705 still possible to globally override the default by setting

708 was built.

Armin Ronacher8d96d772011-01-22 13:13:05 +00001441- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
1442 encoding. This is the preferred encoding of PEP 3333 and the base encoding
1443 of HTTP 1.1.
1444
Armin Ronacher59531282011-01-22 13:44:22 +00001445- To match the behaviour of HTTP server, the HTTP client library now also
1446 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1447 that for incoming headers which makes this behaviour now consistent in
1448 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001548- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001549 continuation line in the formatted value has no leading white space and looks
1550 like a header. Since Generator uses Header to format all headers, this check
1551 is made for all headers in any serialized message at serialization time. This
1552 provides protection against header injection attacks.

Éric Araujof0ab5d62011-05-29 03:43:59 +02001561 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001562 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001563
Éric Araujof0ab5d62011-05-29 03:43:59 +02001564- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001565 rfc2047-encoding header values with embedded newlines, leaving them without
1566 folding whitespace. It now uses the continuation_ws, as it does for
1567 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001569- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1570 time.asctime(), time.ctime() and time.strftime() functions will now format

1572 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1573 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1574 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002551- Issue #10068: Global objects which have reference cycles with their module's
2552 dict are now cleared again. This causes issue #7140 to appear again.
2553
Victor Stinner257d38f2010-10-09 10:12:11 +00002554- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00002557- ast.literal_eval() can now handle negative numbers. It is also a little more
2558 liberal in what it accepts without compromising the safety of the evaluation.
2559 For example, 3j+4 and 3+4+5 are both accepted.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002581- Issue #9930: Remove bogus subtype check that was causing (e.g.)

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002586- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2587 threads are still running. Instead, reinitialize the GIL on a second call to
2588 Py_Initialize().
2589
Georg Brandl27a28582010-10-10 09:49:21 +00002590- All SyntaxErrors now have a column offset and therefore a caret when the error
2591 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00002593- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2594 module that was imported, but instead gets the module from sys.modules.
2595
Nick Coghlan37ee8502010-12-03 14:26:13 +00002596- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002599- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2600 with a non-empty format string. This is an effort to future-proof user
2601 code. If a derived class does not currently implement __format__ but later
2602 adds its own __format__, it would most likely break user code that had
2603 supplied a format string. This will be changed to a DeprecationWaring in
2604 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002606- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2607 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2608 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2609
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002610- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2611 functions from the libc caused the methods .upper() and lower() to become
2612 locale aware and created subtly wrong results.
2613
Georg Brandl27a28582010-10-10 09:49:21 +00002614- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2615 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002616
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002617- Issue #4617: Previously it was illegal to delete a name from the local
2618 namespace if it occurs as a free variable in a nested block. This limitation
2619 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2620
Georg Brandl27a28582010-10-10 09:49:21 +00002621- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2622 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2623 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2624 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002625
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002626- Issue #9757: memoryview objects get a release() method to release the
2627 underlying buffer (previously this was only done when deallocating the
2628 memoryview), and gain support for the context management protocol.
2629
Antoine Pitrou079ce542010-09-08 12:37:10 +00002630- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2631 thread-local storage key.

2658
Éric Araujoef777bd2010-10-05 00:04:20 +00002659- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002660 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002661 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002662 replacement for old handle_accept() and avoids the user to call accept()
2663 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00002687 retry the select() loop instead of bailing out. This is because select() can

Antoine Pitrou98b46702010-09-18 22:59:00 +00002735- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00002736 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002769- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002770 it possible for the user to create self-referencing ordered dictionaries which
2771 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002772 approach of using weakref proxies so that reference cycles never get created
2773 in the first place.

2781 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2782 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002783
Georg Brandl27a28582010-10-10 09:49:21 +00002784- Issue #9410: Various optimizations to the pickle module, leading to speedups

2793
Georg Brandl27a28582010-10-10 09:49:21 +00002794- Issue #9707: Rewritten reference implementation of threading.local which is
2795 friendlier towards reference cycles. This change is not normally visible
2796 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002797
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002798- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2799 still return the id of the parent process after it has exited. This process
2800 id may even have been reused by another unrelated process.
2801
Georg Brandl27a28582010-10-10 09:49:21 +00002802- Issue #9792: In case of connection failure, socket.create_connection() would
2803 swallow the exception and raise a new one, making it impossible to fetch the
2804 original errno, or to filter timeout errors. Now the original error is
2805 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00002806
Georg Brandl27a28582010-10-10 09:49:21 +00002807- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2808 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2809 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00002810
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002811- Updates to the random module:
2812
Georg Brandl27a28582010-10-10 09:49:21 +00002813 * Document which parts of the module are guaranteed to stay the same across
2814 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002816 * Update the seed() method to use all of the bits in a string instead of just
2817 the hash value. This makes better use of the seed value and assures the
2818 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00002820 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2821 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2822 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002823
2824 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002843- hashlib has two new constant attributes: algorithms_guaranteed and
2844 algorithms_avaiable that respectively list the names of hash algorithms
2845 guaranteed to exist in all Python implementations and the names of hash
2846 algorithms available in the current process.
2847
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002848- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl62069d32010-07-31 08:56:11 +00003359 start byte and the continuation byte(s) are now considered invalid, instead of
3360 the number of bytes specified by the start byte. E.g.:

3437 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003438 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3439 (2) The comparison raised an OverflowError for large integers, leading to
3440 unpredictable exceptions when combining integers and complex objects in sets

3771 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3772 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003773 to match the behaviour of the other integer format codes.

3802 gives improved memory leak detection when running under Valgrind, while taking
3803 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003876- The default size of the re module's compiled regular expression cache has been
3877 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003878 simply clearing the entire cache on overflow to forgetting the least recently
3879 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003880 applications that use a lot of regular expressions and limits the impact of
3881 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003893- Issue #7989: Added pure python implementation of the `datetime` module. The C
3894 module is renamed to `_datetime` and if available, overrides all classes
3895 defined in datetime with fast C impementation. Python implementation is based
3896 on the original python prototype for the datetime module by Tim Peters with
3897 minor modifications by the PyPy project. The test suite now tests `datetime`
3898 module with and without `_datetime` acceleration using the same test cases.

4113 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
4114 file system encoding with the surrogateescape error handler (instead of
4115 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

Georg Brandl62069d32010-07-31 08:56:11 +00004135- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4136 operation raises multiple signals and more than one of those signals is
4137 trapped, the specification determines the order in which the signals should be
4138 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandl62069d32010-07-31 08:56:11 +00004178- Issue #8524: When creating an SSL socket, the timeout value of the original
4179 socket wasn't retained (instead, a socket with a positive timeout would be
4180 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004181
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004182- Issue #5103: SSL handshake would ignore the socket timeout and block

Georg Brandl62069d32010-07-31 08:56:11 +00004201- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4202 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004203 wanting to continue using the socket in clear-text mode, by disabling

Georg Brandl62069d32010-07-31 08:56:11 +00004295- Issue #2531: Comparison operations between floats and Decimal instances now
4296 return a result based on the numeric values of the operands; previously they
4297 returned an arbitrary result based on the relative ordering of id(float) and
4298 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4299 comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004642 default when instantiating a `threading.RLock` object. This makes recursive
4643 locks as fast as regular non-recursive locks (previously, they were slower by
4644 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00004797 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4798 PyPycLoader inherit from this class and provide implementations in relation to
4799 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004800
Brett Cannon64ef00f2009-07-20 03:19:18 +00004801- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4802 the documentation said it did even though the code in PyLoader relied on the
4803 abstract method required by ResourceLoader.
4804
Georg Brandl62069d32010-07-31 08:56:11 +00004805- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004853- Issue #9959: Tweak formula used for computing math.log of an integer,
4854 making it marginally more accurate for exact powers of 2.

Mark Dickinsoncf28b952010-07-29 21:41:59 +00004856- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
4857
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004858- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004859 compared to other unix systems. In particular, os.getgroups() does not reflect
4860 any changes made using os.setgroups() but basicly always returns the same
4861 information as the id command. os.getgroups() can now return more than 16
4862 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004863

Georg Brandl62069d32010-07-31 08:56:11 +00004887- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4888 Prior to this change, timezone adjustment in utctimetuple() could produce
4889 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4890 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00004891
Georg Brandl62069d32010-07-31 08:56:11 +00004892- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4893 directive. When the ``%z`` directive is present in the format string, an
4894 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4895 ``datetime.timezone`` instance constructed from the parsed offset. If both
4896 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4897 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004898
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004899- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004900 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4901 ``datetime.timezone``, return fixed name and UTC offset from their
4902 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4903 returns ``None``. A class attribute, ``utc`` contains an instance
4904 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004920- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4921 with an improved 'binary-split' algorithm that uses fewer multiplications and
4922 allows many of the multiplications to be performed using plain C integer
4923 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

4928
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004929- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4930 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004931 the result is now always correctly rounded, and is equivalent to ``td /
4932 timedelta(seconds=1)``.

4941 integer format code, struct.pack first attempts to convert the non-integer
4942 using its __index__ method. If that method is non-existent or raises
4943 TypeError it goes on to try the __int__ method, as described below.

5523 to be like 'g' but with at least one decimal point and with a
5524 default precision of 12. Previously, the behavior the same but with
5525 a default precision of 6. This more closely matches str(), and
5526 reduces surprises when adding alignment flags to the empty
5527 presentation type. This also affects the new complex.__format__ in
5528 the same way.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00005571- Issue #1869 (and many duplicates): make round(x, n) correctly
5572 rounded for a float x, by using the decimal <-> binary conversions
5573 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5574 consistently agrees with format(x, '.2f').
5575
Benjamin Petersonae937c02009-04-18 20:54:08 +00005576- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

5580
Eric Smith35e84722009-04-16 20:21:28 +00005581- Issue #5515: str.format() type 'n' combined with commas and leading
5582 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005583
5584- Implement PEP 378, Format Specifier for Thousands Separator, for
5585 floats.
5586
Mark Dickinson3370cce2009-04-17 22:40:53 +00005587- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005588 1e11, not 1e12. This avoids printing 13 significant digits in
5589 situations where only 12 of them are correct. Example problem
5590 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5591 long time.)
5592
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005593- Issue #1580: On most platforms, use a 'short' float repr: for a
5594 finite float x, repr(x) now outputs a string based on the shortest
5595 sequence of decimal digits that rounds to x. Previous behaviour was
5596 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005597 Another minor difference is that the new repr switches to
5598 exponential notation at 1e16 instead of the previous 1e17; this
5599 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005600
5601 There's a new sys attribute sys.float_repr_style, which takes
5602 the value 'short' to indicate that we're using short float repr,
5603 and 'legacy' if the short float repr isn't available for one
5604 reason or another.
5605
5606 The float repr change involves incorporating David Gay's 'perfect
5607 rounding' code into the Python core (it's in Python/dtoa.c). As a
5608 secondary consequence, all string-to-float and float-to-string
5609 conversions (including all float formatting operations) will be
5610 correctly rounded on these platforms.
5611
Georg Brandl5f90d792010-08-01 22:31:05 +00005612 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005613 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005615- Issue #5759: float() didn't call __float__ on str subclasses.
5616
Georg Brandlabc38772009-04-12 15:51:51 +00005617- The string.maketrans() function is deprecated; there is a new static method
5618 maketrans() on the bytes and bytearray classes. This removes confusion about
5619 the types string.maketrans() is supposed to work with, and mirrors the
5620 methods available on the str class.
5621
R. David Murraydc6da8a2009-04-09 22:16:43 +00005622- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5789 untrackable objects are not tracked by the garbage collector. This can
5790 reduce the size of collections and therefore the garbage collection overhead
5791 on long-running programs, depending on their particular use of datatypes.

5856 (typically /dev/zero under Unix) could crash the interpreter.
5857
Benjamin Peterson59406a92009-03-26 17:10:29 +00005858- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

5860
Lars Gustäbel42e00912009-03-22 20:34:29 +00005861- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5862 forever on incomplete input. That caused tarfile.open() to hang when used
5863 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5864 partial bzip2 compressed data.
5865
Mark Dickinson79f52032009-03-17 23:12:51 +00005866- Issue #2110: Add support for thousands separator and 'n' type

5870 '>' alignment characters.
5871
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005872- The error detection code in FileIO.close() could fail to reflect the `errno`

5884 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005885 struct.error instead of returning b'\xff\xff\xff\xff'. The
5886 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5887 have been removed from the struct module.

5903 used when using str.format() with str, int, and float arguments.
5904
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005905- Issue #5249: time.strftime returned malformed string when format string
5906 contained non ascii character on windows.
5907
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005908- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5909 source has already been decoded into str.
5910
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005911- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5912 rotating the object pointer by 4 bits to the right.
5913
Mark Dickinson87ec0852009-02-09 17:15:59 +00005914- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5915 it now forces its argument to double before testing for infinity.
5916
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005917- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5918 returns a non-number type.
5919
Benjamin Peterson87618552009-02-08 15:00:52 +00005920- Issue #5182: Removed memoryview.__str__.
5921
Mark Dickinsonc008a172009-02-01 13:59:22 +00005922- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5923 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005924 the type definition cmpfunc. The tp_compare slot has been renamed
5925 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005926
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005927- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005928 were suppressing all exceptions. These include list() and bytearray().
5929
Mark Dickinson1124e712009-01-28 21:25:58 +00005930- Issue #4707: round(x, n) now returns an integer if x is an integer.
5931 Previously it returned a float.
5932
Antoine Pitroub52ec782009-01-25 16:34:23 +00005933- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5934 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5935 evaluation loop is compiled with a new dispatch mechanism which gives
5936 speedups of up to 20%, depending on the system, on various benchmarks.
5937
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005938- Issue #4874: Most builtin decoders now reject unicode input.

5944
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005945- Issue #4838: When a module is deallocated, free the memory backing the
5946 optional module state data.
5947
Mark Dickinson8055afd2009-01-17 10:04:45 +00005948- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005949 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005950
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005951- Issue #4935: The overflow checking code in the expandtabs() method common
5952 to str, bytes and bytearray could be optimized away by the compiler, letting
5953 the interpreter segfault instead of raising an error.
5954
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005955- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5956 __next__ method.
5957
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005958- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5959 function no longer attempt to call the __long__ slot to convert an object
5960 to an integer. Only the __int__ and __trunc__ slots are examined.
5961
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005962- Issue #4893: Use NT threading on CE.
5963
Martin v. Löwisec59d042009-01-12 07:59:10 +00005964- Issue #4915: Port sysmodule to Windows CE.
5965
Antoine Pitrouab868312009-01-10 15:40:25 +00005966- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5967 common cases are optimized thanks to a dedicated fast path and a moderate
5968 amount of loop unrolling.
5969
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005970- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5971 collecting the oldest generation) so that allocating lots of objects without
5972 destroying them does not show quadratic performance. Based on a proposal by
5973 Martin von Löwis at
5974 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5975
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005976- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005977 having been closed (for instance, a read() call could return some
5978 previously buffered data). Patch by Dmitry Vasiliev.
5979
Antoine Pitrou05608432009-01-09 18:53:14 +00005980- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5981 flag to work properly. Furthermore, when specifying -u, the text stdout
5982 and stderr streams have line-by-line buffering enabled (the default being
5983 to buffer arbitrary chunks of data).
5984
Raymond Hettinger35631532009-01-09 03:58:09 +00005985- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5986 instead of ints (reducing its size from 4 to 8 times thereby reducing
5987 Python's overall memory).
5988
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005989- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5990 an existing .py counterpart, override the co_filename attributes of all
5991 code objects if the original filename is obsolete (which can happen if the
5992 file has been renamed, moved, or if it is accessed through different paths).
5993 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5994
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005995- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5996 one byte. Also fixes the meaning of len() so that it returns the number of
5997 items, rather than the size in bytes.
5998
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005999- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6000
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006001- Issue #4747: When the terminal does not use utf-8, executing a script with
6002 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6003
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006004- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6005 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006006
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006007- Issue #3680: Reference cycles created through a dict, set or deque iterator
6008 did not get collected.
6009
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006010- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6011 where the tp_hash and tp_dict slots are both NULL.
6012
Georg Brandlccc47b62008-12-28 11:44:14 +00006013- Issue #4759: None is now allowed as the first argument of
6014 bytearray.translate(). It was always allowed for bytes.translate().
6015
Skip Montanaro80072cb2008-12-23 03:51:14 +00006016- Added test case to ensure attempts to read from a file opened for writing
6017 fail.
6018
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006019- Issue #3106: Speedup some comparisons (str/str and int/int).

6023
Antoine Pitrou621601a2008-12-17 23:18:19 +00006024- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6025 print elapsed times, not only when some objects are uncollectable /
6026 unreachable. Original patch by Neil Schemenauer.
6027
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006028- Issue #3439: Add a bit_length method to int.
6029
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006030- Issue #2173: When getting device encoding, check that return value of
6031 nl_langinfo is not the empty string. This was causing silent build
6032 failures on OS X.
6033
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006034- Issue #4597: Fixed several opcodes that weren't always propagating
6035 exceptions.
6036
6037- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006038 context manager returns a value that cannot be converted to a bool.
6039
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006040- Issue #4445: Replace "sizeof(PyBytesObject)" with
6041 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6042 bytes instances. On a typical machine this saves 3 bytes of memory
6043 (on average) per allocation of a bytes instance.
6044
Christian Heimesa872de52008-12-05 08:26:55 +00006045- Issue #4533: File read operation was dreadfully slow due to a slowly
6046 growing read buffer. Fixed by using the same growth rate algorithm as
6047 Python 2.x.
6048
Antoine Pitrou5504e892008-12-06 21:27:53 +00006049- Issue #4509: Various issues surrounding resize of bytearray objects to
6050 which there are buffer exports (e.g. memoryview instances).
6051
Georg Brandlf9734072008-12-07 15:30:06 +00006052- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6053 method on file objects with closefd=False. The file descriptor is still
6054 kept open but the file object behaves like a closed file. The ``FileIO``
6055 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006056
Antoine Pitroubc420402008-12-07 20:14:49 +00006057- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6058 larger than 1.

6063
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006064- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6065 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6066 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6067 of using the replace error handler in PyUnicode_DecodeUTF8().
