602 keyword-only argument. The preceding positional argument was deprecated,
603 so it made no sense to add filter as a positional argument.

Victor Stinner4ee65a92011-01-22 10:30:29 +0000618 filenames, at bootstrap, if the codec registry is not ready yet. It is still
619 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)

629
Armin Ronacher8d96d772011-01-22 13:13:05 +0000630- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
631 encoding. This is the preferred encoding of PEP 3333 and the base encoding
632 of HTTP 1.1.
633
Armin Ronacher59531282011-01-22 13:44:22 +0000634- To match the behaviour of HTTP server, the HTTP client library now also
635 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
636 that for incoming headers which makes this behaviour now consistent in
637 both incoming and outgoing direction.

Georg Brandl255abdd2011-01-16 14:17:26 +0000673- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
674 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
675 translates newlines (\r\n => \n).

Georg Brandl255abdd2011-01-16 14:17:26 +0000705- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
706 than the currently problematic Apple-supplied one, when running with the
707 64-/32-bit installer variant.

R. David Murray5b2d9dd2011-01-09 02:35:24 +0000727- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +0000728 continuation line in the formatted value has no leading white space and looks
729 like a header. Since Generator uses Header to format all headers, this check
730 is made for all headers in any serialized message at serialization time. This
731 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000732
Antoine Pitrou67b212e2011-01-08 09:55:31 +0000733- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

R. David Murray92532142011-01-07 23:25:30 +0000739- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Georg Brandl255abdd2011-01-16 14:17:26 +0000740 non-ASCII bytes (parsed by a Bytes Parser) when doing conversion to 7bit-clean
741 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +0000742
R. David Murray6f0022d2011-01-07 21:57:25 +0000743- email.header.Header was incorrectly encoding folding white space when
Georg Brandl255abdd2011-01-16 14:17:26 +0000744 rfc2047-encoding header values with embedded newlines, leaving them without
745 folding whitespace. It now uses the continuation_ws, as it does for
746 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +0000748- Issue #1777412, #10827: Changed the rules for 2-digit years. The
749 time.asctime(), time.ctime() and time.strftime() functions will now format
750 any year when ``time.accept2dyear`` is False and will accept years >= 1000
751 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
752 supported by the OS. With Visual Studio or on Solaris, the year is limited to
753 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

763
Antoine Pitrou600232b2011-01-05 21:03:42 +0000764- Issue #7995: When calling accept() on a socket with a timeout, the returned

1766
Georg Brandl27a28582010-10-10 09:49:21 +00001767- All SyntaxErrors now have a column offset and therefore a caret when the error

1777 with a non-empty format string. This is an effort to future-proof user
1778 code. If a derived class does not currently implement __format__ but later
1779 adds its own __format__, it would most likely break user code that had
1780 supplied a format string. This will be changed to a DeprecationWaring in
1781 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00001783- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

1785 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 +00001787- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1788 functions from the libc caused the methods .upper() and lower() to become
1789 locale aware and created subtly wrong results.
1790
Georg Brandl27a28582010-10-10 09:49:21 +00001791- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1792 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001793
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001794- Issue #4617: Previously it was illegal to delete a name from the local
1795 namespace if it occurs as a free variable in a nested block. This limitation
1796 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1797
Georg Brandl27a28582010-10-10 09:49:21 +00001798- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1799 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1800 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1801 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001803- Issue #9757: memoryview objects get a release() method to release the
1804 underlying buffer (previously this was only done when deallocating the
1805 memoryview), and gain support for the context management protocol.
1806
Antoine Pitrou079ce542010-09-08 12:37:10 +00001807- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00001836- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001837 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001838 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001839 replacement for old handle_accept() and avoids the user to call accept()

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00001861- Issue #9962: GzipFile now has the peek() method.
1862
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001863- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001864 retry the select() loop instead of bailing out. This is because select() can
1865 incorrectly report a socket as ready for reading (for example, if it received
1866 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00001871 received. Now sendall() properly calls signal handlers if necessary, and
1872 retries sending if these returned successfully, including on sockets with a
1873 timeout.

1911
Antoine Pitrou98b46702010-09-18 22:59:00 +00001912- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00001913 non-blocking mode: they return None when an operation would block (instead of
1914 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00001915
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00001916- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Georg Brandl27a28582010-10-10 09:49:21 +00001926- Issue #1552: socket.socketpair() now returns regular socket.socket objects
1927 supporting the whole socket API (rather than the "raw" _socket.socket
1928 objects).
Antoine Pitrou9e0b8642010-09-14 18:00:02 +00001929

Raymond Hettingerfa11db02010-09-12 04:12:42 +00001946- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001947 it possible for the user to create self-referencing ordered dictionaries which
1948 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001949 approach of using weakref proxies so that reference cycles never get created
1950 in the first place.
1951
Victor Stinnercb043522010-09-10 23:49:04 +00001952- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
1953 encode the value with filesystem encoding and surrogateescape (instead of

Victor Stinnercb043522010-09-10 23:49:04 +00001955
Georg Brandl27a28582010-10-10 09:49:21 +00001956- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
1957 environment variable to set the filesystem encoding at Python startup.
1958 sys.setfilesystemencoding() creates inconsistencies because it is unable to
1959 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00001960
Georg Brandl27a28582010-10-10 09:49:21 +00001961- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00001968- Logging: Added QueueHandler class to facilitate logging usage with
1969 multiprocessing.
1970
Georg Brandl27a28582010-10-10 09:49:21 +00001971- Issue #9707: Rewritten reference implementation of threading.local which is
1972 friendlier towards reference cycles. This change is not normally visible
1973 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00001974
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001975- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1976 still return the id of the parent process after it has exited. This process
1977 id may even have been reused by another unrelated process.
1978
Georg Brandl27a28582010-10-10 09:49:21 +00001979- Issue #9792: In case of connection failure, socket.create_connection() would
1980 swallow the exception and raise a new one, making it impossible to fetch the
1981 original errno, or to filter timeout errors. Now the original error is
1982 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00001983
Georg Brandl27a28582010-10-10 09:49:21 +00001984- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
1985 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
1986 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00001987
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001988- Updates to the random module:
1989
Georg Brandl27a28582010-10-10 09:49:21 +00001990 * Document which parts of the module are guaranteed to stay the same across
1991 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00001993 * Update the seed() method to use all of the bits in a string instead of just
1994 the hash value. This makes better use of the seed value and assures the
1995 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00001996
Georg Brandl27a28582010-10-10 09:49:21 +00001997 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1998 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1999 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002000
2001 * Improved documentation of arguments to randrange(). Issue #9379.

Georg Brandl27a28582010-10-10 09:49:21 +00002017 unsupported operation is attempted (for example, writing to a file open only
2018 for reading).
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002019
Gregory P. Smith13b55292010-09-06 08:30:23 +00002020- hashlib has two new constant attributes: algorithms_guaranteed and
2021 algorithms_avaiable that respectively list the names of hash algorithms
2022 guaranteed to exist in all Python implementations and the names of hash
2023 algorithms available in the current process.
2024

2114
Georg Brandl649971e2010-09-05 17:06:50 +00002115- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2116 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2117 bytecode is a bit simplified. Patch by Demur Rumed.
Antoine Pitrou74a69fa2010-09-04 18:43:52 +00002118
Brett Cannonef0e6c32010-09-04 18:24:04 +00002119- Issue #9766: Rename poorly named variables exposed by _warnings to prevent

2121
Georg Brandl649971e2010-09-05 17:06:50 +00002122- Issue #9212: dict_keys and dict_items now provide the isdisjoint() method, to
2123 conform to the Set ABC. Patch by Daniel Urban.
Daniel Stutzbach045b3ba2010-09-02 15:06:06 +00002124
Georg Brandl649971e2010-09-05 17:06:50 +00002125- Issue #9737: Fix a crash when trying to delete a slice or an item from a
2126 memoryview object.
Antoine Pitroue0793ba2010-09-01 21:14:16 +00002127
Georg Brandl649971e2010-09-05 17:06:50 +00002128- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2129 now removed, since their effect was inexistent in 3.x (the default encoding is
2130 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002131
Antoine Pitroub0fa8312010-09-01 15:10:12 +00002132- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
2133 properly. Patch by Stefan Behnel.
2134
Georg Brandl649971e2010-09-05 17:06:50 +00002135- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
2136 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00002137
Benjamin Peterson33856de2010-08-30 14:41:20 +00002138- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
2139
Benjamin Peterson0e102062010-08-25 23:13:17 +00002140- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
2141
Georg Brandl649971e2010-09-05 17:06:50 +00002142- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
2143 the pyconfig.h generated by configure on other systems.
Daniel Stutzbach864078a2010-08-25 19:18:59 +00002144
Georg Brandl649971e2010-09-05 17:06:50 +00002145- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
2146 occur during attribute lookup are now propagated to the caller.
Benjamin Peterson17689992010-08-24 03:26:23 +00002147

2150
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00002151- Issue #5127: The C functions that access the Unicode Database now accept and
2152 return characters from the full Unicode range, even on narrow unicode builds
2153 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2154 in Python is that unicodedata.numeric() now returns the correct value for
2155 large code points, and repr() may consider more characters as printable.
2156
Victor Stinner6c00c142010-08-17 23:37:11 +00002157- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
2158 as a unicode object, instead of a byte string. Function needed to support
2159 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2160 function.
2161
Victor Stinner6961bd62010-08-17 22:26:51 +00002162- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().
2163
Antoine Pitrou671b4d92010-08-17 17:55:07 +00002164- Issue #9612: The set object is now 64-bit clean under Windows.
2165
Georg Brandl649971e2010-09-05 17:06:50 +00002166- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
2167 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00002168

2170 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +00002171 sys.stderr.
2172
Victor Stinner47fcb5b2010-08-13 23:59:58 +00002173- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002174 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2175 objects are output as-is.
Victor Stinner47fcb5b2010-08-13 23:59:58 +00002176
Georg Brandl649971e2010-09-05 17:06:50 +00002177- Issue #9203: Computed gotos are now enabled by default on supported compilers
2178 (which are detected by the configure script). They can still be disable
2179 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00002180
Georg Brandl649971e2010-09-05 17:06:50 +00002181- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
2182 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00002183
Georg Brandl649971e2010-09-05 17:06:50 +00002184- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
2185 array.
Florent Xiclunaeb6f3ea2010-08-08 22:07:16 +00002186
Georg Brandl649971e2010-09-05 17:06:50 +00002187- Issue #5319: Print an error if flushing stdout fails at interpreter shutdown.
Antoine Pitroubddc9fe2010-08-08 20:46:42 +00002188
Georg Brandl649971e2010-09-05 17:06:50 +00002189- Issue #9337: The str() of a float or complex number is now identical to its
2190 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00002191
Georg Brandl649971e2010-09-05 17:06:50 +00002192- Issue #9416: Fix some issues with complex formatting where the output with no
2193 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002194
2195 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2196 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2948 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
2949 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00002950 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003053- The default size of the re module's compiled regular expression cache has been
3054 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003055 simply clearing the entire cache on overflow to forgetting the least recently
3056 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003057 applications that use a lot of regular expressions and limits the impact of
3058 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003489- Comparisons using one of <, <=, >, >= between a complex instance and a
3490 Fractions instance now raise TypeError instead of returning True/False. This
3491 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3492 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003962- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal
3963 digits in input, as recommended by the standard. Previously it was restricted
3964 to accepting [0-9].

Brett Cannon69194272009-07-20 04:23:48 +00003973- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00003974 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
3975 PyPycLoader inherit from this class and provide implementations in relation to
3976 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00003977
Brett Cannon64ef00f2009-07-20 03:19:18 +00003978- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
3979 the documentation said it did even though the code in PyLoader relied on the
3980 abstract method required by ResourceLoader.
3981
Georg Brandl62069d32010-07-31 08:56:11 +00003982- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004030- Issue #9959: Tweak formula used for computing math.log of an integer,
4031 making it marginally more accurate for exact powers of 2.

Mark Dickinsoncf28b952010-07-29 21:41:59 +00004033- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
4034
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004035- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004036 compared to other unix systems. In particular, os.getgroups() does not reflect
4037 any changes made using os.setgroups() but basicly always returns the same
4038 information as the id command. os.getgroups() can now return more than 16
4039 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00004064- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4065 Prior to this change, timezone adjustment in utctimetuple() could produce
4066 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4067 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004069- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4070 directive. When the ``%z`` directive is present in the format string, an
4071 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4072 ``datetime.timezone`` instance constructed from the parsed offset. If both
4073 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4074 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004076- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004077 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4078 ``datetime.timezone``, return fixed name and UTC offset from their
4079 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4080 returns ``None``. A class attribute, ``utc`` contains an instance
4081 representing the UTC timezone. Original patch by Rafe Kaplan.

4098 with an improved 'binary-split' algorithm that uses fewer multiplications and
4099 allows many of the multiplications to be performed using plain C integer
4100 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4101 arguments.

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004106- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4107 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004108 the result is now always correctly rounded, and is equivalent to ``td /
4109 timedelta(seconds=1)``.

4118 integer format code, struct.pack first attempts to convert the non-integer
4119 using its __index__ method. If that method is non-existent or raises
4120 TypeError it goes on to try the __int__ method, as described below.

Mark Dickinson865e01a2009-05-07 16:37:01 +00004687- Issue #5914: Add new C API function PyOS_string_to_double, and
4688 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4689
Eric Smith741191f2009-05-06 13:08:15 +00004690- Issue #3382: float.__format__, complex.__format__, and %-formatting
4691 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

4697
Eric Smith63376222009-05-05 14:04:18 +00004698- Issue #5920: For float.__format__, change the behavior with the
4699 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4700 to be like 'g' but with at least one decimal point and with a
4701 default precision of 12. Previously, the behavior the same but with
4702 a default precision of 6. This more closely matches str(), and
4703 reduces surprises when adding alignment flags to the empty
4704 presentation type. This also affects the new complex.__format__ in
4705 the same way.
4706
Martin v. Löwis011e8422009-05-05 04:43:17 +00004707- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00004718- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4719 received a new method, detach(). detach() disconnects the underlying stream
4720 from the buffer or text IO and returns it.
4721
Mark Dickinson33841c32009-05-01 15:37:04 +00004722- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4723 floats with absolute value over 1e50. Also remove length
4724 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4725 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00004727- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004728 format(complex(1, 2./3), '.5') now produces a sensible result.
4729

4732
Eric Smith6dc46f52009-04-27 20:39:49 +00004733- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

4745
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004746- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00004748- Issue #1869 (and many duplicates): make round(x, n) correctly
4749 rounded for a float x, by using the decimal <-> binary conversions
4750 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4751 consistently agrees with format(x, '.2f').
4752
Benjamin Petersonae937c02009-04-18 20:54:08 +00004753- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

4755
Eric Smith0923d1d2009-04-16 20:16:10 +00004756- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4757
Eric Smith35e84722009-04-16 20:21:28 +00004758- Issue #5515: str.format() type 'n' combined with commas and leading
4759 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004760
4761- Implement PEP 378, Format Specifier for Thousands Separator, for
4762 floats.
4763
Mark Dickinson3370cce2009-04-17 22:40:53 +00004764- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004765 1e11, not 1e12. This avoids printing 13 significant digits in
4766 situations where only 12 of them are correct. Example problem
4767 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4768 long time.)
4769
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004770- Issue #1580: On most platforms, use a 'short' float repr: for a
4771 finite float x, repr(x) now outputs a string based on the shortest
4772 sequence of decimal digits that rounds to x. Previous behaviour was
4773 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004774 Another minor difference is that the new repr switches to
4775 exponential notation at 1e16 instead of the previous 1e17; this
4776 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004777
4778 There's a new sys attribute sys.float_repr_style, which takes
4779 the value 'short' to indicate that we're using short float repr,
4780 and 'legacy' if the short float repr isn't available for one
4781 reason or another.
4782
4783 The float repr change involves incorporating David Gay's 'perfect
4784 rounding' code into the Python core (it's in Python/dtoa.c). As a
4785 secondary consequence, all string-to-float and float-to-string
4786 conversions (including all float formatting operations) will be
4787 correctly rounded on these platforms.
4788
Georg Brandl5f90d792010-08-01 22:31:05 +00004789 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004790 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004792- Issue #5759: float() didn't call __float__ on str subclasses.
4793
Georg Brandlabc38772009-04-12 15:51:51 +00004794- The string.maketrans() function is deprecated; there is a new static method
4795 maketrans() on the bytes and bytearray classes. This removes confusion about
4796 the types string.maketrans() is supposed to work with, and mirrors the
4797 methods available on the str class.

5037
Lars Gustäbel42e00912009-03-22 20:34:29 +00005038- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5039 forever on incomplete input. That caused tarfile.open() to hang when used
5040 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5041 partial bzip2 compressed data.
5042
Mark Dickinson79f52032009-03-17 23:12:51 +00005043- Issue #2110: Add support for thousands separator and 'n' type

5061 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005062 struct.error instead of returning b'\xff\xff\xff\xff'. The
5063 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5064 have been removed from the struct module.

5081
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005082- Issue #5249: time.strftime returned malformed string when format string
5083 contained non ascii character on windows.
5084
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005085- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5086 source has already been decoded into str.
5087
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005088- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5089 rotating the object pointer by 4 bits to the right.
5090
Mark Dickinson87ec0852009-02-09 17:15:59 +00005091- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5092 it now forces its argument to double before testing for infinity.
5093
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005094- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5095 returns a non-number type.
5096
Benjamin Peterson87618552009-02-08 15:00:52 +00005097- Issue #5182: Removed memoryview.__str__.
5098
Mark Dickinsonc008a172009-02-01 13:59:22 +00005099- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5100 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005101 the type definition cmpfunc. The tp_compare slot has been renamed
5102 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005103
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005104- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005105 were suppressing all exceptions. These include list() and bytearray().
5106
Mark Dickinson1124e712009-01-28 21:25:58 +00005107- Issue #4707: round(x, n) now returns an integer if x is an integer.
5108 Previously it returned a float.
5109
Antoine Pitroub52ec782009-01-25 16:34:23 +00005110- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5111 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5112 evaluation loop is compiled with a new dispatch mechanism which gives
5113 speedups of up to 20%, depending on the system, on various benchmarks.
5114
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005115- Issue #4874: Most builtin decoders now reject unicode input.

5121
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005122- Issue #4838: When a module is deallocated, free the memory backing the
5123 optional module state data.
5124
Mark Dickinson8055afd2009-01-17 10:04:45 +00005125- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005126 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005127
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005128- Issue #4935: The overflow checking code in the expandtabs() method common
5129 to str, bytes and bytearray could be optimized away by the compiler, letting
5130 the interpreter segfault instead of raising an error.
5131
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005132- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5133 __next__ method.
5134
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005135- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5136 function no longer attempt to call the __long__ slot to convert an object
5137 to an integer. Only the __int__ and __trunc__ slots are examined.
5138
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005139- Issue #4893: Use NT threading on CE.
5140
Martin v. Löwisec59d042009-01-12 07:59:10 +00005141- Issue #4915: Port sysmodule to Windows CE.
5142
Antoine Pitrouab868312009-01-10 15:40:25 +00005143- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5144 common cases are optimized thanks to a dedicated fast path and a moderate
5145 amount of loop unrolling.
5146
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005147- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5148 collecting the oldest generation) so that allocating lots of objects without
5149 destroying them does not show quadratic performance. Based on a proposal by
5150 Martin von Löwis at
5151 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5152
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005153- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005154 having been closed (for instance, a read() call could return some
5155 previously buffered data). Patch by Dmitry Vasiliev.
5156
Antoine Pitrou05608432009-01-09 18:53:14 +00005157- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5158 flag to work properly. Furthermore, when specifying -u, the text stdout
5159 and stderr streams have line-by-line buffering enabled (the default being
5160 to buffer arbitrary chunks of data).
5161
Raymond Hettinger35631532009-01-09 03:58:09 +00005162- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5163 instead of ints (reducing its size from 4 to 8 times thereby reducing
5164 Python's overall memory).
5165
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005166- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5167 an existing .py counterpart, override the co_filename attributes of all
5168 code objects if the original filename is obsolete (which can happen if the
5169 file has been renamed, moved, or if it is accessed through different paths).
5170 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5171
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005172- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5173 one byte. Also fixes the meaning of len() so that it returns the number of
5174 items, rather than the size in bytes.
5175
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005176- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5177
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005178- Issue #4747: When the terminal does not use utf-8, executing a script with
5179 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5180
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005181- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5182 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005183
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005184- Issue #3680: Reference cycles created through a dict, set or deque iterator
5185 did not get collected.
5186
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005187- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5188 where the tp_hash and tp_dict slots are both NULL.
5189
Georg Brandlccc47b62008-12-28 11:44:14 +00005190- Issue #4759: None is now allowed as the first argument of
5191 bytearray.translate(). It was always allowed for bytes.translate().
5192
Skip Montanaro80072cb2008-12-23 03:51:14 +00005193- Added test case to ensure attempts to read from a file opened for writing
5194 fail.
5195
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005196- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00005198- Issue #2183: Simplify and optimize bytecode for list, dict and set
5199 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5200
Antoine Pitrou621601a2008-12-17 23:18:19 +00005201- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5202 print elapsed times, not only when some objects are uncollectable /
5203 unreachable. Original patch by Neil Schemenauer.
5204
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005205- Issue #3439: Add a bit_length method to int.
5206
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005207- Issue #2173: When getting device encoding, check that return value of
5208 nl_langinfo is not the empty string. This was causing silent build
5209 failures on OS X.
5210
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005211- Issue #4597: Fixed several opcodes that weren't always propagating
5212 exceptions.
5213
5214- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005215 context manager returns a value that cannot be converted to a bool.
5216
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005217- Issue #4445: Replace "sizeof(PyBytesObject)" with
5218 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5219 bytes instances. On a typical machine this saves 3 bytes of memory
5220 (on average) per allocation of a bytes instance.
5221
Christian Heimesa872de52008-12-05 08:26:55 +00005222- Issue #4533: File read operation was dreadfully slow due to a slowly
5223 growing read buffer. Fixed by using the same growth rate algorithm as
5224 Python 2.x.
5225
Antoine Pitrou5504e892008-12-06 21:27:53 +00005226- Issue #4509: Various issues surrounding resize of bytearray objects to
5227 which there are buffer exports (e.g. memoryview instances).
5228
Georg Brandlf9734072008-12-07 15:30:06 +00005229- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5230 method on file objects with closefd=False. The file descriptor is still
5231 kept open but the file object behaves like a closed file. The ``FileIO``
5232 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005233
Antoine Pitroubc420402008-12-07 20:14:49 +00005234- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5235 larger than 1.

5240
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005241- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5242 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5243 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5244 of using the replace error handler in PyUnicode_DecodeUTF8().
