426 Condition, etc.) used to be factory functions returning instances of hidden
427 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this
428 code pre-dates the ability to subclass extension types. It is now possible to
429 inherit from Thread and other classes, without having to import the private
430 underscored names like multiprocessing did.

Antoine Pitroud42c1d02011-07-23 21:50:21 +0200460 a read1() method), and add a *write_through* parameter to mandate
461 unbuffered writes.
Antoine Pitroue96ec682011-07-23 21:46:35 +0200462

470 to get channel binding data for the current SSL session (only the
471 "tls-unique" channel binding is implemented). This allows the implementation

575 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
576 interpreter process. This could cause failures in non-Distutils subprocesses

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001791- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001792 continuation line in the formatted value has no leading white space and looks
1793 like a header. Since Generator uses Header to format all headers, this check
1794 is made for all headers in any serialized message at serialization time. This
1795 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001796

Éric Araujof0ab5d62011-05-29 03:43:59 +02001804 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001805 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001806
Éric Araujof0ab5d62011-05-29 03:43:59 +02001807- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001808 rfc2047-encoding header values with embedded newlines, leaving them without
1809 folding whitespace. It now uses the continuation_ws, as it does for
1810 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001812- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1813 time.asctime(), time.ctime() and time.strftime() functions will now format

1815 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1816 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1817 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002450 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002451 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002796- Issue #10068: Global objects which have reference cycles with their module's
2797 dict are now cleared again. This causes issue #7140 to appear again.
2798
Victor Stinner257d38f2010-10-09 10:12:11 +00002799- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002800 encodings.

Georg Brandl27a28582010-10-10 09:49:21 +00002802- ast.literal_eval() can now handle negative numbers. It is also a little more
2803 liberal in what it accepts without compromising the safety of the evaluation.
2804 For example, 3j+4 and 3+4+5 are both accepted.

2808
Victor Stinneraef57e32010-10-02 11:50:49 +00002809- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2810
Victor Stinner5593d8a2010-10-02 11:11:27 +00002811- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002812 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

2822
Georg Brandl27a28582010-10-10 09:49:21 +00002823- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002826- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002827 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

2830
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002831- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2832 threads are still running. Instead, reinitialize the GIL on a second call to
2833 Py_Initialize().
2834
Georg Brandl27a28582010-10-10 09:49:21 +00002835- All SyntaxErrors now have a column offset and therefore a caret when the error
2836 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002837
Brett Cannonbc2eff32010-09-19 21:39:02 +00002838- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2839 module that was imported, but instead gets the module from sys.modules.
2840
Nick Coghlan37ee8502010-12-03 14:26:13 +00002841- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002842 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00002844- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2845 with a non-empty format string. This is an effort to future-proof user
2846 code. If a derived class does not currently implement __format__ but later
2847 adds its own __format__, it would most likely break user code that had
2848 supplied a format string. This will be changed to a DeprecationWaring in
2849 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002850
Antoine Pitrou1df15362010-09-13 14:16:46 +00002851- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2852 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2853 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2854
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002855- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2856 functions from the libc caused the methods .upper() and lower() to become
2857 locale aware and created subtly wrong results.
2858
Georg Brandl27a28582010-10-10 09:49:21 +00002859- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2860 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002861
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002862- Issue #4617: Previously it was illegal to delete a name from the local
2863 namespace if it occurs as a free variable in a nested block. This limitation
2864 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2865
Georg Brandl27a28582010-10-10 09:49:21 +00002866- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2867 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2868 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2869 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002870
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002871- Issue #9757: memoryview objects get a release() method to release the
2872 underlying buffer (previously this was only done when deallocating the
2873 memoryview), and gain support for the context management protocol.
2874
Antoine Pitrou079ce542010-09-08 12:37:10 +00002875- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2876 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002892- Issue #4661: email can now parse bytes input and generate either converted

2894
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002895- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2903
Éric Araujoef777bd2010-10-05 00:04:20 +00002904- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002905 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002906 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002907 replacement for old handle_accept() and avoids the user to call accept()
2908 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002932 retry the select() loop instead of bailing out. This is because select() can
2933 incorrectly report a socket as ready for reading (for example, if it received
2934 some data with an invalid checksum).

Georg Brandl27a28582010-10-10 09:49:21 +00002981 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003014- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003015 it possible for the user to create self-referencing ordered dictionaries which
3016 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003017 approach of using weakref proxies so that reference cycles never get created
3018 in the first place.

3026 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3027 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003028
Georg Brandl27a28582010-10-10 09:49:21 +00003029- Issue #9410: Various optimizations to the pickle module, leading to speedups

Antoine Pitrou783eea72010-09-07 22:06:17 +00003042
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003043- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3044 still return the id of the parent process after it has exited. This process
3045 id may even have been reused by another unrelated process.
3046
Georg Brandl27a28582010-10-10 09:49:21 +00003047- Issue #9792: In case of connection failure, socket.create_connection() would
3048 swallow the exception and raise a new one, making it impossible to fetch the
3049 original errno, or to filter timeout errors. Now the original error is
3050 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003052- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3053 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3054 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003056- Updates to the random module:
3057
Georg Brandl27a28582010-10-10 09:49:21 +00003058 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003061 * Update the seed() method to use all of the bits in a string instead of just
3062 the hash value. This makes better use of the seed value and assures the
3063 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003065 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3066 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3067 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003068
3069 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003088- hashlib has two new constant attributes: algorithms_guaranteed and
3089 algorithms_avaiable that respectively list the names of hash algorithms
3090 guaranteed to exist in all Python implementations and the names of hash
3091 algorithms available in the current process.

Georg Brandl62069d32010-07-31 08:56:11 +00003604 start byte and the continuation byte(s) are now considered invalid, instead of
3605 the number of bytes specified by the start byte. E.g.:

3607 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3608 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3609 returned a single u'\ufffd'.

3682 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003683 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.

4016 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4017 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004018 to match the behaviour of the other integer format codes.

4047 gives improved memory leak detection when running under Valgrind, while taking
4048 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004121- The default size of the re module's compiled regular expression cache has been
4122 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004123 simply clearing the entire cache on overflow to forgetting the least recently
4124 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004125 applications that use a lot of regular expressions and limits the impact of
4126 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004138- Issue #7989: Added pure python implementation of the `datetime` module. The C
4139 module is renamed to `_datetime` and if available, overrides all classes
4140 defined in datetime with fast C impementation. Python implementation is based
4141 on the original python prototype for the datetime module by Tim Peters with
4142 minor modifications by the PyPy project. The test suite now tests `datetime`
4143 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004380- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4381 operation raises multiple signals and more than one of those signals is
4382 trapped, the specification determines the order in which the signals should be
4383 handled. In many cases this order wasn't being followed, leading to the wrong

4424 socket wasn't retained (instead, a socket with a positive timeout would be
4425 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004426
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004427- Issue #5103: SSL handshake would ignore the socket timeout and block

Georg Brandl62069d32010-07-31 08:56:11 +00004540- Issue #2531: Comparison operations between floats and Decimal instances now
4541 return a result based on the numeric values of the operands; previously they
4542 returned an arbitrary result based on the relative ordering of id(float) and

Georg Brandl62069d32010-07-31 08:56:11 +00004887 default when instantiating a `threading.RLock` object. This makes recursive
4888 locks as fast as regular non-recursive locks (previously, they were slower by
4889 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00005042 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5043 PyPycLoader inherit from this class and provide implementations in relation to
5044 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00005045
Brett Cannon64ef00f2009-07-20 03:19:18 +00005046- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5047 the documentation said it did even though the code in PyLoader relied on the
5048 abstract method required by ResourceLoader.

Mark Dickinsoncf28b952010-07-29 21:41:59 +00005101- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
5102
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005103- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005104 compared to other unix systems. In particular, os.getgroups() does not reflect
5105 any changes made using os.setgroups() but basicly always returns the same
5106 information as the id command. os.getgroups() can now return more than 16
5107 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005108

Georg Brandl62069d32010-07-31 08:56:11 +00005132- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5133 Prior to this change, timezone adjustment in utctimetuple() could produce
5134 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5135 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005137- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5138 directive. When the ``%z`` directive is present in the format string, an
5139 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5140 ``datetime.timezone`` instance constructed from the parsed offset. If both
5141 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5142 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005144- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005145 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5146 ``datetime.timezone``, return fixed name and UTC offset from their
5147 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5148 returns ``None``. A class attribute, ``utc`` contains an instance
5149 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00005165- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5166 with an improved 'binary-split' algorithm that uses fewer multiplications and
5167 allows many of the multiplications to be performed using plain C integer
5168 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005174- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5175 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005176 the result is now always correctly rounded, and is equivalent to ``td /
5177 timedelta(seconds=1)``.

5186 integer format code, struct.pack first attempts to convert the non-integer
5187 using its __index__ method. If that method is non-existent or raises
5188 TypeError it goes on to try the __int__ method, as described below.

5463 threads could return successfully while some Thread objects were still
5464 referenced. This also introduces a new private function:

5769 default precision of 12. Previously, the behavior the same but with
5770 a default precision of 6. This more closely matches str(), and
5771 reduces surprises when adding alignment flags to the empty
5772 presentation type. This also affects the new complex.__format__ in
5773 the same way.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005816- Issue #1869 (and many duplicates): make round(x, n) correctly
5817 rounded for a float x, by using the decimal <-> binary conversions
5818 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5819 consistently agrees with format(x, '.2f').
5820
Benjamin Petersonae937c02009-04-18 20:54:08 +00005821- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5825
Eric Smith35e84722009-04-16 20:21:28 +00005826- Issue #5515: str.format() type 'n' combined with commas and leading
5827 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005828
5829- Implement PEP 378, Format Specifier for Thousands Separator, for
5830 floats.
5831
Mark Dickinson3370cce2009-04-17 22:40:53 +00005832- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005833 1e11, not 1e12. This avoids printing 13 significant digits in
5834 situations where only 12 of them are correct. Example problem
5835 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5836 long time.)
5837
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005838- Issue #1580: On most platforms, use a 'short' float repr: for a
5839 finite float x, repr(x) now outputs a string based on the shortest
5840 sequence of decimal digits that rounds to x. Previous behaviour was
5841 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005842 Another minor difference is that the new repr switches to
5843 exponential notation at 1e16 instead of the previous 1e17; this
5844 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005845
5846 There's a new sys attribute sys.float_repr_style, which takes
5847 the value 'short' to indicate that we're using short float repr,
5848 and 'legacy' if the short float repr isn't available for one
5849 reason or another.
5850
5851 The float repr change involves incorporating David Gay's 'perfect
5852 rounding' code into the Python core (it's in Python/dtoa.c). As a
5853 secondary consequence, all string-to-float and float-to-string
5854 conversions (including all float formatting operations) will be
5855 correctly rounded on these platforms.
5856
Georg Brandl5f90d792010-08-01 22:31:05 +00005857 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005858 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005860- Issue #5759: float() didn't call __float__ on str subclasses.
5861
Georg Brandlabc38772009-04-12 15:51:51 +00005862- The string.maketrans() function is deprecated; there is a new static method
5863 maketrans() on the bytes and bytearray classes. This removes confusion about
5864 the types string.maketrans() is supposed to work with, and mirrors the
5865 methods available on the str class.
5866
R. David Murraydc6da8a2009-04-09 22:16:43 +00005867- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

6034 untrackable objects are not tracked by the garbage collector. This can
6035 reduce the size of collections and therefore the garbage collection overhead
6036 on long-running programs, depending on their particular use of datatypes.

6044 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6045 --enable-big-digits option to configure, which overrides the
6046 default. Add sys.int_info structseq to provide information about
6047 the internal format.

6101 (typically /dev/zero under Unix) could crash the interpreter.
6102
Benjamin Peterson59406a92009-03-26 17:10:29 +00006103- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
6104 io.BufferedRandom have been deprecated for removal in Python 3.2.
6105
Lars Gustäbel42e00912009-03-22 20:34:29 +00006106- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6107 forever on incomplete input. That caused tarfile.open() to hang when used
6108 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6109 partial bzip2 compressed data.

6115 '>' alignment characters.
6116
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00006117- The error detection code in FileIO.close() could fail to reflect the `errno`

Mark Dickinsonae681df2009-03-21 10:26:31 +00006128- Issue #5463: In struct module, remove deprecated overflow wrapping
6129 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00006130 struct.error instead of returning b'\xff\xff\xff\xff'. The
6131 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
6132 have been removed from the struct module.

6148 used when using str.format() with str, int, and float arguments.
6149
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006150- Issue #5249: time.strftime returned malformed string when format string
6151 contained non ascii character on windows.
6152
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006153- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6154 source has already been decoded into str.
6155
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006156- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6157 rotating the object pointer by 4 bits to the right.
6158
Mark Dickinson87ec0852009-02-09 17:15:59 +00006159- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6160 it now forces its argument to double before testing for infinity.
6161
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006162- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6163 returns a non-number type.
6164
Benjamin Peterson87618552009-02-08 15:00:52 +00006165- Issue #5182: Removed memoryview.__str__.
6166
Mark Dickinsonc008a172009-02-01 13:59:22 +00006167- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6168 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006169 the type definition cmpfunc. The tp_compare slot has been renamed
6170 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006171
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006172- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006173 were suppressing all exceptions. These include list() and bytearray().
6174
Mark Dickinson1124e712009-01-28 21:25:58 +00006175- Issue #4707: round(x, n) now returns an integer if x is an integer.
6176 Previously it returned a float.
6177
Antoine Pitroub52ec782009-01-25 16:34:23 +00006178- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6179 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6180 evaluation loop is compiled with a new dispatch mechanism which gives
6181 speedups of up to 20%, depending on the system, on various benchmarks.
6182
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006183- Issue #4874: Most builtin decoders now reject unicode input.

6189
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006190- Issue #4838: When a module is deallocated, free the memory backing the
6191 optional module state data.
6192
Mark Dickinson8055afd2009-01-17 10:04:45 +00006193- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006194 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006195
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006196- Issue #4935: The overflow checking code in the expandtabs() method common
6197 to str, bytes and bytearray could be optimized away by the compiler, letting
6198 the interpreter segfault instead of raising an error.
6199
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006200- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6201 __next__ method.
6202
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006203- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6204 function no longer attempt to call the __long__ slot to convert an object
6205 to an integer. Only the __int__ and __trunc__ slots are examined.
6206
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006207- Issue #4893: Use NT threading on CE.
6208

6210
Antoine Pitrouab868312009-01-10 15:40:25 +00006211- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6212 common cases are optimized thanks to a dedicated fast path and a moderate
6213 amount of loop unrolling.
6214
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006215- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6216 collecting the oldest generation) so that allocating lots of objects without
6217 destroying them does not show quadratic performance. Based on a proposal by
6218 Martin von Löwis at
6219 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6220
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006221- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006222 having been closed (for instance, a read() call could return some
6223 previously buffered data). Patch by Dmitry Vasiliev.
6224
Antoine Pitrou05608432009-01-09 18:53:14 +00006225- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6226 flag to work properly. Furthermore, when specifying -u, the text stdout
6227 and stderr streams have line-by-line buffering enabled (the default being
6228 to buffer arbitrary chunks of data).
6229
Raymond Hettinger35631532009-01-09 03:58:09 +00006230- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6231 instead of ints (reducing its size from 4 to 8 times thereby reducing
6232 Python's overall memory).
6233
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006234- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6235 an existing .py counterpart, override the co_filename attributes of all
6236 code objects if the original filename is obsolete (which can happen if the
6237 file has been renamed, moved, or if it is accessed through different paths).
6238 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6239
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006240- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6241 one byte. Also fixes the meaning of len() so that it returns the number of
6242 items, rather than the size in bytes.
6243
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006244- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6245
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006246- Issue #4747: When the terminal does not use utf-8, executing a script with
6247 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6248
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006249- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6250 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006251
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006252- Issue #3680: Reference cycles created through a dict, set or deque iterator
6253 did not get collected.
6254
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006255- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6256 where the tp_hash and tp_dict slots are both NULL.
6257
Georg Brandlccc47b62008-12-28 11:44:14 +00006258- Issue #4759: None is now allowed as the first argument of
6259 bytearray.translate(). It was always allowed for bytes.translate().
6260
Skip Montanaro80072cb2008-12-23 03:51:14 +00006261- Added test case to ensure attempts to read from a file opened for writing
6262 fail.
6263
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006264- Issue #3106: Speedup some comparisons (str/str and int/int).

6268
Antoine Pitrou621601a2008-12-17 23:18:19 +00006269- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6270 print elapsed times, not only when some objects are uncollectable /
6271 unreachable. Original patch by Neil Schemenauer.
6272
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006273- Issue #3439: Add a bit_length method to int.
6274
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006275- Issue #2173: When getting device encoding, check that return value of
6276 nl_langinfo is not the empty string. This was causing silent build
6277 failures on OS X.
6278
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006279- Issue #4597: Fixed several opcodes that weren't always propagating
6280 exceptions.
6281
6282- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006283 context manager returns a value that cannot be converted to a bool.
6284
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006285- Issue #4445: Replace "sizeof(PyBytesObject)" with
6286 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6287 bytes instances. On a typical machine this saves 3 bytes of memory
6288 (on average) per allocation of a bytes instance.
6289
Christian Heimesa872de52008-12-05 08:26:55 +00006290- Issue #4533: File read operation was dreadfully slow due to a slowly
6291 growing read buffer. Fixed by using the same growth rate algorithm as
6292 Python 2.x.
6293
Antoine Pitrou5504e892008-12-06 21:27:53 +00006294- Issue #4509: Various issues surrounding resize of bytearray objects to
6295 which there are buffer exports (e.g. memoryview instances).
6296
Georg Brandlf9734072008-12-07 15:30:06 +00006297- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6298 method on file objects with closefd=False. The file descriptor is still
6299 kept open but the file object behaves like a closed file. The ``FileIO``
6300 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006301
Antoine Pitroubc420402008-12-07 20:14:49 +00006302- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6303 larger than 1.

6308
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006309- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6310 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6311 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6312 of using the replace error handler in PyUnicode_DecodeUTF8().
