20 memory usage in some circumstances.
21
Eric Smith0aed07a2008-03-17 19:43:40 +000022- PEP 3127: octal literals now start with "0o". Old-style octal literals
23 are still valid. There are binary literals with a prefix of "0b".
24 This also affects int(x, 0).
25
Jeffrey Yasskin1b4e45b2008-03-17 14:40:53 +000026- Issue #1779871: Gnu gcc can now build Python on OS X because the
27 flags -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd are no
28 longer passed.
29
Neal Norwitz400aeda2008-03-15 22:03:18 +000030- Add a warning when asserting a non-empty tuple which is always true.

39-------
40
Gregory P. Smithf48f9d32008-03-17 18:48:05 +000041- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different values
42 on 32-bit vs. 64-bit python interpreters. Both were correct, but they now
43 both return a signed integer object for consistency.
44
Skip Montanaro32ed8c22008-03-15 16:07:11 +000045- Issue #1158: add %f format (fractions of a second represented as
46 microseconds) to datetime objects. Understood by both strptime and
47 strftime.
48
Mark Dickinsonc23b8a72008-03-14 14:23:37 +000049- Issue #705836: struct.pack(">f", x) now raises OverflowError on all
50 platforms when x is too large to fit into an IEEE 754 float; previously
51 it only raised OverflowError on non IEEE 754 platforms.
52
Facundo Batistac54aec12008-03-08 16:50:27 +000053- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
54 optional: it defaults to the traceback of the exception that is currently
55 being handled (is mandatory to be in the middle of an exception, otherwise
56 it raises ValueError).
57
Jeffrey Yasskine75f59a2008-03-07 06:22:15 +000058- Issue #1193577: A .shutdown() method has been added to SocketServers
59 which terminates the .serve_forever() loop.
60
Georg Brandl98aa8052008-03-06 07:45:52 +000061- Bug #2220: handle rlcompleter attribute match failure more gracefully.
62
Georg Brandla7bd27f2008-03-06 07:41:16 +000063- Issue #2225: py_compile, when executed as a script, now returns a non-
64 zero status code if not all files could be compiled successfully.
65
Georg Brandl810ea292008-03-06 07:34:52 +000066- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
67 root directory, and also exclude .hg, .git, .bzr, and _darcs.
68
Thomas Hellerf3c05592008-03-05 15:34:29 +000069- Issue #1872: The struct module typecode for _Bool has been changed
70 from 't' to '?'.
71
Thomas Heller78b8f442008-03-05 14:53:39 +000072- The bundled libffi copy is now in sync with the recently released
73 libffi3.0.4 version, apart from some small changes to
74 Modules/_ctypes/libffi/configure.ac.
75 On OS X, preconfigured libffi files are used.
76 On all linux systems the --with-system-ffi configure option defaults
77 to "yes".

120
Fred Drakea8ee94b2008-03-01 02:45:07 +0000121- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +0000122 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +0000123
Georg Brandlad61bc82008-02-23 15:11:18 +0000124- Issue #2067: file.__exit__() now calls subclasses' close() method.
125
126- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +0000127
Facundo Batistafc2d0102008-02-23 12:01:13 +0000128- Issue #1881: An internal parser limit has been increased. Also see
129 issue 215555 for a discussion.
130
Eric Smitha73fbe72008-02-23 03:09:44 +0000131- Added the future_builtins module, which contains hex() and oct().
132 These are the PEP 3127 version of these functions, designed to be
133 compatible with the hex() and oct() builtins from Python 3.0. They
134 differ slightly in their output formats from the existing, unchanged
135 Python 2.6 builtins. The expected usage of the future_builtins
136 module is:
137 from future_builtins import hex, oct
138
Eric Smith7ef40bf2008-02-20 23:34:22 +0000139- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
140 exponents for exponents with absolute value < 100. Follows C99
141 standard. This is a change on Windows, which would use 3 digits.
142 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
143 so that any alterations it does to the resulting string will be
144 available in stringlib/formatter.h (for float.__format__).
145
Eric Smith5a3c1352008-02-19 13:21:56 +0000146- Implemented PEP 3101, Advanced String Formatting. This adds a new
147 builtin format(); a format() method for str and unicode; a
148 __format__() method to object, str, unicode, int, long, float, and
149 datetime; the class string.Formatter; and the C API
150 PyObject_Format().
151
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +0000152- Fixed several potential crashes, all caused by specially crafted __del__
153 methods exploiting objects in temporarily inconsistent state.
154
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +0000155- Issue #2115: Important speedup in setting __slot__ attributes. Also
156 prevent a possible crash: an Abstract Base Class would try to access a slot
157 on a registered virtual subclass.
158
Christian Heimes2f0da532008-02-15 06:57:08 +0000159- Fixed repr() and str() of complex numbers with infinity or nan as real or
160 imaginary part.
161
Andrew M. Kuchlingc6511a82008-03-04 01:48:26 +0000162- Clear all free lists during a gc.collect() of the highest generation in order
Christian Heimes3b718a72008-02-14 12:47:33 +0000163 to allow pymalloc to free more arenas. Python may give back memory to the
164 OS earlier.
165
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +0000166- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
167 collections.defaultdict, if its default_factory is set to a bound method.
168
Christian Heimesf75dbef2008-02-08 00:11:31 +0000169- Fixed a minor memory leak in dictobject.c. The content of the free
170 list was not freed on interpreter shutdown.
171
Christian Heimes6075a822008-02-06 12:44:34 +0000172- Limit free list of method and builtin function objects to 256 entries
173 each.
174
Amaury Forgeot d'Arc578a8ca2008-02-04 20:53:14 +0000175- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
176 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +0000177 to compact the internal free lists of pre-allocted ints and floats.
178
Christian Heimes951cc0f2008-01-31 23:08:23 +0000179- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
180 Python expected the return type int but the fork familie returns pi_t.
181
Mark Dickinson105be772008-01-31 22:17:37 +0000182- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
183 in the same code unit.
184
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +0000185- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
186 the collections.Sequence API.
187
Christian Heimes4d4f2702008-01-30 11:32:37 +0000188- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
189 detection
190
Christian Heimes422051a2008-02-04 18:00:12 +0000191- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
Christian Heimes908caac2008-01-27 23:34:59 +0000192 internal lookup cache for ref leak tests.
193
Georg Brandl0cdf9a32008-01-26 14:14:20 +0000194- Patch #1473257: generator objects gain a gi_code attribute. This is the
195 same object as the func_code attribute of the function that produced the
196 generator.
197
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +0000198- Issue #1920: "while 0" statements were completely removed by the compiler,
199 even in the presence of an "else" clause, which is supposed to be run when
200 the condition is false. Now the compiler correctly emits bytecode for the
201 "else" suite.
202
Guido van Rossumeead05f2008-01-24 18:21:02 +0000203- A few crashers fixed: weakref_in_del.py (issue #1377858);
204 loosing_dict_ref.py (issue #1303614, test67.py);
205 borrowed_ref_[34].py (not in tracker).
206
Vinay Sajipd7cf32e2008-01-24 12:43:33 +0000207- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +0000208 suppressed while an extension is loaded by calling SetErrorMode in
209 dynload_win.c. The error is still reported properly.
210
Christian Heimes082c9b02008-01-23 14:20:50 +0000211- Bug #1915: Python compiles with --enable-unicode=no again. However
212 several extension methods and modules do not work without unicode
213 support.
214
Georg Brandl26543b12008-01-21 18:36:51 +0000215- Issue #1882: when compiling code from a string, encoding cookies in the
216 second line of code were not always recognized correctly.
217
Georg Brandl14404b62008-01-19 19:27:05 +0000218- Issue #1679: "0x" was taken as a valid integer literal.
219
Georg Brandl6caad7d2008-01-26 14:19:22 +0000220- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were

222
Christian Heimesc94e2b52008-01-14 04:13:37 +0000223- sys.float_info / PyFloat_GetInfo: The floating point information
224 object was converted from a dict to a specialized structseq object.
225
Christian Heimesf31b69f2008-01-14 03:42:48 +0000226- Patch #1816: Added sys.flags structseq. It exposes the status of most
Vinay Sajip2bdc48c2008-01-21 18:16:05 +0000227 command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +0000228
Georg Brandl6caad7d2008-01-26 14:19:22 +0000229- Objects/structseq.c: Implemented new structseq representation. The patch
Christian Heimesf31b69f2008-01-14 03:42:48 +0000230 makes structseqs (e.g. the return value of os.stat) more readable.
Christian Heimes9c201962008-01-14 03:33:52 +0000231
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +0000232- Patch #1700288: added a type attribute cache that caches method accesses,
233 resulting in speedups in heavily object-oriented code.
234
Neal Norwitz3fc15b82008-01-10 05:42:58 +0000235- Bug #1776: __import__() no longer accepts filenames on any platform.

Christian Heimes3403f152008-01-09 19:56:33 +0000237
Georg Brandlaed6c662008-01-07 17:25:53 +0000238- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
239
Georg Brandl2da0fce2008-01-07 17:09:35 +0000240- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
241 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
242 to attempt to write compiled bytecode files.
243
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +0000244- Improve some exception messages when Windows fails to load an extension
245 module. Now we get for example '%1 is not a valid Win32 application' instead
246 of 'error code 193'.

291
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +0000292- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
293 generator expression when at the same time the executed code is closing a
294 paused generator.
295
Raymond Hettinger1760c8a2007-11-08 02:52:43 +0000296- sets and frozensets now have an isdisjoint() method.
297
Raymond Hettinger3f8caa32007-10-24 01:28:33 +0000298- optimize the performance of builtin.sum().
299
Neal Norwitz44f326e2007-10-05 05:29:17 +0000300- Fix warnings found by the new version of the Coverity checker.
301
Raymond Hettinger8f669372007-10-03 21:18:11 +0000302- The enumerate() builtin function is no longer bounded to sequences smaller
303 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
304 shifts from ints to longs.
305
Brett Cannon0b14f242007-09-30 19:45:10 +0000306- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
307 having a self-referential tuple, which is possible from C code. Nor did
308 object's tp_str consider that a type's tp_str could do something that could
309 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
310 respectively, fixed the issues.
311
Brett Cannon01531592007-09-17 03:28:34 +0000312- Issue #1164: It was possible to trigger deadlock when using the 'print'
313 statement to write to a file since the GIL was not released as needed. Now
314 PyObject_Print() does the right thing along with various tp_print
315 implementations of the built-in types and those in the collections module.
316
Brett Cannon4c20bc42007-09-11 21:02:28 +0000317- Issue #1147: Exceptions were directly allowing string exceptions in their
318 throw() method even though string exceptions no longer allowed.
319
Brett Cannona0c05512007-09-10 21:38:27 +0000320- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
321 list by using the recursion counter.
322
Brett Cannon1e534b52007-09-07 04:18:30 +0000323- Issue #1202533: Fix infinite recursion calls triggered by calls to
324 PyObject_Call() never calling back out to Python code to trigger recursion
325 depth updates/checks. Required the creation of a static RuntimeError
326 instance in case normalizing an exception put the recursion check value past
327 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
328
Martin v. Löwisa5136192007-09-04 14:19:28 +0000329- Patch #1031213: Decode source line in SyntaxErrors back to its original source
330 encoding.
331
Georg Brandl7c3b50d2007-07-12 08:38:00 +0000332- Patch #1673759: add a missing overflow check when formatting floats
333 with %G.
334
Neal Norwitzdb2b1b32007-06-11 07:36:24 +0000335- Prevent expandtabs() on string and unicode objects from causing a segfault
336 when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +0000337
Martin v. Löwisda587ab2007-06-08 17:29:20 +0000338- Bug #1733488: Fix compilation of bufferobject.c on AIX.
339

Georg Brandla5ea6892007-06-01 11:33:33 +0000341
Neal Norwitz0ac60192007-05-27 04:08:54 +0000342- Add new attribute names for function objects. All the func_* become
343 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
344
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +0000345- Add -3 option to the interpreter to warn about features that are
346 deprecated and will be changed/removed in Python 3.0.
347
Georg Brandl2134e752007-05-21 20:34:16 +0000348- Patch #1686487: you can now pass any mapping after '**' in function
349 calls.
350
Collin Winter62903052007-05-18 23:11:24 +0000351- except clauses may now be spelled either "except E, target:" or
352 "except E as target:". This is to provide forwards compatibility with
353 Python 3.0.
354
Brett Cannon229cee22007-05-05 01:34:02 +0000355- Deprecate BaseException.message as per PEP 352.
356
Armin Rigo9790a272007-05-02 19:23:31 +0000357- Bug #1303614: don't expose object's __dict__ when the dict is
358 inherited from a builtin base.
359
Vinay Sajip8549ce32007-05-06 17:53:37 +0000360- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +0000361 setting a plain string, ie don't expand to single letter identifiers.
362
Raymond Hettinger13936692007-04-11 18:40:58 +0000363- Request #1191699: Slices can now be pickled.
364
Raymond Hettinger4db5fe92007-04-12 04:10:00 +0000365- Request #1193128: str.translate() now allows a None argument for
366 translations that only remove characters without re-mapping the
367 remaining characters.
368
Georg Brandl5cb76c12007-03-21 09:00:39 +0000369- Patch #1682205: a TypeError while unpacking an iterable is no longer
370 masked by a generic one with the message "unpack non-sequence".
371
Neal Norwitzaa754b72007-03-21 06:39:48 +0000372- Remove unused file Python/fmod.c.
373
Guido van Rossum143b5642007-03-23 04:58:42 +0000374- Bug #1683368: The object.__init__() and object.__new__() methods are
375 now stricter in rejecting excess arguments. The only time when
376 either allows excess arguments is when it is not overridden and the
377 other one is. For backwards compatibility, when both are
378 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +0000379 warning later). Also, type.__init__() insists on the same signature
380 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +0000381
Georg Brandl2b869942007-03-17 16:08:45 +0000382- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
383 to complex using its __complex__() method before falling back to the
384 __float__() method. Therefore, the functions in the cmath module now
385 can operate on objects that define a __complex__() method.
386
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +0000387- Patch #1623563: allow __class__ assignment for classes with __slots__.
388 The old and the new class are still required to have the same slot names.
389
Collin Winter77c67bd2007-03-16 04:11:30 +0000390- Patch #1642547: Fix an error/crash when encountering syntax errors in
391 complex if statements.
392
Žiga Seilnacht20f43d32007-03-15 11:44:55 +0000393- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
394 is called with an object that is faking its type.
395
Žiga Seilnacht71436f02007-03-14 12:24:09 +0000396- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
397 name.
398
Georg Brandl5240d742007-03-13 20:46:32 +0000399- Patch #1444529: the builtin compile() now accepts keyword arguments.
400
Georg Brandl7b9c5552007-03-12 14:30:05 +0000401- Bug #1678647: write a newline after printing an exception in any
402 case, even when converting the value to a string failed.
403
Georg Brandl871f1bc2007-03-12 13:17:36 +0000404- The dir() function has been extended to call the __dir__() method on
405 its argument, if it exists. If not, it will work like before. This allows
406 customizing the output of dir() in the presence of a __getattr__().
407
Collin Winter276887b2007-03-12 16:11:39 +0000408- Patch #922167: Python no longer segfaults when faced with infinitely
409 self-recursive reload() calls (as reported by bug #742342).
410
Žiga Seilnacht89032082007-03-11 15:54:54 +0000411- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
412
Collin Wintere38051d2007-03-09 20:33:07 +0000413- Patch #1491866: change the complex() constructor to allow parthensized
414 forms. This means complex(repr(x)) now works instead of raising a
415 ValueError.
416
Georg Brandlaa2321b2007-03-07 00:40:28 +0000417- Patch #703779: unset __file__ in __main__ after running a file. This
418 makes the filenames the warning module prints much more sensible when
419 a PYTHONSTARTUP file is used.
420
Georg Brandl49aafc92007-03-07 00:34:46 +0000421- Variant of patch #697613: don't exit the interpreter on a SystemExit
422 exception if the -i command line option or PYTHONINSPECT environment
423 variable is given, but break into the interactive interpreter just like
424 on other exceptions or normal program exit.
425
Georg Brandl00cd8182007-03-06 18:41:12 +0000426- Patch #1638879: don't accept strings with embedded NUL bytes in long().
427
Georg Brandl098cd692007-03-06 12:17:50 +0000428- Bug #1674503: close the file opened by execfile() in an error condition.
429
Georg Brandl0fca97a2007-03-05 22:28:08 +0000430- Patch #1674228: when assigning a slice (old-style), check for the
431 sq_ass_slice instead of the sq_slice slot.
432
Neal Norwitz88516a62007-02-26 22:41:45 +0000433- When printing an unraisable error, don't print exceptions. before the name.
434 This duplicates the behavior whening normally printing exceptions.
435
Martin v. Löwisfd963262007-02-09 12:19:32 +0000436- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
437
Brett Cannon129bd522007-01-30 21:34:36 +0000438- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
439 catch a string exception raises DeprecationWarning.
440
Brett Cannonf5bee302007-01-23 23:21:22 +0000441- Bug #1377858: Fix the segfaulting of the interpreter when an object created
442 a weakref on itself during a __del__ call for new-style classes (classic
443 classes still have the bug).
444
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000445- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
446 frame's thread state.
447
Thomas Wouters6ed19652007-01-23 13:50:49 +0000448- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
449
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000450- Prevent seg fault on shutdown which could occur if an object
451 raised a warning.
452
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000453- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
454 to avoid relying on atexit.
455
Raymond Hettinger94547f72006-12-20 06:42:06 +0000456- Bug #1590891: random.randrange don't return correct value for big number
457
Georg Brandl283a1352006-11-19 08:48:30 +0000458- Patch #1586791: Better exception messages for some operations on strings,
459 tuples and lists.

Neal Norwitz85dbec62006-11-04 19:25:22 +0000465- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
466
Georg Brandlb9f4ad32006-10-29 18:31:42 +0000467- Bug #1576657: when setting a KeyError for a tuple key, make sure that
468 the tuple isn't used as the "exception arguments tuple".
469
Neal Norwitz21997af2006-10-28 21:19:07 +0000470- Bug #1565514, SystemError not raised on too many nested blocks.
471
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000472- Bug #1576174: WindowsError now displays the windows error code
473 again, no longer the posix error code.
474
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000475- Patch #1549049: Support long values in structmember, issue warnings
476 if the assigned value for structmember fields gets truncated.
477
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000478- Update the peephole optimizer to remove more dead code (jumps after returns)
479 and inline unconditional jumps to returns.
480
Georg Brandl2c1375c2006-10-12 11:27:59 +0000481- Bug #1545497: when given an explicit base, int() did ignore NULs
482 embedded in the string to convert.
483
Georg Brandl846f73a2006-10-08 07:11:54 +0000484- Bug #1569998: break inside a try statement (outside a loop) is now
485 recognized and rejected.
486
Armin Rigo7ccbca92006-10-04 12:17:45 +0000487- list.pop(x) accepts any object x following the __index__ protocol.
488
Armin Rigo7ccbca92006-10-04 12:17:45 +0000489- A number of places, including integer negation and absolute value,
490 were fixed to not rely on undefined behaviour of the C compiler
491 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000492
Georg Brandl3267d282006-09-30 09:03:42 +0000493- Bug #1566800: make sure that EnvironmentError can be called with any
494 number of arguments, as was the case in Python 2.4.
495
Georg Brandl5d59c092006-09-30 08:43:30 +0000496- Patch #1567691: super() and new.instancemethod() now don't accept
497 keyword arguments any more (previously they accepted them, but didn't
498 use them).
499
Georg Brandla10d3af2006-09-24 12:35:36 +0000500- Fix a bug in the parser's future statement handling that led to "with"
501 not being recognized as a keyword after, e.g., this statement:
502 from __future__ import division, with_statement
503
Neal Norwitz3a230172006-09-22 08:18:10 +0000504- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

507
Brett Cannonf6aa86e2006-09-20 18:43:13 +0000508- Allow exception instances to be directly sliced again.
509
Brett Cannon9adeab72006-09-20 18:34:28 +0000510- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
511 allows calling unicode() on exceptions classes directly to succeed.
512
Georg Brandl4e933132006-09-06 20:05:58 +0000513- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
514 Also make sure that every exception class has __module__ set to
515 'exceptions'.
516
Georg Brandl98775df2006-09-06 06:09:31 +0000517- Bug #1550983: emit better error messages for erroneous relative
518 imports (if not in package and if beyond toplevel package).
519
Tim Petersc10c9d02006-09-05 02:18:09 +0000520- Overflow checking code in integer division ran afoul of new gcc
521 optimizations. Changed to be more standard-conforming.
522
Neal Norwitz4f096d92006-08-21 19:47:08 +0000523- Patch #1542451: disallow continue anywhere under a finally.

526
Neal Norwitzd34e4272006-09-05 02:36:20 +0000527- The return tuple from str.rpartition(sep) is (tail, sep, head) where
528 head is the original string if sep was not found.
529
Neal Norwitzdac090d2006-09-05 03:53:08 +0000530- Bug #1520864: unpacking singleton tuples in list comprehensions and
531 generator expressions (x for x, in ... ) works again. Fixing this problem
532 required changing the .pyc magic number. This means that .pyc files
533 generated before 2.5c2 will be regenerated.
534
Georg Brandl6caad7d2008-01-26 14:19:22 +0000535- ``with`` and ``as`` are now keywords.
Neal Norwitzca460d92006-09-06 06:28:06 +0000536
Jeremy Hyltonc5ceb252007-02-25 15:57:45 +0000537- Bug #1664966: Fix crash in exec if Unicode filename can't be decoded.

Guido van Rossumcad37242008-01-15 17:59:29 +0000539- Issue #1537: Changed GeneratorExit's base class from Exception to
540 BaseException.
Christian Heimes44eeaec2007-12-03 20:01:02 +0000541
Gregory P. Smith95cd5c02008-01-22 01:20:42 +0000542- Fix Issue #1703448: A joined thread could show up in the
543 threading.enumerate() list after the join() for a brief period until
544 it actually exited.

562 of raising ValueError.
563
Georg Brandl16479232008-02-23 15:02:28 +0000564- #1492: The content type of BaseHTTPServer error messages can now be

566
Facundo Batistab12f0b52008-02-23 12:46:10 +0000567- Issue 1781: ConfigParser now does not let you add the "default" section
568 (ignore-case)
569
Guido van Rossum8bc09652008-02-21 18:18:37 +0000570- Removed uses of dict.has_key() from distutils, and uses of
571 callable() from copy_reg.py, so the interpreter now starts up
572 without warnings when '-3' is given. More work like this needs to
573 be done in the rest of the stdlib.
574
Facundo Batista759bfc62008-02-18 03:43:43 +0000575- Issue #1916. Added isgenerator() and isgeneratorfunction() to inspect.py.

881
Georg Brandla09a96a2007-05-15 20:19:34 +0000882- HTML-escape the plain traceback in cgitb's HTML output, to prevent
883 the traceback inadvertently or maliciously closing the comment and
884 injecting HTML into the error page.
885
Neal Norwitz42dd86b2007-05-11 06:57:33 +0000886- The popen2 module and os.popen* are deprecated. Use the subprocess module.

Facundo Batistad918a652007-04-24 13:54:38 +0000903- As specified in RFC 2616, an HTTP response like 2xx indicates that
904 the client's request was successfully received, understood, and accepted.

Facundo Batista07c78be2007-03-23 18:54:07 +0000920
Martin v. Löwis0af33882007-03-23 13:27:15 +0000921- Bug #978833: Revert r50844, as it broke _socketobject.dup.

930 directories.
931

933 GNOME or KDE browser, depending on whether there is a session of one
934 of those present. Also, it tries the Windows default browser before

941
Georg Brandlf66b6032007-03-14 08:27:52 +0000942- Bug #767111: fix long-standing bug in urllib which caused an

945
Georg Brandl03b90d82007-03-13 22:07:36 +0000946- Patch #957650: "%var%" environment variable references are now properly

960
Georg Brandl8441f152007-03-13 20:02:57 +0000961- Patch #1530482: add pydoc.render_doc() which returns the documentation
962 for a thing instead of paging it to stdout, which pydoc.doc() does.
963
Georg Brandld9bef352007-03-13 19:32:21 +0000964- Patch #1533909: the timeit module now accepts callables in addition to

Collin Winterfaaa2042007-03-10 03:35:34 +00001008 be equal to calling getsockname() on the server's socket. Fixed by
1009 patch #1545011.
Collin Winter22c42ba2007-03-10 02:51:26 +00001010
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00001011- Patch #742598: Add .timeout attribute to SocketServer that calls

1018 returned string up to the first NUL character.

1029
Georg Brandl9caadf82007-03-08 18:37:31 +00001030- unittest now verifies more of its assumptions. In particular, TestCase
1031 and TestSuite subclasses (not instances) are no longer accepted in
1032 TestSuite.addTest(). This should cause no incompatibility since it

1034 later, with a more cumbersome exception.
1035

1065 import semantics.

1079 relative directory names.
1080

1305
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001306- Issue829951: In the smtplib module, SMTP.starttls() now complies with
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00001307 RFC 3207 and forgets any knowledge obtained from the server not obtained
1308 from the TLS negotiation itself. Patch contributed by Bill Fenner.
1309
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00001310- Issue1339: The smtplib.SMTP class has been refactored a bit such
1311 that the SMTP.starttls() caller no longer needs to call ehlo()

1314 method. Patch contributed by Bill Fenner.

1386 tuple, list, dict, set, and frozenset. Formerly, it would silently miscode

1403 time so that opening a database previously created with the DB_DUP or
1404 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1405 Specifically: dictionary assignment to a DB object will replace all
1406 values for a given key when the database allows duplicate values.
1407 DB users should use DB.put(k, v) when they want to store duplicates; not
1408 DB[k] = v.
1409
Gregory P. Smithac11e022007-11-05 02:56:31 +00001410- Add the bsddb.db.DBEnv.lock_id_free method.

1417 quoting dots if they are the second character of any line.
1418
Georg Brandla47337f2007-03-13 12:34:25 +00001419- Bug #1622896: fix a rare corner case where the bz2 module raised an

1728-----
1729
Christian Heimes5b970ad2008-02-06 13:33:44 +00001730- Unified naming convention for free lists and their limits. All free lists
1731 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
1732 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
1733
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00001734- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
1735 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
1736 it does not steal a reference to the added item.
1737
1738- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
1739
Georg Brandl6caad7d2008-01-26 14:19:22 +00001740- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
1741 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t
1742 public functions.
1743
1744- Patch #1720595: add T_BOOL to the range of structmember types.
1745
1746- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
1747 ``PyFloat_GetInfo()`` to the float API.
1748
1749- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
1750 format code incorrectly truncated the length to an int, even when
1751 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
1752 results with huge strings.
1753
1754- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
1755 and Py_REFCNT.
1756
1757- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
1758 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
1759 PyVarObject_HEAD_INIT.
1760
1761- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
1762
1763- Patch #1733960: Allow T_LONGLONG to accept ints.
1764
1765- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
1766
Christian Heimes000a0742008-01-03 22:16:32 +00001767- Added a new API function ``PyImport_ImportModuleNoBlock``.
1768
Georg Brandl6caad7d2008-01-26 14:19:22 +00001769- Bug #1637022: Prefix AST symbols with _Py_.
1770
1771- Fix some leftovers from the conversion from int to Py_ssize_t
1772 (relevant to strings and sequences of more than 2**31 items).
1773
1774- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1775 outside of pystate.c and should not be necessary.
1776
Christian Heimes000a0742008-01-03 22:16:32 +00001777- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
1778 imports. In earlier versions they might have used relative imports under
1779 some conditions.
1780
Andrew M. Kuchlingadc60ab2008-01-04 02:26:00 +00001781- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
Christian Heimes000a0742008-01-03 22:16:32 +00001782 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
1783
Neal Norwitz8a267062006-08-19 04:25:29 +00001784- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
1785 so it can be used as an expression.

1790
Christian Heimes95d64472008-02-09 19:55:22 +00001791- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
1792 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
1793 Win2k for x86/32bit builds and WinXP for AMD64 builds.
1794
Martin v. Löwis2607e6c2006-11-21 18:20:25 +00001795- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
1796 and _CRT_NONSTDC_NO_DEPRECATE.
1797

1807
Brett Cannon5e263512007-05-20 23:17:38 +00001808- Removed the macfs module. It had been deprecated since Python 2.5. This
1809 lead to the deprecation of macostools.touched() as it relied solely on macfs
1810 and was a no-op under OS X.
