613 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
614
Eric Smith741191f2009-05-06 13:08:15 +0000615- Issue #3382: float.__format__, complex.__format__, and %-formatting
616 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
617 affects nan -> NAN and inf -> INF.
618
Mark Hammond5a607a32009-05-06 08:04:54 +0000619- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
620 in all operations, including splitdrive, split, etc. splitunc() now issues
621 a PendingDeprecation warning.
622
Eric Smith63376222009-05-05 14:04:18 +0000623- Issue #5920: For float.__format__, change the behavior with the
624 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
625 to be like 'g' but with at least one decimal point and with a
626 default precision of 12. Previously, the behavior the same but with
627 a default precision of 6. This more closely matches str(), and
628 reduces surprises when adding alignment flags to the empty
629 presentation type. This also affects the new complex.__format__ in
630 the same way.
631
Martin v. Löwis011e8422009-05-05 04:43:17 +0000632- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
633
R. David Murrayb18500d2009-05-04 22:59:07 +0000634- Issue #5890: in subclasses of 'property' the __doc__ attribute was
635 shadowed by classtype's, even if it was None. property now
636 inserts the __doc__ into the subclass instance __dict__.
637
Antoine Pitrou244651a2009-05-04 18:56:13 +0000638- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
639 sequences. Patch by Nick Barnes and Victor Stinner.
640
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000641- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000642
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000643- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
644 received a new method, detach(). detach() disconnects the underlying stream
645 from the buffer or text IO and returns it.
646
Mark Dickinson33841c32009-05-01 15:37:04 +0000647- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
648 floats with absolute value over 1e50. Also remove length
649 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
650 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000651
Eric Smith741191f2009-05-06 13:08:15 +0000652- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000653 format(complex(1, 2./3), '.5') now produces a sensible result.
654
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000655- Issue #5864: Fix empty format code formatting for floats so that it
656 never gives more than the requested number of significant digits.
657
Eric Smith6dc46f52009-04-27 20:39:49 +0000658- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
659 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
660

662
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000663- Issue #4971: Fix titlecase for characters that are their own
664 titlecase, but not their own uppercase.
665
Benjamin Peterson193152c2009-04-25 01:08:45 +0000666- Issue #5283: Setting __class__ in __del__ caused a segfault.
667
Mark Dickinsonad476da2009-04-23 19:14:16 +0000668- Issue #5816: complex(repr(z)) now recovers z exactly, even when
669 z involves nans, infs or negative zeros.
670
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000671- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000672
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000673- Issue #1869 (and many duplicates): make round(x, n) correctly
674 rounded for a float x, by using the decimal <-> binary conversions
675 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
676 consistently agrees with format(x, '.2f').
677
Benjamin Petersonae937c02009-04-18 20:54:08 +0000678- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
679 some builtin types.
680
Eric Smith0923d1d2009-04-16 20:16:10 +0000681- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
682
Eric Smith35e84722009-04-16 20:21:28 +0000683- Issue #5515: str.format() type 'n' combined with commas and leading
684 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000685
686- Implement PEP 378, Format Specifier for Thousands Separator, for
687 floats.
688
Mark Dickinson3370cce2009-04-17 22:40:53 +0000689- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000690 1e11, not 1e12. This avoids printing 13 significant digits in
691 situations where only 12 of them are correct. Example problem
692 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
693 long time.)
694
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000695- Issue #1580: On most platforms, use a 'short' float repr: for a
696 finite float x, repr(x) now outputs a string based on the shortest
697 sequence of decimal digits that rounds to x. Previous behaviour was
698 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000699 Another minor difference is that the new repr switches to
700 exponential notation at 1e16 instead of the previous 1e17; this
701 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000702
703 There's a new sys attribute sys.float_repr_style, which takes
704 the value 'short' to indicate that we're using short float repr,
705 and 'legacy' if the short float repr isn't available for one
706 reason or another.
707
708 The float repr change involves incorporating David Gay's 'perfect
709 rounding' code into the Python core (it's in Python/dtoa.c). As a
710 secondary consequence, all string-to-float and float-to-string
711 conversions (including all float formatting operations) will be
712 correctly rounded on these platforms.
713
714 See issue 1580 discussions for details of platforms for which
715 this change does not apply.
716
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000717- Issue #5759: float() didn't call __float__ on str subclasses.
718
Georg Brandlabc38772009-04-12 15:51:51 +0000719- The string.maketrans() function is deprecated; there is a new static method
720 maketrans() on the bytes and bytearray classes. This removes confusion about
721 the types string.maketrans() is supposed to work with, and mirrors the
722 methods available on the str class.
723
R. David Murraydc6da8a2009-04-09 22:16:43 +0000724- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

728 to avoid compiler warnings.
729
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000730- Issue #3739: The unicode-internal encoder now reports the number of characters

887
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000888- Issue #4688: Add a heuristic so that tuples and dicts containing only
889 untrackable objects are not tracked by the garbage collector. This can
890 reduce the size of collections and therefore the garbage collection overhead
891 on long-running programs, depending on their particular use of datatypes.

1012 rotating the object pointer by 4 bits to the right.
1013
Mark Dickinson87ec0852009-02-09 17:15:59 +00001014- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1015 it now forces its argument to double before testing for infinity.
1016
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001017- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1025 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001026
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001027- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001028 were suppressing all exceptions. These include list() and bytearray().
1029
Mark Dickinson1124e712009-01-28 21:25:58 +00001030- Issue #4707: round(x, n) now returns an integer if x is an integer.
1031 Previously it returned a float.
1032
Antoine Pitroub52ec782009-01-25 16:34:23 +00001033- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1034 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1035 evaluation loop is compiled with a new dispatch mechanism which gives
1036 speedups of up to 20%, depending on the system, on various benchmarks.
1037
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001038- Issue #4874: Most builtin decoders now reject unicode input.

1044
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001045- Issue #4838: When a module is deallocated, free the memory backing the
1046 optional module state data.
1047
Mark Dickinson8055afd2009-01-17 10:04:45 +00001048- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1049 type to (void *).
1050
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001051- Issue #4935: The overflow checking code in the expandtabs() method common
1052 to str, bytes and bytearray could be optimized away by the compiler, letting
1053 the interpreter segfault instead of raising an error.
1054
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001055- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1056 __next__ method.
1057
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001058- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1059 function no longer attempt to call the __long__ slot to convert an object
1060 to an integer. Only the __int__ and __trunc__ slots are examined.
1061
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001062- Issue #4893: Use NT threading on CE.
1063
Martin v. Löwisec59d042009-01-12 07:59:10 +00001064- Issue #4915: Port sysmodule to Windows CE.
1065
Antoine Pitrouab868312009-01-10 15:40:25 +00001066- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1067 common cases are optimized thanks to a dedicated fast path and a moderate
1068 amount of loop unrolling.
1069
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001070- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1071 collecting the oldest generation) so that allocating lots of objects without
1072 destroying them does not show quadratic performance. Based on a proposal by
1073 Martin von Löwis at
1074 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1075
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001076- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001077 having been closed (for instance, a read() call could return some
1078 previously buffered data). Patch by Dmitry Vasiliev.
1079
Antoine Pitrou05608432009-01-09 18:53:14 +00001080- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1081 flag to work properly. Furthermore, when specifying -u, the text stdout
1082 and stderr streams have line-by-line buffering enabled (the default being
1083 to buffer arbitrary chunks of data).
1084
Raymond Hettinger35631532009-01-09 03:58:09 +00001085- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1086 instead of ints (reducing its size from 4 to 8 times thereby reducing
1087 Python's overall memory).
1088
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001089- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1090 an existing .py counterpart, override the co_filename attributes of all
1091 code objects if the original filename is obsolete (which can happen if the
1092 file has been renamed, moved, or if it is accessed through different paths).
1093 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1094
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001095- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1096 one byte. Also fixes the meaning of len() so that it returns the number of
1097 items, rather than the size in bytes.
1098
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001099- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1100
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001101- Issue #4747: When the terminal does not use utf-8, executing a script with
1102 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1103
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001104- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001105 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001106
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001107- Issue #3680: Reference cycles created through a dict, set or deque iterator
1108 did not get collected.
1109
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001110- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1111 where the tp_hash and tp_dict slots are both NULL.
1112
Georg Brandlccc47b62008-12-28 11:44:14 +00001113- Issue #4759: None is now allowed as the first argument of
1114 bytearray.translate(). It was always allowed for bytes.translate().
1115
Skip Montanaro80072cb2008-12-23 03:51:14 +00001116- Added test case to ensure attempts to read from a file opened for writing
1117 fail.
1118
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001119- Issue #3106: Speedup some comparisons (str/str and int/int).

1122 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1123
Antoine Pitrou621601a2008-12-17 23:18:19 +00001124- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1125 print elapsed times, not only when some objects are uncollectable /
1126 unreachable. Original patch by Neil Schemenauer.
1127
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001128- Issue #3439: Add a bit_length method to int.
1129
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001130- Issue #2173: When getting device encoding, check that return value of
1131 nl_langinfo is not the empty string. This was causing silent build
1132 failures on OS X.
1133
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001134- Issue #4597: Fixed several opcodes that weren't always propagating
1135 exceptions.
1136
1137- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001138 context manager returns a value that cannot be converted to a bool.
1139
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001140- Issue #4445: Replace "sizeof(PyBytesObject)" with
1141 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1142 bytes instances. On a typical machine this saves 3 bytes of memory
1143 (on average) per allocation of a bytes instance.
1144
Christian Heimesa872de52008-12-05 08:26:55 +00001145- Issue #4533: File read operation was dreadfully slow due to a slowly
1146 growing read buffer. Fixed by using the same growth rate algorithm as
1147 Python 2.x.
1148
Antoine Pitrou5504e892008-12-06 21:27:53 +00001149- Issue #4509: Various issues surrounding resize of bytearray objects to
1150 which there are buffer exports (e.g. memoryview instances).
1151
Georg Brandlf9734072008-12-07 15:30:06 +00001152- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1153 method on file objects with closefd=False. The file descriptor is still
1154 kept open but the file object behaves like a closed file. The ``FileIO``
1155 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001156
Antoine Pitroubc420402008-12-07 20:14:49 +00001157- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001164- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1165 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1166 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1167 of using the replace error handler in PyUnicode_DecodeUTF8().
