440 was locale aware; and (3) the interpretation of fromhex('-nan')

Mark Dickinson865e01a2009-05-07 16:37:01 +0000547- Issue #5914: Add new C API function PyOS_string_to_double, and
548 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
549
Eric Smith741191f2009-05-06 13:08:15 +0000550- Issue #3382: float.__format__, complex.__format__, and %-formatting
551 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
552 affects nan -> NAN and inf -> INF.
553
Mark Hammond5a607a32009-05-06 08:04:54 +0000554- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
555 in all operations, including splitdrive, split, etc. splitunc() now issues
556 a PendingDeprecation warning.
557
Eric Smith63376222009-05-05 14:04:18 +0000558- Issue #5920: For float.__format__, change the behavior with the
559 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
560 to be like 'g' but with at least one decimal point and with a
561 default precision of 12. Previously, the behavior the same but with
562 a default precision of 6. This more closely matches str(), and
563 reduces surprises when adding alignment flags to the empty
564 presentation type. This also affects the new complex.__format__ in
565 the same way.
566
Martin v. Löwis011e8422009-05-05 04:43:17 +0000567- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000578- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
579 received a new method, detach(). detach() disconnects the underlying stream
580 from the buffer or text IO and returns it.
581
Mark Dickinson33841c32009-05-01 15:37:04 +0000582- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
583 floats with absolute value over 1e50. Also remove length
584 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
585 12.34 no longer raise an exception.

591 never gives more than the requested number of significant digits.
592
Eric Smith6dc46f52009-04-27 20:39:49 +0000593- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
594 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.

609 rounded for a float x, by using the decimal <-> binary conversions
610 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
611 consistently agrees with format(x, '.2f').
612
Benjamin Petersonae937c02009-04-18 20:54:08 +0000613- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +0000616- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
617
Eric Smith35e84722009-04-16 20:21:28 +0000618- Issue #5515: str.format() type 'n' combined with commas and leading
619 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000620
621- Implement PEP 378, Format Specifier for Thousands Separator, for
622 floats.
623
Mark Dickinson3370cce2009-04-17 22:40:53 +0000624- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000625 1e11, not 1e12. This avoids printing 13 significant digits in
626 situations where only 12 of them are correct. Example problem
627 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
628 long time.)
629
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000630- Issue #1580: On most platforms, use a 'short' float repr: for a
631 finite float x, repr(x) now outputs a string based on the shortest
632 sequence of decimal digits that rounds to x. Previous behaviour was
633 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000634 Another minor difference is that the new repr switches to
635 exponential notation at 1e16 instead of the previous 1e17; this
636 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000637
638 There's a new sys attribute sys.float_repr_style, which takes
639 the value 'short' to indicate that we're using short float repr,
640 and 'legacy' if the short float repr isn't available for one
641 reason or another.
642
643 The float repr change involves incorporating David Gay's 'perfect
644 rounding' code into the Python core (it's in Python/dtoa.c). As a
645 secondary consequence, all string-to-float and float-to-string
646 conversions (including all float formatting operations) will be
647 correctly rounded on these platforms.
648
649 See issue 1580 discussions for details of platforms for which
650 this change does not apply.
651
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000652- Issue #5759: float() didn't call __float__ on str subclasses.
653
Georg Brandlabc38772009-04-12 15:51:51 +0000654- The string.maketrans() function is deprecated; there is a new static method
655 maketrans() on the bytes and bytearray classes. This removes confusion about
656 the types string.maketrans() is supposed to work with, and mirrors the
657 methods available on the str class.
658
R. David Murraydc6da8a2009-04-09 22:16:43 +0000659- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

663 to avoid compiler warnings.
664
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000665- Issue #3739: The unicode-internal encoder now reports the number of characters

822
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000823- Issue #4688: Add a heuristic so that tuples and dicts containing only
824 untrackable objects are not tracked by the garbage collector. This can
825 reduce the size of collections and therefore the garbage collection overhead
826 on long-running programs, depending on their particular use of datatypes.

898 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
899 partial bzip2 compressed data.

944 source has already been decoded into str.
945
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000946- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
947 rotating the object pointer by 4 bits to the right.
948
Mark Dickinson87ec0852009-02-09 17:15:59 +0000949- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
950 it now forces its argument to double before testing for infinity.
951
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000952- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000961
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000962- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000963 were suppressing all exceptions. These include list() and bytearray().
964
Mark Dickinson1124e712009-01-28 21:25:58 +0000965- Issue #4707: round(x, n) now returns an integer if x is an integer.
966 Previously it returned a float.
967
Antoine Pitroub52ec782009-01-25 16:34:23 +0000968- Issue #4753: By enabling a configure option named '--with-computed-gotos'
969 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
970 evaluation loop is compiled with a new dispatch mechanism which gives
971 speedups of up to 20%, depending on the system, on various benchmarks.
972
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000973- Issue #4874: Most builtin decoders now reject unicode input.

979
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000980- Issue #4838: When a module is deallocated, free the memory backing the
981 optional module state data.
982
Mark Dickinson8055afd2009-01-17 10:04:45 +0000983- Issue #4910: Rename nb_long slot to nb_reserved, and change its
984 type to (void *).
985
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000986- Issue #4935: The overflow checking code in the expandtabs() method common
987 to str, bytes and bytearray could be optimized away by the compiler, letting
988 the interpreter segfault instead of raising an error.
989
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000990- Issue #3720: Fix a crash when an iterator modifies its class and removes its
991 __next__ method.
992
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000993- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
994 function no longer attempt to call the __long__ slot to convert an object
995 to an integer. Only the __int__ and __trunc__ slots are examined.
996
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +0000997- Issue #4893: Use NT threading on CE.
998

1000
Antoine Pitrouab868312009-01-10 15:40:25 +00001001- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1002 common cases are optimized thanks to a dedicated fast path and a moderate
1003 amount of loop unrolling.
1004
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001005- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1006 collecting the oldest generation) so that allocating lots of objects without
1007 destroying them does not show quadratic performance. Based on a proposal by
1008 Martin von Löwis at
1009 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1010
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001011- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001012 having been closed (for instance, a read() call could return some
1013 previously buffered data). Patch by Dmitry Vasiliev.
1014
Antoine Pitrou05608432009-01-09 18:53:14 +00001015- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1016 flag to work properly. Furthermore, when specifying -u, the text stdout
1017 and stderr streams have line-by-line buffering enabled (the default being
1018 to buffer arbitrary chunks of data).
1019
Raymond Hettinger35631532009-01-09 03:58:09 +00001020- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1021 instead of ints (reducing its size from 4 to 8 times thereby reducing
1022 Python's overall memory).
1023
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001024- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1025 an existing .py counterpart, override the co_filename attributes of all
1026 code objects if the original filename is obsolete (which can happen if the
1027 file has been renamed, moved, or if it is accessed through different paths).
1028 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1029
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001030- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1031 one byte. Also fixes the meaning of len() so that it returns the number of
1032 items, rather than the size in bytes.
1033
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001034- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1035
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001036- Issue #4747: When the terminal does not use utf-8, executing a script with
1037 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1038
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001039- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001040 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001041
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001042- Issue #3680: Reference cycles created through a dict, set or deque iterator
1043 did not get collected.
1044
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001045- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1046 where the tp_hash and tp_dict slots are both NULL.
1047
Georg Brandlccc47b62008-12-28 11:44:14 +00001048- Issue #4759: None is now allowed as the first argument of
1049 bytearray.translate(). It was always allowed for bytes.translate().
1050
Skip Montanaro80072cb2008-12-23 03:51:14 +00001051- Added test case to ensure attempts to read from a file opened for writing
1052 fail.
1053
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001054- Issue #3106: Speedup some comparisons (str/str and int/int).

1058
Antoine Pitrou621601a2008-12-17 23:18:19 +00001059- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1060 print elapsed times, not only when some objects are uncollectable /
1061 unreachable. Original patch by Neil Schemenauer.
1062
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001063- Issue #3439: Add a bit_length method to int.
1064
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001065- Issue #2173: When getting device encoding, check that return value of
1066 nl_langinfo is not the empty string. This was causing silent build
1067 failures on OS X.
1068
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001069- Issue #4597: Fixed several opcodes that weren't always propagating
1070 exceptions.
1071
1072- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001073 context manager returns a value that cannot be converted to a bool.
1074
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001075- Issue #4445: Replace "sizeof(PyBytesObject)" with
1076 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1077 bytes instances. On a typical machine this saves 3 bytes of memory
1078 (on average) per allocation of a bytes instance.
1079
Christian Heimesa872de52008-12-05 08:26:55 +00001080- Issue #4533: File read operation was dreadfully slow due to a slowly
1081 growing read buffer. Fixed by using the same growth rate algorithm as
1082 Python 2.x.
1083
Antoine Pitrou5504e892008-12-06 21:27:53 +00001084- Issue #4509: Various issues surrounding resize of bytearray objects to
1085 which there are buffer exports (e.g. memoryview instances).
1086
Georg Brandlf9734072008-12-07 15:30:06 +00001087- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1088 method on file objects with closefd=False. The file descriptor is still
1089 kept open but the file object behaves like a closed file. The ``FileIO``
1090 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001091
Antoine Pitroubc420402008-12-07 20:14:49 +00001092- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1098
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001099- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1100 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1101 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1102 of using the replace error handler in PyUnicode_DecodeUTF8().

1119 opening an empty or very small file.
1120
1121- Issue #6545: Removed assert statements in distutils.Extension, so the
