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

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001472- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1473 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001474 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001475 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001476 encoding and to encode command line arguments on this OS.

Nick Coghlan37ee8502010-12-03 14:26:13 +00001865- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001866 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00001868- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1869 with a non-empty format string. This is an effort to future-proof user
1870 code. If a derived class does not currently implement __format__ but later
1871 adds its own __format__, it would most likely break user code that had
1872 supplied a format string. This will be changed to a DeprecationWaring in
1873 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00001875- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1876 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1877 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001879- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1880 functions from the libc caused the methods .upper() and lower() to become
1881 locale aware and created subtly wrong results.
1882
Georg Brandl27a28582010-10-10 09:49:21 +00001883- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1884 non-ASCII byte in the format string.

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001886- Issue #4617: Previously it was illegal to delete a name from the local
1887 namespace if it occurs as a free variable in a nested block. This limitation
1888 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1889
Georg Brandl27a28582010-10-10 09:49:21 +00001890- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1891 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1892 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1893 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001895- Issue #9757: memoryview objects get a release() method to release the
1896 underlying buffer (previously this was only done when deallocating the
1897 memoryview), and gain support for the context management protocol.
1898
Antoine Pitrou079ce542010-09-08 12:37:10 +00001899- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00001928- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001929 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001930 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001931 replacement for old handle_accept() and avoids the user to call accept()

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001955- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001956 retry the select() loop instead of bailing out. This is because select() can
1957 incorrectly report a socket as ready for reading (for example, if it received
1958 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002005 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002038- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002039 it possible for the user to create self-referencing ordered dictionaries which
2040 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002041 approach of using weakref proxies so that reference cycles never get created
2042 in the first place.
2043
Victor Stinnercb043522010-09-10 23:49:04 +00002044- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2045 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002046 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002047
Georg Brandl27a28582010-10-10 09:49:21 +00002048- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2049 environment variable to set the filesystem encoding at Python startup.
2050 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2051 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002053- Issue #9410: Various optimizations to the pickle module, leading to speedups

2055 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002056
Georg Brandl27a28582010-10-10 09:49:21 +00002057- The pprint module now supports printing OrderedDicts in their given order

Vinay Sajip121a1c42010-09-08 10:46:15 +00002060- Logging: Added QueueHandler class to facilitate logging usage with
2061 multiprocessing.
2062
Georg Brandl27a28582010-10-10 09:49:21 +00002063- Issue #9707: Rewritten reference implementation of threading.local which is
2064 friendlier towards reference cycles. This change is not normally visible
2065 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002066
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002067- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2068 still return the id of the parent process after it has exited. This process
2069 id may even have been reused by another unrelated process.
2070
Georg Brandl27a28582010-10-10 09:49:21 +00002071- Issue #9792: In case of connection failure, socket.create_connection() would
2072 swallow the exception and raise a new one, making it impossible to fetch the
2073 original errno, or to filter timeout errors. Now the original error is
2074 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002076- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2077 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2078 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002080- Updates to the random module:
2081
Georg Brandl27a28582010-10-10 09:49:21 +00002082 * Document which parts of the module are guaranteed to stay the same across
2083 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002084
Georg Brandl27a28582010-10-10 09:49:21 +00002085 * Update the seed() method to use all of the bits in a string instead of just
2086 the hash value. This makes better use of the seed value and assures the
2087 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002088
Georg Brandl27a28582010-10-10 09:49:21 +00002089 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2090 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2091 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002092
2093 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002098- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
2099 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2100 given warning type was triggered by the code under test.

2244 return characters from the full Unicode range, even on narrow unicode builds
2245 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Georg Brandl649971e2010-09-05 17:06:50 +00002284- Issue #9416: Fix some issues with complex formatting where the output with no
2285 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002286
2287 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

2626
Ezio Melotti57221d02010-07-01 07:32:02 +00002627- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002628 start byte and the continuation byte(s) are now considered invalid, instead of
2629 the number of bytes specified by the start byte. E.g.:
2630 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2631 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2632 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2633 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00002635- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
2636 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

Georg Brandl62069d32010-07-31 08:56:11 +00002647- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
2648 dealing with unary minus applied to a constant. The removed code was mutating
2649 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00002650
Victor Stinner554f3f02010-06-16 23:33:54 +00002651- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00002652 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00002653 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002654 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002655
Victor Stinner25e8ec42010-06-25 00:02:38 +00002656- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
2657 "w*" format instead. Add tests for "w*" format.
2658
Victor Stinner06e49dd2010-06-13 18:21:50 +00002659- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00002660 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00002661 string formats.
2662
Georg Brandl62069d32010-07-31 08:56:11 +00002663- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002664 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2665 location of the raised exception.
2666
Victor Stinner313a1202010-06-11 23:56:51 +00002667- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2668 filenames and enable os.fsencode().
2669
Benjamin Peterson285a6892010-06-22 19:21:52 +00002670- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2671
Georg Brandl62069d32010-07-31 08:56:11 +00002672- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2673 interpreter with characters outside the Basic Multilingual Plane (higher than
2674 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00002675
Georg Brandl62069d32010-07-31 08:56:11 +00002676- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2677 TypeError instead of giving a DeprecationWarning when a float is parsed using
2678 the 'L' code (for long long). (All other integer codes already raise
2679 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002680
Victor Stinner600d3be2010-06-10 12:00:55 +00002681- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2682 enable shortcuts for upper case encoding name. Add also a shortcut for
2683 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2684
Georg Brandl62069d32010-07-31 08:56:11 +00002685- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2686 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002687
2688- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002689 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002690 like bytearray.
2691
Georg Brandl62069d32010-07-31 08:56:11 +00002692- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002693 used anymore and it was never documented.
2694
Georg Brandl62069d32010-07-31 08:56:11 +00002695- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00002696
Georg Brandl62069d32010-07-31 08:56:11 +00002697- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2698 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002699
Georg Brandl62069d32010-07-31 08:56:11 +00002700- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
2701 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
2702 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
2703 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00002704
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002705- Issue #8748: Fix two issues with comparisons between complex and integer
2706 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002707 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2708 (2) The comparison raised an OverflowError for large integers, leading to
2709 unpredictable exceptions when combining integers and complex objects in sets
2710 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002711
Victor Stinner7d79b8b2010-05-19 20:40:50 +00002712- Issue #8766: Initialize _warnings module before importing the first module.
2713 Fix a crash if an empty directory called "encodings" exists in sys.path.
2714
Victor Stinner9ca9c252010-05-19 16:53:30 +00002715- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00002716 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00002717 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00002718
Georg Brandl62069d32010-07-31 08:56:11 +00002719- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
2720 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00002721
Victor Stinnerae6265f2010-05-15 16:27:27 +00002722- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
2723 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00002724 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00002725 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00002726
Victor Stinner59e62db2010-05-15 13:14:32 +00002727- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00002728 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00002729
Victor Stinnerb744ba12010-05-15 12:27:16 +00002730- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00002731 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00002732 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
2733
Victor Stinner0964ee12010-04-30 16:48:45 +00002734- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00002735 PyUnicode_FromString() to support surrogates in the filename and use the right
2736 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00002737
Georg Brandl8569e582010-05-19 20:57:08 +00002738- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
2739
Georg Brandl62069d32010-07-31 08:56:11 +00002740- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00002741
Benjamin Petersonfb886362010-04-24 18:21:17 +00002742- Issue #8419: Prevent the dict constructor from accepting non-string keyword
2743 arguments.
2744
Victor Stinner14284c22010-04-23 12:02:30 +00002745- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00002746 indirectly Python signal handlers anymore because mywrite() ignores exceptions
2747 (KeyboardInterrupt).

Georg Brandl62069d32010-07-31 08:56:11 +00002752- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
2753 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00002754
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00002755- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00002756 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit

2836 crash in many places because of the PyByteArray_AS_STRING() macro returning
2837 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00002839- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00002840 where the right hand operand is a set of constants, by turning the set into a
2841 frozenset and pre-building it as a constant. The comparison operation is made
2842 against the constant instead of building a new set each time it is executed (a
2843 similar optimization already existed which turned a list of constants into a
2844 pre-built tuple). Patch and additional tests by Dave Malcolm.

2870 of integers: the result of a/b is now correctly rounded for ints a and b (at
2871 least on IEEE 754 platforms), and in particular does not depend on the
2872 internal representation of an int.

Antoine Pitrou3060c452010-08-13 16:27:38 +00003147 simply clearing the entire cache on overflow to forgetting the least recently
3148 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003149 applications that use a lot of regular expressions and limits the impact of
3150 the performance hit anytime the cache is exceeded.

3272 operands. This builds on issue #2531, which allowed Decimal-to-float
3273 comparisons; all comparisons involving numeric types (bool, int, float,
3274 complex, Decimal, Fraction) should now act as expected.

Georg Brandl62069d32010-07-31 08:56:11 +00003559- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3560 InvalidOperation instead of returning False. (Comparisons involving a quiet
3561 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3562 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003564- Issue #2531: Comparison operations between floats and Decimal instances now
3565 return a result based on the numeric values of the operands; previously they
3566 returned an arbitrary result based on the relative ordering of id(float) and
3567 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3568 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003569
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003570- Added a subtract() method to collections.Counter().
3571
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003572- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003573 argument `-` which tells it to read files to compile from stdin. Each line is
3574 read on demand and the named file is compiled immediately. (Original patch by
3575 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00003581- Comparisons using one of <, <=, >, >= between a complex instance and a
3582 Fractions instance now raise TypeError instead of returning True/False. This
3583 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3584 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003627- The internals of the subprocess module on POSIX systems have been replaced by
3628 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3629 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003630
Georg Brandl62069d32010-07-31 08:56:11 +00003631- subprocess.Popen now has restore_signals and start_new_session features. The
3632 default of restore_signals=True is a new behavior compared to earlier Python
3633 versions. This means that signals such as SIGPIPE are not ignored by default
3634 in subprocesses launched by Python (Issue #1652).

3721 position when calling `truncate()`. It would previously change the file
3722 position to the given argument, which goes against the tradition of

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004127- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004128 compared to other unix systems. In particular, os.getgroups() does not reflect
4129 any changes made using os.setgroups() but basicly always returns the same
4130 information as the id command. os.getgroups() can now return more than 16
4131 groups on MacOSX.

Antoine Pitroue4501852009-05-14 18:55:55 +00004723- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4724 library. This means, for example, that opening an UTF-16 text file in
4725 append mode doesn't add a BOM at the end of the file if the file isn't

4776Core and Builtins
4777-----------------
4778
Mark Dickinson865e01a2009-05-07 16:37:01 +00004779- Issue #5914: Add new C API function PyOS_string_to_double, and
4780 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4781
Eric Smith741191f2009-05-06 13:08:15 +00004782- Issue #3382: float.__format__, complex.__format__, and %-formatting
4783 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4784 affects nan -> NAN and inf -> INF.
4785
Mark Hammond5a607a32009-05-06 08:04:54 +00004786- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4787 in all operations, including splitdrive, split, etc. splitunc() now issues
4788 a PendingDeprecation warning.
4789
Eric Smith63376222009-05-05 14:04:18 +00004790- Issue #5920: For float.__format__, change the behavior with the
4791 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4792 to be like 'g' but with at least one decimal point and with a
4793 default precision of 12. Previously, the behavior the same but with
4794 a default precision of 6. This more closely matches str(), and
4795 reduces surprises when adding alignment flags to the empty
4796 presentation type. This also affects the new complex.__format__ in
4797 the same way.
4798
Martin v. Löwis011e8422009-05-05 04:43:17 +00004799- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4800
R. David Murrayb18500d2009-05-04 22:59:07 +00004801- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4802 shadowed by classtype's, even if it was None. property now
4803 inserts the __doc__ into the subclass instance __dict__.
4804
Antoine Pitrou244651a2009-05-04 18:56:13 +00004805- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4806 sequences. Patch by Nick Barnes and Victor Stinner.
4807
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004808- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004809
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004810- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4811 received a new method, detach(). detach() disconnects the underlying stream
4812 from the buffer or text IO and returns it.
4813
Mark Dickinson33841c32009-05-01 15:37:04 +00004814- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4815 floats with absolute value over 1e50. Also remove length
4816 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4817 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004818
Eric Smith741191f2009-05-06 13:08:15 +00004819- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004820 format(complex(1, 2./3), '.5') now produces a sensible result.
4821
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004822- Issue #5864: Fix empty format code formatting for floats so that it
4823 never gives more than the requested number of significant digits.
4824
Eric Smith6dc46f52009-04-27 20:39:49 +00004825- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4826 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4827
Eric Smithcc32a112009-04-26 21:35:14 +00004828- Issue #5835: Deprecate PyOS_ascii_formatd.
4829
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004830- Issue #4971: Fix titlecase for characters that are their own
4831 titlecase, but not their own uppercase.
4832
Benjamin Peterson193152c2009-04-25 01:08:45 +00004833- Issue #5283: Setting __class__ in __del__ caused a segfault.
4834
Mark Dickinsonad476da2009-04-23 19:14:16 +00004835- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4836 z involves nans, infs or negative zeros.
4837
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004838- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004839
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004840- Issue #1869 (and many duplicates): make round(x, n) correctly
4841 rounded for a float x, by using the decimal <-> binary conversions
4842 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4843 consistently agrees with format(x, '.2f').
4844
Benjamin Petersonae937c02009-04-18 20:54:08 +00004845- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4846 some builtin types.
4847
Eric Smith0923d1d2009-04-16 20:16:10 +00004848- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4849
Eric Smith35e84722009-04-16 20:21:28 +00004850- Issue #5515: str.format() type 'n' combined with commas and leading
4851 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004852
4853- Implement PEP 378, Format Specifier for Thousands Separator, for
4854 floats.
4855
Mark Dickinson3370cce2009-04-17 22:40:53 +00004856- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004857 1e11, not 1e12. This avoids printing 13 significant digits in
4858 situations where only 12 of them are correct. Example problem
4859 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4860 long time.)
4861
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004862- Issue #1580: On most platforms, use a 'short' float repr: for a
4863 finite float x, repr(x) now outputs a string based on the shortest
4864 sequence of decimal digits that rounds to x. Previous behaviour was
4865 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004866 Another minor difference is that the new repr switches to
4867 exponential notation at 1e16 instead of the previous 1e17; this
4868 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004869
4870 There's a new sys attribute sys.float_repr_style, which takes
4871 the value 'short' to indicate that we're using short float repr,
4872 and 'legacy' if the short float repr isn't available for one
4873 reason or another.
4874
4875 The float repr change involves incorporating David Gay's 'perfect
4876 rounding' code into the Python core (it's in Python/dtoa.c). As a
4877 secondary consequence, all string-to-float and float-to-string
4878 conversions (including all float formatting operations) will be
4879 correctly rounded on these platforms.
4880
Georg Brandl5f90d792010-08-01 22:31:05 +00004881 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004882 this change does not apply.
4883
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004884- Issue #5759: float() didn't call __float__ on str subclasses.
4885
Georg Brandlabc38772009-04-12 15:51:51 +00004886- The string.maketrans() function is deprecated; there is a new static method
4887 maketrans() on the bytes and bytearray classes. This removes confusion about
4888 the types string.maketrans() is supposed to work with, and mirrors the
4889 methods available on the str class.
4890
R. David Murraydc6da8a2009-04-09 22:16:43 +00004891- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4892 its clarity and its speed.
4893
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004894- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004895 to avoid compiler warnings.
4896
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004897- Issue #3739: The unicode-internal encoder now reports the number of characters
4898 consumed like any other encoder (instead of the number of bytes).

5036
Benjamin Peterson7fe98532009-04-02 00:33:55 +00005037- Issue #5499: The 'c' code for argument parsing functions now only accepts a
5038 byte, and the 'C' code only accepts a unicode character.
5039
Georg Brandl406b3d82009-04-11 21:24:37 +00005040- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
5041 when hitting the recursion limit under certain circumstances.
5042
Brett Cannon0759dd62009-04-01 18:13:07 +00005043- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
5044
Georg Brandlab6f2f62009-03-31 04:16:10 +00005045- Fix a segfault when running test_exceptions with coverage, caused by
5046 insufficient checks in accessors of Exception.__context__.
5047
Guido van Rossum0ad59d42009-03-30 22:01:35 +00005048- Issue #5604: non-ASCII characters in module name passed to
5049 imp.find_module() were converted to UTF-8 while the path is
5050 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00005052- Issue #5126: str.isprintable() returned False for space characters.
5053
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00005054- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5055 the end sys.path, for compatibility with the system install of Python.
5056
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005057- Issue #4688: Add a heuristic so that tuples and dicts containing only
5058 untrackable objects are not tracked by the garbage collector. This can
5059 reduce the size of collections and therefore the garbage collection overhead
5060 on long-running programs, depending on their particular use of datatypes.
5061
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005062- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5074 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
5075 and sizeof(Py_UNICODE) == 2.
5076
Eric Smith8ec90442009-03-14 12:29:34 +00005077- Issue #5237: Allow auto-numbered fields in str.format(). For

5079
Antoine Pitrou652e7072009-03-13 19:25:20 +00005080- Issue #5392: when a very low recursion limit was set, the interpreter would
5081 abort with a fatal error after the recursion limit was hit twice.
5082
Matthias Klose042f1332009-04-04 14:32:42 +00005083- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

5129
Lars Gustäbel42e00912009-03-22 20:34:29 +00005130- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5131 forever on incomplete input. That caused tarfile.open() to hang when used
5132 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5133 partial bzip2 compressed data.
5134
Mark Dickinson79f52032009-03-17 23:12:51 +00005135- Issue #2110: Add support for thousands separator and 'n' type

5151
Mark Dickinsonae681df2009-03-21 10:26:31 +00005152- Issue #5463: In struct module, remove deprecated overflow wrapping
5153 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005154 struct.error instead of returning b'\xff\xff\xff\xff'. The
5155 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5156 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005183- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5184 it now forces its argument to double before testing for infinity.
5185
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005186- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5187 returns a non-number type.
5188
Benjamin Peterson87618552009-02-08 15:00:52 +00005189- Issue #5182: Removed memoryview.__str__.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005196- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005197 were suppressing all exceptions. These include list() and bytearray().
5198
Mark Dickinson1124e712009-01-28 21:25:58 +00005199- Issue #4707: round(x, n) now returns an integer if x is an integer.
5200 Previously it returned a float.
5201
Antoine Pitroub52ec782009-01-25 16:34:23 +00005202- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5203 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5204 evaluation loop is compiled with a new dispatch mechanism which gives
5205 speedups of up to 20%, depending on the system, on various benchmarks.

Georg Brandl65ce6ad2010-09-05 17:32:31 +00005218 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005219
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005220- Issue #4935: The overflow checking code in the expandtabs() method common
5221 to str, bytes and bytearray could be optimized away by the compiler, letting
5222 the interpreter segfault instead of raising an error.
5223
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005224- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou8043cf82009-01-09 19:54:29 +00005246 having been closed (for instance, a read() call could return some
5247 previously buffered data). Patch by Dmitry Vasiliev.
5248
Antoine Pitrou05608432009-01-09 18:53:14 +00005249- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5250 flag to work properly. Furthermore, when specifying -u, the text stdout
5251 and stderr streams have line-by-line buffering enabled (the default being
5252 to buffer arbitrary chunks of data).
5253
Raymond Hettinger35631532009-01-09 03:58:09 +00005254- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5255 instead of ints (reducing its size from 4 to 8 times thereby reducing
5256 Python's overall memory).
5257
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005258- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5259 an existing .py counterpart, override the co_filename attributes of all
5260 code objects if the original filename is obsolete (which can happen if the
5261 file has been renamed, moved, or if it is accessed through different paths).
5262 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5263
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005264- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5265 one byte. Also fixes the meaning of len() so that it returns the number of
5266 items, rather than the size in bytes.
5267
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005268- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5269
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005270- Issue #4747: When the terminal does not use utf-8, executing a script with

5278
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005279- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5280 where the tp_hash and tp_dict slots are both NULL.
5281
Georg Brandlccc47b62008-12-28 11:44:14 +00005282- Issue #4759: None is now allowed as the first argument of
5283 bytearray.translate(). It was always allowed for bytes.translate().
5284
Skip Montanaro80072cb2008-12-23 03:51:14 +00005285- Added test case to ensure attempts to read from a file opened for writing
5286 fail.

5334 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

5336 of using the replace error handler in PyUnicode_DecodeUTF8().

5655
Antoine Pitrou08838b62009-01-21 00:55:13 +00005656- Issue #5008: When a file is opened in append mode with the new IO library,
5657 do an explicit seek to the end of file (so that e.g. tell() returns the

5689 appropriately when it is being used via socket.makefile() objects
5690 rather than delaying the close by waiting for garbage collection to do it.
5691
Raymond Hettingerb8baf632009-01-14 02:20:07 +00005692- Issue #1696199: Add collections.Counter() for rapid and convenient
