Guido van Rossumdc21db32008-04-07 18:37:41 +0000313- "make install" is now an alias for "make altinstall", to prevent
Georg Brandl52b92cc2008-05-25 09:43:03 +0000314 accidentally overwriting a Python 2.x installation. Use "make

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

333-----------------
334
Neal Norwitz6cf49cf2008-03-24 06:22:57 +0000335- The dl module was removed, use the ctypes module instead.
336
Martin v. Löwis92fab752008-03-08 10:40:41 +0000337- Use wchar_t functions in _locale module.

341
Georg Brandl52b92cc2008-05-25 09:43:03 +0000342- The class distutils.commands.build_py.build_py_2to3 can be used as a
343 build_py replacement to automatically run 2to3 on modules that are
344 going to be installed.
Martin v. Löwis73a22f02008-03-22 00:35:10 +0000345
Guido van Rossumf4169812008-03-17 22:56:06 +0000346- A new pickle protocol (protocol 3) is added with explicit support
347 for bytes. This is the default protocol. It intentionally cannot
348 be unpickled by Python 2.x.
349
350- When a pickle written by Python 2.x contains an (8-bit) str
351 instance, this is now decoded to a (Unicode) str instance. The
352 encoding used to do this defaults to ASCII, but can be overridden
353 via two new keyword arguments to the Unpickler class. Previously
354 this would create bytes instances, which is usually wrong: str
355 instances are often used to pickle attribute names etc., and text is
356 more common than binary data anyway.
357
Martin v. Löwis071ef772008-03-08 11:24:24 +0000358- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000359 system doesn't support CODESET and LANG isn't set or doesn't allow
360 deduction of an encoding.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000362- Issue #1202: zlib.crc32 and zlib.adler32 now return an unsigned
363 value.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000365- Issue #719888: Updated tokenize to use a bytes API. generate_tokens
366 has been renamed tokenize and now works with bytes rather than
367 strings. A new detect_encoding function has been added for
368 determining source file encoding according to PEP-0263. Token
369 sequences returned by tokenize always start with an ENCODING token
370 which specifies the encoding used to decode the file. This token is
371 used to encode the output of untokenize back to bytes.

386 prevent a possible crash: an Abstract Base Class would try to access
387 a slot on a registered virtual subclass.
Christian Heimesa156e092008-02-16 07:38:31 +0000388

398 to a bound method.
Christian Heimesa156e092008-02-16 07:38:31 +0000399
400- Fixed a minor memory leak in dictobject.c. The content of the free
401 list was not freed on interpreter shutdown.
402
Georg Brandl52b92cc2008-05-25 09:43:03 +0000403- Limit free list of method and builtin function objects to 256
404 entries each.
Christian Heimesa156e092008-02-16 07:38:31 +0000405
Georg Brandl52b92cc2008-05-25 09:43:03 +0000406- Patch #1953: Added ``sys._compact_freelists()`` and the C API
407 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000408 to compact the internal free lists of pre-allocted ints and floats.
409
410- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000411 Python expected the return type int but the fork familie returns
412 pi_t.

415 appear in the same code unit.
Christian Heimesa156e092008-02-16 07:38:31 +0000416
Georg Brandl52b92cc2008-05-25 09:43:03 +0000417- Issue #2025: Added tuple.count() and tuple.index() methods to comply
418 with the collections.Sequence API.
Raymond Hettinger65baa342008-02-07 00:41:02 +0000419
Georg Brandl52b92cc2008-05-25 09:43:03 +0000420- Fixed multiple reinitialization of the Python interpreter. The small
421 int list in longobject.c has caused a seg fault during the third
422 finalization.
Christian Heimesdfc12ed2008-01-31 15:16:38 +0000423

Christian Heimes3b06e532008-01-07 20:12:44 +0000440
Guido van Rossumab078dd2008-01-06 00:09:11 +0000441- Issue #1393: object_richcompare() returns NotImplemented instead of
442 False if the objects aren't equal, to give the other side a chance.
443
Guido van Rossume239b002008-01-06 00:44:20 +0000444- Issue #1692: Interpreter was not displaying location of SyntaxError.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000446- Improve some exception messages when Windows fails to load an
447 extension module. Now we get for example '%1 is not a valid Win32
448 application' instead of 'error code 193'. Also use Unicode strings
449 to deal with non-English locales.

539
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000540- str8 now has the same construction signature as bytes.
541
Georg Brandl52b92cc2008-05-25 09:43:03 +0000542- Comparisons between str and str8 now return False/True for ==/!=.
543 sqlite3 returns str8 when recreating on object from it's __conform__
544 value. The struct module returns str8 for all string-related
545 formats. This was true before this change, but becomes more
546 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000547
Georg Brandl52b92cc2008-05-25 09:43:03 +0000548- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
549 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000550
551- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
552
553- Changed `__file__` and `co_filename` to unicode. The path names are decoded
554 with `Py_FileSystemDefaultEncoding` and a new API method
555 `PyUnicode_DecodeFSDefault(char*)` was added.
556
Georg Brandl52b92cc2008-05-25 09:43:03 +0000557- io.open() and _fileio.FileIO have grown a new argument closefd. A
558 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000559
Georg Brandl52b92cc2008-05-25 09:43:03 +0000560- Added a new option -b to issues warnings (-bb for errors) about
561 certain operations between bytes/buffer and str like str(b'') and
562 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000563
Georg Brandl52b92cc2008-05-25 09:43:03 +0000564- The standards streams sys.stdin, stdout and stderr may be None when
565 the when the C runtime library returns an invalid file descriptor
566 for the streams (fileno(stdin) < 0). For now this happens only for
567 Windows GUI apps and scripts started with `pythonw.exe`.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000571- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
572 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000573
Georg Brandl52b92cc2008-05-25 09:43:03 +0000574- Unbound methods are gone for good. ClassObject.method returns an
575 ordinary function object, instance.method still returns a bound
576 method object. The API of bound methods is cleaned up, too. The
577 im_class attribute is removed and im_func + im_self are renamed to
578 __func__ and __self__. The factory PyMethod_New takes only func and
579 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000580
Georg Brandl52b92cc2008-05-25 09:43:03 +0000581- intobject.h is no longer included by Python.h. The remains were
582 moved to longobject.h. It still exists to define several aliases
583 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000584
Christian Heimesa37d4c62007-12-04 23:02:19 +0000585- Removed sys.maxint, use sys.maxsize instead.

594
Georg Brandl52b92cc2008-05-25 09:43:03 +0000595- When loading an external file using testfile(), the passed-in
596 encoding argument was being ignored if __loader__ is defined and
597 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000598
Georg Brandl52b92cc2008-05-25 09:43:03 +0000599- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
600 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000601
Christian Heimesc9543e42007-11-28 08:28:28 +0000602- Removed the 'new' module.
603
Georg Brandl52b92cc2008-05-25 09:43:03 +0000604- Removed all types from the 'types' module that are easily accessable

Neal Norwitz4886cc32006-08-21 17:06:07 +0000612
613Core and Builtins
614-----------------
615
Martin v. Löwis47383402007-08-15 07:32:56 +0000616- PEP 3131: Support non-ASCII identifiers.
617
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000618- PEP 3120: Change default encoding to UTF-8.
619
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000620- PEP 3123: Use proper C inheritance for PyObject.
621
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000622- Removed the __oct__ and __hex__ special methods and added a bin()
623 builtin function.
624
Georg Brandl52b92cc2008-05-25 09:43:03 +0000625- PEP 3127: octal literals now start with "0o". Old-style octal
626 literals are invalid. There are binary literals with a prefix of
627 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000628
Guido van Rossume7ba4952007-06-06 23:52:48 +0000629- None, True, False are now keywords.
630
Guido van Rossum29478ef2007-05-29 00:39:44 +0000631- PEP 3119: isinstance() and issubclass() can be overridden.
632
Guido van Rossumebe3e162007-05-17 18:20:34 +0000633- Remove BaseException.message.
634
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000635- Remove tuple parameter unpacking (PEP 3113).
636
Georg Brandl52b92cc2008-05-25 09:43:03 +0000637- Remove the f_restricted attribute from frames. This naturally leads
638 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000639
Georg Brandl52b92cc2008-05-25 09:43:03 +0000640- PEP 3132 was accepted. That means that you can do ``a, *b =
641 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000642
Georg Brandl52b92cc2008-05-25 09:43:03 +0000643- range() now returns an iterator rather than a list. Floats are not
644 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000645
Nick Coghlan650f0d02007-04-15 12:05:43 +0000646- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000647 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000648
Guido van Rossume27dc722007-03-27 22:37:34 +0000649- By default, != returns the opposite of ==, unless the latter returns
650 NotImplemented.
651
Georg Brandl52b92cc2008-05-25 09:43:03 +0000652- Patch #1680961: sys.exitfunc has been removed and replaced with a
653 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000654
Georg Brandl801dd732007-03-18 20:18:31 +0000655- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000656 keyword arg in the class statement, which can now use the full
657 syntax of a parameter list. Also, the metaclass can implement a
658 __prepare__ function which will be called to create the dictionary
659 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000660
Georg Brandl428f0642007-03-18 18:35:15 +0000661- The long-deprecated argument "pend" of PyFloat_FromString() has been
662 removed.
663
Georg Brandle32b4222007-03-10 22:13:27 +0000664- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000665 its argument, if it exists. If not, it will work like before. This
666 allows customizing the output of dir() in the presence of a
667 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000668
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000669- Removed support for __members__ and __methods__.
670
Georg Brandle32b4222007-03-10 22:13:27 +0000671- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000672
Georg Brandle32b4222007-03-10 22:13:27 +0000673- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000674 functionality formerly known as raw_input(); the name raw_input() is
675 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000676
Georg Brandl52b92cc2008-05-25 09:43:03 +0000677- Classes listed in an 'except' clause must inherit from
678 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000679
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000680- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000681 and .keys(), .items(), .values() return dict views, which behave
682 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000683
Guido van Rossum8b545362007-02-09 23:52:14 +0000684- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000685 'softspace' attribute of files is now gone (since print() doesn't
686 use it). A side effect of this change is that you can get
687 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +0000688
689 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000690 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +0000691
692 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +0000693
Brett Cannon398db8b2007-01-29 23:44:37 +0000694- PEP 3102: keyword-only arguments.
695
Georg Brandl52b92cc2008-05-25 09:43:03 +0000696- Int/Long unification is complete. The 'long' built-in type and
697 literals with trailing 'L' or 'l' have been removed. Performance
698 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000699
700- 'except E, V' must now be spelled as 'except E as V' and deletes V
701 at the end of the except clause; V must be a simple name.
702
Neal Norwitzc1505362006-12-28 06:47:50 +0000703- Added function annotations per PEP 3107.
704
Georg Brandl52b92cc2008-05-25 09:43:03 +0000705- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +0000706
707 >>> def f(x):
708 ... def inc():
709 ... nonlocal x
710 ... x += 1
711 ... return x
712 ... return inc
713 ...
714 >>> inc = f(0)
715 >>> inc()
716 1
717 >>> inc()
718 2
719
Georg Brandl66a796e2006-12-19 20:50:34 +0000720- Moved intern() to sys.intern().
721
722- exec is now a function.
723
724- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000725
Neal Norwitz4886cc32006-08-21 17:06:07 +0000726- Classic classes are a thing of the past. All classes are new style.
727
728- Exceptions *must* derive from BaseException.
729
730- Integer division always returns a float. The -Q option is no more.
731 All the following are gone:
732 * PyNumber_Divide and PyNumber_InPlaceDivide
733 * __div__, __rdiv__, and __idiv__
734 * nb_divide, nb_inplace_divide
735 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
736 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
737 if we want to re-use __div__ and friends. If we do, it will make
738 it harder to write code for both 2.x and 3.x.)
739
740- 'as' and 'with' are keywords.
741
742- Absolute import is the default behavior for 'import foo' etc.
743
Georg Brandl52b92cc2008-05-25 09:43:03 +0000744- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000745
Georg Brandl52b92cc2008-05-25 09:43:03 +0000746- Removed these Python builtins: apply(), callable(), coerce(),
747 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +0000748
Georg Brandl52b92cc2008-05-25 09:43:03 +0000749- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000750
Georg Brandl52b92cc2008-05-25 09:43:03 +0000751- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000752
753- Remove C API support for restricted execution.
754
Guido van Rossumcf1be882007-08-30 22:07:17 +0000755- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +0000756 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +0000757 sequences of unequal length -- it now stops after the shortest one
758 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000759
Georg Brandl52b92cc2008-05-25 09:43:03 +0000760- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000761
762- Added class decorators per PEP 3129.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000768- Removed the imageop module. Obsolete long with its unit tests
769 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +0000770
Georg Brandl52b92cc2008-05-25 09:43:03 +0000771- Removed these attributes from the operator module: div, idiv,

773
774- Removed these attributes from the sys module: exc_clear(), exc_type,
775 exc_value, exc_traceback.
