553
554- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
555 and later systems as is currently done for Python 3.x installers.
556 For 2.7.7 only, we will provide three installers:
557 the legacy deprecated 10.3+ 32-bit-only format;
558 the newer 10.5+ 32-bit-only format;
559 and the unchanged 10.6+ 64-/32-bit format.
560 Although binary installers will no longer be available from
561 python.org as of 2.7.8, it will still be possible to build from
562 source on 10.3.9 and 10.4 systems if necessary.
563 See Mac/BuildScript/README.txt for more information.

1942 32-bit-only installer Pythons on systems with Xcode 4 (currently
1943 OS X 10.8, 10.7, and optionally 10.6).
1944 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1945 * Since Xcode 4 removes ppc support, extension module builds now
1946 check for ppc compiler support and by default remove ppc and
1947 ppc64 archs when they are not available.
1948 * Extension module builds now revert to using system installed
1949 headers and libs (/usr and /System/Library) if the SDK used
1950 to build the interpreter is not installed or has moved.
1951 * Try to avoid building extension modules with deprecated
1952 and problematic Apple llvm-gcc compiler. If original compiler
1953 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002377- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002378 has left two versions of customize_compiler, the original in
2379 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002384- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2385 Distutils-based packages with C extension modules may fail because
2386 Apple has removed gcc-4.2, the version used to build python.org
2387 64-bit/32-bit Pythons. If the user does not explicitly override
2388 the default C compiler by setting the CC environment variable,
2389 Distutils will now attempt to compile extension modules with clang
2390 if gcc-4.2 is required but not found. Also as a convenience, if
2391 the user does explicitly set CC, substitute its value as the default
2392 compiler in the Distutils LDSHARED configuration variable for OS X.
2393 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2394 SDK, neither of which are available in Xcode 4. This change does not
2395 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002645- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2646 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2647 interpreter process. This could cause failures in non-Distutils subprocesses
2648 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002649 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002650 deployment target only in the environment of each build subprocess. It is
2651 still possible to globally override the default by setting
2652 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2653 greater or equal to the default value, the value with which the interpreter
2654 was built.

2683 updating the check interval, so if the user decreases the check interval,
2684 the ticker doesn't have to wind down to zero from the old starting point
2685 before the new interval takes effect. And if the user increases the
2686 interval, it makes sure the new limit takes effect right away rather have an
2687 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00003512- Issue #9869: Make long() and PyNumber_Long return something of type
3513 long for a class whose __long__ method returns a plain int. This
3514 fixes an interpreter crash when initializing an instance of a long
3515 subclass from an object whose __long__ method returns a plain int.

Benjamin Petersona5d5cc42010-10-02 00:08:58 +00003517- Issue #10006: type.__abstractmethods__ now raises an AttributeError.

Antoine Pitrou0a7b65b2010-09-08 12:40:49 +00003519- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3520 thread-local storage key.
3521
Victor Stinnercaafd772010-09-08 10:51:01 +00003522- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
3523 encoding and errors attributes instead of using utf-8 in strict mode, to get
3524 the same behaviour than the print statement.
3525
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00003526- Issue #9737: Fix a crash when trying to delete a slice or an item from
3527 a memoryview object.
3528
Martin v. Löwis6086b0d2010-08-19 09:09:04 +00003529- Restore GIL in nis_cat in case of error.

3539 output with no type specifier failed to match the str output:
3540
3541 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3542 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
3543
Antoine Pitrou32669782010-07-11 12:14:05 +00003544- Issue #7616: Fix copying of overlapping memoryview slices with the Intel

3654 SSLSocket.sendto() to match the corresponding socket methods. Also,
3655 fix various SSLSocket methods to raise socket.error rather than an
3656 unhelpful TypeError when called on an unconnected socket. Original patch
3657 by Andrew Bennetts.

3666
Raymond Hettinger20397532010-09-12 02:11:45 +00003667- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3668 This prevents user-created self-referencing ordered dictionaries from
3669 becoming permanently uncollectable GC garbage. The downside is that
3670 removing __del__ means that the internal doubly-linked list has to wait for
3671 GC collection rather than freeing memory immediately when the refcnt drops
3672 to zero.
3673
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003674- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00003675 different internal state for small values of n. Fixed by salting the

3677
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003678- Issue #9792: In case of connection failure, socket.create_connection()
3679 would swallow the exception and raise a new one, making it impossible
3680 to fetch the original errno, or to filter timeout errors. Now the
3681 original error is re-raised.
3682
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003683- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3684 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3685 be updated back after the system call. Original patch by Brian Brazil.
3686
Antoine Pitroudca9de92010-09-04 17:52:26 +00003687- Issue #1100562: Fix deep-copying of objects derived from the list and

3691 ConfigParser.write.
3692
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003693- Issue #808164: Fixed socket.close to avoid references to globals, to
3694 avoid issues when socket.close is called from a __del__ method.
3695
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003696- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

3698 heuristic. Patch by Terry Reedy and Eli Bendersky

3701 falling into recursion.
3702
R. David Murray7c4bf552010-08-25 01:45:57 +00003703- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3704 character years even if the message contains RFC822 two character years.
3705
Daniel Stutzbach91287322010-08-24 21:09:30 +00003706- Issue #8750: Fixed MutableSet's methods to correctly handle

3718 module now correctly return a set. (Patch by Eli Bendersky.)
3719
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003720- Issue #9617: Signals received during a low-level write operation aren't
3721 ignored by the buffered IO layer anymore.
3722
Benjamin Peterson52c36052010-08-21 03:03:22 +00003723- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3724 are not held onto after they are deleted elsewhere.
3725
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003726- Issue #9626: the view methods for collections.OrderedDict() were returning

3731 comment indicating they are generated. Manually maintained MANIFESTs
3732 without this marker will not be overwritten or removed.
3733
Antoine Pitroue1436d12010-08-12 15:25:51 +00003734- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3735 and a BadZipfile error is raised if it doesn't match (as used to be the
3736 case in Python 2.5 and earlier).
3737
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003738- Issue #9550: a BufferedReader could issue an additional read when the
3739 original read request had been satisfied, which could block indefinitely
3740 when the underlying raw IO channel was e.g. a socket. Report and original
3741 patch by Jason V. Miller.
3742
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003743- Issue #9551: Don't raise TypeError when setting the value to None for

3760
Senthil Kumarane677ecf2010-08-08 11:56:31 +00003761- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3762 This is how it is supposed to work, wget and curl do the same. Previous
3763 behavior was wrong.

3771 the option character for the added 'h/help' option if prefix_chars
3772 does not contain a '-', instead of raising an error.

4129
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004130- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4131 start byte and the continuation byte(s) are now considered invalid, instead
4132 of the number of bytes specified by the start byte.
4133 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4134 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4135 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4136 Previous versions returned a single u'\ufffd'.

4140 arises from the "Overriding __eq__ blocks inheritance ..." warning
4141 when turned into an exception: in this case the exception simply
4142 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004144- Issue #8748: Fix two issues with comparisons between complex and integer
4145 objects. (1) The comparison could incorrectly return True in some cases
4146 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4147 (2) The comparison raised an OverflowError for large integers, leading
4148 to unpredictable exceptions when combining integers and complex objects
4149 in sets or dicts.
4150
Mark Dickinson81336372010-05-30 12:12:25 +00004151- Issue #5211: Implicit coercion for the complex type is now completely
4152 removed. (Coercion for arithmetic operations was already removed in 2.7
4153 alpha 4, but coercion for rich comparisons was accidentally left in.)
4154
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004155- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00004342- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4343 operation raises multiple signals and more than one of those signals is
4344 trapped, the specification determines the order in which the signals should be
4345 handled. In many cases this order wasn't being followed, leading to the wrong
4346 Python exception being raised.

4532 with a non-empty format string. This is an effort to future-proof user
4533 code. If a derived class does not currently implement __format__ but later
4534 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004535 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004536 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004586- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4587 InvalidOperation instead of returning False. (Comparisons involving a quiet
4588 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4589 signaling NaNs remain unhashable.

4593 returned an arbitrary result based on the relative ordering of id(float) and
4594 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004596- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004597 argument `-` which tells it to read files to compile from stdin. Each line is
4598 read on demand and the named file is compiled immediately. (Original patch by
4599 Piotr Ożarowski).

4609 Fractions instance now raise TypeError instead of returning True/False. This
4610 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4611 <=> complex, and complex <=> complex comparisons.

4711 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004715- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4716 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4717 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004718 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4719 inconsistent: __int__ was used for some integer codes but not for others, and
4720 the set of integer codes for which it was used differed between native packing
4721 and standard packing.)

5126-----------------
5127
Georg Brandlba83f822010-03-14 09:50:54 +00005128- The ``__complex__()`` method is now looked up on the class of instances to
5129 make it consistent with other special methods.

5133
Mark Dickinson1b34d252010-01-01 17:27:30 +00005134- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005135 DeprecationWarning when passed a float argument where an integer was expected.
5136 These functions and methods now raise TypeError instead. The majority of the
5137 effects of this change are in the extension modules, but some core functions
5138 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5139 and many unicode/str methods.

5154 least on IEEE 754 platforms), and in particular does not depend on the
5155 internal representation of a long.

5163
Georg Brandlba83f822010-03-14 09:50:54 +00005164 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005303- Issue #3382: 'F' formatting for float and complex now convert the result to
5304 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5305 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005306
Georg Brandlba83f822010-03-14 09:50:54 +00005307- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5308 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005309
Georg Brandlba83f822010-03-14 09:50:54 +00005310- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5311 1e-100 used to raise OverflowError, but now gives the requested 120
5312 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00005313

5319 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005320
Georg Brandlba83f822010-03-14 09:50:54 +00005321- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5322 decimal string that's guaranteed to round back to x under correct rounding
5323 (with round-half-to-even rounding mode). Previously it gave a string based on
5324 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5325 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5326 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005327
Georg Brandlba83f822010-03-14 09:50:54 +00005328- Issue #7117: On almost all platforms: float-to-string and string-to-float
5329 conversions within Python are now correctly rounded. Places these conversions
5330 occur include: str for floats and complex numbers; the float and complex
5331 constructors; old-style and new-style numeric formatting; serialization and
5332 deserialization of floats and complex numbers using marshal, pickle and json;
5333 parsing of float and imaginary literals in Python code; Decimal-to-float
5334 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005335
Georg Brandlba83f822010-03-14 09:50:54 +00005336 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5337 providing correctly-rounded strtod and dtoa C functions. This code is
5338 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5339 the C compiler. There may be a small number of platforms on which correct
5340 operation of this code cannot be guaranteed, so the code is not used: notably,
5341 this applies to platforms where the C double format is not IEEE 754 binary64,
5342 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5343 and Python's configure script is unable to determine how to change the FPU
5344 precision. On these platforms conversions use the platform strtod and dtoa,
5345 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005346
Georg Brandlba83f822010-03-14 09:50:54 +00005347- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5348 uses the correctly-rounded string <-> float conversions described above (when
5349 available), and so produces correctly rounded results that will display nicely
5350 under the float repr. There are two related small changes: (1) round now
5351 accepts any class with an ``__index__()`` method for its second argument (but
5352 no longer accepts floats for the second argument), and (2) an excessively
5353 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5354 raises an exception.

5357
Georg Brandlba83f822010-03-14 09:50:54 +00005358- Fix several issues with ``compile()``. The input can now contain Windows and

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005571- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005572 untrackable objects are not tracked by the garbage collector. This can reduce
5573 the size of collections and therefore the garbage collection overhead on
5574 long-running programs, depending on their particular use of datatypes.

5581 internal representation of integers, for performance reasons. Base 2**30 is
5582 enabled by default on 64-bit machines. Add --enable-big-digits option to
5583 configure, which overrides the default. Add sys.long_info structseq to
5584 provide information about the internal format.

Brett Cannon6c4cff02009-03-11 04:51:06 +00005597 requirement. Means the DeprecationWarning from Python 2.6 can go away.
5598
Georg Brandlba83f822010-03-14 09:50:54 +00005599- Issue #5247: Improve error message when unknown format codes are used when
5600 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00005601
Georg Brandlba83f822010-03-14 09:50:54 +00005602- Running Python with the -3 option now also warns about classic division for

Benjamin Petersone18ef192009-01-20 14:21:16 +00005614- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
5615
Georg Brandl29c6a282009-04-05 20:23:13 +00005616- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00005617 were suppressing all exceptions. These include list(), filter(), map(),
5618 zip(), and bytearray().
5619
Benjamin Peterson596d3062009-01-19 15:42:23 +00005620- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00005647- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5648 existing .py counterpart, override the co_filename attributes of all code
5649 objects if the original filename is obsolete (which can happen if the file has
5650 been renamed, moved, or if it is accessed through different paths). Patch by

5704
Georg Brandlba83f822010-03-14 09:50:54 +00005705- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5706 file objects with closefd=False. The file descriptor is still kept open but
5707 the file object behaves like a closed file. The ``FileIO`` object also got a

5733 this code path is really executed because I cannot move to such directory on

7137
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007138- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7139
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007140- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7141 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7142 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7143 ``printf`` function, whereas PyString_FromFormat has an independent
7144 implementation and uses "%zd" on all platforms for size_t values.
7145 This makes a difference on win64, where ``printf`` needs "%Id" to display
7146 64bit values.
7147
Benjamin Peterson97179b02008-09-09 20:55:01 +00007148- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7149 error.
7150
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007151- Issue #3777: long() applied to a float object now always return a long
7152 object; previously an int would be returned for small values. the __long__
7153 method is allowed to return either an int or a long, but the behaviour of
7154 float objects should not change to respect backward compatibility.
7155
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007156- Issue #3751: str.rpartition would perform a left-partition when called with
7157 a unicode argument.
7158
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007159- Issue #3683: Fix compilation when --without-threads is given.
7160
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007161- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007162 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007163 was correctly parsed but parsing of subsequent arguments failed.
7164
Vinay Sajip35e3b032008-09-01 14:33:59 +00007165- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007166 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7167 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7168 when given a tuple of classes as second argument, were looking up
7169 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7170 type object.
7171
Neal Norwitz18aa3882008-08-24 05:04:52 +00007172- Fix crashes on memory allocation failure found with failmalloc.
7173
7174- Fix memory leaks found with valgrind and update suppressions file.
7175
7176- Fix compiler warnings in opt mode which would lead to invalid memory reads.
7177
7178- Fix problem using wrong name in decimal module reported by pychecker.
7179
Christian Heimes7d4c3172008-08-22 19:47:25 +00007180- Silenced another compiler warning about a used but not defined
7181 function 'stringlib_contains_obj'.

7187 library targets in the Makefile.
7188
Gregory P. Smith980b99b2008-09-07 05:15:18 +00007189- Issue #1204: The configure script now tests for additional libraries

Brett Cannon1eaf0742008-09-02 01:25:16 +00007241 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7242 for catch_warnings() also led to an improvement in the raising of a
7243 DeprecationWarning related to warnings.warn_explicit().
7244
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007245- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007309What's New in Python 2.6 beta 3?
7310================================
7311
Barry Warsaw07a4a382008-08-21 01:15:08 +00007312*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007313
7314Core and Builtins
7315-----------------
7316
Guido van Rossumf8402962008-08-20 15:01:50 +00007317- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7318 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7319 extensions do not automatically benefit from the class attribute
7320 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7321 to their tp_flags field if they care. This is a backwards
7322 compatibility feature; in 3.0, all types will use the cache by
7323 default.
7324
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007325- Keyword arguments can now follow starred arguments. (``f(a, *args,
7326 keyword=23)`` is now valid syntax.)
7327
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007328- ctypes function pointers that are COM methods have a boolean True
7329 value again.
7330
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007331- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7332 by denying s# to parse objects that have a releasebuffer procedure,
7333 and introducing s*.
7334
Georg Brandl1e13ea92008-08-11 09:07:59 +00007335- Issue #3537: Fix an assertion failure when an empty but presized dict
7336 object was stored in the freelist.
7337
Mark Dickinsonb6467572008-08-04 21:30:09 +00007338- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7339 ValueError consistently across platforms.
7340
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007341- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7342 (64bit Unix, for example), unichr() would truncate its argument and return
7343 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7344
Neal Norwitze7d8be82008-07-31 17:17:14 +00007345- Apply security patches from Apple.
7346
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007347- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7348 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7349
Antoine Pitrou92f82162008-07-25 22:22:08 +00007350- Issue #1819: function calls with several named parameters are now on
7351 average 35% faster (as measured by pybench).
7352
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007353- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7354 the python debugger steps into a class statement: the free variables (local
7355 variables defined in an outer scope) would be deleted from the outer scope.
7356
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007357- Issue #2620: Overflow checking when allocating or reallocating memory
7358 was not always being done properly in some python types and extension
7359 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7360 all been updated to perform better checks and places in the code that
7361 would previously leak memory on the error path when such an allocation
7362 failed have been fixed.

7370 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7371
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007372- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7373 version reported by these tools does not necessarily follow the python
7374 version numbering scheme, so the module is less strict when parsing it.
7375
Nick Coghlanf70385a2008-08-18 12:42:46 +00007376- Issue #2235: Added Py3k warnings for types which will become unhashable
7377 under the stricter __hash__ inheritance rules in 3.0. Several types
7378 which did not meet the rules for hash invariants and were already
7379 unhashable in 3.0 have now been explicitly flagged as unhashable in
7380 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7381 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7382
Brett Cannon88f801d2008-08-18 00:46:22 +00007383- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7384 imported into the module but exposed as part of the module's API.
7385

7391
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007392- Issue #3575: Incremental decoder's decode function now takes bytearray
7393 by using 's*' instead of 't#'.
7394
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007395- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007396 fails unicode conversion on 2nd parameter. (windows only)
7397
Georg Brandl222e2082010-08-01 22:27:39 +00007398- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007399 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00007402 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007403
Facundo Batistaeb90b782008-08-16 14:44:07 +00007404- Issue #2776: fixed small issue when handling an URL with double slash
7405 after a 302 response in the case of not going through a proxy.
7406
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007407- Issue #2676: in the email package, content-type parsing was hanging on
7408 pathological input because of quadratic or exponential behaviour of a
7409 regular expression.
7410
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007411- Issue #3476: binary buffered reading through the new "io" library is now

Antoine Pitroude781a42008-08-09 12:43:23 +00007452 asking for a specific length. This problem only affected files opened

7496
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007497- Issue #643841: The language reference now provides more detailed

7510
Georg Brandl3e483f62008-07-16 22:57:41 +00007511- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7512 its methods now allow for items objects that can be converted to
7513 an integer using operator.index().
7514
Mark Dickinson64b7e502008-07-16 09:40:03 +00007515- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7516 produced a ValueError instead of giving the correct float.
7517
Eric Smitha5fa5a22008-07-16 00:11:49 +00007518- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

7520
Mark Dickinson7103aa42008-07-15 19:08:33 +00007521- Issue #3008: the float type has a new instance method 'float.hex'
7522 and a new class method 'float.fromhex' to convert floating-point
7523 numbers to and from hexadecimal strings, respectively.
7524
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007525- Issue #2235: __hash__ is once again inherited by default. To allow
7526 collections.Hashable to remain meaningful in the presence of the
7527 default hash implementation (object.__hash__), it is now possible
7528 to explicit block inheritance of hash by setting __hash__=None at
7529 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7530 level.
7531
Nick Coghlanb028f502008-07-13 14:52:36 +00007532- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7533 the parent module cannot be found while performing an absolute import.
7534 This means that an incorrectly defined __package__ attribute will
7535 now only prevent relative imports in that module rather than causing
7536 all imports from that module to fail.
7537
Nick Coghlan14ff9942008-07-08 14:21:42 +00007538- Issue #2517: Allow unicode messages in Exceptions again by correctly

7548 another thread's dictionary.
7549
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007550- Issue #3004: Minor change to slice.indices(): the start and stop
7551 arguments are now treated identically, making the behaviour easier
7552 to describe and understand. For example, slice(None, -10,
7553 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7554 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7555 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007557- Issue #3219: Calling a function with repeated keyword arguments,

7598 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007599 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007600 content-length. The problem had been corrected in the 2.4 branch, but never

Vinay Sajip9828b7e2008-06-17 11:04:02 +00007985- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007986 environment to control the '-arch' flags that are used to build
7987 an extension. This was added for compatibility with Apple's build
7988 of Python.
7989
7990- The bundled OSX-specific copy of libbffi is now in sync with the version
7991 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.

8002
Brett Cannonb61d8012008-05-11 23:39:04 +00008003- ``Lib/lib-old`` is now added to sys.path.
8004
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008005- On MacOS X it is now possible to install the framework in 64-bit
8006 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008007 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008008
8009 This is controlled by the configure argument ``--with-universal-archs``:
8010
8011 - ``--with-universal-archs=all``: install 4-way universal
8012
8013 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8014
8015 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8016
8017 This option should be used in combination with ``--enable-universalsdk=``.
8018
8019 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 +00008068- Issue #1631171: Re-implement the 'warnings' module in C (the
8069 original Python code has been kept as backup). This will allow for
8070 using the 'warning's machinery in such places as the parser where
8071 use of pure Python code is not possible. Both the ``showarning()``
8072 and ``formatwarning()`` gain an optional 'line' argument which is
8073 not called by default for backwards-compatibility reasons. Setting
8074 ``warnings.showwarning()`` to an implementation that lacks support
8075 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008117- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008118 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008138- Issue #2550: The approach used by client/server code for obtaining
8139 ports to listen on in network-oriented tests has been refined in an
8140 effort to facilitate running multiple instances of the entire
8141 regression test suite in parallel without issue.
8142 test_support.bind_port() has been fixed such that it will always
8143 return a unique port -- which wasn't always the case with the
8144 previous implementation, especially if socket options had been set
8145 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8146 new implementation of bind_port() will actually raise an exception
8147 if it is passed an AF_INET/SOCK_STREAM socket with either the
8148 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8149 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8150 the socket it's been passed. This currently only applies to
8151 Windows. This option prevents any other sockets from binding to the
8152 host/port we've bound to, thus removing the possibility of the
8153 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8154 when a second SOCK_STREAM socket binds and accepts to a host/port
8155 that's already been bound by another socket. The optional preferred
8156 port parameter to bind_port() has been removed. Under no
8157 circumstances should tests be hard coding ports!
8158
8159 test_support.find_unused_port() has also been introduced, which will
8160 pass a temporary socket object to bind_port() in order to obtain an
8161 unused port. The temporary socket object is then closed and
8162 deleted, and the port is returned. This method should only be used
8163 for obtaining an unused port in order to pass to an external program
8164 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8165 a parameter to a server-oriented class that doesn't give you direct
8166 access to the underlying socket used.
8167
8168 Finally, test_support.HOST has been introduced, which should be used
8169 for the host argument of any relevant socket calls (i.e. bind and
8170 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008171
8172 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008173 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008174 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8175 test_asynchat and test_socket_ssl.
8176
Georg Brandl3ee81df2008-05-17 18:14:43 +00008177 It is now possible for multiple instances of the regression test
8178 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008457- Added the future_builtins module, which contains hex() and oct().
8458 These are the PEP 3127 version of these functions, designed to be
8459 compatible with the hex() and oct() builtins from Python 3.0. They
8460 differ slightly in their output formats from the existing, unchanged
8461 Python 2.6 builtins. The expected usage of the future_builtins
8462 module is:
8463 from future_builtins import hex, oct
8464
Eric Smith7ef40bf2008-02-20 23:34:22 +00008465- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8466 exponents for exponents with absolute value < 100. Follows C99
8467 standard. This is a change on Windows, which would use 3 digits.
8468 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8469 so that any alterations it does to the resulting string will be
8470 available in stringlib/formatter.h (for float.__format__).
8471
Eric Smith5a3c1352008-02-19 13:21:56 +00008472- Implemented PEP 3101, Advanced String Formatting. This adds a new
8473 builtin format(); a format() method for str and unicode; a
8474 __format__() method to object, str, unicode, int, long, float, and
8475 datetime; the class string.Formatter; and the C API
8476 PyObject_Format().
8477
Georg Brandl3ee81df2008-05-17 18:14:43 +00008478- Fixed several potential crashes, all caused by specially crafted
8479 __del__ methods exploiting objects in temporarily inconsistent
8480 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00008482- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008483 prevent a possible crash: an Abstract Base Class would try to access
8484 a slot on a registered virtual subclass.

8490 in order to allow pymalloc to free more arenas. Python may give back
8491 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008492
Georg Brandl3ee81df2008-05-17 18:14:43 +00008493- Issue #2045: Fix an infinite recursion triggered when printing a
8494 subclass of collections.defaultdict, if its default_factory is set
8495 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008496
Christian Heimesf75dbef2008-02-08 00:11:31 +00008497- Fixed a minor memory leak in dictobject.c. The content of the free
8498 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00008500- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008501 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008502
Georg Brandl3ee81df2008-05-17 18:14:43 +00008503- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8504 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008505 to compact the internal free lists of pre-allocted ints and floats.
8506
Georg Brandl3ee81df2008-05-17 18:14:43 +00008507- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8508 calls. Python expected the return type int but the fork familie
8509 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008510
Georg Brandl3ee81df2008-05-17 18:14:43 +00008511- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8512 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008513
Georg Brandl3ee81df2008-05-17 18:14:43 +00008514- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8515 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008516
Georg Brandl3ee81df2008-05-17 18:14:43 +00008517- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8518 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00008520- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8521 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008522
Georg Brandl3ee81df2008-05-17 18:14:43 +00008523- Patch #1473257: generator objects gain a gi_code attribute. This is
8524 the same object as the func_code attribute of the function that
8525 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008526
Georg Brandl3ee81df2008-05-17 18:14:43 +00008527- Issue #1920: "while 0" statements were completely removed by the
8528 compiler, even in the presence of an "else" clause, which is
8529 supposed to be run when the condition is false. Now the compiler
8530 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008531
Guido van Rossumeead05f2008-01-24 18:21:02 +00008532- A few crashers fixed: weakref_in_del.py (issue #1377858);
8533 loosing_dict_ref.py (issue #1303614, test67.py);
8534 borrowed_ref_[34].py (not in tracker).
8535
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008536- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008537 suppressed while an extension is loaded by calling SetErrorMode in
8538 dynload_win.c. The error is still reported properly.
8539
Georg Brandl3ee81df2008-05-17 18:14:43 +00008540- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008541 several extension methods and modules do not work without unicode
8542 support.
8543
Georg Brandl26543b12008-01-21 18:36:51 +00008544- Issue #1882: when compiling code from a string, encoding cookies in the
8545 second line of code were not always recognized correctly.
8546
Georg Brandl14404b62008-01-19 19:27:05 +00008547- Issue #1679: "0x" was taken as a valid integer literal.
8548
Georg Brandl6caad7d2008-01-26 14:19:22 +00008549- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008550 added.
8551
Christian Heimesc94e2b52008-01-14 04:13:37 +00008552- sys.float_info / PyFloat_GetInfo: The floating point information
8553 object was converted from a dict to a specialized structseq object.
8554
Georg Brandl3ee81df2008-05-17 18:14:43 +00008555- Patch #1816: Added sys.flags structseq. It exposes the status of
8556 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008557
Georg Brandl3ee81df2008-05-17 18:14:43 +00008558- Objects/structseq.c: Implemented new structseq representation. The
8559 patch makes structseqs (e.g. the return value of os.stat) more
8560 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008561
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562- Patch #1700288: added a type attribute cache that caches method
8563 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008564
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008565- Bug #1776: __import__() no longer accepts filenames on any platform.
8566 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008567
Georg Brandlaed6c662008-01-07 17:25:53 +00008568- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8569
Georg Brandl3ee81df2008-05-17 18:14:43 +00008570- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8571 envvar and sys.dont_write_bytecode attribute. All these can be set
8572 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008573
Georg Brandl3ee81df2008-05-17 18:14:43 +00008574- Improve some exception messages when Windows fails to load an
8575 extension module. Now we get for example '%1 is not a valid Win32
8576 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008577
Georg Brandl3ee81df2008-05-17 18:14:43 +00008578- Bug #1481296: Fixed long(float('nan')) != 0L.

8581 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008582
Christian Heimes0a8143f2007-12-18 23:22:54 +00008583- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008584 and INF. float("nan"), float("inf") and float("-inf") now work on
8585 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008586
Georg Brandl3ee81df2008-05-17 18:14:43 +00008587- Compiler now generates simpler and faster code for dictionary
8588 literals. The oparg for BUILD_MAP now indicates an estimated
8589 dictionary size. There is a new opcode, STORE_MAP, for adding
8590 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008591
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008600- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008601 SystemError.
8602
Nick Coghlanef01d822007-12-03 12:55:17 +00008603- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00008619- Patch #1739468: Directories and zipfiles containing a __main__.py
8620 file can now be directly executed by passing their name to the
8621 interpreter. The directory/zipfile is automatically inserted as the
8622 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008623
Georg Brandl3ee81df2008-05-17 18:14:43 +00008624- Issue #1265: Fix a problem with sys.settrace, if the tracing
8625 function uses a generator expression when at the same time the
8626 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008627
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008628- sets and frozensets now have an isdisjoint() method.
8629
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008630- optimize the performance of builtin.sum().
8631
Neal Norwitz44f326e2007-10-05 05:29:17 +00008632- Fix warnings found by the new version of the Coverity checker.
8633
Georg Brandl21e99f42010-03-07 15:23:59 +00008634- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008635 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8636 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008637
Georg Brandl3ee81df2008-05-17 18:14:43 +00008638- Issue #1686386: Tuple's tp_repr did not take into account the
8639 possibility of having a self-referential tuple, which is possible
8640 from C code. Nor did object's tp_str consider that a type's tp_str
8641 could do something that could lead to an inifinite recursion.
8642 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8643 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008644
Georg Brandl3ee81df2008-05-17 18:14:43 +00008645- Issue #1164: It was possible to trigger deadlock when using the
8646 'print' statement to write to a file since the GIL was not released
8647 as needed. Now PyObject_Print() does the right thing along with
8648 various tp_print implementations of the built-in types and those in
8649 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008650
Georg Brandl3ee81df2008-05-17 18:14:43 +00008651- Issue #1147: Exceptions were directly allowing string exceptions in
8652 their throw() method even though string exceptions no longer
8653 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008654
Georg Brandl3ee81df2008-05-17 18:14:43 +00008655- Issue #1096: Prevent a segfault from getting the repr of a very
8656 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008657
Brett Cannon1e534b52007-09-07 04:18:30 +00008658- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008659 PyObject_Call() never calling back out to Python code to trigger
8660 recursion depth updates/checks. Required the creation of a static
8661 RuntimeError instance in case normalizing an exception put the
8662 recursion check value past its limit. Fixes crashers
8663 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008664
Georg Brandl3ee81df2008-05-17 18:14:43 +00008665- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008678- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008679 __*__ attributes. (Some already existed, e.g., __doc__ and
8680 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008681
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008682- Add -3 option to the interpreter to warn about features that are
8683 deprecated and will be changed/removed in Python 3.0.
8684
Georg Brandl2134e752007-05-21 20:34:16 +00008685- Patch #1686487: you can now pass any mapping after '**' in function
8686 calls.
8687
Collin Winter62903052007-05-18 23:11:24 +00008688- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008689 "except E as target:". This is to provide forwards compatibility
8690 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00008692- Deprecate BaseException.message as per PEP 352.
8693
Georg Brandl3ee81df2008-05-17 18:14:43 +00008694- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008695 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008697- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008698 setting a plain string, ie don't expand to single letter identifiers.
8699
Raymond Hettinger13936692007-04-11 18:40:58 +00008700- Request #1191699: Slices can now be pickled.
8701
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008702- Request #1193128: str.translate() now allows a None argument for
8703 translations that only remove characters without re-mapping the
8704 remaining characters.
8705
Georg Brandl5cb76c12007-03-21 09:00:39 +00008706- Patch #1682205: a TypeError while unpacking an iterable is no longer
8707 masked by a generic one with the message "unpack non-sequence".
8708
Neal Norwitzaa754b72007-03-21 06:39:48 +00008709- Remove unused file Python/fmod.c.
8710
Guido van Rossum143b5642007-03-23 04:58:42 +00008711- Bug #1683368: The object.__init__() and object.__new__() methods are
8712 now stricter in rejecting excess arguments. The only time when
8713 either allows excess arguments is when it is not overridden and the
8714 other one is. For backwards compatibility, when both are
8715 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008716 warning later). Also, type.__init__() insists on the same signature
8717 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008719- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8720 object to complex using its __complex__() method before falling back
8721 to the __float__() method. Therefore, the functions in the cmath
8722 module now can operate on objects that define a __complex__()
8723 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009270 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009311 AttributeError instead of an IOError when the server's response
9312 didn't contain a valid HTTP status line.

9344
Georg Brandl92a6bae2007-03-13 17:43:32 +00009345- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009346 are set for invalid interpolation sequences that would lead to
9347 errors on reading back those values.

9403 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00009790 time so that opening a database previously created with the DB_DUP
9791 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9792 opens. Specifically: dictionary assignment to a DB object will
9793 replace all values for a given key when the database allows
9794 duplicate values. DB users should use DB.put(k, v) when they want
9795 to store duplicates; not DB[k] = v.

9804 behavior of quoting dots if they are the second character of any
9805 line.
