298 This prevents user-created self-referencing ordered dictionaries from
299 becoming permanently uncollectable GC garbage. The downside is that
300 removing __del__ means that the internal doubly-linked list has to wait for
301 GC collection rather than freeing memory immediately when the refcnt drops
302 to zero.

307
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000308- Issue #9792: In case of connection failure, socket.create_connection()

310 to fetch the original errno, or to filter timeout errors. Now the

761 start byte and the continuation byte(s) are now considered invalid, instead
762 of the number of bytes specified by the start byte.
763 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
764 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
765 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

775 objects. (1) The comparison could incorrectly return True in some cases
776 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000918- Issue #1533: Fix inconsistency in range function argument processing: any
919 non-float non-integer argument is now converted to an integer (if possible)
920 using its __int__ method. Previously, only small arguments were treated this
921 way; larger arguments (those whose __int__ was outside the range of a C long)
922 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +0000930 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000931 benefit compared to the dynamic memory allocation fallback. Patch by

973 operation raises multiple signals and more than one of those signals is
974 trapped, the specification determines the order in which the signals should be
975 handled. In many cases this order wasn't being followed, leading to the wrong
976 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +0000977

Georg Brandlfee0f442010-05-22 21:26:21 +00001161- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1162 with a non-empty format string. This is an effort to future-proof user
1163 code. If a derived class does not currently implement __format__ but later
1164 adds its own __format__, it would most likely break user code that had
1165 supplied a format string. This will be changed to a DeprecationWaring in
1166 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001199- Issue #8257: The Decimal construct now accepts a float instance directly,
1200 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001201
1202 >>> Decimal(1.1)
1203 Decimal('1.100000000000000088817841970012523233890533447265625')
1204
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001205- collections.Counter() now supports a subtract() method.
1206
Georg Brandlfee0f442010-05-22 21:26:21 +00001207- The functools module now has a total_ordering() class decorator to simplify
1208 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00001216- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1217 InvalidOperation instead of returning False. (Comparisons involving a quiet
1218 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1219 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001220
Georg Brandlfee0f442010-05-22 21:26:21 +00001221- Issue #2531: Comparison operations between floats and Decimal instances now
1222 return a result based on the numeric values of the operands; previously they
1223 returned an arbitrary result based on the relative ordering of id(float) and
1224 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001225
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001226- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001227 argument `-` which tells it to read files to compile from stdin. Each line is
1228 read on demand and the named file is compiled immediately. (Original patch by
1229 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001238- Comparisons using one of <, <=, >, >= between a complex instance and a
1239 Fractions instance now raise TypeError instead of returning True/False. This
1240 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1241 <=> complex, and complex <=> complex comparisons.

1350 the set of integer codes for which it was used differed between native packing
1351 and standard packing.)

1613 including:
Mark Dickinson8efef5c2010-01-12 22:23:56 +00001614
Georg Brandlba83f822010-03-14 09:50:54 +00001615 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
1616 strings,
1617 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1618 numeric strings corresponding to subnormal values,
1619 (3) a memory leak for some values large enough to cause overflow, and
1620 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00001659 file position when calling `truncate()`. It would previously change the file
1660 position to the given argument, which goes against the tradition of

1755Core and Builtins
1756-----------------
1757
Georg Brandlba83f822010-03-14 09:50:54 +00001758- The ``__complex__()`` method is now looked up on the class of instances to
1759 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001761- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1762 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1763
Mark Dickinson1b34d252010-01-01 17:27:30 +00001764- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001765 DeprecationWarning when passed a float argument where an integer was expected.
1766 These functions and methods now raise TypeError instead. The majority of the
1767 effects of this change are in the extension modules, but some core functions
1768 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1769 and many unicode/str methods.

1780 used to drop the time part of the result.
1781
Georg Brandlba83f822010-03-14 09:50:54 +00001782- Issue #1811: Improve accuracy and cross-platform consistency for true division
1783 of integers: the result of a/b is now correctly rounded for ints a and b (at
1784 least on IEEE 754 platforms), and in particular does not depend on the
1785 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001792 executables on OSX.
1793
Georg Brandlba83f822010-03-14 09:50:54 +00001794 These executables now work properly with the arch(1) command: ``arch -ppc
1795 python`` will start a universal binary version of python in PPC mode (unlike
1796 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001952- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1953 decimal string that's guaranteed to round back to x under correct rounding
1954 (with round-half-to-even rounding mode). Previously it gave a string based on
1955 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1956 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1957 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001958
Georg Brandlba83f822010-03-14 09:50:54 +00001959- Issue #7117: On almost all platforms: float-to-string and string-to-float
1960 conversions within Python are now correctly rounded. Places these conversions
1961 occur include: str for floats and complex numbers; the float and complex
1962 constructors; old-style and new-style numeric formatting; serialization and
1963 deserialization of floats and complex numbers using marshal, pickle and json;
1964 parsing of float and imaginary literals in Python code; Decimal-to-float
1965 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001966
Georg Brandlba83f822010-03-14 09:50:54 +00001967 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1968 providing correctly-rounded strtod and dtoa C functions. This code is
1969 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1970 the C compiler. There may be a small number of platforms on which correct
1971 operation of this code cannot be guaranteed, so the code is not used: notably,
1972 this applies to platforms where the C double format is not IEEE 754 binary64,
1973 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1974 and Python's configure script is unable to determine how to change the FPU
1975 precision. On these platforms conversions use the platform strtod and dtoa,
1976 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001978- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1979 uses the correctly-rounded string <-> float conversions described above (when
1980 available), and so produces correctly rounded results that will display nicely
1981 under the float repr. There are two related small changes: (1) round now
1982 accepts any class with an ``__index__()`` method for its second argument (but
1983 no longer accepts floats for the second argument), and (2) an excessively
1984 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1985 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002128 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2129 (2) parsing of strings representing infinities and nans was locale aware; and
2130 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002132- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2133 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2134 but with at least one decimal point and with a default precision
2135 of 12. Previously, the behavior the same but with a default precision of 6.
2136 This more closely matches ``str()``, and reduces surprises when adding
2137 alignment flags to the empty presentation type. This also affects the new
2138 complex.__format__ in the same way.
2139
2140- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002203 untrackable objects are not tracked by the garbage collector. This can reduce

2212 internal representation of integers, for performance reasons. Base 2**30 is
2213 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00002321- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2322 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2323 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002326- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2335
Georg Brandlba83f822010-03-14 09:50:54 +00002336- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2337 file objects with closefd=False. The file descriptor is still kept open but
2338 the file object behaves like a closed file. The ``FileIO`` object also got a
2339 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00002362- On windows, ``os.chdir()`` given unicode was not working if

2364 this code path is really executed because I cannot move to such directory on
2365 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002367- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2368 element is temporarily replaced with an equivalent frozenset. But the
2369 eventual KeyError would always report the empty ``frozenset()`` as the missing
2370 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002390- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2391 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2392 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2393 of using the replace error handler in PyUnicode_DecodeUTF8().
2394
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002395- Issue #3739: The unicode-internal encoder now reports the number of characters

2397
Georg Brandlba83f822010-03-14 09:50:54 +00002398- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2399 allocator will be automatically disabled when running under Valgrind. This
2400 gives improved memory leak detection when running under Valgrind, while taking
2401 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003766- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3767
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003768- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3769 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3770 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3771 ``printf`` function, whereas PyString_FromFormat has an independent
3772 implementation and uses "%zd" on all platforms for size_t values.
3773 This makes a difference on win64, where ``printf`` needs "%Id" to display
3774 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003776- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3780 object; previously an int would be returned for small values. the __long__
3781 method is allowed to return either an int or a long, but the behaviour of
3782 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003791 was correctly parsed but parsing of subsequent arguments failed.
3792
Vinay Sajip35e3b032008-09-01 14:33:59 +00003793- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003794 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3795 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3796 when given a tuple of classes as second argument, were looking up
3797 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3798 type object.

3943-----------------
3944
Guido van Rossumf8402962008-08-20 15:01:50 +00003945- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3946 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3947 extensions do not automatically benefit from the class attribute
3948 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3949 to their tp_flags field if they care. This is a backwards
3950 compatibility feature; in 3.0, all types will use the cache by
3951 default.
3952
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003953- Keyword arguments can now follow starred arguments. (``f(a, *args,
3954 keyword=23)`` is now valid syntax.)
3955
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003956- ctypes function pointers that are COM methods have a boolean True
3957 value again.

3967 ValueError consistently across platforms.
3968
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003969- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3970 (64bit Unix, for example), unichr() would truncate its argument and return
3971 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00003973- Apply security patches from Apple.
3974
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003975- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00003978- Issue #1819: function calls with several named parameters are now on
3979 average 35% faster (as measured by pybench).
3980
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003981- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3982 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00003985- Issue #2620: Overflow checking when allocating or reallocating memory
3986 was not always being done properly in some python types and extension
3987 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3988 all been updated to perform better checks and places in the code that
3989 would previously leak memory on the error path when such an allocation
3990 failed have been fixed.

3998 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3999
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004000- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4001 version reported by these tools does not necessarily follow the python
4002 version numbering scheme, so the module is less strict when parsing it.
4003
Nick Coghlanf70385a2008-08-18 12:42:46 +00004004- Issue #2235: Added Py3k warnings for types which will become unhashable
4005 under the stricter __hash__ inheritance rules in 3.0. Several types
4006 which did not meet the rules for hash invariants and were already
4007 unhashable in 3.0 have now been explicitly flagged as unhashable in
4008 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4009 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4010
Brett Cannon88f801d2008-08-18 00:46:22 +00004011- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4043 since mimetools itself is deprecated. Because modules are cached, all
4044 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4045

4055 a MemoryError rather than silently stop the iteration.
4056
Guido van Rossum59ce9012008-08-09 14:55:34 +00004057- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4058 to _sre.compile() will now be rejected. This should not affect anybody
4059 since the re.compile() function never generates invalid re-bytecode.
4060
Skip Montanaroa032bf42008-08-08 22:52:51 +00004061- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4062 upon first access it can be automatically initialized from the csv file if
4063 it wasn't initialized during instantiation.
4064
Brett Cannon3aa2a492008-08-06 22:28:09 +00004065- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4066 the reload() built-in has been removed.
4067
Brett Cannon7e30b672008-08-04 21:52:25 +00004068- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004069 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4077 raised an AttributeError.
4078

Antoine Pitroude781a42008-08-09 12:43:23 +00004080 asking for a specific length. This problem only affected files opened
4081 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004106- Issue #3394: zipfile.writestr sets external attributes when passed a
4107 file name rather than a ZipInfo instance, so files are extracted with
4108 mode 0600 rather than 000 under Unix.
4109
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004110- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4111 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00004122- Issue #2235: the C API function PyObject_HashNotImplemented and its
4123 interaction with the tp_hash slot (added in 2.6b2) are now documented
4124
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004125- Issue #643841: The language reference now provides more detailed
4126 coverage of the lookup process for special methods. The disclaimers
4127 regarding lack of coverage of new-style classes have also been
4128 removed, since the coverage is now fairly reasonable.

4132================================
4133
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004134*Release date: 17-Jul-2008*
4135
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004136Core and Builtins
4137-----------------
4138
Georg Brandl3e483f62008-07-16 22:57:41 +00004139- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4140 its methods now allow for items objects that can be converted to
4141 an integer using operator.index().
4142
Mark Dickinson64b7e502008-07-16 09:40:03 +00004143- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4144 produced a ValueError instead of giving the correct float.
4145
Eric Smitha5fa5a22008-07-16 00:11:49 +00004146- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4147 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4148
Mark Dickinson7103aa42008-07-15 19:08:33 +00004149- Issue #3008: the float type has a new instance method 'float.hex'
4150 and a new class method 'float.fromhex' to convert floating-point
4151 numbers to and from hexadecimal strings, respectively.
4152
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004153- Issue #2235: __hash__ is once again inherited by default. To allow
4154 collections.Hashable to remain meaningful in the presence of the
4155 default hash implementation (object.__hash__), it is now possible
4156 to explicit block inheritance of hash by setting __hash__=None at
4157 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4158 level.
4159
Nick Coghlanb028f502008-07-13 14:52:36 +00004160- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4161 the parent module cannot be found while performing an absolute import.
4162 This means that an incorrectly defined __package__ attribute will
4163 now only prevent relative imports in that module rather than causing
4164 all imports from that module to fail.
4165
Nick Coghlan14ff9942008-07-08 14:21:42 +00004166- Issue #2517: Allow unicode messages in Exceptions again by correctly
4167 bypassing the instance dictionary when looking up __unicode__ on
4168 new-style classes.
4169
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004170- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4171 set to a custom object whose write() method happens to install
4172 another file in sys.stdout.
4173
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004174- Issue #3088: Corrected a race condition in classes derived from
4175 threading.local: the first member set by a thread could be saved in
4176 another thread's dictionary.
4177
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004178- Issue #3004: Minor change to slice.indices(): the start and stop
4179 arguments are now treated identically, making the behaviour easier
4180 to describe and understand. For example, slice(None, -10,
4181 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4182 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4183 10, -1).
4184
Georg Brandl278fc502008-07-19 12:46:12 +00004185- Issue #3219: Calling a function with repeated keyword arguments,
4186 f(a=2, a=23), would not cause a syntax error. This was a regression
4187 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004188
Georg Brandl278fc502008-07-19 12:46:12 +00004189- Issue #2862: Make int and float freelist management consistent with
4190 other freelists. Changes their CompactFreeList apis into
4191 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004192

Thomas Heller57adf222008-08-14 19:10:48 +00004196- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4197 api functions without holding the GIL, which could lead to a fatal
4198 error when they failed.
4199
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004200- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004208- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4209 ForkingPickler.register() to resolve conflict with ctypes.
4210
Vinay Sajip51e65192008-07-18 09:01:10 +00004211- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00004213- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4214 a valid dlerror() message.
4215
Thomas Heller2bad6572008-07-15 17:19:50 +00004216- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4217 incomplete structure was created.
4218

4222
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004223- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004224
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004225- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4226 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004227 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004228 content-length. The problem had been corrected in the 2.4 branch, but never
4229 merged into trunk.
4230
Georg Brandle78fbcc2008-07-05 10:13:36 +00004231- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004242 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004243
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004244- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4245 handling is now the same as that of other special attributes like __name__).
4246
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004247- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4248 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004637 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004638
4639 This is controlled by the configure argument ``--with-universal-archs``:
4640
4641 - ``--with-universal-archs=all``: install 4-way universal
4642
4643 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4644
4645 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4646
4647 This option should be used in combination with ``--enable-universalsdk=``.
4648
4649 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 +00004699- Issue #1631171: Re-implement the 'warnings' module in C (the
4700 original Python code has been kept as backup). This will allow for
4701 using the 'warning's machinery in such places as the parser where
4702 use of pure Python code is not possible. Both the ``showarning()``
4703 and ``formatwarning()`` gain an optional 'line' argument which is
4704 not called by default for backwards-compatibility reasons. Setting
4705 ``warnings.showwarning()`` to an implementation that lacks support
4706 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004769- Issue #2550: The approach used by client/server code for obtaining
4770 ports to listen on in network-oriented tests has been refined in an
4771 effort to facilitate running multiple instances of the entire
4772 regression test suite in parallel without issue.
4773 test_support.bind_port() has been fixed such that it will always
4774 return a unique port -- which wasn't always the case with the
4775 previous implementation, especially if socket options had been set
4776 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4777 new implementation of bind_port() will actually raise an exception
4778 if it is passed an AF_INET/SOCK_STREAM socket with either the
4779 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4780 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4781 the socket it's been passed. This currently only applies to
4782 Windows. This option prevents any other sockets from binding to the
4783 host/port we've bound to, thus removing the possibility of the
4784 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4785 when a second SOCK_STREAM socket binds and accepts to a host/port
4786 that's already been bound by another socket. The optional preferred
4787 port parameter to bind_port() has been removed. Under no
4788 circumstances should tests be hard coding ports!
4789
4790 test_support.find_unused_port() has also been introduced, which will
4791 pass a temporary socket object to bind_port() in order to obtain an
4792 unused port. The temporary socket object is then closed and
4793 deleted, and the port is returned. This method should only be used
4794 for obtaining an unused port in order to pass to an external program
4795 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4796 a parameter to a server-oriented class that doesn't give you direct
4797 access to the underlying socket used.
4798
4799 Finally, test_support.HOST has been introduced, which should be used
4800 for the host argument of any relevant socket calls (i.e. bind and
4801 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004802
4803 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004804 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004805 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4806 test_asynchat and test_socket_ssl.
4807
Georg Brandl3ee81df2008-05-17 18:14:43 +00004808 It is now possible for multiple instances of the regression test

Fred Drakea8ee94b2008-03-01 02:45:07 +00005078- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005079 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005080
Georg Brandlad61bc82008-02-23 15:11:18 +00005081- Issue #2067: file.__exit__() now calls subclasses' close() method.
5082
5083- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005084
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005085- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005086 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005087
Eric Smitha73fbe72008-02-23 03:09:44 +00005088- Added the future_builtins module, which contains hex() and oct().
5089 These are the PEP 3127 version of these functions, designed to be
5090 compatible with the hex() and oct() builtins from Python 3.0. They
5091 differ slightly in their output formats from the existing, unchanged
5092 Python 2.6 builtins. The expected usage of the future_builtins
5093 module is:
5094 from future_builtins import hex, oct
5095
Eric Smith7ef40bf2008-02-20 23:34:22 +00005096- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5097 exponents for exponents with absolute value < 100. Follows C99
5098 standard. This is a change on Windows, which would use 3 digits.
5099 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5100 so that any alterations it does to the resulting string will be
5101 available in stringlib/formatter.h (for float.__format__).
5102
Eric Smith5a3c1352008-02-19 13:21:56 +00005103- Implemented PEP 3101, Advanced String Formatting. This adds a new
5104 builtin format(); a format() method for str and unicode; a
5105 __format__() method to object, str, unicode, int, long, float, and
5106 datetime; the class string.Formatter; and the C API
5107 PyObject_Format().
5108
Georg Brandl3ee81df2008-05-17 18:14:43 +00005109- Fixed several potential crashes, all caused by specially crafted
5110 __del__ methods exploiting objects in temporarily inconsistent
5111 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005112
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005113- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005114 prevent a possible crash: an Abstract Base Class would try to access
5115 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005116
Georg Brandl3ee81df2008-05-17 18:14:43 +00005117- Fixed repr() and str() of complex numbers with infinity or nan as
5118 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005119
Georg Brandl3ee81df2008-05-17 18:14:43 +00005120- Clear all free lists during a gc.collect() of the highest generation
5121 in order to allow pymalloc to free more arenas. Python may give back
5122 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Issue #2045: Fix an infinite recursion triggered when printing a
5125 subclass of collections.defaultdict, if its default_factory is set
5126 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005127
Christian Heimesf75dbef2008-02-08 00:11:31 +00005128- Fixed a minor memory leak in dictobject.c. The content of the free
5129 list was not freed on interpreter shutdown.
5130
Georg Brandl21e99f42010-03-07 15:23:59 +00005131- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005132 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5135 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005136 to compact the internal free lists of pre-allocted ints and floats.
5137
Georg Brandl3ee81df2008-05-17 18:14:43 +00005138- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5139 calls. Python expected the return type int but the fork familie
5140 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005141
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5143 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5146 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5149 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005150
Georg Brandl3ee81df2008-05-17 18:14:43 +00005151- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5152 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005153
Georg Brandl3ee81df2008-05-17 18:14:43 +00005154- Patch #1473257: generator objects gain a gi_code attribute. This is
5155 the same object as the func_code attribute of the function that
5156 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005157
Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Issue #1920: "while 0" statements were completely removed by the
5159 compiler, even in the presence of an "else" clause, which is
5160 supposed to be run when the condition is false. Now the compiler
5161 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005162
Guido van Rossumeead05f2008-01-24 18:21:02 +00005163- A few crashers fixed: weakref_in_del.py (issue #1377858);
5164 loosing_dict_ref.py (issue #1303614, test67.py);
5165 borrowed_ref_[34].py (not in tracker).
5166
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005167- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005168 suppressed while an extension is loaded by calling SetErrorMode in
5169 dynload_win.c. The error is still reported properly.
5170
Georg Brandl3ee81df2008-05-17 18:14:43 +00005171- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005172 several extension methods and modules do not work without unicode
5173 support.
5174
Georg Brandl26543b12008-01-21 18:36:51 +00005175- Issue #1882: when compiling code from a string, encoding cookies in the
5176 second line of code were not always recognized correctly.
5177
Georg Brandl14404b62008-01-19 19:27:05 +00005178- Issue #1679: "0x" was taken as a valid integer literal.
5179
Georg Brandl6caad7d2008-01-26 14:19:22 +00005180- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005181 added.
5182
Christian Heimesc94e2b52008-01-14 04:13:37 +00005183- sys.float_info / PyFloat_GetInfo: The floating point information
5184 object was converted from a dict to a specialized structseq object.
5185
Georg Brandl3ee81df2008-05-17 18:14:43 +00005186- Patch #1816: Added sys.flags structseq. It exposes the status of
5187 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005188
Georg Brandl3ee81df2008-05-17 18:14:43 +00005189- Objects/structseq.c: Implemented new structseq representation. The
5190 patch makes structseqs (e.g. the return value of os.stat) more
5191 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005192
Georg Brandl3ee81df2008-05-17 18:14:43 +00005193- Patch #1700288: added a type attribute cache that caches method
5194 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005195
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005196- Bug #1776: __import__() no longer accepts filenames on any platform.
5197 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005198
Georg Brandlaed6c662008-01-07 17:25:53 +00005199- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5200
Georg Brandl3ee81df2008-05-17 18:14:43 +00005201- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5202 envvar and sys.dont_write_bytecode attribute. All these can be set
5203 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005204
Georg Brandl3ee81df2008-05-17 18:14:43 +00005205- Improve some exception messages when Windows fails to load an
5206 extension module. Now we get for example '%1 is not a valid Win32
5207 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005208
Georg Brandl3ee81df2008-05-17 18:14:43 +00005209- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005211- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5212 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005213
Christian Heimes0a8143f2007-12-18 23:22:54 +00005214- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005215 and INF. float("nan"), float("inf") and float("-inf") now work on
5216 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005217
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218- Compiler now generates simpler and faster code for dictionary
5219 literals. The oparg for BUILD_MAP now indicates an estimated
5220 dictionary size. There is a new opcode, STORE_MAP, for adding
5221 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005222
Georg Brandl3ee81df2008-05-17 18:14:43 +00005223- Issue #1638: %zd configure test fails on Linux.

5251 file can now be directly executed by passing their name to the
5252 interpreter. The directory/zipfile is automatically inserted as the
5253 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005254
Georg Brandl3ee81df2008-05-17 18:14:43 +00005255- Issue #1265: Fix a problem with sys.settrace, if the tracing
5256 function uses a generator expression when at the same time the
5257 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005258
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005259- sets and frozensets now have an isdisjoint() method.
5260
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005261- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00005263- Fix warnings found by the new version of the Coverity checker.
5264
Georg Brandl21e99f42010-03-07 15:23:59 +00005265- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005266 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5267 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269- Issue #1686386: Tuple's tp_repr did not take into account the
5270 possibility of having a self-referential tuple, which is possible
5271 from C code. Nor did object's tp_str consider that a type's tp_str
5272 could do something that could lead to an inifinite recursion.
5273 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5274 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005275
Georg Brandl3ee81df2008-05-17 18:14:43 +00005276- Issue #1164: It was possible to trigger deadlock when using the
5277 'print' statement to write to a file since the GIL was not released
5278 as needed. Now PyObject_Print() does the right thing along with
5279 various tp_print implementations of the built-in types and those in
5280 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005281
Georg Brandl3ee81df2008-05-17 18:14:43 +00005282- Issue #1147: Exceptions were directly allowing string exceptions in
5283 their throw() method even though string exceptions no longer
5284 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005285

Brett Cannon1e534b52007-09-07 04:18:30 +00005289- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005290 PyObject_Call() never calling back out to Python code to trigger
5291 recursion depth updates/checks. Required the creation of a static
5292 RuntimeError instance in case normalizing an exception put the
5293 recursion check value past its limit. Fixes crashers
5294 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005295

Neal Norwitz0ac60192007-05-27 04:08:54 +00005309- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005310 __*__ attributes. (Some already existed, e.g., __doc__ and
5311 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005312
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005313- Add -3 option to the interpreter to warn about features that are
5314 deprecated and will be changed/removed in Python 3.0.
5315
Georg Brandl2134e752007-05-21 20:34:16 +00005316- Patch #1686487: you can now pass any mapping after '**' in function
5317 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005320 "except E as target:". This is to provide forwards compatibility
5321 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00005342- Bug #1683368: The object.__init__() and object.__new__() methods are
5343 now stricter in rejecting excess arguments. The only time when
5344 either allows excess arguments is when it is not overridden and the
5345 other one is. For backwards compatibility, when both are
5346 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005347 warning later). Also, type.__init__() insists on the same signature
5348 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005350- Patch #1675423: PyComplex_AsCComplex() now tries to convert an

5352 to the __float__() method. Therefore, the functions in the cmath
5353 module now can operate on objects that define a __complex__()
5354 method.

5374
Georg Brandl871f1bc2007-03-12 13:17:36 +00005375- The dir() function has been extended to call the __dir__() method on

5377 allows customizing the output of dir() in the presence of a

5388 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005390- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005391 makes the filenames the warning module prints much more sensible
5392 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006320- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6321 with RFC 3207 and forgets any knowledge obtained from the server not
6322 obtained from the TLS negotiation itself. Patch contributed by Bill
6323 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006324
Georg Brandl3ee81df2008-05-17 18:14:43 +00006325- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006326 that the SMTP.starttls() caller no longer needs to call ehlo()
6327 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006328 does not claim to support starttls. Adds the
6329 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6410 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6411 silently miscode subclasses of those types. Now, it raises a
6412 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006413

Georg Brandl3ee81df2008-05-17 18:14:43 +00006428 time so that opening a database previously created with the DB_DUP
6429 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6430 opens. Specifically: dictionary assignment to a DB object will
6431 replace all values for a given key when the database allows
6432 duplicate values. DB users should use DB.put(k, v) when they want
6433 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006434

6440 characters with ASCII value less than 32. Also, it correctly quotes
6441 dots only if they occur on a single line, as opposed to the previous
6442 behavior of quoting dots if they are the second character of any
6443 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006444

6786 ``PyFloat_GetInfo()`` to the float API.
6787
Georg Brandl3ee81df2008-05-17 18:14:43 +00006788- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6789 of w# format code incorrectly truncated the length to an int, even
6790 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6791 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006792
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6794 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006796- PEP 3123: Provide forward compatibility with Python 3.0, while
6797 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
6798 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006800- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
6801 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006802
6803- Patch #1733960: Allow T_LONGLONG to accept ints.
6804
6805- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

6810
6811- Fix some leftovers from the conversion from int to Py_ssize_t
6812 (relevant to strings and sequences of more than 2**31 items).
6813
6814- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6815 outside of pystate.c and should not be necessary.
6816
Georg Brandl3ee81df2008-05-17 18:14:43 +00006817- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00006821- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6822 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006823
Georg Brandl3ee81df2008-05-17 18:14:43 +00006824- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006831- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6832 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6833 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6834 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- Removed the macfs module. It had been deprecated since Python 2.5.
6850 This lead to the deprecation of macostools.touched() as it relied
6851 solely on macfs and was a no-op under OS X.
