 | 320 |  | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 321 | - The class distutils.commands.build_py.build_py_2to3 can be used as a |

| Guido van Rossum | f416981 | 2008-03-17 22:56:06 +0000 | [diff] [blame] | 325 | - A new pickle protocol (protocol 3) is added with explicit support | 
 | 326 |   for bytes.  This is the default protocol.  It intentionally cannot | 
 | 327 |   be unpickled by Python 2.x. | 
 | 328 |  | 
 | 329 | - When a pickle written by Python 2.x contains an (8-bit) str | 
 | 330 |   instance, this is now decoded to a (Unicode) str instance.  The | 
 | 331 |   encoding used to do this defaults to ASCII, but can be overridden | 
 | 332 |   via two new keyword arguments to the Unpickler class.  Previously | 
 | 333 |   this would create bytes instances, which is usually wrong: str | 
 | 334 |   instances are often used to pickle attribute names etc., and text is | 
 | 335 |   more common than binary data anyway. |

| Martin v. Löwis | 071ef77 | 2008-03-08 11:24:24 +0000 | [diff] [blame] | 337 | - Default to ASCII as the locale.getpreferredencoding, if the POSIX |

| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 344 | - Issue #719888: Updated tokenize to use a bytes API.  generate_tokens | 
 | 345 |   has been renamed tokenize and now works with bytes rather than | 
 | 346 |   strings.  A new detect_encoding function has been added for | 
 | 347 |   determining source file encoding according to PEP-0263.  Token | 
 | 348 |   sequences returned by tokenize always start with an ENCODING token | 
 | 349 |   which specifies the encoding used to decode the file.  This token is | 
 | 350 |   used to encode the output of untokenize back to bytes. |

| Brett Cannon | 37f7e6e | 2007-10-26 05:42:09 +0000 | [diff] [blame] | 519 | - str8 now has the same construction signature as bytes. | 
 | 520 |  | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 521 | - Comparisons between str and str8 now return False/True for ==/!=. | 
 | 522 |   sqlite3 returns str8 when recreating on object from it's __conform__ | 
 | 523 |   value.  The struct module returns str8 for all string-related | 
 | 524 |   formats.  This was true before this change, but becomes more | 
 | 525 |   apparent thanks to string comparisons always being False. |

| Guido van Rossum | 40d20bc | 2007-10-22 00:09:51 +0000 | [diff] [blame] | 529 |  | 
 | 530 | - Fixed `imp.find_module()` to obey the -*- coding: -*- header. | 
 | 531 |  | 
 | 532 | - Changed `__file__` and `co_filename` to unicode. The path names are decoded | 
 | 533 |   with `Py_FileSystemDefaultEncoding` and a new API method  | 
 | 534 |   `PyUnicode_DecodeFSDefault(char*)` was added. | 
 | 535 |  | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 536 | - io.open() and _fileio.FileIO have grown a new argument closefd. A | 
 | 537 |   false value disables the closing of the file descriptor. |

| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 543 | - The standards streams sys.stdin, stdout and stderr may be None when | 
 | 544 |   the when the C runtime library returns an invalid file descriptor | 
 | 545 |   for the streams (fileno(stdin) < 0). For now this happens only for |

 | 549 |  | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 550 | - Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to |

| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 553 | - Unbound methods are gone for good. ClassObject.method returns an | 
 | 554 |   ordinary function object, instance.method still returns a bound | 
 | 555 |   method object.  The API of bound methods is cleaned up, too. The | 
 | 556 |   im_class attribute is removed and im_func + im_self are renamed to | 
 | 557 |   __func__ and __self__. The factory PyMethod_New takes only func and | 
 | 558 |   instance as argument. |

| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 560 | - intobject.h is no longer included by Python.h. The remains were | 
 | 561 |   moved to longobject.h. It still exists to define several aliases | 
 | 562 |   from PyInt_ to PyLong_ functions. |

 | 617 |   to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted(). |

| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 619 | - PEP 3132 was accepted. That means that you can do ``a, *b = | 
 | 620 |   range(5)`` to assign 0 to a and [1, 2, 3, 4] to b. | 
| Guido van Rossum | 0368b72 | 2007-05-11 16:50:42 +0000 | [diff] [blame] | 621 |  | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 622 | - range() now returns an iterator rather than a list.  Floats are not | 
 | 623 |   allowed.  xrange() is no longer defined. |

| Nick Coghlan | 650f0d0 | 2007-04-15 12:05:43 +0000 | [diff] [blame] | 625 | - Patch #1660500: hide iteration variable in list comps, add set comps | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 626 |   and use common code to handle compilation of iterative expressions. |

| Georg Brandl | 801dd73 | 2007-03-18 20:18:31 +0000 | [diff] [blame] | 634 | - PEP 3115: new metaclasses: the metaclass is now specified as a | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 635 |   keyword arg in the class statement, which can now use the full | 
 | 636 |   syntax of a parameter list. Also, the metaclass can implement a | 
 | 637 |   __prepare__ function which will be called to create the dictionary | 
 | 638 |   for the new class namespace. |

 | 642 |  | 
| Georg Brandl | e32b422 | 2007-03-10 22:13:27 +0000 | [diff] [blame] | 643 | - The dir() function has been extended to call the __dir__() method on | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 644 |   its argument, if it exists. If not, it will work like before. This | 
 | 645 |   allows customizing the output of dir() in the presence of a | 
 | 646 |   __getattr__(). |

| Georg Brandl | e32b422 | 2007-03-10 22:13:27 +0000 | [diff] [blame] | 652 | - input() became raw_input(): the name input() now implements the | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 653 |   functionality formerly known as raw_input(); the name raw_input() is |

| Guido van Rossum | cc2b016 | 2007-02-11 06:12:03 +0000 | [diff] [blame] | 659 | - PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone; |

| Guido van Rossum | 8b54536 | 2007-02-09 23:52:14 +0000 | [diff] [blame] | 663 | - PEP 3105: print is now a function.  Also (not in the PEP) the | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 664 |   'softspace' attribute of files is now gone (since print() doesn't | 
 | 665 |   use it).  A side effect of this change is that you can get | 
 | 666 |   incomplete output lines in interactive sessions: | 
| Guido van Rossum | 8b54536 | 2007-02-09 23:52:14 +0000 | [diff] [blame] | 667 |  |

| Brett Cannon | 398db8b | 2007-01-29 23:44:37 +0000 | [diff] [blame] | 673 | - PEP 3102: keyword-only arguments. | 
 | 674 |  | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 675 | - Int/Long unification is complete.  The 'long' built-in type and | 
 | 676 |   literals with trailing 'L' or 'l' have been removed.  Performance | 
 | 677 |   may be sub-optimal (haven't really benchmarked). | 
| Guido van Rossum | ab18684 | 2007-01-14 03:42:30 +0000 | [diff] [blame] | 678 |  | 
 | 679 | - 'except E, V' must now be spelled as 'except E as V' and deletes V |

 | 681 |  | 
| Neal Norwitz | c150536 | 2006-12-28 06:47:50 +0000 | [diff] [blame] | 682 | - Added function annotations per PEP 3107. |

| Neal Norwitz | 4886cc3 | 2006-08-21 17:06:07 +0000 | [diff] [blame] | 705 | - Classic classes are a thing of the past.  All classes are new style. | 
 | 706 |  | 
 | 707 | - Exceptions *must* derive from BaseException. | 
 | 708 |  | 
 | 709 | - Integer division always returns a float.  The -Q option is no more. | 
 | 710 |   All the following are gone: | 
 | 711 |    * PyNumber_Divide and PyNumber_InPlaceDivide | 
 | 712 |    * __div__, __rdiv__, and __idiv__ | 
 | 713 |    * nb_divide, nb_inplace_divide | 
 | 714 |    * operator.div, operator.idiv, operator.__div__, operator.__idiv__ | 
 | 715 |   (Only __truediv__ and __floordiv__ remain, not sure how to handle them | 
 | 716 |    if we want to re-use __div__ and friends.  If we do, it will make | 
 | 717 |    it harder to write code for both 2.x and 3.x.) | 
 | 718 |  | 
 | 719 | - 'as' and 'with' are keywords. |

| Guido van Rossum | cf1be88 | 2007-08-30 22:07:17 +0000 | [diff] [blame] | 734 | - zip(), map() and filter() now return iterators, behaving like their | 
| Georg Brandl | 52b92cc | 2008-05-25 09:43:03 +0000 | [diff] [blame] | 735 |   itertools counterparts.  This also affect map()'s behavior on | 
| Guido van Rossum | cf1be88 | 2007-08-30 22:07:17 +0000 | [diff] [blame] | 736 |   sequences of unequal length -- it now stops after the shortest one |
