1129 Distutils-based packages with C extension modules may fail because
1130 Apple has removed gcc-4.2, the version used to build python.org
1131 64-bit/32-bit Pythons. If the user does not explicitly override
1132 the default C compiler by setting the CC environment variable,
1133 Distutils will now attempt to compile extension modules with clang
1134 if gcc-4.2 is required but not found. Also as a convenience, if
1135 the user does explicitly set CC, substitute its value as the default
1136 compiler in the Distutils LDSHARED configuration variable for OS X.
1137 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1138 SDK, neither of which are available in Xcode 4. This change does not
1139 attempt to override settings to support their use with Xcode 4.)

1865
Ned Deily657b2de2011-06-28 19:51:30 -07001866- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1867 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1868 interpreter process. This could cause failures in non-Distutils subprocesses
1869 and was unreliable since tests or user programs could modify the interpreter
1870 environment after Distutils set it. Instead, have Distutils set the the
1871 deployment target only in the environment of each build subprocess. It is
1872 still possible to globally override the default by setting
1873 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1874 greater or equal to the default value, the value with which the interpreter

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00003053 filenames, at bootstrap, if the codec registry is not ready yet. It is still
3054 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)

3067 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00003068
3069- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00003070 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00003071 that for incoming headers which makes this behaviour now consistent in
3072 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00003168- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00003169 continuation line in the formatted value has no leading white space and looks
3170 like a header. Since Generator uses Header to format all headers, this check
3171 is made for all headers in any serialized message at serialization time. This
3172 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00003173
Antoine Pitrou67b212e2011-01-08 09:55:31 +00003174- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Éric Araujof0ab5d62011-05-29 03:43:59 +02003181 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00003182 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00003183
Éric Araujof0ab5d62011-05-29 03:43:59 +02003184- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00003185 rfc2047-encoding header values with embedded newlines, leaving them without
3186 folding whitespace. It now uses the continuation_ws, as it does for
3187 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00003189- Issue #1777412, #10827: Changed the rules for 2-digit years. The
3190 time.asctime(), time.ctime() and time.strftime() functions will now format

3192 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
3193 supported by the OS. With Visual Studio or on Solaris, the year is limited to
3194 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

4215 Py_Initialize().
4216
Georg Brandl27a28582010-10-10 09:49:21 +00004217- All SyntaxErrors now have a column offset and therefore a caret when the error

Nick Coghlan37ee8502010-12-03 14:26:13 +00004223- Issue #9213: The range type_items now provides index() and count() methods, to

4227 with a non-empty format string. This is an effort to future-proof user
4228 code. If a derived class does not currently implement __format__ but later
4229 adds its own __format__, it would most likely break user code that had
4230 supplied a format string. This will be changed to a DeprecationWaring in
4231 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00004233- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

4235 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 +00004237- Issue #9210: Configure option --with-wctype-functions was removed. Using the
4238 functions from the libc caused the methods .upper() and lower() to become
4239 locale aware and created subtly wrong results.
4240
Georg Brandl27a28582010-10-10 09:49:21 +00004241- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
4242 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00004243
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00004244- Issue #4617: Previously it was illegal to delete a name from the local
4245 namespace if it occurs as a free variable in a nested block. This limitation
4246 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
4247
Georg Brandl27a28582010-10-10 09:49:21 +00004248- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
4249 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
4250 Also, the "backslashreplace" error handler now joins surrogate pairs into a
4251 single character on UCS-2 builds.

4255 memoryview), and gain support for the context management protocol.
4256
Antoine Pitrou079ce542010-09-08 12:37:10 +00004257- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00004286- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00004287 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00004288 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00004289 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00004314 retry the select() loop instead of bailing out. This is because select() can
4315 incorrectly report a socket as ready for reading (for example, if it received
4316 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00004396- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00004397 it possible for the user to create self-referencing ordered dictionaries which
4398 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00004399 approach of using weakref proxies so that reference cycles never get created
4400 in the first place.

Georg Brandl27a28582010-10-10 09:49:21 +00004443 * Update the seed() method to use all of the bits in a string instead of just
4444 the hash value. This makes better use of the seed value and assures the
4445 seeding is platform independent. Issue #7889.

Georg Brandl27a28582010-10-10 09:49:21 +00004447 * Improved the random()-->integer algorithm used in choice(), shuffle(),
4448 sample(), randrange(), and randint(). Formerly, it used int(n*random())
4449 which has a slight bias whenever n is not a power of two. Issue #9025.

4451 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00004470- hashlib has two new constant attributes: algorithms_guaranteed and

4472 guaranteed to exist in all Python implementations and the names of hash
4473 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00004565- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
4566 the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our

Georg Brandl649971e2010-09-05 17:06:50 +00004578- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
4579 now removed, since their effect was inexistent in 3.x (the default encoding is
4580 hardcoded to utf-8 and cannot be changed).
Antoine Pitroufce7fd62010-09-01 18:54:56 +00004581
Antoine Pitroub0fa8312010-09-01 15:10:12 +00004582- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API

Georg Brandl649971e2010-09-05 17:06:50 +00004585- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
4586 platforms. Previously, it inlined only when using Microsoft Visual C.
Daniel Stutzbacha606faa2010-08-31 19:51:07 +00004587

4602 return characters from the full Unicode range, even on narrow unicode builds
4603 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
4604 in Python is that unicodedata.numeric() now returns the correct value for
4605 large code points, and repr() may consider more characters as printable.
4606
Victor Stinner6c00c142010-08-17 23:37:11 +00004607- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
4608 as a unicode object, instead of a byte string. Function needed to support
4609 unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
4610 function.

4615
Georg Brandl649971e2010-09-05 17:06:50 +00004616- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
4617 the module file to be executed with the -m command line option.
Nick Coghland26c18a2010-08-17 13:06:11 +00004618

4620 write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
Victor Stinner79766632010-08-16 17:36:42 +00004621 sys.stderr.
4622
Victor Stinner47fcb5b2010-08-13 23:59:58 +00004623- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
Georg Brandl649971e2010-09-05 17:06:50 +00004624 decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
4625 objects are output as-is.
Victor Stinner47fcb5b2010-08-13 23:59:58 +00004626
Georg Brandl649971e2010-09-05 17:06:50 +00004627- Issue #9203: Computed gotos are now enabled by default on supported compilers
4628 (which are detected by the configure script). They can still be disable
4629 selectively by specifying --without-computed-gotos.
Antoine Pitrou042b1282010-08-13 21:15:58 +00004630
Georg Brandl649971e2010-09-05 17:06:50 +00004631- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
4632 use PyUnicode_FromFormatV() to format the warning message.
Victor Stinner4a2b7a12010-08-13 14:03:48 +00004633
Georg Brandl649971e2010-09-05 17:06:50 +00004634- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
4635 array.

Georg Brandl649971e2010-09-05 17:06:50 +00004639- Issue #9337: The str() of a float or complex number is now identical to its
4640 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00004641
Georg Brandl649971e2010-09-05 17:06:50 +00004642- Issue #9416: Fix some issues with complex formatting where the output with no
4643 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00004644
4645 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
4646 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

4987 the number of bytes specified by the start byte. E.g.:

4989 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4990 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4991 returned a single u'\ufffd'.

Victor Stinner25e8ec42010-06-25 00:02:38 +00005014- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
5015 "w*" format instead. Add tests for "w*" format.
5016
Victor Stinner06e49dd2010-06-13 18:21:50 +00005017- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00005018 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00005019 string formats.
5020
Georg Brandl62069d32010-07-31 08:56:11 +00005021- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00005022 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
5023 location of the raised exception.
5024
Victor Stinner313a1202010-06-11 23:56:51 +00005025- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
5026 filenames and enable os.fsencode().
5027
Benjamin Peterson285a6892010-06-22 19:21:52 +00005028- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
5029
Georg Brandl62069d32010-07-31 08:56:11 +00005030- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
5031 interpreter with characters outside the Basic Multilingual Plane (higher than
5032 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00005033
Georg Brandl62069d32010-07-31 08:56:11 +00005034- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
5035 TypeError instead of giving a DeprecationWarning when a float is parsed using
5036 the 'L' code (for long long). (All other integer codes already raise
5037 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00005038
Victor Stinner600d3be2010-06-10 12:00:55 +00005039- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
5040 enable shortcuts for upper case encoding name. Add also a shortcut for
5041 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
5042
Georg Brandl62069d32010-07-31 08:56:11 +00005043- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
5044 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00005045
5046- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00005047 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00005048 like bytearray.
5049
Georg Brandl62069d32010-07-31 08:56:11 +00005050- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00005051 used anymore and it was never documented.
5052
Georg Brandl62069d32010-07-31 08:56:11 +00005053- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00005054

5056 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00005057
Georg Brandl62069d32010-07-31 08:56:11 +00005058- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
5059 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
5060 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
5061 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00005062
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005063- Issue #8748: Fix two issues with comparisons between complex and integer
5064 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00005065 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
5066 (2) The comparison raised an OverflowError for large integers, leading to
5067 unpredictable exceptions when combining integers and complex objects in sets
5068 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00005069
Victor Stinner7d79b8b2010-05-19 20:40:50 +00005070- Issue #8766: Initialize _warnings module before importing the first module.
5071 Fix a crash if an empty directory called "encodings" exists in sys.path.
5072
Victor Stinner9ca9c252010-05-19 16:53:30 +00005073- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00005074 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00005075 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00005076
Georg Brandl62069d32010-07-31 08:56:11 +00005077- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
5078 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00005079
Victor Stinnerae6265f2010-05-15 16:27:27 +00005080- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
5081 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00005082 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00005083 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00005084
Victor Stinner59e62db2010-05-15 13:14:32 +00005085- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00005086 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00005087
Victor Stinnerb744ba12010-05-15 12:27:16 +00005088- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00005089 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00005090 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
5091
Victor Stinner0964ee12010-04-30 16:48:45 +00005092- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00005093 PyUnicode_FromString() to support surrogates in the filename and use the right
5094 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00005095
Georg Brandl8569e582010-05-19 20:57:08 +00005096- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
5097
Georg Brandl62069d32010-07-31 08:56:11 +00005098- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00005099
Benjamin Petersonfb886362010-04-24 18:21:17 +00005100- Issue #8419: Prevent the dict constructor from accepting non-string keyword
5101 arguments.
5102
Victor Stinner14284c22010-04-23 12:02:30 +00005103- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00005104 indirectly Python signal handlers anymore because mywrite() ignores exceptions
5105 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00005106
Victor Stinner31be90b2010-04-22 19:38:16 +00005107- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

Victor Stinner31be90b2010-04-22 19:38:16 +00005109
Georg Brandl62069d32010-07-31 08:56:11 +00005110- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
5111 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00005112
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00005113- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00005114 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
5115 compared to the dynamic memory allocation fallback. Patch by Charles-François
5116 Natali.
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00005117
Benjamin Peterson8380dd52010-04-16 22:51:37 +00005118- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
5119 passed to bytes or bytearray.

5124 changed.
5125
Georg Brandl62069d32010-07-31 08:56:11 +00005126- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
5127 64-bit machines. The shift count for either left or right shift is permitted
5128 to be up to sys.maxsize.

Mark Dickinsond59b4162010-03-13 11:34:40 +00005144- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
Georg Brandl62069d32010-07-31 08:56:11 +00005145 PyMemberDefs could produce an internal error; raise TypeError instead.
Mark Dickinsond59b4162010-03-13 11:34:40 +00005146
Mark Dickinsonf673f0c2010-03-13 09:48:39 +00005147- Issue #7845: Rich comparison methods on the complex type now return
5148 NotImplemented rather than raising a TypeError when comparing with an
5149 incompatible type; this allows user-defined classes to implement their own
5150 comparisons with complex.
5151
Victor Stinner52f6dd72010-03-12 14:45:56 +00005152- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
5153 (SIGINT). If an error occurs while importing the site module, the error is

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00005197- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00005198 where the right hand operand is a set of constants, by turning the set into a
5199 frozenset and pre-building it as a constant. The comparison operation is made
5200 against the constant instead of building a new set each time it is executed (a
5201 similar optimization already existed which turned a list of constants into a
5202 pre-built tuple). Patch and additional tests by Dave Malcolm.

5209 including: (1) a serious 'wrong output' bug that could occur for long (> 40
5210 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
5211 parsing certain long numeric strings corresponding to subnormal values, (3) a
5212 memory leak for some values large enough to cause overflow, and (4) a number
5213 of flaws that could lead to incorrectly rounded results.

5398 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
5399 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00005400 to match the behaviour of the other integer format codes.

Antoine Pitrou3060c452010-08-13 16:27:38 +00005505 simply clearing the entire cache on overflow to forgetting the least recently
5506 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00005507 applications that use a lot of regular expressions and limits the impact of
5508 the performance hit anytime the cache is exceeded.

Georg Brandl62069d32010-07-31 08:56:11 +00005762- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
5763 operation raises multiple signals and more than one of those signals is
5764 trapped, the specification determines the order in which the signals should be
5765 handled. In many cases this order wasn't being followed, leading to the wrong
5766 Python exception being raised.

Georg Brandl62069d32010-07-31 08:56:11 +00005805- Issue #8524: When creating an SSL socket, the timeout value of the original
5806 socket wasn't retained (instead, a socket with a positive timeout would be
5807 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00005808
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00005809- Issue #5103: SSL handshake would ignore the socket timeout and block

Barry Warsawd5f9bf52010-03-31 21:36:22 +00005930- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00005931 argument `-` which tells it to read files to compile from stdin. Each line is
5932 read on demand and the named file is compiled immediately. (Original patch by
5933 Piotr Ożarowski).

Georg Brandl62069d32010-07-31 08:56:11 +00005939- Comparisons using one of <, <=, >, >= between a complex instance and a
5940 Fractions instance now raise TypeError instead of returning True/False. This
5941 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5942 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005989- subprocess.Popen now has restore_signals and start_new_session features. The
5990 default of restore_signals=True is a new behavior compared to earlier Python
5991 versions. This means that signals such as SIGPIPE are not ignored by default

Antoine Pitroua32f9a22010-01-27 21:18:57 +00006083- Issue #7610: Reworked implementation of the internal

Georg Brandl62069d32010-07-31 08:56:11 +00006085 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02006086 a ``io.BufferedReader`` object for more speedups. It also solves an
Georg Brandl62069d32010-07-31 08:56:11 +00006087 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00006423- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00006424 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
6425 PyPycLoader inherit from this class and provide implementations in relation to
6426 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00006485- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00006486 compared to other unix systems. In particular, os.getgroups() does not reflect
6487 any changes made using os.setgroups() but basicly always returns the same
6488 information as the id command. os.getgroups() can now return more than 16
6489 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00006514- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
6515 Prior to this change, timezone adjustment in utctimetuple() could produce
6516 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

Georg Brandl62069d32010-07-31 08:56:11 +00006519- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
6520 directive. When the ``%z`` directive is present in the format string, an
6521 aware ``datetime`` object is returned with ``tzinfo`` bound to a
6522 ``datetime.timezone`` instance constructed from the parsed offset. If both
6523 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
6524 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00006526- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00006527 implementing ``datetime.tzinfo`` interface. Instances of the new class,
6528 ``datetime.timezone``, return fixed name and UTC offset from their
6529 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
6530 returns ``None``. A class attribute, ``utc`` contains an instance
6531 representing the UTC timezone. Original patch by Rafe Kaplan.

6548 with an improved 'binary-split' algorithm that uses fewer multiplications and
6549 allows many of the multiplications to be performed using plain C integer
6550 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

6557 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00006558 the result is now always correctly rounded, and is equivalent to ``td /

6568 integer format code, struct.pack first attempts to convert the non-integer
6569 using its __index__ method. If that method is non-existent or raises

Mark Dickinson865e01a2009-05-07 16:37:01 +00007137- Issue #5914: Add new C API function PyOS_string_to_double, and
7138 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.

Eric Smith741191f2009-05-06 13:08:15 +00007140- Issue #3382: float.__format__, complex.__format__, and %-formatting

7147
Eric Smith63376222009-05-05 14:04:18 +00007148- Issue #5920: For float.__format__, change the behavior with the

7150 to be like 'g' but with at least one decimal point and with a
7151 default precision of 12. Previously, the behavior the same but with
7152 a default precision of 6. This more closely matches str(), and
7153 reduces surprises when adding alignment flags to the empty
7154 presentation type. This also affects the new complex.__format__ in
7155 the same way.

R. David Murrayb18500d2009-05-04 22:59:07 +00007159- Issue #5890: in subclasses of 'property' the __doc__ attribute was
7160 shadowed by classtype's, even if it was None. property now
7161 inserts the __doc__ into the subclass instance __dict__.
7162
Antoine Pitrou244651a2009-05-04 18:56:13 +00007163- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Benjamin Petersond2e0c792009-05-01 20:40:59 +00007168- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
7169 received a new method, detach(). detach() disconnects the underlying stream
7170 from the buffer or text IO and returns it.
7171
Mark Dickinson33841c32009-05-01 15:37:04 +00007172- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
7173 floats with absolute value over 1e50. Also remove length
7174 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
7175 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00007177- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00007178 format(complex(1, 2./3), '.5') now produces a sensible result.
7179
Mark Dickinsond3ca5572009-04-29 18:47:07 +00007180- Issue #5864: Fix empty format code formatting for floats so that it
7181 never gives more than the requested number of significant digits.
7182
Eric Smith6dc46f52009-04-27 20:39:49 +00007183- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

7194 z involves nans, infs or negative zeros.
7195
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00007196- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00007197
Mark Dickinsone6a076d2009-04-18 11:48:33 +00007198- Issue #1869 (and many duplicates): make round(x, n) correctly
7199 rounded for a float x, by using the decimal <-> binary conversions
7200 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
7201 consistently agrees with format(x, '.2f').
7202
Benjamin Petersonae937c02009-04-18 20:54:08 +00007203- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
7204 some builtin types.
7205
Eric Smith0923d1d2009-04-16 20:16:10 +00007206- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
7207
Eric Smith35e84722009-04-16 20:21:28 +00007208- Issue #5515: str.format() type 'n' combined with commas and leading
7209 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00007210
7211- Implement PEP 378, Format Specifier for Thousands Separator, for
7212 floats.
7213
Mark Dickinson3370cce2009-04-17 22:40:53 +00007214- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007215 1e11, not 1e12. This avoids printing 13 significant digits in
7216 situations where only 12 of them are correct. Example problem
7217 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
7218 long time.)
7219
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007220- Issue #1580: On most platforms, use a 'short' float repr: for a
7221 finite float x, repr(x) now outputs a string based on the shortest
7222 sequence of decimal digits that rounds to x. Previous behaviour was
7223 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00007224 Another minor difference is that the new repr switches to
7225 exponential notation at 1e16 instead of the previous 1e17; this
7226 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007227
7228 There's a new sys attribute sys.float_repr_style, which takes
7229 the value 'short' to indicate that we're using short float repr,
7230 and 'legacy' if the short float repr isn't available for one
7231 reason or another.
7232
7233 The float repr change involves incorporating David Gay's 'perfect
7234 rounding' code into the Python core (it's in Python/dtoa.c). As a
7235 secondary consequence, all string-to-float and float-to-string
7236 conversions (including all float formatting operations) will be
7237 correctly rounded on these platforms.
7238
Georg Brandl5f90d792010-08-01 22:31:05 +00007239 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00007240 this change does not apply.
7241
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00007242- Issue #5759: float() didn't call __float__ on str subclasses.
7243
Georg Brandlabc38772009-04-12 15:51:51 +00007244- The string.maketrans() function is deprecated; there is a new static method
7245 maketrans() on the bytes and bytearray classes. This removes confusion about
7246 the types string.maketrans() is supposed to work with, and mirrors the
7247 methods available on the str class.
7248
R. David Murraydc6da8a2009-04-09 22:16:43 +00007249- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00007255- Issue #3739: The unicode-internal encoder now reports the number of characters

7416 untrackable objects are not tracked by the garbage collector. This can
7417 reduce the size of collections and therefore the garbage collection overhead
7418 on long-running programs, depending on their particular use of datatypes.

7425 2**15 for the internal representation of integers, for performance
7426 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
7427 --enable-big-digits option to configure, which overrides the
7428 default. Add sys.int_info structseq to provide information about
7429 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00007541- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
7542 it now forces its argument to double before testing for infinity.
7543
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00007544- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
7545 returns a non-number type.
7546
Benjamin Peterson87618552009-02-08 15:00:52 +00007547- Issue #5182: Removed memoryview.__str__.
7548
Mark Dickinsonc008a172009-02-01 13:59:22 +00007549- Issue #1717: Removed builtin cmp() function, dropped tp_compare
7550 slot, the C API functions PyObject_Compare and PyUnicode_Compare and

7552 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00007553
Georg Brandl1cdd83c2009-04-05 20:24:29 +00007554- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00007555 were suppressing all exceptions. These include list() and bytearray().
7556
Mark Dickinson1124e712009-01-28 21:25:58 +00007557- Issue #4707: round(x, n) now returns an integer if x is an integer.
7558 Previously it returned a float.
7559
Antoine Pitroub52ec782009-01-25 16:34:23 +00007560- Issue #4753: By enabling a configure option named '--with-computed-gotos'
7561 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
7562 evaluation loop is compiled with a new dispatch mechanism which gives
7563 speedups of up to 20%, depending on the system, on various benchmarks.
7564
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00007565- Issue #4874: Most builtin decoders now reject unicode input.

7573 optional module state data.
7574
Mark Dickinson8055afd2009-01-17 10:04:45 +00007575- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00007576 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00007577
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00007578- Issue #4935: The overflow checking code in the expandtabs() method common
7579 to str, bytes and bytearray could be optimized away by the compiler, letting
7580 the interpreter segfault instead of raising an error.
7581
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00007582- Issue #3720: Fix a crash when an iterator modifies its class and removes its
7583 __next__ method.
7584
Mark Dickinsone5e298f2009-01-12 20:49:19 +00007585- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
7586 function no longer attempt to call the __long__ slot to convert an object
7587 to an integer. Only the __int__ and __trunc__ slots are examined.
7588
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00007589- Issue #4893: Use NT threading on CE.
7590

7592
Antoine Pitrouab868312009-01-10 15:40:25 +00007593- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
7594 common cases are optimized thanks to a dedicated fast path and a moderate
7595 amount of loop unrolling.
7596
Antoine Pitrou14b78f52009-01-09 22:27:08 +00007597- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
7598 collecting the oldest generation) so that allocating lots of objects without
7599 destroying them does not show quadratic performance. Based on a proposal by
7600 Martin von Löwis at
7601 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
7602
Vinay Sajip6268cbc2009-01-21 00:19:28 +00007603- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00007604 having been closed (for instance, a read() call could return some
7605 previously buffered data). Patch by Dmitry Vasiliev.
7606
Antoine Pitrou05608432009-01-09 18:53:14 +00007607- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
7608 flag to work properly. Furthermore, when specifying -u, the text stdout
7609 and stderr streams have line-by-line buffering enabled (the default being
7610 to buffer arbitrary chunks of data).
7611
Raymond Hettinger35631532009-01-09 03:58:09 +00007612- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
7613 instead of ints (reducing its size from 4 to 8 times thereby reducing
7614 Python's overall memory).
7615
Antoine Pitroud35cbf62009-01-06 19:02:24 +00007616- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
7617 an existing .py counterpart, override the co_filename attributes of all
7618 code objects if the original filename is obsolete (which can happen if the
7619 file has been renamed, moved, or if it is accessed through different paths).
7620 Patch by Ziga Seilnacht and Jean-Paul Calderone.
7621
Antoine Pitrouc3b39242009-01-03 16:59:18 +00007622- Issue #4580: Fix slicing of memoryviews when the item size is greater than
7623 one byte. Also fixes the meaning of len() so that it returns the number of
7624 items, rather than the size in bytes.
7625
Martin v. Löwis5c88d812009-01-02 20:47:48 +00007626- Issue #4075: Use OutputDebugStringW in Py_FatalError.
7627
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00007628- Issue #4747: When the terminal does not use utf-8, executing a script with
7629 non-ascii characters in its name could fail with a "SyntaxError: None" error.
7630
Georg Brandl65ce6ad2010-09-05 17:32:31 +00007631- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
7632 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00007633
Antoine Pitrou7ddda782009-01-01 15:35:33 +00007634- Issue #3680: Reference cycles created through a dict, set or deque iterator
7635 did not get collected.
7636
Nick Coghlanf1f2f682008-12-30 07:29:12 +00007637- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
7638 where the tp_hash and tp_dict slots are both NULL.
7639
Georg Brandlccc47b62008-12-28 11:44:14 +00007640- Issue #4759: None is now allowed as the first argument of
7641 bytearray.translate(). It was always allowed for bytes.translate().
7642
Skip Montanaro80072cb2008-12-23 03:51:14 +00007643- Added test case to ensure attempts to read from a file opened for writing
7644 fail.
7645
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00007646- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00007648- Issue #2183: Simplify and optimize bytecode for list, dict and set
7649 comprehensions. Original patch for list comprehensions by Neal Norwitz.
7650
Antoine Pitrou621601a2008-12-17 23:18:19 +00007651- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
7652 print elapsed times, not only when some objects are uncollectable /
7653 unreachable. Original patch by Neil Schemenauer.
7654
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00007655- Issue #3439: Add a bit_length method to int.
7656
Mark Dickinsonda2706b2008-12-11 18:03:03 +00007657- Issue #2173: When getting device encoding, check that return value of
7658 nl_langinfo is not the empty string. This was causing silent build
7659 failures on OS X.
7660
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00007661- Issue #4597: Fixed several opcodes that weren't always propagating
7662 exceptions.
7663
7664- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00007665 context manager returns a value that cannot be converted to a bool.
7666
Mark Dickinsonfd24b322008-12-06 15:33:31 +00007667- Issue #4445: Replace "sizeof(PyBytesObject)" with
7668 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
7669 bytes instances. On a typical machine this saves 3 bytes of memory
7670 (on average) per allocation of a bytes instance.
7671
Christian Heimesa872de52008-12-05 08:26:55 +00007672- Issue #4533: File read operation was dreadfully slow due to a slowly
7673 growing read buffer. Fixed by using the same growth rate algorithm as
7674 Python 2.x.
7675
Antoine Pitrou5504e892008-12-06 21:27:53 +00007676- Issue #4509: Various issues surrounding resize of bytearray objects to
7677 which there are buffer exports (e.g. memoryview instances).
7678
Georg Brandlf9734072008-12-07 15:30:06 +00007679- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
7680 method on file objects with closefd=False. The file descriptor is still
7681 kept open but the file object behaves like a closed file. The ``FileIO``
7682 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00007683
Antoine Pitroubc420402008-12-07 20:14:49 +00007684- Issue #4569: Interpreter crash when mutating a memoryview with an item size
7685 larger than 1.

7690
Walter Dörwaldc1651a02009-05-03 22:55:55 +00007691- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
7692 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
7693 step. This avoids problems with counting UTF-8 bytes that ignores the effect
7694 of using the replace error handler in PyUnicode_DecodeUTF8().

8297 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00008299- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
8300 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
8301 the same behaviour as test_ttkguionly (and now also test_tk) which is to
8302 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00008304- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00008305 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00008306 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00008308- Issue #5083: New 'gui' resource for regrtest.
