320 default precision of 12. Previously, the behavior the same but with
321 a default precision of 6. This more closely matches str(), and
322 reduces surprises when adding alignment flags to the empty
323 presentation type. This also affects the new complex.__format__ in
324 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000337- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
338 received a new method, detach(). detach() disconnects the underlying stream
339 from the buffer or text IO and returns it.
340
Mark Dickinson33841c32009-05-01 15:37:04 +0000341- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
342 floats with absolute value over 1e50. Also remove length
343 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
344 12.34 no longer raise an exception.

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000367- Issue #1869 (and many duplicates): make round(x, n) correctly
368 rounded for a float x, by using the decimal <-> binary conversions
369 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
370 consistently agrees with format(x, '.2f').
371
Benjamin Petersonae937c02009-04-18 20:54:08 +0000372- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

376
Eric Smith35e84722009-04-16 20:21:28 +0000377- Issue #5515: str.format() type 'n' combined with commas and leading
378 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000379
380- Implement PEP 378, Format Specifier for Thousands Separator, for
381 floats.
382
Mark Dickinson3370cce2009-04-17 22:40:53 +0000383- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000384 1e11, not 1e12. This avoids printing 13 significant digits in
385 situations where only 12 of them are correct. Example problem
386 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
387 long time.)
388
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000389- Issue #1580: On most platforms, use a 'short' float repr: for a
390 finite float x, repr(x) now outputs a string based on the shortest
391 sequence of decimal digits that rounds to x. Previous behaviour was
392 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000393 Another minor difference is that the new repr switches to
394 exponential notation at 1e16 instead of the previous 1e17; this
395 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000396
397 There's a new sys attribute sys.float_repr_style, which takes
398 the value 'short' to indicate that we're using short float repr,
399 and 'legacy' if the short float repr isn't available for one
400 reason or another.
401
402 The float repr change involves incorporating David Gay's 'perfect
403 rounding' code into the Python core (it's in Python/dtoa.c). As a
404 secondary consequence, all string-to-float and float-to-string
405 conversions (including all float formatting operations) will be
406 correctly rounded on these platforms.
407
408 See issue 1580 discussions for details of platforms for which
409 this change does not apply.
410
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000411- Issue #5759: float() didn't call __float__ on str subclasses.
412
Georg Brandlabc38772009-04-12 15:51:51 +0000413- The string.maketrans() function is deprecated; there is a new static method
414 maketrans() on the bytes and bytearray classes. This removes confusion about
415 the types string.maketrans() is supposed to work with, and mirrors the
416 methods available on the str class.
417
R. David Murraydc6da8a2009-04-09 22:16:43 +0000418- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

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

Mark Dickinsonb40b9472009-03-29 16:58:21 +0000679 struct.error instead of returning b'\xff\xff\xff\xff'. The
680 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000721- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000722 were suppressing all exceptions. These include list() and bytearray().
723
Mark Dickinson1124e712009-01-28 21:25:58 +0000724- Issue #4707: round(x, n) now returns an integer if x is an integer.
725 Previously it returned a float.
726
Antoine Pitroub52ec782009-01-25 16:34:23 +0000727- Issue #4753: By enabling a configure option named '--with-computed-gotos'
728 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
729 evaluation loop is compiled with a new dispatch mechanism which gives
730 speedups of up to 20%, depending on the system, on various benchmarks.
731
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000732- Issue #4874: Most builtin decoders now reject unicode input.

740 optional module state data.
741
Mark Dickinson8055afd2009-01-17 10:04:45 +0000742- Issue #4910: Rename nb_long slot to nb_reserved, and change its
743 type to (void *).
744
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000745- Issue #4935: The overflow checking code in the expandtabs() method common
746 to str, bytes and bytearray could be optimized away by the compiler, letting
747 the interpreter segfault instead of raising an error.
748
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000749- Issue #3720: Fix a crash when an iterator modifies its class and removes its
750 __next__ method.
751
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000752- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
753 function no longer attempt to call the __long__ slot to convert an object
754 to an integer. Only the __int__ and __trunc__ slots are examined.
755

759
Antoine Pitrouab868312009-01-10 15:40:25 +0000760- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
761 common cases are optimized thanks to a dedicated fast path and a moderate
762 amount of loop unrolling.
763
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000764- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
765 collecting the oldest generation) so that allocating lots of objects without
766 destroying them does not show quadratic performance. Based on a proposal by
767 Martin von Löwis at
768 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
769
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000770- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000771 having been closed (for instance, a read() call could return some
772 previously buffered data). Patch by Dmitry Vasiliev.
773
Antoine Pitrou05608432009-01-09 18:53:14 +0000774- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
775 flag to work properly. Furthermore, when specifying -u, the text stdout
776 and stderr streams have line-by-line buffering enabled (the default being
777 to buffer arbitrary chunks of data).
778
Raymond Hettinger35631532009-01-09 03:58:09 +0000779- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
780 instead of ints (reducing its size from 4 to 8 times thereby reducing
781 Python's overall memory).
782
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000783- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
784 an existing .py counterpart, override the co_filename attributes of all
785 code objects if the original filename is obsolete (which can happen if the
786 file has been renamed, moved, or if it is accessed through different paths).
787 Patch by Ziga Seilnacht and Jean-Paul Calderone.
788
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000789- Issue #4580: Fix slicing of memoryviews when the item size is greater than
790 one byte. Also fixes the meaning of len() so that it returns the number of
791 items, rather than the size in bytes.
792
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000793- Issue #4075: Use OutputDebugStringW in Py_FatalError.
794
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000795- Issue #4747: When the terminal does not use utf-8, executing a script with
796 non-ascii characters in its name could fail with a "SyntaxError: None" error.
797
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000798- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000799 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000800

802 did not get collected.
803
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000804- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
805 where the tp_hash and tp_dict slots are both NULL.
806
Georg Brandlccc47b62008-12-28 11:44:14 +0000807- Issue #4759: None is now allowed as the first argument of
808 bytearray.translate(). It was always allowed for bytes.translate().
809
Skip Montanaro80072cb2008-12-23 03:51:14 +0000810- Added test case to ensure attempts to read from a file opened for writing
811 fail.
812
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000813- Issue #3106: Speedup some comparisons (str/str and int/int).

817
Antoine Pitrou621601a2008-12-17 23:18:19 +0000818- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
819 print elapsed times, not only when some objects are uncollectable /
820 unreachable. Original patch by Neil Schemenauer.
821
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000822- Issue #3439: Add a bit_length method to int.
823
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000824- Issue #2173: When getting device encoding, check that return value of
825 nl_langinfo is not the empty string. This was causing silent build
826 failures on OS X.
827
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000828- Issue #4597: Fixed several opcodes that weren't always propagating
829 exceptions.
830
831- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000832 context manager returns a value that cannot be converted to a bool.
833
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000834- Issue #4445: Replace "sizeof(PyBytesObject)" with
835 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
836 bytes instances. On a typical machine this saves 3 bytes of memory
837 (on average) per allocation of a bytes instance.
838
Christian Heimesa872de52008-12-05 08:26:55 +0000839- Issue #4533: File read operation was dreadfully slow due to a slowly
840 growing read buffer. Fixed by using the same growth rate algorithm as
841 Python 2.x.
842
Antoine Pitrou5504e892008-12-06 21:27:53 +0000843- Issue #4509: Various issues surrounding resize of bytearray objects to
844 which there are buffer exports (e.g. memoryview instances).
845
Georg Brandlf9734072008-12-07 15:30:06 +0000846- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
847 method on file objects with closefd=False. The file descriptor is still
848 kept open but the file object behaves like a closed file. The ``FileIO``
849 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000850
Antoine Pitroubc420402008-12-07 20:14:49 +0000851- Issue #4569: Interpreter crash when mutating a memoryview with an item size
852 larger than 1.

857
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000858- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
859 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
860 step. This avoids problems with counting UTF-8 bytes that ignores the effect
861 of using the replace error handler in PyUnicode_DecodeUTF8().
