Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +0000100 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
101 although under Windows it fails at a later point.
Antoine Pitrou5651eaa2008-09-06 20:46:58 +0000102
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000103- Issue #3279: Importing site at interpreter was failing silently because the
104 site module uses the open builtin which was not initialized at the time.
105
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +0000106- Issue #3660: Corrected a reference leak in str.encode() when the encoder

Brett Cannon8a9583e2008-09-04 05:04:25 +0000113 tokenized by either a file path or file pointer for the benefit of
114 PyTokenizer_FindEncoding().
115
Antoine Pitroufff95302008-09-03 18:58:51 +0000116- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
117 these systems, the mbstowcs() function is slightly buggy and must be
118 replaced with strlen() for the purpose of counting of number of wide
119 characters needed to represent the multi-byte character string.
120
Antoine Pitrou658fad82008-09-03 18:34:34 +0000121- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"

134 was correctly parsed but parsing of subsequent arguments failed.
135
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +0000136- Issue #3611: An exception __context__ could be cleared in a complex pattern

140 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
141 mechanism. In the process, fix a bug where isinstance() and issubclass(),
142 when given a tuple of classes as second argument, were looking up
143 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
144 type object.
145

200
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000201- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000202 It is now maintained outside of the standard library at

233 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
234 The Python code is automatically translated using "2to3". Please, do not
235 update this code in Python 3.0 by hand. Update the 2.6 one and then
236 do "2to3".

Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000267Core and Builtins
268-----------------
269
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000270- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
271 arguments.
272
Antoine Pitrou616d2852008-08-19 22:09:34 +0000273- Issue #2394: implement more of the memoryview API, with the caveat that
274 only one-dimensional contiguous buffers are supported and exercised right
275 now. Slicing, slice assignment and comparison (equality and inequality)
276 have been added. Also, the tolist() method has been implemented, but only
277 for byte buffers. Endly, the API has been updated to return bytes objects
278 wherever it used to return bytearrays.
279
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000280- Issue #3560: clean up the new C PyMemoryView API so that naming is
281 internally consistent; add macros PyMemoryView_GET_BASE() and
282 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
283 without relying on a particular implementation; remove the ill-named
284 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
285
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000286- ctypes function pointers that are COM methods have a boolean True
287 value again.
288
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000289- Issue #1819: function calls with several named parameters are now on
290 average 35% faster (as measured by pybench).
291
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000292- The undocumented C APIs PyUnicode_AsString() and
293 PyUnicode_AsStringAndSize() were made private to the interpreter, in
294 order to be able to refine their interfaces for Python 3.1.
295
296 If you need to access the UTF-8 representation of a Unicode object
297 as bytes string, please use PyUnicode_AsUTF8String() instead.
298
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000299- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
300 to Python 3.0's stricter semantics which allow to avoid successive
301 reallocations of the result string (this also affects str.join()).

306
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000307- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
308 a build problem on MacOS with CJK locales. It adds four temporary
309 mappings to existing legacy codecs that are virtually compatible
310 with Mac encodings. They will be replaced by codecs correctly
311 implemented in 3.1.
312
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000313- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
314 "global name 'header' is not defined".
315
Antoine Pitroufd036452008-08-19 17:56:33 +0000316- Issue #2834: update the regular expression library to match the unicode
317 standards of py3k. In other words, mixing bytes and unicode strings
318 (be it as pattern, search string or replacement string) raises a TypeError.
319 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
320 and can be disabled by specifying a new re.ASCII flag; as for bytes
321 patterns, ASCII matching is the only option and trying to specify re.UNICODE

Guido van Rossum52dbbb92008-08-18 21:44:30 +0000324- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
325 Code contributed by Matt Giuca. quote() now encodes the input
326 before quoting, unquote() decodes after unquoting. There are
327 new arguments to change the encoding and errors settings.
328 There are also new APIs to skip the encode/decode steps.
329 [un]quote_plus() are also affected.

Nick Coghlan36f49522008-08-18 12:31:52 +0000331- Issue #2235: numbers.Number now blocks inheritance of the default id()
332 based hash because that hash mechanism is not correct for numeric types.
333 All concrete numeric types that inherit from Number (rather than just
334 registering with it) must explicitly provide a hash implementation in
335 order for their instances to be hashable.
336
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000337- Issue #2676: in the email package, content-type parsing was hanging on

Amaury Forgeot d'Arcbdbddf82008-08-01 00:06:49 +0000349- Issue #2491: os.fdopen is now almost an alias for the built-in open(), and
350 accepts the same parameters. It just checks that its first argument is an
351 integer.
352
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000353- Issue #3394: zipfile.writestr sets external attributes when passed a
354 file name rather than a ZipInfo instance, so files are extracted with
355 mode 0600 rather than 000 under Unix.
356
Antoine Pitrouc66f9092008-07-28 19:46:11 +0000357- Issue #2523: Fix quadratic behaviour when read()ing a binary file without

Guido van Rossumf4169812008-03-17 22:56:06 +0000725- A new pickle protocol (protocol 3) is added with explicit support
726 for bytes. This is the default protocol. It intentionally cannot
727 be unpickled by Python 2.x.
728
729- When a pickle written by Python 2.x contains an (8-bit) str
730 instance, this is now decoded to a (Unicode) str instance. The
731 encoding used to do this defaults to ASCII, but can be overridden
732 via two new keyword arguments to the Unpickler class. Previously
733 this would create bytes instances, which is usually wrong: str
734 instances are often used to pickle attribute names etc., and text is
735 more common than binary data anyway.
736
Martin v. Löwis071ef772008-03-08 11:24:24 +0000737- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000738 system doesn't support CODESET and LANG isn't set or doesn't allow
739 deduction of an encoding.

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

893-----
894
Georg Brandl52b92cc2008-05-25 09:43:03 +0000895- Renamed --enable-unicode configure flag to --with-wide-unicode,
896 since Unicode strings can't be disabled anymore.

902 Py_TYPE and Py_REFCNT.
903
Georg Brandl52b92cc2008-05-25 09:43:03 +0000904- New API PyImport_ImportModuleNoBlock(), works like
905 PyImport_ImportModule() but won't block on the import lock
906 (returning an error instead).

Fred Drake0e474a82007-10-11 18:01:43 +0000909What's New in Python 3.0a2?
Christian Heimesbc873412007-12-08 22:11:32 +0000910===========================
Fred Drake0e474a82007-10-11 18:01:43 +0000911
Guido van Rossum99533a92007-12-06 05:07:41 +0000912*Release date: 07-Dec-2007*
913
914(Note: this list is incomplete.)
Fred Drake0e474a82007-10-11 18:01:43 +0000915
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000916Core and Builtins
917-----------------
918
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000919- str8 now has the same construction signature as bytes.
920
Georg Brandl52b92cc2008-05-25 09:43:03 +0000921- Comparisons between str and str8 now return False/True for ==/!=.
922 sqlite3 returns str8 when recreating on object from it's __conform__
923 value. The struct module returns str8 for all string-related
924 formats. This was true before this change, but becomes more
925 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000926
Georg Brandl52b92cc2008-05-25 09:43:03 +0000927- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
928 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000929
930- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
931
932- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000933 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000934 `PyUnicode_DecodeFSDefault(char*)` was added.
935
Georg Brandl52b92cc2008-05-25 09:43:03 +0000936- io.open() and _fileio.FileIO have grown a new argument closefd. A
937 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000938
Georg Brandl52b92cc2008-05-25 09:43:03 +0000939- Added a new option -b to issues warnings (-bb for errors) about
940 certain operations between bytes/buffer and str like str(b'') and
941 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000942
Georg Brandl52b92cc2008-05-25 09:43:03 +0000943- The standards streams sys.stdin, stdout and stderr may be None when
944 the when the C runtime library returns an invalid file descriptor
945 for the streams (fileno(stdin) < 0). For now this happens only for
946 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000947
Christian Heimesbce52be2007-11-17 19:08:41 +0000948- Added PCbuild9 directory for VS 2008.
949
Georg Brandl52b92cc2008-05-25 09:43:03 +0000950- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
951 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000952
Georg Brandl52b92cc2008-05-25 09:43:03 +0000953- Unbound methods are gone for good. ClassObject.method returns an
954 ordinary function object, instance.method still returns a bound
955 method object. The API of bound methods is cleaned up, too. The
956 im_class attribute is removed and im_func + im_self are renamed to
957 __func__ and __self__. The factory PyMethod_New takes only func and
958 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000959
Georg Brandl52b92cc2008-05-25 09:43:03 +0000960- intobject.h is no longer included by Python.h. The remains were
961 moved to longobject.h. It still exists to define several aliases
962 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000963
Christian Heimesa37d4c62007-12-04 23:02:19 +0000964- Removed sys.maxint, use sys.maxsize instead.
965
Fred Drake0e474a82007-10-11 18:01:43 +0000966Extension Modules
967-----------------
968
969- The `hotshot` profiler has been removed; use `cProfile` instead.
970
Brett Cannone9fd2312007-10-12 19:18:19 +0000971Library
972-------
973
Georg Brandl52b92cc2008-05-25 09:43:03 +0000974- When loading an external file using testfile(), the passed-in
975 encoding argument was being ignored if __loader__ is defined and
976 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000977
Georg Brandl52b92cc2008-05-25 09:43:03 +0000978- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
979 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000980
Christian Heimesc9543e42007-11-28 08:28:28 +0000981- Removed the 'new' module.
982
Georg Brandl52b92cc2008-05-25 09:43:03 +0000983- Removed all types from the 'types' module that are easily accessable
984 through builtins.
Brett Cannone9fd2312007-10-12 19:18:19 +0000985
Georg Brandl52d168a2008-01-07 18:10:24 +0000986
Guido van Rossum4405cf32007-08-30 17:16:55 +0000987What's New in Python 3.0a1?
Guido van Rossum45aecf42006-03-15 04:58:47 +0000988==========================
Thomas Wouters4d70c3d2006-06-08 14:42:34 +0000989
Guido van Rossum4405cf32007-08-30 17:16:55 +0000990*Release date: 31-Aug-2007*
Neal Norwitz4886cc32006-08-21 17:06:07 +0000991
992Core and Builtins
993-----------------
994
Martin v. Löwis47383402007-08-15 07:32:56 +0000995- PEP 3131: Support non-ASCII identifiers.
996
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000997- PEP 3120: Change default encoding to UTF-8.
998
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000999- PEP 3123: Use proper C inheritance for PyObject.
1000
Guido van Rossumcd16bf62007-06-13 18:07:49 +00001001- Removed the __oct__ and __hex__ special methods and added a bin()
1002 builtin function.
1003
Georg Brandl52b92cc2008-05-25 09:43:03 +00001004- PEP 3127: octal literals now start with "0o". Old-style octal
1005 literals are invalid. There are binary literals with a prefix of
1006 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +00001007
Guido van Rossume7ba4952007-06-06 23:52:48 +00001008- None, True, False are now keywords.
1009
Guido van Rossum29478ef2007-05-29 00:39:44 +00001010- PEP 3119: isinstance() and issubclass() can be overridden.
1011
Guido van Rossumebe3e162007-05-17 18:20:34 +00001012- Remove BaseException.message.
1013
Guido van Rossum1bc535d2007-05-15 18:46:22 +00001014- Remove tuple parameter unpacking (PEP 3113).
1015
Georg Brandl52b92cc2008-05-25 09:43:03 +00001016- Remove the f_restricted attribute from frames. This naturally leads
1017 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +00001018
Georg Brandl52b92cc2008-05-25 09:43:03 +00001019- PEP 3132 was accepted. That means that you can do ``a, *b =
1020 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +00001021
Georg Brandl52b92cc2008-05-25 09:43:03 +00001022- range() now returns an iterator rather than a list. Floats are not
1023 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +00001024
Nick Coghlan650f0d02007-04-15 12:05:43 +00001025- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +00001026 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +00001027
Guido van Rossume27dc722007-03-27 22:37:34 +00001028- By default, != returns the opposite of ==, unless the latter returns
1029 NotImplemented.
1030
Georg Brandl52b92cc2008-05-25 09:43:03 +00001031- Patch #1680961: sys.exitfunc has been removed and replaced with a
1032 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +00001033
Georg Brandl801dd732007-03-18 20:18:31 +00001034- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +00001035 keyword arg in the class statement, which can now use the full
1036 syntax of a parameter list. Also, the metaclass can implement a
1037 __prepare__ function which will be called to create the dictionary
1038 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +00001039
Georg Brandl428f0642007-03-18 18:35:15 +00001040- The long-deprecated argument "pend" of PyFloat_FromString() has been
1041 removed.
1042
Georg Brandle32b4222007-03-10 22:13:27 +00001043- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +00001044 its argument, if it exists. If not, it will work like before. This
1045 allows customizing the output of dir() in the presence of a
1046 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +00001047
Neal Norwitz8dfc4a92007-08-11 06:39:53 +00001048- Removed support for __members__ and __methods__.
1049
Georg Brandle32b4222007-03-10 22:13:27 +00001050- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +00001051
Georg Brandle32b4222007-03-10 22:13:27 +00001052- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001053 functionality formerly known as raw_input(); the name raw_input() is
1054 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +00001055
Georg Brandl52b92cc2008-05-25 09:43:03 +00001056- Classes listed in an 'except' clause must inherit from
1057 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001058
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001059- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001060 and .keys(), .items(), .values() return dict views, which behave
1061 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001062
Guido van Rossum8b545362007-02-09 23:52:14 +00001063- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001064 'softspace' attribute of files is now gone (since print() doesn't
1065 use it). A side effect of this change is that you can get
1066 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001067
1068 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001069 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001070
1071 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001072
Brett Cannon398db8b2007-01-29 23:44:37 +00001073- PEP 3102: keyword-only arguments.
1074
Georg Brandl52b92cc2008-05-25 09:43:03 +00001075- Int/Long unification is complete. The 'long' built-in type and
1076 literals with trailing 'L' or 'l' have been removed. Performance
1077 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001078
1079- 'except E, V' must now be spelled as 'except E as V' and deletes V
1080 at the end of the except clause; V must be a simple name.
1081
Neal Norwitzc1505362006-12-28 06:47:50 +00001082- Added function annotations per PEP 3107.
1083
Georg Brandl52b92cc2008-05-25 09:43:03 +00001084- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001085
1086 >>> def f(x):
1087 ... def inc():
1088 ... nonlocal x
1089 ... x += 1
1090 ... return x
1091 ... return inc
1092 ...
1093 >>> inc = f(0)
1094 >>> inc()
1095 1
1096 >>> inc()
1097 2
1098
Georg Brandl66a796e2006-12-19 20:50:34 +00001099- Moved intern() to sys.intern().
1100
1101- exec is now a function.
1102
1103- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001104
Neal Norwitz4886cc32006-08-21 17:06:07 +00001105- Classic classes are a thing of the past. All classes are new style.
1106
1107- Exceptions *must* derive from BaseException.
1108
1109- Integer division always returns a float. The -Q option is no more.
1110 All the following are gone:
1111 * PyNumber_Divide and PyNumber_InPlaceDivide
1112 * __div__, __rdiv__, and __idiv__
1113 * nb_divide, nb_inplace_divide
1114 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1115 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1116 if we want to re-use __div__ and friends. If we do, it will make
1117 it harder to write code for both 2.x and 3.x.)
1118
1119- 'as' and 'with' are keywords.
1120
1121- Absolute import is the default behavior for 'import foo' etc.
1122
Georg Brandl52b92cc2008-05-25 09:43:03 +00001123- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001124
Georg Brandl52b92cc2008-05-25 09:43:03 +00001125- Removed these Python builtins: apply(), callable(), coerce(),
1126 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001127
Georg Brandl52b92cc2008-05-25 09:43:03 +00001128- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001129
Georg Brandl52b92cc2008-05-25 09:43:03 +00001130- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001131
1132- Remove C API support for restricted execution.
1133
Guido van Rossumcf1be882007-08-30 22:07:17 +00001134- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001135 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001136 sequences of unequal length -- it now stops after the shortest one
1137 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001138
Georg Brandl52b92cc2008-05-25 09:43:03 +00001139- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001140
1141- Added class decorators per PEP 3129.

1144Extension Modules
1145-----------------
1146
Georg Brandl52b92cc2008-05-25 09:43:03 +00001147- Removed the imageop module. Obsolete long with its unit tests
1148 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +00001149
Georg Brandl52b92cc2008-05-25 09:43:03 +00001150- Removed these attributes from the operator module: div, idiv,
1151 __div__, __idiv__, isCallable, sequenceIncludes.
1152
1153- Removed these attributes from the sys module: exc_clear(), exc_type,
1154 exc_value, exc_traceback.

1158-------
1159
Georg Brandl52b92cc2008-05-25 09:43:03 +00001160- Removed the compiler package. Use of the _ast module and (an
1161 eventual) AST -> bytecode mechanism.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001162
Georg Brandl52b92cc2008-05-25 09:43:03 +00001163- Removed these modules: audiodev, Bastion, bsddb185, exceptions,
1164 linuxaudiodev, md5, MimeWriter, mimify, popen2, rexec, sets, sha,
1165 stringold, strop, sunaudiodev, timing, xmllib.
