414 of the number of bytes specified by the start byte.
415 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
416 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

428 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000624- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
625 operation raises multiple signals and more than one of those signals is

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

870 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
871 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000873- Issue #2531: Comparison operations between floats and Decimal instances now
874 return a result based on the numeric values of the operands; previously they
875 returned an arbitrary result based on the relative ordering of id(float) and
876 id(Decimal).

880 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +0000890- Comparisons using one of <, <=, >, >= between a complex instance and a
891 Fractions instance now raise TypeError instead of returning True/False. This
892 makes Fraction <=> complex comparisons consistent with int <=> complex, float
893 <=> complex, and complex <=> complex comparisons.

1405
Georg Brandlba83f822010-03-14 09:50:54 +00001406- The ``__complex__()`` method is now looked up on the class of instances to
1407 make it consistent with other special methods.

1411
Mark Dickinson1b34d252010-01-01 17:27:30 +00001412- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001413 DeprecationWarning when passed a float argument where an integer was expected.
1414 These functions and methods now raise TypeError instead. The majority of the
1415 effects of this change are in the extension modules, but some core functions
1416 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1417 and many unicode/str methods.

1432 least on IEEE 754 platforms), and in particular does not depend on the
1433 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001579- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1580 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00001582- Issue #3382: 'F' formatting for float and complex now convert the result to
1583 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1584 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001585
Georg Brandlba83f822010-03-14 09:50:54 +00001586- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1587 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001588
Georg Brandlba83f822010-03-14 09:50:54 +00001589- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1590 1e-100 used to raise OverflowError, but now gives the requested 120
1591 significant digits instead.

1598 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001599
Georg Brandlba83f822010-03-14 09:50:54 +00001600- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1601 decimal string that's guaranteed to round back to x under correct rounding
1602 (with round-half-to-even rounding mode). Previously it gave a string based on
1603 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1604 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1605 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001606
Georg Brandlba83f822010-03-14 09:50:54 +00001607- Issue #7117: On almost all platforms: float-to-string and string-to-float
1608 conversions within Python are now correctly rounded. Places these conversions
1609 occur include: str for floats and complex numbers; the float and complex
1610 constructors; old-style and new-style numeric formatting; serialization and
1611 deserialization of floats and complex numbers using marshal, pickle and json;
1612 parsing of float and imaginary literals in Python code; Decimal-to-float
1613 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001614
Georg Brandlba83f822010-03-14 09:50:54 +00001615 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1616 providing correctly-rounded strtod and dtoa C functions. This code is
1617 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1618 the C compiler. There may be a small number of platforms on which correct
1619 operation of this code cannot be guaranteed, so the code is not used: notably,
1620 this applies to platforms where the C double format is not IEEE 754 binary64,
1621 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1622 and Python's configure script is unable to determine how to change the FPU
1623 precision. On these platforms conversions use the platform strtod and dtoa,
1624 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001625
Georg Brandlba83f822010-03-14 09:50:54 +00001626- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1627 uses the correctly-rounded string <-> float conversions described above (when
1628 available), and so produces correctly rounded results that will display nicely
1629 under the float repr. There are two related small changes: (1) round now
1630 accepts any class with an ``__index__()`` method for its second argument (but
1631 no longer accepts floats for the second argument), and (2) an excessively
1632 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1633 raises an exception.

1636
Georg Brandlba83f822010-03-14 09:50:54 +00001637- Fix several issues with ``compile()``. The input can now contain Windows and
1638 Mac newlines and is no longer required to end in a newline.

1669 The tables for code points representing numeric values, white spaces or line
1670 breaks are now generated from the official Unicode Character Database files,
1671 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00001780- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1781 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1782 but with at least one decimal point and with a default precision
1783 of 12. Previously, the behavior the same but with a default precision of 6.
1784 This more closely matches ``str()``, and reduces surprises when adding

3412-----------------
3413
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003414- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3415
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003416- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3417 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3418 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3419 ``printf`` function, whereas PyString_FromFormat has an independent
3420 implementation and uses "%zd" on all platforms for size_t values.
3421 This makes a difference on win64, where ``printf`` needs "%Id" to display
3422 64bit values.
3423
Benjamin Peterson97179b02008-09-09 20:55:01 +00003424- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3425 error.
3426
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003427- Issue #3777: long() applied to a float object now always return a long
3428 object; previously an int would be returned for small values. the __long__
3429 method is allowed to return either an int or a long, but the behaviour of
3430 float objects should not change to respect backward compatibility.
3431
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003432- Issue #3751: str.rpartition would perform a left-partition when called with
3433 a unicode argument.
3434
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003435- Issue #3683: Fix compilation when --without-threads is given.
3436
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003437- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003438 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003439 was correctly parsed but parsing of subsequent arguments failed.
3440
Vinay Sajip35e3b032008-09-01 14:33:59 +00003441- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003442 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3443 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3444 when given a tuple of classes as second argument, were looking up
3445 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3446 type object.
3447
Neal Norwitz18aa3882008-08-24 05:04:52 +00003448- Fix crashes on memory allocation failure found with failmalloc.
3449
3450- Fix memory leaks found with valgrind and update suppressions file.
3451
3452- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3453
3454- Fix problem using wrong name in decimal module reported by pychecker.
3455
Christian Heimes7d4c3172008-08-22 19:47:25 +00003456- Silenced another compiler warning about a used but not defined
3457 function 'stringlib_contains_obj'.
3458
Benjamin Peterson712ee922008-08-24 18:10:20 +00003459- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3460 ``__delslice__``.
3461
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003462- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3463 library targets in the Makefile.
3464
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003465- Issue #1204: The configure script now tests for additional libraries
3466 that may be required when linking against readline. This fixes issues
3467 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3468
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00003469C-API

3476
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003477- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3478 stack usage in the case of deeply nested objects.
3479
Guido van Rossume3c4fd92008-09-10 14:27:00 +00003480- Issue #3629: Fix sre "bytecode" validator for an end case.

3487
Vinay Sajip844f7412008-09-09 13:42:08 +00003488- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
3489
Nick Coghland2e09382008-09-11 12:11:06 +00003490- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003491 return a list or None rather than a custom object.
3492
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003493- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3494
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003495- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003517 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3518 for catch_warnings() also led to an improvement in the raising of a
3519 DeprecationWarning related to warnings.warn_explicit().
3520
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003521- The deprecation warnings for the old camelCase threading API were removed.
3522

3543
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003544- Issue #2975: When compiling several extension modules with Visual Studio 2008
3545 from the same python interpreter, some environment variables would grow
3546 without limit.
3547
Benjamin Peterson37346b22008-08-23 20:27:43 +00003548- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3549 exploitation of poor argument checking.
3550
Gerhard Häringef2276b2008-09-12 13:54:06 +00003551- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Nick Coghland2e09382008-09-11 12:11:06 +00003563- Issue #3781: Add test.test_support.check_warnings() as a convenience
3564 wrapper for warnings.catch_warnings() that makes it easier to check
3565 that expected warning messages are being reported.
3566
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003567- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003589
3590Core and Builtins
3591-----------------
3592
Guido van Rossumf8402962008-08-20 15:01:50 +00003593- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3594 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3595 extensions do not automatically benefit from the class attribute
3596 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3597 to their tp_flags field if they care. This is a backwards
3598 compatibility feature; in 3.0, all types will use the cache by
3599 default.
3600
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003601- Keyword arguments can now follow starred arguments. (``f(a, *args,
3602 keyword=23)`` is now valid syntax.)
3603
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003604- ctypes function pointers that are COM methods have a boolean True
3605 value again.
3606
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003607- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3608 by denying s# to parse objects that have a releasebuffer procedure,
3609 and introducing s*.
3610
Georg Brandl1e13ea92008-08-11 09:07:59 +00003611- Issue #3537: Fix an assertion failure when an empty but presized dict
3612 object was stored in the freelist.
3613
Mark Dickinsonb6467572008-08-04 21:30:09 +00003614- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3615 ValueError consistently across platforms.
3616
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003617- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3618 (64bit Unix, for example), unichr() would truncate its argument and return
3619 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3620
Neal Norwitze7d8be82008-07-31 17:17:14 +00003621- Apply security patches from Apple.
3622
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003623- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3624 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3625
Antoine Pitrou92f82162008-07-25 22:22:08 +00003626- Issue #1819: function calls with several named parameters are now on
3627 average 35% faster (as measured by pybench).
3628
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003629- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3630 the python debugger steps into a class statement: the free variables (local
3631 variables defined in an outer scope) would be deleted from the outer scope.
3632
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003633- Issue #2620: Overflow checking when allocating or reallocating memory
3634 was not always being done properly in some python types and extension
3635 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3636 all been updated to perform better checks and places in the code that
3637 would previously leak memory on the error path when such an allocation
3638 failed have been fixed.

3641-------
3642
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003643- Issue #3612: Added some missing basic types in ctypes.wintypes.
3644
Benjamin Petersone977ad42008-08-20 01:42:01 +00003645- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3646 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3647
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003648- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3649 version reported by these tools does not necessarily follow the python
3650 version numbering scheme, so the module is less strict when parsing it.
3651
Nick Coghlanf70385a2008-08-18 12:42:46 +00003652- Issue #2235: Added Py3k warnings for types which will become unhashable
3653 under the stricter __hash__ inheritance rules in 3.0. Several types
3654 which did not meet the rules for hash invariants and were already
3655 unhashable in 3.0 have now been explicitly flagged as unhashable in
3656 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3657 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3658
Brett Cannon88f801d2008-08-18 00:46:22 +00003659- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3667
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003668- Issue #3575: Incremental decoder's decode function now takes bytearray
3669 by using 's*' instead of 't#'.
3670
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003671- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003672 fails unicode conversion on 2nd parameter. (windows only)
3673
Georg Brandl222e2082010-08-01 22:27:39 +00003674- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003675 in a redirect.
3676
Brett Cannonabe423e2008-08-16 21:47:07 +00003677- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003678 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003679
Facundo Batistaeb90b782008-08-16 14:44:07 +00003680- Issue #2776: fixed small issue when handling an URL with double slash
3681 after a 302 response in the case of not going through a proxy.
3682
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003683- Issue #2676: in the email package, content-type parsing was hanging on
3684 pathological input because of quadratic or exponential behaviour of a
3685 regular expression.
3686
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003687- Issue #3476: binary buffered reading through the new "io" library is now
3688 thread-safe.
3689
Brett Cannonbf3157b2008-08-14 05:00:03 +00003690- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3691 since mimetools itself is deprecated. Because modules are cached, all
3692 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3693

Antoine Pitroude781a42008-08-09 12:43:23 +00003728 asking for a specific length. This problem only affected files opened

3772
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003773- Issue #643841: The language reference now provides more detailed

3781
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003782*Release date: 17-Jul-2008*

3785-----------------
3786
Georg Brandl3e483f62008-07-16 22:57:41 +00003787- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3788 its methods now allow for items objects that can be converted to
3789 an integer using operator.index().
3790
Mark Dickinson64b7e502008-07-16 09:40:03 +00003791- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3792 produced a ValueError instead of giving the correct float.
3793
Eric Smitha5fa5a22008-07-16 00:11:49 +00003794- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3795 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3796
Mark Dickinson7103aa42008-07-15 19:08:33 +00003797- Issue #3008: the float type has a new instance method 'float.hex'
3798 and a new class method 'float.fromhex' to convert floating-point
3799 numbers to and from hexadecimal strings, respectively.
3800
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003801- Issue #2235: __hash__ is once again inherited by default. To allow
3802 collections.Hashable to remain meaningful in the presence of the
3803 default hash implementation (object.__hash__), it is now possible
3804 to explicit block inheritance of hash by setting __hash__=None at
3805 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3806 level.
3807
Nick Coghlanb028f502008-07-13 14:52:36 +00003808- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3809 the parent module cannot be found while performing an absolute import.
3810 This means that an incorrectly defined __package__ attribute will
3811 now only prevent relative imports in that module rather than causing
3812 all imports from that module to fail.
3813
Nick Coghlan14ff9942008-07-08 14:21:42 +00003814- Issue #2517: Allow unicode messages in Exceptions again by correctly

3824 another thread's dictionary.
3825
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003826- Issue #3004: Minor change to slice.indices(): the start and stop
3827 arguments are now treated identically, making the behaviour easier
3828 to describe and understand. For example, slice(None, -10,
3829 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3830 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3831 10, -1).
3832
Georg Brandl278fc502008-07-19 12:46:12 +00003833- Issue #3219: Calling a function with repeated keyword arguments,
3834 f(a=2, a=23), would not cause a syntax error. This was a regression
3835 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003836
Georg Brandl278fc502008-07-19 12:46:12 +00003837- Issue #2862: Make int and float freelist management consistent with
3838 other freelists. Changes their CompactFreeList apis into

3845 api functions without holding the GIL, which could lead to a fatal
3846 error when they failed.
3847
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003848- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003873- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3874 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003875 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003876 content-length. The problem had been corrected in the 2.4 branch, but never
3877 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003892- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4261 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00004262
Vinay Sajip9828b7e2008-06-17 11:04:02 +00004263- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004264 environment to control the '-arch' flags that are used to build
4265 an extension. This was added for compatibility with Apple's build
4266 of Python.
4267
4268- The bundled OSX-specific copy of libbffi is now in sync with the version
4269 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4270
Georg Brandl25c34082008-08-18 23:09:49 +00004271- The threading module gained aliases for names that will be removed in the
4272 3.x series.

4280
Brett Cannonb61d8012008-05-11 23:39:04 +00004281- ``Lib/lib-old`` is now added to sys.path.
4282
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004283- On MacOS X it is now possible to install the framework in 64-bit
4284 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004285 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004286
4287 This is controlled by the configure argument ``--with-universal-archs``:
4288
4289 - ``--with-universal-archs=all``: install 4-way universal
4290
4291 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4292
4293 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4294
4295 This option should be used in combination with ``--enable-universalsdk=``.
4296
4297 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 +00004347- Issue #1631171: Re-implement the 'warnings' module in C (the
4348 original Python code has been kept as backup). This will allow for
4349 using the 'warning's machinery in such places as the parser where
4350 use of pure Python code is not possible. Both the ``showarning()``
4351 and ``formatwarning()`` gain an optional 'line' argument which is
4352 not called by default for backwards-compatibility reasons. Setting
4353 ``warnings.showwarning()`` to an implementation that lacks support
4354 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004379- The getpass module has been improved on Unix. It now uses /dev/tty
4380 by default and uses stderr instead of stdout. A GetPassWarning is
4381 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004396- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004397 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004417- Issue #2550: The approach used by client/server code for obtaining
4418 ports to listen on in network-oriented tests has been refined in an
4419 effort to facilitate running multiple instances of the entire
4420 regression test suite in parallel without issue.
4421 test_support.bind_port() has been fixed such that it will always
4422 return a unique port -- which wasn't always the case with the
4423 previous implementation, especially if socket options had been set
4424 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4425 new implementation of bind_port() will actually raise an exception
4426 if it is passed an AF_INET/SOCK_STREAM socket with either the
4427 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4428 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4429 the socket it's been passed. This currently only applies to
4430 Windows. This option prevents any other sockets from binding to the
4431 host/port we've bound to, thus removing the possibility of the
4432 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4433 when a second SOCK_STREAM socket binds and accepts to a host/port
4434 that's already been bound by another socket. The optional preferred
4435 port parameter to bind_port() has been removed. Under no
4436 circumstances should tests be hard coding ports!
4437
4438 test_support.find_unused_port() has also been introduced, which will
4439 pass a temporary socket object to bind_port() in order to obtain an
4440 unused port. The temporary socket object is then closed and
4441 deleted, and the port is returned. This method should only be used
4442 for obtaining an unused port in order to pass to an external program
4443 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4444 a parameter to a server-oriented class that doesn't give you direct
4445 access to the underlying socket used.
4446
4447 Finally, test_support.HOST has been introduced, which should be used
4448 for the host argument of any relevant socket calls (i.e. bind and
4449 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004450
4451 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004452 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004453 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4454 test_asynchat and test_socket_ssl.
4455
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456 It is now possible for multiple instances of the regression test
4457 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004736- Added the future_builtins module, which contains hex() and oct().
4737 These are the PEP 3127 version of these functions, designed to be
4738 compatible with the hex() and oct() builtins from Python 3.0. They
4739 differ slightly in their output formats from the existing, unchanged
4740 Python 2.6 builtins. The expected usage of the future_builtins
4741 module is:
4742 from future_builtins import hex, oct
4743
Eric Smith7ef40bf2008-02-20 23:34:22 +00004744- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4745 exponents for exponents with absolute value < 100. Follows C99
4746 standard. This is a change on Windows, which would use 3 digits.
4747 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4748 so that any alterations it does to the resulting string will be
4749 available in stringlib/formatter.h (for float.__format__).
4750
Eric Smith5a3c1352008-02-19 13:21:56 +00004751- Implemented PEP 3101, Advanced String Formatting. This adds a new
4752 builtin format(); a format() method for str and unicode; a
4753 __format__() method to object, str, unicode, int, long, float, and
4754 datetime; the class string.Formatter; and the C API
4755 PyObject_Format().
4756
Georg Brandl3ee81df2008-05-17 18:14:43 +00004757- Fixed several potential crashes, all caused by specially crafted
4758 __del__ methods exploiting objects in temporarily inconsistent
4759 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004761- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004762 prevent a possible crash: an Abstract Base Class would try to access
4763 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004764

4766 real or imaginary part.

4769 in order to allow pymalloc to free more arenas. Python may give back
4770 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004771
Georg Brandl3ee81df2008-05-17 18:14:43 +00004772- Issue #2045: Fix an infinite recursion triggered when printing a
4773 subclass of collections.defaultdict, if its default_factory is set
4774 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004775
Christian Heimesf75dbef2008-02-08 00:11:31 +00004776- Fixed a minor memory leak in dictobject.c. The content of the free
4777 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00004779- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004780 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004781
Georg Brandl3ee81df2008-05-17 18:14:43 +00004782- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4783 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004784 to compact the internal free lists of pre-allocted ints and floats.
4785
Georg Brandl3ee81df2008-05-17 18:14:43 +00004786- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4787 calls. Python expected the return type int but the fork familie
4788 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004789
Georg Brandl3ee81df2008-05-17 18:14:43 +00004790- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4791 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004792
Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4794 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004795

Georg Brandl3ee81df2008-05-17 18:14:43 +00004799- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4800 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004801
Georg Brandl3ee81df2008-05-17 18:14:43 +00004802- Patch #1473257: generator objects gain a gi_code attribute. This is
4803 the same object as the func_code attribute of the function that
4804 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004805
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Issue #1920: "while 0" statements were completely removed by the
4807 compiler, even in the presence of an "else" clause, which is
4808 supposed to be run when the condition is false. Now the compiler
4809 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004810
Guido van Rossumeead05f2008-01-24 18:21:02 +00004811- A few crashers fixed: weakref_in_del.py (issue #1377858);
4812 loosing_dict_ref.py (issue #1303614, test67.py);
4813 borrowed_ref_[34].py (not in tracker).
4814
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004815- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004816 suppressed while an extension is loaded by calling SetErrorMode in
4817 dynload_win.c. The error is still reported properly.
4818
Georg Brandl3ee81df2008-05-17 18:14:43 +00004819- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004820 several extension methods and modules do not work without unicode
4821 support.
4822
Georg Brandl26543b12008-01-21 18:36:51 +00004823- Issue #1882: when compiling code from a string, encoding cookies in the
4824 second line of code were not always recognized correctly.
4825
Georg Brandl14404b62008-01-19 19:27:05 +00004826- Issue #1679: "0x" was taken as a valid integer literal.
4827
Georg Brandl6caad7d2008-01-26 14:19:22 +00004828- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004829 added.
4830
Christian Heimesc94e2b52008-01-14 04:13:37 +00004831- sys.float_info / PyFloat_GetInfo: The floating point information
4832 object was converted from a dict to a specialized structseq object.
4833
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834- Patch #1816: Added sys.flags structseq. It exposes the status of
4835 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004836
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Objects/structseq.c: Implemented new structseq representation. The
4838 patch makes structseqs (e.g. the return value of os.stat) more
4839 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004840
Georg Brandl3ee81df2008-05-17 18:14:43 +00004841- Patch #1700288: added a type attribute cache that caches method
4842 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004843
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004844- Bug #1776: __import__() no longer accepts filenames on any platform.
4845 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004846
Georg Brandlaed6c662008-01-07 17:25:53 +00004847- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4848
Georg Brandl3ee81df2008-05-17 18:14:43 +00004849- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4850 envvar and sys.dont_write_bytecode attribute. All these can be set
4851 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004852
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- Improve some exception messages when Windows fails to load an
4854 extension module. Now we get for example '%1 is not a valid Win32
4855 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004859- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4860 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004861
Christian Heimes0a8143f2007-12-18 23:22:54 +00004862- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004863 and INF. float("nan"), float("inf") and float("-inf") now work on
4864 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004865
Georg Brandl3ee81df2008-05-17 18:14:43 +00004866- Compiler now generates simpler and faster code for dictionary
4867 literals. The oparg for BUILD_MAP now indicates an estimated
4868 dictionary size. There is a new opcode, STORE_MAP, for adding
4869 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004870
Georg Brandl3ee81df2008-05-17 18:14:43 +00004871- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004879- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004880 SystemError.
4881
Nick Coghlanef01d822007-12-03 12:55:17 +00004882- PEP 366: Allow explicit relative imports when executing modules
4883 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00004898- Patch #1739468: Directories and zipfiles containing a __main__.py
4899 file can now be directly executed by passing their name to the
4900 interpreter. The directory/zipfile is automatically inserted as the
4901 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004902
Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- Issue #1265: Fix a problem with sys.settrace, if the tracing
4904 function uses a generator expression when at the same time the
4905 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004906
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004907- sets and frozensets now have an isdisjoint() method.
4908
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004909- optimize the performance of builtin.sum().
4910
Neal Norwitz44f326e2007-10-05 05:29:17 +00004911- Fix warnings found by the new version of the Coverity checker.
4912
Georg Brandl21e99f42010-03-07 15:23:59 +00004913- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004914 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4915 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004916
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917- Issue #1686386: Tuple's tp_repr did not take into account the
4918 possibility of having a self-referential tuple, which is possible
4919 from C code. Nor did object's tp_str consider that a type's tp_str
4920 could do something that could lead to an inifinite recursion.
4921 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4922 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004923
Georg Brandl3ee81df2008-05-17 18:14:43 +00004924- Issue #1164: It was possible to trigger deadlock when using the
4925 'print' statement to write to a file since the GIL was not released
4926 as needed. Now PyObject_Print() does the right thing along with
4927 various tp_print implementations of the built-in types and those in
4928 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- Issue #1147: Exceptions were directly allowing string exceptions in
4931 their throw() method even though string exceptions no longer
4932 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Issue #1096: Prevent a segfault from getting the repr of a very
4935 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004936
Brett Cannon1e534b52007-09-07 04:18:30 +00004937- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938 PyObject_Call() never calling back out to Python code to trigger
4939 recursion depth updates/checks. Required the creation of a static
4940 RuntimeError instance in case normalizing an exception put the
4941 recursion check value past its limit. Fixes crashers
4942 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004943
Georg Brandl3ee81df2008-05-17 18:14:43 +00004944- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004957- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004958 __*__ attributes. (Some already existed, e.g., __doc__ and
4959 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004960
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004961- Add -3 option to the interpreter to warn about features that are
4962 deprecated and will be changed/removed in Python 3.0.
4963
Georg Brandl2134e752007-05-21 20:34:16 +00004964- Patch #1686487: you can now pass any mapping after '**' in function
4965 calls.
4966
Collin Winter62903052007-05-18 23:11:24 +00004967- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968 "except E as target:". This is to provide forwards compatibility
4969 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004970
Brett Cannon229cee22007-05-05 01:34:02 +00004971- Deprecate BaseException.message as per PEP 352.
4972
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004974 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004976- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004977 setting a plain string, ie don't expand to single letter identifiers.
4978
Raymond Hettinger13936692007-04-11 18:40:58 +00004979- Request #1191699: Slices can now be pickled.
4980
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004981- Request #1193128: str.translate() now allows a None argument for
4982 translations that only remove characters without re-mapping the
4983 remaining characters.
4984
Georg Brandl5cb76c12007-03-21 09:00:39 +00004985- Patch #1682205: a TypeError while unpacking an iterable is no longer
4986 masked by a generic one with the message "unpack non-sequence".
4987
Neal Norwitzaa754b72007-03-21 06:39:48 +00004988- Remove unused file Python/fmod.c.
4989
Guido van Rossum143b5642007-03-23 04:58:42 +00004990- Bug #1683368: The object.__init__() and object.__new__() methods are
4991 now stricter in rejecting excess arguments. The only time when
4992 either allows excess arguments is when it is not overridden and the
4993 other one is. For backwards compatibility, when both are
4994 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004995 warning later). Also, type.__init__() insists on the same signature
4996 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4999 object to complex using its __complex__() method before falling back
5000 to the __float__() method. Therefore, the functions in the cmath
5001 module now can operate on objects that define a __complex__()
5002 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006076 time so that opening a database previously created with the DB_DUP
6077 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6078 opens. Specifically: dictionary assignment to a DB object will
6079 replace all values for a given key when the database allows
6080 duplicate values. DB users should use DB.put(k, v) when they want
6081 to store duplicates; not DB[k] = v.

6088 characters with ASCII value less than 32. Also, it correctly quotes
6089 dots only if they occur on a single line, as opposed to the previous
6090 behavior of quoting dots if they are the second character of any
6091 line.
