825 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
826
Eric Smith741191f2009-05-06 13:08:15 +0000827- Issue #3382: float.__format__, complex.__format__, and %-formatting
828 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
829 affects nan -> NAN and inf -> INF.

Eric Smith63376222009-05-05 14:04:18 +0000835- Issue #5920: For float.__format__, change the behavior with the
836 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
837 to be like 'g' but with at least one decimal point and with a
838 default precision of 12. Previously, the behavior the same but with
839 a default precision of 6. This more closely matches str(), and
840 reduces surprises when adding alignment flags to the empty
841 presentation type. This also affects the new complex.__format__ in
842 the same way.

856 received a new method, detach(). detach() disconnects the underlying stream
857 from the buffer or text IO and returns it.
858
Mark Dickinson33841c32009-05-01 15:37:04 +0000859- Issue #5859: Remove switch from '%f' to '%g'-style formatting for

Mark Dickinsonad476da2009-04-23 19:14:16 +0000880- Issue #5816: complex(repr(z)) now recovers z exactly, even when
881 z involves nans, infs or negative zeros.
882
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000883- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000884
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000885- Issue #1869 (and many duplicates): make round(x, n) correctly
886 rounded for a float x, by using the decimal <-> binary conversions
887 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
888 consistently agrees with format(x, '.2f').
889
Benjamin Petersonae937c02009-04-18 20:54:08 +0000890- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
891 some builtin types.
892
Eric Smith0923d1d2009-04-16 20:16:10 +0000893- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
894
Eric Smith35e84722009-04-16 20:21:28 +0000895- Issue #5515: str.format() type 'n' combined with commas and leading
896 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000897
898- Implement PEP 378, Format Specifier for Thousands Separator, for
899 floats.
900
Mark Dickinson3370cce2009-04-17 22:40:53 +0000901- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000902 1e11, not 1e12. This avoids printing 13 significant digits in
903 situations where only 12 of them are correct. Example problem
904 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
905 long time.)
906
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000907- Issue #1580: On most platforms, use a 'short' float repr: for a
908 finite float x, repr(x) now outputs a string based on the shortest
909 sequence of decimal digits that rounds to x. Previous behaviour was
910 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000911 Another minor difference is that the new repr switches to
912 exponential notation at 1e16 instead of the previous 1e17; this
913 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000914
915 There's a new sys attribute sys.float_repr_style, which takes
916 the value 'short' to indicate that we're using short float repr,
917 and 'legacy' if the short float repr isn't available for one
918 reason or another.
919
920 The float repr change involves incorporating David Gay's 'perfect
921 rounding' code into the Python core (it's in Python/dtoa.c). As a
922 secondary consequence, all string-to-float and float-to-string
923 conversions (including all float formatting operations) will be
924 correctly rounded on these platforms.
925
926 See issue 1580 discussions for details of platforms for which
927 this change does not apply.
928
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000929- Issue #5759: float() didn't call __float__ on str subclasses.
930
Georg Brandlabc38772009-04-12 15:51:51 +0000931- The string.maketrans() function is deprecated; there is a new static method
932 maketrans() on the bytes and bytearray classes. This removes confusion about
933 the types string.maketrans() is supposed to work with, and mirrors the
934 methods available on the str class.
935
R. David Murraydc6da8a2009-04-09 22:16:43 +0000936- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

941
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000942- Issue #3739: The unicode-internal encoder now reports the number of characters

1099
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001100- Issue #4688: Add a heuristic so that tuples and dicts containing only
1101 untrackable objects are not tracked by the garbage collector. This can
1102 reduce the size of collections and therefore the garbage collection overhead
1103 on long-running programs, depending on their particular use of datatypes.

1159 bytes already but the failure was non-obvious.
1160
Jesse Noller7af4ef82009-03-30 16:47:15 +00001161- Issue #5177: Multiprocessing's SocketListener class now uses

1169
Benjamin Peterson59406a92009-03-26 17:10:29 +00001170- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1171 io.BufferedRandom have been deprecated for removal in Python 3.2.
1172
Lars Gustäbel42e00912009-03-22 20:34:29 +00001173- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1174 forever on incomplete input. That caused tarfile.open() to hang when used
1175 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1176 partial bzip2 compressed data.

Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00001184- The error detection code in FileIO.close() could fail to reflect the `errno`
1185 value, and report it as -1 instead.
1186
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00001187- Issue #5016: FileIO.seekable() could return False if the file position

1196 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001197 struct.error instead of returning b'\xff\xff\xff\xff'. The
1198 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1199 have been removed from the struct module.

1215 used when using str.format() with str, int, and float arguments.
1216
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00001217- Issue #5249: time.strftime returned malformed string when format string
1218 contained non ascii character on windows.
1219
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001220- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1221 source has already been decoded into str.
1222
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001223- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1224 rotating the object pointer by 4 bits to the right.
1225
Mark Dickinson87ec0852009-02-09 17:15:59 +00001226- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1227 it now forces its argument to double before testing for infinity.
1228
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001229- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1230 returns a non-number type.
1231
Benjamin Peterson87618552009-02-08 15:00:52 +00001232- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001238
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001239- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001240 were suppressing all exceptions. These include list() and bytearray().
1241
Mark Dickinson1124e712009-01-28 21:25:58 +00001242- Issue #4707: round(x, n) now returns an integer if x is an integer.
1243 Previously it returned a float.
1244
Antoine Pitroub52ec782009-01-25 16:34:23 +00001245- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1246 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1247 evaluation loop is compiled with a new dispatch mechanism which gives
1248 speedups of up to 20%, depending on the system, on various benchmarks.
1249
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001250- Issue #4874: Most builtin decoders now reject unicode input.

1256
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001257- Issue #4838: When a module is deallocated, free the memory backing the
1258 optional module state data.
1259
Mark Dickinson8055afd2009-01-17 10:04:45 +00001260- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1261 type to (void *).
1262
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001263- Issue #4935: The overflow checking code in the expandtabs() method common
1264 to str, bytes and bytearray could be optimized away by the compiler, letting
1265 the interpreter segfault instead of raising an error.
1266
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001267- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1268 __next__ method.
1269
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001270- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1271 function no longer attempt to call the __long__ slot to convert an object
1272 to an integer. Only the __int__ and __trunc__ slots are examined.
1273
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001274- Issue #4893: Use NT threading on CE.
1275
Martin v. Löwisec59d042009-01-12 07:59:10 +00001276- Issue #4915: Port sysmodule to Windows CE.
1277
Antoine Pitrouab868312009-01-10 15:40:25 +00001278- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1279 common cases are optimized thanks to a dedicated fast path and a moderate
1280 amount of loop unrolling.
1281
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001282- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1283 collecting the oldest generation) so that allocating lots of objects without
1284 destroying them does not show quadratic performance. Based on a proposal by
1285 Martin von Löwis at
1286 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1287
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001288- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001289 having been closed (for instance, a read() call could return some
1290 previously buffered data). Patch by Dmitry Vasiliev.
1291
Antoine Pitrou05608432009-01-09 18:53:14 +00001292- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1293 flag to work properly. Furthermore, when specifying -u, the text stdout
1294 and stderr streams have line-by-line buffering enabled (the default being
1295 to buffer arbitrary chunks of data).
1296
Raymond Hettinger35631532009-01-09 03:58:09 +00001297- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1298 instead of ints (reducing its size from 4 to 8 times thereby reducing
1299 Python's overall memory).
1300
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001301- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1302 an existing .py counterpart, override the co_filename attributes of all
1303 code objects if the original filename is obsolete (which can happen if the
1304 file has been renamed, moved, or if it is accessed through different paths).
1305 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1306
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001307- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1308 one byte. Also fixes the meaning of len() so that it returns the number of
1309 items, rather than the size in bytes.
1310
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001311- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1312
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001313- Issue #4747: When the terminal does not use utf-8, executing a script with
1314 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1315
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001316- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001317 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001318
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001319- Issue #3680: Reference cycles created through a dict, set or deque iterator
1320 did not get collected.
1321
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001322- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1323 where the tp_hash and tp_dict slots are both NULL.
1324
Georg Brandlccc47b62008-12-28 11:44:14 +00001325- Issue #4759: None is now allowed as the first argument of
1326 bytearray.translate(). It was always allowed for bytes.translate().
1327
Skip Montanaro80072cb2008-12-23 03:51:14 +00001328- Added test case to ensure attempts to read from a file opened for writing
1329 fail.
1330
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001331- Issue #3106: Speedup some comparisons (str/str and int/int).
1332
Antoine Pitrouf289ae62008-12-18 11:06:25 +00001333- Issue #2183: Simplify and optimize bytecode for list, dict and set
1334 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1335
Antoine Pitrou621601a2008-12-17 23:18:19 +00001336- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1337 print elapsed times, not only when some objects are uncollectable /
1338 unreachable. Original patch by Neil Schemenauer.
1339
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001340- Issue #3439: Add a bit_length method to int.
1341
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001342- Issue #2173: When getting device encoding, check that return value of
1343 nl_langinfo is not the empty string. This was causing silent build
1344 failures on OS X.
1345
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001346- Issue #4597: Fixed several opcodes that weren't always propagating
1347 exceptions.
1348
1349- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001350 context manager returns a value that cannot be converted to a bool.
1351
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001352- Issue #4445: Replace "sizeof(PyBytesObject)" with
1353 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1354 bytes instances. On a typical machine this saves 3 bytes of memory
1355 (on average) per allocation of a bytes instance.
1356
Christian Heimesa872de52008-12-05 08:26:55 +00001357- Issue #4533: File read operation was dreadfully slow due to a slowly
1358 growing read buffer. Fixed by using the same growth rate algorithm as
1359 Python 2.x.
1360
Antoine Pitrou5504e892008-12-06 21:27:53 +00001361- Issue #4509: Various issues surrounding resize of bytearray objects to
1362 which there are buffer exports (e.g. memoryview instances).
1363
Georg Brandlf9734072008-12-07 15:30:06 +00001364- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1365 method on file objects with closefd=False. The file descriptor is still
1366 kept open but the file object behaves like a closed file. The ``FileIO``
1367 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001368
Antoine Pitroubc420402008-12-07 20:14:49 +00001369- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1370 larger than 1.
1371

1375
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001376- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1377 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1378 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1379 of using the replace error handler in PyUnicode_DecodeUTF8().
