23 described in C99 Annex F.
24
Mark Dickinsoncbb62742009-12-27 15:09:50 +000025- Issue #1811: improve accuracy and cross-platform consistency for
26 true division of integers: the result of a/b is now correctly
27 rounded for ints a and b (at least on IEEE 754 platforms), and in
28 particular does not depend on the internal representation of an int.
29
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000030- Issue #6834: replace the implementation for the 'python' and 'pythonw'
31 executables on OSX.

53
Mark Dickinsond550c9a2009-11-15 09:57:26 +000054- Issue #7298: fixes for range and reversed(range(...)). Iteration
55 over range(a, b, c) incorrectly gave an empty iterator when a, b and
56 c fit in C long but the length of the range did not. Also fix
57 several cases where reversed(range(a, b, c)) gave wrong results, and
58 fix a refleak for reversed(range(a, b, c)) with large arguments.

Benjamin Peterson05159c42009-12-03 03:01:27 +0000186- Issue #2422: When compiled with the ``--with-valgrind`` option, the
187 pymalloc allocator will be automatically disabled when running under
188 Valgrind. This gives improved memory leak detection when running
189 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou941ee882009-11-11 20:59:38 +0000608- Issue #7295: Do not use a hardcoded file name in test_tarfile.
609
Antoine Pitrou557934f2009-11-06 22:41:14 +0000610- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
611 primitives such as Lock, RLock, Condition, Event and Semaphore.
612
Brett Cannoncfed0292009-11-05 01:26:57 +0000613- Issue #7248 (part 2): Use a unique temporary directory for importlib source
614 tests instead of tempfile.tempdir. This prevents the tests from sharing state
615 between concurrent executions on the same system.
616
Brett Cannon0ae45112009-11-05 01:17:22 +0000617- Issue #7248: In importlib.test.source.util a try/finally block did not make
618 sure that some referenced objects actually were created in the block before
619 calling methods on the object.
620
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000621- Issue #7222: Make thread "reaping" more reliable so that reference
622 leak-chasing test runs give sensible results. The previous method of
623 reaping threads could return successfully while some Thread objects were
624 still referenced. This also introduces a new private function:
625 :func:`_thread._count()`.
626
R. David Murray27144602009-10-19 15:26:16 +0000627- Issue #7151: fixed regrtest -j so that output to stderr from a test no
628 longer runs the risk of causing the worker thread to fail.
629
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000630- Issue #7055: test___all__ now greedily detects all modules which have an
631 __all__ attribute, rather than using a hardcoded and incomplete list.
632
R. David Murray0bc11ae2009-10-18 22:18:17 +0000633- Issue #7058: Added save/restore for things like sys.argv and cwd to
634 runtest_inner in regrtest, with warnings if the called test modifies them,

640 the proper exceptions that should be raised for missing or improper code
641 object bytecode.

920 to be like 'g' but with at least one decimal point and with a
921 default precision of 12. Previously, the behavior the same but with
922 a default precision of 6. This more closely matches str(), and
923 reduces surprises when adding alignment flags to the empty
924 presentation type. This also affects the new complex.__format__ in
925 the same way.
926
Martin v. Löwis011e8422009-05-05 04:43:17 +0000927- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
928
R. David Murrayb18500d2009-05-04 22:59:07 +0000929- Issue #5890: in subclasses of 'property' the __doc__ attribute was
930 shadowed by classtype's, even if it was None. property now
931 inserts the __doc__ into the subclass instance __dict__.
932
Antoine Pitrou244651a2009-05-04 18:56:13 +0000933- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000938- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
939 received a new method, detach(). detach() disconnects the underlying stream
940 from the buffer or text IO and returns it.
941
Mark Dickinson33841c32009-05-01 15:37:04 +0000942- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
943 floats with absolute value over 1e50. Also remove length
944 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
945 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000946
Eric Smith741191f2009-05-06 13:08:15 +0000947- Issue #1588: Add complex.__format__. For example,

949
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000950- Issue #5864: Fix empty format code formatting for floats so that it
951 never gives more than the requested number of significant digits.
952
Eric Smith6dc46f52009-04-27 20:39:49 +0000953- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000966- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000967
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000968- Issue #1869 (and many duplicates): make round(x, n) correctly
969 rounded for a float x, by using the decimal <-> binary conversions
970 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
971 consistently agrees with format(x, '.2f').
972
Benjamin Petersonae937c02009-04-18 20:54:08 +0000973- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
974 some builtin types.
975
Eric Smith0923d1d2009-04-16 20:16:10 +0000976- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
977
Eric Smith35e84722009-04-16 20:21:28 +0000978- Issue #5515: str.format() type 'n' combined with commas and leading
979 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000980
981- Implement PEP 378, Format Specifier for Thousands Separator, for
982 floats.
983
Mark Dickinson3370cce2009-04-17 22:40:53 +0000984- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000985 1e11, not 1e12. This avoids printing 13 significant digits in
986 situations where only 12 of them are correct. Example problem
987 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
988 long time.)
989
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000990- Issue #1580: On most platforms, use a 'short' float repr: for a
991 finite float x, repr(x) now outputs a string based on the shortest
992 sequence of decimal digits that rounds to x. Previous behaviour was
993 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000994 Another minor difference is that the new repr switches to
995 exponential notation at 1e16 instead of the previous 1e17; this
996 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000997
998 There's a new sys attribute sys.float_repr_style, which takes
999 the value 'short' to indicate that we're using short float repr,
1000 and 'legacy' if the short float repr isn't available for one
1001 reason or another.
1002
1003 The float repr change involves incorporating David Gay's 'perfect
1004 rounding' code into the Python core (it's in Python/dtoa.c). As a
1005 secondary consequence, all string-to-float and float-to-string
1006 conversions (including all float formatting operations) will be
1007 correctly rounded on these platforms.
1008
1009 See issue 1580 discussions for details of platforms for which
1010 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001012- Issue #5759: float() didn't call __float__ on str subclasses.
1013
Georg Brandlabc38772009-04-12 15:51:51 +00001014- The string.maketrans() function is deprecated; there is a new static method
1015 maketrans() on the bytes and bytearray classes. This removes confusion about
1016 the types string.maketrans() is supposed to work with, and mirrors the
1017 methods available on the str class.

1182
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001183- Issue #4688: Add a heuristic so that tuples and dicts containing only
1184 untrackable objects are not tracked by the garbage collector. This can
1185 reduce the size of collections and therefore the garbage collection overhead
1186 on long-running programs, depending on their particular use of datatypes.

1307 rotating the object pointer by 4 bits to the right.
1308
Mark Dickinson87ec0852009-02-09 17:15:59 +00001309- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1310 it now forces its argument to double before testing for infinity.
1311
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001312- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1320 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001321
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001322- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001323 were suppressing all exceptions. These include list() and bytearray().
1324
Mark Dickinson1124e712009-01-28 21:25:58 +00001325- Issue #4707: round(x, n) now returns an integer if x is an integer.
1326 Previously it returned a float.
1327
Antoine Pitroub52ec782009-01-25 16:34:23 +00001328- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1329 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1330 evaluation loop is compiled with a new dispatch mechanism which gives
1331 speedups of up to 20%, depending on the system, on various benchmarks.
1332
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001333- Issue #4874: Most builtin decoders now reject unicode input.

1339
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001340- Issue #4838: When a module is deallocated, free the memory backing the
1341 optional module state data.
1342
Mark Dickinson8055afd2009-01-17 10:04:45 +00001343- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1344 type to (void *).
1345
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001346- Issue #4935: The overflow checking code in the expandtabs() method common
1347 to str, bytes and bytearray could be optimized away by the compiler, letting
1348 the interpreter segfault instead of raising an error.
1349
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001350- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1351 __next__ method.
1352
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001353- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1354 function no longer attempt to call the __long__ slot to convert an object
1355 to an integer. Only the __int__ and __trunc__ slots are examined.
1356
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001357- Issue #4893: Use NT threading on CE.
1358
Martin v. Löwisec59d042009-01-12 07:59:10 +00001359- Issue #4915: Port sysmodule to Windows CE.
1360
Antoine Pitrouab868312009-01-10 15:40:25 +00001361- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1362 common cases are optimized thanks to a dedicated fast path and a moderate
1363 amount of loop unrolling.
1364
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001365- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1366 collecting the oldest generation) so that allocating lots of objects without
1367 destroying them does not show quadratic performance. Based on a proposal by
1368 Martin von Löwis at
1369 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1370
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001371- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001372 having been closed (for instance, a read() call could return some
1373 previously buffered data). Patch by Dmitry Vasiliev.
1374
Antoine Pitrou05608432009-01-09 18:53:14 +00001375- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1376 flag to work properly. Furthermore, when specifying -u, the text stdout
1377 and stderr streams have line-by-line buffering enabled (the default being
1378 to buffer arbitrary chunks of data).
1379
Raymond Hettinger35631532009-01-09 03:58:09 +00001380- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1381 instead of ints (reducing its size from 4 to 8 times thereby reducing
1382 Python's overall memory).
1383
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001384- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1385 an existing .py counterpart, override the co_filename attributes of all
1386 code objects if the original filename is obsolete (which can happen if the
1387 file has been renamed, moved, or if it is accessed through different paths).
1388 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1389
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001390- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1391 one byte. Also fixes the meaning of len() so that it returns the number of
1392 items, rather than the size in bytes.
1393
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001394- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1395
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001396- Issue #4747: When the terminal does not use utf-8, executing a script with
1397 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1398
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001399- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001400 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001401
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001402- Issue #3680: Reference cycles created through a dict, set or deque iterator
1403 did not get collected.
1404
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001405- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1406 where the tp_hash and tp_dict slots are both NULL.
1407
Georg Brandlccc47b62008-12-28 11:44:14 +00001408- Issue #4759: None is now allowed as the first argument of
1409 bytearray.translate(). It was always allowed for bytes.translate().
1410
Skip Montanaro80072cb2008-12-23 03:51:14 +00001411- Added test case to ensure attempts to read from a file opened for writing
1412 fail.
1413
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001414- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001416- Issue #2183: Simplify and optimize bytecode for list, dict and set
1417 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1418
Antoine Pitrou621601a2008-12-17 23:18:19 +00001419- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1420 print elapsed times, not only when some objects are uncollectable /
1421 unreachable. Original patch by Neil Schemenauer.
1422
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001423- Issue #3439: Add a bit_length method to int.
1424
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001425- Issue #2173: When getting device encoding, check that return value of
1426 nl_langinfo is not the empty string. This was causing silent build
1427 failures on OS X.
1428
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001429- Issue #4597: Fixed several opcodes that weren't always propagating
1430 exceptions.
1431
1432- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001433 context manager returns a value that cannot be converted to a bool.
1434
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001435- Issue #4445: Replace "sizeof(PyBytesObject)" with
1436 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1437 bytes instances. On a typical machine this saves 3 bytes of memory
1438 (on average) per allocation of a bytes instance.
1439
Christian Heimesa872de52008-12-05 08:26:55 +00001440- Issue #4533: File read operation was dreadfully slow due to a slowly
1441 growing read buffer. Fixed by using the same growth rate algorithm as
1442 Python 2.x.
1443
Antoine Pitrou5504e892008-12-06 21:27:53 +00001444- Issue #4509: Various issues surrounding resize of bytearray objects to
1445 which there are buffer exports (e.g. memoryview instances).
1446
Georg Brandlf9734072008-12-07 15:30:06 +00001447- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1448 method on file objects with closefd=False. The file descriptor is still
1449 kept open but the file object behaves like a closed file. The ``FileIO``
1450 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001451
Antoine Pitroubc420402008-12-07 20:14:49 +00001452- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1458
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001459- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1460 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1461 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1462 of using the replace error handler in PyUnicode_DecodeUTF8().
