Neal Norwitz7a5fc282006-05-15 06:48:14 +000010*Release date: XX-MAY-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Tim Petersb713ec22006-05-23 18:45:30 +000015- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
16 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
17 an integer close to ``sys.maxint``. This was repaired by patch
18 #1335972, which also gives a nice speedup.
19
Richard Jonescebbefc2006-05-23 18:28:17 +000020- Patch #1337051: reduced size of frame objects.
21
22- PyErr_NewException now accepts a tuple of base classes as its
23 "base" parameter.
24
Richard Jones7c88dcc2006-05-23 10:37:38 +000025- Patch #876206: function call speedup by retaining allocated frame
26 objects.
27
Georg Brandl7b90e162006-05-18 07:01:27 +000028- Bug #1462152: file() now checks more thoroughly for invalid mode
29 strings and removes a possible "U" before passing the mode to the
30 C library function.
31
Neal Norwitz1004a532006-05-15 07:17:23 +000032- Patch #1488312, Fix memory alignment problem on SPARC in unicode
33
Neal Norwitz373f0a72006-05-15 07:04:36 +000034- Bug #1487966: Fix SystemError with conditional expression in assignment
35
Martin v. Löwis879768d2006-05-11 13:28:43 +000036- WindowsError now has two error code attributes: errno, which carries
37 the error values from errno.h, and winerror, which carries the error
38 values from winerror.h. Previous versions put the winerror.h values
39 (from GetLastError()) into the errno attribute.
40
Martin v. Löwis77736712006-05-04 05:51:03 +000041- Patch #1475845: Raise IndentationError for unexpected indent.
42
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000043- Patch #1479181: split open() and file() from being aliases for each other.
44
Neal Norwitz7a5fc282006-05-15 06:48:14 +000045Extension Modules
46-----------------
47
Georg Brandl378d5922006-05-17 14:26:50 +000048- Patch #1490224: time.altzone is now set correctly on Cygwin.
49
Georg Brandl8d3342b2006-05-16 07:38:27 +000050- Patch #1435422: zlib's compress and decompress objects now have a
51 copy() method.
52
Neal Norwitz7a5fc282006-05-15 06:48:14 +000053- On Win32, os.listdir now supports arbitrarily-long Unicode path names
54 (up to the system limit of 32K characters).
55
56- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
57 As a result, these functions now raise WindowsError instead of OSError.
58
59- Calling Tk_Init twice is refused if the first call failed as that
60 may deadlock.
61
62Library
63-------
64
Bob Ippolito7298f272006-05-23 18:43:47 +000065- Patch #1281707: speed up gzip.readline.
66
Georg Brandlb89316f2006-05-17 15:51:16 +000067- Patch #1180296: Two new functions were added to the locale module:
68 format_string() to get the effect of "format % items" but locale-aware,
69 and currency() to format a monetary number with currency sign.
70
Georg Brandle3a25832006-05-17 14:56:04 +000071- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
72 and several features added, such as speed and geometry control.
73
Georg Brandl49c8f4c2006-05-15 19:30:35 +000074- Patch #1488881: add support for external file objects in bz2 compressed
75 tarfiles.
76
Neal Norwitz7a5fc282006-05-15 06:48:14 +000077- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
78 stdout arguments, making it possible to redirect input and output
79 for remote debugging.
80
81- Patch #1484695: Update the tarfile module to version 0.8. This fixes
82 a couple of issues, notably handling of long file names using the
83 GNU LONGNAME extension.
84
85- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
86 new flag when ``name`` is already the name of an option flag.
87
88- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
89 package.
90
91- Patch #1472854: make the rlcompleter.Completer class usable on non-
92 UNIX platforms.
93
94- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

117What's New in Python 2.5 alpha 2?
118=================================
119
120*Release date: 27-APR-2006*
121
122Core and builtins
123-----------------
124
Thomas Heller1b046642006-04-18 18:51:06 +0000125- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
126 by converting these apis from macros into exported functions again:
127
128 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
129 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
130 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
131 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
132 PyRun_String Py_CompileString
133
Martin v. Löwis45294a92006-04-18 06:24:08 +0000134- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
135
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000136- All uses of PyStructSequence_InitType have been changed to initialize
137 the type objects only once, even if the interpreter is initialized
138 multiple times.
139
Neal Norwitz61546162006-04-14 05:20:28 +0000140- Bug #1454485, array.array('u') could crash the interpreter. This was
141 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
142 to unicode when it didn't make sense. 'u#' now requires a unicode string.
143
144- Py_UNICODE is unsigned. It was always documented as unsigned, but
145 due to a bug had a signed value in previous versions.
146
Tim Peters3a5e8b12006-04-11 01:44:07 +0000147- Patch #837242: ``id()`` of any Python object always gives a positive
148 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
149 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000150 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000151 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000152
Tim Peters3a5e8b12006-04-11 01:44:07 +0000153 def __hash__(self):
154 return id(self) # WRONG
155
156 because a hash result must be a (short) Python int but it was always
157 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000158 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000159 was always usable as a hash value before this patch. That's no longer
160 necessarily so.
161
162- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000163 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000164 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000165 #1454844)
166
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000167- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
168 involving generators that have paused outside of any ``try`` or ``with``
169 blocks. (In 2.5a1, a paused generator that was part of a reference
170 cycle could not be garbage collected, regardless of whether it was
171 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000173Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000176- Patch #1191065: Fix preprocessor problems on systems where recvfrom
177 is a macro.
178
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000179- Bug #1467952: os.listdir() now correctly raises an error if readdir()
180 fails with an error condition.
181
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000182- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
183
184- Bug #1117761: bsddb.*open() no longer raises an exception when using
185 the cachesize parameter.
186
187- Bug #1149413: bsddb.*open() no longer raises an exception when using
188 a temporary db (file=None) with the 'n' flag to truncate on open.
189
190- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
191 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000192
Armin Rigoa9017c32006-04-19 11:50:27 +0000193- Patch #1062014: AF_UNIX sockets under Linux have a special
194 abstract namespace that is now fully supported.
195
Anthony Baxter51bcb682006-04-05 14:51:42 +0000196Library
197-------
198
Tim Peters711bf302006-04-25 03:31:36 +0000199- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
200 a doctest to be skipped (the code is not run, and the expected output
201 or exception is ignored).
202
Nick Coghlanda2268f2006-04-24 04:37:15 +0000203- Fixed contextlib.nested to cope with exceptions being raised and
204 caught inside exit handlers.
205
Greg Wardab05edc2006-04-23 03:47:58 +0000206- Updated optparse module to Optik 1.5.1 (allow numeric constants in
207 hex, octal, or binary; add ``append_const`` action; keep going if
208 gettext cannot be imported; added ``OptionParser.destroy()`` method;
209 added ``epilog`` for better help generation).
210
Tim Peters21fbd572006-04-21 21:18:10 +0000211- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
212 called from a thread spawned as a side effect of importing a module.
213
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000214- The pydoc module now supports documenting packages contained in
215 .zip or .egg files.
216
217- The pkgutil module now has several new utility functions, such
218 as ``walk_packages()`` to support working with packages that are either
219 in the filesystem or zip files.
220
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000221- The mailbox module can now modify and delete messages from
222 mailboxes, in addition to simply reading them. Thanks to Gregory
223 K. Johnson for writing the code, and to the 2005 Google Summer of
224 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000225
Tim Petersc7605f22006-04-17 21:12:33 +0000226- The ``__del__`` method of class ``local`` in module ``_threading_local``
227 returned before accomplishing any of its intended cleanup.
228

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000233- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
234
Anthony Baxtere29002c2006-04-12 12:07:31 +0000235- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
236 Windows. Bug #1469163.
237
Phillip J. Eby47032112006-04-11 01:07:43 +0000238- The warnings, linecache, inspect, traceback, site, and doctest modules
239 were updated to work correctly with modules imported from zipfiles or
240 via other PEP 302 __loader__ objects.
241
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000242- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000262- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
263 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000264 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000265 CXX from --with-cxx-main, see description in README.
266
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000267- Patch #1429775: Link extension modules with the shared libpython.
268

282
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000283- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
284 it separately and by hand. It also wasn't cleaning up its changes to
285 the current Decimal context.
286
Thomas Woutersabd08882006-04-26 15:53:30 +0000287- regrtest.py now has a -M option to run tests that test the new limits of
288 containers, on 64-bit architectures. Running these tests is only sensible
289 on 64-bit machines with more than two gigabytes of memory. The argument
290 passed is the maximum amount of memory for the tests to use.

318
Nick Coghlan43832302006-04-23 17:04:07 +0000319- PEP 338: -m command line switch now delegates to runpy.run_module
320 allowing it to support modules in packages and zipfiles
321
Martin v. Löwisc661b882006-04-20 04:54:23 +0000322- On Windows, .DLL is not an accepted file name extension for
323 extension modules anymore; extensions are only found if they
324 end in .PYD.
325
Martin v. Löwisea62d252006-04-03 10:56:49 +0000326- Bug #1421664: sys.stderr.encoding is now set to the same value as
327 sys.stdout.encoding.

336 5.4 and later versions.
337
Neal Norwitze98ccf62006-03-23 05:39:47 +0000338- Bug #1115379: Compiling a Unicode string with an encoding declaration
339 now gives a SyntaxError.
340
Georg Brandlabd1ff82006-03-18 07:59:59 +0000341- Previously, Python code had no easy way to access the contents of a
342 cell object. Now, a ``cell_contents`` attribute has been added
343 (closes patch #1170323).
344
Tim Peterscf79aac2006-03-16 01:14:46 +0000345- Patch #1123430: Python's small-object allocator now returns an arena to
346 the system ``free()`` when all memory within an arena becomes unused
347 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
348 freed. Some applications will see a drop in virtual memory size now,
349 especially long-running applications that, from time to time, temporarily
350 use a large number of small objects. Note that when Python returns an
351 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000352 platform C library will in turn return that memory to the operating system.
353 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000354 appears to be effective at least on Microsoft C and gcc-based systems.
355 Thanks to Evan Jones for hard work and patience.
356
Georg Brandl533ff6f2006-03-08 18:09:27 +0000357- Patch #1434038: property() now uses the getter's docstring if there is
358 no "doc" argument given. This makes it possible to legitimately use
359 property() as a decorator to produce a read-only property.
360
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000361- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
362 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
363 of requiring an int or long in slicing and a few other contexts, enabling
364 other objects (e.g. Numeric Python's integers) to be used as slice indices.
365
Neal Norwitz995acdf2006-03-07 05:01:00 +0000366- Fixed various bugs reported by Coverity's Prevent tool.
367
Brett Cannonbf364092006-03-01 04:25:17 +0000368- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
369 new exception base class, BaseException, which has a new message attribute.
370 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
371 Raising a string exception now raises a DeprecationWarning.
372
Thomas Woutersfb609f42006-02-28 16:37:25 +0000373- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
374 explicitly relative, using 'from .module import name' to mean 'from the same
375 package as this module is in. Imports without dots still default to the
376 old relative-then-absolute, unless 'from __future__ import
377 absolute_import' is used.
378
Brett Cannona7446e32006-02-27 23:39:10 +0000379- Properly check if 'warnings' raises an exception (usually when a filter set
380 to "error" is triggered) when raising a warning for raising string
381 exceptions.
382
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000383- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000384 The name was removed from Include/code.h.
385
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000386- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000387
Guido van Rossum1968ad32006-02-25 22:38:04 +0000388- Patch 1433928:
389 - The copy module now "copies" function objects (as atomic objects).
390 - dict.__getitem__ now looks for a __missing__ hook before raising
391 KeyError.
392
Tim Peters84ef21c2006-02-28 20:39:06 +0000393- PEP 343: with statement implemented. Needs ``from __future__ import
394 with_statement``. Use of 'with' as a variable will generate a warning.
395 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000396 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000397 The following objects have __context__ methods:
398 - The built-in file type.
399 - The thread.LockType type.
400 - The following types defined by the threading module:
401 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
402 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000403
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000404- Fix the encodings package codec search function to only search
405 inside its own package. Fixes problem reported in patch #1433198.
406
407 Note: Codec packages should implement and register their own
408 codec search function. PEP 100 has the details.
409
Martin v. Löwis18e16552006-02-15 17:27:45 +0000410- PEP 353: Using ssize_t as the index type.
411
Neal Norwitzfc76d632006-01-10 06:03:13 +0000412- Patch #1400181, fix unicode string formatting to not use the locale.
413 This is how string objects work. u'%f' could use , instead of .
414 for the decimal point. Now both strings and unicode always use periods.
415
Neal Norwitz671b9e32006-01-09 07:07:12 +0000416- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
417 configure would break checking curses.h.
418
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000419- Bug #959576: The pwd module is now builtin. This allows Python to be
420 built on UNIX platforms without $HOME set.
421
Neal Norwitzc10978f2005-12-19 06:07:16 +0000422- Bug #1072182, fix some potential problems if characters are signed.
423
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000424- Bug #889500, fix line number on SyntaxWarning for global declarations.
425
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000426- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
427
Neal Norwitze7214a12005-12-18 05:03:17 +0000428- Support for converting hex strings to floats no longer works.
429 This was not portable. float('0x3') now raises a ValueError.
430
Barry Warsaw2a38a862005-12-18 01:27:35 +0000431- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000432 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000433 is now displayed in interactive prompt banner.
434
Georg Brandlfa166682005-12-17 21:45:17 +0000435- Implementation of PEP 341 - Unification of try/except and try/finally.
436 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000437 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000438
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000439- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
440 now encodes backslash correctly.
441
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000442- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
443
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000444- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000445 and long longs.
446
Neal Norwitz67715f02005-11-09 06:59:35 +0000447- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000448 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000449 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000450
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000451- Replaced most Unicode charmap codecs with new ones using the
452 new Unicode translate string feature in the builtin charmap
453 codec; the codecs were created from the mapping tables available
454 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
455 encodings now include a mapping for the Apple logo)
456
Tim Peterse3547fd2005-12-16 23:13:57 +0000457- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000458
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000459- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000460
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000461- A new AST parser implementation was completed. The abstract
462 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000463 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000464
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000465- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000466 The following code now raises a SyntaxError: foo(a = i for i in range(10))
467
Neal Norwitz708e51a2005-10-03 04:48:15 +0000468- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
469
Neal Norwitz11bd1192005-10-03 00:54:56 +0000470- SF Bug #887946: fix segfault when redirecting stdin from a directory.
471 Provide a warning when a directory is passed on the command line.
472
Neal Norwitz40d37812005-10-02 01:48:49 +0000473- Fix segfault with invalid coding.
474
475- SF bug #772896: unknown encoding results in MemoryError.
476
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000477- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000478 supported a __len__() method which evaluated to False when the iterator
479 was empty.
480
Guido van Rossum630db602005-09-20 18:49:54 +0000481- On 64-bit platforms, when __len__() returns a value that cannot be
482 represented as a C int, raise OverflowError.
483
Skip Montanarof8948ca2005-09-19 03:54:46 +0000484- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000485 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000486
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000487- SF bug #893549: parsing keyword arguments was broken with a few format
488 codes.
489
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000490- Changes donated by Elemental Security to make it work on AIX 5.3
491 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
492 bug #105470: test_pwd fails on 64bit system (Opteron).
493
Guido van Rossum539c6622005-09-14 17:49:54 +0000494- Changes donated by Elemental Security to make it work on HP-UX 11 on
495 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
496
Georg Brandl4550b8d2005-08-26 06:43:52 +0000497- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000498 (fixes bug #1119418).
499
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000500- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
501
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000502- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
503 exceptions that cause a function to exit.
504
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000505- The implementation of set() and frozenset() was revised to use its
506 own internal data structure. Memory consumption is reduced by 1/3
507 and there are modest speed-ups as well. The API is unchanged.
508
Tim Petersde7990b2005-07-17 23:45:23 +0000509- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
510
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000511- SF bug #1229429: PyObject_CallMethod failed to decrement some
512 reference counts in some error exit cases.
513
Tim Petersecc6e6a2005-07-10 22:30:55 +0000514- SF bug #1185883: Python's small-object memory allocator took over
515 a block managed by the platform C library whenever a realloc specified
516 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000517 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000518 portable way to copy data from the C-managed block into Python's
519 small-object space without risking a memory fault. Python's small-object
520 realloc now leaves such blocks under the control of the platform C
521 realloc.
522
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000523- SF bug #1232517: An overflow error was not detected properly when
524 attempting to convert a large float to an int in os.utime().
525
Raymond Hettinger3296e692005-06-29 23:29:56 +0000526- SF bug #1224347: hex longs now print with lowercase letters just
527 like their int counterparts.
528
Michael W. Hudson188d4362005-06-20 16:52:57 +0000529- SF bug #1163563: the original fix for bug #1010677 ("thread Module
530 Breaks PyGILState_Ensure()") broke badly in the case of multiple
531 interpreter states; back out that fix and do a better job (see
532 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
533 for a longer write-up of the problem).
534
Michael W. Hudsondf888462005-06-03 14:41:55 +0000535- SF patch #1180995: marshal now uses a binary format by default when
536 serializing floats.
537
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000538- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
539 the routines that promise to produce IEEE 754 binary representations
540 of floats now simply copy bytes around.
541
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000542- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
543 278.
544
Brett Cannonc3647ac2005-04-26 03:45:26 +0000545- patch #1109424: int, long, float, complex, and unicode now check for the
546 proper magic slot for type conversions when subclassed. Previously the
547 magic slot was ignored during conversion. Semantics now match the way
548 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000549 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000550 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000551 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000552
Barry Warsawc8d907c2005-04-19 23:43:40 +0000553- Descriptors defined in C with a PyGetSetDef structure, where the setter is
554 NULL, now raise an AttributeError when attempting to set or delete the
555 attribute. Previously a TypeError was raised, but this was inconsistent
556 with the equivalent pure-Python implementation.
557
Michael W. Hudson774479c2005-04-18 08:46:17 +0000558- It is now safe to call PyGILState_Release() before
559 PyEval_InitThreads() (note that if there is reason to believe there
560 are multiple threads around you still must call PyEval_InitThreads()
561 before using the Python API; this fix is for extension modules that
562 have no way of knowing if Python is multi-threaded yet).
563
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000564- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
565 disabled caused a crash.
566
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000567- Bug #1165306: instancemethod_new allowed the creation of a method
568 with im_class == im_self == NULL, which caused a crash when called.
569
Tim Petersecc6e6a2005-07-10 22:30:55 +0000570- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000571 fixes the crash seen in bug #1165761
572
Raymond Hettinger96229b12005-03-11 06:49:40 +0000573- Added two new builtins, any() and all().
574
Brett Cannon409d8f22005-03-05 06:47:57 +0000575- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000576 (e.g., ``class C(): pass`` is no longer a syntax error).
577 Patch #1176012 added support to the 'parser' module and 'compiler' package
578 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000579
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000580- Patch #1115086: Support PY_LONGLONG in structmember.
581
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000582- Bug #1155938: new style classes did not check that __init__() was
583 returning None.
584
Tim Petersecc6e6a2005-07-10 22:30:55 +0000585- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000586 ('\') with a specific error message.
587
Martin v. Löwisff232d72005-03-03 09:24:38 +0000588- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
589
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000590- Bug #1124295: the __name__ attribute of file objects was
591 inadvertently made inaccessible in restricted mode.
592
Tim Petersecc6e6a2005-07-10 22:30:55 +0000593- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000594 an ferror() call.
595
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000596- min() and max() now support key= arguments with the same meaning as in
597 list.sort().
598
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000599- The peephole optimizer now performs simple constant folding in expressions:
600 (2+3) --> (5).
601
Raymond Hettingera422c342005-01-11 03:03:27 +0000602- set and frozenset objects can now be marshalled. SF #1098985.
603
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000604- Bug #1077106: Poor argument checking could cause memory corruption
605 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000606
Jeremy Hyltonab630502005-02-04 18:44:06 +0000607- The parser did not complain about future statements in illegal
608 positions. It once again reports a syntax error if a future
609 statement occurs after anything other than a doc string.
610
Neil Schemenauercf52c072005-08-12 17:34:58 +0000611- Change the %s format specifier for str objects so that it returns a
612 unicode instance if the argument is not an instance of basestring and
613 calling __str__ on the argument returns a unicode instance.
614
Tim Petersf4e69282006-02-27 17:15:31 +0000615- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
616 current thread state when the auto-GIL-state machinery knows about
617 it (since the thread state is being deleted, continuing to remember it
618 can't help, but can hurt if another thread happens to get created with
619 the same thread id).

Michael W. Hudson8137bea2005-07-27 20:24:40 +0000751- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
752 the request code argument, which results in more C-like behaviour
753 for large or negative values.
754
Tim Petersecc6e6a2005-07-10 22:30:55 +0000755- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlaf410b52005-07-08 22:26:13 +0000757
Georg Brandl6b95f1d2005-06-03 19:47:00 +0000758- Bug #1194181: bz2.BZ2File didn't handle mode 'U' correctly.

797
Raymond Hettingerb2594052004-12-05 09:25:51 +0000798- itertools.islice() now accepts None for the start and step arguments.
799 This allows islice() to work more readily with slices:

807
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000808Library
809-------
810
Nick Coghlan43832302006-04-23 17:04:07 +0000811- PEP 338: new module runpy defines a run_module function to support
812 executing modules which provide access to source code or a code object
813 via the PEP 302 import mechanisms.
814
Anthony Baxter93f5b932006-04-03 08:05:07 +0000815- The email module's parsedate_tz function now sets the daylight savings
816 flag to -1 (unknown) since it can't tell from the date whether it should
817 be set.
818
Fred Drakead5177c2006-04-01 22:14:43 +0000819- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results

823 in attribute values.
824
Anthony Baxterc51ee692006-04-01 00:57:31 +0000825- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000826 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000827 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000828 module will not be built.
829
Tim Petersc17976e2006-04-01 00:26:53 +0000830- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
831 aren't officially supported here, and trying to use them will probably
832 raise an exception some day. But dicts have been allowed, and "mostly
833 worked", so support for them won't go away without warning.
834
Georg Brandl338ef7d2006-03-31 18:42:16 +0000835- Bug #1445068: getpass.getpass() can now be given an explicit stream
836 argument to specify where to write the prompt.
837
Georg Brandl22ec80b2006-03-31 18:25:44 +0000838- Patch #1462313, bug #1443328: the pickle modules now can handle classes

853
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000854- email 4.0 package now integrated. This is largely the same as the email 3.0
855 package that was included in Python 2.3, except that PEP 8 module names are
856 now used (e.g. mail.message instead of email.Message). The MIME classes
857 have been moved to a subpackage (e.g. email.mime.text instead of
858 email.MIMEText). The old names are still supported for now. Several
859 deprecated Message methods have been removed and lots of bugs have been
860 fixed. More details can be found in the email package documentation.
861
Walter Dörwald40108c92006-03-27 08:15:44 +0000862- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
863 (a subclass of tuple) that provides incremental decoders and encoders
864 (a way to use stateful codecs without the stream API). Python functions
865 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
866 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
867 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000868
Walter Dörwald067db482006-03-15 22:17:27 +0000869- Patch #1359365: Calling next() on a closed StringIO.String object raises
870 a ValueError instead of a StopIteration now (like file and cString.String do).
871 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
872 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000873
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000874- A regrtest option -w was added to re-run failed tests in verbose mode.

880 grew an optional 'generation' argument.
881
Martin v. Löwisfbab90e2006-03-05 13:36:04 +0000882- A library msilib to generate Windows Installer files, and a distutils

953 is that SHA-256 is a good choice for the time being, but
954 that research should continue, and other alternatives may
955 arise from this research. The larger SHA's also seem OK."

1144 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001145 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001146 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001147 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1148 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001149 + reader now allows \r characters to be quoted (previously it only allowed
1150 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001151 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001152 + Dialect classes passed to the module are no longer instantiated by
1153 the module before being parsed (the former validation scheme required
1154 this, but the mechanism was unreliable).
1155 + The dialect registry now contains instances of the internal
1156 C-coded dialect type, rather than references to python objects.
1157 + the internal c-coded dialect type is now immutable.
1158 + register_dialect now accepts the same keyword dialect specifications
1159 as the reader and writer, allowing the user to register dialects
1160 without first creating a dialect class.
1161 + a configurable limit to the size of parsed fields has been added -
1162 previously, an unmatched quote character could result in the entire
1163 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001164 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001165 the parser field size limit (returning the former limit). The initial
1166 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001167 + A line_num attribute has been added to the reader object, which tracks
1168 the number of lines read from the source iterator. This is not
1169 the same as the number of records returned, as records can span
1170 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001171 + reader and writer objects were not being registered with the cyclic-GC.
1172 This has been fixed.
1173
Brett Cannone6539c42005-01-08 02:43:53 +00001174- _DummyThread objects in the threading module now delete self.__block that is
1175 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1176 lock primitives tend to be limited in number and thus should not be wasted on
1177 a _DummyThread object. Fixes bug #1089632.
1178
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001179- The imghdr module now detects Exif files.
1180
Raymond Hettinger6065d322004-12-20 23:51:53 +00001181- StringIO.truncate() now correctly adjusts the size attribute.
1182 (Bug #951915).
1183
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001184- locale.py now uses an updated locale alias table (built using
1185 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1186 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001187 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001188
Raymond Hettinger3557f422004-12-07 12:02:02 +00001189- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1190
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001191- the pickle module no longer accepts the deprecated None option in the
1192 args tuple returned by __reduce__().
1193
Brett Cannon84667c02004-12-07 03:25:18 +00001194- optparse now optionally imports gettext. This allows its use in setup.py.
1195
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001196- the pickle module no longer uses the deprecated bin parameter.
1197
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001198- the shelve module no longer uses the deprecated binary parameter.
1199
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001200- the pstats module no longer uses the deprecated ignore() method.
1201
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001202- the filecmp module no longer uses the deprecated use_statcache argument.
1203
Raymond Hettinger664347b2004-12-04 21:21:53 +00001204- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1205 extended or overridden by subclasses. Formerly, the subclassed method would
1206 be ignored by the rest of the module. (Bug #1078905).
1207
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001208- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001209 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001210
Walter Dörwald36733692004-12-22 12:50:50 +00001211- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1212 once when a size argument is given. This prevents a buffer overflow in the
1213 tokenizer with very long source lines.
1214
Barry Warsaw538561e2006-01-01 21:48:54 +00001215- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1216 immediately after creating the object, without any intervening
1217 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001218
Skip Montanaro05885812005-01-16 20:48:27 +00001219- The reconvert.quote function can now emit triple-quoted strings. The
1220 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001221
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001222- ``UserString.MutableString`` now supports negative indices in
1223 ``__setitem__`` and ``__delitem__``
1224
Greg Ward40407942005-03-05 02:53:17 +00001225- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1226 correctly.
1227
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001228- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1229 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1230 character even if the user has passed a size parameter to get a proper
1231 line ending. Remove the special handling of a "\r\n" that has been split
1232 between two lines.
1233
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001234- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1235 about illegal code points. The codec now supports PEP 293 style error
1236 handlers.
1237
Walter Dörwald78a78b02005-09-01 12:04:29 +00001238- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001239 from the input stream, so that the output is a byte string in the correct
1240 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001241
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001242- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1243 considering it exactly like a '*'.
1244
Walter Dörwald007f8df2005-10-09 19:42:27 +00001245- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1246 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001247
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001248- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1249
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001250- Patch #1413711: Certain patterns of differences were making difflib
1251 touch the recursion limit.
1252
Walter Dörwald58917a62006-03-31 15:26:22 +00001253- Bug #947906: An object oriented interface has been added to the calendar
1254 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001255 called as a script (e.g. via ``python -mcalendar``). Localized month and
1256 weekday names can be ouput (even if an exotic encoding is used) using
1257 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001258
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001259Build
1260-----
1261
Neal Norwitz602d3392006-03-31 08:21:40 +00001262- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1263 by using -mieee gcc option.
1264
Martin v. Löwis86d66262006-02-17 08:40:11 +00001265- Patch #1432345: Make python compile on DragonFly.
1266
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001267- Build support for Win64-AMD64 was added.
1268
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001269- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1270
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001271- Patch #881820: look for openpty and forkpty also in libbsd.
1272
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001273- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1274 The zlib module is now builtin on Windows.
1275
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001276- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1277
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001278- Bug #1189330: configure did not correctly determine the necessary
1279 value of LINKCC if python was built with GCC 4.0.
1280
Trent Mick8321b422005-07-26 02:29:21 +00001281- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1282 vulnerability in zlib 1.2.1 and 1.2.2.
1283
Brett Cannon08cd5982005-04-24 22:26:38 +00001284- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1285 flags that change binary compatibility. Changes were also made to
1286 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001287 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001288
Bob Ippolitoed233462005-03-29 13:47:59 +00001289- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1290 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1291 no longer exists). This configure patch makes things right.
1292
Martin v. Löwise2713be2005-03-08 15:03:08 +00001293- Bug #1158607: Build with --disable-unicode again.
1294
Brett Cannon46d96232005-02-16 00:07:19 +00001295- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1296 defined. Discovered as a result of not being able to build on OS X.
1297
Brett Cannon516592f2004-12-07 00:42:59 +00001298- setup.py now uses the directories specified in LDFLAGS using the -L option
1299 and in CPPFLAGS using the -I option for adding library and include
1300 directories, respectively, for compiling extension modules against. This has
1301 led to the core being compiled using the values in CPPFLAGS. It also removes
1302 the need for the special-casing of both DarwinPorts and Fink for darwin since
1303 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1304 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1305 Fink, ``-I/opt/local/include`` for DarwinPorts).
1306
Brett Cannon43802422005-02-10 20:48:03 +00001307- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1308 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1309 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1310 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001312C API
1313-----
1314
Tim Petersc9d78aa2006-03-26 23:27:58 +00001315- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1316 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1317 is obtained via the ``PyObject_`` family, it must be released via the
1318 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1319 always been officially true, but when Python's small-object allocator was
1320 introduced, an attempt was made to cater to a few extension modules
1321 discovered at the time that obtained memory via ``PyObject_New`` but
1322 released it via ``PyMem_DEL``. It's years later, and if such code still
1323 exists it will fail now (probably with segfaults, but calling wrong
1324 low-level memory management functions can yield many symptoms).
1325
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001326- Added a C API for set and frozenset objects.
1327
Raymond Hettinger66517482004-12-03 11:45:13 +00001328- Removed PyRange_New().
1329
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001330- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1331 mapping argument now. This string is used as a mapping table. Byte values
1332 greater than the length of the string and 0xFFFE are treated as undefined
1333 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001340
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001341- Patch #1276356: New resource "urlfetch" is implemented. This enables
