1761What's New in Python 2.6.1
1762==========================
1763
1764*Release date: 04-Dec-2008*
1765
1766Core and Builtins
1767-----------------
1768
1769- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1770 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1771 instead of throwing a MemoryError.
1772
1773- Issue #4367: Python would segfault during compiling when the unicodedata
1774 module couldn't be imported and \N escapes were present.
1775
1776- Issue #4348: Some bytearray methods returned that didn't cause any change to
1777 the bytearray, returned the same bytearray instead of a copy.
1778
1779- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1780
1781- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1782
1783- Issue #4048: The parser module now correctly validates relative imports.
1784
1785- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1786 exec statement.
1787
1788- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1789 method does not return iterators for the 4th and 5th items.
1790
1791- Issue #4209: Enabling unicode_literals and the print_function in the same
1792 __future__ import didn't work.
1793
1794- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1795 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1796 really executed because I cannot move to such directory on win2k)
1797
1798- Issue #4069: When set.remove(element) is used with a set element, the element
1799 is temporarily replaced with an equivalent frozenset. But the eventual
1800 KeyError would always report the empty frozenset([]) as the missing key. Now
1801 it correctly refers to the initial element.
1802
1803- Fixed C99 style comments in several files. Python is now C89 compatible
1804 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001951- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1952
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001953- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1954 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1955 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1956 ``printf`` function, whereas PyString_FromFormat has an independent
1957 implementation and uses "%zd" on all platforms for size_t values.
1958 This makes a difference on win64, where ``printf`` needs "%Id" to display
1959 64bit values.
1960
Benjamin Peterson97179b02008-09-09 20:55:01 +00001961- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1965 object; previously an int would be returned for small values. the __long__
1966 method is allowed to return either an int or a long, but the behaviour of
1967 float objects should not change to respect backward compatibility.
1968
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001969- Issue #3751: str.rpartition would perform a left-partition when called with
1970 a unicode argument.
1971
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001972- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001975 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001976 was correctly parsed but parsing of subsequent arguments failed.
1977
Vinay Sajip35e3b032008-09-01 14:33:59 +00001978- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001979 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1980 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1981 when given a tuple of classes as second argument, were looking up
1982 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1983 type object.
1984
Neal Norwitz18aa3882008-08-24 05:04:52 +00001985- Fix crashes on memory allocation failure found with failmalloc.
1986
1987- Fix memory leaks found with valgrind and update suppressions file.
1988
1989- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Brett Cannon672237d2008-09-09 00:49:16 +00002028 return a list or None rather than a custom object.
2029
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002030- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00002054 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2055 for catch_warnings() also led to an improvement in the raising of a

2125-----------------
2126
Guido van Rossumf8402962008-08-20 15:01:50 +00002127- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2128 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2129 extensions do not automatically benefit from the class attribute
2130 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2131 to their tp_flags field if they care. This is a backwards
2132 compatibility feature; in 3.0, all types will use the cache by
2133 default.
2134
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002135- Keyword arguments can now follow starred arguments. (``f(a, *args,
2136 keyword=23)`` is now valid syntax.)
2137
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002138- ctypes function pointers that are COM methods have a boolean True
2139 value again.

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002141- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2142 by denying s# to parse objects that have a releasebuffer procedure,
2143 and introducing s*.
2144
Georg Brandl1e13ea92008-08-11 09:07:59 +00002145- Issue #3537: Fix an assertion failure when an empty but presized dict
2146 object was stored in the freelist.
2147
Mark Dickinsonb6467572008-08-04 21:30:09 +00002148- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2149 ValueError consistently across platforms.
2150
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002151- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2152 (64bit Unix, for example), unichr() would truncate its argument and return
2153 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2154
Neal Norwitze7d8be82008-07-31 17:17:14 +00002155- Apply security patches from Apple.
2156
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002157- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2158 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2159
Antoine Pitrou92f82162008-07-25 22:22:08 +00002160- Issue #1819: function calls with several named parameters are now on

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002163- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2164 the python debugger steps into a class statement: the free variables (local
2165 variables defined in an outer scope) would be deleted from the outer scope.
2166
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002167- Issue #2620: Overflow checking when allocating or reallocating memory
2168 was not always being done properly in some python types and extension
2169 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2170 all been updated to perform better checks and places in the code that
2171 would previously leak memory on the error path when such an allocation
2172 failed have been fixed.

2178
Benjamin Petersone977ad42008-08-20 01:42:01 +00002179- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2180 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2181
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002182- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2183 version reported by these tools does not necessarily follow the python
2184 version numbering scheme, so the module is less strict when parsing it.
2185
Nick Coghlanf70385a2008-08-18 12:42:46 +00002186- Issue #2235: Added Py3k warnings for types which will become unhashable
2187 under the stricter __hash__ inheritance rules in 3.0. Several types
2188 which did not meet the rules for hash invariants and were already
2189 unhashable in 3.0 have now been explicitly flagged as unhashable in
2190 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2191 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2192
Brett Cannon88f801d2008-08-18 00:46:22 +00002193- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2194 imported into the module but exposed as part of the module's API.
2195

2219 regular expression.
2220
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002221- Issue #3476: binary buffered reading through the new "io" library is now
2222 thread-safe.
2223
Brett Cannonbf3157b2008-08-14 05:00:03 +00002224- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2225 since mimetools itself is deprecated. Because modules are cached, all
2226 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2227
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002228- Issue #3134: shutil referenced undefined WindowsError symbol.

2237 a MemoryError rather than silently stop the iteration.
2238
Guido van Rossum59ce9012008-08-09 14:55:34 +00002239- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2240 to _sre.compile() will now be rejected. This should not affect anybody
2241 since the re.compile() function never generates invalid re-bytecode.
2242
Skip Montanaroa032bf42008-08-08 22:52:51 +00002243- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2244 upon first access it can be automatically initialized from the csv file if
2245 it wasn't initialized during instantiation.
2246
Brett Cannon3aa2a492008-08-06 22:28:09 +00002247- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2248 the reload() built-in has been removed.
2249
Brett Cannon7e30b672008-08-04 21:52:25 +00002250- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002251 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2259 raised an AttributeError.
2260
Benjamin Peterson01a24322008-07-28 23:35:27 +00002261- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002262 asking for a specific length. This problem only affected files opened
2263 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002288- Issue #3394: zipfile.writestr sets external attributes when passed a
2289 file name rather than a ZipInfo instance, so files are extracted with
2290 mode 0600 rather than 000 under Unix.
2291
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002292- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2293 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002304- Issue #2235: the C API function PyObject_HashNotImplemented and its
2305 interaction with the tp_hash slot (added in 2.6b2) are now documented
2306
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002307- Issue #643841: The language reference now provides more detailed
2308 coverage of the lookup process for special methods. The disclaimers
2309 regarding lack of coverage of new-style classes have also been
2310 removed, since the coverage is now fairly reasonable.

2314================================
2315
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002316*Release date: 17-Jul-2008*
2317
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002318Core and Builtins
2319-----------------
2320
Georg Brandl3e483f62008-07-16 22:57:41 +00002321- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2322 its methods now allow for items objects that can be converted to
2323 an integer using operator.index().
2324
Mark Dickinson64b7e502008-07-16 09:40:03 +00002325- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2326 produced a ValueError instead of giving the correct float.
2327
Eric Smitha5fa5a22008-07-16 00:11:49 +00002328- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2329 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2330
Mark Dickinson7103aa42008-07-15 19:08:33 +00002331- Issue #3008: the float type has a new instance method 'float.hex'
2332 and a new class method 'float.fromhex' to convert floating-point
2333 numbers to and from hexadecimal strings, respectively.
2334
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002335- Issue #2235: __hash__ is once again inherited by default. To allow
2336 collections.Hashable to remain meaningful in the presence of the
2337 default hash implementation (object.__hash__), it is now possible
2338 to explicit block inheritance of hash by setting __hash__=None at
2339 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2340 level.
2341
Nick Coghlanb028f502008-07-13 14:52:36 +00002342- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2343 the parent module cannot be found while performing an absolute import.
2344 This means that an incorrectly defined __package__ attribute will
2345 now only prevent relative imports in that module rather than causing
2346 all imports from that module to fail.
2347
Nick Coghlan14ff9942008-07-08 14:21:42 +00002348- Issue #2517: Allow unicode messages in Exceptions again by correctly
2349 bypassing the instance dictionary when looking up __unicode__ on
2350 new-style classes.
2351
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002352- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2353 set to a custom object whose write() method happens to install
2354 another file in sys.stdout.
2355
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002356- Issue #3088: Corrected a race condition in classes derived from
2357 threading.local: the first member set by a thread could be saved in
2358 another thread's dictionary.
2359
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002360- Issue #3004: Minor change to slice.indices(): the start and stop
2361 arguments are now treated identically, making the behaviour easier
2362 to describe and understand. For example, slice(None, -10,
2363 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2364 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2365 10, -1).
2366
Georg Brandl278fc502008-07-19 12:46:12 +00002367- Issue #3219: Calling a function with repeated keyword arguments,
2368 f(a=2, a=23), would not cause a syntax error. This was a regression
2369 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002370
Georg Brandl278fc502008-07-19 12:46:12 +00002371- Issue #2862: Make int and float freelist management consistent with
2372 other freelists. Changes their CompactFreeList apis into
2373 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002374

2376-------
2377
Thomas Heller57adf222008-08-14 19:10:48 +00002378- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2379 api functions without holding the GIL, which could lead to a fatal
2380 error when they failed.
2381
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002382- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002390- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2391 ForkingPickler.register() to resolve conflict with ctypes.
2392
Vinay Sajip51e65192008-07-18 09:01:10 +00002393- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002394
Thomas Heller880f5292008-07-15 19:39:38 +00002395- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2396 a valid dlerror() message.
2397
Thomas Heller2bad6572008-07-15 17:19:50 +00002398- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2399 incomplete structure was created.
2400

2404
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002405- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002406
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002407- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2408 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002409 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002410 content-length. The problem had been corrected in the 2.4 branch, but never
2411 merged into trunk.
2412
Georg Brandle78fbcc2008-07-05 10:13:36 +00002413- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00002421 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002422
Vinay Sajip51e65192008-07-18 09:01:10 +00002423- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002424 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002425
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002426- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2427 handling is now the same as that of other special attributes like __name__).
2428
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002429- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2430 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002819 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002820
2821 This is controlled by the configure argument ``--with-universal-archs``:
2822
2823 - ``--with-universal-archs=all``: install 4-way universal
2824
2825 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2826
2827 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2828
2829 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Issue #1631171: Re-implement the 'warnings' module in C (the
2882 original Python code has been kept as backup). This will allow for
2883 using the 'warning's machinery in such places as the parser where
2884 use of pure Python code is not possible. Both the ``showarning()``
2885 and ``formatwarning()`` gain an optional 'line' argument which is
2886 not called by default for backwards-compatibility reasons. Setting
2887 ``warnings.showwarning()`` to an implementation that lacks support
2888 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Issue #2550: The approach used by client/server code for obtaining
2952 ports to listen on in network-oriented tests has been refined in an
2953 effort to facilitate running multiple instances of the entire
2954 regression test suite in parallel without issue.
2955 test_support.bind_port() has been fixed such that it will always
2956 return a unique port -- which wasn't always the case with the
2957 previous implementation, especially if socket options had been set
2958 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2959 new implementation of bind_port() will actually raise an exception
2960 if it is passed an AF_INET/SOCK_STREAM socket with either the
2961 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2962 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2963 the socket it's been passed. This currently only applies to
2964 Windows. This option prevents any other sockets from binding to the
2965 host/port we've bound to, thus removing the possibility of the
2966 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2967 when a second SOCK_STREAM socket binds and accepts to a host/port
2968 that's already been bound by another socket. The optional preferred
2969 port parameter to bind_port() has been removed. Under no
2970 circumstances should tests be hard coding ports!
2971
2972 test_support.find_unused_port() has also been introduced, which will
2973 pass a temporary socket object to bind_port() in order to obtain an
2974 unused port. The temporary socket object is then closed and
2975 deleted, and the port is returned. This method should only be used
2976 for obtaining an unused port in order to pass to an external program
2977 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2978 a parameter to a server-oriented class that doesn't give you direct
2979 access to the underlying socket used.
2980
2981 Finally, test_support.HOST has been introduced, which should be used
2982 for the host argument of any relevant socket calls (i.e. bind and
2983 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002984
2985 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002986 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3257Core and builtins
3258-----------------
3259
Fred Drakea8ee94b2008-03-01 02:45:07 +00003260- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003261 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003262
Georg Brandlad61bc82008-02-23 15:11:18 +00003263- Issue #2067: file.__exit__() now calls subclasses' close() method.
3264
3265- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003266
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003267- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl21896072010-08-01 22:31:28 +00003268 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00003269
Eric Smitha73fbe72008-02-23 03:09:44 +00003270- Added the future_builtins module, which contains hex() and oct().
3271 These are the PEP 3127 version of these functions, designed to be
3272 compatible with the hex() and oct() builtins from Python 3.0. They
3273 differ slightly in their output formats from the existing, unchanged
3274 Python 2.6 builtins. The expected usage of the future_builtins
3275 module is:
3276 from future_builtins import hex, oct
3277
Eric Smith7ef40bf2008-02-20 23:34:22 +00003278- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3279 exponents for exponents with absolute value < 100. Follows C99
3280 standard. This is a change on Windows, which would use 3 digits.
3281 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3282 so that any alterations it does to the resulting string will be
3283 available in stringlib/formatter.h (for float.__format__).
3284
Eric Smith5a3c1352008-02-19 13:21:56 +00003285- Implemented PEP 3101, Advanced String Formatting. This adds a new
3286 builtin format(); a format() method for str and unicode; a
3287 __format__() method to object, str, unicode, int, long, float, and
3288 datetime; the class string.Formatter; and the C API
3289 PyObject_Format().
3290
Georg Brandl3ee81df2008-05-17 18:14:43 +00003291- Fixed several potential crashes, all caused by specially crafted
3292 __del__ methods exploiting objects in temporarily inconsistent
3293 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003294
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003295- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003296 prevent a possible crash: an Abstract Base Class would try to access
3297 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Fixed repr() and str() of complex numbers with infinity or nan as
3300 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003301
Georg Brandl3ee81df2008-05-17 18:14:43 +00003302- Clear all free lists during a gc.collect() of the highest generation
3303 in order to allow pymalloc to free more arenas. Python may give back
3304 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003305
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306- Issue #2045: Fix an infinite recursion triggered when printing a
3307 subclass of collections.defaultdict, if its default_factory is set
3308 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003309
Christian Heimesf75dbef2008-02-08 00:11:31 +00003310- Fixed a minor memory leak in dictobject.c. The content of the free
3311 list was not freed on interpreter shutdown.
3312
Georg Brandl5a7eca12010-03-21 19:29:04 +00003313- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3317 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003318 to compact the internal free lists of pre-allocted ints and floats.
3319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3321 calls. Python expected the return type int but the fork familie
3322 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3325 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003326
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3328 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003329
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3331 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3334 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003335
Georg Brandl3ee81df2008-05-17 18:14:43 +00003336- Patch #1473257: generator objects gain a gi_code attribute. This is
3337 the same object as the func_code attribute of the function that
3338 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003339
Georg Brandl3ee81df2008-05-17 18:14:43 +00003340- Issue #1920: "while 0" statements were completely removed by the
3341 compiler, even in the presence of an "else" clause, which is
3342 supposed to be run when the condition is false. Now the compiler
3343 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003344
Guido van Rossumeead05f2008-01-24 18:21:02 +00003345- A few crashers fixed: weakref_in_del.py (issue #1377858);
3346 loosing_dict_ref.py (issue #1303614, test67.py);
3347 borrowed_ref_[34].py (not in tracker).
3348
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003349- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003350 suppressed while an extension is loaded by calling SetErrorMode in
3351 dynload_win.c. The error is still reported properly.
3352
Georg Brandl3ee81df2008-05-17 18:14:43 +00003353- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003354 several extension methods and modules do not work without unicode
3355 support.
3356
Georg Brandl26543b12008-01-21 18:36:51 +00003357- Issue #1882: when compiling code from a string, encoding cookies in the
3358 second line of code were not always recognized correctly.
3359
Georg Brandl14404b62008-01-19 19:27:05 +00003360- Issue #1679: "0x" was taken as a valid integer literal.
3361
Georg Brandl6caad7d2008-01-26 14:19:22 +00003362- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003363 added.
3364
Christian Heimesc94e2b52008-01-14 04:13:37 +00003365- sys.float_info / PyFloat_GetInfo: The floating point information
3366 object was converted from a dict to a specialized structseq object.
3367
Georg Brandl3ee81df2008-05-17 18:14:43 +00003368- Patch #1816: Added sys.flags structseq. It exposes the status of
3369 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003370
Georg Brandl3ee81df2008-05-17 18:14:43 +00003371- Objects/structseq.c: Implemented new structseq representation. The
3372 patch makes structseqs (e.g. the return value of os.stat) more
3373 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003374
Georg Brandl3ee81df2008-05-17 18:14:43 +00003375- Patch #1700288: added a type attribute cache that caches method
3376 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003377
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003378- Bug #1776: __import__() no longer accepts filenames on any platform.
3379 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003380
Georg Brandlaed6c662008-01-07 17:25:53 +00003381- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3382
Georg Brandl3ee81df2008-05-17 18:14:43 +00003383- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3384 envvar and sys.dont_write_bytecode attribute. All these can be set
3385 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Improve some exception messages when Windows fails to load an
3388 extension module. Now we get for example '%1 is not a valid Win32
3389 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003390
Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3394 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003395
Christian Heimes0a8143f2007-12-18 23:22:54 +00003396- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003397 and INF. float("nan"), float("inf") and float("-inf") now work on
3398 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003399
Georg Brandl3ee81df2008-05-17 18:14:43 +00003400- Compiler now generates simpler and faster code for dictionary
3401 literals. The oparg for BUILD_MAP now indicates an estimated
3402 dictionary size. There is a new opcode, STORE_MAP, for adding
3403 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003404
Georg Brandl3ee81df2008-05-17 18:14:43 +00003405- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00003406
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Issue #1620: New property decorator syntax was modifying the
3408 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003409
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- Issue #1538: Avoid copying string in split/rsplit if the split char
3411 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003412
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003413- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003414 SystemError.
3415
Nick Coghlanef01d822007-12-03 12:55:17 +00003416- PEP 366: Allow explicit relative imports when executing modules
3417 inside packages with the -m switch via a new module level
3418 __package__ attribute.
3419
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420- Issue #1402: Fix a crash on exit, when another thread is still
3421 running, and if the deallocation of its frames somehow calls the
3422 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003423

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003427 attribute of an empty cell object.
3428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Issue #1460: The utf-7 incremental decoder did not accept truncated
3430 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003431
Georg Brandl3ee81df2008-05-17 18:14:43 +00003432- Patch #1739468: Directories and zipfiles containing a __main__.py
3433 file can now be directly executed by passing their name to the
3434 interpreter. The directory/zipfile is automatically inserted as the
3435 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003436
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437- Issue #1265: Fix a problem with sys.settrace, if the tracing
3438 function uses a generator expression when at the same time the
3439 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003440
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003441- sets and frozensets now have an isdisjoint() method.
3442
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003443- optimize the performance of builtin.sum().
3444
Neal Norwitz44f326e2007-10-05 05:29:17 +00003445- Fix warnings found by the new version of the Coverity checker.
3446
Georg Brandl5a7eca12010-03-21 19:29:04 +00003447- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3449 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Issue #1686386: Tuple's tp_repr did not take into account the
3452 possibility of having a self-referential tuple, which is possible
3453 from C code. Nor did object's tp_str consider that a type's tp_str
3454 could do something that could lead to an inifinite recursion.
3455 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3456 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Issue #1164: It was possible to trigger deadlock when using the
3459 'print' statement to write to a file since the GIL was not released
3460 as needed. Now PyObject_Print() does the right thing along with
3461 various tp_print implementations of the built-in types and those in
3462 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003463
Georg Brandl3ee81df2008-05-17 18:14:43 +00003464- Issue #1147: Exceptions were directly allowing string exceptions in
3465 their throw() method even though string exceptions no longer
3466 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003467
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468- Issue #1096: Prevent a segfault from getting the repr of a very
3469 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003470
Brett Cannon1e534b52007-09-07 04:18:30 +00003471- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003472 PyObject_Call() never calling back out to Python code to trigger
3473 recursion depth updates/checks. Required the creation of a static
3474 RuntimeError instance in case normalizing an exception put the
3475 recursion check value past its limit. Fixes crashers
3476 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003477
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- Patch #1031213: Decode source line in SyntaxErrors back to its

3482 with %G.
3483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Prevent expandtabs() on string and unicode objects from causing a
3485 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- Issue #1733488: Fix compilation of bufferobject.c on AIX.
Martin v. Löwisda587ab2007-06-08 17:29:20 +00003488

Neal Norwitz0ac60192007-05-27 04:08:54 +00003491- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003492 __*__ attributes. (Some already existed, e.g., __doc__ and

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003495- Add -3 option to the interpreter to warn about features that are
3496 deprecated and will be changed/removed in Python 3.0.
3497
Georg Brandl2134e752007-05-21 20:34:16 +00003498- Patch #1686487: you can now pass any mapping after '**' in function
3499 calls.
3500
Collin Winter62903052007-05-18 23:11:24 +00003501- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003502 "except E as target:". This is to provide forwards compatibility
3503 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003504
Brett Cannon229cee22007-05-05 01:34:02 +00003505- Deprecate BaseException.message as per PEP 352.
3506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003508 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003509
Vinay Sajip8549ce32007-05-06 17:53:37 +00003510- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003511 setting a plain string, ie don't expand to single letter identifiers.
3512
Raymond Hettinger13936692007-04-11 18:40:58 +00003513- Request #1191699: Slices can now be pickled.
3514
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003515- Request #1193128: str.translate() now allows a None argument for
3516 translations that only remove characters without re-mapping the
3517 remaining characters.
3518
Georg Brandl5cb76c12007-03-21 09:00:39 +00003519- Patch #1682205: a TypeError while unpacking an iterable is no longer
3520 masked by a generic one with the message "unpack non-sequence".
3521

3523
Guido van Rossum143b5642007-03-23 04:58:42 +00003524- Bug #1683368: The object.__init__() and object.__new__() methods are
3525 now stricter in rejecting excess arguments. The only time when
3526 either allows excess arguments is when it is not overridden and the
3527 other one is. For backwards compatibility, when both are
3528 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003529 warning later). Also, type.__init__() insists on the same signature
3530 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3533 object to complex using its __complex__() method before falling back
3534 to the __float__() method. Therefore, the functions in the cmath
3535 module now can operate on objects that define a __complex__()
3536 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003537

3539 __slots__. The old and the new class are still required to have the
3540 same slot names.

3553
Georg Brandl7b9c5552007-03-12 14:30:05 +00003554- Bug #1678647: write a newline after printing an exception in any
3555 case, even when converting the value to a string failed.
3556
Georg Brandl871f1bc2007-03-12 13:17:36 +00003557- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003558 its argument, if it exists. If not, it will work like before. This
3559 allows customizing the output of dir() in the presence of a
3560 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003561
Collin Winter276887b2007-03-12 16:11:39 +00003562- Patch #922167: Python no longer segfaults when faced with infinitely
3563 self-recursive reload() calls (as reported by bug #742342).
3564
Georg Brandl3ee81df2008-05-17 18:14:43 +00003565- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003568- Patch #1491866: change the complex() constructor to allow
3569 parthensized forms. This means complex(repr(x)) now works instead of
3570 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003571
Georg Brandlaa2321b2007-03-07 00:40:28 +00003572- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003573 makes the filenames the warning module prints much more sensible
3574 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003575
Georg Brandl49aafc92007-03-07 00:34:46 +00003576- Variant of patch #697613: don't exit the interpreter on a SystemExit
3577 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003578 variable is given, but break into the interactive interpreter just
3579 like on other exceptions or normal program exit.

3585 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003586
Georg Brandl0fca97a2007-03-05 22:28:08 +00003587- Patch #1674228: when assigning a slice (old-style), check for the
3588 sq_ass_slice instead of the sq_slice slot.
3589
Georg Brandl3ee81df2008-05-17 18:14:43 +00003590- When printing an unraisable error, don't print exceptions. before
3591 the name. This duplicates the behavior whening normally printing
3592 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003593
Georg Brandl3ee81df2008-05-17 18:14:43 +00003594- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003600- Bug #1377858: Fix the segfaulting of the interpreter when an object
3601 created a weakref on itself during a __del__ call for new-style
3602 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00003603
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00003604- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00003642- Bug #1545497: when given an explicit base, int() did ignore NULs
3643 embedded in the string to convert.
3644
Georg Brandl846f73a2006-10-08 07:11:54 +00003645- Bug #1569998: break inside a try statement (outside a loop) is now
3646 recognized and rejected.
3647

Georg Brandl4e933132006-09-06 20:05:58 +00003675- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003693 generator expressions (x for x, in ... ) works again. Fixing this
3694 problem required changing the .pyc magic number. This means that
3695 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003734- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004125 AttributeError instead of an IOError when the server's response
4126 didn't contain a valid HTTP status line.

4217 TestCase and TestSuite subclasses (not instances) are no longer
4218 accepted in TestSuite.addTest(). This should cause no

4500 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004501
Georg Brandl3ee81df2008-05-17 18:14:43 +00004502- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4503 with RFC 3207 and forgets any knowledge obtained from the server not
4504 obtained from the TLS negotiation itself. Patch contributed by Bill
4505 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004506
Georg Brandl3ee81df2008-05-17 18:14:43 +00004507- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004508 that the SMTP.starttls() caller no longer needs to call ehlo()
4509 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510 does not claim to support starttls. Adds the
4511 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4592 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4593 silently miscode subclasses of those types. Now, it raises a
4594 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004595

Georg Brandl3ee81df2008-05-17 18:14:43 +00004610 time so that opening a database previously created with the DB_DUP
4611 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4612 opens. Specifically: dictionary assignment to a DB object will
4613 replace all values for a given key when the database allows
4614 duplicate values. DB users should use DB.put(k, v) when they want
4615 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004616

4622 characters with ASCII value less than 32. Also, it correctly quotes
4623 dots only if they occur on a single line, as opposed to the previous
4624 behavior of quoting dots if they are the second character of any
4625 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004626

Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4971 of w# format code incorrectly truncated the length to an int, even
4972 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4973 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004974
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005003- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5004 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005005
Georg Brandl3ee81df2008-05-17 18:14:43 +00005006- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5014 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5015 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5016 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005017

Georg Brandl3ee81df2008-05-17 18:14:43 +00005031- Removed the macfs module. It had been deprecated since Python 2.5.
5032 This lead to the deprecation of macostools.touched() as it relied
5033 solely on macfs and was a no-op under OS X.
