943
944- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
945 and later systems as is currently done for Python 3.x installers.
946 For 2.7.7 only, we will provide three installers:
947 the legacy deprecated 10.3+ 32-bit-only format;
948 the newer 10.5+ 32-bit-only format;
949 and the unchanged 10.6+ 64-/32-bit format.
950 Although binary installers will no longer be available from
951 python.org as of 2.7.8, it will still be possible to build from
952 source on 10.3.9 and 10.4 systems if necessary.

Ned Deily8e60f6e2013-05-30 00:14:29 -07001268- Issue #18098: The deprecated OS X Build Applet.app fails to build on

1276 64-bit/32-bit installer for 10.6+. It is no longer necessary
1277 to install a third-party version of Tcl/Tk 8.5 to work around the
1278 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
1279 and later releases.

1282 of OPT for special build options. By setting OPT, some compiler-specific
1283 options like -fwrapv were overridden and thus not used, which could result
1284 in broken interpreters when building with clang.

2335 32-bit-only installer Pythons on systems with Xcode 4 (currently
2336 OS X 10.8, 10.7, and optionally 10.6).
2337 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2338 * Since Xcode 4 removes ppc support, extension module builds now
2339 check for ppc compiler support and by default remove ppc and
2340 ppc64 archs when they are not available.
2341 * Extension module builds now revert to using system installed
2342 headers and libs (/usr and /System/Library) if the SDK used
2343 to build the interpreter is not installed or has moved.
2344 * Try to avoid building extension modules with deprecated
2345 and problematic Apple llvm-gcc compiler. If original compiler
2346 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002710- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2711 int.__pow__. These overflow checks were causing int.__pow__ to produce
2712 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002713 compiler optimizing the check away. Also fix similar overflow checks
2714 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2715 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002783- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002784 has left two versions of customize_compiler, the original in
2785 distutils.sysconfig and another copy in distutils.ccompiler, with some

2788 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002790- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2791 Distutils-based packages with C extension modules may fail because
2792 Apple has removed gcc-4.2, the version used to build python.org
2793 64-bit/32-bit Pythons. If the user does not explicitly override
2794 the default C compiler by setting the CC environment variable,
2795 Distutils will now attempt to compile extension modules with clang
2796 if gcc-4.2 is required but not found. Also as a convenience, if
2797 the user does explicitly set CC, substitute its value as the default
2798 compiler in the Distutils LDSHARED configuration variable for OS X.
2799 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2800 SDK, neither of which are available in Xcode 4. This change does not
2801 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003051- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3052 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3053 interpreter process. This could cause failures in non-Distutils subprocesses
3054 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003055 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003056 deployment target only in the environment of each build subprocess. It is
3057 still possible to globally override the default by setting
3058 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3059 greater or equal to the default value, the value with which the interpreter
3060 was built.

3089 updating the check interval, so if the user decreases the check interval,
3090 the ticker doesn't have to wind down to zero from the old starting point
3091 before the new interval takes effect. And if the user increases the
3092 interval, it makes sure the new limit takes effect right away rather have an
3093 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00004090- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4091 This prevents user-created self-referencing ordered dictionaries from
4092 becoming permanently uncollectable GC garbage. The downside is that
4093 removing __del__ means that the internal doubly-linked list has to wait for
4094 GC collection rather than freeing memory immediately when the refcnt drops
4095 to zero.

4103 to fetch the original errno, or to filter timeout errors. Now the
4104 original error is re-raised.

4125
R. David Murray7c4bf552010-08-25 01:45:57 +00004126- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4127 character years even if the message contains RFC822 two character years.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004553- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4554 start byte and the continuation byte(s) are now considered invalid, instead
4555 of the number of bytes specified by the start byte.
4556 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4557 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4558 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004567- Issue #8748: Fix two issues with comparisons between complex and integer
4568 objects. (1) The comparison could incorrectly return True in some cases
4569 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4570 (2) The comparison raised an OverflowError for large integers, leading
4571 to unpredictable exceptions when combining integers and complex objects

Georg Brandlfee0f442010-05-22 21:26:21 +00004954- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4955 with a non-empty format string. This is an effort to future-proof user
4956 code. If a derived class does not currently implement __format__ but later
4957 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004958 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004959 Python 3.3 and it will be an error in Python 3.4.

5549-----------------
5550
Georg Brandlba83f822010-03-14 09:50:54 +00005551- The ``__complex__()`` method is now looked up on the class of instances to
5552 make it consistent with other special methods.

5556
Mark Dickinson1b34d252010-01-01 17:27:30 +00005557- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005558 DeprecationWarning when passed a float argument where an integer was expected.
5559 These functions and methods now raise TypeError instead. The majority of the
5560 effects of this change are in the extension modules, but some core functions
5561 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5562 and many unicode/str methods.

5576 of integers: the result of a/b is now correctly rounded for ints a and b (at
5577 least on IEEE 754 platforms), and in particular does not depend on the
5578 internal representation of a long.

5586
Georg Brandlba83f822010-03-14 09:50:54 +00005587 These executables now work properly with the arch(1) command: ``arch -ppc
5588 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005744- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5745 decimal string that's guaranteed to round back to x under correct rounding
5746 (with round-half-to-even rounding mode). Previously it gave a string based on
5747 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5748 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5749 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005750
Georg Brandlba83f822010-03-14 09:50:54 +00005751- Issue #7117: On almost all platforms: float-to-string and string-to-float
5752 conversions within Python are now correctly rounded. Places these conversions
5753 occur include: str for floats and complex numbers; the float and complex
5754 constructors; old-style and new-style numeric formatting; serialization and
5755 deserialization of floats and complex numbers using marshal, pickle and json;
5756 parsing of float and imaginary literals in Python code; Decimal-to-float
5757 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005758
Georg Brandlba83f822010-03-14 09:50:54 +00005759 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5760 providing correctly-rounded strtod and dtoa C functions. This code is
5761 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5762 the C compiler. There may be a small number of platforms on which correct
5763 operation of this code cannot be guaranteed, so the code is not used: notably,
5764 this applies to platforms where the C double format is not IEEE 754 binary64,
5765 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5766 and Python's configure script is unable to determine how to change the FPU
5767 precision. On these platforms conversions use the platform strtod and dtoa,
5768 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005770- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5771 uses the correctly-rounded string <-> float conversions described above (when
5772 available), and so produces correctly rounded results that will display nicely
5773 under the float repr. There are two related small changes: (1) round now
5774 accepts any class with an ``__index__()`` method for its second argument (but
5775 no longer accepts floats for the second argument), and (2) an excessively
5776 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5777 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005924- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5925 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5926 but with at least one decimal point and with a default precision
5927 of 12. Previously, the behavior the same but with a default precision of 6.
5928 This more closely matches ``str()``, and reduces surprises when adding
5929 alignment flags to the empty presentation type. This also affects the new
5930 complex.__format__ in the same way.

6121
Georg Brandlba83f822010-03-14 09:50:54 +00006122- Issue #3689: The list reversed iterator now supports __length_hint__ instead

6127
Georg Brandlba83f822010-03-14 09:50:54 +00006128- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6129 file objects with closefd=False. The file descriptor is still kept open but
6130 the file object behaves like a closed file. The ``FileIO`` object also got a
6131 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006151- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00006154- On windows, ``os.chdir()`` given unicode was not working if
6155 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6156 this code path is really executed because I cannot move to such directory on
6157 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006159- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6160 element is temporarily replaced with an equivalent frozenset. But the
6161 eventual KeyError would always report the empty ``frozenset()`` as the missing
6162 key. Now it correctly refers to the initial element.

6181
Walter Dörwalded960ac2009-05-03 22:36:33 +00006182- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6183 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6184 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6185 of using the replace error handler in PyUnicode_DecodeUTF8().
6186
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006187- Issue #3739: The unicode-internal encoder now reports the number of characters
6188 consumed like any other encoder (instead of the number of bytes).
6189
Georg Brandlba83f822010-03-14 09:50:54 +00006190- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6191 allocator will be automatically disabled when running under Valgrind. This
6192 gives improved memory leak detection when running under Valgrind, while taking
6193 advantage of pymalloc at other times.

7583
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007584- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7585 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7586 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7587 ``printf`` function, whereas PyString_FromFormat has an independent
7588 implementation and uses "%zd" on all platforms for size_t values.
7589 This makes a difference on win64, where ``printf`` needs "%Id" to display
7590 64bit values.

7596 object; previously an int would be returned for small values. the __long__
7597 method is allowed to return either an int or a long, but the behaviour of
7598 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007607 was correctly parsed but parsing of subsequent arguments failed.
7608
Vinay Sajip35e3b032008-09-01 14:33:59 +00007609- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007610 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7611 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7612 when given a tuple of classes as second argument, were looking up
7613 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7614 type object.
7615

7759-----------------
7760
Guido van Rossumf8402962008-08-20 15:01:50 +00007761- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7762 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7763 extensions do not automatically benefit from the class attribute
7764 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7765 to their tp_flags field if they care. This is a backwards
7766 compatibility feature; in 3.0, all types will use the cache by
7767 default.
7768
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007769- Keyword arguments can now follow starred arguments. (``f(a, *args,
7770 keyword=23)`` is now valid syntax.)
7771
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007772- ctypes function pointers that are COM methods have a boolean True
7773 value again.

Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007785- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7786 (64bit Unix, for example), unichr() would truncate its argument and return
7787 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007791- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7792 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7793
Antoine Pitrou92f82162008-07-25 22:22:08 +00007794- Issue #1819: function calls with several named parameters are now on
7795 average 35% faster (as measured by pybench).
7796
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007797- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7798 the python debugger steps into a class statement: the free variables (local
7799 variables defined in an outer scope) would be deleted from the outer scope.
7800
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007801- Issue #2620: Overflow checking when allocating or reallocating memory
7802 was not always being done properly in some python types and extension
7803 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7804 all been updated to perform better checks and places in the code that
7805 would previously leak memory on the error path when such an allocation
7806 failed have been fixed.

7812
Benjamin Petersone977ad42008-08-20 01:42:01 +00007813- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7814 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7815
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007816- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7817 version reported by these tools does not necessarily follow the python
7818 version numbering scheme, so the module is less strict when parsing it.
7819
Nick Coghlanf70385a2008-08-18 12:42:46 +00007820- Issue #2235: Added Py3k warnings for types which will become unhashable
7821 under the stricter __hash__ inheritance rules in 3.0. Several types
7822 which did not meet the rules for hash invariants and were already
7823 unhashable in 3.0 have now been explicitly flagged as unhashable in
7824 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7825 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7826
Brett Cannon88f801d2008-08-18 00:46:22 +00007827- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7828 imported into the module but exposed as part of the module's API.
7829

7835
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007836- Issue #3575: Incremental decoder's decode function now takes bytearray
7837 by using 's*' instead of 't#'.
7838
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007839- Issue #2222: Fixed reference leak when occurred os.rename()

7849 after a 302 response in the case of not going through a proxy.
7850
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007851- Issue #2676: in the email package, content-type parsing was hanging on
7852 pathological input because of quadratic or exponential behaviour of a
7853 regular expression.
7854
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007855- Issue #3476: binary buffered reading through the new "io" library is now
7856 thread-safe.
7857
Brett Cannonbf3157b2008-08-14 05:00:03 +00007858- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7859 since mimetools itself is deprecated. Because modules are cached, all
7860 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7861
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007862- Issue #3134: shutil referenced undefined WindowsError symbol.

7865 menu entries were not deleted.
7866
Brett Cannon83e81842008-08-09 23:30:55 +00007867- Copied the implementation of reduce() to _functools.reduce() to have a

7869
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007870- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7871 a MemoryError rather than silently stop the iteration.
7872
Guido van Rossum59ce9012008-08-09 14:55:34 +00007873- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7874 to _sre.compile() will now be rejected. This should not affect anybody
7875 since the re.compile() function never generates invalid re-bytecode.
7876
Skip Montanaroa032bf42008-08-08 22:52:51 +00007877- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7878 upon first access it can be automatically initialized from the csv file if
7879 it wasn't initialized during instantiation.
7880
Brett Cannon3aa2a492008-08-06 22:28:09 +00007881- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7882 the reload() built-in has been removed.
7883
Brett Cannon7e30b672008-08-04 21:52:25 +00007884- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007885 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7893 raised an AttributeError.
7894
Benjamin Peterson01a24322008-07-28 23:35:27 +00007895- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007896 asking for a specific length. This problem only affected files opened
7897 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007898

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007922- Issue #3394: zipfile.writestr sets external attributes when passed a
7923 file name rather than a ZipInfo instance, so files are extracted with
7924 mode 0600 rather than 000 under Unix.
7925
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007926- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7927 argument in python 2.5, this broke code that subclassed Popen to include its
7928 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007938- Issue #2235: the C API function PyObject_HashNotImplemented and its
7939 interaction with the tp_hash slot (added in 2.6b2) are now documented
7940
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007941- Issue #643841: The language reference now provides more detailed
7942 coverage of the lookup process for special methods. The disclaimers
7943 regarding lack of coverage of new-style classes have also been
7944 removed, since the coverage is now fairly reasonable.

7948================================
7949
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007950*Release date: 17-Jul-2008*
7951
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007952Core and Builtins
7953-----------------
7954
Georg Brandl3e483f62008-07-16 22:57:41 +00007955- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7956 its methods now allow for items objects that can be converted to
7957 an integer using operator.index().
7958
Mark Dickinson64b7e502008-07-16 09:40:03 +00007959- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7960 produced a ValueError instead of giving the correct float.
7961
Eric Smitha5fa5a22008-07-16 00:11:49 +00007962- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7963 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7964
Mark Dickinson7103aa42008-07-15 19:08:33 +00007965- Issue #3008: the float type has a new instance method 'float.hex'
7966 and a new class method 'float.fromhex' to convert floating-point
7967 numbers to and from hexadecimal strings, respectively.
7968
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007969- Issue #2235: __hash__ is once again inherited by default. To allow
7970 collections.Hashable to remain meaningful in the presence of the
7971 default hash implementation (object.__hash__), it is now possible
7972 to explicit block inheritance of hash by setting __hash__=None at
7973 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7974 level.
7975
Nick Coghlanb028f502008-07-13 14:52:36 +00007976- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7977 the parent module cannot be found while performing an absolute import.
7978 This means that an incorrectly defined __package__ attribute will
7979 now only prevent relative imports in that module rather than causing
7980 all imports from that module to fail.
7981
Nick Coghlan14ff9942008-07-08 14:21:42 +00007982- Issue #2517: Allow unicode messages in Exceptions again by correctly
7983 bypassing the instance dictionary when looking up __unicode__ on
7984 new-style classes.
7985
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007986- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7987 set to a custom object whose write() method happens to install
7988 another file in sys.stdout.
7989
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007990- Issue #3088: Corrected a race condition in classes derived from
7991 threading.local: the first member set by a thread could be saved in
7992 another thread's dictionary.
7993
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007994- Issue #3004: Minor change to slice.indices(): the start and stop
7995 arguments are now treated identically, making the behaviour easier
7996 to describe and understand. For example, slice(None, -10,
7997 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7998 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7999 10, -1).
8000
Georg Brandl278fc502008-07-19 12:46:12 +00008001- Issue #3219: Calling a function with repeated keyword arguments,
8002 f(a=2, a=23), would not cause a syntax error. This was a regression
8003 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008004
Georg Brandl278fc502008-07-19 12:46:12 +00008005- Issue #2862: Make int and float freelist management consistent with
8006 other freelists. Changes their CompactFreeList apis into
8007 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008008

8010-------
8011
Thomas Heller57adf222008-08-14 19:10:48 +00008012- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8013 api functions without holding the GIL, which could lead to a fatal
8014 error when they failed.
8015
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008016- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00008024- Issue #3125: Remove copy_reg in multiprocessing and replace it with
8025 ForkingPickler.register() to resolve conflict with ctypes.
8026
Vinay Sajip51e65192008-07-18 09:01:10 +00008027- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00008029- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8030 a valid dlerror() message.
8031
Thomas Heller2bad6572008-07-15 17:19:50 +00008032- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8033 incomplete structure was created.
8034

8038
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008039- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008040
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008041- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8042 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008043 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008044 content-length. The problem had been corrected in the 2.4 branch, but never
8045 merged into trunk.
8046
Georg Brandle78fbcc2008-07-05 10:13:36 +00008047- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008058 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00008059
Nick Coghlanc060b0e2008-07-02 13:09:19 +00008060- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8061 handling is now the same as that of other special attributes like __name__).
8062
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008063- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
8064 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008451 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008452
8453 This is controlled by the configure argument ``--with-universal-archs``:
8454
8455 - ``--with-universal-archs=all``: install 4-way universal
8456
8457 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8458
8459 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8460
8461 This option should be used in combination with ``--enable-universalsdk=``.
8462
8463 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 +00008512- Issue #1631171: Re-implement the 'warnings' module in C (the
8513 original Python code has been kept as backup). This will allow for
8514 using the 'warning's machinery in such places as the parser where
8515 use of pure Python code is not possible. Both the ``showarning()``
8516 and ``formatwarning()`` gain an optional 'line' argument which is
8517 not called by default for backwards-compatibility reasons. Setting
8518 ``warnings.showwarning()`` to an implementation that lacks support
8519 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008582- Issue #2550: The approach used by client/server code for obtaining
8583 ports to listen on in network-oriented tests has been refined in an
8584 effort to facilitate running multiple instances of the entire
8585 regression test suite in parallel without issue.
8586 test_support.bind_port() has been fixed such that it will always
8587 return a unique port -- which wasn't always the case with the
8588 previous implementation, especially if socket options had been set
8589 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8590 new implementation of bind_port() will actually raise an exception
8591 if it is passed an AF_INET/SOCK_STREAM socket with either the
8592 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8593 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8594 the socket it's been passed. This currently only applies to
8595 Windows. This option prevents any other sockets from binding to the
8596 host/port we've bound to, thus removing the possibility of the
8597 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8598 when a second SOCK_STREAM socket binds and accepts to a host/port
8599 that's already been bound by another socket. The optional preferred
8600 port parameter to bind_port() has been removed. Under no
8601 circumstances should tests be hard coding ports!
8602
8603 test_support.find_unused_port() has also been introduced, which will
8604 pass a temporary socket object to bind_port() in order to obtain an
8605 unused port. The temporary socket object is then closed and
8606 deleted, and the port is returned. This method should only be used
8607 for obtaining an unused port in order to pass to an external program
8608 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8609 a parameter to a server-oriented class that doesn't give you direct
8610 access to the underlying socket used.
8611
8612 Finally, test_support.HOST has been introduced, which should be used
8613 for the host argument of any relevant socket calls (i.e. bind and
8614 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008615
8616 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008617 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008618 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8619 test_asynchat and test_socket_ssl.
8620
Georg Brandl3ee81df2008-05-17 18:14:43 +00008621 It is now possible for multiple instances of the regression test
8622 suite to run in parallel without issue.

8888Core and builtins
8889-----------------
8890
Fred Drakea8ee94b2008-03-01 02:45:07 +00008891- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008892 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008893
Georg Brandlad61bc82008-02-23 15:11:18 +00008894- Issue #2067: file.__exit__() now calls subclasses' close() method.
8895
8896- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008897
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008898- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008899 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008900
Eric Smitha73fbe72008-02-23 03:09:44 +00008901- Added the future_builtins module, which contains hex() and oct().
8902 These are the PEP 3127 version of these functions, designed to be
8903 compatible with the hex() and oct() builtins from Python 3.0. They
8904 differ slightly in their output formats from the existing, unchanged
8905 Python 2.6 builtins. The expected usage of the future_builtins
8906 module is:
8907 from future_builtins import hex, oct
8908
Eric Smith7ef40bf2008-02-20 23:34:22 +00008909- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8910 exponents for exponents with absolute value < 100. Follows C99
8911 standard. This is a change on Windows, which would use 3 digits.
8912 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8913 so that any alterations it does to the resulting string will be
8914 available in stringlib/formatter.h (for float.__format__).
8915
Eric Smith5a3c1352008-02-19 13:21:56 +00008916- Implemented PEP 3101, Advanced String Formatting. This adds a new
8917 builtin format(); a format() method for str and unicode; a
8918 __format__() method to object, str, unicode, int, long, float, and
8919 datetime; the class string.Formatter; and the C API
8920 PyObject_Format().
8921
Georg Brandl3ee81df2008-05-17 18:14:43 +00008922- Fixed several potential crashes, all caused by specially crafted
8923 __del__ methods exploiting objects in temporarily inconsistent
8924 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008925
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008926- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008927 prevent a possible crash: an Abstract Base Class would try to access
8928 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008929
Georg Brandl3ee81df2008-05-17 18:14:43 +00008930- Fixed repr() and str() of complex numbers with infinity or nan as
8931 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008932
Georg Brandl3ee81df2008-05-17 18:14:43 +00008933- Clear all free lists during a gc.collect() of the highest generation
8934 in order to allow pymalloc to free more arenas. Python may give back
8935 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008936
Georg Brandl3ee81df2008-05-17 18:14:43 +00008937- Issue #2045: Fix an infinite recursion triggered when printing a
8938 subclass of collections.defaultdict, if its default_factory is set
8939 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008940
Christian Heimesf75dbef2008-02-08 00:11:31 +00008941- Fixed a minor memory leak in dictobject.c. The content of the free
8942 list was not freed on interpreter shutdown.
8943
Georg Brandl21e99f42010-03-07 15:23:59 +00008944- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008945 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008946
Georg Brandl3ee81df2008-05-17 18:14:43 +00008947- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8948 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008949 to compact the internal free lists of pre-allocted ints and floats.
8950
Georg Brandl3ee81df2008-05-17 18:14:43 +00008951- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8952 calls. Python expected the return type int but the fork familie
8953 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008954
Georg Brandl3ee81df2008-05-17 18:14:43 +00008955- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8956 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008957
Georg Brandl3ee81df2008-05-17 18:14:43 +00008958- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8959 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008960
Georg Brandl3ee81df2008-05-17 18:14:43 +00008961- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8962 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008963
Georg Brandl3ee81df2008-05-17 18:14:43 +00008964- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8965 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008966
Georg Brandl3ee81df2008-05-17 18:14:43 +00008967- Patch #1473257: generator objects gain a gi_code attribute. This is
8968 the same object as the func_code attribute of the function that
8969 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008970
Georg Brandl3ee81df2008-05-17 18:14:43 +00008971- Issue #1920: "while 0" statements were completely removed by the
8972 compiler, even in the presence of an "else" clause, which is
8973 supposed to be run when the condition is false. Now the compiler
8974 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008975
Guido van Rossumeead05f2008-01-24 18:21:02 +00008976- A few crashers fixed: weakref_in_del.py (issue #1377858);
8977 loosing_dict_ref.py (issue #1303614, test67.py);
8978 borrowed_ref_[34].py (not in tracker).
8979
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008980- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008981 suppressed while an extension is loaded by calling SetErrorMode in
8982 dynload_win.c. The error is still reported properly.
8983
Georg Brandl3ee81df2008-05-17 18:14:43 +00008984- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008985 several extension methods and modules do not work without unicode
8986 support.
8987
Georg Brandl26543b12008-01-21 18:36:51 +00008988- Issue #1882: when compiling code from a string, encoding cookies in the
8989 second line of code were not always recognized correctly.
8990
Georg Brandl14404b62008-01-19 19:27:05 +00008991- Issue #1679: "0x" was taken as a valid integer literal.
8992
Georg Brandl6caad7d2008-01-26 14:19:22 +00008993- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008994 added.
8995
Christian Heimesc94e2b52008-01-14 04:13:37 +00008996- sys.float_info / PyFloat_GetInfo: The floating point information
8997 object was converted from a dict to a specialized structseq object.
8998
Georg Brandl3ee81df2008-05-17 18:14:43 +00008999- Patch #1816: Added sys.flags structseq. It exposes the status of
9000 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009001
Georg Brandl3ee81df2008-05-17 18:14:43 +00009002- Objects/structseq.c: Implemented new structseq representation. The
9003 patch makes structseqs (e.g. the return value of os.stat) more
9004 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009005
Georg Brandl3ee81df2008-05-17 18:14:43 +00009006- Patch #1700288: added a type attribute cache that caches method
9007 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009008
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009009- Bug #1776: __import__() no longer accepts filenames on any platform.
9010 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009011
Georg Brandlaed6c662008-01-07 17:25:53 +00009012- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9013
Georg Brandl3ee81df2008-05-17 18:14:43 +00009014- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9015 envvar and sys.dont_write_bytecode attribute. All these can be set
9016 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009017
Georg Brandl3ee81df2008-05-17 18:14:43 +00009018- Improve some exception messages when Windows fails to load an
9019 extension module. Now we get for example '%1 is not a valid Win32
9020 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009021
Georg Brandl3ee81df2008-05-17 18:14:43 +00009022- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009024- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9025 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009026
Christian Heimes0a8143f2007-12-18 23:22:54 +00009027- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009028 and INF. float("nan"), float("inf") and float("-inf") now work on
9029 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009030
Georg Brandl3ee81df2008-05-17 18:14:43 +00009031- Compiler now generates simpler and faster code for dictionary
9032 literals. The oparg for BUILD_MAP now indicates an estimated
9033 dictionary size. There is a new opcode, STORE_MAP, for adding
9034 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009035
Georg Brandl3ee81df2008-05-17 18:14:43 +00009036- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009041- Issue #1538: Avoid copying string in split/rsplit if the split char
9042 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009043
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009044- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009045 SystemError.
9046
Nick Coghlanef01d822007-12-03 12:55:17 +00009047- PEP 366: Allow explicit relative imports when executing modules

9049 __package__ attribute.
9050
Georg Brandl3ee81df2008-05-17 18:14:43 +00009051- Issue #1402: Fix a crash on exit, when another thread is still
9052 running, and if the deallocation of its frames somehow calls the
9053 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009054

9064 file can now be directly executed by passing their name to the
9065 interpreter. The directory/zipfile is automatically inserted as the
9066 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009067
Georg Brandl3ee81df2008-05-17 18:14:43 +00009068- Issue #1265: Fix a problem with sys.settrace, if the tracing
9069 function uses a generator expression when at the same time the
9070 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009071
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009072- sets and frozensets now have an isdisjoint() method.
9073
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009074- optimize the performance of builtin.sum().
9075
Neal Norwitz44f326e2007-10-05 05:29:17 +00009076- Fix warnings found by the new version of the Coverity checker.
9077
Georg Brandl21e99f42010-03-07 15:23:59 +00009078- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009079 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9080 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009081
Georg Brandl3ee81df2008-05-17 18:14:43 +00009082- Issue #1686386: Tuple's tp_repr did not take into account the
9083 possibility of having a self-referential tuple, which is possible
9084 from C code. Nor did object's tp_str consider that a type's tp_str
9085 could do something that could lead to an inifinite recursion.
9086 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9087 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009088
Georg Brandl3ee81df2008-05-17 18:14:43 +00009089- Issue #1164: It was possible to trigger deadlock when using the
9090 'print' statement to write to a file since the GIL was not released
9091 as needed. Now PyObject_Print() does the right thing along with
9092 various tp_print implementations of the built-in types and those in
9093 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009094
Georg Brandl3ee81df2008-05-17 18:14:43 +00009095- Issue #1147: Exceptions were directly allowing string exceptions in
9096 their throw() method even though string exceptions no longer
9097 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009098

Brett Cannon1e534b52007-09-07 04:18:30 +00009102- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009103 PyObject_Call() never calling back out to Python code to trigger
9104 recursion depth updates/checks. Required the creation of a static
9105 RuntimeError instance in case normalizing an exception put the
9106 recursion check value past its limit. Fixes crashers
9107 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009108

Neal Norwitz0ac60192007-05-27 04:08:54 +00009122- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009123 __*__ attributes. (Some already existed, e.g., __doc__ and
9124 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009125
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009126- Add -3 option to the interpreter to warn about features that are
9127 deprecated and will be changed/removed in Python 3.0.
9128

9130 calls.
9131
Collin Winter62903052007-05-18 23:11:24 +00009132- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009133 "except E as target:". This is to provide forwards compatibility
9134 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009135
Brett Cannon229cee22007-05-05 01:34:02 +00009136- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009138- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009139 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009141- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009142 setting a plain string, ie don't expand to single letter identifiers.
9143
Raymond Hettinger13936692007-04-11 18:40:58 +00009144- Request #1191699: Slices can now be pickled.
9145

9148 remaining characters.
9149
Georg Brandl5cb76c12007-03-21 09:00:39 +00009150- Patch #1682205: a TypeError while unpacking an iterable is no longer

9154
Guido van Rossum143b5642007-03-23 04:58:42 +00009155- Bug #1683368: The object.__init__() and object.__new__() methods are
9156 now stricter in rejecting excess arguments. The only time when
9157 either allows excess arguments is when it is not overridden and the
9158 other one is. For backwards compatibility, when both are
9159 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009160 warning later). Also, type.__init__() insists on the same signature
9161 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009162
Georg Brandl3ee81df2008-05-17 18:14:43 +00009163- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9164 object to complex using its __complex__() method before falling back
9165 to the __float__() method. Therefore, the functions in the cmath
9166 module now can operate on objects that define a __complex__()
9167 method.

9171 same slot names.

9184
Georg Brandl7b9c5552007-03-12 14:30:05 +00009185- Bug #1678647: write a newline after printing an exception in any
9186 case, even when converting the value to a string failed.
9187
Georg Brandl871f1bc2007-03-12 13:17:36 +00009188- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009189 its argument, if it exists. If not, it will work like before. This
9190 allows customizing the output of dir() in the presence of a
9191 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009192
Collin Winter276887b2007-03-12 16:11:39 +00009193- Patch #922167: Python no longer segfaults when faced with infinitely
9194 self-recursive reload() calls (as reported by bug #742342).
9195

9200 parthensized forms. This means complex(repr(x)) now works instead of
9201 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009202
Georg Brandlaa2321b2007-03-07 00:40:28 +00009203- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009204 makes the filenames the warning module prints much more sensible
9205 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009206
Georg Brandl49aafc92007-03-07 00:34:46 +00009207- Variant of patch #697613: don't exit the interpreter on a SystemExit
9208 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009209 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00009218- Patch #1674228: when assigning a slice (old-style), check for the
9219 sq_ass_slice instead of the sq_slice slot.
9220
Georg Brandl3ee81df2008-05-17 18:14:43 +00009221- When printing an unraisable error, don't print exceptions. before
9222 the name. This duplicates the behavior whening normally printing
9223 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009755 AttributeError instead of an IOError when the server's response
9756 didn't contain a valid HTTP status line.

9847 TestCase and TestSuite subclasses (not instances) are no longer
9848 accepted in TestSuite.addTest(). This should cause no

10119 the first chunk fed to the decoder started with a BOM, but was
10120 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010121
Georg Brandl3ee81df2008-05-17 18:14:43 +000010122- The implementation of UnicodeError objects has been simplified

10129 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010130
Georg Brandl3ee81df2008-05-17 18:14:43 +000010131- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010132 that the SMTP.starttls() caller no longer needs to call ehlo()
10133 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010134 does not claim to support starttls. Adds the
10135 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010178- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010179 works as expected. ``mmap.find`` also takes an optional ``end``

10216 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10217 silently miscode subclasses of those types. Now, it raises a
10218 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010219

Georg Brandl3ee81df2008-05-17 18:14:43 +000010234 time so that opening a database previously created with the DB_DUP
10235 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10236 opens. Specifically: dictionary assignment to a DB object will
10237 replace all values for a given key when the database allows
10238 duplicate values. DB users should use DB.put(k, v) when they want
10239 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010240

10246 characters with ASCII value less than 32. Also, it correctly quotes
10247 dots only if they occur on a single line, as opposed to the previous
10248 behavior of quoting dots if they are the second character of any
10249 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010250

10577-----
10578
Georg Brandl3ee81df2008-05-17 18:14:43 +000010579- Unified naming convention for free lists and their limits. All free
10580 lists in Object/ are named ``free_list``, the counter ``numfree``
10581 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10582 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010583
Georg Brandl3ee81df2008-05-17 18:14:43 +000010584- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10585 to ``PyTuple_SetItem``, it can be used to populate a brand new
10586 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010587
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010588- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010589
Georg Brandl3ee81df2008-05-17 18:14:43 +000010590- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10591 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10592 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010593
10594- Patch #1720595: add T_BOOL to the range of structmember types.
10595
10596- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10597 ``PyFloat_GetInfo()`` to the float API.
10598
Georg Brandl3ee81df2008-05-17 18:14:43 +000010599- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10600 of w# format code incorrectly truncated the length to an int, even
10601 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10602 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010603
Georg Brandl3ee81df2008-05-17 18:14:43 +000010604- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10605 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010606
Georg Brandl3ee81df2008-05-17 18:14:43 +000010607- PEP 3123: Provide forward compatibility with Python 3.0, while
10608 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10609 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010610
Georg Brandl3ee81df2008-05-17 18:14:43 +000010611- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10612 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010613
10614- Patch #1733960: Allow T_LONGLONG to accept ints.
10615
10616- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10617
Christian Heimes000a0742008-01-03 22:16:32 +000010618- Added a new API function ``PyImport_ImportModuleNoBlock``.
10619
Georg Brandl6caad7d2008-01-26 14:19:22 +000010620- Bug #1637022: Prefix AST symbols with _Py_.
10621
10622- Fix some leftovers from the conversion from int to Py_ssize_t
10623 (relevant to strings and sequences of more than 2**31 items).
10624
10625- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10626 outside of pystate.c and should not be necessary.
10627
Georg Brandl3ee81df2008-05-17 18:14:43 +000010628- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10629 absolute imports. In earlier versions they might have used relative
10630 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010631
Georg Brandl3ee81df2008-05-17 18:14:43 +000010632- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10633 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010634
Georg Brandl3ee81df2008-05-17 18:14:43 +000010635- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10636 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010641- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10642 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10643 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10644 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010645
Georg Brandl3ee81df2008-05-17 18:14:43 +000010646- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10647 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010658- Removed the macfs module. It had been deprecated since Python 2.5.
10659 This lead to the deprecation of macostools.touched() as it relied
10660 solely on macfs and was a no-op under OS X.
