Guido van Rossumdc21db32008-04-07 18:37:41 +0000300- "make install" is now an alias for "make altinstall", to prevent
Georg Brandl52b92cc2008-05-25 09:43:03 +0000301 accidentally overwriting a Python 2.x installation. Use "make
302 fullinstall" to force Python 3.0 to be installed as "python".

314-----------------
315
316- Bug #2301: Don't try decoding the source code into the original
317 encoding for syntax errors.
318
Martin v. Löwis92fab752008-03-08 10:40:41 +0000319Extension Modules
320-----------------
321
Neal Norwitz6cf49cf2008-03-24 06:22:57 +0000322- The dl module was removed, use the ctypes module instead.
323
Martin v. Löwis92fab752008-03-08 10:40:41 +0000324- Use wchar_t functions in _locale module.

327-------
328
Georg Brandl52b92cc2008-05-25 09:43:03 +0000329- The class distutils.commands.build_py.build_py_2to3 can be used as a
330 build_py replacement to automatically run 2to3 on modules that are
331 going to be installed.
Martin v. Löwis73a22f02008-03-22 00:35:10 +0000332
Guido van Rossumf4169812008-03-17 22:56:06 +0000333- A new pickle protocol (protocol 3) is added with explicit support
334 for bytes. This is the default protocol. It intentionally cannot
335 be unpickled by Python 2.x.
336
337- When a pickle written by Python 2.x contains an (8-bit) str
338 instance, this is now decoded to a (Unicode) str instance. The
339 encoding used to do this defaults to ASCII, but can be overridden
340 via two new keyword arguments to the Unpickler class. Previously
341 this would create bytes instances, which is usually wrong: str
342 instances are often used to pickle attribute names etc., and text is
343 more common than binary data anyway.
344
Martin v. Löwis071ef772008-03-08 11:24:24 +0000345- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000346 system doesn't support CODESET and LANG isn't set or doesn't allow
347 deduction of an encoding.
Martin v. Löwis071ef772008-03-08 11:24:24 +0000348
Georg Brandl52b92cc2008-05-25 09:43:03 +0000349- Issue #1202: zlib.crc32 and zlib.adler32 now return an unsigned
350 value.
Gregory P. Smith425136b2008-03-17 20:45:21 +0000351
Georg Brandl52b92cc2008-05-25 09:43:03 +0000352- Issue #719888: Updated tokenize to use a bytes API. generate_tokens
353 has been renamed tokenize and now works with bytes rather than
354 strings. A new detect_encoding function has been added for
355 determining source file encoding according to PEP-0263. Token
356 sequences returned by tokenize always start with an ENCODING token
357 which specifies the encoding used to decode the file. This token is
358 used to encode the output of untokenize back to bytes.

368
Georg Brandl52b92cc2008-05-25 09:43:03 +0000369- Issue #2282: io.TextIOWrapper was not overriding seekable() from
370 io.IOBase.
Ka-Ping Yeeddaa7062008-03-17 20:35:15 +0000371
Georg Brandl52b92cc2008-05-25 09:43:03 +0000372- Issue #2115: Important speedup in setting __slot__ attributes. Also
373 prevent a possible crash: an Abstract Base Class would try to access
374 a slot on a registered virtual subclass.
Christian Heimesa156e092008-02-16 07:38:31 +0000375
Georg Brandl52b92cc2008-05-25 09:43:03 +0000376- Fixed repr() and str() of complex numbers with infinity or nan as
377 real or imaginary part.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000379- Clear all free list during a gc.collect() of the highest generation
380 in order to allow pymalloc to free more arenas. Python may give back
381 memory to the OS earlier.
Christian Heimesa156e092008-02-16 07:38:31 +0000382
Georg Brandl52b92cc2008-05-25 09:43:03 +0000383- Issue #2045: Fix an infinite recursion triggered when printing a

385 to a bound method.
Christian Heimesa156e092008-02-16 07:38:31 +0000386
387- Fixed a minor memory leak in dictobject.c. The content of the free
388 list was not freed on interpreter shutdown.
389
Georg Brandl52b92cc2008-05-25 09:43:03 +0000390- Limit free list of method and builtin function objects to 256
391 entries each.
Christian Heimesa156e092008-02-16 07:38:31 +0000392
Georg Brandl52b92cc2008-05-25 09:43:03 +0000393- Patch #1953: Added ``sys._compact_freelists()`` and the C API
394 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000395 to compact the internal free lists of pre-allocted ints and floats.
396
397- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000398 Python expected the return type int but the fork familie returns
399 pi_t.
Christian Heimesa156e092008-02-16 07:38:31 +0000400
Georg Brandl52b92cc2008-05-25 09:43:03 +0000401- Issue #1678380: Fix a bug that identifies 0j and -0j when they
402 appear in the same code unit.
Christian Heimesa156e092008-02-16 07:38:31 +0000403
Georg Brandl52b92cc2008-05-25 09:43:03 +0000404- Issue #2025: Added tuple.count() and tuple.index() methods to comply
405 with the collections.Sequence API.
Raymond Hettinger65baa342008-02-07 00:41:02 +0000406
Georg Brandl52b92cc2008-05-25 09:43:03 +0000407- Fixed multiple reinitialization of the Python interpreter. The small
408 int list in longobject.c has caused a seg fault during the third
409 finalization.
Christian Heimesdfc12ed2008-01-31 15:16:38 +0000410
Georg Brandl52b92cc2008-05-25 09:43:03 +0000411- Issue #1973: bytes.fromhex('') raised SystemError.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000425- Issue #1762972: __file__ points to the source file instead of the
426 pyc/pyo file if the py file exists.
Christian Heimes3b06e532008-01-07 20:12:44 +0000427
Guido van Rossumab078dd2008-01-06 00:09:11 +0000428- Issue #1393: object_richcompare() returns NotImplemented instead of
429 False if the objects aren't equal, to give the other side a chance.
430
Guido van Rossume239b002008-01-06 00:44:20 +0000431- Issue #1692: Interpreter was not displaying location of SyntaxError.
Kurt B. Kaiser43b15092008-01-05 04:32:22 +0000432
Georg Brandl52b92cc2008-05-25 09:43:03 +0000433- Improve some exception messages when Windows fails to load an
434 extension module. Now we get for example '%1 is not a valid Win32
435 application' instead of 'error code 193'. Also use Unicode strings
436 to deal with non-English locales.
Amaury Forgeot d'Arcbccd63c2008-01-04 01:21:27 +0000437
Georg Brandl52b92cc2008-05-25 09:43:03 +0000438- Issue #1587: Added instancemethod wrapper for PyCFunctions. The
439 Python C API has gained a new type *PyInstanceMethod_Type* and the
440 functions *PyInstanceMethod_Check(o)*, *PyInstanceMethod_New(func)*
441 and *PyInstanceMethod_Function(im)*.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000443- Constants gc.DEBUG_OBJECT and gc.DEBUG_INSTANCE have been removed
444 from the gc module; gc.DEBUG_COLLECTABLE or gc.DEBUG_UNCOLLECTABLE
445 are now enough to print the corresponding list of objects considered
446 by the garbage collector.
Amaury Forgeot d'Arcad8dcd52007-12-10 23:58:35 +0000447
Georg Brandl52b92cc2008-05-25 09:43:03 +0000448- Issue #1573: Improper use of the keyword-only syntax makes the
449 parser crash.

460 mountpoint.
Christian Heimes7131fd92008-02-19 14:21:46 +0000461
Georg Brandl52b92cc2008-05-25 09:43:03 +0000462- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
463 the first chunk fed to the decoder started with a BOM, but was
464 longer than 3 bytes.
Christian Heimes7131fd92008-02-19 14:21:46 +0000465

525-----------------
526
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000527- str8 now has the same construction signature as bytes.
528
Georg Brandl52b92cc2008-05-25 09:43:03 +0000529- Comparisons between str and str8 now return False/True for ==/!=.
530 sqlite3 returns str8 when recreating on object from it's __conform__
531 value. The struct module returns str8 for all string-related
532 formats. This was true before this change, but becomes more
533 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000534
Georg Brandl52b92cc2008-05-25 09:43:03 +0000535- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
536 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000537
538- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
539
540- Changed `__file__` and `co_filename` to unicode. The path names are decoded
541 with `Py_FileSystemDefaultEncoding` and a new API method
542 `PyUnicode_DecodeFSDefault(char*)` was added.
543
Georg Brandl52b92cc2008-05-25 09:43:03 +0000544- io.open() and _fileio.FileIO have grown a new argument closefd. A
545 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000546
Georg Brandl52b92cc2008-05-25 09:43:03 +0000547- Added a new option -b to issues warnings (-bb for errors) about
548 certain operations between bytes/buffer and str like str(b'') and
549 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000550
Georg Brandl52b92cc2008-05-25 09:43:03 +0000551- The standards streams sys.stdin, stdout and stderr may be None when
552 the when the C runtime library returns an invalid file descriptor
553 for the streams (fileno(stdin) < 0). For now this happens only for
554 Windows GUI apps and scripts started with `pythonw.exe`.

Christian Heimesbce52be2007-11-17 19:08:41 +0000556- Added PCbuild9 directory for VS 2008.
557
Georg Brandl52b92cc2008-05-25 09:43:03 +0000558- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
559 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000560
Georg Brandl52b92cc2008-05-25 09:43:03 +0000561- Unbound methods are gone for good. ClassObject.method returns an
562 ordinary function object, instance.method still returns a bound
563 method object. The API of bound methods is cleaned up, too. The
564 im_class attribute is removed and im_func + im_self are renamed to
565 __func__ and __self__. The factory PyMethod_New takes only func and

Georg Brandl52b92cc2008-05-25 09:43:03 +0000568- intobject.h is no longer included by Python.h. The remains were
569 moved to longobject.h. It still exists to define several aliases
570 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000571
Christian Heimesa37d4c62007-12-04 23:02:19 +0000572- Removed sys.maxint, use sys.maxsize instead.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000582- When loading an external file using testfile(), the passed-in
583 encoding argument was being ignored if __loader__ is defined and
584 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000585
Georg Brandl52b92cc2008-05-25 09:43:03 +0000586- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
587 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000588

Neal Norwitz4886cc32006-08-21 17:06:07 +0000599
600Core and Builtins
601-----------------
602
Martin v. Löwis47383402007-08-15 07:32:56 +0000603- PEP 3131: Support non-ASCII identifiers.
604
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000605- PEP 3120: Change default encoding to UTF-8.
606
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000607- PEP 3123: Use proper C inheritance for PyObject.
608
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000609- Removed the __oct__ and __hex__ special methods and added a bin()
610 builtin function.
611
Georg Brandl52b92cc2008-05-25 09:43:03 +0000612- PEP 3127: octal literals now start with "0o". Old-style octal
613 literals are invalid. There are binary literals with a prefix of
614 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000615
Guido van Rossume7ba4952007-06-06 23:52:48 +0000616- None, True, False are now keywords.
617
Guido van Rossum29478ef2007-05-29 00:39:44 +0000618- PEP 3119: isinstance() and issubclass() can be overridden.
619
Guido van Rossumebe3e162007-05-17 18:20:34 +0000620- Remove BaseException.message.
621
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000622- Remove tuple parameter unpacking (PEP 3113).
623
Georg Brandl52b92cc2008-05-25 09:43:03 +0000624- Remove the f_restricted attribute from frames. This naturally leads
625 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000626
Georg Brandl52b92cc2008-05-25 09:43:03 +0000627- PEP 3132 was accepted. That means that you can do ``a, *b =
628 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000629
Georg Brandl52b92cc2008-05-25 09:43:03 +0000630- range() now returns an iterator rather than a list. Floats are not
631 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000632
Nick Coghlan650f0d02007-04-15 12:05:43 +0000633- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000634 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000635
Guido van Rossume27dc722007-03-27 22:37:34 +0000636- By default, != returns the opposite of ==, unless the latter returns
637 NotImplemented.
638
Georg Brandl52b92cc2008-05-25 09:43:03 +0000639- Patch #1680961: sys.exitfunc has been removed and replaced with a
640 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000641
Georg Brandl801dd732007-03-18 20:18:31 +0000642- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000643 keyword arg in the class statement, which can now use the full
644 syntax of a parameter list. Also, the metaclass can implement a
645 __prepare__ function which will be called to create the dictionary
646 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000647
Georg Brandl428f0642007-03-18 18:35:15 +0000648- The long-deprecated argument "pend" of PyFloat_FromString() has been
649 removed.
650
Georg Brandle32b4222007-03-10 22:13:27 +0000651- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000652 its argument, if it exists. If not, it will work like before. This
653 allows customizing the output of dir() in the presence of a
654 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000655
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000656- Removed support for __members__ and __methods__.
657
Georg Brandle32b4222007-03-10 22:13:27 +0000658- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000659
Georg Brandle32b4222007-03-10 22:13:27 +0000660- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000661 functionality formerly known as raw_input(); the name raw_input() is
662 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000663
Georg Brandl52b92cc2008-05-25 09:43:03 +0000664- Classes listed in an 'except' clause must inherit from
665 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000666
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000667- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000668 and .keys(), .items(), .values() return dict views, which behave
669 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000670
Guido van Rossum8b545362007-02-09 23:52:14 +0000671- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000672 'softspace' attribute of files is now gone (since print() doesn't
673 use it). A side effect of this change is that you can get
674 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +0000675
676 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000677 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +0000678
679 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +0000680
Brett Cannon398db8b2007-01-29 23:44:37 +0000681- PEP 3102: keyword-only arguments.
682
Georg Brandl52b92cc2008-05-25 09:43:03 +0000683- Int/Long unification is complete. The 'long' built-in type and
684 literals with trailing 'L' or 'l' have been removed. Performance
685 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000686
687- 'except E, V' must now be spelled as 'except E as V' and deletes V
688 at the end of the except clause; V must be a simple name.
689
Neal Norwitzc1505362006-12-28 06:47:50 +0000690- Added function annotations per PEP 3107.
691
Georg Brandl52b92cc2008-05-25 09:43:03 +0000692- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +0000693
694 >>> def f(x):
695 ... def inc():
696 ... nonlocal x
697 ... x += 1
698 ... return x
699 ... return inc
700 ...
701 >>> inc = f(0)
702 >>> inc()
703 1
704 >>> inc()
705 2
706
Georg Brandl66a796e2006-12-19 20:50:34 +0000707- Moved intern() to sys.intern().
708
709- exec is now a function.
710
711- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000712
Neal Norwitz4886cc32006-08-21 17:06:07 +0000713- Classic classes are a thing of the past. All classes are new style.
714
715- Exceptions *must* derive from BaseException.
716
717- Integer division always returns a float. The -Q option is no more.
718 All the following are gone:
719 * PyNumber_Divide and PyNumber_InPlaceDivide
720 * __div__, __rdiv__, and __idiv__
721 * nb_divide, nb_inplace_divide
722 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
723 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
724 if we want to re-use __div__ and friends. If we do, it will make
725 it harder to write code for both 2.x and 3.x.)
726
727- 'as' and 'with' are keywords.
728
729- Absolute import is the default behavior for 'import foo' etc.
730
Georg Brandl52b92cc2008-05-25 09:43:03 +0000731- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000732
Georg Brandl52b92cc2008-05-25 09:43:03 +0000733- Removed these Python builtins: apply(), callable(), coerce(),
734 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +0000735
Georg Brandl52b92cc2008-05-25 09:43:03 +0000736- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000737
Georg Brandl52b92cc2008-05-25 09:43:03 +0000738- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000739
740- Remove C API support for restricted execution.
741
Guido van Rossumcf1be882007-08-30 22:07:17 +0000742- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +0000743 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +0000744 sequences of unequal length -- it now stops after the shortest one
745 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000746
Georg Brandl52b92cc2008-05-25 09:43:03 +0000747- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000748
749- Added class decorators per PEP 3129.
