1216
1217- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1218 and later systems as is currently done for Python 3.x installers.
1219 For 2.7.7 only, we will provide three installers:
1220 the legacy deprecated 10.3+ 32-bit-only format;
1221 the newer 10.5+ 32-bit-only format;
1222 and the unchanged 10.6+ 64-/32-bit format.
1223 Although binary installers will no longer be available from
1224 python.org as of 2.7.8, it will still be possible to build from
1225 source on 10.3.9 and 10.4 systems if necessary.
1226 See Mac/BuildScript/README.txt for more information.

Ned Deilyf84b5312013-10-25 00:44:46 -07001554- Issue #19019: Change the OS X installer build script to use CFLAGS instead
1555 of OPT for special build options. By setting OPT, some compiler-specific
1556 options like -fwrapv were overridden and thus not used, which could result

2608 32-bit-only installer Pythons on systems with Xcode 4 (currently
2609 OS X 10.8, 10.7, and optionally 10.6).
2610 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2611 * Since Xcode 4 removes ppc support, extension module builds now
2612 check for ppc compiler support and by default remove ppc and
2613 ppc64 archs when they are not available.
2614 * Extension module builds now revert to using system installed
2615 headers and libs (/usr and /System/Library) if the SDK used
2616 to build the interpreter is not installed or has moved.
2617 * Try to avoid building extension modules with deprecated
2618 and problematic Apple llvm-gcc compiler. If original compiler
2619 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003056- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003057 has left two versions of customize_compiler, the original in
3058 distutils.sysconfig and another copy in distutils.ccompiler, with some

3061 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01003063- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3064 Distutils-based packages with C extension modules may fail because
3065 Apple has removed gcc-4.2, the version used to build python.org
3066 64-bit/32-bit Pythons. If the user does not explicitly override
3067 the default C compiler by setting the CC environment variable,
3068 Distutils will now attempt to compile extension modules with clang
3069 if gcc-4.2 is required but not found. Also as a convenience, if
3070 the user does explicitly set CC, substitute its value as the default
3071 compiler in the Distutils LDSHARED configuration variable for OS X.
3072 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3073 SDK, neither of which are available in Xcode 4. This change does not
3074 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003324- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3325 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3326 interpreter process. This could cause failures in non-Distutils subprocesses
3327 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003328 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003329 deployment target only in the environment of each build subprocess. It is
3330 still possible to globally override the default by setting
3331 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3332 greater or equal to the default value, the value with which the interpreter
3333 was built.

3362 updating the check interval, so if the user decreases the check interval,
3363 the ticker doesn't have to wind down to zero from the old starting point
3364 before the new interval takes effect. And if the user increases the
3365 interval, it makes sure the new limit takes effect right away rather have an
3366 early task switch before recognizing the new interval.

4362
Raymond Hettinger20397532010-09-12 02:11:45 +00004363- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4364 This prevents user-created self-referencing ordered dictionaries from
4365 becoming permanently uncollectable GC garbage. The downside is that
4366 removing __del__ means that the internal doubly-linked list has to wait for
4367 GC collection rather than freeing memory immediately when the refcnt drops
4368 to zero.

4373
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004374- Issue #9792: In case of connection failure, socket.create_connection()
4375 would swallow the exception and raise a new one, making it impossible
4376 to fetch the original errno, or to filter timeout errors. Now the
4377 original error is re-raised.

4825
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004826- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4827 start byte and the continuation byte(s) are now considered invalid, instead
4828 of the number of bytes specified by the start byte.
4829 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4830 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4831 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4832 Previous versions returned a single u'\ufffd'.

4836 arises from the "Overriding __eq__ blocks inheritance ..." warning
4837 when turned into an exception: in this case the exception simply
4838 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004840- Issue #8748: Fix two issues with comparisons between complex and integer
4841 objects. (1) The comparison could incorrectly return True in some cases
4842 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4843 (2) The comparison raised an OverflowError for large integers, leading
4844 to unpredictable exceptions when combining integers and complex objects
4845 in sets or dicts.
4846
Mark Dickinson81336372010-05-30 12:12:25 +00004847- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00005725 file position when calling `truncate()`. It would previously change the file
5726 position to the given argument, which goes against the tradition of

5730 class used to represent files stored inside an archive. The new
5731 implementation is significantly faster and can be wrapped in a
5732 ``io.BufferedReader`` object for more speedups. It also solves an issue
5733 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5822-----------------
5823
Georg Brandlba83f822010-03-14 09:50:54 +00005824- The ``__complex__()`` method is now looked up on the class of instances to
5825 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005827- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

5829
Mark Dickinson1b34d252010-01-01 17:27:30 +00005830- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005831 DeprecationWarning when passed a float argument where an integer was expected.
5832 These functions and methods now raise TypeError instead. The majority of the
5833 effects of this change are in the extension modules, but some core functions
5834 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5835 and many unicode/str methods.

5849 of integers: the result of a/b is now correctly rounded for ints a and b (at
5850 least on IEEE 754 platforms), and in particular does not depend on the
5851 internal representation of a long.

5859
Georg Brandlba83f822010-03-14 09:50:54 +00005860 These executables now work properly with the arch(1) command: ``arch -ppc
5861 python`` will start a universal binary version of python in PPC mode (unlike

5947 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5948 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5949 float arguments for integer format codes (other than 'L'): previously an
5950 attempt to pass a float resulted in a DeprecationWarning; now it gives a
5951 TypeError. For the 'L' format code (which previously had no warning) there is
5952 now a DeprecationWarning.

6001 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00006002

6004 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00006016
Georg Brandlba83f822010-03-14 09:50:54 +00006017- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6018 decimal string that's guaranteed to round back to x under correct rounding
6019 (with round-half-to-even rounding mode). Previously it gave a string based on
6020 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6021 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6022 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006023
Georg Brandlba83f822010-03-14 09:50:54 +00006024- Issue #7117: On almost all platforms: float-to-string and string-to-float
6025 conversions within Python are now correctly rounded. Places these conversions
6026 occur include: str for floats and complex numbers; the float and complex
6027 constructors; old-style and new-style numeric formatting; serialization and
6028 deserialization of floats and complex numbers using marshal, pickle and json;
6029 parsing of float and imaginary literals in Python code; Decimal-to-float
6030 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006031
Georg Brandlba83f822010-03-14 09:50:54 +00006032 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6033 providing correctly-rounded strtod and dtoa C functions. This code is
6034 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6035 the C compiler. There may be a small number of platforms on which correct
6036 operation of this code cannot be guaranteed, so the code is not used: notably,
6037 this applies to platforms where the C double format is not IEEE 754 binary64,
6038 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6039 and Python's configure script is unable to determine how to change the FPU
6040 precision. On these platforms conversions use the platform strtod and dtoa,
6041 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006042
Georg Brandlba83f822010-03-14 09:50:54 +00006043- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6044 uses the correctly-rounded string <-> float conversions described above (when
6045 available), and so produces correctly rounded results that will display nicely
6046 under the float repr. There are two related small changes: (1) round now
6047 accepts any class with an ``__index__()`` method for its second argument (but
6048 no longer accepts floats for the second argument), and (2) an excessively
6049 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6050 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006180- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
6181 consistent with float("1e500") and interpretation of real and imaginary
6182 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00006191- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00006192
Georg Brandlba83f822010-03-14 09:50:54 +00006193 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
6194 (2) parsing of strings representing infinities and nans was locale aware; and
6195 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00006197- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6198 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6199 but with at least one decimal point and with a default precision
6200 of 12. Previously, the behavior the same but with a default precision of 6.
6201 This more closely matches ``str()``, and reduces surprises when adding
6202 alignment flags to the empty presentation type. This also affects the new
6203 complex.__format__ in the same way.
6204
6205- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
6206 classtype's, even if it was None. property now inserts the __doc__ into the
6207 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00006267- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00006268 untrackable objects are not tracked by the garbage collector. This can reduce
6269 the size of collections and therefore the garbage collection overhead on

6277 internal representation of integers, for performance reasons. Base 2**30 is
6278 enabled by default on 64-bit machines. Add --enable-big-digits option to
6279 configure, which overrides the default. Add sys.long_info structseq to
6280 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00006427- On windows, ``os.chdir()`` given unicode was not working if

6429 this code path is really executed because I cannot move to such directory on
6430 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006432- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6433 element is temporarily replaced with an equivalent frozenset. But the
6434 eventual KeyError would always report the empty ``frozenset()`` as the missing
6435 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006455- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6456 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6457 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6458 of using the replace error handler in PyUnicode_DecodeUTF8().
6459
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006460- Issue #3739: The unicode-internal encoder now reports the number of characters

6462
Georg Brandlba83f822010-03-14 09:50:54 +00006463- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6464 allocator will be automatically disabled when running under Valgrind. This
6465 gives improved memory leak detection when running under Valgrind, while taking
6466 advantage of pymalloc at other times.

7657 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7658 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00007713 leak-chasing test runs give sensible results. The previous method of reaping
7714 threads could return successfully while some Thread objects were still

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007855- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7856
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007857- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7858 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7859 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7860 ``printf`` function, whereas PyString_FromFormat has an independent
7861 implementation and uses "%zd" on all platforms for size_t values.
7862 This makes a difference on win64, where ``printf`` needs "%Id" to display
7863 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007865- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7869 object; previously an int would be returned for small values. the __long__
7870 method is allowed to return either an int or a long, but the behaviour of
7871 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007880 was correctly parsed but parsing of subsequent arguments failed.
7881
Vinay Sajip35e3b032008-09-01 14:33:59 +00007882- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007883 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7884 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7885 when given a tuple of classes as second argument, were looking up
7886 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7887 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007958 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7959 for catch_warnings() also led to an improvement in the raising of a

8032-----------------
8033
Guido van Rossumf8402962008-08-20 15:01:50 +00008034- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8035 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8036 extensions do not automatically benefit from the class attribute
8037 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8038 to their tp_flags field if they care. This is a backwards
8039 compatibility feature; in 3.0, all types will use the cache by
8040 default.
8041
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008042- Keyword arguments can now follow starred arguments. (``f(a, *args,
8043 keyword=23)`` is now valid syntax.)
8044
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008045- ctypes function pointers that are COM methods have a boolean True
8046 value again.

8057
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008058- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8059 (64bit Unix, for example), unichr() would truncate its argument and return
8060 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

8069
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008070- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8071 the python debugger steps into a class statement: the free variables (local
8072 variables defined in an outer scope) would be deleted from the outer scope.
8073
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008074- Issue #2620: Overflow checking when allocating or reallocating memory
8075 was not always being done properly in some python types and extension
8076 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8077 all been updated to perform better checks and places in the code that
8078 would previously leak memory on the error path when such an allocation
8079 failed have been fixed.

8085
Benjamin Petersone977ad42008-08-20 01:42:01 +00008086- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8087 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8088
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008089- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8090 version reported by these tools does not necessarily follow the python
8091 version numbering scheme, so the module is less strict when parsing it.
8092
Nick Coghlanf70385a2008-08-18 12:42:46 +00008093- Issue #2235: Added Py3k warnings for types which will become unhashable
8094 under the stricter __hash__ inheritance rules in 3.0. Several types
8095 which did not meet the rules for hash invariants and were already
8096 unhashable in 3.0 have now been explicitly flagged as unhashable in
8097 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8098 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8099
Brett Cannon88f801d2008-08-18 00:46:22 +00008100- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8101 imported into the module but exposed as part of the module's API.
8102

8126 regular expression.
8127
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008128- Issue #3476: binary buffered reading through the new "io" library is now
8129 thread-safe.

Brett Cannonbf3157b2008-08-14 05:00:03 +00008131- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8132 since mimetools itself is deprecated. Because modules are cached, all
8133 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8134
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008135- Issue #3134: shutil referenced undefined WindowsError symbol.

8144 a MemoryError rather than silently stop the iteration.
8145
Guido van Rossum59ce9012008-08-09 14:55:34 +00008146- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8147 to _sre.compile() will now be rejected. This should not affect anybody
8148 since the re.compile() function never generates invalid re-bytecode.
8149
Skip Montanaroa032bf42008-08-08 22:52:51 +00008150- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8151 upon first access it can be automatically initialized from the csv file if
8152 it wasn't initialized during instantiation.
8153
Brett Cannon3aa2a492008-08-06 22:28:09 +00008154- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8155 the reload() built-in has been removed.
8156
Brett Cannon7e30b672008-08-04 21:52:25 +00008157- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00008169 asking for a specific length. This problem only affected files opened
8170 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008195- Issue #3394: zipfile.writestr sets external attributes when passed a
8196 file name rather than a ZipInfo instance, so files are extracted with
8197 mode 0600 rather than 000 under Unix.
8198
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008199- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8200 argument in python 2.5, this broke code that subclassed Popen to include its

8212 interaction with the tp_hash slot (added in 2.6b2) are now documented
8213
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008214- Issue #643841: The language reference now provides more detailed
8215 coverage of the lookup process for special methods. The disclaimers
8216 regarding lack of coverage of new-style classes have also been
8217 removed, since the coverage is now fairly reasonable.

8221================================
8222
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008223*Release date: 17-Jul-2008*
8224
Raymond Hettingere3ae6552008-06-20 04:18:15 +00008225Core and Builtins
8226-----------------
8227
Georg Brandl3e483f62008-07-16 22:57:41 +00008228- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8229 its methods now allow for items objects that can be converted to
8230 an integer using operator.index().
8231
Mark Dickinson64b7e502008-07-16 09:40:03 +00008232- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8233 produced a ValueError instead of giving the correct float.
8234
Eric Smitha5fa5a22008-07-16 00:11:49 +00008235- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8236 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8237
Mark Dickinson7103aa42008-07-15 19:08:33 +00008238- Issue #3008: the float type has a new instance method 'float.hex'
8239 and a new class method 'float.fromhex' to convert floating-point
8240 numbers to and from hexadecimal strings, respectively.
8241
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008242- Issue #2235: __hash__ is once again inherited by default. To allow
8243 collections.Hashable to remain meaningful in the presence of the
8244 default hash implementation (object.__hash__), it is now possible
8245 to explicit block inheritance of hash by setting __hash__=None at
8246 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8247 level.
8248
Nick Coghlanb028f502008-07-13 14:52:36 +00008249- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8250 the parent module cannot be found while performing an absolute import.
8251 This means that an incorrectly defined __package__ attribute will
8252 now only prevent relative imports in that module rather than causing
8253 all imports from that module to fail.
8254
Nick Coghlan14ff9942008-07-08 14:21:42 +00008255- Issue #2517: Allow unicode messages in Exceptions again by correctly
8256 bypassing the instance dictionary when looking up __unicode__ on
8257 new-style classes.
8258
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008259- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8260 set to a custom object whose write() method happens to install
8261 another file in sys.stdout.
8262
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008263- Issue #3088: Corrected a race condition in classes derived from
8264 threading.local: the first member set by a thread could be saved in
8265 another thread's dictionary.
8266
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008267- Issue #3004: Minor change to slice.indices(): the start and stop
8268 arguments are now treated identically, making the behaviour easier
8269 to describe and understand. For example, slice(None, -10,
8270 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8271 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8272 10, -1).
8273
Georg Brandl278fc502008-07-19 12:46:12 +00008274- Issue #3219: Calling a function with repeated keyword arguments,
8275 f(a=2, a=23), would not cause a syntax error. This was a regression
8276 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008277
Georg Brandl278fc502008-07-19 12:46:12 +00008278- Issue #2862: Make int and float freelist management consistent with
8279 other freelists. Changes their CompactFreeList apis into
8280 ClearFreeList apis and calls them via gc.collect().

8286 api functions without holding the GIL, which could lead to a fatal
8287 error when they failed.
8288
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008289- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00008297- Issue #3125: Remove copy_reg in multiprocessing and replace it with
8298 ForkingPickler.register() to resolve conflict with ctypes.
8299
Vinay Sajip51e65192008-07-18 09:01:10 +00008300- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00008302- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8303 a valid dlerror() message.
8304
Thomas Heller2bad6572008-07-15 17:19:50 +00008305- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8306 incomplete structure was created.
8307

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008312- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008313
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008314- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8315 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008316 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008317 content-length. The problem had been corrected in the 2.4 branch, but never
8318 merged into trunk.
8319

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008333- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8334 handling is now the same as that of other special attributes like __name__).
8335
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008336- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00008724 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008725
8726 This is controlled by the configure argument ``--with-universal-archs``:
8727
8728 - ``--with-universal-archs=all``: install 4-way universal
8729
8730 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8731
8732 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8733
8734 This option should be used in combination with ``--enable-universalsdk=``.
8735
8736 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 +00008785- Issue #1631171: Re-implement the 'warnings' module in C (the
8786 original Python code has been kept as backup). This will allow for
8787 using the 'warning's machinery in such places as the parser where
8788 use of pure Python code is not possible. Both the ``showarning()``
8789 and ``formatwarning()`` gain an optional 'line' argument which is
8790 not called by default for backwards-compatibility reasons. Setting
8791 ``warnings.showwarning()`` to an implementation that lacks support
8792 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008855- Issue #2550: The approach used by client/server code for obtaining
8856 ports to listen on in network-oriented tests has been refined in an
8857 effort to facilitate running multiple instances of the entire
8858 regression test suite in parallel without issue.
8859 test_support.bind_port() has been fixed such that it will always
8860 return a unique port -- which wasn't always the case with the
8861 previous implementation, especially if socket options had been set
8862 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8863 new implementation of bind_port() will actually raise an exception
8864 if it is passed an AF_INET/SOCK_STREAM socket with either the
8865 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8866 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8867 the socket it's been passed. This currently only applies to
8868 Windows. This option prevents any other sockets from binding to the
8869 host/port we've bound to, thus removing the possibility of the
8870 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8871 when a second SOCK_STREAM socket binds and accepts to a host/port
8872 that's already been bound by another socket. The optional preferred
8873 port parameter to bind_port() has been removed. Under no
8874 circumstances should tests be hard coding ports!
8875
8876 test_support.find_unused_port() has also been introduced, which will
8877 pass a temporary socket object to bind_port() in order to obtain an
8878 unused port. The temporary socket object is then closed and
8879 deleted, and the port is returned. This method should only be used
8880 for obtaining an unused port in order to pass to an external program
8881 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8882 a parameter to a server-oriented class that doesn't give you direct
8883 access to the underlying socket used.
8884
8885 Finally, test_support.HOST has been introduced, which should be used
8886 for the host argument of any relevant socket calls (i.e. bind and
8887 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008888
8889 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008890 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008891 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8892 test_asynchat and test_socket_ssl.
8893
Georg Brandl3ee81df2008-05-17 18:14:43 +00008894 It is now possible for multiple instances of the regression test

Facundo Batistafc2d0102008-02-23 12:01:13 +00009173
Eric Smitha73fbe72008-02-23 03:09:44 +00009174- Added the future_builtins module, which contains hex() and oct().
9175 These are the PEP 3127 version of these functions, designed to be
9176 compatible with the hex() and oct() builtins from Python 3.0. They
9177 differ slightly in their output formats from the existing, unchanged
9178 Python 2.6 builtins. The expected usage of the future_builtins
9179 module is:
9180 from future_builtins import hex, oct
9181
Eric Smith7ef40bf2008-02-20 23:34:22 +00009182- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9183 exponents for exponents with absolute value < 100. Follows C99
9184 standard. This is a change on Windows, which would use 3 digits.
9185 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9186 so that any alterations it does to the resulting string will be
9187 available in stringlib/formatter.h (for float.__format__).
9188
Eric Smith5a3c1352008-02-19 13:21:56 +00009189- Implemented PEP 3101, Advanced String Formatting. This adds a new
9190 builtin format(); a format() method for str and unicode; a
9191 __format__() method to object, str, unicode, int, long, float, and
9192 datetime; the class string.Formatter; and the C API
9193 PyObject_Format().
9194
Georg Brandl3ee81df2008-05-17 18:14:43 +00009195- Fixed several potential crashes, all caused by specially crafted
9196 __del__ methods exploiting objects in temporarily inconsistent
9197 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009198
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009199- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009200 prevent a possible crash: an Abstract Base Class would try to access
9201 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009202

Georg Brandl3ee81df2008-05-17 18:14:43 +00009206- Clear all free lists during a gc.collect() of the highest generation
9207 in order to allow pymalloc to free more arenas. Python may give back
9208 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009209
Georg Brandl3ee81df2008-05-17 18:14:43 +00009210- Issue #2045: Fix an infinite recursion triggered when printing a
9211 subclass of collections.defaultdict, if its default_factory is set
9212 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009213
Christian Heimesf75dbef2008-02-08 00:11:31 +00009214- Fixed a minor memory leak in dictobject.c. The content of the free
9215 list was not freed on interpreter shutdown.
9216
Georg Brandl21e99f42010-03-07 15:23:59 +00009217- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009218 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009219
Georg Brandl3ee81df2008-05-17 18:14:43 +00009220- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9221 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009222 to compact the internal free lists of pre-allocted ints and floats.
9223
Georg Brandl3ee81df2008-05-17 18:14:43 +00009224- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9225 calls. Python expected the return type int but the fork familie
9226 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009240- Patch #1473257: generator objects gain a gi_code attribute. This is
9241 the same object as the func_code attribute of the function that
9242 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009243
Georg Brandl3ee81df2008-05-17 18:14:43 +00009244- Issue #1920: "while 0" statements were completely removed by the
9245 compiler, even in the presence of an "else" clause, which is
9246 supposed to be run when the condition is false. Now the compiler
9247 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009248
Guido van Rossumeead05f2008-01-24 18:21:02 +00009249- A few crashers fixed: weakref_in_del.py (issue #1377858);
9250 loosing_dict_ref.py (issue #1303614, test67.py);
9251 borrowed_ref_[34].py (not in tracker).
9252
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009253- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009254 suppressed while an extension is loaded by calling SetErrorMode in
9255 dynload_win.c. The error is still reported properly.
9256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009257- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009258 several extension methods and modules do not work without unicode
9259 support.
9260
Georg Brandl26543b12008-01-21 18:36:51 +00009261- Issue #1882: when compiling code from a string, encoding cookies in the

9265
Georg Brandl6caad7d2008-01-26 14:19:22 +00009266- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009267 added.
9268
Christian Heimesc94e2b52008-01-14 04:13:37 +00009269- sys.float_info / PyFloat_GetInfo: The floating point information
9270 object was converted from a dict to a specialized structseq object.
9271
Georg Brandl3ee81df2008-05-17 18:14:43 +00009272- Patch #1816: Added sys.flags structseq. It exposes the status of
9273 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009274
Georg Brandl3ee81df2008-05-17 18:14:43 +00009275- Objects/structseq.c: Implemented new structseq representation. The
9276 patch makes structseqs (e.g. the return value of os.stat) more
9277 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009278
Georg Brandl3ee81df2008-05-17 18:14:43 +00009279- Patch #1700288: added a type attribute cache that caches method
9280 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009281
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009282- Bug #1776: __import__() no longer accepts filenames on any platform.

9288 envvar and sys.dont_write_bytecode attribute. All these can be set
9289 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009290
Georg Brandl3ee81df2008-05-17 18:14:43 +00009291- Improve some exception messages when Windows fails to load an
9292 extension module. Now we get for example '%1 is not a valid Win32
9293 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009300- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009301 and INF. float("nan"), float("inf") and float("-inf") now work on
9302 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009303
Georg Brandl3ee81df2008-05-17 18:14:43 +00009304- Compiler now generates simpler and faster code for dictionary
9305 literals. The oparg for BUILD_MAP now indicates an estimated
9306 dictionary size. There is a new opcode, STORE_MAP, for adding
9307 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009341- Issue #1265: Fix a problem with sys.settrace, if the tracing
9342 function uses a generator expression when at the same time the
9343 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009344
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009345- sets and frozensets now have an isdisjoint() method.

9350
Georg Brandl21e99f42010-03-07 15:23:59 +00009351- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009352 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9353 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009354
Georg Brandl3ee81df2008-05-17 18:14:43 +00009355- Issue #1686386: Tuple's tp_repr did not take into account the
9356 possibility of having a self-referential tuple, which is possible
9357 from C code. Nor did object's tp_str consider that a type's tp_str
9358 could do something that could lead to an inifinite recursion.
9359 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9360 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009361
Georg Brandl3ee81df2008-05-17 18:14:43 +00009362- Issue #1164: It was possible to trigger deadlock when using the
9363 'print' statement to write to a file since the GIL was not released
9364 as needed. Now PyObject_Print() does the right thing along with
9365 various tp_print implementations of the built-in types and those in
9366 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009367
Georg Brandl3ee81df2008-05-17 18:14:43 +00009368- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00009375- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009376 PyObject_Call() never calling back out to Python code to trigger
9377 recursion depth updates/checks. Required the creation of a static
9378 RuntimeError instance in case normalizing an exception put the
9379 recursion check value past its limit. Fixes crashers
9380 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009406 "except E as target:". This is to provide forwards compatibility
9407 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009411- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00009414- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009415 setting a plain string, ie don't expand to single letter identifiers.
9416
Raymond Hettinger13936692007-04-11 18:40:58 +00009417- Request #1191699: Slices can now be pickled.

9427
Guido van Rossum143b5642007-03-23 04:58:42 +00009428- Bug #1683368: The object.__init__() and object.__new__() methods are
9429 now stricter in rejecting excess arguments. The only time when
9430 either allows excess arguments is when it is not overridden and the
9431 other one is. For backwards compatibility, when both are
9432 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009433 warning later). Also, type.__init__() insists on the same signature
9434 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009436- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9437 object to complex using its __complex__() method before falling back
9438 to the __float__() method. Therefore, the functions in the cmath
9439 module now can operate on objects that define a __complex__()
9440 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009458- Bug #1678647: write a newline after printing an exception in any
9459 case, even when converting the value to a string failed.
9460
Georg Brandl871f1bc2007-03-12 13:17:36 +00009461- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009462 its argument, if it exists. If not, it will work like before. This
9463 allows customizing the output of dir() in the presence of a
9464 __getattr__().

9474 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009475
Georg Brandlaa2321b2007-03-07 00:40:28 +00009476- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009477 makes the filenames the warning module prints much more sensible
9478 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009479

9492 sq_ass_slice instead of the sq_slice slot.
9493
Georg Brandl3ee81df2008-05-17 18:14:43 +00009494- When printing an unraisable error, don't print exceptions. before

10107 returned string up to the first NUL character.

10120 TestCase and TestSuite subclasses (not instances) are no longer
10121 accepted in TestSuite.addTest(). This should cause no

10123 -- the failure just occurred later, with a more cumbersome

10392 the first chunk fed to the decoder started with a BOM, but was
10393 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010394
Georg Brandl3ee81df2008-05-17 18:14:43 +000010395- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010404- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010405 that the SMTP.starttls() caller no longer needs to call ehlo()
10406 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010407 does not claim to support starttls. Adds the
10408 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010451- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010452 works as expected. ``mmap.find`` also takes an optional ``end``

10489 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10490 silently miscode subclasses of those types. Now, it raises a
10491 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010492

Georg Brandl3ee81df2008-05-17 18:14:43 +000010507 time so that opening a database previously created with the DB_DUP
10508 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10509 opens. Specifically: dictionary assignment to a DB object will
10510 replace all values for a given key when the database allows
10511 duplicate values. DB users should use DB.put(k, v) when they want
10512 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010513

10519 characters with ASCII value less than 32. Also, it correctly quotes
10520 dots only if they occur on a single line, as opposed to the previous
10521 behavior of quoting dots if they are the second character of any
10522 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010523

10851
Georg Brandl3ee81df2008-05-17 18:14:43 +000010852- Unified naming convention for free lists and their limits. All free
10853 lists in Object/ are named ``free_list``, the counter ``numfree``
10854 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10855 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010856
Georg Brandl3ee81df2008-05-17 18:14:43 +000010857- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10858 to ``PyTuple_SetItem``, it can be used to populate a brand new
10859 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010860
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010861- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010862
Georg Brandl3ee81df2008-05-17 18:14:43 +000010863- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10864 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10865 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010866
10867- Patch #1720595: add T_BOOL to the range of structmember types.
10868
10869- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10870 ``PyFloat_GetInfo()`` to the float API.
10871
Georg Brandl3ee81df2008-05-17 18:14:43 +000010872- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10873 of w# format code incorrectly truncated the length to an int, even
10874 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10875 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010876
Georg Brandl3ee81df2008-05-17 18:14:43 +000010877- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10878 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010879
Georg Brandl3ee81df2008-05-17 18:14:43 +000010880- PEP 3123: Provide forward compatibility with Python 3.0, while
10881 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10882 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010883
Georg Brandl3ee81df2008-05-17 18:14:43 +000010884- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10885 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010886
10887- Patch #1733960: Allow T_LONGLONG to accept ints.
10888
10889- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10890
Christian Heimes000a0742008-01-03 22:16:32 +000010891- Added a new API function ``PyImport_ImportModuleNoBlock``.
10892
Georg Brandl6caad7d2008-01-26 14:19:22 +000010893- Bug #1637022: Prefix AST symbols with _Py_.
10894
10895- Fix some leftovers from the conversion from int to Py_ssize_t
10896 (relevant to strings and sequences of more than 2**31 items).
10897
10898- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10899 outside of pystate.c and should not be necessary.
10900
Georg Brandl3ee81df2008-05-17 18:14:43 +000010901- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10902 absolute imports. In earlier versions they might have used relative
10903 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010904
Georg Brandl3ee81df2008-05-17 18:14:43 +000010905- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10906 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010907
Georg Brandl3ee81df2008-05-17 18:14:43 +000010908- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10909 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010914- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10915 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10916 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10917 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010918
Georg Brandl3ee81df2008-05-17 18:14:43 +000010919- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10920 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +000010929- buildtools now raises a DeprecationWarning.
10930
Georg Brandl3ee81df2008-05-17 18:14:43 +000010931- Removed the macfs module. It had been deprecated since Python 2.5.
10932 This lead to the deprecation of macostools.touched() as it relied
10933 solely on macfs and was a no-op under OS X.
