Georg Brandl52b92cc2008-05-25 09:43:03 +0000192- Issue #2221: Corrected a SystemError "error return without exception
193 set", when the code executed by exec() raises an exception, and
194 sys.stdout.flush() also raises an error.
Amaury Forgeot d'Arc7fedbe52008-04-10 21:03:09 +0000195
Georg Brandl52b92cc2008-05-25 09:43:03 +0000196- Bug #2565: The repr() of type objects now calls them 'class', not
197 'type' - whether they are builtin types or not.
Martin v. Löwis250ad612008-04-07 05:43:42 +0000198
Martin v. Löwis790465f2008-04-05 20:41:37 +0000199- The command line processing was converted to pass Unicode strings

Guido van Rossumf4169812008-03-17 22:56:06 +0000264- A new pickle protocol (protocol 3) is added with explicit support
265 for bytes. This is the default protocol. It intentionally cannot
266 be unpickled by Python 2.x.
267
268- When a pickle written by Python 2.x contains an (8-bit) str
269 instance, this is now decoded to a (Unicode) str instance. The
270 encoding used to do this defaults to ASCII, but can be overridden
271 via two new keyword arguments to the Unpickler class. Previously
272 this would create bytes instances, which is usually wrong: str
273 instances are often used to pickle attribute names etc., and text is
274 more common than binary data anyway.
275
Martin v. Löwis071ef772008-03-08 11:24:24 +0000276- Default to ASCII as the locale.getpreferredencoding, if the POSIX
Georg Brandl52b92cc2008-05-25 09:43:03 +0000277 system doesn't support CODESET and LANG isn't set or doesn't allow
278 deduction of an encoding.

284 has been renamed tokenize and now works with bytes rather than
285 strings. A new detect_encoding function has been added for
286 determining source file encoding according to PEP-0263. Token
287 sequences returned by tokenize always start with an ENCODING token
288 which specifies the encoding used to decode the file. This token is
289 used to encode the output of untokenize back to bytes.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000307- Fixed repr() and str() of complex numbers with infinity or nan as
308 real or imaginary part.
Christian Heimesa156e092008-02-16 07:38:31 +0000309
Georg Brandl52b92cc2008-05-25 09:43:03 +0000310- Clear all free list during a gc.collect() of the highest generation
311 in order to allow pymalloc to free more arenas. Python may give back
312 memory to the OS earlier.
Christian Heimesa156e092008-02-16 07:38:31 +0000313
Georg Brandl52b92cc2008-05-25 09:43:03 +0000314- Issue #2045: Fix an infinite recursion triggered when printing a

Christian Heimesa156e092008-02-16 07:38:31 +0000317
318- Fixed a minor memory leak in dictobject.c. The content of the free
319 list was not freed on interpreter shutdown.
320

Georg Brandl52b92cc2008-05-25 09:43:03 +0000324- Patch #1953: Added ``sys._compact_freelists()`` and the C API
325 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimesa156e092008-02-16 07:38:31 +0000326 to compact the internal free lists of pre-allocted ints and floats.
327
328- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
Georg Brandl52b92cc2008-05-25 09:43:03 +0000329 Python expected the return type int but the fork familie returns
330 pi_t.
Christian Heimesa156e092008-02-16 07:38:31 +0000331
Georg Brandl52b92cc2008-05-25 09:43:03 +0000332- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl52b92cc2008-05-25 09:43:03 +0000338- Fixed multiple reinitialization of the Python interpreter. The small
339 int list in longobject.c has caused a seg fault during the third
340 finalization.
Christian Heimesdfc12ed2008-01-31 15:16:38 +0000341

Kurt B. Kaiser43b15092008-01-05 04:32:22 +0000363
Georg Brandl52b92cc2008-05-25 09:43:03 +0000364- Improve some exception messages when Windows fails to load an
365 extension module. Now we get for example '%1 is not a valid Win32
366 application' instead of 'error code 193'. Also use Unicode strings
367 to deal with non-English locales.
Amaury Forgeot d'Arcbccd63c2008-01-04 01:21:27 +0000368
Georg Brandl52b92cc2008-05-25 09:43:03 +0000369- Issue #1587: Added instancemethod wrapper for PyCFunctions. The
370 Python C API has gained a new type *PyInstanceMethod_Type* and the
371 functions *PyInstanceMethod_Check(o)*, *PyInstanceMethod_New(func)*
372 and *PyInstanceMethod_Function(im)*.
Christian Heimesa3534a62007-12-11 19:56:40 +0000373
Georg Brandl52b92cc2008-05-25 09:43:03 +0000374- Constants gc.DEBUG_OBJECT and gc.DEBUG_INSTANCE have been removed
375 from the gc module; gc.DEBUG_COLLECTABLE or gc.DEBUG_UNCOLLECTABLE
376 are now enough to print the corresponding list of objects considered
377 by the garbage collector.
Amaury Forgeot d'Arcad8dcd52007-12-10 23:58:35 +0000378
Georg Brandl52b92cc2008-05-25 09:43:03 +0000379- Issue #1573: Improper use of the keyword-only syntax makes the

391 mountpoint.
Christian Heimes7131fd92008-02-19 14:21:46 +0000392
Georg Brandl52b92cc2008-05-25 09:43:03 +0000393- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
394 the first chunk fed to the decoder started with a BOM, but was
395 longer than 3 bytes.

Guido van Rossum40d20bc2007-10-22 00:09:51 +0000455Core and Builtins
456-----------------
457
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000458- str8 now has the same construction signature as bytes.
459
Georg Brandl52b92cc2008-05-25 09:43:03 +0000460- Comparisons between str and str8 now return False/True for ==/!=.
461 sqlite3 returns str8 when recreating on object from it's __conform__
462 value. The struct module returns str8 for all string-related
463 formats. This was true before this change, but becomes more
464 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000465
Georg Brandl52b92cc2008-05-25 09:43:03 +0000466- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
467 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000468
469- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
470
471- Changed `__file__` and `co_filename` to unicode. The path names are decoded
472 with `Py_FileSystemDefaultEncoding` and a new API method
473 `PyUnicode_DecodeFSDefault(char*)` was added.
474
Georg Brandl52b92cc2008-05-25 09:43:03 +0000475- io.open() and _fileio.FileIO have grown a new argument closefd. A
476 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000477
Georg Brandl52b92cc2008-05-25 09:43:03 +0000478- Added a new option -b to issues warnings (-bb for errors) about
479 certain operations between bytes/buffer and str like str(b'') and
480 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000481
Georg Brandl52b92cc2008-05-25 09:43:03 +0000482- The standards streams sys.stdin, stdout and stderr may be None when
483 the when the C runtime library returns an invalid file descriptor
484 for the streams (fileno(stdin) < 0). For now this happens only for
485 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000486
Christian Heimesbce52be2007-11-17 19:08:41 +0000487- Added PCbuild9 directory for VS 2008.
488
Georg Brandl52b92cc2008-05-25 09:43:03 +0000489- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
490 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000491
Georg Brandl52b92cc2008-05-25 09:43:03 +0000492- Unbound methods are gone for good. ClassObject.method returns an
493 ordinary function object, instance.method still returns a bound
494 method object. The API of bound methods is cleaned up, too. The
495 im_class attribute is removed and im_func + im_self are renamed to
496 __func__ and __self__. The factory PyMethod_New takes only func and
497 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000498
Georg Brandl52b92cc2008-05-25 09:43:03 +0000499- intobject.h is no longer included by Python.h. The remains were
500 moved to longobject.h. It still exists to define several aliases
501 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000502
Christian Heimesa37d4c62007-12-04 23:02:19 +0000503- Removed sys.maxint, use sys.maxsize instead.

511-------
512
Georg Brandl52b92cc2008-05-25 09:43:03 +0000513- When loading an external file using testfile(), the passed-in
514 encoding argument was being ignored if __loader__ is defined and
515 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000516
Georg Brandl52b92cc2008-05-25 09:43:03 +0000517- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
518 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000519
Christian Heimesc9543e42007-11-28 08:28:28 +0000520- Removed the 'new' module.
521
Georg Brandl52b92cc2008-05-25 09:43:03 +0000522- Removed all types from the 'types' module that are easily accessable
523 through builtins.

Guido van Rossumcd16bf62007-06-13 18:07:49 +0000540- Removed the __oct__ and __hex__ special methods and added a bin()
541 builtin function.
542
Georg Brandl52b92cc2008-05-25 09:43:03 +0000543- PEP 3127: octal literals now start with "0o". Old-style octal
544 literals are invalid. There are binary literals with a prefix of
545 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000546
Guido van Rossume7ba4952007-06-06 23:52:48 +0000547- None, True, False are now keywords.

554
Georg Brandl52b92cc2008-05-25 09:43:03 +0000555- Remove the f_restricted attribute from frames. This naturally leads
556 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000557
Georg Brandl52b92cc2008-05-25 09:43:03 +0000558- PEP 3132 was accepted. That means that you can do ``a, *b =
559 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000560
Georg Brandl52b92cc2008-05-25 09:43:03 +0000561- range() now returns an iterator rather than a list. Floats are not
562 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000563
Nick Coghlan650f0d02007-04-15 12:05:43 +0000564- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000565 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000566
Guido van Rossume27dc722007-03-27 22:37:34 +0000567- By default, != returns the opposite of ==, unless the latter returns
568 NotImplemented.
569
Georg Brandl52b92cc2008-05-25 09:43:03 +0000570- Patch #1680961: sys.exitfunc has been removed and replaced with a
571 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000572
Georg Brandl801dd732007-03-18 20:18:31 +0000573- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000574 keyword arg in the class statement, which can now use the full
575 syntax of a parameter list. Also, the metaclass can implement a
576 __prepare__ function which will be called to create the dictionary
577 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000578
Georg Brandl428f0642007-03-18 18:35:15 +0000579- The long-deprecated argument "pend" of PyFloat_FromString() has been
580 removed.
581
Georg Brandle32b4222007-03-10 22:13:27 +0000582- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000583 its argument, if it exists. If not, it will work like before. This
584 allows customizing the output of dir() in the presence of a
585 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000586
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000587- Removed support for __members__ and __methods__.
588
Georg Brandle32b4222007-03-10 22:13:27 +0000589- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000590
Georg Brandle32b4222007-03-10 22:13:27 +0000591- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000592 functionality formerly known as raw_input(); the name raw_input() is
593 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +0000594
Georg Brandl52b92cc2008-05-25 09:43:03 +0000595- Classes listed in an 'except' clause must inherit from
596 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000597
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000598- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000599 and .keys(), .items(), .values() return dict views, which behave
600 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000601
Guido van Rossum8b545362007-02-09 23:52:14 +0000602- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +0000603 'softspace' attribute of files is now gone (since print() doesn't
604 use it). A side effect of this change is that you can get
605 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +0000606
607 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000608 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +0000609
610 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +0000611
Brett Cannon398db8b2007-01-29 23:44:37 +0000612- PEP 3102: keyword-only arguments.
613
Georg Brandl52b92cc2008-05-25 09:43:03 +0000614- Int/Long unification is complete. The 'long' built-in type and
615 literals with trailing 'L' or 'l' have been removed. Performance
616 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000617
618- 'except E, V' must now be spelled as 'except E as V' and deletes V
619 at the end of the except clause; V must be a simple name.
620
Neal Norwitzc1505362006-12-28 06:47:50 +0000621- Added function annotations per PEP 3107.
622
Georg Brandl52b92cc2008-05-25 09:43:03 +0000623- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +0000624
625 >>> def f(x):
626 ... def inc():
627 ... nonlocal x
628 ... x += 1
629 ... return x
630 ... return inc
631 ...
632 >>> inc = f(0)
633 >>> inc()
634 1
635 >>> inc()
636 2
637
Georg Brandl66a796e2006-12-19 20:50:34 +0000638- Moved intern() to sys.intern().
639
640- exec is now a function.
641
642- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000643
Neal Norwitz4886cc32006-08-21 17:06:07 +0000644- Classic classes are a thing of the past. All classes are new style.
645
646- Exceptions *must* derive from BaseException.
647
648- Integer division always returns a float. The -Q option is no more.
649 All the following are gone:
650 * PyNumber_Divide and PyNumber_InPlaceDivide
651 * __div__, __rdiv__, and __idiv__
652 * nb_divide, nb_inplace_divide
653 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
654 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
655 if we want to re-use __div__ and friends. If we do, it will make
656 it harder to write code for both 2.x and 3.x.)
657
658- 'as' and 'with' are keywords.
659
660- Absolute import is the default behavior for 'import foo' etc.
661
Georg Brandl52b92cc2008-05-25 09:43:03 +0000662- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000663
Georg Brandl52b92cc2008-05-25 09:43:03 +0000664- Removed these Python builtins: apply(), callable(), coerce(),
665 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +0000666
Georg Brandl52b92cc2008-05-25 09:43:03 +0000667- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +0000668
Georg Brandl52b92cc2008-05-25 09:43:03 +0000669- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000670
671- Remove C API support for restricted execution.
672
Guido van Rossumcf1be882007-08-30 22:07:17 +0000673- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +0000674 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +0000675 sequences of unequal length -- it now stops after the shortest one
676 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000677
Georg Brandl52b92cc2008-05-25 09:43:03 +0000678- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000679
680- Added class decorators per PEP 3129.
