746 that for incoming headers which makes this behaviour now consistent in
747 both incoming and outgoing direction.

Éric Araujof0ab5d62011-05-29 03:43:59 +0200863- email.header.Header was incorrectly encoding folding whitespace when

865 folding whitespace. It now uses the continuation_ws, as it does for
866 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +0000868- Issue #1777412, #10827: Changed the rules for 2-digit years. The
869 time.asctime(), time.ctime() and time.strftime() functions will now format
870 any year when ``time.accept2dyear`` is False and will accept years >= 1000
871 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
872 supported by the OS. With Visual Studio or on Solaris, the year is limited to
873 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001502- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1503 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001504 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001505 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001506 encoding and to encode command line arguments on this OS.

1509 filenames encoded to the filesystem encoding with the surrogateescape error

1511
Benjamin Peterson230b2062010-10-16 03:45:45 +00001512- Issue #9997: Don't let the name "top" have special significance in scope

1873
Brett Cannon5305a992010-09-27 21:08:38 +00001874- Issue #7397: Mention that importlib.import_module() is probably what someone
1875 really wants to be using in __import__'s docstring.
1876
Georg Brandl27a28582010-10-10 09:49:21 +00001877- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1878 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001880- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001881 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00001883- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1884
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001885- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1886 threads are still running. Instead, reinitialize the GIL on a second call to
1887 Py_Initialize().
1888
Georg Brandl27a28582010-10-10 09:49:21 +00001889- All SyntaxErrors now have a column offset and therefore a caret when the error
1890 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001891
Brett Cannonbc2eff32010-09-19 21:39:02 +00001892- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1893 module that was imported, but instead gets the module from sys.modules.
1894
Nick Coghlan37ee8502010-12-03 14:26:13 +00001895- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001896 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001897
Georg Brandl27a28582010-10-10 09:49:21 +00001898- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1899 with a non-empty format string. This is an effort to future-proof user
1900 code. If a derived class does not currently implement __format__ but later
1901 adds its own __format__, it would most likely break user code that had
1902 supplied a format string. This will be changed to a DeprecationWaring in
1903 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001904
Antoine Pitrou1df15362010-09-13 14:16:46 +00001905- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1906 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1907 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1908
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001909- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1910 functions from the libc caused the methods .upper() and lower() to become
1911 locale aware and created subtly wrong results.
1912
Georg Brandl27a28582010-10-10 09:49:21 +00001913- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1914 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001915
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001916- Issue #4617: Previously it was illegal to delete a name from the local
1917 namespace if it occurs as a free variable in a nested block. This limitation
1918 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1919
Georg Brandl27a28582010-10-10 09:49:21 +00001920- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1921 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1922 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1923 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001925- Issue #9757: memoryview objects get a release() method to release the
1926 underlying buffer (previously this was only done when deallocating the
1927 memoryview), and gain support for the context management protocol.
1928
Antoine Pitrou079ce542010-09-08 12:37:10 +00001929- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1930 thread-local storage key.

1957
Éric Araujoef777bd2010-10-05 00:04:20 +00001958- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001959 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001960 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001961 replacement for old handle_accept() and avoids the user to call accept()
1962 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001985- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001986 retry the select() loop instead of bailing out. This is because select() can
1987 incorrectly report a socket as ready for reading (for example, if it received
1988 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002035 non-blocking mode: they return None when an operation would block (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002048- Issue #1552: socket.socketpair() now returns regular socket.socket objects

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002068- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002069 it possible for the user to create self-referencing ordered dictionaries which
2070 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002071 approach of using weakref proxies so that reference cycles never get created
2072 in the first place.

2080 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Georg Brandl27a28582010-10-10 09:49:21 +00002087- The pprint module now supports printing OrderedDicts in their given order

2092
Georg Brandl27a28582010-10-10 09:49:21 +00002093- Issue #9707: Rewritten reference implementation of threading.local which is
2094 friendlier towards reference cycles. This change is not normally visible
2095 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002097- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2098 still return the id of the parent process after it has exited. This process
2099 id may even have been reused by another unrelated process.
2100
Georg Brandl27a28582010-10-10 09:49:21 +00002101- Issue #9792: In case of connection failure, socket.create_connection() would

Georg Brandl27a28582010-10-10 09:49:21 +00002115 * Update the seed() method to use all of the bits in a string instead of just
2116 the hash value. This makes better use of the seed value and assures the

2274 return characters from the full Unicode range, even on narrow unicode builds
2275 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2276 in Python is that unicodedata.numeric() now returns the correct value for
2277 large code points, and repr() may consider more characters as printable.

2315 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002316
2317 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Georg Brandl62069d32010-07-31 08:56:11 +00002658 start byte and the continuation byte(s) are now considered invalid, instead of
2659 the number of bytes specified by the start byte. E.g.:
2660 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2661 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2662 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2663 returned a single u'\ufffd'.

2692
Georg Brandl62069d32010-07-31 08:56:11 +00002693- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002694 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2695 location of the raised exception.
2696
Victor Stinner313a1202010-06-11 23:56:51 +00002697- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode

Georg Brandl62069d32010-07-31 08:56:11 +00002706- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2707 TypeError instead of giving a DeprecationWarning when a float is parsed using
2708 the 'L' code (for long long). (All other integer codes already raise
2709 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002710
Victor Stinner600d3be2010-06-10 12:00:55 +00002711- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2712 enable shortcuts for upper case encoding name. Add also a shortcut for
2713 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2714
Georg Brandl62069d32010-07-31 08:56:11 +00002715- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2716 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002717
2718- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002719 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002720 like bytearray.
2721
Georg Brandl62069d32010-07-31 08:56:11 +00002722- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002723 used anymore and it was never documented.
2724
Georg Brandl62069d32010-07-31 08:56:11 +00002725- In str.format(), raise a ValueError when indexes to arguments are too large.

Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002729
Georg Brandl62069d32010-07-31 08:56:11 +00002730- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2731 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2732 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2733 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002734
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002735- Issue #8748: Fix two issues with comparisons between complex and integer
2736 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002737 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2738 (2) The comparison raised an OverflowError for large integers, leading to
2739 unpredictable exceptions when combining integers and complex objects in sets
2740 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002741
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002742- Issue #8766: Initialize _warnings module before importing the first module.

2744
Victor Stinner9ca9c252010-05-19 16:53:30 +00002745- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002746 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002747 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002748
Georg Brandl62069d32010-07-31 08:56:11 +00002749- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2750 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002751
Victor Stinnerae6265f2010-05-15 16:27:27 +00002752- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2753 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002754 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002755 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002756
Victor Stinner59e62db2010-05-15 13:14:32 +00002757- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002758 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002759
Victor Stinnerb744ba12010-05-15 12:27:16 +00002760- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002761 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002762 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2763
Victor Stinner0964ee12010-04-30 16:48:45 +00002764- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002765 PyUnicode_FromString() to support surrogates in the filename and use the right
2766 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00002768- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2769
Georg Brandl62069d32010-07-31 08:56:11 +00002770- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.

Mark Dickinsone6fc7402010-08-06 18:55:26 +00003046- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3047 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

Georg Brandl62069d32010-07-31 08:56:11 +00003179 applications that use a lot of regular expressions and limits the impact of
3180 the performance hit anytime the cache is exceeded.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00003578- Add functools.total_ordering() and functools.cmp_to_key().
3579
Georg Brandl62069d32010-07-31 08:56:11 +00003580- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandl62069d32010-07-31 08:56:11 +00003589- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3590 InvalidOperation instead of returning False. (Comparisons involving a quiet
3591 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3592 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003593
Georg Brandl62069d32010-07-31 08:56:11 +00003594- Issue #2531: Comparison operations between floats and Decimal instances now
3595 return a result based on the numeric values of the operands; previously they
3596 returned an arbitrary result based on the relative ordering of id(float) and
3597 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3598 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003599
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003600- Added a subtract() method to collections.Counter().
3601
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003602- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003603 argument `-` which tells it to read files to compile from stdin. Each line is
3604 read on demand and the named file is compiled immediately. (Original patch by
3605 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00003607- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00003611- Comparisons using one of <, <=, >, >= between a complex instance and a
3612 Fractions instance now raise TypeError instead of returning True/False. This
3613 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3614 <=> complex, and complex <=> complex comparisons.

3622
Antoine Pitrou910bd512010-03-22 20:11:09 +00003623- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00003624 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00003657- The internals of the subprocess module on POSIX systems have been replaced by
3658 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3659 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003660
Georg Brandl62069d32010-07-31 08:56:11 +00003661- subprocess.Popen now has restore_signals and start_new_session features. The
3662 default of restore_signals=True is a new behavior compared to earlier Python
3663 versions. This means that signals such as SIGPIPE are not ignored by default
3664 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00003750- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
3751 position when calling `truncate()`. It would previously change the file
3752 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003753 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00003755- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00003756 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
3757 archive. The new implementation is significantly faster and can be wrapped in
3758 a :class:`io.BufferedReader` object for more speedups. It also solves an
3759 issue where interleaved calls to `read()` and `readline()` give wrong results.
3760 Patch by Nir Aides.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004157- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004158 compared to other unix systems. In particular, os.getgroups() does not reflect

4161 groups on MacOSX.

4517 threads could return successfully while some Thread objects were still
4518 referenced. This also introduces a new private function:

Georg Brandl62069d32010-07-31 08:56:11 +00004528 runtest_inner in regrtest, with warnings if the called test modifies them, and

4720
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00004721- In unittest, using a skipping decorator on a class is now equivalent to
4722 skipping every test on the class. The ClassTestSuite class has been removed.
4723
Martin v. Löwis70ccd162009-05-24 19:47:22 +00004724- Issue #6050: Don't fail extracting a directory from a zipfile if
4725 the directory already exists.
4726
Antoine Pitrou61f77b52009-05-24 15:46:13 +00004727- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4728 than an int, which makes some operations possible under 64-bit Linux (e.g.
4729 DN_MULTISHOT with F_NOTIFY).
4730
Antoine Pitrou716c4442009-05-23 19:04:03 +00004731- Issue #5761: Add the name of the underlying file to the repr() of various

R. David Murraycaa27b72009-05-23 18:49:56 +00004734- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
4735 by Musashi Tamura, tests by Marcin Bachry.
4736
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00004737- Issue #1983: Fix functions taking or returning a process identifier to use
4738 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
4739 a process identifier type wider than the standard C integer type.
4740

4752
Antoine Pitroue4501852009-05-14 18:55:55 +00004753- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4754 library. This means, for example, that opening an UTF-16 text file in
4755 append mode doesn't add a BOM at the end of the file if the file isn't
4756 empty.
4757
R. David Murray74b89242009-05-13 17:33:03 +00004758- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
4759 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
4760 corrects a pydoc regression.
4761
Georg Brandl5f90d792010-08-01 22:31:05 +00004762- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00004763 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00004805
4806Core and Builtins
4807-----------------
4808
Mark Dickinson865e01a2009-05-07 16:37:01 +00004809- Issue #5914: Add new C API function PyOS_string_to_double, and
4810 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4811
Eric Smith741191f2009-05-06 13:08:15 +00004812- Issue #3382: float.__format__, complex.__format__, and %-formatting
4813 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4814 affects nan -> NAN and inf -> INF.
4815
Mark Hammond5a607a32009-05-06 08:04:54 +00004816- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4817 in all operations, including splitdrive, split, etc. splitunc() now issues
4818 a PendingDeprecation warning.
4819
Eric Smith63376222009-05-05 14:04:18 +00004820- Issue #5920: For float.__format__, change the behavior with the
4821 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4822 to be like 'g' but with at least one decimal point and with a
4823 default precision of 12. Previously, the behavior the same but with
4824 a default precision of 6. This more closely matches str(), and
4825 reduces surprises when adding alignment flags to the empty
4826 presentation type. This also affects the new complex.__format__ in
4827 the same way.
4828
Martin v. Löwis011e8422009-05-05 04:43:17 +00004829- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4830
R. David Murrayb18500d2009-05-04 22:59:07 +00004831- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4832 shadowed by classtype's, even if it was None. property now
4833 inserts the __doc__ into the subclass instance __dict__.
4834
Antoine Pitrou244651a2009-05-04 18:56:13 +00004835- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4836 sequences. Patch by Nick Barnes and Victor Stinner.
4837
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004838- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004839
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004840- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4841 received a new method, detach(). detach() disconnects the underlying stream
4842 from the buffer or text IO and returns it.
4843
Mark Dickinson33841c32009-05-01 15:37:04 +00004844- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4845 floats with absolute value over 1e50. Also remove length
4846 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4847 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004848
Eric Smith741191f2009-05-06 13:08:15 +00004849- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004850 format(complex(1, 2./3), '.5') now produces a sensible result.
4851
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004852- Issue #5864: Fix empty format code formatting for floats so that it
4853 never gives more than the requested number of significant digits.
4854
Eric Smith6dc46f52009-04-27 20:39:49 +00004855- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4856 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4857
Eric Smithcc32a112009-04-26 21:35:14 +00004858- Issue #5835: Deprecate PyOS_ascii_formatd.
4859
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004860- Issue #4971: Fix titlecase for characters that are their own
4861 titlecase, but not their own uppercase.
4862
Benjamin Peterson193152c2009-04-25 01:08:45 +00004863- Issue #5283: Setting __class__ in __del__ caused a segfault.
4864
Mark Dickinsonad476da2009-04-23 19:14:16 +00004865- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4866 z involves nans, infs or negative zeros.
4867
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004868- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004869
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004870- Issue #1869 (and many duplicates): make round(x, n) correctly
4871 rounded for a float x, by using the decimal <-> binary conversions
4872 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4873 consistently agrees with format(x, '.2f').
4874
Benjamin Petersonae937c02009-04-18 20:54:08 +00004875- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4876 some builtin types.
4877
Eric Smith0923d1d2009-04-16 20:16:10 +00004878- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4879
Eric Smith35e84722009-04-16 20:21:28 +00004880- Issue #5515: str.format() type 'n' combined with commas and leading
4881 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004882
4883- Implement PEP 378, Format Specifier for Thousands Separator, for
4884 floats.
4885
Mark Dickinson3370cce2009-04-17 22:40:53 +00004886- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004887 1e11, not 1e12. This avoids printing 13 significant digits in
4888 situations where only 12 of them are correct. Example problem
4889 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4890 long time.)
4891
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004892- Issue #1580: On most platforms, use a 'short' float repr: for a
4893 finite float x, repr(x) now outputs a string based on the shortest
4894 sequence of decimal digits that rounds to x. Previous behaviour was
4895 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004896 Another minor difference is that the new repr switches to
4897 exponential notation at 1e16 instead of the previous 1e17; this
4898 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004899
4900 There's a new sys attribute sys.float_repr_style, which takes
4901 the value 'short' to indicate that we're using short float repr,
4902 and 'legacy' if the short float repr isn't available for one
4903 reason or another.
4904
4905 The float repr change involves incorporating David Gay's 'perfect
4906 rounding' code into the Python core (it's in Python/dtoa.c). As a
4907 secondary consequence, all string-to-float and float-to-string
4908 conversions (including all float formatting operations) will be
4909 correctly rounded on these platforms.
4910
Georg Brandl5f90d792010-08-01 22:31:05 +00004911 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004912 this change does not apply.
4913
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004914- Issue #5759: float() didn't call __float__ on str subclasses.
4915
Georg Brandlabc38772009-04-12 15:51:51 +00004916- The string.maketrans() function is deprecated; there is a new static method
4917 maketrans() on the bytes and bytearray classes. This removes confusion about
4918 the types string.maketrans() is supposed to work with, and mirrors the
4919 methods available on the str class.
4920
R. David Murraydc6da8a2009-04-09 22:16:43 +00004921- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4922 its clarity and its speed.
4923
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004924- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004925 to avoid compiler warnings.
4926
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004927- Issue #3739: The unicode-internal encoder now reports the number of characters
4928 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00005008- Issue #1161031: fix readwrite select flag handling: POLLPRI now
5009 results in a handle_expt_event call, not handle_read_event, and POLLERR
5010 and POLLNVAL now call handle_close, not handle_expt_event. Also,
5011 dispatcher now has an 'ignore_log_types' attribute for suppressing
5012 log messages, which is set to 'warning' by default.
5013
Matthias Klosea3d29e82009-04-07 13:13:10 +00005014- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

5086
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005087- Issue #4688: Add a heuristic so that tuples and dicts containing only
5088 untrackable objects are not tracked by the garbage collector. This can
5089 reduce the size of collections and therefore the garbage collection overhead
5090 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +00005160- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5161 forever on incomplete input. That caused tarfile.open() to hang when used
5162 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5163 partial bzip2 compressed data.
5164
Mark Dickinson79f52032009-03-17 23:12:51 +00005165- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou8043cf82009-01-09 19:54:29 +00005276 having been closed (for instance, a read() call could return some
5277 previously buffered data). Patch by Dmitry Vasiliev.
5278
Antoine Pitrou05608432009-01-09 18:53:14 +00005279- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5280 flag to work properly. Furthermore, when specifying -u, the text stdout

5282 to buffer arbitrary chunks of data).
5283
Raymond Hettinger35631532009-01-09 03:58:09 +00005284- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

Antoine Pitroud35cbf62009-01-06 19:02:24 +00005288- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5289 an existing .py counterpart, override the co_filename attributes of all
5290 code objects if the original filename is obsolete (which can happen if the
5291 file has been renamed, moved, or if it is accessed through different paths).

5340 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

5352 method on file objects with closefd=False. The file descriptor is still
5353 kept open but the file object behaves like a closed file. The ``FileIO``
5354 object also got a new readonly attribute ``closefd``.

5364 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5365 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5366 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00005686- Issue #5008: When a file is opened in append mode with the new IO library,
5687 do an explicit seek to the end of file (so that e.g. tell() returns the

5719 appropriately when it is being used via socket.makefile() objects
5720 rather than delaying the close by waiting for garbage collection to do it.
