527
528- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
529 and later systems as is currently done for Python 3.x installers.
530 For 2.7.7 only, we will provide three installers:
531 the legacy deprecated 10.3+ 32-bit-only format;
532 the newer 10.5+ 32-bit-only format;
533 and the unchanged 10.6+ 64-/32-bit format.
534 Although binary installers will no longer be available from
535 python.org as of 2.7.8, it will still be possible to build from
536 source on 10.3.9 and 10.4 systems if necessary.
537 See Mac/BuildScript/README.txt for more information.

1916 32-bit-only installer Pythons on systems with Xcode 4 (currently
1917 OS X 10.8, 10.7, and optionally 10.6).
1918 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1919 * Since Xcode 4 removes ppc support, extension module builds now
1920 check for ppc compiler support and by default remove ppc and
1921 ppc64 archs when they are not available.
1922 * Extension module builds now revert to using system installed
1923 headers and libs (/usr and /System/Library) if the SDK used
1924 to build the interpreter is not installed or has moved.
1925 * Try to avoid building extension modules with deprecated
1926 and problematic Apple llvm-gcc compiler. If original compiler
1927 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002351- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002352 has left two versions of customize_compiler, the original in
2353 distutils.sysconfig and another copy in distutils.ccompiler, with some
2354 parts of distutils calling one and others using the other.
2355 Complete the revert back to only having one in distutils.sysconfig as
2356 is the case in 3.x.
2357
Ned Deily0d0ea482012-02-10 12:59:06 +01002358- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2359 Distutils-based packages with C extension modules may fail because
2360 Apple has removed gcc-4.2, the version used to build python.org
2361 64-bit/32-bit Pythons. If the user does not explicitly override
2362 the default C compiler by setting the CC environment variable,
2363 Distutils will now attempt to compile extension modules with clang
2364 if gcc-4.2 is required but not found. Also as a convenience, if
2365 the user does explicitly set CC, substitute its value as the default
2366 compiler in the Distutils LDSHARED configuration variable for OS X.
2367 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2368 SDK, neither of which are available in Xcode 4. This change does not
2369 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002619- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2620 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2621 interpreter process. This could cause failures in non-Distutils subprocesses
2622 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002623 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002624 deployment target only in the environment of each build subprocess. It is
2625 still possible to globally override the default by setting
2626 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2627 greater or equal to the default value, the value with which the interpreter
2628 was built.

2658 the ticker doesn't have to wind down to zero from the old starting point
2659 before the new interval takes effect. And if the user increases the
2660 interval, it makes sure the new limit takes effect right away rather have an
2661 early task switch before recognizing the new interval.

4102-----------------
4103
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004104- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4105 start byte and the continuation byte(s) are now considered invalid, instead
4106 of the number of bytes specified by the start byte.
4107 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4108 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4109 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4110 Previous versions returned a single u'\ufffd'.
4111
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004112- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00004113 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
4114 arises from the "Overriding __eq__ blocks inheritance ..." warning
4115 when turned into an exception: in this case the exception simply
4116 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004117
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004118- Issue #8748: Fix two issues with comparisons between complex and integer
4119 objects. (1) The comparison could incorrectly return True in some cases
4120 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4121 (2) The comparison raised an OverflowError for large integers, leading
4122 to unpredictable exceptions when combining integers and complex objects
4123 in sets or dicts.
4124
Mark Dickinson81336372010-05-30 12:12:25 +00004125- Issue #5211: Implicit coercion for the complex type is now completely
4126 removed. (Coercion for arithmetic operations was already removed in 2.7
4127 alpha 4, but coercion for rich comparisons was accidentally left in.)
4128
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004129- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
4130 and error handler, instead of writing to the C stderr file in utf-8
4131
Georg Brandlfee0f442010-05-22 21:26:21 +00004132- Issue #7902: When using explicit relative import syntax, don't try implicit
4133 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00004134

4136 from another thread. Patch by Daniel Stutzbach.

4506 with a non-empty format string. This is an effort to future-proof user
4507 code. If a derived class does not currently implement __format__ but later
4508 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004509 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004510 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004570- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004571 argument `-` which tells it to read files to compile from stdin. Each line is
4572 read on demand and the named file is compiled immediately. (Original patch by

4960 strings,
4961 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Antoine Pitroud840e512010-02-04 20:20:18 +00004995- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004996 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005002- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005003 file position when calling `truncate()`. It would previously change the file
5004 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005005 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5006

5008 class used to represent files stored inside an archive. The new
5009 implementation is significantly faster and can be wrapped in a
5010 ``io.BufferedReader`` object for more speedups. It also solves an issue
5011 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00005022- Issue #7748: Since unicode values are supported for some metadata options in

5024 encoded string for them. This ensures that the upload and register commands
5025 send the correct values to PyPI without any error.

5101
Georg Brandlba83f822010-03-14 09:50:54 +00005102- The ``__complex__()`` method is now looked up on the class of instances to
5103 make it consistent with other special methods.

5107
Mark Dickinson1b34d252010-01-01 17:27:30 +00005108- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005109 DeprecationWarning when passed a float argument where an integer was expected.
5110 These functions and methods now raise TypeError instead. The majority of the
5111 effects of this change are in the extension modules, but some core functions
5112 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5113 and many unicode/str methods.

5127 of integers: the result of a/b is now correctly rounded for ints a and b (at
5128 least on IEEE 754 platforms), and in particular does not depend on the
5129 internal representation of a long.

5137
Georg Brandlba83f822010-03-14 09:50:54 +00005138 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005295- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5296 decimal string that's guaranteed to round back to x under correct rounding
5297 (with round-half-to-even rounding mode). Previously it gave a string based on
5298 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5299 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5300 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00005302- Issue #7117: On almost all platforms: float-to-string and string-to-float
5303 conversions within Python are now correctly rounded. Places these conversions
5304 occur include: str for floats and complex numbers; the float and complex
5305 constructors; old-style and new-style numeric formatting; serialization and
5306 deserialization of floats and complex numbers using marshal, pickle and json;
5307 parsing of float and imaginary literals in Python code; Decimal-to-float
5308 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005309
Georg Brandlba83f822010-03-14 09:50:54 +00005310 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5311 providing correctly-rounded strtod and dtoa C functions. This code is
5312 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5313 the C compiler. There may be a small number of platforms on which correct
5314 operation of this code cannot be guaranteed, so the code is not used: notably,
5315 this applies to platforms where the C double format is not IEEE 754 binary64,
5316 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5317 and Python's configure script is unable to determine how to change the FPU
5318 precision. On these platforms conversions use the platform strtod and dtoa,
5319 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005321- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5322 uses the correctly-rounded string <-> float conversions described above (when
5323 available), and so produces correctly rounded results that will display nicely
5324 under the float repr. There are two related small changes: (1) round now
5325 accepts any class with an ``__index__()`` method for its second argument (but
5326 no longer accepts floats for the second argument), and (2) an excessively
5327 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5328 raises an exception.

6914 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6915 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00006970 leak-chasing test runs give sensible results. The previous method of reaping
6971 threads could return successfully while some Thread objects were still
6972 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00006973
Georg Brandlba83f822010-03-14 09:50:54 +00006974- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00006991 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007114- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7116 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7117 ``printf`` function, whereas PyString_FromFormat has an independent
7118 implementation and uses "%zd" on all platforms for size_t values.

7127 method is allowed to return either an int or a long, but the behaviour of
7128 float objects should not change to respect backward compatibility.
7129
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007130- Issue #3751: str.rpartition would perform a left-partition when called with
7131 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007135- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007136 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007137 was correctly parsed but parsing of subsequent arguments failed.
7138
Vinay Sajip35e3b032008-09-01 14:33:59 +00007139- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007140 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7141 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7142 when given a tuple of classes as second argument, were looking up
7143 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7144 type object.
7145
Neal Norwitz18aa3882008-08-24 05:04:52 +00007146- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007215 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7216 for catch_warnings() also led to an improvement in the raising of a
7217 DeprecationWarning related to warnings.warn_explicit().
7218

7245
Benjamin Peterson37346b22008-08-23 20:27:43 +00007246- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007283What's New in Python 2.6 beta 3?
7284================================
7285
Barry Warsaw07a4a382008-08-21 01:15:08 +00007286*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007287
7288Core and Builtins
7289-----------------
7290
Guido van Rossumf8402962008-08-20 15:01:50 +00007291- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7292 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7293 extensions do not automatically benefit from the class attribute
7294 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7295 to their tp_flags field if they care. This is a backwards
7296 compatibility feature; in 3.0, all types will use the cache by
7297 default.
7298
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007299- Keyword arguments can now follow starred arguments. (``f(a, *args,
7300 keyword=23)`` is now valid syntax.)
7301
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007302- ctypes function pointers that are COM methods have a boolean True
7303 value again.
7304
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007305- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7306 by denying s# to parse objects that have a releasebuffer procedure,
7307 and introducing s*.
7308
Georg Brandl1e13ea92008-08-11 09:07:59 +00007309- Issue #3537: Fix an assertion failure when an empty but presized dict
7310 object was stored in the freelist.
7311
Mark Dickinsonb6467572008-08-04 21:30:09 +00007312- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7313 ValueError consistently across platforms.
7314
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007315- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7316 (64bit Unix, for example), unichr() would truncate its argument and return
7317 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7318
Neal Norwitze7d8be82008-07-31 17:17:14 +00007319- Apply security patches from Apple.
7320
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007321- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7322 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7323
Antoine Pitrou92f82162008-07-25 22:22:08 +00007324- Issue #1819: function calls with several named parameters are now on
7325 average 35% faster (as measured by pybench).
7326
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007327- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7328 the python debugger steps into a class statement: the free variables (local
7329 variables defined in an outer scope) would be deleted from the outer scope.
7330
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007331- Issue #2620: Overflow checking when allocating or reallocating memory
7332 was not always being done properly in some python types and extension
7333 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7334 all been updated to perform better checks and places in the code that
7335 would previously leak memory on the error path when such an allocation
7336 failed have been fixed.

7339-------
7340
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007341- Issue #3612: Added some missing basic types in ctypes.wintypes.
7342
Benjamin Petersone977ad42008-08-20 01:42:01 +00007343- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7344 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7345
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007346- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7347 version reported by these tools does not necessarily follow the python
7348 version numbering scheme, so the module is less strict when parsing it.
7349
Nick Coghlanf70385a2008-08-18 12:42:46 +00007350- Issue #2235: Added Py3k warnings for types which will become unhashable
7351 under the stricter __hash__ inheritance rules in 3.0. Several types
7352 which did not meet the rules for hash invariants and were already
7353 unhashable in 3.0 have now been explicitly flagged as unhashable in
7354 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7355 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7356
Brett Cannon88f801d2008-08-18 00:46:22 +00007357- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7358 imported into the module but exposed as part of the module's API.
7359
Brett Cannon7b96f072008-08-18 00:41:11 +00007360- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7361
Brett Cannon46225e72008-08-18 00:36:52 +00007362- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

7365
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007366- Issue #3575: Incremental decoder's decode function now takes bytearray
7367 by using 's*' instead of 't#'.
7368
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007369- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007370 fails unicode conversion on 2nd parameter. (windows only)
7371
Georg Brandl222e2082010-08-01 22:27:39 +00007372- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007373 in a redirect.
7374
Brett Cannonabe423e2008-08-16 21:47:07 +00007375- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007376 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007377
Facundo Batistaeb90b782008-08-16 14:44:07 +00007378- Issue #2776: fixed small issue when handling an URL with double slash
7379 after a 302 response in the case of not going through a proxy.
7380
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007381- Issue #2676: in the email package, content-type parsing was hanging on
7382 pathological input because of quadratic or exponential behaviour of a
7383 regular expression.
7384
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007385- Issue #3476: binary buffered reading through the new "io" library is now
7386 thread-safe.
7387
Brett Cannonbf3157b2008-08-14 05:00:03 +00007388- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7389 since mimetools itself is deprecated. Because modules are cached, all
7390 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7391
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007392- Issue #3134: shutil referenced undefined WindowsError symbol.
7393
Robert Schuppenies14646332008-08-10 11:01:53 +00007394- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7395 menu entries were not deleted.
7396
Brett Cannon83e81842008-08-09 23:30:55 +00007397- Copied the implementation of reduce() to _functools.reduce() to have a
7398 version that did not raise a DeprecationWarning under -3.
7399
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007400- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7401 a MemoryError rather than silently stop the iteration.
7402
Guido van Rossum59ce9012008-08-09 14:55:34 +00007403- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7404 to _sre.compile() will now be rejected. This should not affect anybody
7405 since the re.compile() function never generates invalid re-bytecode.
7406
Skip Montanaroa032bf42008-08-08 22:52:51 +00007407- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7408 upon first access it can be automatically initialized from the csv file if
7409 it wasn't initialized during instantiation.

7483-----------------
7484
Georg Brandl3e483f62008-07-16 22:57:41 +00007485- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7486 its methods now allow for items objects that can be converted to
7487 an integer using operator.index().
7488
Mark Dickinson64b7e502008-07-16 09:40:03 +00007489- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7490 produced a ValueError instead of giving the correct float.
7491
Eric Smitha5fa5a22008-07-16 00:11:49 +00007492- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7493 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7494
Mark Dickinson7103aa42008-07-15 19:08:33 +00007495- Issue #3008: the float type has a new instance method 'float.hex'
7496 and a new class method 'float.fromhex' to convert floating-point
7497 numbers to and from hexadecimal strings, respectively.
7498
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007499- Issue #2235: __hash__ is once again inherited by default. To allow
7500 collections.Hashable to remain meaningful in the presence of the
7501 default hash implementation (object.__hash__), it is now possible
7502 to explicit block inheritance of hash by setting __hash__=None at
7503 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7504 level.
7505
Nick Coghlanb028f502008-07-13 14:52:36 +00007506- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7507 the parent module cannot be found while performing an absolute import.
7508 This means that an incorrectly defined __package__ attribute will
7509 now only prevent relative imports in that module rather than causing
7510 all imports from that module to fail.
7511
Nick Coghlan14ff9942008-07-08 14:21:42 +00007512- Issue #2517: Allow unicode messages in Exceptions again by correctly

7522 another thread's dictionary.
7523
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007524- Issue #3004: Minor change to slice.indices(): the start and stop
7525 arguments are now treated identically, making the behaviour easier
7526 to describe and understand. For example, slice(None, -10,
7527 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7528 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7529 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007531- Issue #3219: Calling a function with repeated keyword arguments,
7532 f(a=2, a=23), would not cause a syntax error. This was a regression
7533 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007571- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7572 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007573 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007574 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007590- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7976
Brett Cannonb61d8012008-05-11 23:39:04 +00007977- ``Lib/lib-old`` is now added to sys.path.
7978
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007979- On MacOS X it is now possible to install the framework in 64-bit
7980 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007981 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007982
7983 This is controlled by the configure argument ``--with-universal-archs``:
7984
7985 - ``--with-universal-archs=all``: install 4-way universal
7986
7987 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7988
7989 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7990
7991 This option should be used in combination with ``--enable-universalsdk=``.
7992
7993 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

8000- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00008001
8002- The PyString functions have been renamed to PyBytes. A batch of
8003 defines were added so that the linker still sees the original
8004 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008042- Issue #1631171: Re-implement the 'warnings' module in C (the
8043 original Python code has been kept as backup). This will allow for
8044 using the 'warning's machinery in such places as the parser where
8045 use of pure Python code is not possible. Both the ``showarning()``
8046 and ``formatwarning()`` gain an optional 'line' argument which is
8047 not called by default for backwards-compatibility reasons. Setting
8048 ``warnings.showwarning()`` to an implementation that lacks support
8049 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008074- The getpass module has been improved on Unix. It now uses /dev/tty
8075 by default and uses stderr instead of stdout. A GetPassWarning is
8076 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008091- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008092 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008112- Issue #2550: The approach used by client/server code for obtaining
8113 ports to listen on in network-oriented tests has been refined in an
8114 effort to facilitate running multiple instances of the entire
8115 regression test suite in parallel without issue.
8116 test_support.bind_port() has been fixed such that it will always
8117 return a unique port -- which wasn't always the case with the
8118 previous implementation, especially if socket options had been set
8119 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8120 new implementation of bind_port() will actually raise an exception
8121 if it is passed an AF_INET/SOCK_STREAM socket with either the
8122 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8123 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8124 the socket it's been passed. This currently only applies to
8125 Windows. This option prevents any other sockets from binding to the
8126 host/port we've bound to, thus removing the possibility of the
8127 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8128 when a second SOCK_STREAM socket binds and accepts to a host/port
8129 that's already been bound by another socket. The optional preferred
8130 port parameter to bind_port() has been removed. Under no
8131 circumstances should tests be hard coding ports!
8132
8133 test_support.find_unused_port() has also been introduced, which will
8134 pass a temporary socket object to bind_port() in order to obtain an
8135 unused port. The temporary socket object is then closed and
8136 deleted, and the port is returned. This method should only be used
8137 for obtaining an unused port in order to pass to an external program
8138 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8139 a parameter to a server-oriented class that doesn't give you direct
8140 access to the underlying socket used.
8141
8142 Finally, test_support.HOST has been introduced, which should be used
8143 for the host argument of any relevant socket calls (i.e. bind and
8144 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008145
8146 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008147 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008148 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8149 test_asynchat and test_socket_ssl.
8150
Georg Brandl3ee81df2008-05-17 18:14:43 +00008151 It is now possible for multiple instances of the regression test
8152 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008431- Added the future_builtins module, which contains hex() and oct().
8432 These are the PEP 3127 version of these functions, designed to be
8433 compatible with the hex() and oct() builtins from Python 3.0. They
8434 differ slightly in their output formats from the existing, unchanged
8435 Python 2.6 builtins. The expected usage of the future_builtins
8436 module is:
8437 from future_builtins import hex, oct
8438
Eric Smith7ef40bf2008-02-20 23:34:22 +00008439- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8440 exponents for exponents with absolute value < 100. Follows C99
8441 standard. This is a change on Windows, which would use 3 digits.
8442 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8443 so that any alterations it does to the resulting string will be
8444 available in stringlib/formatter.h (for float.__format__).
8445
Eric Smith5a3c1352008-02-19 13:21:56 +00008446- Implemented PEP 3101, Advanced String Formatting. This adds a new
8447 builtin format(); a format() method for str and unicode; a
8448 __format__() method to object, str, unicode, int, long, float, and
8449 datetime; the class string.Formatter; and the C API
8450 PyObject_Format().
8451
Georg Brandl3ee81df2008-05-17 18:14:43 +00008452- Fixed several potential crashes, all caused by specially crafted
8453 __del__ methods exploiting objects in temporarily inconsistent
8454 state.

8465 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008466
Georg Brandl3ee81df2008-05-17 18:14:43 +00008467- Issue #2045: Fix an infinite recursion triggered when printing a
8468 subclass of collections.defaultdict, if its default_factory is set
8469 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008470
Christian Heimesf75dbef2008-02-08 00:11:31 +00008471- Fixed a minor memory leak in dictobject.c. The content of the free
8472 list was not freed on interpreter shutdown.
8473

8478 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008479 to compact the internal free lists of pre-allocted ints and floats.
8480
Georg Brandl3ee81df2008-05-17 18:14:43 +00008481- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8482 calls. Python expected the return type int but the fork familie
8483 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008491- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8492 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008493
Georg Brandl3ee81df2008-05-17 18:14:43 +00008494- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8495 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008496
Georg Brandl3ee81df2008-05-17 18:14:43 +00008497- Patch #1473257: generator objects gain a gi_code attribute. This is
8498 the same object as the func_code attribute of the function that
8499 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008500
Georg Brandl3ee81df2008-05-17 18:14:43 +00008501- Issue #1920: "while 0" statements were completely removed by the
8502 compiler, even in the presence of an "else" clause, which is
8503 supposed to be run when the condition is false. Now the compiler
8504 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008505
Guido van Rossumeead05f2008-01-24 18:21:02 +00008506- A few crashers fixed: weakref_in_del.py (issue #1377858);
8507 loosing_dict_ref.py (issue #1303614, test67.py);
8508 borrowed_ref_[34].py (not in tracker).
8509
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008510- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008511 suppressed while an extension is loaded by calling SetErrorMode in
8512 dynload_win.c. The error is still reported properly.
8513
Georg Brandl3ee81df2008-05-17 18:14:43 +00008514- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008515 several extension methods and modules do not work without unicode
8516 support.
8517
Georg Brandl26543b12008-01-21 18:36:51 +00008518- Issue #1882: when compiling code from a string, encoding cookies in the
8519 second line of code were not always recognized correctly.
8520
Georg Brandl14404b62008-01-19 19:27:05 +00008521- Issue #1679: "0x" was taken as a valid integer literal.
8522
Georg Brandl6caad7d2008-01-26 14:19:22 +00008523- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008524 added.
8525
Christian Heimesc94e2b52008-01-14 04:13:37 +00008526- sys.float_info / PyFloat_GetInfo: The floating point information
8527 object was converted from a dict to a specialized structseq object.
8528
Georg Brandl3ee81df2008-05-17 18:14:43 +00008529- Patch #1816: Added sys.flags structseq. It exposes the status of
8530 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008531
Georg Brandl3ee81df2008-05-17 18:14:43 +00008532- Objects/structseq.c: Implemented new structseq representation. The
8533 patch makes structseqs (e.g. the return value of os.stat) more
8534 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008535
Georg Brandl3ee81df2008-05-17 18:14:43 +00008536- Patch #1700288: added a type attribute cache that caches method
8537 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008538
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008539- Bug #1776: __import__() no longer accepts filenames on any platform.
8540 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008541
Georg Brandlaed6c662008-01-07 17:25:53 +00008542- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8543
Georg Brandl3ee81df2008-05-17 18:14:43 +00008544- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8545 envvar and sys.dont_write_bytecode attribute. All these can be set
8546 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008547
Georg Brandl3ee81df2008-05-17 18:14:43 +00008548- Improve some exception messages when Windows fails to load an
8549 extension module. Now we get for example '%1 is not a valid Win32
8550 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008551
Georg Brandl3ee81df2008-05-17 18:14:43 +00008552- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008554- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8555 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008556
Christian Heimes0a8143f2007-12-18 23:22:54 +00008557- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008558 and INF. float("nan"), float("inf") and float("-inf") now work on
8559 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008560
Georg Brandl3ee81df2008-05-17 18:14:43 +00008561- Compiler now generates simpler and faster code for dictionary
8562 literals. The oparg for BUILD_MAP now indicates an estimated
8563 dictionary size. There is a new opcode, STORE_MAP, for adding
8564 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008565
Georg Brandl3ee81df2008-05-17 18:14:43 +00008566- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008571- Issue #1538: Avoid copying string in split/rsplit if the split char
8572 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008573
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008574- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008575 SystemError.
8576
Nick Coghlanef01d822007-12-03 12:55:17 +00008577- PEP 366: Allow explicit relative imports when executing modules
8578 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00008593- Patch #1739468: Directories and zipfiles containing a __main__.py
8594 file can now be directly executed by passing their name to the
8595 interpreter. The directory/zipfile is automatically inserted as the
8596 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008597
Georg Brandl3ee81df2008-05-17 18:14:43 +00008598- Issue #1265: Fix a problem with sys.settrace, if the tracing
8599 function uses a generator expression when at the same time the
8600 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008601
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008602- sets and frozensets now have an isdisjoint() method.
8603
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008604- optimize the performance of builtin.sum().
8605
Neal Norwitz44f326e2007-10-05 05:29:17 +00008606- Fix warnings found by the new version of the Coverity checker.
8607
Georg Brandl21e99f42010-03-07 15:23:59 +00008608- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008609 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8610 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008611
Georg Brandl3ee81df2008-05-17 18:14:43 +00008612- Issue #1686386: Tuple's tp_repr did not take into account the
8613 possibility of having a self-referential tuple, which is possible
8614 from C code. Nor did object's tp_str consider that a type's tp_str
8615 could do something that could lead to an inifinite recursion.
8616 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8617 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008618
Georg Brandl3ee81df2008-05-17 18:14:43 +00008619- Issue #1164: It was possible to trigger deadlock when using the
8620 'print' statement to write to a file since the GIL was not released
8621 as needed. Now PyObject_Print() does the right thing along with
8622 various tp_print implementations of the built-in types and those in
8623 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008624
Georg Brandl3ee81df2008-05-17 18:14:43 +00008625- Issue #1147: Exceptions were directly allowing string exceptions in
8626 their throw() method even though string exceptions no longer
8627 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008628
Georg Brandl3ee81df2008-05-17 18:14:43 +00008629- Issue #1096: Prevent a segfault from getting the repr of a very
8630 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008631
Brett Cannon1e534b52007-09-07 04:18:30 +00008632- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008633 PyObject_Call() never calling back out to Python code to trigger
8634 recursion depth updates/checks. Required the creation of a static
8635 RuntimeError instance in case normalizing an exception put the
8636 recursion check value past its limit. Fixes crashers
8637 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008638
Georg Brandl3ee81df2008-05-17 18:14:43 +00008639- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008652- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008653 __*__ attributes. (Some already existed, e.g., __doc__ and
8654 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008655
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008656- Add -3 option to the interpreter to warn about features that are
8657 deprecated and will be changed/removed in Python 3.0.
8658
Georg Brandl2134e752007-05-21 20:34:16 +00008659- Patch #1686487: you can now pass any mapping after '**' in function
8660 calls.
8661
Collin Winter62903052007-05-18 23:11:24 +00008662- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008663 "except E as target:". This is to provide forwards compatibility
8664 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008665
Brett Cannon229cee22007-05-05 01:34:02 +00008666- Deprecate BaseException.message as per PEP 352.
8667
Georg Brandl3ee81df2008-05-17 18:14:43 +00008668- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008669 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008670
Vinay Sajip8549ce32007-05-06 17:53:37 +00008671- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008672 setting a plain string, ie don't expand to single letter identifiers.
8673
Raymond Hettinger13936692007-04-11 18:40:58 +00008674- Request #1191699: Slices can now be pickled.
8675
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008676- Request #1193128: str.translate() now allows a None argument for
8677 translations that only remove characters without re-mapping the
8678 remaining characters.
8679
Georg Brandl5cb76c12007-03-21 09:00:39 +00008680- Patch #1682205: a TypeError while unpacking an iterable is no longer
8681 masked by a generic one with the message "unpack non-sequence".
8682
Neal Norwitzaa754b72007-03-21 06:39:48 +00008683- Remove unused file Python/fmod.c.
8684
Guido van Rossum143b5642007-03-23 04:58:42 +00008685- Bug #1683368: The object.__init__() and object.__new__() methods are
8686 now stricter in rejecting excess arguments. The only time when
8687 either allows excess arguments is when it is not overridden and the
8688 other one is. For backwards compatibility, when both are
8689 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008690 warning later). Also, type.__init__() insists on the same signature
8691 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008692
Georg Brandl3ee81df2008-05-17 18:14:43 +00008693- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8694 object to complex using its __complex__() method before falling back
8695 to the __float__() method. Therefore, the functions in the cmath
8696 module now can operate on objects that define a __complex__()
8697 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008698
Georg Brandl3ee81df2008-05-17 18:14:43 +00008699- Patch #1623563: allow __class__ assignment for classes with
8700 __slots__. The old and the new class are still required to have the
8701 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008702

8707 ``object.__reduce_ex__()`` is called with an object that is faking
8708 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008709
Georg Brandl3ee81df2008-05-17 18:14:43 +00008710- Patch #1680015: Don't modify __slots__ tuple if it contains an

8714
Georg Brandl7b9c5552007-03-12 14:30:05 +00008715- Bug #1678647: write a newline after printing an exception in any
8716 case, even when converting the value to a string failed.
8717
Georg Brandl871f1bc2007-03-12 13:17:36 +00008718- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008719 its argument, if it exists. If not, it will work like before. This
8720 allows customizing the output of dir() in the presence of a
8721 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008723- Patch #922167: Python no longer segfaults when faced with infinitely
8724 self-recursive reload() calls (as reported by bug #742342).
8725
Georg Brandl3ee81df2008-05-17 18:14:43 +00008726- Patch #1675981: remove unreachable code from ``type.__new__()``
8727 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00008728
Georg Brandl3ee81df2008-05-17 18:14:43 +00008729- Patch #1491866: change the complex() constructor to allow

9241 ".cpp" too.
9242
Facundo Batistad918a652007-04-24 13:54:38 +00009243- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009244 the client's request was successfully received, understood, and
9245 accepted. Now in these cases no error is raised in urllib (issue
9246 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00009247

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009254- Added a timeout parameter to the constructor of other protocols
9255 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9256 work started with create_connection() and timeout in httplib, and
9257 closes patch #723312.
9258
Vinay Sajip8549ce32007-05-06 17:53:37 +00009259- Patch #1676823: Added create_connection() to socket.py, which may be
9260 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00009261 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00009262
Martin v. Löwis0af33882007-03-23 13:27:15 +00009263- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009270- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
9271 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00009272 directories.
9273

9275 GNOME or KDE browser, depending on whether there is a session of one
9276 of those present. Also, it tries the Windows default browser before
9277 trying Mozilla variants.

9283
Georg Brandlf66b6032007-03-14 08:27:52 +00009284- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00009285 AttributeError instead of an IOError when the server's response
9286 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009287
Georg Brandl3ee81df2008-05-17 18:14:43 +00009288- Patch #957650: "%var%" environment variable references are now
9289 properly expanded in ntpath.expandvars(), also "~user" home
9290 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00009291
Georg Brandl3ee81df2008-05-17 18:14:43 +00009292- Patch #1429539: pdb now correctly initializes the __main__ module
9293 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009294 correctly now.
9295
Georg Brandlbad6f192007-03-13 21:32:56 +00009296- The nonobvious commands.getstatus() function is now deprecated.

9302
Georg Brandl3ee81df2008-05-17 18:14:43 +00009303- Patch #1530482: add pydoc.render_doc() which returns the
9304 documentation for a thing instead of paging it to stdout, which
9305 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00009306
Georg Brandl3ee81df2008-05-17 18:14:43 +00009307- Patch #1533909: the timeit module now accepts callables in addition

9313 parameter which can be set to False to prevent the default
9314 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00009315
Georg Brandl9e6b4702007-03-13 18:15:41 +00009316- Patch #1581073: add a flag to textwrap that prevents the dropping of
9317 whitespace while wrapping.
9318
Georg Brandl92a6bae2007-03-13 17:43:32 +00009319- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009320 are set for invalid interpolation sequences that would lead to
9321 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009322

9335
Georg Brandl94fe3f52007-03-13 09:32:11 +00009336- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00009337 field names in its exception message if you try to write a record
9338 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00009356

9364 returned string up to the first NUL character.
9365

9375
Georg Brandl3ee81df2008-05-17 18:14:43 +00009376- unittest now verifies more of its assumptions. In particular,
9377 TestCase and TestSuite subclasses (not instances) are no longer
9378 accepted in TestSuite.addTest(). This should cause no
9379 incompatibility since it never made sense with ordinary subclasses
9380 -- the failure just occurred later, with a more cumbersome
9381 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00009382

9390 given a unicode argument and os.listdir() returns unicode filenames.
9391
Georg Brandl3ee81df2008-05-17 18:14:43 +00009392- Patch #1673619: setup.py identifies extension modules it doesn't

9394 build.

9746 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9747 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009764 time so that opening a database previously created with the DB_DUP
9765 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9766 opens. Specifically: dictionary assignment to a DB object will
9767 replace all values for a given key when the database allows
9768 duplicate values. DB users should use DB.put(k, v) when they want
9769 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009770

9776 characters with ASCII value less than 32. Also, it correctly quotes
9777 dots only if they occur on a single line, as opposed to the previous
9778 behavior of quoting dots if they are the second character of any
9779 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009780
