Mark Dickinson865e01a2009-05-07 16:37:01 +0000282- Issue #5914: Add new C API function PyOS_string_to_double, and
283 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
284
Eric Smith741191f2009-05-06 13:08:15 +0000285- Issue #3382: float.__format__, complex.__format__, and %-formatting
286 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

Mark Hammond5a607a32009-05-06 08:04:54 +0000289- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
290 in all operations, including splitdrive, split, etc. splitunc() now issues
291 a PendingDeprecation warning.

Eric Smith63376222009-05-05 14:04:18 +0000293- Issue #5920: For float.__format__, change the behavior with the
294 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
295 to be like 'g' but with at least one decimal point and with a
296 default precision of 12. Previously, the behavior the same but with
297 a default precision of 6. This more closely matches str(), and
298 reduces surprises when adding alignment flags to the empty
299 presentation type. This also affects the new complex.__format__ in
300 the same way.

314 received a new method, detach(). detach() disconnects the underlying stream
315 from the buffer or text IO and returns it.
316
Mark Dickinson33841c32009-05-01 15:37:04 +0000317- Issue #5859: Remove switch from '%f' to '%g'-style formatting for

Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000341- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000342
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000343- Issue #1869 (and many duplicates): make round(x, n) correctly
344 rounded for a float x, by using the decimal <-> binary conversions
345 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
346 consistently agrees with format(x, '.2f').
347
Benjamin Petersonae937c02009-04-18 20:54:08 +0000348- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +0000351- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
352
Eric Smith35e84722009-04-16 20:21:28 +0000353- Issue #5515: str.format() type 'n' combined with commas and leading
354 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000355
356- Implement PEP 378, Format Specifier for Thousands Separator, for
357 floats.
358
Mark Dickinson3370cce2009-04-17 22:40:53 +0000359- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000360 1e11, not 1e12. This avoids printing 13 significant digits in
361 situations where only 12 of them are correct. Example problem
362 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
363 long time.)
364
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000365- Issue #1580: On most platforms, use a 'short' float repr: for a
366 finite float x, repr(x) now outputs a string based on the shortest
367 sequence of decimal digits that rounds to x. Previous behaviour was
368 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000369 Another minor difference is that the new repr switches to
370 exponential notation at 1e16 instead of the previous 1e17; this
371 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000372
373 There's a new sys attribute sys.float_repr_style, which takes
374 the value 'short' to indicate that we're using short float repr,
375 and 'legacy' if the short float repr isn't available for one
376 reason or another.
377
378 The float repr change involves incorporating David Gay's 'perfect
379 rounding' code into the Python core (it's in Python/dtoa.c). As a
380 secondary consequence, all string-to-float and float-to-string
381 conversions (including all float formatting operations) will be
382 correctly rounded on these platforms.
383
384 See issue 1580 discussions for details of platforms for which
385 this change does not apply.
386
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000387- Issue #5759: float() didn't call __float__ on str subclasses.
388
Georg Brandlabc38772009-04-12 15:51:51 +0000389- The string.maketrans() function is deprecated; there is a new static method
390 maketrans() on the bytes and bytearray classes. This removes confusion about
391 the types string.maketrans() is supposed to work with, and mirrors the
392 methods available on the str class.
393
R. David Murraydc6da8a2009-04-09 22:16:43 +0000394- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

557
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000558- Issue #4688: Add a heuristic so that tuples and dicts containing only
559 untrackable objects are not tracked by the garbage collector. This can
560 reduce the size of collections and therefore the garbage collection overhead
561 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonae681df2009-03-21 10:26:31 +0000653- Issue #5463: In struct module, remove deprecated overflow wrapping
654 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +0000655 struct.error instead of returning b'\xff\xff\xff\xff'. The
656 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
657 have been removed from the struct module.

676 contained non ascii character on windows.
677
Benjamin Petersonf5b52242009-03-02 23:31:26 +0000678- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
679 source has already been decoded into str.
680
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000681- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
682 rotating the object pointer by 4 bits to the right.
683
Mark Dickinson87ec0852009-02-09 17:15:59 +0000684- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
685 it now forces its argument to double before testing for infinity.
686
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000687- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
688 returns a non-number type.

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000697- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000698 were suppressing all exceptions. These include list() and bytearray().
699
Mark Dickinson1124e712009-01-28 21:25:58 +0000700- Issue #4707: round(x, n) now returns an integer if x is an integer.
701 Previously it returned a float.
702
Antoine Pitroub52ec782009-01-25 16:34:23 +0000703- Issue #4753: By enabling a configure option named '--with-computed-gotos'
704 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
705 evaluation loop is compiled with a new dispatch mechanism which gives
706 speedups of up to 20%, depending on the system, on various benchmarks.
707
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000708- Issue #4874: Most builtin decoders now reject unicode input.

711 from a string.
712
Benjamin Peterson05e782f2009-01-19 15:15:02 +0000713- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
714
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000715- Issue #4838: When a module is deallocated, free the memory backing the
716 optional module state data.
717
Mark Dickinson8055afd2009-01-17 10:04:45 +0000718- Issue #4910: Rename nb_long slot to nb_reserved, and change its
719 type to (void *).
720
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000721- Issue #4935: The overflow checking code in the expandtabs() method common
722 to str, bytes and bytearray could be optimized away by the compiler, letting
723 the interpreter segfault instead of raising an error.
724
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000725- Issue #3720: Fix a crash when an iterator modifies its class and removes its
726 __next__ method.
727
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000728- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
729 function no longer attempt to call the __long__ slot to convert an object
730 to an integer. Only the __int__ and __trunc__ slots are examined.
731
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +0000732- Issue #4893: Use NT threading on CE.
733

735
Antoine Pitrouab868312009-01-10 15:40:25 +0000736- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
737 common cases are optimized thanks to a dedicated fast path and a moderate
738 amount of loop unrolling.
739
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000740- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
741 collecting the oldest generation) so that allocating lots of objects without
742 destroying them does not show quadratic performance. Based on a proposal by
743 Martin von Löwis at
744 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
745
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000746- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000747 having been closed (for instance, a read() call could return some
748 previously buffered data). Patch by Dmitry Vasiliev.
749
Antoine Pitrou05608432009-01-09 18:53:14 +0000750- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
751 flag to work properly. Furthermore, when specifying -u, the text stdout
752 and stderr streams have line-by-line buffering enabled (the default being
753 to buffer arbitrary chunks of data).
754
Raymond Hettinger35631532009-01-09 03:58:09 +0000755- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
756 instead of ints (reducing its size from 4 to 8 times thereby reducing
757 Python's overall memory).
758
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000759- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
760 an existing .py counterpart, override the co_filename attributes of all
761 code objects if the original filename is obsolete (which can happen if the
762 file has been renamed, moved, or if it is accessed through different paths).
763 Patch by Ziga Seilnacht and Jean-Paul Calderone.
764
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000765- Issue #4580: Fix slicing of memoryviews when the item size is greater than
766 one byte. Also fixes the meaning of len() so that it returns the number of
767 items, rather than the size in bytes.
768
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000769- Issue #4075: Use OutputDebugStringW in Py_FatalError.
770
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000771- Issue #4747: When the terminal does not use utf-8, executing a script with
772 non-ascii characters in its name could fail with a "SyntaxError: None" error.
773
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000774- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000775 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000776
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000777- Issue #3680: Reference cycles created through a dict, set or deque iterator
778 did not get collected.
779
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000780- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
781 where the tp_hash and tp_dict slots are both NULL.
782
Georg Brandlccc47b62008-12-28 11:44:14 +0000783- Issue #4759: None is now allowed as the first argument of
784 bytearray.translate(). It was always allowed for bytes.translate().
785
Skip Montanaro80072cb2008-12-23 03:51:14 +0000786- Added test case to ensure attempts to read from a file opened for writing
787 fail.
788
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000789- Issue #3106: Speedup some comparisons (str/str and int/int).
790
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000791- Issue #2183: Simplify and optimize bytecode for list, dict and set
792 comprehensions. Original patch for list comprehensions by Neal Norwitz.
793
Antoine Pitrou621601a2008-12-17 23:18:19 +0000794- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
795 print elapsed times, not only when some objects are uncollectable /
796 unreachable. Original patch by Neil Schemenauer.
797
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000798- Issue #3439: Add a bit_length method to int.
799
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000800- Issue #2173: When getting device encoding, check that return value of
801 nl_langinfo is not the empty string. This was causing silent build
802 failures on OS X.
803
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000804- Issue #4597: Fixed several opcodes that weren't always propagating
805 exceptions.
806
807- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000808 context manager returns a value that cannot be converted to a bool.
809
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000810- Issue #4445: Replace "sizeof(PyBytesObject)" with
811 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
812 bytes instances. On a typical machine this saves 3 bytes of memory
813 (on average) per allocation of a bytes instance.
814
Christian Heimesa872de52008-12-05 08:26:55 +0000815- Issue #4533: File read operation was dreadfully slow due to a slowly
816 growing read buffer. Fixed by using the same growth rate algorithm as
817 Python 2.x.
818
Antoine Pitrou5504e892008-12-06 21:27:53 +0000819- Issue #4509: Various issues surrounding resize of bytearray objects to
820 which there are buffer exports (e.g. memoryview instances).
821
Georg Brandlf9734072008-12-07 15:30:06 +0000822- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
823 method on file objects with closefd=False. The file descriptor is still
824 kept open but the file object behaves like a closed file. The ``FileIO``
825 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000826
Antoine Pitroubc420402008-12-07 20:14:49 +0000827- Issue #4569: Interpreter crash when mutating a memoryview with an item size
828 larger than 1.
829
Benjamin Peterson371ccfb2008-12-27 19:03:36 +0000830- Issue #4748: Lambda generators no longer return a value.
831
Gregory P. Smithccc5ae72009-03-02 05:21:55 +0000832- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
833
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000834- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
835 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
836 step. This avoids problems with counting UTF-8 bytes that ignores the effect
837 of using the replace error handler in PyUnicode_DecodeUTF8().
