396 Condition, etc.) used to be factory functions returning instances of hidden
397 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this
398 code pre-dates the ability to subclass extension types. It is now possible to
399 inherit from Thread and other classes, without having to import the private
400 underscored names like multiprocessing did.

499 of the script).
500

532 also opens XML files for the parser in binary mode instead of the text mode
533 to avoid encoding issues.

543
Ned Deily657b2de2011-06-28 19:51:30 -0700544- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
545 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
546 interpreter process. This could cause failures in non-Distutils subprocesses
547 and was unreliable since tests or user programs could modify the interpreter
548 environment after Distutils set it. Instead, have Distutils set the the
549 deployment target only in the environment of each build subprocess. It is
550 still possible to globally override the default by setting
551 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
552 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700553 was built. Also, implement the same handling in packaging.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00001752- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00001753 continuation line in the formatted value has no leading white space and looks
1754 like a header. Since Generator uses Header to format all headers, this check
1755 is made for all headers in any serialized message at serialization time. This
1756 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00001757
Antoine Pitrou67b212e2011-01-08 09:55:31 +00001758- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Éric Araujof0ab5d62011-05-29 03:43:59 +02001765 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00001766 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00001767
Éric Araujof0ab5d62011-05-29 03:43:59 +02001768- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00001769 rfc2047-encoding header values with embedded newlines, leaving them without
1770 folding whitespace. It now uses the continuation_ws, as it does for
1771 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00001773- Issue #1777412, #10827: Changed the rules for 2-digit years. The
1774 time.asctime(), time.ctime() and time.strftime() functions will now format
1775 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1776 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1777 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1778 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002412 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson5c4bfc42010-10-12 22:57:59 +00002757- Issue #10068: Global objects which have reference cycles with their module's
2758 dict are now cleared again. This causes issue #7140 to appear again.
2759
Victor Stinner257d38f2010-10-09 10:12:11 +00002760- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
Georg Brandl27a28582010-10-10 09:49:21 +00002761 encodings.
Victor Stinner257d38f2010-10-09 10:12:11 +00002762
Georg Brandl27a28582010-10-10 09:49:21 +00002763- ast.literal_eval() can now handle negative numbers. It is also a little more
2764 liberal in what it accepts without compromising the safety of the evaluation.
2765 For example, 3j+4 and 3+4+5 are both accepted.

Benjamin Peterson970d1882010-10-02 17:55:47 +00002767- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
2768 result metaclasses can now be ABCs (see #9533).
2769
Victor Stinneraef57e32010-10-02 11:50:49 +00002770- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
2771
Victor Stinner5593d8a2010-10-02 11:11:27 +00002772- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
Georg Brandl27a28582010-10-10 09:49:21 +00002773 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and

Brett Cannon5305a992010-09-27 21:08:38 +00002781- Issue #7397: Mention that importlib.import_module() is probably what someone

2783
Georg Brandl27a28582010-10-10 09:49:21 +00002784- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
2785 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00002787- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00002788 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Brian Curtine8e4b3b2010-09-23 20:04:14 +00002790- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
2791
Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002792- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
2793 threads are still running. Instead, reinitialize the GIL on a second call to
2794 Py_Initialize().
2795
Georg Brandl27a28582010-10-10 09:49:21 +00002796- All SyntaxErrors now have a column offset and therefore a caret when the error
2797 is printed.
Antoine Pitroub0b384b2010-09-20 20:13:48 +00002798
Brett Cannonbc2eff32010-09-19 21:39:02 +00002799- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
2800 module that was imported, but instead gets the module from sys.modules.
2801
Nick Coghlan37ee8502010-12-03 14:26:13 +00002802- Issue #9213: The range type_items now provides index() and count() methods, to
Georg Brandl27a28582010-10-10 09:49:21 +00002803 conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
Daniel Stutzbach9f0cbf12010-09-13 21:16:29 +00002804
Georg Brandl27a28582010-10-10 09:49:21 +00002805- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2806 with a non-empty format string. This is an effort to future-proof user
2807 code. If a derived class does not currently implement __format__ but later
2808 adds its own __format__, it would most likely break user code that had
2809 supplied a format string. This will be changed to a DeprecationWaring in
2810 Python 3.3 and it will be an error in Python 3.4.
Eric Smithe4d63172010-09-13 20:48:43 +00002811
Antoine Pitrou1df15362010-09-13 14:16:46 +00002812- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2813 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2814 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
2815
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002816- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2817 functions from the libc caused the methods .upper() and lower() to become
2818 locale aware and created subtly wrong results.
2819
Georg Brandl27a28582010-10-10 09:49:21 +00002820- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
2821 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00002822
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002823- Issue #4617: Previously it was illegal to delete a name from the local
2824 namespace if it occurs as a free variable in a nested block. This limitation
2825 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2826
Georg Brandl27a28582010-10-10 09:49:21 +00002827- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
2828 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
2829 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2830 single character on UCS-2 builds.
Antoine Pitroue4a18922010-09-09 20:30:23 +00002831
Antoine Pitrou6e6cc832010-09-09 12:59:39 +00002832- Issue #9757: memoryview objects get a release() method to release the
2833 underlying buffer (previously this was only done when deallocating the
2834 memoryview), and gain support for the context management protocol.
2835
Antoine Pitrou079ce542010-09-08 12:37:10 +00002836- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
2837 thread-local storage key.

R. David Murray96fd54e2010-10-08 15:55:28 +00002853- Issue #4661: email can now parse bytes input and generate either converted
2854 7bit output or bytes output. Email version bumped to 5.1.0.
2855
Antoine Pitrou59fdd672010-10-08 10:37:08 +00002856- Issue #1589: Add ssl.match_hostname(), to help implement server identity

2861
Éric Araujo6108bf52010-10-04 23:52:37 +00002862- Issue #9042: Fix interaction of custom translation classes and caching in
2863 gettext.
2864
Éric Araujoef777bd2010-10-05 00:04:20 +00002865- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002866 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002867 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002868 replacement for old handle_accept() and avoids the user to call accept()
2869 directly.

Antoine Pitrou3e1fd272010-09-28 21:23:11 +00002892- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
Georg Brandl27a28582010-10-10 09:49:21 +00002893 retry the select() loop instead of bailing out. This is because select() can
2894 incorrectly report a socket as ready for reading (for example, if it received
2895 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00002975- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00002976 it possible for the user to create self-referencing ordered dictionaries which
2977 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00002978 approach of using weakref proxies so that reference cycles never get created
2979 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00002985- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
2986 environment variable to set the filesystem encoding at Python startup.
2987 sys.setfilesystemencoding() creates inconsistencies because it is unable to
2988 reencode all filenames in all objects.
Victor Stinner5b519e02010-09-10 21:57:59 +00002989
Georg Brandl27a28582010-10-10 09:49:21 +00002990- Issue #9410: Various optimizations to the pickle module, leading to speedups

2999
Georg Brandl27a28582010-10-10 09:49:21 +00003000- Issue #9707: Rewritten reference implementation of threading.local which is
3001 friendlier towards reference cycles. This change is not normally visible
3002 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003003
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003004- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3005 still return the id of the parent process after it has exited. This process
3006 id may even have been reused by another unrelated process.
3007
Georg Brandl27a28582010-10-10 09:49:21 +00003008- Issue #9792: In case of connection failure, socket.create_connection() would
3009 swallow the exception and raise a new one, making it impossible to fetch the
3010 original errno, or to filter timeout errors. Now the original error is
3011 re-raised.

Georg Brandl27a28582010-10-10 09:49:21 +00003013- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
3014 the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
3015 back after the system call. Original patch by Brian Brazil.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003017- Updates to the random module:
3018
Georg Brandl27a28582010-10-10 09:49:21 +00003019 * Document which parts of the module are guaranteed to stay the same across
3020 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003022 * Update the seed() method to use all of the bits in a string instead of just
3023 the hash value. This makes better use of the seed value and assures the
3024 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00003026 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3027 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3028 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003029
3030 * Improved documentation of arguments to randrange(). Issue #9379.

3044
Antoine Pitrou0d739d72010-09-05 23:01:12 +00003045- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
Georg Brandl27a28582010-10-10 09:49:21 +00003046 unsupported operation is attempted (for example, writing to a file open only
3047 for reading).

Gregory P. Smith13b55292010-09-06 08:30:23 +00003049- hashlib has two new constant attributes: algorithms_guaranteed and
3050 algorithms_avaiable that respectively list the names of hash algorithms
3051 guaranteed to exist in all Python implementations and the names of hash
3052 algorithms available in the current process.
3053
Brian Quinlanaf38dc52010-09-21 12:28:43 +00003054- A new package ``concurrent.futures`` as defined by PEP 3148.

Georg Brandl649971e2010-09-05 17:06:50 +00003144- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
3145 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
3146 bytecode is a bit simplified. Patch by Demur Rumed.

Georg Brandl649971e2010-09-05 17:06:50 +00003157- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3158 now removed, since their effect was inexistent in 3.x (the default encoding is
3159 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00003160
Antoine Pitroub0fa8312010-09-01 15:10:12 +00003161- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

3163
Georg Brandl649971e2010-09-05 17:06:50 +00003164- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
3165 platforms. Previously, it inlined only when using Microsoft Visual C.

Amaury Forgeot d'Arc324ac652010-08-18 20:44:58 +00003180- Issue #5127: The C functions that access the Unicode Database now accept and
3181 return characters from the full Unicode range, even on narrow unicode builds
3182 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3183 in Python is that unicodedata.numeric() now returns the correct value for
3184 large code points, and repr() may consider more characters as printable.
3185
Victor Stinner6c00c142010-08-17 23:37:11 +00003186- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
3187 as a unicode object, instead of a byte string. Function needed to support
3188 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
3189 function.
3190

Ezio Melotti57221d02010-07-01 07:32:02 +00003564- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003565 start byte and the continuation byte(s) are now considered invalid, instead of
3566 the number of bytes specified by the start byte. E.g.:
3567 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3568 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3569 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3570 returned a single u'\ufffd'.

3599
Georg Brandl62069d32010-07-31 08:56:11 +00003600- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003601 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module

Georg Brandl62069d32010-07-31 08:56:11 +00003613- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3614 TypeError instead of giving a DeprecationWarning when a float is parsed using
3615 the 'L' code (for long long). (All other integer codes already raise
3616 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003617
Victor Stinner600d3be2010-06-10 12:00:55 +00003618- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to

3620 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3621
Georg Brandl62069d32010-07-31 08:56:11 +00003622- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3623 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003624
3625- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003626 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003627 like bytearray.
3628
Georg Brandl62069d32010-07-31 08:56:11 +00003629- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003630 used anymore and it was never documented.

Georg Brandl62069d32010-07-31 08:56:11 +00003637- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3638 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3639 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3640 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003641
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003642- Issue #8748: Fix two issues with comparisons between complex and integer
3643 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003644 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3645 (2) The comparison raised an OverflowError for large integers, leading to
3646 unpredictable exceptions when combining integers and complex objects in sets
3647 or dicts.

3951 `va_copy`, but available on all python platforms.
3952
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003953- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3954 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do

3977 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3978 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003979 to match the behaviour of the other integer format codes.

Georg Brandl62069d32010-07-31 08:56:11 +00003989- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
3990 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
3991 accessing the d_type and d_name members of structures using PyDescr_COMMON.

4008 gives improved memory leak detection when running under Valgrind, while taking
4009 advantage of pymalloc at other times.

4085 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004086 applications that use a lot of regular expressions and limits the impact of
4087 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004341- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4342 operation raises multiple signals and more than one of those signals is
4343 trapped, the specification determines the order in which the signals should be
4344 handled. In many cases this order wasn't being followed, leading to the wrong
4345 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00004501- Issue #2531: Comparison operations between floats and Decimal instances now
4502 return a result based on the numeric values of the operands; previously they

4565 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4566 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004568- subprocess.Popen now has restore_signals and start_new_session features. The
4569 default of restore_signals=True is a new behavior compared to earlier Python
4570 versions. This means that signals such as SIGPIPE are not ignored by default
4571 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004848 default when instantiating a `threading.RLock` object. This makes recursive
4849 locks as fast as regular non-recursive locks (previously, they were slower by
4850 10x to 15x).

Mark Dickinsonfa41e602010-09-28 07:22:27 +00005059- Issue #9959: Tweak formula used for computing math.log of an integer,
5060 making it marginally more accurate for exact powers of 2.

5063
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005064- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005065 compared to other unix systems. In particular, os.getgroups() does not reflect
5066 any changes made using os.setgroups() but basicly always returns the same
5067 information as the id command. os.getgroups() can now return more than 16
5068 groups on MacOSX.

5089
Benjamin Petersonf751bc92010-07-02 13:46:42 +00005090- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
5091 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00005092
Georg Brandl62069d32010-07-31 08:56:11 +00005093- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
5094 Prior to this change, timezone adjustment in utctimetuple() could produce
5095 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
5096 cases.
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00005097
Georg Brandl62069d32010-07-31 08:56:11 +00005098- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
5099 directive. When the ``%z`` directive is present in the format string, an
5100 aware ``datetime`` object is returned with ``tzinfo`` bound to a
5101 ``datetime.timezone`` instance constructed from the parsed offset. If both
5102 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
5103 name, but ``%Z`` data without ``%z`` is discarded.
Alexander Belopolskyca94f552010-06-17 18:30:34 +00005104
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00005105- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00005106 implementing ``datetime.tzinfo`` interface. Instances of the new class,
5107 ``datetime.timezone``, return fixed name and UTC offset from their
5108 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
5109 returns ``None``. A class attribute, ``utc`` contains an instance
5110 representing the UTC timezone. Original patch by Rafe Kaplan.

5120 curses module must be linked against ncurses as well. Otherwise it is not safe
5121 to load both the readline and curses modules in an application.
Stefan Kraha3ac44e2010-06-08 14:00:52 +00005122

Georg Brandl62069d32010-07-31 08:56:11 +00005126- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
5127 with an improved 'binary-split' algorithm that uses fewer multiplications and
5128 allows many of the multiplications to be performed using plain C integer
5129 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
5130 arguments.

5133 overflow checks in the audioop module.
5134
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005135- Issue #8644: The accuracy of td.total_seconds() has been improved (by
5136 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00005137 the result is now always correctly rounded, and is equivalent to ``td /
5138 timedelta(seconds=1)``.
Mark Dickinson0381e3f2010-05-08 14:35:02 +00005139
Georg Brandl62069d32010-07-31 08:56:11 +00005140- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /

5145
Mark Dickinsonc5935772010-04-03 15:54:36 +00005146- Issue #8300: When passing a non-integer argument to struct.pack with any
5147 integer format code, struct.pack first attempts to convert the non-integer
5148 using its __index__ method. If that method is non-existent or raises
5149 TypeError it goes on to try the __int__ method, as described below.
5150
Matthias Klosea8349752010-03-15 13:25:28 +00005151- Issue #8142: Update libffi to the 3.0.9 release.

5530 are always None now.
5531
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00005532- Issue #6137: The pickle module now translates module names when loading
5533 or dumping pickles with a 2.x-compatible protocol, in order to make data
5534 sharing and migration easier. This behaviour can be disabled using the
5535 new `fix_imports` optional argument.

5590 that would raise SystemError.
5591
Raymond Hettinger2bcde142009-05-29 04:52:27 +00005592- Issue #5982: staticmethod and classmethod now expose the wrapped
5593 function with __func__.
5594
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00005595- Added support for multiple context managers in the same with-statement.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00005598- Issue #5829: complex("1e500") no longer raises OverflowError. This
5599 makes it consistent with float("1e500") and interpretation of real
5600 and imaginary literals.
5601
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00005602- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00005606- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
5607 (1) inf and nan strings with trailing whitespace were incorrectly
5608 rejected; (2) parsing of strings representing infinities and nans
5609 was locale aware; and (3) the interpretation of fromhex('-nan')
5610 didn't match that of float('-nan').

5627
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005628- In unittest, using a skipping decorator on a class is now equivalent to
5629 skipping every test on the class. The ClassTestSuite class has been removed.
5630
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005631- Issue #6050: Don't fail extracting a directory from a zipfile if
5632 the directory already exists.
5633
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005634- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5635 than an int, which makes some operations possible under 64-bit Linux (e.g.
5636 DN_MULTISHOT with F_NOTIFY).
5637
Antoine Pitrou716c4442009-05-23 19:04:03 +00005638- Issue #5761: Add the name of the underlying file to the repr() of various
5639 IO objects.
5640
R. David Murraycaa27b72009-05-23 18:49:56 +00005641- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
5642 by Musashi Tamura, tests by Marcin Bachry.
5643
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005644- Issue #1983: Fix functions taking or returning a process identifier to use
5645 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5646 a process identifier type wider than the standard C integer type.
5647
R. David Murray87e20742009-05-23 01:30:26 +00005648- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5659
Antoine Pitroue4501852009-05-14 18:55:55 +00005660- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5661 library. This means, for example, that opening an UTF-16 text file in
5662 append mode doesn't add a BOM at the end of the file if the file isn't
5663 empty.
5664
R. David Murray74b89242009-05-13 17:33:03 +00005665- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5666 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5667 corrects a pydoc regression.
5668
Georg Brandl5f90d792010-08-01 22:31:05 +00005669- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005670 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00005711*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00005712
5713Core and Builtins
5714-----------------
5715
Mark Dickinson865e01a2009-05-07 16:37:01 +00005716- Issue #5914: Add new C API function PyOS_string_to_double, and
5717 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5718
Eric Smith741191f2009-05-06 13:08:15 +00005719- Issue #3382: float.__format__, complex.__format__, and %-formatting
5720 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5721 affects nan -> NAN and inf -> INF.
5722
Mark Hammond5a607a32009-05-06 08:04:54 +00005723- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5724 in all operations, including splitdrive, split, etc. splitunc() now issues
5725 a PendingDeprecation warning.
5726
Eric Smith63376222009-05-05 14:04:18 +00005727- Issue #5920: For float.__format__, change the behavior with the
5728 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5729 to be like 'g' but with at least one decimal point and with a
5730 default precision of 12. Previously, the behavior the same but with
5731 a default precision of 6. This more closely matches str(), and
5732 reduces surprises when adding alignment flags to the empty
5733 presentation type. This also affects the new complex.__format__ in
5734 the same way.
5735
Martin v. Löwis011e8422009-05-05 04:43:17 +00005736- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5737
R. David Murrayb18500d2009-05-04 22:59:07 +00005738- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5739 shadowed by classtype's, even if it was None. property now
5740 inserts the __doc__ into the subclass instance __dict__.
5741
Antoine Pitrou244651a2009-05-04 18:56:13 +00005742- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5743 sequences. Patch by Nick Barnes and Victor Stinner.
5744
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005745- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005746
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005747- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5748 received a new method, detach(). detach() disconnects the underlying stream
5749 from the buffer or text IO and returns it.
5750
Mark Dickinson33841c32009-05-01 15:37:04 +00005751- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5752 floats with absolute value over 1e50. Also remove length
5753 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5754 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005755
Eric Smith741191f2009-05-06 13:08:15 +00005756- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005757 format(complex(1, 2./3), '.5') now produces a sensible result.
5758
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005759- Issue #5864: Fix empty format code formatting for floats so that it
5760 never gives more than the requested number of significant digits.
5761
Eric Smith6dc46f52009-04-27 20:39:49 +00005762- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5763 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5764
Eric Smithcc32a112009-04-26 21:35:14 +00005765- Issue #5835: Deprecate PyOS_ascii_formatd.
5766
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005767- Issue #4971: Fix titlecase for characters that are their own
5768 titlecase, but not their own uppercase.
5769
Benjamin Peterson193152c2009-04-25 01:08:45 +00005770- Issue #5283: Setting __class__ in __del__ caused a segfault.
5771
Mark Dickinsonad476da2009-04-23 19:14:16 +00005772- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5773 z involves nans, infs or negative zeros.
5774
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005775- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005776
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005777- Issue #1869 (and many duplicates): make round(x, n) correctly
5778 rounded for a float x, by using the decimal <-> binary conversions
5779 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5780 consistently agrees with format(x, '.2f').
5781
Benjamin Petersonae937c02009-04-18 20:54:08 +00005782- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5783 some builtin types.
5784
Eric Smith0923d1d2009-04-16 20:16:10 +00005785- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5786
Eric Smith35e84722009-04-16 20:21:28 +00005787- Issue #5515: str.format() type 'n' combined with commas and leading
5788 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005789
5790- Implement PEP 378, Format Specifier for Thousands Separator, for
5791 floats.
5792
Mark Dickinson3370cce2009-04-17 22:40:53 +00005793- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005794 1e11, not 1e12. This avoids printing 13 significant digits in
5795 situations where only 12 of them are correct. Example problem
5796 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5797 long time.)
5798
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005799- Issue #1580: On most platforms, use a 'short' float repr: for a
5800 finite float x, repr(x) now outputs a string based on the shortest
5801 sequence of decimal digits that rounds to x. Previous behaviour was
5802 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005803 Another minor difference is that the new repr switches to
5804 exponential notation at 1e16 instead of the previous 1e17; this
5805 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005806
5807 There's a new sys attribute sys.float_repr_style, which takes
5808 the value 'short' to indicate that we're using short float repr,
5809 and 'legacy' if the short float repr isn't available for one
5810 reason or another.
5811
5812 The float repr change involves incorporating David Gay's 'perfect
5813 rounding' code into the Python core (it's in Python/dtoa.c). As a
5814 secondary consequence, all string-to-float and float-to-string
5815 conversions (including all float formatting operations) will be
5816 correctly rounded on these platforms.

Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005819 this change does not apply.

5822
Georg Brandlabc38772009-04-12 15:51:51 +00005823- The string.maketrans() function is deprecated; there is a new static method
5824 maketrans() on the bytes and bytearray classes. This removes confusion about
5825 the types string.maketrans() is supposed to work with, and mirrors the
5826 methods available on the str class.

6107
Eric Smith5e5c0db2009-02-20 14:25:03 +00006108- Issue #5247: Improve error message when unknown format codes are
6109 used when using str.format() with str, int, and float arguments.
6110
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006111- Issue #5249: time.strftime returned malformed string when format string
6112 contained non ascii character on windows.
6113
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006114- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6115 source has already been decoded into str.
6116
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006117- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6118 rotating the object pointer by 4 bits to the right.
6119
Mark Dickinson87ec0852009-02-09 17:15:59 +00006120- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6121 it now forces its argument to double before testing for infinity.
6122
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006123- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6124 returns a non-number type.
6125
Benjamin Peterson87618552009-02-08 15:00:52 +00006126- Issue #5182: Removed memoryview.__str__.
6127
Mark Dickinsonc008a172009-02-01 13:59:22 +00006128- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6129 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006130 the type definition cmpfunc. The tp_compare slot has been renamed
6131 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006132
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006133- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006134 were suppressing all exceptions. These include list() and bytearray().
6135
Mark Dickinson1124e712009-01-28 21:25:58 +00006136- Issue #4707: round(x, n) now returns an integer if x is an integer.
6137 Previously it returned a float.
6138
Antoine Pitroub52ec782009-01-25 16:34:23 +00006139- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6140 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6141 evaluation loop is compiled with a new dispatch mechanism which gives
6142 speedups of up to 20%, depending on the system, on various benchmarks.
6143
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006144- Issue #4874: Most builtin decoders now reject unicode input.

6152 optional module state data.
6153
Mark Dickinson8055afd2009-01-17 10:04:45 +00006154- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006155 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006156
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006157- Issue #4935: The overflow checking code in the expandtabs() method common
6158 to str, bytes and bytearray could be optimized away by the compiler, letting
6159 the interpreter segfault instead of raising an error.
6160
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006161- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6162 __next__ method.
6163
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006164- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6165 function no longer attempt to call the __long__ slot to convert an object
6166 to an integer. Only the __int__ and __trunc__ slots are examined.
6167
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00006168- Issue #4893: Use NT threading on CE.
6169

6171
Antoine Pitrouab868312009-01-10 15:40:25 +00006172- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6173 common cases are optimized thanks to a dedicated fast path and a moderate
6174 amount of loop unrolling.
6175
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006176- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6177 collecting the oldest generation) so that allocating lots of objects without
6178 destroying them does not show quadratic performance. Based on a proposal by
6179 Martin von Löwis at
6180 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6181
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006182- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006183 having been closed (for instance, a read() call could return some
6184 previously buffered data). Patch by Dmitry Vasiliev.
6185
Antoine Pitrou05608432009-01-09 18:53:14 +00006186- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6187 flag to work properly. Furthermore, when specifying -u, the text stdout
6188 and stderr streams have line-by-line buffering enabled (the default being
6189 to buffer arbitrary chunks of data).
6190
Raymond Hettinger35631532009-01-09 03:58:09 +00006191- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6192 instead of ints (reducing its size from 4 to 8 times thereby reducing
6193 Python's overall memory).
6194
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006195- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6196 an existing .py counterpart, override the co_filename attributes of all
6197 code objects if the original filename is obsolete (which can happen if the
6198 file has been renamed, moved, or if it is accessed through different paths).
6199 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6200
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006201- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6202 one byte. Also fixes the meaning of len() so that it returns the number of
6203 items, rather than the size in bytes.
6204
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006205- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6206
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006207- Issue #4747: When the terminal does not use utf-8, executing a script with
6208 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6209
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006210- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6211 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006212
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006213- Issue #3680: Reference cycles created through a dict, set or deque iterator
6214 did not get collected.
6215
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006216- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6217 where the tp_hash and tp_dict slots are both NULL.
6218
Georg Brandlccc47b62008-12-28 11:44:14 +00006219- Issue #4759: None is now allowed as the first argument of
6220 bytearray.translate(). It was always allowed for bytes.translate().
6221
Skip Montanaro80072cb2008-12-23 03:51:14 +00006222- Added test case to ensure attempts to read from a file opened for writing
6223 fail.
6224
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006225- Issue #3106: Speedup some comparisons (str/str and int/int).

6228 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6229
Antoine Pitrou621601a2008-12-17 23:18:19 +00006230- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6231 print elapsed times, not only when some objects are uncollectable /
6232 unreachable. Original patch by Neil Schemenauer.
6233
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006234- Issue #3439: Add a bit_length method to int.
6235
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006236- Issue #2173: When getting device encoding, check that return value of
6237 nl_langinfo is not the empty string. This was causing silent build
6238 failures on OS X.
6239
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006240- Issue #4597: Fixed several opcodes that weren't always propagating
6241 exceptions.
6242
6243- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006244 context manager returns a value that cannot be converted to a bool.
6245
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006246- Issue #4445: Replace "sizeof(PyBytesObject)" with
6247 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6248 bytes instances. On a typical machine this saves 3 bytes of memory
6249 (on average) per allocation of a bytes instance.
6250
Christian Heimesa872de52008-12-05 08:26:55 +00006251- Issue #4533: File read operation was dreadfully slow due to a slowly
6252 growing read buffer. Fixed by using the same growth rate algorithm as
6253 Python 2.x.
6254
Antoine Pitrou5504e892008-12-06 21:27:53 +00006255- Issue #4509: Various issues surrounding resize of bytearray objects to
6256 which there are buffer exports (e.g. memoryview instances).
6257
Georg Brandlf9734072008-12-07 15:30:06 +00006258- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6259 method on file objects with closefd=False. The file descriptor is still
6260 kept open but the file object behaves like a closed file. The ``FileIO``
6261 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00006262
Antoine Pitroubc420402008-12-07 20:14:49 +00006263- Issue #4569: Interpreter crash when mutating a memoryview with an item size
6264 larger than 1.

6269
Walter Dörwaldc1651a02009-05-03 22:55:55 +00006270- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
6271 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6272 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6273 of using the replace error handler in PyUnicode_DecodeUTF8().
