Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +000071 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
72 although under Windows it fails at a later point.
Antoine Pitrou5651eaa2008-09-06 20:46:58 +000073
Benjamin Peterson791dc2f2008-09-05 23:27:15 +000074- Issue #3279: Importing site at interpreter was failing silently because the
75 site module uses the open builtin which was not initialized at the time.

Amaury Forgeot d'Arc1b933ed2008-09-04 22:34:09 +000081 error conditions.
82
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000083- Issue #3594: Fix Parser/tokenizer.c:fp_setreadl() to open the file being
Brett Cannon8a9583e2008-09-04 05:04:25 +000084 tokenized by either a file path or file pointer for the benefit of
85 PyTokenizer_FindEncoding().
86
Antoine Pitroufff95302008-09-03 18:58:51 +000087- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
88 these systems, the mbstowcs() function is slightly buggy and must be
89 replaced with strlen() for the purpose of counting of number of wide
90 characters needed to represent the multi-byte character string.
91
Antoine Pitrou658fad82008-09-03 18:34:34 +000092- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"

95 limit when USE_STACKCHEK was enabled.
96
Brett Cannon54bd41d2008-09-02 04:01:42 +000097- Issue 3639: The _warnings module could segfault the interpreter when

104 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
105 was correctly parsed but parsing of subsequent arguments failed.
106
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +0000107- Issue #3611: An exception __context__ could be cleared in a complex pattern
108 involving a __del__ method re-raising an exception.

Antoine Pitrouec569b72008-08-26 22:40:48 +0000110- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
111 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
112 mechanism. In the process, fix a bug where isinstance() and issubclass(),
113 when given a tuple of classes as second argument, were looking up
114 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
115 type object.
116
Antoine Pitroue2dffc02008-08-26 22:02:58 +0000117- Issue #3663: Py_None was decref'd when printing SyntaxErrors.

Guilherme Polob212b752008-09-04 11:21:31 +0000169- Issue #1658: tkinter changes dict size during iteration in both
170 tkinter.BaseWidget and tkinter.scrolledtext.ScrolledText.
171
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000172- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000173 It is now maintained outside of the standard library at

202
Jesus Cea6ba33292008-08-31 14:12:11 +0000203- bsddb code updated to version 4.7.3pre2. This code is the same than
204 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
205 The Python code is automatically translated using "2to3". Please, do not
206 update this code in Python 3.0 by hand. Update the 2.6 one and then
207 do "2to3".
208
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000209- The _bytesio and _stringio modules are now compiled into the python binary.

Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000238Core and Builtins
239-----------------
240
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000241- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
242 arguments.
243
Antoine Pitrou616d2852008-08-19 22:09:34 +0000244- Issue #2394: implement more of the memoryview API, with the caveat that
245 only one-dimensional contiguous buffers are supported and exercised right
246 now. Slicing, slice assignment and comparison (equality and inequality)
247 have been added. Also, the tolist() method has been implemented, but only
248 for byte buffers. Endly, the API has been updated to return bytes objects
249 wherever it used to return bytearrays.
250
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000251- Issue #3560: clean up the new C PyMemoryView API so that naming is
252 internally consistent; add macros PyMemoryView_GET_BASE() and
253 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
254 without relying on a particular implementation; remove the ill-named
255 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
256
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000257- ctypes function pointers that are COM methods have a boolean True
258 value again.
259
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000260- Issue #1819: function calls with several named parameters are now on
261 average 35% faster (as measured by pybench).
262
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000263- The undocumented C APIs PyUnicode_AsString() and
264 PyUnicode_AsStringAndSize() were made private to the interpreter, in
265 order to be able to refine their interfaces for Python 3.1.
266
267 If you need to access the UTF-8 representation of a Unicode object
268 as bytes string, please use PyUnicode_AsUTF8String() instead.
269
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000270- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
271 to Python 3.0's stricter semantics which allow to avoid successive
272 reallocations of the result string (this also affects str.join()).

276-------
277
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000278- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
279 a build problem on MacOS with CJK locales. It adds four temporary
280 mappings to existing legacy codecs that are virtually compatible
281 with Mac encodings. They will be replaced by codecs correctly
282 implemented in 3.1.
283
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000284- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
285 "global name 'header' is not defined".
286
Antoine Pitroufd036452008-08-19 17:56:33 +0000287- Issue #2834: update the regular expression library to match the unicode
288 standards of py3k. In other words, mixing bytes and unicode strings
289 (be it as pattern, search string or replacement string) raises a TypeError.
290 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
291 and can be disabled by specifying a new re.ASCII flag; as for bytes
292 patterns, ASCII matching is the only option and trying to specify re.UNICODE
293 for such patterns raises a ValueError.
294
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000295- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
296 Code contributed by Matt Giuca. quote() now encodes the input
297 before quoting, unquote() decodes after unquoting. There are
298 new arguments to change the encoding and errors settings.
299 There are also new APIs to skip the encode/decode steps.
300 [un]quote_plus() are also affected.
301
Nick Coghlan36f49522008-08-18 12:31:52 +0000302- Issue #2235: numbers.Number now blocks inheritance of the default id()
303 based hash because that hash mechanism is not correct for numeric types.
304 All concrete numeric types that inherit from Number (rather than just
305 registering with it) must explicitly provide a hash implementation in
306 order for their instances to be hashable.
307
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000308- Issue #2676: in the email package, content-type parsing was hanging on
309 pathological input because of quadratic or exponential behaviour of a
310 regular expression.
311
Antoine Pitrou87695762008-08-14 22:44:29 +0000312- Issue #3476: binary buffered reading through the new "io" library is now
313 thread-safe.
314
Robert Schuppenies3d1c7de2008-08-10 11:28:17 +0000315- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
316 menu entries were not deleted.
317
Lars Gustäbel0c24e8b2008-08-02 11:43:24 +0000318- Remove the TarFileCompat class from tarfile.py.
319
Amaury Forgeot d'Arcbdbddf82008-08-01 00:06:49 +0000320- Issue #2491: os.fdopen is now almost an alias for the built-in open(), and
321 accepts the same parameters. It just checks that its first argument is an
322 integer.
323
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000324- Issue #3394: zipfile.writestr sets external attributes when passed a
325 file name rather than a ZipInfo instance, so files are extracted with

Guido van Rossumf4169812008-03-17 22:56:06 +0000696- A new pickle protocol (protocol 3) is added with explicit support
697 for bytes. This is the default protocol. It intentionally cannot
698 be unpickled by Python 2.x.
699
700- When a pickle written by Python 2.x contains an (8-bit) str
701 instance, this is now decoded to a (Unicode) str instance. The
702 encoding used to do this defaults to ASCII, but can be overridden
703 via two new keyword arguments to the Unpickler class. Previously
704 this would create bytes instances, which is usually wrong: str
705 instances are often used to pickle attribute names etc., and text is
706 more common than binary data anyway.

Martin v. Löwis071ef772008-03-08 11:24:24 +0000708- Default to ASCII as the locale.getpreferredencoding, if the POSIX

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

Georg Brandl52b92cc2008-05-25 09:43:03 +0000892- Comparisons between str and str8 now return False/True for ==/!=.
893 sqlite3 returns str8 when recreating on object from it's __conform__
894 value. The struct module returns str8 for all string-related
895 formats. This was true before this change, but becomes more
896 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000897
Georg Brandl52b92cc2008-05-25 09:43:03 +0000898- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
899 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000900
901- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
902
903- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000904 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000905 `PyUnicode_DecodeFSDefault(char*)` was added.
906
Georg Brandl52b92cc2008-05-25 09:43:03 +0000907- io.open() and _fileio.FileIO have grown a new argument closefd. A
908 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000909
Georg Brandl52b92cc2008-05-25 09:43:03 +0000910- Added a new option -b to issues warnings (-bb for errors) about
911 certain operations between bytes/buffer and str like str(b'') and
912 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000913
Georg Brandl52b92cc2008-05-25 09:43:03 +0000914- The standards streams sys.stdin, stdout and stderr may be None when
915 the when the C runtime library returns an invalid file descriptor
916 for the streams (fileno(stdin) < 0). For now this happens only for
917 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000918
Christian Heimesbce52be2007-11-17 19:08:41 +0000919- Added PCbuild9 directory for VS 2008.
920
Georg Brandl52b92cc2008-05-25 09:43:03 +0000921- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
922 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000923
Georg Brandl52b92cc2008-05-25 09:43:03 +0000924- Unbound methods are gone for good. ClassObject.method returns an
925 ordinary function object, instance.method still returns a bound
926 method object. The API of bound methods is cleaned up, too. The
927 im_class attribute is removed and im_func + im_self are renamed to
928 __func__ and __self__. The factory PyMethod_New takes only func and
929 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000930
Georg Brandl52b92cc2008-05-25 09:43:03 +0000931- intobject.h is no longer included by Python.h. The remains were
932 moved to longobject.h. It still exists to define several aliases
933 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000934
Christian Heimesa37d4c62007-12-04 23:02:19 +0000935- Removed sys.maxint, use sys.maxsize instead.

943-------
944
Georg Brandl52b92cc2008-05-25 09:43:03 +0000945- When loading an external file using testfile(), the passed-in
946 encoding argument was being ignored if __loader__ is defined and
947 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000948
Georg Brandl52b92cc2008-05-25 09:43:03 +0000949- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
950 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000951
Christian Heimesc9543e42007-11-28 08:28:28 +0000952- Removed the 'new' module.
953
Georg Brandl52b92cc2008-05-25 09:43:03 +0000954- Removed all types from the 'types' module that are easily accessable
955 through builtins.

Neal Norwitz4886cc32006-08-21 17:06:07 +0000962
963Core and Builtins
964-----------------
965
Martin v. Löwis47383402007-08-15 07:32:56 +0000966- PEP 3131: Support non-ASCII identifiers.
967
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000968- PEP 3120: Change default encoding to UTF-8.
969
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000970- PEP 3123: Use proper C inheritance for PyObject.
971
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000972- Removed the __oct__ and __hex__ special methods and added a bin()
973 builtin function.
974
Georg Brandl52b92cc2008-05-25 09:43:03 +0000975- PEP 3127: octal literals now start with "0o". Old-style octal
976 literals are invalid. There are binary literals with a prefix of
977 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000978
Guido van Rossume7ba4952007-06-06 23:52:48 +0000979- None, True, False are now keywords.
980
Guido van Rossum29478ef2007-05-29 00:39:44 +0000981- PEP 3119: isinstance() and issubclass() can be overridden.
982
Guido van Rossumebe3e162007-05-17 18:20:34 +0000983- Remove BaseException.message.
984
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000985- Remove tuple parameter unpacking (PEP 3113).
986
Georg Brandl52b92cc2008-05-25 09:43:03 +0000987- Remove the f_restricted attribute from frames. This naturally leads
988 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000989
Georg Brandl52b92cc2008-05-25 09:43:03 +0000990- PEP 3132 was accepted. That means that you can do ``a, *b =
991 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000992
Georg Brandl52b92cc2008-05-25 09:43:03 +0000993- range() now returns an iterator rather than a list. Floats are not
994 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000995
Nick Coghlan650f0d02007-04-15 12:05:43 +0000996- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000997 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000998
Guido van Rossume27dc722007-03-27 22:37:34 +0000999- By default, != returns the opposite of ==, unless the latter returns
1000 NotImplemented.
1001
Georg Brandl52b92cc2008-05-25 09:43:03 +00001002- Patch #1680961: sys.exitfunc has been removed and replaced with a
1003 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +00001004
Georg Brandl801dd732007-03-18 20:18:31 +00001005- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +00001006 keyword arg in the class statement, which can now use the full
1007 syntax of a parameter list. Also, the metaclass can implement a
1008 __prepare__ function which will be called to create the dictionary
1009 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +00001010
Georg Brandl428f0642007-03-18 18:35:15 +00001011- The long-deprecated argument "pend" of PyFloat_FromString() has been
1012 removed.
1013
Georg Brandle32b4222007-03-10 22:13:27 +00001014- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +00001015 its argument, if it exists. If not, it will work like before. This
1016 allows customizing the output of dir() in the presence of a
1017 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +00001018
Neal Norwitz8dfc4a92007-08-11 06:39:53 +00001019- Removed support for __members__ and __methods__.
1020
Georg Brandle32b4222007-03-10 22:13:27 +00001021- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +00001022
Georg Brandle32b4222007-03-10 22:13:27 +00001023- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001024 functionality formerly known as raw_input(); the name raw_input() is
1025 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +00001026
Georg Brandl52b92cc2008-05-25 09:43:03 +00001027- Classes listed in an 'except' clause must inherit from
1028 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001029
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001030- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001031 and .keys(), .items(), .values() return dict views, which behave
1032 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001033
Guido van Rossum8b545362007-02-09 23:52:14 +00001034- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001035 'softspace' attribute of files is now gone (since print() doesn't
1036 use it). A side effect of this change is that you can get
1037 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001038
1039 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001040 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001041
1042 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001043
Brett Cannon398db8b2007-01-29 23:44:37 +00001044- PEP 3102: keyword-only arguments.
1045
Georg Brandl52b92cc2008-05-25 09:43:03 +00001046- Int/Long unification is complete. The 'long' built-in type and
1047 literals with trailing 'L' or 'l' have been removed. Performance
1048 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001049
1050- 'except E, V' must now be spelled as 'except E as V' and deletes V
1051 at the end of the except clause; V must be a simple name.
1052
Neal Norwitzc1505362006-12-28 06:47:50 +00001053- Added function annotations per PEP 3107.
1054
Georg Brandl52b92cc2008-05-25 09:43:03 +00001055- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001056
1057 >>> def f(x):
1058 ... def inc():
1059 ... nonlocal x
1060 ... x += 1
1061 ... return x
1062 ... return inc
1063 ...
1064 >>> inc = f(0)
1065 >>> inc()
1066 1
1067 >>> inc()
1068 2
1069
Georg Brandl66a796e2006-12-19 20:50:34 +00001070- Moved intern() to sys.intern().
1071
1072- exec is now a function.
1073
1074- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001075
Neal Norwitz4886cc32006-08-21 17:06:07 +00001076- Classic classes are a thing of the past. All classes are new style.
1077
1078- Exceptions *must* derive from BaseException.
1079
1080- Integer division always returns a float. The -Q option is no more.
1081 All the following are gone:
1082 * PyNumber_Divide and PyNumber_InPlaceDivide
1083 * __div__, __rdiv__, and __idiv__
1084 * nb_divide, nb_inplace_divide
1085 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1086 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1087 if we want to re-use __div__ and friends. If we do, it will make
1088 it harder to write code for both 2.x and 3.x.)
1089
1090- 'as' and 'with' are keywords.
1091
1092- Absolute import is the default behavior for 'import foo' etc.
1093
Georg Brandl52b92cc2008-05-25 09:43:03 +00001094- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001095
Georg Brandl52b92cc2008-05-25 09:43:03 +00001096- Removed these Python builtins: apply(), callable(), coerce(),
1097 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001098
Georg Brandl52b92cc2008-05-25 09:43:03 +00001099- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001100
Georg Brandl52b92cc2008-05-25 09:43:03 +00001101- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001102
1103- Remove C API support for restricted execution.
1104
Guido van Rossumcf1be882007-08-30 22:07:17 +00001105- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001106 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001107 sequences of unequal length -- it now stops after the shortest one
1108 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001109
Georg Brandl52b92cc2008-05-25 09:43:03 +00001110- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001111
1112- Added class decorators per PEP 3129.

1115Extension Modules
1116-----------------
1117
Georg Brandl52b92cc2008-05-25 09:43:03 +00001118- Removed the imageop module. Obsolete long with its unit tests
1119 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +00001120
Georg Brandl52b92cc2008-05-25 09:43:03 +00001121- Removed these attributes from the operator module: div, idiv,
1122 __div__, __idiv__, isCallable, sequenceIncludes.
1123
1124- Removed these attributes from the sys module: exc_clear(), exc_type,
1125 exc_value, exc_traceback.

1129-------
1130
Georg Brandl52b92cc2008-05-25 09:43:03 +00001131- Removed the compiler package. Use of the _ast module and (an
1132 eventual) AST -> bytecode mechanism.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001133
Georg Brandl52b92cc2008-05-25 09:43:03 +00001134- Removed these modules: audiodev, Bastion, bsddb185, exceptions,
1135 linuxaudiodev, md5, MimeWriter, mimify, popen2, rexec, sets, sha,
1136 stringold, strop, sunaudiodev, timing, xmllib.

Georg Brandl52b92cc2008-05-25 09:43:03 +00001138- Moved the toaiff module to Tools/Demos.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001139
Georg Brandl52b92cc2008-05-25 09:43:03 +00001140- Removed obsolete IRIX modules: al/AL, cd/CD, cddb, cdplayer, cl/CL,

Georg Brandl52b92cc2008-05-25 09:43:03 +00001144- Removed obsolete functions: commands.getstatus(), os.popen*().
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001145
Georg Brandl52b92cc2008-05-25 09:43:03 +00001146- Removed functions in the string module that are also string methods;
Martin v. Löwis967f1e32007-08-14 09:23:10 +00001147 Remove string.{letters, lowercase, uppercase}.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001148
Georg Brandl52b92cc2008-05-25 09:43:03 +00001149- Removed support for long obsolete platforms: plat-aix3, plat-irix5.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001150
Georg Brandl52b92cc2008-05-25 09:43:03 +00001151- Removed xmlrpclib.SlowParser. It was based on xmllib.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001152
