Victor Stinner4ee65a92011-01-22 10:30:29 +0000311 filenames, at bootstrap, if the codec registry is not ready yet. It is still
312 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)

322
Armin Ronacher8d96d772011-01-22 13:13:05 +0000323- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
324 encoding. This is the preferred encoding of PEP 3333 and the base encoding
325 of HTTP 1.1.
326
Armin Ronacher59531282011-01-22 13:44:22 +0000327- To match the behaviour of HTTP server, the HTTP client library now also
328 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
329 that for incoming headers which makes this behaviour now consistent in
330 both incoming and outgoing direction.

Georg Brandl255abdd2011-01-16 14:17:26 +0000421 continuation line in the formatted value has no leading white space and looks
422 like a header. Since Generator uses Header to format all headers, this check
423 is made for all headers in any serialized message at serialization time. This
424 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000425
Antoine Pitrou67b212e2011-01-08 09:55:31 +0000426- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Georg Brandl255abdd2011-01-16 14:17:26 +0000433 non-ASCII bytes (parsed by a Bytes Parser) when doing conversion to 7bit-clean
434 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +0000435
R. David Murray6f0022d2011-01-07 21:57:25 +0000436- email.header.Header was incorrectly encoding folding white space when
Georg Brandl255abdd2011-01-16 14:17:26 +0000437 rfc2047-encoding header values with embedded newlines, leaving them without
438 folding whitespace. It now uses the continuation_ws, as it does for
439 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +0000441- Issue #1777412, #10827: Changed the rules for 2-digit years. The
442 time.asctime(), time.ctime() and time.strftime() functions will now format
443 any year when ``time.accept2dyear`` is False and will accept years >= 1000
444 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
445 supported by the OS. With Visual Studio or on Solaris, the year is limited to
446 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

1417
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00001418- Issue #10068: Global objects which have reference cycles with their module's
1419 dict are now cleared again. This causes issue #7140 to appear again.
1420
Victor Stinner257d38f2010-10-09 10:12:11 +00001421- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00001422 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00001423
Georg Brandl27a28582010-10-10 09:49:21 +00001424- ast.literal_eval() can now handle negative numbers. It is also a little more
1425 liberal in what it accepts without compromising the safety of the evaluation.
1426 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00001427
Benjamin Peterson970d1882010-10-02 17:55:47 +00001428- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
1429 result metaclasses can now be ABCs (see #9533).
1430
Victor Stinneraef57e32010-10-02 11:50:49 +00001431- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
1432
Victor Stinner5593d8a2010-10-02 11:11:27 +00001433- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00001434 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
1435 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00001436
Brian Curtin9e88b5a2010-10-01 14:49:24 +00001437- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00001438 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00001439
Victor Stinner137c34c2010-09-29 10:25:54 +00001440- Issue #9979: Create function PyUnicode_AsWideCharString().
1441
Brett Cannon5305a992010-09-27 21:08:38 +00001442- Issue #7397: Mention that importlib.import_module() is probably what someone
1443 really wants to be using in __import__'s docstring.
1444
Georg Brandl27a28582010-10-10 09:49:21 +00001445- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
1446 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00001447
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001448- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00001449 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00001450
Brian Curtine8e4b3b2010-09-23 20:04:14 +00001451- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
1452
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00001453- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
1454 threads are still running. Instead, reinitialize the GIL on a second call to
1455 Py_Initialize().
1456
Georg Brandl27a28582010-10-10 09:49:21 +00001457- All SyntaxErrors now have a column offset and therefore a caret when the error
1458 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00001459
Brett Cannonbc2eff32010-09-19 21:39:02 +00001460- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
1461 module that was imported, but instead gets the module from sys.modules.
1462
Nick Coghlan37ee8502010-12-03 14:26:13 +00001463- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00001464 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00001465
Georg Brandl27a28582010-10-10 09:49:21 +00001466- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1467 with a non-empty format string. This is an effort to future-proof user
1468 code. If a derived class does not currently implement __format__ but later
1469 adds its own __format__, it would most likely break user code that had
1470 supplied a format string. This will be changed to a DeprecationWaring in
1471 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00001472
Antoine Pitrou1df15362010-09-13 14:16:46 +00001473- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
1474 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
1475 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
1476
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00001477- Issue #9210: Configure option --with-wctype-functions was removed. Using the
1478 functions from the libc caused the methods .upper() and lower() to become
1479 locale aware and created subtly wrong results.
1480
Georg Brandl27a28582010-10-10 09:49:21 +00001481- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
1482 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00001483
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001484- Issue #4617: Previously it was illegal to delete a name from the local
1485 namespace if it occurs as a free variable in a nested block. This limitation
1486 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1487
Georg Brandl27a28582010-10-10 09:49:21 +00001488- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1489 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1490 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1491 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00001492
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00001493- Issue #9757: memoryview objects get a release() method to release the
1494 underlying buffer (previously this was only done when deallocating the
1495 memoryview), and gain support for the context management protocol.
1496
Antoine Pitrou079ce542010-09-08 12:37:10 +00001497- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
1498 thread-local storage key.

1508
1509- Issue #1718574: Fix options that were supposed to accept arguments but did
1510 not in build_clib.
1511
Antoine Pitroudbec7802010-10-10 09:37:12 +00001512- Issue #9437: Fix building C extensions with non-default LDFLAGS.
1513
R. David Murray96fd54e2010-10-08 15:55:28 +00001514- Issue #4661: email can now parse bytes input and generate either converted
1515 7bit output or bytes output. Email version bumped to 5.1.0.
1516
Antoine Pitrou59fdd672010-10-08 10:37:08 +00001517- Issue #1589: Add ssl.match_hostname(), to help implement server identity
1518 verification for higher-level protocols.
1519
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00001520- Issue #9759: GzipFile now raises ValueError when an operation is attempted
1521 after the file is closed. Patch by Jeffrey Finkelstein.
1522
Éric Araujo6108bf52010-10-04 23:52:37 +00001523- Issue #9042: Fix interaction of custom translation classes and caching in
1524 gettext.
1525
Éric Araujoef777bd2010-10-05 00:04:20 +00001526- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001527 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001528 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001529 replacement for old handle_accept() and avoids the user to call accept()
1530 directly.
1531
Lars Gustäbel331b8002010-10-04 15:18:47 +00001532- Issue #9065: tarfile no longer uses "root" as the default for the uname and
1533 gname field.
1534
Georg Brandl27a28582010-10-10 09:49:21 +00001535- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
1536 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00001537
R. David Murray5397e862010-10-02 15:58:26 +00001538- Issue #1050268: parseaddr now correctly quotes double quote and backslash
1539 characters that appear inside quoted strings in email addresses.
1540
Georg Brandl27a28582010-10-10 09:49:21 +00001541- Issue #10004: quoprimime no longer generates a traceback when confronted with
1542 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00001543
Georg Brandl27a28582010-10-10 09:49:21 +00001544- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
1545 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00001546
Georg Brandl27a28582010-10-10 09:49:21 +00001547- Issue #9360: Cleanup and improvements to the nntplib module. The API now
1548 conforms to the philosophy of bytes and unicode separation in Python 3. A
1549 test suite has also been added.

Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00001551- Issue #9962: GzipFile now has the peek() method.
1552
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001553- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00001554 retry the select() loop instead of bailing out. This is because select() can
1555 incorrectly report a socket as ready for reading (for example, if it received
1556 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00001557
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00001558- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)

Antoine Pitrou6d7df632010-09-27 17:52:25 +00001560- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00001561 received. Now sendall() properly calls signal handlers if necessary, and
1562 retries sending if these returned successfully, including on sockets with a
1563 timeout.

1601
Antoine Pitrou98b46702010-09-18 22:59:00 +00001602- Issue #9854: SocketIO objects now observe the RawIOBase interface in
Georg Brandl27a28582010-10-10 09:49:21 +00001603 non-blocking mode: they return None when an operation would block (instead of
1604 raising an exception).
Antoine Pitrou98b46702010-09-18 22:59:00 +00001605
Amaury Forgeot d'Arcd61d0772010-09-17 23:27:09 +00001606- Issue #1730136: Fix the comparison between a tk.font.Font and an object of

Antoine Pitrou328ec742010-09-14 18:37:24 +00001615
Georg Brandl27a28582010-10-10 09:49:21 +00001616- Issue #1552: socket.socketpair() now returns regular socket.socket objects

Raymond Hettingerfa11db02010-09-12 04:12:42 +00001636- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001637 it possible for the user to create self-referencing ordered dictionaries which
1638 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001639 approach of using weakref proxies so that reference cycles never get created
1640 in the first place.
1641
Victor Stinnercb043522010-09-10 23:49:04 +00001642- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
1643 encode the value with filesystem encoding and surrogateescape (instead of
Georg Brandl27a28582010-10-10 09:49:21 +00001644 utf-8 in strict mode) . Patch written by David Watson.
Victor Stinnercb043522010-09-10 23:49:04 +00001645
Georg Brandl27a28582010-10-10 09:49:21 +00001646- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
1647 environment variable to set the filesystem encoding at Python startup.
1648 sys.setfilesystemencoding() creates inconsistencies because it is unable to
1649 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00001650
Georg Brandl27a28582010-10-10 09:49:21 +00001651- Issue #9410: Various optimizations to the pickle module, leading to speedups

Vinay Sajip121a1c42010-09-08 10:46:15 +00001658- Logging: Added QueueHandler class to facilitate logging usage with
1659 multiprocessing.
1660
Georg Brandl27a28582010-10-10 09:49:21 +00001661- Issue #9707: Rewritten reference implementation of threading.local which is
1662 friendlier towards reference cycles. This change is not normally visible
1663 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00001664
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00001665- Issue #6394: os.getppid() is now supported on Windows. Note that it will
1666 still return the id of the parent process after it has exited. This process
1667 id may even have been reused by another unrelated process.
1668
Georg Brandl27a28582010-10-10 09:49:21 +00001669- Issue #9792: In case of connection failure, socket.create_connection() would
1670 swallow the exception and raise a new one, making it impossible to fetch the
1671 original errno, or to filter timeout errors. Now the original error is
1672 re-raised.
Antoine Pitrou4b92b5f2010-09-07 21:05:49 +00001673
Georg Brandl27a28582010-10-10 09:49:21 +00001674- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
1675 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
1676 back after the system call. Original patch by Brian Brazil.
Antoine Pitrou5e38aae2010-09-07 16:30:09 +00001677
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00001678- Updates to the random module:
1679
Georg Brandl27a28582010-10-10 09:49:21 +00001680 * Document which parts of the module are guaranteed to stay the same across

Georg Brandl27a28582010-10-10 09:49:21 +00001683 * Update the seed() method to use all of the bits in a string instead of just
1684 the hash value. This makes better use of the seed value and assures the
1685 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00001687 * Improved the random()-->integer algorithm used in choice(), shuffle(),
1688 sample(), randrange(), and randint(). Formerly, it used int(n*random())
1689 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00001690
1691 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00001710- hashlib has two new constant attributes: algorithms_guaranteed and
1711 algorithms_avaiable that respectively list the names of hash algorithms
1712 guaranteed to exist in all Python implementations and the names of hash
1713 algorithms available in the current process.
1714

Georg Brandl62069d32010-07-31 08:56:11 +00002226 start byte and the continuation byte(s) are now considered invalid, instead of
2227 the number of bytes specified by the start byte. E.g.:
2228 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2229 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2230 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2231 returned a single u'\ufffd'.

2276 the 'L' code (for long long). (All other integer codes already raise
2277 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00002287 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects

2304 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00002305 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
2306 (2) The comparison raised an OverflowError for large integers, leading to
2307 unpredictable exceptions when combining integers and complex objects in sets
2308 or dicts.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00002610- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
2611 variable argument list. `Py_VA_COPY` is equivalent to C99
2612 `va_copy`, but available on all python platforms.
2613
Mark Dickinsone6fc7402010-08-06 18:55:26 +00002614- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
2615 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
2616 "step = -step" when reversing a slice.
2617
Georg Brandl62069d32010-07-31 08:56:11 +00002618- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the

Antoine Pitrou8689a102010-04-01 16:53:15 +00002626- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00002627 function declaration, which was kept for backwards compatibility reasons, is
2628 now removed (the macro was introduced in 1997!).

2638 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
2639 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00002640 to match the behaviour of the other integer format codes.
2641

Georg Brandl62069d32010-07-31 08:56:11 +00002650- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
2651 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
2652 accessing the d_type and d_name members of structures using PyDescr_COMMON.

2666
Georg Brandl62069d32010-07-31 08:56:11 +00002667- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2668 allocator will be automatically disabled when running under Valgrind. This
2669 gives improved memory leak detection when running under Valgrind, while taking
2670 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00002747 applications that use a lot of regular expressions and limits the impact of
2748 the performance hit anytime the cache is exceeded.

2761 module is renamed to `_datetime` and if available, overrides all classes
2762 defined in datetime with fast C impementation. Python implementation is based
2763 on the original python prototype for the datetime module by Tim Peters with
2764 minor modifications by the PyPy project. The test suite now tests `datetime`
2765 module with and without `_datetime` acceleration using the same test cases.

2980 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
2981 file system encoding with the surrogateescape error handler (instead of
2982 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

2985
Georg Brandl62069d32010-07-31 08:56:11 +00002986- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
2987 messages when accessing undefined class attributes because of the cheap
2988 inheritance with the underlying socket object. The cheap inheritance has been
2989 deprecated.

2992 Patch by Tres Seaver.
2993
Victor Stinnerd17f2192010-08-15 09:56:07 +00002994- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00002995 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00003002- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3003 operation raises multiple signals and more than one of those signals is
3004 trapped, the specification determines the order in which the signals should be
3005 handled. In many cases this order wasn't being followed, leading to the wrong
3006 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00003040- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3041 the method could block indefinitely if called just before the event loop
3042 started running. This also fixes the occasional freezes witnessed in
3043 test_httpservers.

Georg Brandl62069d32010-07-31 08:56:11 +00003045- Issue #8524: When creating an SSL socket, the timeout value of the original
3046 socket wasn't retained (instead, a socket with a positive timeout would be
3047 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00003048
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00003049- Issue #5103: SSL handshake would ignore the socket timeout and block
3050 indefinitely if the other end didn't respond.
3051
Georg Brandl62069d32010-07-31 08:56:11 +00003052- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00003064- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3065 string "python" as the *ident*. openlog() arguments are all optional and
3066 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00003067
Georg Brandl62069d32010-07-31 08:56:11 +00003068- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
3069 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00003070 wanting to continue using the socket in clear-text mode, by disabling

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00003121 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00003122 relies on the system threading library, so as to avoid a semi-busy wait loop.

3158 InvalidOperation instead of returning False. (Comparisons involving a quiet
3159 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3160 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00003162- Issue #2531: Comparison operations between floats and Decimal instances now
3163 return a result based on the numeric values of the operands; previously they
3164 returned an arbitrary result based on the relative ordering of id(float) and
3165 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3166 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003170- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003171 argument `-` which tells it to read files to compile from stdin. Each line is

3180 Fractions instance now raise TypeError instead of returning True/False. This
3181 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3182 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003726 compared to other unix systems. In particular, os.getgroups() does not reflect

3729 groups on MacOSX.

3768 ``datetime.timezone``, return fixed name and UTC offset from their
3769 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always

Georg Brandl62069d32010-07-31 08:56:11 +00003798 the result is now always correctly rounded, and is equivalent to ``td /

Antoine Pitroue4501852009-05-14 18:55:55 +00004321- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
4322 library. This means, for example, that opening an UTF-16 text file in
4323 append mode doesn't add a BOM at the end of the file if the file isn't

Mark Dickinson865e01a2009-05-07 16:37:01 +00004377- Issue #5914: Add new C API function PyOS_string_to_double, and
4378 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4379
Eric Smith741191f2009-05-06 13:08:15 +00004380- Issue #3382: float.__format__, complex.__format__, and %-formatting
4381 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

4383
Mark Hammond5a607a32009-05-06 08:04:54 +00004384- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4385 in all operations, including splitdrive, split, etc. splitunc() now issues
4386 a PendingDeprecation warning.
4387
Eric Smith63376222009-05-05 14:04:18 +00004388- Issue #5920: For float.__format__, change the behavior with the
4389 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4390 to be like 'g' but with at least one decimal point and with a
4391 default precision of 12. Previously, the behavior the same but with
4392 a default precision of 6. This more closely matches str(), and
4393 reduces surprises when adding alignment flags to the empty
4394 presentation type. This also affects the new complex.__format__ in
4395 the same way.
4396
Martin v. Löwis011e8422009-05-05 04:43:17 +00004397- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00004399- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4400 shadowed by classtype's, even if it was None. property now
4401 inserts the __doc__ into the subclass instance __dict__.
4402

4405
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004406- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004407
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004408- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4409 received a new method, detach(). detach() disconnects the underlying stream
4410 from the buffer or text IO and returns it.
4411
Mark Dickinson33841c32009-05-01 15:37:04 +00004412- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4413 floats with absolute value over 1e50. Also remove length
4414 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4415 12.34 no longer raise an exception.

Eric Smith58a42242009-04-30 01:00:33 +00004418 format(complex(1, 2./3), '.5') now produces a sensible result.
4419

4421 never gives more than the requested number of significant digits.
4422
Eric Smith6dc46f52009-04-27 20:39:49 +00004423- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00004433- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4434 z involves nans, infs or negative zeros.
4435
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004436- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004437
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004438- Issue #1869 (and many duplicates): make round(x, n) correctly
4439 rounded for a float x, by using the decimal <-> binary conversions
4440 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4441 consistently agrees with format(x, '.2f').
4442
Benjamin Petersonae937c02009-04-18 20:54:08 +00004443- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith35e84722009-04-16 20:21:28 +00004448- Issue #5515: str.format() type 'n' combined with commas and leading
4449 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004450
4451- Implement PEP 378, Format Specifier for Thousands Separator, for
4452 floats.
4453
Mark Dickinson3370cce2009-04-17 22:40:53 +00004454- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004455 1e11, not 1e12. This avoids printing 13 significant digits in
4456 situations where only 12 of them are correct. Example problem
4457 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4458 long time.)
4459
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004460- Issue #1580: On most platforms, use a 'short' float repr: for a
4461 finite float x, repr(x) now outputs a string based on the shortest
4462 sequence of decimal digits that rounds to x. Previous behaviour was
4463 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004464 Another minor difference is that the new repr switches to
4465 exponential notation at 1e16 instead of the previous 1e17; this
4466 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004467
4468 There's a new sys attribute sys.float_repr_style, which takes
4469 the value 'short' to indicate that we're using short float repr,
4470 and 'legacy' if the short float repr isn't available for one
4471 reason or another.
4472
4473 The float repr change involves incorporating David Gay's 'perfect
4474 rounding' code into the Python core (it's in Python/dtoa.c). As a
4475 secondary consequence, all string-to-float and float-to-string
4476 conversions (including all float formatting operations) will be
4477 correctly rounded on these platforms.
4478
Georg Brandl5f90d792010-08-01 22:31:05 +00004479 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004480 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004482- Issue #5759: float() didn't call __float__ on str subclasses.
4483
Georg Brandlabc38772009-04-12 15:51:51 +00004484- The string.maketrans() function is deprecated; there is a new static method
4485 maketrans() on the bytes and bytearray classes. This removes confusion about
4486 the types string.maketrans() is supposed to work with, and mirrors the
4487 methods available on the str class.
4488
R. David Murraydc6da8a2009-04-09 22:16:43 +00004489- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsonb40b9472009-03-29 16:58:21 +00004752 struct.error instead of returning b'\xff\xff\xff\xff'. The
4753 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
4754 have been removed from the struct module.

4780
Mark Dickinson87ec0852009-02-09 17:15:59 +00004781- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
4782 it now forces its argument to double before testing for infinity.
4783
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00004784- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00004793
Georg Brandl1cdd83c2009-04-05 20:24:29 +00004794- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00004795 were suppressing all exceptions. These include list() and bytearray().

4799
Antoine Pitroub52ec782009-01-25 16:34:23 +00004800- Issue #4753: By enabling a configure option named '--with-computed-gotos'
4801 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
4802 evaluation loop is compiled with a new dispatch mechanism which gives
4803 speedups of up to 20%, depending on the system, on various benchmarks.
4804
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00004805- Issue #4874: Most builtin decoders now reject unicode input.

4813 optional module state data.
4814
Mark Dickinson8055afd2009-01-17 10:04:45 +00004815- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004816 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00004817
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00004818- Issue #4935: The overflow checking code in the expandtabs() method common
4819 to str, bytes and bytearray could be optimized away by the compiler, letting
4820 the interpreter segfault instead of raising an error.
4821
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00004822- Issue #3720: Fix a crash when an iterator modifies its class and removes its
4823 __next__ method.
4824
Mark Dickinsone5e298f2009-01-12 20:49:19 +00004825- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
4826 function no longer attempt to call the __long__ slot to convert an object
4827 to an integer. Only the __int__ and __trunc__ slots are examined.
4828
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00004829- Issue #4893: Use NT threading on CE.
4830

4832
Antoine Pitrouab868312009-01-10 15:40:25 +00004833- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
4834 common cases are optimized thanks to a dedicated fast path and a moderate
4835 amount of loop unrolling.
4836
Antoine Pitrou14b78f52009-01-09 22:27:08 +00004837- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
4838 collecting the oldest generation) so that allocating lots of objects without
4839 destroying them does not show quadratic performance. Based on a proposal by
4840 Martin von Löwis at
4841 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
4842
Vinay Sajip6268cbc2009-01-21 00:19:28 +00004843- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00004844 having been closed (for instance, a read() call could return some
4845 previously buffered data). Patch by Dmitry Vasiliev.
4846
Antoine Pitrou05608432009-01-09 18:53:14 +00004847- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
4848 flag to work properly. Furthermore, when specifying -u, the text stdout
4849 and stderr streams have line-by-line buffering enabled (the default being
4850 to buffer arbitrary chunks of data).
4851
Raymond Hettinger35631532009-01-09 03:58:09 +00004852- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
4853 instead of ints (reducing its size from 4 to 8 times thereby reducing
4854 Python's overall memory).
4855
Antoine Pitroud35cbf62009-01-06 19:02:24 +00004856- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
4857 an existing .py counterpart, override the co_filename attributes of all
4858 code objects if the original filename is obsolete (which can happen if the
4859 file has been renamed, moved, or if it is accessed through different paths).
4860 Patch by Ziga Seilnacht and Jean-Paul Calderone.
4861
Antoine Pitrouc3b39242009-01-03 16:59:18 +00004862- Issue #4580: Fix slicing of memoryviews when the item size is greater than
4863 one byte. Also fixes the meaning of len() so that it returns the number of
4864 items, rather than the size in bytes.
4865
Martin v. Löwis5c88d812009-01-02 20:47:48 +00004866- Issue #4075: Use OutputDebugStringW in Py_FatalError.
4867
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00004868- Issue #4747: When the terminal does not use utf-8, executing a script with
4869 non-ascii characters in its name could fail with a "SyntaxError: None" error.
4870
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004871- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
4872 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00004873
Antoine Pitrou7ddda782009-01-01 15:35:33 +00004874- Issue #3680: Reference cycles created through a dict, set or deque iterator
4875 did not get collected.
4876
Nick Coghlanf1f2f682008-12-30 07:29:12 +00004877- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
4878 where the tp_hash and tp_dict slots are both NULL.
4879
Georg Brandlccc47b62008-12-28 11:44:14 +00004880- Issue #4759: None is now allowed as the first argument of
4881 bytearray.translate(). It was always allowed for bytes.translate().
4882
Skip Montanaro80072cb2008-12-23 03:51:14 +00004883- Added test case to ensure attempts to read from a file opened for writing
4884 fail.
4885
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00004886- Issue #3106: Speedup some comparisons (str/str and int/int).

4896
Mark Dickinsonda2706b2008-12-11 18:03:03 +00004897- Issue #2173: When getting device encoding, check that return value of
4898 nl_langinfo is not the empty string. This was causing silent build
4899 failures on OS X.
4900
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00004901- Issue #4597: Fixed several opcodes that weren't always propagating
4902 exceptions.
4903
4904- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00004905 context manager returns a value that cannot be converted to a bool.
4906
Mark Dickinsonfd24b322008-12-06 15:33:31 +00004907- Issue #4445: Replace "sizeof(PyBytesObject)" with
4908 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
4909 bytes instances. On a typical machine this saves 3 bytes of memory
4910 (on average) per allocation of a bytes instance.
4911
Christian Heimesa872de52008-12-05 08:26:55 +00004912- Issue #4533: File read operation was dreadfully slow due to a slowly
4913 growing read buffer. Fixed by using the same growth rate algorithm as
4914 Python 2.x.
4915
Antoine Pitrou5504e892008-12-06 21:27:53 +00004916- Issue #4509: Various issues surrounding resize of bytearray objects to
4917 which there are buffer exports (e.g. memoryview instances).
4918
Georg Brandlf9734072008-12-07 15:30:06 +00004919- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
4920 method on file objects with closefd=False. The file descriptor is still
4921 kept open but the file object behaves like a closed file. The ``FileIO``
4922 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00004923
Antoine Pitroubc420402008-12-07 20:14:49 +00004924- Issue #4569: Interpreter crash when mutating a memoryview with an item size
4925 larger than 1.

4930
Walter Dörwaldc1651a02009-05-03 22:55:55 +00004931- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
4932 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4933 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4934 of using the replace error handler in PyUnicode_DecodeUTF8().
