1406 32-bit-only installer Pythons on systems with Xcode 4 (currently
1407 OS X 10.8, 10.7, and optionally 10.6).
1408 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1409 * Since Xcode 4 removes ppc support, extension module builds now
1410 check for ppc compiler support and by default remove ppc and
1411 ppc64 archs when they are not available.
1412 * Extension module builds now revert to using system installed
1413 headers and libs (/usr and /System/Library) if the SDK used
1414 to build the interpreter is not installed or has moved.
1415 * Try to avoid building extension modules with deprecated
1416 and problematic Apple llvm-gcc compiler. If original compiler
1417 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001768- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1769 int.__pow__. These overflow checks were causing int.__pow__ to produce
1770 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001771 compiler optimizing the check away. Also fix similar overflow checks
1772 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1773 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001841- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001842 has left two versions of customize_compiler, the original in
1843 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001848- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1849 Distutils-based packages with C extension modules may fail because
1850 Apple has removed gcc-4.2, the version used to build python.org
1851 64-bit/32-bit Pythons. If the user does not explicitly override
1852 the default C compiler by setting the CC environment variable,
1853 Distutils will now attempt to compile extension modules with clang
1854 if gcc-4.2 is required but not found. Also as a convenience, if
1855 the user does explicitly set CC, substitute its value as the default
1856 compiler in the Distutils LDSHARED configuration variable for OS X.
1857 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1858 SDK, neither of which are available in Xcode 4. This change does not
1859 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002109- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2110 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2111 interpreter process. This could cause failures in non-Distutils subprocesses
2112 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002113 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002114 deployment target only in the environment of each build subprocess. It is
2115 still possible to globally override the default by setting
2116 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2117 greater or equal to the default value, the value with which the interpreter
2118 was built.

2148 the ticker doesn't have to wind down to zero from the old starting point
2149 before the new interval takes effect. And if the user increases the
2150 interval, it makes sure the new limit takes effect right away rather have an

3130
Raymond Hettinger20397532010-09-12 02:11:45 +00003131- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3132 This prevents user-created self-referencing ordered dictionaries from
3133 becoming permanently uncollectable GC garbage. The downside is that
3134 removing __del__ means that the internal doubly-linked list has to wait for
3135 GC collection rather than freeing memory immediately when the refcnt drops
3136 to zero.

3141
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003142- Issue #9792: In case of connection failure, socket.create_connection()

3144 to fetch the original errno, or to filter timeout errors. Now the
3145 original error is re-raised.

3593
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003594- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3595 start byte and the continuation byte(s) are now considered invalid, instead
3596 of the number of bytes specified by the start byte.
3597 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3598 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3599 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3600 Previous versions returned a single u'\ufffd'.

3606 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003608- Issue #8748: Fix two issues with comparisons between complex and integer
3609 objects. (1) The comparison could incorrectly return True in some cases
3610 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3611 (2) The comparison raised an OverflowError for large integers, leading
3612 to unpredictable exceptions when combining integers and complex objects
3613 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003615- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00004493 file position when calling `truncate()`. It would previously change the file
4494 position to the given argument, which goes against the tradition of

4498 class used to represent files stored inside an archive. The new
4499 implementation is significantly faster and can be wrapped in a
4500 ``io.BufferedReader`` object for more speedups. It also solves an issue
4501 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004592- The ``__complex__()`` method is now looked up on the class of instances to
4593 make it consistent with other special methods.

4597
Mark Dickinson1b34d252010-01-01 17:27:30 +00004598- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004599 DeprecationWarning when passed a float argument where an integer was expected.
4600 These functions and methods now raise TypeError instead. The majority of the
4601 effects of this change are in the extension modules, but some core functions
4602 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4603 and many unicode/str methods.

4619 internal representation of a long.

4715 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4716 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4717 float arguments for integer format codes (other than 'L'): previously an
4718 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4719 TypeError. For the 'L' format code (which previously had no warning) there is
4720 now a DeprecationWarning.

4768 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4769 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004770
Georg Brandlba83f822010-03-14 09:50:54 +00004771- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4772 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004773
Georg Brandlba83f822010-03-14 09:50:54 +00004774- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4775 1e-100 used to raise OverflowError, but now gives the requested 120
4776 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004784
Georg Brandlba83f822010-03-14 09:50:54 +00004785- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4786 decimal string that's guaranteed to round back to x under correct rounding
4787 (with round-half-to-even rounding mode). Previously it gave a string based on
4788 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4789 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4790 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004791
Georg Brandlba83f822010-03-14 09:50:54 +00004792- Issue #7117: On almost all platforms: float-to-string and string-to-float
4793 conversions within Python are now correctly rounded. Places these conversions
4794 occur include: str for floats and complex numbers; the float and complex
4795 constructors; old-style and new-style numeric formatting; serialization and
4796 deserialization of floats and complex numbers using marshal, pickle and json;
4797 parsing of float and imaginary literals in Python code; Decimal-to-float
4798 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004799
Georg Brandlba83f822010-03-14 09:50:54 +00004800 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4801 providing correctly-rounded strtod and dtoa C functions. This code is
4802 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4803 the C compiler. There may be a small number of platforms on which correct
4804 operation of this code cannot be guaranteed, so the code is not used: notably,
4805 this applies to platforms where the C double format is not IEEE 754 binary64,
4806 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4807 and Python's configure script is unable to determine how to change the FPU
4808 precision. On these platforms conversions use the platform strtod and dtoa,
4809 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004810
Georg Brandlba83f822010-03-14 09:50:54 +00004811- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4812 uses the correctly-rounded string <-> float conversions described above (when
4813 available), and so produces correctly rounded results that will display nicely
4814 under the float repr. There are two related small changes: (1) round now
4815 accepts any class with an ``__index__()`` method for its second argument (but
4816 no longer accepts floats for the second argument), and (2) an excessively
4817 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4818 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004959- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00004960
Georg Brandlba83f822010-03-14 09:50:54 +00004961 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4962 (2) parsing of strings representing infinities and nans was locale aware; and
4963 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004965- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4966 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4967 but with at least one decimal point and with a default precision
4968 of 12. Previously, the behavior the same but with a default precision of 6.
4969 This more closely matches ``str()``, and reduces surprises when adding
4970 alignment flags to the empty presentation type. This also affects the new
4971 complex.__format__ in the same way.
4972
4973- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4974 classtype's, even if it was None. property now inserts the __doc__ into the

5045 internal representation of integers, for performance reasons. Base 2**30 is
5046 enabled by default on 64-bit machines. Add --enable-big-digits option to

5197 this code path is really executed because I cannot move to such directory on

5202 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005223- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5224 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5225 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5226 of using the replace error handler in PyUnicode_DecodeUTF8().
5227
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005228- Issue #3739: The unicode-internal encoder now reports the number of characters

5230
Georg Brandlba83f822010-03-14 09:50:54 +00005231- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5232 allocator will be automatically disabled when running under Valgrind. This
5233 gives improved memory leak detection when running under Valgrind, while taking
5234 advantage of pymalloc at other times.

6404 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6405 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006602- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6603
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006604- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6605 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6606 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6607 ``printf`` function, whereas PyString_FromFormat has an independent
6608 implementation and uses "%zd" on all platforms for size_t values.
6609 This makes a difference on win64, where ``printf`` needs "%Id" to display
6610 64bit values.
6611
Benjamin Peterson97179b02008-09-09 20:55:01 +00006612- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6613 error.
6614
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006615- Issue #3777: long() applied to a float object now always return a long
6616 object; previously an int would be returned for small values. the __long__
6617 method is allowed to return either an int or a long, but the behaviour of
6618 float objects should not change to respect backward compatibility.
6619
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006620- Issue #3751: str.rpartition would perform a left-partition when called with
6621 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006626 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006627 was correctly parsed but parsing of subsequent arguments failed.
6628
Vinay Sajip35e3b032008-09-01 14:33:59 +00006629- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006630 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6631 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6632 when given a tuple of classes as second argument, were looking up
6633 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6634 type object.
6635
Neal Norwitz18aa3882008-08-24 05:04:52 +00006636- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006705 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6706 for catch_warnings() also led to an improvement in the raising of a

6779-----------------
6780
Guido van Rossumf8402962008-08-20 15:01:50 +00006781- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6782 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6783 extensions do not automatically benefit from the class attribute
6784 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6785 to their tp_flags field if they care. This is a backwards
6786 compatibility feature; in 3.0, all types will use the cache by
6787 default.
6788
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006789- Keyword arguments can now follow starred arguments. (``f(a, *args,
6790 keyword=23)`` is now valid syntax.)
6791
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006792- ctypes function pointers that are COM methods have a boolean True
6793 value again.
6794
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006795- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6796 by denying s# to parse objects that have a releasebuffer procedure,
6797 and introducing s*.
6798
Georg Brandl1e13ea92008-08-11 09:07:59 +00006799- Issue #3537: Fix an assertion failure when an empty but presized dict
6800 object was stored in the freelist.
6801
Mark Dickinsonb6467572008-08-04 21:30:09 +00006802- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6803 ValueError consistently across platforms.
6804
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006805- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6806 (64bit Unix, for example), unichr() would truncate its argument and return
6807 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6808
Neal Norwitze7d8be82008-07-31 17:17:14 +00006809- Apply security patches from Apple.
6810
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006811- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6812 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6813
Antoine Pitrou92f82162008-07-25 22:22:08 +00006814- Issue #1819: function calls with several named parameters are now on
6815 average 35% faster (as measured by pybench).
6816
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006817- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6818 the python debugger steps into a class statement: the free variables (local
6819 variables defined in an outer scope) would be deleted from the outer scope.
6820
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006821- Issue #2620: Overflow checking when allocating or reallocating memory
6822 was not always being done properly in some python types and extension
6823 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6824 all been updated to perform better checks and places in the code that
6825 would previously leak memory on the error path when such an allocation
6826 failed have been fixed.

6832
Benjamin Petersone977ad42008-08-20 01:42:01 +00006833- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of

6835
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006836- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6837 version reported by these tools does not necessarily follow the python

6839
Nick Coghlanf70385a2008-08-18 12:42:46 +00006840- Issue #2235: Added Py3k warnings for types which will become unhashable
6841 under the stricter __hash__ inheritance rules in 3.0. Several types
6842 which did not meet the rules for hash invariants and were already
6843 unhashable in 3.0 have now been explicitly flagged as unhashable in
6844 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6845 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6846

6902 the reload() built-in has been removed.
6903

Antoine Pitroude781a42008-08-09 12:43:23 +00006916 asking for a specific length. This problem only affected files opened

6959 interaction with the tp_hash slot (added in 2.6b2) are now documented
6960
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006961- Issue #643841: The language reference now provides more detailed
6962 coverage of the lookup process for special methods. The disclaimers
6963 regarding lack of coverage of new-style classes have also been
6964 removed, since the coverage is now fairly reasonable.

6968================================
6969
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006970*Release date: 17-Jul-2008*
6971
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006972Core and Builtins
6973-----------------
6974
Georg Brandl3e483f62008-07-16 22:57:41 +00006975- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6976 its methods now allow for items objects that can be converted to
6977 an integer using operator.index().
6978
Mark Dickinson64b7e502008-07-16 09:40:03 +00006979- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6980 produced a ValueError instead of giving the correct float.
6981
Eric Smitha5fa5a22008-07-16 00:11:49 +00006982- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6983 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6984
Mark Dickinson7103aa42008-07-15 19:08:33 +00006985- Issue #3008: the float type has a new instance method 'float.hex'
6986 and a new class method 'float.fromhex' to convert floating-point
6987 numbers to and from hexadecimal strings, respectively.
6988
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006989- Issue #2235: __hash__ is once again inherited by default. To allow
6990 collections.Hashable to remain meaningful in the presence of the
6991 default hash implementation (object.__hash__), it is now possible
6992 to explicit block inheritance of hash by setting __hash__=None at
6993 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6994 level.
6995
Nick Coghlanb028f502008-07-13 14:52:36 +00006996- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6997 the parent module cannot be found while performing an absolute import.
6998 This means that an incorrectly defined __package__ attribute will
6999 now only prevent relative imports in that module rather than causing
7000 all imports from that module to fail.
7001
Nick Coghlan14ff9942008-07-08 14:21:42 +00007002- Issue #2517: Allow unicode messages in Exceptions again by correctly
7003 bypassing the instance dictionary when looking up __unicode__ on
7004 new-style classes.
7005
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007006- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7007 set to a custom object whose write() method happens to install
7008 another file in sys.stdout.
7009
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007010- Issue #3088: Corrected a race condition in classes derived from
7011 threading.local: the first member set by a thread could be saved in
7012 another thread's dictionary.
7013
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007014- Issue #3004: Minor change to slice.indices(): the start and stop
7015 arguments are now treated identically, making the behaviour easier
7016 to describe and understand. For example, slice(None, -10,
7017 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7018 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7019 10, -1).
7020
Georg Brandl278fc502008-07-19 12:46:12 +00007021- Issue #3219: Calling a function with repeated keyword arguments,
7022 f(a=2, a=23), would not cause a syntax error. This was a regression
7023 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007024
Georg Brandl278fc502008-07-19 12:46:12 +00007025- Issue #2862: Make int and float freelist management consistent with
7026 other freelists. Changes their CompactFreeList apis into
7027 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007032- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7033 api functions without holding the GIL, which could lead to a fatal
7034 error when they failed.
7035
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007036- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007061- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7062 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007063 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007064 content-length. The problem had been corrected in the 2.4 branch, but never
7065 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007080- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7082
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007083- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00007469- On MacOS X it is now possible to install the framework in 64-bit
7470 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007471 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007472
7473 This is controlled by the configure argument ``--with-universal-archs``:
7474
7475 - ``--with-universal-archs=all``: install 4-way universal
7476
7477 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7478
7479 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7480
7481 This option should be used in combination with ``--enable-universalsdk=``.
7482
7483 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 +00007532- Issue #1631171: Re-implement the 'warnings' module in C (the
7533 original Python code has been kept as backup). This will allow for
7534 using the 'warning's machinery in such places as the parser where
7535 use of pure Python code is not possible. Both the ``showarning()``
7536 and ``formatwarning()`` gain an optional 'line' argument which is
7537 not called by default for backwards-compatibility reasons. Setting
7538 ``warnings.showwarning()`` to an implementation that lacks support
7539 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007602- Issue #2550: The approach used by client/server code for obtaining
7603 ports to listen on in network-oriented tests has been refined in an
7604 effort to facilitate running multiple instances of the entire
7605 regression test suite in parallel without issue.
7606 test_support.bind_port() has been fixed such that it will always
7607 return a unique port -- which wasn't always the case with the
7608 previous implementation, especially if socket options had been set
7609 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7610 new implementation of bind_port() will actually raise an exception
7611 if it is passed an AF_INET/SOCK_STREAM socket with either the
7612 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7613 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7614 the socket it's been passed. This currently only applies to
7615 Windows. This option prevents any other sockets from binding to the
7616 host/port we've bound to, thus removing the possibility of the
7617 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7618 when a second SOCK_STREAM socket binds and accepts to a host/port
7619 that's already been bound by another socket. The optional preferred
7620 port parameter to bind_port() has been removed. Under no
7621 circumstances should tests be hard coding ports!
7622
7623 test_support.find_unused_port() has also been introduced, which will
7624 pass a temporary socket object to bind_port() in order to obtain an
7625 unused port. The temporary socket object is then closed and
7626 deleted, and the port is returned. This method should only be used
7627 for obtaining an unused port in order to pass to an external program
7628 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7629 a parameter to a server-oriented class that doesn't give you direct
7630 access to the underlying socket used.
7631
7632 Finally, test_support.HOST has been introduced, which should be used
7633 for the host argument of any relevant socket calls (i.e. bind and
7634 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007635
7636 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007637 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007638 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7639 test_asynchat and test_socket_ssl.
7640
Georg Brandl3ee81df2008-05-17 18:14:43 +00007641 It is now possible for multiple instances of the regression test
7642 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007696- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007697 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7698 Plane. This affected raw unicode literals and the

7700 this case, like normal unicode literals and the 'unicode-escape'
7701 codec.

7925 Python 2.6 builtins. The expected usage of the future_builtins
7926 module is:
7927 from future_builtins import hex, oct
7928
Eric Smith7ef40bf2008-02-20 23:34:22 +00007929- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7930 exponents for exponents with absolute value < 100. Follows C99
7931 standard. This is a change on Windows, which would use 3 digits.
7932 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7933 so that any alterations it does to the resulting string will be
7934 available in stringlib/formatter.h (for float.__format__).
7935
Eric Smith5a3c1352008-02-19 13:21:56 +00007936- Implemented PEP 3101, Advanced String Formatting. This adds a new
7937 builtin format(); a format() method for str and unicode; a
7938 __format__() method to object, str, unicode, int, long, float, and
7939 datetime; the class string.Formatter; and the C API
7940 PyObject_Format().
7941
Georg Brandl3ee81df2008-05-17 18:14:43 +00007942- Fixed several potential crashes, all caused by specially crafted
7943 __del__ methods exploiting objects in temporarily inconsistent
7944 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007945
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007946- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007947 prevent a possible crash: an Abstract Base Class would try to access
7948 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007949

Georg Brandl3ee81df2008-05-17 18:14:43 +00007953- Clear all free lists during a gc.collect() of the highest generation
7954 in order to allow pymalloc to free more arenas. Python may give back
7955 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007956
Georg Brandl3ee81df2008-05-17 18:14:43 +00007957- Issue #2045: Fix an infinite recursion triggered when printing a
7958 subclass of collections.defaultdict, if its default_factory is set
7959 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007987- Patch #1473257: generator objects gain a gi_code attribute. This is
7988 the same object as the func_code attribute of the function that
7989 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007990
Georg Brandl3ee81df2008-05-17 18:14:43 +00007991- Issue #1920: "while 0" statements were completely removed by the
7992 compiler, even in the presence of an "else" clause, which is
7993 supposed to be run when the condition is false. Now the compiler
7994 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007995
Guido van Rossumeead05f2008-01-24 18:21:02 +00007996- A few crashers fixed: weakref_in_del.py (issue #1377858);

8003
Georg Brandl3ee81df2008-05-17 18:14:43 +00008004- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008005 several extension methods and modules do not work without unicode
8006 support.
8007
Georg Brandl26543b12008-01-21 18:36:51 +00008008- Issue #1882: when compiling code from a string, encoding cookies in the

8012
Georg Brandl6caad7d2008-01-26 14:19:22 +00008013- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008014 added.
8015
Christian Heimesc94e2b52008-01-14 04:13:37 +00008016- sys.float_info / PyFloat_GetInfo: The floating point information
8017 object was converted from a dict to a specialized structseq object.
8018
Georg Brandl3ee81df2008-05-17 18:14:43 +00008019- Patch #1816: Added sys.flags structseq. It exposes the status of
8020 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008021
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Objects/structseq.c: Implemented new structseq representation. The
8023 patch makes structseqs (e.g. the return value of os.stat) more
8024 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008025
Georg Brandl3ee81df2008-05-17 18:14:43 +00008026- Patch #1700288: added a type attribute cache that caches method
8027 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008028
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008029- Bug #1776: __import__() no longer accepts filenames on any platform.

8035 envvar and sys.dont_write_bytecode attribute. All these can be set
8036 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008037
Georg Brandl3ee81df2008-05-17 18:14:43 +00008038- Improve some exception messages when Windows fails to load an
8039 extension module. Now we get for example '%1 is not a valid Win32
8040 application' instead of 'error code 193'.

8097
Georg Brandl21e99f42010-03-07 15:23:59 +00008098- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8100 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008101
Georg Brandl3ee81df2008-05-17 18:14:43 +00008102- Issue #1686386: Tuple's tp_repr did not take into account the
8103 possibility of having a self-referential tuple, which is possible
8104 from C code. Nor did object's tp_str consider that a type's tp_str
8105 could do something that could lead to an inifinite recursion.
8106 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8107 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008108
Georg Brandl3ee81df2008-05-17 18:14:43 +00008109- Issue #1164: It was possible to trigger deadlock when using the
8110 'print' statement to write to a file since the GIL was not released
8111 as needed. Now PyObject_Print() does the right thing along with
8112 various tp_print implementations of the built-in types and those in
8113 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008114
Georg Brandl3ee81df2008-05-17 18:14:43 +00008115- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00008122- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008123 PyObject_Call() never calling back out to Python code to trigger
8124 recursion depth updates/checks. Required the creation of a static
8125 RuntimeError instance in case normalizing an exception put the
8126 recursion check value past its limit. Fixes crashers

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008166- Request #1193128: str.translate() now allows a None argument for
8167 translations that only remove characters without re-mapping the
8168 remaining characters.
8169
Georg Brandl5cb76c12007-03-21 09:00:39 +00008170- Patch #1682205: a TypeError while unpacking an iterable is no longer
8171 masked by a generic one with the message "unpack non-sequence".

8174
Guido van Rossum143b5642007-03-23 04:58:42 +00008175- Bug #1683368: The object.__init__() and object.__new__() methods are
8176 now stricter in rejecting excess arguments. The only time when
8177 either allows excess arguments is when it is not overridden and the
8178 other one is. For backwards compatibility, when both are
8179 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008180 warning later). Also, type.__init__() insists on the same signature
8181 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008183- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8184 object to complex using its __complex__() method before falling back
8185 to the __float__() method. Therefore, the functions in the cmath
8186 module now can operate on objects that define a __complex__()
8187 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008205- Bug #1678647: write a newline after printing an exception in any
8206 case, even when converting the value to a string failed.
8207
Georg Brandl871f1bc2007-03-12 13:17:36 +00008208- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008209 its argument, if it exists. If not, it will work like before. This
8210 allows customizing the output of dir() in the presence of a
8211 __getattr__().

8221 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008222
Georg Brandlaa2321b2007-03-07 00:40:28 +00008223- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008224 makes the filenames the warning module prints much more sensible
8225 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008226

Georg Brandl0fca97a2007-03-05 22:28:08 +00008238- Patch #1674228: when assigning a slice (old-style), check for the
8239 sq_ass_slice instead of the sq_slice slot.
8240
Georg Brandl3ee81df2008-05-17 18:14:43 +00008241- When printing an unraisable error, don't print exceptions. before
8242 the name. This duplicates the behavior whening normally printing
8243 exceptions.

Neal Norwitzcbeb6872006-10-14 21:33:38 +00008292
Georg Brandl2c1375c2006-10-12 11:27:59 +00008293- Bug #1545497: when given an explicit base, int() did ignore NULs
8294 embedded in the string to convert.
8295
Georg Brandl846f73a2006-10-08 07:11:54 +00008296- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008326- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
8327 Also make sure that every exception class has __module__ set to
8328 'exceptions'.

Neal Norwitzdac090d2006-09-05 03:53:08 +00008343- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008344 generator expressions (x for x, in ... ) works again. Fixing this
8345 problem required changing the .pyc magic number. This means that
8346 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00008384- Removed uses of dict.has_key() from distutils, and uses of
8385 callable() from copy_reg.py, so the interpreter now starts up
8386 without warnings when '-3' is given. More work like this needs to

Georg Brandl3ee81df2008-05-17 18:14:43 +00009142- The implementation of UnicodeError objects has been simplified
9143 (start and end attributes are now stored directly as Py_ssize_t
9144 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009146- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9147 with RFC 3207 and forgets any knowledge obtained from the server not
9148 obtained from the TLS negotiation itself. Patch contributed by Bill
9149 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009150
Georg Brandl3ee81df2008-05-17 18:14:43 +00009151- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009152 that the SMTP.starttls() caller no longer needs to call ehlo()
9153 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009154 does not claim to support starttls. Adds the
9155 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9156 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009198- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009199 works as expected. ``mmap.find`` also takes an optional ``end``
9200 parameter.

9225 contents before adding elements from the iterable. This fix brings
9226 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009227
Georg Brandl3ee81df2008-05-17 18:14:43 +00009228- Added wide char functions to msvcrt module: getwch, getwche, putwch

9234
Georg Brandl3ee81df2008-05-17 18:14:43 +00009235- Marshal.dumps() now expects exact type matches for int, long, float,
9236 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9237 silently miscode subclasses of those types. Now, it raises a
9238 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009239

Georg Brandl3ee81df2008-05-17 18:14:43 +00009254 time so that opening a database previously created with the DB_DUP
9255 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9256 opens. Specifically: dictionary assignment to a DB object will
9257 replace all values for a given key when the database allows
9258 duplicate values. DB users should use DB.put(k, v) when they want
9259 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009260

9266 characters with ASCII value less than 32. Also, it correctly quotes
9267 dots only if they occur on a single line, as opposed to the previous
9268 behavior of quoting dots if they are the second character of any
9269 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009270

9299 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00009300

Georg Brandl3ee81df2008-05-17 18:14:43 +00009678- Removed the macfs module. It had been deprecated since Python 2.5.
9679 This lead to the deprecation of macostools.touched() as it relied
9680 solely on macfs and was a no-op under OS X.
