367 thread-local storage key.

502 fix various SSLSocket methods to raise socket.error rather than an
503 unhelpful TypeError when called on an unconnected socket. Original patch
504 by Andrew Bennetts.

513
Raymond Hettinger20397532010-09-12 02:11:45 +0000514- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
515 This prevents user-created self-referencing ordered dictionaries from
516 becoming permanently uncollectable GC garbage. The downside is that
517 removing __del__ means that the internal doubly-linked list has to wait for
518 GC collection rather than freeing memory immediately when the refcnt drops
519 to zero.
520
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000521- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

524
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000525- Issue #9792: In case of connection failure, socket.create_connection()
526 would swallow the exception and raise a new one, making it impossible
527 to fetch the original errno, or to filter timeout errors. Now the
528 original error is re-raised.
529
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000530- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
531 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
532 be updated back after the system call. Original patch by Brian Brazil.
533
Antoine Pitroudca9de92010-09-04 17:52:26 +0000534- Issue #1100562: Fix deep-copying of objects derived from the list and
535 dict types. Patch by Michele Orrù and Björn Lindqvist.

538 ConfigParser.write.
539
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000540- Issue #808164: Fixed socket.close to avoid references to globals, to
541 avoid issues when socket.close is called from a __del__ method.
542
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000543- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

549
R. David Murray7c4bf552010-08-25 01:45:57 +0000550- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
551 character years even if the message contains RFC822 two character years.
552
Daniel Stutzbach91287322010-08-24 21:09:30 +0000553- Issue #8750: Fixed MutableSet's methods to correctly handle

555

569
Benjamin Peterson52c36052010-08-21 03:03:22 +0000570- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

572
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000573- Issue #9626: the view methods for collections.OrderedDict() were returning
574 the unordered versions inherited from dict. Those methods are now
575 overridden to provide ordered views.
576
Éric Araujo0389ae62010-08-14 03:07:46 +0000577- Issue #8688: MANIFEST files created by distutils now include a magic
578 comment indicating they are generated. Manually maintained MANIFESTs
579 without this marker will not be overwritten or removed.
580
Antoine Pitroue1436d12010-08-12 15:25:51 +0000581- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

584
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000585- Issue #9550: a BufferedReader could issue an additional read when the

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000977- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
978 start byte and the continuation byte(s) are now considered invalid, instead
979 of the number of bytes specified by the start byte.
980 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
981 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
982 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
983 Previous versions returned a single u'\ufffd'.

987 arises from the "Overriding __eq__ blocks inheritance ..." warning

989 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000991- Issue #8748: Fix two issues with comparisons between complex and integer
992 objects. (1) The comparison could incorrectly return True in some cases
993 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
994 (2) The comparison raised an OverflowError for large integers, leading
995 to unpredictable exceptions when combining integers and complex objects
996 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00001189- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1190 operation raises multiple signals and more than one of those signals is
1191 trapped, the specification determines the order in which the signals should be
1192 handled. In many cases this order wasn't being followed, leading to the wrong

1379 with a non-empty format string. This is an effort to future-proof user
1380 code. If a derived class does not currently implement __format__ but later
1381 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001382 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001383 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001433- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1434 InvalidOperation instead of returning False. (Comparisons involving a quiet
1435 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1436 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001438- Issue #2531: Comparison operations between floats and Decimal instances now
1439 return a result based on the numeric values of the operands; previously they
1440 returned an arbitrary result based on the relative ordering of id(float) and
1441 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001443- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001444 argument `-` which tells it to read files to compile from stdin. Each line is
1445 read on demand and the named file is compiled immediately. (Original patch by
1446 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001455- Comparisons using one of <, <=, >, >= between a complex instance and a
1456 Fractions instance now raise TypeError instead of returning True/False. This
1457 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1458 <=> complex, and complex <=> complex comparisons.

1558 integer format code, struct.pack first attempts to convert the non-integer

1561
Georg Brandlba83f822010-03-14 09:50:54 +00001562- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1563 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1564 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001565 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1566 inconsistent: __int__ was used for some integer codes but not for others, and
1567 the set of integer codes for which it was used differed between native packing
1568 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001876 file position when calling `truncate()`. It would previously change the file
1877 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001878 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1881 class used to represent files stored inside an archive. The new
1882 implementation is significantly faster and can be wrapped in a

Georg Brandlba83f822010-03-14 09:50:54 +00002148- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
2149 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00002151- Issue #3382: 'F' formatting for float and complex now convert the result to
2152 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2153 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002154
Georg Brandlba83f822010-03-14 09:50:54 +00002155- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2156 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002157
Georg Brandlba83f822010-03-14 09:50:54 +00002158- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2159 1e-100 used to raise OverflowError, but now gives the requested 120
2160 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002161
Georg Brandlba83f822010-03-14 09:50:54 +00002162- Add Py3k warnings for parameter names in parentheses.

2167 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002168
Georg Brandlba83f822010-03-14 09:50:54 +00002169- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2170 decimal string that's guaranteed to round back to x under correct rounding
2171 (with round-half-to-even rounding mode). Previously it gave a string based on
2172 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2173 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2174 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002175
Georg Brandlba83f822010-03-14 09:50:54 +00002176- Issue #7117: On almost all platforms: float-to-string and string-to-float
2177 conversions within Python are now correctly rounded. Places these conversions
2178 occur include: str for floats and complex numbers; the float and complex
2179 constructors; old-style and new-style numeric formatting; serialization and
2180 deserialization of floats and complex numbers using marshal, pickle and json;
2181 parsing of float and imaginary literals in Python code; Decimal-to-float
2182 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002183
Georg Brandlba83f822010-03-14 09:50:54 +00002184 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2185 providing correctly-rounded strtod and dtoa C functions. This code is
2186 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2187 the C compiler. There may be a small number of platforms on which correct
2188 operation of this code cannot be guaranteed, so the code is not used: notably,
2189 this applies to platforms where the C double format is not IEEE 754 binary64,
2190 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2191 and Python's configure script is unable to determine how to change the FPU
2192 precision. On these platforms conversions use the platform strtod and dtoa,
2193 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002194
Georg Brandlba83f822010-03-14 09:50:54 +00002195- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2196 uses the correctly-rounded string <-> float conversions described above (when
2197 available), and so produces correctly rounded results that will display nicely
2198 under the float repr. There are two related small changes: (1) round now
2199 accepts any class with an ``__index__()`` method for its second argument (but
2200 no longer accepts floats for the second argument), and (2) an excessively
2201 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2202 raises an exception.

2205
Georg Brandlba83f822010-03-14 09:50:54 +00002206- Fix several issues with ``compile()``. The input can now contain Windows and

2238 The tables for code points representing numeric values, white spaces or line
2239 breaks are now generated from the official Unicode Character Database files,
2240 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00002349- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2350 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2351 but with at least one decimal point and with a default precision
2352 of 12. Previously, the behavior the same but with a default precision of 6.
2353 This more closely matches ``str()``, and reduces surprises when adding
2354 alignment flags to the empty presentation type. This also affects the new
2355 complex.__format__ in the same way.

3980Core and Builtins
3981-----------------
3982
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003983- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3984
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003985- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3986 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3987 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3988 ``printf`` function, whereas PyString_FromFormat has an independent
3989 implementation and uses "%zd" on all platforms for size_t values.
3990 This makes a difference on win64, where ``printf`` needs "%Id" to display
3991 64bit values.
3992
Benjamin Peterson97179b02008-09-09 20:55:01 +00003993- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3994 error.
3995
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003996- Issue #3777: long() applied to a float object now always return a long
3997 object; previously an int would be returned for small values. the __long__
3998 method is allowed to return either an int or a long, but the behaviour of
3999 float objects should not change to respect backward compatibility.
4000
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004001- Issue #3751: str.rpartition would perform a left-partition when called with
4002 a unicode argument.
4003
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004004- Issue #3683: Fix compilation when --without-threads is given.
4005
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004006- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004007 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004008 was correctly parsed but parsing of subsequent arguments failed.
4009
Vinay Sajip35e3b032008-09-01 14:33:59 +00004010- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004011 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4012 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4013 when given a tuple of classes as second argument, were looking up
4014 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4015 type object.
4016
Neal Norwitz18aa3882008-08-24 05:04:52 +00004017- Fix crashes on memory allocation failure found with failmalloc.
4018
4019- Fix memory leaks found with valgrind and update suppressions file.
4020
4021- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4022
4023- Fix problem using wrong name in decimal module reported by pychecker.
4024
Christian Heimes7d4c3172008-08-22 19:47:25 +00004025- Silenced another compiler warning about a used but not defined
4026 function 'stringlib_contains_obj'.
4027
Benjamin Peterson712ee922008-08-24 18:10:20 +00004028- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4029 ``__delslice__``.
4030
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004031- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4032 library targets in the Makefile.
4033
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004034- Issue #1204: The configure script now tests for additional libraries
4035 that may be required when linking against readline. This fixes issues
4036 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
4037

4045
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00004046- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
4047 stack usage in the case of deeply nested objects.
4048
Guido van Rossume3c4fd92008-09-10 14:27:00 +00004049- Issue #3629: Fix sre "bytecode" validator for an end case.

Nick Coghland2e09382008-09-11 12:11:06 +00004059- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004060 return a list or None rather than a custom object.
4061
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004062- Issue #1638033: Cookie.Morsel gained the httponly attribute.
4063
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00004064- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004086 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4087 for catch_warnings() also led to an improvement in the raising of a
4088 DeprecationWarning related to warnings.warn_explicit().
4089
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004090- The deprecation warnings for the old camelCase threading API were removed.

4112
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004113- Issue #2975: When compiling several extension modules with Visual Studio 2008
4114 from the same python interpreter, some environment variables would grow
4115 without limit.
4116
Benjamin Peterson37346b22008-08-23 20:27:43 +00004117- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4118 exploitation of poor argument checking.
4119
Gerhard Häringef2276b2008-09-12 13:54:06 +00004120- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004122- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4123 remaining ones have "pysqlite_" prefix.
4124
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004125- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00004132- Issue #3781: Add test.test_support.check_warnings() as a convenience
4133 wrapper for warnings.catch_warnings() that makes it easier to check
4134 that expected warning messages are being reported.
4135
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004136- Issue #3796: Some tests functions were not enabled in test_float.

Barry Warsaw07a4a382008-08-21 01:15:08 +00004157*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004158
4159Core and Builtins
4160-----------------
4161
Guido van Rossumf8402962008-08-20 15:01:50 +00004162- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4163 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4164 extensions do not automatically benefit from the class attribute
4165 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4166 to their tp_flags field if they care. This is a backwards
4167 compatibility feature; in 3.0, all types will use the cache by
4168 default.
4169
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004170- Keyword arguments can now follow starred arguments. (``f(a, *args,
4171 keyword=23)`` is now valid syntax.)
4172
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004173- ctypes function pointers that are COM methods have a boolean True
4174 value again.
4175
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004176- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4177 by denying s# to parse objects that have a releasebuffer procedure,
4178 and introducing s*.
4179
Georg Brandl1e13ea92008-08-11 09:07:59 +00004180- Issue #3537: Fix an assertion failure when an empty but presized dict
4181 object was stored in the freelist.
4182
Mark Dickinsonb6467572008-08-04 21:30:09 +00004183- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4184 ValueError consistently across platforms.
4185
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004186- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4187 (64bit Unix, for example), unichr() would truncate its argument and return
4188 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4189
Neal Norwitze7d8be82008-07-31 17:17:14 +00004190- Apply security patches from Apple.
4191
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004192- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4193 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4194
Antoine Pitrou92f82162008-07-25 22:22:08 +00004195- Issue #1819: function calls with several named parameters are now on
4196 average 35% faster (as measured by pybench).
4197
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004198- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4199 the python debugger steps into a class statement: the free variables (local
4200 variables defined in an outer scope) would be deleted from the outer scope.
4201
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004202- Issue #2620: Overflow checking when allocating or reallocating memory
4203 was not always being done properly in some python types and extension
4204 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4205 all been updated to perform better checks and places in the code that
4206 would previously leak memory on the error path when such an allocation
4207 failed have been fixed.

4210-------
4211
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004212- Issue #3612: Added some missing basic types in ctypes.wintypes.
4213
Benjamin Petersone977ad42008-08-20 01:42:01 +00004214- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4215 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4216
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004217- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4218 version reported by these tools does not necessarily follow the python
4219 version numbering scheme, so the module is less strict when parsing it.
4220
Nick Coghlanf70385a2008-08-18 12:42:46 +00004221- Issue #2235: Added Py3k warnings for types which will become unhashable
4222 under the stricter __hash__ inheritance rules in 3.0. Several types
4223 which did not meet the rules for hash invariants and were already
4224 unhashable in 3.0 have now been explicitly flagged as unhashable in
4225 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4226 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4227
Brett Cannon88f801d2008-08-18 00:46:22 +00004228- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4229 imported into the module but exposed as part of the module's API.
4230
Brett Cannon7b96f072008-08-18 00:41:11 +00004231- Remove an unneeded import of abc.ABCMeta from 'inspect'.

4236
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004237- Issue #3575: Incremental decoder's decode function now takes bytearray
4238 by using 's*' instead of 't#'.
4239
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004240- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004241 fails unicode conversion on 2nd parameter. (windows only)
4242
Georg Brandl222e2082010-08-01 22:27:39 +00004243- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004244 in a redirect.
4245
Brett Cannonabe423e2008-08-16 21:47:07 +00004246- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004247 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004248
Facundo Batistaeb90b782008-08-16 14:44:07 +00004249- Issue #2776: fixed small issue when handling an URL with double slash
4250 after a 302 response in the case of not going through a proxy.
4251
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004252- Issue #2676: in the email package, content-type parsing was hanging on
4253 pathological input because of quadratic or exponential behaviour of a
4254 regular expression.
4255
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004256- Issue #3476: binary buffered reading through the new "io" library is now
4257 thread-safe.
4258
Brett Cannonbf3157b2008-08-14 05:00:03 +00004259- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4260 since mimetools itself is deprecated. Because modules are cached, all
4261 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4262

Antoine Pitroude781a42008-08-09 12:43:23 +00004297 asking for a specific length. This problem only affected files opened

4341
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004342- Issue #643841: The language reference now provides more detailed

4354-----------------
4355
Georg Brandl3e483f62008-07-16 22:57:41 +00004356- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4357 its methods now allow for items objects that can be converted to
4358 an integer using operator.index().
4359
Mark Dickinson64b7e502008-07-16 09:40:03 +00004360- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4361 produced a ValueError instead of giving the correct float.
4362
Eric Smitha5fa5a22008-07-16 00:11:49 +00004363- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4364 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4365
Mark Dickinson7103aa42008-07-15 19:08:33 +00004366- Issue #3008: the float type has a new instance method 'float.hex'
4367 and a new class method 'float.fromhex' to convert floating-point
4368 numbers to and from hexadecimal strings, respectively.
4369
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004370- Issue #2235: __hash__ is once again inherited by default. To allow
4371 collections.Hashable to remain meaningful in the presence of the
4372 default hash implementation (object.__hash__), it is now possible
4373 to explicit block inheritance of hash by setting __hash__=None at
4374 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4375 level.
4376
Nick Coghlanb028f502008-07-13 14:52:36 +00004377- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4378 the parent module cannot be found while performing an absolute import.
4379 This means that an incorrectly defined __package__ attribute will
4380 now only prevent relative imports in that module rather than causing
4381 all imports from that module to fail.
4382
Nick Coghlan14ff9942008-07-08 14:21:42 +00004383- Issue #2517: Allow unicode messages in Exceptions again by correctly

4393 another thread's dictionary.
4394
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004395- Issue #3004: Minor change to slice.indices(): the start and stop
4396 arguments are now treated identically, making the behaviour easier
4397 to describe and understand. For example, slice(None, -10,
4398 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4399 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4400 10, -1).
4401
Georg Brandl278fc502008-07-19 12:46:12 +00004402- Issue #3219: Calling a function with repeated keyword arguments,
4403 f(a=2, a=23), would not cause a syntax error. This was a regression
4404 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004406- Issue #2862: Make int and float freelist management consistent with
4407 other freelists. Changes their CompactFreeList apis into

4415 error when they failed.
4416
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004417- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004442- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4443 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004444 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004445 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004461- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4830 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00004831
Vinay Sajip9828b7e2008-06-17 11:04:02 +00004832- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004833 environment to control the '-arch' flags that are used to build
4834 an extension. This was added for compatibility with Apple's build
4835 of Python.
4836
4837- The bundled OSX-specific copy of libbffi is now in sync with the version
4838 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4839
Georg Brandl25c34082008-08-18 23:09:49 +00004840- The threading module gained aliases for names that will be removed in the

4849
Brett Cannonb61d8012008-05-11 23:39:04 +00004850- ``Lib/lib-old`` is now added to sys.path.
4851
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004852- On MacOS X it is now possible to install the framework in 64-bit
4853 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004854 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004855
4856 This is controlled by the configure argument ``--with-universal-archs``:
4857
4858 - ``--with-universal-archs=all``: install 4-way universal
4859
4860 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4861
4862 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4863
4864 This option should be used in combination with ``--enable-universalsdk=``.
4865
4866 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 +00004875
4876- The PyString functions have been renamed to PyBytes. A batch of
4877 defines were added so that the linker still sees the original
4878 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004916- Issue #1631171: Re-implement the 'warnings' module in C (the
4917 original Python code has been kept as backup). This will allow for
4918 using the 'warning's machinery in such places as the parser where
4919 use of pure Python code is not possible. Both the ``showarning()``
4920 and ``formatwarning()`` gain an optional 'line' argument which is
4921 not called by default for backwards-compatibility reasons. Setting
4922 ``warnings.showwarning()`` to an implementation that lacks support
4923 for the ``line`` argument will raise a DeprecationWarning.

4947
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004948- The getpass module has been improved on Unix. It now uses /dev/tty
4949 by default and uses stderr instead of stdout. A GetPassWarning is
4950 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004965- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004966 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004986- Issue #2550: The approach used by client/server code for obtaining
4987 ports to listen on in network-oriented tests has been refined in an
4988 effort to facilitate running multiple instances of the entire
4989 regression test suite in parallel without issue.
4990 test_support.bind_port() has been fixed such that it will always
4991 return a unique port -- which wasn't always the case with the
4992 previous implementation, especially if socket options had been set
4993 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4994 new implementation of bind_port() will actually raise an exception
4995 if it is passed an AF_INET/SOCK_STREAM socket with either the
4996 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4997 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4998 the socket it's been passed. This currently only applies to
4999 Windows. This option prevents any other sockets from binding to the
5000 host/port we've bound to, thus removing the possibility of the
5001 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5002 when a second SOCK_STREAM socket binds and accepts to a host/port
5003 that's already been bound by another socket. The optional preferred
5004 port parameter to bind_port() has been removed. Under no
5005 circumstances should tests be hard coding ports!
5006
5007 test_support.find_unused_port() has also been introduced, which will
5008 pass a temporary socket object to bind_port() in order to obtain an
5009 unused port. The temporary socket object is then closed and
5010 deleted, and the port is returned. This method should only be used
5011 for obtaining an unused port in order to pass to an external program
5012 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5013 a parameter to a server-oriented class that doesn't give you direct
5014 access to the underlying socket used.
5015
5016 Finally, test_support.HOST has been introduced, which should be used
5017 for the host argument of any relevant socket calls (i.e. bind and
5018 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005019
5020 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005022 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5023 test_asynchat and test_socket_ssl.
5024
Georg Brandl3ee81df2008-05-17 18:14:43 +00005025 It is now possible for multiple instances of the regression test
5026 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005305- Added the future_builtins module, which contains hex() and oct().
5306 These are the PEP 3127 version of these functions, designed to be
5307 compatible with the hex() and oct() builtins from Python 3.0. They
5308 differ slightly in their output formats from the existing, unchanged
5309 Python 2.6 builtins. The expected usage of the future_builtins
5310 module is:
5311 from future_builtins import hex, oct
5312
Eric Smith7ef40bf2008-02-20 23:34:22 +00005313- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5314 exponents for exponents with absolute value < 100. Follows C99
5315 standard. This is a change on Windows, which would use 3 digits.
5316 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5317 so that any alterations it does to the resulting string will be
5318 available in stringlib/formatter.h (for float.__format__).
5319
Eric Smith5a3c1352008-02-19 13:21:56 +00005320- Implemented PEP 3101, Advanced String Formatting. This adds a new
5321 builtin format(); a format() method for str and unicode; a
5322 __format__() method to object, str, unicode, int, long, float, and
5323 datetime; the class string.Formatter; and the C API
5324 PyObject_Format().
5325
Georg Brandl3ee81df2008-05-17 18:14:43 +00005326- Fixed several potential crashes, all caused by specially crafted
5327 __del__ methods exploiting objects in temporarily inconsistent
5328 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00005330- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005331 prevent a possible crash: an Abstract Base Class would try to access
5332 a slot on a registered virtual subclass.

5338 in order to allow pymalloc to free more arenas. Python may give back
5339 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005340
Georg Brandl3ee81df2008-05-17 18:14:43 +00005341- Issue #2045: Fix an infinite recursion triggered when printing a
5342 subclass of collections.defaultdict, if its default_factory is set
5343 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005344
Christian Heimesf75dbef2008-02-08 00:11:31 +00005345- Fixed a minor memory leak in dictobject.c. The content of the free
5346 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00005348- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005349 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005350
Georg Brandl3ee81df2008-05-17 18:14:43 +00005351- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5352 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005353 to compact the internal free lists of pre-allocted ints and floats.
5354
Georg Brandl3ee81df2008-05-17 18:14:43 +00005355- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5356 calls. Python expected the return type int but the fork familie
5357 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005358
Georg Brandl3ee81df2008-05-17 18:14:43 +00005359- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5360 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005361
Georg Brandl3ee81df2008-05-17 18:14:43 +00005362- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5363 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005364
Georg Brandl3ee81df2008-05-17 18:14:43 +00005365- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5366 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005368- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5369 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005370
Georg Brandl3ee81df2008-05-17 18:14:43 +00005371- Patch #1473257: generator objects gain a gi_code attribute. This is
5372 the same object as the func_code attribute of the function that
5373 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005374
Georg Brandl3ee81df2008-05-17 18:14:43 +00005375- Issue #1920: "while 0" statements were completely removed by the
5376 compiler, even in the presence of an "else" clause, which is
5377 supposed to be run when the condition is false. Now the compiler
5378 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005379
Guido van Rossumeead05f2008-01-24 18:21:02 +00005380- A few crashers fixed: weakref_in_del.py (issue #1377858);
5381 loosing_dict_ref.py (issue #1303614, test67.py);
5382 borrowed_ref_[34].py (not in tracker).
5383
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005384- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005385 suppressed while an extension is loaded by calling SetErrorMode in
5386 dynload_win.c. The error is still reported properly.
5387
Georg Brandl3ee81df2008-05-17 18:14:43 +00005388- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005389 several extension methods and modules do not work without unicode
5390 support.
5391
Georg Brandl26543b12008-01-21 18:36:51 +00005392- Issue #1882: when compiling code from a string, encoding cookies in the
5393 second line of code were not always recognized correctly.
5394
Georg Brandl14404b62008-01-19 19:27:05 +00005395- Issue #1679: "0x" was taken as a valid integer literal.
5396
Georg Brandl6caad7d2008-01-26 14:19:22 +00005397- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005398 added.
5399
Christian Heimesc94e2b52008-01-14 04:13:37 +00005400- sys.float_info / PyFloat_GetInfo: The floating point information
5401 object was converted from a dict to a specialized structseq object.
5402
Georg Brandl3ee81df2008-05-17 18:14:43 +00005403- Patch #1816: Added sys.flags structseq. It exposes the status of
5404 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005405
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Objects/structseq.c: Implemented new structseq representation. The
5407 patch makes structseqs (e.g. the return value of os.stat) more
5408 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005409
Georg Brandl3ee81df2008-05-17 18:14:43 +00005410- Patch #1700288: added a type attribute cache that caches method
5411 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005412
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005413- Bug #1776: __import__() no longer accepts filenames on any platform.
5414 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005415
Georg Brandlaed6c662008-01-07 17:25:53 +00005416- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5417
Georg Brandl3ee81df2008-05-17 18:14:43 +00005418- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5419 envvar and sys.dont_write_bytecode attribute. All these can be set
5420 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005421
Georg Brandl3ee81df2008-05-17 18:14:43 +00005422- Improve some exception messages when Windows fails to load an
5423 extension module. Now we get for example '%1 is not a valid Win32
5424 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005425
Georg Brandl3ee81df2008-05-17 18:14:43 +00005426- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005428- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5429 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005430
Christian Heimes0a8143f2007-12-18 23:22:54 +00005431- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432 and INF. float("nan"), float("inf") and float("-inf") now work on
5433 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005434
Georg Brandl3ee81df2008-05-17 18:14:43 +00005435- Compiler now generates simpler and faster code for dictionary
5436 literals. The oparg for BUILD_MAP now indicates an estimated
5437 dictionary size. There is a new opcode, STORE_MAP, for adding
5438 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005439
Georg Brandl3ee81df2008-05-17 18:14:43 +00005440- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005448- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005449 SystemError.
5450
Nick Coghlanef01d822007-12-03 12:55:17 +00005451- PEP 366: Allow explicit relative imports when executing modules
5452 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00005467- Patch #1739468: Directories and zipfiles containing a __main__.py
5468 file can now be directly executed by passing their name to the
5469 interpreter. The directory/zipfile is automatically inserted as the
5470 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005471
Georg Brandl3ee81df2008-05-17 18:14:43 +00005472- Issue #1265: Fix a problem with sys.settrace, if the tracing
5473 function uses a generator expression when at the same time the
5474 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005475
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005476- sets and frozensets now have an isdisjoint() method.
5477
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005478- optimize the performance of builtin.sum().
5479
Neal Norwitz44f326e2007-10-05 05:29:17 +00005480- Fix warnings found by the new version of the Coverity checker.
5481
Georg Brandl21e99f42010-03-07 15:23:59 +00005482- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005483 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5484 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005485
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486- Issue #1686386: Tuple's tp_repr did not take into account the
5487 possibility of having a self-referential tuple, which is possible
5488 from C code. Nor did object's tp_str consider that a type's tp_str
5489 could do something that could lead to an inifinite recursion.
5490 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5491 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005492
Georg Brandl3ee81df2008-05-17 18:14:43 +00005493- Issue #1164: It was possible to trigger deadlock when using the
5494 'print' statement to write to a file since the GIL was not released
5495 as needed. Now PyObject_Print() does the right thing along with
5496 various tp_print implementations of the built-in types and those in
5497 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005498
Georg Brandl3ee81df2008-05-17 18:14:43 +00005499- Issue #1147: Exceptions were directly allowing string exceptions in
5500 their throw() method even though string exceptions no longer
5501 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005502
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503- Issue #1096: Prevent a segfault from getting the repr of a very
5504 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005505
Brett Cannon1e534b52007-09-07 04:18:30 +00005506- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005507 PyObject_Call() never calling back out to Python code to trigger
5508 recursion depth updates/checks. Required the creation of a static
5509 RuntimeError instance in case normalizing an exception put the
5510 recursion check value past its limit. Fixes crashers
5511 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005512
Georg Brandl3ee81df2008-05-17 18:14:43 +00005513- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005526- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005527 __*__ attributes. (Some already existed, e.g., __doc__ and
5528 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005529
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005530- Add -3 option to the interpreter to warn about features that are
5531 deprecated and will be changed/removed in Python 3.0.
5532
Georg Brandl2134e752007-05-21 20:34:16 +00005533- Patch #1686487: you can now pass any mapping after '**' in function
5534 calls.
5535
Collin Winter62903052007-05-18 23:11:24 +00005536- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005537 "except E as target:". This is to provide forwards compatibility
5538 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005539
Brett Cannon229cee22007-05-05 01:34:02 +00005540- Deprecate BaseException.message as per PEP 352.
5541
Georg Brandl3ee81df2008-05-17 18:14:43 +00005542- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005543 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005544
Vinay Sajip8549ce32007-05-06 17:53:37 +00005545- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005546 setting a plain string, ie don't expand to single letter identifiers.
5547
Raymond Hettinger13936692007-04-11 18:40:58 +00005548- Request #1191699: Slices can now be pickled.
5549
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005550- Request #1193128: str.translate() now allows a None argument for
5551 translations that only remove characters without re-mapping the
5552 remaining characters.
5553
Georg Brandl5cb76c12007-03-21 09:00:39 +00005554- Patch #1682205: a TypeError while unpacking an iterable is no longer
5555 masked by a generic one with the message "unpack non-sequence".
5556
Neal Norwitzaa754b72007-03-21 06:39:48 +00005557- Remove unused file Python/fmod.c.
5558
Guido van Rossum143b5642007-03-23 04:58:42 +00005559- Bug #1683368: The object.__init__() and object.__new__() methods are
5560 now stricter in rejecting excess arguments. The only time when
5561 either allows excess arguments is when it is not overridden and the
5562 other one is. For backwards compatibility, when both are
5563 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005564 warning later). Also, type.__init__() insists on the same signature
5565 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005566
Georg Brandl3ee81df2008-05-17 18:14:43 +00005567- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5568 object to complex using its __complex__() method before falling back
5569 to the __float__() method. Therefore, the functions in the cmath
5570 module now can operate on objects that define a __complex__()
5571 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006645 time so that opening a database previously created with the DB_DUP
6646 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6647 opens. Specifically: dictionary assignment to a DB object will
6648 replace all values for a given key when the database allows
6649 duplicate values. DB users should use DB.put(k, v) when they want
6650 to store duplicates; not DB[k] = v.

6657 characters with ASCII value less than 32. Also, it correctly quotes
6658 dots only if they occur on a single line, as opposed to the previous
6659 behavior of quoting dots if they are the second character of any
6660 line.
