39 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
40 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

346 Decimal operation raises multiple signals and more than one of those
347 signals is trapped, the specification determines the order in which
348 the signals should be handled. In many cases this order wasn't
349 being followed, leading to the wrong Python exception being raised.

379 event loop started running. This also fixes the occasional freezes
380 witnessed in test_httpservers.
381
Antoine Pitrouc2203f92010-04-24 22:07:51 +0000382- Issue #8524: When creating an SSL socket, the timeout value of the
383 original socket wasn't retained (instead, a socket with a positive timeout
384 would be turned into a non-blocking SSL socket).
385
Antoine Pitrouec146182010-04-24 21:30:20 +0000386- Issue #5103: SSL handshake would ignore the socket timeout and block
387 indefinitely if the other end didn't respond.
388
389- The do_handshake() method of SSL objects now adjusts the blocking mode of
390 the SSL structure if necessary (as other methods already do).

Antoine Pitrou5a1c4d12010-04-23 21:11:10 +0000392- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
393 a non-infinite timeout. Also make that method friendlier with applications
394 wanting to continue using the socket in clear-text mode, by disabling
395 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

1464 to be like 'g' but with at least one decimal point and with a
1465 default precision of 12. Previously, the behavior the same but with
1466 a default precision of 6. This more closely matches str(), and
1467 reduces surprises when adding alignment flags to the empty
1468 presentation type. This also affects the new complex.__format__ in
1469 the same way.

Martin v. Löwis011e8422009-05-05 04:43:17 +00001471- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00001473- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1474 shadowed by classtype's, even if it was None. property now
1475 inserts the __doc__ into the subclass instance __dict__.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001482- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1483 received a new method, detach(). detach() disconnects the underlying stream
1484 from the buffer or text IO and returns it.
1485
Mark Dickinson33841c32009-05-01 15:37:04 +00001486- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1487 floats with absolute value over 1e50. Also remove length
1488 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1489 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001491- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001492 format(complex(1, 2./3), '.5') now produces a sensible result.
1493
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001494- Issue #5864: Fix empty format code formatting for floats so that it
1495 never gives more than the requested number of significant digits.
1496
Eric Smith6dc46f52009-04-27 20:39:49 +00001497- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00001507- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1508 z involves nans, infs or negative zeros.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001512- Issue #1869 (and many duplicates): make round(x, n) correctly
1513 rounded for a float x, by using the decimal <-> binary conversions
1514 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1515 consistently agrees with format(x, '.2f').
1516
Benjamin Petersonae937c02009-04-18 20:54:08 +00001517- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1519
Eric Smith0923d1d2009-04-16 20:16:10 +00001520- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1521
Eric Smith35e84722009-04-16 20:21:28 +00001522- Issue #5515: str.format() type 'n' combined with commas and leading
1523 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001524
1525- Implement PEP 378, Format Specifier for Thousands Separator, for
1526 floats.
1527
Mark Dickinson3370cce2009-04-17 22:40:53 +00001528- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001529 1e11, not 1e12. This avoids printing 13 significant digits in
1530 situations where only 12 of them are correct. Example problem
1531 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1532 long time.)
1533
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001534- Issue #1580: On most platforms, use a 'short' float repr: for a
1535 finite float x, repr(x) now outputs a string based on the shortest
1536 sequence of decimal digits that rounds to x. Previous behaviour was
1537 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001538 Another minor difference is that the new repr switches to
1539 exponential notation at 1e16 instead of the previous 1e17; this
1540 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001541
1542 There's a new sys attribute sys.float_repr_style, which takes
1543 the value 'short' to indicate that we're using short float repr,
1544 and 'legacy' if the short float repr isn't available for one
1545 reason or another.
1546
1547 The float repr change involves incorporating David Gay's 'perfect
1548 rounding' code into the Python core (it's in Python/dtoa.c). As a
1549 secondary consequence, all string-to-float and float-to-string
1550 conversions (including all float formatting operations) will be
1551 correctly rounded on these platforms.
1552
Georg Brandl442d3b32010-08-01 22:33:12 +00001553 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001554 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001556- Issue #5759: float() didn't call __float__ on str subclasses.
1557
Georg Brandlabc38772009-04-12 15:51:51 +00001558- The string.maketrans() function is deprecated; there is a new static method
1559 maketrans() on the bytes and bytearray classes. This removes confusion about
1560 the types string.maketrans() is supposed to work with, and mirrors the
1561 methods available on the str class.
1562
R. David Murraydc6da8a2009-04-09 22:16:43 +00001563- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1851 rotating the object pointer by 4 bits to the right.
1852
Mark Dickinson87ec0852009-02-09 17:15:59 +00001853- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1854 it now forces its argument to double before testing for infinity.
1855
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001856- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001865
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001866- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001867 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001869- Issue #4707: round(x, n) now returns an integer if x is an integer.
1870 Previously it returned a float.
1871
Antoine Pitroub52ec782009-01-25 16:34:23 +00001872- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1873 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1874 evaluation loop is compiled with a new dispatch mechanism which gives
1875 speedups of up to 20%, depending on the system, on various benchmarks.
1876
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001877- Issue #4874: Most builtin decoders now reject unicode input.

1883
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001884- Issue #4838: When a module is deallocated, free the memory backing the
1885 optional module state data.
1886
Mark Dickinson8055afd2009-01-17 10:04:45 +00001887- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1888 type to (void *).
1889
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001890- Issue #4935: The overflow checking code in the expandtabs() method common
1891 to str, bytes and bytearray could be optimized away by the compiler, letting
1892 the interpreter segfault instead of raising an error.
1893
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001894- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1895 __next__ method.
1896
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001897- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1898 function no longer attempt to call the __long__ slot to convert an object
1899 to an integer. Only the __int__ and __trunc__ slots are examined.
1900
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001901- Issue #4893: Use NT threading on CE.
1902
Martin v. Löwisec59d042009-01-12 07:59:10 +00001903- Issue #4915: Port sysmodule to Windows CE.
1904
Antoine Pitrouab868312009-01-10 15:40:25 +00001905- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1906 common cases are optimized thanks to a dedicated fast path and a moderate
1907 amount of loop unrolling.
1908
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001909- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1910 collecting the oldest generation) so that allocating lots of objects without
1911 destroying them does not show quadratic performance. Based on a proposal by
1912 Martin von Löwis at
1913 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1914
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001915- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001916 having been closed (for instance, a read() call could return some
1917 previously buffered data). Patch by Dmitry Vasiliev.
1918
Antoine Pitrou05608432009-01-09 18:53:14 +00001919- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1920 flag to work properly. Furthermore, when specifying -u, the text stdout
1921 and stderr streams have line-by-line buffering enabled (the default being
1922 to buffer arbitrary chunks of data).
1923
Raymond Hettinger35631532009-01-09 03:58:09 +00001924- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1925 instead of ints (reducing its size from 4 to 8 times thereby reducing
1926 Python's overall memory).
1927
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001928- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1929 an existing .py counterpart, override the co_filename attributes of all
1930 code objects if the original filename is obsolete (which can happen if the
1931 file has been renamed, moved, or if it is accessed through different paths).
1932 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1933
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001934- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1935 one byte. Also fixes the meaning of len() so that it returns the number of
1936 items, rather than the size in bytes.
1937
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001938- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1939
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001940- Issue #4747: When the terminal does not use utf-8, executing a script with
1941 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1942
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001943- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001944 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001945
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001946- Issue #3680: Reference cycles created through a dict, set or deque iterator
1947 did not get collected.
1948
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001949- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1950 where the tp_hash and tp_dict slots are both NULL.
1951
Georg Brandlccc47b62008-12-28 11:44:14 +00001952- Issue #4759: None is now allowed as the first argument of
1953 bytearray.translate(). It was always allowed for bytes.translate().
1954
Skip Montanaro80072cb2008-12-23 03:51:14 +00001955- Added test case to ensure attempts to read from a file opened for writing
1956 fail.
1957
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001958- Issue #3106: Speedup some comparisons (str/str and int/int).

1961 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1962
Antoine Pitrou621601a2008-12-17 23:18:19 +00001963- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1964 print elapsed times, not only when some objects are uncollectable /
1965 unreachable. Original patch by Neil Schemenauer.
1966
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001967- Issue #3439: Add a bit_length method to int.
1968
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001969- Issue #2173: When getting device encoding, check that return value of
1970 nl_langinfo is not the empty string. This was causing silent build
1971 failures on OS X.
1972
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001973- Issue #4597: Fixed several opcodes that weren't always propagating
1974 exceptions.
1975
1976- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001977 context manager returns a value that cannot be converted to a bool.
1978
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001979- Issue #4445: Replace "sizeof(PyBytesObject)" with
1980 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1981 bytes instances. On a typical machine this saves 3 bytes of memory
1982 (on average) per allocation of a bytes instance.
1983
Christian Heimesa872de52008-12-05 08:26:55 +00001984- Issue #4533: File read operation was dreadfully slow due to a slowly
1985 growing read buffer. Fixed by using the same growth rate algorithm as
1986 Python 2.x.
1987
Antoine Pitrou5504e892008-12-06 21:27:53 +00001988- Issue #4509: Various issues surrounding resize of bytearray objects to
1989 which there are buffer exports (e.g. memoryview instances).
1990
Georg Brandlf9734072008-12-07 15:30:06 +00001991- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1992 method on file objects with closefd=False. The file descriptor is still
1993 kept open but the file object behaves like a closed file. The ``FileIO``
1994 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001995
Antoine Pitroubc420402008-12-07 20:14:49 +00001996- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2004 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2005 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2006 of using the replace error handler in PyUnicode_DecodeUTF8().
