Ned Deily657b2de2011-06-28 19:51:30 -0700605- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
606 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
607 interpreter process. This could cause failures in non-Distutils subprocesses
608 and was unreliable since tests or user programs could modify the interpreter
609 environment after Distutils set it. Instead, have Distutils set the the
610 deployment target only in the environment of each build subprocess. It is
611 still possible to globally override the default by setting
612 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
613 greater or equal to the default value, the value with which the interpreter
614 was built.

1458 provides protection against header injection attacks.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002111 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002112 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002113 encoding and to encode command line arguments on this OS.

2455-----------------
2456
Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002457- Issue #10068: Global objects which have reference cycles with their module's
2458 dict are now cleared again. This causes issue #7140 to appear again.
2459
Victor Stinner257d38f2010-10-09 10:12:11 +00002460- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002461 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002462
Georg Brandl27a28582010-10-10 09:49:21 +00002463- ast.literal_eval() can now handle negative numbers. It is also a little more
2464 liberal in what it accepts without compromising the safety of the evaluation.
2465 For example, 3j+4 and 3+4+5 are both accepted.
Raymond Hettingerbc959732010-10-08 00:47:45 +00002466
Benjamin Peterson970d1882010-10-02 17:55:47 +00002467- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2468 result metaclasses can now be ABCs (see #9533).
2469
Victor Stinneraef57e32010-10-02 11:50:49 +00002470- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2471
Victor Stinner5593d8a2010-10-02 11:11:27 +00002472- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002473 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
2474 32 bits wchar_t (eg. Linux in narrow build).
Victor Stinner5593d8a2010-10-02 11:11:27 +00002475
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002476- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
Victor Stinner5593d8a2010-10-02 11:11:27 +00002477 introduced by issue #9324.
Brian Curtin9e88b5a2010-10-01 14:49:24 +00002478
Victor Stinner137c34c2010-09-29 10:25:54 +00002479- Issue #9979: Create function PyUnicode_AsWideCharString().
2480
Brett Cannon5305a992010-09-27 21:08:38 +00002481- Issue #7397: Mention that importlib.import_module() is probably what someone
2482 really wants to be using in __import__'s docstring.
2483
Georg Brandl27a28582010-10-10 09:49:21 +00002484- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2485 to use named arguments.
Brian Curtin1771b542010-09-27 17:56:36 +00002486
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002487- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002488 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002489
Brian Curtine8e4b3b2010-09-23 20:04:14 +00002490- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2491
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002492- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2493 threads are still running. Instead, reinitialize the GIL on a second call to
2494 Py_Initialize().
2495
Georg Brandl27a28582010-10-10 09:49:21 +00002496- All SyntaxErrors now have a column offset and therefore a caret when the error
2497 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002498
Brett Cannonbc2eff32010-09-19 21:39:02 +00002499- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2500 module that was imported, but instead gets the module from sys.modules.
2501
Nick Coghlan37ee8502010-12-03 14:26:13 +00002502- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002503 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002504
Georg Brandl27a28582010-10-10 09:49:21 +00002505- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2506 with a non-empty format string. This is an effort to future-proof user
2507 code. If a derived class does not currently implement __format__ but later
2508 adds its own __format__, it would most likely break user code that had
2509 supplied a format string. This will be changed to a DeprecationWaring in
2510 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002511
Antoine Pitrou1df15362010-09-13 14:16:46 +00002512- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2513 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2514 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2515
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002516- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2517 functions from the libc caused the methods .upper() and lower() to become
2518 locale aware and created subtly wrong results.
2519
Georg Brandl27a28582010-10-10 09:49:21 +00002520- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2521 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002522
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002523- Issue #4617: Previously it was illegal to delete a name from the local
2524 namespace if it occurs as a free variable in a nested block. This limitation
2525 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2526
Georg Brandl27a28582010-10-10 09:49:21 +00002527- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2528 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2529 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2530 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002531
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002532- Issue #9757: memoryview objects get a release() method to release the
2533 underlying buffer (previously this was only done when deallocating the
2534 memoryview), and gain support for the context management protocol.
2535
Antoine Pitrou079ce542010-09-08 12:37:10 +00002536- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2537 thread-local storage key.
2538

2541
Éric Araujo0cfba092010-11-08 21:48:23 +00002542- Issue #2236: distutils' mkpath ignored the mode parameter.
2543
Éric Araujoe7cf9542010-11-06 15:01:07 +00002544- Fix typo in one sdist option (medata-check).
2545
2546- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
2547
2548- Issue #1718574: Fix options that were supposed to accept arguments but did
2549 not in build_clib.
2550
Antoine Pitroudbec7802010-10-10 09:37:12 +00002551- Issue #9437: Fix building C extensions with non-default LDFLAGS.
2552
R. David Murray96fd54e2010-10-08 15:55:28 +00002553- Issue #4661: email can now parse bytes input and generate either converted
2554 7bit output or bytes output. Email version bumped to 5.1.0.
2555
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002556- Issue #1589: Add ssl.match_hostname(), to help implement server identity
2557 verification for higher-level protocols.
2558
Antoine Pitrou7980eaa2010-10-06 21:21:18 +00002559- Issue #9759: GzipFile now raises ValueError when an operation is attempted
2560 after the file is closed. Patch by Jeffrey Finkelstein.
2561
Éric Araujo6108bf52010-10-04 23:52:37 +00002562- Issue #9042: Fix interaction of custom translation classes and caching in
2563 gettext.
2564
Éric Araujoef777bd2010-10-05 00:04:20 +00002565- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002566 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002567 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002568 replacement for old handle_accept() and avoids the user to call accept()
2569 directly.
2570
Lars Gustäbel331b8002010-10-04 15:18:47 +00002571- Issue #9065: tarfile no longer uses "root" as the default for the uname and
2572 gname field.

Georg Brandl27a28582010-10-10 09:49:21 +00002574- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
2575 an environment that does not have docutils. Patch by Arfrever.
Tarek Ziadé4bcceef2010-10-03 14:18:09 +00002576
R. David Murray5397e862010-10-02 15:58:26 +00002577- Issue #1050268: parseaddr now correctly quotes double quote and backslash
2578 characters that appear inside quoted strings in email addresses.
2579
Georg Brandl27a28582010-10-10 09:49:21 +00002580- Issue #10004: quoprimime no longer generates a traceback when confronted with
2581 invalid characters after '=' in a Q-encoded word.
R. David Murray31e984c2010-10-01 15:40:20 +00002582
Georg Brandl27a28582010-10-10 09:49:21 +00002583- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
2584 sending a 200 OK for the Expect: 100-continue request header.
Senthil Kumaran0f476d42010-09-30 06:09:18 +00002585
Georg Brandl27a28582010-10-10 09:49:21 +00002586- Issue #9360: Cleanup and improvements to the nntplib module. The API now
2587 conforms to the philosophy of bytes and unicode separation in Python 3. A
2588 test suite has also been added.
Antoine Pitrou69ab9512010-09-29 15:03:40 +00002589
Antoine Pitrouc3ed2e72010-09-29 10:49:46 +00002590- Issue #9962: GzipFile now has the peek() method.
2591
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002592- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002593 retry the select() loop instead of bailing out. This is because select() can
2594 incorrectly report a socket as ready for reading (for example, if it received
2595 some data with an invalid checksum).
Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002596
Hirokazu Yamamotocc868d42010-09-28 21:08:38 +00002597- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
2598
Antoine Pitrou6d7df632010-09-27 17:52:25 +00002599- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
Georg Brandl27a28582010-10-10 09:49:21 +00002600 received. Now sendall() properly calls signal handlers if necessary, and
2601 retries sending if these returned successfully, including on sockets with a
2602 timeout.

2630 object, only munmap().
2631
Georg Brandl27a28582010-10-10 09:49:21 +00002632- logging: Changed LoggerAdapter implementation internally, to make it easier to
2633 subclass in a useful way.
Vinay Sajip212b5902010-09-21 11:31:32 +00002634
Vinay Sajipc84f0162010-09-21 11:25:39 +00002635- logging: hasHandlers method was added to Logger, and isEnabledFor,

Georg Brandl27a28582010-10-10 09:49:21 +00002642 non-blocking mode: they return None when an operation would block (instead of

Georg Brandl27a28582010-10-10 09:49:21 +00002655- Issue #1552: socket.socketpair() now returns regular socket.socket objects

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002675- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002676 it possible for the user to create self-referencing ordered dictionaries which
2677 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002678 approach of using weakref proxies so that reference cycles never get created
2679 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00002685- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2686 environment variable to set the filesystem encoding at Python startup.
2687 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2688 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00002690- Issue #9410: Various optimizations to the pickle module, leading to speedups
2691 up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
2692 initial patch by Alexandre Vassalotti.
Antoine Pitrouea99c5c2010-09-09 18:33:21 +00002693
Georg Brandl27a28582010-10-10 09:49:21 +00002694- The pprint module now supports printing OrderedDicts in their given order
2695 (formerly, it would sort the keys).

Vinay Sajip121a1c42010-09-08 10:46:15 +00002697- Logging: Added QueueHandler class to facilitate logging usage with
2698 multiprocessing.
2699
Georg Brandl27a28582010-10-10 09:49:21 +00002700- Issue #9707: Rewritten reference implementation of threading.local which is
2701 friendlier towards reference cycles. This change is not normally visible
2702 since an optimized C implementation (_thread._local) is used instead.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002704- Issue #6394: os.getppid() is now supported on Windows. Note that it will
2705 still return the id of the parent process after it has exited. This process
2706 id may even have been reused by another unrelated process.
2707
Georg Brandl27a28582010-10-10 09:49:21 +00002708- Issue #9792: In case of connection failure, socket.create_connection() would
2709 swallow the exception and raise a new one, making it impossible to fetch the
2710 original errno, or to filter timeout errors. Now the original error is
2711 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00002713- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
2714 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
2715 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002717- Updates to the random module:
2718
Georg Brandl27a28582010-10-10 09:49:21 +00002719 * Document which parts of the module are guaranteed to stay the same across
2720 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00002722 * Update the seed() method to use all of the bits in a string instead of just
2723 the hash value. This makes better use of the seed value and assures the
2724 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002725
Georg Brandl27a28582010-10-10 09:49:21 +00002726 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2727 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2728 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002729
2730 * Improved documentation of arguments to randrange(). Issue #9379.

2736 cases now also have assertWarns and assertWarnsRegexp methods to check that a
2737 given warning type was triggered by the code under test.

Georg Brandl27a28582010-10-10 09:49:21 +00002739- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
2740 their contents without duplicating them. The view is both readable and
2741 writable.

Antoine Pitrou0d739d72010-09-05 23:01:12 +00002745- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00002746 unsupported operation is attempted (for example, writing to a file open only

Gregory P. Smith13b55292010-09-06 08:30:23 +00002749- hashlib has two new constant attributes: algorithms_guaranteed and
2750 algorithms_avaiable that respectively list the names of hash algorithms
2751 guaranteed to exist in all Python implementations and the names of hash
2752 algorithms available in the current process.
2753
Brian Quinlanaf38dc52010-09-21 12:28:43 +00002754- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00002857- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2858 now removed, since their effect was inexistent in 3.x (the default encoding is
2859 hardcoded to utf-8 and cannot be changed).

2881 return characters from the full Unicode range, even on narrow unicode builds
2882 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2883 in Python is that unicodedata.numeric() now returns the correct value for
2884 large code points, and repr() may consider more characters as printable.
2885
Victor Stinner6c00c142010-08-17 23:37:11 +00002886- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Mark Dickinson388122d2010-08-04 20:56:28 +00002920
Georg Brandl649971e2010-09-05 17:06:50 +00002921- Issue #9416: Fix some issues with complex formatting where the output with no
2922 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002923
2924 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00003264- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003265 start byte and the continuation byte(s) are now considered invalid, instead of
3266 the number of bytes specified by the start byte. E.g.:
3267 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3268 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3269 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3270 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00003284- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
3285 dealing with unary minus applied to a constant. The removed code was mutating
3286 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003287
Victor Stinner554f3f02010-06-16 23:33:54 +00003288- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003289 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003290 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003291 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003292
Victor Stinner25e8ec42010-06-25 00:02:38 +00003293- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3294 "w*" format instead. Add tests for "w*" format.
3295
Victor Stinner06e49dd2010-06-13 18:21:50 +00003296- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003297 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003298 string formats.
3299
Georg Brandl62069d32010-07-31 08:56:11 +00003300- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003301 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3302 location of the raised exception.
3303
Victor Stinner313a1202010-06-11 23:56:51 +00003304- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3305 filenames and enable os.fsencode().
3306
Benjamin Peterson285a6892010-06-22 19:21:52 +00003307- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3308
Georg Brandl62069d32010-07-31 08:56:11 +00003309- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3310 interpreter with characters outside the Basic Multilingual Plane (higher than
3311 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003312
Georg Brandl62069d32010-07-31 08:56:11 +00003313- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3314 TypeError instead of giving a DeprecationWarning when a float is parsed using
3315 the 'L' code (for long long). (All other integer codes already raise
3316 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003317
Victor Stinner600d3be2010-06-10 12:00:55 +00003318- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3319 enable shortcuts for upper case encoding name. Add also a shortcut for
3320 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3321
Georg Brandl62069d32010-07-31 08:56:11 +00003322- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3323 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003324
3325- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003326 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003327 like bytearray.
3328
Georg Brandl62069d32010-07-31 08:56:11 +00003329- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003330 used anymore and it was never documented.
3331
Georg Brandl62069d32010-07-31 08:56:11 +00003332- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003333
Georg Brandl62069d32010-07-31 08:56:11 +00003334- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3335 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003336
Georg Brandl62069d32010-07-31 08:56:11 +00003337- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3338 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3339 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3340 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003341
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003342- Issue #8748: Fix two issues with comparisons between complex and integer
3343 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003344 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3345 (2) The comparison raised an OverflowError for large integers, leading to
3346 unpredictable exceptions when combining integers and complex objects in sets
3347 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003348
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003349- Issue #8766: Initialize _warnings module before importing the first module.
3350 Fix a crash if an empty directory called "encodings" exists in sys.path.
3351
Victor Stinner9ca9c252010-05-19 16:53:30 +00003352- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003353 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003354 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003355
Georg Brandl62069d32010-07-31 08:56:11 +00003356- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3357 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003358
Victor Stinnerae6265f2010-05-15 16:27:27 +00003359- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3360 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003361 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003362 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003363
Victor Stinner59e62db2010-05-15 13:14:32 +00003364- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003365 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003366
Victor Stinnerb744ba12010-05-15 12:27:16 +00003367- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003368 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003369 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3370
Victor Stinner0964ee12010-04-30 16:48:45 +00003371- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003372 PyUnicode_FromString() to support surrogates in the filename and use the right
3373 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003374
Georg Brandl8569e582010-05-19 20:57:08 +00003375- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3376
Georg Brandl62069d32010-07-31 08:56:11 +00003377- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003378
Benjamin Petersonfb886362010-04-24 18:21:17 +00003379- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3380 arguments.
3381
Victor Stinner14284c22010-04-23 12:02:30 +00003382- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003383 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Georg Brandl62069d32010-07-31 08:56:11 +00003477 where the right hand operand is a set of constants, by turning the set into a
3478 frozenset and pre-building it as a constant. The comparison operation is made
3479 against the constant instead of building a new set each time it is executed (a
3480 similar optimization already existed which turned a list of constants into a
3481 pre-built tuple). Patch and additional tests by Dave Malcolm.

3677 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3678 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003679 to match the behaviour of the other integer format codes.

3708 gives improved memory leak detection when running under Valgrind, while taking
3709 advantage of pymalloc at other times.

3785 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003786 applications that use a lot of regular expressions and limits the impact of
3787 the performance hit anytime the cache is exceeded.

3801 defined in datetime with fast C impementation. Python implementation is based
3802 on the original python prototype for the datetime module by Tim Peters with
3803 minor modifications by the PyPy project. The test suite now tests `datetime`

Georg Brandl62069d32010-07-31 08:56:11 +00004084- Issue #8524: When creating an SSL socket, the timeout value of the original
4085 socket wasn't retained (instead, a socket with a positive timeout would be
4086 turned into a non-blocking SSL socket).

Antoine Pitroud3f8ab82010-04-24 21:26:44 +00004088- Issue #5103: SSL handshake would ignore the socket timeout and block
4089 indefinitely if the other end didn't respond.
4090
Georg Brandl62069d32010-07-31 08:56:11 +00004091- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00004159- Issue #7316: The acquire() method of lock objects in the :mod:`threading`
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00004160 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00004161 relies on the system threading library, so as to avoid a semi-busy wait loop.

Raymond Hettingerc50846a2010-04-05 18:56:31 +00004185- Add functools.total_ordering() and functools.cmp_to_key().
4186
Georg Brandl62069d32010-07-31 08:56:11 +00004187- Issue #8257: The Decimal construct now accepts a float instance directly,

4190 >>> Decimal(1.1)
4191 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00004196- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4197 InvalidOperation instead of returning False. (Comparisons involving a quiet
4198 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4199 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004200
Georg Brandl62069d32010-07-31 08:56:11 +00004201- Issue #2531: Comparison operations between floats and Decimal instances now
4202 return a result based on the numeric values of the operands; previously they
4203 returned an arbitrary result based on the relative ordering of id(float) and
4204 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4205 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004206
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004207- Added a subtract() method to collections.Counter().
4208
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004209- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004210 argument `-` which tells it to read files to compile from stdin. Each line is
4211 read on demand and the named file is compiled immediately. (Original patch by
4212 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004214- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4215 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00004216 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandl62069d32010-07-31 08:56:11 +00004218- Comparisons using one of <, <=, >, >= between a complex instance and a
4219 Fractions instance now raise TypeError instead of returning True/False. This
4220 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4221 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004264- The internals of the subprocess module on POSIX systems have been replaced by
4265 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4266 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004267
Georg Brandl62069d32010-07-31 08:56:11 +00004268- subprocess.Popen now has restore_signals and start_new_session features. The
4269 default of restore_signals=True is a new behavior compared to earlier Python
4270 versions. This means that signals such as SIGPIPE are not ignored by default
4271 in subprocesses launched by Python (Issue #1652).

Antoine Pitrou434736a2009-11-10 18:46:01 +00004547- Issue #3001: Add a C implementation of recursive locks which is used by
Georg Brandl62069d32010-07-31 08:56:11 +00004548 default when instantiating a `threading.RLock` object. This makes recursive
4549 locks as fast as regular non-recursive locks (previously, they were slower by
4550 10x to 15x).

4570 from stdin so that existing input does not confuse it and lead to incorrect
4571 entry or an IOError. It also properly flushes it afterwards to avoid the
4572 terminal echoing the input afterwards on OSes such as Solaris.

4794 Prior to this change, timezone adjustment in utctimetuple() could produce
4795 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
4796 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004798- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
4799 directive. When the ``%z`` directive is present in the format string, an
4800 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4801 ``datetime.timezone`` instance constructed from the parsed offset. If both
4802 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4803 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00004805- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00004806 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4807 ``datetime.timezone``, return fixed name and UTC offset from their
4808 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4809 returns ``None``. A class attribute, ``utc`` contains an instance
4810 representing the UTC timezone. Original patch by Rafe Kaplan.

5281Core and Builtins
5282-----------------
5283
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00005284- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
5285 of the command line.
5286
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00005287- Issue #6012: Add cleanup support to O& argument parsing.
5288
Eric Smith41669ca2009-05-23 14:23:22 +00005289- Issue #6089: Fixed str.format with certain invalid field specifiers
5290 that would raise SystemError.
5291
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005292- Issue #5982: staticmethod and classmethod now expose the wrapped
5293 function with __func__.
5294
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005295- Added support for multiple context managers in the same with-statement.
5296 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00005297
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005298- Issue #5829: complex("1e500") no longer raises OverflowError. This
5299 makes it consistent with float("1e500") and interpretation of real
5300 and imaginary literals.
5301
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005302- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
5303
R. David Murraydd226ea2009-05-13 12:27:21 +00005304- Issue #5994: the marshal module now has docstrings.
5305
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005306- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5307 (1) inf and nan strings with trailing whitespace were incorrectly
5308 rejected; (2) parsing of strings representing infinities and nans
5309 was locale aware; and (3) the interpretation of fromhex('-nan')
5310 didn't match that of float('-nan').

5313-------
5314
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00005315- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
5316
R. David Murrayfb123912009-05-28 18:19:00 +00005317- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
5318
R. David Murray1f1b9d32009-05-27 20:56:59 +00005319- Issue #6121: pydoc now ignores leading and trailing spaces in the
5320 argument to the 'help' function.
5321
Georg Brandlfaf41492009-05-26 18:31:11 +00005322- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
5323 arguments for strings with a space in them.
5324
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00005325- collections.namedtuple() was not working with the following field
5326 names: cls, self, tuple, itemgetter, and property.
5327
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005328- In unittest, using a skipping decorator on a class is now equivalent to
5329 skipping every test on the class. The ClassTestSuite class has been removed.
5330
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005331- Issue #6050: Don't fail extracting a directory from a zipfile if
5332 the directory already exists.
5333
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005334- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5335 than an int, which makes some operations possible under 64-bit Linux (e.g.
5336 DN_MULTISHOT with F_NOTIFY).
5337
Antoine Pitrou716c4442009-05-23 19:04:03 +00005338- Issue #5761: Add the name of the underlying file to the repr() of various
5339 IO objects.
5340
R. David Murraycaa27b72009-05-23 18:49:56 +00005341- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5342 by Musashi Tamura, tests by Marcin Bachry.
5343
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005344- Issue #1983: Fix functions taking or returning a process identifier to use
5345 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5346 a process identifier type wider than the standard C integer type.
5347
R. David Murray87e20742009-05-23 01:30:26 +00005348- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
5349 Patch by Farhan Ahmad, test by Marcin Bachry.
5350
Antoine Pitrou6e610062009-05-15 17:04:50 +00005351- Issue #2116: Weak references and weak dictionaries now support copy()ing and
5352 deepcopy()ing.
5353

Antoine Pitrou37d1c182009-05-14 21:54:00 +00005356- Issue #5918: Fix a crash in the parser module.
5357
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00005358- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
5359
Antoine Pitroue4501852009-05-14 18:55:55 +00005360- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5361 library. This means, for example, that opening an UTF-16 text file in
5362 append mode doesn't add a BOM at the end of the file if the file isn't
5363 empty.
5364
R. David Murray74b89242009-05-13 17:33:03 +00005365- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5366 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5367 corrects a pydoc regression.
5368
Georg Brandl5f90d792010-08-01 22:31:05 +00005369- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005370 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson932073a2009-05-23 16:14:33 +00005372Installation
5373------------
5374
5375- Issue #6047: fullinstall has been removed because Python 3's executable will
5376 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00005377
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00005378- Lib/smtpd.py is no longer installed as a script.

5401
Georg Brandl5f90d792010-08-01 22:31:05 +00005402- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
Brett Cannon1262e7c2009-05-11 01:47:11 +00005403 tests on darwin even when the OS was installed on a case-sensitive
5404 filesystem. Also fixed tests that should not be run when
5405 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005408What's New in Python 3.1 beta 1?
5409================================
5410
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005411*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005412
5413Core and Builtins
5414-----------------
5415
Mark Dickinson865e01a2009-05-07 16:37:01 +00005416- Issue #5914: Add new C API function PyOS_string_to_double, and
5417 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5418
Eric Smith741191f2009-05-06 13:08:15 +00005419- Issue #3382: float.__format__, complex.__format__, and %-formatting
5420 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5421 affects nan -> NAN and inf -> INF.
5422
Mark Hammond5a607a32009-05-06 08:04:54 +00005423- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5424 in all operations, including splitdrive, split, etc. splitunc() now issues
5425 a PendingDeprecation warning.
5426
Eric Smith63376222009-05-05 14:04:18 +00005427- Issue #5920: For float.__format__, change the behavior with the
5428 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5429 to be like 'g' but with at least one decimal point and with a
5430 default precision of 12. Previously, the behavior the same but with
5431 a default precision of 6. This more closely matches str(), and
5432 reduces surprises when adding alignment flags to the empty
5433 presentation type. This also affects the new complex.__format__ in
5434 the same way.
5435
Martin v. Löwis011e8422009-05-05 04:43:17 +00005436- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5437
R. David Murrayb18500d2009-05-04 22:59:07 +00005438- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5439 shadowed by classtype's, even if it was None. property now
5440 inserts the __doc__ into the subclass instance __dict__.
5441
Antoine Pitrou244651a2009-05-04 18:56:13 +00005442- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5443 sequences. Patch by Nick Barnes and Victor Stinner.
5444
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005445- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005446
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005447- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5448 received a new method, detach(). detach() disconnects the underlying stream
5449 from the buffer or text IO and returns it.
5450
Mark Dickinson33841c32009-05-01 15:37:04 +00005451- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5452 floats with absolute value over 1e50. Also remove length
5453 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5454 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005455
Eric Smith741191f2009-05-06 13:08:15 +00005456- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005457 format(complex(1, 2./3), '.5') now produces a sensible result.
5458
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005459- Issue #5864: Fix empty format code formatting for floats so that it
5460 never gives more than the requested number of significant digits.
5461
Eric Smith6dc46f52009-04-27 20:39:49 +00005462- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5463 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5464
Eric Smithcc32a112009-04-26 21:35:14 +00005465- Issue #5835: Deprecate PyOS_ascii_formatd.
5466
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005467- Issue #4971: Fix titlecase for characters that are their own
5468 titlecase, but not their own uppercase.
5469
Benjamin Peterson193152c2009-04-25 01:08:45 +00005470- Issue #5283: Setting __class__ in __del__ caused a segfault.
5471
Mark Dickinsonad476da2009-04-23 19:14:16 +00005472- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5473 z involves nans, infs or negative zeros.
5474
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005475- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005476
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005477- Issue #1869 (and many duplicates): make round(x, n) correctly
5478 rounded for a float x, by using the decimal <-> binary conversions
5479 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5480 consistently agrees with format(x, '.2f').
5481
Benjamin Petersonae937c02009-04-18 20:54:08 +00005482- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5483 some builtin types.
5484
Eric Smith0923d1d2009-04-16 20:16:10 +00005485- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5486
Eric Smith35e84722009-04-16 20:21:28 +00005487- Issue #5515: str.format() type 'n' combined with commas and leading
5488 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005489
5490- Implement PEP 378, Format Specifier for Thousands Separator, for
5491 floats.
5492
Mark Dickinson3370cce2009-04-17 22:40:53 +00005493- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005494 1e11, not 1e12. This avoids printing 13 significant digits in
5495 situations where only 12 of them are correct. Example problem
5496 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5497 long time.)
5498
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005499- Issue #1580: On most platforms, use a 'short' float repr: for a
5500 finite float x, repr(x) now outputs a string based on the shortest
5501 sequence of decimal digits that rounds to x. Previous behaviour was
5502 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005503 Another minor difference is that the new repr switches to
5504 exponential notation at 1e16 instead of the previous 1e17; this
5505 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005506
5507 There's a new sys attribute sys.float_repr_style, which takes
5508 the value 'short' to indicate that we're using short float repr,
5509 and 'legacy' if the short float repr isn't available for one
5510 reason or another.
5511
5512 The float repr change involves incorporating David Gay's 'perfect
5513 rounding' code into the Python core (it's in Python/dtoa.c). As a
5514 secondary consequence, all string-to-float and float-to-string
5515 conversions (including all float formatting operations) will be
5516 correctly rounded on these platforms.
5517
Georg Brandl5f90d792010-08-01 22:31:05 +00005518 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005519 this change does not apply.
5520
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005521- Issue #5759: float() didn't call __float__ on str subclasses.
5522
Georg Brandlabc38772009-04-12 15:51:51 +00005523- The string.maketrans() function is deprecated; there is a new static method
5524 maketrans() on the bytes and bytearray classes. This removes confusion about
5525 the types string.maketrans() is supposed to work with, and mirrors the
5526 methods available on the str class.
5527
R. David Murraydc6da8a2009-04-09 22:16:43 +00005528- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5529 its clarity and its speed.
5530
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005531- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005532 to avoid compiler warnings.
5533
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005534- Issue #3739: The unicode-internal encoder now reports the number of characters
5535 consumed like any other encoder (instead of the number of bytes).

5549
Raymond Hettingereb816952009-05-29 01:22:18 +00005550- Issue #5150: IDLE's format menu now has an option to strip trailing

5552
Vinay Sajipaffbd872009-06-11 10:11:47 +00005553- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005857- Issue #4935: The overflow checking code in the expandtabs() method common
5858 to str, bytes and bytearray could be optimized away by the compiler, letting
5859 the interpreter segfault instead of raising an error.
5860
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005861- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5862 __next__ method.
5863
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005864- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5865 function no longer attempt to call the __long__ slot to convert an object
5866 to an integer. Only the __int__ and __trunc__ slots are examined.

5871
Antoine Pitrouab868312009-01-10 15:40:25 +00005872- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5873 common cases are optimized thanks to a dedicated fast path and a moderate
5874 amount of loop unrolling.
5875
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005876- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5877 collecting the oldest generation) so that allocating lots of objects without
5878 destroying them does not show quadratic performance. Based on a proposal by
5879 Martin von Löwis at
5880 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5881
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005882- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005883 having been closed (for instance, a read() call could return some
5884 previously buffered data). Patch by Dmitry Vasiliev.
5885
Antoine Pitrou05608432009-01-09 18:53:14 +00005886- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5887 flag to work properly. Furthermore, when specifying -u, the text stdout
5888 and stderr streams have line-by-line buffering enabled (the default being
5889 to buffer arbitrary chunks of data).
5890
Raymond Hettinger35631532009-01-09 03:58:09 +00005891- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5892 instead of ints (reducing its size from 4 to 8 times thereby reducing
5893 Python's overall memory).
5894
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005895- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5896 an existing .py counterpart, override the co_filename attributes of all
5897 code objects if the original filename is obsolete (which can happen if the
5898 file has been renamed, moved, or if it is accessed through different paths).
5899 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5900
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005901- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5902 one byte. Also fixes the meaning of len() so that it returns the number of
5903 items, rather than the size in bytes.
5904
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005905- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005907- Issue #4747: When the terminal does not use utf-8, executing a script with

5909
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005910- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed

5914 did not get collected.
5915
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005916- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5917 where the tp_hash and tp_dict slots are both NULL.
5918
Georg Brandlccc47b62008-12-28 11:44:14 +00005919- Issue #4759: None is now allowed as the first argument of
5920 bytearray.translate(). It was always allowed for bytes.translate().
5921
Skip Montanaro80072cb2008-12-23 03:51:14 +00005922- Added test case to ensure attempts to read from a file opened for writing
5923 fail.
5924

5929
Antoine Pitrou621601a2008-12-17 23:18:19 +00005930- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

5935
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005936- Issue #2173: When getting device encoding, check that return value of
5937 nl_langinfo is not the empty string. This was causing silent build
5938 failures on OS X.
5939
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005940- Issue #4597: Fixed several opcodes that weren't always propagating
5941 exceptions.
5942
5943- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005944 context manager returns a value that cannot be converted to a bool.
5945
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005946- Issue #4445: Replace "sizeof(PyBytesObject)" with
5947 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5948 bytes instances. On a typical machine this saves 3 bytes of memory
5949 (on average) per allocation of a bytes instance.
5950
Christian Heimesa872de52008-12-05 08:26:55 +00005951- Issue #4533: File read operation was dreadfully slow due to a slowly
5952 growing read buffer. Fixed by using the same growth rate algorithm as
5953 Python 2.x.
5954
Antoine Pitrou5504e892008-12-06 21:27:53 +00005955- Issue #4509: Various issues surrounding resize of bytearray objects to
5956 which there are buffer exports (e.g. memoryview instances).
5957
Georg Brandlf9734072008-12-07 15:30:06 +00005958- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5959 method on file objects with closefd=False. The file descriptor is still
5960 kept open but the file object behaves like a closed file. The ``FileIO``
5961 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00005963- Issue #4569: Interpreter crash when mutating a memoryview with an item size

5969
Walter Dörwaldc1651a02009-05-03 22:55:55 +00005970- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5971 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5972 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5973 of using the replace error handler in PyUnicode_DecodeUTF8().
