Nadeem Vawda6cad3712012-11-05 00:55:06 +0100297 successive calls after EOF in unused_data, instead of only saving the argument
Nadeem Vawda252f4dc2012-11-11 02:14:15 +0100298 to the last call. decompressobj().flush() now correctly sets unused_data and
299 unconsumed_tail. A bug in the handling of MemoryError when setting the

936 distutils.sysconfig and another copy in distutils.ccompiler, with some

939 is the case in 3.x.
940
Ned Deily0d0ea482012-02-10 12:59:06 +0100941- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
942 Distutils-based packages with C extension modules may fail because
943 Apple has removed gcc-4.2, the version used to build python.org
944 64-bit/32-bit Pythons. If the user does not explicitly override
945 the default C compiler by setting the CC environment variable,
946 Distutils will now attempt to compile extension modules with clang
947 if gcc-4.2 is required but not found. Also as a convenience, if
948 the user does explicitly set CC, substitute its value as the default
949 compiler in the Distutils LDSHARED configuration variable for OS X.
950 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
951 SDK, neither of which are available in Xcode 4. This change does not
952 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001225- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1226 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1227 interpreter process. This could cause failures in non-Distutils subprocesses
1228 and was unreliable since tests or user programs could modify the interpreter
1229 environment after Distutils set it. Instead, have Distutils set the the
1230 deployment target only in the environment of each build subprocess. It is
1231 still possible to globally override the default by setting
1232 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1233 greater or equal to the default value, the value with which the interpreter
1234 was built.

1264 the ticker doesn't have to wind down to zero from the old starting point
1265 before the new interval takes effect. And if the user increases the
1266 interval, it makes sure the new limit takes effect right away rather have an
1267 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00002063- Issue #9869: Make long() and PyNumber_Long return something of type
2064 long for a class whose __long__ method returns a plain int. This
2065 fixes an interpreter crash when initializing an instance of a long

Antoine Pitrou0a7b65b2010-09-08 12:40:49 +00002070- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2071 thread-local storage key.
2072
Victor Stinnercaafd772010-09-08 10:51:01 +00002073- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2074 encoding and errors attributes instead of using utf-8 in strict mode, to get
2075 the same behaviour than the print statement.
2076
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002077- Issue #9737: Fix a crash when trying to delete a slice or an item from
2078 a memoryview object.

2091
2092 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2093 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
2094

2189 received. Now sendall() properly calls signal handlers if necessary,

2202 handles non-blocking readinto() returning None correctly.
2203

2205 SSLSocket.sendto() to match the corresponding socket methods. Also,
2206 fix various SSLSocket methods to raise socket.error rather than an
2207 unhelpful TypeError when called on an unconnected socket. Original patch
2208 by Andrew Bennetts.
2209
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002210- Issue #9826: OrderedDict.__repr__ can now handle self-referential
2211 values: d['x'] = d.
2212
Victor Stinner8fc843b2010-09-17 23:35:50 +00002213- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

Antoine Pitroue4195e82010-09-12 14:56:27 +00002215- Issue #9837: The read() method of ZipExtFile objects (as returned by

2217
Raymond Hettinger20397532010-09-12 02:11:45 +00002218- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2219 This prevents user-created self-referencing ordered dictionaries from
2220 becoming permanently uncollectable GC garbage. The downside is that
2221 removing __del__ means that the internal doubly-linked list has to wait for
2222 GC collection rather than freeing memory immediately when the refcnt drops
2223 to zero.
2224
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002225- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002226 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002227 value.
2228
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002229- Issue #9792: In case of connection failure, socket.create_connection()
2230 would swallow the exception and raise a new one, making it impossible
2231 to fetch the original errno, or to filter timeout errors. Now the
2232 original error is re-raised.
2233
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002234- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2235 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2236 be updated back after the system call. Original patch by Brian Brazil.
2237
Antoine Pitroudca9de92010-09-04 17:52:26 +00002238- Issue #1100562: Fix deep-copying of objects derived from the list and

2242 ConfigParser.write.
2243
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002244- Issue #808164: Fixed socket.close to avoid references to globals, to
2245 avoid issues when socket.close is called from a __del__ method.
2246
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002247- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
2248 can be set to False to turn off the previously undocumented 'popularity'
2249 heuristic. Patch by Terry Reedy and Eli Bendersky
2250
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002251- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2252 falling into recursion.
2253
R. David Murray7c4bf552010-08-25 01:45:57 +00002254- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2255 character years even if the message contains RFC822 two character years.
2256
Daniel Stutzbach91287322010-08-24 21:09:30 +00002257- Issue #8750: Fixed MutableSet's methods to correctly handle
2258 reflexive operations, namely x -= x and x ^= x.
2259

2267
Raymond Hettinger917bba12010-08-22 08:01:58 +00002268- Issue #9214: Set operations on KeysView or ItemsView in the collections
2269 module now correctly return a set. (Patch by Eli Bendersky.)
2270
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002271- Issue #9617: Signals received during a low-level write operation aren't
2272 ignored by the buffered IO layer anymore.
2273
Benjamin Peterson52c36052010-08-21 03:03:22 +00002274- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2275 are not held onto after they are deleted elsewhere.
2276
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002277- Issue #9626: the view methods for collections.OrderedDict() were returning
2278 the unordered versions inherited from dict. Those methods are now
2279 overridden to provide ordered views.
2280
Éric Araujo0389ae62010-08-14 03:07:46 +00002281- Issue #8688: MANIFEST files created by distutils now include a magic
2282 comment indicating they are generated. Manually maintained MANIFESTs
2283 without this marker will not be overwritten or removed.
2284
Antoine Pitroue1436d12010-08-12 15:25:51 +00002285- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2286 and a BadZipfile error is raised if it doesn't match (as used to be the
2287 case in Python 2.5 and earlier).
2288
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002289- Issue #9550: a BufferedReader could issue an additional read when the
2290 original read request had been satisfied, which could block indefinitely
2291 when the underlying raw IO channel was e.g. a socket. Report and original
2292 patch by Jason V. Miller.
2293
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002294- Issue #9551: Don't raise TypeError when setting the value to None for

2310 PROT_WRITE and PROT_EXEC.
2311
Senthil Kumarane677ecf2010-08-08 11:56:31 +00002312- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2313 This is how it is supposed to work, wget and curl do the same. Previous
2314 behavior was wrong.
2315

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002682- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2683 start byte and the continuation byte(s) are now considered invalid, instead
2684 of the number of bytes specified by the start byte.
2685 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2686 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2687 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2688 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002696- Issue #8748: Fix two issues with comparisons between complex and integer
2697 objects. (1) The comparison could incorrectly return True in some cases
2698 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2699 (2) The comparison raised an OverflowError for large integers, leading
2700 to unpredictable exceptions when combining integers and complex objects
2701 in sets or dicts.

3084 with a non-empty format string. This is an effort to future-proof user
3085 code. If a derived class does not currently implement __format__ but later
3086 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003087 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003088 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003121- Issue #8257: The Decimal construct now accepts a float instance directly,
3122 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003123
3124 >>> Decimal(1.1)
3125 Decimal('1.100000000000000088817841970012523233890533447265625')
3126

Georg Brandlfee0f442010-05-22 21:26:21 +00003138- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3139 InvalidOperation instead of returning False. (Comparisons involving a quiet
3140 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3141 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003142
Georg Brandlfee0f442010-05-22 21:26:21 +00003143- Issue #2531: Comparison operations between floats and Decimal instances now
3144 return a result based on the numeric values of the operands; previously they
3145 returned an arbitrary result based on the relative ordering of id(float) and
3146 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003147
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003148- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003149 argument `-` which tells it to read files to compile from stdin. Each line is
3150 read on demand and the named file is compiled immediately. (Original patch by
3151 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003152
Georg Brandlfee0f442010-05-22 21:26:21 +00003153- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Georg Brandlfee0f442010-05-22 21:26:21 +00003160- Comparisons using one of <, <=, >, >= between a complex instance and a
3161 Fractions instance now raise TypeError instead of returning True/False. This
3162 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3163 <=> complex, and complex <=> complex comparisons.

3232 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3233 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003262- Issue #8300: When passing a non-integer argument to struct.pack with any
3263 integer format code, struct.pack first attempts to convert the non-integer

3265 TypeError it goes on to try the __int__ method, as described below.
3266
Georg Brandlba83f822010-03-14 09:50:54 +00003267- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3268 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3269 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003270 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3271 inconsistent: __int__ was used for some integer codes but not for others, and
3272 the set of integer codes for which it was used differed between native packing
3273 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003580- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003581 file position when calling `truncate()`. It would previously change the file
3582 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003583 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00003585- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3586 class used to represent files stored inside an archive. The new
3587 implementation is significantly faster and can be wrapped in a
3588 ``io.BufferedReader`` object for more speedups. It also solves an issue
3589 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003680- The ``__complex__()`` method is now looked up on the class of instances to
3681 make it consistent with other special methods.

3685
Mark Dickinson1b34d252010-01-01 17:27:30 +00003686- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003687 DeprecationWarning when passed a float argument where an integer was expected.
3688 These functions and methods now raise TypeError instead. The majority of the
3689 effects of this change are in the extension modules, but some core functions
3690 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3691 and many unicode/str methods.

3706 least on IEEE 754 platforms), and in particular does not depend on the
3707 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003856- Issue #3382: 'F' formatting for float and complex now convert the result to
3857 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3858 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003859
Georg Brandlba83f822010-03-14 09:50:54 +00003860- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3861 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003862
Georg Brandlba83f822010-03-14 09:50:54 +00003863- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3864 1e-100 used to raise OverflowError, but now gives the requested 120
3865 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00003866

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003873
Georg Brandlba83f822010-03-14 09:50:54 +00003874- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3875 decimal string that's guaranteed to round back to x under correct rounding
3876 (with round-half-to-even rounding mode). Previously it gave a string based on
3877 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3878 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3879 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003880
Georg Brandlba83f822010-03-14 09:50:54 +00003881- Issue #7117: On almost all platforms: float-to-string and string-to-float
3882 conversions within Python are now correctly rounded. Places these conversions
3883 occur include: str for floats and complex numbers; the float and complex
3884 constructors; old-style and new-style numeric formatting; serialization and
3885 deserialization of floats and complex numbers using marshal, pickle and json;
3886 parsing of float and imaginary literals in Python code; Decimal-to-float
3887 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003888
Georg Brandlba83f822010-03-14 09:50:54 +00003889 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3890 providing correctly-rounded strtod and dtoa C functions. This code is
3891 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3892 the C compiler. There may be a small number of platforms on which correct
3893 operation of this code cannot be guaranteed, so the code is not used: notably,
3894 this applies to platforms where the C double format is not IEEE 754 binary64,
3895 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3896 and Python's configure script is unable to determine how to change the FPU
3897 precision. On these platforms conversions use the platform strtod and dtoa,
3898 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003899
Georg Brandlba83f822010-03-14 09:50:54 +00003900- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3901 uses the correctly-rounded string <-> float conversions described above (when
3902 available), and so produces correctly rounded results that will display nicely
3903 under the float repr. There are two related small changes: (1) round now
3904 accepts any class with an ``__index__()`` method for its second argument (but
3905 no longer accepts floats for the second argument), and (2) an excessively
3906 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3907 raises an exception.

3910
Georg Brandlba83f822010-03-14 09:50:54 +00003911- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00004050 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4051 (2) parsing of strings representing infinities and nans was locale aware; and
4052 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004054- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4055 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4056 but with at least one decimal point and with a default precision
4057 of 12. Previously, the behavior the same but with a default precision of 6.
4058 This more closely matches ``str()``, and reduces surprises when adding
4059 alignment flags to the empty presentation type. This also affects the new
4060 complex.__format__ in the same way.
4061
4062- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4063 classtype's, even if it was None. property now inserts the __doc__ into the
4064 subclass instance __dict__.

4291 eventual KeyError would always report the empty ``frozenset()`` as the missing

Georg Brandlba83f822010-03-14 09:50:54 +00005546 leak-chasing test runs give sensible results. The previous method of reaping
5547 threads could return successfully while some Thread objects were still
5548 referenced. This also introduces a new private function: ``thread._count()``.

5687
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005688- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5689
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005690- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5691 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5692 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5693 ``printf`` function, whereas PyString_FromFormat has an independent
5694 implementation and uses "%zd" on all platforms for size_t values.
5695 This makes a difference on win64, where ``printf`` needs "%Id" to display
5696 64bit values.
5697
Benjamin Peterson97179b02008-09-09 20:55:01 +00005698- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5699 error.
5700
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005701- Issue #3777: long() applied to a float object now always return a long
5702 object; previously an int would be returned for small values. the __long__
5703 method is allowed to return either an int or a long, but the behaviour of
5704 float objects should not change to respect backward compatibility.
5705
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005706- Issue #3751: str.rpartition would perform a left-partition when called with
5707 a unicode argument.
5708
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005709- Issue #3683: Fix compilation when --without-threads is given.
5710
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005711- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005712 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005713 was correctly parsed but parsing of subsequent arguments failed.
5714
Vinay Sajip35e3b032008-09-01 14:33:59 +00005715- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005716 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5717 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5718 when given a tuple of classes as second argument, were looking up
5719 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5720 type object.
5721
Neal Norwitz18aa3882008-08-24 05:04:52 +00005722- Fix crashes on memory allocation failure found with failmalloc.
5723
5724- Fix memory leaks found with valgrind and update suppressions file.
5725
5726- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5727
5728- Fix problem using wrong name in decimal module reported by pychecker.
5729
Christian Heimes7d4c3172008-08-22 19:47:25 +00005730- Silenced another compiler warning about a used but not defined
5731 function 'stringlib_contains_obj'.
5732
Benjamin Peterson712ee922008-08-24 18:10:20 +00005733- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5734 ``__delslice__``.
5735
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005736- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5737 library targets in the Makefile.
5738
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005739- Issue #1204: The configure script now tests for additional libraries
5740 that may be required when linking against readline. This fixes issues
5741 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00005765 return a list or None rather than a custom object.
5766
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005767- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005791 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5792 for catch_warnings() also led to an improvement in the raising of a
5793 DeprecationWarning related to warnings.warn_explicit().
5794
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005795- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005859What's New in Python 2.6 beta 3?
5860================================
5861
Barry Warsaw07a4a382008-08-21 01:15:08 +00005862*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005863
5864Core and Builtins
5865-----------------
5866
Guido van Rossumf8402962008-08-20 15:01:50 +00005867- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5868 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5869 extensions do not automatically benefit from the class attribute
5870 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5871 to their tp_flags field if they care. This is a backwards
5872 compatibility feature; in 3.0, all types will use the cache by
5873 default.
5874
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005875- Keyword arguments can now follow starred arguments. (``f(a, *args,
5876 keyword=23)`` is now valid syntax.)
5877
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005878- ctypes function pointers that are COM methods have a boolean True
5879 value again.
5880
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005881- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5882 by denying s# to parse objects that have a releasebuffer procedure,
5883 and introducing s*.
5884
Georg Brandl1e13ea92008-08-11 09:07:59 +00005885- Issue #3537: Fix an assertion failure when an empty but presized dict
5886 object was stored in the freelist.
5887
Mark Dickinsonb6467572008-08-04 21:30:09 +00005888- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5889 ValueError consistently across platforms.
5890
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005891- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5892 (64bit Unix, for example), unichr() would truncate its argument and return
5893 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5894
Neal Norwitze7d8be82008-07-31 17:17:14 +00005895- Apply security patches from Apple.
5896
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005897- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5898 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5899
Antoine Pitrou92f82162008-07-25 22:22:08 +00005900- Issue #1819: function calls with several named parameters are now on
5901 average 35% faster (as measured by pybench).
5902
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005903- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5904 the python debugger steps into a class statement: the free variables (local
5905 variables defined in an outer scope) would be deleted from the outer scope.
5906
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005907- Issue #2620: Overflow checking when allocating or reallocating memory
5908 was not always being done properly in some python types and extension
5909 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5910 all been updated to perform better checks and places in the code that
5911 would previously leak memory on the error path when such an allocation
5912 failed have been fixed.

5918
Benjamin Petersone977ad42008-08-20 01:42:01 +00005919- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5920 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5921
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005922- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5923 version reported by these tools does not necessarily follow the python
5924 version numbering scheme, so the module is less strict when parsing it.
5925
Nick Coghlanf70385a2008-08-18 12:42:46 +00005926- Issue #2235: Added Py3k warnings for types which will become unhashable
5927 under the stricter __hash__ inheritance rules in 3.0. Several types
5928 which did not meet the rules for hash invariants and were already
5929 unhashable in 3.0 have now been explicitly flagged as unhashable in
5930 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5931 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5932
Brett Cannon88f801d2008-08-18 00:46:22 +00005933- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005940- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5941
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005942- Issue #3575: Incremental decoder's decode function now takes bytearray
5943 by using 's*' instead of 't#'.
5944
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005945- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005946 fails unicode conversion on 2nd parameter. (windows only)
5947
Georg Brandl222e2082010-08-01 22:27:39 +00005948- Issue #2464: urllib2 now supports a malformation in the URL received

Antoine Pitroude781a42008-08-09 12:43:23 +00006002 asking for a specific length. This problem only affected files opened

6046
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006047- Issue #643841: The language reference now provides more detailed

6060
Georg Brandl3e483f62008-07-16 22:57:41 +00006061- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6062 its methods now allow for items objects that can be converted to
6063 an integer using operator.index().
6064
Mark Dickinson64b7e502008-07-16 09:40:03 +00006065- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6066 produced a ValueError instead of giving the correct float.
6067
Eric Smitha5fa5a22008-07-16 00:11:49 +00006068- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6069 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6070
Mark Dickinson7103aa42008-07-15 19:08:33 +00006071- Issue #3008: the float type has a new instance method 'float.hex'
6072 and a new class method 'float.fromhex' to convert floating-point
6073 numbers to and from hexadecimal strings, respectively.
6074
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006075- Issue #2235: __hash__ is once again inherited by default. To allow
6076 collections.Hashable to remain meaningful in the presence of the
6077 default hash implementation (object.__hash__), it is now possible
6078 to explicit block inheritance of hash by setting __hash__=None at
6079 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6080 level.
6081
Nick Coghlanb028f502008-07-13 14:52:36 +00006082- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6083 the parent module cannot be found while performing an absolute import.
6084 This means that an incorrectly defined __package__ attribute will
6085 now only prevent relative imports in that module rather than causing
6086 all imports from that module to fail.
6087
Nick Coghlan14ff9942008-07-08 14:21:42 +00006088- Issue #2517: Allow unicode messages in Exceptions again by correctly

6098 another thread's dictionary.
6099
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006100- Issue #3004: Minor change to slice.indices(): the start and stop
6101 arguments are now treated identically, making the behaviour easier
6102 to describe and understand. For example, slice(None, -10,
6103 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6104 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6105 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00006107- Issue #3219: Calling a function with repeated keyword arguments,
6108 f(a=2, a=23), would not cause a syntax error. This was a regression
6109 from 2.4 caused by the switch to the new compiler.

6148 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006149 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006150 content-length. The problem had been corrected in the 2.4 branch, but never

6556
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006557- On MacOS X it is now possible to install the framework in 64-bit
6558 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006559 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006560
6561 This is controlled by the configure argument ``--with-universal-archs``:
6562
6563 - ``--with-universal-archs=all``: install 4-way universal
6564
6565 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6566
6567 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6568
6569 This option should be used in combination with ``--enable-universalsdk=``.
6570
6571 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006621- Issue #1631171: Re-implement the 'warnings' module in C (the
6622 original Python code has been kept as backup). This will allow for
6623 using the 'warning's machinery in such places as the parser where
6624 use of pure Python code is not possible. Both the ``showarning()``
6625 and ``formatwarning()`` gain an optional 'line' argument which is
6626 not called by default for backwards-compatibility reasons. Setting
6627 ``warnings.showwarning()`` to an implementation that lacks support
6628 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006653- The getpass module has been improved on Unix. It now uses /dev/tty
6654 by default and uses stderr instead of stdout. A GetPassWarning is
6655 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006670- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006671 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006691- Issue #2550: The approach used by client/server code for obtaining
6692 ports to listen on in network-oriented tests has been refined in an
6693 effort to facilitate running multiple instances of the entire
6694 regression test suite in parallel without issue.
6695 test_support.bind_port() has been fixed such that it will always
6696 return a unique port -- which wasn't always the case with the
6697 previous implementation, especially if socket options had been set
6698 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6699 new implementation of bind_port() will actually raise an exception
6700 if it is passed an AF_INET/SOCK_STREAM socket with either the
6701 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6702 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6703 the socket it's been passed. This currently only applies to
6704 Windows. This option prevents any other sockets from binding to the
6705 host/port we've bound to, thus removing the possibility of the
6706 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6707 when a second SOCK_STREAM socket binds and accepts to a host/port
6708 that's already been bound by another socket. The optional preferred
6709 port parameter to bind_port() has been removed. Under no
6710 circumstances should tests be hard coding ports!
6711
6712 test_support.find_unused_port() has also been introduced, which will
6713 pass a temporary socket object to bind_port() in order to obtain an
6714 unused port. The temporary socket object is then closed and
6715 deleted, and the port is returned. This method should only be used
6716 for obtaining an unused port in order to pass to an external program
6717 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6718 a parameter to a server-oriented class that doesn't give you direct
6719 access to the underlying socket used.
6720
6721 Finally, test_support.HOST has been introduced, which should be used
6722 for the host argument of any relevant socket calls (i.e. bind and
6723 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006724
6725 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006726 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006727 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6728 test_asynchat and test_socket_ssl.
6729
Georg Brandl3ee81df2008-05-17 18:14:43 +00006730 It is now possible for multiple instances of the regression test
6731 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007010- Added the future_builtins module, which contains hex() and oct().
7011 These are the PEP 3127 version of these functions, designed to be
7012 compatible with the hex() and oct() builtins from Python 3.0. They
7013 differ slightly in their output formats from the existing, unchanged
7014 Python 2.6 builtins. The expected usage of the future_builtins
7015 module is:
7016 from future_builtins import hex, oct
7017
Eric Smith7ef40bf2008-02-20 23:34:22 +00007018- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7019 exponents for exponents with absolute value < 100. Follows C99
7020 standard. This is a change on Windows, which would use 3 digits.
7021 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7022 so that any alterations it does to the resulting string will be
7023 available in stringlib/formatter.h (for float.__format__).
7024
Eric Smith5a3c1352008-02-19 13:21:56 +00007025- Implemented PEP 3101, Advanced String Formatting. This adds a new
7026 builtin format(); a format() method for str and unicode; a
7027 __format__() method to object, str, unicode, int, long, float, and
7028 datetime; the class string.Formatter; and the C API
7029 PyObject_Format().
7030
Georg Brandl3ee81df2008-05-17 18:14:43 +00007031- Fixed several potential crashes, all caused by specially crafted
7032 __del__ methods exploiting objects in temporarily inconsistent
7033 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007039- Fixed repr() and str() of complex numbers with infinity or nan as
7040 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007041
Georg Brandl3ee81df2008-05-17 18:14:43 +00007042- Clear all free lists during a gc.collect() of the highest generation
7043 in order to allow pymalloc to free more arenas. Python may give back
7044 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007045
Georg Brandl3ee81df2008-05-17 18:14:43 +00007046- Issue #2045: Fix an infinite recursion triggered when printing a
7047 subclass of collections.defaultdict, if its default_factory is set
7048 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007049
Christian Heimesf75dbef2008-02-08 00:11:31 +00007050- Fixed a minor memory leak in dictobject.c. The content of the free
7051 list was not freed on interpreter shutdown.
7052
Georg Brandl21e99f42010-03-07 15:23:59 +00007053- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007054 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007055
Georg Brandl3ee81df2008-05-17 18:14:43 +00007056- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7057 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007058 to compact the internal free lists of pre-allocted ints and floats.
7059
Georg Brandl3ee81df2008-05-17 18:14:43 +00007060- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7061 calls. Python expected the return type int but the fork familie
7062 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007063
Georg Brandl3ee81df2008-05-17 18:14:43 +00007064- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7065 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007066

Georg Brandl3ee81df2008-05-17 18:14:43 +00007076- Patch #1473257: generator objects gain a gi_code attribute. This is
7077 the same object as the func_code attribute of the function that
7078 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007079
Georg Brandl3ee81df2008-05-17 18:14:43 +00007080- Issue #1920: "while 0" statements were completely removed by the
7081 compiler, even in the presence of an "else" clause, which is
7082 supposed to be run when the condition is false. Now the compiler
7083 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007084
Guido van Rossumeead05f2008-01-24 18:21:02 +00007085- A few crashers fixed: weakref_in_del.py (issue #1377858);
7086 loosing_dict_ref.py (issue #1303614, test67.py);
7087 borrowed_ref_[34].py (not in tracker).
7088
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007089- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007090 suppressed while an extension is loaded by calling SetErrorMode in
7091 dynload_win.c. The error is still reported properly.
7092
Georg Brandl3ee81df2008-05-17 18:14:43 +00007093- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007094 several extension methods and modules do not work without unicode
7095 support.
7096
Georg Brandl26543b12008-01-21 18:36:51 +00007097- Issue #1882: when compiling code from a string, encoding cookies in the

7099
Georg Brandl14404b62008-01-19 19:27:05 +00007100- Issue #1679: "0x" was taken as a valid integer literal.
7101
Georg Brandl6caad7d2008-01-26 14:19:22 +00007102- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007103 added.
7104
Christian Heimesc94e2b52008-01-14 04:13:37 +00007105- sys.float_info / PyFloat_GetInfo: The floating point information
7106 object was converted from a dict to a specialized structseq object.
7107
Georg Brandl3ee81df2008-05-17 18:14:43 +00007108- Patch #1816: Added sys.flags structseq. It exposes the status of
7109 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007110
Georg Brandl3ee81df2008-05-17 18:14:43 +00007111- Objects/structseq.c: Implemented new structseq representation. The
7112 patch makes structseqs (e.g. the return value of os.stat) more
7113 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007114
Georg Brandl3ee81df2008-05-17 18:14:43 +00007115- Patch #1700288: added a type attribute cache that caches method
7116 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007117
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007118- Bug #1776: __import__() no longer accepts filenames on any platform.
7119 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007120
Georg Brandlaed6c662008-01-07 17:25:53 +00007121- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7122
Georg Brandl3ee81df2008-05-17 18:14:43 +00007123- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7124 envvar and sys.dont_write_bytecode attribute. All these can be set
7125 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007126
Georg Brandl3ee81df2008-05-17 18:14:43 +00007127- Improve some exception messages when Windows fails to load an
7128 extension module. Now we get for example '%1 is not a valid Win32
7129 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007130

7134 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007135
Christian Heimes0a8143f2007-12-18 23:22:54 +00007136- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007137 and INF. float("nan"), float("inf") and float("-inf") now work on
7138 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007139
Georg Brandl3ee81df2008-05-17 18:14:43 +00007140- Compiler now generates simpler and faster code for dictionary
7141 literals. The oparg for BUILD_MAP now indicates an estimated
7142 dictionary size. There is a new opcode, STORE_MAP, for adding
7143 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007172- Patch #1739468: Directories and zipfiles containing a __main__.py
7173 file can now be directly executed by passing their name to the
7174 interpreter. The directory/zipfile is automatically inserted as the
7175 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007176
Georg Brandl3ee81df2008-05-17 18:14:43 +00007177- Issue #1265: Fix a problem with sys.settrace, if the tracing
7178 function uses a generator expression when at the same time the
7179 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007180
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007181- sets and frozensets now have an isdisjoint() method.
7182
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007183- optimize the performance of builtin.sum().
7184
Neal Norwitz44f326e2007-10-05 05:29:17 +00007185- Fix warnings found by the new version of the Coverity checker.
7186
Georg Brandl21e99f42010-03-07 15:23:59 +00007187- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007188 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7189 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007190
Georg Brandl3ee81df2008-05-17 18:14:43 +00007191- Issue #1686386: Tuple's tp_repr did not take into account the
7192 possibility of having a self-referential tuple, which is possible
7193 from C code. Nor did object's tp_str consider that a type's tp_str
7194 could do something that could lead to an inifinite recursion.
7195 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7196 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007197
Georg Brandl3ee81df2008-05-17 18:14:43 +00007198- Issue #1164: It was possible to trigger deadlock when using the
7199 'print' statement to write to a file since the GIL was not released
7200 as needed. Now PyObject_Print() does the right thing along with
7201 various tp_print implementations of the built-in types and those in
7202 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007203
Georg Brandl3ee81df2008-05-17 18:14:43 +00007204- Issue #1147: Exceptions were directly allowing string exceptions in
7205 their throw() method even though string exceptions no longer
7206 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007207
Georg Brandl3ee81df2008-05-17 18:14:43 +00007208- Issue #1096: Prevent a segfault from getting the repr of a very
7209 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007210
Brett Cannon1e534b52007-09-07 04:18:30 +00007211- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007212 PyObject_Call() never calling back out to Python code to trigger
7213 recursion depth updates/checks. Required the creation of a static
7214 RuntimeError instance in case normalizing an exception put the
7215 recursion check value past its limit. Fixes crashers
7216 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007217

Neal Norwitz0ac60192007-05-27 04:08:54 +00007231- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007232 __*__ attributes. (Some already existed, e.g., __doc__ and
7233 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007234
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007235- Add -3 option to the interpreter to warn about features that are
7236 deprecated and will be changed/removed in Python 3.0.
7237
Georg Brandl2134e752007-05-21 20:34:16 +00007238- Patch #1686487: you can now pass any mapping after '**' in function
7239 calls.
7240
Collin Winter62903052007-05-18 23:11:24 +00007241- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007242 "except E as target:". This is to provide forwards compatibility
7243 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007245- Deprecate BaseException.message as per PEP 352.
7246
Georg Brandl3ee81df2008-05-17 18:14:43 +00007247- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007248 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007249
Vinay Sajip8549ce32007-05-06 17:53:37 +00007250- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007251 setting a plain string, ie don't expand to single letter identifiers.
7252
Raymond Hettinger13936692007-04-11 18:40:58 +00007253- Request #1191699: Slices can now be pickled.
7254
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007255- Request #1193128: str.translate() now allows a None argument for
7256 translations that only remove characters without re-mapping the
7257 remaining characters.
7258
Georg Brandl5cb76c12007-03-21 09:00:39 +00007259- Patch #1682205: a TypeError while unpacking an iterable is no longer
7260 masked by a generic one with the message "unpack non-sequence".
7261
Neal Norwitzaa754b72007-03-21 06:39:48 +00007262- Remove unused file Python/fmod.c.
7263
Guido van Rossum143b5642007-03-23 04:58:42 +00007264- Bug #1683368: The object.__init__() and object.__new__() methods are
7265 now stricter in rejecting excess arguments. The only time when
7266 either allows excess arguments is when it is not overridden and the
7267 other one is. For backwards compatibility, when both are
7268 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007269 warning later). Also, type.__init__() insists on the same signature
7270 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007272- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7273 object to complex using its __complex__() method before falling back
7274 to the __float__() method. Therefore, the functions in the cmath
7275 module now can operate on objects that define a __complex__()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007433 generator expressions (x for x, in ... ) works again. Fixing this
7434 problem required changing the .pyc magic number. This means that

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008248 that the SMTP.starttls() caller no longer needs to call ehlo()
8249 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008250 does not claim to support starttls. Adds the
8251 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8252 Fenner.

8332 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8333 silently miscode subclasses of those types. Now, it raises a
8334 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008335

Georg Brandl3ee81df2008-05-17 18:14:43 +00008350 time so that opening a database previously created with the DB_DUP
8351 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8352 opens. Specifically: dictionary assignment to a DB object will
8353 replace all values for a given key when the database allows
8354 duplicate values. DB users should use DB.put(k, v) when they want
8355 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008356

8362 characters with ASCII value less than 32. Also, it correctly quotes
8363 dots only if they occur on a single line, as opposed to the previous
8364 behavior of quoting dots if they are the second character of any
8365 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008366
