632 interpreter process. This could cause failures in non-Distutils subprocesses
633 and was unreliable since tests or user programs could modify the interpreter
634 environment after Distutils set it. Instead, have Distutils set the the
635 deployment target only in the environment of each build subprocess. It is
636 still possible to globally override the default by setting
637 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
638 greater or equal to the default value, the value with which the interpreter
639 was built.

1482 is made for all headers in any serialized message at serialization time. This
1483 provides protection against header injection attacks.

1504 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1505 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

2481
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002482- Issue #10068: Global objects which have reference cycles with their module's
2483 dict are now cleared again. This causes issue #7140 to appear again.
2484
Victor Stinner257d38f2010-10-09 10:12:11 +00002485- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002486 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002487
Georg Brandl27a28582010-10-10 09:49:21 +00002488- ast.literal_eval() can now handle negative numbers. It is also a little more
2489 liberal in what it accepts without compromising the safety of the evaluation.
2490 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002491
Benjamin Peterson970d1882010-10-02 17:55:47 +00002492- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2493 result metaclasses can now be ABCs (see #9533).
2494
Victor Stinneraef57e32010-10-02 11:50:49 +00002495- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2496
Victor Stinner5593d8a2010-10-02 11:11:27 +00002497- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002498 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2499 32 bits wchar_t (eg. Linux in narrow build).

2505
Brett Cannon5305a992010-09-27 21:08:38 +00002506- Issue #7397: Mention that importlib.import_module() is probably what someone
2507 really wants to be using in __import__'s docstring.
2508
Georg Brandl27a28582010-10-10 09:49:21 +00002509- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2510 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002511
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002512- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002513 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002514
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002515- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2516
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002517- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2518 threads are still running. Instead, reinitialize the GIL on a second call to
2519 Py_Initialize().
2520
Georg Brandl27a28582010-10-10 09:49:21 +00002521- All SyntaxErrors now have a column offset and therefore a caret when the error
2522 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002523
Brett Cannonbc2eff32010-09-19 21:39:02 +00002524- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2525 module that was imported, but instead gets the module from sys.modules.
2526
Nick Coghlan37ee8502010-12-03 14:26:13 +00002527- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002528 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002529
Georg Brandl27a28582010-10-10 09:49:21 +00002530- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2531 with a non-empty format string. This is an effort to future-proof user
2532 code. If a derived class does not currently implement __format__ but later
2533 adds its own __format__, it would most likely break user code that had
2534 supplied a format string. This will be changed to a DeprecationWaring in
2535 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002536
Antoine Pitrou1df15362010-09-13 14:16:46 +00002537- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2538 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2539 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2540
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002541- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2542 functions from the libc caused the methods .upper() and lower() to become
2543 locale aware and created subtly wrong results.
2544
Georg Brandl27a28582010-10-10 09:49:21 +00002545- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2546 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002547
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002548- Issue #4617: Previously it was illegal to delete a name from the local
2549 namespace if it occurs as a free variable in a nested block. This limitation
2550 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2551
Georg Brandl27a28582010-10-10 09:49:21 +00002552- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2553 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2554 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2555 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002556
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002557- Issue #9757: memoryview objects get a release() method to release the
2558 underlying buffer (previously this was only done when deallocating the
2559 memoryview), and gain support for the context management protocol.
2560
Antoine Pitrou079ce542010-09-08 12:37:10 +00002561- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2562 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002578- Issue #4661: email can now parse bytes input and generate either converted
2579 7bit output or bytes output. Email version bumped to 5.1.0.
2580
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002581- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2582 verification for higher-level protocols.
2583
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002584- Issue #9759: GzipFile now raises ValueError when an operation is attempted

2586
Éric Araujo6108bf52010-10-04 23:52:37 +00002587- Issue #9042: Fix interaction of custom translation classes and caching in
2588 gettext.
2589
Éric Araujoef777bd2010-10-05 00:04:20 +00002590- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002591 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002592 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002593 replacement for old handle_accept() and avoids the user to call accept()
2594 directly.

Lars Gustäbel331b8002010-10-04 15:18:47 +00002596- Issue #9065: tarfile no longer uses "root" as the default for the uname and

R. David Murray5397e862010-10-02 15:58:26 +00002602- Issue #1050268: parseaddr now correctly quotes double quote and backslash

Georg Brandl27a28582010-10-10 09:49:21 +00002605- Issue #10004: quoprimime no longer generates a traceback when confronted with

2613 test suite has also been added.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002617- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002618 retry the select() loop instead of bailing out. This is because select() can
2619 incorrectly report a socket as ready for reading (for example, if it received
2620 some data with an invalid checksum).

Antoine Pitrou6464d5f2010-09-12 14:51:20 +00002694- Issue #9837: The read() method of ZipExtFile objects (as returned by
2695 ZipFile.open()) could return more bytes than requested.
2696
Georg Brandl27a28582010-10-10 09:49:21 +00002697- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
2698 d['x'] = d.
Raymond Hettingerdc08a142010-09-12 05:15:22 +00002699
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002700- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002701 it possible for the user to create self-referencing ordered dictionaries which
2702 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002703 approach of using weakref proxies so that reference cycles never get created
2704 in the first place.
2705
Victor Stinnercb043522010-09-10 23:49:04 +00002706- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
2707 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00002708 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00002709
Georg Brandl27a28582010-10-10 09:49:21 +00002710- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2711 environment variable to set the filesystem encoding at Python startup.
2712 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2713 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002714
Georg Brandl27a28582010-10-10 09:49:21 +00002715- Issue #9410: Various optimizations to the pickle module, leading to speedups
2716 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2717 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002718
Georg Brandl27a28582010-10-10 09:49:21 +00002719- The pprint module now supports printing OrderedDicts in their given order
2720 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002722- Logging: Added QueueHandler class to facilitate logging usage with
2723 multiprocessing.
2724
Georg Brandl27a28582010-10-10 09:49:21 +00002725- Issue #9707: Rewritten reference implementation of threading.local which is
2726 friendlier towards reference cycles. This change is not normally visible
2727 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00002728
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002729- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2730 still return the id of the parent process after it has exited. This process
2731 id may even have been reused by another unrelated process.
2732
Georg Brandl27a28582010-10-10 09:49:21 +00002733- Issue #9792: In case of connection failure, socket.create_connection() would
2734 swallow the exception and raise a new one, making it impossible to fetch the
2735 original errno, or to filter timeout errors. Now the original error is
2736 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002738- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2739 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2740 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002742- Updates to the random module:
2743
Georg Brandl27a28582010-10-10 09:49:21 +00002744 * Document which parts of the module are guaranteed to stay the same across
2745 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002746
Georg Brandl27a28582010-10-10 09:49:21 +00002747 * Update the seed() method to use all of the bits in a string instead of just
2748 the hash value. This makes better use of the seed value and assures the
2749 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002750
Georg Brandl27a28582010-10-10 09:49:21 +00002751 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2752 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2753 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002754
2755 * Improved documentation of arguments to randrange(). Issue #9379.

2761 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2762 given warning type was triggered by the code under test.

Georg Brandl27a28582010-10-10 09:49:21 +00002764- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2765 their contents without duplicating them. The view is both readable and
2766 writable.

2769
Antoine Pitrou0d739d72010-09-05 23:01:12 +00002770- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002771 unsupported operation is attempted (for example, writing to a file open only
2772 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00002774- hashlib has two new constant attributes: algorithms_guaranteed and
2775 algorithms_avaiable that respectively list the names of hash algorithms
2776 guaranteed to exist in all Python implementations and the names of hash
2777 algorithms available in the current process.
2778
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002779- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002869- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
2870 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
2871 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00002882- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2883 now removed, since their effect was inexistent in 3.x (the default encoding is
2884 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00002885

2904
Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00002905- Issue #5127: The C functions that access the Unicode Database now accept and
2906 return characters from the full Unicode range, even on narrow unicode builds
2907 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2908 in Python is that unicodedata.numeric() now returns the correct value for
2909 large code points, and repr() may consider more characters as printable.
2910
Victor Stinner6c00c142010-08-17 23:37:11 +00002911- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

2913 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
2914 function.

2926
Victor Stinner47fcb5b2010-08-13 23:59:58 +00002927- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00002928 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
2929 objects are output as-is.

Ezio Melotti57221d02010-07-01 07:32:02 +00003289- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003290 start byte and the continuation byte(s) are now considered invalid, instead of
3291 the number of bytes specified by the start byte. E.g.:
3292 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3293 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3294 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3295 returned a single u'\ufffd'.

Victor Stinner554f3f02010-06-16 23:33:54 +00003315 error handlers, the decoder only supports "strict" and "ignore" error

3324
Georg Brandl62069d32010-07-31 08:56:11 +00003325- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003326 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3327 location of the raised exception.

Georg Brandl62069d32010-07-31 08:56:11 +00003338- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3339 TypeError instead of giving a DeprecationWarning when a float is parsed using
3340 the 'L' code (for long long). (All other integer codes already raise
3341 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003342
Victor Stinner600d3be2010-06-10 12:00:55 +00003343- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3344 enable shortcuts for upper case encoding name. Add also a shortcut for
3345 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3346
Georg Brandl62069d32010-07-31 08:56:11 +00003347- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3348 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003349
3350- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003351 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003352 like bytearray.
3353
Georg Brandl62069d32010-07-31 08:56:11 +00003354- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003355 used anymore and it was never documented.
3356
Georg Brandl62069d32010-07-31 08:56:11 +00003357- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003362- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3363 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3364 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3365 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003366
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003367- Issue #8748: Fix two issues with comparisons between complex and integer
3368 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003369 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3370 (2) The comparison raised an OverflowError for large integers, leading to
3371 unpredictable exceptions when combining integers and complex objects in sets
3372 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003373

3376
Victor Stinner9ca9c252010-05-19 16:53:30 +00003377- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003378 encoding and surrogateescape error handler instead of the locale encoding to

Georg Brandl62069d32010-07-31 08:56:11 +00003381- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3382 of strict) error handler to escape surrogates.

Victor Stinnerae6265f2010-05-15 16:27:27 +00003384- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3385 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003386 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003387 back to UTF-8.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00003674- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
3675 variable argument list. `Py_VA_COPY` is equivalent to C99
3676 `va_copy`, but available on all python platforms.
3677
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003678- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3679 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3680 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003690- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003691 function declaration, which was kept for backwards compatibility reasons, is
3692 now removed (the macro was introduced in 1997!).

3702 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3703 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003704 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003714- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3715 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3716 accessing the d_type and d_name members of structures using PyDescr_COMMON.

3733 gives improved memory leak detection when running under Valgrind, while taking
3734 advantage of pymalloc at other times.

Antoine Pitrou3060c452010-08-13 16:27:38 +00003809 simply clearing the entire cache on overflow to forgetting the least recently
3810 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003811 applications that use a lot of regular expressions and limits the impact of
3812 the performance hit anytime the cache is exceeded.

3825 module is renamed to `_datetime` and if available, overrides all classes
3826 defined in datetime with fast C impementation. Python implementation is based
3827 on the original python prototype for the datetime module by Tim Peters with
3828 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004079- Issue #8354: The siginterrupt setting is now preserved for all signals, not
4080 just SIGCHLD.

Georg Brandl62069d32010-07-31 08:56:11 +00004104- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
4105 the method could block indefinitely if called just before the event loop

Georg Brandl62069d32010-07-31 08:56:11 +00004109- Issue #8524: When creating an SSL socket, the timeout value of the original
4110 socket wasn't retained (instead, a socket with a positive timeout would be
4111 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00004112
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004113- Issue #5103: SSL handshake would ignore the socket timeout and block
4114 indefinitely if the other end didn't respond.
4115
Georg Brandl62069d32010-07-31 08:56:11 +00004116- The do_handshake() method of SSL objects now adjusts the blocking mode of the
4117 SSL structure if necessary (as other methods already do).

Georg Brandl62069d32010-07-31 08:56:11 +00004132- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
4133 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00004134 wanting to continue using the socket in clear-text mode, by disabling

4170
Victor Stinner0e59cc32010-04-16 23:49:32 +00004171- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for

4183
Georg Brandl62069d32010-07-31 08:56:11 +00004184- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004185 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004186 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004187
Victor Stinner485fb562010-04-13 11:07:24 +00004188- Issue #8383: pickle and pickletools use surrogatepass error handler when
4189 encoding unicode as utf8 to support lone surrogates and stay compatible with
Georg Brandl62069d32010-07-31 08:56:11 +00004190 Python 2.x and 3.x.

R. David Murrayb2416e52010-04-12 16:58:02 +00004192- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00004193 filename and date, conforming to the 'standards' they were originally designed
4194 to follow. This improves compatibility with patch tools.

Antoine Pitrou04f6a322010-04-05 21:40:07 +00004206- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandl62069d32010-07-31 08:56:11 +00004207 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4208 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00004209
Raymond Hettingerc50846a2010-04-05 18:56:31 +00004210- Add functools.total_ordering() and functools.cmp_to_key().
4211
Georg Brandl62069d32010-07-31 08:56:11 +00004212- Issue #8257: The Decimal construct now accepts a float instance directly,
4213 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00004214
4215 >>> Decimal(1.1)
4216 Decimal('1.100000000000000088817841970012523233890533447265625')
4217
Georg Brandl62069d32010-07-31 08:56:11 +00004218- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4219 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00004220
Georg Brandl62069d32010-07-31 08:56:11 +00004221- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4222 InvalidOperation instead of returning False. (Comparisons involving a quiet
4223 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4224 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004225
Georg Brandl62069d32010-07-31 08:56:11 +00004226- Issue #2531: Comparison operations between floats and Decimal instances now
4227 return a result based on the numeric values of the operands; previously they
4228 returned an arbitrary result based on the relative ordering of id(float) and
4229 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4230 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004231
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004232- Added a subtract() method to collections.Counter().
4233
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004234- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004235 argument `-` which tells it to read files to compile from stdin. Each line is
4236 read on demand and the named file is compiled immediately. (Original patch by
4237 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004238
Florent Xicluna806d8cf2010-03-30 19:34:18 +00004239- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4240 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004241 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00004243- Comparisons using one of <, <=, >, >= between a complex instance and a
4244 Fractions instance now raise TypeError instead of returning True/False. This
4245 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4246 <=> complex, and complex <=> complex comparisons.

4254
Antoine Pitrou910bd512010-03-22 20:11:09 +00004255- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00004256 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Georg Brandl62069d32010-07-31 08:56:11 +00004289- The internals of the subprocess module on POSIX systems have been replaced by
4290 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4291 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004293- subprocess.Popen now has restore_signals and start_new_session features. The
4294 default of restore_signals=True is a new behavior compared to earlier Python
4295 versions. This means that signals such as SIGPIPE are not ignored by default
4296 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004551- Issue #6816: runpy now provides a run_path function that allows Python code to
4552 execute file paths that refer to source or compiled Python files as well as
4553 zipfiles, directories and other valid sys.path entries that contain a
4554 __main__.py file. This allows applications that run other Python scripts to
Nick Coghlan260bd3e2009-11-16 06:49:25 +00004555 support the same flexibility as the CPython command line itself.

Antoine Pitrou434736a2009-11-10 18:46:01 +00004572- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00004573 default when instantiating a `threading.RLock` object. This makes recursive
4574 locks as fast as regular non-recursive locks (previously, they were slower by
4575 10x to 15x).

4595 from stdin so that existing input does not confuse it and lead to incorrect
4596 entry or an IOError. It also properly flushes it afterwards to avoid the
4597 terminal echoing the input afterwards on OSes such as Solaris.

Mark Dickinsonfa41e602010-09-28 07:22:27 +00004784- Issue #9959: Tweak formula used for computing math.log of an integer,
4785 making it marginally more accurate for exact powers of 2.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004789- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004790 compared to other unix systems. In particular, os.getgroups() does not reflect
4791 any changes made using os.setgroups() but basicly always returns the same
4792 information as the id command. os.getgroups() can now return more than 16
4793 groups on MacOSX.

4798 struct.pack('>?')): if conversion to bool raised an exception then that
4799 exception wasn't properly propagated on machines where char is unsigned.

Georg Brandl62069d32010-07-31 08:56:11 +00004807- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by Jason
4808 R. Coombs.
Brian Curtind40e6f72010-07-08 21:39:08 +00004809
Benjamin Petersona9800a82010-07-07 19:04:48 +00004810- In struct.pack, correctly propogate exceptions from computing the truth of an
4811 object in the '?' format.

4814
Benjamin Petersonf751bc92010-07-02 13:46:42 +00004815- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
4816 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00004817
Georg Brandl62069d32010-07-31 08:56:11 +00004818- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4819 Prior to this change, timezone adjustment in utctimetuple() could produce
4820 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4821 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00004822
Georg Brandl62069d32010-07-31 08:56:11 +00004823- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4824 directive. When the ``%z`` directive is present in the format string, an
4825 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4826 ``datetime.timezone`` instance constructed from the parsed offset. If both
4827 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4828 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00004829
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004830- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004831 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4832 ``datetime.timezone``, return fixed name and UTC offset from their
4833 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4834 returns ``None``. A class attribute, ``utc`` contains an instance
4835 representing the UTC timezone. Original patch by Rafe Kaplan.
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004836
Georg Brandl62069d32010-07-31 08:56:11 +00004837- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
4838 includes documentation for the struct.Struct class.
Mark Dickinson4b80ef52010-06-12 15:17:02 +00004839
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00004840- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00004841 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00004842 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00004843
Georg Brandl62069d32010-07-31 08:56:11 +00004844- Issue #7384: If the system readline library is linked against ncurses, the
4845 curses module must be linked against ncurses as well. Otherwise it is not safe
4846 to load both the readline and curses modules in an application.
Stefan Kraha3ac44e2010-06-08 14:00:52 +00004847
Georg Brandl62069d32010-07-31 08:56:11 +00004848- Issue #2810: Fix cases where the Windows registry API returns ERROR_MORE_DATA,
4849 requiring a re-try in order to get the complete result.
Brian Curtin60853212010-05-26 17:43:50 +00004850
Georg Brandl62069d32010-07-31 08:56:11 +00004851- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
4852 with an improved 'binary-split' algorithm that uses fewer multiplications and
4853 allows many of the multiplications to be performed using plain C integer
4854 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
4855 arguments.
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00004856
Mark Dickinson85eacea2010-05-10 16:27:45 +00004857- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
4858 overflow checks in the audioop module.
4859
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004860- Issue #8644: The accuracy of td.total_seconds() has been improved (by
4861 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00004862 the result is now always correctly rounded, and is equivalent to ``td /
4863 timedelta(seconds=1)``.
Mark Dickinson0381e3f2010-05-08 14:35:02 +00004864
Georg Brandl62069d32010-07-31 08:56:11 +00004865- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /

4870
Mark Dickinsonc5935772010-04-03 15:54:36 +00004871- Issue #8300: When passing a non-integer argument to struct.pack with any
4872 integer format code, struct.pack first attempts to convert the non-integer
4873 using its __index__ method. If that method is non-existent or raises
4874 TypeError it goes on to try the __int__ method, as described below.
4875

5313
Eric Smith41669ca2009-05-23 14:23:22 +00005314- Issue #6089: Fixed str.format with certain invalid field specifiers
5315 that would raise SystemError.
5316
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005317- Issue #5982: staticmethod and classmethod now expose the wrapped
5318 function with __func__.
5319
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005320- Added support for multiple context managers in the same with-statement.
5321 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00005322
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005323- Issue #5829: complex("1e500") no longer raises OverflowError. This
5324 makes it consistent with float("1e500") and interpretation of real
5325 and imaginary literals.
5326
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005327- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

R. David Murraydd226ea2009-05-13 12:27:21 +00005329- Issue #5994: the marshal module now has docstrings.
5330
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005331- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5332 (1) inf and nan strings with trailing whitespace were incorrectly
5333 rejected; (2) parsing of strings representing infinities and nans
5334 was locale aware; and (3) the interpretation of fromhex('-nan')
5335 didn't match that of float('-nan').

5338-------
5339
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00005340- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
5341
R. David Murrayfb123912009-05-28 18:19:00 +00005342- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
5343
R. David Murray1f1b9d32009-05-27 20:56:59 +00005344- Issue #6121: pydoc now ignores leading and trailing spaces in the
5345 argument to the 'help' function.
5346
Georg Brandlfaf41492009-05-26 18:31:11 +00005347- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
5348 arguments for strings with a space in them.
5349
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00005350- collections.namedtuple() was not working with the following field
5351 names: cls, self, tuple, itemgetter, and property.
5352
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005353- In unittest, using a skipping decorator on a class is now equivalent to
5354 skipping every test on the class. The ClassTestSuite class has been removed.
5355
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005356- Issue #6050: Don't fail extracting a directory from a zipfile if
5357 the directory already exists.
5358
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005359- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5360 than an int, which makes some operations possible under 64-bit Linux (e.g.
5361 DN_MULTISHOT with F_NOTIFY).
5362
Antoine Pitrou716c4442009-05-23 19:04:03 +00005363- Issue #5761: Add the name of the underlying file to the repr() of various
5364 IO objects.
5365
R. David Murraycaa27b72009-05-23 18:49:56 +00005366- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5367 by Musashi Tamura, tests by Marcin Bachry.
5368
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005369- Issue #1983: Fix functions taking or returning a process identifier to use
5370 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5371 a process identifier type wider than the standard C integer type.
5372
R. David Murray87e20742009-05-23 01:30:26 +00005373- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

Antoine Pitrou2ca24f02009-05-14 21:30:46 +00005383- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
5384
Antoine Pitroue4501852009-05-14 18:55:55 +00005385- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5386 library. This means, for example, that opening an UTF-16 text file in
5387 append mode doesn't add a BOM at the end of the file if the file isn't
5388 empty.
5389
R. David Murray74b89242009-05-13 17:33:03 +00005390- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5391 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5392 corrects a pydoc regression.
5393
Georg Brandl5f90d792010-08-01 22:31:05 +00005394- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005395 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson932073a2009-05-23 16:14:33 +00005397Installation
5398------------
5399
5400- Issue #6047: fullinstall has been removed because Python 3's executable will
5401 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00005402
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00005403- Lib/smtpd.py is no longer installed as a script.

Georg Brandl5f90d792010-08-01 22:31:05 +00005427- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005428 tests on darwin even when the OS was installed on a case-sensitive
5429 filesystem. Also fixed tests that should not be run when
5430 sys.dont_write_bytecode is true.

5438Core and Builtins
5439-----------------
5440
Mark Dickinson865e01a2009-05-07 16:37:01 +00005441- Issue #5914: Add new C API function PyOS_string_to_double, and
5442 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5443
Eric Smith741191f2009-05-06 13:08:15 +00005444- Issue #3382: float.__format__, complex.__format__, and %-formatting
5445 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5446 affects nan -> NAN and inf -> INF.
5447
Mark Hammond5a607a32009-05-06 08:04:54 +00005448- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5449 in all operations, including splitdrive, split, etc. splitunc() now issues
5450 a PendingDeprecation warning.
5451
Eric Smith63376222009-05-05 14:04:18 +00005452- Issue #5920: For float.__format__, change the behavior with the
5453 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5454 to be like 'g' but with at least one decimal point and with a
5455 default precision of 12. Previously, the behavior the same but with
5456 a default precision of 6. This more closely matches str(), and
5457 reduces surprises when adding alignment flags to the empty
5458 presentation type. This also affects the new complex.__format__ in
5459 the same way.
5460
Martin v. Löwis011e8422009-05-05 04:43:17 +00005461- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5462
R. David Murrayb18500d2009-05-04 22:59:07 +00005463- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5464 shadowed by classtype's, even if it was None. property now
5465 inserts the __doc__ into the subclass instance __dict__.
5466
Antoine Pitrou244651a2009-05-04 18:56:13 +00005467- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5468 sequences. Patch by Nick Barnes and Victor Stinner.
5469
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005470- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005471
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005472- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5473 received a new method, detach(). detach() disconnects the underlying stream
5474 from the buffer or text IO and returns it.
5475
Mark Dickinson33841c32009-05-01 15:37:04 +00005476- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5477 floats with absolute value over 1e50. Also remove length
5478 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5479 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005480
Eric Smith741191f2009-05-06 13:08:15 +00005481- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005482 format(complex(1, 2./3), '.5') now produces a sensible result.
5483
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005484- Issue #5864: Fix empty format code formatting for floats so that it
5485 never gives more than the requested number of significant digits.
5486
Eric Smith6dc46f52009-04-27 20:39:49 +00005487- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5488 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5489
Eric Smithcc32a112009-04-26 21:35:14 +00005490- Issue #5835: Deprecate PyOS_ascii_formatd.
5491
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005492- Issue #4971: Fix titlecase for characters that are their own
5493 titlecase, but not their own uppercase.
5494
Benjamin Peterson193152c2009-04-25 01:08:45 +00005495- Issue #5283: Setting __class__ in __del__ caused a segfault.
5496
Mark Dickinsonad476da2009-04-23 19:14:16 +00005497- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5498 z involves nans, infs or negative zeros.
5499
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005500- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005501
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005502- Issue #1869 (and many duplicates): make round(x, n) correctly
5503 rounded for a float x, by using the decimal <-> binary conversions
5504 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5505 consistently agrees with format(x, '.2f').
5506
Benjamin Petersonae937c02009-04-18 20:54:08 +00005507- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5508 some builtin types.
5509
Eric Smith0923d1d2009-04-16 20:16:10 +00005510- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5511
Eric Smith35e84722009-04-16 20:21:28 +00005512- Issue #5515: str.format() type 'n' combined with commas and leading
5513 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005514
5515- Implement PEP 378, Format Specifier for Thousands Separator, for
5516 floats.
5517
Mark Dickinson3370cce2009-04-17 22:40:53 +00005518- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005519 1e11, not 1e12. This avoids printing 13 significant digits in
5520 situations where only 12 of them are correct. Example problem
5521 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5522 long time.)
5523
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005524- Issue #1580: On most platforms, use a 'short' float repr: for a
5525 finite float x, repr(x) now outputs a string based on the shortest
5526 sequence of decimal digits that rounds to x. Previous behaviour was
5527 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005528 Another minor difference is that the new repr switches to
5529 exponential notation at 1e16 instead of the previous 1e17; this
5530 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005531
5532 There's a new sys attribute sys.float_repr_style, which takes
5533 the value 'short' to indicate that we're using short float repr,
5534 and 'legacy' if the short float repr isn't available for one
5535 reason or another.
5536
5537 The float repr change involves incorporating David Gay's 'perfect
5538 rounding' code into the Python core (it's in Python/dtoa.c). As a
5539 secondary consequence, all string-to-float and float-to-string
5540 conversions (including all float formatting operations) will be
5541 correctly rounded on these platforms.
5542
Georg Brandl5f90d792010-08-01 22:31:05 +00005543 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005544 this change does not apply.
5545
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005546- Issue #5759: float() didn't call __float__ on str subclasses.
5547
Georg Brandlabc38772009-04-12 15:51:51 +00005548- The string.maketrans() function is deprecated; there is a new static method
5549 maketrans() on the bytes and bytearray classes. This removes confusion about
5550 the types string.maketrans() is supposed to work with, and mirrors the
5551 methods available on the str class.
5552
R. David Murraydc6da8a2009-04-09 22:16:43 +00005553- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5554 its clarity and its speed.
5555
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005556- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``

Mark Dickinsone94c6792009-02-02 20:36:42 +00005855 the type definition cmpfunc. The tp_compare slot has been renamed
5856 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00005858- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005859 were suppressing all exceptions. These include list() and bytearray().
5860
Mark Dickinson1124e712009-01-28 21:25:58 +00005861- Issue #4707: round(x, n) now returns an integer if x is an integer.
5862 Previously it returned a float.
5863
Antoine Pitroub52ec782009-01-25 16:34:23 +00005864- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5865 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5866 evaluation loop is compiled with a new dispatch mechanism which gives
5867 speedups of up to 20%, depending on the system, on various benchmarks.
5868
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005869- Issue #4874: Most builtin decoders now reject unicode input.

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00005876- Issue #4838: When a module is deallocated, free the memory backing the
5877 optional module state data.
5878
Mark Dickinson8055afd2009-01-17 10:04:45 +00005879- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005880 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005881
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005882- Issue #4935: The overflow checking code in the expandtabs() method common
5883 to str, bytes and bytearray could be optimized away by the compiler, letting
5884 the interpreter segfault instead of raising an error.
5885
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005886- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5887 __next__ method.
5888
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005889- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5890 function no longer attempt to call the __long__ slot to convert an object
5891 to an integer. Only the __int__ and __trunc__ slots are examined.

5896
Antoine Pitrouab868312009-01-10 15:40:25 +00005897- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5898 common cases are optimized thanks to a dedicated fast path and a moderate
5899 amount of loop unrolling.
5900
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005901- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5902 collecting the oldest generation) so that allocating lots of objects without
5903 destroying them does not show quadratic performance. Based on a proposal by
5904 Martin von Löwis at
5905 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5906
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005907- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005908 having been closed (for instance, a read() call could return some
5909 previously buffered data). Patch by Dmitry Vasiliev.
5910
Antoine Pitrou05608432009-01-09 18:53:14 +00005911- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5912 flag to work properly. Furthermore, when specifying -u, the text stdout
5913 and stderr streams have line-by-line buffering enabled (the default being
5914 to buffer arbitrary chunks of data).
5915
Raymond Hettinger35631532009-01-09 03:58:09 +00005916- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5917 instead of ints (reducing its size from 4 to 8 times thereby reducing
5918 Python's overall memory).
5919
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005920- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5921 an existing .py counterpart, override the co_filename attributes of all
5922 code objects if the original filename is obsolete (which can happen if the
5923 file has been renamed, moved, or if it is accessed through different paths).
5924 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5925
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005926- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5927 one byte. Also fixes the meaning of len() so that it returns the number of
5928 items, rather than the size in bytes.
5929
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005930- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5931
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005932- Issue #4747: When the terminal does not use utf-8, executing a script with
5933 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5934
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005935- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5939 did not get collected.
5940
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005941- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5942 where the tp_hash and tp_dict slots are both NULL.
5943
Georg Brandlccc47b62008-12-28 11:44:14 +00005944- Issue #4759: None is now allowed as the first argument of
5945 bytearray.translate(). It was always allowed for bytes.translate().
5946
Skip Montanaro80072cb2008-12-23 03:51:14 +00005947- Added test case to ensure attempts to read from a file opened for writing
5948 fail.
5949
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005950- Issue #3106: Speedup some comparisons (str/str and int/int).

5954
Antoine Pitrou621601a2008-12-17 23:18:19 +00005955- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5957 unreachable. Original patch by Neil Schemenauer.
5958
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005959- Issue #3439: Add a bit_length method to int.
5960
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005961- Issue #2173: When getting device encoding, check that return value of
5962 nl_langinfo is not the empty string. This was causing silent build
5963 failures on OS X.
5964
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005965- Issue #4597: Fixed several opcodes that weren't always propagating
5966 exceptions.
5967
5968- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005969 context manager returns a value that cannot be converted to a bool.
5970
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005971- Issue #4445: Replace "sizeof(PyBytesObject)" with
5972 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5973 bytes instances. On a typical machine this saves 3 bytes of memory
5974 (on average) per allocation of a bytes instance.
5975
Christian Heimesa872de52008-12-05 08:26:55 +00005976- Issue #4533: File read operation was dreadfully slow due to a slowly
5977 growing read buffer. Fixed by using the same growth rate algorithm as
5978 Python 2.x.
5979
Antoine Pitrou5504e892008-12-06 21:27:53 +00005980- Issue #4509: Various issues surrounding resize of bytearray objects to
5981 which there are buffer exports (e.g. memoryview instances).
5982
Georg Brandlf9734072008-12-07 15:30:06 +00005983- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5984 method on file objects with closefd=False. The file descriptor is still
5985 kept open but the file object behaves like a closed file. The ``FileIO``
5986 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00005987
Antoine Pitroubc420402008-12-07 20:14:49 +00005988- Issue #4569: Interpreter crash when mutating a memoryview with an item size

5994
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005995- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5996 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5997 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5998 of using the replace error handler in PyUnicode_DecodeUTF8().
