433 This prevents user-created self-referencing ordered dictionaries from
434 becoming permanently uncollectable GC garbage. The downside is that

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001281- Issue #7301: Add environment variable $PYTHONWARNINGS.
1282
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001283- Issue #8329: Don't return the same lists from select.select when no fds are
1284 changed.
1285
Georg Brandlfee0f442010-05-22 21:26:21 +00001286- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001287 on 64-bit machines. The shift count for either left or right shift is
1288 permitted to be up to sys.maxsize.

1295
Georg Brandlfee0f442010-05-22 21:26:21 +00001296- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1297 with a non-empty format string. This is an effort to future-proof user
1298 code. If a derived class does not currently implement __format__ but later
1299 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001300 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001301 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001334- Issue #8257: The Decimal construct now accepts a float instance directly,
1335 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001336

Georg Brandlfee0f442010-05-22 21:26:21 +00001351- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1352 InvalidOperation instead of returning False. (Comparisons involving a quiet
1353 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1354 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001355
Georg Brandlfee0f442010-05-22 21:26:21 +00001356- Issue #2531: Comparison operations between floats and Decimal instances now
1357 return a result based on the numeric values of the operands; previously they
1358 returned an arbitrary result based on the relative ordering of id(float) and
1359 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001361- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001362 argument `-` which tells it to read files to compile from stdin. Each line is
1363 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001373- Comparisons using one of <, <=, >, >= between a complex instance and a
1374 Fractions instance now raise TypeError instead of returning True/False. This
1375 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1376 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001733- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1734 and add the additional members returned in an OSVERSIONINFOEX structure. The
1735 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001738- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1739 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1740 returning NULL. The macro now returns a statically allocated empty string
1741 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00001786- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001787 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001788 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001793- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001794 file position when calling `truncate()`. It would previously change the file
1795 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001796 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1797
Georg Brandlba83f822010-03-14 09:50:54 +00001798- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1799 class used to represent files stored inside an archive. The new
1800 implementation is significantly faster and can be wrapped in a
1801 ``io.BufferedReader`` object for more speedups. It also solves an issue
1802 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001813- Issue #7748: Since unicode values are supported for some metadata options in
1814 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1815 encoded string for them. This ensures that the upload and register commands
1816 send the correct values to PyPI without any error.

1891-----------------
1892
Georg Brandlba83f822010-03-14 09:50:54 +00001893- The ``__complex__()`` method is now looked up on the class of instances to
1894 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001895
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001896- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1897 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1898
Mark Dickinson1b34d252010-01-01 17:27:30 +00001899- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001900 DeprecationWarning when passed a float argument where an integer was expected.
1901 These functions and methods now raise TypeError instead. The majority of the
1902 effects of this change are in the extension modules, but some core functions
1903 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1904 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001905

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001914- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1915 used to drop the time part of the result.
1916
Georg Brandlba83f822010-03-14 09:50:54 +00001917- Issue #1811: Improve accuracy and cross-platform consistency for true division
1918 of integers: the result of a/b is now correctly rounded for ints a and b (at
1919 least on IEEE 754 platforms), and in particular does not depend on the
1920 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001921
Georg Brandlba83f822010-03-14 09:50:54 +00001922- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1923 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1924 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001925

Ronald Oussoren92919a62009-12-24 13:30:58 +00001927 executables on OSX.
1928
Georg Brandlba83f822010-03-14 09:50:54 +00001929 These executables now work properly with the arch(1) command: ``arch -ppc
1930 python`` will start a universal binary version of python in PPC mode (unlike
1931 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001932
Georg Brandlba83f822010-03-14 09:50:54 +00001933- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

1946 allowing for a maximum number of tasks within the pool to be completed by the
1947 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00001953- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001954 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1955 alternative to cPickle if you care about performance. Patch by Florent

Benjamin Petersonddd392c2009-12-13 19:19:07 +00001990- Issue #7349: Make methods of file objects in the io module accept None as an
1991 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1992 the same as passing no argument.
1993
Georg Brandlba83f822010-03-14 09:50:54 +00001994- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00002016- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2017 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2018 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

2071 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002072

Georg Brandlba83f822010-03-14 09:50:54 +00002087- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2088 decimal string that's guaranteed to round back to x under correct rounding
2089 (with round-half-to-even rounding mode). Previously it gave a string based on
2090 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2091 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2092 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002093
Georg Brandlba83f822010-03-14 09:50:54 +00002094- Issue #7117: On almost all platforms: float-to-string and string-to-float
2095 conversions within Python are now correctly rounded. Places these conversions
2096 occur include: str for floats and complex numbers; the float and complex
2097 constructors; old-style and new-style numeric formatting; serialization and
2098 deserialization of floats and complex numbers using marshal, pickle and json;
2099 parsing of float and imaginary literals in Python code; Decimal-to-float
2100 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002101
Georg Brandlba83f822010-03-14 09:50:54 +00002102 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2103 providing correctly-rounded strtod and dtoa C functions. This code is
2104 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2105 the C compiler. There may be a small number of platforms on which correct
2106 operation of this code cannot be guaranteed, so the code is not used: notably,
2107 this applies to platforms where the C double format is not IEEE 754 binary64,
2108 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2109 and Python's configure script is unable to determine how to change the FPU
2110 precision. On these platforms conversions use the platform strtod and dtoa,
2111 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002112
Georg Brandlba83f822010-03-14 09:50:54 +00002113- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2114 uses the correctly-rounded string <-> float conversions described above (when
2115 available), and so produces correctly rounded results that will display nicely
2116 under the float repr. There are two related small changes: (1) round now
2117 accepts any class with an ``__index__()`` method for its second argument (but
2118 no longer accepts floats for the second argument), and (2) an excessively
2119 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2120 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002338 untrackable objects are not tracked by the garbage collector. This can reduce
2339 the size of collections and therefore the garbage collection overhead on
2340 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00002346- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2347 internal representation of integers, for performance reasons. Base 2**30 is
2348 enabled by default on 64-bit machines. Add --enable-big-digits option to
2349 configure, which overrides the default. Add sys.long_info structseq to
2350 provide information about the internal format.

2381
Georg Brandl29c6a282009-04-05 20:23:13 +00002382- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002383 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00002413- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2414 existing .py counterpart, override the co_filename attributes of all code
2415 objects if the original filename is obsolete (which can happen if the file has

2470
Georg Brandlba83f822010-03-14 09:50:54 +00002471- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2472 file objects with closefd=False. The file descriptor is still kept open but
2473 the file object behaves like a closed file. The ``FileIO`` object also got a
2474 new readonly attribute ``closefd``.

2493
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002494- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002497- On windows, ``os.chdir()`` given unicode was not working if
2498 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2499 this code path is really executed because I cannot move to such directory on
2500 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002502- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2503 element is temporarily replaced with an equivalent frozenset. But the
2504 eventual KeyError would always report the empty ``frozenset()`` as the missing
2505 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002525- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2526 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2527 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2528 of using the replace error handler in PyUnicode_DecodeUTF8().
2529
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002530- Issue #3739: The unicode-internal encoder now reports the number of characters

3702 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3703 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3704 neither __int__ nor __long__, TypeError used to be raised (with a
3705 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3706 struct.error in other cases.

3709 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003903- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3905 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3906 ``printf`` function, whereas PyString_FromFormat has an independent
3907 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004004 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4005 for catch_warnings() also led to an improvement in the raising of a
4006 DeprecationWarning related to warnings.warn_explicit().
4007

4030
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004031- Issue #2975: When compiling several extension modules with Visual Studio 2008
4032 from the same python interpreter, some environment variables would grow
4033 without limit.
4034
Benjamin Peterson37346b22008-08-23 20:27:43 +00004035- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004072What's New in Python 2.6 beta 3?
4073================================
4074
Barry Warsaw07a4a382008-08-21 01:15:08 +00004075*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004076
4077Core and Builtins
4078-----------------
4079
Guido van Rossumf8402962008-08-20 15:01:50 +00004080- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4081 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4082 extensions do not automatically benefit from the class attribute
4083 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4084 to their tp_flags field if they care. This is a backwards
4085 compatibility feature; in 3.0, all types will use the cache by
4086 default.
4087
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004088- Keyword arguments can now follow starred arguments. (``f(a, *args,
4089 keyword=23)`` is now valid syntax.)
4090
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004091- ctypes function pointers that are COM methods have a boolean True
4092 value again.
4093
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004094- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4095 by denying s# to parse objects that have a releasebuffer procedure,
4096 and introducing s*.
4097
Georg Brandl1e13ea92008-08-11 09:07:59 +00004098- Issue #3537: Fix an assertion failure when an empty but presized dict
4099 object was stored in the freelist.
4100
Mark Dickinsonb6467572008-08-04 21:30:09 +00004101- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4102 ValueError consistently across platforms.
4103
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004104- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4105 (64bit Unix, for example), unichr() would truncate its argument and return
4106 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4107
Neal Norwitze7d8be82008-07-31 17:17:14 +00004108- Apply security patches from Apple.
4109
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004110- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4111 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4112
Antoine Pitrou92f82162008-07-25 22:22:08 +00004113- Issue #1819: function calls with several named parameters are now on
4114 average 35% faster (as measured by pybench).
4115
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004116- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4117 the python debugger steps into a class statement: the free variables (local
4118 variables defined in an outer scope) would be deleted from the outer scope.
4119
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004120- Issue #2620: Overflow checking when allocating or reallocating memory
4121 was not always being done properly in some python types and extension
4122 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4123 all been updated to perform better checks and places in the code that
4124 would previously leak memory on the error path when such an allocation
4125 failed have been fixed.

4128-------
4129

4131
Benjamin Petersone977ad42008-08-20 01:42:01 +00004132- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4133 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4134
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004135- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4136 version reported by these tools does not necessarily follow the python
4137 version numbering scheme, so the module is less strict when parsing it.
4138
Nick Coghlanf70385a2008-08-18 12:42:46 +00004139- Issue #2235: Added Py3k warnings for types which will become unhashable
4140 under the stricter __hash__ inheritance rules in 3.0. Several types
4141 which did not meet the rules for hash invariants and were already
4142 unhashable in 3.0 have now been explicitly flagged as unhashable in
4143 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4144 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4145
Brett Cannon88f801d2008-08-18 00:46:22 +00004146- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4154
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004155- Issue #3575: Incremental decoder's decode function now takes bytearray
4156 by using 's*' instead of 't#'.
4157
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004158- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004159 fails unicode conversion on 2nd parameter. (windows only)
4160
Georg Brandl222e2082010-08-01 22:27:39 +00004161- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004162 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00004165 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004166
Facundo Batistaeb90b782008-08-16 14:44:07 +00004167- Issue #2776: fixed small issue when handling an URL with double slash
4168 after a 302 response in the case of not going through a proxy.
4169
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004170- Issue #2676: in the email package, content-type parsing was hanging on
4171 pathological input because of quadratic or exponential behaviour of a
4172 regular expression.
4173
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004174- Issue #3476: binary buffered reading through the new "io" library is now
4175 thread-safe.
4176
Brett Cannonbf3157b2008-08-14 05:00:03 +00004177- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4178 since mimetools itself is deprecated. Because modules are cached, all
4179 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4180
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004181- Issue #3134: shutil referenced undefined WindowsError symbol.
4182
Robert Schuppenies14646332008-08-10 11:01:53 +00004183- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4184 menu entries were not deleted.
4185
Brett Cannon83e81842008-08-09 23:30:55 +00004186- Copied the implementation of reduce() to _functools.reduce() to have a
4187 version that did not raise a DeprecationWarning under -3.
4188
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004189- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4190 a MemoryError rather than silently stop the iteration.
4191
Guido van Rossum59ce9012008-08-09 14:55:34 +00004192- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4193 to _sre.compile() will now be rejected. This should not affect anybody
4194 since the re.compile() function never generates invalid re-bytecode.
4195
Skip Montanaroa032bf42008-08-08 22:52:51 +00004196- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4197 upon first access it can be automatically initialized from the csv file if
4198 it wasn't initialized during instantiation.
4199
Brett Cannon3aa2a492008-08-06 22:28:09 +00004200- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4201 the reload() built-in has been removed.
4202
Brett Cannon7e30b672008-08-04 21:52:25 +00004203- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004204 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004215 asking for a specific length. This problem only affected files opened
4216 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004217

4262 regarding lack of coverage of new-style classes have also been
4263 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004266What's New in Python 2.6 beta 2?
4267================================
4268
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004269*Release date: 17-Jul-2008*
4270
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004271Core and Builtins
4272-----------------
4273
Georg Brandl3e483f62008-07-16 22:57:41 +00004274- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4275 its methods now allow for items objects that can be converted to
4276 an integer using operator.index().
4277
Mark Dickinson64b7e502008-07-16 09:40:03 +00004278- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4279 produced a ValueError instead of giving the correct float.
4280
Eric Smitha5fa5a22008-07-16 00:11:49 +00004281- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4282 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4283
Mark Dickinson7103aa42008-07-15 19:08:33 +00004284- Issue #3008: the float type has a new instance method 'float.hex'
4285 and a new class method 'float.fromhex' to convert floating-point
4286 numbers to and from hexadecimal strings, respectively.
4287
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004288- Issue #2235: __hash__ is once again inherited by default. To allow
4289 collections.Hashable to remain meaningful in the presence of the
4290 default hash implementation (object.__hash__), it is now possible
4291 to explicit block inheritance of hash by setting __hash__=None at
4292 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4293 level.
4294
Nick Coghlanb028f502008-07-13 14:52:36 +00004295- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4296 the parent module cannot be found while performing an absolute import.
4297 This means that an incorrectly defined __package__ attribute will
4298 now only prevent relative imports in that module rather than causing
4299 all imports from that module to fail.
4300
Nick Coghlan14ff9942008-07-08 14:21:42 +00004301- Issue #2517: Allow unicode messages in Exceptions again by correctly
4302 bypassing the instance dictionary when looking up __unicode__ on
4303 new-style classes.
4304
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004305- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4306 set to a custom object whose write() method happens to install
4307 another file in sys.stdout.
4308
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004309- Issue #3088: Corrected a race condition in classes derived from
4310 threading.local: the first member set by a thread could be saved in
4311 another thread's dictionary.
4312
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004313- Issue #3004: Minor change to slice.indices(): the start and stop
4314 arguments are now treated identically, making the behaviour easier
4315 to describe and understand. For example, slice(None, -10,
4316 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4317 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4318 10, -1).
4319
Georg Brandl278fc502008-07-19 12:46:12 +00004320- Issue #3219: Calling a function with repeated keyword arguments,
4321 f(a=2, a=23), would not cause a syntax error. This was a regression
4322 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004323
Georg Brandl278fc502008-07-19 12:46:12 +00004324- Issue #2862: Make int and float freelist management consistent with
4325 other freelists. Changes their CompactFreeList apis into
4326 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004327
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004328Library
4329-------
4330
Thomas Heller57adf222008-08-14 19:10:48 +00004331- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4332 api functions without holding the GIL, which could lead to a fatal
4333 error when they failed.
4334
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004335- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4336

4342
Jesse Noller13e9d582008-07-16 14:32:36 +00004343- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4344 ForkingPickler.register() to resolve conflict with ctypes.
4345
Vinay Sajip51e65192008-07-18 09:01:10 +00004346- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004347
Thomas Heller880f5292008-07-15 19:39:38 +00004348- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4349 a valid dlerror() message.
4350
Thomas Heller2bad6572008-07-15 17:19:50 +00004351- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4352 incomplete structure was created.
4353
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004354- Issue #3339: dummy_thread.acquire() should not return None.
4355
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004356- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4357
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004358- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004359
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004360- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4361 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004362 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004363 content-length. The problem had been corrected in the 2.4 branch, but never
4364 merged into trunk.
4365
Georg Brandle78fbcc2008-07-05 10:13:36 +00004366- Issue #2663: add filtering capability to shutil.copytree().
4367

4369
4370- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4371
4372- Issue #1746: Correct handling of zipfile archive comments (previously
4373 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004374 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004375
Vinay Sajip51e65192008-07-18 09:01:10 +00004376- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004377 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004378
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004379- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4380 handling is now the same as that of other special attributes like __name__).
4381
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004382- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4383 removal in Python 3.0 in favor of urllib2.urlopen().

4391
Gregory P. Smithc4691ec2008-07-07 05:09:12 +00004392- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
4393 redundant ":443" port number designation when the connection is using the

4395
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00004396- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00004834- Issue #1631171: Re-implement the 'warnings' module in C (the
4835 original Python code has been kept as backup). This will allow for
4836 using the 'warning's machinery in such places as the parser where
4837 use of pure Python code is not possible. Both the ``showarning()``
4838 and ``formatwarning()`` gain an optional 'line' argument which is
4839 not called by default for backwards-compatibility reasons. Setting
4840 ``warnings.showwarning()`` to an implementation that lacks support
4841 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Issue #2550: The approach used by client/server code for obtaining
4905 ports to listen on in network-oriented tests has been refined in an
4906 effort to facilitate running multiple instances of the entire
4907 regression test suite in parallel without issue.
4908 test_support.bind_port() has been fixed such that it will always
4909 return a unique port -- which wasn't always the case with the
4910 previous implementation, especially if socket options had been set
4911 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4912 new implementation of bind_port() will actually raise an exception
4913 if it is passed an AF_INET/SOCK_STREAM socket with either the
4914 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4915 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4916 the socket it's been passed. This currently only applies to
4917 Windows. This option prevents any other sockets from binding to the
4918 host/port we've bound to, thus removing the possibility of the
4919 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4920 when a second SOCK_STREAM socket binds and accepts to a host/port
4921 that's already been bound by another socket. The optional preferred
4922 port parameter to bind_port() has been removed. Under no
4923 circumstances should tests be hard coding ports!
4924
4925 test_support.find_unused_port() has also been introduced, which will
4926 pass a temporary socket object to bind_port() in order to obtain an
4927 unused port. The temporary socket object is then closed and
4928 deleted, and the port is returned. This method should only be used
4929 for obtaining an unused port in order to pass to an external program
4930 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4931 a parameter to a server-oriented class that doesn't give you direct
4932 access to the underlying socket used.
4933
4934 Finally, test_support.HOST has been introduced, which should be used
4935 for the host argument of any relevant socket calls (i.e. bind and
4936 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004937
4938 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004939 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004940 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4941 test_asynchat and test_socket_ssl.
4942
Georg Brandl3ee81df2008-05-17 18:14:43 +00004943 It is now possible for multiple instances of the regression test
4944 suite to run in parallel without issue.

5100 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00005101 platform.machine() and platform.processor() will report this
5102 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00005223- Added the future_builtins module, which contains hex() and oct().
5224 These are the PEP 3127 version of these functions, designed to be
5225 compatible with the hex() and oct() builtins from Python 3.0. They
5226 differ slightly in their output formats from the existing, unchanged
5227 Python 2.6 builtins. The expected usage of the future_builtins
5228 module is:
5229 from future_builtins import hex, oct
5230
Eric Smith7ef40bf2008-02-20 23:34:22 +00005231- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5232 exponents for exponents with absolute value < 100. Follows C99
5233 standard. This is a change on Windows, which would use 3 digits.
5234 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5235 so that any alterations it does to the resulting string will be
5236 available in stringlib/formatter.h (for float.__format__).
5237
Eric Smith5a3c1352008-02-19 13:21:56 +00005238- Implemented PEP 3101, Advanced String Formatting. This adds a new
5239 builtin format(); a format() method for str and unicode; a
5240 __format__() method to object, str, unicode, int, long, float, and
5241 datetime; the class string.Formatter; and the C API
5242 PyObject_Format().
5243
Georg Brandl3ee81df2008-05-17 18:14:43 +00005244- Fixed several potential crashes, all caused by specially crafted
5245 __del__ methods exploiting objects in temporarily inconsistent
5246 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005247
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005248- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005249 prevent a possible crash: an Abstract Base Class would try to access
5250 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005255- Clear all free lists during a gc.collect() of the highest generation
5256 in order to allow pymalloc to free more arenas. Python may give back
5257 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005258
Georg Brandl3ee81df2008-05-17 18:14:43 +00005259- Issue #2045: Fix an infinite recursion triggered when printing a
5260 subclass of collections.defaultdict, if its default_factory is set
5261 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005262
Christian Heimesf75dbef2008-02-08 00:11:31 +00005263- Fixed a minor memory leak in dictobject.c. The content of the free
5264 list was not freed on interpreter shutdown.
5265
Georg Brandl21e99f42010-03-07 15:23:59 +00005266- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5270 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005271 to compact the internal free lists of pre-allocted ints and floats.
5272
Georg Brandl3ee81df2008-05-17 18:14:43 +00005273- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5274 calls. Python expected the return type int but the fork familie
5275 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005276

Georg Brandl3ee81df2008-05-17 18:14:43 +00005289- Patch #1473257: generator objects gain a gi_code attribute. This is
5290 the same object as the func_code attribute of the function that
5291 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005292
Georg Brandl3ee81df2008-05-17 18:14:43 +00005293- Issue #1920: "while 0" statements were completely removed by the
5294 compiler, even in the presence of an "else" clause, which is
5295 supposed to be run when the condition is false. Now the compiler
5296 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005297
Guido van Rossumeead05f2008-01-24 18:21:02 +00005298- A few crashers fixed: weakref_in_del.py (issue #1377858);
5299 loosing_dict_ref.py (issue #1303614, test67.py);
5300 borrowed_ref_[34].py (not in tracker).
5301

5305
Georg Brandl3ee81df2008-05-17 18:14:43 +00005306- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005307 several extension methods and modules do not work without unicode
5308 support.
5309
Georg Brandl26543b12008-01-21 18:36:51 +00005310- Issue #1882: when compiling code from a string, encoding cookies in the

5312
Georg Brandl14404b62008-01-19 19:27:05 +00005313- Issue #1679: "0x" was taken as a valid integer literal.
5314
Georg Brandl6caad7d2008-01-26 14:19:22 +00005315- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005316 added.
5317
Christian Heimesc94e2b52008-01-14 04:13:37 +00005318- sys.float_info / PyFloat_GetInfo: The floating point information
5319 object was converted from a dict to a specialized structseq object.
5320
Georg Brandl3ee81df2008-05-17 18:14:43 +00005321- Patch #1816: Added sys.flags structseq. It exposes the status of
5322 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005323
Georg Brandl3ee81df2008-05-17 18:14:43 +00005324- Objects/structseq.c: Implemented new structseq representation. The

5335
Georg Brandl3ee81df2008-05-17 18:14:43 +00005336- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5337 envvar and sys.dont_write_bytecode attribute. All these can be set
5338 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005339
Georg Brandl3ee81df2008-05-17 18:14:43 +00005340- Improve some exception messages when Windows fails to load an
5341 extension module. Now we get for example '%1 is not a valid Win32
5342 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005349- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005350 and INF. float("nan"), float("inf") and float("-inf") now work on
5351 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005353- Compiler now generates simpler and faster code for dictionary
5354 literals. The oparg for BUILD_MAP now indicates an estimated
5355 dictionary size. There is a new opcode, STORE_MAP, for adding
5356 entries to the dictionary.

5386 file can now be directly executed by passing their name to the
5387 interpreter. The directory/zipfile is automatically inserted as the
5388 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005390- Issue #1265: Fix a problem with sys.settrace, if the tracing
5391 function uses a generator expression when at the same time the
5392 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005393

5399
Georg Brandl21e99f42010-03-07 15:23:59 +00005400- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005401 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5402 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005403
Georg Brandl3ee81df2008-05-17 18:14:43 +00005404- Issue #1686386: Tuple's tp_repr did not take into account the
5405 possibility of having a self-referential tuple, which is possible
5406 from C code. Nor did object's tp_str consider that a type's tp_str
5407 could do something that could lead to an inifinite recursion.
5408 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5409 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005410
Georg Brandl3ee81df2008-05-17 18:14:43 +00005411- Issue #1164: It was possible to trigger deadlock when using the
5412 'print' statement to write to a file since the GIL was not released
5413 as needed. Now PyObject_Print() does the right thing along with
5414 various tp_print implementations of the built-in types and those in
5415 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005416
Georg Brandl3ee81df2008-05-17 18:14:43 +00005417- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00005423
Brett Cannon1e534b52007-09-07 04:18:30 +00005424- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425 PyObject_Call() never calling back out to Python code to trigger
5426 recursion depth updates/checks. Required the creation of a static
5427 RuntimeError instance in case normalizing an exception put the
5428 recursion check value past its limit. Fixes crashers
5429 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005430

Neal Norwitz0ac60192007-05-27 04:08:54 +00005444- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445 __*__ attributes. (Some already existed, e.g., __doc__ and
5446 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005447
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005448- Add -3 option to the interpreter to warn about features that are
5449 deprecated and will be changed/removed in Python 3.0.
5450
Georg Brandl2134e752007-05-21 20:34:16 +00005451- Patch #1686487: you can now pass any mapping after '**' in function
5452 calls.
5453
Collin Winter62903052007-05-18 23:11:24 +00005454- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005455 "except E as target:". This is to provide forwards compatibility
5456 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005463- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005464 setting a plain string, ie don't expand to single letter identifiers.
5465
Raymond Hettinger13936692007-04-11 18:40:58 +00005466- Request #1191699: Slices can now be pickled.
5467
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005468- Request #1193128: str.translate() now allows a None argument for
5469 translations that only remove characters without re-mapping the
5470 remaining characters.
5471
Georg Brandl5cb76c12007-03-21 09:00:39 +00005472- Patch #1682205: a TypeError while unpacking an iterable is no longer

5476
Guido van Rossum143b5642007-03-23 04:58:42 +00005477- Bug #1683368: The object.__init__() and object.__new__() methods are
5478 now stricter in rejecting excess arguments. The only time when
5479 either allows excess arguments is when it is not overridden and the
5480 other one is. For backwards compatibility, when both are
5481 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005482 warning later). Also, type.__init__() insists on the same signature
5483 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005484
Georg Brandl3ee81df2008-05-17 18:14:43 +00005485- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5486 object to complex using its __complex__() method before falling back
5487 to the __float__() method. Therefore, the functions in the cmath
5488 module now can operate on objects that define a __complex__()
5489 method.

5506
Georg Brandl7b9c5552007-03-12 14:30:05 +00005507- Bug #1678647: write a newline after printing an exception in any
5508 case, even when converting the value to a string failed.
5509
Georg Brandl871f1bc2007-03-12 13:17:36 +00005510- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005511 its argument, if it exists. If not, it will work like before. This
5512 allows customizing the output of dir() in the presence of a
5513 __getattr__().

5522 parthensized forms. This means complex(repr(x)) now works instead of
5523 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005524
Georg Brandlaa2321b2007-03-07 00:40:28 +00005525- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526 makes the filenames the warning module prints much more sensible
5527 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005540- Patch #1674228: when assigning a slice (old-style), check for the
5541 sq_ass_slice instead of the sq_slice slot.
5542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543- When printing an unraisable error, don't print exceptions. before
5544 the name. This duplicates the behavior whening normally printing
5545 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006078 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00006080

Georg Brandl92a6bae2007-03-13 17:43:32 +00006112- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006113 are set for invalid interpolation sequences that would lead to
6114 errors on reading back those values.

6170 TestCase and TestSuite subclasses (not instances) are no longer
6171 accepted in TestSuite.addTest(). This should cause no
6172 incompatibility since it never made sense with ordinary subclasses
6173 -- the failure just occurred later, with a more cumbersome
6174 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006563 time so that opening a database previously created with the DB_DUP
6564 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6565 opens. Specifically: dictionary assignment to a DB object will
6566 replace all values for a given key when the database allows
6567 duplicate values. DB users should use DB.put(k, v) when they want
6568 to store duplicates; not DB[k] = v.

6577 behavior of quoting dots if they are the second character of any
6578 line.

6924 of w# format code incorrectly truncated the length to an int, even
6925 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6926 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006956- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6957 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
