Antoine Pitrou0a7b65b2010-09-08 12:40:49 +0000644- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
645 thread-local storage key.
646
Victor Stinnercaafd772010-09-08 10:51:01 +0000647- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
648 encoding and errors attributes instead of using utf-8 in strict mode, to get
649 the same behaviour than the print statement.
650
Antoine Pitrou9cf85f12010-09-01 21:17:34 +0000651- Issue #9737: Fix a crash when trying to delete a slice or an item from

664 output with no type specifier failed to match the str output:
665

782 by Andrew Bennetts.

791
Raymond Hettinger20397532010-09-12 02:11:45 +0000792- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
793 This prevents user-created self-referencing ordered dictionaries from
794 becoming permanently uncollectable GC garbage. The downside is that
795 removing __del__ means that the internal doubly-linked list has to wait for
796 GC collection rather than freeing memory immediately when the refcnt drops
797 to zero.
798
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000799- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

802
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000803- Issue #9792: In case of connection failure, socket.create_connection()
804 would swallow the exception and raise a new one, making it impossible
805 to fetch the original errno, or to filter timeout errors. Now the
806 original error is re-raised.
807
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000808- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
809 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
810 be updated back after the system call. Original patch by Brian Brazil.
811
Antoine Pitroudca9de92010-09-04 17:52:26 +0000812- Issue #1100562: Fix deep-copying of objects derived from the list and
813 dict types. Patch by Michele Orrù and Björn Lindqvist.

816 ConfigParser.write.
817
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000818- Issue #808164: Fixed socket.close to avoid references to globals, to
819 avoid issues when socket.close is called from a __del__ method.
820
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000821- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

827
R. David Murray7c4bf552010-08-25 01:45:57 +0000828- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
829 character years even if the message contains RFC822 two character years.
830
Daniel Stutzbach91287322010-08-24 21:09:30 +0000831- Issue #8750: Fixed MutableSet's methods to correctly handle

833
Victor Stinnercaafd772010-09-08 10:51:01 +0000834- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

847
Benjamin Peterson52c36052010-08-21 03:03:22 +0000848- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
849 are not held onto after they are deleted elsewhere.
850
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000851- Issue #9626: the view methods for collections.OrderedDict() were returning
852 the unordered versions inherited from dict. Those methods are now
853 overridden to provide ordered views.
854
Éric Araujo0389ae62010-08-14 03:07:46 +0000855- Issue #8688: MANIFEST files created by distutils now include a magic
856 comment indicating they are generated. Manually maintained MANIFESTs
857 without this marker will not be overwritten or removed.
858
Antoine Pitroue1436d12010-08-12 15:25:51 +0000859- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

866 patch by Jason V. Miller.

1255
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001256- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1257 start byte and the continuation byte(s) are now considered invalid, instead
1258 of the number of bytes specified by the start byte.
1259 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1260 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1261 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1262 Previous versions returned a single u'\ufffd'.

1266 arises from the "Overriding __eq__ blocks inheritance ..." warning
1267 when turned into an exception: in this case the exception simply
1268 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001270- Issue #8748: Fix two issues with comparisons between complex and integer
1271 objects. (1) The comparison could incorrectly return True in some cases
1272 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1273 (2) The comparison raised an OverflowError for large integers, leading
1274 to unpredictable exceptions when combining integers and complex objects
1275 in sets or dicts.
1276
Mark Dickinson81336372010-05-30 12:12:25 +00001277- Issue #5211: Implicit coercion for the complex type is now completely
1278 removed. (Coercion for arithmetic operations was already removed in 2.7
1279 alpha 4, but coercion for rich comparisons was accidentally left in.)
1280
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001281- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00001468- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1469 operation raises multiple signals and more than one of those signals is
1470 trapped, the specification determines the order in which the signals should be
1471 handled. In many cases this order wasn't being followed, leading to the wrong
1472 Python exception being raised.

1658 with a non-empty format string. This is an effort to future-proof user
1659 code. If a derived class does not currently implement __format__ but later
1660 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001661 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001662 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001695- Issue #8257: The Decimal construct now accepts a float instance directly,
1696 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001697
1698 >>> Decimal(1.1)
1699 Decimal('1.100000000000000088817841970012523233890533447265625')
1700

Georg Brandlfee0f442010-05-22 21:26:21 +00001712- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1713 InvalidOperation instead of returning False. (Comparisons involving a quiet
1714 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1715 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001717- Issue #2531: Comparison operations between floats and Decimal instances now
1718 return a result based on the numeric values of the operands; previously they
1719 returned an arbitrary result based on the relative ordering of id(float) and
1720 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001722- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001723 argument `-` which tells it to read files to compile from stdin. Each line is
1724 read on demand and the named file is compiled immediately. (Original patch by
1725 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001734- Comparisons using one of <, <=, >, >= between a complex instance and a
1735 Fractions instance now raise TypeError instead of returning True/False. This
1736 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1737 <=> complex, and complex <=> complex comparisons.

1837 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00001841- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1842 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001844 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1845 inconsistent: __int__ was used for some integer codes but not for others, and
1846 the set of integer codes for which it was used differed between native packing
1847 and standard packing.)

2160 class used to represent files stored inside an archive. The new
2161 implementation is significantly faster and can be wrapped in a
2162 ``io.BufferedReader`` object for more speedups. It also solves an issue
2163 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2176 encoded string for them. This ensures that the upload and register commands
2177 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00002260- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002261 DeprecationWarning when passed a float argument where an integer was expected.
2262 These functions and methods now raise TypeError instead. The majority of the
2263 effects of this change are in the extension modules, but some core functions
2264 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2265 and many unicode/str methods.

2431 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2432 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002433
Georg Brandlba83f822010-03-14 09:50:54 +00002434- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2435 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00002437- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2438 1e-100 used to raise OverflowError, but now gives the requested 120
2439 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002448- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2449 decimal string that's guaranteed to round back to x under correct rounding
2450 (with round-half-to-even rounding mode). Previously it gave a string based on
2451 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2452 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2453 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002454
Georg Brandlba83f822010-03-14 09:50:54 +00002455- Issue #7117: On almost all platforms: float-to-string and string-to-float
2456 conversions within Python are now correctly rounded. Places these conversions
2457 occur include: str for floats and complex numbers; the float and complex
2458 constructors; old-style and new-style numeric formatting; serialization and
2459 deserialization of floats and complex numbers using marshal, pickle and json;
2460 parsing of float and imaginary literals in Python code; Decimal-to-float
2461 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002462
Georg Brandlba83f822010-03-14 09:50:54 +00002463 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2464 providing correctly-rounded strtod and dtoa C functions. This code is
2465 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2466 the C compiler. There may be a small number of platforms on which correct
2467 operation of this code cannot be guaranteed, so the code is not used: notably,
2468 this applies to platforms where the C double format is not IEEE 754 binary64,
2469 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2470 and Python's configure script is unable to determine how to change the FPU
2471 precision. On these platforms conversions use the platform strtod and dtoa,
2472 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002474- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2475 uses the correctly-rounded string <-> float conversions described above (when
2476 available), and so produces correctly rounded results that will display nicely
2477 under the float repr. There are two related small changes: (1) round now
2478 accepts any class with an ``__index__()`` method for its second argument (but
2479 no longer accepts floats for the second argument), and (2) an excessively
2480 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2481 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002628- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2629 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2630 but with at least one decimal point and with a default precision
2631 of 12. Previously, the behavior the same but with a default precision of 6.
2632 This more closely matches ``str()``, and reduces surprises when adding
2633 alignment flags to the empty presentation type. This also affects the new
2634 complex.__format__ in the same way.

4260-----------------
4261
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004262- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4263
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004264- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4265 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4266 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4267 ``printf`` function, whereas PyString_FromFormat has an independent
4268 implementation and uses "%zd" on all platforms for size_t values.
4269 This makes a difference on win64, where ``printf`` needs "%Id" to display
4270 64bit values.
4271
Benjamin Peterson97179b02008-09-09 20:55:01 +00004272- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4273 error.
4274
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004275- Issue #3777: long() applied to a float object now always return a long
4276 object; previously an int would be returned for small values. the __long__
4277 method is allowed to return either an int or a long, but the behaviour of
4278 float objects should not change to respect backward compatibility.
4279
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004280- Issue #3751: str.rpartition would perform a left-partition when called with
4281 a unicode argument.
4282
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004283- Issue #3683: Fix compilation when --without-threads is given.
4284
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004285- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004286 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004287 was correctly parsed but parsing of subsequent arguments failed.
4288
Vinay Sajip35e3b032008-09-01 14:33:59 +00004289- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004290 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4291 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4292 when given a tuple of classes as second argument, were looking up
4293 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4294 type object.
4295
Neal Norwitz18aa3882008-08-24 05:04:52 +00004296- Fix crashes on memory allocation failure found with failmalloc.
4297
4298- Fix memory leaks found with valgrind and update suppressions file.
4299
4300- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4301
4302- Fix problem using wrong name in decimal module reported by pychecker.
4303
Christian Heimes7d4c3172008-08-22 19:47:25 +00004304- Silenced another compiler warning about a used but not defined
4305 function 'stringlib_contains_obj'.
4306
Benjamin Peterson712ee922008-08-24 18:10:20 +00004307- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4308 ``__delslice__``.
4309
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004310- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4311 library targets in the Makefile.
4312
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004313- Issue #1204: The configure script now tests for additional libraries
4314 that may be required when linking against readline. This fixes issues
4315 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
4316
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00004317C-API

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00004325- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
4326 stack usage in the case of deeply nested objects.
4327

Nick Coghland2e09382008-09-11 12:11:06 +00004338- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004339 return a list or None rather than a custom object.
4340
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004341- Issue #1638033: Cookie.Morsel gained the httponly attribute.
4342
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00004343- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004365 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4366 for catch_warnings() also led to an improvement in the raising of a
4367 DeprecationWarning related to warnings.warn_explicit().
4368
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004369- The deprecation warnings for the old camelCase threading API were removed.

4391
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004392- Issue #2975: When compiling several extension modules with Visual Studio 2008
4393 from the same python interpreter, some environment variables would grow
4394 without limit.
4395
Benjamin Peterson37346b22008-08-23 20:27:43 +00004396- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4397 exploitation of poor argument checking.
4398
Gerhard Häringef2276b2008-09-12 13:54:06 +00004399- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

4412 wrapper for warnings.catch_warnings() that makes it easier to check
4413 that expected warning messages are being reported.
4414
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004415- Issue #3796: Some tests functions were not enabled in test_float.

Barry Warsaw07a4a382008-08-21 01:15:08 +00004436*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004437
4438Core and Builtins
4439-----------------
4440
Guido van Rossumf8402962008-08-20 15:01:50 +00004441- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4442 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4443 extensions do not automatically benefit from the class attribute
4444 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4445 to their tp_flags field if they care. This is a backwards
4446 compatibility feature; in 3.0, all types will use the cache by
4447 default.
4448
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004449- Keyword arguments can now follow starred arguments. (``f(a, *args,
4450 keyword=23)`` is now valid syntax.)
4451
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004452- ctypes function pointers that are COM methods have a boolean True
4453 value again.
4454
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004455- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4456 by denying s# to parse objects that have a releasebuffer procedure,
4457 and introducing s*.
4458
Georg Brandl1e13ea92008-08-11 09:07:59 +00004459- Issue #3537: Fix an assertion failure when an empty but presized dict
4460 object was stored in the freelist.
4461
Mark Dickinsonb6467572008-08-04 21:30:09 +00004462- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4463 ValueError consistently across platforms.
4464
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004465- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4466 (64bit Unix, for example), unichr() would truncate its argument and return
4467 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4468
Neal Norwitze7d8be82008-07-31 17:17:14 +00004469- Apply security patches from Apple.
4470
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004471- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4472 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4473
Antoine Pitrou92f82162008-07-25 22:22:08 +00004474- Issue #1819: function calls with several named parameters are now on
4475 average 35% faster (as measured by pybench).
4476
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004477- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4478 the python debugger steps into a class statement: the free variables (local
4479 variables defined in an outer scope) would be deleted from the outer scope.
4480
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004481- Issue #2620: Overflow checking when allocating or reallocating memory
4482 was not always being done properly in some python types and extension
4483 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4484 all been updated to perform better checks and places in the code that
4485 would previously leak memory on the error path when such an allocation
4486 failed have been fixed.

4489-------
4490
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004491- Issue #3612: Added some missing basic types in ctypes.wintypes.
4492
Benjamin Petersone977ad42008-08-20 01:42:01 +00004493- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4494 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4495
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004496- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4497 version reported by these tools does not necessarily follow the python
4498 version numbering scheme, so the module is less strict when parsing it.
4499
Nick Coghlanf70385a2008-08-18 12:42:46 +00004500- Issue #2235: Added Py3k warnings for types which will become unhashable
4501 under the stricter __hash__ inheritance rules in 3.0. Several types
4502 which did not meet the rules for hash invariants and were already
4503 unhashable in 3.0 have now been explicitly flagged as unhashable in
4504 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4505 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4506
Brett Cannon88f801d2008-08-18 00:46:22 +00004507- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4508 imported into the module but exposed as part of the module's API.
4509
Brett Cannon7b96f072008-08-18 00:41:11 +00004510- Remove an unneeded import of abc.ABCMeta from 'inspect'.

4515
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004516- Issue #3575: Incremental decoder's decode function now takes bytearray
4517 by using 's*' instead of 't#'.
4518
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004519- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004520 fails unicode conversion on 2nd parameter. (windows only)
4521
Georg Brandl222e2082010-08-01 22:27:39 +00004522- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004523 in a redirect.
4524
Brett Cannonabe423e2008-08-16 21:47:07 +00004525- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004526 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004527
Facundo Batistaeb90b782008-08-16 14:44:07 +00004528- Issue #2776: fixed small issue when handling an URL with double slash
4529 after a 302 response in the case of not going through a proxy.
4530
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004531- Issue #2676: in the email package, content-type parsing was hanging on
4532 pathological input because of quadratic or exponential behaviour of a
4533 regular expression.
4534
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004535- Issue #3476: binary buffered reading through the new "io" library is now
4536 thread-safe.
4537
Brett Cannonbf3157b2008-08-14 05:00:03 +00004538- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4539 since mimetools itself is deprecated. Because modules are cached, all
4540 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4541

4620
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004621- Issue #643841: The language reference now provides more detailed

4633-----------------
4634
Georg Brandl3e483f62008-07-16 22:57:41 +00004635- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4636 its methods now allow for items objects that can be converted to
4637 an integer using operator.index().
4638
Mark Dickinson64b7e502008-07-16 09:40:03 +00004639- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4640 produced a ValueError instead of giving the correct float.
4641
Eric Smitha5fa5a22008-07-16 00:11:49 +00004642- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4643 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4644
Mark Dickinson7103aa42008-07-15 19:08:33 +00004645- Issue #3008: the float type has a new instance method 'float.hex'
4646 and a new class method 'float.fromhex' to convert floating-point
4647 numbers to and from hexadecimal strings, respectively.
4648
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004649- Issue #2235: __hash__ is once again inherited by default. To allow
4650 collections.Hashable to remain meaningful in the presence of the
4651 default hash implementation (object.__hash__), it is now possible
4652 to explicit block inheritance of hash by setting __hash__=None at
4653 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4654 level.
4655
Nick Coghlanb028f502008-07-13 14:52:36 +00004656- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4657 the parent module cannot be found while performing an absolute import.
4658 This means that an incorrectly defined __package__ attribute will
4659 now only prevent relative imports in that module rather than causing
4660 all imports from that module to fail.
4661
Nick Coghlan14ff9942008-07-08 14:21:42 +00004662- Issue #2517: Allow unicode messages in Exceptions again by correctly

4672 another thread's dictionary.
4673
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004674- Issue #3004: Minor change to slice.indices(): the start and stop
4675 arguments are now treated identically, making the behaviour easier
4676 to describe and understand. For example, slice(None, -10,
4677 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4678 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4679 10, -1).
4680
Georg Brandl278fc502008-07-19 12:46:12 +00004681- Issue #3219: Calling a function with repeated keyword arguments,
4682 f(a=2, a=23), would not cause a syntax error. This was a regression
4683 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004685- Issue #2862: Make int and float freelist management consistent with
4686 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004721- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4722 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004723 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004724 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004740- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5109 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00005110
Vinay Sajip9828b7e2008-06-17 11:04:02 +00005111- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005112 environment to control the '-arch' flags that are used to build
5113 an extension. This was added for compatibility with Apple's build
5114 of Python.
5115
5116- The bundled OSX-specific copy of libbffi is now in sync with the version
5117 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
5118
Georg Brandl25c34082008-08-18 23:09:49 +00005119- The threading module gained aliases for names that will be removed in the

5128
Brett Cannonb61d8012008-05-11 23:39:04 +00005129- ``Lib/lib-old`` is now added to sys.path.
5130
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005131- On MacOS X it is now possible to install the framework in 64-bit
5132 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005133 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005134
5135 This is controlled by the configure argument ``--with-universal-archs``:
5136
5137 - ``--with-universal-archs=all``: install 4-way universal
5138
5139 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5140
5141 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5142
5143 This option should be used in combination with ``--enable-universalsdk=``.
5144
5145 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 +00005195- Issue #1631171: Re-implement the 'warnings' module in C (the
5196 original Python code has been kept as backup). This will allow for
5197 using the 'warning's machinery in such places as the parser where
5198 use of pure Python code is not possible. Both the ``showarning()``
5199 and ``formatwarning()`` gain an optional 'line' argument which is
5200 not called by default for backwards-compatibility reasons. Setting
5201 ``warnings.showwarning()`` to an implementation that lacks support
5202 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005227- The getpass module has been improved on Unix. It now uses /dev/tty
5228 by default and uses stderr instead of stdout. A GetPassWarning is
5229 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005244- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005245 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005265- Issue #2550: The approach used by client/server code for obtaining
5266 ports to listen on in network-oriented tests has been refined in an
5267 effort to facilitate running multiple instances of the entire
5268 regression test suite in parallel without issue.
5269 test_support.bind_port() has been fixed such that it will always
5270 return a unique port -- which wasn't always the case with the
5271 previous implementation, especially if socket options had been set
5272 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5273 new implementation of bind_port() will actually raise an exception
5274 if it is passed an AF_INET/SOCK_STREAM socket with either the
5275 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5276 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5277 the socket it's been passed. This currently only applies to
5278 Windows. This option prevents any other sockets from binding to the
5279 host/port we've bound to, thus removing the possibility of the
5280 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5281 when a second SOCK_STREAM socket binds and accepts to a host/port
5282 that's already been bound by another socket. The optional preferred
5283 port parameter to bind_port() has been removed. Under no
5284 circumstances should tests be hard coding ports!
5285
5286 test_support.find_unused_port() has also been introduced, which will
5287 pass a temporary socket object to bind_port() in order to obtain an
5288 unused port. The temporary socket object is then closed and
5289 deleted, and the port is returned. This method should only be used
5290 for obtaining an unused port in order to pass to an external program
5291 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5292 a parameter to a server-oriented class that doesn't give you direct
5293 access to the underlying socket used.
5294
5295 Finally, test_support.HOST has been introduced, which should be used
5296 for the host argument of any relevant socket calls (i.e. bind and
5297 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005298
5299 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005300 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005301 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5302 test_asynchat and test_socket_ssl.
5303
Georg Brandl3ee81df2008-05-17 18:14:43 +00005304 It is now possible for multiple instances of the regression test
5305 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005584- Added the future_builtins module, which contains hex() and oct().
5585 These are the PEP 3127 version of these functions, designed to be
5586 compatible with the hex() and oct() builtins from Python 3.0. They
5587 differ slightly in their output formats from the existing, unchanged
5588 Python 2.6 builtins. The expected usage of the future_builtins
5589 module is:
5590 from future_builtins import hex, oct
5591
Eric Smith7ef40bf2008-02-20 23:34:22 +00005592- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5593 exponents for exponents with absolute value < 100. Follows C99
5594 standard. This is a change on Windows, which would use 3 digits.
5595 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5596 so that any alterations it does to the resulting string will be
5597 available in stringlib/formatter.h (for float.__format__).
5598
Eric Smith5a3c1352008-02-19 13:21:56 +00005599- Implemented PEP 3101, Advanced String Formatting. This adds a new
5600 builtin format(); a format() method for str and unicode; a
5601 __format__() method to object, str, unicode, int, long, float, and
5602 datetime; the class string.Formatter; and the C API
5603 PyObject_Format().
5604
Georg Brandl3ee81df2008-05-17 18:14:43 +00005605- Fixed several potential crashes, all caused by specially crafted
5606 __del__ methods exploiting objects in temporarily inconsistent
5607 state.

5611 a slot on a registered virtual subclass.

5617 in order to allow pymalloc to free more arenas. Python may give back
5618 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005619
Georg Brandl3ee81df2008-05-17 18:14:43 +00005620- Issue #2045: Fix an infinite recursion triggered when printing a
5621 subclass of collections.defaultdict, if its default_factory is set
5622 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005623
Christian Heimesf75dbef2008-02-08 00:11:31 +00005624- Fixed a minor memory leak in dictobject.c. The content of the free
5625 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00005627- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005628 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005629
Georg Brandl3ee81df2008-05-17 18:14:43 +00005630- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5631 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005632 to compact the internal free lists of pre-allocted ints and floats.
5633
Georg Brandl3ee81df2008-05-17 18:14:43 +00005634- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5635 calls. Python expected the return type int but the fork familie
5636 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005637
Georg Brandl3ee81df2008-05-17 18:14:43 +00005638- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5639 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005640
Georg Brandl3ee81df2008-05-17 18:14:43 +00005641- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5642 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005643
Georg Brandl3ee81df2008-05-17 18:14:43 +00005644- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5645 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005647- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5648 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005649
Georg Brandl3ee81df2008-05-17 18:14:43 +00005650- Patch #1473257: generator objects gain a gi_code attribute. This is
5651 the same object as the func_code attribute of the function that
5652 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005653
Georg Brandl3ee81df2008-05-17 18:14:43 +00005654- Issue #1920: "while 0" statements were completely removed by the
5655 compiler, even in the presence of an "else" clause, which is
5656 supposed to be run when the condition is false. Now the compiler
5657 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005658
Guido van Rossumeead05f2008-01-24 18:21:02 +00005659- A few crashers fixed: weakref_in_del.py (issue #1377858);
5660 loosing_dict_ref.py (issue #1303614, test67.py);
5661 borrowed_ref_[34].py (not in tracker).
5662
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005663- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005664 suppressed while an extension is loaded by calling SetErrorMode in
5665 dynload_win.c. The error is still reported properly.
5666
Georg Brandl3ee81df2008-05-17 18:14:43 +00005667- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005668 several extension methods and modules do not work without unicode
5669 support.
5670
Georg Brandl26543b12008-01-21 18:36:51 +00005671- Issue #1882: when compiling code from a string, encoding cookies in the
5672 second line of code were not always recognized correctly.
5673
Georg Brandl14404b62008-01-19 19:27:05 +00005674- Issue #1679: "0x" was taken as a valid integer literal.
5675
Georg Brandl6caad7d2008-01-26 14:19:22 +00005676- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005677 added.
5678
Christian Heimesc94e2b52008-01-14 04:13:37 +00005679- sys.float_info / PyFloat_GetInfo: The floating point information
5680 object was converted from a dict to a specialized structseq object.
5681
Georg Brandl3ee81df2008-05-17 18:14:43 +00005682- Patch #1816: Added sys.flags structseq. It exposes the status of
5683 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005684
Georg Brandl3ee81df2008-05-17 18:14:43 +00005685- Objects/structseq.c: Implemented new structseq representation. The
5686 patch makes structseqs (e.g. the return value of os.stat) more
5687 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005688
Georg Brandl3ee81df2008-05-17 18:14:43 +00005689- Patch #1700288: added a type attribute cache that caches method
5690 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005691
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005692- Bug #1776: __import__() no longer accepts filenames on any platform.
5693 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005694
Georg Brandlaed6c662008-01-07 17:25:53 +00005695- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5696
Georg Brandl3ee81df2008-05-17 18:14:43 +00005697- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5698 envvar and sys.dont_write_bytecode attribute. All these can be set
5699 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005700
Georg Brandl3ee81df2008-05-17 18:14:43 +00005701- Improve some exception messages when Windows fails to load an
5702 extension module. Now we get for example '%1 is not a valid Win32
5703 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005704
Georg Brandl3ee81df2008-05-17 18:14:43 +00005705- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005707- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5708 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005709
Christian Heimes0a8143f2007-12-18 23:22:54 +00005710- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005711 and INF. float("nan"), float("inf") and float("-inf") now work on
5712 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005713
Georg Brandl3ee81df2008-05-17 18:14:43 +00005714- Compiler now generates simpler and faster code for dictionary
5715 literals. The oparg for BUILD_MAP now indicates an estimated
5716 dictionary size. There is a new opcode, STORE_MAP, for adding
5717 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005718
Georg Brandl3ee81df2008-05-17 18:14:43 +00005719- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005727- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005728 SystemError.
5729
Nick Coghlanef01d822007-12-03 12:55:17 +00005730- PEP 366: Allow explicit relative imports when executing modules
5731 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00005746- Patch #1739468: Directories and zipfiles containing a __main__.py
5747 file can now be directly executed by passing their name to the
5748 interpreter. The directory/zipfile is automatically inserted as the
5749 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005750
Georg Brandl3ee81df2008-05-17 18:14:43 +00005751- Issue #1265: Fix a problem with sys.settrace, if the tracing
5752 function uses a generator expression when at the same time the
5753 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005754
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005755- sets and frozensets now have an isdisjoint() method.
5756
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005757- optimize the performance of builtin.sum().
5758
Neal Norwitz44f326e2007-10-05 05:29:17 +00005759- Fix warnings found by the new version of the Coverity checker.
5760
Georg Brandl21e99f42010-03-07 15:23:59 +00005761- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005762 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5763 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005764
Georg Brandl3ee81df2008-05-17 18:14:43 +00005765- Issue #1686386: Tuple's tp_repr did not take into account the
5766 possibility of having a self-referential tuple, which is possible
5767 from C code. Nor did object's tp_str consider that a type's tp_str
5768 could do something that could lead to an inifinite recursion.
5769 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5770 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005771
Georg Brandl3ee81df2008-05-17 18:14:43 +00005772- Issue #1164: It was possible to trigger deadlock when using the
5773 'print' statement to write to a file since the GIL was not released
5774 as needed. Now PyObject_Print() does the right thing along with
5775 various tp_print implementations of the built-in types and those in
5776 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005777
Georg Brandl3ee81df2008-05-17 18:14:43 +00005778- Issue #1147: Exceptions were directly allowing string exceptions in
5779 their throw() method even though string exceptions no longer
5780 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005781
Georg Brandl3ee81df2008-05-17 18:14:43 +00005782- Issue #1096: Prevent a segfault from getting the repr of a very
5783 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005784
Brett Cannon1e534b52007-09-07 04:18:30 +00005785- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005786 PyObject_Call() never calling back out to Python code to trigger
5787 recursion depth updates/checks. Required the creation of a static
5788 RuntimeError instance in case normalizing an exception put the
5789 recursion check value past its limit. Fixes crashers
5790 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005791
Georg Brandl3ee81df2008-05-17 18:14:43 +00005792- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005805- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005806 __*__ attributes. (Some already existed, e.g., __doc__ and
5807 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005808
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005809- Add -3 option to the interpreter to warn about features that are
5810 deprecated and will be changed/removed in Python 3.0.
5811
Georg Brandl2134e752007-05-21 20:34:16 +00005812- Patch #1686487: you can now pass any mapping after '**' in function
5813 calls.
5814
Collin Winter62903052007-05-18 23:11:24 +00005815- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005816 "except E as target:". This is to provide forwards compatibility
5817 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00005819- Deprecate BaseException.message as per PEP 352.
5820
Georg Brandl3ee81df2008-05-17 18:14:43 +00005821- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005822 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005824- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005825 setting a plain string, ie don't expand to single letter identifiers.
5826
Raymond Hettinger13936692007-04-11 18:40:58 +00005827- Request #1191699: Slices can now be pickled.
5828
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005829- Request #1193128: str.translate() now allows a None argument for
5830 translations that only remove characters without re-mapping the
5831 remaining characters.
5832
Georg Brandl5cb76c12007-03-21 09:00:39 +00005833- Patch #1682205: a TypeError while unpacking an iterable is no longer
5834 masked by a generic one with the message "unpack non-sequence".
5835
Neal Norwitzaa754b72007-03-21 06:39:48 +00005836- Remove unused file Python/fmod.c.
5837
Guido van Rossum143b5642007-03-23 04:58:42 +00005838- Bug #1683368: The object.__init__() and object.__new__() methods are
5839 now stricter in rejecting excess arguments. The only time when
5840 either allows excess arguments is when it is not overridden and the
5841 other one is. For backwards compatibility, when both are
5842 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005843 warning later). Also, type.__init__() insists on the same signature
5844 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005845
Georg Brandl3ee81df2008-05-17 18:14:43 +00005846- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5847 object to complex using its __complex__() method before falling back
5848 to the __float__() method. Therefore, the functions in the cmath
5849 module now can operate on objects that define a __complex__()
5850 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006924 time so that opening a database previously created with the DB_DUP
6925 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6926 opens. Specifically: dictionary assignment to a DB object will
6927 replace all values for a given key when the database allows
6928 duplicate values. DB users should use DB.put(k, v) when they want
6929 to store duplicates; not DB[k] = v.

6936 characters with ASCII value less than 32. Also, it correctly quotes
6937 dots only if they occur on a single line, as opposed to the previous
6938 behavior of quoting dots if they are the second character of any
6939 line.
