435 (1) inf and nan strings with trailing whitespace were incorrectly
436 rejected; (2) parsing of strings representing infinities and nans
437 was locale aware; and (3) the interpretation of fromhex('-nan')
438 didn't match that of float('-nan').

489 library. This means, for example, that opening an UTF-16 text file in
490 append mode doesn't add a BOM at the end of the file if the file isn't
491 empty.
492
R. David Murray74b89242009-05-13 17:33:03 +0000493- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

541Core and Builtins

543
Mark Dickinson865e01a2009-05-07 16:37:01 +0000544- Issue #5914: Add new C API function PyOS_string_to_double, and
545 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
546
Eric Smith741191f2009-05-06 13:08:15 +0000547- Issue #3382: float.__format__, complex.__format__, and %-formatting
548 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
549 affects nan -> NAN and inf -> INF.
550
Mark Hammond5a607a32009-05-06 08:04:54 +0000551- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
552 in all operations, including splitdrive, split, etc. splitunc() now issues
553 a PendingDeprecation warning.
554
Eric Smith63376222009-05-05 14:04:18 +0000555- Issue #5920: For float.__format__, change the behavior with the
556 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
557 to be like 'g' but with at least one decimal point and with a
558 default precision of 12. Previously, the behavior the same but with
559 a default precision of 6. This more closely matches str(), and
560 reduces surprises when adding alignment flags to the empty
561 presentation type. This also affects the new complex.__format__ in
562 the same way.
563
Martin v. Löwis011e8422009-05-05 04:43:17 +0000564- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Martin v. Löwisdb12d452009-05-02 18:52:14 +0000574
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000575- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
576 received a new method, detach(). detach() disconnects the underlying stream
577 from the buffer or text IO and returns it.
578
Mark Dickinson33841c32009-05-01 15:37:04 +0000579- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
580 floats with absolute value over 1e50. Also remove length
581 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
582 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000583

588 never gives more than the requested number of significant digits.
589
Eric Smith6dc46f52009-04-27 20:39:49 +0000590- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
591 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
592

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000605- Issue #1869 (and many duplicates): make round(x, n) correctly
606 rounded for a float x, by using the decimal <-> binary conversions
607 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
608 consistently agrees with format(x, '.2f').
609
Benjamin Petersonae937c02009-04-18 20:54:08 +0000610- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

614
Eric Smith35e84722009-04-16 20:21:28 +0000615- Issue #5515: str.format() type 'n' combined with commas and leading
616 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000617
618- Implement PEP 378, Format Specifier for Thousands Separator, for
619 floats.
620
Mark Dickinson3370cce2009-04-17 22:40:53 +0000621- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000622 1e11, not 1e12. This avoids printing 13 significant digits in
623 situations where only 12 of them are correct. Example problem
624 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
625 long time.)
626
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000627- Issue #1580: On most platforms, use a 'short' float repr: for a
628 finite float x, repr(x) now outputs a string based on the shortest
629 sequence of decimal digits that rounds to x. Previous behaviour was
630 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000631 Another minor difference is that the new repr switches to
632 exponential notation at 1e16 instead of the previous 1e17; this
633 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000634
635 There's a new sys attribute sys.float_repr_style, which takes
636 the value 'short' to indicate that we're using short float repr,
637 and 'legacy' if the short float repr isn't available for one
638 reason or another.
639
640 The float repr change involves incorporating David Gay's 'perfect
641 rounding' code into the Python core (it's in Python/dtoa.c). As a
642 secondary consequence, all string-to-float and float-to-string
643 conversions (including all float formatting operations) will be
644 correctly rounded on these platforms.
645
646 See issue 1580 discussions for details of platforms for which
647 this change does not apply.
648
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000649- Issue #5759: float() didn't call __float__ on str subclasses.
650
Georg Brandlabc38772009-04-12 15:51:51 +0000651- The string.maketrans() function is deprecated; there is a new static method
652 maketrans() on the bytes and bytearray classes. This removes confusion about
653 the types string.maketrans() is supposed to work with, and mirrors the
654 methods available on the str class.
655
R. David Murraydc6da8a2009-04-09 22:16:43 +0000656- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

821 untrackable objects are not tracked by the garbage collector. This can
822 reduce the size of collections and therefore the garbage collection overhead
823 on long-running programs, depending on their particular use of datatypes.

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

936
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +0000937- Issue #5249: time.strftime returned malformed string when format string
938 contained non ascii character on windows.
939

941 source has already been decoded into str.
942
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000943- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
944 rotating the object pointer by 4 bits to the right.
945
Mark Dickinson87ec0852009-02-09 17:15:59 +0000946- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
947 it now forces its argument to double before testing for infinity.
948
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000949- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

957 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000958
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000959- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000960 were suppressing all exceptions. These include list() and bytearray().
961
Mark Dickinson1124e712009-01-28 21:25:58 +0000962- Issue #4707: round(x, n) now returns an integer if x is an integer.
963 Previously it returned a float.
964
Antoine Pitroub52ec782009-01-25 16:34:23 +0000965- Issue #4753: By enabling a configure option named '--with-computed-gotos'
966 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
967 evaluation loop is compiled with a new dispatch mechanism which gives
968 speedups of up to 20%, depending on the system, on various benchmarks.
969
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000970- Issue #4874: Most builtin decoders now reject unicode input.

976
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000977- Issue #4838: When a module is deallocated, free the memory backing the
978 optional module state data.
979
Mark Dickinson8055afd2009-01-17 10:04:45 +0000980- Issue #4910: Rename nb_long slot to nb_reserved, and change its
981 type to (void *).
982
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000983- Issue #4935: The overflow checking code in the expandtabs() method common
984 to str, bytes and bytearray could be optimized away by the compiler, letting
985 the interpreter segfault instead of raising an error.
986
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000987- Issue #3720: Fix a crash when an iterator modifies its class and removes its
988 __next__ method.
989
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000990- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
991 function no longer attempt to call the __long__ slot to convert an object
992 to an integer. Only the __int__ and __trunc__ slots are examined.
993
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +0000994- Issue #4893: Use NT threading on CE.
995

997
Antoine Pitrouab868312009-01-10 15:40:25 +0000998- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
999 common cases are optimized thanks to a dedicated fast path and a moderate
1000 amount of loop unrolling.
1001
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001002- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1003 collecting the oldest generation) so that allocating lots of objects without
1004 destroying them does not show quadratic performance. Based on a proposal by
1005 Martin von Löwis at
1006 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1007
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001008- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001009 having been closed (for instance, a read() call could return some
1010 previously buffered data). Patch by Dmitry Vasiliev.
1011
Antoine Pitrou05608432009-01-09 18:53:14 +00001012- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1013 flag to work properly. Furthermore, when specifying -u, the text stdout
1014 and stderr streams have line-by-line buffering enabled (the default being
1015 to buffer arbitrary chunks of data).
1016
Raymond Hettinger35631532009-01-09 03:58:09 +00001017- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1018 instead of ints (reducing its size from 4 to 8 times thereby reducing
1019 Python's overall memory).
1020
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001021- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1022 an existing .py counterpart, override the co_filename attributes of all
1023 code objects if the original filename is obsolete (which can happen if the
1024 file has been renamed, moved, or if it is accessed through different paths).
1025 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1026
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001027- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1028 one byte. Also fixes the meaning of len() so that it returns the number of
1029 items, rather than the size in bytes.
1030
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001031- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1032
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001033- Issue #4747: When the terminal does not use utf-8, executing a script with
1034 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1035
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001036- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001037 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001038
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001039- Issue #3680: Reference cycles created through a dict, set or deque iterator
1040 did not get collected.
1041
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001042- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1043 where the tp_hash and tp_dict slots are both NULL.
1044
Georg Brandlccc47b62008-12-28 11:44:14 +00001045- Issue #4759: None is now allowed as the first argument of
1046 bytearray.translate(). It was always allowed for bytes.translate().
1047
Skip Montanaro80072cb2008-12-23 03:51:14 +00001048- Added test case to ensure attempts to read from a file opened for writing
1049 fail.
1050

1054 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1055
Antoine Pitrou621601a2008-12-17 23:18:19 +00001056- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1057 print elapsed times, not only when some objects are uncollectable /
1058 unreachable. Original patch by Neil Schemenauer.
1059
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001060- Issue #3439: Add a bit_length method to int.
1061
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001062- Issue #2173: When getting device encoding, check that return value of
1063 nl_langinfo is not the empty string. This was causing silent build
1064 failures on OS X.
1065
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001066- Issue #4597: Fixed several opcodes that weren't always propagating
1067 exceptions.
1068
1069- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001070 context manager returns a value that cannot be converted to a bool.
1071
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001072- Issue #4445: Replace "sizeof(PyBytesObject)" with
1073 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1074 bytes instances. On a typical machine this saves 3 bytes of memory
1075 (on average) per allocation of a bytes instance.
1076
Christian Heimesa872de52008-12-05 08:26:55 +00001077- Issue #4533: File read operation was dreadfully slow due to a slowly
1078 growing read buffer. Fixed by using the same growth rate algorithm as
1079 Python 2.x.
1080
Antoine Pitrou5504e892008-12-06 21:27:53 +00001081- Issue #4509: Various issues surrounding resize of bytearray objects to
1082 which there are buffer exports (e.g. memoryview instances).
1083
Georg Brandlf9734072008-12-07 15:30:06 +00001084- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1085 method on file objects with closefd=False. The file descriptor is still
1086 kept open but the file object behaves like a closed file. The ``FileIO``
1087 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001088
Antoine Pitroubc420402008-12-07 20:14:49 +00001089- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1090 larger than 1.

1095
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001096- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1097 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1098 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1099 of using the replace error handler in PyUnicode_DecodeUTF8().

1116 opening an empty or very small file.
1117
1118- Issue #6545: Removed assert statements in distutils.Extension, so the
