1023 do an explicit seek to the end of file (so that e.g. tell() returns the
1024 file size rather than 0). This is consistent with the behaviour of the
1025 traditional 2.x file object.

1058
1059- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1060 302 conformant loader) will now work correctly in most cases (they

1221What's New in Python 2.6.1
1222==========================
1223
1224*Release date: 04-Dec-2008*
1225
1226Core and Builtins
1227-----------------
1228
1229- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1230 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1231 instead of throwing a MemoryError.
1232
1233- Issue #4367: Python would segfault during compiling when the unicodedata
1234 module couldn't be imported and \N escapes were present.
1235
1236- Issue #4348: Some bytearray methods returned that didn't cause any change to
1237 the bytearray, returned the same bytearray instead of a copy.
1238
1239- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1240
1241- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1242
1243- Issue #4048: The parser module now correctly validates relative imports.
1244
1245- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1246 exec statement.
1247
1248- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1249 method does not return iterators for the 4th and 5th items.
1250
1251- Issue #4209: Enabling unicode_literals and the print_function in the same
1252 __future__ import didn't work.
1253
1254- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1255 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1256 really executed because I cannot move to such directory on win2k)
1257
1258- Issue #4069: When set.remove(element) is used with a set element, the element
1259 is temporarily replaced with an equivalent frozenset. But the eventual
1260 KeyError would always report the empty frozenset([]) as the missing key. Now
1261 it correctly refers to the initial element.
1262
1263- Fixed C99 style comments in several files. Python is now C89 compatible
1264 again.
1265

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001411- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1412
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001413- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1414 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1415 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1416 ``printf`` function, whereas PyString_FromFormat has an independent
1417 implementation and uses "%zd" on all platforms for size_t values.
1418 This makes a difference on win64, where ``printf`` needs "%Id" to display
1419 64bit values.

1425 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001436 was correctly parsed but parsing of subsequent arguments failed.
1437
Vinay Sajip35e3b032008-09-01 14:33:59 +00001438- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001439 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1440 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1441 when given a tuple of classes as second argument, were looking up
1442 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1443 type object.

1590 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1591 to their tp_flags field if they care. This is a backwards
1592 compatibility feature; in 3.0, all types will use the cache by
1593 default.
1594
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001595- Keyword arguments can now follow starred arguments. (``f(a, *args,
1596 keyword=23)`` is now valid syntax.)
1597
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001598- ctypes function pointers that are COM methods have a boolean True
1599 value again.
1600
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001601- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1602 by denying s# to parse objects that have a releasebuffer procedure,
1603 and introducing s*.
1604
Georg Brandl1e13ea92008-08-11 09:07:59 +00001605- Issue #3537: Fix an assertion failure when an empty but presized dict
1606 object was stored in the freelist.
1607
Mark Dickinsonb6467572008-08-04 21:30:09 +00001608- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1609 ValueError consistently across platforms.
1610
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001611- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1612 (64bit Unix, for example), unichr() would truncate its argument and return
1613 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1614
Neal Norwitze7d8be82008-07-31 17:17:14 +00001615- Apply security patches from Apple.
1616
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001617- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1618 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1619
Antoine Pitrou92f82162008-07-25 22:22:08 +00001620- Issue #1819: function calls with several named parameters are now on
1621 average 35% faster (as measured by pybench).
1622
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001623- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1624 the python debugger steps into a class statement: the free variables (local
1625 variables defined in an outer scope) would be deleted from the outer scope.
1626
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001627- Issue #2620: Overflow checking when allocating or reallocating memory
1628 was not always being done properly in some python types and extension
1629 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1630 all been updated to perform better checks and places in the code that
1631 would previously leak memory on the error path when such an allocation
1632 failed have been fixed.

1638
Benjamin Petersone977ad42008-08-20 01:42:01 +00001639- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1640 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1641
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001642- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1643 version reported by these tools does not necessarily follow the python
1644 version numbering scheme, so the module is less strict when parsing it.
1645
Nick Coghlanf70385a2008-08-18 12:42:46 +00001646- Issue #2235: Added Py3k warnings for types which will become unhashable
1647 under the stricter __hash__ inheritance rules in 3.0. Several types
1648 which did not meet the rules for hash invariants and were already
1649 unhashable in 3.0 have now been explicitly flagged as unhashable in
1650 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1651 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1652
Brett Cannon88f801d2008-08-18 00:46:22 +00001653- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1654 imported into the module but exposed as part of the module's API.
1655
Brett Cannon7b96f072008-08-18 00:41:11 +00001656- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1657

1661
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001662- Issue #3575: Incremental decoder's decode function now takes bytearray
1663 by using 's*' instead of 't#'.
1664
Jesus Cea585ad8a2009-07-02 15:37:21 +00001665- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001666 fails unicode conversion on 2nd parameter. (windows only)
1667
Facundo Batista94f243a2008-08-17 03:38:39 +00001668- Issue 2464. urllib2 now supports a malformation in the URL received
1669 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00001671- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001672 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001673
Facundo Batistaeb90b782008-08-16 14:44:07 +00001674- Issue #2776: fixed small issue when handling an URL with double slash
1675 after a 302 response in the case of not going through a proxy.
1676
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001677- Issue #2676: in the email package, content-type parsing was hanging on
1678 pathological input because of quadratic or exponential behaviour of a
1679 regular expression.
1680
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001681- Issue #3476: binary buffered reading through the new "io" library is now
1682 thread-safe.
1683
Brett Cannonbf3157b2008-08-14 05:00:03 +00001684- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1685 since mimetools itself is deprecated. Because modules are cached, all
1686 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1687
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001688- Issue #3134: shutil referenced undefined WindowsError symbol.
1689
Robert Schuppenies14646332008-08-10 11:01:53 +00001690- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1691 menu entries were not deleted.
1692
Brett Cannon83e81842008-08-09 23:30:55 +00001693- Copied the implementation of reduce() to _functools.reduce() to have a
1694 version that did not raise a DeprecationWarning under -3.
1695
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001696- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1697 a MemoryError rather than silently stop the iteration.
1698
Guido van Rossum59ce9012008-08-09 14:55:34 +00001699- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1700 to _sre.compile() will now be rejected. This should not affect anybody
1701 since the re.compile() function never generates invalid re-bytecode.
1702
Skip Montanaroa032bf42008-08-08 22:52:51 +00001703- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1704 upon first access it can be automatically initialized from the csv file if
1705 it wasn't initialized during instantiation.
1706
Brett Cannon3aa2a492008-08-06 22:28:09 +00001707- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1708 the reload() built-in has been removed.
1709
Brett Cannon7e30b672008-08-04 21:52:25 +00001710- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001711 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1719 raised an AttributeError.
1720
Benjamin Peterson01a24322008-07-28 23:35:27 +00001721- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001722 asking for a specific length. This problem only affected files opened
1723 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001724
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001725- Issue #3449: Update decimal module to use most recent specification
1726 (v. 1.68) and tests (v. 2.58) from IBM.
1727

1743- Issue #3389: Allow resolving dotted names for handlers in logging
1744 configuration files.
1745
1746- Deprecate the sunaudio module for removal in Python 3.0.
1747
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001748- Issue #3394: zipfile.writestr sets external attributes when passed a
1749 file name rather than a ZipInfo instance, so files are extracted with
1750 mode 0600 rather than 000 under Unix.
1751
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001752- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1753 argument in python 2.5, this broke code that subclassed Popen to include its
1754 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1762-------------
1763
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001764- Issue #2235: the C API function PyObject_HashNotImplemented and its
1765 interaction with the tp_hash slot (added in 2.6b2) are now documented
1766
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001767- Issue #643841: The language reference now provides more detailed
1768 coverage of the lookup process for special methods. The disclaimers
1769 regarding lack of coverage of new-style classes have also been
1770 removed, since the coverage is now fairly reasonable.

1775
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001776*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001778Core and Builtins
1779-----------------
1780
Georg Brandl3e483f62008-07-16 22:57:41 +00001781- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1782 its methods now allow for items objects that can be converted to
1783 an integer using operator.index().
1784
Mark Dickinson64b7e502008-07-16 09:40:03 +00001785- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1786 produced a ValueError instead of giving the correct float.
1787
Eric Smitha5fa5a22008-07-16 00:11:49 +00001788- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1789 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1790
Mark Dickinson7103aa42008-07-15 19:08:33 +00001791- Issue #3008: the float type has a new instance method 'float.hex'
1792 and a new class method 'float.fromhex' to convert floating-point
1793 numbers to and from hexadecimal strings, respectively.
1794
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001795- Issue #2235: __hash__ is once again inherited by default. To allow
1796 collections.Hashable to remain meaningful in the presence of the
1797 default hash implementation (object.__hash__), it is now possible
1798 to explicit block inheritance of hash by setting __hash__=None at
1799 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1800 level.
1801
Nick Coghlanb028f502008-07-13 14:52:36 +00001802- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1803 the parent module cannot be found while performing an absolute import.
1804 This means that an incorrectly defined __package__ attribute will
1805 now only prevent relative imports in that module rather than causing
1806 all imports from that module to fail.
1807
Nick Coghlan14ff9942008-07-08 14:21:42 +00001808- Issue #2517: Allow unicode messages in Exceptions again by correctly
1809 bypassing the instance dictionary when looking up __unicode__ on
1810 new-style classes.
1811
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001812- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1813 set to a custom object whose write() method happens to install
1814 another file in sys.stdout.
1815
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001816- Issue #3088: Corrected a race condition in classes derived from
1817 threading.local: the first member set by a thread could be saved in
1818 another thread's dictionary.
1819
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001820- Issue #3004: Minor change to slice.indices(): the start and stop
1821 arguments are now treated identically, making the behaviour easier
1822 to describe and understand. For example, slice(None, -10,
1823 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1824 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1825 10, -1).
1826
Georg Brandl278fc502008-07-19 12:46:12 +00001827- Issue #3219: Calling a function with repeated keyword arguments,
1828 f(a=2, a=23), would not cause a syntax error. This was a regression
1829 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001830
Georg Brandl278fc502008-07-19 12:46:12 +00001831- Issue #2862: Make int and float freelist management consistent with
1832 other freelists. Changes their CompactFreeList apis into
1833 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001834

1836-------
1837
Thomas Heller57adf222008-08-14 19:10:48 +00001838- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1839 api functions without holding the GIL, which could lead to a fatal
1840 error when they failed.
1841
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001842- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001850- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1851 ForkingPickler.register() to resolve conflict with ctypes.
1852
Vinay Sajip51e65192008-07-18 09:01:10 +00001853- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001854
Thomas Heller880f5292008-07-15 19:39:38 +00001855- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1856 a valid dlerror() message.
1857
Thomas Heller2bad6572008-07-15 17:19:50 +00001858- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1859 incomplete structure was created.
1860
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001861- Issue #3339: dummy_thread.acquire() should not return None.
1862
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001863- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1864
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001865- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001866
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001867- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1868 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001869 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001870 content-length. The problem had been corrected in the 2.4 branch, but never
1871 merged into trunk.
1872
Georg Brandle78fbcc2008-07-05 10:13:36 +00001873- Issue #2663: add filtering capability to shutil.copytree().
1874

1876
1877- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1878

Georg Brandl5cc774e2008-06-11 20:28:06 +00002279 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002280
2281 This is controlled by the configure argument ``--with-universal-archs``:
2282
2283 - ``--with-universal-archs=all``: install 4-way universal
2284
2285 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2286
2287 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2288
2289 This option should be used in combination with ``--enable-universalsdk=``.
2290
2291 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Issue #1631171: Re-implement the 'warnings' module in C (the
2342 original Python code has been kept as backup). This will allow for
2343 using the 'warning's machinery in such places as the parser where
2344 use of pure Python code is not possible. Both the ``showarning()``
2345 and ``formatwarning()`` gain an optional 'line' argument which is
2346 not called by default for backwards-compatibility reasons. Setting
2347 ``warnings.showwarning()`` to an implementation that lacks support
2348 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002411- Issue #2550: The approach used by client/server code for obtaining
2412 ports to listen on in network-oriented tests has been refined in an
2413 effort to facilitate running multiple instances of the entire
2414 regression test suite in parallel without issue.
2415 test_support.bind_port() has been fixed such that it will always
2416 return a unique port -- which wasn't always the case with the
2417 previous implementation, especially if socket options had been set
2418 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2419 new implementation of bind_port() will actually raise an exception
2420 if it is passed an AF_INET/SOCK_STREAM socket with either the
2421 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2422 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2423 the socket it's been passed. This currently only applies to
2424 Windows. This option prevents any other sockets from binding to the
2425 host/port we've bound to, thus removing the possibility of the
2426 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2427 when a second SOCK_STREAM socket binds and accepts to a host/port
2428 that's already been bound by another socket. The optional preferred
2429 port parameter to bind_port() has been removed. Under no
2430 circumstances should tests be hard coding ports!
2431
2432 test_support.find_unused_port() has also been introduced, which will
2433 pass a temporary socket object to bind_port() in order to obtain an
2434 unused port. The temporary socket object is then closed and
2435 deleted, and the port is returned. This method should only be used
2436 for obtaining an unused port in order to pass to an external program
2437 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2438 a parameter to a server-oriented class that doesn't give you direct
2439 access to the underlying socket used.
2440
2441 Finally, test_support.HOST has been introduced, which should be used

2717Core and builtins
2718-----------------
2719
Fred Drakea8ee94b2008-03-01 02:45:07 +00002720- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002721 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002722
Georg Brandlad61bc82008-02-23 15:11:18 +00002723- Issue #2067: file.__exit__() now calls subclasses' close() method.
2724
2725- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002726
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002727- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002728 issue 215555 for a discussion.
2729
Eric Smitha73fbe72008-02-23 03:09:44 +00002730- Added the future_builtins module, which contains hex() and oct().
2731 These are the PEP 3127 version of these functions, designed to be
2732 compatible with the hex() and oct() builtins from Python 3.0. They
2733 differ slightly in their output formats from the existing, unchanged
2734 Python 2.6 builtins. The expected usage of the future_builtins
2735 module is:
2736 from future_builtins import hex, oct
2737
Eric Smith7ef40bf2008-02-20 23:34:22 +00002738- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2739 exponents for exponents with absolute value < 100. Follows C99
2740 standard. This is a change on Windows, which would use 3 digits.
2741 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2742 so that any alterations it does to the resulting string will be
2743 available in stringlib/formatter.h (for float.__format__).
2744
Eric Smith5a3c1352008-02-19 13:21:56 +00002745- Implemented PEP 3101, Advanced String Formatting. This adds a new
2746 builtin format(); a format() method for str and unicode; a
2747 __format__() method to object, str, unicode, int, long, float, and
2748 datetime; the class string.Formatter; and the C API
2749 PyObject_Format().
2750
Georg Brandl3ee81df2008-05-17 18:14:43 +00002751- Fixed several potential crashes, all caused by specially crafted
2752 __del__ methods exploiting objects in temporarily inconsistent
2753 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002754
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002755- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756 prevent a possible crash: an Abstract Base Class would try to access
2757 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002758
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759- Fixed repr() and str() of complex numbers with infinity or nan as
2760 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- Clear all free lists during a gc.collect() of the highest generation
2763 in order to allow pymalloc to free more arenas. Python may give back
2764 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002765
Georg Brandl3ee81df2008-05-17 18:14:43 +00002766- Issue #2045: Fix an infinite recursion triggered when printing a
2767 subclass of collections.defaultdict, if its default_factory is set
2768 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002769
Christian Heimesf75dbef2008-02-08 00:11:31 +00002770- Fixed a minor memory leak in dictobject.c. The content of the free
2771 list was not freed on interpreter shutdown.
2772
Georg Brandl3ee81df2008-05-17 18:14:43 +00002773- Limit free list of method and builtin function objects to 256
2774 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002775
Georg Brandl3ee81df2008-05-17 18:14:43 +00002776- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2777 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002778 to compact the internal free lists of pre-allocted ints and floats.
2779
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2781 calls. Python expected the return type int but the fork familie
2782 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2785 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2788 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002789
Georg Brandl3ee81df2008-05-17 18:14:43 +00002790- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2791 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002792
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2794 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Patch #1473257: generator objects gain a gi_code attribute. This is
2797 the same object as the func_code attribute of the function that
2798 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002799
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800- Issue #1920: "while 0" statements were completely removed by the
2801 compiler, even in the presence of an "else" clause, which is
2802 supposed to be run when the condition is false. Now the compiler
2803 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002804
Guido van Rossumeead05f2008-01-24 18:21:02 +00002805- A few crashers fixed: weakref_in_del.py (issue #1377858);
2806 loosing_dict_ref.py (issue #1303614, test67.py);
2807 borrowed_ref_[34].py (not in tracker).
2808
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002809- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002810 suppressed while an extension is loaded by calling SetErrorMode in
2811 dynload_win.c. The error is still reported properly.
2812
Georg Brandl3ee81df2008-05-17 18:14:43 +00002813- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002814 several extension methods and modules do not work without unicode
2815 support.
2816
Georg Brandl26543b12008-01-21 18:36:51 +00002817- Issue #1882: when compiling code from a string, encoding cookies in the
2818 second line of code were not always recognized correctly.
2819
Georg Brandl14404b62008-01-19 19:27:05 +00002820- Issue #1679: "0x" was taken as a valid integer literal.
2821
Georg Brandl6caad7d2008-01-26 14:19:22 +00002822- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002823 added.
2824
Christian Heimesc94e2b52008-01-14 04:13:37 +00002825- sys.float_info / PyFloat_GetInfo: The floating point information
2826 object was converted from a dict to a specialized structseq object.
2827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Patch #1816: Added sys.flags structseq. It exposes the status of
2829 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Objects/structseq.c: Implemented new structseq representation. The
2832 patch makes structseqs (e.g. the return value of os.stat) more
2833 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835- Patch #1700288: added a type attribute cache that caches method
2836 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002837
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002838- Bug #1776: __import__() no longer accepts filenames on any platform.
2839 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002840
Georg Brandlaed6c662008-01-07 17:25:53 +00002841- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2842
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2844 envvar and sys.dont_write_bytecode attribute. All these can be set
2845 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002846
Georg Brandl3ee81df2008-05-17 18:14:43 +00002847- Improve some exception messages when Windows fails to load an
2848 extension module. Now we get for example '%1 is not a valid Win32
2849 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2854 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002855
Christian Heimes0a8143f2007-12-18 23:22:54 +00002856- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857 and INF. float("nan"), float("inf") and float("-inf") now work on
2858 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002859
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860- Compiler now generates simpler and faster code for dictionary
2861 literals. The oparg for BUILD_MAP now indicates an estimated
2862 dictionary size. There is a new opcode, STORE_MAP, for adding
2863 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Issue #1620: New property decorator syntax was modifying the
2868 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002869
Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Issue #1538: Avoid copying string in split/rsplit if the split char
2871 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002872
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002873- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002874 SystemError.
2875
Nick Coghlanef01d822007-12-03 12:55:17 +00002876- PEP 366: Allow explicit relative imports when executing modules
2877 inside packages with the -m switch via a new module level
2878 __package__ attribute.
2879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Issue #1402: Fix a crash on exit, when another thread is still
2881 running, and if the deallocation of its frames somehow calls the
2882 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002883

2893 file can now be directly executed by passing their name to the
2894 interpreter. The directory/zipfile is automatically inserted as the
2895 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002896
Georg Brandl3ee81df2008-05-17 18:14:43 +00002897- Issue #1265: Fix a problem with sys.settrace, if the tracing
2898 function uses a generator expression when at the same time the
2899 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002900
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002901- sets and frozensets now have an isdisjoint() method.
2902
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002903- optimize the performance of builtin.sum().
2904
Neal Norwitz44f326e2007-10-05 05:29:17 +00002905- Fix warnings found by the new version of the Coverity checker.
2906
Georg Brandl3ee81df2008-05-17 18:14:43 +00002907- The enumerate() builtin function is no longer bounded to sequences
2908 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2909 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Issue #1686386: Tuple's tp_repr did not take into account the
2912 possibility of having a self-referential tuple, which is possible
2913 from C code. Nor did object's tp_str consider that a type's tp_str
2914 could do something that could lead to an inifinite recursion.
2915 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2916 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Issue #1164: It was possible to trigger deadlock when using the
2919 'print' statement to write to a file since the GIL was not released
2920 as needed. Now PyObject_Print() does the right thing along with
2921 various tp_print implementations of the built-in types and those in
2922 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002923
Georg Brandl3ee81df2008-05-17 18:14:43 +00002924- Issue #1147: Exceptions were directly allowing string exceptions in
2925 their throw() method even though string exceptions no longer
2926 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002927
Georg Brandl3ee81df2008-05-17 18:14:43 +00002928- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002931- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002932 PyObject_Call() never calling back out to Python code to trigger
2933 recursion depth updates/checks. Required the creation of a static
2934 RuntimeError instance in case normalizing an exception put the
2935 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002951- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002952 __*__ attributes. (Some already existed, e.g., __doc__ and
2953 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002954
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002955- Add -3 option to the interpreter to warn about features that are

2959 calls.
2960
Collin Winter62903052007-05-18 23:11:24 +00002961- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002962 "except E as target:". This is to provide forwards compatibility
2963 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002964
Brett Cannon229cee22007-05-05 01:34:02 +00002965- Deprecate BaseException.message as per PEP 352.
2966
Georg Brandl3ee81df2008-05-17 18:14:43 +00002967- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002968 inherited from a builtin base.
2969
Vinay Sajip8549ce32007-05-06 17:53:37 +00002970- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002971 setting a plain string, ie don't expand to single letter identifiers.
2972
Raymond Hettinger13936692007-04-11 18:40:58 +00002973- Request #1191699: Slices can now be pickled.
2974
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002975- Request #1193128: str.translate() now allows a None argument for
2976 translations that only remove characters without re-mapping the
2977 remaining characters.
2978
Georg Brandl5cb76c12007-03-21 09:00:39 +00002979- Patch #1682205: a TypeError while unpacking an iterable is no longer
2980 masked by a generic one with the message "unpack non-sequence".
2981

2983
Guido van Rossum143b5642007-03-23 04:58:42 +00002984- Bug #1683368: The object.__init__() and object.__new__() methods are
2985 now stricter in rejecting excess arguments. The only time when
2986 either allows excess arguments is when it is not overridden and the
2987 other one is. For backwards compatibility, when both are
2988 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002989 warning later). Also, type.__init__() insists on the same signature
2990 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002991
Georg Brandl3ee81df2008-05-17 18:14:43 +00002992- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2993 object to complex using its __complex__() method before falling back
2994 to the __float__() method. Therefore, the functions in the cmath
2995 module now can operate on objects that define a __complex__()
2996 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Patch #1623563: allow __class__ assignment for classes with
2999 __slots__. The old and the new class are still required to have the
3000 same slot names.

3007 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003008

3013
Georg Brandl7b9c5552007-03-12 14:30:05 +00003014- Bug #1678647: write a newline after printing an exception in any
3015 case, even when converting the value to a string failed.
3016
Georg Brandl871f1bc2007-03-12 13:17:36 +00003017- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018 its argument, if it exists. If not, it will work like before. This
3019 allows customizing the output of dir() in the presence of a
3020 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003021
Collin Winter276887b2007-03-12 16:11:39 +00003022- Patch #922167: Python no longer segfaults when faced with infinitely
3023 self-recursive reload() calls (as reported by bug #742342).
3024
Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Patch #1675981: remove unreachable code from ``type.__new__()``

3029 parthensized forms. This means complex(repr(x)) now works instead of
3030 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003031
Georg Brandlaa2321b2007-03-07 00:40:28 +00003032- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003033 makes the filenames the warning module prints much more sensible
3034 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003035
Georg Brandl49aafc92007-03-07 00:34:46 +00003036- Variant of patch #697613: don't exit the interpreter on a SystemExit
3037 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003038 variable is given, but break into the interactive interpreter just
3039 like on other exceptions or normal program exit.

3045 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003046
Georg Brandl0fca97a2007-03-05 22:28:08 +00003047- Patch #1674228: when assigning a slice (old-style), check for the
3048 sq_ass_slice instead of the sq_slice slot.
3049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- When printing an unraisable error, don't print exceptions. before
3051 the name. This duplicates the behavior whening normally printing
3052 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Bug #1653736: Properly discard third argument to

3061 created a weakref on itself during a __del__ call for new-style
3062 classes (classic classes still have the bug).

3675
Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- unittest now verifies more of its assumptions. In particular,

3678 accepted in TestSuite.addTest(). This should cause no
3679 incompatibility since it never made sense with ordinary subclasses
3680 -- the failure just occurred later, with a more cumbersome
3681 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003962- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3963 with RFC 3207 and forgets any knowledge obtained from the server not
3964 obtained from the TLS negotiation itself. Patch contributed by Bill
3965 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003968 that the SMTP.starttls() caller no longer needs to call ehlo()
3969 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003970 does not claim to support starttls. Adds the
3971 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004026- itertools.chain() now has an alternate constructor,

4052 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4053 silently miscode subclasses of those types. Now, it raises a
4054 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004055

Georg Brandl3ee81df2008-05-17 18:14:43 +00004070 time so that opening a database previously created with the DB_DUP
4071 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4072 opens. Specifically: dictionary assignment to a DB object will
4073 replace all values for a given key when the database allows
4074 duplicate values. DB users should use DB.put(k, v) when they want
4075 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004076

4082 characters with ASCII value less than 32. Also, it correctly quotes
4083 dots only if they occur on a single line, as opposed to the previous
4084 behavior of quoting dots if they are the second character of any
4085 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004086

4409
Georg Brandl3ee81df2008-05-17 18:14:43 +00004410- Unified naming convention for free lists and their limits. All free
4411 lists in Object/ are named ``free_list``, the counter ``numfree``
4412 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4413 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004414
Georg Brandl3ee81df2008-05-17 18:14:43 +00004415- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4416 to ``PyTuple_SetItem``, it can be used to populate a brand new
4417 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004418
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004419- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004420
Georg Brandl3ee81df2008-05-17 18:14:43 +00004421- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4422 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4423 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004424
4425- Patch #1720595: add T_BOOL to the range of structmember types.
4426
4427- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4428 ``PyFloat_GetInfo()`` to the float API.
4429
Georg Brandl3ee81df2008-05-17 18:14:43 +00004430- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4431 of w# format code incorrectly truncated the length to an int, even
4432 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4433 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004434
Georg Brandl3ee81df2008-05-17 18:14:43 +00004435- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4436 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004437
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438- PEP 3123: Provide forward compatibility with Python 3.0, while
4439 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4440 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004441
Georg Brandl3ee81df2008-05-17 18:14:43 +00004442- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4443 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004444
4445- Patch #1733960: Allow T_LONGLONG to accept ints.
4446
4447- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4448
Christian Heimes000a0742008-01-03 22:16:32 +00004449- Added a new API function ``PyImport_ImportModuleNoBlock``.
4450
Georg Brandl6caad7d2008-01-26 14:19:22 +00004451- Bug #1637022: Prefix AST symbols with _Py_.
4452
4453- Fix some leftovers from the conversion from int to Py_ssize_t
4454 (relevant to strings and sequences of more than 2**31 items).
4455
4456- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4457 outside of pystate.c and should not be necessary.
4458
Georg Brandl3ee81df2008-05-17 18:14:43 +00004459- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4460 absolute imports. In earlier versions they might have used relative
4461 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004462
Georg Brandl3ee81df2008-05-17 18:14:43 +00004463- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4464 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004465
Georg Brandl3ee81df2008-05-17 18:14:43 +00004466- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4467 macro so it can be used as an expression.

4472
Georg Brandl3ee81df2008-05-17 18:14:43 +00004473- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4474 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4475 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4476 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004477
Georg Brandl3ee81df2008-05-17 18:14:43 +00004478- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4479 _CRT_NONSTDC_NO_DEPRECATE.
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00004480
Martin v. Löwisd476a402007-10-12 08:56:52 +00004481- Bug #1216: Restore support for Visual Studio 2002.

Brett Cannon791d56f2007-05-31 19:40:42 +00004489- buildtools now raises a DeprecationWarning.
4490
Georg Brandl3ee81df2008-05-17 18:14:43 +00004491- Removed the macfs module. It had been deprecated since Python 2.5.
4492 This lead to the deprecation of macostools.touched() as it relied
4493 solely on macfs and was a no-op under OS X.
