1228
1229- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1230 and later systems as is currently done for Python 3.x installers.
1231 For 2.7.7 only, we will provide three installers:
1232 the legacy deprecated 10.3+ 32-bit-only format;
1233 the newer 10.5+ 32-bit-only format;
1234 and the unchanged 10.6+ 64-/32-bit format.
1235 Although binary installers will no longer be available from
1236 python.org as of 2.7.8, it will still be possible to build from
1237 source on 10.3.9 and 10.4 systems if necessary.
1238 See Mac/BuildScript/README.txt for more information.

Ned Deily8e60f6e2013-05-30 00:14:29 -07001553- Issue #18098: The deprecated OS X Build Applet.app fails to build on

1561 64-bit/32-bit installer for 10.6+. It is no longer necessary
1562 to install a third-party version of Tcl/Tk 8.5 to work around the
1563 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
1564 and later releases.

Ned Deilyf84b5312013-10-25 00:44:46 -07001566- Issue #19019: Change the OS X installer build script to use CFLAGS instead
1567 of OPT for special build options. By setting OPT, some compiler-specific
1568 options like -fwrapv were overridden and thus not used, which could result
1569 in broken interpreters when building with clang.

2620 32-bit-only installer Pythons on systems with Xcode 4 (currently
2621 OS X 10.8, 10.7, and optionally 10.6).
2622 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2623 * Since Xcode 4 removes ppc support, extension module builds now
2624 check for ppc compiler support and by default remove ppc and
2625 ppc64 archs when they are not available.
2626 * Extension module builds now revert to using system installed
2627 headers and libs (/usr and /System/Library) if the SDK used
2628 to build the interpreter is not installed or has moved.
2629 * Try to avoid building extension modules with deprecated
2630 and problematic Apple llvm-gcc compiler. If original compiler
2631 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002995- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2996 int.__pow__. These overflow checks were causing int.__pow__ to produce
2997 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002998 compiler optimizing the check away. Also fix similar overflow checks
2999 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
3000 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01003068- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003069 has left two versions of customize_compiler, the original in
3070 distutils.sysconfig and another copy in distutils.ccompiler, with some

3073 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01003075- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3076 Distutils-based packages with C extension modules may fail because
3077 Apple has removed gcc-4.2, the version used to build python.org
3078 64-bit/32-bit Pythons. If the user does not explicitly override
3079 the default C compiler by setting the CC environment variable,
3080 Distutils will now attempt to compile extension modules with clang
3081 if gcc-4.2 is required but not found. Also as a convenience, if
3082 the user does explicitly set CC, substitute its value as the default
3083 compiler in the Distutils LDSHARED configuration variable for OS X.
3084 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3085 SDK, neither of which are available in Xcode 4. This change does not
3086 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003336- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3337 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3338 interpreter process. This could cause failures in non-Distutils subprocesses
3339 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003340 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003341 deployment target only in the environment of each build subprocess. It is
3342 still possible to globally override the default by setting
3343 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3344 greater or equal to the default value, the value with which the interpreter
3345 was built.

3374 updating the check interval, so if the user decreases the check interval,
3375 the ticker doesn't have to wind down to zero from the old starting point
3376 before the new interval takes effect. And if the user increases the
3377 interval, it makes sure the new limit takes effect right away rather have an
3378 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00004375- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4376 This prevents user-created self-referencing ordered dictionaries from
4377 becoming permanently uncollectable GC garbage. The downside is that
4378 removing __del__ means that the internal doubly-linked list has to wait for
4379 GC collection rather than freeing memory immediately when the refcnt drops
4380 to zero.

4388 to fetch the original errno, or to filter timeout errors. Now the
4389 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004838- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4839 start byte and the continuation byte(s) are now considered invalid, instead
4840 of the number of bytes specified by the start byte.
4841 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4842 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4843 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4844 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004852- Issue #8748: Fix two issues with comparisons between complex and integer
4853 objects. (1) The comparison could incorrectly return True in some cases
4854 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4855 (2) The comparison raised an OverflowError for large integers, leading
4856 to unpredictable exceptions when combining integers and complex objects
4857 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004859- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00005239- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5240 with a non-empty format string. This is an effort to future-proof user
5241 code. If a derived class does not currently implement __format__ but later
5242 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005243 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005244 Python 3.3 and it will be an error in Python 3.4.

5834-----------------
5835
Georg Brandlba83f822010-03-14 09:50:54 +00005836- The ``__complex__()`` method is now looked up on the class of instances to
5837 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005839- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

5841
Mark Dickinson1b34d252010-01-01 17:27:30 +00005842- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005843 DeprecationWarning when passed a float argument where an integer was expected.
5844 These functions and methods now raise TypeError instead. The majority of the
5845 effects of this change are in the extension modules, but some core functions
5846 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5847 and many unicode/str methods.

5859
Georg Brandlba83f822010-03-14 09:50:54 +00005860- Issue #1811: Improve accuracy and cross-platform consistency for true division
5861 of integers: the result of a/b is now correctly rounded for ints a and b (at
5862 least on IEEE 754 platforms), and in particular does not depend on the
5863 internal representation of a long.

5871
Georg Brandlba83f822010-03-14 09:50:54 +00005872 These executables now work properly with the arch(1) command: ``arch -ppc
5873 python`` will start a universal binary version of python in PPC mode (unlike

6013 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00006014

Georg Brandlba83f822010-03-14 09:50:54 +00006029- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6030 decimal string that's guaranteed to round back to x under correct rounding
6031 (with round-half-to-even rounding mode). Previously it gave a string based on
6032 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6033 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6034 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006035
Georg Brandlba83f822010-03-14 09:50:54 +00006036- Issue #7117: On almost all platforms: float-to-string and string-to-float
6037 conversions within Python are now correctly rounded. Places these conversions
6038 occur include: str for floats and complex numbers; the float and complex
6039 constructors; old-style and new-style numeric formatting; serialization and
6040 deserialization of floats and complex numbers using marshal, pickle and json;
6041 parsing of float and imaginary literals in Python code; Decimal-to-float
6042 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006043
Georg Brandlba83f822010-03-14 09:50:54 +00006044 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6045 providing correctly-rounded strtod and dtoa C functions. This code is
6046 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6047 the C compiler. There may be a small number of platforms on which correct
6048 operation of this code cannot be guaranteed, so the code is not used: notably,
6049 this applies to platforms where the C double format is not IEEE 754 binary64,
6050 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6051 and Python's configure script is unable to determine how to change the FPU
6052 precision. On these platforms conversions use the platform strtod and dtoa,
6053 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00006055- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6056 uses the correctly-rounded string <-> float conversions described above (when
6057 available), and so produces correctly rounded results that will display nicely
6058 under the float repr. There are two related small changes: (1) round now
6059 accepts any class with an ``__index__()`` method for its second argument (but
6060 no longer accepts floats for the second argument), and (2) an excessively
6061 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6062 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006209- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6210 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6211 but with at least one decimal point and with a default precision
6212 of 12. Previously, the behavior the same but with a default precision of 6.
6213 This more closely matches ``str()``, and reduces surprises when adding
6214 alignment flags to the empty presentation type. This also affects the new
6215 complex.__format__ in the same way.

6405 instead of throwing a MemoryError.
6406
Georg Brandlba83f822010-03-14 09:50:54 +00006407- Issue #3689: The list reversed iterator now supports __length_hint__ instead

6412
Georg Brandlba83f822010-03-14 09:50:54 +00006413- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6414 file objects with closefd=False. The file descriptor is still kept open but
6415 the file object behaves like a closed file. The ``FileIO`` object also got a
6416 new readonly attribute ``closefd``.

6435
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006436- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00006439- On windows, ``os.chdir()`` given unicode was not working if
6440 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6441 this code path is really executed because I cannot move to such directory on
6442 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006444- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6445 element is temporarily replaced with an equivalent frozenset. But the
6446 eventual KeyError would always report the empty ``frozenset()`` as the missing
6447 key. Now it correctly refers to the initial element.

6465 returned them on 64bit platforms.
6466
Walter Dörwalded960ac2009-05-03 22:36:33 +00006467- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6468 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6469 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6470 of using the replace error handler in PyUnicode_DecodeUTF8().
6471
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006472- Issue #3739: The unicode-internal encoder now reports the number of characters
6473 consumed like any other encoder (instead of the number of bytes).
6474
Georg Brandlba83f822010-03-14 09:50:54 +00006475- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6476 allocator will be automatically disabled when running under Valgrind. This
6477 gives improved memory leak detection when running under Valgrind, while taking
6478 advantage of pymalloc at other times.

7669 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7670 neither __int__ nor __long__, TypeError used to be raised (with a

7868
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007869- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7870 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7871 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7872 ``printf`` function, whereas PyString_FromFormat has an independent
7873 implementation and uses "%zd" on all platforms for size_t values.
7874 This makes a difference on win64, where ``printf`` needs "%Id" to display
7875 64bit values.

7881 object; previously an int would be returned for small values. the __long__
7882 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007892 was correctly parsed but parsing of subsequent arguments failed.
7893
Vinay Sajip35e3b032008-09-01 14:33:59 +00007894- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007895 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7896 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7897 when given a tuple of classes as second argument, were looking up
7898 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7899 type object.

8044-----------------
8045
Guido van Rossumf8402962008-08-20 15:01:50 +00008046- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8047 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8048 extensions do not automatically benefit from the class attribute
8049 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8050 to their tp_flags field if they care. This is a backwards
8051 compatibility feature; in 3.0, all types will use the cache by
8052 default.
8053
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008054- Keyword arguments can now follow starred arguments. (``f(a, *args,
8055 keyword=23)`` is now valid syntax.)
8056
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008057- ctypes function pointers that are COM methods have a boolean True
8058 value again.

8069
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008070- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8071 (64bit Unix, for example), unichr() would truncate its argument and return
8072 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008076- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8077 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8078
Antoine Pitrou92f82162008-07-25 22:22:08 +00008079- Issue #1819: function calls with several named parameters are now on
8080 average 35% faster (as measured by pybench).
8081
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008082- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8083 the python debugger steps into a class statement: the free variables (local
8084 variables defined in an outer scope) would be deleted from the outer scope.
8085
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008086- Issue #2620: Overflow checking when allocating or reallocating memory
8087 was not always being done properly in some python types and extension
8088 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8089 all been updated to perform better checks and places in the code that
8090 would previously leak memory on the error path when such an allocation
8091 failed have been fixed.

8099 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8100
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008101- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8102 version reported by these tools does not necessarily follow the python
8103 version numbering scheme, so the module is less strict when parsing it.
8104
Nick Coghlanf70385a2008-08-18 12:42:46 +00008105- Issue #2235: Added Py3k warnings for types which will become unhashable
8106 under the stricter __hash__ inheritance rules in 3.0. Several types
8107 which did not meet the rules for hash invariants and were already
8108 unhashable in 3.0 have now been explicitly flagged as unhashable in
8109 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8110 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8111
Brett Cannon88f801d2008-08-18 00:46:22 +00008112- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8113 imported into the module but exposed as part of the module's API.

8135
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008136- Issue #2676: in the email package, content-type parsing was hanging on
8137 pathological input because of quadratic or exponential behaviour of a
8138 regular expression.
8139
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008140- Issue #3476: binary buffered reading through the new "io" library is now
8141 thread-safe.
8142
Brett Cannonbf3157b2008-08-14 05:00:03 +00008143- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8144 since mimetools itself is deprecated. Because modules are cached, all
8145 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8146
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008147- Issue #3134: shutil referenced undefined WindowsError symbol.

8150 menu entries were not deleted.
8151
Brett Cannon83e81842008-08-09 23:30:55 +00008152- Copied the implementation of reduce() to _functools.reduce() to have a

8154
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008155- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8156 a MemoryError rather than silently stop the iteration.
8157
Guido van Rossum59ce9012008-08-09 14:55:34 +00008158- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8159 to _sre.compile() will now be rejected. This should not affect anybody
8160 since the re.compile() function never generates invalid re-bytecode.
8161
Skip Montanaroa032bf42008-08-08 22:52:51 +00008162- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8163 upon first access it can be automatically initialized from the csv file if
8164 it wasn't initialized during instantiation.
8165
Brett Cannon3aa2a492008-08-06 22:28:09 +00008166- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8167 the reload() built-in has been removed.
8168
Brett Cannon7e30b672008-08-04 21:52:25 +00008169- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008170 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

8178 raised an AttributeError.
8179
Benjamin Peterson01a24322008-07-28 23:35:27 +00008180- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00008181 asking for a specific length. This problem only affected files opened
8182 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008183

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008207- Issue #3394: zipfile.writestr sets external attributes when passed a
8208 file name rather than a ZipInfo instance, so files are extracted with
8209 mode 0600 rather than 000 under Unix.
8210
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008211- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8212 argument in python 2.5, this broke code that subclassed Popen to include its
8213 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00008223- Issue #2235: the C API function PyObject_HashNotImplemented and its
8224 interaction with the tp_hash slot (added in 2.6b2) are now documented
8225
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008226- Issue #643841: The language reference now provides more detailed
8227 coverage of the lookup process for special methods. The disclaimers
8228 regarding lack of coverage of new-style classes have also been
8229 removed, since the coverage is now fairly reasonable.

8233================================
8234
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008235*Release date: 17-Jul-2008*
8236
Raymond Hettingere3ae6552008-06-20 04:18:15 +00008237Core and Builtins
8238-----------------
8239
Georg Brandl3e483f62008-07-16 22:57:41 +00008240- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8241 its methods now allow for items objects that can be converted to
8242 an integer using operator.index().
8243
Mark Dickinson64b7e502008-07-16 09:40:03 +00008244- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8245 produced a ValueError instead of giving the correct float.
8246
Eric Smitha5fa5a22008-07-16 00:11:49 +00008247- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8248 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8249
Mark Dickinson7103aa42008-07-15 19:08:33 +00008250- Issue #3008: the float type has a new instance method 'float.hex'
8251 and a new class method 'float.fromhex' to convert floating-point
8252 numbers to and from hexadecimal strings, respectively.
8253
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008254- Issue #2235: __hash__ is once again inherited by default. To allow
8255 collections.Hashable to remain meaningful in the presence of the
8256 default hash implementation (object.__hash__), it is now possible
8257 to explicit block inheritance of hash by setting __hash__=None at
8258 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8259 level.
8260
Nick Coghlanb028f502008-07-13 14:52:36 +00008261- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8262 the parent module cannot be found while performing an absolute import.
8263 This means that an incorrectly defined __package__ attribute will
8264 now only prevent relative imports in that module rather than causing
8265 all imports from that module to fail.
8266
Nick Coghlan14ff9942008-07-08 14:21:42 +00008267- Issue #2517: Allow unicode messages in Exceptions again by correctly
8268 bypassing the instance dictionary when looking up __unicode__ on
8269 new-style classes.
8270
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008271- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8272 set to a custom object whose write() method happens to install
8273 another file in sys.stdout.
8274
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008275- Issue #3088: Corrected a race condition in classes derived from
8276 threading.local: the first member set by a thread could be saved in
8277 another thread's dictionary.
8278
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008279- Issue #3004: Minor change to slice.indices(): the start and stop
8280 arguments are now treated identically, making the behaviour easier
8281 to describe and understand. For example, slice(None, -10,
8282 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8283 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8284 10, -1).
8285
Georg Brandl278fc502008-07-19 12:46:12 +00008286- Issue #3219: Calling a function with repeated keyword arguments,
8287 f(a=2, a=23), would not cause a syntax error. This was a regression
8288 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008289
Georg Brandl278fc502008-07-19 12:46:12 +00008290- Issue #2862: Make int and float freelist management consistent with
8291 other freelists. Changes their CompactFreeList apis into
8292 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008293

8296
Thomas Heller57adf222008-08-14 19:10:48 +00008297- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8298 api functions without holding the GIL, which could lead to a fatal
8299 error when they failed.
8300
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008301- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00008309- Issue #3125: Remove copy_reg in multiprocessing and replace it with
8310 ForkingPickler.register() to resolve conflict with ctypes.
8311
Vinay Sajip51e65192008-07-18 09:01:10 +00008312- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00008314- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8315 a valid dlerror() message.
8316
Thomas Heller2bad6572008-07-15 17:19:50 +00008317- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8318 incomplete structure was created.
8319

8323
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008324- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008325
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008326- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8327 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008328 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008329 content-length. The problem had been corrected in the 2.4 branch, but never
8330 merged into trunk.
8331
Georg Brandle78fbcc2008-07-05 10:13:36 +00008332- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008343 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00008344
Nick Coghlanc060b0e2008-07-02 13:09:19 +00008345- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8346 handling is now the same as that of other special attributes like __name__).
8347
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008348- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
8349 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008736 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008737
8738 This is controlled by the configure argument ``--with-universal-archs``:
8739
8740 - ``--with-universal-archs=all``: install 4-way universal
8741
8742 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8743
8744 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8745
8746 This option should be used in combination with ``--enable-universalsdk=``.
8747
8748 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 +00008797- Issue #1631171: Re-implement the 'warnings' module in C (the
8798 original Python code has been kept as backup). This will allow for
8799 using the 'warning's machinery in such places as the parser where
8800 use of pure Python code is not possible. Both the ``showarning()``
8801 and ``formatwarning()`` gain an optional 'line' argument which is
8802 not called by default for backwards-compatibility reasons. Setting
8803 ``warnings.showwarning()`` to an implementation that lacks support
8804 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008867- Issue #2550: The approach used by client/server code for obtaining
8868 ports to listen on in network-oriented tests has been refined in an
8869 effort to facilitate running multiple instances of the entire
8870 regression test suite in parallel without issue.
8871 test_support.bind_port() has been fixed such that it will always
8872 return a unique port -- which wasn't always the case with the
8873 previous implementation, especially if socket options had been set
8874 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8875 new implementation of bind_port() will actually raise an exception
8876 if it is passed an AF_INET/SOCK_STREAM socket with either the
8877 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8878 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8879 the socket it's been passed. This currently only applies to
8880 Windows. This option prevents any other sockets from binding to the
8881 host/port we've bound to, thus removing the possibility of the
8882 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8883 when a second SOCK_STREAM socket binds and accepts to a host/port
8884 that's already been bound by another socket. The optional preferred
8885 port parameter to bind_port() has been removed. Under no
8886 circumstances should tests be hard coding ports!
8887
8888 test_support.find_unused_port() has also been introduced, which will
8889 pass a temporary socket object to bind_port() in order to obtain an
8890 unused port. The temporary socket object is then closed and
8891 deleted, and the port is returned. This method should only be used
8892 for obtaining an unused port in order to pass to an external program
8893 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8894 a parameter to a server-oriented class that doesn't give you direct
8895 access to the underlying socket used.
8896
8897 Finally, test_support.HOST has been introduced, which should be used
8898 for the host argument of any relevant socket calls (i.e. bind and
8899 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008900
8901 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008902 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

9173Core and builtins
9174-----------------
9175
Fred Drakea8ee94b2008-03-01 02:45:07 +00009176- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00009177 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00009178
Georg Brandlad61bc82008-02-23 15:11:18 +00009179- Issue #2067: file.__exit__() now calls subclasses' close() method.
9180
9181- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00009182
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009183- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00009184 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00009185
Eric Smitha73fbe72008-02-23 03:09:44 +00009186- Added the future_builtins module, which contains hex() and oct().
9187 These are the PEP 3127 version of these functions, designed to be
9188 compatible with the hex() and oct() builtins from Python 3.0. They
9189 differ slightly in their output formats from the existing, unchanged
9190 Python 2.6 builtins. The expected usage of the future_builtins
9191 module is:
9192 from future_builtins import hex, oct
9193
Eric Smith7ef40bf2008-02-20 23:34:22 +00009194- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9195 exponents for exponents with absolute value < 100. Follows C99
9196 standard. This is a change on Windows, which would use 3 digits.
9197 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9198 so that any alterations it does to the resulting string will be
9199 available in stringlib/formatter.h (for float.__format__).
9200
Eric Smith5a3c1352008-02-19 13:21:56 +00009201- Implemented PEP 3101, Advanced String Formatting. This adds a new
9202 builtin format(); a format() method for str and unicode; a
9203 __format__() method to object, str, unicode, int, long, float, and
9204 datetime; the class string.Formatter; and the C API
9205 PyObject_Format().
9206
Georg Brandl3ee81df2008-05-17 18:14:43 +00009207- Fixed several potential crashes, all caused by specially crafted
9208 __del__ methods exploiting objects in temporarily inconsistent
9209 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009210
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009211- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009212 prevent a possible crash: an Abstract Base Class would try to access
9213 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009214
Georg Brandl3ee81df2008-05-17 18:14:43 +00009215- Fixed repr() and str() of complex numbers with infinity or nan as
9216 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00009217
Georg Brandl3ee81df2008-05-17 18:14:43 +00009218- Clear all free lists during a gc.collect() of the highest generation
9219 in order to allow pymalloc to free more arenas. Python may give back
9220 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009221
Georg Brandl3ee81df2008-05-17 18:14:43 +00009222- Issue #2045: Fix an infinite recursion triggered when printing a
9223 subclass of collections.defaultdict, if its default_factory is set
9224 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009225
Christian Heimesf75dbef2008-02-08 00:11:31 +00009226- Fixed a minor memory leak in dictobject.c. The content of the free
9227 list was not freed on interpreter shutdown.
9228
Georg Brandl21e99f42010-03-07 15:23:59 +00009229- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009230 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009231
Georg Brandl3ee81df2008-05-17 18:14:43 +00009232- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9233 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009234 to compact the internal free lists of pre-allocted ints and floats.
9235
Georg Brandl3ee81df2008-05-17 18:14:43 +00009236- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9237 calls. Python expected the return type int but the fork familie
9238 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009239
Georg Brandl3ee81df2008-05-17 18:14:43 +00009240- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9241 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009242
Georg Brandl3ee81df2008-05-17 18:14:43 +00009243- Issue #2025: Add tuple.count() and tuple.index() methods to comply
9244 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00009245
Georg Brandl3ee81df2008-05-17 18:14:43 +00009246- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
9247 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00009248
Georg Brandl3ee81df2008-05-17 18:14:43 +00009249- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
9250 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009251
Georg Brandl3ee81df2008-05-17 18:14:43 +00009252- Patch #1473257: generator objects gain a gi_code attribute. This is
9253 the same object as the func_code attribute of the function that
9254 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009255
Georg Brandl3ee81df2008-05-17 18:14:43 +00009256- Issue #1920: "while 0" statements were completely removed by the
9257 compiler, even in the presence of an "else" clause, which is
9258 supposed to be run when the condition is false. Now the compiler
9259 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009260
Guido van Rossumeead05f2008-01-24 18:21:02 +00009261- A few crashers fixed: weakref_in_del.py (issue #1377858);
9262 loosing_dict_ref.py (issue #1303614, test67.py);
9263 borrowed_ref_[34].py (not in tracker).
9264
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009265- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009266 suppressed while an extension is loaded by calling SetErrorMode in
9267 dynload_win.c. The error is still reported properly.
9268
Georg Brandl3ee81df2008-05-17 18:14:43 +00009269- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009270 several extension methods and modules do not work without unicode
9271 support.
9272
Georg Brandl26543b12008-01-21 18:36:51 +00009273- Issue #1882: when compiling code from a string, encoding cookies in the
9274 second line of code were not always recognized correctly.
9275
Georg Brandl14404b62008-01-19 19:27:05 +00009276- Issue #1679: "0x" was taken as a valid integer literal.
9277
Georg Brandl6caad7d2008-01-26 14:19:22 +00009278- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009279 added.
9280
Christian Heimesc94e2b52008-01-14 04:13:37 +00009281- sys.float_info / PyFloat_GetInfo: The floating point information
9282 object was converted from a dict to a specialized structseq object.
9283
Georg Brandl3ee81df2008-05-17 18:14:43 +00009284- Patch #1816: Added sys.flags structseq. It exposes the status of
9285 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009286
Georg Brandl3ee81df2008-05-17 18:14:43 +00009287- Objects/structseq.c: Implemented new structseq representation. The
9288 patch makes structseqs (e.g. the return value of os.stat) more
9289 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009290
Georg Brandl3ee81df2008-05-17 18:14:43 +00009291- Patch #1700288: added a type attribute cache that caches method
9292 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009293
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009294- Bug #1776: __import__() no longer accepts filenames on any platform.
9295 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009296
Georg Brandlaed6c662008-01-07 17:25:53 +00009297- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9298
Georg Brandl3ee81df2008-05-17 18:14:43 +00009299- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9300 envvar and sys.dont_write_bytecode attribute. All these can be set
9301 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009302
Georg Brandl3ee81df2008-05-17 18:14:43 +00009303- Improve some exception messages when Windows fails to load an
9304 extension module. Now we get for example '%1 is not a valid Win32
9305 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009306
Georg Brandl3ee81df2008-05-17 18:14:43 +00009307- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009309- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9310 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009311
Christian Heimes0a8143f2007-12-18 23:22:54 +00009312- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009313 and INF. float("nan"), float("inf") and float("-inf") now work on
9314 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009315
Georg Brandl3ee81df2008-05-17 18:14:43 +00009316- Compiler now generates simpler and faster code for dictionary
9317 literals. The oparg for BUILD_MAP now indicates an estimated
9318 dictionary size. There is a new opcode, STORE_MAP, for adding
9319 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009320
Georg Brandl3ee81df2008-05-17 18:14:43 +00009321- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009323- Issue #1620: New property decorator syntax was modifying the
9324 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00009325
Georg Brandl3ee81df2008-05-17 18:14:43 +00009326- Issue #1538: Avoid copying string in split/rsplit if the split char
9327 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009328
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009329- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009330 SystemError.
9331
Nick Coghlanef01d822007-12-03 12:55:17 +00009332- PEP 366: Allow explicit relative imports when executing modules
9333 inside packages with the -m switch via a new module level
9334 __package__ attribute.
9335
Georg Brandl3ee81df2008-05-17 18:14:43 +00009336- Issue #1402: Fix a crash on exit, when another thread is still
9337 running, and if the deallocation of its frames somehow calls the
9338 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009339

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00009343 attribute of an empty cell object.
9344
Georg Brandl3ee81df2008-05-17 18:14:43 +00009345- Issue #1460: The utf-7 incremental decoder did not accept truncated
9346 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009347
Georg Brandl3ee81df2008-05-17 18:14:43 +00009348- Patch #1739468: Directories and zipfiles containing a __main__.py
9349 file can now be directly executed by passing their name to the
9350 interpreter. The directory/zipfile is automatically inserted as the
9351 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009352
Georg Brandl3ee81df2008-05-17 18:14:43 +00009353- Issue #1265: Fix a problem with sys.settrace, if the tracing
9354 function uses a generator expression when at the same time the
9355 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009356
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009357- sets and frozensets now have an isdisjoint() method.
9358
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009359- optimize the performance of builtin.sum().
9360
Neal Norwitz44f326e2007-10-05 05:29:17 +00009361- Fix warnings found by the new version of the Coverity checker.
9362
Georg Brandl21e99f42010-03-07 15:23:59 +00009363- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009364 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9365 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009366
Georg Brandl3ee81df2008-05-17 18:14:43 +00009367- Issue #1686386: Tuple's tp_repr did not take into account the
9368 possibility of having a self-referential tuple, which is possible
9369 from C code. Nor did object's tp_str consider that a type's tp_str
9370 could do something that could lead to an inifinite recursion.
9371 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9372 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009373
Georg Brandl3ee81df2008-05-17 18:14:43 +00009374- Issue #1164: It was possible to trigger deadlock when using the
9375 'print' statement to write to a file since the GIL was not released
9376 as needed. Now PyObject_Print() does the right thing along with
9377 various tp_print implementations of the built-in types and those in
9378 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009379
Georg Brandl3ee81df2008-05-17 18:14:43 +00009380- Issue #1147: Exceptions were directly allowing string exceptions in
9381 their throw() method even though string exceptions no longer
9382 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009383
Georg Brandl3ee81df2008-05-17 18:14:43 +00009384- Issue #1096: Prevent a segfault from getting the repr of a very
9385 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00009387- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009388 PyObject_Call() never calling back out to Python code to trigger
9389 recursion depth updates/checks. Required the creation of a static
9390 RuntimeError instance in case normalizing an exception put the
9391 recursion check value past its limit. Fixes crashers
9392 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009393
Georg Brandl3ee81df2008-05-17 18:14:43 +00009394- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009407- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009408 __*__ attributes. (Some already existed, e.g., __doc__ and
9409 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009410
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009411- Add -3 option to the interpreter to warn about features that are
9412 deprecated and will be changed/removed in Python 3.0.
9413

9415 calls.
9416
Collin Winter62903052007-05-18 23:11:24 +00009417- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009418 "except E as target:". This is to provide forwards compatibility
9419 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009420
Brett Cannon229cee22007-05-05 01:34:02 +00009421- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009423- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009424 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009426- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009427 setting a plain string, ie don't expand to single letter identifiers.
9428
Raymond Hettinger13936692007-04-11 18:40:58 +00009429- Request #1191699: Slices can now be pickled.

9439
Guido van Rossum143b5642007-03-23 04:58:42 +00009440- Bug #1683368: The object.__init__() and object.__new__() methods are
9441 now stricter in rejecting excess arguments. The only time when
9442 either allows excess arguments is when it is not overridden and the
9443 other one is. For backwards compatibility, when both are
9444 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009445 warning later). Also, type.__init__() insists on the same signature
9446 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009447
Georg Brandl3ee81df2008-05-17 18:14:43 +00009448- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9449 object to complex using its __complex__() method before falling back
9450 to the __float__() method. Therefore, the functions in the cmath
9451 module now can operate on objects that define a __complex__()
9452 method.

9469
Georg Brandl7b9c5552007-03-12 14:30:05 +00009470- Bug #1678647: write a newline after printing an exception in any
9471 case, even when converting the value to a string failed.
9472
Georg Brandl871f1bc2007-03-12 13:17:36 +00009473- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009474 its argument, if it exists. If not, it will work like before. This
9475 allows customizing the output of dir() in the presence of a
9476 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009477
Collin Winter276887b2007-03-12 16:11:39 +00009478- Patch #922167: Python no longer segfaults when faced with infinitely
9479 self-recursive reload() calls (as reported by bug #742342).
9480

9485 parthensized forms. This means complex(repr(x)) now works instead of
9486 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009487
Georg Brandlaa2321b2007-03-07 00:40:28 +00009488- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009489 makes the filenames the warning module prints much more sensible
9490 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009491
Georg Brandl49aafc92007-03-07 00:34:46 +00009492- Variant of patch #697613: don't exit the interpreter on a SystemExit
9493 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009494 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00009503- Patch #1674228: when assigning a slice (old-style), check for the
9504 sq_ass_slice instead of the sq_slice slot.
9505
Georg Brandl3ee81df2008-05-17 18:14:43 +00009506- When printing an unraisable error, don't print exceptions. before
9507 the name. This duplicates the behavior whening normally printing
9508 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010131- unittest now verifies more of its assumptions. In particular,
10132 TestCase and TestSuite subclasses (not instances) are no longer
10133 accepted in TestSuite.addTest(). This should cause no
10134 incompatibility since it never made sense with ordinary subclasses
10135 -- the failure just occurred later, with a more cumbersome
10136 exception.

10404 the first chunk fed to the decoder started with a BOM, but was
10405 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010406
Georg Brandl3ee81df2008-05-17 18:14:43 +000010407- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010416- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010417 that the SMTP.starttls() caller no longer needs to call ehlo()
10418 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010419 does not claim to support starttls. Adds the
10420 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010463- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010464 works as expected. ``mmap.find`` also takes an optional ``end``

10501 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10502 silently miscode subclasses of those types. Now, it raises a
10503 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010504

Georg Brandl3ee81df2008-05-17 18:14:43 +000010519 time so that opening a database previously created with the DB_DUP
10520 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10521 opens. Specifically: dictionary assignment to a DB object will
10522 replace all values for a given key when the database allows
10523 duplicate values. DB users should use DB.put(k, v) when they want
10524 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010525

10531 characters with ASCII value less than 32. Also, it correctly quotes
10532 dots only if they occur on a single line, as opposed to the previous
10533 behavior of quoting dots if they are the second character of any
10534 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010535

10862-----
10863
Georg Brandl3ee81df2008-05-17 18:14:43 +000010864- Unified naming convention for free lists and their limits. All free
10865 lists in Object/ are named ``free_list``, the counter ``numfree``
10866 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10867 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010868
Georg Brandl3ee81df2008-05-17 18:14:43 +000010869- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10870 to ``PyTuple_SetItem``, it can be used to populate a brand new
10871 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010872
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010873- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010875- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10876 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10877 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010878
10879- Patch #1720595: add T_BOOL to the range of structmember types.
10880
10881- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10882 ``PyFloat_GetInfo()`` to the float API.
10883
Georg Brandl3ee81df2008-05-17 18:14:43 +000010884- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10885 of w# format code incorrectly truncated the length to an int, even
10886 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10887 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010888
Georg Brandl3ee81df2008-05-17 18:14:43 +000010889- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10890 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010891
Georg Brandl3ee81df2008-05-17 18:14:43 +000010892- PEP 3123: Provide forward compatibility with Python 3.0, while
10893 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10894 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010895
Georg Brandl3ee81df2008-05-17 18:14:43 +000010896- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10897 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010898
10899- Patch #1733960: Allow T_LONGLONG to accept ints.
10900
10901- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

10906
10907- Fix some leftovers from the conversion from int to Py_ssize_t
10908 (relevant to strings and sequences of more than 2**31 items).
10909
10910- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10911 outside of pystate.c and should not be necessary.
10912
Georg Brandl3ee81df2008-05-17 18:14:43 +000010913- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10914 absolute imports. In earlier versions they might have used relative
10915 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010916
Georg Brandl3ee81df2008-05-17 18:14:43 +000010917- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10918 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010919
Georg Brandl3ee81df2008-05-17 18:14:43 +000010920- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10921 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010926- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10927 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10928 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10929 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010930
Georg Brandl3ee81df2008-05-17 18:14:43 +000010931- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10932 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +000010941- buildtools now raises a DeprecationWarning.
10942
Georg Brandl3ee81df2008-05-17 18:14:43 +000010943- Removed the macfs module. It had been deprecated since Python 2.5.
10944 This lead to the deprecation of macostools.touched() as it relied
10945 solely on macfs and was a no-op under OS X.
