16 output with no type specifier failed to match the str output:
17
18 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
19 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
20

Ezio Melotti25bc0192010-07-03 05:18:50 +000024- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
25 start byte and the continuation byte(s) are now considered invalid, instead
26 of the number of bytes specified by the start byte.
27 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
28 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
29 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
30 Previous versions returned a single u'\ufffd'.

Antoine Pitrouc2203f92010-04-24 22:07:51 +0000331- Issue #8524: When creating an SSL socket, the timeout value of the
332 original socket wasn't retained (instead, a socket with a positive timeout
333 would be turned into a non-blocking SSL socket).
334
Antoine Pitrouec146182010-04-24 21:30:20 +0000335- Issue #5103: SSL handshake would ignore the socket timeout and block
336 indefinitely if the other end didn't respond.
337
338- The do_handshake() method of SSL objects now adjusts the blocking mode of
339 the SSL structure if necessary (as other methods already do).
340
Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000341- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
342 a non-infinite timeout. Also make that method friendlier with applications
343 wanting to continue using the socket in clear-text mode, by disabling
344 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

1279 was locale aware; and (3) the interpretation of fromhex('-nan')
1280 didn't match that of float('-nan').

Antoine Pitroue4501852009-05-14 18:55:55 +00001330- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1331 library. This means, for example, that opening an UTF-16 text file in

1384-----------------
1385
Mark Dickinson865e01a2009-05-07 16:37:01 +00001386- Issue #5914: Add new C API function PyOS_string_to_double, and
1387 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1388
Eric Smith741191f2009-05-06 13:08:15 +00001389- Issue #3382: float.__format__, complex.__format__, and %-formatting
1390 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1391 affects nan -> NAN and inf -> INF.
1392
Mark Hammond5a607a32009-05-06 08:04:54 +00001393- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1394 in all operations, including splitdrive, split, etc. splitunc() now issues
1395 a PendingDeprecation warning.
1396
Eric Smith63376222009-05-05 14:04:18 +00001397- Issue #5920: For float.__format__, change the behavior with the
1398 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1399 to be like 'g' but with at least one decimal point and with a
1400 default precision of 12. Previously, the behavior the same but with
1401 a default precision of 6. This more closely matches str(), and
1402 reduces surprises when adding alignment flags to the empty
1403 presentation type. This also affects the new complex.__format__ in
1404 the same way.
1405
Martin v. Löwis011e8422009-05-05 04:43:17 +00001406- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1407
R. David Murrayb18500d2009-05-04 22:59:07 +00001408- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1409 shadowed by classtype's, even if it was None. property now
1410 inserts the __doc__ into the subclass instance __dict__.
1411
Antoine Pitrou244651a2009-05-04 18:56:13 +00001412- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1413 sequences. Patch by Nick Barnes and Victor Stinner.
1414
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001415- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001416
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001417- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1418 received a new method, detach(). detach() disconnects the underlying stream
1419 from the buffer or text IO and returns it.
1420
Mark Dickinson33841c32009-05-01 15:37:04 +00001421- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1422 floats with absolute value over 1e50. Also remove length
1423 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1424 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001425
Eric Smith741191f2009-05-06 13:08:15 +00001426- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001427 format(complex(1, 2./3), '.5') now produces a sensible result.
1428
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001429- Issue #5864: Fix empty format code formatting for floats so that it
1430 never gives more than the requested number of significant digits.
1431
Eric Smith6dc46f52009-04-27 20:39:49 +00001432- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1438 titlecase, but not their own uppercase.
1439
Benjamin Peterson193152c2009-04-25 01:08:45 +00001440- Issue #5283: Setting __class__ in __del__ caused a segfault.
1441
Mark Dickinsonad476da2009-04-23 19:14:16 +00001442- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1443 z involves nans, infs or negative zeros.
1444
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001445- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001446
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001447- Issue #1869 (and many duplicates): make round(x, n) correctly
1448 rounded for a float x, by using the decimal <-> binary conversions
1449 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1450 consistently agrees with format(x, '.2f').
1451
Benjamin Petersonae937c02009-04-18 20:54:08 +00001452- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1453 some builtin types.
1454
Eric Smith0923d1d2009-04-16 20:16:10 +00001455- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1456
Eric Smith35e84722009-04-16 20:21:28 +00001457- Issue #5515: str.format() type 'n' combined with commas and leading
1458 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001459
1460- Implement PEP 378, Format Specifier for Thousands Separator, for
1461 floats.
1462
Mark Dickinson3370cce2009-04-17 22:40:53 +00001463- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001464 1e11, not 1e12. This avoids printing 13 significant digits in
1465 situations where only 12 of them are correct. Example problem
1466 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1467 long time.)
1468
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001469- Issue #1580: On most platforms, use a 'short' float repr: for a
1470 finite float x, repr(x) now outputs a string based on the shortest
1471 sequence of decimal digits that rounds to x. Previous behaviour was
1472 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001473 Another minor difference is that the new repr switches to
1474 exponential notation at 1e16 instead of the previous 1e17; this
1475 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001476
1477 There's a new sys attribute sys.float_repr_style, which takes
1478 the value 'short' to indicate that we're using short float repr,
1479 and 'legacy' if the short float repr isn't available for one
1480 reason or another.
1481
1482 The float repr change involves incorporating David Gay's 'perfect
1483 rounding' code into the Python core (it's in Python/dtoa.c). As a
1484 secondary consequence, all string-to-float and float-to-string
1485 conversions (including all float formatting operations) will be
1486 correctly rounded on these platforms.
1487
Georg Brandl442d3b32010-08-01 22:33:12 +00001488 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001489 this change does not apply.
1490
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001491- Issue #5759: float() didn't call __float__ on str subclasses.
1492
Georg Brandlabc38772009-04-12 15:51:51 +00001493- The string.maketrans() function is deprecated; there is a new static method
1494 maketrans() on the bytes and bytearray classes. This removes confusion about
1495 the types string.maketrans() is supposed to work with, and mirrors the
1496 methods available on the str class.
1497
R. David Murraydc6da8a2009-04-09 22:16:43 +00001498- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1786 rotating the object pointer by 4 bits to the right.
1787
Mark Dickinson87ec0852009-02-09 17:15:59 +00001788- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001800
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001801- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001802 were suppressing all exceptions. These include list() and bytearray().

1806
Antoine Pitroub52ec782009-01-25 16:34:23 +00001807- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1808 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1809 evaluation loop is compiled with a new dispatch mechanism which gives
1810 speedups of up to 20%, depending on the system, on various benchmarks.
1811
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001812- Issue #4874: Most builtin decoders now reject unicode input.

1818
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001819- Issue #4838: When a module is deallocated, free the memory backing the
1820 optional module state data.
1821
Mark Dickinson8055afd2009-01-17 10:04:45 +00001822- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1823 type to (void *).
1824
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001825- Issue #4935: The overflow checking code in the expandtabs() method common
1826 to str, bytes and bytearray could be optimized away by the compiler, letting
1827 the interpreter segfault instead of raising an error.
1828
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001829- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1830 __next__ method.
1831
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001832- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1833 function no longer attempt to call the __long__ slot to convert an object
1834 to an integer. Only the __int__ and __trunc__ slots are examined.
1835
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001836- Issue #4893: Use NT threading on CE.
1837
Martin v. Löwisec59d042009-01-12 07:59:10 +00001838- Issue #4915: Port sysmodule to Windows CE.
1839
Antoine Pitrouab868312009-01-10 15:40:25 +00001840- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1841 common cases are optimized thanks to a dedicated fast path and a moderate
1842 amount of loop unrolling.
1843
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001844- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1845 collecting the oldest generation) so that allocating lots of objects without
1846 destroying them does not show quadratic performance. Based on a proposal by
1847 Martin von Löwis at
1848 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1849
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001850- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001851 having been closed (for instance, a read() call could return some
1852 previously buffered data). Patch by Dmitry Vasiliev.
1853
Antoine Pitrou05608432009-01-09 18:53:14 +00001854- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1855 flag to work properly. Furthermore, when specifying -u, the text stdout
1856 and stderr streams have line-by-line buffering enabled (the default being
1857 to buffer arbitrary chunks of data).
1858
Raymond Hettinger35631532009-01-09 03:58:09 +00001859- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1860 instead of ints (reducing its size from 4 to 8 times thereby reducing
1861 Python's overall memory).
1862
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001863- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1864 an existing .py counterpart, override the co_filename attributes of all
1865 code objects if the original filename is obsolete (which can happen if the
1866 file has been renamed, moved, or if it is accessed through different paths).
1867 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1868
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001869- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1870 one byte. Also fixes the meaning of len() so that it returns the number of
1871 items, rather than the size in bytes.
1872
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001873- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1874
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001875- Issue #4747: When the terminal does not use utf-8, executing a script with
1876 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1877
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001878- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001879 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001880
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001881- Issue #3680: Reference cycles created through a dict, set or deque iterator
1882 did not get collected.
1883
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001884- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1885 where the tp_hash and tp_dict slots are both NULL.
1886
Georg Brandlccc47b62008-12-28 11:44:14 +00001887- Issue #4759: None is now allowed as the first argument of
1888 bytearray.translate(). It was always allowed for bytes.translate().
1889
Skip Montanaro80072cb2008-12-23 03:51:14 +00001890- Added test case to ensure attempts to read from a file opened for writing
1891 fail.
1892
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001893- Issue #3106: Speedup some comparisons (str/str and int/int).

1896 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1897
Antoine Pitrou621601a2008-12-17 23:18:19 +00001898- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1899 print elapsed times, not only when some objects are uncollectable /
1900 unreachable. Original patch by Neil Schemenauer.
1901
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001902- Issue #3439: Add a bit_length method to int.
1903
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001904- Issue #2173: When getting device encoding, check that return value of
1905 nl_langinfo is not the empty string. This was causing silent build
1906 failures on OS X.
1907
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001908- Issue #4597: Fixed several opcodes that weren't always propagating
1909 exceptions.
1910
1911- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001912 context manager returns a value that cannot be converted to a bool.
1913
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001914- Issue #4445: Replace "sizeof(PyBytesObject)" with
1915 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1916 bytes instances. On a typical machine this saves 3 bytes of memory
1917 (on average) per allocation of a bytes instance.
1918
Christian Heimesa872de52008-12-05 08:26:55 +00001919- Issue #4533: File read operation was dreadfully slow due to a slowly
1920 growing read buffer. Fixed by using the same growth rate algorithm as
1921 Python 2.x.
1922
Antoine Pitrou5504e892008-12-06 21:27:53 +00001923- Issue #4509: Various issues surrounding resize of bytearray objects to
1924 which there are buffer exports (e.g. memoryview instances).
1925
Georg Brandlf9734072008-12-07 15:30:06 +00001926- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1927 method on file objects with closefd=False. The file descriptor is still
1928 kept open but the file object behaves like a closed file. The ``FileIO``
1929 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001930
Antoine Pitroubc420402008-12-07 20:14:49 +00001931- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1932 larger than 1.

1937
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001938- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1939 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1940 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1941 of using the replace error handler in PyUnicode_DecodeUTF8().
