30 filename and date, conforming to the 'standards' they were originally
31 designed to follow. This improves compatibility with patch tools.
32
R. David Murray27ef9372010-04-12 14:26:06 +000033- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
34 character sets will now consistently use a Content-Transfer-Encoding of

50
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000051- Issue #7301: Add environment variable $PYTHONWARNINGS.
52
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000053- Issue #8329: Don't return the same lists from select.select when no fds are
54 changed.
55
Mark Dickinson82791672010-04-06 16:47:55 +000056- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
57 on 64-bit machines. The shift count for either left or right shift is
58 permitted to be up to sys.maxsize.
59
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000060- Ensure that tokenization of identifiers is not affected by locale.

65
Eric Smithd44b2fc2010-04-02 12:30:56 +000066- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
67 is called with a non-empty format string. This is an effort to
68 future-proof user code. If a derived class does not currently
69 implement __format__ but later adds its own __format__, it would
70 most likely break user code that had supplied a format string. This
71 will be changed to a DeprecationWaring in Python 3.3 and it will be
72 an error in Python 3.4.
73
Antoine Pitroua57df2c2010-03-31 21:32:15 +000074- Issue #8268: Old-style classes (not just instances) now support weak
75 references.

Victor Stinner66644262010-03-10 22:30:19 +000087- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000088 (SIGINT). If an error occurs while importing the site module, the error is
89 printed and Python exits. Initialize the GIL before importing the site

100 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
101 and `ssl.OPENSSL_VERSION_NUMBER`.
102
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000103- Issue #8310: Allow dis to examine new style classes.
104
Mark Dickinson8a950712010-04-03 15:47:46 +0000105- Issue #8257: The Decimal construct now accepts a float instance
106 directly, converting that float to a Decimal of equal value:
107
108 >>> Decimal(1.1)
109 Decimal('1.100000000000000088817841970012523233890533447265625')
110
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000111- collections.Counter() now supports a subtract() method.
112
Raymond Hettingera551f312010-04-04 18:34:45 +0000113- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000114 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000115
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000116- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000117 old-style comparison functions to new-style key-functions.
118
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000119- Issue #8294: The Fraction constructor now accepts Decimal and float
120 instances directly.
121
Mark Dickinsone096e822010-04-02 10:17:07 +0000122- Issue #7279: Comparisons involving a Decimal signaling NaN now
123 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000124 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
125 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000126
Mark Dickinson99d80962010-04-02 08:53:22 +0000127- Issue #2531: Comparison operations between floats and Decimal
128 instances now return a result based on the numeric values of the
129 operands; previously they returned an arbitrary result based on
130 the relative ordering of id(float) and id(Decimal).
131
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000132- Issue #8233: When run as a script, py_compile.py optionally takes a single
133 argument `-` which tells it to read files to compile from stdin. Each line
134 is read on demand and the named file is compiled immediately. (Original
135 patch by Piotr Ożarowski).
136
137- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
138 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000139
Florent Xicluna58b65662010-03-30 16:29:03 +0000140- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
141 form feed (0x0C) are now considered linebreaks, as specified in Unicode
142 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000143 http://www.unicode.org/reports/tr14/
144
Mark Dickinson9588d992010-03-27 11:14:37 +0000145- Comparisons using one of <, <=, >, >= between a complex instance and
146 a Fractions instance now raise TypeError instead of returning
147 True/False. This makes Fraction <=> complex comparisons consistent with
148 int <=> complex, float <=> complex, and complex <=> complex comparisons.
149
Michael Foorde6410c52010-03-29 20:04:23 +0000150- Addition of ``WeakSet`` to the ``weakref`` module.

161 now silenced.
162
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000163- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

170 method to LoggerAdapter.
171
Vinay Sajip31e928e2010-03-22 13:02:28 +0000172- Issue #8201: logging: Handle situation of non-ASCII and Unicode
173 logger names existing at the same time, causing a Unicode error
174 when configuration code attempted to sort the existing loggers.
175
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000176- Issue #8200: logging: Handle errors when multiprocessing is not

198
Georg Brandlba83f822010-03-14 09:50:54 +0000199- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000200 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000201 program name.

Georg Brandlba83f822010-03-14 09:50:54 +0000204 for ``TimedRotatingFileHandler`` by using the modification time of an
205 existing log file to compute the next rollover time. If the log file does
206 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000207
Georg Brandlba83f822010-03-14 09:50:54 +0000208- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

215
Georg Brandlba83f822010-03-14 09:50:54 +0000216- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
217 a base64 transfer-encoded payload *after* decoding it; it no longer does.
218 This is a behavior change, so email's minor version number is now bumped, to
219 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000220

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000245- Issue #8300: When passing a non-integer argument to struct.pack with any
246 integer format code, struct.pack first attempts to convert the non-integer
247 using its __index__ method. If that method is non-existent or raises
248 TypeError it goes on to try the __int__ method, as described below.
249
Georg Brandlba83f822010-03-14 09:50:54 +0000250- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
251 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
252 argument's __int__ method to convert to an integer before packing. It also
253 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
254 was inconsistent: __int__ was used for some integer codes but not for others,
255 and the set of integer codes for which it was used differed between native
256 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000554 file position when calling `truncate()`. It would previously change the file
555 position to the given argument, which goes against the tradition of

652Core and Builtins
653-----------------
654
Georg Brandlba83f822010-03-14 09:50:54 +0000655- The ``__complex__()`` method is now looked up on the class of instances to
656 make it consistent with other special methods.

660
Mark Dickinson1b34d252010-01-01 17:27:30 +0000661- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000662 DeprecationWarning when passed a float argument where an integer was expected.
663 These functions and methods now raise TypeError instead. The majority of the
664 effects of this change are in the extension modules, but some core functions
665 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
666 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000679- Issue #1811: Improve accuracy and cross-platform consistency for true division
680 of integers: the result of a/b is now correctly rounded for ints a and b (at
681 least on IEEE 754 platforms), and in particular does not depend on the
682 internal representation of a long.

690
Georg Brandlba83f822010-03-14 09:50:54 +0000691 These executables now work properly with the arch(1) command: ``arch -ppc
692 python`` will start a universal binary version of python in PPC mode (unlike
693 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000778- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
779 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
780 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
781 float arguments for integer format codes (other than 'L'): previously an
782 attempt to pass a float resulted in a DeprecationWarning; now it gives a
783 TypeError. For the 'L' format code (which previously had no warning) there is
784 now a DeprecationWarning.

833 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000834
Georg Brandlba83f822010-03-14 09:50:54 +0000835- Remove switch from "%f" formatting to "%g" formatting for floats larger than
836 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000837
Georg Brandlba83f822010-03-14 09:50:54 +0000838- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
839 1e-100 used to raise OverflowError, but now gives the requested 120
840 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000848
Georg Brandlba83f822010-03-14 09:50:54 +0000849- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
850 decimal string that's guaranteed to round back to x under correct rounding
851 (with round-half-to-even rounding mode). Previously it gave a string based on
852 rounding x to 17 decimal digits. repr(x) for a complex number behaves
853 similarly. On platforms where the correctly-rounded strtod and dtoa code is
854 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000855
Georg Brandlba83f822010-03-14 09:50:54 +0000856- Issue #7117: On almost all platforms: float-to-string and string-to-float
857 conversions within Python are now correctly rounded. Places these conversions
858 occur include: str for floats and complex numbers; the float and complex
859 constructors; old-style and new-style numeric formatting; serialization and
860 deserialization of floats and complex numbers using marshal, pickle and json;
861 parsing of float and imaginary literals in Python code; Decimal-to-float
862 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000863
Georg Brandlba83f822010-03-14 09:50:54 +0000864 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
865 providing correctly-rounded strtod and dtoa C functions. This code is
866 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
867 the C compiler. There may be a small number of platforms on which correct
868 operation of this code cannot be guaranteed, so the code is not used: notably,
869 this applies to platforms where the C double format is not IEEE 754 binary64,
870 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
871 and Python's configure script is unable to determine how to change the FPU
872 precision. On these platforms conversions use the platform strtod and dtoa,
873 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000874
Georg Brandlba83f822010-03-14 09:50:54 +0000875- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
876 uses the correctly-rounded string <-> float conversions described above (when
877 available), and so produces correctly rounded results that will display nicely
878 under the float repr. There are two related small changes: (1) round now
879 accepts any class with an ``__index__()`` method for its second argument (but
880 no longer accepts floats for the second argument), and (2) an excessively
881 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
882 raises an exception.

1017
Georg Brandlba83f822010-03-14 09:50:54 +00001018- ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001023- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00001024
Georg Brandlba83f822010-03-14 09:50:54 +00001025 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1026 (2) parsing of strings representing infinities and nans was locale aware; and
1027 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001028
Georg Brandlba83f822010-03-14 09:50:54 +00001029- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1030 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1031 but with at least one decimal point and with a default precision
1032 of 12. Previously, the behavior the same but with a default precision of 6.
1033 This more closely matches ``str()``, and reduces surprises when adding
1034 alignment flags to the empty presentation type. This also affects the new
1035 complex.__format__ in the same way.
1036
1037- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1038 classtype's, even if it was None. property now inserts the __doc__ into the
1039 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00001100 untrackable objects are not tracked by the garbage collector. This can reduce
1101 the size of collections and therefore the garbage collection overhead on

1109 internal representation of integers, for performance reasons. Base 2**30 is
1110 enabled by default on 64-bit machines. Add --enable-big-digits option to

1288 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002462 - If x is not an int, long or float, then packing x will always result in
2463 struct.error. Previously an x with an __int__ method could be packed by
2464 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2465 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2466 neither __int__ nor __long__, TypeError used to be raised (with a
2467 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2468 struct.error in other cases.

2471 argument with an __int__ method can be packed, but use of this feature
2472 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00002521 leak-chasing test runs give sensible results. The previous method of reaping
2522 threads could return successfully while some Thread objects were still
2523 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002524
Georg Brandlba83f822010-03-14 09:50:54 +00002525- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00002542 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Georg Brandl2bd92a52009-10-11 21:10:07 +00002643- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002644 AttributeError instead of RuntimeError, depending in which C API call
2645 exactly the recursion limit is exceeded. Consequently, both exception types
2646 are caught and silenced.

2662
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002663- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2664
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002665- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2666 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2667 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2668 ``printf`` function, whereas PyString_FromFormat has an independent
2669 implementation and uses "%zd" on all platforms for size_t values.
2670 This makes a difference on win64, where ``printf`` needs "%Id" to display
2671 64bit values.
2672
Benjamin Peterson97179b02008-09-09 20:55:01 +00002673- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2674 error.
2675
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002676- Issue #3777: long() applied to a float object now always return a long
2677 object; previously an int would be returned for small values. the __long__
2678 method is allowed to return either an int or a long, but the behaviour of
2679 float objects should not change to respect backward compatibility.
2680
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002681- Issue #3751: str.rpartition would perform a left-partition when called with
2682 a unicode argument.
2683
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002684- Issue #3683: Fix compilation when --without-threads is given.
2685
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002686- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002687 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002688 was correctly parsed but parsing of subsequent arguments failed.
2689
Vinay Sajip35e3b032008-09-01 14:33:59 +00002690- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002691 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2692 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2693 when given a tuple of classes as second argument, were looking up
2694 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2695 type object.
2696
Neal Norwitz18aa3882008-08-24 05:04:52 +00002697- Fix crashes on memory allocation failure found with failmalloc.
2698
2699- Fix memory leaks found with valgrind and update suppressions file.
2700
2701- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2702
2703- Fix problem using wrong name in decimal module reported by pychecker.
2704
Christian Heimes7d4c3172008-08-22 19:47:25 +00002705- Silenced another compiler warning about a used but not defined
2706 function 'stringlib_contains_obj'.
2707
Benjamin Peterson712ee922008-08-24 18:10:20 +00002708- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2709 ``__delslice__``.
2710
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002711- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2712 library targets in the Makefile.
2713
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002714- Issue #1204: The configure script now tests for additional libraries
2715 that may be required when linking against readline. This fixes issues
2716 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

2738
Nick Coghland2e09382008-09-11 12:11:06 +00002739- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002740 return a list or None rather than a custom object.
2741
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002742- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2766 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2767 for catch_warnings() also led to an improvement in the raising of a
2768 DeprecationWarning related to warnings.warn_explicit().
2769
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002770- The deprecation warnings for the old camelCase threading API were removed.

2839Core and Builtins
2840-----------------
2841
Guido van Rossumf8402962008-08-20 15:01:50 +00002842- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2843 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2844 extensions do not automatically benefit from the class attribute
2845 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2846 to their tp_flags field if they care. This is a backwards
2847 compatibility feature; in 3.0, all types will use the cache by
2848 default.
2849
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002850- Keyword arguments can now follow starred arguments. (``f(a, *args,
2851 keyword=23)`` is now valid syntax.)
2852
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002853- ctypes function pointers that are COM methods have a boolean True
2854 value again.
2855
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002856- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2857 by denying s# to parse objects that have a releasebuffer procedure,
2858 and introducing s*.
2859
Georg Brandl1e13ea92008-08-11 09:07:59 +00002860- Issue #3537: Fix an assertion failure when an empty but presized dict
2861 object was stored in the freelist.
2862
Mark Dickinsonb6467572008-08-04 21:30:09 +00002863- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2864 ValueError consistently across platforms.
2865
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002866- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2867 (64bit Unix, for example), unichr() would truncate its argument and return
2868 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2869
Neal Norwitze7d8be82008-07-31 17:17:14 +00002870- Apply security patches from Apple.
2871
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002872- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2873 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2874
Antoine Pitrou92f82162008-07-25 22:22:08 +00002875- Issue #1819: function calls with several named parameters are now on
2876 average 35% faster (as measured by pybench).
2877
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002878- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2879 the python debugger steps into a class statement: the free variables (local
2880 variables defined in an outer scope) would be deleted from the outer scope.
2881
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002882- Issue #2620: Overflow checking when allocating or reallocating memory
2883 was not always being done properly in some python types and extension
2884 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2885 all been updated to perform better checks and places in the code that
2886 would previously leak memory on the error path when such an allocation
2887 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002892- Issue #3612: Added some missing basic types in ctypes.wintypes.
2893
Benjamin Petersone977ad42008-08-20 01:42:01 +00002894- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2895 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2896
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002897- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2898 version reported by these tools does not necessarily follow the python
2899 version numbering scheme, so the module is less strict when parsing it.
2900
Nick Coghlanf70385a2008-08-18 12:42:46 +00002901- Issue #2235: Added Py3k warnings for types which will become unhashable
2902 under the stricter __hash__ inheritance rules in 3.0. Several types
2903 which did not meet the rules for hash invariants and were already
2904 unhashable in 3.0 have now been explicitly flagged as unhashable in
2905 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2906 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2907
Brett Cannon88f801d2008-08-18 00:46:22 +00002908- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2909 imported into the module but exposed as part of the module's API.
2910
Brett Cannon7b96f072008-08-18 00:41:11 +00002911- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002915- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2916
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002917- Issue #3575: Incremental decoder's decode function now takes bytearray
2918 by using 's*' instead of 't#'.
2919
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002920- Issue #2222: Fixed reference leak when occurred os.rename()

Antoine Pitroude781a42008-08-09 12:43:23 +00002977 asking for a specific length. This problem only affected files opened

3021
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003022- Issue #643841: The language reference now provides more detailed

3034-----------------
3035
Georg Brandl3e483f62008-07-16 22:57:41 +00003036- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3037 its methods now allow for items objects that can be converted to
3038 an integer using operator.index().
3039
Mark Dickinson64b7e502008-07-16 09:40:03 +00003040- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3041 produced a ValueError instead of giving the correct float.
3042
Eric Smitha5fa5a22008-07-16 00:11:49 +00003043- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3044 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3045
Mark Dickinson7103aa42008-07-15 19:08:33 +00003046- Issue #3008: the float type has a new instance method 'float.hex'
3047 and a new class method 'float.fromhex' to convert floating-point
3048 numbers to and from hexadecimal strings, respectively.
3049
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003050- Issue #2235: __hash__ is once again inherited by default. To allow
3051 collections.Hashable to remain meaningful in the presence of the
3052 default hash implementation (object.__hash__), it is now possible
3053 to explicit block inheritance of hash by setting __hash__=None at
3054 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3055 level.
3056
Nick Coghlanb028f502008-07-13 14:52:36 +00003057- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3058 the parent module cannot be found while performing an absolute import.
3059 This means that an incorrectly defined __package__ attribute will
3060 now only prevent relative imports in that module rather than causing
3061 all imports from that module to fail.
3062
Nick Coghlan14ff9942008-07-08 14:21:42 +00003063- Issue #2517: Allow unicode messages in Exceptions again by correctly

3073 another thread's dictionary.
3074
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003075- Issue #3004: Minor change to slice.indices(): the start and stop
3076 arguments are now treated identically, making the behaviour easier
3077 to describe and understand. For example, slice(None, -10,
3078 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3079 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3080 10, -1).
3081
Georg Brandl278fc502008-07-19 12:46:12 +00003082- Issue #3219: Calling a function with repeated keyword arguments,
3083 f(a=2, a=23), would not cause a syntax error. This was a regression
3084 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003122- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3123 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003124 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003125 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003141- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3531
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003532- On MacOS X it is now possible to install the framework in 64-bit
3533 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003534 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003535
3536 This is controlled by the configure argument ``--with-universal-archs``:
3537
3538 - ``--with-universal-archs=all``: install 4-way universal
3539
3540 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3541
3542 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3543
3544 This option should be used in combination with ``--enable-universalsdk=``.
3545
3546 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 +00003596- Issue #1631171: Re-implement the 'warnings' module in C (the
3597 original Python code has been kept as backup). This will allow for
3598 using the 'warning's machinery in such places as the parser where
3599 use of pure Python code is not possible. Both the ``showarning()``
3600 and ``formatwarning()`` gain an optional 'line' argument which is
3601 not called by default for backwards-compatibility reasons. Setting
3602 ``warnings.showwarning()`` to an implementation that lacks support
3603 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003666- Issue #2550: The approach used by client/server code for obtaining
3667 ports to listen on in network-oriented tests has been refined in an
3668 effort to facilitate running multiple instances of the entire
3669 regression test suite in parallel without issue.
3670 test_support.bind_port() has been fixed such that it will always
3671 return a unique port -- which wasn't always the case with the
3672 previous implementation, especially if socket options had been set
3673 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3674 new implementation of bind_port() will actually raise an exception
3675 if it is passed an AF_INET/SOCK_STREAM socket with either the
3676 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3677 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3678 the socket it's been passed. This currently only applies to
3679 Windows. This option prevents any other sockets from binding to the
3680 host/port we've bound to, thus removing the possibility of the
3681 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3682 when a second SOCK_STREAM socket binds and accepts to a host/port
3683 that's already been bound by another socket. The optional preferred
3684 port parameter to bind_port() has been removed. Under no
3685 circumstances should tests be hard coding ports!
3686
3687 test_support.find_unused_port() has also been introduced, which will
3688 pass a temporary socket object to bind_port() in order to obtain an
3689 unused port. The temporary socket object is then closed and
3690 deleted, and the port is returned. This method should only be used
3691 for obtaining an unused port in order to pass to an external program
3692 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3693 a parameter to a server-oriented class that doesn't give you direct
3694 access to the underlying socket used.
3695
3696 Finally, test_support.HOST has been introduced, which should be used
3697 for the host argument of any relevant socket calls (i.e. bind and
3698 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003699
3700 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003701 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003702 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3703 test_asynchat and test_socket_ssl.
3704
Georg Brandl3ee81df2008-05-17 18:14:43 +00003705 It is now possible for multiple instances of the regression test
3706 suite to run in parallel without issue.

3973-----------------
3974
Fred Drakea8ee94b2008-03-01 02:45:07 +00003975- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003976 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003981
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003982- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003983 issue 215555 for a discussion.
3984
Eric Smitha73fbe72008-02-23 03:09:44 +00003985- Added the future_builtins module, which contains hex() and oct().
3986 These are the PEP 3127 version of these functions, designed to be
3987 compatible with the hex() and oct() builtins from Python 3.0. They
3988 differ slightly in their output formats from the existing, unchanged
3989 Python 2.6 builtins. The expected usage of the future_builtins
3990 module is:
3991 from future_builtins import hex, oct
3992
Eric Smith7ef40bf2008-02-20 23:34:22 +00003993- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3994 exponents for exponents with absolute value < 100. Follows C99
3995 standard. This is a change on Windows, which would use 3 digits.
3996 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3997 so that any alterations it does to the resulting string will be
3998 available in stringlib/formatter.h (for float.__format__).
3999
Eric Smith5a3c1352008-02-19 13:21:56 +00004000- Implemented PEP 3101, Advanced String Formatting. This adds a new
4001 builtin format(); a format() method for str and unicode; a
4002 __format__() method to object, str, unicode, int, long, float, and
4003 datetime; the class string.Formatter; and the C API
4004 PyObject_Format().
4005
Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Fixed several potential crashes, all caused by specially crafted
4007 __del__ methods exploiting objects in temporarily inconsistent
4008 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004009
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004010- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011 prevent a possible crash: an Abstract Base Class would try to access
4012 a slot on a registered virtual subclass.

4015 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004016
Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Clear all free lists during a gc.collect() of the highest generation
4018 in order to allow pymalloc to free more arenas. Python may give back
4019 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004020
Georg Brandl3ee81df2008-05-17 18:14:43 +00004021- Issue #2045: Fix an infinite recursion triggered when printing a
4022 subclass of collections.defaultdict, if its default_factory is set
4023 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004024
Christian Heimesf75dbef2008-02-08 00:11:31 +00004025- Fixed a minor memory leak in dictobject.c. The content of the free
4026 list was not freed on interpreter shutdown.
4027
Georg Brandl21e99f42010-03-07 15:23:59 +00004028- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4032 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004033 to compact the internal free lists of pre-allocted ints and floats.
4034
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4036 calls. Python expected the return type int but the fork familie
4037 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004038
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4040 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004041
Georg Brandl3ee81df2008-05-17 18:14:43 +00004042- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4043 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004044
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4046 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004048- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4049 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004050
Georg Brandl3ee81df2008-05-17 18:14:43 +00004051- Patch #1473257: generator objects gain a gi_code attribute. This is
4052 the same object as the func_code attribute of the function that
4053 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004054
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055- Issue #1920: "while 0" statements were completely removed by the
4056 compiler, even in the presence of an "else" clause, which is
4057 supposed to be run when the condition is false. Now the compiler
4058 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004059
Guido van Rossumeead05f2008-01-24 18:21:02 +00004060- A few crashers fixed: weakref_in_del.py (issue #1377858);
4061 loosing_dict_ref.py (issue #1303614, test67.py);
4062 borrowed_ref_[34].py (not in tracker).
4063
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004064- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004065 suppressed while an extension is loaded by calling SetErrorMode in
4066 dynload_win.c. The error is still reported properly.
4067
Georg Brandl3ee81df2008-05-17 18:14:43 +00004068- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004069 several extension methods and modules do not work without unicode
4070 support.
4071
Georg Brandl26543b12008-01-21 18:36:51 +00004072- Issue #1882: when compiling code from a string, encoding cookies in the
4073 second line of code were not always recognized correctly.
4074
Georg Brandl14404b62008-01-19 19:27:05 +00004075- Issue #1679: "0x" was taken as a valid integer literal.
4076
Georg Brandl6caad7d2008-01-26 14:19:22 +00004077- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004078 added.
4079
Christian Heimesc94e2b52008-01-14 04:13:37 +00004080- sys.float_info / PyFloat_GetInfo: The floating point information
4081 object was converted from a dict to a specialized structseq object.
4082
Georg Brandl3ee81df2008-05-17 18:14:43 +00004083- Patch #1816: Added sys.flags structseq. It exposes the status of
4084 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004085
Georg Brandl3ee81df2008-05-17 18:14:43 +00004086- Objects/structseq.c: Implemented new structseq representation. The
4087 patch makes structseqs (e.g. the return value of os.stat) more
4088 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004089
Georg Brandl3ee81df2008-05-17 18:14:43 +00004090- Patch #1700288: added a type attribute cache that caches method
4091 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004092
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004093- Bug #1776: __import__() no longer accepts filenames on any platform.
4094 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004095
Georg Brandlaed6c662008-01-07 17:25:53 +00004096- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4097
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4099 envvar and sys.dont_write_bytecode attribute. All these can be set
4100 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Improve some exception messages when Windows fails to load an
4103 extension module. Now we get for example '%1 is not a valid Win32
4104 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Bug #1481296: Fixed long(float('nan')) != 0L.

4109 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004110
Christian Heimes0a8143f2007-12-18 23:22:54 +00004111- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112 and INF. float("nan"), float("inf") and float("-inf") now work on
4113 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004114
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115- Compiler now generates simpler and faster code for dictionary
4116 literals. The oparg for BUILD_MAP now indicates an estimated
4117 dictionary size. There is a new opcode, STORE_MAP, for adding
4118 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004119
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004128- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004129 SystemError.
4130
Nick Coghlanef01d822007-12-03 12:55:17 +00004131- PEP 366: Allow explicit relative imports when executing modules
4132 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00004147- Patch #1739468: Directories and zipfiles containing a __main__.py
4148 file can now be directly executed by passing their name to the
4149 interpreter. The directory/zipfile is automatically inserted as the
4150 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Issue #1265: Fix a problem with sys.settrace, if the tracing
4153 function uses a generator expression when at the same time the
4154 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004155
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004156- sets and frozensets now have an isdisjoint() method.
4157
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004158- optimize the performance of builtin.sum().
4159
Neal Norwitz44f326e2007-10-05 05:29:17 +00004160- Fix warnings found by the new version of the Coverity checker.
4161
Georg Brandl21e99f42010-03-07 15:23:59 +00004162- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4164 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Issue #1686386: Tuple's tp_repr did not take into account the
4167 possibility of having a self-referential tuple, which is possible
4168 from C code. Nor did object's tp_str consider that a type's tp_str
4169 could do something that could lead to an inifinite recursion.
4170 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4171 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004172
Georg Brandl3ee81df2008-05-17 18:14:43 +00004173- Issue #1164: It was possible to trigger deadlock when using the
4174 'print' statement to write to a file since the GIL was not released
4175 as needed. Now PyObject_Print() does the right thing along with
4176 various tp_print implementations of the built-in types and those in
4177 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004178
Georg Brandl3ee81df2008-05-17 18:14:43 +00004179- Issue #1147: Exceptions were directly allowing string exceptions in
4180 their throw() method even though string exceptions no longer
4181 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004182
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- Issue #1096: Prevent a segfault from getting the repr of a very
4184 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004185
Brett Cannon1e534b52007-09-07 04:18:30 +00004186- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187 PyObject_Call() never calling back out to Python code to trigger
4188 recursion depth updates/checks. Required the creation of a static
4189 RuntimeError instance in case normalizing an exception put the
4190 recursion check value past its limit. Fixes crashers
4191 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004206- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207 __*__ attributes. (Some already existed, e.g., __doc__ and
4208 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004209
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004210- Add -3 option to the interpreter to warn about features that are
4211 deprecated and will be changed/removed in Python 3.0.
4212
Georg Brandl2134e752007-05-21 20:34:16 +00004213- Patch #1686487: you can now pass any mapping after '**' in function
4214 calls.
4215
Collin Winter62903052007-05-18 23:11:24 +00004216- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217 "except E as target:". This is to provide forwards compatibility
4218 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004219
Brett Cannon229cee22007-05-05 01:34:02 +00004220- Deprecate BaseException.message as per PEP 352.
4221
Georg Brandl3ee81df2008-05-17 18:14:43 +00004222- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004223 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004224
Vinay Sajip8549ce32007-05-06 17:53:37 +00004225- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004226 setting a plain string, ie don't expand to single letter identifiers.
4227
Raymond Hettinger13936692007-04-11 18:40:58 +00004228- Request #1191699: Slices can now be pickled.
4229
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004230- Request #1193128: str.translate() now allows a None argument for
4231 translations that only remove characters without re-mapping the
4232 remaining characters.
4233
Georg Brandl5cb76c12007-03-21 09:00:39 +00004234- Patch #1682205: a TypeError while unpacking an iterable is no longer
4235 masked by a generic one with the message "unpack non-sequence".
4236
Neal Norwitzaa754b72007-03-21 06:39:48 +00004237- Remove unused file Python/fmod.c.
4238
Guido van Rossum143b5642007-03-23 04:58:42 +00004239- Bug #1683368: The object.__init__() and object.__new__() methods are
4240 now stricter in rejecting excess arguments. The only time when
4241 either allows excess arguments is when it is not overridden and the
4242 other one is. For backwards compatibility, when both are
4243 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004244 warning later). Also, type.__init__() insists on the same signature
4245 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004246
Georg Brandl3ee81df2008-05-17 18:14:43 +00004247- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4248 object to complex using its __complex__() method before falling back
4249 to the __float__() method. Therefore, the functions in the cmath
4250 module now can operate on objects that define a __complex__()

Georg Brandl2c1375c2006-10-12 11:27:59 +00004357- Bug #1545497: when given an explicit base, int() did ignore NULs
4358 embedded in the string to convert.
4359
Georg Brandl846f73a2006-10-08 07:11:54 +00004360- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004408 generator expressions (x for x, in ... ) works again. Fixing this
4409 problem required changing the .pyc magic number. This means that

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005223 that the SMTP.starttls() caller no longer needs to call ehlo()
5224 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225 does not claim to support starttls. Adds the
5226 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5227 Fenner.

5307 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5308 silently miscode subclasses of those types. Now, it raises a
5309 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005310

Georg Brandl3ee81df2008-05-17 18:14:43 +00005325 time so that opening a database previously created with the DB_DUP
5326 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5327 opens. Specifically: dictionary assignment to a DB object will
5328 replace all values for a given key when the database allows
5329 duplicate values. DB users should use DB.put(k, v) when they want
5330 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005331

5337 characters with ASCII value less than 32. Also, it correctly quotes
5338 dots only if they occur on a single line, as opposed to the previous
5339 behavior of quoting dots if they are the second character of any
5340 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005341
