232 This prevents user-created self-referencing ordered dictionaries from
233 becoming permanently uncollectable GC garbage. The downside is that
234 removing __del__ means that the internal doubly-linked list has to wait for
235 GC collection rather than freeing memory immediately when the refcnt drops
236 to zero.
237
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000238- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000240 value.
241
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000242- Issue #9792: In case of connection failure, socket.create_connection()
243 would swallow the exception and raise a new one, making it impossible
244 to fetch the original errno, or to filter timeout errors. Now the
245 original error is re-raised.
246
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000247- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
248 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
249 be updated back after the system call. Original patch by Brian Brazil.
250
Antoine Pitroudca9de92010-09-04 17:52:26 +0000251- Issue #1100562: Fix deep-copying of objects derived from the list and
252 dict types. Patch by Michele Orrù and Björn Lindqvist.
253

255 ConfigParser.write.
256
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000257- Issue #808164: Fixed socket.close to avoid references to globals, to
258 avoid issues when socket.close is called from a __del__ method.
259
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000260- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

262 heuristic. Patch by Terry Reedy and Eli Bendersky

265 falling into recursion.
266
R. David Murray7c4bf552010-08-25 01:45:57 +0000267- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
268 character years even if the message contains RFC822 two character years.
269
Daniel Stutzbach91287322010-08-24 21:09:30 +0000270- Issue #8750: Fixed MutableSet's methods to correctly handle
271 reflexive operations, namely x -= x and x ^= x.
272
Victor Stinnercaafd772010-09-08 10:51:01 +0000273- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

283
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000284- Issue #9617: Signals received during a low-level write operation aren't
285 ignored by the buffered IO layer anymore.
286
Benjamin Peterson52c36052010-08-21 03:03:22 +0000287- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
288 are not held onto after they are deleted elsewhere.
289
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000290- Issue #9626: the view methods for collections.OrderedDict() were returning
291 the unordered versions inherited from dict. Those methods are now

305 patch by Jason V. Miller.
306
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000307- Issue #9551: Don't raise TypeError when setting the value to None for

696 of the number of bytes specified by the start byte.
697 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
698 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1096 with a non-empty format string. This is an effort to future-proof user
1097 code. If a derived class does not currently implement __format__ but later
1098 adds its own __format__, it would most likely break user code that had
1099 supplied a format string. This will be changed to a DeprecationWaring in

Mark Dickinson8a950712010-04-03 15:47:46 +00001135
1136 >>> Decimal(1.1)
1137 Decimal('1.100000000000000088817841970012523233890533447265625')
1138
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001139- collections.Counter() now supports a subtract() method.
1140
Georg Brandlfee0f442010-05-22 21:26:21 +00001141- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001150- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1151 InvalidOperation instead of returning False. (Comparisons involving a quiet
1152 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1153 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001155- Issue #2531: Comparison operations between floats and Decimal instances now
1156 return a result based on the numeric values of the operands; previously they
1157 returned an arbitrary result based on the relative ordering of id(float) and
1158 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001160- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001161 argument `-` which tells it to read files to compile from stdin. Each line is
1162 read on demand and the named file is compiled immediately. (Original patch by
1163 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001172- Comparisons using one of <, <=, >, >= between a complex instance and a
1173 Fractions instance now raise TypeError instead of returning True/False. This
1174 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1175 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001279- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1280 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001282 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1283 inconsistent: __int__ was used for some integer codes but not for others, and
1284 the set of integer codes for which it was used differed between native packing
1285 and standard packing.)

1590 position to the given argument, which goes against the tradition of

1594 class used to represent files stored inside an archive. The new
1595 implementation is significantly faster and can be wrapped in a

1609 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1610 encoded string for them. This ensures that the upload and register commands
1611 send the correct values to PyPI without any error.

1693
Mark Dickinson1b34d252010-01-01 17:27:30 +00001694- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001695 DeprecationWarning when passed a float argument where an integer was expected.
1696 These functions and methods now raise TypeError instead. The majority of the
1697 effects of this change are in the extension modules, but some core functions
1698 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1699 and many unicode/str methods.

1714 least on IEEE 754 platforms), and in particular does not depend on the
1715 internal representation of a long.

1723
Georg Brandlba83f822010-03-14 09:50:54 +00001724 These executables now work properly with the arch(1) command: ``arch -ppc
1725 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001861- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1862 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001863
Georg Brandlba83f822010-03-14 09:50:54 +00001864- Issue #3382: 'F' formatting for float and complex now convert the result to
1865 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1866 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001867
Georg Brandlba83f822010-03-14 09:50:54 +00001868- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1869 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001870
Georg Brandlba83f822010-03-14 09:50:54 +00001871- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1872 1e-100 used to raise OverflowError, but now gives the requested 120
1873 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001874
Georg Brandlba83f822010-03-14 09:50:54 +00001875- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001878
Georg Brandlba83f822010-03-14 09:50:54 +00001879- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1880 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001881
Georg Brandlba83f822010-03-14 09:50:54 +00001882- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1883 decimal string that's guaranteed to round back to x under correct rounding
1884 (with round-half-to-even rounding mode). Previously it gave a string based on
1885 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1886 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1887 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001888
Georg Brandlba83f822010-03-14 09:50:54 +00001889- Issue #7117: On almost all platforms: float-to-string and string-to-float
1890 conversions within Python are now correctly rounded. Places these conversions
1891 occur include: str for floats and complex numbers; the float and complex
1892 constructors; old-style and new-style numeric formatting; serialization and
1893 deserialization of floats and complex numbers using marshal, pickle and json;
1894 parsing of float and imaginary literals in Python code; Decimal-to-float
1895 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001896
Georg Brandlba83f822010-03-14 09:50:54 +00001897 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1898 providing correctly-rounded strtod and dtoa C functions. This code is
1899 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1900 the C compiler. There may be a small number of platforms on which correct
1901 operation of this code cannot be guaranteed, so the code is not used: notably,
1902 this applies to platforms where the C double format is not IEEE 754 binary64,
1903 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1904 and Python's configure script is unable to determine how to change the FPU
1905 precision. On these platforms conversions use the platform strtod and dtoa,
1906 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001907
Georg Brandlba83f822010-03-14 09:50:54 +00001908- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1909 uses the correctly-rounded string <-> float conversions described above (when
1910 available), and so produces correctly rounded results that will display nicely
1911 under the float repr. There are two related small changes: (1) round now
1912 accepts any class with an ``__index__()`` method for its second argument (but
1913 no longer accepts floats for the second argument), and (2) an excessively
1914 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1915 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00001917- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1918
Georg Brandlba83f822010-03-14 09:50:54 +00001919- Fix several issues with ``compile()``. The input can now contain Windows and
1920 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001921

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00001950- Issue #1571184: The Unicode database contains properties for more characters.
1951 The tables for code points representing numeric values, white spaces or line
1952 breaks are now generated from the official Unicode Character Database files,
1953 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00002062- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2063 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2064 but with at least one decimal point and with a default precision
2065 of 12. Previously, the behavior the same but with a default precision of 6.
2066 This more closely matches ``str()``, and reduces surprises when adding

3694-----------------
3695
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003696- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3697
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003698- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3699 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3700 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3701 ``printf`` function, whereas PyString_FromFormat has an independent
3702 implementation and uses "%zd" on all platforms for size_t values.
3703 This makes a difference on win64, where ``printf`` needs "%Id" to display
3704 64bit values.
3705
Benjamin Peterson97179b02008-09-09 20:55:01 +00003706- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3707 error.
3708
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003709- Issue #3777: long() applied to a float object now always return a long
3710 object; previously an int would be returned for small values. the __long__
3711 method is allowed to return either an int or a long, but the behaviour of
3712 float objects should not change to respect backward compatibility.
3713
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003714- Issue #3751: str.rpartition would perform a left-partition when called with
3715 a unicode argument.
3716
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003717- Issue #3683: Fix compilation when --without-threads is given.
3718
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003719- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003720 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003721 was correctly parsed but parsing of subsequent arguments failed.
3722
Vinay Sajip35e3b032008-09-01 14:33:59 +00003723- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003724 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3725 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3726 when given a tuple of classes as second argument, were looking up
3727 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3728 type object.
3729
Neal Norwitz18aa3882008-08-24 05:04:52 +00003730- Fix crashes on memory allocation failure found with failmalloc.
3731
3732- Fix memory leaks found with valgrind and update suppressions file.
3733
3734- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3735
3736- Fix problem using wrong name in decimal module reported by pychecker.
3737
Christian Heimes7d4c3172008-08-22 19:47:25 +00003738- Silenced another compiler warning about a used but not defined
3739 function 'stringlib_contains_obj'.
3740
Benjamin Peterson712ee922008-08-24 18:10:20 +00003741- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3742 ``__delslice__``.
3743
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003744- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3745 library targets in the Makefile.
3746
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003747- Issue #1204: The configure script now tests for additional libraries
3748 that may be required when linking against readline. This fixes issues
3749 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3750
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00003751C-API

3758
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003759- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3760 stack usage in the case of deeply nested objects.
3761

Nick Coghland2e09382008-09-11 12:11:06 +00003772- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003773 return a list or None rather than a custom object.
3774
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003775- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3776
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003777- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon32476fc2008-09-05 18:33:51 +00003780
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00003781- Issue #3762: platform.architecture() fails if python is lanched via
3782 its symbolic link.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003799 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3800 for catch_warnings() also led to an improvement in the raising of a
3801 DeprecationWarning related to warnings.warn_explicit().
3802
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003803- The deprecation warnings for the old camelCase threading API were removed.

3825
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003826- Issue #2975: When compiling several extension modules with Visual Studio 2008
3827 from the same python interpreter, some environment variables would grow
3828 without limit.
3829
Benjamin Peterson37346b22008-08-23 20:27:43 +00003830- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3831 exploitation of poor argument checking.
3832
Gerhard Häringef2276b2008-09-12 13:54:06 +00003833- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003835- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3836 remaining ones have "pysqlite_" prefix.
3837
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003838- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00003845- Issue #3781: Add test.test_support.check_warnings() as a convenience
3846 wrapper for warnings.catch_warnings() that makes it easier to check
3847 that expected warning messages are being reported.
3848
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003849- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003871
3872Core and Builtins
3873-----------------
3874
Guido van Rossumf8402962008-08-20 15:01:50 +00003875- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3876 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3877 extensions do not automatically benefit from the class attribute
3878 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3879 to their tp_flags field if they care. This is a backwards
3880 compatibility feature; in 3.0, all types will use the cache by
3881 default.
3882
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003883- Keyword arguments can now follow starred arguments. (``f(a, *args,
3884 keyword=23)`` is now valid syntax.)
3885
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003886- ctypes function pointers that are COM methods have a boolean True
3887 value again.
3888
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003889- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3890 by denying s# to parse objects that have a releasebuffer procedure,
3891 and introducing s*.
3892
Georg Brandl1e13ea92008-08-11 09:07:59 +00003893- Issue #3537: Fix an assertion failure when an empty but presized dict
3894 object was stored in the freelist.
3895
Mark Dickinsonb6467572008-08-04 21:30:09 +00003896- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3897 ValueError consistently across platforms.
3898
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003899- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3900 (64bit Unix, for example), unichr() would truncate its argument and return
3901 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3902
Neal Norwitze7d8be82008-07-31 17:17:14 +00003903- Apply security patches from Apple.
3904
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003905- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3906 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3907
Antoine Pitrou92f82162008-07-25 22:22:08 +00003908- Issue #1819: function calls with several named parameters are now on
3909 average 35% faster (as measured by pybench).
3910
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003911- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3912 the python debugger steps into a class statement: the free variables (local
3913 variables defined in an outer scope) would be deleted from the outer scope.
3914
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003915- Issue #2620: Overflow checking when allocating or reallocating memory
3916 was not always being done properly in some python types and extension
3917 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3918 all been updated to perform better checks and places in the code that
3919 would previously leak memory on the error path when such an allocation
3920 failed have been fixed.

3923-------
3924
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003925- Issue #3612: Added some missing basic types in ctypes.wintypes.
3926
Benjamin Petersone977ad42008-08-20 01:42:01 +00003927- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3928 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3929
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003930- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3931 version reported by these tools does not necessarily follow the python
3932 version numbering scheme, so the module is less strict when parsing it.
3933
Nick Coghlanf70385a2008-08-18 12:42:46 +00003934- Issue #2235: Added Py3k warnings for types which will become unhashable
3935 under the stricter __hash__ inheritance rules in 3.0. Several types
3936 which did not meet the rules for hash invariants and were already
3937 unhashable in 3.0 have now been explicitly flagged as unhashable in
3938 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3939 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3940
Brett Cannon88f801d2008-08-18 00:46:22 +00003941- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3942 imported into the module but exposed as part of the module's API.
3943
Brett Cannon7b96f072008-08-18 00:41:11 +00003944- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3949
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003950- Issue #3575: Incremental decoder's decode function now takes bytearray
3951 by using 's*' instead of 't#'.
3952
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003953- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003954 fails unicode conversion on 2nd parameter. (windows only)
3955
Georg Brandl222e2082010-08-01 22:27:39 +00003956- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003957 in a redirect.
3958
Brett Cannonabe423e2008-08-16 21:47:07 +00003959- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003960 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003961
Facundo Batistaeb90b782008-08-16 14:44:07 +00003962- Issue #2776: fixed small issue when handling an URL with double slash
3963 after a 302 response in the case of not going through a proxy.
3964
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003965- Issue #2676: in the email package, content-type parsing was hanging on
3966 pathological input because of quadratic or exponential behaviour of a
3967 regular expression.
3968
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003969- Issue #3476: binary buffered reading through the new "io" library is now
3970 thread-safe.
3971
Brett Cannonbf3157b2008-08-14 05:00:03 +00003972- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3973 since mimetools itself is deprecated. Because modules are cached, all
3974 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3975

Antoine Pitroude781a42008-08-09 12:43:23 +00004010 asking for a specific length. This problem only affected files opened

4054
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004055- Issue #643841: The language reference now provides more detailed

4067-----------------
4068
Georg Brandl3e483f62008-07-16 22:57:41 +00004069- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4070 its methods now allow for items objects that can be converted to
4071 an integer using operator.index().
4072
Mark Dickinson64b7e502008-07-16 09:40:03 +00004073- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4074 produced a ValueError instead of giving the correct float.
4075
Eric Smitha5fa5a22008-07-16 00:11:49 +00004076- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4077 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4078
Mark Dickinson7103aa42008-07-15 19:08:33 +00004079- Issue #3008: the float type has a new instance method 'float.hex'
4080 and a new class method 'float.fromhex' to convert floating-point
4081 numbers to and from hexadecimal strings, respectively.
4082
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004083- Issue #2235: __hash__ is once again inherited by default. To allow
4084 collections.Hashable to remain meaningful in the presence of the
4085 default hash implementation (object.__hash__), it is now possible
4086 to explicit block inheritance of hash by setting __hash__=None at
4087 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4088 level.
4089
Nick Coghlanb028f502008-07-13 14:52:36 +00004090- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4091 the parent module cannot be found while performing an absolute import.
4092 This means that an incorrectly defined __package__ attribute will
4093 now only prevent relative imports in that module rather than causing
4094 all imports from that module to fail.
4095
Nick Coghlan14ff9942008-07-08 14:21:42 +00004096- Issue #2517: Allow unicode messages in Exceptions again by correctly

4106 another thread's dictionary.
4107
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004108- Issue #3004: Minor change to slice.indices(): the start and stop
4109 arguments are now treated identically, making the behaviour easier
4110 to describe and understand. For example, slice(None, -10,
4111 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4112 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4113 10, -1).
4114
Georg Brandl278fc502008-07-19 12:46:12 +00004115- Issue #3219: Calling a function with repeated keyword arguments,
4116 f(a=2, a=23), would not cause a syntax error. This was a regression
4117 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004119- Issue #2862: Make int and float freelist management consistent with
4120 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004155- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4156 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004157 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004158 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004174- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4543 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00004544
Vinay Sajip9828b7e2008-06-17 11:04:02 +00004545- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004546 environment to control the '-arch' flags that are used to build
4547 an extension. This was added for compatibility with Apple's build
4548 of Python.
4549
4550- The bundled OSX-specific copy of libbffi is now in sync with the version
4551 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4552
Georg Brandl25c34082008-08-18 23:09:49 +00004553- The threading module gained aliases for names that will be removed in the

4562
Brett Cannonb61d8012008-05-11 23:39:04 +00004563- ``Lib/lib-old`` is now added to sys.path.
4564
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004565- On MacOS X it is now possible to install the framework in 64-bit
4566 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004567 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004568
4569 This is controlled by the configure argument ``--with-universal-archs``:
4570
4571 - ``--with-universal-archs=all``: install 4-way universal
4572
4573 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4574
4575 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4576
4577 This option should be used in combination with ``--enable-universalsdk=``.
4578
4579 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004588
4589- The PyString functions have been renamed to PyBytes. A batch of
4590 defines were added so that the linker still sees the original
4591 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004629- Issue #1631171: Re-implement the 'warnings' module in C (the
4630 original Python code has been kept as backup). This will allow for
4631 using the 'warning's machinery in such places as the parser where
4632 use of pure Python code is not possible. Both the ``showarning()``
4633 and ``formatwarning()`` gain an optional 'line' argument which is
4634 not called by default for backwards-compatibility reasons. Setting
4635 ``warnings.showwarning()`` to an implementation that lacks support
4636 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004661- The getpass module has been improved on Unix. It now uses /dev/tty
4662 by default and uses stderr instead of stdout. A GetPassWarning is
4663 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004678- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004679 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- Issue #2550: The approach used by client/server code for obtaining
4700 ports to listen on in network-oriented tests has been refined in an
4701 effort to facilitate running multiple instances of the entire
4702 regression test suite in parallel without issue.
4703 test_support.bind_port() has been fixed such that it will always
4704 return a unique port -- which wasn't always the case with the
4705 previous implementation, especially if socket options had been set
4706 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4707 new implementation of bind_port() will actually raise an exception
4708 if it is passed an AF_INET/SOCK_STREAM socket with either the
4709 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4710 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4711 the socket it's been passed. This currently only applies to
4712 Windows. This option prevents any other sockets from binding to the
4713 host/port we've bound to, thus removing the possibility of the
4714 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4715 when a second SOCK_STREAM socket binds and accepts to a host/port
4716 that's already been bound by another socket. The optional preferred
4717 port parameter to bind_port() has been removed. Under no
4718 circumstances should tests be hard coding ports!
4719
4720 test_support.find_unused_port() has also been introduced, which will
4721 pass a temporary socket object to bind_port() in order to obtain an
4722 unused port. The temporary socket object is then closed and
4723 deleted, and the port is returned. This method should only be used
4724 for obtaining an unused port in order to pass to an external program
4725 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4726 a parameter to a server-oriented class that doesn't give you direct
4727 access to the underlying socket used.
4728
4729 Finally, test_support.HOST has been introduced, which should be used
4730 for the host argument of any relevant socket calls (i.e. bind and
4731 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004732
4733 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004734 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004735 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4736 test_asynchat and test_socket_ssl.
4737
Georg Brandl3ee81df2008-05-17 18:14:43 +00004738 It is now possible for multiple instances of the regression test
4739 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005018- Added the future_builtins module, which contains hex() and oct().
5019 These are the PEP 3127 version of these functions, designed to be
5020 compatible with the hex() and oct() builtins from Python 3.0. They
5021 differ slightly in their output formats from the existing, unchanged
5022 Python 2.6 builtins. The expected usage of the future_builtins
5023 module is:
5024 from future_builtins import hex, oct
5025
Eric Smith7ef40bf2008-02-20 23:34:22 +00005026- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5027 exponents for exponents with absolute value < 100. Follows C99
5028 standard. This is a change on Windows, which would use 3 digits.
5029 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5030 so that any alterations it does to the resulting string will be
5031 available in stringlib/formatter.h (for float.__format__).
5032
Eric Smith5a3c1352008-02-19 13:21:56 +00005033- Implemented PEP 3101, Advanced String Formatting. This adds a new
5034 builtin format(); a format() method for str and unicode; a
5035 __format__() method to object, str, unicode, int, long, float, and
5036 datetime; the class string.Formatter; and the C API
5037 PyObject_Format().
5038
Georg Brandl3ee81df2008-05-17 18:14:43 +00005039- Fixed several potential crashes, all caused by specially crafted
5040 __del__ methods exploiting objects in temporarily inconsistent
5041 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00005043- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044 prevent a possible crash: an Abstract Base Class would try to access
5045 a slot on a registered virtual subclass.

5048 real or imaginary part.

5051 in order to allow pymalloc to free more arenas. Python may give back
5052 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005053
Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Issue #2045: Fix an infinite recursion triggered when printing a
5055 subclass of collections.defaultdict, if its default_factory is set
5056 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005057
Christian Heimesf75dbef2008-02-08 00:11:31 +00005058- Fixed a minor memory leak in dictobject.c. The content of the free
5059 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00005061- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005062 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005063
Georg Brandl3ee81df2008-05-17 18:14:43 +00005064- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5065 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005066 to compact the internal free lists of pre-allocted ints and floats.
5067
Georg Brandl3ee81df2008-05-17 18:14:43 +00005068- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5069 calls. Python expected the return type int but the fork familie
5070 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005071
Georg Brandl3ee81df2008-05-17 18:14:43 +00005072- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5073 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005074
Georg Brandl3ee81df2008-05-17 18:14:43 +00005075- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5076 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005077
Georg Brandl3ee81df2008-05-17 18:14:43 +00005078- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5079 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005081- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5082 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005083
Georg Brandl3ee81df2008-05-17 18:14:43 +00005084- Patch #1473257: generator objects gain a gi_code attribute. This is
5085 the same object as the func_code attribute of the function that
5086 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005087
Georg Brandl3ee81df2008-05-17 18:14:43 +00005088- Issue #1920: "while 0" statements were completely removed by the
5089 compiler, even in the presence of an "else" clause, which is
5090 supposed to be run when the condition is false. Now the compiler
5091 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005092
Guido van Rossumeead05f2008-01-24 18:21:02 +00005093- A few crashers fixed: weakref_in_del.py (issue #1377858);
5094 loosing_dict_ref.py (issue #1303614, test67.py);
5095 borrowed_ref_[34].py (not in tracker).
5096
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005097- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005098 suppressed while an extension is loaded by calling SetErrorMode in
5099 dynload_win.c. The error is still reported properly.
5100
Georg Brandl3ee81df2008-05-17 18:14:43 +00005101- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005102 several extension methods and modules do not work without unicode
5103 support.
5104
Georg Brandl26543b12008-01-21 18:36:51 +00005105- Issue #1882: when compiling code from a string, encoding cookies in the
5106 second line of code were not always recognized correctly.
5107
Georg Brandl14404b62008-01-19 19:27:05 +00005108- Issue #1679: "0x" was taken as a valid integer literal.
5109
Georg Brandl6caad7d2008-01-26 14:19:22 +00005110- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005111 added.
5112
Christian Heimesc94e2b52008-01-14 04:13:37 +00005113- sys.float_info / PyFloat_GetInfo: The floating point information
5114 object was converted from a dict to a specialized structseq object.
5115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- Patch #1816: Added sys.flags structseq. It exposes the status of
5117 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005118
Georg Brandl3ee81df2008-05-17 18:14:43 +00005119- Objects/structseq.c: Implemented new structseq representation. The
5120 patch makes structseqs (e.g. the return value of os.stat) more
5121 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005122
Georg Brandl3ee81df2008-05-17 18:14:43 +00005123- Patch #1700288: added a type attribute cache that caches method
5124 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005125
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005126- Bug #1776: __import__() no longer accepts filenames on any platform.
5127 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005128
Georg Brandlaed6c662008-01-07 17:25:53 +00005129- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5130
Georg Brandl3ee81df2008-05-17 18:14:43 +00005131- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5132 envvar and sys.dont_write_bytecode attribute. All these can be set
5133 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005134
Georg Brandl3ee81df2008-05-17 18:14:43 +00005135- Improve some exception messages when Windows fails to load an
5136 extension module. Now we get for example '%1 is not a valid Win32
5137 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005138
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5142 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005143
Christian Heimes0a8143f2007-12-18 23:22:54 +00005144- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145 and INF. float("nan"), float("inf") and float("-inf") now work on
5146 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Compiler now generates simpler and faster code for dictionary
5149 literals. The oparg for BUILD_MAP now indicates an estimated
5150 dictionary size. There is a new opcode, STORE_MAP, for adding
5151 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005161- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005162 SystemError.
5163
Nick Coghlanef01d822007-12-03 12:55:17 +00005164- PEP 366: Allow explicit relative imports when executing modules
5165 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Patch #1739468: Directories and zipfiles containing a __main__.py
5181 file can now be directly executed by passing their name to the
5182 interpreter. The directory/zipfile is automatically inserted as the
5183 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005184
Georg Brandl3ee81df2008-05-17 18:14:43 +00005185- Issue #1265: Fix a problem with sys.settrace, if the tracing
5186 function uses a generator expression when at the same time the
5187 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005188
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005189- sets and frozensets now have an isdisjoint() method.
5190
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005191- optimize the performance of builtin.sum().
5192
Neal Norwitz44f326e2007-10-05 05:29:17 +00005193- Fix warnings found by the new version of the Coverity checker.
5194
Georg Brandl21e99f42010-03-07 15:23:59 +00005195- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5197 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005198
Georg Brandl3ee81df2008-05-17 18:14:43 +00005199- Issue #1686386: Tuple's tp_repr did not take into account the
5200 possibility of having a self-referential tuple, which is possible
5201 from C code. Nor did object's tp_str consider that a type's tp_str
5202 could do something that could lead to an inifinite recursion.
5203 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5204 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005205
Georg Brandl3ee81df2008-05-17 18:14:43 +00005206- Issue #1164: It was possible to trigger deadlock when using the
5207 'print' statement to write to a file since the GIL was not released
5208 as needed. Now PyObject_Print() does the right thing along with
5209 various tp_print implementations of the built-in types and those in
5210 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005211
Georg Brandl3ee81df2008-05-17 18:14:43 +00005212- Issue #1147: Exceptions were directly allowing string exceptions in
5213 their throw() method even though string exceptions no longer
5214 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005215
Georg Brandl3ee81df2008-05-17 18:14:43 +00005216- Issue #1096: Prevent a segfault from getting the repr of a very
5217 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005218
Brett Cannon1e534b52007-09-07 04:18:30 +00005219- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005220 PyObject_Call() never calling back out to Python code to trigger
5221 recursion depth updates/checks. Required the creation of a static
5222 RuntimeError instance in case normalizing an exception put the
5223 recursion check value past its limit. Fixes crashers
5224 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005225
Georg Brandl3ee81df2008-05-17 18:14:43 +00005226- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005239- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240 __*__ attributes. (Some already existed, e.g., __doc__ and
5241 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005242
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005243- Add -3 option to the interpreter to warn about features that are
5244 deprecated and will be changed/removed in Python 3.0.
5245
Georg Brandl2134e752007-05-21 20:34:16 +00005246- Patch #1686487: you can now pass any mapping after '**' in function
5247 calls.
5248
Collin Winter62903052007-05-18 23:11:24 +00005249- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005250 "except E as target:". This is to provide forwards compatibility
5251 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00005253- Deprecate BaseException.message as per PEP 352.
5254
Georg Brandl3ee81df2008-05-17 18:14:43 +00005255- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005256 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005258- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005259 setting a plain string, ie don't expand to single letter identifiers.
5260
Raymond Hettinger13936692007-04-11 18:40:58 +00005261- Request #1191699: Slices can now be pickled.
5262
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005263- Request #1193128: str.translate() now allows a None argument for
5264 translations that only remove characters without re-mapping the
5265 remaining characters.
5266
Georg Brandl5cb76c12007-03-21 09:00:39 +00005267- Patch #1682205: a TypeError while unpacking an iterable is no longer
5268 masked by a generic one with the message "unpack non-sequence".
5269
Neal Norwitzaa754b72007-03-21 06:39:48 +00005270- Remove unused file Python/fmod.c.
5271
Guido van Rossum143b5642007-03-23 04:58:42 +00005272- Bug #1683368: The object.__init__() and object.__new__() methods are
5273 now stricter in rejecting excess arguments. The only time when
5274 either allows excess arguments is when it is not overridden and the
5275 other one is. For backwards compatibility, when both are
5276 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005277 warning later). Also, type.__init__() insists on the same signature
5278 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005279
Georg Brandl3ee81df2008-05-17 18:14:43 +00005280- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5281 object to complex using its __complex__() method before falling back
5282 to the __float__() method. Therefore, the functions in the cmath
5283 module now can operate on objects that define a __complex__()
5284 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006358 time so that opening a database previously created with the DB_DUP
6359 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6360 opens. Specifically: dictionary assignment to a DB object will
6361 replace all values for a given key when the database allows
6362 duplicate values. DB users should use DB.put(k, v) when they want
6363 to store duplicates; not DB[k] = v.

6372 behavior of quoting dots if they are the second character of any
6373 line.
