309-----------------
310
311- Bug #2301: Don't try decoding the source code into the original
312 encoding for syntax errors.
313
Martin v. Löwis92fab752008-03-08 10:40:41 +0000314Extension Modules
315-----------------
316
Neal Norwitz6cf49cf2008-03-24 06:22:57 +0000317- The dl module was removed, use the ctypes module instead.
318
Martin v. Löwis92fab752008-03-08 10:40:41 +0000319- Use wchar_t functions in _locale module.

322-------
323
Georg Brandl52b92cc2008-05-25 09:43:03 +0000324- The class distutils.commands.build_py.build_py_2to3 can be used as a
325 build_py replacement to automatically run 2to3 on modules that are
326 going to be installed.
Martin v. Löwis73a22f02008-03-22 00:35:10 +0000327
Guido van Rossumf4169812008-03-17 22:56:06 +0000328- A new pickle protocol (protocol 3) is added with explicit support
329 for bytes. This is the default protocol. It intentionally cannot
330 be unpickled by Python 2.x.
331
332- When a pickle written by Python 2.x contains an (8-bit) str
333 instance, this is now decoded to a (Unicode) str instance. The
334 encoding used to do this defaults to ASCII, but can be overridden
335 via two new keyword arguments to the Unpickler class. Previously
336 this would create bytes instances, which is usually wrong: str
337 instances are often used to pickle attribute names etc., and text is
338 more common than binary data anyway.
339
Martin v. Löwis071ef772008-03-08 11:24:24 +0000340- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000341 system doesn't support CODESET and LANG isn't set or doesn't allow
342 deduction of an encoding.
Martin v. Löwis071ef772008-03-08 11:24:24 +0000343
Georg Brandl52b92cc2008-05-25 09:43:03 +0000344- Issue #1202: zlib.crc32 and zlib.adler32 now return an unsigned
345 value.
Gregory P. Smith425136b2008-03-17 20:45:21 +0000346
Georg Brandl52b92cc2008-05-25 09:43:03 +0000347- Issue #719888: Updated tokenize to use a bytes API. generate_tokens
348 has been renamed tokenize and now works with bytes rather than
349 strings. A new detect_encoding function has been added for
350 determining source file encoding according to PEP-0263. Token
351 sequences returned by tokenize always start with an ENCODING token
352 which specifies the encoding used to decode the file. This token is
353 used to encode the output of untokenize back to bytes.

363
Georg Brandl52b92cc2008-05-25 09:43:03 +0000364- Issue #2282: io.TextIOWrapper was not overriding seekable() from
365 io.IOBase.
Ka-Ping Yeeddaa7062008-03-17 20:35:15 +0000366
Georg Brandl52b92cc2008-05-25 09:43:03 +0000367- Issue #2115: Important speedup in setting __slot__ attributes. Also
368 prevent a possible crash: an Abstract Base Class would try to access
369 a slot on a registered virtual subclass.
Christian Heimesa156e092008-02-16 07:38:31 +0000370
Georg Brandl52b92cc2008-05-25 09:43:03 +0000371- Fixed repr() and str() of complex numbers with infinity or nan as
372 real or imaginary part.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000374- Clear all free list during a gc.collect() of the highest generation
375 in order to allow pymalloc to free more arenas. Python may give back
376 memory to the OS earlier.
Christian Heimesa156e092008-02-16 07:38:31 +0000377
Georg Brandl52b92cc2008-05-25 09:43:03 +0000378- Issue #2045: Fix an infinite recursion triggered when printing a
379 subclass of collections.defaultdict, if its default_factory is set
380 to a bound method.
Christian Heimesa156e092008-02-16 07:38:31 +0000381
382- Fixed a minor memory leak in dictobject.c. The content of the free
383 list was not freed on interpreter shutdown.
384
Georg Brandl52b92cc2008-05-25 09:43:03 +0000385- Limit free list of method and builtin function objects to 256
386 entries each.
Christian Heimesa156e092008-02-16 07:38:31 +0000387
Georg Brandl52b92cc2008-05-25 09:43:03 +0000388- Patch #1953: Added ``sys._compact_freelists()`` and the C API
389 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000390 to compact the internal free lists of pre-allocted ints and floats.
391
392- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000393 Python expected the return type int but the fork familie returns
394 pi_t.
Christian Heimesa156e092008-02-16 07:38:31 +0000395
Georg Brandl52b92cc2008-05-25 09:43:03 +0000396- Issue #1678380: Fix a bug that identifies 0j and -0j when they
397 appear in the same code unit.
Christian Heimesa156e092008-02-16 07:38:31 +0000398
Georg Brandl52b92cc2008-05-25 09:43:03 +0000399- Issue #2025: Added tuple.count() and tuple.index() methods to comply
400 with the collections.Sequence API.
Raymond Hettinger65baa342008-02-07 00:41:02 +0000401
Georg Brandl52b92cc2008-05-25 09:43:03 +0000402- Fixed multiple reinitialization of the Python interpreter. The small
403 int list in longobject.c has caused a seg fault during the third
404 finalization.
Christian Heimesdfc12ed2008-01-31 15:16:38 +0000405
Georg Brandl52b92cc2008-05-25 09:43:03 +0000406- Issue #1973: bytes.fromhex('') raised SystemError.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000412- map() no longer accepts None for the first argument. Use zip()
413 instead.
Raymond Hettinger1dfde1d2008-01-22 23:25:35 +0000414
Facundo Batista2336bdd2008-01-19 19:12:01 +0000415- Issue #1769: Now int("- 1") is not allowed any more.
416
Georg Brandl52b92cc2008-05-25 09:43:03 +0000417- Object/longobject.c: long(float('nan')) raises an OverflowError

Georg Brandl52b92cc2008-05-25 09:43:03 +0000420- Issue #1762972: __file__ points to the source file instead of the
421 pyc/pyo file if the py file exists.
Christian Heimes3b06e532008-01-07 20:12:44 +0000422
Guido van Rossumab078dd2008-01-06 00:09:11 +0000423- Issue #1393: object_richcompare() returns NotImplemented instead of
424 False if the objects aren't equal, to give the other side a chance.
425
Guido van Rossume239b002008-01-06 00:44:20 +0000426- Issue #1692: Interpreter was not displaying location of SyntaxError.
Kurt B. Kaiser43b15092008-01-05 04:32:22 +0000427
Georg Brandl52b92cc2008-05-25 09:43:03 +0000428- Improve some exception messages when Windows fails to load an
429 extension module. Now we get for example '%1 is not a valid Win32
430 application' instead of 'error code 193'. Also use Unicode strings
431 to deal with non-English locales.
Amaury Forgeot d'Arcbccd63c2008-01-04 01:21:27 +0000432
Georg Brandl52b92cc2008-05-25 09:43:03 +0000433- Issue #1587: Added instancemethod wrapper for PyCFunctions. The
434 Python C API has gained a new type *PyInstanceMethod_Type* and the
435 functions *PyInstanceMethod_Check(o)*, *PyInstanceMethod_New(func)*
436 and *PyInstanceMethod_Function(im)*.
Christian Heimesa3534a62007-12-11 19:56:40 +0000437
Georg Brandl52b92cc2008-05-25 09:43:03 +0000438- Constants gc.DEBUG_OBJECT and gc.DEBUG_INSTANCE have been removed
439 from the gc module; gc.DEBUG_COLLECTABLE or gc.DEBUG_UNCOLLECTABLE
440 are now enough to print the corresponding list of objects considered
441 by the garbage collector.
Amaury Forgeot d'Arcad8dcd52007-12-10 23:58:35 +0000442
Georg Brandl52b92cc2008-05-25 09:43:03 +0000443- Issue #1573: Improper use of the keyword-only syntax makes the
444 parser crash.
Christian Heimesbc873412007-12-08 22:11:32 +0000445
Georg Brandl52b92cc2008-05-25 09:43:03 +0000446- Issue #1564: The set implementation should special-case PyUnicode

453
Guido van Rossumea6775b2008-02-21 20:16:31 +0000454- Bug #1713: posixpath.ismount() claims symlink to a mountpoint is a
455 mountpoint.
Christian Heimes7131fd92008-02-19 14:21:46 +0000456
Georg Brandl52b92cc2008-05-25 09:43:03 +0000457- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
458 the first chunk fed to the decoder started with a BOM, but was
459 longer than 3 bytes.
Christian Heimes7131fd92008-02-19 14:21:46 +0000460

Georg Brandl52b92cc2008-05-25 09:43:03 +0000481- Created new UserDict class in collections module. This one inherits
482 from and complies with the MutableMapping ABC. Also, moved
483 UserString and UserList to the collections module. The
484 MutableUserString class was removed.
Raymond Hettinger48b8b662008-02-05 01:53:00 +0000485
Guido van Rossumea6775b2008-02-21 20:16:31 +0000486- Removed UserDict.DictMixin. Replaced all its uses with

520-----------------
521
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000522- str8 now has the same construction signature as bytes.
523
Georg Brandl52b92cc2008-05-25 09:43:03 +0000524- Comparisons between str and str8 now return False/True for ==/!=.
525 sqlite3 returns str8 when recreating on object from it's __conform__
526 value. The struct module returns str8 for all string-related
527 formats. This was true before this change, but becomes more
528 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000529
Georg Brandl52b92cc2008-05-25 09:43:03 +0000530- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
531 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000532
533- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
534
535- Changed `__file__` and `co_filename` to unicode. The path names are decoded
536 with `Py_FileSystemDefaultEncoding` and a new API method
537 `PyUnicode_DecodeFSDefault(char*)` was added.
538
Georg Brandl52b92cc2008-05-25 09:43:03 +0000539- io.open() and _fileio.FileIO have grown a new argument closefd. A
540 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000541
Georg Brandl52b92cc2008-05-25 09:43:03 +0000542- Added a new option -b to issues warnings (-bb for errors) about
543 certain operations between bytes/buffer and str like str(b'') and
544 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000545
Georg Brandl52b92cc2008-05-25 09:43:03 +0000546- The standards streams sys.stdin, stdout and stderr may be None when
547 the when the C runtime library returns an invalid file descriptor
548 for the streams (fileno(stdin) < 0). For now this happens only for
549 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000550
Christian Heimesbce52be2007-11-17 19:08:41 +0000551- Added PCbuild9 directory for VS 2008.
552
Georg Brandl52b92cc2008-05-25 09:43:03 +0000553- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
554 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000555
Georg Brandl52b92cc2008-05-25 09:43:03 +0000556- Unbound methods are gone for good. ClassObject.method returns an
557 ordinary function object, instance.method still returns a bound
558 method object. The API of bound methods is cleaned up, too. The
559 im_class attribute is removed and im_func + im_self are renamed to
560 __func__ and __self__. The factory PyMethod_New takes only func and
561 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000562
Georg Brandl52b92cc2008-05-25 09:43:03 +0000563- intobject.h is no longer included by Python.h. The remains were
564 moved to longobject.h. It still exists to define several aliases

Georg Brandl52b92cc2008-05-25 09:43:03 +0000577- When loading an external file using testfile(), the passed-in
578 encoding argument was being ignored if __loader__ is defined and
579 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000580
Georg Brandl52b92cc2008-05-25 09:43:03 +0000581- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
582 been removed in favor of the tempfile module.

Neal Norwitz4886cc32006-08-21 17:06:07 +0000594
595Core and Builtins
596-----------------
597
Martin v. Löwis47383402007-08-15 07:32:56 +0000598- PEP 3131: Support non-ASCII identifiers.
599
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000600- PEP 3120: Change default encoding to UTF-8.
601
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000602- PEP 3123: Use proper C inheritance for PyObject.
603
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000604- Removed the __oct__ and __hex__ special methods and added a bin()
605 builtin function.
606
Georg Brandl52b92cc2008-05-25 09:43:03 +0000607- PEP 3127: octal literals now start with "0o". Old-style octal
608 literals are invalid. There are binary literals with a prefix of
609 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000610
Guido van Rossume7ba4952007-06-06 23:52:48 +0000611- None, True, False are now keywords.
612
Guido van Rossum29478ef2007-05-29 00:39:44 +0000613- PEP 3119: isinstance() and issubclass() can be overridden.
614
Guido van Rossumebe3e162007-05-17 18:20:34 +0000615- Remove BaseException.message.
616
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000617- Remove tuple parameter unpacking (PEP 3113).
618
Georg Brandl52b92cc2008-05-25 09:43:03 +0000619- Remove the f_restricted attribute from frames. This naturally leads
620 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000621
Georg Brandl52b92cc2008-05-25 09:43:03 +0000622- PEP 3132 was accepted. That means that you can do ``a, *b =
623 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000624
Georg Brandl52b92cc2008-05-25 09:43:03 +0000625- range() now returns an iterator rather than a list. Floats are not
626 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000627
Nick Coghlan650f0d02007-04-15 12:05:43 +0000628- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000629 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000630
Guido van Rossume27dc722007-03-27 22:37:34 +0000631- By default, != returns the opposite of ==, unless the latter returns
632 NotImplemented.
633
Georg Brandl52b92cc2008-05-25 09:43:03 +0000634- Patch #1680961: sys.exitfunc has been removed and replaced with a
635 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000636
Georg Brandl801dd732007-03-18 20:18:31 +0000637- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000638 keyword arg in the class statement, which can now use the full
639 syntax of a parameter list. Also, the metaclass can implement a
640 __prepare__ function which will be called to create the dictionary
641 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000642
Georg Brandl428f0642007-03-18 18:35:15 +0000643- The long-deprecated argument "pend" of PyFloat_FromString() has been
644 removed.
645
Georg Brandle32b4222007-03-10 22:13:27 +0000646- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000647 its argument, if it exists. If not, it will work like before. This
648 allows customizing the output of dir() in the presence of a
649 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000650
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000651- Removed support for __members__ and __methods__.
652
Georg Brandle32b4222007-03-10 22:13:27 +0000653- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000654
Georg Brandle32b4222007-03-10 22:13:27 +0000655- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000656 functionality formerly known as raw_input(); the name raw_input() is
657 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000658
Georg Brandl52b92cc2008-05-25 09:43:03 +0000659- Classes listed in an 'except' clause must inherit from
660 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000661
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000662- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000663 and .keys(), .items(), .values() return dict views, which behave
664 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000665
Guido van Rossum8b545362007-02-09 23:52:14 +0000666- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000667 'softspace' attribute of files is now gone (since print() doesn't
668 use it). A side effect of this change is that you can get
669 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +0000670
671 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000672 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +0000673
674 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +0000675
Brett Cannon398db8b2007-01-29 23:44:37 +0000676- PEP 3102: keyword-only arguments.
677
Georg Brandl52b92cc2008-05-25 09:43:03 +0000678- Int/Long unification is complete. The 'long' built-in type and
679 literals with trailing 'L' or 'l' have been removed. Performance
680 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000681
682- 'except E, V' must now be spelled as 'except E as V' and deletes V
683 at the end of the except clause; V must be a simple name.
684
Neal Norwitzc1505362006-12-28 06:47:50 +0000685- Added function annotations per PEP 3107.
686
Georg Brandl52b92cc2008-05-25 09:43:03 +0000687- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +0000688
689 >>> def f(x):
690 ... def inc():
691 ... nonlocal x
692 ... x += 1
693 ... return x
694 ... return inc
695 ...
696 >>> inc = f(0)
697 >>> inc()
698 1
699 >>> inc()
700 2
701
Georg Brandl66a796e2006-12-19 20:50:34 +0000702- Moved intern() to sys.intern().
703
704- exec is now a function.
705
706- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000707
Neal Norwitz4886cc32006-08-21 17:06:07 +0000708- Classic classes are a thing of the past. All classes are new style.
709
710- Exceptions *must* derive from BaseException.
711
712- Integer division always returns a float. The -Q option is no more.
713 All the following are gone:
714 * PyNumber_Divide and PyNumber_InPlaceDivide
715 * __div__, __rdiv__, and __idiv__
716 * nb_divide, nb_inplace_divide
717 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
718 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
719 if we want to re-use __div__ and friends. If we do, it will make
720 it harder to write code for both 2.x and 3.x.)
721
722- 'as' and 'with' are keywords.
723
724- Absolute import is the default behavior for 'import foo' etc.
725
Georg Brandl52b92cc2008-05-25 09:43:03 +0000726- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000727
Georg Brandl52b92cc2008-05-25 09:43:03 +0000728- Removed these Python builtins: apply(), callable(), coerce(),
729 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +0000730
Georg Brandl52b92cc2008-05-25 09:43:03 +0000731- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000732
Georg Brandl52b92cc2008-05-25 09:43:03 +0000733- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000734
735- Remove C API support for restricted execution.
736
Guido van Rossumcf1be882007-08-30 22:07:17 +0000737- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +0000738 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +0000739 sequences of unequal length -- it now stops after the shortest one
740 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000741
Georg Brandl52b92cc2008-05-25 09:43:03 +0000742- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000743
744- Added class decorators per PEP 3129.
