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.

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'.

1224
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001225- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1226 of the command line.
1227
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001228- Issue #6012: Add cleanup support to O& argument parsing.
1229
Eric Smith41669ca2009-05-23 14:23:22 +00001230- Issue #6089: Fixed str.format with certain invalid field specifiers
1231 that would raise SystemError.
1232
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001233- Issue #5982: staticmethod and classmethod now expose the wrapped
1234 function with __func__.
1235
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001236- Added support for multiple context managers in the same with-statement.
1237 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001238
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001239- Issue #5829: complex("1e500") no longer raises OverflowError. This
1240 makes it consistent with float("1e500") and interpretation of real
1241 and imaginary literals.
1242
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001243- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1244
R. David Murraydd226ea2009-05-13 12:27:21 +00001245- Issue #5994: the marshal module now has docstrings.
1246
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001247- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1248 (1) inf and nan strings with trailing whitespace were incorrectly
1249 rejected; (2) parsing of strings representing infinities and nans
1250 was locale aware; and (3) the interpretation of fromhex('-nan')
1251 didn't match that of float('-nan').

Benjamin Petersonaccdca52009-05-06 23:26:59 +00001253Library
1254-------
1255
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001256- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1257
R. David Murrayfb123912009-05-28 18:19:00 +00001258- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1259
R. David Murray1f1b9d32009-05-27 20:56:59 +00001260- Issue #6121: pydoc now ignores leading and trailing spaces in the
1261 argument to the 'help' function.
1262
Georg Brandlfaf41492009-05-26 18:31:11 +00001263- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1264 arguments for strings with a space in them.
1265
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001266- collections.namedtuple() was not working with the following field
1267 names: cls, self, tuple, itemgetter, and property.
1268
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001269- In unittest, using a skipping decorator on a class is now equivalent to
1270 skipping every test on the class. The ClassTestSuite class has been removed.
1271
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001272- Issue #6050: Don't fail extracting a directory from a zipfile if
1273 the directory already exists.
1274
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001275- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1276 than an int, which makes some operations possible under 64-bit Linux (e.g.
1277 DN_MULTISHOT with F_NOTIFY).
1278
Antoine Pitrou716c4442009-05-23 19:04:03 +00001279- Issue #5761: Add the name of the underlying file to the repr() of various

1283 by Musashi Tamura, tests by Marcin Bachry.
1284
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001285- Issue #1983: Fix functions taking or returning a process identifier to use
1286 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1287 a process identifier type wider than the standard C integer type.
1288
R. David Murray87e20742009-05-23 01:30:26 +00001289- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1293 deepcopy()ing.
1294

1300
Antoine Pitroue4501852009-05-14 18:55:55 +00001301- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1302 library. This means, for example, that opening an UTF-16 text file in
1303 append mode doesn't add a BOM at the end of the file if the file isn't
1304 empty.
1305
R. David Murray74b89242009-05-13 17:33:03 +00001306- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1307 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1308 corrects a pydoc regression.
1309
R. David Murray99352742009-05-07 18:24:38 +00001310- Issue 5955: aifc's close method did not close the file it wrapped,
1311 now it does. This also means getfp method now returns the real fp.
1312
Benjamin Peterson932073a2009-05-23 16:14:33 +00001313Installation
1314------------
1315
1316- Issue #6047: fullinstall has been removed because Python 3's executable will

Brett Cannon1262e7c2009-05-11 01:47:11 +00001340Tests
1341-----
1342
1343- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1344 tests on darwin even when the OS was installed on a case-sensitive
1345 filesystem. Also fixed tests that should not be run when
1346 sys.dont_write_bytecode is true.

1348
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001349What's New in Python 3.1 beta 1?
1350================================
1351
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001352*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001353
1354Core and Builtins
1355-----------------
1356
Mark Dickinson865e01a2009-05-07 16:37:01 +00001357- Issue #5914: Add new C API function PyOS_string_to_double, and
1358 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1359
Eric Smith741191f2009-05-06 13:08:15 +00001360- Issue #3382: float.__format__, complex.__format__, and %-formatting
1361 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1362 affects nan -> NAN and inf -> INF.
1363
Mark Hammond5a607a32009-05-06 08:04:54 +00001364- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1365 in all operations, including splitdrive, split, etc. splitunc() now issues
1366 a PendingDeprecation warning.
1367
Eric Smith63376222009-05-05 14:04:18 +00001368- Issue #5920: For float.__format__, change the behavior with the
1369 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1370 to be like 'g' but with at least one decimal point and with a
1371 default precision of 12. Previously, the behavior the same but with
1372 a default precision of 6. This more closely matches str(), and
1373 reduces surprises when adding alignment flags to the empty
1374 presentation type. This also affects the new complex.__format__ in
1375 the same way.
1376
Martin v. Löwis011e8422009-05-05 04:43:17 +00001377- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1378
R. David Murrayb18500d2009-05-04 22:59:07 +00001379- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1380 shadowed by classtype's, even if it was None. property now
1381 inserts the __doc__ into the subclass instance __dict__.
1382
Antoine Pitrou244651a2009-05-04 18:56:13 +00001383- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1384 sequences. Patch by Nick Barnes and Victor Stinner.
1385
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001386- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001387
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001388- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1389 received a new method, detach(). detach() disconnects the underlying stream
1390 from the buffer or text IO and returns it.
1391
Mark Dickinson33841c32009-05-01 15:37:04 +00001392- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1393 floats with absolute value over 1e50. Also remove length
1394 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1395 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001396
Eric Smith741191f2009-05-06 13:08:15 +00001397- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001398 format(complex(1, 2./3), '.5') now produces a sensible result.
1399
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001400- Issue #5864: Fix empty format code formatting for floats so that it
1401 never gives more than the requested number of significant digits.
1402
Eric Smith6dc46f52009-04-27 20:39:49 +00001403- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1404 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1405
Eric Smithcc32a112009-04-26 21:35:14 +00001406- Issue #5835: Deprecate PyOS_ascii_formatd.
1407
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001408- Issue #4971: Fix titlecase for characters that are their own
1409 titlecase, but not their own uppercase.
1410
Benjamin Peterson193152c2009-04-25 01:08:45 +00001411- Issue #5283: Setting __class__ in __del__ caused a segfault.
1412
Mark Dickinsonad476da2009-04-23 19:14:16 +00001413- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1414 z involves nans, infs or negative zeros.
1415
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001416- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001417
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001418- Issue #1869 (and many duplicates): make round(x, n) correctly
1419 rounded for a float x, by using the decimal <-> binary conversions
1420 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1421 consistently agrees with format(x, '.2f').
1422
Benjamin Petersonae937c02009-04-18 20:54:08 +00001423- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1424 some builtin types.
1425
Eric Smith0923d1d2009-04-16 20:16:10 +00001426- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1427
Eric Smith35e84722009-04-16 20:21:28 +00001428- Issue #5515: str.format() type 'n' combined with commas and leading
1429 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001430
1431- Implement PEP 378, Format Specifier for Thousands Separator, for
1432 floats.
1433
Mark Dickinson3370cce2009-04-17 22:40:53 +00001434- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001435 1e11, not 1e12. This avoids printing 13 significant digits in
1436 situations where only 12 of them are correct. Example problem
1437 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1438 long time.)
1439
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001440- Issue #1580: On most platforms, use a 'short' float repr: for a
1441 finite float x, repr(x) now outputs a string based on the shortest
1442 sequence of decimal digits that rounds to x. Previous behaviour was
1443 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001444 Another minor difference is that the new repr switches to
1445 exponential notation at 1e16 instead of the previous 1e17; this
1446 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001447
1448 There's a new sys attribute sys.float_repr_style, which takes
1449 the value 'short' to indicate that we're using short float repr,
1450 and 'legacy' if the short float repr isn't available for one
1451 reason or another.
1452
1453 The float repr change involves incorporating David Gay's 'perfect
1454 rounding' code into the Python core (it's in Python/dtoa.c). As a
1455 secondary consequence, all string-to-float and float-to-string
1456 conversions (including all float formatting operations) will be
1457 correctly rounded on these platforms.
1458
1459 See issue 1580 discussions for details of platforms for which
1460 this change does not apply.
1461
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001462- Issue #5759: float() didn't call __float__ on str subclasses.
1463
Georg Brandlabc38772009-04-12 15:51:51 +00001464- The string.maketrans() function is deprecated; there is a new static method
1465 maketrans() on the bytes and bytearray classes. This removes confusion about
1466 the types string.maketrans() is supposed to work with, and mirrors the
1467 methods available on the str class.
1468
R. David Murraydc6da8a2009-04-09 22:16:43 +00001469- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsone94c6792009-02-02 20:36:42 +00001769 the type definition cmpfunc. The tp_compare slot has been renamed
1770 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001772- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001773 were suppressing all exceptions. These include list() and bytearray().
1774
Mark Dickinson1124e712009-01-28 21:25:58 +00001775- Issue #4707: round(x, n) now returns an integer if x is an integer.
1776 Previously it returned a float.
1777
Antoine Pitroub52ec782009-01-25 16:34:23 +00001778- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1779 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1780 evaluation loop is compiled with a new dispatch mechanism which gives
1781 speedups of up to 20%, depending on the system, on various benchmarks.
1782
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001783- Issue #4874: Most builtin decoders now reject unicode input.

1789
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001790- Issue #4838: When a module is deallocated, free the memory backing the
1791 optional module state data.
1792
Mark Dickinson8055afd2009-01-17 10:04:45 +00001793- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1794 type to (void *).
1795
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001796- Issue #4935: The overflow checking code in the expandtabs() method common
1797 to str, bytes and bytearray could be optimized away by the compiler, letting
1798 the interpreter segfault instead of raising an error.
1799
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001800- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1801 __next__ method.
1802
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001803- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1804 function no longer attempt to call the __long__ slot to convert an object
1805 to an integer. Only the __int__ and __trunc__ slots are examined.

1810
Antoine Pitrouab868312009-01-10 15:40:25 +00001811- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1812 common cases are optimized thanks to a dedicated fast path and a moderate
1813 amount of loop unrolling.
1814
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001815- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1816 collecting the oldest generation) so that allocating lots of objects without
1817 destroying them does not show quadratic performance. Based on a proposal by
1818 Martin von Löwis at
1819 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1820
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001821- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001822 having been closed (for instance, a read() call could return some
1823 previously buffered data). Patch by Dmitry Vasiliev.
1824
Antoine Pitrou05608432009-01-09 18:53:14 +00001825- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1826 flag to work properly. Furthermore, when specifying -u, the text stdout
1827 and stderr streams have line-by-line buffering enabled (the default being
1828 to buffer arbitrary chunks of data).
1829
Raymond Hettinger35631532009-01-09 03:58:09 +00001830- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1831 instead of ints (reducing its size from 4 to 8 times thereby reducing
1832 Python's overall memory).
1833
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001834- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1835 an existing .py counterpart, override the co_filename attributes of all
1836 code objects if the original filename is obsolete (which can happen if the
1837 file has been renamed, moved, or if it is accessed through different paths).
1838 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1839
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001840- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1841 one byte. Also fixes the meaning of len() so that it returns the number of
1842 items, rather than the size in bytes.
1843
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001844- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1845
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001846- Issue #4747: When the terminal does not use utf-8, executing a script with
1847 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1848
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001849- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1853 did not get collected.
1854
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001855- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1856 where the tp_hash and tp_dict slots are both NULL.
1857
Georg Brandlccc47b62008-12-28 11:44:14 +00001858- Issue #4759: None is now allowed as the first argument of
1859 bytearray.translate(). It was always allowed for bytes.translate().
1860
Skip Montanaro80072cb2008-12-23 03:51:14 +00001861- Added test case to ensure attempts to read from a file opened for writing
1862 fail.
1863
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001864- Issue #3106: Speedup some comparisons (str/str and int/int).

1868
Antoine Pitrou621601a2008-12-17 23:18:19 +00001869- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1871 unreachable. Original patch by Neil Schemenauer.
1872

1874
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001875- Issue #2173: When getting device encoding, check that return value of
1876 nl_langinfo is not the empty string. This was causing silent build
1877 failures on OS X.
1878
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001879- Issue #4597: Fixed several opcodes that weren't always propagating
1880 exceptions.
1881
1882- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001883 context manager returns a value that cannot be converted to a bool.
1884
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001885- Issue #4445: Replace "sizeof(PyBytesObject)" with
1886 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1887 bytes instances. On a typical machine this saves 3 bytes of memory
1888 (on average) per allocation of a bytes instance.
1889
Christian Heimesa872de52008-12-05 08:26:55 +00001890- Issue #4533: File read operation was dreadfully slow due to a slowly
1891 growing read buffer. Fixed by using the same growth rate algorithm as
1892 Python 2.x.
1893
Antoine Pitrou5504e892008-12-06 21:27:53 +00001894- Issue #4509: Various issues surrounding resize of bytearray objects to
1895 which there are buffer exports (e.g. memoryview instances).
1896
Georg Brandlf9734072008-12-07 15:30:06 +00001897- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1898 method on file objects with closefd=False. The file descriptor is still
1899 kept open but the file object behaves like a closed file. The ``FileIO``
1900 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001909- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1910 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1911 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1912 of using the replace error handler in PyUnicode_DecodeUTF8().

2191 do an explicit seek to the end of file (so that e.g. tell() returns the
