Mark Dickinsonb0e2b4c2008-04-26 20:48:56 +0000301- Issue #1496032: On alpha, use -mieee when gcc is the compiler.
302
Guido van Rossumdc21db32008-04-07 18:37:41 +0000303- "make install" is now an alias for "make altinstall", to prevent
Georg Brandl52b92cc2008-05-25 09:43:03 +0000304 accidentally overwriting a Python 2.x installation. Use "make
305 fullinstall" to force Python 3.0 to be installed as "python".

317-----------------
318
319- Bug #2301: Don't try decoding the source code into the original
320 encoding for syntax errors.
321
Martin v. Löwis92fab752008-03-08 10:40:41 +0000322Extension Modules
323-----------------
324
Neal Norwitz6cf49cf2008-03-24 06:22:57 +0000325- The dl module was removed, use the ctypes module instead.
326
Martin v. Löwis92fab752008-03-08 10:40:41 +0000327- Use wchar_t functions in _locale module.

330-------
331
Georg Brandl52b92cc2008-05-25 09:43:03 +0000332- The class distutils.commands.build_py.build_py_2to3 can be used as a
333 build_py replacement to automatically run 2to3 on modules that are
334 going to be installed.
Martin v. Löwis73a22f02008-03-22 00:35:10 +0000335
Guido van Rossumf4169812008-03-17 22:56:06 +0000336- A new pickle protocol (protocol 3) is added with explicit support
337 for bytes. This is the default protocol. It intentionally cannot
338 be unpickled by Python 2.x.
339
340- When a pickle written by Python 2.x contains an (8-bit) str
341 instance, this is now decoded to a (Unicode) str instance. The
342 encoding used to do this defaults to ASCII, but can be overridden
343 via two new keyword arguments to the Unpickler class. Previously
344 this would create bytes instances, which is usually wrong: str
345 instances are often used to pickle attribute names etc., and text is
346 more common than binary data anyway.
347
Martin v. Löwis071ef772008-03-08 11:24:24 +0000348- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000349 system doesn't support CODESET and LANG isn't set or doesn't allow
350 deduction of an encoding.
Martin v. Löwis071ef772008-03-08 11:24:24 +0000351
Georg Brandl52b92cc2008-05-25 09:43:03 +0000352- Issue #1202: zlib.crc32 and zlib.adler32 now return an unsigned
353 value.
Gregory P. Smith425136b2008-03-17 20:45:21 +0000354
Georg Brandl52b92cc2008-05-25 09:43:03 +0000355- Issue #719888: Updated tokenize to use a bytes API. generate_tokens
356 has been renamed tokenize and now works with bytes rather than
357 strings. A new detect_encoding function has been added for
358 determining source file encoding according to PEP-0263. Token
359 sequences returned by tokenize always start with an ENCODING token
360 which specifies the encoding used to decode the file. This token is
361 used to encode the output of untokenize back to bytes.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000372- Issue #2282: io.TextIOWrapper was not overriding seekable() from
373 io.IOBase.
Ka-Ping Yeeddaa7062008-03-17 20:35:15 +0000374
Georg Brandl52b92cc2008-05-25 09:43:03 +0000375- Issue #2115: Important speedup in setting __slot__ attributes. Also
376 prevent a possible crash: an Abstract Base Class would try to access
377 a slot on a registered virtual subclass.
Christian Heimesa156e092008-02-16 07:38:31 +0000378
Georg Brandl52b92cc2008-05-25 09:43:03 +0000379- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl52b92cc2008-05-25 09:43:03 +0000382- Clear all free list during a gc.collect() of the highest generation
383 in order to allow pymalloc to free more arenas. Python may give back
384 memory to the OS earlier.
Christian Heimesa156e092008-02-16 07:38:31 +0000385
Georg Brandl52b92cc2008-05-25 09:43:03 +0000386- Issue #2045: Fix an infinite recursion triggered when printing a

388 to a bound method.
Christian Heimesa156e092008-02-16 07:38:31 +0000389
390- Fixed a minor memory leak in dictobject.c. The content of the free
391 list was not freed on interpreter shutdown.
392
Georg Brandl52b92cc2008-05-25 09:43:03 +0000393- Limit free list of method and builtin function objects to 256
394 entries each.
Christian Heimesa156e092008-02-16 07:38:31 +0000395
Georg Brandl52b92cc2008-05-25 09:43:03 +0000396- Patch #1953: Added ``sys._compact_freelists()`` and the C API
397 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000398 to compact the internal free lists of pre-allocted ints and floats.
399
400- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000401 Python expected the return type int but the fork familie returns
402 pi_t.
Christian Heimesa156e092008-02-16 07:38:31 +0000403
Georg Brandl52b92cc2008-05-25 09:43:03 +0000404- Issue #1678380: Fix a bug that identifies 0j and -0j when they
405 appear in the same code unit.
Christian Heimesa156e092008-02-16 07:38:31 +0000406
Georg Brandl52b92cc2008-05-25 09:43:03 +0000407- Issue #2025: Added tuple.count() and tuple.index() methods to comply
408 with the collections.Sequence API.
Raymond Hettinger65baa342008-02-07 00:41:02 +0000409
Georg Brandl52b92cc2008-05-25 09:43:03 +0000410- Fixed multiple reinitialization of the Python interpreter. The small
411 int list in longobject.c has caused a seg fault during the third
412 finalization.
Christian Heimesdfc12ed2008-01-31 15:16:38 +0000413

Georg Brandl52b92cc2008-05-25 09:43:03 +0000428- Issue #1762972: __file__ points to the source file instead of the
429 pyc/pyo file if the py file exists.
Christian Heimes3b06e532008-01-07 20:12:44 +0000430
Guido van Rossumab078dd2008-01-06 00:09:11 +0000431- Issue #1393: object_richcompare() returns NotImplemented instead of
432 False if the objects aren't equal, to give the other side a chance.
433
Guido van Rossume239b002008-01-06 00:44:20 +0000434- Issue #1692: Interpreter was not displaying location of SyntaxError.
Kurt B. Kaiser43b15092008-01-05 04:32:22 +0000435
Georg Brandl52b92cc2008-05-25 09:43:03 +0000436- Improve some exception messages when Windows fails to load an
437 extension module. Now we get for example '%1 is not a valid Win32
438 application' instead of 'error code 193'. Also use Unicode strings
439 to deal with non-English locales.
Amaury Forgeot d'Arcbccd63c2008-01-04 01:21:27 +0000440
Georg Brandl52b92cc2008-05-25 09:43:03 +0000441- Issue #1587: Added instancemethod wrapper for PyCFunctions. The
442 Python C API has gained a new type *PyInstanceMethod_Type* and the
443 functions *PyInstanceMethod_Check(o)*, *PyInstanceMethod_New(func)*
444 and *PyInstanceMethod_Function(im)*.
Christian Heimesa3534a62007-12-11 19:56:40 +0000445
Georg Brandl52b92cc2008-05-25 09:43:03 +0000446- Constants gc.DEBUG_OBJECT and gc.DEBUG_INSTANCE have been removed
447 from the gc module; gc.DEBUG_COLLECTABLE or gc.DEBUG_UNCOLLECTABLE
448 are now enough to print the corresponding list of objects considered
449 by the garbage collector.
Amaury Forgeot d'Arcad8dcd52007-12-10 23:58:35 +0000450
Georg Brandl52b92cc2008-05-25 09:43:03 +0000451- Issue #1573: Improper use of the keyword-only syntax makes the
452 parser crash.
Christian Heimesbc873412007-12-08 22:11:32 +0000453
Georg Brandl52b92cc2008-05-25 09:43:03 +0000454- Issue #1564: The set implementation should special-case PyUnicode

463 mountpoint.
Christian Heimes7131fd92008-02-19 14:21:46 +0000464
Georg Brandl52b92cc2008-05-25 09:43:03 +0000465- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
466 the first chunk fed to the decoder started with a BOM, but was
467 longer than 3 bytes.
Christian Heimes7131fd92008-02-19 14:21:46 +0000468

Georg Brandl52b92cc2008-05-25 09:43:03 +0000489- Created new UserDict class in collections module. This one inherits
490 from and complies with the MutableMapping ABC. Also, moved
491 UserString and UserList to the collections module. The
492 MutableUserString class was removed.
Raymond Hettinger48b8b662008-02-05 01:53:00 +0000493
Guido van Rossumea6775b2008-02-21 20:16:31 +0000494- Removed UserDict.DictMixin. Replaced all its uses with

528-----------------
529
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000530- str8 now has the same construction signature as bytes.
531
Georg Brandl52b92cc2008-05-25 09:43:03 +0000532- Comparisons between str and str8 now return False/True for ==/!=.
533 sqlite3 returns str8 when recreating on object from it's __conform__
534 value. The struct module returns str8 for all string-related
535 formats. This was true before this change, but becomes more
536 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000537
Georg Brandl52b92cc2008-05-25 09:43:03 +0000538- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
539 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000540
541- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
542
543- Changed `__file__` and `co_filename` to unicode. The path names are decoded
544 with `Py_FileSystemDefaultEncoding` and a new API method
545 `PyUnicode_DecodeFSDefault(char*)` was added.
546
Georg Brandl52b92cc2008-05-25 09:43:03 +0000547- io.open() and _fileio.FileIO have grown a new argument closefd. A
548 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000549
Georg Brandl52b92cc2008-05-25 09:43:03 +0000550- Added a new option -b to issues warnings (-bb for errors) about
551 certain operations between bytes/buffer and str like str(b'') and
552 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000553
Georg Brandl52b92cc2008-05-25 09:43:03 +0000554- The standards streams sys.stdin, stdout and stderr may be None when
555 the when the C runtime library returns an invalid file descriptor
556 for the streams (fileno(stdin) < 0). For now this happens only for
557 Windows GUI apps and scripts started with `pythonw.exe`.

Christian Heimesbce52be2007-11-17 19:08:41 +0000559- Added PCbuild9 directory for VS 2008.
560
Georg Brandl52b92cc2008-05-25 09:43:03 +0000561- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
562 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000563
Georg Brandl52b92cc2008-05-25 09:43:03 +0000564- Unbound methods are gone for good. ClassObject.method returns an
565 ordinary function object, instance.method still returns a bound
566 method object. The API of bound methods is cleaned up, too. The
567 im_class attribute is removed and im_func + im_self are renamed to
568 __func__ and __self__. The factory PyMethod_New takes only func and

Georg Brandl52b92cc2008-05-25 09:43:03 +0000571- intobject.h is no longer included by Python.h. The remains were
572 moved to longobject.h. It still exists to define several aliases
573 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000574
Christian Heimesa37d4c62007-12-04 23:02:19 +0000575- Removed sys.maxint, use sys.maxsize instead.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000585- When loading an external file using testfile(), the passed-in
586 encoding argument was being ignored if __loader__ is defined and
587 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000588
Georg Brandl52b92cc2008-05-25 09:43:03 +0000589- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
590 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000591

Guido van Rossum4405cf32007-08-30 17:16:55 +0000601*Release date: 31-Aug-2007*
Neal Norwitz4886cc32006-08-21 17:06:07 +0000602
603Core and Builtins
604-----------------
605
Martin v. Löwis47383402007-08-15 07:32:56 +0000606- PEP 3131: Support non-ASCII identifiers.
607
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000608- PEP 3120: Change default encoding to UTF-8.
609
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000610- PEP 3123: Use proper C inheritance for PyObject.
611
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000612- Removed the __oct__ and __hex__ special methods and added a bin()
613 builtin function.
614
Georg Brandl52b92cc2008-05-25 09:43:03 +0000615- PEP 3127: octal literals now start with "0o". Old-style octal
616 literals are invalid. There are binary literals with a prefix of
617 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000618
Guido van Rossume7ba4952007-06-06 23:52:48 +0000619- None, True, False are now keywords.
620
Guido van Rossum29478ef2007-05-29 00:39:44 +0000621- PEP 3119: isinstance() and issubclass() can be overridden.
622
Guido van Rossumebe3e162007-05-17 18:20:34 +0000623- Remove BaseException.message.
624
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000625- Remove tuple parameter unpacking (PEP 3113).
626
Georg Brandl52b92cc2008-05-25 09:43:03 +0000627- Remove the f_restricted attribute from frames. This naturally leads
628 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000629
Georg Brandl52b92cc2008-05-25 09:43:03 +0000630- PEP 3132 was accepted. That means that you can do ``a, *b =
631 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000632
Georg Brandl52b92cc2008-05-25 09:43:03 +0000633- range() now returns an iterator rather than a list. Floats are not
634 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000635
Nick Coghlan650f0d02007-04-15 12:05:43 +0000636- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000637 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000638
Guido van Rossume27dc722007-03-27 22:37:34 +0000639- By default, != returns the opposite of ==, unless the latter returns
640 NotImplemented.
641
Georg Brandl52b92cc2008-05-25 09:43:03 +0000642- Patch #1680961: sys.exitfunc has been removed and replaced with a
643 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000644
Georg Brandl801dd732007-03-18 20:18:31 +0000645- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000646 keyword arg in the class statement, which can now use the full
647 syntax of a parameter list. Also, the metaclass can implement a
648 __prepare__ function which will be called to create the dictionary
649 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000650
Georg Brandl428f0642007-03-18 18:35:15 +0000651- The long-deprecated argument "pend" of PyFloat_FromString() has been
652 removed.
653
Georg Brandle32b4222007-03-10 22:13:27 +0000654- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000655 its argument, if it exists. If not, it will work like before. This
656 allows customizing the output of dir() in the presence of a
657 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000658
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000659- Removed support for __members__ and __methods__.
660
Georg Brandle32b4222007-03-10 22:13:27 +0000661- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000662
Georg Brandle32b4222007-03-10 22:13:27 +0000663- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000664 functionality formerly known as raw_input(); the name raw_input() is
665 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000666
Georg Brandl52b92cc2008-05-25 09:43:03 +0000667- Classes listed in an 'except' clause must inherit from
668 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000669
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000670- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000671 and .keys(), .items(), .values() return dict views, which behave
672 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000673
Guido van Rossum8b545362007-02-09 23:52:14 +0000674- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000675 'softspace' attribute of files is now gone (since print() doesn't
676 use it). A side effect of this change is that you can get
677 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +0000678
679 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000680 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +0000681
682 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +0000683
Brett Cannon398db8b2007-01-29 23:44:37 +0000684- PEP 3102: keyword-only arguments.
685
Georg Brandl52b92cc2008-05-25 09:43:03 +0000686- Int/Long unification is complete. The 'long' built-in type and
687 literals with trailing 'L' or 'l' have been removed. Performance
688 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000689
690- 'except E, V' must now be spelled as 'except E as V' and deletes V
691 at the end of the except clause; V must be a simple name.
692
Neal Norwitzc1505362006-12-28 06:47:50 +0000693- Added function annotations per PEP 3107.
694
Georg Brandl52b92cc2008-05-25 09:43:03 +0000695- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +0000696
697 >>> def f(x):
698 ... def inc():
699 ... nonlocal x
700 ... x += 1
701 ... return x
702 ... return inc
703 ...
704 >>> inc = f(0)
705 >>> inc()
706 1
707 >>> inc()
708 2
709
Georg Brandl66a796e2006-12-19 20:50:34 +0000710- Moved intern() to sys.intern().
711
712- exec is now a function.
713
714- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000715
Neal Norwitz4886cc32006-08-21 17:06:07 +0000716- Classic classes are a thing of the past. All classes are new style.
717
718- Exceptions *must* derive from BaseException.
719
720- Integer division always returns a float. The -Q option is no more.
721 All the following are gone:
722 * PyNumber_Divide and PyNumber_InPlaceDivide
723 * __div__, __rdiv__, and __idiv__
724 * nb_divide, nb_inplace_divide
725 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
726 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
727 if we want to re-use __div__ and friends. If we do, it will make
728 it harder to write code for both 2.x and 3.x.)
729
730- 'as' and 'with' are keywords.
731
732- Absolute import is the default behavior for 'import foo' etc.
733
Georg Brandl52b92cc2008-05-25 09:43:03 +0000734- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000735
Georg Brandl52b92cc2008-05-25 09:43:03 +0000736- Removed these Python builtins: apply(), callable(), coerce(),
737 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +0000738
Georg Brandl52b92cc2008-05-25 09:43:03 +0000739- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000740
Georg Brandl52b92cc2008-05-25 09:43:03 +0000741- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000742
743- Remove C API support for restricted execution.
744
Guido van Rossumcf1be882007-08-30 22:07:17 +0000745- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +0000746 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +0000747 sequences of unequal length -- it now stops after the shortest one
748 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000749
Georg Brandl52b92cc2008-05-25 09:43:03 +0000750- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000751
752- Added class decorators per PEP 3129.
