316 rejected; (2) parsing of strings representing infinities and nans
317 was locale aware; and (3) the interpretation of fromhex('-nan')
318 didn't match that of float('-nan').

421Core and Builtins
422-----------------
423
Mark Dickinson865e01a2009-05-07 16:37:01 +0000424- Issue #5914: Add new C API function PyOS_string_to_double, and
425 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
426
Eric Smith741191f2009-05-06 13:08:15 +0000427- Issue #3382: float.__format__, complex.__format__, and %-formatting
428 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
429 affects nan -> NAN and inf -> INF.
430
Mark Hammond5a607a32009-05-06 08:04:54 +0000431- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
432 in all operations, including splitdrive, split, etc. splitunc() now issues
433 a PendingDeprecation warning.
434
Eric Smith63376222009-05-05 14:04:18 +0000435- Issue #5920: For float.__format__, change the behavior with the
436 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
437 to be like 'g' but with at least one decimal point and with a
438 default precision of 12. Previously, the behavior the same but with
439 a default precision of 6. This more closely matches str(), and
440 reduces surprises when adding alignment flags to the empty
441 presentation type. This also affects the new complex.__format__ in
442 the same way.
443
Martin v. Löwis011e8422009-05-05 04:43:17 +0000444- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
445
R. David Murrayb18500d2009-05-04 22:59:07 +0000446- Issue #5890: in subclasses of 'property' the __doc__ attribute was
447 shadowed by classtype's, even if it was None. property now
448 inserts the __doc__ into the subclass instance __dict__.
449
Antoine Pitrou244651a2009-05-04 18:56:13 +0000450- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
451 sequences. Patch by Nick Barnes and Victor Stinner.
452
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000453- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000454
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000455- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
456 received a new method, detach(). detach() disconnects the underlying stream
457 from the buffer or text IO and returns it.
458
Mark Dickinson33841c32009-05-01 15:37:04 +0000459- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
460 floats with absolute value over 1e50. Also remove length
461 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
462 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000463
Eric Smith741191f2009-05-06 13:08:15 +0000464- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000465 format(complex(1, 2./3), '.5') now produces a sensible result.
466
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000467- Issue #5864: Fix empty format code formatting for floats so that it
468 never gives more than the requested number of significant digits.
469
Eric Smith6dc46f52009-04-27 20:39:49 +0000470- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
471 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
472
Eric Smithcc32a112009-04-26 21:35:14 +0000473- Issue #5835: Deprecate PyOS_ascii_formatd.
474
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000475- Issue #4971: Fix titlecase for characters that are their own
476 titlecase, but not their own uppercase.
477
Benjamin Peterson193152c2009-04-25 01:08:45 +0000478- Issue #5283: Setting __class__ in __del__ caused a segfault.
479
Mark Dickinsonad476da2009-04-23 19:14:16 +0000480- Issue #5816: complex(repr(z)) now recovers z exactly, even when
481 z involves nans, infs or negative zeros.
482
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000483- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000484
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000485- Issue #1869 (and many duplicates): make round(x, n) correctly
486 rounded for a float x, by using the decimal <-> binary conversions
487 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
488 consistently agrees with format(x, '.2f').
489
Benjamin Petersonae937c02009-04-18 20:54:08 +0000490- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
491 some builtin types.
492
Eric Smith0923d1d2009-04-16 20:16:10 +0000493- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
494
Eric Smith35e84722009-04-16 20:21:28 +0000495- Issue #5515: str.format() type 'n' combined with commas and leading
496 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000497
498- Implement PEP 378, Format Specifier for Thousands Separator, for
499 floats.
500
Mark Dickinson3370cce2009-04-17 22:40:53 +0000501- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000502 1e11, not 1e12. This avoids printing 13 significant digits in
503 situations where only 12 of them are correct. Example problem
504 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
505 long time.)
506
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000507- Issue #1580: On most platforms, use a 'short' float repr: for a
508 finite float x, repr(x) now outputs a string based on the shortest
509 sequence of decimal digits that rounds to x. Previous behaviour was
510 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000511 Another minor difference is that the new repr switches to
512 exponential notation at 1e16 instead of the previous 1e17; this
513 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000514
515 There's a new sys attribute sys.float_repr_style, which takes
516 the value 'short' to indicate that we're using short float repr,
517 and 'legacy' if the short float repr isn't available for one
518 reason or another.
519
520 The float repr change involves incorporating David Gay's 'perfect
521 rounding' code into the Python core (it's in Python/dtoa.c). As a
522 secondary consequence, all string-to-float and float-to-string
523 conversions (including all float formatting operations) will be
524 correctly rounded on these platforms.
525
526 See issue 1580 discussions for details of platforms for which
527 this change does not apply.
528
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000529- Issue #5759: float() didn't call __float__ on str subclasses.
530
Georg Brandlabc38772009-04-12 15:51:51 +0000531- The string.maketrans() function is deprecated; there is a new static method
532 maketrans() on the bytes and bytearray classes. This removes confusion about
533 the types string.maketrans() is supposed to work with, and mirrors the
534 methods available on the str class.
535
R. David Murraydc6da8a2009-04-09 22:16:43 +0000536- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
537 its clarity and its speed.
538
Matthias Klose091c7b12009-04-07 13:24:27 +0000539- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
540 to avoid compiler warnings.
541
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000542- Issue #3739: The unicode-internal encoder now reports the number of characters
543 consumed like any other encoder (instead of the number of bytes).

774 forever on incomplete input. That caused tarfile.open() to hang when used
775 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
776 partial bzip2 compressed data.
777
Mark Dickinson79f52032009-03-17 23:12:51 +0000778- Issue #2110: Add support for thousands separator and 'n' type

893 flag to work properly. Furthermore, when specifying -u, the text stdout
894 and stderr streams have line-by-line buffering enabled (the default being
895 to buffer arbitrary chunks of data).
896
Raymond Hettinger35631532009-01-09 03:58:09 +0000897- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
898 instead of ints (reducing its size from 4 to 8 times thereby reducing
899 Python's overall memory).
