Victor Stinner4ee65a92011-01-22 10:30:29 +0000588 filenames, at bootstrap, if the codec registry is not ready yet. It is still
589 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000590 for all file entries in the ZIP file.

599
Armin Ronacher8d96d772011-01-22 13:13:05 +0000600- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
601 encoding. This is the preferred encoding of PEP 3333 and the base encoding
602 of HTTP 1.1.
603
Armin Ronacher59531282011-01-22 13:44:22 +0000604- To match the behaviour of HTTP server, the HTTP client library now also
605 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
606 that for incoming headers which makes this behaviour now consistent in
607 both incoming and outgoing direction.

Georg Brandl255abdd2011-01-16 14:17:26 +0000698 continuation line in the formatted value has no leading white space and looks
699 like a header. Since Generator uses Header to format all headers, this check
700 is made for all headers in any serialized message at serialization time. This
701 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000702
Antoine Pitrou67b212e2011-01-08 09:55:31 +0000703- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

R. David Murray92532142011-01-07 23:25:30 +0000709- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
Georg Brandl255abdd2011-01-16 14:17:26 +0000710 non-ASCII bytes (parsed by a Bytes Parser) when doing conversion to 7bit-clean
711 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +0000712
R. David Murray6f0022d2011-01-07 21:57:25 +0000713- email.header.Header was incorrectly encoding folding white space when
Georg Brandl255abdd2011-01-16 14:17:26 +0000714 rfc2047-encoding header values with embedded newlines, leaving them without
715 folding whitespace. It now uses the continuation_ws, as it does for
716 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +0000718- Issue #1777412, #10827: Changed the rules for 2-digit years. The
719 time.asctime(), time.ctime() and time.strftime() functions will now format
720 any year when ``time.accept2dyear`` is False and will accept years >= 1000
721 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
722 supported by the OS. With Visual Studio or on Solaris, the year is limited to
723 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl27a28582010-10-10 09:49:21 +00001704- ast.literal_eval() can now handle negative numbers. It is also a little more
1705 liberal in what it accepts without compromising the safety of the evaluation.
1706 For example, 3j+4 and 3+4+5 are both accepted.

Victor Stinner5593d8a2010-10-02 11:11:27 +00001713- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001714 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001728- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001729 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

1732
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001733- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1734 threads are still running. Instead, reinitialize the GIL on a second call to
1735 Py_Initialize().
1736
Georg Brandl27a28582010-10-10 09:49:21 +00001737- All SyntaxErrors now have a column offset and therefore a caret when the error
1738 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001739
Brett Cannonbc2eff32010-09-19 21:39:02 +00001740- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1741 module that was imported, but instead gets the module from sys.modules.
1742
Nick Coghlan37ee8502010-12-03 14:26:13 +00001743- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001744 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.

Georg Brandl27a28582010-10-10 09:49:21 +00001746- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1747 with a non-empty format string. This is an effort to future-proof user
1748 code. If a derived class does not currently implement __format__ but later
1749 adds its own __format__, it would most likely break user code that had
1750 supplied a format string. This will be changed to a DeprecationWaring in
1751 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001752
Antoine Pitrou1df15362010-09-13 14:16:46 +00001753- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1754 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1755 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1756
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001757- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1758 functions from the libc caused the methods .upper() and lower() to become
1759 locale aware and created subtly wrong results.
1760
Georg Brandl27a28582010-10-10 09:49:21 +00001761- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1762 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001763
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001764- Issue #4617: Previously it was illegal to delete a name from the local
1765 namespace if it occurs as a free variable in a nested block. This limitation
1766 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1767
Georg Brandl27a28582010-10-10 09:49:21 +00001768- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1769 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1770 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1771 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001772
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001773- Issue #9757: memoryview objects get a release() method to release the
1774 underlying buffer (previously this was only done when deallocating the
1775 memoryview), and gain support for the context management protocol.
1776
Antoine Pitrou079ce542010-09-08 12:37:10 +00001777- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1778 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00001794- Issue #4661: email can now parse bytes input and generate either converted

1796
Antoine Pitrou59fdd672010-10-08 10:37:08 +00001797- Issue #1589: Add ssl.match_hostname(), to help implement server identity

1805
Éric Araujoef777bd2010-10-05 00:04:20 +00001806- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001807 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001808 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001809 replacement for old handle_accept() and avoids the user to call accept()
1810 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00001834 retry the select() loop instead of bailing out. This is because select() can
1835 incorrectly report a socket as ready for reading (for example, if it received
1836 some data with an invalid checksum).

1881
Antoine Pitrou98b46702010-09-18 22:59:00 +00001882- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00001883 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00001916- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001917 it possible for the user to create self-referencing ordered dictionaries which
1918 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001919 approach of using weakref proxies so that reference cycles never get created
1920 in the first place.

1928 sys.setfilesystemencoding() creates inconsistencies because it is unable to
1929 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00001930

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001945- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1946 still return the id of the parent process after it has exited. This process
1947 id may even have been reused by another unrelated process.
1948
Georg Brandl27a28582010-10-10 09:49:21 +00001949- Issue #9792: In case of connection failure, socket.create_connection() would

1952 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00001953
Georg Brandl27a28582010-10-10 09:49:21 +00001954- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
1955 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
1956 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00001957
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001958- Updates to the random module:
1959
Georg Brandl27a28582010-10-10 09:49:21 +00001960 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00001963 * Update the seed() method to use all of the bits in a string instead of just

Georg Brandl27a28582010-10-10 09:49:21 +00001967 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1968 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1969 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001970
1971 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00001990- hashlib has two new constant attributes: algorithms_guaranteed and
1991 algorithms_avaiable that respectively list the names of hash algorithms
1992 guaranteed to exist in all Python implementations and the names of hash
1993 algorithms available in the current process.
1994

Georg Brandl62069d32010-07-31 08:56:11 +00002506 start byte and the continuation byte(s) are now considered invalid, instead of
2507 the number of bytes specified by the start byte. E.g.:

2509 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2510 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2511 returned a single u'\ufffd'.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00002583- Issue #8748: Fix two issues with comparisons between complex and integer
2584 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002585 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2586 (2) The comparison raised an OverflowError for large integers, leading to
2587 unpredictable exceptions when combining integers and complex objects in sets
2588 or dicts.

2918 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
2919 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00002920 to match the behaviour of the other integer format codes.

2949 gives improved memory leak detection when running under Valgrind, while taking
2950 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003023- The default size of the re module's compiled regular expression cache has been
3024 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003025 simply clearing the entire cache on overflow to forgetting the least recently
3026 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003027 applications that use a lot of regular expressions and limits the impact of
3028 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003040- Issue #7989: Added pure python implementation of the `datetime` module. The C
3041 module is renamed to `_datetime` and if available, overrides all classes
3042 defined in datetime with fast C impementation. Python implementation is based
3043 on the original python prototype for the datetime module by Tim Peters with
3044 minor modifications by the PyPy project. The test suite now tests `datetime`
3045 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00003282- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3283 operation raises multiple signals and more than one of those signals is
3284 trapped, the specification determines the order in which the signals should be
3285 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandl62069d32010-07-31 08:56:11 +00003442- Issue #2531: Comparison operations between floats and Decimal instances now
3443 return a result based on the numeric values of the operands; previously they
3444 returned an arbitrary result based on the relative ordering of id(float) and

Georg Brandl62069d32010-07-31 08:56:11 +00003789 default when instantiating a `threading.RLock` object. This makes recursive
3790 locks as fast as regular non-recursive locks (previously, they were slower by
3791 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00003944 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
3945 PyPycLoader inherit from this class and provide implementations in relation to
3946 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00003947
Brett Cannon64ef00f2009-07-20 03:19:18 +00003948- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
3949 the documentation said it did even though the code in PyLoader relied on the
3950 abstract method required by ResourceLoader.

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004000- Issue #9959: Tweak formula used for computing math.log of an integer,
4001 making it marginally more accurate for exact powers of 2.
4002
Mark Dickinsoncf28b952010-07-29 21:41:59 +00004003- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
4004
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004005- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004006 compared to other unix systems. In particular, os.getgroups() does not reflect
4007 any changes made using os.setgroups() but basicly always returns the same
4008 information as the id command. os.getgroups() can now return more than 16
4009 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004010

Georg Brandl62069d32010-07-31 08:56:11 +00004034- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4035 Prior to this change, timezone adjustment in utctimetuple() could produce
4036 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4037 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004039- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4040 directive. When the ``%z`` directive is present in the format string, an
4041 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4042 ``datetime.timezone`` instance constructed from the parsed offset. If both
4043 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4044 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004046- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004047 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4048 ``datetime.timezone``, return fixed name and UTC offset from their
4049 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4050 returns ``None``. A class attribute, ``utc`` contains an instance
4051 representing the UTC timezone. Original patch by Rafe Kaplan.

Georg Brandl62069d32010-07-31 08:56:11 +00004067- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4068 with an improved 'binary-split' algorithm that uses fewer multiplications and
4069 allows many of the multiplications to be performed using plain C integer
4070 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00004076- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4077 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004078 the result is now always correctly rounded, and is equivalent to ``td /
4079 timedelta(seconds=1)``.

4088 integer format code, struct.pack first attempts to convert the non-integer
4089 using its __index__ method. If that method is non-existent or raises
4090 TypeError it goes on to try the __int__ method, as described below.

4365 threads could return successfully while some Thread objects were still
4366 referenced. This also introduces a new private function:

Georg Brandl62069d32010-07-31 08:56:11 +00004376 runtest_inner in regrtest, with warnings if the called test modifies them, and

4671 default precision of 12. Previously, the behavior the same but with
4672 a default precision of 6. This more closely matches str(), and
4673 reduces surprises when adding alignment flags to the empty
4674 presentation type. This also affects the new complex.__format__ in
4675 the same way.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00004718- Issue #1869 (and many duplicates): make round(x, n) correctly
4719 rounded for a float x, by using the decimal <-> binary conversions
4720 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4721 consistently agrees with format(x, '.2f').
4722
Benjamin Petersonae937c02009-04-18 20:54:08 +00004723- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

4727
Eric Smith35e84722009-04-16 20:21:28 +00004728- Issue #5515: str.format() type 'n' combined with commas and leading
4729 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004730
4731- Implement PEP 378, Format Specifier for Thousands Separator, for
4732 floats.
4733
Mark Dickinson3370cce2009-04-17 22:40:53 +00004734- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004735 1e11, not 1e12. This avoids printing 13 significant digits in
4736 situations where only 12 of them are correct. Example problem
4737 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4738 long time.)
4739
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004740- Issue #1580: On most platforms, use a 'short' float repr: for a
4741 finite float x, repr(x) now outputs a string based on the shortest
4742 sequence of decimal digits that rounds to x. Previous behaviour was
4743 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004744 Another minor difference is that the new repr switches to
4745 exponential notation at 1e16 instead of the previous 1e17; this
4746 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004747
4748 There's a new sys attribute sys.float_repr_style, which takes
4749 the value 'short' to indicate that we're using short float repr,
4750 and 'legacy' if the short float repr isn't available for one
4751 reason or another.
4752
4753 The float repr change involves incorporating David Gay's 'perfect
4754 rounding' code into the Python core (it's in Python/dtoa.c). As a
4755 secondary consequence, all string-to-float and float-to-string
4756 conversions (including all float formatting operations) will be
4757 correctly rounded on these platforms.
4758
Georg Brandl5f90d792010-08-01 22:31:05 +00004759 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004760 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004762- Issue #5759: float() didn't call __float__ on str subclasses.
4763
Georg Brandlabc38772009-04-12 15:51:51 +00004764- The string.maketrans() function is deprecated; there is a new static method
4765 maketrans() on the bytes and bytearray classes. This removes confusion about
4766 the types string.maketrans() is supposed to work with, and mirrors the
4767 methods available on the str class.

R. David Murraydc6da8a2009-04-09 22:16:43 +00004769- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

5003 (typically /dev/zero under Unix) could crash the interpreter.
5004
Benjamin Peterson59406a92009-03-26 17:10:29 +00005005- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

5007
Lars Gustäbel42e00912009-03-22 20:34:29 +00005008- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5009 forever on incomplete input. That caused tarfile.open() to hang when used
5010 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5011 partial bzip2 compressed data.
5012
Mark Dickinson79f52032009-03-17 23:12:51 +00005013- Issue #2110: Add support for thousands separator and 'n' type

5017 '>' alignment characters.
5018
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00005019- The error detection code in FileIO.close() could fail to reflect the `errno`
5020 value, and report it as -1 instead.
5021
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00005022- Issue #5016: FileIO.seekable() could return False if the file position

5031 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00005032 struct.error instead of returning b'\xff\xff\xff\xff'. The
5033 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
5034 have been removed from the struct module.

5048
Eric Smith5e5c0db2009-02-20 14:25:03 +00005049- Issue #5247: Improve error message when unknown format codes are
5050 used when using str.format() with str, int, and float arguments.
5051
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00005052- Issue #5249: time.strftime returned malformed string when format string
5053 contained non ascii character on windows.
5054
Benjamin Petersonf5b52242009-03-02 23:31:26 +00005055- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
5056 source has already been decoded into str.
5057
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00005058- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5059 rotating the object pointer by 4 bits to the right.
5060
Mark Dickinson87ec0852009-02-09 17:15:59 +00005061- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5062 it now forces its argument to double before testing for infinity.
5063
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005064- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5065 returns a non-number type.
5066
Benjamin Peterson87618552009-02-08 15:00:52 +00005067- Issue #5182: Removed memoryview.__str__.
5068
Mark Dickinsonc008a172009-02-01 13:59:22 +00005069- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5070 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00005071 the type definition cmpfunc. The tp_compare slot has been renamed
5072 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005073
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005074- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005075 were suppressing all exceptions. These include list() and bytearray().
5076
Mark Dickinson1124e712009-01-28 21:25:58 +00005077- Issue #4707: round(x, n) now returns an integer if x is an integer.
5078 Previously it returned a float.
5079
Antoine Pitroub52ec782009-01-25 16:34:23 +00005080- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5081 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5082 evaluation loop is compiled with a new dispatch mechanism which gives
5083 speedups of up to 20%, depending on the system, on various benchmarks.
5084
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005085- Issue #4874: Most builtin decoders now reject unicode input.

5091
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005092- Issue #4838: When a module is deallocated, free the memory backing the
5093 optional module state data.
5094
Mark Dickinson8055afd2009-01-17 10:04:45 +00005095- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005096 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005097
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005098- Issue #4935: The overflow checking code in the expandtabs() method common
5099 to str, bytes and bytearray could be optimized away by the compiler, letting
5100 the interpreter segfault instead of raising an error.
5101
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005102- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5103 __next__ method.
5104
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005105- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5106 function no longer attempt to call the __long__ slot to convert an object
5107 to an integer. Only the __int__ and __trunc__ slots are examined.
5108
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005109- Issue #4893: Use NT threading on CE.
5110
Martin v. Löwisec59d042009-01-12 07:59:10 +00005111- Issue #4915: Port sysmodule to Windows CE.
5112
Antoine Pitrouab868312009-01-10 15:40:25 +00005113- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5114 common cases are optimized thanks to a dedicated fast path and a moderate
5115 amount of loop unrolling.
5116
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005117- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5118 collecting the oldest generation) so that allocating lots of objects without
5119 destroying them does not show quadratic performance. Based on a proposal by
5120 Martin von Löwis at
5121 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5122
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005123- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005124 having been closed (for instance, a read() call could return some
5125 previously buffered data). Patch by Dmitry Vasiliev.
5126
Antoine Pitrou05608432009-01-09 18:53:14 +00005127- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5128 flag to work properly. Furthermore, when specifying -u, the text stdout
5129 and stderr streams have line-by-line buffering enabled (the default being
5130 to buffer arbitrary chunks of data).
5131
Raymond Hettinger35631532009-01-09 03:58:09 +00005132- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5133 instead of ints (reducing its size from 4 to 8 times thereby reducing
5134 Python's overall memory).
5135
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005136- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5137 an existing .py counterpart, override the co_filename attributes of all
5138 code objects if the original filename is obsolete (which can happen if the
5139 file has been renamed, moved, or if it is accessed through different paths).
5140 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5141
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005142- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5143 one byte. Also fixes the meaning of len() so that it returns the number of
5144 items, rather than the size in bytes.
5145
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005146- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5147
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005148- Issue #4747: When the terminal does not use utf-8, executing a script with
5149 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5150
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005151- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5152 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005153
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005154- Issue #3680: Reference cycles created through a dict, set or deque iterator
5155 did not get collected.
5156
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005157- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5158 where the tp_hash and tp_dict slots are both NULL.
5159
Georg Brandlccc47b62008-12-28 11:44:14 +00005160- Issue #4759: None is now allowed as the first argument of
5161 bytearray.translate(). It was always allowed for bytes.translate().
5162
Skip Montanaro80072cb2008-12-23 03:51:14 +00005163- Added test case to ensure attempts to read from a file opened for writing
5164 fail.
5165
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005166- Issue #3106: Speedup some comparisons (str/str and int/int).

5170
Antoine Pitrou621601a2008-12-17 23:18:19 +00005171- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5172 print elapsed times, not only when some objects are uncollectable /
5173 unreachable. Original patch by Neil Schemenauer.
5174
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005175- Issue #3439: Add a bit_length method to int.
5176
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005177- Issue #2173: When getting device encoding, check that return value of
5178 nl_langinfo is not the empty string. This was causing silent build
5179 failures on OS X.
5180
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005181- Issue #4597: Fixed several opcodes that weren't always propagating
5182 exceptions.
5183
5184- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005185 context manager returns a value that cannot be converted to a bool.
5186
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005187- Issue #4445: Replace "sizeof(PyBytesObject)" with
5188 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5189 bytes instances. On a typical machine this saves 3 bytes of memory
5190 (on average) per allocation of a bytes instance.
5191
Christian Heimesa872de52008-12-05 08:26:55 +00005192- Issue #4533: File read operation was dreadfully slow due to a slowly
5193 growing read buffer. Fixed by using the same growth rate algorithm as
5194 Python 2.x.
5195
Antoine Pitrou5504e892008-12-06 21:27:53 +00005196- Issue #4509: Various issues surrounding resize of bytearray objects to
5197 which there are buffer exports (e.g. memoryview instances).
5198
Georg Brandlf9734072008-12-07 15:30:06 +00005199- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5200 method on file objects with closefd=False. The file descriptor is still
5201 kept open but the file object behaves like a closed file. The ``FileIO``
5202 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005203
Antoine Pitroubc420402008-12-07 20:14:49 +00005204- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5205 larger than 1.

5210
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005211- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5212 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5213 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5214 of using the replace error handler in PyUnicode_DecodeUTF8().
