Antoine Pitrou11942a52011-11-28 19:08:36 +010023- Issue #7111: Python can now be run without a stdin, stdout or stderr
24 stream. It was already the case with Python 2. However, the corresponding
25 sys module entries are now set to None (instead of an unusable file object).
26
Antoine Pitrouf0effe62011-11-26 01:11:02 +010027- Issue #11849: Ensure that free()d memory arenas are really released

Victor Stinner6345be92011-11-25 20:09:01 +010032 different than "strict" anymore. The caller was unable to compute the
33 size of the output buffer: it depends on the error handler.
34

48 Stefan Behnel.
49
Antoine Pitrou56a220a2011-11-16 00:56:10 +010050- Issue #13393: BufferedReader.read1() now asks the full requested size to
51 the raw stream instead of limiting itself to the buffer size.
52
Antoine Pitrou28e401e2011-11-15 19:15:19 +010053- Issue #13392: Writing a pyc file should now be atomic under Windows as well.
54
Antoine Pitrou5418ee02011-11-15 01:42:21 +010055- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
56 already accepts them).
57
Antoine Pitrou9a812cb2011-11-15 00:00:12 +010058- Issue #13389: Full garbage collection passes now clear the freelists for
59 list and dict objects. They already cleared other freelists in the
60 interpreter.
61
Brian Curtin52fbea12011-11-06 13:41:17 -060062- Issue #13327: Remove the need for an explicit None as the second argument

64 order to update to the current time. Also added keyword argument
65 handling to os.utimensat in order to remove the need for explicit None.

92 object identity).
93
Nick Coghlande31b192011-10-23 22:04:16 +100094- Issue #1294232: In a few cases involving metaclass inheritance, the

Ned Deily657b2de2011-06-28 19:51:30 -0700938- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
939 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
940 interpreter process. This could cause failures in non-Distutils subprocesses
941 and was unreliable since tests or user programs could modify the interpreter
942 environment after Distutils set it. Instead, have Distutils set the the
943 deployment target only in the environment of each build subprocess. It is
944 still possible to globally override the default by setting
945 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
946 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -0700947 was built. Also, implement the same handling in packaging.

2838
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002839- Issue #5437: A preallocated MemoryError instance should not keep traceback

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002848- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2849 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002850 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002851 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002852 encoding and to encode command line arguments on this OS.
2853

2855 filenames encoded to the filesystem encoding with the surrogateescape error
Victor Stinner4c7c8c32010-10-16 13:14:10 +00002856 handler (to support undecodable bytes), instead of UTF-8 in strict mode.
2857
Benjamin Peterson230b2062010-10-16 03:45:45 +00002858- Issue #9997: Don't let the name "top" have special significance in scope
2859 resolution.
2860
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002861- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002967 incorrectly validated some non-compliant applications as WSGI compliant; if
2968 your app validates with Python <3.2b1+, but not on this version, it is likely
2969 the case that your app was not compliant.)

Georg Brandl27a28582010-10-10 09:49:21 +00003214 UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
3215 32 bits wchar_t (eg. Linux in narrow build).

Brett Cannon5305a992010-09-27 21:08:38 +00003222- Issue #7397: Mention that importlib.import_module() is probably what someone

3224
Georg Brandl27a28582010-10-10 09:49:21 +00003225- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
3226 to use named arguments.

Mark Dickinsonb09a3d62010-09-23 20:11:19 +00003228- Issue #9930: Remove bogus subtype check that was causing (e.g.)
Georg Brandl27a28582010-10-10 09:49:21 +00003229 float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00003233- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
3234 threads are still running. Instead, reinitialize the GIL on a second call to
3235 Py_Initialize().
3236
Georg Brandl27a28582010-10-10 09:49:21 +00003237- All SyntaxErrors now have a column offset and therefore a caret when the error
3238 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00003240- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
3241 module that was imported, but instead gets the module from sys.modules.
3242
Nick Coghlan37ee8502010-12-03 14:26:13 +00003243- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00003246- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3247 with a non-empty format string. This is an effort to future-proof user
3248 code. If a derived class does not currently implement __format__ but later
3249 adds its own __format__, it would most likely break user code that had
3250 supplied a format string. This will be changed to a DeprecationWaring in
3251 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00003253- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
3254 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
3255 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
3256
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00003257- Issue #9210: Configure option --with-wctype-functions was removed. Using the
3258 functions from the libc caused the methods .upper() and lower() to become
3259 locale aware and created subtly wrong results.
3260
Georg Brandl27a28582010-10-10 09:49:21 +00003261- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
3262 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00003263
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00003264- Issue #4617: Previously it was illegal to delete a name from the local
3265 namespace if it occurs as a free variable in a nested block. This limitation
3266 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
3267
Georg Brandl27a28582010-10-10 09:49:21 +00003268- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3269 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3270 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3271 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00003273- Issue #9757: memoryview objects get a release() method to release the
3274 underlying buffer (previously this was only done when deallocating the
3275 memoryview), and gain support for the context management protocol.
3276
Antoine Pitrou079ce542010-09-08 12:37:10 +00003277- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00003306- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003307 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003308 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003309 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003334 retry the select() loop instead of bailing out. This is because select() can
3335 incorrectly report a socket as ready for reading (for example, if it received
3336 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003416- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003417 it possible for the user to create self-referencing ordered dictionaries which
3418 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003419 approach of using weakref proxies so that reference cycles never get created

3428 sys.setfilesystemencoding() creates inconsistencies because it is unable to

3447 id may even have been reused by another unrelated process.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003458- Updates to the random module:
3459
Georg Brandl27a28582010-10-10 09:49:21 +00003460 * Document which parts of the module are guaranteed to stay the same across
3461 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003462
Georg Brandl27a28582010-10-10 09:49:21 +00003463 * Update the seed() method to use all of the bits in a string instead of just
3464 the hash value. This makes better use of the seed value and assures the
3465 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003466
Georg Brandl27a28582010-10-10 09:49:21 +00003467 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3468 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3469 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003470
3471 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003490- hashlib has two new constant attributes: algorithms_guaranteed and
3491 algorithms_avaiable that respectively list the names of hash algorithms
3492 guaranteed to exist in all Python implementations and the names of hash
3493 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00003598- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
3599 now removed, since their effect was inexistent in 3.x (the default encoding is

3622 return characters from the full Unicode range, even on narrow unicode builds
3623 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3624 in Python is that unicodedata.numeric() now returns the correct value for
3625 large code points, and repr() may consider more characters as printable.
3626
Victor Stinner6c00c142010-08-17 23:37:11 +00003627- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00003651- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3652 use PyUnicode_FromFormatV() to format the warning message.

3660 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003661
Georg Brandl649971e2010-09-05 17:06:50 +00003662- Issue #9416: Fix some issues with complex formatting where the output with no
3663 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003664
3665 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00004005- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00004006 start byte and the continuation byte(s) are now considered invalid, instead of
4007 the number of bytes specified by the start byte. E.g.:
4008 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4009 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4010 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4011 returned a single u'\ufffd'.

4026 dealing with unary minus applied to a constant. The removed code was mutating
4027 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00004031 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00004032 handlers. Patch written by Mark Hammond.

4040
Georg Brandl62069d32010-07-31 08:56:11 +00004041- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00004042 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
4043 location of the raised exception.
4044
Victor Stinner313a1202010-06-11 23:56:51 +00004045- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
4046 filenames and enable os.fsencode().
4047
Benjamin Peterson285a6892010-06-22 19:21:52 +00004048- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.

Georg Brandl62069d32010-07-31 08:56:11 +00004054- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
4055 TypeError instead of giving a DeprecationWarning when a float is parsed using
4056 the 'L' code (for long long). (All other integer codes already raise
4057 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00004058
Victor Stinner600d3be2010-06-10 12:00:55 +00004059- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
4060 enable shortcuts for upper case encoding name. Add also a shortcut for
4061 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4062
Georg Brandl62069d32010-07-31 08:56:11 +00004063- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
4064 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004065
4066- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00004067 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004068 like bytearray.
4069
Georg Brandl62069d32010-07-31 08:56:11 +00004070- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00004071 used anymore and it was never documented.
4072
Georg Brandl62069d32010-07-31 08:56:11 +00004073- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00004075- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
4076 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00004077
Georg Brandl62069d32010-07-31 08:56:11 +00004078- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
4079 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4080 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4081 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00004082
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004083- Issue #8748: Fix two issues with comparisons between complex and integer
4084 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004085 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4086 (2) The comparison raised an OverflowError for large integers, leading to
4087 unpredictable exceptions when combining integers and complex objects in sets
4088 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004089
Victor Stinner7d79b8b2010-05-19 20:40:50 +00004090- Issue #8766: Initialize _warnings module before importing the first module.

4092
Victor Stinner9ca9c252010-05-19 16:53:30 +00004093- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00004094 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00004095 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00004096
Georg Brandl62069d32010-07-31 08:56:11 +00004097- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
4098 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00004099
Victor Stinnerae6265f2010-05-15 16:27:27 +00004100- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
4101 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00004102 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00004103 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00004104
Victor Stinner59e62db2010-05-15 13:14:32 +00004105- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00004106 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00004107
Victor Stinnerb744ba12010-05-15 12:27:16 +00004108- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00004109 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00004110 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
4111
Victor Stinner0964ee12010-04-30 16:48:45 +00004112- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00004113 PyUnicode_FromString() to support surrogates in the filename and use the right
4114 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00004116- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
4117
Georg Brandl62069d32010-07-31 08:56:11 +00004118- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00004119
Benjamin Petersonfb886362010-04-24 18:21:17 +00004120- Issue #8419: Prevent the dict constructor from accepting non-string keyword
4121 arguments.
4122
Victor Stinner14284c22010-04-23 12:02:30 +00004123- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00004124 indirectly Python signal handlers anymore because mywrite() ignores exceptions

4392 `va_copy`, but available on all python platforms.
4393
Mark Dickinsone6fc7402010-08-06 18:55:26 +00004394- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
4395 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
4396 "step = -step" when reversing a slice.

4418 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
4419 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00004420 to match the behaviour of the other integer format codes.

Antoine Pitrou3060c452010-08-13 16:27:38 +00004525 simply clearing the entire cache on overflow to forgetting the least recently
4526 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004527 applications that use a lot of regular expressions and limits the impact of
4528 the performance hit anytime the cache is exceeded.

4541 module is renamed to `_datetime` and if available, overrides all classes
4542 defined in datetime with fast C impementation. Python implementation is based
4543 on the original python prototype for the datetime module by Tim Peters with
4544 minor modifications by the PyPy project. The test suite now tests `datetime`

4943 return a result based on the numeric values of the operands; previously they
4944 returned an arbitrary result based on the relative ordering of id(float) and
4945 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004950- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004951 argument `-` which tells it to read files to compile from stdin. Each line is

4961 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4962 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005009- subprocess.Popen now has restore_signals and start_new_session features. The
5010 default of restore_signals=True is a new behavior compared to earlier Python
5011 versions. This means that signals such as SIGPIPE are not ignored by default
5012 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00005098- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
5099 position when calling `truncate()`. It would previously change the file
5100 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00005101 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00005103- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00005104 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
5105 archive. The new implementation is significantly faster and can be wrapped in
5106 a :class:`io.BufferedReader` object for more speedups. It also solves an
5107 issue where interleaved calls to `read()` and `readline()` give wrong results.
5108 Patch by Nir Aides.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005505- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005506 compared to other unix systems. In particular, os.getgroups() does not reflect

6074
Antoine Pitrou61f77b52009-05-24 15:46:13 +00006075- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
6076 than an int, which makes some operations possible under 64-bit Linux (e.g.
6077 DN_MULTISHOT with F_NOTIFY).
6078
Antoine Pitrou716c4442009-05-23 19:04:03 +00006079- Issue #5761: Add the name of the underlying file to the repr() of various

6100
Antoine Pitroue4501852009-05-14 18:55:55 +00006101- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
6102 library. This means, for example, that opening an UTF-16 text file in
6103 append mode doesn't add a BOM at the end of the file if the file isn't
6104 empty.
6105
R. David Murray74b89242009-05-13 17:33:03 +00006106- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

6108 corrects a pydoc regression.
6109
Georg Brandl5f90d792010-08-01 22:31:05 +00006110- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00006111 now it does. This also means getfp method now returns the real fp.

6154Core and Builtins
6155-----------------
6156
Mark Dickinson865e01a2009-05-07 16:37:01 +00006157- Issue #5914: Add new C API function PyOS_string_to_double, and
6158 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6159
Eric Smith741191f2009-05-06 13:08:15 +00006160- Issue #3382: float.__format__, complex.__format__, and %-formatting
6161 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6162 affects nan -> NAN and inf -> INF.
6163
Mark Hammond5a607a32009-05-06 08:04:54 +00006164- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6165 in all operations, including splitdrive, split, etc. splitunc() now issues
6166 a PendingDeprecation warning.
6167
Eric Smith63376222009-05-05 14:04:18 +00006168- Issue #5920: For float.__format__, change the behavior with the
6169 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6170 to be like 'g' but with at least one decimal point and with a
6171 default precision of 12. Previously, the behavior the same but with
6172 a default precision of 6. This more closely matches str(), and
6173 reduces surprises when adding alignment flags to the empty
6174 presentation type. This also affects the new complex.__format__ in
6175 the same way.
6176
Martin v. Löwis011e8422009-05-05 04:43:17 +00006177- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6178
R. David Murrayb18500d2009-05-04 22:59:07 +00006179- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6180 shadowed by classtype's, even if it was None. property now
6181 inserts the __doc__ into the subclass instance __dict__.
6182
Antoine Pitrou244651a2009-05-04 18:56:13 +00006183- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6184 sequences. Patch by Nick Barnes and Victor Stinner.
6185
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006186- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006187
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006188- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6189 received a new method, detach(). detach() disconnects the underlying stream
6190 from the buffer or text IO and returns it.
6191
Mark Dickinson33841c32009-05-01 15:37:04 +00006192- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6193 floats with absolute value over 1e50. Also remove length
6194 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6195 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006196
Eric Smith741191f2009-05-06 13:08:15 +00006197- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006198 format(complex(1, 2./3), '.5') now produces a sensible result.
6199
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006200- Issue #5864: Fix empty format code formatting for floats so that it
6201 never gives more than the requested number of significant digits.
6202
Eric Smith6dc46f52009-04-27 20:39:49 +00006203- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6204 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6205
Eric Smithcc32a112009-04-26 21:35:14 +00006206- Issue #5835: Deprecate PyOS_ascii_formatd.
6207
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006208- Issue #4971: Fix titlecase for characters that are their own
6209 titlecase, but not their own uppercase.
6210
Benjamin Peterson193152c2009-04-25 01:08:45 +00006211- Issue #5283: Setting __class__ in __del__ caused a segfault.
6212
Mark Dickinsonad476da2009-04-23 19:14:16 +00006213- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6214 z involves nans, infs or negative zeros.
6215
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006216- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006217
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006218- Issue #1869 (and many duplicates): make round(x, n) correctly
6219 rounded for a float x, by using the decimal <-> binary conversions
6220 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6221 consistently agrees with format(x, '.2f').
6222
Benjamin Petersonae937c02009-04-18 20:54:08 +00006223- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6224 some builtin types.
6225
Eric Smith0923d1d2009-04-16 20:16:10 +00006226- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6227
Eric Smith35e84722009-04-16 20:21:28 +00006228- Issue #5515: str.format() type 'n' combined with commas and leading
6229 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006230
6231- Implement PEP 378, Format Specifier for Thousands Separator, for
6232 floats.
6233
Mark Dickinson3370cce2009-04-17 22:40:53 +00006234- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006235 1e11, not 1e12. This avoids printing 13 significant digits in
6236 situations where only 12 of them are correct. Example problem
6237 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6238 long time.)
6239
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006240- Issue #1580: On most platforms, use a 'short' float repr: for a
6241 finite float x, repr(x) now outputs a string based on the shortest
6242 sequence of decimal digits that rounds to x. Previous behaviour was
6243 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006244 Another minor difference is that the new repr switches to
6245 exponential notation at 1e16 instead of the previous 1e17; this
6246 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006247
6248 There's a new sys attribute sys.float_repr_style, which takes
6249 the value 'short' to indicate that we're using short float repr,
6250 and 'legacy' if the short float repr isn't available for one
6251 reason or another.
6252
6253 The float repr change involves incorporating David Gay's 'perfect
6254 rounding' code into the Python core (it's in Python/dtoa.c). As a
6255 secondary consequence, all string-to-float and float-to-string
6256 conversions (including all float formatting operations) will be
6257 correctly rounded on these platforms.
6258
Georg Brandl5f90d792010-08-01 22:31:05 +00006259 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006260 this change does not apply.
6261
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006262- Issue #5759: float() didn't call __float__ on str subclasses.
6263
Georg Brandlabc38772009-04-12 15:51:51 +00006264- The string.maketrans() function is deprecated; there is a new static method
6265 maketrans() on the bytes and bytearray classes. This removes confusion about
6266 the types string.maketrans() is supposed to work with, and mirrors the
6267 methods available on the str class.
6268
R. David Murraydc6da8a2009-04-09 22:16:43 +00006269- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6270 its clarity and its speed.
6271
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006272- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006273 to avoid compiler warnings.
6274
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006275- Issue #3739: The unicode-internal encoder now reports the number of characters
6276 consumed like any other encoder (instead of the number of bytes).

6357 results in a handle_expt_event call, not handle_read_event, and POLLERR
6358 and POLLNVAL now call handle_close, not handle_expt_event. Also,
6359 dispatcher now has an 'ignore_log_types' attribute for suppressing
6360 log messages, which is set to 'warning' by default.

6436 untrackable objects are not tracked by the garbage collector. This can
6437 reduce the size of collections and therefore the garbage collection overhead
6438 on long-running programs, depending on their particular use of datatypes.

6509 forever on incomplete input. That caused tarfile.open() to hang when used
6510 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6511 partial bzip2 compressed data.

Raymond Hettinger35631532009-01-09 03:58:09 +00006632- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6633 instead of ints (reducing its size from 4 to 8 times thereby reducing
6634 Python's overall memory).
6635
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006636- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6637 an existing .py counterpart, override the co_filename attributes of all
6638 code objects if the original filename is obsolete (which can happen if the
6639 file has been renamed, moved, or if it is accessed through different paths).

Mark Dickinsonfd24b322008-12-06 15:33:31 +00006687- Issue #4445: Replace "sizeof(PyBytesObject)" with
6688 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6689 bytes instances. On a typical machine this saves 3 bytes of memory
6690 (on average) per allocation of a bytes instance.
6691
Christian Heimesa872de52008-12-05 08:26:55 +00006692- Issue #4533: File read operation was dreadfully slow due to a slowly

6694 Python 2.x.
6695
Antoine Pitrou5504e892008-12-06 21:27:53 +00006696- Issue #4509: Various issues surrounding resize of bytearray objects to

6698
Georg Brandlf9734072008-12-07 15:30:06 +00006699- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
6700 method on file objects with closefd=False. The file descriptor is still
6701 kept open but the file object behaves like a closed file. The ``FileIO``
6702 object also got a new readonly attribute ``closefd``.

6712 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6713 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6714 of using the replace error handler in PyUnicode_DecodeUTF8().

7033
Antoine Pitrou08838b62009-01-21 00:55:13 +00007034- Issue #5008: When a file is opened in append mode with the new IO library,
7035 do an explicit seek to the end of file (so that e.g. tell() returns the
7036 file size rather than 0). This is consistent with the behaviour of the

7067 appropriately when it is being used via socket.makefile() objects
7068 rather than delaying the close by waiting for garbage collection to do it.
7069
Raymond Hettingerb8baf632009-01-14 02:20:07 +00007070- Issue #1696199: Add collections.Counter() for rapid and convenient
