Antoine Pitrou5136ac02012-01-13 18:52:16 +010016- Issue #13645: pyc files now contain the size of the corresponding source
17 code, to avoid timestamp collisions (especially on filesystems with a low
18 timestamp resolution) when checking for freshness of the bytecode.
19
Nick Coghlan1f7ce622012-01-13 21:43:40 +100020- PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to
21 subgenerators (initial patch by Greg Ewing, integration into 3.3 by
22 Renaud Blanch, Ryan Kelly, Zbigniew Jędrzejewski-Szmek and Nick Coghlan)
23

37 objects. Initial patch by Matthias Troffaes.
38
Antoine Pitroue0e27352011-12-15 14:31:28 +010039- Fix OSError.__init__ and OSError.__new__ so that each of them can be
40 overriden and take additional arguments (followup to issue #12555).
41
Antoine Pitrou2e872082011-12-15 14:15:31 +010042- Fix the fix for issue #12149: it was incorrect, although it had the side
43 effect of appearing to resolve the issue. Thanks to Mark Shannon for
44 noticing.

Victor Stinner6345be92011-11-25 20:09:01 +010065 different than "strict" anymore. The caller was unable to compute the
66 size of the output buffer: it depends on the error handler.
67
Antoine Pitrou86a36b52011-11-25 18:56:07 +010068- PEP 3155 / issue #13448: Qualified name for classes and functions.

82
Antoine Pitrou56a220a2011-11-16 00:56:10 +010083- Issue #13393: BufferedReader.read1() now asks the full requested size to
84 the raw stream instead of limiting itself to the buffer size.
85
Antoine Pitrou28e401e2011-11-15 19:15:19 +010086- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
87
Antoine Pitrou5418ee02011-11-15 01:42:21 +010088- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
89 already accepts them).
90
Antoine Pitrou9a812cb2011-11-15 00:00:12 +010091- Issue #13389: Full garbage collection passes now clear the freelists for
92 list and dict objects. They already cleared other freelists in the
93 interpreter.
94
Brian Curtin52fbea12011-11-06 13:41:17 -060095- Issue #13327: Remove the need for an explicit None as the second argument

97 order to update to the current time. Also added keyword argument
98 handling to os.utimensat in order to remove the need for explicit None.

125 object identity).
126
Nick Coghlande31b192011-10-23 22:04:16 +1000127- Issue #1294232: In a few cases involving metaclass inheritance, the

Ned Deily657b2de2011-06-28 19:51:30 -07001059- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1060 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1061 interpreter process. This could cause failures in non-Distutils subprocesses
1062 and was unreliable since tests or user programs could modify the interpreter
1063 environment after Distutils set it. Instead, have Distutils set the the
1064 deployment target only in the environment of each build subprocess. It is
1065 still possible to globally override the default by setting
1066 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1067 greater or equal to the default value, the value with which the interpreter

R. David Murray5b2d9dd2011-01-09 02:35:24 +00002318- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00002319 continuation line in the formatted value has no leading white space and looks
2320 like a header. Since Generator uses Header to format all headers, this check
2321 is made for all headers in any serialized message at serialization time. This
2322 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00002323

Georg Brandl255abdd2011-01-16 14:17:26 +00002332 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002333
Éric Araujof0ab5d62011-05-29 03:43:59 +02002334- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00002335 rfc2047-encoding header values with embedded newlines, leaving them without
2336 folding whitespace. It now uses the continuation_ws, as it does for
2337 continuation lines that it creates itself.

2340 time.asctime(), time.ctime() and time.strftime() functions will now format

2342 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2343 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2344 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002978 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00003325- Issue #10068: Global objects which have reference cycles with their module's
3326 dict are now cleared again. This causes issue #7140 to appear again.
3327
Victor Stinner257d38f2010-10-09 10:12:11 +00003328- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()

Georg Brandl27a28582010-10-10 09:49:21 +00003331- ast.literal_eval() can now handle negative numbers. It is also a little more
3332 liberal in what it accepts without compromising the safety of the evaluation.
3333 For example, 3j+4 and 3+4+5 are both accepted.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003355- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00003356 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003360- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3361 threads are still running. Instead, reinitialize the GIL on a second call to
3362 Py_Initialize().
3363
Georg Brandl27a28582010-10-10 09:49:21 +00003364- All SyntaxErrors now have a column offset and therefore a caret when the error
3365 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00003366
Brett Cannonbc2eff32010-09-19 21:39:02 +00003367- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3368 module that was imported, but instead gets the module from sys.modules.
3369
Nick Coghlan37ee8502010-12-03 14:26:13 +00003370- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00003373- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3374 with a non-empty format string. This is an effort to future-proof user
3375 code. If a derived class does not currently implement __format__ but later
3376 adds its own __format__, it would most likely break user code that had
3377 supplied a format string. This will be changed to a DeprecationWaring in
3378 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003379
Antoine Pitrou1df15362010-09-13 14:16:46 +00003380- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3381 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3382 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3383
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003384- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3385 functions from the libc caused the methods .upper() and lower() to become
3386 locale aware and created subtly wrong results.
3387
Georg Brandl27a28582010-10-10 09:49:21 +00003388- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3389 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003390
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003391- Issue #4617: Previously it was illegal to delete a name from the local
3392 namespace if it occurs as a free variable in a nested block. This limitation
3393 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3394
Georg Brandl27a28582010-10-10 09:49:21 +00003395- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3396 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3397 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3398 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003399
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003400- Issue #9757: memoryview objects get a release() method to release the
3401 underlying buffer (previously this was only done when deallocating the
3402 memoryview), and gain support for the context management protocol.
3403
Antoine Pitrou079ce542010-09-08 12:37:10 +00003404- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3405 thread-local storage key.

3432
Éric Araujoef777bd2010-10-05 00:04:20 +00003433- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003434 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003435 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003436 replacement for old handle_accept() and avoids the user to call accept()
3437 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00003461 retry the select() loop instead of bailing out. This is because select() can
3462 incorrectly report a socket as ready for reading (for example, if it received

Georg Brandl27a28582010-10-10 09:49:21 +00003510 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003543- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003544 it possible for the user to create self-referencing ordered dictionaries which
3545 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003546 approach of using weakref proxies so that reference cycles never get created
3547 in the first place.

3555 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3556 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00003557

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003572- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3573 still return the id of the parent process after it has exited. This process
3574 id may even have been reused by another unrelated process.
3575
Georg Brandl27a28582010-10-10 09:49:21 +00003576- Issue #9792: In case of connection failure, socket.create_connection() would
3577 swallow the exception and raise a new one, making it impossible to fetch the
3578 original errno, or to filter timeout errors. Now the original error is
3579 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003581- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3582 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3583 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00003584
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003585- Updates to the random module:
3586
Georg Brandl27a28582010-10-10 09:49:21 +00003587 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003594 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3595 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3596 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003597
3598 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003617- hashlib has two new constant attributes: algorithms_guaranteed and
3618 algorithms_avaiable that respectively list the names of hash algorithms
3619 guaranteed to exist in all Python implementations and the names of hash
3620 algorithms available in the current process.

Ezio Melotti57221d02010-07-01 07:32:02 +00004132- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00004133 start byte and the continuation byte(s) are now considered invalid, instead of
4134 the number of bytes specified by the start byte. E.g.:
4135 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4136 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4137 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4138 returned a single u'\ufffd'.

4182 TypeError instead of giving a DeprecationWarning when a float is parsed using
4183 the 'L' code (for long long). (All other integer codes already raise

4545 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4546 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004547 to match the behaviour of the other integer format codes.

4576 gives improved memory leak detection when running under Valgrind, while taking
4577 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00004650- The default size of the re module's compiled regular expression cache has been
4651 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004652 simply clearing the entire cache on overflow to forgetting the least recently
4653 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004654 applications that use a lot of regular expressions and limits the impact of
4655 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004909- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4910 operation raises multiple signals and more than one of those signals is
4911 trapped, the specification determines the order in which the signals should be
4912 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandl62069d32010-07-31 08:56:11 +00005069- Issue #2531: Comparison operations between floats and Decimal instances now
5070 return a result based on the numeric values of the operands; previously they

Georg Brandl62069d32010-07-31 08:56:11 +00005416 default when instantiating a `threading.RLock` object. This makes recursive
5417 locks as fast as regular non-recursive locks (previously, they were slower by
5418 10x to 15x).

Georg Brandl62069d32010-07-31 08:56:11 +00005571 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
5572 PyPycLoader inherit from this class and provide implementations in relation to
5573 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00005574
Brett Cannon64ef00f2009-07-20 03:19:18 +00005575- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
5576 the documentation said it did even though the code in PyLoader relied on the
5577 abstract method required by ResourceLoader.

5631
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005632- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005633 compared to other unix systems. In particular, os.getgroups() does not reflect
5634 any changes made using os.setgroups() but basicly always returns the same
5635 information as the id command. os.getgroups() can now return more than 16
5636 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005637

Georg Brandl62069d32010-07-31 08:56:11 +00005661- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5662 Prior to this change, timezone adjustment in utctimetuple() could produce
5663 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5664 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00005666- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5667 directive. When the ``%z`` directive is present in the format string, an
5668 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5669 ``datetime.timezone`` instance constructed from the parsed offset. If both
5670 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5671 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005674 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5675 ``datetime.timezone``, return fixed name and UTC offset from their
5676 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5677 returns ``None``. A class attribute, ``utc`` contains an instance
5678 representing the UTC timezone. Original patch by Rafe Kaplan.

5695 with an improved 'binary-split' algorithm that uses fewer multiplications and
5696 allows many of the multiplications to be performed using plain C integer
5697 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

5704 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005705 the result is now always correctly rounded, and is equivalent to ``td /
5706 timedelta(seconds=1)``.

5715 integer format code, struct.pack first attempts to convert the non-integer
5716 using its __index__ method. If that method is non-existent or raises
5717 TypeError it goes on to try the __int__ method, as described below.

6298 default precision of 12. Previously, the behavior the same but with
6299 a default precision of 6. This more closely matches str(), and
6300 reduces surprises when adding alignment flags to the empty

6342
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006343- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00006345- Issue #1869 (and many duplicates): make round(x, n) correctly
6346 rounded for a float x, by using the decimal <-> binary conversions
6347 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6348 consistently agrees with format(x, '.2f').
6349
Benjamin Petersonae937c02009-04-18 20:54:08 +00006350- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

6354
Eric Smith35e84722009-04-16 20:21:28 +00006355- Issue #5515: str.format() type 'n' combined with commas and leading
6356 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006357
6358- Implement PEP 378, Format Specifier for Thousands Separator, for
6359 floats.
6360
Mark Dickinson3370cce2009-04-17 22:40:53 +00006361- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006362 1e11, not 1e12. This avoids printing 13 significant digits in
6363 situations where only 12 of them are correct. Example problem
6364 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6365 long time.)
6366
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006367- Issue #1580: On most platforms, use a 'short' float repr: for a
6368 finite float x, repr(x) now outputs a string based on the shortest
6369 sequence of decimal digits that rounds to x. Previous behaviour was
6370 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006371 Another minor difference is that the new repr switches to
6372 exponential notation at 1e16 instead of the previous 1e17; this
6373 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006374
6375 There's a new sys attribute sys.float_repr_style, which takes
6376 the value 'short' to indicate that we're using short float repr,
6377 and 'legacy' if the short float repr isn't available for one
6378 reason or another.
6379
6380 The float repr change involves incorporating David Gay's 'perfect
6381 rounding' code into the Python core (it's in Python/dtoa.c). As a
6382 secondary consequence, all string-to-float and float-to-string
6383 conversions (including all float formatting operations) will be
6384 correctly rounded on these platforms.
6385
Georg Brandl5f90d792010-08-01 22:31:05 +00006386 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006387 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006389- Issue #5759: float() didn't call __float__ on str subclasses.
6390
Georg Brandlabc38772009-04-12 15:51:51 +00006391- The string.maketrans() function is deprecated; there is a new static method
6392 maketrans() on the bytes and bytearray classes. This removes confusion about
6393 the types string.maketrans() is supposed to work with, and mirrors the
6394 methods available on the str class.
6395
R. David Murraydc6da8a2009-04-09 22:16:43 +00006396- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

6563 untrackable objects are not tracked by the garbage collector. This can
6564 reduce the size of collections and therefore the garbage collection overhead
6565 on long-running programs, depending on their particular use of datatypes.

6573 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6574 --enable-big-digits option to configure, which overrides the
6575 default. Add sys.int_info structseq to provide information about
6576 the internal format.

6630 (typically /dev/zero under Unix) could crash the interpreter.
6631
Benjamin Peterson59406a92009-03-26 17:10:29 +00006632- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

6634
Lars Gustäbel42e00912009-03-22 20:34:29 +00006635- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6636 forever on incomplete input. That caused tarfile.open() to hang when used
6637 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6638 partial bzip2 compressed data.
6639
Mark Dickinson79f52032009-03-17 23:12:51 +00006640- Issue #2110: Add support for thousands separator and 'n' type

6644 '>' alignment characters.
6645
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00006646- The error detection code in FileIO.close() could fail to reflect the `errno`

6658 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00006659 struct.error instead of returning b'\xff\xff\xff\xff'. The
6660 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
6661 have been removed from the struct module.

6677 used when using str.format() with str, int, and float arguments.
6678
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006679- Issue #5249: time.strftime returned malformed string when format string
6680 contained non ascii character on windows.
6681
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006682- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6683 source has already been decoded into str.
6684
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006685- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6686 rotating the object pointer by 4 bits to the right.
6687
Mark Dickinson87ec0852009-02-09 17:15:59 +00006688- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6689 it now forces its argument to double before testing for infinity.
6690
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006691- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6692 returns a non-number type.
6693
Benjamin Peterson87618552009-02-08 15:00:52 +00006694- Issue #5182: Removed memoryview.__str__.
6695
Mark Dickinsonc008a172009-02-01 13:59:22 +00006696- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6697 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006698 the type definition cmpfunc. The tp_compare slot has been renamed
6699 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006700
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006701- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006702 were suppressing all exceptions. These include list() and bytearray().
6703
Mark Dickinson1124e712009-01-28 21:25:58 +00006704- Issue #4707: round(x, n) now returns an integer if x is an integer.
6705 Previously it returned a float.
6706
Antoine Pitroub52ec782009-01-25 16:34:23 +00006707- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6708 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6709 evaluation loop is compiled with a new dispatch mechanism which gives
6710 speedups of up to 20%, depending on the system, on various benchmarks.
6711
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006712- Issue #4874: Most builtin decoders now reject unicode input.

6718
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006719- Issue #4838: When a module is deallocated, free the memory backing the
6720 optional module state data.
6721
Mark Dickinson8055afd2009-01-17 10:04:45 +00006722- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006723 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006724
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006725- Issue #4935: The overflow checking code in the expandtabs() method common
6726 to str, bytes and bytearray could be optimized away by the compiler, letting
6727 the interpreter segfault instead of raising an error.
6728
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006729- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6730 __next__ method.
6731
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006732- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6733 function no longer attempt to call the __long__ slot to convert an object
6734 to an integer. Only the __int__ and __trunc__ slots are examined.
6735
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006736- Issue #4893: Use NT threading on CE.
6737
Martin v. Löwisec59d042009-01-12 07:59:10 +00006738- Issue #4915: Port sysmodule to Windows CE.
6739
Antoine Pitrouab868312009-01-10 15:40:25 +00006740- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6741 common cases are optimized thanks to a dedicated fast path and a moderate
6742 amount of loop unrolling.
6743
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006744- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6745 collecting the oldest generation) so that allocating lots of objects without
6746 destroying them does not show quadratic performance. Based on a proposal by
6747 Martin von Löwis at
6748 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6749
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006750- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006751 having been closed (for instance, a read() call could return some
6752 previously buffered data). Patch by Dmitry Vasiliev.
6753
Antoine Pitrou05608432009-01-09 18:53:14 +00006754- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6755 flag to work properly. Furthermore, when specifying -u, the text stdout
6756 and stderr streams have line-by-line buffering enabled (the default being
6757 to buffer arbitrary chunks of data).
6758
Raymond Hettinger35631532009-01-09 03:58:09 +00006759- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6760 instead of ints (reducing its size from 4 to 8 times thereby reducing
6761 Python's overall memory).
6762
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006763- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6764 an existing .py counterpart, override the co_filename attributes of all
6765 code objects if the original filename is obsolete (which can happen if the
6766 file has been renamed, moved, or if it is accessed through different paths).
6767 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6768
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006769- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6770 one byte. Also fixes the meaning of len() so that it returns the number of
6771 items, rather than the size in bytes.
6772
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006773- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6774
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006775- Issue #4747: When the terminal does not use utf-8, executing a script with
6776 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6777
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006778- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6779 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006780
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006781- Issue #3680: Reference cycles created through a dict, set or deque iterator
6782 did not get collected.
6783
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006784- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6785 where the tp_hash and tp_dict slots are both NULL.
6786
Georg Brandlccc47b62008-12-28 11:44:14 +00006787- Issue #4759: None is now allowed as the first argument of
6788 bytearray.translate(). It was always allowed for bytes.translate().
6789
Skip Montanaro80072cb2008-12-23 03:51:14 +00006790- Added test case to ensure attempts to read from a file opened for writing
6791 fail.
6792
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006793- Issue #3106: Speedup some comparisons (str/str and int/int).

6797
Antoine Pitrou621601a2008-12-17 23:18:19 +00006798- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6799 print elapsed times, not only when some objects are uncollectable /
6800 unreachable. Original patch by Neil Schemenauer.
6801
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006802- Issue #3439: Add a bit_length method to int.
6803
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006804- Issue #2173: When getting device encoding, check that return value of
6805 nl_langinfo is not the empty string. This was causing silent build
6806 failures on OS X.
6807
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006808- Issue #4597: Fixed several opcodes that weren't always propagating
6809 exceptions.
6810
6811- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006812 context manager returns a value that cannot be converted to a bool.
6813
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006814- Issue #4445: Replace "sizeof(PyBytesObject)" with
6815 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6816 bytes instances. On a typical machine this saves 3 bytes of memory
6817 (on average) per allocation of a bytes instance.
6818
Christian Heimesa872de52008-12-05 08:26:55 +00006819- Issue #4533: File read operation was dreadfully slow due to a slowly
6820 growing read buffer. Fixed by using the same growth rate algorithm as
6821 Python 2.x.
6822
Antoine Pitrou5504e892008-12-06 21:27:53 +00006823- Issue #4509: Various issues surrounding resize of bytearray objects to
6824 which there are buffer exports (e.g. memoryview instances).
6825
Georg Brandlf9734072008-12-07 15:30:06 +00006826- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6827 method on file objects with closefd=False. The file descriptor is still
6828 kept open but the file object behaves like a closed file. The ``FileIO``
6829 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006830
Antoine Pitroubc420402008-12-07 20:14:49 +00006831- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6832 larger than 1.

6837
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006838- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6839 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6840 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6841 of using the replace error handler in PyUnicode_DecodeUTF8().
