311 default precision of 12. Previously, the behavior the same but with
312 a default precision of 6. This more closely matches str(), and

314 presentation type. This also affects the new complex.__format__ in
315 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000328- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
329 received a new method, detach(). detach() disconnects the underlying stream
330 from the buffer or text IO and returns it.
331
Mark Dickinson33841c32009-05-01 15:37:04 +0000332- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
333 floats with absolute value over 1e50. Also remove length
334 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
335 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +0000337- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000338 format(complex(1, 2./3), '.5') now produces a sensible result.
339
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000340- Issue #5864: Fix empty format code formatting for floats so that it

Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000356- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000357
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000358- Issue #1869 (and many duplicates): make round(x, n) correctly
359 rounded for a float x, by using the decimal <-> binary conversions
360 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
361 consistently agrees with format(x, '.2f').
362
Benjamin Petersonae937c02009-04-18 20:54:08 +0000363- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

367
Eric Smith35e84722009-04-16 20:21:28 +0000368- Issue #5515: str.format() type 'n' combined with commas and leading
369 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000370
371- Implement PEP 378, Format Specifier for Thousands Separator, for
372 floats.
373
Mark Dickinson3370cce2009-04-17 22:40:53 +0000374- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000375 1e11, not 1e12. This avoids printing 13 significant digits in
376 situations where only 12 of them are correct. Example problem
377 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
378 long time.)
379
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000380- Issue #1580: On most platforms, use a 'short' float repr: for a
381 finite float x, repr(x) now outputs a string based on the shortest
382 sequence of decimal digits that rounds to x. Previous behaviour was
383 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000384 Another minor difference is that the new repr switches to
385 exponential notation at 1e16 instead of the previous 1e17; this
386 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000387
388 There's a new sys attribute sys.float_repr_style, which takes
389 the value 'short' to indicate that we're using short float repr,
390 and 'legacy' if the short float repr isn't available for one
391 reason or another.
392
393 The float repr change involves incorporating David Gay's 'perfect
394 rounding' code into the Python core (it's in Python/dtoa.c). As a
395 secondary consequence, all string-to-float and float-to-string
396 conversions (including all float formatting operations) will be
397 correctly rounded on these platforms.
398
399 See issue 1580 discussions for details of platforms for which
400 this change does not apply.
401
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000402- Issue #5759: float() didn't call __float__ on str subclasses.
403
Georg Brandlabc38772009-04-12 15:51:51 +0000404- The string.maketrans() function is deprecated; there is a new static method
405 maketrans() on the bytes and bytearray classes. This removes confusion about
406 the types string.maketrans() is supposed to work with, and mirrors the
407 methods available on the str class.
408
R. David Murraydc6da8a2009-04-09 22:16:43 +0000409- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

575 reduce the size of collections and therefore the garbage collection overhead
576 on long-running programs, depending on their particular use of datatypes.

645
Lars Gustäbel42e00912009-03-22 20:34:29 +0000646- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
647 forever on incomplete input. That caused tarfile.open() to hang when used
648 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
649 partial bzip2 compressed data.
650
Mark Dickinson79f52032009-03-17 23:12:51 +0000651- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +0000670 struct.error instead of returning b'\xff\xff\xff\xff'. The
671 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
672 have been removed from the struct module.

691 contained non ascii character on windows.
692
Benjamin Petersonf5b52242009-03-02 23:31:26 +0000693- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
694 source has already been decoded into str.
695
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000696- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
697 rotating the object pointer by 4 bits to the right.
698
Mark Dickinson87ec0852009-02-09 17:15:59 +0000699- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
700 it now forces its argument to double before testing for infinity.
701
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000702- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000712- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000713 were suppressing all exceptions. These include list() and bytearray().
714
Mark Dickinson1124e712009-01-28 21:25:58 +0000715- Issue #4707: round(x, n) now returns an integer if x is an integer.
716 Previously it returned a float.
717
Antoine Pitroub52ec782009-01-25 16:34:23 +0000718- Issue #4753: By enabling a configure option named '--with-computed-gotos'
719 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
720 evaluation loop is compiled with a new dispatch mechanism which gives
721 speedups of up to 20%, depending on the system, on various benchmarks.
722
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000723- Issue #4874: Most builtin decoders now reject unicode input.

727
Benjamin Peterson05e782f2009-01-19 15:15:02 +0000728- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
729
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000730- Issue #4838: When a module is deallocated, free the memory backing the
731 optional module state data.
732
Mark Dickinson8055afd2009-01-17 10:04:45 +0000733- Issue #4910: Rename nb_long slot to nb_reserved, and change its
734 type to (void *).
735
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000736- Issue #4935: The overflow checking code in the expandtabs() method common
737 to str, bytes and bytearray could be optimized away by the compiler, letting
738 the interpreter segfault instead of raising an error.
739
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000740- Issue #3720: Fix a crash when an iterator modifies its class and removes its
741 __next__ method.
742
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000743- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
744 function no longer attempt to call the __long__ slot to convert an object
745 to an integer. Only the __int__ and __trunc__ slots are examined.
746
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +0000747- Issue #4893: Use NT threading on CE.

750
Antoine Pitrouab868312009-01-10 15:40:25 +0000751- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
752 common cases are optimized thanks to a dedicated fast path and a moderate
753 amount of loop unrolling.
754
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000755- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
756 collecting the oldest generation) so that allocating lots of objects without
757 destroying them does not show quadratic performance. Based on a proposal by
758 Martin von Löwis at
759 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
760
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000761- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000762 having been closed (for instance, a read() call could return some
763 previously buffered data). Patch by Dmitry Vasiliev.
764
Antoine Pitrou05608432009-01-09 18:53:14 +0000765- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
766 flag to work properly. Furthermore, when specifying -u, the text stdout
767 and stderr streams have line-by-line buffering enabled (the default being
768 to buffer arbitrary chunks of data).
769
Raymond Hettinger35631532009-01-09 03:58:09 +0000770- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
771 instead of ints (reducing its size from 4 to 8 times thereby reducing
772 Python's overall memory).
773
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000774- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
775 an existing .py counterpart, override the co_filename attributes of all
776 code objects if the original filename is obsolete (which can happen if the
777 file has been renamed, moved, or if it is accessed through different paths).
778 Patch by Ziga Seilnacht and Jean-Paul Calderone.
779
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000780- Issue #4580: Fix slicing of memoryviews when the item size is greater than
781 one byte. Also fixes the meaning of len() so that it returns the number of
782 items, rather than the size in bytes.
783
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000784- Issue #4075: Use OutputDebugStringW in Py_FatalError.
785
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000786- Issue #4747: When the terminal does not use utf-8, executing a script with
787 non-ascii characters in its name could fail with a "SyntaxError: None" error.
788
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000789- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000790 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000791
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000792- Issue #3680: Reference cycles created through a dict, set or deque iterator
793 did not get collected.
794
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000795- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
796 where the tp_hash and tp_dict slots are both NULL.
797
Georg Brandlccc47b62008-12-28 11:44:14 +0000798- Issue #4759: None is now allowed as the first argument of
799 bytearray.translate(). It was always allowed for bytes.translate().
800
Skip Montanaro80072cb2008-12-23 03:51:14 +0000801- Added test case to ensure attempts to read from a file opened for writing
802 fail.
803
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000804- Issue #3106: Speedup some comparisons (str/str and int/int).
805
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000806- Issue #2183: Simplify and optimize bytecode for list, dict and set
807 comprehensions. Original patch for list comprehensions by Neal Norwitz.
808
Antoine Pitrou621601a2008-12-17 23:18:19 +0000809- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
810 print elapsed times, not only when some objects are uncollectable /
811 unreachable. Original patch by Neil Schemenauer.
812
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000813- Issue #3439: Add a bit_length method to int.
814
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000815- Issue #2173: When getting device encoding, check that return value of
816 nl_langinfo is not the empty string. This was causing silent build
817 failures on OS X.
818
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000819- Issue #4597: Fixed several opcodes that weren't always propagating
820 exceptions.
821
822- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000823 context manager returns a value that cannot be converted to a bool.
824
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000825- Issue #4445: Replace "sizeof(PyBytesObject)" with
826 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
827 bytes instances. On a typical machine this saves 3 bytes of memory
828 (on average) per allocation of a bytes instance.
829
Christian Heimesa872de52008-12-05 08:26:55 +0000830- Issue #4533: File read operation was dreadfully slow due to a slowly
831 growing read buffer. Fixed by using the same growth rate algorithm as
832 Python 2.x.
833
Antoine Pitrou5504e892008-12-06 21:27:53 +0000834- Issue #4509: Various issues surrounding resize of bytearray objects to
835 which there are buffer exports (e.g. memoryview instances).
836
Georg Brandlf9734072008-12-07 15:30:06 +0000837- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
838 method on file objects with closefd=False. The file descriptor is still
839 kept open but the file object behaves like a closed file. The ``FileIO``
840 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000841
Antoine Pitroubc420402008-12-07 20:14:49 +0000842- Issue #4569: Interpreter crash when mutating a memoryview with an item size
843 larger than 1.
844
Benjamin Peterson371ccfb2008-12-27 19:03:36 +0000845- Issue #4748: Lambda generators no longer return a value.

848
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000849- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
850 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
851 step. This avoids problems with counting UTF-8 bytes that ignores the effect
852 of using the replace error handler in PyUnicode_DecodeUTF8().
