Ned Deily657b2de2011-06-28 19:51:30 -0700788- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
789 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
790 interpreter process. This could cause failures in non-Distutils subprocesses
791 and was unreliable since tests or user programs could modify the interpreter
792 environment after Distutils set it. Instead, have Distutils set the the
793 deployment target only in the environment of each build subprocess. It is
794 still possible to globally override the default by setting
795 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
796 greater or equal to the default value, the value with which the interpreter

Georg Brandl0c5036f2011-01-16 08:44:50 +00001943 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00001944 that for incoming headers which makes this behaviour now consistent in
1945 both incoming and outgoing direction.

Georg Brandl255abdd2011-01-16 14:17:26 +00002042 continuation line in the formatted value has no leading white space and looks
2043 like a header. Since Generator uses Header to format all headers, this check
2044 is made for all headers in any serialized message at serialization time. This
2045 provides protection against header injection attacks.

Georg Brandl255abdd2011-01-16 14:17:26 +00002055 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00002056
Éric Araujof0ab5d62011-05-29 03:43:59 +02002057- email.header.Header was incorrectly encoding folding whitespace when

2059 folding whitespace. It now uses the continuation_ws, as it does for

2063 time.asctime(), time.ctime() and time.strftime() functions will now format

2065 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
2066 supported by the OS. With Visual Studio or on Solaris, the year is limited to
2067 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002701 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Georg Brandl27a28582010-10-10 09:49:21 +00003054- ast.literal_eval() can now handle negative numbers. It is also a little more
3055 liberal in what it accepts without compromising the safety of the evaluation.
3056 For example, 3j+4 and 3+4+5 are both accepted.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003078- Issue #9930: Remove bogus subtype check that was causing (e.g.)

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003083- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3084 threads are still running. Instead, reinitialize the GIL on a second call to
3085 Py_Initialize().
3086
Georg Brandl27a28582010-10-10 09:49:21 +00003087- All SyntaxErrors now have a column offset and therefore a caret when the error
3088 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00003090- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3091 module that was imported, but instead gets the module from sys.modules.
3092
Nick Coghlan37ee8502010-12-03 14:26:13 +00003093- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00003096- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3097 with a non-empty format string. This is an effort to future-proof user
3098 code. If a derived class does not currently implement __format__ but later
3099 adds its own __format__, it would most likely break user code that had
3100 supplied a format string. This will be changed to a DeprecationWaring in
3101 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00003102
Antoine Pitrou1df15362010-09-13 14:16:46 +00003103- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3104 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3105 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3106
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003107- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3108 functions from the libc caused the methods .upper() and lower() to become
3109 locale aware and created subtly wrong results.
3110
Georg Brandl27a28582010-10-10 09:49:21 +00003111- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3112 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003113
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003114- Issue #4617: Previously it was illegal to delete a name from the local
3115 namespace if it occurs as a free variable in a nested block. This limitation
3116 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3117
Georg Brandl27a28582010-10-10 09:49:21 +00003118- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3119 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3120 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3121 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00003122
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003123- Issue #9757: memoryview objects get a release() method to release the
3124 underlying buffer (previously this was only done when deallocating the
3125 memoryview), and gain support for the context management protocol.
3126
Antoine Pitrou079ce542010-09-08 12:37:10 +00003127- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3128 thread-local storage key.

3155
Éric Araujoef777bd2010-10-05 00:04:20 +00003156- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003157 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003158 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003159 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003184 retry the select() loop instead of bailing out. This is because select() can

Antoine Pitrou98b46702010-09-18 22:59:00 +00003232- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00003233 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003266- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003267 it possible for the user to create self-referencing ordered dictionaries which
3268 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003269 approach of using weakref proxies so that reference cycles never get created
3270 in the first place.

3278 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3279 reencode all filenames in all objects.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003295- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3296 still return the id of the parent process after it has exited. This process
3297 id may even have been reused by another unrelated process.
3298
Georg Brandl27a28582010-10-10 09:49:21 +00003299- Issue #9792: In case of connection failure, socket.create_connection() would
3300 swallow the exception and raise a new one, making it impossible to fetch the
3301 original errno, or to filter timeout errors. Now the original error is
3302 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003304- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3305 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3306 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003308- Updates to the random module:
3309
Georg Brandl27a28582010-10-10 09:49:21 +00003310 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00003313 * Update the seed() method to use all of the bits in a string instead of just
3314 the hash value. This makes better use of the seed value and assures the
3315 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003317 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3318 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3319 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003320
3321 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003340- hashlib has two new constant attributes: algorithms_guaranteed and
3341 algorithms_avaiable that respectively list the names of hash algorithms
3342 guaranteed to exist in all Python implementations and the names of hash
3343 algorithms available in the current process.

Georg Brandl62069d32010-07-31 08:56:11 +00003856 start byte and the continuation byte(s) are now considered invalid, instead of
3857 the number of bytes specified by the start byte. E.g.:
3858 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3859 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3860 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3861 returned a single u'\ufffd'.

3934 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003935 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3936 (2) The comparison raised an OverflowError for large integers, leading to
3937 unpredictable exceptions when combining integers and complex objects in sets

4268 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4269 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004270 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00004373- The default size of the re module's compiled regular expression cache has been
4374 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00004375 simply clearing the entire cache on overflow to forgetting the least recently
4376 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004377 applications that use a lot of regular expressions and limits the impact of
4378 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004632- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4633 operation raises multiple signals and more than one of those signals is
4634 trapped, the specification determines the order in which the signals should be

Georg Brandl62069d32010-07-31 08:56:11 +00004792- Issue #2531: Comparison operations between floats and Decimal instances now
4793 return a result based on the numeric values of the operands; previously they

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005355- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005356 compared to other unix systems. In particular, os.getgroups() does not reflect
5357 any changes made using os.setgroups() but basicly always returns the same
5358 information as the id command. os.getgroups() can now return more than 16
5359 groups on MacOSX.

5385 Prior to this change, timezone adjustment in utctimetuple() could produce
5386 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

5390 directive. When the ``%z`` directive is present in the format string, an
5391 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5392 ``datetime.timezone`` instance constructed from the parsed offset. If both
5393 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5394 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00005397 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5398 ``datetime.timezone``, return fixed name and UTC offset from their
5399 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5400 returns ``None``. A class attribute, ``utc`` contains an instance
5401 representing the UTC timezone. Original patch by Rafe Kaplan.

5418 with an improved 'binary-split' algorithm that uses fewer multiplications and
5419 allows many of the multiplications to be performed using plain C integer
5420 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Mark Dickinson0381e3f2010-05-08 14:35:02 +00005426- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5427 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005428 the result is now always correctly rounded, and is equivalent to ``td /
5429 timedelta(seconds=1)``.

5438 integer format code, struct.pack first attempts to convert the non-integer
5439 using its __index__ method. If that method is non-existent or raises
5440 TypeError it goes on to try the __int__ method, as described below.

6020 to be like 'g' but with at least one decimal point and with a
6021 default precision of 12. Previously, the behavior the same but with
6022 a default precision of 6. This more closely matches str(), and
6023 reduces surprises when adding alignment flags to the empty
6024 presentation type. This also affects the new complex.__format__ in
6025 the same way.

6065
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006066- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006067
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006068- Issue #1869 (and many duplicates): make round(x, n) correctly
6069 rounded for a float x, by using the decimal <-> binary conversions
6070 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6071 consistently agrees with format(x, '.2f').
6072
Benjamin Petersonae937c02009-04-18 20:54:08 +00006073- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

6075
Eric Smith0923d1d2009-04-16 20:16:10 +00006076- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6077
Eric Smith35e84722009-04-16 20:21:28 +00006078- Issue #5515: str.format() type 'n' combined with commas and leading
6079 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006080
6081- Implement PEP 378, Format Specifier for Thousands Separator, for
6082 floats.
6083
Mark Dickinson3370cce2009-04-17 22:40:53 +00006084- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006085 1e11, not 1e12. This avoids printing 13 significant digits in
6086 situations where only 12 of them are correct. Example problem
6087 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6088 long time.)
6089
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006090- Issue #1580: On most platforms, use a 'short' float repr: for a
6091 finite float x, repr(x) now outputs a string based on the shortest
6092 sequence of decimal digits that rounds to x. Previous behaviour was
6093 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006094 Another minor difference is that the new repr switches to
6095 exponential notation at 1e16 instead of the previous 1e17; this
6096 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006097
6098 There's a new sys attribute sys.float_repr_style, which takes
6099 the value 'short' to indicate that we're using short float repr,
6100 and 'legacy' if the short float repr isn't available for one
6101 reason or another.
6102
6103 The float repr change involves incorporating David Gay's 'perfect
6104 rounding' code into the Python core (it's in Python/dtoa.c). As a
6105 secondary consequence, all string-to-float and float-to-string
6106 conversions (including all float formatting operations) will be
6107 correctly rounded on these platforms.
6108
Georg Brandl5f90d792010-08-01 22:31:05 +00006109 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006110 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006112- Issue #5759: float() didn't call __float__ on str subclasses.
6113
Georg Brandlabc38772009-04-12 15:51:51 +00006114- The string.maketrans() function is deprecated; there is a new static method
6115 maketrans() on the bytes and bytearray classes. This removes confusion about
6116 the types string.maketrans() is supposed to work with, and mirrors the
6117 methods available on the str class.
6118
R. David Murraydc6da8a2009-04-09 22:16:43 +00006119- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

6286 untrackable objects are not tracked by the garbage collector. This can
6287 reduce the size of collections and therefore the garbage collection overhead
6288 on long-running programs, depending on their particular use of datatypes.

6296 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6297 --enable-big-digits option to configure, which overrides the
6298 default. Add sys.int_info structseq to provide information about
6299 the internal format.

Lars Gustäbel42e00912009-03-22 20:34:29 +00006358- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6359 forever on incomplete input. That caused tarfile.open() to hang when used
6360 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6361 partial bzip2 compressed data.
6362
Mark Dickinson79f52032009-03-17 23:12:51 +00006363- Issue #2110: Add support for thousands separator and 'n' type
6364 specifier to Decimal.__format__
6365
Mark Dickinson9c59fe02009-03-17 18:15:08 +00006366- Fix Decimal.__format__ bug that swapped the meanings of the '<' and
6367 '>' alignment characters.
6368
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00006369- The error detection code in FileIO.close() could fail to reflect the `errno`
6370 value, and report it as -1 instead.
6371
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00006372- Issue #5016: FileIO.seekable() could return False if the file position
6373 was negative when truncated to a C int. Patch by Victor Stinner.

Mark Dickinsonae681df2009-03-21 10:26:31 +00006380- Issue #5463: In struct module, remove deprecated overflow wrapping
6381 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00006382 struct.error instead of returning b'\xff\xff\xff\xff'. The
6383 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
6384 have been removed from the struct module.

6400 used when using str.format() with str, int, and float arguments.
6401
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006402- Issue #5249: time.strftime returned malformed string when format string
6403 contained non ascii character on windows.
6404
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006405- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6406 source has already been decoded into str.
6407
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006408- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6409 rotating the object pointer by 4 bits to the right.
6410
Mark Dickinson87ec0852009-02-09 17:15:59 +00006411- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6412 it now forces its argument to double before testing for infinity.
6413
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006414- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6415 returns a non-number type.
6416
Benjamin Peterson87618552009-02-08 15:00:52 +00006417- Issue #5182: Removed memoryview.__str__.
6418
Mark Dickinsonc008a172009-02-01 13:59:22 +00006419- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6420 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006421 the type definition cmpfunc. The tp_compare slot has been renamed
6422 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006423
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006424- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006425 were suppressing all exceptions. These include list() and bytearray().
6426
Mark Dickinson1124e712009-01-28 21:25:58 +00006427- Issue #4707: round(x, n) now returns an integer if x is an integer.
6428 Previously it returned a float.
6429
Antoine Pitroub52ec782009-01-25 16:34:23 +00006430- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6431 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6432 evaluation loop is compiled with a new dispatch mechanism which gives
6433 speedups of up to 20%, depending on the system, on various benchmarks.
6434
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006435- Issue #4874: Most builtin decoders now reject unicode input.

6441
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00006442- Issue #4838: When a module is deallocated, free the memory backing the
6443 optional module state data.
6444
Mark Dickinson8055afd2009-01-17 10:04:45 +00006445- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006446 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006447
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006448- Issue #4935: The overflow checking code in the expandtabs() method common
6449 to str, bytes and bytearray could be optimized away by the compiler, letting
6450 the interpreter segfault instead of raising an error.
6451
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006452- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6453 __next__ method.
6454
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006455- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6456 function no longer attempt to call the __long__ slot to convert an object
6457 to an integer. Only the __int__ and __trunc__ slots are examined.
6458
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006459- Issue #4893: Use NT threading on CE.
6460
Martin v. Löwisec59d042009-01-12 07:59:10 +00006461- Issue #4915: Port sysmodule to Windows CE.
6462
Antoine Pitrouab868312009-01-10 15:40:25 +00006463- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6464 common cases are optimized thanks to a dedicated fast path and a moderate
6465 amount of loop unrolling.
6466
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006467- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6468 collecting the oldest generation) so that allocating lots of objects without
6469 destroying them does not show quadratic performance. Based on a proposal by
6470 Martin von Löwis at
6471 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6472
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006473- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006474 having been closed (for instance, a read() call could return some
6475 previously buffered data). Patch by Dmitry Vasiliev.
6476
Antoine Pitrou05608432009-01-09 18:53:14 +00006477- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6478 flag to work properly. Furthermore, when specifying -u, the text stdout
6479 and stderr streams have line-by-line buffering enabled (the default being
6480 to buffer arbitrary chunks of data).
6481
Raymond Hettinger35631532009-01-09 03:58:09 +00006482- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6483 instead of ints (reducing its size from 4 to 8 times thereby reducing
6484 Python's overall memory).
6485
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006486- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6487 an existing .py counterpart, override the co_filename attributes of all
6488 code objects if the original filename is obsolete (which can happen if the
6489 file has been renamed, moved, or if it is accessed through different paths).
6490 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6491
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006492- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6493 one byte. Also fixes the meaning of len() so that it returns the number of
6494 items, rather than the size in bytes.
6495
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006496- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6497
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006498- Issue #4747: When the terminal does not use utf-8, executing a script with
6499 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6500
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006501- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6502 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006503
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006504- Issue #3680: Reference cycles created through a dict, set or deque iterator
6505 did not get collected.
6506
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006507- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6508 where the tp_hash and tp_dict slots are both NULL.
6509
Georg Brandlccc47b62008-12-28 11:44:14 +00006510- Issue #4759: None is now allowed as the first argument of
6511 bytearray.translate(). It was always allowed for bytes.translate().
6512
Skip Montanaro80072cb2008-12-23 03:51:14 +00006513- Added test case to ensure attempts to read from a file opened for writing
6514 fail.
6515
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006516- Issue #3106: Speedup some comparisons (str/str and int/int).

6520
Antoine Pitrou621601a2008-12-17 23:18:19 +00006521- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6522 print elapsed times, not only when some objects are uncollectable /
6523 unreachable. Original patch by Neil Schemenauer.
6524
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006525- Issue #3439: Add a bit_length method to int.
6526
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006527- Issue #2173: When getting device encoding, check that return value of
6528 nl_langinfo is not the empty string. This was causing silent build
6529 failures on OS X.
6530
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006531- Issue #4597: Fixed several opcodes that weren't always propagating
6532 exceptions.
6533
6534- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006535 context manager returns a value that cannot be converted to a bool.
6536
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006537- Issue #4445: Replace "sizeof(PyBytesObject)" with
6538 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6539 bytes instances. On a typical machine this saves 3 bytes of memory
6540 (on average) per allocation of a bytes instance.
6541
Christian Heimesa872de52008-12-05 08:26:55 +00006542- Issue #4533: File read operation was dreadfully slow due to a slowly
6543 growing read buffer. Fixed by using the same growth rate algorithm as
6544 Python 2.x.
6545
Antoine Pitrou5504e892008-12-06 21:27:53 +00006546- Issue #4509: Various issues surrounding resize of bytearray objects to
6547 which there are buffer exports (e.g. memoryview instances).
6548
Georg Brandlf9734072008-12-07 15:30:06 +00006549- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6550 method on file objects with closefd=False. The file descriptor is still
6551 kept open but the file object behaves like a closed file. The ``FileIO``
6552 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006553
Antoine Pitroubc420402008-12-07 20:14:49 +00006554- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6555 larger than 1.

6560
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006561- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6562 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6563 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6564 of using the replace error handler in PyUnicode_DecodeUTF8().
