604 a single ``\UXXXXXXXX``, regardless of whether the character is printable
605 or not. Also, the "backslashreplace" error handler now joins surrogate

636 output with no type specifier failed to match the str output:
637
638 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti25bc0192010-07-03 05:18:50 +0000644- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
645 start byte and the continuation byte(s) are now considered invalid, instead
646 of the number of bytes specified by the start byte.
647 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
648 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
649 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
650 Previous versions returned a single u'\ufffd'.

2283 to be like 'g' but with at least one decimal point and with a
2284 default precision of 12. Previously, the behavior the same but with
2285 a default precision of 6. This more closely matches str(), and
2286 reduces surprises when adding alignment flags to the empty
2287 presentation type. This also affects the new complex.__format__ in
2288 the same way.

Mark Dickinson33841c32009-05-01 15:37:04 +00002305- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2306 floats with absolute value over 1e50. Also remove length
2307 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2308 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00002310- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002311 format(complex(1, 2./3), '.5') now produces a sensible result.
2312
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002313- Issue #5864: Fix empty format code formatting for floats so that it
2314 never gives more than the requested number of significant digits.
2315
Eric Smith6dc46f52009-04-27 20:39:49 +00002316- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00002326- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2327 z involves nans, infs or negative zeros.
2328
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002329- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002330
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002331- Issue #1869 (and many duplicates): make round(x, n) correctly
2332 rounded for a float x, by using the decimal <-> binary conversions
2333 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2334 consistently agrees with format(x, '.2f').
2335
Benjamin Petersonae937c02009-04-18 20:54:08 +00002336- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

2340
Eric Smith35e84722009-04-16 20:21:28 +00002341- Issue #5515: str.format() type 'n' combined with commas and leading
2342 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002343
2344- Implement PEP 378, Format Specifier for Thousands Separator, for
2345 floats.
2346
Mark Dickinson3370cce2009-04-17 22:40:53 +00002347- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002348 1e11, not 1e12. This avoids printing 13 significant digits in
2349 situations where only 12 of them are correct. Example problem
2350 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2351 long time.)
2352
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002353- Issue #1580: On most platforms, use a 'short' float repr: for a
2354 finite float x, repr(x) now outputs a string based on the shortest
2355 sequence of decimal digits that rounds to x. Previous behaviour was
2356 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002357 Another minor difference is that the new repr switches to
2358 exponential notation at 1e16 instead of the previous 1e17; this
2359 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002360
2361 There's a new sys attribute sys.float_repr_style, which takes
2362 the value 'short' to indicate that we're using short float repr,
2363 and 'legacy' if the short float repr isn't available for one
2364 reason or another.
2365
2366 The float repr change involves incorporating David Gay's 'perfect
2367 rounding' code into the Python core (it's in Python/dtoa.c). As a
2368 secondary consequence, all string-to-float and float-to-string
2369 conversions (including all float formatting operations) will be
2370 correctly rounded on these platforms.
2371
Georg Brandl442d3b32010-08-01 22:33:12 +00002372 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002373 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002375- Issue #5759: float() didn't call __float__ on str subclasses.
2376
Georg Brandlabc38772009-04-12 15:51:51 +00002377- The string.maketrans() function is deprecated; there is a new static method
2378 maketrans() on the bytes and bytearray classes. This removes confusion about
2379 the types string.maketrans() is supposed to work with, and mirrors the
2380 methods available on the str class.
2381
R. David Murraydc6da8a2009-04-09 22:16:43 +00002382- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

2620 forever on incomplete input. That caused tarfile.open() to hang when used
2621 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2622 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002643 struct.error instead of returning b'\xff\xff\xff\xff'. The
2644 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

2670 rotating the object pointer by 4 bits to the right.
2671
Mark Dickinson87ec0852009-02-09 17:15:59 +00002672- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2673 it now forces its argument to double before testing for infinity.
2674
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002675- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002684
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002685- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002686 were suppressing all exceptions. These include list() and bytearray().
2687
Mark Dickinson1124e712009-01-28 21:25:58 +00002688- Issue #4707: round(x, n) now returns an integer if x is an integer.
2689 Previously it returned a float.
2690
Antoine Pitroub52ec782009-01-25 16:34:23 +00002691- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2692 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2693 evaluation loop is compiled with a new dispatch mechanism which gives
2694 speedups of up to 20%, depending on the system, on various benchmarks.
2695
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002696- Issue #4874: Most builtin decoders now reject unicode input.

2702
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002703- Issue #4838: When a module is deallocated, free the memory backing the
2704 optional module state data.
2705
Mark Dickinson8055afd2009-01-17 10:04:45 +00002706- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2707 type to (void *).
2708
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002709- Issue #4935: The overflow checking code in the expandtabs() method common
2710 to str, bytes and bytearray could be optimized away by the compiler, letting
2711 the interpreter segfault instead of raising an error.
2712
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002713- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2714 __next__ method.
2715
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002716- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2717 function no longer attempt to call the __long__ slot to convert an object
2718 to an integer. Only the __int__ and __trunc__ slots are examined.
2719
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002720- Issue #4893: Use NT threading on CE.
2721
Martin v. Löwisec59d042009-01-12 07:59:10 +00002722- Issue #4915: Port sysmodule to Windows CE.
2723
Antoine Pitrouab868312009-01-10 15:40:25 +00002724- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2725 common cases are optimized thanks to a dedicated fast path and a moderate
2726 amount of loop unrolling.
2727
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002728- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2729 collecting the oldest generation) so that allocating lots of objects without
2730 destroying them does not show quadratic performance. Based on a proposal by
2731 Martin von Löwis at
2732 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2733
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002734- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002735 having been closed (for instance, a read() call could return some
2736 previously buffered data). Patch by Dmitry Vasiliev.
2737
Antoine Pitrou05608432009-01-09 18:53:14 +00002738- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2739 flag to work properly. Furthermore, when specifying -u, the text stdout
2740 and stderr streams have line-by-line buffering enabled (the default being
2741 to buffer arbitrary chunks of data).
2742
Raymond Hettinger35631532009-01-09 03:58:09 +00002743- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2744 instead of ints (reducing its size from 4 to 8 times thereby reducing
2745 Python's overall memory).
2746
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002747- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2748 an existing .py counterpart, override the co_filename attributes of all
2749 code objects if the original filename is obsolete (which can happen if the
2750 file has been renamed, moved, or if it is accessed through different paths).
2751 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2752
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002753- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2754 one byte. Also fixes the meaning of len() so that it returns the number of
2755 items, rather than the size in bytes.
2756
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002757- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2758
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002759- Issue #4747: When the terminal does not use utf-8, executing a script with
2760 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2761
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002762- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002763 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002764
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002765- Issue #3680: Reference cycles created through a dict, set or deque iterator
2766 did not get collected.
2767
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002768- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2769 where the tp_hash and tp_dict slots are both NULL.
2770
Georg Brandlccc47b62008-12-28 11:44:14 +00002771- Issue #4759: None is now allowed as the first argument of
2772 bytearray.translate(). It was always allowed for bytes.translate().
2773
Skip Montanaro80072cb2008-12-23 03:51:14 +00002774- Added test case to ensure attempts to read from a file opened for writing
2775 fail.
2776
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002777- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002779- Issue #2183: Simplify and optimize bytecode for list, dict and set
2780 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2781
Antoine Pitrou621601a2008-12-17 23:18:19 +00002782- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2783 print elapsed times, not only when some objects are uncollectable /
2784 unreachable. Original patch by Neil Schemenauer.
2785
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002786- Issue #3439: Add a bit_length method to int.
2787
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002788- Issue #2173: When getting device encoding, check that return value of
2789 nl_langinfo is not the empty string. This was causing silent build
2790 failures on OS X.
2791
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002792- Issue #4597: Fixed several opcodes that weren't always propagating
2793 exceptions.
2794
2795- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002796 context manager returns a value that cannot be converted to a bool.
2797
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002798- Issue #4445: Replace "sizeof(PyBytesObject)" with
2799 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2800 bytes instances. On a typical machine this saves 3 bytes of memory
2801 (on average) per allocation of a bytes instance.
2802
Christian Heimesa872de52008-12-05 08:26:55 +00002803- Issue #4533: File read operation was dreadfully slow due to a slowly
2804 growing read buffer. Fixed by using the same growth rate algorithm as
2805 Python 2.x.
2806
Antoine Pitrou5504e892008-12-06 21:27:53 +00002807- Issue #4509: Various issues surrounding resize of bytearray objects to
2808 which there are buffer exports (e.g. memoryview instances).
2809
Georg Brandlf9734072008-12-07 15:30:06 +00002810- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2811 method on file objects with closefd=False. The file descriptor is still
2812 kept open but the file object behaves like a closed file. The ``FileIO``
2813 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002814
Antoine Pitroubc420402008-12-07 20:14:49 +00002815- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2821
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002822- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2823 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2824 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2825 of using the replace error handler in PyUnicode_DecodeUTF8().
