Antoine Pitrou84f1b172011-07-12 21:57:15 +0200311 cleared by the garbage collector. This fixes a segfault when an instance
312 and its type get caught in a reference cycle, and the instance's
313 deallocator calls one of the methods on the type (e.g. when subclassing
314 IOBase). Diagnosis and patch by Davide Rizzo.

560 environment after Distutils set it. Instead, have Distutils set the the

562 still possible to globally override the default by setting

565 was built.

1300 of HTTP 1.1.
1301
Armin Ronacher59531282011-01-22 13:44:22 +00001302- To match the behaviour of HTTP server, the HTTP client library now also
1303 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
1304 that for incoming headers which makes this behaviour now consistent in
1305 both incoming and outgoing direction.

1427 time.asctime(), time.ctime() and time.strftime() functions will now format
1428 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1429 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
1430 supported by the OS. With Visual Studio or on Solaris, the year is limited to
1431 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002060- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2061 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002062 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002063 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002443- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other

2445 Py_Initialize().
2446
Georg Brandl27a28582010-10-10 09:49:21 +00002447- All SyntaxErrors now have a column offset and therefore a caret when the error

Nick Coghlan37ee8502010-12-03 14:26:13 +00002453- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002456- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2457 with a non-empty format string. This is an effort to future-proof user
2458 code. If a derived class does not currently implement __format__ but later
2459 adds its own __format__, it would most likely break user code that had
2460 supplied a format string. This will be changed to a DeprecationWaring in
2461 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002463- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2464 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2465 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002467- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2468 functions from the libc caused the methods .upper() and lower() to become

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002474- Issue #4617: Previously it was illegal to delete a name from the local
2475 namespace if it occurs as a free variable in a nested block. This limitation
2476 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2477
Georg Brandl27a28582010-10-10 09:49:21 +00002478- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2480 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2481 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002516- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002517 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002518 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002519 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002544 retry the select() loop instead of bailing out. This is because select() can

Georg Brandl27a28582010-10-10 09:49:21 +00002627 it possible for the user to create self-referencing ordered dictionaries which
2628 become permanently uncollectable GC garbage. Reinstated the Python 3.1

Georg Brandl27a28582010-10-10 09:49:21 +00002673 * Update the seed() method to use all of the bits in a string instead of just
2674 the hash value. This makes better use of the seed value and assures the
2675 seeding is platform independent. Issue #7889.

2832 return characters from the full Unicode range, even on narrow unicode builds
2833 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2834 in Python is that unicodedata.numeric() now returns the correct value for
2835 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002872- Issue #9416: Fix some issues with complex formatting where the output with no
2873 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002874
2875 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

3214
Ezio Melotti57221d02010-07-01 07:32:02 +00003215- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003216 start byte and the continuation byte(s) are now considered invalid, instead of
3217 the number of bytes specified by the start byte. E.g.:
3218 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3219 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3220 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3221 returned a single u'\ufffd'.

3236 dealing with unary minus applied to a constant. The removed code was mutating
3237 the ST, causing a second compilation to fail.

Georg Brandl62069d32010-07-31 08:56:11 +00003240 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003241 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003242 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003243
Victor Stinner25e8ec42010-06-25 00:02:38 +00003244- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3245 "w*" format instead. Add tests for "w*" format.
3246
Victor Stinner06e49dd2010-06-13 18:21:50 +00003247- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003248 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003249 string formats.
3250
Georg Brandl62069d32010-07-31 08:56:11 +00003251- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003252 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3253 location of the raised exception.
3254
Victor Stinner313a1202010-06-11 23:56:51 +00003255- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3256 filenames and enable os.fsencode().
3257
Benjamin Peterson285a6892010-06-22 19:21:52 +00003258- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3259
Georg Brandl62069d32010-07-31 08:56:11 +00003260- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3261 interpreter with characters outside the Basic Multilingual Plane (higher than
3262 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003263
Georg Brandl62069d32010-07-31 08:56:11 +00003264- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3265 TypeError instead of giving a DeprecationWarning when a float is parsed using
3266 the 'L' code (for long long). (All other integer codes already raise
3267 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003268
Victor Stinner600d3be2010-06-10 12:00:55 +00003269- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3270 enable shortcuts for upper case encoding name. Add also a shortcut for
3271 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3272
Georg Brandl62069d32010-07-31 08:56:11 +00003273- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3274 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003275
3276- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003277 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003278 like bytearray.
3279
Georg Brandl62069d32010-07-31 08:56:11 +00003280- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003281 used anymore and it was never documented.
3282
Georg Brandl62069d32010-07-31 08:56:11 +00003283- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003284
Georg Brandl62069d32010-07-31 08:56:11 +00003285- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3286 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003287
Georg Brandl62069d32010-07-31 08:56:11 +00003288- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3289 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3290 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3291 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003292
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003293- Issue #8748: Fix two issues with comparisons between complex and integer
3294 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003295 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3296 (2) The comparison raised an OverflowError for large integers, leading to
3297 unpredictable exceptions when combining integers and complex objects in sets
3298 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003299
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003300- Issue #8766: Initialize _warnings module before importing the first module.
3301 Fix a crash if an empty directory called "encodings" exists in sys.path.
3302
Victor Stinner9ca9c252010-05-19 16:53:30 +00003303- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003304 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003305 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003306
Georg Brandl62069d32010-07-31 08:56:11 +00003307- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3308 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003309
Victor Stinnerae6265f2010-05-15 16:27:27 +00003310- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3311 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003312 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003313 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003314
Victor Stinner59e62db2010-05-15 13:14:32 +00003315- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003316 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003317
Victor Stinnerb744ba12010-05-15 12:27:16 +00003318- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003319 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003320 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3321
Victor Stinner0964ee12010-04-30 16:48:45 +00003322- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003323 PyUnicode_FromString() to support surrogates in the filename and use the right
3324 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003325
Georg Brandl8569e582010-05-19 20:57:08 +00003326- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3327
Georg Brandl62069d32010-07-31 08:56:11 +00003328- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003329
Benjamin Petersonfb886362010-04-24 18:21:17 +00003330- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3331 arguments.
3332
Victor Stinner14284c22010-04-23 12:02:30 +00003333- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003334 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00003427- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00003428 where the right hand operand is a set of constants, by turning the set into a
3429 frozenset and pre-building it as a constant. The comparison operation is made
3430 against the constant instead of building a new set each time it is executed (a
3431 similar optimization already existed which turned a list of constants into a
3432 pre-built tuple). Patch and additional tests by Dave Malcolm.

Antoine Pitrou8689a102010-04-01 16:53:15 +00003616- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00003617 function declaration, which was kept for backwards compatibility reasons, is
3618 now removed (the macro was introduced in 1997!).

3628 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3629 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003630 to match the behaviour of the other integer format codes.
3631

Georg Brandl62069d32010-07-31 08:56:11 +00003657- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3658 allocator will be automatically disabled when running under Valgrind. This
3659 gives improved memory leak detection when running under Valgrind, while taking
3660 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00003733- The default size of the re module's compiled regular expression cache has been
3734 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00003735 simply clearing the entire cache on overflow to forgetting the least recently
3736 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003737 applications that use a lot of regular expressions and limits the impact of
3738 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00003750- Issue #7989: Added pure python implementation of the `datetime` module. The C
3751 module is renamed to `_datetime` and if available, overrides all classes
3752 defined in datetime with fast C impementation. Python implementation is based
3753 on the original python prototype for the datetime module by Tim Peters with
3754 minor modifications by the PyPy project. The test suite now tests `datetime`
3755 module with and without `_datetime` acceleration using the same test cases.

Georg Brandl62069d32010-07-31 08:56:11 +00004147- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4148 InvalidOperation instead of returning False. (Comparisons involving a quiet
4149 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4150 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004152- Issue #2531: Comparison operations between floats and Decimal instances now
4153 return a result based on the numeric values of the operands; previously they
4154 returned an arbitrary result based on the relative ordering of id(float) and
4155 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4156 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004157
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004158- Added a subtract() method to collections.Counter().
4159
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004160- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004161 argument `-` which tells it to read files to compile from stdin. Each line is
4162 read on demand and the named file is compiled immediately. (Original patch by
4163 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004165- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

4170 Fractions instance now raise TypeError instead of returning True/False. This
4171 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4172 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004215- The internals of the subprocess module on POSIX systems have been replaced by
4216 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4217 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00004219- subprocess.Popen now has restore_signals and start_new_session features. The
4220 default of restore_signals=True is a new behavior compared to earlier Python
4221 versions. This means that signals such as SIGPIPE are not ignored by default
4222 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004308- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4309 position when calling `truncate()`. It would previously change the file
4310 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004311 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00004313- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004314 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4315 archive. The new implementation is significantly faster and can be wrapped in
4316 a :class:`io.BufferedReader` object for more speedups. It also solves an
4317 issue where interleaved calls to `read()` and `readline()` give wrong results.
4318 Patch by Nir Aides.

Brett Cannon69194272009-07-20 04:23:48 +00004653- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00004654 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4655 PyPycLoader inherit from this class and provide implementations in relation to
4656 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00004657
Brett Cannon64ef00f2009-07-20 03:19:18 +00004658- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
4659 the documentation said it did even though the code in PyLoader relied on the
4660 abstract method required by ResourceLoader.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004715- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004716 compared to other unix systems. In particular, os.getgroups() does not reflect
4717 any changes made using os.setgroups() but basicly always returns the same
4718 information as the id command. os.getgroups() can now return more than 16
4719 groups on MacOSX.
Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004720

Georg Brandl62069d32010-07-31 08:56:11 +00004744- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
4745 Prior to this change, timezone adjustment in utctimetuple() could produce
4746 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4750 directive. When the ``%z`` directive is present in the format string, an
4751 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4752 ``datetime.timezone`` instance constructed from the parsed offset. If both
4753 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4754 name, but ``%Z`` data without ``%z`` is discarded.

Georg Brandl62069d32010-07-31 08:56:11 +00004757 implementing ``datetime.tzinfo`` interface. Instances of the new class,
4758 ``datetime.timezone``, return fixed name and UTC offset from their
4759 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4760 returns ``None``. A class attribute, ``utc`` contains an instance
4761 representing the UTC timezone. Original patch by Rafe Kaplan.

Antoine Pitrou61f77b52009-05-24 15:46:13 +00005285- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5286 than an int, which makes some operations possible under 64-bit Linux (e.g.
5287 DN_MULTISHOT with F_NOTIFY).
5288
Antoine Pitrou716c4442009-05-23 19:04:03 +00005289- Issue #5761: Add the name of the underlying file to the repr() of various

5294
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005295- Issue #1983: Fix functions taking or returning a process identifier to use
5296 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5297 a process identifier type wider than the standard C integer type.
5298

5310
Antoine Pitroue4501852009-05-14 18:55:55 +00005311- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5312 library. This means, for example, that opening an UTF-16 text file in
5313 append mode doesn't add a BOM at the end of the file if the file isn't
5314 empty.
5315
R. David Murray74b89242009-05-13 17:33:03 +00005316- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5317 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5318 corrects a pydoc regression.
5319
Georg Brandl5f90d792010-08-01 22:31:05 +00005320- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005321 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005363
5364Core and Builtins
5365-----------------
5366
Mark Dickinson865e01a2009-05-07 16:37:01 +00005367- Issue #5914: Add new C API function PyOS_string_to_double, and
5368 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5369
Eric Smith741191f2009-05-06 13:08:15 +00005370- Issue #3382: float.__format__, complex.__format__, and %-formatting
5371 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5372 affects nan -> NAN and inf -> INF.
5373
Mark Hammond5a607a32009-05-06 08:04:54 +00005374- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5375 in all operations, including splitdrive, split, etc. splitunc() now issues
5376 a PendingDeprecation warning.
5377
Eric Smith63376222009-05-05 14:04:18 +00005378- Issue #5920: For float.__format__, change the behavior with the
5379 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5380 to be like 'g' but with at least one decimal point and with a
5381 default precision of 12. Previously, the behavior the same but with
5382 a default precision of 6. This more closely matches str(), and
5383 reduces surprises when adding alignment flags to the empty
5384 presentation type. This also affects the new complex.__format__ in
5385 the same way.
5386
Martin v. Löwis011e8422009-05-05 04:43:17 +00005387- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5388
R. David Murrayb18500d2009-05-04 22:59:07 +00005389- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5390 shadowed by classtype's, even if it was None. property now
5391 inserts the __doc__ into the subclass instance __dict__.
5392
Antoine Pitrou244651a2009-05-04 18:56:13 +00005393- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5394 sequences. Patch by Nick Barnes and Victor Stinner.
5395
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005396- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005397
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005398- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5399 received a new method, detach(). detach() disconnects the underlying stream
5400 from the buffer or text IO and returns it.
5401
Mark Dickinson33841c32009-05-01 15:37:04 +00005402- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5403 floats with absolute value over 1e50. Also remove length
5404 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5405 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005406
Eric Smith741191f2009-05-06 13:08:15 +00005407- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005408 format(complex(1, 2./3), '.5') now produces a sensible result.
5409
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005410- Issue #5864: Fix empty format code formatting for floats so that it
5411 never gives more than the requested number of significant digits.
5412
Eric Smith6dc46f52009-04-27 20:39:49 +00005413- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5414 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5415
Eric Smithcc32a112009-04-26 21:35:14 +00005416- Issue #5835: Deprecate PyOS_ascii_formatd.
5417
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005418- Issue #4971: Fix titlecase for characters that are their own
5419 titlecase, but not their own uppercase.
5420
Benjamin Peterson193152c2009-04-25 01:08:45 +00005421- Issue #5283: Setting __class__ in __del__ caused a segfault.
5422
Mark Dickinsonad476da2009-04-23 19:14:16 +00005423- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5424 z involves nans, infs or negative zeros.
5425
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005426- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005427
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005428- Issue #1869 (and many duplicates): make round(x, n) correctly
5429 rounded for a float x, by using the decimal <-> binary conversions
5430 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5431 consistently agrees with format(x, '.2f').
5432
Benjamin Petersonae937c02009-04-18 20:54:08 +00005433- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5434 some builtin types.
5435
Eric Smith0923d1d2009-04-16 20:16:10 +00005436- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5437
Eric Smith35e84722009-04-16 20:21:28 +00005438- Issue #5515: str.format() type 'n' combined with commas and leading
5439 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005440
5441- Implement PEP 378, Format Specifier for Thousands Separator, for
5442 floats.
5443
Mark Dickinson3370cce2009-04-17 22:40:53 +00005444- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005445 1e11, not 1e12. This avoids printing 13 significant digits in
5446 situations where only 12 of them are correct. Example problem
5447 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5448 long time.)
5449
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005450- Issue #1580: On most platforms, use a 'short' float repr: for a
5451 finite float x, repr(x) now outputs a string based on the shortest
5452 sequence of decimal digits that rounds to x. Previous behaviour was
5453 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005454 Another minor difference is that the new repr switches to
5455 exponential notation at 1e16 instead of the previous 1e17; this
5456 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005457
5458 There's a new sys attribute sys.float_repr_style, which takes
5459 the value 'short' to indicate that we're using short float repr,
5460 and 'legacy' if the short float repr isn't available for one
5461 reason or another.
5462
5463 The float repr change involves incorporating David Gay's 'perfect
5464 rounding' code into the Python core (it's in Python/dtoa.c). As a
5465 secondary consequence, all string-to-float and float-to-string
5466 conversions (including all float formatting operations) will be
5467 correctly rounded on these platforms.
5468
Georg Brandl5f90d792010-08-01 22:31:05 +00005469 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005470 this change does not apply.
5471
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005472- Issue #5759: float() didn't call __float__ on str subclasses.
5473
Georg Brandlabc38772009-04-12 15:51:51 +00005474- The string.maketrans() function is deprecated; there is a new static method
5475 maketrans() on the bytes and bytearray classes. This removes confusion about
5476 the types string.maketrans() is supposed to work with, and mirrors the
5477 methods available on the str class.
5478
R. David Murraydc6da8a2009-04-09 22:16:43 +00005479- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5480 its clarity and its speed.
5481
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005482- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005483 to avoid compiler warnings.
5484
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005485- Issue #3739: The unicode-internal encoder now reports the number of characters
5486 consumed like any other encoder (instead of the number of bytes).

5644
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005645- Issue #4688: Add a heuristic so that tuples and dicts containing only
5646 untrackable objects are not tracked by the garbage collector. This can
5647 reduce the size of collections and therefore the garbage collection overhead
5648 on long-running programs, depending on their particular use of datatypes.
5649
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005650- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5717
Lars Gustäbel42e00912009-03-22 20:34:29 +00005718- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
5719 forever on incomplete input. That caused tarfile.open() to hang when used
5720 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5721 partial bzip2 compressed data.
5722
Mark Dickinson79f52032009-03-17 23:12:51 +00005723- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou8043cf82009-01-09 19:54:29 +00005834 having been closed (for instance, a read() call could return some
5835 previously buffered data). Patch by Dmitry Vasiliev.
5836
Antoine Pitrou05608432009-01-09 18:53:14 +00005837- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5838 flag to work properly. Furthermore, when specifying -u, the text stdout
5839 and stderr streams have line-by-line buffering enabled (the default being
5840 to buffer arbitrary chunks of data).
5841
Raymond Hettinger35631532009-01-09 03:58:09 +00005842- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5843 instead of ints (reducing its size from 4 to 8 times thereby reducing
5844 Python's overall memory).
5845
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005846- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5847 an existing .py counterpart, override the co_filename attributes of all
5848 code objects if the original filename is obsolete (which can happen if the
5849 file has been renamed, moved, or if it is accessed through different paths).

5853 one byte. Also fixes the meaning of len() so that it returns the number of
5854 items, rather than the size in bytes.
5855
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005856- Issue #4075: Use OutputDebugStringW in Py_FatalError.

6243
Antoine Pitrou08838b62009-01-21 00:55:13 +00006244- Issue #5008: When a file is opened in append mode with the new IO library,
6245 do an explicit seek to the end of file (so that e.g. tell() returns the
6246 file size rather than 0). This is consistent with the behaviour of the

6277 appropriately when it is being used via socket.makefile() objects
6278 rather than delaying the close by waiting for garbage collection to do it.
6279
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006280- Issue #1696199: Add collections.Counter() for rapid and convenient
