133 was locale aware; and (3) the interpretation of fromhex('-nan')
134 didn't match that of float('-nan').

187 empty.
188
R. David Murray74b89242009-05-13 17:33:03 +0000189- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

239
Mark Dickinson865e01a2009-05-07 16:37:01 +0000240- Issue #5914: Add new C API function PyOS_string_to_double, and
241 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
242
Eric Smith741191f2009-05-06 13:08:15 +0000243- Issue #3382: float.__format__, complex.__format__, and %-formatting
244 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
245 affects nan -> NAN and inf -> INF.
246
Mark Hammond5a607a32009-05-06 08:04:54 +0000247- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
248 in all operations, including splitdrive, split, etc. splitunc() now issues
249 a PendingDeprecation warning.
250
Eric Smith63376222009-05-05 14:04:18 +0000251- Issue #5920: For float.__format__, change the behavior with the
252 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
253 to be like 'g' but with at least one decimal point and with a
254 default precision of 12. Previously, the behavior the same but with
255 a default precision of 6. This more closely matches str(), and
256 reduces surprises when adding alignment flags to the empty
257 presentation type. This also affects the new complex.__format__ in
258 the same way.
259
Martin v. Löwis011e8422009-05-05 04:43:17 +0000260- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

268
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000269- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000270
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000271- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
272 received a new method, detach(). detach() disconnects the underlying stream
273 from the buffer or text IO and returns it.
274
Mark Dickinson33841c32009-05-01 15:37:04 +0000275- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
276 floats with absolute value over 1e50. Also remove length
277 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
278 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000279
Eric Smith741191f2009-05-06 13:08:15 +0000280- Issue #1588: Add complex.__format__. For example,

284 never gives more than the requested number of significant digits.
285
Eric Smith6dc46f52009-04-27 20:39:49 +0000286- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
287 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
288

295
Mark Dickinsonad476da2009-04-23 19:14:16 +0000296- Issue #5816: complex(repr(z)) now recovers z exactly, even when
297 z involves nans, infs or negative zeros.

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000301- Issue #1869 (and many duplicates): make round(x, n) correctly
302 rounded for a float x, by using the decimal <-> binary conversions
303 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
304 consistently agrees with format(x, '.2f').
305
Benjamin Petersonae937c02009-04-18 20:54:08 +0000306- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

312 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000313
314- Implement PEP 378, Format Specifier for Thousands Separator, for
315 floats.

Mark Dickinson3370cce2009-04-17 22:40:53 +0000317- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000318 1e11, not 1e12. This avoids printing 13 significant digits in
319 situations where only 12 of them are correct. Example problem
320 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
321 long time.)
322
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000323- Issue #1580: On most platforms, use a 'short' float repr: for a
324 finite float x, repr(x) now outputs a string based on the shortest
325 sequence of decimal digits that rounds to x. Previous behaviour was
326 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000327 Another minor difference is that the new repr switches to
328 exponential notation at 1e16 instead of the previous 1e17; this
329 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000330
331 There's a new sys attribute sys.float_repr_style, which takes
332 the value 'short' to indicate that we're using short float repr,
333 and 'legacy' if the short float repr isn't available for one
334 reason or another.
335
336 The float repr change involves incorporating David Gay's 'perfect
337 rounding' code into the Python core (it's in Python/dtoa.c). As a
338 secondary consequence, all string-to-float and float-to-string
339 conversions (including all float formatting operations) will be
340 correctly rounded on these platforms.
341
342 See issue 1580 discussions for details of platforms for which
343 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000345- Issue #5759: float() didn't call __float__ on str subclasses.
346
Georg Brandlabc38772009-04-12 15:51:51 +0000347- The string.maketrans() function is deprecated; there is a new static method
348 maketrans() on the bytes and bytearray classes. This removes confusion about
349 the types string.maketrans() is supposed to work with, and mirrors the
350 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000655- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000656 were suppressing all exceptions. These include list() and bytearray().
657
Mark Dickinson1124e712009-01-28 21:25:58 +0000658- Issue #4707: round(x, n) now returns an integer if x is an integer.
659 Previously it returned a float.
660
Antoine Pitroub52ec782009-01-25 16:34:23 +0000661- Issue #4753: By enabling a configure option named '--with-computed-gotos'
662 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
663 evaluation loop is compiled with a new dispatch mechanism which gives
664 speedups of up to 20%, depending on the system, on various benchmarks.

677 type to (void *).
678
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000679- Issue #4935: The overflow checking code in the expandtabs() method common
680 to str, bytes and bytearray could be optimized away by the compiler, letting
681 the interpreter segfault instead of raising an error.
682
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000683- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrouab868312009-01-10 15:40:25 +0000694- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
695 common cases are optimized thanks to a dedicated fast path and a moderate
696 amount of loop unrolling.
697
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000698- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
699 collecting the oldest generation) so that allocating lots of objects without
700 destroying them does not show quadratic performance. Based on a proposal by
701 Martin von Löwis at
702 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
703
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000704- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000705 having been closed (for instance, a read() call could return some
706 previously buffered data). Patch by Dmitry Vasiliev.
707
Antoine Pitrou05608432009-01-09 18:53:14 +0000708- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
709 flag to work properly. Furthermore, when specifying -u, the text stdout
710 and stderr streams have line-by-line buffering enabled (the default being
711 to buffer arbitrary chunks of data).
712
Raymond Hettinger35631532009-01-09 03:58:09 +0000713- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
714 instead of ints (reducing its size from 4 to 8 times thereby reducing
715 Python's overall memory).
716
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000717- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
718 an existing .py counterpart, override the co_filename attributes of all
719 code objects if the original filename is obsolete (which can happen if the
720 file has been renamed, moved, or if it is accessed through different paths).
721 Patch by Ziga Seilnacht and Jean-Paul Calderone.
722
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000723- Issue #4580: Fix slicing of memoryviews when the item size is greater than
724 one byte. Also fixes the meaning of len() so that it returns the number of
725 items, rather than the size in bytes.
726
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000727- Issue #4075: Use OutputDebugStringW in Py_FatalError.

767
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000768- Issue #4445: Replace "sizeof(PyBytesObject)" with
769 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
770 bytes instances. On a typical machine this saves 3 bytes of memory
771 (on average) per allocation of a bytes instance.
772
Christian Heimesa872de52008-12-05 08:26:55 +0000773- Issue #4533: File read operation was dreadfully slow due to a slowly
774 growing read buffer. Fixed by using the same growth rate algorithm as
775 Python 2.x.
776
Antoine Pitrou5504e892008-12-06 21:27:53 +0000777- Issue #4509: Various issues surrounding resize of bytearray objects to
778 which there are buffer exports (e.g. memoryview instances).
779
Georg Brandlf9734072008-12-07 15:30:06 +0000780- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
781 method on file objects with closefd=False. The file descriptor is still
782 kept open but the file object behaves like a closed file. The ``FileIO``
783 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000784
Antoine Pitroubc420402008-12-07 20:14:49 +0000785- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +0000792- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
793 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
794 step. This avoids problems with counting UTF-8 bytes that ignores the effect
795 of using the replace error handler in PyUnicode_DecodeUTF8().
