1065
1066- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1067 and later systems as is currently done for Python 3.x installers.
1068 For 2.7.7 only, we will provide three installers:
1069 the legacy deprecated 10.3+ 32-bit-only format;
1070 the newer 10.5+ 32-bit-only format;
1071 and the unchanged 10.6+ 64-/32-bit format.
1072 Although binary installers will no longer be available from
1073 python.org as of 2.7.8, it will still be possible to build from
1074 source on 10.3.9 and 10.4 systems if necessary.
1075 See Mac/BuildScript/README.txt for more information.

2457 32-bit-only installer Pythons on systems with Xcode 4 (currently
2458 OS X 10.8, 10.7, and optionally 10.6).
2459 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2460 * Since Xcode 4 removes ppc support, extension module builds now
2461 check for ppc compiler support and by default remove ppc and
2462 ppc64 archs when they are not available.
2463 * Extension module builds now revert to using system installed
2464 headers and libs (/usr and /System/Library) if the SDK used
2465 to build the interpreter is not installed or has moved.
2466 * Try to avoid building extension modules with deprecated
2467 and problematic Apple llvm-gcc compiler. If original compiler
2468 is not available, use clang instead by default.

2833 int.__pow__. These overflow checks were causing int.__pow__ to produce
2834 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002835 compiler optimizing the check away. Also fix similar overflow checks
2836 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

2849 cleared by the garbage collector. This fixes a segfault when an instance
2850 and its type get caught in a reference cycle, and the instance's
2851 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +01002905- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002906 has left two versions of customize_compiler, the original in
2907 distutils.sysconfig and another copy in distutils.ccompiler, with some

2910 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002912- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2913 Distutils-based packages with C extension modules may fail because
2914 Apple has removed gcc-4.2, the version used to build python.org
2915 64-bit/32-bit Pythons. If the user does not explicitly override
2916 the default C compiler by setting the CC environment variable,
2917 Distutils will now attempt to compile extension modules with clang
2918 if gcc-4.2 is required but not found. Also as a convenience, if
2919 the user does explicitly set CC, substitute its value as the default
2920 compiler in the Distutils LDSHARED configuration variable for OS X.
2921 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2922 SDK, neither of which are available in Xcode 4. This change does not
2923 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003173- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3174 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3175 interpreter process. This could cause failures in non-Distutils subprocesses
3176 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003177 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003178 deployment target only in the environment of each build subprocess. It is
3179 still possible to globally override the default by setting
3180 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3181 greater or equal to the default value, the value with which the interpreter
3182 was built.

3191 times without error, and _ProxyFile now closes the wrapped file.
3192
Victor Stinnerc74a6ba2011-06-17 14:06:27 +02003193- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
3194 connection if its getresponse() method fails with a socket error. Patch
3195 written by Ezio Melotti.
3196
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -05003197- Issue #9284: Allow inspect.findsource() to find the source of doctest

3209
Barry Warsawc5643282011-07-19 17:06:30 -04003210- sys.setcheckinterval() now updates the current ticker count as well as
3211 updating the check interval, so if the user decreases the check interval,
3212 the ticker doesn't have to wind down to zero from the old starting point
3213 before the new interval takes effect. And if the user increases the
3214 interval, it makes sure the new limit takes effect right away rather have an
3215 early task switch before recognizing the new interval.

4213 This prevents user-created self-referencing ordered dictionaries from
4214 becoming permanently uncollectable GC garbage. The downside is that
4215 removing __del__ means that the internal doubly-linked list has to wait for
4216 GC collection rather than freeing memory immediately when the refcnt drops
4217 to zero.

R. David Murray7c4bf552010-08-25 01:45:57 +00004248- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4249 character years even if the message contains RFC822 two character years.

4285 when the underlying raw IO channel was e.g. a socket. Report and original
4286 patch by Jason V. Miller.

4678 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4679 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

4691 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00005036 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
5037 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
5038 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

5059-----------------
5060
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005061- Issue #7301: Add environment variable $PYTHONWARNINGS.
5062
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005063- Issue #8329: Don't return the same lists from select.select when no fds are
5064 changed.
5065
Georg Brandlfee0f442010-05-22 21:26:21 +00005066- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005067 on 64-bit machines. The shift count for either left or right shift is
5068 permitted to be up to sys.maxsize.
5069
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00005070- Ensure that tokenization of identifiers is not affected by locale.
5071
Georg Brandlfee0f442010-05-22 21:26:21 +00005072- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00005073
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00005074- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
5075
Georg Brandlfee0f442010-05-22 21:26:21 +00005076- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5077 with a non-empty format string. This is an effort to future-proof user
5078 code. If a derived class does not currently implement __format__ but later
5079 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005080 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005081 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005082
Antoine Pitroua57df2c2010-03-31 21:32:15 +00005083- Issue #8268: Old-style classes (not just instances) now support weak

5095
Victor Stinner66644262010-03-10 22:30:19 +00005096- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005097 (SIGINT). If an error occurs while importing the site module, the error is
5098 printed and Python exits. Initialize the GIL before importing the site

5113
Georg Brandlfee0f442010-05-22 21:26:21 +00005114- Issue #8257: The Decimal construct now accepts a float instance directly,
5115 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005116
5117 >>> Decimal(1.1)
5118 Decimal('1.100000000000000088817841970012523233890533447265625')
5119
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005120- collections.Counter() now supports a subtract() method.
5121
Georg Brandlfee0f442010-05-22 21:26:21 +00005122- The functools module now has a total_ordering() class decorator to simplify
5123 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005124
Georg Brandlfee0f442010-05-22 21:26:21 +00005125- The functools module also adds cmp_to_key() as a tool to transition old-style
5126 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005127
Georg Brandlfee0f442010-05-22 21:26:21 +00005128- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5129 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005130
Georg Brandlfee0f442010-05-22 21:26:21 +00005131- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5132 InvalidOperation instead of returning False. (Comparisons involving a quiet
5133 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5134 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005135
Georg Brandlfee0f442010-05-22 21:26:21 +00005136- Issue #2531: Comparison operations between floats and Decimal instances now
5137 return a result based on the numeric values of the operands; previously they
5138 returned an arbitrary result based on the relative ordering of id(float) and
5139 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005140
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005141- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005142 argument `-` which tells it to read files to compile from stdin. Each line is
5143 read on demand and the named file is compiled immediately. (Original patch by
5144 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005145
Georg Brandlfee0f442010-05-22 21:26:21 +00005146- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00005149- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5150 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005151 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005152
Georg Brandlfee0f442010-05-22 21:26:21 +00005153- Comparisons using one of <, <=, >, >= between a complex instance and a
5154 Fractions instance now raise TypeError instead of returning True/False. This
5155 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5156 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005157

Georg Brandlfee0f442010-05-22 21:26:21 +00005263 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5264 inconsistent: __int__ was used for some integer codes but not for others, and
5265 the set of integer codes for which it was used differed between native packing
5266 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005574 file position when calling `truncate()`. It would previously change the file
5575 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005576 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5577

5579 class used to represent files stored inside an archive. The new
5580 implementation is significantly faster and can be wrapped in a
5581 ``io.BufferedReader`` object for more speedups. It also solves an issue
5582 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5583 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00005593- Issue #7748: Since unicode values are supported for some metadata options in
5594 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5595 encoded string for them. This ensures that the upload and register commands
5596 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00005866- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5867 decimal string that's guaranteed to round back to x under correct rounding
5868 (with round-half-to-even rounding mode). Previously it gave a string based on
5869 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5870 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5871 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005872
Georg Brandlba83f822010-03-14 09:50:54 +00005873- Issue #7117: On almost all platforms: float-to-string and string-to-float
5874 conversions within Python are now correctly rounded. Places these conversions
5875 occur include: str for floats and complex numbers; the float and complex
5876 constructors; old-style and new-style numeric formatting; serialization and
5877 deserialization of floats and complex numbers using marshal, pickle and json;
5878 parsing of float and imaginary literals in Python code; Decimal-to-float
5879 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005880
Georg Brandlba83f822010-03-14 09:50:54 +00005881 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5882 providing correctly-rounded strtod and dtoa C functions. This code is
5883 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5884 the C compiler. There may be a small number of platforms on which correct
5885 operation of this code cannot be guaranteed, so the code is not used: notably,
5886 this applies to platforms where the C double format is not IEEE 754 binary64,
5887 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5888 and Python's configure script is unable to determine how to change the FPU
5889 precision. On these platforms conversions use the platform strtod and dtoa,
5890 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005892- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5893 uses the correctly-rounded string <-> float conversions described above (when
5894 available), and so produces correctly rounded results that will display nicely
5895 under the float repr. There are two related small changes: (1) round now
5896 accepts any class with an ``__index__()`` method for its second argument (but
5897 no longer accepts floats for the second argument), and (2) an excessively
5898 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5899 raises an exception.

6048 but with at least one decimal point and with a default precision
6049 of 12. Previously, the behavior the same but with a default precision of 6.
6050 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandl29c6a282009-04-05 20:23:13 +00006161- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00006162 were suppressing all exceptions. These include list(), filter(), map(),

6164
Benjamin Peterson596d3062009-01-19 15:42:23 +00006165- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00006192- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
6193 existing .py counterpart, override the co_filename attributes of all code
6194 objects if the original filename is obsolete (which can happen if the file has

6236 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6237 instances. On a typical machine this saves 3 bytes of memory (on average) per
6238 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006240- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

6242 instead of throwing a MemoryError.
6243
Georg Brandlba83f822010-03-14 09:50:54 +00006244- Issue #3689: The list reversed iterator now supports __length_hint__ instead

6249
Georg Brandlba83f822010-03-14 09:50:54 +00006250- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6251 file objects with closefd=False. The file descriptor is still kept open but
6252 the file object behaves like a closed file. The ``FileIO`` object also got a
6253 new readonly attribute ``closefd``.

6272
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006273- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00006274 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00006276- On windows, ``os.chdir()`` given unicode was not working if
6277 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6278 this code path is really executed because I cannot move to such directory on
6279 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00006280
Georg Brandlba83f822010-03-14 09:50:54 +00006281- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6282 element is temporarily replaced with an equivalent frozenset. But the
6283 eventual KeyError would always report the empty ``frozenset()`` as the missing
6284 key. Now it correctly refers to the initial element.

6303
Walter Dörwalded960ac2009-05-03 22:36:33 +00006304- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6305 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6306 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6307 of using the replace error handler in PyUnicode_DecodeUTF8().
6308
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006309- Issue #3739: The unicode-internal encoder now reports the number of characters

6311
Georg Brandlba83f822010-03-14 09:50:54 +00006312- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6313 allocator will be automatically disabled when running under Valgrind. This
6314 gives improved memory leak detection when running under Valgrind, while taking
6315 advantage of pymalloc at other times.

6386 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00006387 __main__.py file. This allows applications that run other Python scripts to
6388 support the same flexibility as the CPython command line itself.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007706- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7707 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7708 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7709 ``printf`` function, whereas PyString_FromFormat has an independent
7710 implementation and uses "%zd" on all platforms for size_t values.
7711 This makes a difference on win64, where ``printf`` needs "%Id" to display
7712 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00007732 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

7736 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007807 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7808 for catch_warnings() also led to an improvement in the raising of a
7809 DeprecationWarning related to warnings.warn_explicit().
7810
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007811- The deprecation warnings for the old camelCase threading API were removed.

7832 _check_logger_class from multiprocessing.
7833
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007834- Issue #2975: When compiling several extension modules with Visual Studio 2008
7835 from the same python interpreter, some environment variables would grow
7836 without limit.
7837
Benjamin Peterson37346b22008-08-23 20:27:43 +00007838- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7839 exploitation of poor argument checking.
7840
Gerhard Häringef2276b2008-09-12 13:54:06 +00007841- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
7842
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00007843- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
7844 remaining ones have "pysqlite_" prefix.
7845
Gerhard Häringe6872eb2008-09-12 22:33:22 +00007846- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

7854 wrapper for warnings.catch_warnings() that makes it easier to check
7855 that expected warning messages are being reported.
7856

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007875What's New in Python 2.6 beta 3?
7876================================
7877
Barry Warsaw07a4a382008-08-21 01:15:08 +00007878*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007879
7880Core and Builtins
7881-----------------
7882
Guido van Rossumf8402962008-08-20 15:01:50 +00007883- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7884 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7885 extensions do not automatically benefit from the class attribute
7886 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7887 to their tp_flags field if they care. This is a backwards
7888 compatibility feature; in 3.0, all types will use the cache by
7889 default.
7890
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007891- Keyword arguments can now follow starred arguments. (``f(a, *args,
7892 keyword=23)`` is now valid syntax.)
7893
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007894- ctypes function pointers that are COM methods have a boolean True
7895 value again.
7896
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007897- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7898 by denying s# to parse objects that have a releasebuffer procedure,
7899 and introducing s*.
7900
Georg Brandl1e13ea92008-08-11 09:07:59 +00007901- Issue #3537: Fix an assertion failure when an empty but presized dict
7902 object was stored in the freelist.
7903
Mark Dickinsonb6467572008-08-04 21:30:09 +00007904- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7905 ValueError consistently across platforms.
7906
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007907- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7908 (64bit Unix, for example), unichr() would truncate its argument and return
7909 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7910
Neal Norwitze7d8be82008-07-31 17:17:14 +00007911- Apply security patches from Apple.
7912
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007913- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7914 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7915
Antoine Pitrou92f82162008-07-25 22:22:08 +00007916- Issue #1819: function calls with several named parameters are now on
7917 average 35% faster (as measured by pybench).
7918
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007919- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7920 the python debugger steps into a class statement: the free variables (local
7921 variables defined in an outer scope) would be deleted from the outer scope.
7922
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007923- Issue #2620: Overflow checking when allocating or reallocating memory
7924 was not always being done properly in some python types and extension
7925 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7926 all been updated to perform better checks and places in the code that
7927 would previously leak memory on the error path when such an allocation
7928 failed have been fixed.
7929
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007930Library
7931-------
7932

7934
Benjamin Petersone977ad42008-08-20 01:42:01 +00007935- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7936 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7937
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007938- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7939 version reported by these tools does not necessarily follow the python
7940 version numbering scheme, so the module is less strict when parsing it.
7941
Nick Coghlanf70385a2008-08-18 12:42:46 +00007942- Issue #2235: Added Py3k warnings for types which will become unhashable
7943 under the stricter __hash__ inheritance rules in 3.0. Several types
7944 which did not meet the rules for hash invariants and were already
7945 unhashable in 3.0 have now been explicitly flagged as unhashable in
7946 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7947 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7948
Brett Cannon88f801d2008-08-18 00:46:22 +00007949- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7950 imported into the module but exposed as part of the module's API.
7951
Brett Cannon7b96f072008-08-18 00:41:11 +00007952- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007956- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7957
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007958- Issue #3575: Incremental decoder's decode function now takes bytearray
7959 by using 's*' instead of 't#'.
7960
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007961- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007962 fails unicode conversion on 2nd parameter. (windows only)
7963
Georg Brandl222e2082010-08-01 22:27:39 +00007964- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007965 in a redirect.
7966

Brett Cannon721b1452008-08-16 22:00:27 +00007968 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007969
Facundo Batistaeb90b782008-08-16 14:44:07 +00007970- Issue #2776: fixed small issue when handling an URL with double slash
7971 after a 302 response in the case of not going through a proxy.
7972
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007973- Issue #2676: in the email package, content-type parsing was hanging on
7974 pathological input because of quadratic or exponential behaviour of a
7975 regular expression.
7976
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007977- Issue #3476: binary buffered reading through the new "io" library is now
7978 thread-safe.
7979
Brett Cannonbf3157b2008-08-14 05:00:03 +00007980- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7981 since mimetools itself is deprecated. Because modules are cached, all
7982 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7983
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007984- Issue #3134: shutil referenced undefined WindowsError symbol.
7985
Robert Schuppenies14646332008-08-10 11:01:53 +00007986- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7987 menu entries were not deleted.
7988
Brett Cannon83e81842008-08-09 23:30:55 +00007989- Copied the implementation of reduce() to _functools.reduce() to have a
7990 version that did not raise a DeprecationWarning under -3.
7991
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007992- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7993 a MemoryError rather than silently stop the iteration.
7994
Guido van Rossum59ce9012008-08-09 14:55:34 +00007995- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7996 to _sre.compile() will now be rejected. This should not affect anybody
7997 since the re.compile() function never generates invalid re-bytecode.
7998
Skip Montanaroa032bf42008-08-08 22:52:51 +00007999- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8000 upon first access it can be automatically initialized from the csv file if
8001 it wasn't initialized during instantiation.
8002
Brett Cannon3aa2a492008-08-06 22:28:09 +00008003- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8004 the reload() built-in has been removed.
8005
Brett Cannon7e30b672008-08-04 21:52:25 +00008006- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008007 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00008018 asking for a specific length. This problem only affected files opened
8019 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008020

8065 regarding lack of coverage of new-style classes have also been
8066 removed, since the coverage is now fairly reasonable.

8076
Georg Brandl3e483f62008-07-16 22:57:41 +00008077- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8078 its methods now allow for items objects that can be converted to
8079 an integer using operator.index().
8080
Mark Dickinson64b7e502008-07-16 09:40:03 +00008081- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8082 produced a ValueError instead of giving the correct float.
8083
Eric Smitha5fa5a22008-07-16 00:11:49 +00008084- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Nick Coghlan6d6bd442008-07-15 15:40:22 +00008091- Issue #2235: __hash__ is once again inherited by default. To allow
8092 collections.Hashable to remain meaningful in the presence of the
8093 default hash implementation (object.__hash__), it is now possible
8094 to explicit block inheritance of hash by setting __hash__=None at
8095 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8096 level.
8097
Nick Coghlanb028f502008-07-13 14:52:36 +00008098- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8099 the parent module cannot be found while performing an absolute import.
8100 This means that an incorrectly defined __package__ attribute will
8101 now only prevent relative imports in that module rather than causing
8102 all imports from that module to fail.

8115
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008116- Issue #3004: Minor change to slice.indices(): the start and stop
8117 arguments are now treated identically, making the behaviour easier
8118 to describe and understand. For example, slice(None, -10,
8119 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8120 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8121 10, -1).

8164 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008165 wrong because the actual transmitted size could differ from the

8572 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008573 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008574
8575 This is controlled by the configure argument ``--with-universal-archs``:
8576
8577 - ``--with-universal-archs=all``: install 4-way universal
8578
8579 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8580
8581 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8582
8583 This option should be used in combination with ``--enable-universalsdk=``.
8584
8585 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

8621 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00008622
Christian Heimese74c8f22008-04-19 02:23:57 +00008623- Added kill, terminate and send_signal(sig) to subprocess.Popen.
8624

Gregory P. Smith671c5d92008-04-09 18:18:43 +00008633
Georg Brandl3ee81df2008-05-17 18:14:43 +00008634- Issue #1631171: Re-implement the 'warnings' module in C (the
8635 original Python code has been kept as backup). This will allow for
8636 using the 'warning's machinery in such places as the parser where
8637 use of pure Python code is not possible. Both the ``showarning()``
8638 and ``formatwarning()`` gain an optional 'line' argument which is
8639 not called by default for backwards-compatibility reasons. Setting
8640 ``warnings.showwarning()`` to an implementation that lacks support
8641 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008704- Issue #2550: The approach used by client/server code for obtaining
8705 ports to listen on in network-oriented tests has been refined in an
8706 effort to facilitate running multiple instances of the entire
8707 regression test suite in parallel without issue.
8708 test_support.bind_port() has been fixed such that it will always
8709 return a unique port -- which wasn't always the case with the
8710 previous implementation, especially if socket options had been set
8711 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8712 new implementation of bind_port() will actually raise an exception
8713 if it is passed an AF_INET/SOCK_STREAM socket with either the
8714 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8715 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8716 the socket it's been passed. This currently only applies to
8717 Windows. This option prevents any other sockets from binding to the
8718 host/port we've bound to, thus removing the possibility of the
8719 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8720 when a second SOCK_STREAM socket binds and accepts to a host/port
8721 that's already been bound by another socket. The optional preferred
8722 port parameter to bind_port() has been removed. Under no
8723 circumstances should tests be hard coding ports!
8724
8725 test_support.find_unused_port() has also been introduced, which will
8726 pass a temporary socket object to bind_port() in order to obtain an
8727 unused port. The temporary socket object is then closed and
8728 deleted, and the port is returned. This method should only be used
8729 for obtaining an unused port in order to pass to an external program
8730 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8731 a parameter to a server-oriented class that doesn't give you direct
8732 access to the underlying socket used.
8733
8734 Finally, test_support.HOST has been introduced, which should be used
8735 for the host argument of any relevant socket calls (i.e. bind and
8736 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008737
8738 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008739 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008740 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8741 test_asynchat and test_socket_ssl.
8742
Georg Brandl3ee81df2008-05-17 18:14:43 +00008743 It is now possible for multiple instances of the regression test
8744 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009023- Added the future_builtins module, which contains hex() and oct().
9024 These are the PEP 3127 version of these functions, designed to be
9025 compatible with the hex() and oct() builtins from Python 3.0. They
9026 differ slightly in their output formats from the existing, unchanged
9027 Python 2.6 builtins. The expected usage of the future_builtins
9028 module is:
9029 from future_builtins import hex, oct
9030
Eric Smith7ef40bf2008-02-20 23:34:22 +00009031- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9032 exponents for exponents with absolute value < 100. Follows C99
9033 standard. This is a change on Windows, which would use 3 digits.
9034 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9035 so that any alterations it does to the resulting string will be
9036 available in stringlib/formatter.h (for float.__format__).
9037
Eric Smith5a3c1352008-02-19 13:21:56 +00009038- Implemented PEP 3101, Advanced String Formatting. This adds a new
9039 builtin format(); a format() method for str and unicode; a
9040 __format__() method to object, str, unicode, int, long, float, and
9041 datetime; the class string.Formatter; and the C API
9042 PyObject_Format().
9043
Georg Brandl3ee81df2008-05-17 18:14:43 +00009044- Fixed several potential crashes, all caused by specially crafted
9045 __del__ methods exploiting objects in temporarily inconsistent
9046 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009055- Clear all free lists during a gc.collect() of the highest generation
9056 in order to allow pymalloc to free more arenas. Python may give back
9057 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009058
Georg Brandl3ee81df2008-05-17 18:14:43 +00009059- Issue #2045: Fix an infinite recursion triggered when printing a
9060 subclass of collections.defaultdict, if its default_factory is set
9061 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009062
Christian Heimesf75dbef2008-02-08 00:11:31 +00009063- Fixed a minor memory leak in dictobject.c. The content of the free
9064 list was not freed on interpreter shutdown.
9065
Georg Brandl21e99f42010-03-07 15:23:59 +00009066- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00009068
Georg Brandl3ee81df2008-05-17 18:14:43 +00009069- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9070 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009071 to compact the internal free lists of pre-allocted ints and floats.
9072
Georg Brandl3ee81df2008-05-17 18:14:43 +00009073- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9074 calls. Python expected the return type int but the fork familie
9075 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009089- Patch #1473257: generator objects gain a gi_code attribute. This is
9090 the same object as the func_code attribute of the function that
9091 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009092
Georg Brandl3ee81df2008-05-17 18:14:43 +00009093- Issue #1920: "while 0" statements were completely removed by the
9094 compiler, even in the presence of an "else" clause, which is
9095 supposed to be run when the condition is false. Now the compiler
9096 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009097
Guido van Rossumeead05f2008-01-24 18:21:02 +00009098- A few crashers fixed: weakref_in_del.py (issue #1377858);
9099 loosing_dict_ref.py (issue #1303614, test67.py);
9100 borrowed_ref_[34].py (not in tracker).
9101
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009102- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009103 suppressed while an extension is loaded by calling SetErrorMode in

9105
Georg Brandl3ee81df2008-05-17 18:14:43 +00009106- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009107 several extension methods and modules do not work without unicode
9108 support.
9109
Georg Brandl26543b12008-01-21 18:36:51 +00009110- Issue #1882: when compiling code from a string, encoding cookies in the

9112
Georg Brandl14404b62008-01-19 19:27:05 +00009113- Issue #1679: "0x" was taken as a valid integer literal.
9114
Georg Brandl6caad7d2008-01-26 14:19:22 +00009115- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009116 added.
9117
Christian Heimesc94e2b52008-01-14 04:13:37 +00009118- sys.float_info / PyFloat_GetInfo: The floating point information
9119 object was converted from a dict to a specialized structseq object.
9120
Georg Brandl3ee81df2008-05-17 18:14:43 +00009121- Patch #1816: Added sys.flags structseq. It exposes the status of
9122 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009123
Georg Brandl3ee81df2008-05-17 18:14:43 +00009124- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00009153- Compiler now generates simpler and faster code for dictionary
9154 literals. The oparg for BUILD_MAP now indicates an estimated
9155 dictionary size. There is a new opcode, STORE_MAP, for adding
9156 entries to the dictionary.

9186 file can now be directly executed by passing their name to the
9187 interpreter. The directory/zipfile is automatically inserted as the
9188 first entry in sys.path.

9199
Georg Brandl21e99f42010-03-07 15:23:59 +00009200- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009201 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9202 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009203
Georg Brandl3ee81df2008-05-17 18:14:43 +00009204- Issue #1686386: Tuple's tp_repr did not take into account the
9205 possibility of having a self-referential tuple, which is possible
9206 from C code. Nor did object's tp_str consider that a type's tp_str
9207 could do something that could lead to an inifinite recursion.
9208 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9209 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009210
Georg Brandl3ee81df2008-05-17 18:14:43 +00009211- Issue #1164: It was possible to trigger deadlock when using the
9212 'print' statement to write to a file since the GIL was not released
9213 as needed. Now PyObject_Print() does the right thing along with
9214 various tp_print implementations of the built-in types and those in
9215 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009216
Georg Brandl3ee81df2008-05-17 18:14:43 +00009217- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00009224- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009225 PyObject_Call() never calling back out to Python code to trigger
9226 recursion depth updates/checks. Required the creation of a static
9227 RuntimeError instance in case normalizing an exception put the
9228 recursion check value past its limit. Fixes crashers
9229 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00009244- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009245 __*__ attributes. (Some already existed, e.g., __doc__ and
9246 __name__.)

9252 calls.
9253
Collin Winter62903052007-05-18 23:11:24 +00009254- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009255 "except E as target:". This is to provide forwards compatibility
9256 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009263- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009264 setting a plain string, ie don't expand to single letter identifiers.
9265
Raymond Hettinger13936692007-04-11 18:40:58 +00009266- Request #1191699: Slices can now be pickled.
9267
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009268- Request #1193128: str.translate() now allows a None argument for
9269 translations that only remove characters without re-mapping the
9270 remaining characters.
9271
Georg Brandl5cb76c12007-03-21 09:00:39 +00009272- Patch #1682205: a TypeError while unpacking an iterable is no longer

9276
Guido van Rossum143b5642007-03-23 04:58:42 +00009277- Bug #1683368: The object.__init__() and object.__new__() methods are
9278 now stricter in rejecting excess arguments. The only time when
9279 either allows excess arguments is when it is not overridden and the
9280 other one is. For backwards compatibility, when both are
9281 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009282 warning later). Also, type.__init__() insists on the same signature
9283 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009284
Georg Brandl3ee81df2008-05-17 18:14:43 +00009285- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9286 object to complex using its __complex__() method before falling back
9287 to the __float__() method. Therefore, the functions in the cmath
9288 module now can operate on objects that define a __complex__()
9289 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009291- Patch #1623563: allow __class__ assignment for classes with
9292 __slots__. The old and the new class are still required to have the
9293 same slot names.

9300 its type.

9306
Georg Brandl7b9c5552007-03-12 14:30:05 +00009307- Bug #1678647: write a newline after printing an exception in any
9308 case, even when converting the value to a string failed.
9309
Georg Brandl871f1bc2007-03-12 13:17:36 +00009310- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009311 its argument, if it exists. If not, it will work like before. This
9312 allows customizing the output of dir() in the presence of a
9313 __getattr__().

9317
Georg Brandl3ee81df2008-05-17 18:14:43 +00009318- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00009321- Patch #1491866: change the complex() constructor to allow
9322 parthensized forms. This means complex(repr(x)) now works instead of
9323 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009324
Georg Brandlaa2321b2007-03-07 00:40:28 +00009325- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009326 makes the filenames the warning module prints much more sensible
9327 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00009340- Patch #1674228: when assigning a slice (old-style), check for the
9341 sq_ass_slice instead of the sq_slice slot.
9342
Georg Brandl3ee81df2008-05-17 18:14:43 +00009343- When printing an unraisable error, don't print exceptions. before
9344 the name. This duplicates the behavior whening normally printing
9345 exceptions.

Georg Brandl4e933132006-09-06 20:05:58 +00009428- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00009486- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl92a6bae2007-03-13 17:43:32 +00009911- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009912 are set for invalid interpolation sequences that would lead to

Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010254 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +000010256 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010355- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010356 time so that opening a database previously created with the DB_DUP
10357 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10358 opens. Specifically: dictionary assignment to a DB object will
10359 replace all values for a given key when the database allows
10360 duplicate values. DB users should use DB.put(k, v) when they want
10361 to store duplicates; not DB[k] = v.

10370 behavior of quoting dots if they are the second character of any
10371 line.

10704 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010705
Georg Brandl3ee81df2008-05-17 18:14:43 +000010706- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10707 to ``PyTuple_SetItem``, it can be used to populate a brand new

10722 of w# format code incorrectly truncated the length to an int, even
10723 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10724 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010725

10745 (relevant to strings and sequences of more than 2**31 items).
10746
10747- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10748 outside of pystate.c and should not be necessary.
10749
Georg Brandl3ee81df2008-05-17 18:14:43 +000010750- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10751 absolute imports. In earlier versions they might have used relative
10752 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010753
Georg Brandl3ee81df2008-05-17 18:14:43 +000010754- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10755 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010763- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10764 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10765 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10766 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010767

Georg Brandl3ee81df2008-05-17 18:14:43 +000010780- Removed the macfs module. It had been deprecated since Python 2.5.
10781 This lead to the deprecation of macostools.touched() as it relied
10782 solely on macfs and was a no-op under OS X.
