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

460- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
461 302 conformant loader) will now work correctly in most cases (they
462 are still subject to the constraints that exist for all code running
463 from inside a module loaded via a PEP 302 loader and attempting to

626==========================
627
628*Release date: 04-Dec-2008*
629
630Core and Builtins
631-----------------
632
633- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
634 interpreter to abort ("Fatal Python error: Could not reset the stack!")
635 instead of throwing a MemoryError.
636
637- Issue #4367: Python would segfault during compiling when the unicodedata
638 module couldn't be imported and \N escapes were present.
639
640- Issue #4348: Some bytearray methods returned that didn't cause any change to
641 the bytearray, returned the same bytearray instead of a copy.
642
643- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
644
645- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
646
647- Issue #4048: The parser module now correctly validates relative imports.
648
649- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
650 exec statement.
651
652- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
653 method does not return iterators for the 4th and 5th items.
654
655- Issue #4209: Enabling unicode_literals and the print_function in the same
656 __future__ import didn't work.
657
658- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
659 returned a path longer than MAX_PATH. (But It's doubtful this code path is

816
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000817- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
818 PyString_FromFormat or PyErr_Format to display size_t values. The macro
819 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
820 ``printf`` function, whereas PyString_FromFormat has an independent
821 implementation and uses "%zd" on all platforms for size_t values.
822 This makes a difference on win64, where ``printf`` needs "%Id" to display
823 64bit values.

841
Vinay Sajip35e3b032008-09-01 14:33:59 +0000842- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000843 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
844 mechanism. In the process, fix a bug where isinstance() and issubclass(),
845 when given a tuple of classes as second argument, were looking up
846 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
847 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000983What's New in Python 2.6 beta 3?
984================================
985
Barry Warsaw07a4a382008-08-21 01:15:08 +0000986*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000987
988Core and Builtins
989-----------------
990
Guido van Rossumf8402962008-08-20 15:01:50 +0000991- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
992 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
993 extensions do not automatically benefit from the class attribute
994 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
995 to their tp_flags field if they care. This is a backwards
996 compatibility feature; in 3.0, all types will use the cache by
997 default.
998
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000999- Keyword arguments can now follow starred arguments. (``f(a, *args,
1000 keyword=23)`` is now valid syntax.)
1001
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001002- ctypes function pointers that are COM methods have a boolean True
1003 value again.
1004
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001005- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1006 by denying s# to parse objects that have a releasebuffer procedure,
1007 and introducing s*.
1008
Georg Brandl1e13ea92008-08-11 09:07:59 +00001009- Issue #3537: Fix an assertion failure when an empty but presized dict
1010 object was stored in the freelist.
1011
Mark Dickinsonb6467572008-08-04 21:30:09 +00001012- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1013 ValueError consistently across platforms.
1014
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001015- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1016 (64bit Unix, for example), unichr() would truncate its argument and return
1017 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1018
Neal Norwitze7d8be82008-07-31 17:17:14 +00001019- Apply security patches from Apple.
1020
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001021- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1022 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1023
Antoine Pitrou92f82162008-07-25 22:22:08 +00001024- Issue #1819: function calls with several named parameters are now on
1025 average 35% faster (as measured by pybench).
1026
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001027- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1028 the python debugger steps into a class statement: the free variables (local
1029 variables defined in an outer scope) would be deleted from the outer scope.
1030
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001031- Issue #2620: Overflow checking when allocating or reallocating memory
1032 was not always being done properly in some python types and extension
1033 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1034 all been updated to perform better checks and places in the code that
1035 would previously leak memory on the error path when such an allocation
1036 failed have been fixed.
1037
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001038Library
1039-------
1040
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001041- Issue #3612: Added some missing basic types in ctypes.wintypes.
1042
Benjamin Petersone977ad42008-08-20 01:42:01 +00001043- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1044 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1045
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001046- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1047 version reported by these tools does not necessarily follow the python
1048 version numbering scheme, so the module is less strict when parsing it.
1049
Nick Coghlanf70385a2008-08-18 12:42:46 +00001050- Issue #2235: Added Py3k warnings for types which will become unhashable
1051 under the stricter __hash__ inheritance rules in 3.0. Several types
1052 which did not meet the rules for hash invariants and were already
1053 unhashable in 3.0 have now been explicitly flagged as unhashable in
1054 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1055 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1056
Brett Cannon88f801d2008-08-18 00:46:22 +00001057- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1058 imported into the module but exposed as part of the module's API.
1059
Brett Cannon7b96f072008-08-18 00:41:11 +00001060- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1061
Brett Cannon46225e72008-08-18 00:36:52 +00001062- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001064- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1065
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001066- Issue #3575: Incremental decoder's decode function now takes bytearray
1067 by using 's*' instead of 't#'.
1068
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001069- Issue #2222: Fixed reference leak when occured os.rename()
1070 fails unicode conversion on 2nd parameter. (windows only)
1071
Facundo Batista94f243a2008-08-17 03:38:39 +00001072- Issue 2464. urllib2 now supports a malformation in the URL received
1073 in a redirect.
1074
Brett Cannonabe423e2008-08-16 21:47:07 +00001075- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001076 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001077
Facundo Batistaeb90b782008-08-16 14:44:07 +00001078- Issue #2776: fixed small issue when handling an URL with double slash
1079 after a 302 response in the case of not going through a proxy.
1080
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001081- Issue #2676: in the email package, content-type parsing was hanging on
1082 pathological input because of quadratic or exponential behaviour of a
1083 regular expression.
1084
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001085- Issue #3476: binary buffered reading through the new "io" library is now
1086 thread-safe.
1087
Brett Cannonbf3157b2008-08-14 05:00:03 +00001088- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1089 since mimetools itself is deprecated. Because modules are cached, all
1090 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1091
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001092- Issue #3134: shutil referenced undefined WindowsError symbol.
1093
Robert Schuppenies14646332008-08-10 11:01:53 +00001094- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1095 menu entries were not deleted.
1096
Brett Cannon83e81842008-08-09 23:30:55 +00001097- Copied the implementation of reduce() to _functools.reduce() to have a
1098 version that did not raise a DeprecationWarning under -3.
1099
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001100- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1101 a MemoryError rather than silently stop the iteration.
1102
Guido van Rossum59ce9012008-08-09 14:55:34 +00001103- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1104 to _sre.compile() will now be rejected. This should not affect anybody
1105 since the re.compile() function never generates invalid re-bytecode.
1106
Skip Montanaroa032bf42008-08-08 22:52:51 +00001107- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1108 upon first access it can be automatically initialized from the csv file if
1109 it wasn't initialized during instantiation.
1110
Brett Cannon3aa2a492008-08-06 22:28:09 +00001111- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1112 the reload() built-in has been removed.
1113
Brett Cannon7e30b672008-08-04 21:52:25 +00001114- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001115 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001116 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1117 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1118 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1119 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1120 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001121
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001122- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1123 raised an AttributeError.
1124
Benjamin Peterson01a24322008-07-28 23:35:27 +00001125- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001126 asking for a specific length. This problem only affected files opened
1127 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001128
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001129- Issue #3449: Update decimal module to use most recent specification
1130 (v. 1.68) and tests (v. 2.58) from IBM.
1131
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001132- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1133

1140
1141- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1142 invalid arguments.
1143
1144- Issue #3302: Fix several crashes when calling locale's gettext functions
1145 with None arguments.
1146
1147- Issue #3389: Allow resolving dotted names for handlers in logging
1148 configuration files.
1149
1150- Deprecate the sunaudio module for removal in Python 3.0.
1151
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001152- Issue #3394: zipfile.writestr sets external attributes when passed a
1153 file name rather than a ZipInfo instance, so files are extracted with
1154 mode 0600 rather than 000 under Unix.
1155
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001156- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1157 argument in python 2.5, this broke code that subclassed Popen to include its
1158 own poll method. Fixed my moving _deadstate to an _internal_poll method.
1159

1166-------------
1167
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001168- Issue #2235: the C API function PyObject_HashNotImplemented and its
1169 interaction with the tp_hash slot (added in 2.6b2) are now documented
1170
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001171- Issue #643841: The language reference now provides more detailed
1172 coverage of the lookup process for special methods. The disclaimers
1173 regarding lack of coverage of new-style classes have also been
1174 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001177What's New in Python 2.6 beta 2?
1178================================
1179
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001180*Release date: 17-Jul-2008*
1181
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001182Core and Builtins
1183-----------------
1184
Georg Brandl3e483f62008-07-16 22:57:41 +00001185- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1186 its methods now allow for items objects that can be converted to
1187 an integer using operator.index().
1188
Mark Dickinson64b7e502008-07-16 09:40:03 +00001189- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1190 produced a ValueError instead of giving the correct float.
1191
Eric Smitha5fa5a22008-07-16 00:11:49 +00001192- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1193 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1194
Mark Dickinson7103aa42008-07-15 19:08:33 +00001195- Issue #3008: the float type has a new instance method 'float.hex'
1196 and a new class method 'float.fromhex' to convert floating-point
1197 numbers to and from hexadecimal strings, respectively.
1198
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001199- Issue #2235: __hash__ is once again inherited by default. To allow
1200 collections.Hashable to remain meaningful in the presence of the
1201 default hash implementation (object.__hash__), it is now possible
1202 to explicit block inheritance of hash by setting __hash__=None at
1203 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1204 level.
1205
Nick Coghlanb028f502008-07-13 14:52:36 +00001206- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1207 the parent module cannot be found while performing an absolute import.
1208 This means that an incorrectly defined __package__ attribute will
1209 now only prevent relative imports in that module rather than causing
1210 all imports from that module to fail.
1211
Nick Coghlan14ff9942008-07-08 14:21:42 +00001212- Issue #2517: Allow unicode messages in Exceptions again by correctly
1213 bypassing the instance dictionary when looking up __unicode__ on
1214 new-style classes.
1215
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001216- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1217 set to a custom object whose write() method happens to install
1218 another file in sys.stdout.
1219
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001220- Issue #3088: Corrected a race condition in classes derived from
1221 threading.local: the first member set by a thread could be saved in
1222 another thread's dictionary.
1223
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001224- Issue #3004: Minor change to slice.indices(): the start and stop
1225 arguments are now treated identically, making the behaviour easier
1226 to describe and understand. For example, slice(None, -10,
1227 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1228 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1229 10, -1).
1230
Georg Brandl278fc502008-07-19 12:46:12 +00001231- Issue #3219: Calling a function with repeated keyword arguments,
1232 f(a=2, a=23), would not cause a syntax error. This was a regression
1233 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001234
Georg Brandl278fc502008-07-19 12:46:12 +00001235- Issue #2862: Make int and float freelist management consistent with
1236 other freelists. Changes their CompactFreeList apis into
1237 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001238

1240-------
1241
Thomas Heller57adf222008-08-14 19:10:48 +00001242- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1243 api functions without holding the GIL, which could lead to a fatal
1244 error when they failed.
1245
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001246- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1255 ForkingPickler.register() to resolve conflict with ctypes.
1256
Vinay Sajip51e65192008-07-18 09:01:10 +00001257- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

1260 a valid dlerror() message.
1261
Thomas Heller2bad6572008-07-15 17:19:50 +00001262- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1263 incomplete structure was created.
1264
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001265- Issue #3339: dummy_thread.acquire() should not return None.
1266
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001267- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1268

1682 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001683 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001684
1685 This is controlled by the configure argument ``--with-universal-archs``:
1686
1687 - ``--with-universal-archs=all``: install 4-way universal
1688
1689 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1690
1691 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1692
1693 This option should be used in combination with ``--enable-universalsdk=``.
1694
1695 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 +00001731- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
1732 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00001733
Christian Heimese74c8f22008-04-19 02:23:57 +00001734- Added kill, terminate and send_signal(sig) to subprocess.Popen.
1735
Georg Brandl3ee81df2008-05-17 18:14:43 +00001736- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
1737 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00001738
Georg Brandl3ee81df2008-05-17 18:14:43 +00001739- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00001745- Issue #1631171: Re-implement the 'warnings' module in C (the
1746 original Python code has been kept as backup). This will allow for
1747 using the 'warning's machinery in such places as the parser where
1748 use of pure Python code is not possible. Both the ``showarning()``
1749 and ``formatwarning()`` gain an optional 'line' argument which is
1750 not called by default for backwards-compatibility reasons. Setting
1751 ``warnings.showwarning()`` to an implementation that lacks support
1752 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00001775 reference to themselves.
1776
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001777- The getpass module has been improved on Unix. It now uses /dev/tty
1778 by default and uses stderr instead of stdout. A GetPassWarning is
1779 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00001780

1792 removed and replaced by pure python code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001794- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001795 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001815- Issue #2550: The approach used by client/server code for obtaining
1816 ports to listen on in network-oriented tests has been refined in an
1817 effort to facilitate running multiple instances of the entire
1818 regression test suite in parallel without issue.
1819 test_support.bind_port() has been fixed such that it will always
1820 return a unique port -- which wasn't always the case with the
1821 previous implementation, especially if socket options had been set
1822 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1823 new implementation of bind_port() will actually raise an exception
1824 if it is passed an AF_INET/SOCK_STREAM socket with either the
1825 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1826 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1827 the socket it's been passed. This currently only applies to
1828 Windows. This option prevents any other sockets from binding to the
1829 host/port we've bound to, thus removing the possibility of the
1830 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1831 when a second SOCK_STREAM socket binds and accepts to a host/port
1832 that's already been bound by another socket. The optional preferred
1833 port parameter to bind_port() has been removed. Under no
1834 circumstances should tests be hard coding ports!
1835
1836 test_support.find_unused_port() has also been introduced, which will
1837 pass a temporary socket object to bind_port() in order to obtain an
1838 unused port. The temporary socket object is then closed and
1839 deleted, and the port is returned. This method should only be used
1840 for obtaining an unused port in order to pass to an external program
1841 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1842 a parameter to a server-oriented class that doesn't give you direct
1843 access to the underlying socket used.
1844
1845 Finally, test_support.HOST has been introduced, which should be used
1846 for the host argument of any relevant socket calls (i.e. bind and
1847 connect).

2121Core and builtins
2122-----------------
2123
Fred Drakea8ee94b2008-03-01 02:45:07 +00002124- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002125 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002126
Georg Brandlad61bc82008-02-23 15:11:18 +00002127- Issue #2067: file.__exit__() now calls subclasses' close() method.
2128
2129- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002130
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002131- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002132 issue 215555 for a discussion.
2133
Eric Smitha73fbe72008-02-23 03:09:44 +00002134- Added the future_builtins module, which contains hex() and oct().
2135 These are the PEP 3127 version of these functions, designed to be
2136 compatible with the hex() and oct() builtins from Python 3.0. They
2137 differ slightly in their output formats from the existing, unchanged
2138 Python 2.6 builtins. The expected usage of the future_builtins
2139 module is:
2140 from future_builtins import hex, oct
2141
Eric Smith7ef40bf2008-02-20 23:34:22 +00002142- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2143 exponents for exponents with absolute value < 100. Follows C99
2144 standard. This is a change on Windows, which would use 3 digits.
2145 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2146 so that any alterations it does to the resulting string will be
2147 available in stringlib/formatter.h (for float.__format__).
2148
Eric Smith5a3c1352008-02-19 13:21:56 +00002149- Implemented PEP 3101, Advanced String Formatting. This adds a new
2150 builtin format(); a format() method for str and unicode; a
2151 __format__() method to object, str, unicode, int, long, float, and
2152 datetime; the class string.Formatter; and the C API
2153 PyObject_Format().
2154
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155- Fixed several potential crashes, all caused by specially crafted
2156 __del__ methods exploiting objects in temporarily inconsistent
2157 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002158
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002159- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002160 prevent a possible crash: an Abstract Base Class would try to access
2161 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002162
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163- Fixed repr() and str() of complex numbers with infinity or nan as
2164 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002165
Georg Brandl3ee81df2008-05-17 18:14:43 +00002166- Clear all free lists during a gc.collect() of the highest generation
2167 in order to allow pymalloc to free more arenas. Python may give back
2168 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002169
Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Issue #2045: Fix an infinite recursion triggered when printing a
2171 subclass of collections.defaultdict, if its default_factory is set
2172 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002173
Christian Heimesf75dbef2008-02-08 00:11:31 +00002174- Fixed a minor memory leak in dictobject.c. The content of the free
2175 list was not freed on interpreter shutdown.
2176
Georg Brandl3ee81df2008-05-17 18:14:43 +00002177- Limit free list of method and builtin function objects to 256
2178 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2181 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002182 to compact the internal free lists of pre-allocted ints and floats.
2183
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2185 calls. Python expected the return type int but the fork familie
2186 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002187
Georg Brandl3ee81df2008-05-17 18:14:43 +00002188- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2189 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002190
Georg Brandl3ee81df2008-05-17 18:14:43 +00002191- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2192 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002193
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2195 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002196
Georg Brandl3ee81df2008-05-17 18:14:43 +00002197- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2198 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002199
Georg Brandl3ee81df2008-05-17 18:14:43 +00002200- Patch #1473257: generator objects gain a gi_code attribute. This is
2201 the same object as the func_code attribute of the function that
2202 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Issue #1920: "while 0" statements were completely removed by the
2205 compiler, even in the presence of an "else" clause, which is
2206 supposed to be run when the condition is false. Now the compiler
2207 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002208
Guido van Rossumeead05f2008-01-24 18:21:02 +00002209- A few crashers fixed: weakref_in_del.py (issue #1377858);
2210 loosing_dict_ref.py (issue #1303614, test67.py);
2211 borrowed_ref_[34].py (not in tracker).
2212
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002213- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002214 suppressed while an extension is loaded by calling SetErrorMode in
2215 dynload_win.c. The error is still reported properly.
2216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002218 several extension methods and modules do not work without unicode
2219 support.
2220
Georg Brandl26543b12008-01-21 18:36:51 +00002221- Issue #1882: when compiling code from a string, encoding cookies in the
2222 second line of code were not always recognized correctly.
2223
Georg Brandl14404b62008-01-19 19:27:05 +00002224- Issue #1679: "0x" was taken as a valid integer literal.
2225
Georg Brandl6caad7d2008-01-26 14:19:22 +00002226- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002227 added.
2228
Christian Heimesc94e2b52008-01-14 04:13:37 +00002229- sys.float_info / PyFloat_GetInfo: The floating point information
2230 object was converted from a dict to a specialized structseq object.
2231
Georg Brandl3ee81df2008-05-17 18:14:43 +00002232- Patch #1816: Added sys.flags structseq. It exposes the status of
2233 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002234
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235- Objects/structseq.c: Implemented new structseq representation. The
2236 patch makes structseqs (e.g. the return value of os.stat) more
2237 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002238
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Patch #1700288: added a type attribute cache that caches method
2240 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002241
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002242- Bug #1776: __import__() no longer accepts filenames on any platform.
2243 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002244
Georg Brandlaed6c662008-01-07 17:25:53 +00002245- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2246
Georg Brandl3ee81df2008-05-17 18:14:43 +00002247- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2248 envvar and sys.dont_write_bytecode attribute. All these can be set
2249 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Improve some exception messages when Windows fails to load an
2252 extension module. Now we get for example '%1 is not a valid Win32
2253 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002257- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2258 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002259
Christian Heimes0a8143f2007-12-18 23:22:54 +00002260- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002261 and INF. float("nan"), float("inf") and float("-inf") now work on
2262 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002263
Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Compiler now generates simpler and faster code for dictionary
2265 literals. The oparg for BUILD_MAP now indicates an estimated
2266 dictionary size. There is a new opcode, STORE_MAP, for adding
2267 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002268
Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Issue #1620: New property decorator syntax was modifying the
2272 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002273
Georg Brandl3ee81df2008-05-17 18:14:43 +00002274- Issue #1538: Avoid copying string in split/rsplit if the split char
2275 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002277- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002278 SystemError.
2279
Nick Coghlanef01d822007-12-03 12:55:17 +00002280- PEP 366: Allow explicit relative imports when executing modules
2281 inside packages with the -m switch via a new module level
2282 __package__ attribute.
2283
Georg Brandl3ee81df2008-05-17 18:14:43 +00002284- Issue #1402: Fix a crash on exit, when another thread is still
2285 running, and if the deallocation of its frames somehow calls the
2286 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002287

2297 file can now be directly executed by passing their name to the
2298 interpreter. The directory/zipfile is automatically inserted as the
2299 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002300
Georg Brandl3ee81df2008-05-17 18:14:43 +00002301- Issue #1265: Fix a problem with sys.settrace, if the tracing
2302 function uses a generator expression when at the same time the
2303 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002304
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002305- sets and frozensets now have an isdisjoint() method.
2306
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002307- optimize the performance of builtin.sum().
2308
Neal Norwitz44f326e2007-10-05 05:29:17 +00002309- Fix warnings found by the new version of the Coverity checker.
2310
Georg Brandl3ee81df2008-05-17 18:14:43 +00002311- The enumerate() builtin function is no longer bounded to sequences
2312 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2313 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002314
Georg Brandl3ee81df2008-05-17 18:14:43 +00002315- Issue #1686386: Tuple's tp_repr did not take into account the
2316 possibility of having a self-referential tuple, which is possible
2317 from C code. Nor did object's tp_str consider that a type's tp_str
2318 could do something that could lead to an inifinite recursion.
2319 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2320 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002321
Georg Brandl3ee81df2008-05-17 18:14:43 +00002322- Issue #1164: It was possible to trigger deadlock when using the
2323 'print' statement to write to a file since the GIL was not released
2324 as needed. Now PyObject_Print() does the right thing along with
2325 various tp_print implementations of the built-in types and those in
2326 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002328- Issue #1147: Exceptions were directly allowing string exceptions in
2329 their throw() method even though string exceptions no longer
2330 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002331
Georg Brandl3ee81df2008-05-17 18:14:43 +00002332- Issue #1096: Prevent a segfault from getting the repr of a very
2333 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002334
Brett Cannon1e534b52007-09-07 04:18:30 +00002335- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002336 PyObject_Call() never calling back out to Python code to trigger
2337 recursion depth updates/checks. Required the creation of a static
2338 RuntimeError instance in case normalizing an exception put the
2339 recursion check value past its limit. Fixes crashers
2340 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002341

Neal Norwitz0ac60192007-05-27 04:08:54 +00002355- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002356 __*__ attributes. (Some already existed, e.g., __doc__ and
2357 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002358
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002359- Add -3 option to the interpreter to warn about features that are
2360 deprecated and will be changed/removed in Python 3.0.
2361
Georg Brandl2134e752007-05-21 20:34:16 +00002362- Patch #1686487: you can now pass any mapping after '**' in function
2363 calls.
2364
Collin Winter62903052007-05-18 23:11:24 +00002365- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002366 "except E as target:". This is to provide forwards compatibility
2367 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002368
Brett Cannon229cee22007-05-05 01:34:02 +00002369- Deprecate BaseException.message as per PEP 352.
2370
Georg Brandl3ee81df2008-05-17 18:14:43 +00002371- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002372 inherited from a builtin base.
2373
Vinay Sajip8549ce32007-05-06 17:53:37 +00002374- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002375 setting a plain string, ie don't expand to single letter identifiers.
2376
Raymond Hettinger13936692007-04-11 18:40:58 +00002377- Request #1191699: Slices can now be pickled.
2378
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002379- Request #1193128: str.translate() now allows a None argument for
2380 translations that only remove characters without re-mapping the
2381 remaining characters.
2382
Georg Brandl5cb76c12007-03-21 09:00:39 +00002383- Patch #1682205: a TypeError while unpacking an iterable is no longer
2384 masked by a generic one with the message "unpack non-sequence".
2385
Neal Norwitzaa754b72007-03-21 06:39:48 +00002386- Remove unused file Python/fmod.c.
2387
Guido van Rossum143b5642007-03-23 04:58:42 +00002388- Bug #1683368: The object.__init__() and object.__new__() methods are
2389 now stricter in rejecting excess arguments. The only time when
2390 either allows excess arguments is when it is not overridden and the
2391 other one is. For backwards compatibility, when both are
2392 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002393 warning later). Also, type.__init__() insists on the same signature
2394 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2397 object to complex using its __complex__() method before falling back
2398 to the __float__() method. Therefore, the functions in the cmath
2399 module now can operate on objects that define a __complex__()
2400 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002401
Georg Brandl3ee81df2008-05-17 18:14:43 +00002402- Patch #1623563: allow __class__ assignment for classes with
2403 __slots__. The old and the new class are still required to have the
2404 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002405

2410 ``object.__reduce_ex__()`` is called with an object that is faking
2411 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002412
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413- Patch #1680015: Don't modify __slots__ tuple if it contains an

2417
Georg Brandl7b9c5552007-03-12 14:30:05 +00002418- Bug #1678647: write a newline after printing an exception in any
2419 case, even when converting the value to a string failed.
2420
Georg Brandl871f1bc2007-03-12 13:17:36 +00002421- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002422 its argument, if it exists. If not, it will work like before. This
2423 allows customizing the output of dir() in the presence of a
2424 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002425
Collin Winter276887b2007-03-12 16:11:39 +00002426- Patch #922167: Python no longer segfaults when faced with infinitely
2427 self-recursive reload() calls (as reported by bug #742342).
2428

2433 parthensized forms. This means complex(repr(x)) now works instead of
2434 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002435
Georg Brandlaa2321b2007-03-07 00:40:28 +00002436- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002437 makes the filenames the warning module prints much more sensible
2438 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002439
Georg Brandl49aafc92007-03-07 00:34:46 +00002440- Variant of patch #697613: don't exit the interpreter on a SystemExit
2441 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002442 variable is given, but break into the interactive interpreter just
2443 like on other exceptions or normal program exit.

2449 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002450
Georg Brandl0fca97a2007-03-05 22:28:08 +00002451- Patch #1674228: when assigning a slice (old-style), check for the
2452 sq_ass_slice instead of the sq_slice slot.
2453
Georg Brandl3ee81df2008-05-17 18:14:43 +00002454- When printing an unraisable error, don't print exceptions. before
2455 the name. This duplicates the behavior whening normally printing
2456 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002464- Bug #1377858: Fix the segfaulting of the interpreter when an object
2465 created a weakref on itself during a __del__ call for new-style
2466 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00002467

3065 Python would crash instead of raising an error.
3066
Thomas Hellerc2f77252007-03-09 19:21:28 +00003067- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
3068 returned string up to the first NUL character.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003080- unittest now verifies more of its assumptions. In particular,
3081 TestCase and TestSuite subclasses (not instances) are no longer
3082 accepted in TestSuite.addTest(). This should cause no
3083 incompatibility since it never made sense with ordinary subclasses
3084 -- the failure just occurred later, with a more cumbersome
3085 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3367 with RFC 3207 and forgets any knowledge obtained from the server not
3368 obtained from the TLS negotiation itself. Patch contributed by Bill
3369 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003370
Georg Brandl3ee81df2008-05-17 18:14:43 +00003371- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003372 that the SMTP.starttls() caller no longer needs to call ehlo()
3373 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003374 does not claim to support starttls. Adds the
3375 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3456 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3457 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003474 time so that opening a database previously created with the DB_DUP
3475 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3476 opens. Specifically: dictionary assignment to a DB object will
3477 replace all values for a given key when the database allows
3478 duplicate values. DB users should use DB.put(k, v) when they want
3479 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003480

3486 characters with ASCII value less than 32. Also, it correctly quotes
3487 dots only if they occur on a single line, as opposed to the previous
3488 behavior of quoting dots if they are the second character of any
3489 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003490

Neal Norwitz92422fb2006-08-18 03:57:54 +00003811C API
3812-----
3813
Georg Brandl3ee81df2008-05-17 18:14:43 +00003814- Unified naming convention for free lists and their limits. All free
3815 lists in Object/ are named ``free_list``, the counter ``numfree``
3816 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3817 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003818
Georg Brandl3ee81df2008-05-17 18:14:43 +00003819- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3820 to ``PyTuple_SetItem``, it can be used to populate a brand new
3821 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003822
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003823- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003825- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3826 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3827 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003828
3829- Patch #1720595: add T_BOOL to the range of structmember types.
3830
3831- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3832 ``PyFloat_GetInfo()`` to the float API.
3833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3835 of w# format code incorrectly truncated the length to an int, even
3836 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3837 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003838
Georg Brandl3ee81df2008-05-17 18:14:43 +00003839- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3840 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003842- PEP 3123: Provide forward compatibility with Python 3.0, while
3843 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3844 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3847 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003848
3849- Patch #1733960: Allow T_LONGLONG to accept ints.
3850
3851- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3852

3856
3857- Fix some leftovers from the conversion from int to Py_ssize_t
3858 (relevant to strings and sequences of more than 2**31 items).
3859
3860- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3861 outside of pystate.c and should not be necessary.
3862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3864 absolute imports. In earlier versions they might have used relative
3865 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3868 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3871 macro so it can be used as an expression.

3876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3878 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3879 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3880 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Removed the macfs module. It had been deprecated since Python 2.5.
3896 This lead to the deprecation of macostools.touched() as it relied
3897 solely on macfs and was a no-op under OS X.
