Mark Hammond323b5da2011-10-17 11:05:36 +110035- Issue #7833: Extension modules built using distutils on Windows will no
36 longer include a "manifest" to prevent them failing at import time in some
37 embedded situations.
38
Benjamin Petersona7b09762011-10-15 13:43:21 -040039- Issue #13186: Fix __delitem__ on old-style instances when invoked through

Mark Dickinsondbbed042011-09-19 16:38:08 +010048- Issue #12973: Fix overflow checks that invoked undefined behaviour in
49 int.__pow__. These overflow checks were causing int.__pow__ to produce
50 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010051 compiler optimizing the check away. Also fix similar overflow checks
52 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
53 bugs caused test failures with recent versions of Clang.

65 cleared by the garbage collector. This fixes a segfault when an instance
66 and its type get caught in a reference cycle, and the instance's
67 deallocator calls one of the methods on the type (e.g. when subclassing
68 IOBase). Diagnosis and patch by Davide Rizzo.
69
Victor Stinnerba8b3a22011-07-08 02:07:45 +020070- Issue #12501: Adjust callable() warning: callable() is only not supported in

72

78 raw_input() interrupted by CTRL+c.
79
Łukasz Langa7a153902011-10-18 17:16:00 +020080- Issue #10860: httplib now correctly handles an empty port after port
81 delimiter in URLs.

Ned Deily87e82bb2011-06-28 19:52:59 -0700317- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
318 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
319 interpreter process. This could cause failures in non-Distutils subprocesses
320 and was unreliable since tests or user programs could modify the interpreter
321 environment after Distutils set it. Instead, have Distutils set the the
322 deployment target only in the environment of each build subprocess. It is
323 still possible to globally override the default by setting
324 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
325 greater or equal to the default value, the value with which the interpreter
326 was built.

356 the ticker doesn't have to wind down to zero from the old starting point
357 before the new interval takes effect. And if the user increases the
358 interval, it makes sure the new limit takes effect right away rather have an
359 early task switch before recognizing the new interval.

1271 This prevents user-created self-referencing ordered dictionaries from
1272 becoming permanently uncollectable GC garbage. The downside is that
1273 removing __del__ means that the internal doubly-linked list has to wait for
1274 GC collection rather than freeing memory immediately when the refcnt drops
1275 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001734- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1735 start byte and the continuation byte(s) are now considered invalid, instead
1736 of the number of bytes specified by the start byte.
1737 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1738 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1749 objects. (1) The comparison could incorrectly return True in some cases
1750 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

2119
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002120- Issue #7301: Add environment variable $PYTHONWARNINGS.
2121
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002122- Issue #8329: Don't return the same lists from select.select when no fds are
2123 changed.
2124
Georg Brandlfee0f442010-05-22 21:26:21 +00002125- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002126 on 64-bit machines. The shift count for either left or right shift is
2127 permitted to be up to sys.maxsize.
2128
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002129- Ensure that tokenization of identifiers is not affected by locale.

2134
Georg Brandlfee0f442010-05-22 21:26:21 +00002135- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2136 with a non-empty format string. This is an effort to future-proof user
2137 code. If a derived class does not currently implement __format__ but later
2138 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002139 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002140 Python 3.3 and it will be an error in Python 3.4.

Victor Stinner66644262010-03-10 22:30:19 +00002155- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002156 (SIGINT). If an error occurs while importing the site module, the error is

Georg Brandlfee0f442010-05-22 21:26:21 +00002173- Issue #8257: The Decimal construct now accepts a float instance directly,
2174 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002175

Georg Brandlfee0f442010-05-22 21:26:21 +00002190- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2191 InvalidOperation instead of returning False. (Comparisons involving a quiet
2192 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2193 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002194
Georg Brandlfee0f442010-05-22 21:26:21 +00002195- Issue #2531: Comparison operations between floats and Decimal instances now
2196 return a result based on the numeric values of the operands; previously they
2197 returned an arbitrary result based on the relative ordering of id(float) and
2198 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002199
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002200- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002201 argument `-` which tells it to read files to compile from stdin. Each line is
2202 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00002212- Comparisons using one of <, <=, >, >= between a complex instance and a
2213 Fractions instance now raise TypeError instead of returning True/False. This
2214 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2215 <=> complex, and complex <=> complex comparisons.

2324 the set of integer codes for which it was used differed between native packing
2325 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002577- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2578 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2579 returning NULL. The macro now returns a statically allocated empty string
2580 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002626 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00002633 file position when calling `truncate()`. It would previously change the file
2634 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002635 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2636

2638 class used to represent files stored inside an archive. The new
2639 implementation is significantly faster and can be wrapped in a
2640 ``io.BufferedReader`` object for more speedups. It also solves an issue
2641 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002652- Issue #7748: Since unicode values are supported for some metadata options in
2653 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2654 encoded string for them. This ensures that the upload and register commands
2655 send the correct values to PyPI without any error.

2731
Georg Brandlba83f822010-03-14 09:50:54 +00002732- The ``__complex__()`` method is now looked up on the class of instances to
2733 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002735- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2736 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2737
Mark Dickinson1b34d252010-01-01 17:27:30 +00002738- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002739 DeprecationWarning when passed a float argument where an integer was expected.
2740 These functions and methods now raise TypeError instead. The majority of the
2741 effects of this change are in the extension modules, but some core functions
2742 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2743 and many unicode/str methods.

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00002752
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002753- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2754 used to drop the time part of the result.
2755
Georg Brandlba83f822010-03-14 09:50:54 +00002756- Issue #1811: Improve accuracy and cross-platform consistency for true division
2757 of integers: the result of a/b is now correctly rounded for ints a and b (at
2758 least on IEEE 754 platforms), and in particular does not depend on the
2759 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002760
Georg Brandlba83f822010-03-14 09:50:54 +00002761- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2762 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2763 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002764

Ronald Oussoren92919a62009-12-24 13:30:58 +00002766 executables on OSX.
2767
Georg Brandlba83f822010-03-14 09:50:54 +00002768 These executables now work properly with the arch(1) command: ``arch -ppc
2769 python`` will start a universal binary version of python in PPC mode (unlike
2770 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002771
Georg Brandlba83f822010-03-14 09:50:54 +00002772- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2773 underlying error when the coercion fails for the left hand operand.

Antoine Pitrou80157252010-01-08 19:20:17 +00002792- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002793 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2794 alternative to cPickle if you care about performance. Patch by Florent

2830 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2831 the same as passing no argument.
2832
Georg Brandlba83f822010-03-14 09:50:54 +00002833- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

2857 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

2910 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002911

Georg Brandlba83f822010-03-14 09:50:54 +00002926- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2927 decimal string that's guaranteed to round back to x under correct rounding
2928 (with round-half-to-even rounding mode). Previously it gave a string based on
2929 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2930 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2931 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002932
Georg Brandlba83f822010-03-14 09:50:54 +00002933- Issue #7117: On almost all platforms: float-to-string and string-to-float
2934 conversions within Python are now correctly rounded. Places these conversions
2935 occur include: str for floats and complex numbers; the float and complex
2936 constructors; old-style and new-style numeric formatting; serialization and
2937 deserialization of floats and complex numbers using marshal, pickle and json;
2938 parsing of float and imaginary literals in Python code; Decimal-to-float
2939 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002940
Georg Brandlba83f822010-03-14 09:50:54 +00002941 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2942 providing correctly-rounded strtod and dtoa C functions. This code is
2943 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2944 the C compiler. There may be a small number of platforms on which correct
2945 operation of this code cannot be guaranteed, so the code is not used: notably,
2946 this applies to platforms where the C double format is not IEEE 754 binary64,
2947 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2948 and Python's configure script is unable to determine how to change the FPU
2949 precision. On these platforms conversions use the platform strtod and dtoa,
2950 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002951
Georg Brandlba83f822010-03-14 09:50:54 +00002952- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2953 uses the correctly-rounded string <-> float conversions described above (when
2954 available), and so produces correctly rounded results that will display nicely
2955 under the float repr. There are two related small changes: (1) round now
2956 accepts any class with an ``__index__()`` method for its second argument (but
2957 no longer accepts floats for the second argument), and (2) an excessively
2958 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2959 raises an exception.

2962
Georg Brandlba83f822010-03-14 09:50:54 +00002963- Fix several issues with ``compile()``. The input can now contain Windows and
2964 Mac newlines and is no longer required to end in a newline.

3309
Georg Brandlba83f822010-03-14 09:50:54 +00003310- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

Georg Brandlba83f822010-03-14 09:50:54 +00003336- On windows, ``os.chdir()`` given unicode was not working if

3338 this code path is really executed because I cannot move to such directory on
3339 win2k)

3365 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004742- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4743 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4744 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4745 ``printf`` function, whereas PyString_FromFormat has an independent
4746 implementation and uses "%zd" on all platforms for size_t values.
4747 This makes a difference on win64, where ``printf`` needs "%Id" to display
4748 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00004768 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00004843 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4844 for catch_warnings() also led to an improvement in the raising of a
4845 DeprecationWarning related to warnings.warn_explicit().
4846

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004911What's New in Python 2.6 beta 3?
4912================================
4913
Barry Warsaw07a4a382008-08-21 01:15:08 +00004914*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004915
4916Core and Builtins
4917-----------------
4918
Guido van Rossumf8402962008-08-20 15:01:50 +00004919- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4920 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4921 extensions do not automatically benefit from the class attribute
4922 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4923 to their tp_flags field if they care. This is a backwards
4924 compatibility feature; in 3.0, all types will use the cache by
4925 default.
4926
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004927- Keyword arguments can now follow starred arguments. (``f(a, *args,
4928 keyword=23)`` is now valid syntax.)
4929
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004930- ctypes function pointers that are COM methods have a boolean True
4931 value again.
4932
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004933- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4934 by denying s# to parse objects that have a releasebuffer procedure,
4935 and introducing s*.
4936
Georg Brandl1e13ea92008-08-11 09:07:59 +00004937- Issue #3537: Fix an assertion failure when an empty but presized dict
4938 object was stored in the freelist.
4939
Mark Dickinsonb6467572008-08-04 21:30:09 +00004940- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4941 ValueError consistently across platforms.
4942
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004943- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4944 (64bit Unix, for example), unichr() would truncate its argument and return
4945 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4946
Neal Norwitze7d8be82008-07-31 17:17:14 +00004947- Apply security patches from Apple.
4948
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004949- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4950 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4951
Antoine Pitrou92f82162008-07-25 22:22:08 +00004952- Issue #1819: function calls with several named parameters are now on
4953 average 35% faster (as measured by pybench).
4954
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004955- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4956 the python debugger steps into a class statement: the free variables (local
4957 variables defined in an outer scope) would be deleted from the outer scope.
4958
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004959- Issue #2620: Overflow checking when allocating or reallocating memory
4960 was not always being done properly in some python types and extension
4961 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4962 all been updated to perform better checks and places in the code that
4963 would previously leak memory on the error path when such an allocation
4964 failed have been fixed.

4967-------
4968
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004969- Issue #3612: Added some missing basic types in ctypes.wintypes.
4970
Benjamin Petersone977ad42008-08-20 01:42:01 +00004971- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4972 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4973
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004974- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4975 version reported by these tools does not necessarily follow the python
4976 version numbering scheme, so the module is less strict when parsing it.
4977
Nick Coghlanf70385a2008-08-18 12:42:46 +00004978- Issue #2235: Added Py3k warnings for types which will become unhashable
4979 under the stricter __hash__ inheritance rules in 3.0. Several types
4980 which did not meet the rules for hash invariants and were already
4981 unhashable in 3.0 have now been explicitly flagged as unhashable in
4982 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4983 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4984
Brett Cannon88f801d2008-08-18 00:46:22 +00004985- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4986 imported into the module but exposed as part of the module's API.
4987
Brett Cannon7b96f072008-08-18 00:41:11 +00004988- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4989
Brett Cannon46225e72008-08-18 00:36:52 +00004990- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004992- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4993
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004994- Issue #3575: Incremental decoder's decode function now takes bytearray
4995 by using 's*' instead of 't#'.
4996
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004997- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004998 fails unicode conversion on 2nd parameter. (windows only)
4999
Georg Brandl222e2082010-08-01 22:27:39 +00005000- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005001 in a redirect.
5002
Brett Cannonabe423e2008-08-16 21:47:07 +00005003- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005004 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005005
Facundo Batistaeb90b782008-08-16 14:44:07 +00005006- Issue #2776: fixed small issue when handling an URL with double slash
5007 after a 302 response in the case of not going through a proxy.
5008
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005009- Issue #2676: in the email package, content-type parsing was hanging on
5010 pathological input because of quadratic or exponential behaviour of a
5011 regular expression.
5012
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005013- Issue #3476: binary buffered reading through the new "io" library is now
5014 thread-safe.
5015
Brett Cannonbf3157b2008-08-14 05:00:03 +00005016- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5017 since mimetools itself is deprecated. Because modules are cached, all
5018 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5019
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005020- Issue #3134: shutil referenced undefined WindowsError symbol.
5021
Robert Schuppenies14646332008-08-10 11:01:53 +00005022- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5023 menu entries were not deleted.
5024
Brett Cannon83e81842008-08-09 23:30:55 +00005025- Copied the implementation of reduce() to _functools.reduce() to have a
5026 version that did not raise a DeprecationWarning under -3.
5027
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005028- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5029 a MemoryError rather than silently stop the iteration.
5030
Guido van Rossum59ce9012008-08-09 14:55:34 +00005031- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5032 to _sre.compile() will now be rejected. This should not affect anybody
5033 since the re.compile() function never generates invalid re-bytecode.
5034
Skip Montanaroa032bf42008-08-08 22:52:51 +00005035- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5036 upon first access it can be automatically initialized from the csv file if
5037 it wasn't initialized during instantiation.
5038
Brett Cannon3aa2a492008-08-06 22:28:09 +00005039- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5040 the reload() built-in has been removed.
5041
Brett Cannon7e30b672008-08-04 21:52:25 +00005042- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005043 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005054 asking for a specific length. This problem only affected files opened
5055 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005056

Mark Dickinson64b7e502008-07-16 09:40:03 +00005117- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5118 produced a ValueError instead of giving the correct float.
5119
Eric Smitha5fa5a22008-07-16 00:11:49 +00005120- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5121 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5122
Mark Dickinson7103aa42008-07-15 19:08:33 +00005123- Issue #3008: the float type has a new instance method 'float.hex'
5124 and a new class method 'float.fromhex' to convert floating-point
5125 numbers to and from hexadecimal strings, respectively.
5126
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005127- Issue #2235: __hash__ is once again inherited by default. To allow
5128 collections.Hashable to remain meaningful in the presence of the
5129 default hash implementation (object.__hash__), it is now possible
5130 to explicit block inheritance of hash by setting __hash__=None at
5131 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5132 level.
5133
Nick Coghlanb028f502008-07-13 14:52:36 +00005134- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5135 the parent module cannot be found while performing an absolute import.
5136 This means that an incorrectly defined __package__ attribute will
5137 now only prevent relative imports in that module rather than causing
5138 all imports from that module to fail.
5139
Nick Coghlan14ff9942008-07-08 14:21:42 +00005140- Issue #2517: Allow unicode messages in Exceptions again by correctly

5150 another thread's dictionary.
5151
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005152- Issue #3004: Minor change to slice.indices(): the start and stop
5153 arguments are now treated identically, making the behaviour easier
5154 to describe and understand. For example, slice(None, -10,
5155 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5156 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5157 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00005159- Issue #3219: Calling a function with repeated keyword arguments,
5160 f(a=2, a=23), would not cause a syntax error. This was a regression
5161 from 2.4 caused by the switch to the new compiler.

5200 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005201 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005673- Issue #1631171: Re-implement the 'warnings' module in C (the
5674 original Python code has been kept as backup). This will allow for
5675 using the 'warning's machinery in such places as the parser where
5676 use of pure Python code is not possible. Both the ``showarning()``
5677 and ``formatwarning()`` gain an optional 'line' argument which is
5678 not called by default for backwards-compatibility reasons. Setting
5679 ``warnings.showwarning()`` to an implementation that lacks support
5680 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005743- Issue #2550: The approach used by client/server code for obtaining
5744 ports to listen on in network-oriented tests has been refined in an
5745 effort to facilitate running multiple instances of the entire
5746 regression test suite in parallel without issue.
5747 test_support.bind_port() has been fixed such that it will always
5748 return a unique port -- which wasn't always the case with the
5749 previous implementation, especially if socket options had been set
5750 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5751 new implementation of bind_port() will actually raise an exception
5752 if it is passed an AF_INET/SOCK_STREAM socket with either the
5753 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5754 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5755 the socket it's been passed. This currently only applies to
5756 Windows. This option prevents any other sockets from binding to the
5757 host/port we've bound to, thus removing the possibility of the
5758 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5759 when a second SOCK_STREAM socket binds and accepts to a host/port
5760 that's already been bound by another socket. The optional preferred
5761 port parameter to bind_port() has been removed. Under no
5762 circumstances should tests be hard coding ports!
5763
5764 test_support.find_unused_port() has also been introduced, which will
5765 pass a temporary socket object to bind_port() in order to obtain an
5766 unused port. The temporary socket object is then closed and
5767 deleted, and the port is returned. This method should only be used
5768 for obtaining an unused port in order to pass to an external program
5769 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5770 a parameter to a server-oriented class that doesn't give you direct
5771 access to the underlying socket used.
5772
5773 Finally, test_support.HOST has been introduced, which should be used
5774 for the host argument of any relevant socket calls (i.e. bind and
5775 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005776
5777 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005778 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005779 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5780 test_asynchat and test_socket_ssl.
5781
Georg Brandl3ee81df2008-05-17 18:14:43 +00005782 It is now possible for multiple instances of the regression test
5783 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006062- Added the future_builtins module, which contains hex() and oct().
6063 These are the PEP 3127 version of these functions, designed to be
6064 compatible with the hex() and oct() builtins from Python 3.0. They
6065 differ slightly in their output formats from the existing, unchanged
6066 Python 2.6 builtins. The expected usage of the future_builtins
6067 module is:
6068 from future_builtins import hex, oct
6069
Eric Smith7ef40bf2008-02-20 23:34:22 +00006070- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6071 exponents for exponents with absolute value < 100. Follows C99
6072 standard. This is a change on Windows, which would use 3 digits.
6073 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6074 so that any alterations it does to the resulting string will be
6075 available in stringlib/formatter.h (for float.__format__).
6076
Eric Smith5a3c1352008-02-19 13:21:56 +00006077- Implemented PEP 3101, Advanced String Formatting. This adds a new
6078 builtin format(); a format() method for str and unicode; a
6079 __format__() method to object, str, unicode, int, long, float, and
6080 datetime; the class string.Formatter; and the C API
6081 PyObject_Format().
6082
Georg Brandl3ee81df2008-05-17 18:14:43 +00006083- Fixed several potential crashes, all caused by specially crafted
6084 __del__ methods exploiting objects in temporarily inconsistent
6085 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006086
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006087- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006088 prevent a possible crash: an Abstract Base Class would try to access
6089 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006090

Georg Brandl3ee81df2008-05-17 18:14:43 +00006094- Clear all free lists during a gc.collect() of the highest generation
6095 in order to allow pymalloc to free more arenas. Python may give back
6096 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006097
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098- Issue #2045: Fix an infinite recursion triggered when printing a
6099 subclass of collections.defaultdict, if its default_factory is set
6100 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006101
Christian Heimesf75dbef2008-02-08 00:11:31 +00006102- Fixed a minor memory leak in dictobject.c. The content of the free
6103 list was not freed on interpreter shutdown.
6104
Georg Brandl21e99f42010-03-07 15:23:59 +00006105- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006106 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006107
Georg Brandl3ee81df2008-05-17 18:14:43 +00006108- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6109 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006110 to compact the internal free lists of pre-allocted ints and floats.
6111
Georg Brandl3ee81df2008-05-17 18:14:43 +00006112- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6113 calls. Python expected the return type int but the fork familie
6114 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006115
Georg Brandl3ee81df2008-05-17 18:14:43 +00006116- Issue #1678380: Fix a bug that identifies 0j and -0j when they

6126 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006127
Georg Brandl3ee81df2008-05-17 18:14:43 +00006128- Patch #1473257: generator objects gain a gi_code attribute. This is
6129 the same object as the func_code attribute of the function that
6130 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006131
Georg Brandl3ee81df2008-05-17 18:14:43 +00006132- Issue #1920: "while 0" statements were completely removed by the
6133 compiler, even in the presence of an "else" clause, which is
6134 supposed to be run when the condition is false. Now the compiler
6135 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006136
Guido van Rossumeead05f2008-01-24 18:21:02 +00006137- A few crashers fixed: weakref_in_del.py (issue #1377858);
6138 loosing_dict_ref.py (issue #1303614, test67.py);
6139 borrowed_ref_[34].py (not in tracker).
6140
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006141- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006142 suppressed while an extension is loaded by calling SetErrorMode in
6143 dynload_win.c. The error is still reported properly.
6144
Georg Brandl3ee81df2008-05-17 18:14:43 +00006145- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006146 several extension methods and modules do not work without unicode
6147 support.
6148
Georg Brandl26543b12008-01-21 18:36:51 +00006149- Issue #1882: when compiling code from a string, encoding cookies in the
6150 second line of code were not always recognized correctly.
6151
Georg Brandl14404b62008-01-19 19:27:05 +00006152- Issue #1679: "0x" was taken as a valid integer literal.
6153
Georg Brandl6caad7d2008-01-26 14:19:22 +00006154- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006155 added.
6156
Christian Heimesc94e2b52008-01-14 04:13:37 +00006157- sys.float_info / PyFloat_GetInfo: The floating point information
6158 object was converted from a dict to a specialized structseq object.
6159
Georg Brandl3ee81df2008-05-17 18:14:43 +00006160- Patch #1816: Added sys.flags structseq. It exposes the status of
6161 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006162
Georg Brandl3ee81df2008-05-17 18:14:43 +00006163- Objects/structseq.c: Implemented new structseq representation. The
6164 patch makes structseqs (e.g. the return value of os.stat) more
6165 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006166
Georg Brandl3ee81df2008-05-17 18:14:43 +00006167- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006179- Improve some exception messages when Windows fails to load an
6180 extension module. Now we get for example '%1 is not a valid Win32
6181 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006188- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006189 and INF. float("nan"), float("inf") and float("-inf") now work on
6190 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006192- Compiler now generates simpler and faster code for dictionary
6193 literals. The oparg for BUILD_MAP now indicates an estimated
6194 dictionary size. There is a new opcode, STORE_MAP, for adding
6195 entries to the dictionary.

6207
Nick Coghlanef01d822007-12-03 12:55:17 +00006208- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00006224- Patch #1739468: Directories and zipfiles containing a __main__.py
6225 file can now be directly executed by passing their name to the
6226 interpreter. The directory/zipfile is automatically inserted as the
6227 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006229- Issue #1265: Fix a problem with sys.settrace, if the tracing
6230 function uses a generator expression when at the same time the
6231 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006232
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006233- sets and frozensets now have an isdisjoint() method.

6238
Georg Brandl21e99f42010-03-07 15:23:59 +00006239- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006240 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6241 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006242
Georg Brandl3ee81df2008-05-17 18:14:43 +00006243- Issue #1686386: Tuple's tp_repr did not take into account the
6244 possibility of having a self-referential tuple, which is possible
6245 from C code. Nor did object's tp_str consider that a type's tp_str
6246 could do something that could lead to an inifinite recursion.
6247 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6248 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006249
Georg Brandl3ee81df2008-05-17 18:14:43 +00006250- Issue #1164: It was possible to trigger deadlock when using the
6251 'print' statement to write to a file since the GIL was not released
6252 as needed. Now PyObject_Print() does the right thing along with
6253 various tp_print implementations of the built-in types and those in
6254 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006255
Georg Brandl3ee81df2008-05-17 18:14:43 +00006256- Issue #1147: Exceptions were directly allowing string exceptions in
6257 their throw() method even though string exceptions no longer
6258 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006260- Issue #1096: Prevent a segfault from getting the repr of a very
6261 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006262
Brett Cannon1e534b52007-09-07 04:18:30 +00006263- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006264 PyObject_Call() never calling back out to Python code to trigger
6265 recursion depth updates/checks. Required the creation of a static
6266 RuntimeError instance in case normalizing an exception put the
6267 recursion check value past its limit. Fixes crashers
6268 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006269
Georg Brandl3ee81df2008-05-17 18:14:43 +00006270- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006283- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006284 __*__ attributes. (Some already existed, e.g., __doc__ and
6285 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006286
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006287- Add -3 option to the interpreter to warn about features that are
6288 deprecated and will be changed/removed in Python 3.0.
6289
Georg Brandl2134e752007-05-21 20:34:16 +00006290- Patch #1686487: you can now pass any mapping after '**' in function
6291 calls.
6292
Collin Winter62903052007-05-18 23:11:24 +00006293- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006294 "except E as target:". This is to provide forwards compatibility
6295 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006296
Brett Cannon229cee22007-05-05 01:34:02 +00006297- Deprecate BaseException.message as per PEP 352.
6298
Georg Brandl3ee81df2008-05-17 18:14:43 +00006299- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006300 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006301
Vinay Sajip8549ce32007-05-06 17:53:37 +00006302- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006303 setting a plain string, ie don't expand to single letter identifiers.
6304
Raymond Hettinger13936692007-04-11 18:40:58 +00006305- Request #1191699: Slices can now be pickled.
6306
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006307- Request #1193128: str.translate() now allows a None argument for
6308 translations that only remove characters without re-mapping the
6309 remaining characters.
6310
Georg Brandl5cb76c12007-03-21 09:00:39 +00006311- Patch #1682205: a TypeError while unpacking an iterable is no longer
6312 masked by a generic one with the message "unpack non-sequence".
6313
Neal Norwitzaa754b72007-03-21 06:39:48 +00006314- Remove unused file Python/fmod.c.
6315
Guido van Rossum143b5642007-03-23 04:58:42 +00006316- Bug #1683368: The object.__init__() and object.__new__() methods are
6317 now stricter in rejecting excess arguments. The only time when
6318 either allows excess arguments is when it is not overridden and the
6319 other one is. For backwards compatibility, when both are
6320 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006321 warning later). Also, type.__init__() insists on the same signature
6322 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006323
Georg Brandl3ee81df2008-05-17 18:14:43 +00006324- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6325 object to complex using its __complex__() method before falling back
6326 to the __float__() method. Therefore, the functions in the cmath
6327 module now can operate on objects that define a __complex__()
6328 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006329
Georg Brandl3ee81df2008-05-17 18:14:43 +00006330- Patch #1623563: allow __class__ assignment for classes with
6331 __slots__. The old and the new class are still required to have the
6332 same slot names.

6338 ``object.__reduce_ex__()`` is called with an object that is faking
6339 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006340
Georg Brandl3ee81df2008-05-17 18:14:43 +00006341- Patch #1680015: Don't modify __slots__ tuple if it contains an

6345
Georg Brandl7b9c5552007-03-12 14:30:05 +00006346- Bug #1678647: write a newline after printing an exception in any
6347 case, even when converting the value to a string failed.
6348
Georg Brandl871f1bc2007-03-12 13:17:36 +00006349- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006350 its argument, if it exists. If not, it will work like before. This
6351 allows customizing the output of dir() in the presence of a
6352 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006353
Collin Winter276887b2007-03-12 16:11:39 +00006354- Patch #922167: Python no longer segfaults when faced with infinitely
6355 self-recursive reload() calls (as reported by bug #742342).
6356
Georg Brandl3ee81df2008-05-17 18:14:43 +00006357- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006360- Patch #1491866: change the complex() constructor to allow
6361 parthensized forms. This means complex(repr(x)) now works instead of
6362 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006363
Georg Brandlaa2321b2007-03-07 00:40:28 +00006364- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006365 makes the filenames the warning module prints much more sensible
6366 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006367

6369 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006370 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00006379- Patch #1674228: when assigning a slice (old-style), check for the
6380 sq_ass_slice instead of the sq_slice slot.
6381
Georg Brandl3ee81df2008-05-17 18:14:43 +00006382- When printing an unraisable error, don't print exceptions. before
6383 the name. This duplicates the behavior whening normally printing
6384 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006952 are set for invalid interpolation sequences that would lead to

7009 TestCase and TestSuite subclasses (not instances) are no longer
7010 accepted in TestSuite.addTest(). This should cause no
7011 incompatibility since it never made sense with ordinary subclasses
7012 -- the failure just occurred later, with a more cumbersome
7013 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007300 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007401- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00007402 time so that opening a database previously created with the DB_DUP
7403 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7404 opens. Specifically: dictionary assignment to a DB object will
7405 replace all values for a given key when the database allows
7406 duplicate values. DB users should use DB.put(k, v) when they want
7407 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007687 periodic threadstate and signal checking in tight loops. By
7688 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00007746
Georg Brandl3ee81df2008-05-17 18:14:43 +00007747- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7748 to ``PyTuple_SetItem``, it can be used to populate a brand new

7761
Georg Brandl3ee81df2008-05-17 18:14:43 +00007762- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7763 of w# format code incorrectly truncated the length to an int, even
7764 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7765 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007766
Georg Brandl3ee81df2008-05-17 18:14:43 +00007767- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7789 outside of pystate.c and should not be necessary.
7790
Georg Brandl3ee81df2008-05-17 18:14:43 +00007791- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7792 absolute imports. In earlier versions they might have used relative
7793 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007794
Georg Brandl3ee81df2008-05-17 18:14:43 +00007795- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7796 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007797
Georg Brandl3ee81df2008-05-17 18:14:43 +00007798- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7808 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007809

Georg Brandl3ee81df2008-05-17 18:14:43 +00007823- Removed the macfs module. It had been deprecated since Python 2.5.
7824 This lead to the deprecation of macostools.touched() as it relied
