1129 32-bit-only installer Pythons on systems with Xcode 4 (currently
1130 OS X 10.8, 10.7, and optionally 10.6).
1131 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1132 * Since Xcode 4 removes ppc support, extension module builds now
1133 check for ppc compiler support and by default remove ppc and
1134 ppc64 archs when they are not available.
1135 * Extension module builds now revert to using system installed
1136 headers and libs (/usr and /System/Library) if the SDK used
1137 to build the interpreter is not installed or has moved.
1138 * Try to avoid building extension modules with deprecated
1139 and problematic Apple llvm-gcc compiler. If original compiler
1140 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001491- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1492 int.__pow__. These overflow checks were causing int.__pow__ to produce
1493 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001494 compiler optimizing the check away. Also fix similar overflow checks
1495 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1496 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001564- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001565 has left two versions of customize_compiler, the original in
1566 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001571- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1572 Distutils-based packages with C extension modules may fail because
1573 Apple has removed gcc-4.2, the version used to build python.org
1574 64-bit/32-bit Pythons. If the user does not explicitly override
1575 the default C compiler by setting the CC environment variable,
1576 Distutils will now attempt to compile extension modules with clang
1577 if gcc-4.2 is required but not found. Also as a convenience, if
1578 the user does explicitly set CC, substitute its value as the default
1579 compiler in the Distutils LDSHARED configuration variable for OS X.
1580 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1581 SDK, neither of which are available in Xcode 4. This change does not
1582 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001832- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1833 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1834 interpreter process. This could cause failures in non-Distutils subprocesses
1835 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001836 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001837 deployment target only in the environment of each build subprocess. It is
1838 still possible to globally override the default by setting
1839 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1840 greater or equal to the default value, the value with which the interpreter
1841 was built.

1870 updating the check interval, so if the user decreases the check interval,
1871 the ticker doesn't have to wind down to zero from the old starting point
1872 before the new interval takes effect. And if the user increases the
1873 interval, it makes sure the new limit takes effect right away rather have an
1874 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002854- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2855 This prevents user-created self-referencing ordered dictionaries from
2856 becoming permanently uncollectable GC garbage. The downside is that
2857 removing __del__ means that the internal doubly-linked list has to wait for
2858 GC collection rather than freeing memory immediately when the refcnt drops
2859 to zero.

2867 to fetch the original errno, or to filter timeout errors. Now the
2868 original error is re-raised.

3317
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003318- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3319 start byte and the continuation byte(s) are now considered invalid, instead
3320 of the number of bytes specified by the start byte.
3321 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3322 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3323 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3324 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003332- Issue #8748: Fix two issues with comparisons between complex and integer
3333 objects. (1) The comparison could incorrectly return True in some cases
3334 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3335 (2) The comparison raised an OverflowError for large integers, leading
3336 to unpredictable exceptions when combining integers and complex objects
3337 in sets or dicts.
3338
Mark Dickinson81336372010-05-30 12:12:25 +00003339- Issue #5211: Implicit coercion for the complex type is now completely
3340 removed. (Coercion for arithmetic operations was already removed in 2.7

Georg Brandlba83f822010-03-14 09:50:54 +00004217 file position when calling `truncate()`. It would previously change the file
4218 position to the given argument, which goes against the tradition of

4314-----------------
4315
Georg Brandlba83f822010-03-14 09:50:54 +00004316- The ``__complex__()`` method is now looked up on the class of instances to
4317 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004319- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4320 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4321
Mark Dickinson1b34d252010-01-01 17:27:30 +00004322- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004323 DeprecationWarning when passed a float argument where an integer was expected.
4324 These functions and methods now raise TypeError instead. The majority of the
4325 effects of this change are in the extension modules, but some core functions
4326 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4327 and many unicode/str methods.

4338 used to drop the time part of the result.
4339
Georg Brandlba83f822010-03-14 09:50:54 +00004340- Issue #1811: Improve accuracy and cross-platform consistency for true division
4341 of integers: the result of a/b is now correctly rounded for ints a and b (at
4342 least on IEEE 754 platforms), and in particular does not depend on the
4343 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004350 executables on OSX.
4351
Georg Brandlba83f822010-03-14 09:50:54 +00004352 These executables now work properly with the arch(1) command: ``arch -ppc
4353 python`` will start a universal binary version of python in PPC mode (unlike
4354 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004510- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4511 decimal string that's guaranteed to round back to x under correct rounding
4512 (with round-half-to-even rounding mode). Previously it gave a string based on
4513 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4514 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4515 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004516
Georg Brandlba83f822010-03-14 09:50:54 +00004517- Issue #7117: On almost all platforms: float-to-string and string-to-float
4518 conversions within Python are now correctly rounded. Places these conversions
4519 occur include: str for floats and complex numbers; the float and complex
4520 constructors; old-style and new-style numeric formatting; serialization and
4521 deserialization of floats and complex numbers using marshal, pickle and json;
4522 parsing of float and imaginary literals in Python code; Decimal-to-float
4523 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004524
Georg Brandlba83f822010-03-14 09:50:54 +00004525 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4526 providing correctly-rounded strtod and dtoa C functions. This code is
4527 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4528 the C compiler. There may be a small number of platforms on which correct
4529 operation of this code cannot be guaranteed, so the code is not used: notably,
4530 this applies to platforms where the C double format is not IEEE 754 binary64,
4531 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4532 and Python's configure script is unable to determine how to change the FPU
4533 precision. On these platforms conversions use the platform strtod and dtoa,
4534 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004536- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4537 uses the correctly-rounded string <-> float conversions described above (when
4538 available), and so produces correctly rounded results that will display nicely
4539 under the float repr. There are two related small changes: (1) round now
4540 accepts any class with an ``__index__()`` method for its second argument (but
4541 no longer accepts floats for the second argument), and (2) an excessively
4542 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4543 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004685
Georg Brandlba83f822010-03-14 09:50:54 +00004686 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4687 (2) parsing of strings representing infinities and nans was locale aware; and
4688 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004690- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4691 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4692 but with at least one decimal point and with a default precision
4693 of 12. Previously, the behavior the same but with a default precision of 6.
4694 This more closely matches ``str()``, and reduces surprises when adding
4695 alignment flags to the empty presentation type. This also affects the new
4696 complex.__format__ in the same way.
4697
4698- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4896 the file object behaves like a closed file. The ``FileIO`` object also got a
4897 new readonly attribute ``closefd``.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004948- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4949 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4950 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4951 of using the replace error handler in PyUnicode_DecodeUTF8().
4952
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004953- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004956- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4958 gives improved memory leak detection when running under Valgrind, while taking
4959 advantage of pymalloc at other times.

6129 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6130 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006327- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6328
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006329- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6330 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6331 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6332 ``printf`` function, whereas PyString_FromFormat has an independent
6333 implementation and uses "%zd" on all platforms for size_t values.
6334 This makes a difference on win64, where ``printf`` needs "%Id" to display
6335 64bit values.

6341 object; previously an int would be returned for small values. the __long__
6342 method is allowed to return either an int or a long, but the behaviour of
6343 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006352 was correctly parsed but parsing of subsequent arguments failed.
6353
Vinay Sajip35e3b032008-09-01 14:33:59 +00006354- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006355 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6356 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6357 when given a tuple of classes as second argument, were looking up
6358 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6359 type object.

6504-----------------
6505
Guido van Rossumf8402962008-08-20 15:01:50 +00006506- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6507 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6508 extensions do not automatically benefit from the class attribute
6509 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6510 to their tp_flags field if they care. This is a backwards
6511 compatibility feature; in 3.0, all types will use the cache by
6512 default.
6513
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006514- Keyword arguments can now follow starred arguments. (``f(a, *args,
6515 keyword=23)`` is now valid syntax.)
6516
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006517- ctypes function pointers that are COM methods have a boolean True
6518 value again.
6519
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006520- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6521 by denying s# to parse objects that have a releasebuffer procedure,
6522 and introducing s*.
6523
Georg Brandl1e13ea92008-08-11 09:07:59 +00006524- Issue #3537: Fix an assertion failure when an empty but presized dict
6525 object was stored in the freelist.
6526
Mark Dickinsonb6467572008-08-04 21:30:09 +00006527- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6528 ValueError consistently across platforms.
6529
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006530- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6531 (64bit Unix, for example), unichr() would truncate its argument and return
6532 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6533
Neal Norwitze7d8be82008-07-31 17:17:14 +00006534- Apply security patches from Apple.
6535
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006536- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

6538
Antoine Pitrou92f82162008-07-25 22:22:08 +00006539- Issue #1819: function calls with several named parameters are now on
6540 average 35% faster (as measured by pybench).
6541
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006542- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6543 the python debugger steps into a class statement: the free variables (local
6544 variables defined in an outer scope) would be deleted from the outer scope.
6545
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006546- Issue #2620: Overflow checking when allocating or reallocating memory
6547 was not always being done properly in some python types and extension
6548 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6549 all been updated to perform better checks and places in the code that
6550 would previously leak memory on the error path when such an allocation
6551 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006556- Issue #3612: Added some missing basic types in ctypes.wintypes.
6557
Benjamin Petersone977ad42008-08-20 01:42:01 +00006558- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6559 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6560
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006561- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6562 version reported by these tools does not necessarily follow the python
6563 version numbering scheme, so the module is less strict when parsing it.
6564
Nick Coghlanf70385a2008-08-18 12:42:46 +00006565- Issue #2235: Added Py3k warnings for types which will become unhashable
6566 under the stricter __hash__ inheritance rules in 3.0. Several types
6567 which did not meet the rules for hash invariants and were already
6568 unhashable in 3.0 have now been explicitly flagged as unhashable in
6569 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6570 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6571
Brett Cannon88f801d2008-08-18 00:46:22 +00006572- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6573 imported into the module but exposed as part of the module's API.
6574
Brett Cannon7b96f072008-08-18 00:41:11 +00006575- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6576
Brett Cannon46225e72008-08-18 00:36:52 +00006577- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006579- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6580
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006581- Issue #3575: Incremental decoder's decode function now takes bytearray
6582 by using 's*' instead of 't#'.
6583
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006584- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006585 fails unicode conversion on 2nd parameter. (windows only)
6586
Georg Brandl222e2082010-08-01 22:27:39 +00006587- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006588 in a redirect.
6589
Brett Cannonabe423e2008-08-16 21:47:07 +00006590- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006591 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006592
Facundo Batistaeb90b782008-08-16 14:44:07 +00006593- Issue #2776: fixed small issue when handling an URL with double slash
6594 after a 302 response in the case of not going through a proxy.
6595
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006596- Issue #2676: in the email package, content-type parsing was hanging on
6597 pathological input because of quadratic or exponential behaviour of a
6598 regular expression.
6599
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006600- Issue #3476: binary buffered reading through the new "io" library is now
6601 thread-safe.
6602
Brett Cannonbf3157b2008-08-14 05:00:03 +00006603- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6604 since mimetools itself is deprecated. Because modules are cached, all
6605 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6606
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006607- Issue #3134: shutil referenced undefined WindowsError symbol.
6608
Robert Schuppenies14646332008-08-10 11:01:53 +00006609- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6610 menu entries were not deleted.
6611
Brett Cannon83e81842008-08-09 23:30:55 +00006612- Copied the implementation of reduce() to _functools.reduce() to have a
6613 version that did not raise a DeprecationWarning under -3.
6614
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006615- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6616 a MemoryError rather than silently stop the iteration.
6617
Guido van Rossum59ce9012008-08-09 14:55:34 +00006618- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6619 to _sre.compile() will now be rejected. This should not affect anybody
6620 since the re.compile() function never generates invalid re-bytecode.
6621
Skip Montanaroa032bf42008-08-08 22:52:51 +00006622- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6623 upon first access it can be automatically initialized from the csv file if
6624 it wasn't initialized during instantiation.
6625
Brett Cannon3aa2a492008-08-06 22:28:09 +00006626- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6627 the reload() built-in has been removed.
6628
Brett Cannon7e30b672008-08-04 21:52:25 +00006629- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006630 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6638 raised an AttributeError.
6639
Benjamin Peterson01a24322008-07-28 23:35:27 +00006640- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006641 asking for a specific length. This problem only affected files opened
6642 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006643
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006644- Issue #3449: Update decimal module to use most recent specification
6645 (v. 1.68) and tests (v. 2.58) from IBM.
6646
Georg Brandl222e2082010-08-01 22:27:39 +00006647- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

6666
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006667- Issue #3394: zipfile.writestr sets external attributes when passed a
6668 file name rather than a ZipInfo instance, so files are extracted with
6669 mode 0600 rather than 000 under Unix.
6670
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006671- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6672 argument in python 2.5, this broke code that subclassed Popen to include its
6673 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006683- Issue #2235: the C API function PyObject_HashNotImplemented and its
6684 interaction with the tp_hash slot (added in 2.6b2) are now documented
6685
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006686- Issue #643841: The language reference now provides more detailed
6687 coverage of the lookup process for special methods. The disclaimers
6688 regarding lack of coverage of new-style classes have also been
6689 removed, since the coverage is now fairly reasonable.

6693================================
6694
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006695*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006697Core and Builtins
6698-----------------
6699
Georg Brandl3e483f62008-07-16 22:57:41 +00006700- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6701 its methods now allow for items objects that can be converted to
6702 an integer using operator.index().
6703
Mark Dickinson64b7e502008-07-16 09:40:03 +00006704- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6705 produced a ValueError instead of giving the correct float.
6706
Eric Smitha5fa5a22008-07-16 00:11:49 +00006707- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6708 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6709
Mark Dickinson7103aa42008-07-15 19:08:33 +00006710- Issue #3008: the float type has a new instance method 'float.hex'
6711 and a new class method 'float.fromhex' to convert floating-point
6712 numbers to and from hexadecimal strings, respectively.
6713
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006714- Issue #2235: __hash__ is once again inherited by default. To allow
6715 collections.Hashable to remain meaningful in the presence of the
6716 default hash implementation (object.__hash__), it is now possible
6717 to explicit block inheritance of hash by setting __hash__=None at
6718 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6719 level.
6720
Nick Coghlanb028f502008-07-13 14:52:36 +00006721- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6722 the parent module cannot be found while performing an absolute import.
6723 This means that an incorrectly defined __package__ attribute will
6724 now only prevent relative imports in that module rather than causing
6725 all imports from that module to fail.
6726
Nick Coghlan14ff9942008-07-08 14:21:42 +00006727- Issue #2517: Allow unicode messages in Exceptions again by correctly
6728 bypassing the instance dictionary when looking up __unicode__ on
6729 new-style classes.
6730
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006731- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6732 set to a custom object whose write() method happens to install
6733 another file in sys.stdout.
6734
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006735- Issue #3088: Corrected a race condition in classes derived from
6736 threading.local: the first member set by a thread could be saved in
6737 another thread's dictionary.
6738
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006739- Issue #3004: Minor change to slice.indices(): the start and stop
6740 arguments are now treated identically, making the behaviour easier
6741 to describe and understand. For example, slice(None, -10,
6742 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6743 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6744 10, -1).
6745
Georg Brandl278fc502008-07-19 12:46:12 +00006746- Issue #3219: Calling a function with repeated keyword arguments,
6747 f(a=2, a=23), would not cause a syntax error. This was a regression
6748 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006749
Georg Brandl278fc502008-07-19 12:46:12 +00006750- Issue #2862: Make int and float freelist management consistent with
6751 other freelists. Changes their CompactFreeList apis into
6752 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006753

6755-------
6756
Thomas Heller57adf222008-08-14 19:10:48 +00006757- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6758 api functions without holding the GIL, which could lead to a fatal
6759 error when they failed.
6760
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006761- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006769- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6770 ForkingPickler.register() to resolve conflict with ctypes.
6771
Vinay Sajip51e65192008-07-18 09:01:10 +00006772- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00006774- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6775 a valid dlerror() message.
6776
Thomas Heller2bad6572008-07-15 17:19:50 +00006777- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6778 incomplete structure was created.
6779

6783
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006784- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006785
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006786- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6787 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006788 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006789 content-length. The problem had been corrected in the 2.4 branch, but never
6790 merged into trunk.
6791

Facundo Batista66c52772008-07-02 16:52:55 +00006804
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006805- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6806 handling is now the same as that of other special attributes like __name__).
6807
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006808- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6820 default https port (443).
6821
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00006822- Issue #874900: after an os.fork() call the threading module state is cleaned

7195
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007196- On MacOS X it is now possible to install the framework in 64-bit
7197 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007198 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007199
7200 This is controlled by the configure argument ``--with-universal-archs``:
7201
7202 - ``--with-universal-archs=all``: install 4-way universal
7203
7204 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7205
7206 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7207
7208 This option should be used in combination with ``--enable-universalsdk=``.
7209
7210 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007260- Issue #1631171: Re-implement the 'warnings' module in C (the
7261 original Python code has been kept as backup). This will allow for
7262 using the 'warning's machinery in such places as the parser where
7263 use of pure Python code is not possible. Both the ``showarning()``
7264 and ``formatwarning()`` gain an optional 'line' argument which is
7265 not called by default for backwards-compatibility reasons. Setting
7266 ``warnings.showwarning()`` to an implementation that lacks support
7267 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007330- Issue #2550: The approach used by client/server code for obtaining
7331 ports to listen on in network-oriented tests has been refined in an
7332 effort to facilitate running multiple instances of the entire
7333 regression test suite in parallel without issue.
7334 test_support.bind_port() has been fixed such that it will always
7335 return a unique port -- which wasn't always the case with the
7336 previous implementation, especially if socket options had been set
7337 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7338 new implementation of bind_port() will actually raise an exception
7339 if it is passed an AF_INET/SOCK_STREAM socket with either the
7340 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7341 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7342 the socket it's been passed. This currently only applies to
7343 Windows. This option prevents any other sockets from binding to the
7344 host/port we've bound to, thus removing the possibility of the
7345 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7346 when a second SOCK_STREAM socket binds and accepts to a host/port
7347 that's already been bound by another socket. The optional preferred
7348 port parameter to bind_port() has been removed. Under no
7349 circumstances should tests be hard coding ports!
7350
7351 test_support.find_unused_port() has also been introduced, which will
7352 pass a temporary socket object to bind_port() in order to obtain an
7353 unused port. The temporary socket object is then closed and
7354 deleted, and the port is returned. This method should only be used
7355 for obtaining an unused port in order to pass to an external program
7356 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7357 a parameter to a server-oriented class that doesn't give you direct
7358 access to the underlying socket used.
7359
7360 Finally, test_support.HOST has been introduced, which should be used
7361 for the host argument of any relevant socket calls (i.e. bind and
7362 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007363
7364 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007365 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007366 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7367 test_asynchat and test_socket_ssl.
7368
Georg Brandl3ee81df2008-05-17 18:14:43 +00007369 It is now possible for multiple instances of the regression test
7370 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00007645
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007646- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007647 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007648
Eric Smitha73fbe72008-02-23 03:09:44 +00007649- Added the future_builtins module, which contains hex() and oct().
7650 These are the PEP 3127 version of these functions, designed to be
7651 compatible with the hex() and oct() builtins from Python 3.0. They
7652 differ slightly in their output formats from the existing, unchanged
7653 Python 2.6 builtins. The expected usage of the future_builtins
7654 module is:
7655 from future_builtins import hex, oct
7656
Eric Smith7ef40bf2008-02-20 23:34:22 +00007657- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7658 exponents for exponents with absolute value < 100. Follows C99
7659 standard. This is a change on Windows, which would use 3 digits.
7660 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7661 so that any alterations it does to the resulting string will be
7662 available in stringlib/formatter.h (for float.__format__).
7663
Eric Smith5a3c1352008-02-19 13:21:56 +00007664- Implemented PEP 3101, Advanced String Formatting. This adds a new
7665 builtin format(); a format() method for str and unicode; a
7666 __format__() method to object, str, unicode, int, long, float, and
7667 datetime; the class string.Formatter; and the C API
7668 PyObject_Format().
7669
Georg Brandl3ee81df2008-05-17 18:14:43 +00007670- Fixed several potential crashes, all caused by specially crafted
7671 __del__ methods exploiting objects in temporarily inconsistent
7672 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007673
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007674- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007675 prevent a possible crash: an Abstract Base Class would try to access
7676 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007677
Georg Brandl3ee81df2008-05-17 18:14:43 +00007678- Fixed repr() and str() of complex numbers with infinity or nan as
7679 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007680
Georg Brandl3ee81df2008-05-17 18:14:43 +00007681- Clear all free lists during a gc.collect() of the highest generation
7682 in order to allow pymalloc to free more arenas. Python may give back
7683 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007684
Georg Brandl3ee81df2008-05-17 18:14:43 +00007685- Issue #2045: Fix an infinite recursion triggered when printing a
7686 subclass of collections.defaultdict, if its default_factory is set
7687 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007688
Christian Heimesf75dbef2008-02-08 00:11:31 +00007689- Fixed a minor memory leak in dictobject.c. The content of the free
7690 list was not freed on interpreter shutdown.
7691
Georg Brandl21e99f42010-03-07 15:23:59 +00007692- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007693 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007694
Georg Brandl3ee81df2008-05-17 18:14:43 +00007695- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7696 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007697 to compact the internal free lists of pre-allocted ints and floats.
7698
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7700 calls. Python expected the return type int but the fork familie
7701 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007702
Georg Brandl3ee81df2008-05-17 18:14:43 +00007703- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7704 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007705
Georg Brandl3ee81df2008-05-17 18:14:43 +00007706- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7707 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007708
Georg Brandl3ee81df2008-05-17 18:14:43 +00007709- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7710 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007711
Georg Brandl3ee81df2008-05-17 18:14:43 +00007712- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7713 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Patch #1473257: generator objects gain a gi_code attribute. This is
7716 the same object as the func_code attribute of the function that
7717 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007718
Georg Brandl3ee81df2008-05-17 18:14:43 +00007719- Issue #1920: "while 0" statements were completely removed by the
7720 compiler, even in the presence of an "else" clause, which is
7721 supposed to be run when the condition is false. Now the compiler
7722 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007723
Guido van Rossumeead05f2008-01-24 18:21:02 +00007724- A few crashers fixed: weakref_in_del.py (issue #1377858);
7725 loosing_dict_ref.py (issue #1303614, test67.py);
7726 borrowed_ref_[34].py (not in tracker).
7727
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007728- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007729 suppressed while an extension is loaded by calling SetErrorMode in
7730 dynload_win.c. The error is still reported properly.
7731
Georg Brandl3ee81df2008-05-17 18:14:43 +00007732- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007733 several extension methods and modules do not work without unicode
7734 support.
7735
Georg Brandl26543b12008-01-21 18:36:51 +00007736- Issue #1882: when compiling code from a string, encoding cookies in the
7737 second line of code were not always recognized correctly.
7738
Georg Brandl14404b62008-01-19 19:27:05 +00007739- Issue #1679: "0x" was taken as a valid integer literal.
7740
Georg Brandl6caad7d2008-01-26 14:19:22 +00007741- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007742 added.
7743
Christian Heimesc94e2b52008-01-14 04:13:37 +00007744- sys.float_info / PyFloat_GetInfo: The floating point information
7745 object was converted from a dict to a specialized structseq object.
7746
Georg Brandl3ee81df2008-05-17 18:14:43 +00007747- Patch #1816: Added sys.flags structseq. It exposes the status of
7748 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007749
Georg Brandl3ee81df2008-05-17 18:14:43 +00007750- Objects/structseq.c: Implemented new structseq representation. The
7751 patch makes structseqs (e.g. the return value of os.stat) more
7752 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007753
Georg Brandl3ee81df2008-05-17 18:14:43 +00007754- Patch #1700288: added a type attribute cache that caches method
7755 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007756
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007757- Bug #1776: __import__() no longer accepts filenames on any platform.
7758 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007759

7761
Georg Brandl3ee81df2008-05-17 18:14:43 +00007762- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7763 envvar and sys.dont_write_bytecode attribute. All these can be set
7764 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007765
Georg Brandl3ee81df2008-05-17 18:14:43 +00007766- Improve some exception messages when Windows fails to load an
7767 extension module. Now we get for example '%1 is not a valid Win32
7768 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007769
Georg Brandl3ee81df2008-05-17 18:14:43 +00007770- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007772- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7773 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007774
Christian Heimes0a8143f2007-12-18 23:22:54 +00007775- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007776 and INF. float("nan"), float("inf") and float("-inf") now work on
7777 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007778
Georg Brandl3ee81df2008-05-17 18:14:43 +00007779- Compiler now generates simpler and faster code for dictionary
7780 literals. The oparg for BUILD_MAP now indicates an estimated
7781 dictionary size. There is a new opcode, STORE_MAP, for adding
7782 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007783
Georg Brandl3ee81df2008-05-17 18:14:43 +00007784- Issue #1638: %zd configure test fails on Linux.

7812 file can now be directly executed by passing their name to the
7813 interpreter. The directory/zipfile is automatically inserted as the
7814 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007815
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816- Issue #1265: Fix a problem with sys.settrace, if the tracing
7817 function uses a generator expression when at the same time the
7818 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007819
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007820- sets and frozensets now have an isdisjoint() method.
7821
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007822- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00007824- Fix warnings found by the new version of the Coverity checker.
7825
Georg Brandl21e99f42010-03-07 15:23:59 +00007826- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7828 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007829
Georg Brandl3ee81df2008-05-17 18:14:43 +00007830- Issue #1686386: Tuple's tp_repr did not take into account the
7831 possibility of having a self-referential tuple, which is possible
7832 from C code. Nor did object's tp_str consider that a type's tp_str
7833 could do something that could lead to an inifinite recursion.
7834 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7835 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007836
Georg Brandl3ee81df2008-05-17 18:14:43 +00007837- Issue #1164: It was possible to trigger deadlock when using the
7838 'print' statement to write to a file since the GIL was not released
7839 as needed. Now PyObject_Print() does the right thing along with
7840 various tp_print implementations of the built-in types and those in
7841 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007842
Georg Brandl3ee81df2008-05-17 18:14:43 +00007843- Issue #1147: Exceptions were directly allowing string exceptions in
7844 their throw() method even though string exceptions no longer
7845 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007846

Brett Cannon1e534b52007-09-07 04:18:30 +00007850- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007851 PyObject_Call() never calling back out to Python code to trigger
7852 recursion depth updates/checks. Required the creation of a static
7853 RuntimeError instance in case normalizing an exception put the
7854 recursion check value past its limit. Fixes crashers
7855 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007856

Neal Norwitz0ac60192007-05-27 04:08:54 +00007870- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007871 __*__ attributes. (Some already existed, e.g., __doc__ and
7872 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007873
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007874- Add -3 option to the interpreter to warn about features that are
7875 deprecated and will be changed/removed in Python 3.0.
7876
Georg Brandl2134e752007-05-21 20:34:16 +00007877- Patch #1686487: you can now pass any mapping after '**' in function
7878 calls.
7879
Collin Winter62903052007-05-18 23:11:24 +00007880- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007881 "except E as target:". This is to provide forwards compatibility
7882 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007889- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007890 setting a plain string, ie don't expand to single letter identifiers.
7891
Raymond Hettinger13936692007-04-11 18:40:58 +00007892- Request #1191699: Slices can now be pickled.
7893
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007894- Request #1193128: str.translate() now allows a None argument for
7895 translations that only remove characters without re-mapping the
7896 remaining characters.
7897
Georg Brandl5cb76c12007-03-21 09:00:39 +00007898- Patch #1682205: a TypeError while unpacking an iterable is no longer
7899 masked by a generic one with the message "unpack non-sequence".

7902
Guido van Rossum143b5642007-03-23 04:58:42 +00007903- Bug #1683368: The object.__init__() and object.__new__() methods are
7904 now stricter in rejecting excess arguments. The only time when
7905 either allows excess arguments is when it is not overridden and the
7906 other one is. For backwards compatibility, when both are
7907 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007908 warning later). Also, type.__init__() insists on the same signature
7909 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007911- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7912 object to complex using its __complex__() method before falling back
7913 to the __float__() method. Therefore, the functions in the cmath
7914 module now can operate on objects that define a __complex__()
7915 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007933- Bug #1678647: write a newline after printing an exception in any
7934 case, even when converting the value to a string failed.
7935
Georg Brandl871f1bc2007-03-12 13:17:36 +00007936- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007937 its argument, if it exists. If not, it will work like before. This
7938 allows customizing the output of dir() in the presence of a
7939 __getattr__().

7949 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00007951- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007952 makes the filenames the warning module prints much more sensible
7953 when a PYTHONSTARTUP file is used.

7967 sq_ass_slice instead of the sq_slice slot.
7968
Georg Brandl3ee81df2008-05-17 18:14:43 +00007969- When printing an unraisable error, don't print exceptions. before

8022 embedded in the string to convert.
8023
Georg Brandl846f73a2006-10-08 07:11:54 +00008024- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00008072 generator expressions (x for x, in ... ) works again. Fixing this
8073 problem required changing the .pyc magic number. This means that
8074 .pyc files generated before 2.5c2 will be regenerated.

8873 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008874
Georg Brandl3ee81df2008-05-17 18:14:43 +00008875- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8876 with RFC 3207 and forgets any knowledge obtained from the server not
8877 obtained from the TLS negotiation itself. Patch contributed by Bill
8878 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008879
Georg Brandl3ee81df2008-05-17 18:14:43 +00008880- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008881 that the SMTP.starttls() caller no longer needs to call ehlo()
8882 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008883 does not claim to support starttls. Adds the
8884 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8965 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8966 silently miscode subclasses of those types. Now, it raises a
8967 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008968

Georg Brandl3ee81df2008-05-17 18:14:43 +00008983 time so that opening a database previously created with the DB_DUP
8984 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8985 opens. Specifically: dictionary assignment to a DB object will
8986 replace all values for a given key when the database allows
8987 duplicate values. DB users should use DB.put(k, v) when they want
8988 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008989

8995 characters with ASCII value less than 32. Also, it correctly quotes
8996 dots only if they occur on a single line, as opposed to the previous
8997 behavior of quoting dots if they are the second character of any
8998 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008999
