Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +000042 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
43 although under Windows it fails at a later point.

Benjamin Peterson791dc2f2008-09-05 23:27:15 +000045- Issue #3279: Importing site at interpreter was failing silently because the
46 site module uses the open builtin which was not initialized at the time.
47
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000048- Issue #3660: Corrected a reference leak in str.encode() when the encoder
49 does not return a bytes object.
50
51- Issue #3774: Added a few more checks in PyTokenizer_FindEncoding to handle
Amaury Forgeot d'Arc1b933ed2008-09-04 22:34:09 +000052 error conditions.
53
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000054- Issue #3594: Fix Parser/tokenizer.c:fp_setreadl() to open the file being
Brett Cannon8a9583e2008-09-04 05:04:25 +000055 tokenized by either a file path or file pointer for the benefit of
56 PyTokenizer_FindEncoding().
57
Antoine Pitroufff95302008-09-03 18:58:51 +000058- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
59 these systems, the mbstowcs() function is slightly buggy and must be
60 replaced with strlen() for the purpose of counting of number of wide
61 characters needed to represent the multi-byte character string.
62
Antoine Pitrou658fad82008-09-03 18:34:34 +000063- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"
64 could be easily encountered under Windows in debug mode when exercising
65 the recursion limit checking code, due to bogus handling of recursion
66 limit when USE_STACKCHEK was enabled.
67
Brett Cannon54bd41d2008-09-02 04:01:42 +000068- Issue 3639: The _warnings module could segfault the interpreter when
69 unexpected types were passed in as arguments.
70
Antoine Pitrouc6b09eb2008-09-01 15:10:14 +000071- Issue #3712: The memoryview object had a reference leak and didn't support
72 cyclic garbage collection.

75 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
76 was correctly parsed but parsing of subsequent arguments failed.
77
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +000078- Issue #3611: An exception __context__ could be cleared in a complex pattern
79 involving a __del__ method re-raising an exception.

Antoine Pitrouec569b72008-08-26 22:40:48 +000081- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
82 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
83 mechanism. In the process, fix a bug where isinstance() and issubclass(),
84 when given a tuple of classes as second argument, were looking up
85 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
86 type object.
87
Antoine Pitroue2dffc02008-08-26 22:02:58 +000088- Issue #3663: Py_None was decref'd when printing SyntaxErrors.

141 tkinter.BaseWidget and tkinter.scrolledtext.ScrolledText.
142
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000143- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000144 It is now maintained outside of the standard library at

173
Jesus Cea6ba33292008-08-31 14:12:11 +0000174- bsddb code updated to version 4.7.3pre2. This code is the same than
175 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
176 The Python code is automatically translated using "2to3". Please, do not
177 update this code in Python 3.0 by hand. Update the 2.6 one and then
178 do "2to3".
179
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000180- The _bytesio and _stringio modules are now compiled into the python binary.

Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000204What's new in Python 3.0b3?
205===========================
206
Barry Warsaw57c10582008-08-21 02:39:51 +0000207*Release date: 20-Aug-2008*
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000208
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000209Core and Builtins
210-----------------
211
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000212- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
213 arguments.
214
Antoine Pitrou616d2852008-08-19 22:09:34 +0000215- Issue #2394: implement more of the memoryview API, with the caveat that
216 only one-dimensional contiguous buffers are supported and exercised right
217 now. Slicing, slice assignment and comparison (equality and inequality)
218 have been added. Also, the tolist() method has been implemented, but only
219 for byte buffers. Endly, the API has been updated to return bytes objects
220 wherever it used to return bytearrays.
221
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000222- Issue #3560: clean up the new C PyMemoryView API so that naming is
223 internally consistent; add macros PyMemoryView_GET_BASE() and
224 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
225 without relying on a particular implementation; remove the ill-named
226 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
227
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000228- ctypes function pointers that are COM methods have a boolean True
229 value again.
230
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000231- Issue #1819: function calls with several named parameters are now on
232 average 35% faster (as measured by pybench).
233
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000234- The undocumented C APIs PyUnicode_AsString() and
235 PyUnicode_AsStringAndSize() were made private to the interpreter, in
236 order to be able to refine their interfaces for Python 3.1.
237
238 If you need to access the UTF-8 representation of a Unicode object
239 as bytes string, please use PyUnicode_AsUTF8String() instead.
240
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000241- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
242 to Python 3.0's stricter semantics which allow to avoid successive
243 reallocations of the result string (this also affects str.join()).
244

Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000246Library
247-------
248
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000249- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
250 a build problem on MacOS with CJK locales. It adds four temporary
251 mappings to existing legacy codecs that are virtually compatible
252 with Mac encodings. They will be replaced by codecs correctly
253 implemented in 3.1.
254
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000255- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
256 "global name 'header' is not defined".
257
Antoine Pitroufd036452008-08-19 17:56:33 +0000258- Issue #2834: update the regular expression library to match the unicode
259 standards of py3k. In other words, mixing bytes and unicode strings
260 (be it as pattern, search string or replacement string) raises a TypeError.
261 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
262 and can be disabled by specifying a new re.ASCII flag; as for bytes
263 patterns, ASCII matching is the only option and trying to specify re.UNICODE
264 for such patterns raises a ValueError.
265
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000266- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
267 Code contributed by Matt Giuca. quote() now encodes the input
268 before quoting, unquote() decodes after unquoting. There are
269 new arguments to change the encoding and errors settings.
270 There are also new APIs to skip the encode/decode steps.
271 [un]quote_plus() are also affected.
272
Nick Coghlan36f49522008-08-18 12:31:52 +0000273- Issue #2235: numbers.Number now blocks inheritance of the default id()
274 based hash because that hash mechanism is not correct for numeric types.
275 All concrete numeric types that inherit from Number (rather than just
276 registering with it) must explicitly provide a hash implementation in
277 order for their instances to be hashable.
278
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000279- Issue #2676: in the email package, content-type parsing was hanging on
280 pathological input because of quadratic or exponential behaviour of a
281 regular expression.
282
Antoine Pitrou87695762008-08-14 22:44:29 +0000283- Issue #3476: binary buffered reading through the new "io" library is now
284 thread-safe.
285
Robert Schuppenies3d1c7de2008-08-10 11:28:17 +0000286- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
287 menu entries were not deleted.
288
Lars Gustäbel0c24e8b2008-08-02 11:43:24 +0000289- Remove the TarFileCompat class from tarfile.py.
290
Amaury Forgeot d'Arcbdbddf82008-08-01 00:06:49 +0000291- Issue #2491: os.fdopen is now almost an alias for the built-in open(), and
292 accepts the same parameters. It just checks that its first argument is an
293 integer.
294
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000295- Issue #3394: zipfile.writestr sets external attributes when passed a
296 file name rather than a ZipInfo instance, so files are extracted with
297 mode 0600 rather than 000 under Unix.
298
Antoine Pitrouc66f9092008-07-28 19:46:11 +0000299- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
300 asking for a specific length.

314
Mark Dickinson65fe25e2008-07-16 11:30:51 +0000315- Issue #3008: the float type has a new instance method 'float.hex'
316 and a new class method 'float.fromhex' to convert floating-point
317 numbers to and from hexadecimal strings, respectively.
318
Eric Smithd68af8f2008-07-16 00:15:35 +0000319- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
320 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
321
Amaury Forgeot d'Arca4db6862008-07-04 21:26:43 +0000322- Issue #3280: like chr(), the "%c" format now accepts unicode code points
323 beyond the Basic Multilingual Plane (above 0xffff) on all configurations. On
324 "narrow Unicode" builds, the result is a string of 2 code units, forming a
325 UTF-16 surrogate pair.
326
Georg Brandld52429f2008-07-04 15:55:02 +0000327- Issue #3282: str.isprintable() should return False for undefined

Guido van Rossumdc21db32008-04-07 18:37:41 +0000634- "make install" is now an alias for "make altinstall", to prevent
Georg Brandl52b92cc2008-05-25 09:43:03 +0000635 accidentally overwriting a Python 2.x installation. Use "make

650- Bug #2301: Don't try decoding the source code into the original
651 encoding for syntax errors.

654-----------------
655
Neal Norwitz6cf49cf2008-03-24 06:22:57 +0000656- The dl module was removed, use the ctypes module instead.
657
Martin v. Löwis92fab752008-03-08 10:40:41 +0000658- Use wchar_t functions in _locale module.

661-------
662
Georg Brandl52b92cc2008-05-25 09:43:03 +0000663- The class distutils.commands.build_py.build_py_2to3 can be used as a
664 build_py replacement to automatically run 2to3 on modules that are
665 going to be installed.
Martin v. Löwis73a22f02008-03-22 00:35:10 +0000666
Guido van Rossumf4169812008-03-17 22:56:06 +0000667- A new pickle protocol (protocol 3) is added with explicit support
668 for bytes. This is the default protocol. It intentionally cannot
669 be unpickled by Python 2.x.
670
671- When a pickle written by Python 2.x contains an (8-bit) str
672 instance, this is now decoded to a (Unicode) str instance. The
673 encoding used to do this defaults to ASCII, but can be overridden
674 via two new keyword arguments to the Unpickler class. Previously
675 this would create bytes instances, which is usually wrong: str
676 instances are often used to pickle attribute names etc., and text is
677 more common than binary data anyway.
678
Martin v. Löwis071ef772008-03-08 11:24:24 +0000679- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000680 system doesn't support CODESET and LANG isn't set or doesn't allow
681 deduction of an encoding.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000683- Issue #1202: zlib.crc32 and zlib.adler32 now return an unsigned
684 value.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000686- Issue #719888: Updated tokenize to use a bytes API. generate_tokens
687 has been renamed tokenize and now works with bytes rather than
688 strings. A new detect_encoding function has been added for
689 determining source file encoding according to PEP-0263. Token
690 sequences returned by tokenize always start with an ENCODING token
691 which specifies the encoding used to decode the file. This token is
692 used to encode the output of untokenize back to bytes.

719 to a bound method.
Christian Heimesa156e092008-02-16 07:38:31 +0000720
721- Fixed a minor memory leak in dictobject.c. The content of the free
722 list was not freed on interpreter shutdown.
723
Georg Brandl52b92cc2008-05-25 09:43:03 +0000724- Limit free list of method and builtin function objects to 256
725 entries each.
Christian Heimesa156e092008-02-16 07:38:31 +0000726
Georg Brandl52b92cc2008-05-25 09:43:03 +0000727- Patch #1953: Added ``sys._compact_freelists()`` and the C API
728 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000729 to compact the internal free lists of pre-allocted ints and floats.
730
731- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000732 Python expected the return type int but the fork familie returns
733 pi_t.
Christian Heimesa156e092008-02-16 07:38:31 +0000734

736 appear in the same code unit.
Christian Heimesa156e092008-02-16 07:38:31 +0000737
Georg Brandl52b92cc2008-05-25 09:43:03 +0000738- Issue #2025: Added tuple.count() and tuple.index() methods to comply
739 with the collections.Sequence API.
Raymond Hettinger65baa342008-02-07 00:41:02 +0000740
Georg Brandl52b92cc2008-05-25 09:43:03 +0000741- Fixed multiple reinitialization of the Python interpreter. The small
742 int list in longobject.c has caused a seg fault during the third
743 finalization.
Christian Heimesdfc12ed2008-01-31 15:16:38 +0000744

Christian Heimes3b06e532008-01-07 20:12:44 +0000761
Guido van Rossumab078dd2008-01-06 00:09:11 +0000762- Issue #1393: object_richcompare() returns NotImplemented instead of
763 False if the objects aren't equal, to give the other side a chance.
764
Guido van Rossume239b002008-01-06 00:44:20 +0000765- Issue #1692: Interpreter was not displaying location of SyntaxError.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000767- Improve some exception messages when Windows fails to load an
768 extension module. Now we get for example '%1 is not a valid Win32
769 application' instead of 'error code 193'. Also use Unicode strings
770 to deal with non-English locales.
Amaury Forgeot d'Arcbccd63c2008-01-04 01:21:27 +0000771
Georg Brandl52b92cc2008-05-25 09:43:03 +0000772- Issue #1587: Added instancemethod wrapper for PyCFunctions. The

860
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000861- str8 now has the same construction signature as bytes.
862
Georg Brandl52b92cc2008-05-25 09:43:03 +0000863- Comparisons between str and str8 now return False/True for ==/!=.
864 sqlite3 returns str8 when recreating on object from it's __conform__
865 value. The struct module returns str8 for all string-related
866 formats. This was true before this change, but becomes more
867 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000868
Georg Brandl52b92cc2008-05-25 09:43:03 +0000869- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
870 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000871
872- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
873
874- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000875 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000876 `PyUnicode_DecodeFSDefault(char*)` was added.
877
Georg Brandl52b92cc2008-05-25 09:43:03 +0000878- io.open() and _fileio.FileIO have grown a new argument closefd. A
879 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000880
Georg Brandl52b92cc2008-05-25 09:43:03 +0000881- Added a new option -b to issues warnings (-bb for errors) about
882 certain operations between bytes/buffer and str like str(b'') and
883 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000884
Georg Brandl52b92cc2008-05-25 09:43:03 +0000885- The standards streams sys.stdin, stdout and stderr may be None when
886 the when the C runtime library returns an invalid file descriptor
887 for the streams (fileno(stdin) < 0). For now this happens only for
888 Windows GUI apps and scripts started with `pythonw.exe`.

Christian Heimesbce52be2007-11-17 19:08:41 +0000890- Added PCbuild9 directory for VS 2008.
891
Georg Brandl52b92cc2008-05-25 09:43:03 +0000892- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
893 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000894
Georg Brandl52b92cc2008-05-25 09:43:03 +0000895- Unbound methods are gone for good. ClassObject.method returns an
896 ordinary function object, instance.method still returns a bound
897 method object. The API of bound methods is cleaned up, too. The
898 im_class attribute is removed and im_func + im_self are renamed to
899 __func__ and __self__. The factory PyMethod_New takes only func and
900 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000901
Georg Brandl52b92cc2008-05-25 09:43:03 +0000902- intobject.h is no longer included by Python.h. The remains were
903 moved to longobject.h. It still exists to define several aliases
904 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000905
Christian Heimesa37d4c62007-12-04 23:02:19 +0000906- Removed sys.maxint, use sys.maxsize instead.

915
Georg Brandl52b92cc2008-05-25 09:43:03 +0000916- When loading an external file using testfile(), the passed-in
917 encoding argument was being ignored if __loader__ is defined and
918 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000919
Georg Brandl52b92cc2008-05-25 09:43:03 +0000920- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
921 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000922

Neal Norwitz4886cc32006-08-21 17:06:07 +0000933
934Core and Builtins
935-----------------
936
Martin v. Löwis47383402007-08-15 07:32:56 +0000937- PEP 3131: Support non-ASCII identifiers.
938
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000939- PEP 3120: Change default encoding to UTF-8.
940
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000941- PEP 3123: Use proper C inheritance for PyObject.
942
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000943- Removed the __oct__ and __hex__ special methods and added a bin()
944 builtin function.
945
Georg Brandl52b92cc2008-05-25 09:43:03 +0000946- PEP 3127: octal literals now start with "0o". Old-style octal
947 literals are invalid. There are binary literals with a prefix of
948 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000949
Guido van Rossume7ba4952007-06-06 23:52:48 +0000950- None, True, False are now keywords.
951
Guido van Rossum29478ef2007-05-29 00:39:44 +0000952- PEP 3119: isinstance() and issubclass() can be overridden.
953
Guido van Rossumebe3e162007-05-17 18:20:34 +0000954- Remove BaseException.message.
955
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000956- Remove tuple parameter unpacking (PEP 3113).
957
Georg Brandl52b92cc2008-05-25 09:43:03 +0000958- Remove the f_restricted attribute from frames. This naturally leads
959 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000960
Georg Brandl52b92cc2008-05-25 09:43:03 +0000961- PEP 3132 was accepted. That means that you can do ``a, *b =
962 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000963
Georg Brandl52b92cc2008-05-25 09:43:03 +0000964- range() now returns an iterator rather than a list. Floats are not
965 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000966
Nick Coghlan650f0d02007-04-15 12:05:43 +0000967- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000968 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000969
Guido van Rossume27dc722007-03-27 22:37:34 +0000970- By default, != returns the opposite of ==, unless the latter returns
971 NotImplemented.
972
Georg Brandl52b92cc2008-05-25 09:43:03 +0000973- Patch #1680961: sys.exitfunc has been removed and replaced with a
974 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000975
Georg Brandl801dd732007-03-18 20:18:31 +0000976- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000977 keyword arg in the class statement, which can now use the full
978 syntax of a parameter list. Also, the metaclass can implement a
979 __prepare__ function which will be called to create the dictionary
980 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000981
Georg Brandl428f0642007-03-18 18:35:15 +0000982- The long-deprecated argument "pend" of PyFloat_FromString() has been
983 removed.
984
Georg Brandle32b4222007-03-10 22:13:27 +0000985- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000986 its argument, if it exists. If not, it will work like before. This
987 allows customizing the output of dir() in the presence of a
988 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000989
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000990- Removed support for __members__ and __methods__.
991
Georg Brandle32b4222007-03-10 22:13:27 +0000992- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000993
Georg Brandle32b4222007-03-10 22:13:27 +0000994- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000995 functionality formerly known as raw_input(); the name raw_input() is
996 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000997
Georg Brandl52b92cc2008-05-25 09:43:03 +0000998- Classes listed in an 'except' clause must inherit from
999 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001000
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001001- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001002 and .keys(), .items(), .values() return dict views, which behave
1003 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001004
Guido van Rossum8b545362007-02-09 23:52:14 +00001005- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001006 'softspace' attribute of files is now gone (since print() doesn't
1007 use it). A side effect of this change is that you can get
1008 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001009
1010 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001011 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001012
1013 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001014
Brett Cannon398db8b2007-01-29 23:44:37 +00001015- PEP 3102: keyword-only arguments.
1016
Georg Brandl52b92cc2008-05-25 09:43:03 +00001017- Int/Long unification is complete. The 'long' built-in type and
1018 literals with trailing 'L' or 'l' have been removed. Performance
1019 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001020
1021- 'except E, V' must now be spelled as 'except E as V' and deletes V
1022 at the end of the except clause; V must be a simple name.
1023
Neal Norwitzc1505362006-12-28 06:47:50 +00001024- Added function annotations per PEP 3107.
1025
Georg Brandl52b92cc2008-05-25 09:43:03 +00001026- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001027
1028 >>> def f(x):
1029 ... def inc():
1030 ... nonlocal x
1031 ... x += 1
1032 ... return x
1033 ... return inc
1034 ...
1035 >>> inc = f(0)
1036 >>> inc()
1037 1
1038 >>> inc()
1039 2
1040
Georg Brandl66a796e2006-12-19 20:50:34 +00001041- Moved intern() to sys.intern().
1042
1043- exec is now a function.
1044
1045- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001046
Neal Norwitz4886cc32006-08-21 17:06:07 +00001047- Classic classes are a thing of the past. All classes are new style.
1048
1049- Exceptions *must* derive from BaseException.
1050
1051- Integer division always returns a float. The -Q option is no more.
1052 All the following are gone:
1053 * PyNumber_Divide and PyNumber_InPlaceDivide
1054 * __div__, __rdiv__, and __idiv__
1055 * nb_divide, nb_inplace_divide
1056 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1057 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1058 if we want to re-use __div__ and friends. If we do, it will make
1059 it harder to write code for both 2.x and 3.x.)
1060
1061- 'as' and 'with' are keywords.
1062
1063- Absolute import is the default behavior for 'import foo' etc.
1064
Georg Brandl52b92cc2008-05-25 09:43:03 +00001065- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001066
Georg Brandl52b92cc2008-05-25 09:43:03 +00001067- Removed these Python builtins: apply(), callable(), coerce(),
1068 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001069
Georg Brandl52b92cc2008-05-25 09:43:03 +00001070- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001071
Georg Brandl52b92cc2008-05-25 09:43:03 +00001072- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001073
1074- Remove C API support for restricted execution.
1075
Guido van Rossumcf1be882007-08-30 22:07:17 +00001076- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001077 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001078 sequences of unequal length -- it now stops after the shortest one
1079 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001080
Georg Brandl52b92cc2008-05-25 09:43:03 +00001081- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001082
1083- Added class decorators per PEP 3129.

Guido van Rossumd59da4b2007-05-22 18:11:13 +00001119
Georg Brandl52b92cc2008-05-25 09:43:03 +00001120- Removed support for long obsolete platforms: plat-aix3, plat-irix5.
