008329- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8330 handling is now the same as that of other special attributes like __name__).
8331
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008332- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
8333 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008720 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008721
8722 This is controlled by the configure argument ``--with-universal-archs``:
8723
8724 - ``--with-universal-archs=all``: install 4-way universal
8725
8726 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8727
8728 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8729
8730 This option should be used in combination with ``--enable-universalsdk=``.
8731
8732 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 +00008781- Issue #1631171: Re-implement the 'warnings' module in C (the
8782 original Python code has been kept as backup). This will allow for
8783 using the 'warning's machinery in such places as the parser where
8784 use of pure Python code is not possible. Both the ``showarning()``
8785 and ``formatwarning()`` gain an optional 'line' argument which is
8786 not called by default for backwards-compatibility reasons. Setting
8787 ``warnings.showwarning()`` to an implementation that lacks support
8788 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008851- Issue #2550: The approach used by client/server code for obtaining
8852 ports to listen on in network-oriented tests has been refined in an
8853 effort to facilitate running multiple instances of the entire
8854 regression test suite in parallel without issue.
8855 test_support.bind_port() has been fixed such that it will always
8856 return a unique port -- which wasn't always the case with the
8857 previous implementation, especially if socket options had been set
8858 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8859 new implementation of bind_port() will actually raise an exception
8860 if it is passed an AF_INET/SOCK_STREAM socket with either the
8861 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8862 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8863 the socket it's been passed. This currently only applies to
8864 Windows. This option prevents any other sockets from binding to the
8865 host/port we've bound to, thus removing the possibility of the
8866 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8867 when a second SOCK_STREAM socket binds and accepts to a host/port
8868 that's already been bound by another socket. The optional preferred
8869 port parameter to bind_port() has been removed. Under no
8870 circumstances should tests be hard coding ports!
8871
8872 test_support.find_unused_port() has also been introduced, which will
8873 pass a temporary socket object to bind_port() in order to obtain an
8874 unused port. The temporary socket object is then closed and
8875 deleted, and the port is returned. This method should only be used
8876 for obtaining an unused port in order to pass to an external program
8877 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8878 a parameter to a server-oriented class that doesn't give you direct
8879 access to the underlying socket used.
8880
8881 Finally, test_support.HOST has been introduced, which should be used
8882 for the host argument of any relevant socket calls (i.e. bind and
8883 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008884
8885 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008886 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008887 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8888 test_asynchat and test_socket_ssl.
8889
Georg Brandl3ee81df2008-05-17 18:14:43 +00008890 It is now possible for multiple instances of the regression test

Facundo Batistafc2d0102008-02-23 12:01:13 +00009169
Eric Smitha73fbe72008-02-23 03:09:44 +00009170- Added the future_builtins module, which contains hex() and oct().
9171 These are the PEP 3127 version of these functions, designed to be
9172 compatible with the hex() and oct() builtins from Python 3.0. They
9173 differ slightly in their output formats from the existing, unchanged
9174 Python 2.6 builtins. The expected usage of the future_builtins
9175 module is:
9176 from future_builtins import hex, oct
9177
Eric Smith7ef40bf2008-02-20 23:34:22 +00009178- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9179 exponents for exponents with absolute value < 100. Follows C99
9180 standard. This is a change on Windows, which would use 3 digits.
9181 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9182 so that any alterations it does to the resulting string will be
9183 available in stringlib/formatter.h (for float.__format__).
9184
Eric Smith5a3c1352008-02-19 13:21:56 +00009185- Implemented PEP 3101, Advanced String Formatting. This adds a new
9186 builtin format(); a format() method for str and unicode; a
9187 __format__() method to object, str, unicode, int, long, float, and
9188 datetime; the class string.Formatter; and the C API
9189 PyObject_Format().
9190
Georg Brandl3ee81df2008-05-17 18:14:43 +00009191- Fixed several potential crashes, all caused by specially crafted
9192 __del__ methods exploiting objects in temporarily inconsistent
9193 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009194
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009195- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009196 prevent a possible crash: an Abstract Base Class would try to access
9197 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009198

Georg Brandl3ee81df2008-05-17 18:14:43 +00009202- Clear all free lists during a gc.collect() of the highest generation
9203 in order to allow pymalloc to free more arenas. Python may give back
9204 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009205
Georg Brandl3ee81df2008-05-17 18:14:43 +00009206- Issue #2045: Fix an infinite recursion triggered when printing a
9207 subclass of collections.defaultdict, if its default_factory is set
9208 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00009210- Fixed a minor memory leak in dictobject.c. The content of the free
9211 list was not freed on interpreter shutdown.
9212
Georg Brandl21e99f42010-03-07 15:23:59 +00009213- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009214 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009215
Georg Brandl3ee81df2008-05-17 18:14:43 +00009216- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9217 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009218 to compact the internal free lists of pre-allocted ints and floats.
9219
Georg Brandl3ee81df2008-05-17 18:14:43 +00009220- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9221 calls. Python expected the return type int but the fork familie
9222 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009236- Patch #1473257: generator objects gain a gi_code attribute. This is
9237 the same object as the func_code attribute of the function that
9238 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009239
Georg Brandl3ee81df2008-05-17 18:14:43 +00009240- Issue #1920: "while 0" statements were completely removed by the
9241 compiler, even in the presence of an "else" clause, which is
9242 supposed to be run when the condition is false. Now the compiler
9243 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009244
Guido van Rossumeead05f2008-01-24 18:21:02 +00009245- A few crashers fixed: weakref_in_del.py (issue #1377858);
9246 loosing_dict_ref.py (issue #1303614, test67.py);
9247 borrowed_ref_[34].py (not in tracker).
9248
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009249- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009250 suppressed while an extension is loaded by calling SetErrorMode in
9251 dynload_win.c. The error is still reported properly.
9252
Georg Brandl3ee81df2008-05-17 18:14:43 +00009253- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009254 several extension methods and modules do not work without unicode
9255 support.
9256
Georg Brandl26543b12008-01-21 18:36:51 +00009257- Issue #1882: when compiling code from a string, encoding cookies in the

9261
Georg Brandl6caad7d2008-01-26 14:19:22 +00009262- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009263 added.
9264
Christian Heimesc94e2b52008-01-14 04:13:37 +00009265- sys.float_info / PyFloat_GetInfo: The floating point information
9266 object was converted from a dict to a specialized structseq object.
9267
Georg Brandl3ee81df2008-05-17 18:14:43 +00009268- Patch #1816: Added sys.flags structseq. It exposes the status of
9269 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009270
Georg Brandl3ee81df2008-05-17 18:14:43 +00009271- Objects/structseq.c: Implemented new structseq representation. The
9272 patch makes structseqs (e.g. the return value of os.stat) more
9273 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009274
Georg Brandl3ee81df2008-05-17 18:14:43 +00009275- Patch #1700288: added a type attribute cache that caches method
9276 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009277
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009278- Bug #1776: __import__() no longer accepts filenames on any platform.

9284 envvar and sys.dont_write_bytecode attribute. All these can be set
9285 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009286
Georg Brandl3ee81df2008-05-17 18:14:43 +00009287- Improve some exception messages when Windows fails to load an
9288 extension module. Now we get for example '%1 is not a valid Win32
9289 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009296- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009297 and INF. float("nan"), float("inf") and float("-inf") now work on
9298 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009299
Georg Brandl3ee81df2008-05-17 18:14:43 +00009300- Compiler now generates simpler and faster code for dictionary
9301 literals. The oparg for BUILD_MAP now indicates an estimated
9302 dictionary size. There is a new opcode, STORE_MAP, for adding
9303 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009337- Issue #1265: Fix a problem with sys.settrace, if the tracing
9338 function uses a generator expression when at the same time the
9339 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009340
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009341- sets and frozensets now have an isdisjoint() method.
9342

9346
Georg Brandl21e99f42010-03-07 15:23:59 +00009347- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009348 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9349 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009350
Georg Brandl3ee81df2008-05-17 18:14:43 +00009351- Issue #1686386: Tuple's tp_repr did not take into account the
9352 possibility of having a self-referential tuple, which is possible
9353 from C code. Nor did object's tp_str consider that a type's tp_str
9354 could do something that could lead to an inifinite recursion.
9355 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9356 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009357
Georg Brandl3ee81df2008-05-17 18:14:43 +00009358- Issue #1164: It was possible to trigger deadlock when using the
9359 'print' statement to write to a file since the GIL was not released
9360 as needed. Now PyObject_Print() does the right thing along with
9361 various tp_print implementations of the built-in types and those in
9362 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009363
Georg Brandl3ee81df2008-05-17 18:14:43 +00009364- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00009371- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009372 PyObject_Call() never calling back out to Python code to trigger
9373 recursion depth updates/checks. Required the creation of a static
9374 RuntimeError instance in case normalizing an exception put the
9375 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00009402 "except E as target:". This is to provide forwards compatibility
9403 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009407- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009408 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009410- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009411 setting a plain string, ie don't expand to single letter identifiers.
9412
Raymond Hettinger13936692007-04-11 18:40:58 +00009413- Request #1191699: Slices can now be pickled.

9423
Guido van Rossum143b5642007-03-23 04:58:42 +00009424- Bug #1683368: The object.__init__() and object.__new__() methods are
9425 now stricter in rejecting excess arguments. The only time when
9426 either allows excess arguments is when it is not overridden and the
9427 other one is. For backwards compatibility, when both are
9428 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009429 warning later). Also, type.__init__() insists on the same signature
9430 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009432- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9433 object to complex using its __complex__() method before falling back
9434 to the __float__() method. Therefore, the functions in the cmath
9435 module now can operate on objects that define a __complex__()
9436 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009454- Bug #1678647: write a newline after printing an exception in any
9455 case, even when converting the value to a string failed.
9456
Georg Brandl871f1bc2007-03-12 13:17:36 +00009457- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009458 its argument, if it exists. If not, it will work like before. This
9459 allows customizing the output of dir() in the presence of a
9460 __getattr__().

9469 parthensized forms. This means complex(repr(x)) now works instead of
9470 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009471
Georg Brandlaa2321b2007-03-07 00:40:28 +00009472- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009473 makes the filenames the warning module prints much more sensible
9474 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009475

9488 sq_ass_slice instead of the sq_slice slot.
9489
Georg Brandl3ee81df2008-05-17 18:14:43 +00009490- When printing an unraisable error, don't print exceptions. before

Vinay Sajip8549ce32007-05-06 17:53:37 +00009998- Patch #1676823: Added create_connection() to socket.py, which may be

10103 returned string up to the first NUL character.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010115- unittest now verifies more of its assumptions. In particular,
10116 TestCase and TestSuite subclasses (not instances) are no longer
10117 accepted in TestSuite.addTest(). This should cause no

10119 -- the failure just occurred later, with a more cumbersome
10120 exception.

10388 the first chunk fed to the decoder started with a BOM, but was
10389 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010390
Georg Brandl3ee81df2008-05-17 18:14:43 +000010391- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010400- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010401 that the SMTP.starttls() caller no longer needs to call ehlo()
10402 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010403 does not claim to support starttls. Adds the
10404 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010447- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010448 works as expected. ``mmap.find`` also takes an optional ``end``

10485 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10486 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +000010503 time so that opening a database previously created with the DB_DUP
10504 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10505 opens. Specifically: dictionary assignment to a DB object will
10506 replace all values for a given key when the database allows
10507 duplicate values. DB users should use DB.put(k, v) when they want
10508 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010509

10515 characters with ASCII value less than 32. Also, it correctly quotes
10516 dots only if they occur on a single line, as opposed to the previous
10517 behavior of quoting dots if they are the second character of any
10518 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010519

10847
Georg Brandl3ee81df2008-05-17 18:14:43 +000010848- Unified naming convention for free lists and their limits. All free
10849 lists in Object/ are named ``free_list``, the counter ``numfree``
10850 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10851 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010852
Georg Brandl3ee81df2008-05-17 18:14:43 +000010853- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10854 to ``PyTuple_SetItem``, it can be used to populate a brand new
10855 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010856
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010857- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010858
Georg Brandl3ee81df2008-05-17 18:14:43 +000010859- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10860 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10861 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010862
10863- Patch #1720595: add T_BOOL to the range of structmember types.
10864
10865- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10866 ``PyFloat_GetInfo()`` to the float API.
10867
Georg Brandl3ee81df2008-05-17 18:14:43 +000010868- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10869 of w# format code incorrectly truncated the length to an int, even
10870 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10871 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010872
Georg Brandl3ee81df2008-05-17 18:14:43 +000010873- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10874 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010875
Georg Brandl3ee81df2008-05-17 18:14:43 +000010876- PEP 3123: Provide forward compatibility with Python 3.0, while
10877 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10878 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010879
Georg Brandl3ee81df2008-05-17 18:14:43 +000010880- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10881 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010882
10883- Patch #1733960: Allow T_LONGLONG to accept ints.
10884
10885- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10886
Christian Heimes000a0742008-01-03 22:16:32 +000010887- Added a new API function ``PyImport_ImportModuleNoBlock``.
10888
Georg Brandl6caad7d2008-01-26 14:19:22 +000010889- Bug #1637022: Prefix AST symbols with _Py_.
10890
10891- Fix some leftovers from the conversion from int to Py_ssize_t
10892 (relevant to strings and sequences of more than 2**31 items).
10893
10894- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10895 outside of pystate.c and should not be necessary.
10896
Georg Brandl3ee81df2008-05-17 18:14:43 +000010897- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10898 absolute imports. In earlier versions they might have used relative
10899 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010900
Georg Brandl3ee81df2008-05-17 18:14:43 +000010901- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10902 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010903
Georg Brandl3ee81df2008-05-17 18:14:43 +000010904- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10905 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010910- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10911 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10912 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10913 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010914
Georg Brandl3ee81df2008-05-17 18:14:43 +000010915- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10916 _CRT_NONSTDC_NO_DEPRECATE.
Martin v. Löwis2607e6c2006-11-21 18:20:25 +000010917

Brett Cannon791d56f2007-05-31 19:40:42 +000010925- buildtools now raises a DeprecationWarning.
10926
Georg Brandl3ee81df2008-05-17 18:14:43 +000010927- Removed the macfs module. It had been deprecated since Python 2.5.
10928 This lead to the deprecation of macostools.touched() as it relied
10929 solely on macfs and was a no-op under OS X.
