Ned Deily657b2de2011-06-28 19:51:30 -0700676- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
677 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
678 interpreter process. This could cause failures in non-Distutils subprocesses
679 and was unreliable since tests or user programs could modify the interpreter
680 environment after Distutils set it. Instead, have Distutils set the the
681 deployment target only in the environment of each build subprocess. It is
682 still possible to globally override the default by setting
683 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
684 greater or equal to the default value, the value with which the interpreter

Victor Stinnerf933e1a2010-10-20 22:58:25 +00002575 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002576 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem

2580 filenames encoded to the filesystem encoding with the surrogateescape error

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002958- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other

2960 Py_Initialize().
2961
Georg Brandl27a28582010-10-10 09:49:21 +00002962- All SyntaxErrors now have a column offset and therefore a caret when the error

Brett Cannonbc2eff32010-09-19 21:39:02 +00002965- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the

Nick Coghlan37ee8502010-12-03 14:26:13 +00002968- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00002971- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2972 with a non-empty format string. This is an effort to future-proof user
2973 code. If a derived class does not currently implement __format__ but later
2974 adds its own __format__, it would most likely break user code that had
2975 supplied a format string. This will be changed to a DeprecationWaring in
2976 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002978- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2979 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2980 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 +00002982- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2983 functions from the libc caused the methods .upper() and lower() to become
2984 locale aware and created subtly wrong results.
2985
Georg Brandl27a28582010-10-10 09:49:21 +00002986- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002989- Issue #4617: Previously it was illegal to delete a name from the local
2990 namespace if it occurs as a free variable in a nested block. This limitation
2991 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
2992
Georg Brandl27a28582010-10-10 09:49:21 +00002993- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2995 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2996 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00003031- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003032 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003033 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003034 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003059 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003141- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003142 it possible for the user to create self-referencing ordered dictionaries which
3143 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003144 approach of using weakref proxies so that reference cycles never get created

3153 sys.setfilesystemencoding() creates inconsistencies because it is unable to

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003170- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3171 still return the id of the parent process after it has exited. This process
3172 id may even have been reused by another unrelated process.
3173
Georg Brandl27a28582010-10-10 09:49:21 +00003174- Issue #9792: In case of connection failure, socket.create_connection() would

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003183- Updates to the random module:
3184
Georg Brandl27a28582010-10-10 09:49:21 +00003185 * Document which parts of the module are guaranteed to stay the same across
3186 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003187
Georg Brandl27a28582010-10-10 09:49:21 +00003188 * Update the seed() method to use all of the bits in a string instead of just
3189 the hash value. This makes better use of the seed value and assures the
3190 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003191
Georg Brandl27a28582010-10-10 09:49:21 +00003192 * Improved the random()-->integer algorithm used in choice(), shuffle(),

3347 return characters from the full Unicode range, even on narrow unicode builds
3348 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3349 in Python is that unicodedata.numeric() now returns the correct value for
3350 large code points, and repr() may consider more characters as printable.

3388 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003389
3390 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00003730- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003731 start byte and the continuation byte(s) are now considered invalid, instead of
3732 the number of bytes specified by the start byte. E.g.:
3733 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3734 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3735 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3736 returned a single u'\ufffd'.

3739 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".

3751 dealing with unary minus applied to a constant. The removed code was mutating
3752 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00003753
Victor Stinner554f3f02010-06-16 23:33:54 +00003754- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00003755 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00003756 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003757 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003758
Victor Stinner25e8ec42010-06-25 00:02:38 +00003759- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3760 "w*" format instead. Add tests for "w*" format.
3761
Victor Stinner06e49dd2010-06-13 18:21:50 +00003762- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003763 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003764 string formats.
3765
Georg Brandl62069d32010-07-31 08:56:11 +00003766- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003767 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3768 location of the raised exception.
3769
Victor Stinner313a1202010-06-11 23:56:51 +00003770- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3771 filenames and enable os.fsencode().
3772
Benjamin Peterson285a6892010-06-22 19:21:52 +00003773- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3774
Georg Brandl62069d32010-07-31 08:56:11 +00003775- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3776 interpreter with characters outside the Basic Multilingual Plane (higher than
3777 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003778
Georg Brandl62069d32010-07-31 08:56:11 +00003779- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3780 TypeError instead of giving a DeprecationWarning when a float is parsed using
3781 the 'L' code (for long long). (All other integer codes already raise
3782 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003783
Victor Stinner600d3be2010-06-10 12:00:55 +00003784- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3785 enable shortcuts for upper case encoding name. Add also a shortcut for
3786 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3787
Georg Brandl62069d32010-07-31 08:56:11 +00003788- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3789 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003790
3791- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003792 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003793 like bytearray.
3794
Georg Brandl62069d32010-07-31 08:56:11 +00003795- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003796 used anymore and it was never documented.
3797
Georg Brandl62069d32010-07-31 08:56:11 +00003798- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00003799
Georg Brandl62069d32010-07-31 08:56:11 +00003800- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3801 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003802
Georg Brandl62069d32010-07-31 08:56:11 +00003803- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3804 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3805 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3806 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003807
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003808- Issue #8748: Fix two issues with comparisons between complex and integer
3809 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003810 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3811 (2) The comparison raised an OverflowError for large integers, leading to
3812 unpredictable exceptions when combining integers and complex objects in sets
3813 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003814
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003815- Issue #8766: Initialize _warnings module before importing the first module.
3816 Fix a crash if an empty directory called "encodings" exists in sys.path.
3817
Victor Stinner9ca9c252010-05-19 16:53:30 +00003818- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003819 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003820 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003821
Georg Brandl62069d32010-07-31 08:56:11 +00003822- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3823 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003824
Victor Stinnerae6265f2010-05-15 16:27:27 +00003825- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3826 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003827 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003828 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003829
Victor Stinner59e62db2010-05-15 13:14:32 +00003830- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003831 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003832
Victor Stinnerb744ba12010-05-15 12:27:16 +00003833- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003834 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003835 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3836
Victor Stinner0964ee12010-04-30 16:48:45 +00003837- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003838 PyUnicode_FromString() to support surrogates in the filename and use the right
3839 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00003840
Georg Brandl8569e582010-05-19 20:57:08 +00003841- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3842
Georg Brandl62069d32010-07-31 08:56:11 +00003843- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003844
Benjamin Petersonfb886362010-04-24 18:21:17 +00003845- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3846 arguments.
3847
Victor Stinner14284c22010-04-23 12:02:30 +00003848- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003849 indirectly Python signal handlers anymore because mywrite() ignores exceptions

3946 similar optimization already existed which turned a list of constants into a

Georg Brandl62069d32010-07-31 08:56:11 +00004252 applications that use a lot of regular expressions and limits the impact of
4253 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00004662- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4663 InvalidOperation instead of returning False. (Comparisons involving a quiet
4664 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4665 signaling NaNs remain unhashable.

Georg Brandl62069d32010-07-31 08:56:11 +00004667- Issue #2531: Comparison operations between floats and Decimal instances now
4668 return a result based on the numeric values of the operands; previously they
4669 returned an arbitrary result based on the relative ordering of id(float) and
4670 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
4671 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00004672
Raymond Hettinger9c01e442010-04-03 10:32:58 +00004673- Added a subtract() method to collections.Counter().
4674
Barry Warsawd5f9bf52010-03-31 21:36:22 +00004675- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004676 argument `-` which tells it to read files to compile from stdin. Each line is
4677 read on demand and the named file is compiled immediately. (Original patch by
4678 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00004680- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00004684- Comparisons using one of <, <=, >, >= between a complex instance and a
4685 Fractions instance now raise TypeError instead of returning True/False. This
4686 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4687 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004730- The internals of the subprocess module on POSIX systems have been replaced by
4731 an extension module (_posixsubprocess) so that the fork()+exec() can be done
4732 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00004733
Georg Brandl62069d32010-07-31 08:56:11 +00004734- subprocess.Popen now has restore_signals and start_new_session features. The
4735 default of restore_signals=True is a new behavior compared to earlier Python
4736 versions. This means that signals such as SIGPIPE are not ignored by default
4737 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004823- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4824 position when calling `truncate()`. It would previously change the file
4825 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004826 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00004828- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004829 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4830 archive. The new implementation is significantly faster and can be wrapped in
4831 a :class:`io.BufferedReader` object for more speedups. It also solves an
4832 issue where interleaved calls to `read()` and `readline()` give wrong results.
4833 Patch by Nir Aides.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005230- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005231 compared to other unix systems. In particular, os.getgroups() does not reflect
5232 any changes made using os.setgroups() but basicly always returns the same
5233 information as the id command. os.getgroups() can now return more than 16
5234 groups on MacOSX.

5590 threads could return successfully while some Thread objects were still

5795 skipping every test on the class. The ClassTestSuite class has been removed.
5796
Martin v. Löwis70ccd162009-05-24 19:47:22 +00005797- Issue #6050: Don't fail extracting a directory from a zipfile if
5798 the directory already exists.
5799
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005800- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5801 than an int, which makes some operations possible under 64-bit Linux (e.g.
5802 DN_MULTISHOT with F_NOTIFY).
5803
Antoine Pitrou716c4442009-05-23 19:04:03 +00005804- Issue #5761: Add the name of the underlying file to the repr() of various

5808 by Musashi Tamura, tests by Marcin Bachry.
5809
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00005810- Issue #1983: Fix functions taking or returning a process identifier to use
5811 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
5812 a process identifier type wider than the standard C integer type.
5813
R. David Murray87e20742009-05-23 01:30:26 +00005814- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

5825
Antoine Pitroue4501852009-05-14 18:55:55 +00005826- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5827 library. This means, for example, that opening an UTF-16 text file in
5828 append mode doesn't add a BOM at the end of the file if the file isn't
5829 empty.
5830
R. David Murray74b89242009-05-13 17:33:03 +00005831- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
5832 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
5833 corrects a pydoc regression.
5834
Georg Brandl5f90d792010-08-01 22:31:05 +00005835- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005836 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00005878
5879Core and Builtins
5880-----------------
5881
Mark Dickinson865e01a2009-05-07 16:37:01 +00005882- Issue #5914: Add new C API function PyOS_string_to_double, and
5883 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5884
Eric Smith741191f2009-05-06 13:08:15 +00005885- Issue #3382: float.__format__, complex.__format__, and %-formatting
5886 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5887 affects nan -> NAN and inf -> INF.
5888
Mark Hammond5a607a32009-05-06 08:04:54 +00005889- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5890 in all operations, including splitdrive, split, etc. splitunc() now issues
5891 a PendingDeprecation warning.
5892
Eric Smith63376222009-05-05 14:04:18 +00005893- Issue #5920: For float.__format__, change the behavior with the
5894 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5895 to be like 'g' but with at least one decimal point and with a
5896 default precision of 12. Previously, the behavior the same but with
5897 a default precision of 6. This more closely matches str(), and
5898 reduces surprises when adding alignment flags to the empty
5899 presentation type. This also affects the new complex.__format__ in
5900 the same way.
5901
Martin v. Löwis011e8422009-05-05 04:43:17 +00005902- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5903
R. David Murrayb18500d2009-05-04 22:59:07 +00005904- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5905 shadowed by classtype's, even if it was None. property now
5906 inserts the __doc__ into the subclass instance __dict__.
5907
Antoine Pitrou244651a2009-05-04 18:56:13 +00005908- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5909 sequences. Patch by Nick Barnes and Victor Stinner.
5910
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005911- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005912
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005913- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5914 received a new method, detach(). detach() disconnects the underlying stream
5915 from the buffer or text IO and returns it.
5916
Mark Dickinson33841c32009-05-01 15:37:04 +00005917- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5918 floats with absolute value over 1e50. Also remove length
5919 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5920 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005921
Eric Smith741191f2009-05-06 13:08:15 +00005922- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005923 format(complex(1, 2./3), '.5') now produces a sensible result.
5924
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005925- Issue #5864: Fix empty format code formatting for floats so that it
5926 never gives more than the requested number of significant digits.
5927
Eric Smith6dc46f52009-04-27 20:39:49 +00005928- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5929 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5930
Eric Smithcc32a112009-04-26 21:35:14 +00005931- Issue #5835: Deprecate PyOS_ascii_formatd.
5932
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005933- Issue #4971: Fix titlecase for characters that are their own
5934 titlecase, but not their own uppercase.
5935
Benjamin Peterson193152c2009-04-25 01:08:45 +00005936- Issue #5283: Setting __class__ in __del__ caused a segfault.
5937
Mark Dickinsonad476da2009-04-23 19:14:16 +00005938- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5939 z involves nans, infs or negative zeros.
5940
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005941- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005942
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005943- Issue #1869 (and many duplicates): make round(x, n) correctly
5944 rounded for a float x, by using the decimal <-> binary conversions
5945 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5946 consistently agrees with format(x, '.2f').
5947
Benjamin Petersonae937c02009-04-18 20:54:08 +00005948- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5949 some builtin types.
5950
Eric Smith0923d1d2009-04-16 20:16:10 +00005951- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5952
Eric Smith35e84722009-04-16 20:21:28 +00005953- Issue #5515: str.format() type 'n' combined with commas and leading
5954 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005955
5956- Implement PEP 378, Format Specifier for Thousands Separator, for
5957 floats.
5958
Mark Dickinson3370cce2009-04-17 22:40:53 +00005959- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005960 1e11, not 1e12. This avoids printing 13 significant digits in
5961 situations where only 12 of them are correct. Example problem
5962 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5963 long time.)
5964
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005965- Issue #1580: On most platforms, use a 'short' float repr: for a
5966 finite float x, repr(x) now outputs a string based on the shortest
5967 sequence of decimal digits that rounds to x. Previous behaviour was
5968 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005969 Another minor difference is that the new repr switches to
5970 exponential notation at 1e16 instead of the previous 1e17; this
5971 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005972
5973 There's a new sys attribute sys.float_repr_style, which takes
5974 the value 'short' to indicate that we're using short float repr,
5975 and 'legacy' if the short float repr isn't available for one
5976 reason or another.
5977
5978 The float repr change involves incorporating David Gay's 'perfect
5979 rounding' code into the Python core (it's in Python/dtoa.c). As a
5980 secondary consequence, all string-to-float and float-to-string
5981 conversions (including all float formatting operations) will be
5982 correctly rounded on these platforms.
5983
Georg Brandl5f90d792010-08-01 22:31:05 +00005984 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005985 this change does not apply.
5986
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005987- Issue #5759: float() didn't call __float__ on str subclasses.
5988
Georg Brandlabc38772009-04-12 15:51:51 +00005989- The string.maketrans() function is deprecated; there is a new static method
5990 maketrans() on the bytes and bytearray classes. This removes confusion about
5991 the types string.maketrans() is supposed to work with, and mirrors the
5992 methods available on the str class.
5993
R. David Murraydc6da8a2009-04-09 22:16:43 +00005994- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5995 its clarity and its speed.
5996
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005997- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005998 to avoid compiler warnings.
5999
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006000- Issue #3739: The unicode-internal encoder now reports the number of characters
6001 consumed like any other encoder (instead of the number of bytes).

6158 the end sys.path, for compatibility with the system install of Python.
6159
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006160- Issue #4688: Add a heuristic so that tuples and dicts containing only
6161 untrackable objects are not tracked by the garbage collector. This can
6162 reduce the size of collections and therefore the garbage collection overhead
6163 on long-running programs, depending on their particular use of datatypes.

6232
Lars Gustäbel42e00912009-03-22 20:34:29 +00006233- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6234 forever on incomplete input. That caused tarfile.open() to hang when used
6235 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6236 partial bzip2 compressed data.
6237
Mark Dickinson79f52032009-03-17 23:12:51 +00006238- Issue #2110: Add support for thousands separator and 'n' type

Antoine Pitrou8043cf82009-01-09 19:54:29 +00006349 having been closed (for instance, a read() call could return some
6350 previously buffered data). Patch by Dmitry Vasiliev.
6351
Antoine Pitrou05608432009-01-09 18:53:14 +00006352- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6353 flag to work properly. Furthermore, when specifying -u, the text stdout
6354 and stderr streams have line-by-line buffering enabled (the default being
6355 to buffer arbitrary chunks of data).
6356
Raymond Hettinger35631532009-01-09 03:58:09 +00006357- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6358 instead of ints (reducing its size from 4 to 8 times thereby reducing
6359 Python's overall memory).
6360
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006361- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6362 an existing .py counterpart, override the co_filename attributes of all
6363 code objects if the original filename is obsolete (which can happen if the
6364 file has been renamed, moved, or if it is accessed through different paths).

6368 one byte. Also fixes the meaning of len() so that it returns the number of
6369 items, rather than the size in bytes.
6370
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006371- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Antoine Pitrou08838b62009-01-21 00:55:13 +00006759- Issue #5008: When a file is opened in append mode with the new IO library,
6760 do an explicit seek to the end of file (so that e.g. tell() returns the

6792 appropriately when it is being used via socket.makefile() objects
6793 rather than delaying the close by waiting for garbage collection to do it.
