25 all possible file descriptors in the child process rather than just open
26 file descriptors. It now closes only the open fds if possible for the

38 code, to avoid timestamp collisions (especially on filesystems with a low
39 timestamp resolution) when checking for freshness of the bytecode.
40
Nick Coghlan1f7ce622012-01-13 21:43:40 +100041- PEP 380, Issue #11682: Add "yield from <x>" to support easy delegation to

59
Antoine Pitroue0e27352011-12-15 14:31:28 +010060- Fix OSError.__init__ and OSError.__new__ so that each of them can be
61 overriden and take additional arguments (followup to issue #12555).
62
Antoine Pitrou2e872082011-12-15 14:15:31 +010063- Fix the fix for issue #12149: it was incorrect, although it had the side

80
Antoine Pitrouf0effe62011-11-26 01:11:02 +010081- Issue #11849: Ensure that free()d memory arenas are really released

108
Antoine Pitrou5418ee02011-11-15 01:42:21 +0100109- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder
110 already accepts them).
111
Antoine Pitrou9a812cb2011-11-15 00:00:12 +0100112- Issue #13389: Full garbage collection passes now clear the freelists for
113 list and dict objects. They already cleared other freelists in the
114 interpreter.

118 order to update to the current time. Also added keyword argument
119 handling to os.utimensat in order to remove the need for explicit None.
Brian Curtin52fbea12011-11-06 13:41:17 -0600120

Ned Deily657b2de2011-06-28 19:51:30 -07001135- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1136 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1137 interpreter process. This could cause failures in non-Distutils subprocesses
1138 and was unreliable since tests or user programs could modify the interpreter
1139 environment after Distutils set it. Instead, have Distutils set the the
1140 deployment target only in the environment of each build subprocess. It is
1141 still possible to globally override the default by setting
1142 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1143 greater or equal to the default value, the value with which the interpreter
Ned Deily044369f2011-06-28 20:08:34 -07001144 was built. Also, implement the same handling in packaging.

1943
Nadeem Vawda3c01d162011-08-01 23:48:26 +02001944- Issue #11651: Improve the Makefile test targets to run more of the test suite
1945 more quickly. The --multiprocess option is now enabled by default, reducing
1946 the amount of time needed to run the tests. "make test" and "make quicktest"
1947 now include some resource-intensive tests, but no longer run the test suite
1948 twice to check for bugs in .pyc generation. Tools/scripts/run_test.py provides
Éric Araujo4f996442011-10-19 06:02:24 +02001949 an easy platform-independent way to run test suite with sensible defaults.

2249 files in binary mode, using the email package's binary support to parse
2250 arbitrary email messages. StringIO and text file input is deprecated,
2251 and string input fails early if non-ASCII characters are used, where
Éric Araujoac4e58e2011-01-29 20:32:11 +00002252 previously it would fail when the email was processed in a later step.

2280 keyword-only argument. The preceding positional argument was deprecated,
2281 so it made no sense to add filter as a positional argument.

Antoine Pitrou305bc9e2011-01-20 21:07:24 +00002296 filenames, at bootstrap, if the codec registry is not ready yet. It is still
2297 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
2298 for all file entries in the ZIP file.

2308- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
2309 encoding. This is the preferred encoding of PEP 3333 and the base encoding
2310 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00002311
2312- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00002313 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00002314 that for incoming headers which makes this behaviour now consistent in
2315 both incoming and outgoing direction.

Georg Brandl255abdd2011-01-16 14:17:26 +00002412 continuation line in the formatted value has no leading white space and looks
2413 like a header. Since Generator uses Header to format all headers, this check
2414 is made for all headers in any serialized message at serialization time. This
2415 provides protection against header injection attacks.

Victor Stinnerf933e1a2010-10-20 22:58:25 +00003073 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00003074 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00003075 encoding and to encode command line arguments on this OS.

3078 filenames encoded to the filesystem encoding with the surrogateescape error

3470 with a non-empty format string. This is an effort to future-proof user
3471 code. If a derived class does not currently implement __format__ but later
3472 adds its own __format__, it would most likely break user code that had
3473 supplied a format string. This will be changed to a DeprecationWaring in
3474 Python 3.3 and it will be an error in Python 3.4.

3478 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Georg Brandl27a28582010-10-10 09:49:21 +00003491- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
3492 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
3493 Also, the "backslashreplace" error handler now joins surrogate pairs into a
3494 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00003529- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003530 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00003531 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00003532 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00003557 retry the select() loop instead of bailing out. This is because select() can
3558 incorrectly report a socket as ready for reading (for example, if it received
3559 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00003639- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00003640 it possible for the user to create self-referencing ordered dictionaries which
3641 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00003642 approach of using weakref proxies so that reference cycles never get created
3643 in the first place.

Victor Stinnercb043522010-09-10 23:49:04 +00003645- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Georg Brandl27a28582010-10-10 09:49:21 +00003649- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
3650 environment variable to set the filesystem encoding at Python startup.
3651 sys.setfilesystemencoding() creates inconsistencies because it is unable to
3652 reencode all filenames in all objects.

Georg Brandl27a28582010-10-10 09:49:21 +00003658- The pprint module now supports printing OrderedDicts in their given order

3663
Georg Brandl27a28582010-10-10 09:49:21 +00003664- Issue #9707: Rewritten reference implementation of threading.local which is
3665 friendlier towards reference cycles. This change is not normally visible
3666 since an optimized C implementation (_thread._local) is used instead.
Antoine Pitrou783eea72010-09-07 22:06:17 +00003667
Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00003668- Issue #6394: os.getppid() is now supported on Windows. Note that it will
3669 still return the id of the parent process after it has exited. This process
3670 id may even have been reused by another unrelated process.
3671
Georg Brandl27a28582010-10-10 09:49:21 +00003672- Issue #9792: In case of connection failure, socket.create_connection() would
3673 swallow the exception and raise a new one, making it impossible to fetch the
3674 original errno, or to filter timeout errors. Now the original error is
3675 re-raised.

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00003681- Updates to the random module:
3682
Georg Brandl27a28582010-10-10 09:49:21 +00003683 * Document which parts of the module are guaranteed to stay the same across
3684 versions and which parts are subject to change.

Georg Brandl27a28582010-10-10 09:49:21 +00003686 * Update the seed() method to use all of the bits in a string instead of just
3687 the hash value. This makes better use of the seed value and assures the
3688 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00003689
Georg Brandl27a28582010-10-10 09:49:21 +00003690 * Improved the random()-->integer algorithm used in choice(), shuffle(),
3691 sample(), randrange(), and randint(). Formerly, it used int(n*random())
3692 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00003693
3694 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00003713- hashlib has two new constant attributes: algorithms_guaranteed and

3715 guaranteed to exist in all Python implementations and the names of hash
3716 algorithms available in the current process.

3845 return characters from the full Unicode range, even on narrow unicode builds
3846 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
3847 in Python is that unicodedata.numeric() now returns the correct value for
3848 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00003874- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
3875 use PyUnicode_FromFormatV() to format the warning message.

3883 repr().
Mark Dickinson388122d2010-08-04 20:56:28 +00003884
Georg Brandl649971e2010-09-05 17:06:50 +00003885- Issue #9416: Fix some issues with complex formatting where the output with no
3886 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00003887
3888 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3889 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

4218Core and Builtins
4219-----------------
4220
Victor Stinner8182b712010-07-28 00:40:58 +00004221- Issue #8991: convertbuffer() rejects discontigious buffers.
4222
Antoine Pitrou1ac745b2010-07-11 12:12:00 +00004223- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
4224 compiler.
4225
Benjamin Petersonccabcd42010-07-07 20:54:01 +00004226- Issue #8413: structsequence now subclasses tuple.
4227
Ezio Melotti57221d02010-07-01 07:32:02 +00004228- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00004229 start byte and the continuation byte(s) are now considered invalid, instead of
4230 the number of bytes specified by the start byte. E.g.:
4231 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
4232 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
4233 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
4234 returned a single u'\ufffd'.
Ezio Melotti57221d02010-07-01 07:32:02 +00004235
Georg Brandl62069d32010-07-31 08:56:11 +00004236- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
4237 rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
Mark Dickinson50b79a82010-06-30 11:13:36 +00004238
Benjamin Peterson88968ad2010-06-25 19:30:21 +00004239- Be more specific in error messages about positional arguments.
4240
Victor Stinner4aae1eb2010-06-24 22:08:25 +00004241- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
4242 objects, as described in the documentation.
4243
Victor Stinner0fe25a42010-06-17 23:08:50 +00004244- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Georg Brandl62069d32010-07-31 08:56:11 +00004245 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
Victor Stinner2cd12522010-06-17 23:17:37 +00004246 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +00004247
Georg Brandl62069d32010-07-31 08:56:11 +00004248- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
4249 dealing with unary minus applied to a constant. The removed code was mutating
4250 the ST, causing a second compilation to fail.
Mark Dickinsond35a32e2010-06-17 12:33:22 +00004251
Victor Stinner554f3f02010-06-16 23:33:54 +00004252- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
Georg Brandl62069d32010-07-31 08:56:11 +00004253 mode raises unicode errors. The encoder only supports "strict" and "replace"
Victor Stinner554f3f02010-06-16 23:33:54 +00004254 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00004255 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00004256
Victor Stinner25e8ec42010-06-25 00:02:38 +00004257- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
4258 "w*" format instead. Add tests for "w*" format.
4259
Victor Stinner06e49dd2010-06-13 18:21:50 +00004260- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00004261 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00004262 string formats.
4263
Georg Brandl62069d32010-07-31 08:56:11 +00004264- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00004265 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
4266 location of the raised exception.
4267
Victor Stinner313a1202010-06-11 23:56:51 +00004268- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
4269 filenames and enable os.fsencode().
4270
Benjamin Peterson285a6892010-06-22 19:21:52 +00004271- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
4272
Georg Brandl62069d32010-07-31 08:56:11 +00004273- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
4274 interpreter with characters outside the Basic Multilingual Plane (higher than
4275 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00004276
Georg Brandl62069d32010-07-31 08:56:11 +00004277- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
4278 TypeError instead of giving a DeprecationWarning when a float is parsed using
4279 the 'L' code (for long long). (All other integer codes already raise
4280 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00004281
Victor Stinner600d3be2010-06-10 12:00:55 +00004282- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
4283 enable shortcuts for upper case encoding name. Add also a shortcut for
4284 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
4285
Georg Brandl62069d32010-07-31 08:56:11 +00004286- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
4287 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004288
4289- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00004290 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00004291 like bytearray.
4292
Georg Brandl62069d32010-07-31 08:56:11 +00004293- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00004294 used anymore and it was never documented.
4295
Georg Brandl62069d32010-07-31 08:56:11 +00004296- In str.format(), raise a ValueError when indexes to arguments are too large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +00004297
Georg Brandl62069d32010-07-31 08:56:11 +00004298- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
4299 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00004300
Georg Brandl62069d32010-07-31 08:56:11 +00004301- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
4302 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
4303 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
4304 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00004305
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004306- Issue #8748: Fix two issues with comparisons between complex and integer
4307 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00004308 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
4309 (2) The comparison raised an OverflowError for large integers, leading to
4310 unpredictable exceptions when combining integers and complex objects in sets
4311 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00004312
Victor Stinner7d79b8b2010-05-19 20:40:50 +00004313- Issue #8766: Initialize _warnings module before importing the first module.
4314 Fix a crash if an empty directory called "encodings" exists in sys.path.
4315
Victor Stinner9ca9c252010-05-19 16:53:30 +00004316- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00004317 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00004318 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00004319
Georg Brandl62069d32010-07-31 08:56:11 +00004320- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
4321 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00004322
Victor Stinnerae6265f2010-05-15 16:27:27 +00004323- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
4324 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00004325 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00004326 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00004327
Victor Stinner59e62db2010-05-15 13:14:32 +00004328- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00004329 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00004330
Victor Stinnerb744ba12010-05-15 12:27:16 +00004331- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00004332 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00004333 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
4334
Victor Stinner0964ee12010-04-30 16:48:45 +00004335- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00004336 PyUnicode_FromString() to support surrogates in the filename and use the right
4337 encoding.
Victor Stinner0964ee12010-04-30 16:48:45 +00004338
Georg Brandl8569e582010-05-19 20:57:08 +00004339- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
4340
Georg Brandl62069d32010-07-31 08:56:11 +00004341- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00004342
Benjamin Petersonfb886362010-04-24 18:21:17 +00004343- Issue #8419: Prevent the dict constructor from accepting non-string keyword
4344 arguments.
4345
Victor Stinner14284c22010-04-23 12:02:30 +00004346- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00004347 indirectly Python signal handlers anymore because mywrite() ignores exceptions
4348 (KeyboardInterrupt).
Victor Stinner14284c22010-04-23 12:02:30 +00004349
Victor Stinner31be90b2010-04-22 19:38:16 +00004350- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
Georg Brandl62069d32010-07-31 08:56:11 +00004351 unicode string (eg. backslashreplace).
Victor Stinner31be90b2010-04-22 19:38:16 +00004352
Georg Brandl62069d32010-07-31 08:56:11 +00004353- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
4354 anymore, you have to convert your bytearray filenames to bytes.
Victor Stinnerdcb24032010-04-22 12:08:36 +00004355
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +00004356- Issue #7332: Remove the 16KB stack-based buffer in
Georg Brandl62069d32010-07-31 08:56:11 +00004357 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
4358 compared to the dynamic memory allocation fallback. Patch by Charles-François
4359 Natali.

4437 crash in many places because of the PyByteArray_AS_STRING() macro returning
4438 NULL. The macro now returns a statically allocated empty string instead.

Antoine Pitroub7fbcd32010-01-16 18:37:38 +00004440- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
Georg Brandl62069d32010-07-31 08:56:11 +00004441 where the right hand operand is a set of constants, by turning the set into a
4442 frozenset and pre-building it as a constant. The comparison operation is made
4443 against the constant instead of building a new set each time it is executed (a
4444 similar optimization already existed which turned a list of constants into a
4445 pre-built tuple). Patch and additional tests by Dave Malcolm.

4452 including: (1) a serious 'wrong output' bug that could occur for long (> 40
4453 digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
4454 parsing certain long numeric strings corresponding to subnormal values, (3) a

4472 least on IEEE 754 platforms), and in particular does not depend on the
4473 internal representation of an int.

4749 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00004750 applications that use a lot of regular expressions and limits the impact of
4751 the performance hit anytime the cache is exceeded.

R. David Murrayb2416e52010-04-12 16:58:02 +00005131- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00005132 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00005151- Issue #8257: The Decimal construct now accepts a float instance directly,
5152 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00005153
5154 >>> Decimal(1.1)
5155 Decimal('1.100000000000000088817841970012523233890533447265625')

Georg Brandl62069d32010-07-31 08:56:11 +00005160- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5161 InvalidOperation instead of returning False. (Comparisons involving a quiet
5162 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5163 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00005164
Georg Brandl62069d32010-07-31 08:56:11 +00005165- Issue #2531: Comparison operations between floats and Decimal instances now
5166 return a result based on the numeric values of the operands; previously they
5167 returned an arbitrary result based on the relative ordering of id(float) and
5168 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
5169 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00005170
Raymond Hettinger9c01e442010-04-03 10:32:58 +00005171- Added a subtract() method to collections.Counter().
5172
Barry Warsawd5f9bf52010-03-31 21:36:22 +00005173- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00005174 argument `-` which tells it to read files to compile from stdin. Each line is
5175 read on demand and the named file is compiled immediately. (Original patch by
5176 Piotr Ożarowski).

Florent Xicluna806d8cf2010-03-30 19:34:18 +00005178- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and

Georg Brandl62069d32010-07-31 08:56:11 +00005182- Comparisons using one of <, <=, >, >= between a complex instance and a
5183 Fractions instance now raise TypeError instead of returning True/False. This
5184 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5185 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00005228- The internals of the subprocess module on POSIX systems have been replaced by
5229 an extension module (_posixsubprocess) so that the fork()+exec() can be done
5230 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00005231
Georg Brandl62069d32010-07-31 08:56:11 +00005232- subprocess.Popen now has restore_signals and start_new_session features. The
5233 default of restore_signals=True is a new behavior compared to earlier Python
5234 versions. This means that signals such as SIGPIPE are not ignored by default
5235 in subprocesses launched by Python (Issue #1652).

5322 position when calling `truncate()`. It would previously change the file
5323 position to the given argument, which goes against the tradition of

5328 archive. The new implementation is significantly faster and can be wrapped in
5329 a :class:`io.BufferedReader` object for more speedups. It also solves an
5330 issue where interleaved calls to `read()` and `readline()` give wrong results.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00005728- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00005729 compared to other unix systems. In particular, os.getgroups() does not reflect
5730 any changes made using os.setgroups() but basicly always returns the same
5731 information as the id command. os.getgroups() can now return more than 16
5732 groups on MacOSX.

6088 threads could return successfully while some Thread objects were still
6089 referenced. This also introduces a new private function:

6097
R. David Murray0bc11ae2009-10-18 22:18:17 +00006098- Issue #7058: Added save/restore for things like sys.argv and cwd to
Georg Brandl62069d32010-07-31 08:56:11 +00006099 runtest_inner in regrtest, with warnings if the called test modifies them, and

6377Core and Builtins
6378-----------------
6379
Mark Dickinson865e01a2009-05-07 16:37:01 +00006380- Issue #5914: Add new C API function PyOS_string_to_double, and
6381 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
6382
Eric Smith741191f2009-05-06 13:08:15 +00006383- Issue #3382: float.__format__, complex.__format__, and %-formatting
6384 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
6385 affects nan -> NAN and inf -> INF.
6386
Mark Hammond5a607a32009-05-06 08:04:54 +00006387- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
6388 in all operations, including splitdrive, split, etc. splitunc() now issues
6389 a PendingDeprecation warning.
6390
Eric Smith63376222009-05-05 14:04:18 +00006391- Issue #5920: For float.__format__, change the behavior with the
6392 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
6393 to be like 'g' but with at least one decimal point and with a
6394 default precision of 12. Previously, the behavior the same but with
6395 a default precision of 6. This more closely matches str(), and
6396 reduces surprises when adding alignment flags to the empty
6397 presentation type. This also affects the new complex.__format__ in
6398 the same way.
6399
Martin v. Löwis011e8422009-05-05 04:43:17 +00006400- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
6401
R. David Murrayb18500d2009-05-04 22:59:07 +00006402- Issue #5890: in subclasses of 'property' the __doc__ attribute was
6403 shadowed by classtype's, even if it was None. property now
6404 inserts the __doc__ into the subclass instance __dict__.
6405
Antoine Pitrou244651a2009-05-04 18:56:13 +00006406- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
6407 sequences. Patch by Nick Barnes and Victor Stinner.
6408
Martin v. Löwise0a2b722009-05-10 08:08:56 +00006409- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00006410
Benjamin Petersond2e0c792009-05-01 20:40:59 +00006411- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
6412 received a new method, detach(). detach() disconnects the underlying stream
6413 from the buffer or text IO and returns it.
6414
Mark Dickinson33841c32009-05-01 15:37:04 +00006415- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
6416 floats with absolute value over 1e50. Also remove length
6417 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
6418 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00006419
Eric Smith741191f2009-05-06 13:08:15 +00006420- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00006421 format(complex(1, 2./3), '.5') now produces a sensible result.
6422
Mark Dickinsond3ca5572009-04-29 18:47:07 +00006423- Issue #5864: Fix empty format code formatting for floats so that it
6424 never gives more than the requested number of significant digits.
6425
Eric Smith6dc46f52009-04-27 20:39:49 +00006426- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
6427 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
6428
Eric Smithcc32a112009-04-26 21:35:14 +00006429- Issue #5835: Deprecate PyOS_ascii_formatd.
6430
Martin v. Löwis71efeb72009-04-26 01:02:07 +00006431- Issue #4971: Fix titlecase for characters that are their own
6432 titlecase, but not their own uppercase.
6433
Benjamin Peterson193152c2009-04-25 01:08:45 +00006434- Issue #5283: Setting __class__ in __del__ caused a segfault.
6435
Mark Dickinsonad476da2009-04-23 19:14:16 +00006436- Issue #5816: complex(repr(z)) now recovers z exactly, even when
6437 z involves nans, infs or negative zeros.
6438
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00006439- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00006440
Mark Dickinsone6a076d2009-04-18 11:48:33 +00006441- Issue #1869 (and many duplicates): make round(x, n) correctly
6442 rounded for a float x, by using the decimal <-> binary conversions
6443 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
6444 consistently agrees with format(x, '.2f').
6445
Benjamin Petersonae937c02009-04-18 20:54:08 +00006446- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
6447 some builtin types.
6448
Eric Smith0923d1d2009-04-16 20:16:10 +00006449- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
6450
Eric Smith35e84722009-04-16 20:21:28 +00006451- Issue #5515: str.format() type 'n' combined with commas and leading
6452 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00006453
6454- Implement PEP 378, Format Specifier for Thousands Separator, for
6455 floats.
6456
Mark Dickinson3370cce2009-04-17 22:40:53 +00006457- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006458 1e11, not 1e12. This avoids printing 13 significant digits in
6459 situations where only 12 of them are correct. Example problem
6460 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
6461 long time.)
6462
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006463- Issue #1580: On most platforms, use a 'short' float repr: for a
6464 finite float x, repr(x) now outputs a string based on the shortest
6465 sequence of decimal digits that rounds to x. Previous behaviour was
6466 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00006467 Another minor difference is that the new repr switches to
6468 exponential notation at 1e16 instead of the previous 1e17; this
6469 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006470
6471 There's a new sys attribute sys.float_repr_style, which takes
6472 the value 'short' to indicate that we're using short float repr,
6473 and 'legacy' if the short float repr isn't available for one
6474 reason or another.
6475
6476 The float repr change involves incorporating David Gay's 'perfect
6477 rounding' code into the Python core (it's in Python/dtoa.c). As a
6478 secondary consequence, all string-to-float and float-to-string
6479 conversions (including all float formatting operations) will be
6480 correctly rounded on these platforms.
6481
Georg Brandl5f90d792010-08-01 22:31:05 +00006482 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00006483 this change does not apply.
6484
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00006485- Issue #5759: float() didn't call __float__ on str subclasses.
6486
Georg Brandlabc38772009-04-12 15:51:51 +00006487- The string.maketrans() function is deprecated; there is a new static method
6488 maketrans() on the bytes and bytearray classes. This removes confusion about
6489 the types string.maketrans() is supposed to work with, and mirrors the
6490 methods available on the str class.
6491
R. David Murraydc6da8a2009-04-09 22:16:43 +00006492- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
6493 its clarity and its speed.
6494
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006495- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00006496 to avoid compiler warnings.
6497
Walter Dörwald8dc33d52009-05-06 14:41:26 +00006498- Issue #3739: The unicode-internal encoder now reports the number of characters
6499 consumed like any other encoder (instead of the number of bytes).

6639 byte, and the 'C' code only accepts a unicode character.
6640
Georg Brandl406b3d82009-04-11 21:24:37 +00006641- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
6642 when hitting the recursion limit under certain circumstances.
6643
Brett Cannon0759dd62009-04-01 18:13:07 +00006644- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
6645
Georg Brandlab6f2f62009-03-31 04:16:10 +00006646- Fix a segfault when running test_exceptions with coverage, caused by
6647 insufficient checks in accessors of Exception.__context__.
6648
Guido van Rossum0ad59d42009-03-30 22:01:35 +00006649- Issue #5604: non-ASCII characters in module name passed to
6650 imp.find_module() were converted to UTF-8 while the path is
6651 converted to the default filesystem encoding, causing nonsense.
6652
Benjamin Peterson09832742009-03-26 17:15:46 +00006653- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00006655- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
6656 the end sys.path, for compatibility with the system install of Python.
6657
Antoine Pitrou3a652b12009-03-23 18:52:06 +00006658- Issue #4688: Add a heuristic so that tuples and dicts containing only
6659 untrackable objects are not tracked by the garbage collector. This can
6660 reduce the size of collections and therefore the garbage collection overhead
6661 on long-running programs, depending on their particular use of datatypes.
6662
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00006663- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
6664 improve its performance. Long divisions and remainder operations
6665 are now between 50% and 150% faster.
6666
Mark Dickinsonbd792642009-03-18 20:06:12 +00006667- Issue #4258: Make it possible to use base 2**30 instead of base
6668 2**15 for the internal representation of integers, for performance
6669 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
6670 --enable-big-digits option to configure, which overrides the
6671 default. Add sys.int_info structseq to provide information about
6672 the internal format.
6673
Mark Dickinson081dfee2009-03-18 14:47:41 +00006674- Issue #4474: PyUnicode_FromWideChar now converts characters outside
6675 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
6676 and sizeof(Py_UNICODE) == 2.
6677
Eric Smith8ec90442009-03-14 12:29:34 +00006678- Issue #5237: Allow auto-numbered fields in str.format(). For
6679 example: '{} {}'.format(1, 2) == '1 2'.
6680
Antoine Pitrou652e7072009-03-13 19:25:20 +00006681- Issue #5392: when a very low recursion limit was set, the interpreter would
6682 abort with a fatal error after the recursion limit was hit twice.
6683
Matthias Klose042f1332009-04-04 14:32:42 +00006684- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

6730
Lars Gustäbel42e00912009-03-22 20:34:29 +00006731- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
6732 forever on incomplete input. That caused tarfile.open() to hang when used
6733 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
6734 partial bzip2 compressed data.

6773 used when using str.format() with str, int, and float arguments.
6774
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00006775- Issue #5249: time.strftime returned malformed string when format string
6776 contained non ascii character on windows.
6777
Benjamin Petersonf5b52242009-03-02 23:31:26 +00006778- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
6779 source has already been decoded into str.
6780
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00006781- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
6782 rotating the object pointer by 4 bits to the right.
6783
Mark Dickinson87ec0852009-02-09 17:15:59 +00006784- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
6785 it now forces its argument to double before testing for infinity.
6786
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00006787- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
6788 returns a non-number type.
6789
Benjamin Peterson87618552009-02-08 15:00:52 +00006790- Issue #5182: Removed memoryview.__str__.
6791
Mark Dickinsonc008a172009-02-01 13:59:22 +00006792- Issue #1717: Removed builtin cmp() function, dropped tp_compare
6793 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00006794 the type definition cmpfunc. The tp_compare slot has been renamed
6795 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00006796
Georg Brandl1cdd83c2009-04-05 20:24:29 +00006797- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00006798 were suppressing all exceptions. These include list() and bytearray().
6799
Mark Dickinson1124e712009-01-28 21:25:58 +00006800- Issue #4707: round(x, n) now returns an integer if x is an integer.
6801 Previously it returned a float.
6802
Antoine Pitroub52ec782009-01-25 16:34:23 +00006803- Issue #4753: By enabling a configure option named '--with-computed-gotos'
6804 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
6805 evaluation loop is compiled with a new dispatch mechanism which gives
6806 speedups of up to 20%, depending on the system, on various benchmarks.
6807
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00006808- Issue #4874: Most builtin decoders now reject unicode input.

6816 optional module state data.
6817
Mark Dickinson8055afd2009-01-17 10:04:45 +00006818- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006819 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00006820
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00006821- Issue #4935: The overflow checking code in the expandtabs() method common
6822 to str, bytes and bytearray could be optimized away by the compiler, letting
6823 the interpreter segfault instead of raising an error.
6824
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00006825- Issue #3720: Fix a crash when an iterator modifies its class and removes its
6826 __next__ method.
6827
Mark Dickinsone5e298f2009-01-12 20:49:19 +00006828- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
6829 function no longer attempt to call the __long__ slot to convert an object
6830 to an integer. Only the __int__ and __trunc__ slots are examined.

6835
Antoine Pitrouab868312009-01-10 15:40:25 +00006836- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
6837 common cases are optimized thanks to a dedicated fast path and a moderate
6838 amount of loop unrolling.
6839
Antoine Pitrou14b78f52009-01-09 22:27:08 +00006840- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
6841 collecting the oldest generation) so that allocating lots of objects without
6842 destroying them does not show quadratic performance. Based on a proposal by
6843 Martin von Löwis at
6844 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
6845
Vinay Sajip6268cbc2009-01-21 00:19:28 +00006846- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00006847 having been closed (for instance, a read() call could return some
6848 previously buffered data). Patch by Dmitry Vasiliev.
6849
Antoine Pitrou05608432009-01-09 18:53:14 +00006850- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
6851 flag to work properly. Furthermore, when specifying -u, the text stdout
6852 and stderr streams have line-by-line buffering enabled (the default being
6853 to buffer arbitrary chunks of data).
6854
Raymond Hettinger35631532009-01-09 03:58:09 +00006855- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
6856 instead of ints (reducing its size from 4 to 8 times thereby reducing
6857 Python's overall memory).
6858
Antoine Pitroud35cbf62009-01-06 19:02:24 +00006859- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
6860 an existing .py counterpart, override the co_filename attributes of all
6861 code objects if the original filename is obsolete (which can happen if the
6862 file has been renamed, moved, or if it is accessed through different paths).
6863 Patch by Ziga Seilnacht and Jean-Paul Calderone.
6864
Antoine Pitrouc3b39242009-01-03 16:59:18 +00006865- Issue #4580: Fix slicing of memoryviews when the item size is greater than
6866 one byte. Also fixes the meaning of len() so that it returns the number of
6867 items, rather than the size in bytes.
6868
Martin v. Löwis5c88d812009-01-02 20:47:48 +00006869- Issue #4075: Use OutputDebugStringW in Py_FatalError.
6870
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00006871- Issue #4747: When the terminal does not use utf-8, executing a script with
6872 non-ascii characters in its name could fail with a "SyntaxError: None" error.
6873
Georg Brandl65ce6ad2010-09-05 17:32:31 +00006874- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
6875 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00006876
Antoine Pitrou7ddda782009-01-01 15:35:33 +00006877- Issue #3680: Reference cycles created through a dict, set or deque iterator
6878 did not get collected.
6879
Nick Coghlanf1f2f682008-12-30 07:29:12 +00006880- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
6881 where the tp_hash and tp_dict slots are both NULL.
6882
Georg Brandlccc47b62008-12-28 11:44:14 +00006883- Issue #4759: None is now allowed as the first argument of
6884 bytearray.translate(). It was always allowed for bytes.translate().
6885
Skip Montanaro80072cb2008-12-23 03:51:14 +00006886- Added test case to ensure attempts to read from a file opened for writing
6887 fail.
6888
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00006889- Issue #3106: Speedup some comparisons (str/str and int/int).

6892 comprehensions. Original patch for list comprehensions by Neal Norwitz.
6893
Antoine Pitrou621601a2008-12-17 23:18:19 +00006894- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
6895 print elapsed times, not only when some objects are uncollectable /
6896 unreachable. Original patch by Neil Schemenauer.
6897
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00006898- Issue #3439: Add a bit_length method to int.
6899
Mark Dickinsonda2706b2008-12-11 18:03:03 +00006900- Issue #2173: When getting device encoding, check that return value of
6901 nl_langinfo is not the empty string. This was causing silent build
6902 failures on OS X.
6903
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00006904- Issue #4597: Fixed several opcodes that weren't always propagating
6905 exceptions.
6906
6907- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00006908 context manager returns a value that cannot be converted to a bool.
6909
Mark Dickinsonfd24b322008-12-06 15:33:31 +00006910- Issue #4445: Replace "sizeof(PyBytesObject)" with
6911 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
6912 bytes instances. On a typical machine this saves 3 bytes of memory
6913 (on average) per allocation of a bytes instance.
6914
Christian Heimesa872de52008-12-05 08:26:55 +00006915- Issue #4533: File read operation was dreadfully slow due to a slowly
6916 growing read buffer. Fixed by using the same growth rate algorithm as
6917 Python 2.x.
6918
Antoine Pitrou5504e892008-12-06 21:27:53 +00006919- Issue #4509: Various issues surrounding resize of bytearray objects to

7256
Antoine Pitrou08838b62009-01-21 00:55:13 +00007257- Issue #5008: When a file is opened in append mode with the new IO library,
7258 do an explicit seek to the end of file (so that e.g. tell() returns the
7259 file size rather than 0). This is consistent with the behaviour of the
7260 traditional 2.x file object.

7290 appropriately when it is being used via socket.makefile() objects
7291 rather than delaying the close by waiting for garbage collection to do it.
7292
Raymond Hettingerb8baf632009-01-14 02:20:07 +00007293- Issue #1696199: Add collections.Counter() for rapid and convenient

Guilherme Polo2a998fa2009-06-21 17:40:07 +00007542- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7543 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
7544 the same behaviour as test_ttkguionly (and now also test_tk) which is to
7545 skip the tests if DISPLAY is defined but can't be used.
7546
R. David Murraya21e4ca2009-03-31 23:16:50 +00007547- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00007548 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00007549 from test support, which does the conversion.
