300-----------------
301
302- Bug #2301: Don't try decoding the source code into the original
303 encoding for syntax errors.

Martin v. Löwis92fab752008-03-08 10:40:41 +0000305Extension Modules
306-----------------
307
Neal Norwitz6cf49cf2008-03-24 06:22:57 +0000308- The dl module was removed, use the ctypes module instead.
309
Martin v. Löwis92fab752008-03-08 10:40:41 +0000310- Use wchar_t functions in _locale module.

313-------
314
Georg Brandl52b92cc2008-05-25 09:43:03 +0000315- The class distutils.commands.build_py.build_py_2to3 can be used as a
316 build_py replacement to automatically run 2to3 on modules that are
317 going to be installed.
Martin v. Löwis73a22f02008-03-22 00:35:10 +0000318
Guido van Rossumf4169812008-03-17 22:56:06 +0000319- A new pickle protocol (protocol 3) is added with explicit support
320 for bytes. This is the default protocol. It intentionally cannot
321 be unpickled by Python 2.x.
322
323- When a pickle written by Python 2.x contains an (8-bit) str
324 instance, this is now decoded to a (Unicode) str instance. The
325 encoding used to do this defaults to ASCII, but can be overridden
326 via two new keyword arguments to the Unpickler class. Previously
327 this would create bytes instances, which is usually wrong: str
328 instances are often used to pickle attribute names etc., and text is
329 more common than binary data anyway.
330
Martin v. Löwis071ef772008-03-08 11:24:24 +0000331- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000332 system doesn't support CODESET and LANG isn't set or doesn't allow
333 deduction of an encoding.
Martin v. Löwis071ef772008-03-08 11:24:24 +0000334
Georg Brandl52b92cc2008-05-25 09:43:03 +0000335- Issue #1202: zlib.crc32 and zlib.adler32 now return an unsigned
336 value.
Gregory P. Smith425136b2008-03-17 20:45:21 +0000337
Georg Brandl52b92cc2008-05-25 09:43:03 +0000338- Issue #719888: Updated tokenize to use a bytes API. generate_tokens
339 has been renamed tokenize and now works with bytes rather than
340 strings. A new detect_encoding function has been added for
341 determining source file encoding according to PEP-0263. Token
342 sequences returned by tokenize always start with an ENCODING token
343 which specifies the encoding used to decode the file. This token is
344 used to encode the output of untokenize back to bytes.

354
Georg Brandl52b92cc2008-05-25 09:43:03 +0000355- Issue #2282: io.TextIOWrapper was not overriding seekable() from
356 io.IOBase.
Ka-Ping Yeeddaa7062008-03-17 20:35:15 +0000357
Georg Brandl52b92cc2008-05-25 09:43:03 +0000358- Issue #2115: Important speedup in setting __slot__ attributes. Also
359 prevent a possible crash: an Abstract Base Class would try to access
360 a slot on a registered virtual subclass.
Christian Heimesa156e092008-02-16 07:38:31 +0000361
Georg Brandl52b92cc2008-05-25 09:43:03 +0000362- Fixed repr() and str() of complex numbers with infinity or nan as

367 memory to the OS earlier.
Christian Heimesa156e092008-02-16 07:38:31 +0000368
Georg Brandl52b92cc2008-05-25 09:43:03 +0000369- Issue #2045: Fix an infinite recursion triggered when printing a

371 to a bound method.
Christian Heimesa156e092008-02-16 07:38:31 +0000372
373- Fixed a minor memory leak in dictobject.c. The content of the free
374 list was not freed on interpreter shutdown.
375
Georg Brandl52b92cc2008-05-25 09:43:03 +0000376- Limit free list of method and builtin function objects to 256
377 entries each.
Christian Heimesa156e092008-02-16 07:38:31 +0000378
Georg Brandl52b92cc2008-05-25 09:43:03 +0000379- Patch #1953: Added ``sys._compact_freelists()`` and the C API
380 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000381 to compact the internal free lists of pre-allocted ints and floats.
382
383- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000384 Python expected the return type int but the fork familie returns
385 pi_t.
Christian Heimesa156e092008-02-16 07:38:31 +0000386
Georg Brandl52b92cc2008-05-25 09:43:03 +0000387- Issue #1678380: Fix a bug that identifies 0j and -0j when they
388 appear in the same code unit.
Christian Heimesa156e092008-02-16 07:38:31 +0000389
Georg Brandl52b92cc2008-05-25 09:43:03 +0000390- Issue #2025: Added tuple.count() and tuple.index() methods to comply
391 with the collections.Sequence API.
Raymond Hettinger65baa342008-02-07 00:41:02 +0000392
Georg Brandl52b92cc2008-05-25 09:43:03 +0000393- Fixed multiple reinitialization of the Python interpreter. The small
394 int list in longobject.c has caused a seg fault during the third
395 finalization.
Christian Heimesdfc12ed2008-01-31 15:16:38 +0000396

Christian Heimes3b06e532008-01-07 20:12:44 +0000413
Guido van Rossumab078dd2008-01-06 00:09:11 +0000414- Issue #1393: object_richcompare() returns NotImplemented instead of
415 False if the objects aren't equal, to give the other side a chance.
416
Guido van Rossume239b002008-01-06 00:44:20 +0000417- Issue #1692: Interpreter was not displaying location of SyntaxError.
Kurt B. Kaiser43b15092008-01-05 04:32:22 +0000418
Georg Brandl52b92cc2008-05-25 09:43:03 +0000419- Improve some exception messages when Windows fails to load an
420 extension module. Now we get for example '%1 is not a valid Win32
421 application' instead of 'error code 193'. Also use Unicode strings
422 to deal with non-English locales.
Amaury Forgeot d'Arcbccd63c2008-01-04 01:21:27 +0000423
Georg Brandl52b92cc2008-05-25 09:43:03 +0000424- Issue #1587: Added instancemethod wrapper for PyCFunctions. The
425 Python C API has gained a new type *PyInstanceMethod_Type* and the
426 functions *PyInstanceMethod_Check(o)*, *PyInstanceMethod_New(func)*
427 and *PyInstanceMethod_Function(im)*.
Christian Heimesa3534a62007-12-11 19:56:40 +0000428
Georg Brandl52b92cc2008-05-25 09:43:03 +0000429- Constants gc.DEBUG_OBJECT and gc.DEBUG_INSTANCE have been removed
430 from the gc module; gc.DEBUG_COLLECTABLE or gc.DEBUG_UNCOLLECTABLE
431 are now enough to print the corresponding list of objects considered
432 by the garbage collector.
Amaury Forgeot d'Arcad8dcd52007-12-10 23:58:35 +0000433
Georg Brandl52b92cc2008-05-25 09:43:03 +0000434- Issue #1573: Improper use of the keyword-only syntax makes the
435 parser crash.
Christian Heimesbc873412007-12-08 22:11:32 +0000436
Georg Brandl52b92cc2008-05-25 09:43:03 +0000437- Issue #1564: The set implementation should special-case PyUnicode
438 instead of PyString.

446 mountpoint.
Christian Heimes7131fd92008-02-19 14:21:46 +0000447
Georg Brandl52b92cc2008-05-25 09:43:03 +0000448- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
449 the first chunk fed to the decoder started with a BOM, but was
450 longer than 3 bytes.
Christian Heimes7131fd92008-02-19 14:21:46 +0000451

Georg Brandl52b92cc2008-05-25 09:43:03 +0000472- Created new UserDict class in collections module. This one inherits
473 from and complies with the MutableMapping ABC. Also, moved
474 UserString and UserList to the collections module. The
475 MutableUserString class was removed.
Raymond Hettinger48b8b662008-02-05 01:53:00 +0000476
Guido van Rossumea6775b2008-02-21 20:16:31 +0000477- Removed UserDict.DictMixin. Replaced all its uses with

511-----------------
512
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000513- str8 now has the same construction signature as bytes.
514
Georg Brandl52b92cc2008-05-25 09:43:03 +0000515- Comparisons between str and str8 now return False/True for ==/!=.
516 sqlite3 returns str8 when recreating on object from it's __conform__
517 value. The struct module returns str8 for all string-related
518 formats. This was true before this change, but becomes more
519 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000520
Georg Brandl52b92cc2008-05-25 09:43:03 +0000521- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
522 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000523
524- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
525
526- Changed `__file__` and `co_filename` to unicode. The path names are decoded
527 with `Py_FileSystemDefaultEncoding` and a new API method
528 `PyUnicode_DecodeFSDefault(char*)` was added.
529
Georg Brandl52b92cc2008-05-25 09:43:03 +0000530- io.open() and _fileio.FileIO have grown a new argument closefd. A
531 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000532
Georg Brandl52b92cc2008-05-25 09:43:03 +0000533- Added a new option -b to issues warnings (-bb for errors) about
534 certain operations between bytes/buffer and str like str(b'') and
535 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000536
Georg Brandl52b92cc2008-05-25 09:43:03 +0000537- The standards streams sys.stdin, stdout and stderr may be None when
538 the when the C runtime library returns an invalid file descriptor
539 for the streams (fileno(stdin) < 0). For now this happens only for
540 Windows GUI apps and scripts started with `pythonw.exe`.

Christian Heimesbce52be2007-11-17 19:08:41 +0000542- Added PCbuild9 directory for VS 2008.
543
Georg Brandl52b92cc2008-05-25 09:43:03 +0000544- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
545 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000546
Georg Brandl52b92cc2008-05-25 09:43:03 +0000547- Unbound methods are gone for good. ClassObject.method returns an
548 ordinary function object, instance.method still returns a bound
549 method object. The API of bound methods is cleaned up, too. The
550 im_class attribute is removed and im_func + im_self are renamed to
551 __func__ and __self__. The factory PyMethod_New takes only func and
552 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000553
Georg Brandl52b92cc2008-05-25 09:43:03 +0000554- intobject.h is no longer included by Python.h. The remains were
555 moved to longobject.h. It still exists to define several aliases
556 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000557
Christian Heimesa37d4c62007-12-04 23:02:19 +0000558- Removed sys.maxint, use sys.maxsize instead.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000568- When loading an external file using testfile(), the passed-in
569 encoding argument was being ignored if __loader__ is defined and
570 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000571
Georg Brandl52b92cc2008-05-25 09:43:03 +0000572- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
573 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000574
Christian Heimesc9543e42007-11-28 08:28:28 +0000575- Removed the 'new' module.
576
Georg Brandl52b92cc2008-05-25 09:43:03 +0000577- Removed all types from the 'types' module that are easily accessable

Thomas Wouters4d70c3d2006-06-08 14:42:34 +0000583
Guido van Rossum4405cf32007-08-30 17:16:55 +0000584*Release date: 31-Aug-2007*
Neal Norwitz4886cc32006-08-21 17:06:07 +0000585
586Core and Builtins
587-----------------
588
Martin v. Löwis47383402007-08-15 07:32:56 +0000589- PEP 3131: Support non-ASCII identifiers.
590
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000591- PEP 3120: Change default encoding to UTF-8.
592
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000593- PEP 3123: Use proper C inheritance for PyObject.
594
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000595- Removed the __oct__ and __hex__ special methods and added a bin()
596 builtin function.
597
Georg Brandl52b92cc2008-05-25 09:43:03 +0000598- PEP 3127: octal literals now start with "0o". Old-style octal
599 literals are invalid. There are binary literals with a prefix of
600 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000601
Guido van Rossume7ba4952007-06-06 23:52:48 +0000602- None, True, False are now keywords.
603
Guido van Rossum29478ef2007-05-29 00:39:44 +0000604- PEP 3119: isinstance() and issubclass() can be overridden.
605
Guido van Rossumebe3e162007-05-17 18:20:34 +0000606- Remove BaseException.message.
607
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000608- Remove tuple parameter unpacking (PEP 3113).
609
Georg Brandl52b92cc2008-05-25 09:43:03 +0000610- Remove the f_restricted attribute from frames. This naturally leads
611 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000612
Georg Brandl52b92cc2008-05-25 09:43:03 +0000613- PEP 3132 was accepted. That means that you can do ``a, *b =
614 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000615
Georg Brandl52b92cc2008-05-25 09:43:03 +0000616- range() now returns an iterator rather than a list. Floats are not
617 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000618
Nick Coghlan650f0d02007-04-15 12:05:43 +0000619- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000620 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000621
Guido van Rossume27dc722007-03-27 22:37:34 +0000622- By default, != returns the opposite of ==, unless the latter returns
623 NotImplemented.
624
Georg Brandl52b92cc2008-05-25 09:43:03 +0000625- Patch #1680961: sys.exitfunc has been removed and replaced with a
626 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000627
Georg Brandl801dd732007-03-18 20:18:31 +0000628- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000629 keyword arg in the class statement, which can now use the full
630 syntax of a parameter list. Also, the metaclass can implement a
631 __prepare__ function which will be called to create the dictionary
632 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000633
Georg Brandl428f0642007-03-18 18:35:15 +0000634- The long-deprecated argument "pend" of PyFloat_FromString() has been
635 removed.
636
Georg Brandle32b4222007-03-10 22:13:27 +0000637- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000638 its argument, if it exists. If not, it will work like before. This
639 allows customizing the output of dir() in the presence of a
640 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000641
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000642- Removed support for __members__ and __methods__.
643
Georg Brandle32b4222007-03-10 22:13:27 +0000644- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000645
Georg Brandle32b4222007-03-10 22:13:27 +0000646- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000647 functionality formerly known as raw_input(); the name raw_input() is
648 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000649
Georg Brandl52b92cc2008-05-25 09:43:03 +0000650- Classes listed in an 'except' clause must inherit from
651 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000652
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000653- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000654 and .keys(), .items(), .values() return dict views, which behave
655 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000656
Guido van Rossum8b545362007-02-09 23:52:14 +0000657- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000658 'softspace' attribute of files is now gone (since print() doesn't
659 use it). A side effect of this change is that you can get
660 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +0000661
662 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000663 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +0000664
665 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +0000666
Brett Cannon398db8b2007-01-29 23:44:37 +0000667- PEP 3102: keyword-only arguments.
668
Georg Brandl52b92cc2008-05-25 09:43:03 +0000669- Int/Long unification is complete. The 'long' built-in type and
670 literals with trailing 'L' or 'l' have been removed. Performance
671 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000672
673- 'except E, V' must now be spelled as 'except E as V' and deletes V
674 at the end of the except clause; V must be a simple name.
675
Neal Norwitzc1505362006-12-28 06:47:50 +0000676- Added function annotations per PEP 3107.
677
Georg Brandl52b92cc2008-05-25 09:43:03 +0000678- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +0000679
680 >>> def f(x):
681 ... def inc():
682 ... nonlocal x
683 ... x += 1
684 ... return x
685 ... return inc
686 ...
687 >>> inc = f(0)
688 >>> inc()
689 1
690 >>> inc()
691 2
692
Georg Brandl66a796e2006-12-19 20:50:34 +0000693- Moved intern() to sys.intern().
694
695- exec is now a function.
696
697- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000698
Neal Norwitz4886cc32006-08-21 17:06:07 +0000699- Classic classes are a thing of the past. All classes are new style.
700
701- Exceptions *must* derive from BaseException.
702
703- Integer division always returns a float. The -Q option is no more.
704 All the following are gone:
705 * PyNumber_Divide and PyNumber_InPlaceDivide
706 * __div__, __rdiv__, and __idiv__
707 * nb_divide, nb_inplace_divide
708 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
709 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
710 if we want to re-use __div__ and friends. If we do, it will make
711 it harder to write code for both 2.x and 3.x.)
712
713- 'as' and 'with' are keywords.
714
715- Absolute import is the default behavior for 'import foo' etc.
716
Georg Brandl52b92cc2008-05-25 09:43:03 +0000717- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000718
Georg Brandl52b92cc2008-05-25 09:43:03 +0000719- Removed these Python builtins: apply(), callable(), coerce(),
720 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +0000721
Georg Brandl52b92cc2008-05-25 09:43:03 +0000722- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000723
Georg Brandl52b92cc2008-05-25 09:43:03 +0000724- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000725
726- Remove C API support for restricted execution.
727
Guido van Rossumcf1be882007-08-30 22:07:17 +0000728- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +0000729 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +0000730 sequences of unequal length -- it now stops after the shortest one
731 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000732
Georg Brandl52b92cc2008-05-25 09:43:03 +0000733- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000734
735- Added class decorators per PEP 3129.

739-----------------
740
Georg Brandl52b92cc2008-05-25 09:43:03 +0000741- Removed the imageop module. Obsolete long with its unit tests
742 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +0000743
Georg Brandl52b92cc2008-05-25 09:43:03 +0000744- Removed these attributes from the operator module: div, idiv,
745 __div__, __idiv__, isCallable, sequenceIncludes.
746
747- Removed these attributes from the sys module: exc_clear(), exc_type,
748 exc_value, exc_traceback.

Guido van Rossumd59da4b2007-05-22 18:11:13 +0000773
Georg Brandl52b92cc2008-05-25 09:43:03 +0000774- Removed xmlrpclib.SlowParser. It was based on xmllib.
