1074 32-bit-only installer Pythons on systems with Xcode 4 (currently
1075 OS X 10.8, 10.7, and optionally 10.6).
1076 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1077 * Since Xcode 4 removes ppc support, extension module builds now
1078 check for ppc compiler support and by default remove ppc and
1079 ppc64 archs when they are not available.
1080 * Extension module builds now revert to using system installed
1081 headers and libs (/usr and /System/Library) if the SDK used
1082 to build the interpreter is not installed or has moved.
1083 * Try to avoid building extension modules with deprecated
1084 and problematic Apple llvm-gcc compiler. If original compiler
1085 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001509- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001510 has left two versions of customize_compiler, the original in
1511 distutils.sysconfig and another copy in distutils.ccompiler, with some
1512 parts of distutils calling one and others using the other.

1514 is the case in 3.x.
1515
Ned Deily0d0ea482012-02-10 12:59:06 +01001516- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1517 Distutils-based packages with C extension modules may fail because
1518 Apple has removed gcc-4.2, the version used to build python.org
1519 64-bit/32-bit Pythons. If the user does not explicitly override
1520 the default C compiler by setting the CC environment variable,
1521 Distutils will now attempt to compile extension modules with clang
1522 if gcc-4.2 is required but not found. Also as a convenience, if
1523 the user does explicitly set CC, substitute its value as the default
1524 compiler in the Distutils LDSHARED configuration variable for OS X.
1525 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1526 SDK, neither of which are available in Xcode 4. This change does not
1527 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001777- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1778 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1779 interpreter process. This could cause failures in non-Distutils subprocesses
1780 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001781 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001782 deployment target only in the environment of each build subprocess. It is
1783 still possible to globally override the default by setting
1784 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1785 greater or equal to the default value, the value with which the interpreter
1786 was built.

1816 the ticker doesn't have to wind down to zero from the old starting point
1817 before the new interval takes effect. And if the user increases the
1818 interval, it makes sure the new limit takes effect right away rather have an
1819 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003263- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3264 start byte and the continuation byte(s) are now considered invalid, instead
3265 of the number of bytes specified by the start byte.
3266 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3267 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3268 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3269 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003277- Issue #8748: Fix two issues with comparisons between complex and integer
3278 objects. (1) The comparison could incorrectly return True in some cases
3279 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3280 (2) The comparison raised an OverflowError for large integers, leading
3281 to unpredictable exceptions when combining integers and complex objects
3282 in sets or dicts.

3665 with a non-empty format string. This is an effort to future-proof user
3666 code. If a derived class does not currently implement __format__ but later
3667 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003668 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003669 Python 3.3 and it will be an error in Python 3.4.

3721 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3722 signaling NaNs remain unhashable.

3743 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3744 <=> complex, and complex <=> complex comparisons.

4107 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4108 returning NULL. The macro now returns a statically allocated empty string

4119 strings,
4120 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4121 numeric strings corresponding to subnormal values,
4122 (3) a memory leak for some values large enough to cause overflow, and
4123 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004154- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004155 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004156 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004161- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004162 file position when calling `truncate()`. It would previously change the file
4163 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004164 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4165
Georg Brandlba83f822010-03-14 09:50:54 +00004166- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4167 class used to represent files stored inside an archive. The new
4168 implementation is significantly faster and can be wrapped in a
4169 ``io.BufferedReader`` object for more speedups. It also solves an issue
4170 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4171 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004181- Issue #7748: Since unicode values are supported for some metadata options in

4259-----------------
4260
Georg Brandlba83f822010-03-14 09:50:54 +00004261- The ``__complex__()`` method is now looked up on the class of instances to
4262 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004264- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

4266
Mark Dickinson1b34d252010-01-01 17:27:30 +00004267- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004268 DeprecationWarning when passed a float argument where an integer was expected.
4269 These functions and methods now raise TypeError instead. The majority of the
4270 effects of this change are in the extension modules, but some core functions
4271 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4272 and many unicode/str methods.

4284
Georg Brandlba83f822010-03-14 09:50:54 +00004285- Issue #1811: Improve accuracy and cross-platform consistency for true division
4286 of integers: the result of a/b is now correctly rounded for ints a and b (at
4287 least on IEEE 754 platforms), and in particular does not depend on the
4288 internal representation of a long.

4296
Georg Brandlba83f822010-03-14 09:50:54 +00004297 These executables now work properly with the arch(1) command: ``arch -ppc
4298 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004434- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4435 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004436
Georg Brandlba83f822010-03-14 09:50:54 +00004437- Issue #3382: 'F' formatting for float and complex now convert the result to
4438 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4439 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004440
Georg Brandlba83f822010-03-14 09:50:54 +00004441- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4442 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004443
Georg Brandlba83f822010-03-14 09:50:54 +00004444- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4445 1e-100 used to raise OverflowError, but now gives the requested 120
4446 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004447
Georg Brandlba83f822010-03-14 09:50:54 +00004448- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00004449
Georg Brandlba83f822010-03-14 09:50:54 +00004450- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00004451
Georg Brandlba83f822010-03-14 09:50:54 +00004452- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
4453 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004454
Georg Brandlba83f822010-03-14 09:50:54 +00004455- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4456 decimal string that's guaranteed to round back to x under correct rounding
4457 (with round-half-to-even rounding mode). Previously it gave a string based on
4458 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4459 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4460 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004461
Georg Brandlba83f822010-03-14 09:50:54 +00004462- Issue #7117: On almost all platforms: float-to-string and string-to-float
4463 conversions within Python are now correctly rounded. Places these conversions
4464 occur include: str for floats and complex numbers; the float and complex
4465 constructors; old-style and new-style numeric formatting; serialization and
4466 deserialization of floats and complex numbers using marshal, pickle and json;
4467 parsing of float and imaginary literals in Python code; Decimal-to-float
4468 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004469
Georg Brandlba83f822010-03-14 09:50:54 +00004470 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4471 providing correctly-rounded strtod and dtoa C functions. This code is
4472 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4473 the C compiler. There may be a small number of platforms on which correct
4474 operation of this code cannot be guaranteed, so the code is not used: notably,
4475 this applies to platforms where the C double format is not IEEE 754 binary64,
4476 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4477 and Python's configure script is unable to determine how to change the FPU
4478 precision. On these platforms conversions use the platform strtod and dtoa,
4479 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004480
Georg Brandlba83f822010-03-14 09:50:54 +00004481- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4482 uses the correctly-rounded string <-> float conversions described above (when
4483 available), and so produces correctly rounded results that will display nicely
4484 under the float repr. There are two related small changes: (1) round now
4485 accepts any class with an ``__index__()`` method for its second argument (but
4486 no longer accepts floats for the second argument), and (2) an excessively
4487 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4488 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00004489
Philip Jenveyfab8be22009-11-17 02:42:26 +00004490- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
4491
Georg Brandlba83f822010-03-14 09:50:54 +00004492- Fix several issues with ``compile()``. The input can now contain Windows and
4493 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00004494
Georg Brandlba83f822010-03-14 09:50:54 +00004495- Remove length limitation when constructing a complex number from a unicode
4496 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00004497
Georg Brandlba83f822010-03-14 09:50:54 +00004498- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
4499 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +00004500

4502
Georg Brandlba83f822010-03-14 09:50:54 +00004503- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
4504 which fixes the problem of some exceptions being thrown at shutdown when the
4505 interpreter is killed. Patch by Adam Olsen.

4514 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00004515
Georg Brandlba83f822010-03-14 09:50:54 +00004516- Issue #1754094: Improve the stack depth calculation in the compiler. There
4517 should be no other effect than a small decrease in memory use. Patch by
4518 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00004519
Georg Brandlba83f822010-03-14 09:50:54 +00004520- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
4521 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00004522
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00004523- Issue #1571184: The Unicode database contains properties for more characters.
4524 The tables for code points representing numeric values, white spaces or line
4525 breaks are now generated from the official Unicode Character Database files,
4526 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00004635- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4636 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4637 but with at least one decimal point and with a default precision
4638 of 12. Previously, the behavior the same but with a default precision of 6.
4639 This more closely matches ``str()``, and reduces surprises when adding
4640 alignment flags to the empty presentation type. This also affects the new
4641 complex.__format__ in the same way.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004893- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4894 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4902 allocator will be automatically disabled when running under Valgrind. This
4903 gives improved memory leak detection when running under Valgrind, while taking
4904 advantage of pymalloc at other times.

6277 ``printf`` function, whereas PyString_FromFormat has an independent
6278 implementation and uses "%zd" on all platforms for size_t values.
6279 This makes a difference on win64, where ``printf`` needs "%Id" to display
6280 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006282- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6283 error.
6284
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006285- Issue #3777: long() applied to a float object now always return a long
6286 object; previously an int would be returned for small values. the __long__
6287 method is allowed to return either an int or a long, but the behaviour of
6288 float objects should not change to respect backward compatibility.
6289
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006290- Issue #3751: str.rpartition would perform a left-partition when called with
6291 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006295- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006296 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006297 was correctly parsed but parsing of subsequent arguments failed.
6298
Vinay Sajip35e3b032008-09-01 14:33:59 +00006299- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006300 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6301 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6302 when given a tuple of classes as second argument, were looking up
6303 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6304 type object.
6305
Neal Norwitz18aa3882008-08-24 05:04:52 +00006306- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006375 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6376 for catch_warnings() also led to an improvement in the raising of a
6377 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006443What's New in Python 2.6 beta 3?
6444================================
6445
Barry Warsaw07a4a382008-08-21 01:15:08 +00006446*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006447
6448Core and Builtins
6449-----------------
6450
Guido van Rossumf8402962008-08-20 15:01:50 +00006451- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6452 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6453 extensions do not automatically benefit from the class attribute
6454 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6455 to their tp_flags field if they care. This is a backwards
6456 compatibility feature; in 3.0, all types will use the cache by
6457 default.
6458
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006459- Keyword arguments can now follow starred arguments. (``f(a, *args,
6460 keyword=23)`` is now valid syntax.)
6461
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006462- ctypes function pointers that are COM methods have a boolean True
6463 value again.
6464
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006465- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6466 by denying s# to parse objects that have a releasebuffer procedure,
6467 and introducing s*.
6468
Georg Brandl1e13ea92008-08-11 09:07:59 +00006469- Issue #3537: Fix an assertion failure when an empty but presized dict
6470 object was stored in the freelist.
6471
Mark Dickinsonb6467572008-08-04 21:30:09 +00006472- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6473 ValueError consistently across platforms.
6474
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006475- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6476 (64bit Unix, for example), unichr() would truncate its argument and return
6477 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6478
Neal Norwitze7d8be82008-07-31 17:17:14 +00006479- Apply security patches from Apple.
6480
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006481- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6482 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6483
Antoine Pitrou92f82162008-07-25 22:22:08 +00006484- Issue #1819: function calls with several named parameters are now on
6485 average 35% faster (as measured by pybench).
6486
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006487- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6488 the python debugger steps into a class statement: the free variables (local
6489 variables defined in an outer scope) would be deleted from the outer scope.
6490
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006491- Issue #2620: Overflow checking when allocating or reallocating memory
6492 was not always being done properly in some python types and extension
6493 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6494 all been updated to perform better checks and places in the code that
6495 would previously leak memory on the error path when such an allocation
6496 failed have been fixed.

6500
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006501- Issue #3612: Added some missing basic types in ctypes.wintypes.
6502
Benjamin Petersone977ad42008-08-20 01:42:01 +00006503- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6504 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6505
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006506- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6507 version reported by these tools does not necessarily follow the python
6508 version numbering scheme, so the module is less strict when parsing it.
6509
Nick Coghlanf70385a2008-08-18 12:42:46 +00006510- Issue #2235: Added Py3k warnings for types which will become unhashable
6511 under the stricter __hash__ inheritance rules in 3.0. Several types
6512 which did not meet the rules for hash invariants and were already
6513 unhashable in 3.0 have now been explicitly flagged as unhashable in
6514 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6515 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6516
Brett Cannon88f801d2008-08-18 00:46:22 +00006517- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6518 imported into the module but exposed as part of the module's API.
6519
Brett Cannon7b96f072008-08-18 00:41:11 +00006520- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6521
Brett Cannon46225e72008-08-18 00:36:52 +00006522- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006524- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6525
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006526- Issue #3575: Incremental decoder's decode function now takes bytearray
6527 by using 's*' instead of 't#'.
6528
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006529- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006530 fails unicode conversion on 2nd parameter. (windows only)
6531
Georg Brandl222e2082010-08-01 22:27:39 +00006532- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006533 in a redirect.
6534

Brett Cannon721b1452008-08-16 22:00:27 +00006536 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006537
Facundo Batistaeb90b782008-08-16 14:44:07 +00006538- Issue #2776: fixed small issue when handling an URL with double slash
6539 after a 302 response in the case of not going through a proxy.
6540
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006541- Issue #2676: in the email package, content-type parsing was hanging on
6542 pathological input because of quadratic or exponential behaviour of a
6543 regular expression.
6544
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006545- Issue #3476: binary buffered reading through the new "io" library is now
6546 thread-safe.
6547
Brett Cannonbf3157b2008-08-14 05:00:03 +00006548- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6549 since mimetools itself is deprecated. Because modules are cached, all
6550 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6551
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006552- Issue #3134: shutil referenced undefined WindowsError symbol.
6553
Robert Schuppenies14646332008-08-10 11:01:53 +00006554- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6555 menu entries were not deleted.
6556
Brett Cannon83e81842008-08-09 23:30:55 +00006557- Copied the implementation of reduce() to _functools.reduce() to have a
6558 version that did not raise a DeprecationWarning under -3.
6559
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006560- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6561 a MemoryError rather than silently stop the iteration.

Guido van Rossum59ce9012008-08-09 14:55:34 +00006563- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6564 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00006586 asking for a specific length. This problem only affected files opened

6630
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006631- Issue #643841: The language reference now provides more detailed

6643-----------------
6644
Georg Brandl3e483f62008-07-16 22:57:41 +00006645- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6646 its methods now allow for items objects that can be converted to
6647 an integer using operator.index().
6648
Mark Dickinson64b7e502008-07-16 09:40:03 +00006649- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6650 produced a ValueError instead of giving the correct float.
6651
Eric Smitha5fa5a22008-07-16 00:11:49 +00006652- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6653 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6654
Mark Dickinson7103aa42008-07-15 19:08:33 +00006655- Issue #3008: the float type has a new instance method 'float.hex'
6656 and a new class method 'float.fromhex' to convert floating-point
6657 numbers to and from hexadecimal strings, respectively.
6658
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006659- Issue #2235: __hash__ is once again inherited by default. To allow
6660 collections.Hashable to remain meaningful in the presence of the
6661 default hash implementation (object.__hash__), it is now possible
6662 to explicit block inheritance of hash by setting __hash__=None at
6663 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6664 level.
6665
Nick Coghlanb028f502008-07-13 14:52:36 +00006666- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6667 the parent module cannot be found while performing an absolute import.
6668 This means that an incorrectly defined __package__ attribute will
6669 now only prevent relative imports in that module rather than causing
6670 all imports from that module to fail.
6671
Nick Coghlan14ff9942008-07-08 14:21:42 +00006672- Issue #2517: Allow unicode messages in Exceptions again by correctly

6682 another thread's dictionary.
6683
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006684- Issue #3004: Minor change to slice.indices(): the start and stop
6685 arguments are now treated identically, making the behaviour easier
6686 to describe and understand. For example, slice(None, -10,
6687 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6688 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6689 10, -1).
6690
Georg Brandl278fc502008-07-19 12:46:12 +00006691- Issue #3219: Calling a function with repeated keyword arguments,
6692 f(a=2, a=23), would not cause a syntax error. This was a regression
6693 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006731- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6732 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006733 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006734 content-length. The problem had been corrected in the 2.4 branch, but never
6735 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006750- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7138
Brett Cannonb61d8012008-05-11 23:39:04 +00007139- ``Lib/lib-old`` is now added to sys.path.
7140
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007141- On MacOS X it is now possible to install the framework in 64-bit
7142 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007143 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007144
7145 This is controlled by the configure argument ``--with-universal-archs``:
7146
7147 - ``--with-universal-archs=all``: install 4-way universal
7148
7149 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7150
7151 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7152
7153 This option should be used in combination with ``--enable-universalsdk=``.
7154
7155 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00007164
7165- The PyString functions have been renamed to PyBytes. A batch of
7166 defines were added so that the linker still sees the original
7167 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007205- Issue #1631171: Re-implement the 'warnings' module in C (the
7206 original Python code has been kept as backup). This will allow for
7207 using the 'warning's machinery in such places as the parser where
7208 use of pure Python code is not possible. Both the ``showarning()``
7209 and ``formatwarning()`` gain an optional 'line' argument which is
7210 not called by default for backwards-compatibility reasons. Setting
7211 ``warnings.showwarning()`` to an implementation that lacks support
7212 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007237- The getpass module has been improved on Unix. It now uses /dev/tty
7238 by default and uses stderr instead of stdout. A GetPassWarning is
7239 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007254- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007255 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007275- Issue #2550: The approach used by client/server code for obtaining
7276 ports to listen on in network-oriented tests has been refined in an
7277 effort to facilitate running multiple instances of the entire
7278 regression test suite in parallel without issue.
7279 test_support.bind_port() has been fixed such that it will always
7280 return a unique port -- which wasn't always the case with the
7281 previous implementation, especially if socket options had been set
7282 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7283 new implementation of bind_port() will actually raise an exception
7284 if it is passed an AF_INET/SOCK_STREAM socket with either the
7285 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7286 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7287 the socket it's been passed. This currently only applies to
7288 Windows. This option prevents any other sockets from binding to the
7289 host/port we've bound to, thus removing the possibility of the
7290 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7291 when a second SOCK_STREAM socket binds and accepts to a host/port
7292 that's already been bound by another socket. The optional preferred
7293 port parameter to bind_port() has been removed. Under no
7294 circumstances should tests be hard coding ports!
7295
7296 test_support.find_unused_port() has also been introduced, which will
7297 pass a temporary socket object to bind_port() in order to obtain an
7298 unused port. The temporary socket object is then closed and
7299 deleted, and the port is returned. This method should only be used
7300 for obtaining an unused port in order to pass to an external program
7301 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7302 a parameter to a server-oriented class that doesn't give you direct
7303 access to the underlying socket used.
7304
7305 Finally, test_support.HOST has been introduced, which should be used
7306 for the host argument of any relevant socket calls (i.e. bind and
7307 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007308
7309 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007310 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007311 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7312 test_asynchat and test_socket_ssl.
7313
Georg Brandl3ee81df2008-05-17 18:14:43 +00007314 It is now possible for multiple instances of the regression test
7315 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007594- Added the future_builtins module, which contains hex() and oct().
7595 These are the PEP 3127 version of these functions, designed to be
7596 compatible with the hex() and oct() builtins from Python 3.0. They
7597 differ slightly in their output formats from the existing, unchanged
7598 Python 2.6 builtins. The expected usage of the future_builtins
7599 module is:
7600 from future_builtins import hex, oct
7601
Eric Smith7ef40bf2008-02-20 23:34:22 +00007602- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7603 exponents for exponents with absolute value < 100. Follows C99
7604 standard. This is a change on Windows, which would use 3 digits.
7605 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7606 so that any alterations it does to the resulting string will be
7607 available in stringlib/formatter.h (for float.__format__).
7608
Eric Smith5a3c1352008-02-19 13:21:56 +00007609- Implemented PEP 3101, Advanced String Formatting. This adds a new
7610 builtin format(); a format() method for str and unicode; a
7611 __format__() method to object, str, unicode, int, long, float, and
7612 datetime; the class string.Formatter; and the C API
7613 PyObject_Format().
7614
Georg Brandl3ee81df2008-05-17 18:14:43 +00007615- Fixed several potential crashes, all caused by specially crafted
7616 __del__ methods exploiting objects in temporarily inconsistent
7617 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007619- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007620 prevent a possible crash: an Abstract Base Class would try to access
7621 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007626- Clear all free lists during a gc.collect() of the highest generation
7627 in order to allow pymalloc to free more arenas. Python may give back
7628 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007629
Georg Brandl3ee81df2008-05-17 18:14:43 +00007630- Issue #2045: Fix an infinite recursion triggered when printing a
7631 subclass of collections.defaultdict, if its default_factory is set
7632 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007633
Christian Heimesf75dbef2008-02-08 00:11:31 +00007634- Fixed a minor memory leak in dictobject.c. The content of the free
7635 list was not freed on interpreter shutdown.
7636
Georg Brandl21e99f42010-03-07 15:23:59 +00007637- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00007639
Georg Brandl3ee81df2008-05-17 18:14:43 +00007640- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7641 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007642 to compact the internal free lists of pre-allocted ints and floats.
7643
Georg Brandl3ee81df2008-05-17 18:14:43 +00007644- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7645 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00007657- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7658 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007659
Georg Brandl3ee81df2008-05-17 18:14:43 +00007660- Patch #1473257: generator objects gain a gi_code attribute. This is
7661 the same object as the func_code attribute of the function that
7662 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007663
Georg Brandl3ee81df2008-05-17 18:14:43 +00007664- Issue #1920: "while 0" statements were completely removed by the
7665 compiler, even in the presence of an "else" clause, which is
7666 supposed to be run when the condition is false. Now the compiler
7667 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007668
Guido van Rossumeead05f2008-01-24 18:21:02 +00007669- A few crashers fixed: weakref_in_del.py (issue #1377858);
7670 loosing_dict_ref.py (issue #1303614, test67.py);
7671 borrowed_ref_[34].py (not in tracker).
7672
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007673- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007674 suppressed while an extension is loaded by calling SetErrorMode in
7675 dynload_win.c. The error is still reported properly.
7676
Georg Brandl3ee81df2008-05-17 18:14:43 +00007677- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007678 several extension methods and modules do not work without unicode
7679 support.
7680
Georg Brandl26543b12008-01-21 18:36:51 +00007681- Issue #1882: when compiling code from a string, encoding cookies in the
7682 second line of code were not always recognized correctly.
7683
Georg Brandl14404b62008-01-19 19:27:05 +00007684- Issue #1679: "0x" was taken as a valid integer literal.
7685
Georg Brandl6caad7d2008-01-26 14:19:22 +00007686- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007687 added.
7688
Christian Heimesc94e2b52008-01-14 04:13:37 +00007689- sys.float_info / PyFloat_GetInfo: The floating point information
7690 object was converted from a dict to a specialized structseq object.
7691
Georg Brandl3ee81df2008-05-17 18:14:43 +00007692- Patch #1816: Added sys.flags structseq. It exposes the status of
7693 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007694
Georg Brandl3ee81df2008-05-17 18:14:43 +00007695- Objects/structseq.c: Implemented new structseq representation. The
7696 patch makes structseqs (e.g. the return value of os.stat) more
7697 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007698
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699- Patch #1700288: added a type attribute cache that caches method
7700 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007701
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007702- Bug #1776: __import__() no longer accepts filenames on any platform.
7703 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007704
Georg Brandlaed6c662008-01-07 17:25:53 +00007705- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7708 envvar and sys.dont_write_bytecode attribute. All these can be set
7709 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007710
Georg Brandl3ee81df2008-05-17 18:14:43 +00007711- Improve some exception messages when Windows fails to load an
7712 extension module. Now we get for example '%1 is not a valid Win32
7713 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007714

Christian Heimes0a8143f2007-12-18 23:22:54 +00007720- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007721 and INF. float("nan"), float("inf") and float("-inf") now work on
7722 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007723
Georg Brandl3ee81df2008-05-17 18:14:43 +00007724- Compiler now generates simpler and faster code for dictionary
7725 literals. The oparg for BUILD_MAP now indicates an estimated
7726 dictionary size. There is a new opcode, STORE_MAP, for adding
7727 entries to the dictionary.

7739
Nick Coghlanef01d822007-12-03 12:55:17 +00007740- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00007756- Patch #1739468: Directories and zipfiles containing a __main__.py
7757 file can now be directly executed by passing their name to the
7758 interpreter. The directory/zipfile is automatically inserted as the
7759 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007760
Georg Brandl3ee81df2008-05-17 18:14:43 +00007761- Issue #1265: Fix a problem with sys.settrace, if the tracing
7762 function uses a generator expression when at the same time the
7763 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007764
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007765- sets and frozensets now have an isdisjoint() method.
7766
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007767- optimize the performance of builtin.sum().
7768
Neal Norwitz44f326e2007-10-05 05:29:17 +00007769- Fix warnings found by the new version of the Coverity checker.
7770
Georg Brandl21e99f42010-03-07 15:23:59 +00007771- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007772 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7773 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007774
Georg Brandl3ee81df2008-05-17 18:14:43 +00007775- Issue #1686386: Tuple's tp_repr did not take into account the
7776 possibility of having a self-referential tuple, which is possible
7777 from C code. Nor did object's tp_str consider that a type's tp_str
7778 could do something that could lead to an inifinite recursion.
7779 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7780 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007781
Georg Brandl3ee81df2008-05-17 18:14:43 +00007782- Issue #1164: It was possible to trigger deadlock when using the
7783 'print' statement to write to a file since the GIL was not released
7784 as needed. Now PyObject_Print() does the right thing along with
7785 various tp_print implementations of the built-in types and those in
7786 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007787
Georg Brandl3ee81df2008-05-17 18:14:43 +00007788- Issue #1147: Exceptions were directly allowing string exceptions in
7789 their throw() method even though string exceptions no longer
7790 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007791
Georg Brandl3ee81df2008-05-17 18:14:43 +00007792- Issue #1096: Prevent a segfault from getting the repr of a very
7793 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007794
Brett Cannon1e534b52007-09-07 04:18:30 +00007795- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007796 PyObject_Call() never calling back out to Python code to trigger
7797 recursion depth updates/checks. Required the creation of a static
7798 RuntimeError instance in case normalizing an exception put the
7799 recursion check value past its limit. Fixes crashers
7800 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007801
Georg Brandl3ee81df2008-05-17 18:14:43 +00007802- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007815- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816 __*__ attributes. (Some already existed, e.g., __doc__ and
7817 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007818
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007819- Add -3 option to the interpreter to warn about features that are
7820 deprecated and will be changed/removed in Python 3.0.
7821
Georg Brandl2134e752007-05-21 20:34:16 +00007822- Patch #1686487: you can now pass any mapping after '**' in function
7823 calls.
7824
Collin Winter62903052007-05-18 23:11:24 +00007825- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007826 "except E as target:". This is to provide forwards compatibility
7827 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007828
Brett Cannon229cee22007-05-05 01:34:02 +00007829- Deprecate BaseException.message as per PEP 352.
7830
Georg Brandl3ee81df2008-05-17 18:14:43 +00007831- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007832 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007833
Vinay Sajip8549ce32007-05-06 17:53:37 +00007834- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007835 setting a plain string, ie don't expand to single letter identifiers.
7836
Raymond Hettinger13936692007-04-11 18:40:58 +00007837- Request #1191699: Slices can now be pickled.
7838
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007839- Request #1193128: str.translate() now allows a None argument for
7840 translations that only remove characters without re-mapping the
7841 remaining characters.
7842
Georg Brandl5cb76c12007-03-21 09:00:39 +00007843- Patch #1682205: a TypeError while unpacking an iterable is no longer
7844 masked by a generic one with the message "unpack non-sequence".
7845
Neal Norwitzaa754b72007-03-21 06:39:48 +00007846- Remove unused file Python/fmod.c.
7847
Guido van Rossum143b5642007-03-23 04:58:42 +00007848- Bug #1683368: The object.__init__() and object.__new__() methods are
7849 now stricter in rejecting excess arguments. The only time when
7850 either allows excess arguments is when it is not overridden and the
7851 other one is. For backwards compatibility, when both are
7852 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007853 warning later). Also, type.__init__() insists on the same signature
7854 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007855
Georg Brandl3ee81df2008-05-17 18:14:43 +00007856- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7857 object to complex using its __complex__() method before falling back
7858 to the __float__() method. Therefore, the functions in the cmath
7859 module now can operate on objects that define a __complex__()
7860 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007861
Georg Brandl3ee81df2008-05-17 18:14:43 +00007862- Patch #1623563: allow __class__ assignment for classes with
7863 __slots__. The old and the new class are still required to have the
7864 same slot names.

7870 ``object.__reduce_ex__()`` is called with an object that is faking
7871 its type.

7877
Georg Brandl7b9c5552007-03-12 14:30:05 +00007878- Bug #1678647: write a newline after printing an exception in any
7879 case, even when converting the value to a string failed.
7880
Georg Brandl871f1bc2007-03-12 13:17:36 +00007881- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007882 its argument, if it exists. If not, it will work like before. This
7883 allows customizing the output of dir() in the presence of a
7884 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00007999- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008017 generator expressions (x for x, in ... ) works again. Fixing this
8018 problem required changing the .pyc magic number. This means that

Facundo Batistad918a652007-04-24 13:54:38 +00008407- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008408 the client's request was successfully received, understood, and

8422
Vinay Sajip8549ce32007-05-06 17:53:37 +00008423- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00008449 AttributeError instead of an IOError when the server's response
8450 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008484 are set for invalid interpolation sequences that would lead to
8485 errors on reading back those values.

8541 TestCase and TestSuite subclasses (not instances) are no longer
8542 accepted in TestSuite.addTest(). This should cause no

8544 -- the failure just occurred later, with a more cumbersome
8545 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008928 time so that opening a database previously created with the DB_DUP
8929 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8930 opens. Specifically: dictionary assignment to a DB object will
8931 replace all values for a given key when the database allows
8932 duplicate values. DB users should use DB.put(k, v) when they want
8933 to store duplicates; not DB[k] = v.

8940 characters with ASCII value less than 32. Also, it correctly quotes
8941 dots only if they occur on a single line, as opposed to the previous
8942 behavior of quoting dots if they are the second character of any
8943 line.
