337 (1) inf and nan strings with trailing whitespace were incorrectly
338 rejected; (2) parsing of strings representing infinities and nans
339 was locale aware; and (3) the interpretation of fromhex('-nan')
340 didn't match that of float('-nan').

443Core and Builtins
444-----------------
445
Mark Dickinson865e01a2009-05-07 16:37:01 +0000446- Issue #5914: Add new C API function PyOS_string_to_double, and
447 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
448
Eric Smith741191f2009-05-06 13:08:15 +0000449- Issue #3382: float.__format__, complex.__format__, and %-formatting
450 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
451 affects nan -> NAN and inf -> INF.
452
Mark Hammond5a607a32009-05-06 08:04:54 +0000453- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
454 in all operations, including splitdrive, split, etc. splitunc() now issues
455 a PendingDeprecation warning.
456
Eric Smith63376222009-05-05 14:04:18 +0000457- Issue #5920: For float.__format__, change the behavior with the
458 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
459 to be like 'g' but with at least one decimal point and with a
460 default precision of 12. Previously, the behavior the same but with
461 a default precision of 6. This more closely matches str(), and
462 reduces surprises when adding alignment flags to the empty
463 presentation type. This also affects the new complex.__format__ in
464 the same way.
465
Martin v. Löwis011e8422009-05-05 04:43:17 +0000466- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
467
R. David Murrayb18500d2009-05-04 22:59:07 +0000468- Issue #5890: in subclasses of 'property' the __doc__ attribute was
469 shadowed by classtype's, even if it was None. property now
470 inserts the __doc__ into the subclass instance __dict__.
471
Antoine Pitrou244651a2009-05-04 18:56:13 +0000472- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
473 sequences. Patch by Nick Barnes and Victor Stinner.
474
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000475- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000476
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000477- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
478 received a new method, detach(). detach() disconnects the underlying stream
479 from the buffer or text IO and returns it.
480
Mark Dickinson33841c32009-05-01 15:37:04 +0000481- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
482 floats with absolute value over 1e50. Also remove length
483 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
484 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000485
Eric Smith741191f2009-05-06 13:08:15 +0000486- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000487 format(complex(1, 2./3), '.5') now produces a sensible result.
488
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000489- Issue #5864: Fix empty format code formatting for floats so that it
490 never gives more than the requested number of significant digits.
491
Eric Smith6dc46f52009-04-27 20:39:49 +0000492- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
493 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
494
Eric Smithcc32a112009-04-26 21:35:14 +0000495- Issue #5835: Deprecate PyOS_ascii_formatd.
496
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000497- Issue #4971: Fix titlecase for characters that are their own
498 titlecase, but not their own uppercase.
499
Benjamin Peterson193152c2009-04-25 01:08:45 +0000500- Issue #5283: Setting __class__ in __del__ caused a segfault.
501
Mark Dickinsonad476da2009-04-23 19:14:16 +0000502- Issue #5816: complex(repr(z)) now recovers z exactly, even when
503 z involves nans, infs or negative zeros.
504
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000505- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000506
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000507- Issue #1869 (and many duplicates): make round(x, n) correctly
508 rounded for a float x, by using the decimal <-> binary conversions
509 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
510 consistently agrees with format(x, '.2f').
511
Benjamin Petersonae937c02009-04-18 20:54:08 +0000512- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
513 some builtin types.
514
Eric Smith0923d1d2009-04-16 20:16:10 +0000515- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
516
Eric Smith35e84722009-04-16 20:21:28 +0000517- Issue #5515: str.format() type 'n' combined with commas and leading
518 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000519
520- Implement PEP 378, Format Specifier for Thousands Separator, for
521 floats.
522
Mark Dickinson3370cce2009-04-17 22:40:53 +0000523- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000524 1e11, not 1e12. This avoids printing 13 significant digits in
525 situations where only 12 of them are correct. Example problem
526 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
527 long time.)
528
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000529- Issue #1580: On most platforms, use a 'short' float repr: for a
530 finite float x, repr(x) now outputs a string based on the shortest
531 sequence of decimal digits that rounds to x. Previous behaviour was
532 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000533 Another minor difference is that the new repr switches to
534 exponential notation at 1e16 instead of the previous 1e17; this
535 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000536
537 There's a new sys attribute sys.float_repr_style, which takes
538 the value 'short' to indicate that we're using short float repr,
539 and 'legacy' if the short float repr isn't available for one
540 reason or another.
541
542 The float repr change involves incorporating David Gay's 'perfect
543 rounding' code into the Python core (it's in Python/dtoa.c). As a
544 secondary consequence, all string-to-float and float-to-string
545 conversions (including all float formatting operations) will be
546 correctly rounded on these platforms.
547
548 See issue 1580 discussions for details of platforms for which
549 this change does not apply.
550
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000551- Issue #5759: float() didn't call __float__ on str subclasses.
552
Georg Brandlabc38772009-04-12 15:51:51 +0000553- The string.maketrans() function is deprecated; there is a new static method
554 maketrans() on the bytes and bytearray classes. This removes confusion about
555 the types string.maketrans() is supposed to work with, and mirrors the
556 methods available on the str class.
557
R. David Murraydc6da8a2009-04-09 22:16:43 +0000558- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
559 its clarity and its speed.
560
Matthias Klose091c7b12009-04-07 13:24:27 +0000561- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
562 to avoid compiler warnings.
563
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000564- Issue #3739: The unicode-internal encoder now reports the number of characters
565 consumed like any other encoder (instead of the number of bytes).

721
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000722- Issue #4688: Add a heuristic so that tuples and dicts containing only
723 untrackable objects are not tracked by the garbage collector. This can
724 reduce the size of collections and therefore the garbage collection overhead
725 on long-running programs, depending on their particular use of datatypes.

796 forever on incomplete input. That caused tarfile.open() to hang when used
797 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
798 partial bzip2 compressed data.
799
Mark Dickinson79f52032009-03-17 23:12:51 +0000800- Issue #2110: Add support for thousands separator and 'n' type

915 flag to work properly. Furthermore, when specifying -u, the text stdout
916 and stderr streams have line-by-line buffering enabled (the default being
917 to buffer arbitrary chunks of data).
918
Raymond Hettinger35631532009-01-09 03:58:09 +0000919- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
920 instead of ints (reducing its size from 4 to 8 times thereby reducing
921 Python's overall memory).

Antoine Pitrou08838b62009-01-21 00:55:13 +00001306- Issue #5008: When a file is opened in append mode with the new IO library,
1307 do an explicit seek to the end of file (so that e.g. tell() returns the
