28 processing: any non-float non-integer argument is now converted to

1485What's New in Python 2.6.1
1486==========================
1487
1488*Release date: 04-Dec-2008*
1489
1490Core and Builtins
1491-----------------
1492
1493- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1494 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1495 instead of throwing a MemoryError.
1496
1497- Issue #4367: Python would segfault during compiling when the unicodedata
1498 module couldn't be imported and \N escapes were present.
1499
1500- Issue #4348: Some bytearray methods returned that didn't cause any change to
1501 the bytearray, returned the same bytearray instead of a copy.
1502
1503- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1504
1505- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1506
1507- Issue #4048: The parser module now correctly validates relative imports.
1508
1509- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1510 exec statement.
1511
1512- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1513 method does not return iterators for the 4th and 5th items.
1514
1515- Issue #4209: Enabling unicode_literals and the print_function in the same
1516 __future__ import didn't work.
1517
1518- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1519 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1520 really executed because I cannot move to such directory on win2k)
1521
1522- Issue #4069: When set.remove(element) is used with a set element, the element
1523 is temporarily replaced with an equivalent frozenset. But the eventual
1524 KeyError would always report the empty frozenset([]) as the missing key. Now
1525 it correctly refers to the initial element.
1526
1527- Fixed C99 style comments in several files. Python is now C89 compatible
1528 again.

1676
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001677- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1678 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1679 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1680 ``printf`` function, whereas PyString_FromFormat has an independent
1681 implementation and uses "%zd" on all platforms for size_t values.
1682 This makes a difference on win64, where ``printf`` needs "%Id" to display
1683 64bit values.

1689 object; previously an int would be returned for small values. the __long__
1690 method is allowed to return either an int or a long, but the behaviour of
1691 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001693- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001699 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001700 was correctly parsed but parsing of subsequent arguments failed.
1701
Vinay Sajip35e3b032008-09-01 14:33:59 +00001702- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001703 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1704 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1705 when given a tuple of classes as second argument, were looking up
1706 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1707 type object.
1708
Neal Norwitz18aa3882008-08-24 05:04:52 +00001709- Fix crashes on memory allocation failure found with failmalloc.

1850
Guido van Rossumf8402962008-08-20 15:01:50 +00001851- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1852 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1853 extensions do not automatically benefit from the class attribute
1854 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1855 to their tp_flags field if they care. This is a backwards
1856 compatibility feature; in 3.0, all types will use the cache by
1857 default.
1858
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001859- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00001872- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1873 ValueError consistently across platforms.
1874
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001875- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1876 (64bit Unix, for example), unichr() would truncate its argument and return
1877 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1878
Neal Norwitze7d8be82008-07-31 17:17:14 +00001879- Apply security patches from Apple.
1880
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001881- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1882 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1883
Antoine Pitrou92f82162008-07-25 22:22:08 +00001884- Issue #1819: function calls with several named parameters are now on
1885 average 35% faster (as measured by pybench).
1886
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001887- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1888 the python debugger steps into a class statement: the free variables (local
1889 variables defined in an outer scope) would be deleted from the outer scope.
1890
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001891- Issue #2620: Overflow checking when allocating or reallocating memory
1892 was not always being done properly in some python types and extension
1893 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1894 all been updated to perform better checks and places in the code that
1895 would previously leak memory on the error path when such an allocation
1896 failed have been fixed.

1902
Benjamin Petersone977ad42008-08-20 01:42:01 +00001903- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1904 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1905
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001906- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1907 version reported by these tools does not necessarily follow the python
1908 version numbering scheme, so the module is less strict when parsing it.
1909
Nick Coghlanf70385a2008-08-18 12:42:46 +00001910- Issue #2235: Added Py3k warnings for types which will become unhashable
1911 under the stricter __hash__ inheritance rules in 3.0. Several types
1912 which did not meet the rules for hash invariants and were already
1913 unhashable in 3.0 have now been explicitly flagged as unhashable in
1914 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1915 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1916
Brett Cannon88f801d2008-08-18 00:46:22 +00001917- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1939 after a 302 response in the case of not going through a proxy.
1940
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001941- Issue #2676: in the email package, content-type parsing was hanging on
1942 pathological input because of quadratic or exponential behaviour of a
1943 regular expression.
1944
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001945- Issue #3476: binary buffered reading through the new "io" library is now
1946 thread-safe.
1947
Brett Cannonbf3157b2008-08-14 05:00:03 +00001948- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1949 since mimetools itself is deprecated. Because modules are cached, all
1950 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1951
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001952- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001954- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1955 menu entries were not deleted.
1956
Brett Cannon83e81842008-08-09 23:30:55 +00001957- Copied the implementation of reduce() to _functools.reduce() to have a
1958 version that did not raise a DeprecationWarning under -3.
1959
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001960- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1961 a MemoryError rather than silently stop the iteration.
1962
Guido van Rossum59ce9012008-08-09 14:55:34 +00001963- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1964 to _sre.compile() will now be rejected. This should not affect anybody
1965 since the re.compile() function never generates invalid re-bytecode.
1966
Skip Montanaroa032bf42008-08-08 22:52:51 +00001967- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1968 upon first access it can be automatically initialized from the csv file if
1969 it wasn't initialized during instantiation.
1970
Brett Cannon3aa2a492008-08-06 22:28:09 +00001971- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1972 the reload() built-in has been removed.
1973
Brett Cannon7e30b672008-08-04 21:52:25 +00001974- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001975 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1983 raised an AttributeError.
1984
Benjamin Peterson01a24322008-07-28 23:35:27 +00001985- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001986 asking for a specific length. This problem only affected files opened
1987 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001988

2011
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002012- Issue #3394: zipfile.writestr sets external attributes when passed a
2013 file name rather than a ZipInfo instance, so files are extracted with
2014 mode 0600 rather than 000 under Unix.
2015
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002016- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2017 argument in python 2.5, this broke code that subclassed Popen to include its

2027
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002028- Issue #2235: the C API function PyObject_HashNotImplemented and its
2029 interaction with the tp_hash slot (added in 2.6b2) are now documented
2030
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002031- Issue #643841: The language reference now provides more detailed
2032 coverage of the lookup process for special methods. The disclaimers
2033 regarding lack of coverage of new-style classes have also been
2034 removed, since the coverage is now fairly reasonable.

2038================================
2039
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002040*Release date: 17-Jul-2008*
2041
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002042Core and Builtins
2043-----------------
2044
Georg Brandl3e483f62008-07-16 22:57:41 +00002045- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2046 its methods now allow for items objects that can be converted to
2047 an integer using operator.index().
2048
Mark Dickinson64b7e502008-07-16 09:40:03 +00002049- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2050 produced a ValueError instead of giving the correct float.
2051
Eric Smitha5fa5a22008-07-16 00:11:49 +00002052- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2053 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2054
Mark Dickinson7103aa42008-07-15 19:08:33 +00002055- Issue #3008: the float type has a new instance method 'float.hex'
2056 and a new class method 'float.fromhex' to convert floating-point
2057 numbers to and from hexadecimal strings, respectively.
2058
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002059- Issue #2235: __hash__ is once again inherited by default. To allow
2060 collections.Hashable to remain meaningful in the presence of the
2061 default hash implementation (object.__hash__), it is now possible
2062 to explicit block inheritance of hash by setting __hash__=None at
2063 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2064 level.
2065
Nick Coghlanb028f502008-07-13 14:52:36 +00002066- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2067 the parent module cannot be found while performing an absolute import.
2068 This means that an incorrectly defined __package__ attribute will
2069 now only prevent relative imports in that module rather than causing
2070 all imports from that module to fail.
2071
Nick Coghlan14ff9942008-07-08 14:21:42 +00002072- Issue #2517: Allow unicode messages in Exceptions again by correctly
2073 bypassing the instance dictionary when looking up __unicode__ on
2074 new-style classes.
2075
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002076- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2077 set to a custom object whose write() method happens to install
2078 another file in sys.stdout.
2079
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002080- Issue #3088: Corrected a race condition in classes derived from
2081 threading.local: the first member set by a thread could be saved in
2082 another thread's dictionary.
2083
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002084- Issue #3004: Minor change to slice.indices(): the start and stop
2085 arguments are now treated identically, making the behaviour easier
2086 to describe and understand. For example, slice(None, -10,
2087 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2088 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2089 10, -1).
2090
Georg Brandl278fc502008-07-19 12:46:12 +00002091- Issue #3219: Calling a function with repeated keyword arguments,
2092 f(a=2, a=23), would not cause a syntax error. This was a regression
2093 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002094
Georg Brandl278fc502008-07-19 12:46:12 +00002095- Issue #2862: Make int and float freelist management consistent with
2096 other freelists. Changes their CompactFreeList apis into
2097 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002098

2100-------
2101
Thomas Heller57adf222008-08-14 19:10:48 +00002102- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2103 api functions without holding the GIL, which could lead to a fatal
2104 error when they failed.
2105
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002106- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2115 ForkingPickler.register() to resolve conflict with ctypes.
2116
Vinay Sajip51e65192008-07-18 09:01:10 +00002117- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00002119- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2120 a valid dlerror() message.
2121
Thomas Heller2bad6572008-07-15 17:19:50 +00002122- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2123 incomplete structure was created.
2124
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002125- Issue #3339: dummy_thread.acquire() should not return None.
2126
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002127- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2128
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002129- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002130
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002131- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2132 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002133 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002134 content-length. The problem had been corrected in the 2.4 branch, but never
2135 merged into trunk.
2136
Georg Brandle78fbcc2008-07-05 10:13:36 +00002137- Issue #2663: add filtering capability to shutil.copytree().

2142
2143- Issue #1746: Correct handling of zipfile archive comments (previously
2144 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002145 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002146
Vinay Sajip51e65192008-07-18 09:01:10 +00002147- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002148 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002149
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002150- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2151 handling is now the same as that of other special attributes like __name__).
2152
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002153- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00002543 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002544
2545 This is controlled by the configure argument ``--with-universal-archs``:
2546
2547 - ``--with-universal-archs=all``: install 4-way universal
2548
2549 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2550
2551 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2552
2553 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002605- Issue #1631171: Re-implement the 'warnings' module in C (the
2606 original Python code has been kept as backup). This will allow for
2607 using the 'warning's machinery in such places as the parser where
2608 use of pure Python code is not possible. Both the ``showarning()``
2609 and ``formatwarning()`` gain an optional 'line' argument which is
2610 not called by default for backwards-compatibility reasons. Setting
2611 ``warnings.showwarning()`` to an implementation that lacks support
2612 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002675- Issue #2550: The approach used by client/server code for obtaining
2676 ports to listen on in network-oriented tests has been refined in an
2677 effort to facilitate running multiple instances of the entire
2678 regression test suite in parallel without issue.
2679 test_support.bind_port() has been fixed such that it will always
2680 return a unique port -- which wasn't always the case with the
2681 previous implementation, especially if socket options had been set
2682 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2683 new implementation of bind_port() will actually raise an exception
2684 if it is passed an AF_INET/SOCK_STREAM socket with either the
2685 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2686 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2687 the socket it's been passed. This currently only applies to
2688 Windows. This option prevents any other sockets from binding to the
2689 host/port we've bound to, thus removing the possibility of the
2690 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2691 when a second SOCK_STREAM socket binds and accepts to a host/port
2692 that's already been bound by another socket. The optional preferred
2693 port parameter to bind_port() has been removed. Under no
2694 circumstances should tests be hard coding ports!
2695
2696 test_support.find_unused_port() has also been introduced, which will
2697 pass a temporary socket object to bind_port() in order to obtain an
2698 unused port. The temporary socket object is then closed and
2699 deleted, and the port is returned. This method should only be used
2700 for obtaining an unused port in order to pass to an external program
2701 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2702 a parameter to a server-oriented class that doesn't give you direct
2703 access to the underlying socket used.
2704
2705 Finally, test_support.HOST has been introduced, which should be used
2706 for the host argument of any relevant socket calls (i.e. bind and
2707 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002708
2709 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002711 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2712 test_asynchat and test_socket_ssl.
2713
Georg Brandl3ee81df2008-05-17 18:14:43 +00002714 It is now possible for multiple instances of the regression test
2715 suite to run in parallel without issue.

2981Core and builtins
2982-----------------
2983
Fred Drakea8ee94b2008-03-01 02:45:07 +00002984- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002985 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002986
Georg Brandlad61bc82008-02-23 15:11:18 +00002987- Issue #2067: file.__exit__() now calls subclasses' close() method.
2988
2989- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002990
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002991- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002992 issue 215555 for a discussion.
2993
Eric Smitha73fbe72008-02-23 03:09:44 +00002994- Added the future_builtins module, which contains hex() and oct().
2995 These are the PEP 3127 version of these functions, designed to be
2996 compatible with the hex() and oct() builtins from Python 3.0. They
2997 differ slightly in their output formats from the existing, unchanged
2998 Python 2.6 builtins. The expected usage of the future_builtins
2999 module is:
3000 from future_builtins import hex, oct
3001
Eric Smith7ef40bf2008-02-20 23:34:22 +00003002- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3003 exponents for exponents with absolute value < 100. Follows C99
3004 standard. This is a change on Windows, which would use 3 digits.
3005 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3006 so that any alterations it does to the resulting string will be
3007 available in stringlib/formatter.h (for float.__format__).
3008
Eric Smith5a3c1352008-02-19 13:21:56 +00003009- Implemented PEP 3101, Advanced String Formatting. This adds a new
3010 builtin format(); a format() method for str and unicode; a
3011 __format__() method to object, str, unicode, int, long, float, and
3012 datetime; the class string.Formatter; and the C API
3013 PyObject_Format().
3014
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015- Fixed several potential crashes, all caused by specially crafted
3016 __del__ methods exploiting objects in temporarily inconsistent
3017 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003018
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003019- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020 prevent a possible crash: an Abstract Base Class would try to access
3021 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003022
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023- Fixed repr() and str() of complex numbers with infinity or nan as
3024 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003025
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026- Clear all free lists during a gc.collect() of the highest generation
3027 in order to allow pymalloc to free more arenas. Python may give back
3028 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Issue #2045: Fix an infinite recursion triggered when printing a
3031 subclass of collections.defaultdict, if its default_factory is set
3032 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003033
Christian Heimesf75dbef2008-02-08 00:11:31 +00003034- Fixed a minor memory leak in dictobject.c. The content of the free
3035 list was not freed on interpreter shutdown.
3036
Georg Brandl5a7eca12010-03-21 19:29:04 +00003037- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003038 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3041 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003042 to compact the internal free lists of pre-allocted ints and floats.
3043
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3045 calls. Python expected the return type int but the fork familie
3046 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003047
Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3049 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003050
Georg Brandl3ee81df2008-05-17 18:14:43 +00003051- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3052 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3055 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3058 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003059
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060- Patch #1473257: generator objects gain a gi_code attribute. This is
3061 the same object as the func_code attribute of the function that
3062 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Issue #1920: "while 0" statements were completely removed by the
3065 compiler, even in the presence of an "else" clause, which is
3066 supposed to be run when the condition is false. Now the compiler
3067 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003068
Guido van Rossumeead05f2008-01-24 18:21:02 +00003069- A few crashers fixed: weakref_in_del.py (issue #1377858);
3070 loosing_dict_ref.py (issue #1303614, test67.py);
3071 borrowed_ref_[34].py (not in tracker).
3072
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003073- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003074 suppressed while an extension is loaded by calling SetErrorMode in
3075 dynload_win.c. The error is still reported properly.
3076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003078 several extension methods and modules do not work without unicode
3079 support.
3080
Georg Brandl26543b12008-01-21 18:36:51 +00003081- Issue #1882: when compiling code from a string, encoding cookies in the
3082 second line of code were not always recognized correctly.
3083
Georg Brandl14404b62008-01-19 19:27:05 +00003084- Issue #1679: "0x" was taken as a valid integer literal.
3085
Georg Brandl6caad7d2008-01-26 14:19:22 +00003086- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003087 added.
3088
Christian Heimesc94e2b52008-01-14 04:13:37 +00003089- sys.float_info / PyFloat_GetInfo: The floating point information
3090 object was converted from a dict to a specialized structseq object.
3091
Georg Brandl3ee81df2008-05-17 18:14:43 +00003092- Patch #1816: Added sys.flags structseq. It exposes the status of
3093 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Objects/structseq.c: Implemented new structseq representation. The
3096 patch makes structseqs (e.g. the return value of os.stat) more
3097 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003098
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Patch #1700288: added a type attribute cache that caches method
3100 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003101
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003102- Bug #1776: __import__() no longer accepts filenames on any platform.
3103 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003104
Georg Brandlaed6c662008-01-07 17:25:53 +00003105- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3108 envvar and sys.dont_write_bytecode attribute. All these can be set
3109 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003110
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- Improve some exception messages when Windows fails to load an
3112 extension module. Now we get for example '%1 is not a valid Win32
3113 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003114
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3118 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003119
Christian Heimes0a8143f2007-12-18 23:22:54 +00003120- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121 and INF. float("nan"), float("inf") and float("-inf") now work on
3122 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Compiler now generates simpler and faster code for dictionary
3125 literals. The oparg for BUILD_MAP now indicates an estimated
3126 dictionary size. There is a new opcode, STORE_MAP, for adding
3127 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003128
Georg Brandl3ee81df2008-05-17 18:14:43 +00003129- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003134- Issue #1538: Avoid copying string in split/rsplit if the split char
3135 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003136
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003137- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003138 SystemError.
3139
Nick Coghlanef01d822007-12-03 12:55:17 +00003140- PEP 366: Allow explicit relative imports when executing modules

3142 __package__ attribute.
3143
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144- Issue #1402: Fix a crash on exit, when another thread is still
3145 running, and if the deallocation of its frames somehow calls the
3146 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003147

3152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Issue #1460: The utf-7 incremental decoder did not accept truncated
3154 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003155
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Patch #1739468: Directories and zipfiles containing a __main__.py
3157 file can now be directly executed by passing their name to the
3158 interpreter. The directory/zipfile is automatically inserted as the
3159 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Issue #1265: Fix a problem with sys.settrace, if the tracing
3162 function uses a generator expression when at the same time the
3163 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003164
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003165- sets and frozensets now have an isdisjoint() method.
3166
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003167- optimize the performance of builtin.sum().
3168
Neal Norwitz44f326e2007-10-05 05:29:17 +00003169- Fix warnings found by the new version of the Coverity checker.
3170
Georg Brandl5a7eca12010-03-21 19:29:04 +00003171- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3173 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003174
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Issue #1686386: Tuple's tp_repr did not take into account the
3176 possibility of having a self-referential tuple, which is possible
3177 from C code. Nor did object's tp_str consider that a type's tp_str
3178 could do something that could lead to an inifinite recursion.
3179 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3180 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Issue #1164: It was possible to trigger deadlock when using the
3183 'print' statement to write to a file since the GIL was not released
3184 as needed. Now PyObject_Print() does the right thing along with
3185 various tp_print implementations of the built-in types and those in
3186 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003187
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Issue #1147: Exceptions were directly allowing string exceptions in
3189 their throw() method even though string exceptions no longer
3190 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003191

Brett Cannon1e534b52007-09-07 04:18:30 +00003195- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196 PyObject_Call() never calling back out to Python code to trigger
3197 recursion depth updates/checks. Required the creation of a static
3198 RuntimeError instance in case normalizing an exception put the
3199 recursion check value past its limit. Fixes crashers
3200 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003201
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003215- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216 __*__ attributes. (Some already existed, e.g., __doc__ and
3217 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003218
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003219- Add -3 option to the interpreter to warn about features that are
3220 deprecated and will be changed/removed in Python 3.0.
3221
Georg Brandl2134e752007-05-21 20:34:16 +00003222- Patch #1686487: you can now pass any mapping after '**' in function
3223 calls.
3224
Collin Winter62903052007-05-18 23:11:24 +00003225- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226 "except E as target:". This is to provide forwards compatibility
3227 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003228
Brett Cannon229cee22007-05-05 01:34:02 +00003229- Deprecate BaseException.message as per PEP 352.
3230
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003232 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003233
Vinay Sajip8549ce32007-05-06 17:53:37 +00003234- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003235 setting a plain string, ie don't expand to single letter identifiers.
3236
Raymond Hettinger13936692007-04-11 18:40:58 +00003237- Request #1191699: Slices can now be pickled.
3238
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003239- Request #1193128: str.translate() now allows a None argument for
3240 translations that only remove characters without re-mapping the
3241 remaining characters.
3242
Georg Brandl5cb76c12007-03-21 09:00:39 +00003243- Patch #1682205: a TypeError while unpacking an iterable is no longer
3244 masked by a generic one with the message "unpack non-sequence".
3245

3247
Guido van Rossum143b5642007-03-23 04:58:42 +00003248- Bug #1683368: The object.__init__() and object.__new__() methods are
3249 now stricter in rejecting excess arguments. The only time when
3250 either allows excess arguments is when it is not overridden and the
3251 other one is. For backwards compatibility, when both are
3252 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003253 warning later). Also, type.__init__() insists on the same signature
3254 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3257 object to complex using its __complex__() method before falling back
3258 to the __float__() method. Therefore, the functions in the cmath
3259 module now can operate on objects that define a __complex__()
3260 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Patch #1623563: allow __class__ assignment for classes with
3263 __slots__. The old and the new class are still required to have the
3264 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003265

3270 ``object.__reduce_ex__()`` is called with an object that is faking
3271 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003272

3277
Georg Brandl7b9c5552007-03-12 14:30:05 +00003278- Bug #1678647: write a newline after printing an exception in any
3279 case, even when converting the value to a string failed.
3280
Georg Brandl871f1bc2007-03-12 13:17:36 +00003281- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003282 its argument, if it exists. If not, it will work like before. This
3283 allows customizing the output of dir() in the presence of a
3284 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003285
Collin Winter276887b2007-03-12 16:11:39 +00003286- Patch #922167: Python no longer segfaults when faced with infinitely
3287 self-recursive reload() calls (as reported by bug #742342).
3288

Georg Brandl3ee81df2008-05-17 18:14:43 +00003292- Patch #1491866: change the complex() constructor to allow
3293 parthensized forms. This means complex(repr(x)) now works instead of
3294 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003295
Georg Brandlaa2321b2007-03-07 00:40:28 +00003296- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297 makes the filenames the warning module prints much more sensible
3298 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003299
Georg Brandl49aafc92007-03-07 00:34:46 +00003300- Variant of patch #697613: don't exit the interpreter on a SystemExit
3301 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003302 variable is given, but break into the interactive interpreter just
3303 like on other exceptions or normal program exit.

3309 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003310
Georg Brandl0fca97a2007-03-05 22:28:08 +00003311- Patch #1674228: when assigning a slice (old-style), check for the
3312 sq_ass_slice instead of the sq_slice slot.
3313
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314- When printing an unraisable error, don't print exceptions. before
3315 the name. This duplicates the behavior whening normally printing
3316 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003317
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Bug #1377858: Fix the segfaulting of the interpreter when an object
3325 created a weakref on itself during a __del__ call for new-style
3326 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003940- unittest now verifies more of its assumptions. In particular,
3941 TestCase and TestSuite subclasses (not instances) are no longer
3942 accepted in TestSuite.addTest(). This should cause no
3943 incompatibility since it never made sense with ordinary subclasses
3944 -- the failure just occurred later, with a more cumbersome
3945 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4227 with RFC 3207 and forgets any knowledge obtained from the server not
4228 obtained from the TLS negotiation itself. Patch contributed by Bill
4229 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004230
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004232 that the SMTP.starttls() caller no longer needs to call ehlo()
4233 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234 does not claim to support starttls. Adds the
4235 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4316 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4317 silently miscode subclasses of those types. Now, it raises a
4318 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004319

Georg Brandl3ee81df2008-05-17 18:14:43 +00004334 time so that opening a database previously created with the DB_DUP
4335 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4336 opens. Specifically: dictionary assignment to a DB object will
4337 replace all values for a given key when the database allows
4338 duplicate values. DB users should use DB.put(k, v) when they want
4339 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004340

4346 characters with ASCII value less than 32. Also, it correctly quotes
4347 dots only if they occur on a single line, as opposed to the previous
4348 behavior of quoting dots if they are the second character of any
4349 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004350

Georg Brandl3ee81df2008-05-17 18:14:43 +00004674- Unified naming convention for free lists and their limits. All free
4675 lists in Object/ are named ``free_list``, the counter ``numfree``
4676 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4677 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004678
Georg Brandl3ee81df2008-05-17 18:14:43 +00004679- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4680 to ``PyTuple_SetItem``, it can be used to populate a brand new
4681 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004682
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004683- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004684
Georg Brandl3ee81df2008-05-17 18:14:43 +00004685- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4686 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4687 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004688
4689- Patch #1720595: add T_BOOL to the range of structmember types.
4690
4691- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4692 ``PyFloat_GetInfo()`` to the float API.
4693
Georg Brandl3ee81df2008-05-17 18:14:43 +00004694- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4695 of w# format code incorrectly truncated the length to an int, even
4696 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4697 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004698
Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4700 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004701
Georg Brandl3ee81df2008-05-17 18:14:43 +00004702- PEP 3123: Provide forward compatibility with Python 3.0, while
4703 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4704 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004705
Georg Brandl3ee81df2008-05-17 18:14:43 +00004706- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4707 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004708
4709- Patch #1733960: Allow T_LONGLONG to accept ints.
4710
4711- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4712
Christian Heimes000a0742008-01-03 22:16:32 +00004713- Added a new API function ``PyImport_ImportModuleNoBlock``.
4714
Georg Brandl6caad7d2008-01-26 14:19:22 +00004715- Bug #1637022: Prefix AST symbols with _Py_.
4716
4717- Fix some leftovers from the conversion from int to Py_ssize_t
4718 (relevant to strings and sequences of more than 2**31 items).
4719
4720- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4721 outside of pystate.c and should not be necessary.
4722
Georg Brandl3ee81df2008-05-17 18:14:43 +00004723- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4724 absolute imports. In earlier versions they might have used relative
4725 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004726
Georg Brandl3ee81df2008-05-17 18:14:43 +00004727- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4728 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004729
Georg Brandl3ee81df2008-05-17 18:14:43 +00004730- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4731 macro so it can be used as an expression.

4736
Georg Brandl3ee81df2008-05-17 18:14:43 +00004737- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4738 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4739 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4740 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004741
Georg Brandl3ee81df2008-05-17 18:14:43 +00004742- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4743 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00004753- buildtools now raises a DeprecationWarning.
4754
Georg Brandl3ee81df2008-05-17 18:14:43 +00004755- Removed the macfs module. It had been deprecated since Python 2.5.
4756 This lead to the deprecation of macostools.touched() as it relied
4757 solely on macfs and was a no-op under OS X.
