683
684- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
685 and later systems as is currently done for Python 3.x installers.
686 For 2.7.7 only, we will provide three installers:
687 the legacy deprecated 10.3+ 32-bit-only format;
688 the newer 10.5+ 32-bit-only format;
689 and the unchanged 10.6+ 64-/32-bit format.
690 Although binary installers will no longer be available from
691 python.org as of 2.7.8, it will still be possible to build from
692 source on 10.3.9 and 10.4 systems if necessary.
693 See Mac/BuildScript/README.txt for more information.

Nadeem Vawda252f4dc2012-11-11 02:14:15 +01001749 to the last call. decompressobj().flush() now correctly sets unused_data and
1750 unconsumed_tail. A bug in the handling of MemoryError when setting the
1751 unconsumed_tail attribute has also been fixed. Patch by Serhiy Storchaka.

Ned Deily18fae3f2013-01-31 01:24:55 -08002073- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
2074 In particular, fix extension module build failures when trying to use
2075 32-bit-only installer Pythons on systems with Xcode 4 (currently
2076 OS X 10.8, 10.7, and optionally 10.6).
2077 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2078 * Since Xcode 4 removes ppc support, extension module builds now
2079 check for ppc compiler support and by default remove ppc and
2080 ppc64 archs when they are not available.
2081 * Extension module builds now revert to using system installed
2082 headers and libs (/usr and /System/Library) if the SDK used
2083 to build the interpreter is not installed or has moved.
2084 * Try to avoid building extension modules with deprecated
2085 and problematic Apple llvm-gcc compiler. If original compiler
2086 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002450- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2451 int.__pow__. These overflow checks were causing int.__pow__ to produce
2452 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002453 compiler optimizing the check away. Also fix similar overflow checks
2454 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

2467 cleared by the garbage collector. This fixes a segfault when an instance
2468 and its type get caught in a reference cycle, and the instance's
2469 deallocator calls one of the methods on the type (e.g. when subclassing
2470 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01002523- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002524 has left two versions of customize_compiler, the original in
2525 distutils.sysconfig and another copy in distutils.ccompiler, with some
2526 parts of distutils calling one and others using the other.

2528 is the case in 3.x.
2529
Ned Deily0d0ea482012-02-10 12:59:06 +01002530- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2531 Distutils-based packages with C extension modules may fail because
2532 Apple has removed gcc-4.2, the version used to build python.org
2533 64-bit/32-bit Pythons. If the user does not explicitly override
2534 the default C compiler by setting the CC environment variable,
2535 Distutils will now attempt to compile extension modules with clang
2536 if gcc-4.2 is required but not found. Also as a convenience, if
2537 the user does explicitly set CC, substitute its value as the default
2538 compiler in the Distutils LDSHARED configuration variable for OS X.
2539 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2540 SDK, neither of which are available in Xcode 4. This change does not
2541 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002791- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2792 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2793 interpreter process. This could cause failures in non-Distutils subprocesses
2794 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002795 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002796 deployment target only in the environment of each build subprocess. It is
2797 still possible to globally override the default by setting
2798 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2799 greater or equal to the default value, the value with which the interpreter
2800 was built.

2827
Barry Warsawc5643282011-07-19 17:06:30 -04002828- sys.setcheckinterval() now updates the current ticker count as well as
2829 updating the check interval, so if the user decreases the check interval,
2830 the ticker doesn't have to wind down to zero from the old starting point
2831 before the new interval takes effect. And if the user increases the
2832 interval, it makes sure the new limit takes effect right away rather have an
2833 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003830- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3831 This prevents user-created self-referencing ordered dictionaries from
3832 becoming permanently uncollectable GC garbage. The downside is that
3833 removing __del__ means that the internal doubly-linked list has to wait for
3834 GC collection rather than freeing memory immediately when the refcnt drops
3835 to zero.

3865
R. David Murray7c4bf552010-08-25 01:45:57 +00003866- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3867 character years even if the message contains RFC822 two character years.
3868
Daniel Stutzbach91287322010-08-24 21:09:30 +00003869- Issue #8750: Fixed MutableSet's methods to correctly handle

3898 and a BadZipfile error is raised if it doesn't match (as used to be the
3899 case in Python 2.5 and earlier).
3900
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003901- Issue #9550: a BufferedReader could issue an additional read when the
3902 original read request had been satisfied, which could block indefinitely
3903 when the underlying raw IO channel was e.g. a socket. Report and original
3904 patch by Jason V. Miller.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004654 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4655 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4656 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4677-----------------
4678
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004679- Issue #7301: Add environment variable $PYTHONWARNINGS.
4680
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004681- Issue #8329: Don't return the same lists from select.select when no fds are
4682 changed.
4683
Georg Brandlfee0f442010-05-22 21:26:21 +00004684- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004685 on 64-bit machines. The shift count for either left or right shift is
4686 permitted to be up to sys.maxsize.
4687
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004688- Ensure that tokenization of identifiers is not affected by locale.
4689
Georg Brandlfee0f442010-05-22 21:26:21 +00004690- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004691
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004692- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4693
Georg Brandlfee0f442010-05-22 21:26:21 +00004694- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4695 with a non-empty format string. This is an effort to future-proof user
4696 code. If a derived class does not currently implement __format__ but later
4697 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004698 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004699 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004700
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004701- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00004714- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004715 (SIGINT). If an error occurs while importing the site module, the error is

4731
Georg Brandlfee0f442010-05-22 21:26:21 +00004732- Issue #8257: The Decimal construct now accepts a float instance directly,
4733 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004734
4735 >>> Decimal(1.1)
4736 Decimal('1.100000000000000088817841970012523233890533447265625')
4737
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004738- collections.Counter() now supports a subtract() method.
4739
Georg Brandlfee0f442010-05-22 21:26:21 +00004740- The functools module now has a total_ordering() class decorator to simplify
4741 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004742
Georg Brandlfee0f442010-05-22 21:26:21 +00004743- The functools module also adds cmp_to_key() as a tool to transition old-style
4744 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004745
Georg Brandlfee0f442010-05-22 21:26:21 +00004746- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4747 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00004749- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4750 InvalidOperation instead of returning False. (Comparisons involving a quiet
4751 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4752 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004753
Georg Brandlfee0f442010-05-22 21:26:21 +00004754- Issue #2531: Comparison operations between floats and Decimal instances now
4755 return a result based on the numeric values of the operands; previously they
4756 returned an arbitrary result based on the relative ordering of id(float) and
4757 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004758
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004759- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004760 argument `-` which tells it to read files to compile from stdin. Each line is
4761 read on demand and the named file is compiled immediately. (Original patch by
4762 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004767- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4768 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004769 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004770
Georg Brandlfee0f442010-05-22 21:26:21 +00004771- Comparisons using one of <, <=, >, >= between a complex instance and a
4772 Fractions instance now raise TypeError instead of returning True/False. This
4773 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4774 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004842- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004873- Issue #8300: When passing a non-integer argument to struct.pack with any
4874 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004878- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4879 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4880 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004881 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4882 inconsistent: __int__ was used for some integer codes but not for others, and
4883 the set of integer codes for which it was used differed between native packing
4884 and standard packing.)

5137 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5138 returning NULL. The macro now returns a statically allocated empty string
5139 instead.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005191- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005192 file position when calling `truncate()`. It would previously change the file
5193 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005194 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5195

5197 class used to represent files stored inside an archive. The new
5198 implementation is significantly faster and can be wrapped in a
5199 ``io.BufferedReader`` object for more speedups. It also solves an issue
5200 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
5201 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00005211- Issue #7748: Since unicode values are supported for some metadata options in
5212 Distutils, the DistributionMetadata get_* methods will now return an utf-8
5213 encoded string for them. This ensures that the upload and register commands
5214 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00005484- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5485 decimal string that's guaranteed to round back to x under correct rounding
5486 (with round-half-to-even rounding mode). Previously it gave a string based on
5487 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5488 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5489 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005490
Georg Brandlba83f822010-03-14 09:50:54 +00005491- Issue #7117: On almost all platforms: float-to-string and string-to-float
5492 conversions within Python are now correctly rounded. Places these conversions
5493 occur include: str for floats and complex numbers; the float and complex
5494 constructors; old-style and new-style numeric formatting; serialization and
5495 deserialization of floats and complex numbers using marshal, pickle and json;
5496 parsing of float and imaginary literals in Python code; Decimal-to-float
5497 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005498
Georg Brandlba83f822010-03-14 09:50:54 +00005499 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5500 providing correctly-rounded strtod and dtoa C functions. This code is
5501 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5502 the C compiler. There may be a small number of platforms on which correct
5503 operation of this code cannot be guaranteed, so the code is not used: notably,
5504 this applies to platforms where the C double format is not IEEE 754 binary64,
5505 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5506 and Python's configure script is unable to determine how to change the FPU
5507 precision. On these platforms conversions use the platform strtod and dtoa,
5508 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005510- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5511 uses the correctly-rounded string <-> float conversions described above (when
5512 available), and so produces correctly rounded results that will display nicely
5513 under the float repr. There are two related small changes: (1) round now
5514 accepts any class with an ``__index__()`` method for its second argument (but
5515 no longer accepts floats for the second argument), and (2) an excessively
5516 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5517 raises an exception.

5666 but with at least one decimal point and with a default precision
5667 of 12. Previously, the behavior the same but with a default precision of 6.
5668 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00005810- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5811 existing .py counterpart, override the co_filename attributes of all code

5867
Georg Brandlba83f822010-03-14 09:50:54 +00005868- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5869 file objects with closefd=False. The file descriptor is still kept open but
5870 the file object behaves like a closed file. The ``FileIO`` object also got a
5871 new readonly attribute ``closefd``.

5890
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005891- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005894- On windows, ``os.chdir()`` given unicode was not working if
5895 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5896 this code path is really executed because I cannot move to such directory on
5897 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005899- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5900 element is temporarily replaced with an equivalent frozenset. But the
5901 eventual KeyError would always report the empty ``frozenset()`` as the missing
5902 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005922- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5923 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5924 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5925 of using the replace error handler in PyUnicode_DecodeUTF8().
5926
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005927- Issue #3739: The unicode-internal encoder now reports the number of characters

5929
Georg Brandlba83f822010-03-14 09:50:54 +00005930- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5931 allocator will be automatically disabled when running under Valgrind. This
5932 gives improved memory leak detection when running under Valgrind, while taking
5933 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007324- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7325 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7326 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7327 ``printf`` function, whereas PyString_FromFormat has an independent
7328 implementation and uses "%zd" on all platforms for size_t values.
7329 This makes a difference on win64, where ``printf`` needs "%Id" to display
7330 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00007350 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

7354 type object.

Georg Brandl222e2082010-08-01 22:27:39 +00007424- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00007425 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7426 for catch_warnings() also led to an improvement in the raising of a
7427 DeprecationWarning related to warnings.warn_explicit().
7428
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007429- The deprecation warnings for the old camelCase threading API were removed.
7430

7434
Christian Heimes1cc69632008-08-22 20:10:27 +00007435- Fixed two format strings in the _collections module.
7436

7451
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007452- Issue #2975: When compiling several extension modules with Visual Studio 2008
7453 from the same python interpreter, some environment variables would grow
7454 without limit.
7455
Benjamin Peterson37346b22008-08-23 20:27:43 +00007456- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7457 exploitation of poor argument checking.
7458
Gerhard Häringef2276b2008-09-12 13:54:06 +00007459- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
7460
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00007461- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
7462 remaining ones have "pysqlite_" prefix.
7463
Gerhard Häringe6872eb2008-09-12 22:33:22 +00007464- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

7472 wrapper for warnings.catch_warnings() that makes it easier to check
7473 that expected warning messages are being reported.
7474

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007493What's New in Python 2.6 beta 3?
7494================================
7495
Barry Warsaw07a4a382008-08-21 01:15:08 +00007496*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007497
7498Core and Builtins
7499-----------------
7500
Guido van Rossumf8402962008-08-20 15:01:50 +00007501- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7502 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7503 extensions do not automatically benefit from the class attribute
7504 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7505 to their tp_flags field if they care. This is a backwards
7506 compatibility feature; in 3.0, all types will use the cache by
7507 default.
7508
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007509- Keyword arguments can now follow starred arguments. (``f(a, *args,
7510 keyword=23)`` is now valid syntax.)
7511
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007512- ctypes function pointers that are COM methods have a boolean True
7513 value again.
7514
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007515- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7516 by denying s# to parse objects that have a releasebuffer procedure,
7517 and introducing s*.
7518
Georg Brandl1e13ea92008-08-11 09:07:59 +00007519- Issue #3537: Fix an assertion failure when an empty but presized dict
7520 object was stored in the freelist.
7521
Mark Dickinsonb6467572008-08-04 21:30:09 +00007522- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7523 ValueError consistently across platforms.
7524
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007525- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7526 (64bit Unix, for example), unichr() would truncate its argument and return
7527 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7528
Neal Norwitze7d8be82008-07-31 17:17:14 +00007529- Apply security patches from Apple.
7530
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007531- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7532 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7533
Antoine Pitrou92f82162008-07-25 22:22:08 +00007534- Issue #1819: function calls with several named parameters are now on
7535 average 35% faster (as measured by pybench).
7536
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007537- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7538 the python debugger steps into a class statement: the free variables (local
7539 variables defined in an outer scope) would be deleted from the outer scope.
7540
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007541- Issue #2620: Overflow checking when allocating or reallocating memory
7542 was not always being done properly in some python types and extension
7543 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7544 all been updated to perform better checks and places in the code that
7545 would previously leak memory on the error path when such an allocation
7546 failed have been fixed.
7547

7549-------
7550
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007551- Issue #3612: Added some missing basic types in ctypes.wintypes.
7552
Benjamin Petersone977ad42008-08-20 01:42:01 +00007553- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7554 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7555
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007556- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7557 version reported by these tools does not necessarily follow the python
7558 version numbering scheme, so the module is less strict when parsing it.
7559
Nick Coghlanf70385a2008-08-18 12:42:46 +00007560- Issue #2235: Added Py3k warnings for types which will become unhashable
7561 under the stricter __hash__ inheritance rules in 3.0. Several types
7562 which did not meet the rules for hash invariants and were already
7563 unhashable in 3.0 have now been explicitly flagged as unhashable in
7564 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7565 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7566
Brett Cannon88f801d2008-08-18 00:46:22 +00007567- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7568 imported into the module but exposed as part of the module's API.
7569
Brett Cannon7b96f072008-08-18 00:41:11 +00007570- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7571
Brett Cannon46225e72008-08-18 00:36:52 +00007572- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007574- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7575
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007576- Issue #3575: Incremental decoder's decode function now takes bytearray
7577 by using 's*' instead of 't#'.
7578
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007579- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007580 fails unicode conversion on 2nd parameter. (windows only)
7581
Georg Brandl222e2082010-08-01 22:27:39 +00007582- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007583 in a redirect.
7584
Brett Cannonabe423e2008-08-16 21:47:07 +00007585- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007586 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007587
Facundo Batistaeb90b782008-08-16 14:44:07 +00007588- Issue #2776: fixed small issue when handling an URL with double slash
7589 after a 302 response in the case of not going through a proxy.
7590
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007591- Issue #2676: in the email package, content-type parsing was hanging on
7592 pathological input because of quadratic or exponential behaviour of a
7593 regular expression.
7594
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007595- Issue #3476: binary buffered reading through the new "io" library is now
7596 thread-safe.
7597
Brett Cannonbf3157b2008-08-14 05:00:03 +00007598- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7599 since mimetools itself is deprecated. Because modules are cached, all
7600 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7601
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007602- Issue #3134: shutil referenced undefined WindowsError symbol.
7603
Robert Schuppenies14646332008-08-10 11:01:53 +00007604- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7605 menu entries were not deleted.
7606
Brett Cannon83e81842008-08-09 23:30:55 +00007607- Copied the implementation of reduce() to _functools.reduce() to have a
7608 version that did not raise a DeprecationWarning under -3.
7609
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007610- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7611 a MemoryError rather than silently stop the iteration.
7612
Guido van Rossum59ce9012008-08-09 14:55:34 +00007613- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7614 to _sre.compile() will now be rejected. This should not affect anybody
7615 since the re.compile() function never generates invalid re-bytecode.
7616
Skip Montanaroa032bf42008-08-08 22:52:51 +00007617- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7618 upon first access it can be automatically initialized from the csv file if
7619 it wasn't initialized during instantiation.
7620
Brett Cannon3aa2a492008-08-06 22:28:09 +00007621- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7622 the reload() built-in has been removed.
7623
Brett Cannon7e30b672008-08-04 21:52:25 +00007624- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007625 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007636 asking for a specific length. This problem only affected files opened
7637 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007638

7663 file name rather than a ZipInfo instance, so files are extracted with
7664 mode 0600 rather than 000 under Unix.
7665
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007666- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7667 argument in python 2.5, this broke code that subclassed Popen to include its
7668 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7682 coverage of the lookup process for special methods. The disclaimers
7683 regarding lack of coverage of new-style classes have also been
7684 removed, since the coverage is now fairly reasonable.

7694
Georg Brandl3e483f62008-07-16 22:57:41 +00007695- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7696 its methods now allow for items objects that can be converted to
7697 an integer using operator.index().
7698
Mark Dickinson64b7e502008-07-16 09:40:03 +00007699- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7700 produced a ValueError instead of giving the correct float.
7701
Eric Smitha5fa5a22008-07-16 00:11:49 +00007702- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7703 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7704
Mark Dickinson7103aa42008-07-15 19:08:33 +00007705- Issue #3008: the float type has a new instance method 'float.hex'

7708
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007709- Issue #2235: __hash__ is once again inherited by default. To allow
7710 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00007716- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7717 the parent module cannot be found while performing an absolute import.
7718 This means that an incorrectly defined __package__ attribute will
7719 now only prevent relative imports in that module rather than causing
7720 all imports from that module to fail.

7735 arguments are now treated identically, making the behaviour easier
7736 to describe and understand. For example, slice(None, -10,
7737 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7738 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7739 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00008191 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008192
8193 This is controlled by the configure argument ``--with-universal-archs``:

8239 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Issue #1631171: Re-implement the 'warnings' module in C (the
8253 original Python code has been kept as backup). This will allow for
8254 using the 'warning's machinery in such places as the parser where
8255 use of pure Python code is not possible. Both the ``showarning()``
8256 and ``formatwarning()`` gain an optional 'line' argument which is
8257 not called by default for backwards-compatibility reasons. Setting
8258 ``warnings.showwarning()`` to an implementation that lacks support
8259 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008322- Issue #2550: The approach used by client/server code for obtaining
8323 ports to listen on in network-oriented tests has been refined in an
8324 effort to facilitate running multiple instances of the entire
8325 regression test suite in parallel without issue.
8326 test_support.bind_port() has been fixed such that it will always
8327 return a unique port -- which wasn't always the case with the
8328 previous implementation, especially if socket options had been set
8329 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8330 new implementation of bind_port() will actually raise an exception
8331 if it is passed an AF_INET/SOCK_STREAM socket with either the
8332 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8333 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8334 the socket it's been passed. This currently only applies to
8335 Windows. This option prevents any other sockets from binding to the
8336 host/port we've bound to, thus removing the possibility of the
8337 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8338 when a second SOCK_STREAM socket binds and accepts to a host/port
8339 that's already been bound by another socket. The optional preferred
8340 port parameter to bind_port() has been removed. Under no
8341 circumstances should tests be hard coding ports!
8342
8343 test_support.find_unused_port() has also been introduced, which will
8344 pass a temporary socket object to bind_port() in order to obtain an
8345 unused port. The temporary socket object is then closed and
8346 deleted, and the port is returned. This method should only be used
8347 for obtaining an unused port in order to pass to an external program
8348 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8349 a parameter to a server-oriented class that doesn't give you direct
8350 access to the underlying socket used.
8351
8352 Finally, test_support.HOST has been introduced, which should be used
8353 for the host argument of any relevant socket calls (i.e. bind and
8354 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008355
8356 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008357 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008358 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8359 test_asynchat and test_socket_ssl.
8360
Georg Brandl3ee81df2008-05-17 18:14:43 +00008361 It is now possible for multiple instances of the regression test
8362 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008641- Added the future_builtins module, which contains hex() and oct().
8642 These are the PEP 3127 version of these functions, designed to be
8643 compatible with the hex() and oct() builtins from Python 3.0. They
8644 differ slightly in their output formats from the existing, unchanged
8645 Python 2.6 builtins. The expected usage of the future_builtins
8646 module is:
8647 from future_builtins import hex, oct
8648
Eric Smith7ef40bf2008-02-20 23:34:22 +00008649- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8650 exponents for exponents with absolute value < 100. Follows C99
8651 standard. This is a change on Windows, which would use 3 digits.
8652 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8653 so that any alterations it does to the resulting string will be
8654 available in stringlib/formatter.h (for float.__format__).
8655
Eric Smith5a3c1352008-02-19 13:21:56 +00008656- Implemented PEP 3101, Advanced String Formatting. This adds a new
8657 builtin format(); a format() method for str and unicode; a
8658 __format__() method to object, str, unicode, int, long, float, and
8659 datetime; the class string.Formatter; and the C API
8660 PyObject_Format().
8661
Georg Brandl3ee81df2008-05-17 18:14:43 +00008662- Fixed several potential crashes, all caused by specially crafted
8663 __del__ methods exploiting objects in temporarily inconsistent
8664 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008665
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008666- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008667 prevent a possible crash: an Abstract Base Class would try to access
8668 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008669

Georg Brandl3ee81df2008-05-17 18:14:43 +00008673- Clear all free lists during a gc.collect() of the highest generation
8674 in order to allow pymalloc to free more arenas. Python may give back
8675 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008676
Georg Brandl3ee81df2008-05-17 18:14:43 +00008677- Issue #2045: Fix an infinite recursion triggered when printing a
8678 subclass of collections.defaultdict, if its default_factory is set
8679 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008680
Christian Heimesf75dbef2008-02-08 00:11:31 +00008681- Fixed a minor memory leak in dictobject.c. The content of the free
8682 list was not freed on interpreter shutdown.
8683
Georg Brandl21e99f42010-03-07 15:23:59 +00008684- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00008686
Georg Brandl3ee81df2008-05-17 18:14:43 +00008687- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8688 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008689 to compact the internal free lists of pre-allocted ints and floats.
8690
Georg Brandl3ee81df2008-05-17 18:14:43 +00008691- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8692 calls. Python expected the return type int but the fork familie
8693 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008694
Georg Brandl3ee81df2008-05-17 18:14:43 +00008695- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008707- Patch #1473257: generator objects gain a gi_code attribute. This is
8708 the same object as the func_code attribute of the function that
8709 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008710
Georg Brandl3ee81df2008-05-17 18:14:43 +00008711- Issue #1920: "while 0" statements were completely removed by the
8712 compiler, even in the presence of an "else" clause, which is
8713 supposed to be run when the condition is false. Now the compiler
8714 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008715
Guido van Rossumeead05f2008-01-24 18:21:02 +00008716- A few crashers fixed: weakref_in_del.py (issue #1377858);
8717 loosing_dict_ref.py (issue #1303614, test67.py);
8718 borrowed_ref_[34].py (not in tracker).
8719
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008720- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008721 suppressed while an extension is loaded by calling SetErrorMode in

8723
Georg Brandl3ee81df2008-05-17 18:14:43 +00008724- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008725 several extension methods and modules do not work without unicode
8726 support.
8727
Georg Brandl26543b12008-01-21 18:36:51 +00008728- Issue #1882: when compiling code from a string, encoding cookies in the
8729 second line of code were not always recognized correctly.
8730
Georg Brandl14404b62008-01-19 19:27:05 +00008731- Issue #1679: "0x" was taken as a valid integer literal.
8732
Georg Brandl6caad7d2008-01-26 14:19:22 +00008733- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008734 added.
8735
Christian Heimesc94e2b52008-01-14 04:13:37 +00008736- sys.float_info / PyFloat_GetInfo: The floating point information
8737 object was converted from a dict to a specialized structseq object.
8738
Georg Brandl3ee81df2008-05-17 18:14:43 +00008739- Patch #1816: Added sys.flags structseq. It exposes the status of
8740 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008741
Georg Brandl3ee81df2008-05-17 18:14:43 +00008742- Objects/structseq.c: Implemented new structseq representation. The

Christian Heimes0a8143f2007-12-18 23:22:54 +00008770
Georg Brandl3ee81df2008-05-17 18:14:43 +00008771- Compiler now generates simpler and faster code for dictionary
8772 literals. The oparg for BUILD_MAP now indicates an estimated
8773 dictionary size. There is a new opcode, STORE_MAP, for adding
8774 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008819 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8820 automatically shifts from ints to longs.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008822- Issue #1686386: Tuple's tp_repr did not take into account the
8823 possibility of having a self-referential tuple, which is possible
8824 from C code. Nor did object's tp_str consider that a type's tp_str
8825 could do something that could lead to an inifinite recursion.
8826 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8827 issues.

8830 'print' statement to write to a file since the GIL was not released
8831 as needed. Now PyObject_Print() does the right thing along with
8832 various tp_print implementations of the built-in types and those in
8833 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008843 PyObject_Call() never calling back out to Python code to trigger
8844 recursion depth updates/checks. Required the creation of a static

8894
Guido van Rossum143b5642007-03-23 04:58:42 +00008895- Bug #1683368: The object.__init__() and object.__new__() methods are
8896 now stricter in rejecting excess arguments. The only time when
8897 either allows excess arguments is when it is not overridden and the
8898 other one is. For backwards compatibility, when both are
8899 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008900 warning later). Also, type.__init__() insists on the same signature
8901 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008903- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8904 object to complex using its __complex__() method before falling back
8905 to the __float__() method. Therefore, the functions in the cmath
8906 module now can operate on objects that define a __complex__()
8907 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008925- Bug #1678647: write a newline after printing an exception in any
8926 case, even when converting the value to a string failed.
8927
Georg Brandl871f1bc2007-03-12 13:17:36 +00008928- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008929 its argument, if it exists. If not, it will work like before. This
8930 allows customizing the output of dir() in the presence of a
8931 __getattr__().

8941 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008942
Georg Brandlaa2321b2007-03-07 00:40:28 +00008943- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008944 makes the filenames the warning module prints much more sensible
8945 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008958- Patch #1674228: when assigning a slice (old-style), check for the
8959 sq_ass_slice instead of the sq_slice slot.
8960
Georg Brandl3ee81df2008-05-17 18:14:43 +00008961- When printing an unraisable error, don't print exceptions. before

Georg Brandl92a6bae2007-03-13 17:43:32 +00009529- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009530 are set for invalid interpolation sequences that would lead to

9864 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009865
Georg Brandl3ee81df2008-05-17 18:14:43 +00009866- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9867 with RFC 3207 and forgets any knowledge obtained from the server not
9868 obtained from the TLS negotiation itself. Patch contributed by Bill
9869 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009870
Georg Brandl3ee81df2008-05-17 18:14:43 +00009871- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009872 that the SMTP.starttls() caller no longer needs to call ehlo()
9873 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009874 does not claim to support starttls. Adds the
9875 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9876 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009918- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009919 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00009930- itertools.chain() now has an alternate constructor,

9956 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9957 silently miscode subclasses of those types. Now, it raises a
9958 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009959

Georg Brandl3ee81df2008-05-17 18:14:43 +00009974 time so that opening a database previously created with the DB_DUP
9975 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9976 opens. Specifically: dictionary assignment to a DB object will
9977 replace all values for a given key when the database allows
9978 duplicate values. DB users should use DB.put(k, v) when they want
9979 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009980

9986 characters with ASCII value less than 32. Also, it correctly quotes
9987 dots only if they occur on a single line, as opposed to the previous
9988 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010264- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +000010265 periodic threadstate and signal checking in tight loops. By
10266 default, this option is turned-off. It should only be enabled in
10267 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +000010268

10318
Georg Brandl3ee81df2008-05-17 18:14:43 +000010319- Unified naming convention for free lists and their limits. All free
10320 lists in Object/ are named ``free_list``, the counter ``numfree``
10321 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10322 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010323
Georg Brandl3ee81df2008-05-17 18:14:43 +000010324- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10325 to ``PyTuple_SetItem``, it can be used to populate a brand new
10326 frozenset; but it does not steal a reference to the added item.

10340 of w# format code incorrectly truncated the length to an int, even
10341 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10342 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010343

10363 (relevant to strings and sequences of more than 2**31 items).
10364
10365- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10366 outside of pystate.c and should not be necessary.
10367
Georg Brandl3ee81df2008-05-17 18:14:43 +000010368- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10369 absolute imports. In earlier versions they might have used relative
10370 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010371
Georg Brandl3ee81df2008-05-17 18:14:43 +000010372- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10373 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010374

Georg Brandl3ee81df2008-05-17 18:14:43 +000010398- Removed the macfs module. It had been deprecated since Python 2.5.
10399 This lead to the deprecation of macostools.touched() as it relied
10400 solely on macfs and was a no-op under OS X.
