Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +000080 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
81 although under Windows it fails at a later point.
Antoine Pitrou5651eaa2008-09-06 20:46:58 +000082
Benjamin Peterson791dc2f2008-09-05 23:27:15 +000083- Issue #3279: Importing site at interpreter was failing silently because the
84 site module uses the open builtin which was not initialized at the time.

Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000092- Issue #3594: Fix Parser/tokenizer.c:fp_setreadl() to open the file being
Brett Cannon8a9583e2008-09-04 05:04:25 +000093 tokenized by either a file path or file pointer for the benefit of
94 PyTokenizer_FindEncoding().
95
Antoine Pitroufff95302008-09-03 18:58:51 +000096- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
97 these systems, the mbstowcs() function is slightly buggy and must be
98 replaced with strlen() for the purpose of counting of number of wide
99 characters needed to represent the multi-byte character string.
100
Antoine Pitrou658fad82008-09-03 18:34:34 +0000101- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"

113 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
114 was correctly parsed but parsing of subsequent arguments failed.
115
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +0000116- Issue #3611: An exception __context__ could be cleared in a complex pattern

Antoine Pitrouec569b72008-08-26 22:40:48 +0000119- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
120 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
121 mechanism. In the process, fix a bug where isinstance() and issubclass(),
122 when given a tuple of classes as second argument, were looking up
123 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
124 type object.
125
Antoine Pitroue2dffc02008-08-26 22:02:58 +0000126- Issue #3663: Py_None was decref'd when printing SyntaxErrors.

Guilherme Polob212b752008-09-04 11:21:31 +0000178- Issue #1658: tkinter changes dict size during iteration in both
179 tkinter.BaseWidget and tkinter.scrolledtext.ScrolledText.
180
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000181- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000182 It is now maintained outside of the standard library at
183 http://www.jcea.es/programacion/pybsddb.htm.
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000184
Facundo Batistac469d4c2008-09-03 22:49:01 +0000185- Issue 600362: Relocated parse_qs() and parse_qsl(), from the cgi module

204
Amaury Forgeot d'Arcd8976f12008-09-02 23:22:56 +0000205- Issue #2975: When compiling several extension modules with Visual Studio 2008
206 from the same python interpreter, some environment variables would grow
207 without limit.
208
Benjamin Peterson6784eb72008-08-23 20:32:27 +0000209- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
210 exploitation of poor argument checking.
211
Jesus Cea6ba33292008-08-31 14:12:11 +0000212- bsddb code updated to version 4.7.3pre2. This code is the same than
213 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
214 The Python code is automatically translated using "2to3". Please, do not
215 update this code in Python 3.0 by hand. Update the 2.6 one and then
216 do "2to3".
217
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000218- The _bytesio and _stringio modules are now compiled into the python binary.
219
Gregory P. Smith693fc462008-09-06 20:13:06 +0000220- Issue #3492 and #3790: Fixed the zlib module and zipimport module uses of

Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000247Core and Builtins
248-----------------
249
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000250- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
251 arguments.
252
Antoine Pitrou616d2852008-08-19 22:09:34 +0000253- Issue #2394: implement more of the memoryview API, with the caveat that
254 only one-dimensional contiguous buffers are supported and exercised right
255 now. Slicing, slice assignment and comparison (equality and inequality)
256 have been added. Also, the tolist() method has been implemented, but only
257 for byte buffers. Endly, the API has been updated to return bytes objects
258 wherever it used to return bytearrays.
259
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000260- Issue #3560: clean up the new C PyMemoryView API so that naming is
261 internally consistent; add macros PyMemoryView_GET_BASE() and
262 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
263 without relying on a particular implementation; remove the ill-named
264 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
265
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000266- ctypes function pointers that are COM methods have a boolean True
267 value again.
268
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000269- Issue #1819: function calls with several named parameters are now on
270 average 35% faster (as measured by pybench).
271
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000272- The undocumented C APIs PyUnicode_AsString() and
273 PyUnicode_AsStringAndSize() were made private to the interpreter, in
274 order to be able to refine their interfaces for Python 3.1.
275
276 If you need to access the UTF-8 representation of a Unicode object
277 as bytes string, please use PyUnicode_AsUTF8String() instead.
278
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000279- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
280 to Python 3.0's stricter semantics which allow to avoid successive
281 reallocations of the result string (this also affects str.join()).

285-------
286
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000287- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
288 a build problem on MacOS with CJK locales. It adds four temporary
289 mappings to existing legacy codecs that are virtually compatible
290 with Mac encodings. They will be replaced by codecs correctly
291 implemented in 3.1.
292
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000293- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
294 "global name 'header' is not defined".
295
Antoine Pitroufd036452008-08-19 17:56:33 +0000296- Issue #2834: update the regular expression library to match the unicode
297 standards of py3k. In other words, mixing bytes and unicode strings
298 (be it as pattern, search string or replacement string) raises a TypeError.
299 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
300 and can be disabled by specifying a new re.ASCII flag; as for bytes
301 patterns, ASCII matching is the only option and trying to specify re.UNICODE
302 for such patterns raises a ValueError.
303
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000304- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
305 Code contributed by Matt Giuca. quote() now encodes the input
306 before quoting, unquote() decodes after unquoting. There are
307 new arguments to change the encoding and errors settings.
308 There are also new APIs to skip the encode/decode steps.
309 [un]quote_plus() are also affected.
310
Nick Coghlan36f49522008-08-18 12:31:52 +0000311- Issue #2235: numbers.Number now blocks inheritance of the default id()
312 based hash because that hash mechanism is not correct for numeric types.
313 All concrete numeric types that inherit from Number (rather than just
314 registering with it) must explicitly provide a hash implementation in
315 order for their instances to be hashable.
316
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000317- Issue #2676: in the email package, content-type parsing was hanging on
318 pathological input because of quadratic or exponential behaviour of a
319 regular expression.
320
Antoine Pitrou87695762008-08-14 22:44:29 +0000321- Issue #3476: binary buffered reading through the new "io" library is now
322 thread-safe.
323
Robert Schuppenies3d1c7de2008-08-10 11:28:17 +0000324- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
325 menu entries were not deleted.
326

638 'type' - whether they are builtin types or not.

Martin v. Löwis790465f2008-04-05 20:41:37 +0000640- The command line processing was converted to pass Unicode strings
641 through as unmodified as possible; as a consequence, the C API
642 related to command line arguments was changed to use wchar_t.
643
Georg Brandl52b92cc2008-05-25 09:43:03 +0000644- All backslashes in raw strings are interpreted literally. This

Guido van Rossumf4169812008-03-17 22:56:06 +0000705- A new pickle protocol (protocol 3) is added with explicit support
706 for bytes. This is the default protocol. It intentionally cannot
707 be unpickled by Python 2.x.
708
709- When a pickle written by Python 2.x contains an (8-bit) str
710 instance, this is now decoded to a (Unicode) str instance. The
711 encoding used to do this defaults to ASCII, but can be overridden
712 via two new keyword arguments to the Unpickler class. Previously
713 this would create bytes instances, which is usually wrong: str
714 instances are often used to pickle attribute names etc., and text is
715 more common than binary data anyway.

Martin v. Löwis071ef772008-03-08 11:24:24 +0000717- Default to ASCII as the locale.getpreferredencoding, if the POSIX

725 has been renamed tokenize and now works with bytes rather than
726 strings. A new detect_encoding function has been added for
727 determining source file encoding according to PEP-0263. Token
728 sequences returned by tokenize always start with an ENCODING token
729 which specifies the encoding used to decode the file. This token is
730 used to encode the output of untokenize back to bytes.

Fred Drake0e474a82007-10-11 18:01:43 +0000891
Guido van Rossum99533a92007-12-06 05:07:41 +0000892*Release date: 07-Dec-2007*
893
894(Note: this list is incomplete.)
Fred Drake0e474a82007-10-11 18:01:43 +0000895
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000896Core and Builtins
897-----------------
898
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000899- str8 now has the same construction signature as bytes.
900
Georg Brandl52b92cc2008-05-25 09:43:03 +0000901- Comparisons between str and str8 now return False/True for ==/!=.
902 sqlite3 returns str8 when recreating on object from it's __conform__
903 value. The struct module returns str8 for all string-related
904 formats. This was true before this change, but becomes more
905 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000906
Georg Brandl52b92cc2008-05-25 09:43:03 +0000907- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
908 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000909
910- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
911
912- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000913 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000914 `PyUnicode_DecodeFSDefault(char*)` was added.
915
Georg Brandl52b92cc2008-05-25 09:43:03 +0000916- io.open() and _fileio.FileIO have grown a new argument closefd. A
917 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000918
Georg Brandl52b92cc2008-05-25 09:43:03 +0000919- Added a new option -b to issues warnings (-bb for errors) about
920 certain operations between bytes/buffer and str like str(b'') and
921 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000922
Georg Brandl52b92cc2008-05-25 09:43:03 +0000923- The standards streams sys.stdin, stdout and stderr may be None when
924 the when the C runtime library returns an invalid file descriptor
925 for the streams (fileno(stdin) < 0). For now this happens only for
926 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000927
Christian Heimesbce52be2007-11-17 19:08:41 +0000928- Added PCbuild9 directory for VS 2008.
929
Georg Brandl52b92cc2008-05-25 09:43:03 +0000930- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
931 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000932
Georg Brandl52b92cc2008-05-25 09:43:03 +0000933- Unbound methods are gone for good. ClassObject.method returns an
934 ordinary function object, instance.method still returns a bound
935 method object. The API of bound methods is cleaned up, too. The
936 im_class attribute is removed and im_func + im_self are renamed to
937 __func__ and __self__. The factory PyMethod_New takes only func and
938 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000939
Georg Brandl52b92cc2008-05-25 09:43:03 +0000940- intobject.h is no longer included by Python.h. The remains were
941 moved to longobject.h. It still exists to define several aliases
942 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000943
Christian Heimesa37d4c62007-12-04 23:02:19 +0000944- Removed sys.maxint, use sys.maxsize instead.
945
Fred Drake0e474a82007-10-11 18:01:43 +0000946Extension Modules
947-----------------
948
949- The `hotshot` profiler has been removed; use `cProfile` instead.
950
Brett Cannone9fd2312007-10-12 19:18:19 +0000951Library
952-------
953
Georg Brandl52b92cc2008-05-25 09:43:03 +0000954- When loading an external file using testfile(), the passed-in
955 encoding argument was being ignored if __loader__ is defined and
956 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000957
Georg Brandl52b92cc2008-05-25 09:43:03 +0000958- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
959 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000960
Christian Heimesc9543e42007-11-28 08:28:28 +0000961- Removed the 'new' module.
962
Georg Brandl52b92cc2008-05-25 09:43:03 +0000963- Removed all types from the 'types' module that are easily accessable
964 through builtins.
Brett Cannone9fd2312007-10-12 19:18:19 +0000965
Georg Brandl52d168a2008-01-07 18:10:24 +0000966
Guido van Rossum4405cf32007-08-30 17:16:55 +0000967What's New in Python 3.0a1?
Guido van Rossum45aecf42006-03-15 04:58:47 +0000968==========================
Thomas Wouters4d70c3d2006-06-08 14:42:34 +0000969
Guido van Rossum4405cf32007-08-30 17:16:55 +0000970*Release date: 31-Aug-2007*
Neal Norwitz4886cc32006-08-21 17:06:07 +0000971
972Core and Builtins
973-----------------
974
Martin v. Löwis47383402007-08-15 07:32:56 +0000975- PEP 3131: Support non-ASCII identifiers.
976
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000977- PEP 3120: Change default encoding to UTF-8.
978
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000979- PEP 3123: Use proper C inheritance for PyObject.
980
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000981- Removed the __oct__ and __hex__ special methods and added a bin()
982 builtin function.
983
Georg Brandl52b92cc2008-05-25 09:43:03 +0000984- PEP 3127: octal literals now start with "0o". Old-style octal
985 literals are invalid. There are binary literals with a prefix of
986 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000987
Guido van Rossume7ba4952007-06-06 23:52:48 +0000988- None, True, False are now keywords.
989
Guido van Rossum29478ef2007-05-29 00:39:44 +0000990- PEP 3119: isinstance() and issubclass() can be overridden.
991
Guido van Rossumebe3e162007-05-17 18:20:34 +0000992- Remove BaseException.message.
993
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000994- Remove tuple parameter unpacking (PEP 3113).
995
Georg Brandl52b92cc2008-05-25 09:43:03 +0000996- Remove the f_restricted attribute from frames. This naturally leads
997 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000998
Georg Brandl52b92cc2008-05-25 09:43:03 +0000999- PEP 3132 was accepted. That means that you can do ``a, *b =
1000 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +00001001
Georg Brandl52b92cc2008-05-25 09:43:03 +00001002- range() now returns an iterator rather than a list. Floats are not
1003 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +00001004
Nick Coghlan650f0d02007-04-15 12:05:43 +00001005- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +00001006 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +00001007
Guido van Rossume27dc722007-03-27 22:37:34 +00001008- By default, != returns the opposite of ==, unless the latter returns
1009 NotImplemented.
1010
Georg Brandl52b92cc2008-05-25 09:43:03 +00001011- Patch #1680961: sys.exitfunc has been removed and replaced with a
1012 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +00001013
Georg Brandl801dd732007-03-18 20:18:31 +00001014- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +00001015 keyword arg in the class statement, which can now use the full
1016 syntax of a parameter list. Also, the metaclass can implement a
1017 __prepare__ function which will be called to create the dictionary
1018 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +00001019
Georg Brandl428f0642007-03-18 18:35:15 +00001020- The long-deprecated argument "pend" of PyFloat_FromString() has been
1021 removed.
1022
Georg Brandle32b4222007-03-10 22:13:27 +00001023- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +00001024 its argument, if it exists. If not, it will work like before. This
1025 allows customizing the output of dir() in the presence of a
1026 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +00001027
Neal Norwitz8dfc4a92007-08-11 06:39:53 +00001028- Removed support for __members__ and __methods__.
1029
Georg Brandle32b4222007-03-10 22:13:27 +00001030- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +00001031
Georg Brandle32b4222007-03-10 22:13:27 +00001032- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001033 functionality formerly known as raw_input(); the name raw_input() is
1034 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +00001035
Georg Brandl52b92cc2008-05-25 09:43:03 +00001036- Classes listed in an 'except' clause must inherit from
1037 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001038
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001039- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001040 and .keys(), .items(), .values() return dict views, which behave
1041 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001042
Guido van Rossum8b545362007-02-09 23:52:14 +00001043- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001044 'softspace' attribute of files is now gone (since print() doesn't
1045 use it). A side effect of this change is that you can get
1046 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001047
1048 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001049 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001050
1051 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001052
Brett Cannon398db8b2007-01-29 23:44:37 +00001053- PEP 3102: keyword-only arguments.
1054
Georg Brandl52b92cc2008-05-25 09:43:03 +00001055- Int/Long unification is complete. The 'long' built-in type and
1056 literals with trailing 'L' or 'l' have been removed. Performance
1057 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001058
1059- 'except E, V' must now be spelled as 'except E as V' and deletes V
1060 at the end of the except clause; V must be a simple name.
1061
Neal Norwitzc1505362006-12-28 06:47:50 +00001062- Added function annotations per PEP 3107.
1063
Georg Brandl52b92cc2008-05-25 09:43:03 +00001064- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001065
1066 >>> def f(x):
1067 ... def inc():
1068 ... nonlocal x
1069 ... x += 1
1070 ... return x
1071 ... return inc
1072 ...
1073 >>> inc = f(0)
1074 >>> inc()
1075 1
1076 >>> inc()
1077 2
1078
Georg Brandl66a796e2006-12-19 20:50:34 +00001079- Moved intern() to sys.intern().
1080
1081- exec is now a function.
1082
1083- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001084
Neal Norwitz4886cc32006-08-21 17:06:07 +00001085- Classic classes are a thing of the past. All classes are new style.
1086
1087- Exceptions *must* derive from BaseException.
1088
1089- Integer division always returns a float. The -Q option is no more.
1090 All the following are gone:
1091 * PyNumber_Divide and PyNumber_InPlaceDivide
1092 * __div__, __rdiv__, and __idiv__
1093 * nb_divide, nb_inplace_divide
1094 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1095 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1096 if we want to re-use __div__ and friends. If we do, it will make
1097 it harder to write code for both 2.x and 3.x.)
1098
1099- 'as' and 'with' are keywords.
1100
1101- Absolute import is the default behavior for 'import foo' etc.
1102
Georg Brandl52b92cc2008-05-25 09:43:03 +00001103- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001104
Georg Brandl52b92cc2008-05-25 09:43:03 +00001105- Removed these Python builtins: apply(), callable(), coerce(),
1106 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001107
Georg Brandl52b92cc2008-05-25 09:43:03 +00001108- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001109
Georg Brandl52b92cc2008-05-25 09:43:03 +00001110- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001111
1112- Remove C API support for restricted execution.
1113
Guido van Rossumcf1be882007-08-30 22:07:17 +00001114- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001115 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001116 sequences of unequal length -- it now stops after the shortest one
1117 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001118
Georg Brandl52b92cc2008-05-25 09:43:03 +00001119- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001120
1121- Added class decorators per PEP 3129.
1122

1124Extension Modules
1125-----------------
1126
Georg Brandl52b92cc2008-05-25 09:43:03 +00001127- Removed the imageop module. Obsolete long with its unit tests
1128 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +00001129
Georg Brandl52b92cc2008-05-25 09:43:03 +00001130- Removed these attributes from the operator module: div, idiv,
1131 __div__, __idiv__, isCallable, sequenceIncludes.
1132
1133- Removed these attributes from the sys module: exc_clear(), exc_type,
1134 exc_value, exc_traceback.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001135

1137Library
1138-------
1139
Georg Brandl52b92cc2008-05-25 09:43:03 +00001140- Removed the compiler package. Use of the _ast module and (an
1141 eventual) AST -> bytecode mechanism.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001142
Georg Brandl52b92cc2008-05-25 09:43:03 +00001143- Removed these modules: audiodev, Bastion, bsddb185, exceptions,
1144 linuxaudiodev, md5, MimeWriter, mimify, popen2, rexec, sets, sha,
1145 stringold, strop, sunaudiodev, timing, xmllib.
Guido van Rossum33d26892007-08-05 15:29:28 +00001146
Georg Brandl52b92cc2008-05-25 09:43:03 +00001147- Moved the toaiff module to Tools/Demos.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001148
Georg Brandl52b92cc2008-05-25 09:43:03 +00001149- Removed obsolete IRIX modules: al/AL, cd/CD, cddb, cdplayer, cl/CL,
1150 DEVICE, ERRNO, FILE, fl/FL, flp, fm, GET, gl/GL, GLWS, IN, imgfile,
1151 IOCTL, jpeg, panel, panelparser, readcd, sgi, sv/SV, torgb, WAIT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001152
Georg Brandl52b92cc2008-05-25 09:43:03 +00001153- Removed obsolete functions: commands.getstatus(), os.popen*().
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001154
Georg Brandl52b92cc2008-05-25 09:43:03 +00001155- Removed functions in the string module that are also string methods;
Martin v. Löwis967f1e32007-08-14 09:23:10 +00001156 Remove string.{letters, lowercase, uppercase}.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001157
