Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +000037 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
38 although under Windows it fails at a later point.
Antoine Pitrou5651eaa2008-09-06 20:46:58 +000039
Benjamin Peterson791dc2f2008-09-05 23:27:15 +000040- Issue #3279: Importing site at interpreter was failing silently because the
41 site module uses the open builtin which was not initialized at the time.
42
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000043- Issue #3660: Corrected a reference leak in str.encode() when the encoder
44 does not return a bytes object.
45
46- Issue #3774: Added a few more checks in PyTokenizer_FindEncoding to handle
Amaury Forgeot d'Arc1b933ed2008-09-04 22:34:09 +000047 error conditions.
48
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000049- Issue #3594: Fix Parser/tokenizer.c:fp_setreadl() to open the file being
Brett Cannon8a9583e2008-09-04 05:04:25 +000050 tokenized by either a file path or file pointer for the benefit of
51 PyTokenizer_FindEncoding().
52
Antoine Pitroufff95302008-09-03 18:58:51 +000053- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
54 these systems, the mbstowcs() function is slightly buggy and must be
55 replaced with strlen() for the purpose of counting of number of wide
56 characters needed to represent the multi-byte character string.
57
Antoine Pitrou658fad82008-09-03 18:34:34 +000058- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"
59 could be easily encountered under Windows in debug mode when exercising
60 the recursion limit checking code, due to bogus handling of recursion
61 limit when USE_STACKCHEK was enabled.
62
Brett Cannon54bd41d2008-09-02 04:01:42 +000063- Issue 3639: The _warnings module could segfault the interpreter when
64 unexpected types were passed in as arguments.
65
Antoine Pitrouc6b09eb2008-09-01 15:10:14 +000066- Issue #3712: The memoryview object had a reference leak and didn't support
67 cyclic garbage collection.

70 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
71 was correctly parsed but parsing of subsequent arguments failed.
72
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +000073- Issue #3611: An exception __context__ could be cleared in a complex pattern
74 involving a __del__ method re-raising an exception.

Antoine Pitrouec569b72008-08-26 22:40:48 +000076- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
77 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
78 mechanism. In the process, fix a bug where isinstance() and issubclass(),
79 when given a tuple of classes as second argument, were looking up
80 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
81 type object.
82
Antoine Pitroue2dffc02008-08-26 22:02:58 +000083- Issue #3663: Py_None was decref'd when printing SyntaxErrors.

136 tkinter.BaseWidget and tkinter.scrolledtext.ScrolledText.
137
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000138- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000139 It is now maintained outside of the standard library at

167 exploitation of poor argument checking.
168
Jesus Cea6ba33292008-08-31 14:12:11 +0000169- bsddb code updated to version 4.7.3pre2. This code is the same than
170 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
171 The Python code is automatically translated using "2to3". Please, do not
172 update this code in Python 3.0 by hand. Update the 2.6 one and then
173 do "2to3".
174
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000175- The _bytesio and _stringio modules are now compiled into the python binary.

Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000204Core and Builtins
205-----------------
206
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000207- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
208 arguments.
209
Antoine Pitrou616d2852008-08-19 22:09:34 +0000210- Issue #2394: implement more of the memoryview API, with the caveat that
211 only one-dimensional contiguous buffers are supported and exercised right
212 now. Slicing, slice assignment and comparison (equality and inequality)
213 have been added. Also, the tolist() method has been implemented, but only
214 for byte buffers. Endly, the API has been updated to return bytes objects
215 wherever it used to return bytearrays.
216
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000217- Issue #3560: clean up the new C PyMemoryView API so that naming is
218 internally consistent; add macros PyMemoryView_GET_BASE() and
219 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
220 without relying on a particular implementation; remove the ill-named
221 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
222
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000223- ctypes function pointers that are COM methods have a boolean True
224 value again.
225
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000226- Issue #1819: function calls with several named parameters are now on
227 average 35% faster (as measured by pybench).
228
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000229- The undocumented C APIs PyUnicode_AsString() and
230 PyUnicode_AsStringAndSize() were made private to the interpreter, in
231 order to be able to refine their interfaces for Python 3.1.
232
233 If you need to access the UTF-8 representation of a Unicode object
234 as bytes string, please use PyUnicode_AsUTF8String() instead.
235
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000236- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
237 to Python 3.0's stricter semantics which allow to avoid successive
238 reallocations of the result string (this also affects str.join()).

242-------
243
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000244- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
245 a build problem on MacOS with CJK locales. It adds four temporary
246 mappings to existing legacy codecs that are virtually compatible
247 with Mac encodings. They will be replaced by codecs correctly
248 implemented in 3.1.
249
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000250- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
251 "global name 'header' is not defined".
252
Antoine Pitroufd036452008-08-19 17:56:33 +0000253- Issue #2834: update the regular expression library to match the unicode
254 standards of py3k. In other words, mixing bytes and unicode strings
255 (be it as pattern, search string or replacement string) raises a TypeError.
256 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
257 and can be disabled by specifying a new re.ASCII flag; as for bytes
258 patterns, ASCII matching is the only option and trying to specify re.UNICODE
259 for such patterns raises a ValueError.
260
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000261- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
262 Code contributed by Matt Giuca. quote() now encodes the input
263 before quoting, unquote() decodes after unquoting. There are
264 new arguments to change the encoding and errors settings.
265 There are also new APIs to skip the encode/decode steps.
266 [un]quote_plus() are also affected.
267
Nick Coghlan36f49522008-08-18 12:31:52 +0000268- Issue #2235: numbers.Number now blocks inheritance of the default id()
269 based hash because that hash mechanism is not correct for numeric types.
270 All concrete numeric types that inherit from Number (rather than just
271 registering with it) must explicitly provide a hash implementation in
272 order for their instances to be hashable.
273
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000274- Issue #2676: in the email package, content-type parsing was hanging on
275 pathological input because of quadratic or exponential behaviour of a
276 regular expression.
277
Antoine Pitrou87695762008-08-14 22:44:29 +0000278- Issue #3476: binary buffered reading through the new "io" library is now
279 thread-safe.
280
Robert Schuppenies3d1c7de2008-08-10 11:28:17 +0000281- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
282 menu entries were not deleted.
283
Lars Gustäbel0c24e8b2008-08-02 11:43:24 +0000284- Remove the TarFileCompat class from tarfile.py.
285
Amaury Forgeot d'Arcbdbddf82008-08-01 00:06:49 +0000286- Issue #2491: os.fdopen is now almost an alias for the built-in open(), and
287 accepts the same parameters. It just checks that its first argument is an
288 integer.
289
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000290- Issue #3394: zipfile.writestr sets external attributes when passed a
291 file name rather than a ZipInfo instance, so files are extracted with
292 mode 0600 rather than 000 under Unix.
293
Antoine Pitrouc66f9092008-07-28 19:46:11 +0000294- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
295 asking for a specific length.

312 numbers to and from hexadecimal strings, respectively.
313
Eric Smithd68af8f2008-07-16 00:15:35 +0000314- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
315 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
316
Amaury Forgeot d'Arca4db6862008-07-04 21:26:43 +0000317- Issue #3280: like chr(), the "%c" format now accepts unicode code points
318 beyond the Basic Multilingual Plane (above 0xffff) on all configurations. On
319 "narrow Unicode" builds, the result is a string of 2 code units, forming a
320 UTF-16 surrogate pair.
321
Georg Brandld52429f2008-07-04 15:55:02 +0000322- Issue #3282: str.isprintable() should return False for undefined

Guido van Rossumdc21db32008-04-07 18:37:41 +0000629- "make install" is now an alias for "make altinstall", to prevent
Georg Brandl52b92cc2008-05-25 09:43:03 +0000630 accidentally overwriting a Python 2.x installation. Use "make

649-----------------
650
Neal Norwitz6cf49cf2008-03-24 06:22:57 +0000651- The dl module was removed, use the ctypes module instead.
652
Martin v. Löwis92fab752008-03-08 10:40:41 +0000653- Use wchar_t functions in _locale module.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000658- The class distutils.commands.build_py.build_py_2to3 can be used as a
659 build_py replacement to automatically run 2to3 on modules that are
660 going to be installed.
Martin v. Löwis73a22f02008-03-22 00:35:10 +0000661
Guido van Rossumf4169812008-03-17 22:56:06 +0000662- A new pickle protocol (protocol 3) is added with explicit support
663 for bytes. This is the default protocol. It intentionally cannot
664 be unpickled by Python 2.x.
665
666- When a pickle written by Python 2.x contains an (8-bit) str
667 instance, this is now decoded to a (Unicode) str instance. The
668 encoding used to do this defaults to ASCII, but can be overridden
669 via two new keyword arguments to the Unpickler class. Previously
670 this would create bytes instances, which is usually wrong: str
671 instances are often used to pickle attribute names etc., and text is
672 more common than binary data anyway.
673
Martin v. Löwis071ef772008-03-08 11:24:24 +0000674- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000675 system doesn't support CODESET and LANG isn't set or doesn't allow
676 deduction of an encoding.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000681- Issue #719888: Updated tokenize to use a bytes API. generate_tokens
682 has been renamed tokenize and now works with bytes rather than
683 strings. A new detect_encoding function has been added for
684 determining source file encoding according to PEP-0263. Token
685 sequences returned by tokenize always start with an ENCODING token
686 which specifies the encoding used to decode the file. This token is
687 used to encode the output of untokenize back to bytes.

720 entries each.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000722- Patch #1953: Added ``sys._compact_freelists()`` and the C API
723 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000724 to compact the internal free lists of pre-allocted ints and floats.
725
726- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000727 Python expected the return type int but the fork familie returns
728 pi_t.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000736- Fixed multiple reinitialization of the Python interpreter. The small
737 int list in longobject.c has caused a seg fault during the third
738 finalization.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000762- Improve some exception messages when Windows fails to load an
763 extension module. Now we get for example '%1 is not a valid Win32
764 application' instead of 'error code 193'. Also use Unicode strings
765 to deal with non-English locales.

Brett Cannon37f7e6e2007-10-26 05:42:09 +0000856- str8 now has the same construction signature as bytes.
857
Georg Brandl52b92cc2008-05-25 09:43:03 +0000858- Comparisons between str and str8 now return False/True for ==/!=.
859 sqlite3 returns str8 when recreating on object from it's __conform__
860 value. The struct module returns str8 for all string-related
861 formats. This was true before this change, but becomes more
862 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000863
Georg Brandl52b92cc2008-05-25 09:43:03 +0000864- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
865 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000866
867- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
868
869- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000870 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000871 `PyUnicode_DecodeFSDefault(char*)` was added.
872
Georg Brandl52b92cc2008-05-25 09:43:03 +0000873- io.open() and _fileio.FileIO have grown a new argument closefd. A
874 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000875
Georg Brandl52b92cc2008-05-25 09:43:03 +0000876- Added a new option -b to issues warnings (-bb for errors) about
877 certain operations between bytes/buffer and str like str(b'') and
878 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000879
Georg Brandl52b92cc2008-05-25 09:43:03 +0000880- The standards streams sys.stdin, stdout and stderr may be None when
881 the when the C runtime library returns an invalid file descriptor
882 for the streams (fileno(stdin) < 0). For now this happens only for
883 Windows GUI apps and scripts started with `pythonw.exe`.

Christian Heimesbce52be2007-11-17 19:08:41 +0000885- Added PCbuild9 directory for VS 2008.
886
Georg Brandl52b92cc2008-05-25 09:43:03 +0000887- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
888 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000889
Georg Brandl52b92cc2008-05-25 09:43:03 +0000890- Unbound methods are gone for good. ClassObject.method returns an
891 ordinary function object, instance.method still returns a bound
892 method object. The API of bound methods is cleaned up, too. The
893 im_class attribute is removed and im_func + im_self are renamed to
894 __func__ and __self__. The factory PyMethod_New takes only func and
895 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000896
Georg Brandl52b92cc2008-05-25 09:43:03 +0000897- intobject.h is no longer included by Python.h. The remains were
898 moved to longobject.h. It still exists to define several aliases
899 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000900
Christian Heimesa37d4c62007-12-04 23:02:19 +0000901- Removed sys.maxint, use sys.maxsize instead.

910
Georg Brandl52b92cc2008-05-25 09:43:03 +0000911- When loading an external file using testfile(), the passed-in
912 encoding argument was being ignored if __loader__ is defined and
913 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000914
Georg Brandl52b92cc2008-05-25 09:43:03 +0000915- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
916 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000917

Neal Norwitz4886cc32006-08-21 17:06:07 +0000928
929Core and Builtins
930-----------------
931
Martin v. Löwis47383402007-08-15 07:32:56 +0000932- PEP 3131: Support non-ASCII identifiers.
933
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000934- PEP 3120: Change default encoding to UTF-8.
935
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000936- PEP 3123: Use proper C inheritance for PyObject.
937
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000938- Removed the __oct__ and __hex__ special methods and added a bin()
939 builtin function.
940
Georg Brandl52b92cc2008-05-25 09:43:03 +0000941- PEP 3127: octal literals now start with "0o". Old-style octal
942 literals are invalid. There are binary literals with a prefix of
943 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000944
Guido van Rossume7ba4952007-06-06 23:52:48 +0000945- None, True, False are now keywords.
946
Guido van Rossum29478ef2007-05-29 00:39:44 +0000947- PEP 3119: isinstance() and issubclass() can be overridden.
948
Guido van Rossumebe3e162007-05-17 18:20:34 +0000949- Remove BaseException.message.
950
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000951- Remove tuple parameter unpacking (PEP 3113).
952
Georg Brandl52b92cc2008-05-25 09:43:03 +0000953- Remove the f_restricted attribute from frames. This naturally leads
954 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000955
Georg Brandl52b92cc2008-05-25 09:43:03 +0000956- PEP 3132 was accepted. That means that you can do ``a, *b =
957 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000958
Georg Brandl52b92cc2008-05-25 09:43:03 +0000959- range() now returns an iterator rather than a list. Floats are not
960 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000961
Nick Coghlan650f0d02007-04-15 12:05:43 +0000962- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000963 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000964
Guido van Rossume27dc722007-03-27 22:37:34 +0000965- By default, != returns the opposite of ==, unless the latter returns
966 NotImplemented.
967
Georg Brandl52b92cc2008-05-25 09:43:03 +0000968- Patch #1680961: sys.exitfunc has been removed and replaced with a
969 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000970
Georg Brandl801dd732007-03-18 20:18:31 +0000971- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000972 keyword arg in the class statement, which can now use the full
973 syntax of a parameter list. Also, the metaclass can implement a
974 __prepare__ function which will be called to create the dictionary
975 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000976
Georg Brandl428f0642007-03-18 18:35:15 +0000977- The long-deprecated argument "pend" of PyFloat_FromString() has been
978 removed.
979
Georg Brandle32b4222007-03-10 22:13:27 +0000980- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000981 its argument, if it exists. If not, it will work like before. This
982 allows customizing the output of dir() in the presence of a
983 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000984
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000985- Removed support for __members__ and __methods__.
986
Georg Brandle32b4222007-03-10 22:13:27 +0000987- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000988
Georg Brandle32b4222007-03-10 22:13:27 +0000989- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000990 functionality formerly known as raw_input(); the name raw_input() is
991 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000992
Georg Brandl52b92cc2008-05-25 09:43:03 +0000993- Classes listed in an 'except' clause must inherit from
994 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000995
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000996- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000997 and .keys(), .items(), .values() return dict views, which behave
998 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000999
Guido van Rossum8b545362007-02-09 23:52:14 +00001000- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001001 'softspace' attribute of files is now gone (since print() doesn't
1002 use it). A side effect of this change is that you can get
1003 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001004
1005 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001006 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001007
1008 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001009
Brett Cannon398db8b2007-01-29 23:44:37 +00001010- PEP 3102: keyword-only arguments.
1011
Georg Brandl52b92cc2008-05-25 09:43:03 +00001012- Int/Long unification is complete. The 'long' built-in type and
1013 literals with trailing 'L' or 'l' have been removed. Performance
1014 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001015
1016- 'except E, V' must now be spelled as 'except E as V' and deletes V
1017 at the end of the except clause; V must be a simple name.
1018
Neal Norwitzc1505362006-12-28 06:47:50 +00001019- Added function annotations per PEP 3107.
1020
Georg Brandl52b92cc2008-05-25 09:43:03 +00001021- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001022
1023 >>> def f(x):
1024 ... def inc():
1025 ... nonlocal x
1026 ... x += 1
1027 ... return x
1028 ... return inc
1029 ...
1030 >>> inc = f(0)
1031 >>> inc()
1032 1
1033 >>> inc()
1034 2
1035
Georg Brandl66a796e2006-12-19 20:50:34 +00001036- Moved intern() to sys.intern().
1037
1038- exec is now a function.
1039
1040- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001041
Neal Norwitz4886cc32006-08-21 17:06:07 +00001042- Classic classes are a thing of the past. All classes are new style.
1043
1044- Exceptions *must* derive from BaseException.
1045
1046- Integer division always returns a float. The -Q option is no more.
1047 All the following are gone:
1048 * PyNumber_Divide and PyNumber_InPlaceDivide
1049 * __div__, __rdiv__, and __idiv__
1050 * nb_divide, nb_inplace_divide
1051 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1052 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1053 if we want to re-use __div__ and friends. If we do, it will make
1054 it harder to write code for both 2.x and 3.x.)
1055
1056- 'as' and 'with' are keywords.
1057
1058- Absolute import is the default behavior for 'import foo' etc.
1059
Georg Brandl52b92cc2008-05-25 09:43:03 +00001060- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001061
Georg Brandl52b92cc2008-05-25 09:43:03 +00001062- Removed these Python builtins: apply(), callable(), coerce(),
1063 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001064
Georg Brandl52b92cc2008-05-25 09:43:03 +00001065- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001066
Georg Brandl52b92cc2008-05-25 09:43:03 +00001067- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001068
1069- Remove C API support for restricted execution.
1070
Guido van Rossumcf1be882007-08-30 22:07:17 +00001071- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001072 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001073 sequences of unequal length -- it now stops after the shortest one
1074 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001075
Georg Brandl52b92cc2008-05-25 09:43:03 +00001076- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001077
1078- Added class decorators per PEP 3129.

Georg Brandl52b92cc2008-05-25 09:43:03 +00001084- Removed the imageop module. Obsolete long with its unit tests
1085 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +00001086
Georg Brandl52b92cc2008-05-25 09:43:03 +00001087- Removed these attributes from the operator module: div, idiv,

Guido van Rossumd59da4b2007-05-22 18:11:13 +00001114
Georg Brandl52b92cc2008-05-25 09:43:03 +00001115- Removed support for long obsolete platforms: plat-aix3, plat-irix5.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001116
Georg Brandl52b92cc2008-05-25 09:43:03 +00001117- Removed xmlrpclib.SlowParser. It was based on xmllib.
