1695 32-bit-only installer Pythons on systems with Xcode 4 (currently
1696 OS X 10.8, 10.7, and optionally 10.6).
1697 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1698 * Since Xcode 4 removes ppc support, extension module builds now
1699 check for ppc compiler support and by default remove ppc and
1700 ppc64 archs when they are not available.
1701 * Extension module builds now revert to using system installed
1702 headers and libs (/usr and /System/Library) if the SDK used
1703 to build the interpreter is not installed or has moved.
1704 * Try to avoid building extension modules with deprecated
1705 and problematic Apple llvm-gcc compiler. If original compiler
1706 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002057- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2058 int.__pow__. These overflow checks were causing int.__pow__ to produce
2059 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002060 compiler optimizing the check away. Also fix similar overflow checks
2061 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2062 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002130- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002131 has left two versions of customize_compiler, the original in
2132 distutils.sysconfig and another copy in distutils.ccompiler, with some

2135 is the case in 3.x.
2136
Ned Deily0d0ea482012-02-10 12:59:06 +01002137- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2138 Distutils-based packages with C extension modules may fail because
2139 Apple has removed gcc-4.2, the version used to build python.org
2140 64-bit/32-bit Pythons. If the user does not explicitly override
2141 the default C compiler by setting the CC environment variable,
2142 Distutils will now attempt to compile extension modules with clang
2143 if gcc-4.2 is required but not found. Also as a convenience, if
2144 the user does explicitly set CC, substitute its value as the default
2145 compiler in the Distutils LDSHARED configuration variable for OS X.
2146 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2147 SDK, neither of which are available in Xcode 4. This change does not
2148 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002398- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2399 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2400 interpreter process. This could cause failures in non-Distutils subprocesses
2401 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002402 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002403 deployment target only in the environment of each build subprocess. It is
2404 still possible to globally override the default by setting
2405 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2406 greater or equal to the default value, the value with which the interpreter
2407 was built.

2436 updating the check interval, so if the user decreases the check interval,
2437 the ticker doesn't have to wind down to zero from the old starting point
2438 before the new interval takes effect. And if the user increases the
2439 interval, it makes sure the new limit takes effect right away rather have an
2440 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003420- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3421 This prevents user-created self-referencing ordered dictionaries from
3422 becoming permanently uncollectable GC garbage. The downside is that
3423 removing __del__ means that the internal doubly-linked list has to wait for
3424 GC collection rather than freeing memory immediately when the refcnt drops
3425 to zero.

3433 to fetch the original errno, or to filter timeout errors. Now the
3434 original error is re-raised.

3882
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003883- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3884 start byte and the continuation byte(s) are now considered invalid, instead
3885 of the number of bytes specified by the start byte.
3886 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3887 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3888 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003897- Issue #8748: Fix two issues with comparisons between complex and integer
3898 objects. (1) The comparison could incorrectly return True in some cases
3899 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3900 (2) The comparison raised an OverflowError for large integers, leading
3901 to unpredictable exceptions when combining integers and complex objects
3902 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003904- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004284- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4285 with a non-empty format string. This is an effort to future-proof user
4286 code. If a derived class does not currently implement __format__ but later
4287 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004288 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004289 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00004782 file position when calling `truncate()`. It would previously change the file
4783 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004784 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4787 class used to represent files stored inside an archive. The new
4788 implementation is significantly faster and can be wrapped in a
4789 ``io.BufferedReader`` object for more speedups. It also solves an issue
4790 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004801- Issue #7748: Since unicode values are supported for some metadata options in
4802 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4803 encoded string for them. This ensures that the upload and register commands
4804 send the correct values to PyPI without any error.

4879-----------------
4880
Georg Brandlba83f822010-03-14 09:50:54 +00004881- The ``__complex__()`` method is now looked up on the class of instances to
4882 make it consistent with other special methods.

4886
Mark Dickinson1b34d252010-01-01 17:27:30 +00004887- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004888 DeprecationWarning when passed a float argument where an integer was expected.
4889 These functions and methods now raise TypeError instead. The majority of the
4890 effects of this change are in the extension modules, but some core functions
4891 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4892 and many unicode/str methods.

4906 of integers: the result of a/b is now correctly rounded for ints a and b (at
4907 least on IEEE 754 platforms), and in particular does not depend on the
4908 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004915 executables on OSX.
4916
Georg Brandlba83f822010-03-14 09:50:54 +00004917 These executables now work properly with the arch(1) command: ``arch -ppc
4918 python`` will start a universal binary version of python in PPC mode (unlike
4919 previous releases).

5058 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005059

Georg Brandlba83f822010-03-14 09:50:54 +00005074- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5075 decimal string that's guaranteed to round back to x under correct rounding
5076 (with round-half-to-even rounding mode). Previously it gave a string based on
5077 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5078 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5079 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005080
Georg Brandlba83f822010-03-14 09:50:54 +00005081- Issue #7117: On almost all platforms: float-to-string and string-to-float
5082 conversions within Python are now correctly rounded. Places these conversions
5083 occur include: str for floats and complex numbers; the float and complex
5084 constructors; old-style and new-style numeric formatting; serialization and
5085 deserialization of floats and complex numbers using marshal, pickle and json;
5086 parsing of float and imaginary literals in Python code; Decimal-to-float
5087 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005088
Georg Brandlba83f822010-03-14 09:50:54 +00005089 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5090 providing correctly-rounded strtod and dtoa C functions. This code is
5091 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5092 the C compiler. There may be a small number of platforms on which correct
5093 operation of this code cannot be guaranteed, so the code is not used: notably,
5094 this applies to platforms where the C double format is not IEEE 754 binary64,
5095 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5096 and Python's configure script is unable to determine how to change the FPU
5097 precision. On these platforms conversions use the platform strtod and dtoa,
5098 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005100- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5101 uses the correctly-rounded string <-> float conversions described above (when
5102 available), and so produces correctly rounded results that will display nicely
5103 under the float repr. There are two related small changes: (1) round now
5104 accepts any class with an ``__index__()`` method for its second argument (but
5105 no longer accepts floats for the second argument), and (2) an excessively
5106 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5107 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005254- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5255 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5256 but with at least one decimal point and with a default precision
5257 of 12. Previously, the behavior the same but with a default precision of 6.
5258 This more closely matches ``str()``, and reduces surprises when adding
5259 alignment flags to the empty presentation type. This also affects the new
5260 complex.__format__ in the same way.
5261

Georg Brandlba83f822010-03-14 09:50:54 +00005458- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5459 file objects with closefd=False. The file descriptor is still kept open but
5460 the file object behaves like a closed file. The ``FileIO`` object also got a

Walter Dörwalded960ac2009-05-03 22:36:33 +00005512- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5513 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5514 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5515 of using the replace error handler in PyUnicode_DecodeUTF8().
5516
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005517- Issue #3739: The unicode-internal encoder now reports the number of characters

5519
Georg Brandlba83f822010-03-14 09:50:54 +00005520- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5522 gives improved memory leak detection when running under Valgrind, while taking
5523 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006891- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6892
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006893- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6894 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6895 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6896 ``printf`` function, whereas PyString_FromFormat has an independent
6897 implementation and uses "%zd" on all platforms for size_t values.
6898 This makes a difference on win64, where ``printf`` needs "%Id" to display
6899 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006901- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6905 object; previously an int would be returned for small values. the __long__
6906 method is allowed to return either an int or a long, but the behaviour of
6907 float objects should not change to respect backward compatibility.
6908
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006909- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006915 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006916 was correctly parsed but parsing of subsequent arguments failed.
6917
Vinay Sajip35e3b032008-09-01 14:33:59 +00006918- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006919 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6920 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6921 when given a tuple of classes as second argument, were looking up
6922 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6923 type object.
6924

Brett Cannon1eaf0742008-09-02 01:25:16 +00006994 warnings.catch_warnings() along with some API cleanup. Expanding the tests

7068-----------------
7069
Guido van Rossumf8402962008-08-20 15:01:50 +00007070- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7071 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7072 extensions do not automatically benefit from the class attribute
7073 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7074 to their tp_flags field if they care. This is a backwards
7075 compatibility feature; in 3.0, all types will use the cache by
7076 default.
7077
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007078- Keyword arguments can now follow starred arguments. (``f(a, *args,
7079 keyword=23)`` is now valid syntax.)
7080
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007081- ctypes function pointers that are COM methods have a boolean True
7082 value again.
7083
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007084- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,

7086 and introducing s*.
7087
Georg Brandl1e13ea92008-08-11 09:07:59 +00007088- Issue #3537: Fix an assertion failure when an empty but presized dict
7089 object was stored in the freelist.
7090
Mark Dickinsonb6467572008-08-04 21:30:09 +00007091- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7092 ValueError consistently across platforms.
7093
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007094- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7095 (64bit Unix, for example), unichr() would truncate its argument and return
7096 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7097
Neal Norwitze7d8be82008-07-31 17:17:14 +00007098- Apply security patches from Apple.
7099
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007100- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

7102
Antoine Pitrou92f82162008-07-25 22:22:08 +00007103- Issue #1819: function calls with several named parameters are now on
7104 average 35% faster (as measured by pybench).
7105
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007106- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7107 the python debugger steps into a class statement: the free variables (local
7108 variables defined in an outer scope) would be deleted from the outer scope.
7109
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007110- Issue #2620: Overflow checking when allocating or reallocating memory
7111 was not always being done properly in some python types and extension
7112 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7113 all been updated to perform better checks and places in the code that
7114 would previously leak memory on the error path when such an allocation

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007120- Issue #3612: Added some missing basic types in ctypes.wintypes.
7121
Benjamin Petersone977ad42008-08-20 01:42:01 +00007122- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7123 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7124
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007125- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7126 version reported by these tools does not necessarily follow the python
7127 version numbering scheme, so the module is less strict when parsing it.
7128
Nick Coghlanf70385a2008-08-18 12:42:46 +00007129- Issue #2235: Added Py3k warnings for types which will become unhashable
7130 under the stricter __hash__ inheritance rules in 3.0. Several types
7131 which did not meet the rules for hash invariants and were already
7132 unhashable in 3.0 have now been explicitly flagged as unhashable in
7133 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7134 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7135
Brett Cannon88f801d2008-08-18 00:46:22 +00007136- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7137 imported into the module but exposed as part of the module's API.
7138
Brett Cannon7b96f072008-08-18 00:41:11 +00007139- Remove an unneeded import of abc.ABCMeta from 'inspect'.

7144
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007145- Issue #3575: Incremental decoder's decode function now takes bytearray
7146 by using 's*' instead of 't#'.
7147
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007148- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007149 fails unicode conversion on 2nd parameter. (windows only)
7150
Georg Brandl222e2082010-08-01 22:27:39 +00007151- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007152 in a redirect.
7153
Brett Cannonabe423e2008-08-16 21:47:07 +00007154- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007155 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007156
Facundo Batistaeb90b782008-08-16 14:44:07 +00007157- Issue #2776: fixed small issue when handling an URL with double slash
7158 after a 302 response in the case of not going through a proxy.
7159
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007160- Issue #2676: in the email package, content-type parsing was hanging on
7161 pathological input because of quadratic or exponential behaviour of a
7162 regular expression.
7163
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007164- Issue #3476: binary buffered reading through the new "io" library is now
7165 thread-safe.
7166
Brett Cannonbf3157b2008-08-14 05:00:03 +00007167- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7168 since mimetools itself is deprecated. Because modules are cached, all
7169 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7170
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007171- Issue #3134: shutil referenced undefined WindowsError symbol.
7172
Robert Schuppenies14646332008-08-10 11:01:53 +00007173- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7174 menu entries were not deleted.
7175
Brett Cannon83e81842008-08-09 23:30:55 +00007176- Copied the implementation of reduce() to _functools.reduce() to have a
7177 version that did not raise a DeprecationWarning under -3.
7178
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007179- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7180 a MemoryError rather than silently stop the iteration.
7181
Guido van Rossum59ce9012008-08-09 14:55:34 +00007182- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7183 to _sre.compile() will now be rejected. This should not affect anybody
7184 since the re.compile() function never generates invalid re-bytecode.
7185
Skip Montanaroa032bf42008-08-08 22:52:51 +00007186- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7187 upon first access it can be automatically initialized from the csv file if
7188 it wasn't initialized during instantiation.
7189
Brett Cannon3aa2a492008-08-06 22:28:09 +00007190- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7191 the reload() built-in has been removed.
7192
Brett Cannon7e30b672008-08-04 21:52:25 +00007193- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007194 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7202 raised an AttributeError.
7203
Benjamin Peterson01a24322008-07-28 23:35:27 +00007204- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007205 asking for a specific length. This problem only affected files opened
7206 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007207

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007231- Issue #3394: zipfile.writestr sets external attributes when passed a
7232 file name rather than a ZipInfo instance, so files are extracted with
7233 mode 0600 rather than 000 under Unix.
7234
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007235- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7236 argument in python 2.5, this broke code that subclassed Popen to include its
7237 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7248 interaction with the tp_hash slot (added in 2.6b2) are now documented
7249
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007250- Issue #643841: The language reference now provides more detailed
7251 coverage of the lookup process for special methods. The disclaimers
7252 regarding lack of coverage of new-style classes have also been
7253 removed, since the coverage is now fairly reasonable.

7257================================
7258
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007259*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007261Core and Builtins
7262-----------------
7263
Georg Brandl3e483f62008-07-16 22:57:41 +00007264- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7265 its methods now allow for items objects that can be converted to
7266 an integer using operator.index().
7267
Mark Dickinson64b7e502008-07-16 09:40:03 +00007268- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7269 produced a ValueError instead of giving the correct float.
7270
Eric Smitha5fa5a22008-07-16 00:11:49 +00007271- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7272 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7273
Mark Dickinson7103aa42008-07-15 19:08:33 +00007274- Issue #3008: the float type has a new instance method 'float.hex'
7275 and a new class method 'float.fromhex' to convert floating-point
7276 numbers to and from hexadecimal strings, respectively.
7277
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007278- Issue #2235: __hash__ is once again inherited by default. To allow
7279 collections.Hashable to remain meaningful in the presence of the
7280 default hash implementation (object.__hash__), it is now possible
7281 to explicit block inheritance of hash by setting __hash__=None at
7282 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7283 level.
7284
Nick Coghlanb028f502008-07-13 14:52:36 +00007285- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7286 the parent module cannot be found while performing an absolute import.
7287 This means that an incorrectly defined __package__ attribute will
7288 now only prevent relative imports in that module rather than causing
7289 all imports from that module to fail.
7290
Nick Coghlan14ff9942008-07-08 14:21:42 +00007291- Issue #2517: Allow unicode messages in Exceptions again by correctly
7292 bypassing the instance dictionary when looking up __unicode__ on
7293 new-style classes.
7294
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007295- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7296 set to a custom object whose write() method happens to install
7297 another file in sys.stdout.
7298
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007299- Issue #3088: Corrected a race condition in classes derived from
7300 threading.local: the first member set by a thread could be saved in
7301 another thread's dictionary.
7302
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007303- Issue #3004: Minor change to slice.indices(): the start and stop
7304 arguments are now treated identically, making the behaviour easier
7305 to describe and understand. For example, slice(None, -10,
7306 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7307 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7308 10, -1).
7309
Georg Brandl278fc502008-07-19 12:46:12 +00007310- Issue #3219: Calling a function with repeated keyword arguments,
7311 f(a=2, a=23), would not cause a syntax error. This was a regression
7312 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007313
Georg Brandl278fc502008-07-19 12:46:12 +00007314- Issue #2862: Make int and float freelist management consistent with
7315 other freelists. Changes their CompactFreeList apis into
7316 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007317

7319-------
7320
Thomas Heller57adf222008-08-14 19:10:48 +00007321- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7322 api functions without holding the GIL, which could lead to a fatal
7323 error when they failed.
7324
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007325- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007333- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7334 ForkingPickler.register() to resolve conflict with ctypes.
7335
Vinay Sajip51e65192008-07-18 09:01:10 +00007336- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007337
Thomas Heller880f5292008-07-15 19:39:38 +00007338- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7339 a valid dlerror() message.
7340
Thomas Heller2bad6572008-07-15 17:19:50 +00007341- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7342 incomplete structure was created.
7343

7347
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007348- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007349
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007350- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7351 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007352 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007353 content-length. The problem had been corrected in the 2.4 branch, but never
7354 merged into trunk.
7355
Georg Brandle78fbcc2008-07-05 10:13:36 +00007356- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00007368
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007369- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7370 handling is now the same as that of other special attributes like __name__).
7371
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007372- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7757
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007758- On MacOS X it is now possible to install the framework in 64-bit
7759 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007760 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007761
7762 This is controlled by the configure argument ``--with-universal-archs``:
7763
7764 - ``--with-universal-archs=all``: install 4-way universal
7765
7766 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7767
7768 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7769
7770 This option should be used in combination with ``--enable-universalsdk=``.
7771
7772 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 +00007821- Issue #1631171: Re-implement the 'warnings' module in C (the
7822 original Python code has been kept as backup). This will allow for
7823 using the 'warning's machinery in such places as the parser where
7824 use of pure Python code is not possible. Both the ``showarning()``
7825 and ``formatwarning()`` gain an optional 'line' argument which is
7826 not called by default for backwards-compatibility reasons. Setting
7827 ``warnings.showwarning()`` to an implementation that lacks support
7828 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007891- Issue #2550: The approach used by client/server code for obtaining
7892 ports to listen on in network-oriented tests has been refined in an
7893 effort to facilitate running multiple instances of the entire
7894 regression test suite in parallel without issue.
7895 test_support.bind_port() has been fixed such that it will always
7896 return a unique port -- which wasn't always the case with the
7897 previous implementation, especially if socket options had been set
7898 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7899 new implementation of bind_port() will actually raise an exception
7900 if it is passed an AF_INET/SOCK_STREAM socket with either the
7901 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7902 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7903 the socket it's been passed. This currently only applies to
7904 Windows. This option prevents any other sockets from binding to the
7905 host/port we've bound to, thus removing the possibility of the
7906 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7907 when a second SOCK_STREAM socket binds and accepts to a host/port
7908 that's already been bound by another socket. The optional preferred
7909 port parameter to bind_port() has been removed. Under no
7910 circumstances should tests be hard coding ports!
7911
7912 test_support.find_unused_port() has also been introduced, which will
7913 pass a temporary socket object to bind_port() in order to obtain an
7914 unused port. The temporary socket object is then closed and
7915 deleted, and the port is returned. This method should only be used
7916 for obtaining an unused port in order to pass to an external program
7917 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7918 a parameter to a server-oriented class that doesn't give you direct
7919 access to the underlying socket used.
7920
7921 Finally, test_support.HOST has been introduced, which should be used
7922 for the host argument of any relevant socket calls (i.e. bind and
7923 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007924
7925 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007926 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007927 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7928 test_asynchat and test_socket_ssl.
7929
Georg Brandl3ee81df2008-05-17 18:14:43 +00007930 It is now possible for multiple instances of the regression test
7931 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00008206
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008207- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008208 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008209
Eric Smitha73fbe72008-02-23 03:09:44 +00008210- Added the future_builtins module, which contains hex() and oct().
8211 These are the PEP 3127 version of these functions, designed to be
8212 compatible with the hex() and oct() builtins from Python 3.0. They
8213 differ slightly in their output formats from the existing, unchanged
8214 Python 2.6 builtins. The expected usage of the future_builtins
8215 module is:
8216 from future_builtins import hex, oct
8217
Eric Smith7ef40bf2008-02-20 23:34:22 +00008218- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8219 exponents for exponents with absolute value < 100. Follows C99
8220 standard. This is a change on Windows, which would use 3 digits.
8221 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8222 so that any alterations it does to the resulting string will be
8223 available in stringlib/formatter.h (for float.__format__).
8224
Eric Smith5a3c1352008-02-19 13:21:56 +00008225- Implemented PEP 3101, Advanced String Formatting. This adds a new
8226 builtin format(); a format() method for str and unicode; a
8227 __format__() method to object, str, unicode, int, long, float, and
8228 datetime; the class string.Formatter; and the C API
8229 PyObject_Format().
8230
Georg Brandl3ee81df2008-05-17 18:14:43 +00008231- Fixed several potential crashes, all caused by specially crafted
8232 __del__ methods exploiting objects in temporarily inconsistent
8233 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008234
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008235- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008236 prevent a possible crash: an Abstract Base Class would try to access
8237 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008238
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239- Fixed repr() and str() of complex numbers with infinity or nan as
8240 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008241
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- Clear all free lists during a gc.collect() of the highest generation
8243 in order to allow pymalloc to free more arenas. Python may give back
8244 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008245
Georg Brandl3ee81df2008-05-17 18:14:43 +00008246- Issue #2045: Fix an infinite recursion triggered when printing a
8247 subclass of collections.defaultdict, if its default_factory is set
8248 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008249
Christian Heimesf75dbef2008-02-08 00:11:31 +00008250- Fixed a minor memory leak in dictobject.c. The content of the free
8251 list was not freed on interpreter shutdown.
8252
Georg Brandl21e99f42010-03-07 15:23:59 +00008253- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008254 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008255
Georg Brandl3ee81df2008-05-17 18:14:43 +00008256- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8257 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008258 to compact the internal free lists of pre-allocted ints and floats.
8259
Georg Brandl3ee81df2008-05-17 18:14:43 +00008260- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8261 calls. Python expected the return type int but the fork familie
8262 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008263
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8265 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008266
Georg Brandl3ee81df2008-05-17 18:14:43 +00008267- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8268 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008269
Georg Brandl3ee81df2008-05-17 18:14:43 +00008270- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8271 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008272
Georg Brandl3ee81df2008-05-17 18:14:43 +00008273- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8274 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008275
Georg Brandl3ee81df2008-05-17 18:14:43 +00008276- Patch #1473257: generator objects gain a gi_code attribute. This is
8277 the same object as the func_code attribute of the function that
8278 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008279
Georg Brandl3ee81df2008-05-17 18:14:43 +00008280- Issue #1920: "while 0" statements were completely removed by the
8281 compiler, even in the presence of an "else" clause, which is
8282 supposed to be run when the condition is false. Now the compiler
8283 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008284
Guido van Rossumeead05f2008-01-24 18:21:02 +00008285- A few crashers fixed: weakref_in_del.py (issue #1377858);
8286 loosing_dict_ref.py (issue #1303614, test67.py);
8287 borrowed_ref_[34].py (not in tracker).
8288
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008289- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008290 suppressed while an extension is loaded by calling SetErrorMode in
8291 dynload_win.c. The error is still reported properly.
8292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008294 several extension methods and modules do not work without unicode
8295 support.
8296
Georg Brandl26543b12008-01-21 18:36:51 +00008297- Issue #1882: when compiling code from a string, encoding cookies in the
8298 second line of code were not always recognized correctly.
8299
Georg Brandl14404b62008-01-19 19:27:05 +00008300- Issue #1679: "0x" was taken as a valid integer literal.
8301
Georg Brandl6caad7d2008-01-26 14:19:22 +00008302- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008303 added.
8304
Christian Heimesc94e2b52008-01-14 04:13:37 +00008305- sys.float_info / PyFloat_GetInfo: The floating point information
8306 object was converted from a dict to a specialized structseq object.
8307
Georg Brandl3ee81df2008-05-17 18:14:43 +00008308- Patch #1816: Added sys.flags structseq. It exposes the status of
8309 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008310
Georg Brandl3ee81df2008-05-17 18:14:43 +00008311- Objects/structseq.c: Implemented new structseq representation. The
8312 patch makes structseqs (e.g. the return value of os.stat) more
8313 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008314
Georg Brandl3ee81df2008-05-17 18:14:43 +00008315- Patch #1700288: added a type attribute cache that caches method
8316 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008317
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008318- Bug #1776: __import__() no longer accepts filenames on any platform.
8319 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008320
Georg Brandlaed6c662008-01-07 17:25:53 +00008321- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8322
Georg Brandl3ee81df2008-05-17 18:14:43 +00008323- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8324 envvar and sys.dont_write_bytecode attribute. All these can be set
8325 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008326
Georg Brandl3ee81df2008-05-17 18:14:43 +00008327- Improve some exception messages when Windows fails to load an
8328 extension module. Now we get for example '%1 is not a valid Win32
8329 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008330
Georg Brandl3ee81df2008-05-17 18:14:43 +00008331- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008333- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8334 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008335
Christian Heimes0a8143f2007-12-18 23:22:54 +00008336- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008337 and INF. float("nan"), float("inf") and float("-inf") now work on
8338 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008339
Georg Brandl3ee81df2008-05-17 18:14:43 +00008340- Compiler now generates simpler and faster code for dictionary
8341 literals. The oparg for BUILD_MAP now indicates an estimated
8342 dictionary size. There is a new opcode, STORE_MAP, for adding
8343 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008344
Georg Brandl3ee81df2008-05-17 18:14:43 +00008345- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008350- Issue #1538: Avoid copying string in split/rsplit if the split char
8351 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008352
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008353- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008354 SystemError.
8355
Nick Coghlanef01d822007-12-03 12:55:17 +00008356- PEP 366: Allow explicit relative imports when executing modules

8358 __package__ attribute.
8359
Georg Brandl3ee81df2008-05-17 18:14:43 +00008360- Issue #1402: Fix a crash on exit, when another thread is still
8361 running, and if the deallocation of its frames somehow calls the
8362 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008363

8373 file can now be directly executed by passing their name to the
8374 interpreter. The directory/zipfile is automatically inserted as the
8375 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008376
Georg Brandl3ee81df2008-05-17 18:14:43 +00008377- Issue #1265: Fix a problem with sys.settrace, if the tracing
8378 function uses a generator expression when at the same time the
8379 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008380
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008381- sets and frozensets now have an isdisjoint() method.
8382
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008383- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00008385- Fix warnings found by the new version of the Coverity checker.
8386
Georg Brandl21e99f42010-03-07 15:23:59 +00008387- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008388 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8389 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008390
Georg Brandl3ee81df2008-05-17 18:14:43 +00008391- Issue #1686386: Tuple's tp_repr did not take into account the
8392 possibility of having a self-referential tuple, which is possible
8393 from C code. Nor did object's tp_str consider that a type's tp_str
8394 could do something that could lead to an inifinite recursion.
8395 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8396 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008397
Georg Brandl3ee81df2008-05-17 18:14:43 +00008398- Issue #1164: It was possible to trigger deadlock when using the
8399 'print' statement to write to a file since the GIL was not released
8400 as needed. Now PyObject_Print() does the right thing along with
8401 various tp_print implementations of the built-in types and those in
8402 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008403
Georg Brandl3ee81df2008-05-17 18:14:43 +00008404- Issue #1147: Exceptions were directly allowing string exceptions in
8405 their throw() method even though string exceptions no longer
8406 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008407

Brett Cannon1e534b52007-09-07 04:18:30 +00008411- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008412 PyObject_Call() never calling back out to Python code to trigger
8413 recursion depth updates/checks. Required the creation of a static
8414 RuntimeError instance in case normalizing an exception put the
8415 recursion check value past its limit. Fixes crashers
8416 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008417

Neal Norwitz0ac60192007-05-27 04:08:54 +00008431- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008432 __*__ attributes. (Some already existed, e.g., __doc__ and
8433 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008434
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008435- Add -3 option to the interpreter to warn about features that are
8436 deprecated and will be changed/removed in Python 3.0.
8437
Georg Brandl2134e752007-05-21 20:34:16 +00008438- Patch #1686487: you can now pass any mapping after '**' in function
8439 calls.
8440
Collin Winter62903052007-05-18 23:11:24 +00008441- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008442 "except E as target:". This is to provide forwards compatibility
8443 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008450- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008451 setting a plain string, ie don't expand to single letter identifiers.

Raymond Hettinger13936692007-04-11 18:40:58 +00008453- Request #1191699: Slices can now be pickled.
8454
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008455- Request #1193128: str.translate() now allows a None argument for
8456 translations that only remove characters without re-mapping the
8457 remaining characters.
8458
Georg Brandl5cb76c12007-03-21 09:00:39 +00008459- Patch #1682205: a TypeError while unpacking an iterable is no longer
8460 masked by a generic one with the message "unpack non-sequence".

8463
Guido van Rossum143b5642007-03-23 04:58:42 +00008464- Bug #1683368: The object.__init__() and object.__new__() methods are
8465 now stricter in rejecting excess arguments. The only time when
8466 either allows excess arguments is when it is not overridden and the
8467 other one is. For backwards compatibility, when both are
8468 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008469 warning later). Also, type.__init__() insists on the same signature
8470 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008472- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8473 object to complex using its __complex__() method before falling back
8474 to the __float__() method. Therefore, the functions in the cmath
8475 module now can operate on objects that define a __complex__()
8476 method.

8480 same slot names.

8487 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008494- Bug #1678647: write a newline after printing an exception in any
8495 case, even when converting the value to a string failed.
8496
Georg Brandl871f1bc2007-03-12 13:17:36 +00008497- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008498 its argument, if it exists. If not, it will work like before. This
8499 allows customizing the output of dir() in the presence of a
8500 __getattr__().

8509 parthensized forms. This means complex(repr(x)) now works instead of
8510 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008511
Georg Brandlaa2321b2007-03-07 00:40:28 +00008512- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008513 makes the filenames the warning module prints much more sensible
8514 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008515

Georg Brandl0fca97a2007-03-05 22:28:08 +00008527- Patch #1674228: when assigning a slice (old-style), check for the
8528 sq_ass_slice instead of the sq_slice slot.
8529
Georg Brandl3ee81df2008-05-17 18:14:43 +00008530- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008582- Bug #1545497: when given an explicit base, int() did ignore NULs
8583 embedded in the string to convert.
8584
Georg Brandl846f73a2006-10-08 07:11:54 +00008585- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00008633 generator expressions (x for x, in ... ) works again. Fixing this

Georg Brandl3ee81df2008-05-17 18:14:43 +00009064 AttributeError instead of an IOError when the server's response
9065 didn't contain a valid HTTP status line.

9156 TestCase and TestSuite subclasses (not instances) are no longer
9157 accepted in TestSuite.addTest(). This should cause no
9158 incompatibility since it never made sense with ordinary subclasses
9159 -- the failure just occurred later, with a more cumbersome
9160 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009431- The implementation of UnicodeError objects has been simplified
9432 (start and end attributes are now stored directly as Py_ssize_t
9433 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009434
Georg Brandl3ee81df2008-05-17 18:14:43 +00009435- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9436 with RFC 3207 and forgets any knowledge obtained from the server not
9437 obtained from the TLS negotiation itself. Patch contributed by Bill
9438 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009439
Georg Brandl3ee81df2008-05-17 18:14:43 +00009440- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009441 that the SMTP.starttls() caller no longer needs to call ehlo()
9442 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009443 does not claim to support starttls. Adds the
9444 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9445 Fenner.

9525 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9526 silently miscode subclasses of those types. Now, it raises a
9527 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009528

Georg Brandl3ee81df2008-05-17 18:14:43 +00009543 time so that opening a database previously created with the DB_DUP
9544 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9545 opens. Specifically: dictionary assignment to a DB object will
9546 replace all values for a given key when the database allows
9547 duplicate values. DB users should use DB.put(k, v) when they want
9548 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009549

9555 characters with ASCII value less than 32. Also, it correctly quotes
9556 dots only if they occur on a single line, as opposed to the previous
9557 behavior of quoting dots if they are the second character of any
9558 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009559

Georg Brandl3ee81df2008-05-17 18:14:43 +00009967- Removed the macfs module. It had been deprecated since Python 2.5.
9968 This lead to the deprecation of macostools.touched() as it relied
9969 solely on macfs and was a no-op under OS X.
