78 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +000079 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +000080 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +000081 encoding and to encode command line arguments on this OS.

Georg Brandl4fbc0d82010-11-13 13:25:40 +0000125- Issue #10386: Add __all__ to token module; this simplifies importing in

Georg Brandl4fbc0d82010-11-13 13:25:40 +0000134 unexpectedly if the return value of a task could not be pickled. Only the

139 ``multiprocessing.Pool`` now accepts a ``error_callback`` argument. This can
140 be a callback with the signature ``callback(exc)``, which will be called if
141 the target raises an exception.

196 your app validates with Python <3.2b1+, but not on this version, it is likely

460 Py_Initialize().
461
Georg Brandl27a28582010-10-10 09:49:21 +0000462- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +0000471- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
472 with a non-empty format string. This is an effort to future-proof user
473 code. If a derived class does not currently implement __format__ but later
474 adds its own __format__, it would most likely break user code that had
475 supplied a format string. This will be changed to a DeprecationWaring in
476 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +0000478- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

480 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +0000482- Issue #9210: Configure option --with-wctype-functions was removed. Using the
483 functions from the libc caused the methods .upper() and lower() to become
484 locale aware and created subtly wrong results.
485
Georg Brandl27a28582010-10-10 09:49:21 +0000486- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +0000489- Issue #4617: Previously it was illegal to delete a name from the local
490 namespace if it occurs as a free variable in a nested block. This limitation
491 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
492
Georg Brandl27a28582010-10-10 09:49:21 +0000493- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
494 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
495 Also, the "backslashreplace" error handler now joins surrogate pairs into a
496 single character on UCS-2 builds.

499 underlying buffer (previously this was only done when deallocating the
500 memoryview), and gain support for the context management protocol.
501
Antoine Pitrou079ce542010-09-08 12:37:10 +0000502- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +0000531- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000532 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +0000533 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +0000534 replacement for old handle_accept() and avoids the user to call accept()
535 directly.

Georg Brandl27a28582010-10-10 09:49:21 +0000559 retry the select() loop instead of bailing out. This is because select() can
560 incorrectly report a socket as ready for reading (for example, if it received
561 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +0000641- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +0000642 it possible for the user to create self-referencing ordered dictionaries which
643 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +0000644 approach of using weakref proxies so that reference cycles never get created
645 in the first place.
646
Victor Stinnercb043522010-09-10 23:49:04 +0000647- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
648 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +0000649 utf-8 in strict mode) . Patch written by David Watson.

Georg Brandl27a28582010-10-10 09:49:21 +0000651- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
652 environment variable to set the filesystem encoding at Python startup.
653 sys.setfilesystemencoding() creates inconsistencies because it is unable to
654 reencode all filenames in all objects.

667 friendlier towards reference cycles. This change is not normally visible
668 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +0000670- Issue #6394: os.getppid() is now supported on Windows. Note that it will
671 still return the id of the parent process after it has exited. This process
672 id may even have been reused by another unrelated process.
673
Georg Brandl27a28582010-10-10 09:49:21 +0000674- Issue #9792: In case of connection failure, socket.create_connection() would
675 swallow the exception and raise a new one, making it impossible to fetch the
676 original errno, or to filter timeout errors. Now the original error is
677 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +0000688 * Update the seed() method to use all of the bits in a string instead of just
689 the hash value. This makes better use of the seed value and assures the
690 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +0000691
Georg Brandl27a28582010-10-10 09:49:21 +0000692 * Improved the random()-->integer algorithm used in choice(), shuffle(),
693 sample(), randrange(), and randint(). Formerly, it used int(n*random())
694 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +0000695
696 * Improved documentation of arguments to randrange(). Issue #9379.

717 guaranteed to exist in all Python implementations and the names of hash
718 algorithms available in the current process.

848 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

888 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +0000889
890 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
891 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

1226 the number of bytes specified by the start byte. E.g.:

1228 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
1229 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
1230 returned a single u'\ufffd'.

1303 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00001304 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
1305 (2) The comparison raised an OverflowError for large integers, leading to

1745 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00001746 applications that use a lot of regular expressions and limits the impact of
1747 the performance hit anytime the cache is exceeded.

2158 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2159 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00002161- Issue #2531: Comparison operations between floats and Decimal instances now
2162 return a result based on the numeric values of the operands; previously they
2163 returned an arbitrary result based on the relative ordering of id(float) and
2164 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
2165 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00002169- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00002170 argument `-` which tells it to read files to compile from stdin. Each line is
2171 read on demand and the named file is compiled immediately. (Original patch by
2172 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00002174- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00002178- Comparisons using one of <, <=, >, >= between a complex instance and a
2179 Fractions instance now raise TypeError instead of returning True/False. This
2180 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2181 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00002224- The internals of the subprocess module on POSIX systems have been replaced by
2225 an extension module (_posixsubprocess) so that the fork()+exec() can be done
2226 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00002228- subprocess.Popen now has restore_signals and start_new_session features. The
2229 default of restore_signals=True is a new behavior compared to earlier Python
2230 versions. This means that signals such as SIGPIPE are not ignored by default
2231 in subprocesses launched by Python (Issue #1652).

2318 position when calling `truncate()`. It would previously change the file
2319 position to the given argument, which goes against the tradition of

2324 archive. The new implementation is significantly faster and can be wrapped in
2325 a :class:`io.BufferedReader` object for more speedups. It also solves an
2326 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00002662- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00002663 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
2664 PyPycLoader inherit from this class and provide implementations in relation to
2665 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00002724- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00002725 compared to other unix systems. In particular, os.getgroups() does not reflect
2726 any changes made using os.setgroups() but basicly always returns the same
2727 information as the id command. os.getgroups() can now return more than 16
2728 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00002753- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
2754 Prior to this change, timezone adjustment in utctimetuple() could produce
2755 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00002758- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
2759 directive. When the ``%z`` directive is present in the format string, an
2760 aware ``datetime`` object is returned with ``tzinfo`` bound to a
2761 ``datetime.timezone`` instance constructed from the parsed offset. If both
2762 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
2763 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00002766 implementing ``datetime.tzinfo`` interface. Instances of the new class,
2767 ``datetime.timezone``, return fixed name and UTC offset from their
2768 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
2769 returns ``None``. A class attribute, ``utc`` contains an instance
2770 representing the UTC timezone. Original patch by Rafe Kaplan.

2787 with an improved 'binary-split' algorithm that uses fewer multiplications and
2788 allows many of the multiplications to be performed using plain C integer
2789 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

Georg Brandl62069d32010-07-31 08:56:11 +00002797 the result is now always correctly rounded, and is equivalent to ``td /

Mark Dickinson865e01a2009-05-07 16:37:01 +00003376- Issue #5914: Add new C API function PyOS_string_to_double, and
3377 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
3378
Eric Smith741191f2009-05-06 13:08:15 +00003379- Issue #3382: float.__format__, complex.__format__, and %-formatting

3386
Eric Smith63376222009-05-05 14:04:18 +00003387- Issue #5920: For float.__format__, change the behavior with the

3389 to be like 'g' but with at least one decimal point and with a
3390 default precision of 12. Previously, the behavior the same but with
3391 a default precision of 6. This more closely matches str(), and
3392 reduces surprises when adding alignment flags to the empty
3393 presentation type. This also affects the new complex.__format__ in
3394 the same way.
3395
Martin v. Löwis011e8422009-05-05 04:43:17 +00003396- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00003398- Issue #5890: in subclasses of 'property' the __doc__ attribute was
3399 shadowed by classtype's, even if it was None. property now
3400 inserts the __doc__ into the subclass instance __dict__.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00003407- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
3408 received a new method, detach(). detach() disconnects the underlying stream
3409 from the buffer or text IO and returns it.
3410
Mark Dickinson33841c32009-05-01 15:37:04 +00003411- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
3412 floats with absolute value over 1e50. Also remove length
3413 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
3414 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00003416- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00003417 format(complex(1, 2./3), '.5') now produces a sensible result.
3418
Mark Dickinsond3ca5572009-04-29 18:47:07 +00003419- Issue #5864: Fix empty format code formatting for floats so that it
3420 never gives more than the requested number of significant digits.
3421
Eric Smith6dc46f52009-04-27 20:39:49 +00003422- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

3433 z involves nans, infs or negative zeros.
3434
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00003435- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00003436
Mark Dickinsone6a076d2009-04-18 11:48:33 +00003437- Issue #1869 (and many duplicates): make round(x, n) correctly
3438 rounded for a float x, by using the decimal <-> binary conversions
3439 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
3440 consistently agrees with format(x, '.2f').
3441
Benjamin Petersonae937c02009-04-18 20:54:08 +00003442- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
3443 some builtin types.
3444
Eric Smith0923d1d2009-04-16 20:16:10 +00003445- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
3446
Eric Smith35e84722009-04-16 20:21:28 +00003447- Issue #5515: str.format() type 'n' combined with commas and leading
3448 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00003449
3450- Implement PEP 378, Format Specifier for Thousands Separator, for
3451 floats.
3452
Mark Dickinson3370cce2009-04-17 22:40:53 +00003453- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003454 1e11, not 1e12. This avoids printing 13 significant digits in
3455 situations where only 12 of them are correct. Example problem
3456 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
3457 long time.)
3458
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003459- Issue #1580: On most platforms, use a 'short' float repr: for a
3460 finite float x, repr(x) now outputs a string based on the shortest
3461 sequence of decimal digits that rounds to x. Previous behaviour was
3462 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00003463 Another minor difference is that the new repr switches to
3464 exponential notation at 1e16 instead of the previous 1e17; this
3465 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003466
3467 There's a new sys attribute sys.float_repr_style, which takes
3468 the value 'short' to indicate that we're using short float repr,
3469 and 'legacy' if the short float repr isn't available for one
3470 reason or another.
3471
3472 The float repr change involves incorporating David Gay's 'perfect
3473 rounding' code into the Python core (it's in Python/dtoa.c). As a
3474 secondary consequence, all string-to-float and float-to-string
3475 conversions (including all float formatting operations) will be
3476 correctly rounded on these platforms.
3477
Georg Brandl5f90d792010-08-01 22:31:05 +00003478 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00003479 this change does not apply.
3480
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00003481- Issue #5759: float() didn't call __float__ on str subclasses.
3482
Georg Brandlabc38772009-04-12 15:51:51 +00003483- The string.maketrans() function is deprecated; there is a new static method
3484 maketrans() on the bytes and bytearray classes. This removes confusion about
3485 the types string.maketrans() is supposed to work with, and mirrors the
3486 methods available on the str class.
3487
R. David Murraydc6da8a2009-04-09 22:16:43 +00003488- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

3493
Walter Dörwald8dc33d52009-05-06 14:41:26 +00003494- Issue #3739: The unicode-internal encoder now reports the number of characters

3655 untrackable objects are not tracked by the garbage collector. This can
3656 reduce the size of collections and therefore the garbage collection overhead
3657 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00003780- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
3781 it now forces its argument to double before testing for infinity.
3782
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00003783- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
3784 returns a non-number type.
3785
Benjamin Peterson87618552009-02-08 15:00:52 +00003786- Issue #5182: Removed memoryview.__str__.
3787
Mark Dickinsonc008a172009-02-01 13:59:22 +00003788- Issue #1717: Removed builtin cmp() function, dropped tp_compare

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00003792
Georg Brandl1cdd83c2009-04-05 20:24:29 +00003793- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00003794 were suppressing all exceptions. These include list() and bytearray().
3795
Mark Dickinson1124e712009-01-28 21:25:58 +00003796- Issue #4707: round(x, n) now returns an integer if x is an integer.
3797 Previously it returned a float.
3798
Antoine Pitroub52ec782009-01-25 16:34:23 +00003799- Issue #4753: By enabling a configure option named '--with-computed-gotos'
3800 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
3801 evaluation loop is compiled with a new dispatch mechanism which gives
3802 speedups of up to 20%, depending on the system, on various benchmarks.
3803
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00003804- Issue #4874: Most builtin decoders now reject unicode input.

3812 optional module state data.
3813
Mark Dickinson8055afd2009-01-17 10:04:45 +00003814- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003815 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00003816
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00003817- Issue #4935: The overflow checking code in the expandtabs() method common
3818 to str, bytes and bytearray could be optimized away by the compiler, letting
3819 the interpreter segfault instead of raising an error.
3820
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00003821- Issue #3720: Fix a crash when an iterator modifies its class and removes its
3822 __next__ method.
3823
Mark Dickinsone5e298f2009-01-12 20:49:19 +00003824- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
3825 function no longer attempt to call the __long__ slot to convert an object
3826 to an integer. Only the __int__ and __trunc__ slots are examined.
3827
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00003828- Issue #4893: Use NT threading on CE.
3829

3831
Antoine Pitrouab868312009-01-10 15:40:25 +00003832- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
3833 common cases are optimized thanks to a dedicated fast path and a moderate
3834 amount of loop unrolling.
3835
Antoine Pitrou14b78f52009-01-09 22:27:08 +00003836- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3837 collecting the oldest generation) so that allocating lots of objects without
3838 destroying them does not show quadratic performance. Based on a proposal by
3839 Martin von Löwis at
3840 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
3841
Vinay Sajip6268cbc2009-01-21 00:19:28 +00003842- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00003843 having been closed (for instance, a read() call could return some
3844 previously buffered data). Patch by Dmitry Vasiliev.
3845
Antoine Pitrou05608432009-01-09 18:53:14 +00003846- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
3847 flag to work properly. Furthermore, when specifying -u, the text stdout
3848 and stderr streams have line-by-line buffering enabled (the default being
3849 to buffer arbitrary chunks of data).
3850
Raymond Hettinger35631532009-01-09 03:58:09 +00003851- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
3852 instead of ints (reducing its size from 4 to 8 times thereby reducing
3853 Python's overall memory).
3854
Antoine Pitroud35cbf62009-01-06 19:02:24 +00003855- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
3856 an existing .py counterpart, override the co_filename attributes of all
3857 code objects if the original filename is obsolete (which can happen if the
3858 file has been renamed, moved, or if it is accessed through different paths).
3859 Patch by Ziga Seilnacht and Jean-Paul Calderone.
3860
Antoine Pitrouc3b39242009-01-03 16:59:18 +00003861- Issue #4580: Fix slicing of memoryviews when the item size is greater than
3862 one byte. Also fixes the meaning of len() so that it returns the number of
3863 items, rather than the size in bytes.
3864
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003865- Issue #4075: Use OutputDebugStringW in Py_FatalError.
3866
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00003867- Issue #4747: When the terminal does not use utf-8, executing a script with
3868 non-ascii characters in its name could fail with a "SyntaxError: None" error.
3869
Georg Brandl65ce6ad2010-09-05 17:32:31 +00003870- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
3871 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00003872
Antoine Pitrou7ddda782009-01-01 15:35:33 +00003873- Issue #3680: Reference cycles created through a dict, set or deque iterator
3874 did not get collected.
3875
Nick Coghlanf1f2f682008-12-30 07:29:12 +00003876- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
3877 where the tp_hash and tp_dict slots are both NULL.
3878
Georg Brandlccc47b62008-12-28 11:44:14 +00003879- Issue #4759: None is now allowed as the first argument of
3880 bytearray.translate(). It was always allowed for bytes.translate().
3881
Skip Montanaro80072cb2008-12-23 03:51:14 +00003882- Added test case to ensure attempts to read from a file opened for writing
3883 fail.
3884
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00003885- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00003887- Issue #2183: Simplify and optimize bytecode for list, dict and set
3888 comprehensions. Original patch for list comprehensions by Neal Norwitz.
3889
Antoine Pitrou621601a2008-12-17 23:18:19 +00003890- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
3891 print elapsed times, not only when some objects are uncollectable /
3892 unreachable. Original patch by Neil Schemenauer.
3893
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00003894- Issue #3439: Add a bit_length method to int.
3895
Mark Dickinsonda2706b2008-12-11 18:03:03 +00003896- Issue #2173: When getting device encoding, check that return value of
3897 nl_langinfo is not the empty string. This was causing silent build
3898 failures on OS X.
3899
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00003900- Issue #4597: Fixed several opcodes that weren't always propagating
3901 exceptions.
3902
3903- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00003904 context manager returns a value that cannot be converted to a bool.
3905
Mark Dickinsonfd24b322008-12-06 15:33:31 +00003906- Issue #4445: Replace "sizeof(PyBytesObject)" with
3907 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
3908 bytes instances. On a typical machine this saves 3 bytes of memory
3909 (on average) per allocation of a bytes instance.
3910
Christian Heimesa872de52008-12-05 08:26:55 +00003911- Issue #4533: File read operation was dreadfully slow due to a slowly
3912 growing read buffer. Fixed by using the same growth rate algorithm as
3913 Python 2.x.
3914
Antoine Pitrou5504e892008-12-06 21:27:53 +00003915- Issue #4509: Various issues surrounding resize of bytearray objects to
3916 which there are buffer exports (e.g. memoryview instances).
3917
Georg Brandlf9734072008-12-07 15:30:06 +00003918- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
3919 method on file objects with closefd=False. The file descriptor is still
3920 kept open but the file object behaves like a closed file. The ``FileIO``
3921 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00003922
Antoine Pitroubc420402008-12-07 20:14:49 +00003923- Issue #4569: Interpreter crash when mutating a memoryview with an item size
3924 larger than 1.

3929
Walter Dörwaldc1651a02009-05-03 22:55:55 +00003930- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
3931 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3932 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3933 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00004538- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4539 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
4540 the same behaviour as test_ttkguionly (and now also test_tk) which is to

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00004544 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00004545 from test support, which does the conversion.
