Georg Brandl9dceedb2006-07-12 15:31:17 +000015- Patch #1521179: Python now accepts the standard options ``--help`` and
16 ``--version`` as well as ``/?`` on Windows.
17
Neal Norwitza1f10902006-07-12 07:28:29 +000018- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
19 again. Fixing this problem required changing the .pyc magic number.
20 This means that .pyc files generated before 2.5c1 will be regenerated.

38
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000039- Bug #1441486: The literal representation of -(sys.maxint - 1)
40 again evaluates to a int object, not a long.
41
Neil Schemenauer0e07b602006-07-09 16:16:34 +000042- Bug #1501934: The scope of global variables that are locally assigned
43 using augmented assignment is now correctly determined.
44
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000045- Bug #927248: Recursive method-wrapper objects can now safely
46 be released.
47
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000048- Bug #1417699: Reject locale-specific decimal point in float()
49 and atof().
50
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000051- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
52 omit a default "error" argument for NULL pointer. This allows
53 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000054
Neal Norwitzfb48afa2006-07-08 05:31:37 +000055- Bug #1519018: 'as' is now validated properly in import statements.
56
Neal Norwitz28746ab2006-07-09 22:14:42 +000057- On 64 bit systems, int literals that use less than 64 bits are
58 now ints rather than longs.
59
Neal Norwitzed657552006-07-10 00:04:44 +000060- Bug #1512814, Fix incorrect lineno's when code at module scope
61 started after line 256.
62
Tim Peters32a83612006-07-10 21:08:24 +000063- New function ``sys._current_frames()`` returns a dict mapping thread
64 id to topmost thread stack frame. This is for expert use, and is
65 especially useful for debugging application deadlocks. The functionality
66 was previously available in Fazal Majid's ``threadframe`` extension
67 module, but it wasn't possible to do this in a wholly threadsafe way from
68 an extension.

Martin v. Löwis8d656812006-07-10 07:23:48 +000076 environment variable to be set in order to the SDK environment
77 for finding the compiler, include files, etc.
78
Martin v. Löwis388a8c22006-07-06 19:28:03 +000079- Bug #1515998: Properly generate logical ids for files in bdist_msi.
80
Nick Coghlan2d792252006-07-06 13:47:18 +000081- warnings.py now ignores ImportWarning by default
82
Thomas Woutersadd19112006-07-05 11:03:49 +000083- string.Template() now correctly handles tuple-values. Previously,
84 multi-value tuples would raise an exception and single-value tuples would
85 be treated as the value they contain, instead.
86
Martin v. Löwisede77f52006-07-03 13:01:35 +000087- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
88 even if some data are received.
89
Martin v. Löwis45482392006-07-03 12:28:58 +000090- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis4c4300d2006-07-03 10:05:30 +000098
Martin v. Löwisbd39c032006-07-03 09:44:00 +000099- Bug #1514703: Only setup canvas window in turtle when the canvas
100 is created.
101
Martin v. Löwis7596e832006-07-01 15:33:37 +0000102- Bug #1513223: .close() of a _socketobj now releases the underlying
103 socket again, which then gets closed as it becomes unreferenced.
104
Fred Drake10497c82006-06-29 02:57:48 +0000105- Bug #1504333: Make sgmllib support angle brackets in quoted
106 attribute values.
107
108- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
109 sgmllib ('[' and ']' were not accepted).
110
Georg Brandl1be63af2006-06-28 20:23:25 +0000111- Fix a bug in the turtle module's end_fill function.
112
Brett Cannon53ab5b72006-06-22 16:49:14 +0000113- Bug #1510580: The 'warnings' module improperly required that a Warning
114 category be either a types.ClassType and a subclass of Warning. The proper
115 check is just that it is a subclass with Warning as the documentation states.
116
Georg Brandlad29e632006-06-21 17:45:17 +0000117- The compiler module now correctly compiles the new try-except-finally
118 statement (bug #1509132).
119
Neal Norwitz60373cd2006-06-22 06:30:50 +0000120- The wsgiref package is now installed properly on Unix.
121
Vinay Sajip28e57612006-07-01 10:45:20 +0000122- A bug was fixed in logging.config.fileConfig() which caused a crash on
123 shutdown when fileConfig() was called multiple times.
124
Gerhard Häring762fbd32006-07-02 17:48:30 +0000125- The sqlite3 module did cut off data from the SQLite database at the first
126 null character before sending it to a custom converter. This has been fixed
127 now.
128
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000129Extension Modules
130-----------------
131
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000132- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
133 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
134 The patch makes sockets use poll() internally where available.
135
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000136- Assigning None to pointer type fields in ctypes structures possible
137 overwrote the wrong fields, this is fixed now.
138
139- Fixed a segfault in _ctypes when ctypes.wintypes were imported
140 on non-Windows platforms.
141
142- Bug #1518190: The ctypes.c_void_p constructor now accepts any
143 integer or long, without range checking.
144
145- Patch #1517790: It is now possible to use custom objects in the ctypes
146 foreign function argtypes sequence as long as they provide a from_param
147 method, no longer is it required that the object is a ctypes type.
148
149- The '_ctypes' extension module now works when Python is configured
150 with the --without-threads option.
151
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000152- Bug #1513646: os.access on Windows now correctly determines write
153 access, again.
154
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000155- Bug #1512695: cPickle.loads could crash if it was interrupted with
156 a KeyboardInterrupt.
157
Neal Norwitza12aa882006-07-06 06:45:08 +0000158- Bug #1296433: parsing XML with a non-default encoding and
159 a CharacterDataHandler could crash the interpreter in pyexpat.
160
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000161- Patch #1516912: improve Modules support for OpenVMS.
162

164-----
165
Tim Peters32a83612006-07-10 21:08:24 +0000166- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000167 Previously, the slight difference could cause compilation errors of the
168 'zlib' module on systems with more than one version of zlib.
169
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000170- The MSI compileall step was fixed to also support a TARGETDIR
171 with spaces in it.
172
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000173- Bug #1517388: sqlite3.dll is now installed on Windows independent
174 of Tcl/Tk.
175
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000176- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000177 trying to be installed even though it's empty.

180-----
181
182- Call os.waitpid() at the end of tests that spawn child processes in order
183 to minimize resources (zombies).
184
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000185Documentation
186-------------
187
Nick Coghlan2d792252006-07-06 13:47:18 +0000188- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
189 documentation for the warnings module.
190
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000191- Patch #1509163: MS Toolkit Compiler no longer available.
192
Neal Norwitz56640df2006-07-10 02:36:41 +0000193- Patch #1504046: Add documentation for xml.etree.

200Core and builtins
201-----------------
202
Georg Brandla56b9152006-06-19 06:35:54 +0000203- Patch #1507676: Error messages returned by invalid abstract object operations
204 (such as iterating over an integer) have been improved and now include the
205 type of the offending object to help with debugging.
206
Brett Cannonea3912b2006-06-13 21:46:41 +0000207- Bug #992017: A classic class that defined a __coerce__() method that returned
208 its arguments swapped would infinitely recurse and segfault the interpreter.
209
Neal Norwitz909eb122006-06-12 02:13:21 +0000210- Fix the socket tests so they can be run concurrently.
211
Neal Norwitzb9845e72006-06-12 02:11:18 +0000212- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000213 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000214
Brett Cannon22565aa2006-06-09 22:31:23 +0000215- Bug #532646: object.__call__() will continue looking for the __call__
216 attribute on objects until one without one is found. This leads to recursion
217 when you take a class and set its __call__ attribute to an instance of the
218 class. Originally fixed for classic classes, but this fix is for new-style.
219 Removes the infinite_rec_3 crasher.
220
Georg Brandl24250812006-06-09 18:45:48 +0000221- The string and unicode methods startswith() and endswith() now accept
222 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
223
Brett Cannonde3b0522006-06-08 17:00:45 +0000224- Buffer objects, at the C level, never used the char buffer
225 implementation even when the char buffer for the wrapped object was
226 explicitly requested (originally returned the read or write buffer).
227 Now a TypeError is raised if the char buffer is not present but is
228 requested.
229
Georg Brandlddbaa662006-06-04 21:56:52 +0000230- Patch #1346214: Statements like "if 0: suite" are now again optimized
231 away like they were in Python 2.4.
232
Georg Brandlb7c8f542006-05-27 12:30:25 +0000233- Builtin exceptions are now full-blown new-style classes instead of
234 instances pretending to be classes, which speeds up exception handling
235 by about 80% in comparison to 2.5a2.
236
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000237- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
238 Unicode 4.1.
239
Georg Brandlf4ef1162006-05-26 18:03:31 +0000240- Patch #921466: sys.path_importer_cache is now used to cache valid and
241 invalid file paths for the built-in import machinery which leads to
242 fewer open calls on startup.
243
Tim Peters696cf432006-05-24 21:10:40 +0000244- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
245 of-2 bases. The largest speedup is for inputs with about 1000 decimal
246 digits. Conversion from non-power-of-2 bases remains quadratic-time in
247 the number of input digits (it was and remains linear-time for bases
248 2, 4, 8, 16 and 32).
249
Tim Petersb713ec22006-05-23 18:45:30 +0000250- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
251 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
252 an integer close to ``sys.maxint``. This was repaired by patch
253 #1335972, which also gives a nice speedup.
254
Richard Jonescebbefc2006-05-23 18:28:17 +0000255- Patch #1337051: reduced size of frame objects.
256
257- PyErr_NewException now accepts a tuple of base classes as its
258 "base" parameter.
259
Richard Jones7c88dcc2006-05-23 10:37:38 +0000260- Patch #876206: function call speedup by retaining allocated frame
261 objects.
262
Georg Brandl7b90e162006-05-18 07:01:27 +0000263- Bug #1462152: file() now checks more thoroughly for invalid mode
264 strings and removes a possible "U" before passing the mode to the
265 C library function.
266
Neal Norwitz1004a532006-05-15 07:17:23 +0000267- Patch #1488312, Fix memory alignment problem on SPARC in unicode
268
Neal Norwitz373f0a72006-05-15 07:04:36 +0000269- Bug #1487966: Fix SystemError with conditional expression in assignment
270
Martin v. Löwis879768d2006-05-11 13:28:43 +0000271- WindowsError now has two error code attributes: errno, which carries
272 the error values from errno.h, and winerror, which carries the error
273 values from winerror.h. Previous versions put the winerror.h values
274 (from GetLastError()) into the errno attribute.
275
Martin v. Löwis77736712006-05-04 05:51:03 +0000276- Patch #1475845: Raise IndentationError for unexpected indent.
277
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000278- Patch #1479181: split open() and file() from being aliases for each other.
279
Tim Peters44bd9862006-06-01 13:49:23 +0000280- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
281 methods were always silently ignored by dictionaries when comparing keys.
282 They are now passed through (except when using the C API function
283 ``PyDict_GetItem()``, whose semantics did not change).
284
285- Bug #1456209: In some obscure cases it was possible for a class with a
286 custom ``__eq__()`` method to confuse dict internals when class instances
287 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
288 No, you don't have any code that did this ;-)

294
295- Patch #1462338: Upgrade pyexpat to expat 2.0.0
296
Brett Cannon6ee7d012006-06-08 16:23:04 +0000297- Change binascii.hexlify to accept a read-only buffer instead of only a char
298 buffer and actually follow its documentation.
299
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000300- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
301
Nick Coghlanc649ec52006-05-29 12:43:05 +0000302- Patch #1478788 (modified version): The functional extension module has
303 been renamed to _functools and a functools Python wrapper module added.
304 This provides a home for additional function related utilities that are
305 not specifically about functional programming. See PEP 309.
306
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000307- Patch #1493701: performance enhancements for struct module.

310
Georg Brandl8d3342b2006-05-16 07:38:27 +0000311- Patch #1435422: zlib's compress and decompress objects now have a
312 copy() method.
313
Andrew MacIntyre92913322006-06-13 15:04:24 +0000314- Patch #1454481: thread stack size is now tunable at runtime for thread
315 enabled builds on Windows and systems with Posix threads support.
316
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000317- On Win32, os.listdir now supports arbitrarily-long Unicode path names
318 (up to the system limit of 32K characters).
319
320- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
321 As a result, these functions now raise WindowsError instead of OSError.
322
Tim Peters7a822da2006-05-25 21:50:17 +0000323- ``time.clock()`` on Win64 should use the high-performance Windows
324 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
325 Windows platforms).
326
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000327- Calling Tk_Init twice is refused if the first call failed as that
328 may deadlock.
329
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000330- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
331 accept it without potentially using an uninitialized pointer.
332
333- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
334 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
335 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +0000337- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000338 [pybsddb project SF patch number 1466734]
339
Gregory P. Smith372b5832006-06-05 18:48:21 +0000340- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
341 parameter is supplied. [SF pybsddb bug #1477863]
342
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000343- bsddb: the __len__ method of a DB object has been fixed to return correct
344 results. It could previously incorrectly return 0 in some cases.
345 Fixes SF bug 1493322 (pybsddb bug 1184012).
346
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000347- bsddb: the bsddb.dbtables Modify method now raises the proper error and
348 aborts the db transaction safely when a modifier callback fails.
349 Fixes SF python patch/bug #1408584.
350
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000351- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000352 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000353 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
354 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwisd8251432006-06-14 05:21:04 +0000383- Patch #1455898: The MBCS codec now supports the incremental mode for
384 double-byte encodings.
385
Tim Peters43898b42006-06-14 04:09:25 +0000386- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
387 guarantee that adjacent triples in the return list always describe
388 non-adjacent blocks. Previously, a pair of matching blocks could end
389 up being described by multiple adjacent triples that formed a partition
390 of the matching pair.
391
Greg Ward0e0c9f42006-06-11 16:24:11 +0000392- Bug #1498146: fix optparse to handle Unicode strings in option help,

399
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000400- The wsgiref package has been added to the standard library.
401
Nick Coghlan676725d2006-06-08 13:54:49 +0000402- The functions update_wrapper() and wraps() have been added to the functools
403 module. These make it easier to copy relevant metadata from the original
404 function when writing wrapper functions.
405
Tim Petersd6a9eef2006-06-05 01:48:21 +0000406- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
407 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000408
Martin v. Löwis3f767792006-06-04 19:36:28 +0000409- Patch #1359618: Speed up charmap encoder by using a trie structure
410 for lookup.
411
Tim Petersd609b1a2006-06-02 23:22:51 +0000412- The functions in the ``pprint`` module now sort dictionaries by key
413 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
414 if and only if its display required more than one line, although that
415 wasn't documented. The new behavior increases predictability; e.g.,
416 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
417
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000418- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Georg Brandlb89316f2006-05-17 15:51:16 +0000428- Patch #1180296: Two new functions were added to the locale module:
429 format_string() to get the effect of "format % items" but locale-aware,
430 and currency() to format a monetary number with currency sign.
431
Georg Brandle3a25832006-05-17 14:56:04 +0000432- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

439 stdout arguments, making it possible to redirect input and output
440 for remote debugging.
441
442- Patch #1484695: Update the tarfile module to version 0.8. This fixes
443 a couple of issues, notably handling of long file names using the
444 GNU LONGNAME extension.

490
491*Release date: 27-APR-2006*
492
493Core and builtins
494-----------------
495
Thomas Heller1b046642006-04-18 18:51:06 +0000496- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
497 by converting these apis from macros into exported functions again:
498
499 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
500 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
501 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
502 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
503 PyRun_String Py_CompileString
504
Martin v. Löwis45294a92006-04-18 06:24:08 +0000505- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
506
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000507- All uses of PyStructSequence_InitType have been changed to initialize
508 the type objects only once, even if the interpreter is initialized
509 multiple times.
510
Neal Norwitz61546162006-04-14 05:20:28 +0000511- Bug #1454485, array.array('u') could crash the interpreter. This was
512 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
513 to unicode when it didn't make sense. 'u#' now requires a unicode string.
514
515- Py_UNICODE is unsigned. It was always documented as unsigned, but
516 due to a bug had a signed value in previous versions.
517
Tim Peters3a5e8b12006-04-11 01:44:07 +0000518- Patch #837242: ``id()`` of any Python object always gives a positive
519 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
520 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000521 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000522 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000523
Tim Peters3a5e8b12006-04-11 01:44:07 +0000524 def __hash__(self):
525 return id(self) # WRONG
526
527 because a hash result must be a (short) Python int but it was always
528 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000529 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000530 was always usable as a hash value before this patch. That's no longer
531 necessarily so.
532
533- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000534 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000535 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000536 #1454844)
537
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000538- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
539 involving generators that have paused outside of any ``try`` or ``with``
540 blocks. (In 2.5a1, a paused generator that was part of a reference
541 cycle could not be garbage collected, regardless of whether it was
542 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +0000570- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
571 a doctest to be skipped (the code is not run, and the expected output
572 or exception is ignored).
573
Nick Coghlanda2268f2006-04-24 04:37:15 +0000574- Fixed contextlib.nested to cope with exceptions being raised and

Greg Wardab05edc2006-04-23 03:47:58 +0000577- Updated optparse module to Optik 1.5.1 (allow numeric constants in
578 hex, octal, or binary; add ``append_const`` action; keep going if
579 gettext cannot be imported; added ``OptionParser.destroy()`` method;
580 added ``epilog`` for better help generation).
581
Tim Peters21fbd572006-04-21 21:18:10 +0000582- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
583 called from a thread spawned as a side effect of importing a module.
584
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000585- The pydoc module now supports documenting packages contained in
586 .zip or .egg files.
587
588- The pkgutil module now has several new utility functions, such
589 as ``walk_packages()`` to support working with packages that are either
590 in the filesystem or zip files.
591
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000592- The mailbox module can now modify and delete messages from
593 mailboxes, in addition to simply reading them. Thanks to Gregory
594 K. Johnson for writing the code, and to the 2005 Google Summer of
595 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000596
Tim Petersc7605f22006-04-17 21:12:33 +0000597- The ``__del__`` method of class ``local`` in module ``_threading_local``
598 returned before accomplishing any of its intended cleanup.
599

605
Anthony Baxtere29002c2006-04-12 12:07:31 +0000606- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
607 Windows. Bug #1469163.
608
Phillip J. Eby47032112006-04-11 01:07:43 +0000609- The warnings, linecache, inspect, traceback, site, and doctest modules
610 were updated to work correctly with modules imported from zipfiles or

Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000635 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000636 CXX from --with-cxx-main, see description in README.
637
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000638- Patch #1429775: Link extension modules with the shared libpython.
639
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000640- Fixed a libffi build problem on MIPS systems.
641
Tim Peters8931ff12006-05-13 23:28:20 +0000642- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
643 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
644 and "%zu" for unsigned integers of type ``size_t``.
645
Anthony Baxter51bcb682006-04-05 14:51:42 +0000646Tests
647-----
648
Nick Coghlanda2268f2006-04-24 04:37:15 +0000649- test_contextlib now checks contextlib.nested can cope with exceptions
650 being raised and caught inside exit handlers.
651
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000652- test_cmd_line now checks operation of the -m and -c command switches
653
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000654- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
655 it separately and by hand. It also wasn't cleaning up its changes to
656 the current Decimal context.
657
Thomas Woutersabd08882006-04-26 15:53:30 +0000658- regrtest.py now has a -M option to run tests that test the new limits of
659 containers, on 64-bit architectures. Running these tests is only sensible
660 on 64-bit machines with more than two gigabytes of memory. The argument
661 passed is the maximum amount of memory for the tests to use.
662
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000663Tools

665
666- Added the Python benchmark suite pybench to the Tools/ directory;
667 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000669Documentation
670-------------
671
Tim Petersb06d28c2006-05-12 01:57:59 +0000672- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
673
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000674- PEP 343: Added Context Types section to the library reference
675 and attempted to bring other PEP 343 related documentation into
676 line with the implementation and/or python-dev discussions.
677
Tim Peters8dc73d22006-04-24 02:03:16 +0000678- Bug #1337990: clarified that ``doctest`` does not support examples
679 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000682What's New in Python 2.5 alpha 1?
683=================================
684
Anthony Baxterebed3f62006-04-03 15:03:44 +0000685*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000686
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000687Core and builtins
688-----------------
689
Nick Coghlan43832302006-04-23 17:04:07 +0000690- PEP 338: -m command line switch now delegates to runpy.run_module
691 allowing it to support modules in packages and zipfiles
692
Martin v. Löwisc661b882006-04-20 04:54:23 +0000693- On Windows, .DLL is not an accepted file name extension for
694 extension modules anymore; extensions are only found if they
695 end in .PYD.
696
Martin v. Löwisea62d252006-04-03 10:56:49 +0000697- Bug #1421664: sys.stderr.encoding is now set to the same value as
698 sys.stdout.encoding.
699
Neal Norwitz92e212f2006-04-03 04:48:37 +0000700- __import__ accepts keyword arguments.
701
Georg Brandlccadf842006-03-31 18:54:53 +0000702- Patch #1460496: round() now accepts keyword arguments.
703
Anthony Baxter262c00a2006-03-30 10:53:17 +0000704- Fixed bug #1459029 - unicode reprs were double-escaped.
705
Hye-Shik Changd478f342006-03-23 12:32:36 +0000706- Patch #1396919: The system scope threads are reenabled on FreeBSD
707 5.4 and later versions.
708
Neal Norwitze98ccf62006-03-23 05:39:47 +0000709- Bug #1115379: Compiling a Unicode string with an encoding declaration
710 now gives a SyntaxError.
711
Georg Brandlabd1ff82006-03-18 07:59:59 +0000712- Previously, Python code had no easy way to access the contents of a
713 cell object. Now, a ``cell_contents`` attribute has been added
714 (closes patch #1170323).
715
Tim Peterscf79aac2006-03-16 01:14:46 +0000716- Patch #1123430: Python's small-object allocator now returns an arena to
717 the system ``free()`` when all memory within an arena becomes unused
718 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
719 freed. Some applications will see a drop in virtual memory size now,
720 especially long-running applications that, from time to time, temporarily
721 use a large number of small objects. Note that when Python returns an
722 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000723 platform C library will in turn return that memory to the operating system.
724 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000725 appears to be effective at least on Microsoft C and gcc-based systems.
726 Thanks to Evan Jones for hard work and patience.
727
Georg Brandl533ff6f2006-03-08 18:09:27 +0000728- Patch #1434038: property() now uses the getter's docstring if there is
729 no "doc" argument given. This makes it possible to legitimately use
730 property() as a decorator to produce a read-only property.
731
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000732- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
733 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
734 of requiring an int or long in slicing and a few other contexts, enabling
735 other objects (e.g. Numeric Python's integers) to be used as slice indices.
736
Neal Norwitz995acdf2006-03-07 05:01:00 +0000737- Fixed various bugs reported by Coverity's Prevent tool.
738
Brett Cannonbf364092006-03-01 04:25:17 +0000739- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
740 new exception base class, BaseException, which has a new message attribute.
741 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
742 Raising a string exception now raises a DeprecationWarning.
743
Thomas Woutersfb609f42006-02-28 16:37:25 +0000744- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
745 explicitly relative, using 'from .module import name' to mean 'from the same
746 package as this module is in. Imports without dots still default to the
747 old relative-then-absolute, unless 'from __future__ import
748 absolute_import' is used.
749
Brett Cannona7446e32006-02-27 23:39:10 +0000750- Properly check if 'warnings' raises an exception (usually when a filter set
751 to "error" is triggered) when raising a warning for raising string
752 exceptions.
753
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000754- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000755 The name was removed from Include/code.h.
756
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000757- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000758
Guido van Rossum1968ad32006-02-25 22:38:04 +0000759- Patch 1433928:
760 - The copy module now "copies" function objects (as atomic objects).
761 - dict.__getitem__ now looks for a __missing__ hook before raising
762 KeyError.
763
Tim Peters84ef21c2006-02-28 20:39:06 +0000764- PEP 343: with statement implemented. Needs ``from __future__ import
765 with_statement``. Use of 'with' as a variable will generate a warning.
766 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000767 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000768 The following objects have __context__ methods:
769 - The built-in file type.
770 - The thread.LockType type.
771 - The following types defined by the threading module:
772 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
773 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000774
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000775- Fix the encodings package codec search function to only search
776 inside its own package. Fixes problem reported in patch #1433198.
777
778 Note: Codec packages should implement and register their own
779 codec search function. PEP 100 has the details.
780
Tim Peters9ea89d22006-06-04 03:26:02 +0000781- PEP 353: Using ``Py_ssize_t`` as the index type.
782
783- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
784 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
785 now allow Python to make use of memory blocks exceeding 2**32 bytes for
786 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
787 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000788
Neal Norwitzfc76d632006-01-10 06:03:13 +0000789- Patch #1400181, fix unicode string formatting to not use the locale.
790 This is how string objects work. u'%f' could use , instead of .
791 for the decimal point. Now both strings and unicode always use periods.
792
Neal Norwitz671b9e32006-01-09 07:07:12 +0000793- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
794 configure would break checking curses.h.
795
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000796- Bug #959576: The pwd module is now builtin. This allows Python to be
797 built on UNIX platforms without $HOME set.
798
Neal Norwitzc10978f2005-12-19 06:07:16 +0000799- Bug #1072182, fix some potential problems if characters are signed.
800
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000801- Bug #889500, fix line number on SyntaxWarning for global declarations.
802
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000803- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
804
Neal Norwitze7214a12005-12-18 05:03:17 +0000805- Support for converting hex strings to floats no longer works.
806 This was not portable. float('0x3') now raises a ValueError.
807
Barry Warsaw2a38a862005-12-18 01:27:35 +0000808- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000809 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000810 is now displayed in interactive prompt banner.
811
Georg Brandlfa166682005-12-17 21:45:17 +0000812- Implementation of PEP 341 - Unification of try/except and try/finally.
813 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000814 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000815
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000816- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
817 now encodes backslash correctly.
818
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000819- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
820
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000821- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000822 and long longs.
823
Neal Norwitz67715f02005-11-09 06:59:35 +0000824- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000825 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000826 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000827
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000828- Replaced most Unicode charmap codecs with new ones using the
829 new Unicode translate string feature in the builtin charmap
830 codec; the codecs were created from the mapping tables available
831 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
832 encodings now include a mapping for the Apple logo)
833
Tim Peterse3547fd2005-12-16 23:13:57 +0000834- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000835
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000836- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000837
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000838- A new AST parser implementation was completed. The abstract
839 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000840 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000841
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000842- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000843 The following code now raises a SyntaxError: foo(a = i for i in range(10))
844
Neal Norwitz708e51a2005-10-03 04:48:15 +0000845- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
846
Neal Norwitz11bd1192005-10-03 00:54:56 +0000847- SF Bug #887946: fix segfault when redirecting stdin from a directory.
848 Provide a warning when a directory is passed on the command line.
849
Neal Norwitz40d37812005-10-02 01:48:49 +0000850- Fix segfault with invalid coding.
851
852- SF bug #772896: unknown encoding results in MemoryError.
853
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000854- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000855 supported a __len__() method which evaluated to False when the iterator
856 was empty.
857
Guido van Rossum630db602005-09-20 18:49:54 +0000858- On 64-bit platforms, when __len__() returns a value that cannot be
859 represented as a C int, raise OverflowError.
860
Skip Montanarof8948ca2005-09-19 03:54:46 +0000861- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000862 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000863
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000864- SF bug #893549: parsing keyword arguments was broken with a few format
865 codes.
866
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000867- Changes donated by Elemental Security to make it work on AIX 5.3
868 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
869 bug #105470: test_pwd fails on 64bit system (Opteron).
870
Guido van Rossum539c6622005-09-14 17:49:54 +0000871- Changes donated by Elemental Security to make it work on HP-UX 11 on
872 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
873
Georg Brandl4550b8d2005-08-26 06:43:52 +0000874- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000875 (fixes bug #1119418).
876
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000877- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
878
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000879- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
880 exceptions that cause a function to exit.
881
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000882- The implementation of set() and frozenset() was revised to use its
883 own internal data structure. Memory consumption is reduced by 1/3
884 and there are modest speed-ups as well. The API is unchanged.
885
Tim Petersde7990b2005-07-17 23:45:23 +0000886- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
887
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000888- SF bug #1229429: PyObject_CallMethod failed to decrement some
889 reference counts in some error exit cases.
890
Tim Petersecc6e6a2005-07-10 22:30:55 +0000891- SF bug #1185883: Python's small-object memory allocator took over
892 a block managed by the platform C library whenever a realloc specified
893 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000894 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000895 portable way to copy data from the C-managed block into Python's
896 small-object space without risking a memory fault. Python's small-object
897 realloc now leaves such blocks under the control of the platform C
898 realloc.
899
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000900- SF bug #1232517: An overflow error was not detected properly when
901 attempting to convert a large float to an int in os.utime().
902
Raymond Hettinger3296e692005-06-29 23:29:56 +0000903- SF bug #1224347: hex longs now print with lowercase letters just
904 like their int counterparts.
905
Michael W. Hudson188d4362005-06-20 16:52:57 +0000906- SF bug #1163563: the original fix for bug #1010677 ("thread Module
907 Breaks PyGILState_Ensure()") broke badly in the case of multiple
908 interpreter states; back out that fix and do a better job (see
909 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
910 for a longer write-up of the problem).
911
Michael W. Hudsondf888462005-06-03 14:41:55 +0000912- SF patch #1180995: marshal now uses a binary format by default when
913 serializing floats.
914
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000915- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
916 the routines that promise to produce IEEE 754 binary representations
917 of floats now simply copy bytes around.
918
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000919- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
920 278.
921
Brett Cannonc3647ac2005-04-26 03:45:26 +0000922- patch #1109424: int, long, float, complex, and unicode now check for the
923 proper magic slot for type conversions when subclassed. Previously the
924 magic slot was ignored during conversion. Semantics now match the way
925 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000926 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000927 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000928 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000929
Barry Warsawc8d907c2005-04-19 23:43:40 +0000930- Descriptors defined in C with a PyGetSetDef structure, where the setter is
931 NULL, now raise an AttributeError when attempting to set or delete the
932 attribute. Previously a TypeError was raised, but this was inconsistent
933 with the equivalent pure-Python implementation.
934
Michael W. Hudson774479c2005-04-18 08:46:17 +0000935- It is now safe to call PyGILState_Release() before
936 PyEval_InitThreads() (note that if there is reason to believe there
937 are multiple threads around you still must call PyEval_InitThreads()
938 before using the Python API; this fix is for extension modules that
939 have no way of knowing if Python is multi-threaded yet).
940
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000941- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
942 disabled caused a crash.
943
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000944- Bug #1165306: instancemethod_new allowed the creation of a method
945 with im_class == im_self == NULL, which caused a crash when called.
946
Tim Petersecc6e6a2005-07-10 22:30:55 +0000947- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000948 fixes the crash seen in bug #1165761
949
Raymond Hettinger96229b12005-03-11 06:49:40 +0000950- Added two new builtins, any() and all().
951
Brett Cannon409d8f22005-03-05 06:47:57 +0000952- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000953 (e.g., ``class C(): pass`` is no longer a syntax error).
954 Patch #1176012 added support to the 'parser' module and 'compiler' package
955 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000956
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000957- Patch #1115086: Support PY_LONGLONG in structmember.
958
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000959- Bug #1155938: new style classes did not check that __init__() was
960 returning None.
961
Tim Petersecc6e6a2005-07-10 22:30:55 +0000962- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000963 ('\') with a specific error message.
964
Martin v. Löwisff232d72005-03-03 09:24:38 +0000965- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
966
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000967- Bug #1124295: the __name__ attribute of file objects was
968 inadvertently made inaccessible in restricted mode.
969
Tim Petersecc6e6a2005-07-10 22:30:55 +0000970- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000971 an ferror() call.
972
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000973- min() and max() now support key= arguments with the same meaning as in
974 list.sort().
975
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000976- The peephole optimizer now performs simple constant folding in expressions:
977 (2+3) --> (5).
978
Raymond Hettingera422c342005-01-11 03:03:27 +0000979- set and frozenset objects can now be marshalled. SF #1098985.
980
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000981- Bug #1077106: Poor argument checking could cause memory corruption
982 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000983
Jeremy Hyltonab630502005-02-04 18:44:06 +0000984- The parser did not complain about future statements in illegal
985 positions. It once again reports a syntax error if a future
986 statement occurs after anything other than a doc string.
987
Neil Schemenauercf52c072005-08-12 17:34:58 +0000988- Change the %s format specifier for str objects so that it returns a
989 unicode instance if the argument is not an instance of basestring and
990 calling __str__ on the argument returns a unicode instance.
991
Tim Petersf4e69282006-02-27 17:15:31 +0000992- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
993 current thread state when the auto-GIL-state machinery knows about
994 it (since the thread state is being deleted, continuing to remember it
995 can't help, but can hurt if another thread happens to get created with
996 the same thread id).

1027
Neal Norwitzb62c4332006-03-04 18:35:47 +00001028- The timing module is no longer built by default. It was deprecated

1186-------
1187
Nick Coghlan43832302006-04-23 17:04:07 +00001188- PEP 338: new module runpy defines a run_module function to support
1189 executing modules which provide access to source code or a code object
1190 via the PEP 302 import mechanisms.
1191
Anthony Baxter93f5b932006-04-03 08:05:07 +00001192- The email module's parsedate_tz function now sets the daylight savings
1193 flag to -1 (unknown) since it can't tell from the date whether it should
1194 be set.
1195
Fred Drakead5177c2006-04-01 22:14:43 +00001196- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1197 now sport attributes that provide access to the parts of the result.
1198
Georg Brandl7f6b67c2006-04-01 08:35:18 +00001199- Patch #1462498: sgmllib now handles entity and character references
1200 in attribute values.
1201
Anthony Baxterc51ee692006-04-01 00:57:31 +00001202- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001203 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001204 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001205 module will not be built.
1206
Tim Petersc17976e2006-04-01 00:26:53 +00001207- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1208 aren't officially supported here, and trying to use them will probably
1209 raise an exception some day. But dicts have been allowed, and "mostly
1210 worked", so support for them won't go away without warning.
1211
Georg Brandl338ef7d2006-03-31 18:42:16 +00001212- Bug #1445068: getpass.getpass() can now be given an explicit stream
1213 argument to specify where to write the prompt.
1214
Georg Brandl22ec80b2006-03-31 18:25:44 +00001215- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1217
Neal Norwitz6974a512006-04-10 00:25:01 +00001218- Bug #1250170: mimetools now handles socket.gethostname() failures gracefully.
Georg Brandldd2245f2006-03-31 17:18:06 +00001219
Phillip J. Eby59821cf2006-03-30 02:16:40 +00001220- patch #1457316: "setup.py upload" now supports --identity to select the
1221 key to be used for signing the uploaded code.
1222
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001223- Queue.Queue objects now support .task_done() and .join() methods
1224 to make it easier to monitor when daemon threads have completed
1225 processing all enqueued tasks. Patch #1455676.
1226
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001227- popen2.Popen objects now preserve the command in a .cmd attribute.
1228
Thomas Hellerc61c0492006-03-22 10:09:27 +00001229- Added the ctypes ffi package.
1230
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001231- email 4.0 package now integrated. This is largely the same as the email 3.0
1232 package that was included in Python 2.3, except that PEP 8 module names are
1233 now used (e.g. mail.message instead of email.Message). The MIME classes
1234 have been moved to a subpackage (e.g. email.mime.text instead of
1235 email.MIMEText). The old names are still supported for now. Several
1236 deprecated Message methods have been removed and lots of bugs have been
1237 fixed. More details can be found in the email package documentation.
1238
Walter Dörwald40108c92006-03-27 08:15:44 +00001239- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1240 (a subclass of tuple) that provides incremental decoders and encoders
1241 (a way to use stateful codecs without the stream API). Python functions
1242 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1243 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1244 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001245
Walter Dörwald067db482006-03-15 22:17:27 +00001246- Patch #1359365: Calling next() on a closed StringIO.String object raises
1247 a ValueError instead of a StopIteration now (like file and cString.String do).
1248 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1249 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001250
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001251- A regrtest option -w was added to re-run failed tests in verbose mode.
1252

1254 interpreter to exit.
1255
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001256- The function get_count() has been added to the gc module, and gc.collect()
1257 grew an optional 'generation' argument.
1258
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001259- A library msilib to generate Windows Installer files, and a distutils
1260 command bdist_msi have been added.
1261
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001262- PEP 343: new module contextlib.py defines decorator @contextmanager
1263 and helpful context managers nested() and closing().
1264
Martin v. Löwis415ed932006-02-27 19:56:30 +00001265- The compiler package now supports future imports after the module docstring.
1266
Georg Brandl8f7c54e2006-02-20 08:40:38 +00001267- Bug #1413790: zipfile now sanitizes absolute archive names that are
1268 not allowed by the specs.
1269
Georg Brandlc98eeed2006-02-19 14:57:47 +00001270- Patch #1215184: FileInput now can be given an opening hook which can

1324 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1325 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1326 Ronald L. Rivest offered this advice for Python:
1327
1328 "The consensus of researchers in this area (at least as
1329 expressed at the NIST Hash Function Workshop 10/31/05),
1330 is that SHA-256 is a good choice for the time being, but
1331 that research should continue, and other alternatives may
1332 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001333
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001334- Added a subset of Fredrik Lundh's ElementTree package. Available

Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001447- distutils.commands.register now encodes the data as UTF-8 before posting
1448 them to PyPI.
1449
Raymond Hettinger267b8682005-03-27 10:47:39 +00001450- decimal operator and comparison methods now return NotImplemented
1451 instead of raising a TypeError when interacting with other types. This
1452 allows other classes to implement __radd__ style methods and have them
1453 work as expected.
1454
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001455- Bug #1163325: Decimal infinities failed to hash. Attempting to
1456 hash a NaN raised an InvalidOperation instead of a TypeError.
1457
Tim Petersecc6e6a2005-07-10 22:30:55 +00001458- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001459 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1460
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001461- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00001463- Patch #1075887: Don't require MSVC in distutils if there is nothing
1464 to build.
1465
Martin v. Löwis637431b2005-03-03 23:12:42 +00001466- Patch #1103407: Properly deal with tarfile iterators when untarring
1467 symbolic links on Windows.
1468
Tim Petersecc6e6a2005-07-10 22:30:55 +00001469- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001470 profile.py if available.
1471
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001472- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1473
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001474- Patch #1117454: Remove code to special-case cookies without values
1475 in LWPCookieJar.
1476
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001477- Patch #1117339: Add cookielib special name tests.
1478
Martin v. Löwise869eb12005-03-03 09:46:07 +00001479- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1480
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001481- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1482
Martin v. Löwisdf241532005-03-03 08:17:42 +00001483- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1484
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001485- Patch #1104111: Alter setup.py --help and --help-commands.
1486
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001487- Patch #1121234: Properly cleanup _exit and tkerror commands.
1488
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001489- Patch #1049151: xdrlib now unpacks booleans as True or False.
1490
Raymond Hettingerbab41432005-02-05 01:31:19 +00001491- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1492
Guido van Rossumd0641422005-02-03 15:01:24 +00001493- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1494 disables recursive traversal through instance attributes, which can
1495 be exploited in various ways.
1496
Tim Peterse3547fd2005-12-16 23:13:57 +00001497- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001498 flags on the HTTP listening socket.
1499
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001500- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1501 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1502
Tim Peterse3547fd2005-12-16 23:13:57 +00001503- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001504 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1505
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001506- Bug #1110478: Revert os.environ.update to do putenv again.
1507
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001508- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1509
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001510- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1511
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001512- Enhancements to the csv module:
1513
1514 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001515 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001516 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001517 + Dialect parameter parsing has been re-implemented to improve error
1518 reporting.
1519 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1520 dictates.
1521 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001522 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001523 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001524 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1525 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001526 + reader now allows \r characters to be quoted (previously it only allowed
1527 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001528 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001529 + Dialect classes passed to the module are no longer instantiated by
1530 the module before being parsed (the former validation scheme required
1531 this, but the mechanism was unreliable).
1532 + The dialect registry now contains instances of the internal
1533 C-coded dialect type, rather than references to python objects.
1534 + the internal c-coded dialect type is now immutable.
1535 + register_dialect now accepts the same keyword dialect specifications
1536 as the reader and writer, allowing the user to register dialects
1537 without first creating a dialect class.
1538 + a configurable limit to the size of parsed fields has been added -
1539 previously, an unmatched quote character could result in the entire
1540 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001541 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001542 the parser field size limit (returning the former limit). The initial
1543 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001544 + A line_num attribute has been added to the reader object, which tracks
1545 the number of lines read from the source iterator. This is not
1546 the same as the number of records returned, as records can span
1547 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001548 + reader and writer objects were not being registered with the cyclic-GC.
1549 This has been fixed.
1550
Brett Cannone6539c42005-01-08 02:43:53 +00001551- _DummyThread objects in the threading module now delete self.__block that is
1552 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1553 lock primitives tend to be limited in number and thus should not be wasted on
1554 a _DummyThread object. Fixes bug #1089632.
1555
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001556- The imghdr module now detects Exif files.
1557
Raymond Hettinger6065d322004-12-20 23:51:53 +00001558- StringIO.truncate() now correctly adjusts the size attribute.
1559 (Bug #951915).
1560
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001561- locale.py now uses an updated locale alias table (built using
1562 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1563 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001564 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001565
Raymond Hettinger3557f422004-12-07 12:02:02 +00001566- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1567
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001568- the pickle module no longer accepts the deprecated None option in the
1569 args tuple returned by __reduce__().
1570
Brett Cannon84667c02004-12-07 03:25:18 +00001571- optparse now optionally imports gettext. This allows its use in setup.py.
1572
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001573- the pickle module no longer uses the deprecated bin parameter.
1574
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001575- the shelve module no longer uses the deprecated binary parameter.
1576
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001577- the pstats module no longer uses the deprecated ignore() method.
1578
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001579- the filecmp module no longer uses the deprecated use_statcache argument.
1580
Raymond Hettinger664347b2004-12-04 21:21:53 +00001581- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1582 extended or overridden by subclasses. Formerly, the subclassed method would
1583 be ignored by the rest of the module. (Bug #1078905).
1584
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001585- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001586 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001587
Walter Dörwald36733692004-12-22 12:50:50 +00001588- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1589 once when a size argument is given. This prevents a buffer overflow in the
1590 tokenizer with very long source lines.
1591
Barry Warsaw538561e2006-01-01 21:48:54 +00001592- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1593 immediately after creating the object, without any intervening
1594 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001595
Skip Montanaro05885812005-01-16 20:48:27 +00001596- The reconvert.quote function can now emit triple-quoted strings. The
1597 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001598
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001599- ``UserString.MutableString`` now supports negative indices in
1600 ``__setitem__`` and ``__delitem__``
1601
Greg Ward40407942005-03-05 02:53:17 +00001602- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1603 correctly.
1604
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001605- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1606 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1607 character even if the user has passed a size parameter to get a proper
1608 line ending. Remove the special handling of a "\r\n" that has been split
1609 between two lines.
1610
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001611- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1612 about illegal code points. The codec now supports PEP 293 style error
1613 handlers.
1614
Walter Dörwald78a78b02005-09-01 12:04:29 +00001615- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001616 from the input stream, so that the output is a byte string in the correct
1617 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001618
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001619- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1620 considering it exactly like a '*'.
1621
Walter Dörwald007f8df2005-10-09 19:42:27 +00001622- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1623 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001624
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001625- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1626
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001627- Patch #1413711: Certain patterns of differences were making difflib
1628 touch the recursion limit.
1629
Walter Dörwald58917a62006-03-31 15:26:22 +00001630- Bug #947906: An object oriented interface has been added to the calendar
1631 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001632 called as a script (e.g. via ``python -mcalendar``). Localized month and
1633 weekday names can be ouput (even if an exotic encoding is used) using
1634 special classes that use unicode.

Neal Norwitz602d3392006-03-31 08:21:40 +00001639- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1640 by using -mieee gcc option.
1641
Martin v. Löwis86d66262006-02-17 08:40:11 +00001642- Patch #1432345: Make python compile on DragonFly.
1643
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001644- Build support for Win64-AMD64 was added.
1645
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001646- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1647
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001648- Patch #881820: look for openpty and forkpty also in libbsd.
1649
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001650- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1651 The zlib module is now builtin on Windows.
1652
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001653- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1654
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001655- Bug #1189330: configure did not correctly determine the necessary
1656 value of LINKCC if python was built with GCC 4.0.
1657
Trent Mick8321b422005-07-26 02:29:21 +00001658- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1659 vulnerability in zlib 1.2.1 and 1.2.2.
1660
Brett Cannon08cd5982005-04-24 22:26:38 +00001661- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1662 flags that change binary compatibility. Changes were also made to
1663 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001664 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001665
Bob Ippolitoed233462005-03-29 13:47:59 +00001666- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1667 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1668 no longer exists). This configure patch makes things right.
1669
Martin v. Löwise2713be2005-03-08 15:03:08 +00001670- Bug #1158607: Build with --disable-unicode again.
1671
Brett Cannon46d96232005-02-16 00:07:19 +00001672- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1673 defined. Discovered as a result of not being able to build on OS X.
1674
Brett Cannon516592f2004-12-07 00:42:59 +00001675- setup.py now uses the directories specified in LDFLAGS using the -L option
1676 and in CPPFLAGS using the -I option for adding library and include
1677 directories, respectively, for compiling extension modules against. This has
1678 led to the core being compiled using the values in CPPFLAGS. It also removes
1679 the need for the special-casing of both DarwinPorts and Fink for darwin since
1680 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1681 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1682 Fink, ``-I/opt/local/include`` for DarwinPorts).
1683
Brett Cannon43802422005-02-10 20:48:03 +00001684- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1685 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1686 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1687 Closes bug #1096244. Thanks Gregory Bond.

1690-----
1691
Tim Petersc9d78aa2006-03-26 23:27:58 +00001692- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1693 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1694 is obtained via the ``PyObject_`` family, it must be released via the
1695 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1696 always been officially true, but when Python's small-object allocator was
1697 introduced, an attempt was made to cater to a few extension modules
1698 discovered at the time that obtained memory via ``PyObject_New`` but
1699 released it via ``PyMem_DEL``. It's years later, and if such code still
1700 exists it will fail now (probably with segfaults, but calling wrong
1701 low-level memory management functions can yield many symptoms).
1702
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001703- Added a C API for set and frozenset objects.
1704
Raymond Hettinger66517482004-12-03 11:45:13 +00001705- Removed PyRange_New().

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001707- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1708 mapping argument now. This string is used as a mapping table. Byte values
1709 greater than the length of the string and 0xFFFE are treated as undefined
1710 mappings.
