7 What's New in Python 2.6 beta 1?
8 ================================
10 *Release date: XX-June-2008*
15 - Issue #2801: fix bug in the float.is_integer method where a ValueError
16 was sometimes incorrectly raised.
18 - Issue #2790: sys.flags was not properly exposing its bytes_warning attribute.
26 - The Canvas module has been deprecated for removal in Python 3.0.

32 - The bsddb185 module has been deprecated for removal in Python 3.0.
34 - The pure module has been deprecated for removal in Python 3.0.
36 - Issue #2487: change the semantics of math.ldexp(x, n) when n is too
37 large to fit in a C long. ldexp(x, n) now returns a zero (with
38 suitable sign) if n is large and negative; previously, it raised
41 - The toaiff module has been deprecated for removal in Python 3.0.
43 - The test.testall module has been deprecated for removal in Python 3.0.

51 - The mutex module has been deprecated for removal in Python 3.0.
53 - The imputil module has been deprecated for removal in Python 3.0.
55 - test.test_support.catch_warning() gained a 'record' argument.
57 - os.path.walk is deprecated in favor of os.walk.
62 What's New in Python 2.6 alpha 3?
63 =================================
65 *Release date: 08-May-2008*
70 - Issue #2719: backported the ``next()`` builtin from Python 3.
72 - Issue #2681: The octal literal ``0o8`` was incorrecly acctepted. Now it
73 properly raises a SyntaxError.
75 - Patch #2617: Reserved -J and -X arguments for Jython, IronPython and other
76 implementations of Python.
78 - Implemented PEP 370: Per user site-packages directory
83 - Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
84 handlers that derive the same default base class.
86 - Added kill, terminate and send_signal(sig) to subprocess.Popen.
88 - Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to the cmath
91 - Four new methods were added to the math and cmath modules:
92 acosh, asinh, atanh and log1p.
94 - zlib.decompressobj().flush(value) no longer crashes the interpreter when
95 passed a value less than or equal to zero.
97 - Issue #1631171: Re-implement the 'warnings' module in C (the original Python
98 code has been kept as backup). This will allow for using the 'warning's
99 machinery in such places as the parser where use of pure Python code is not
100 possible. Both the ``showarning()`` and ``formatwarning()`` gain an
101 optional 'line' argument which is not called by default for
102 backwards-compatibility reasons. Setting ``warnings.showwarning()`` to
103 an implementation that lacks support for the ``line`` argument will raise a
109 - The audiodev module has been deprecated for removal in Python 3.0.
111 - Issue #2750: Add the 'json' package. Based on simplejson 1.9 and contributed
114 - Issue #1734346: Support Unicode file names for zipfiles.
116 - Issue #2581: distutils: Vista UAC/elevation support for bdist_wininst
118 - Issue #2635: Fix bug in 'fix_sentence_endings' textwrap.fill option,
119 where an extra space was added after a word containing (but not
120 ending in) '.', '!' or '?'.
122 - Add from_buffer() and from_buffer_copy() class methods to ctypes
125 - Issue #2682: ctypes callback functions no longer contain a cyclic
126 reference to themselves.
128 - The getpass module has been improved on Unix. It now uses /dev/tty
129 by default and uses stderr instead of stdout. A GetPassWarning is
130 issued when input echo cannot be controlled.
132 - Issue #2014: Allow XML-RPC datetime objects to have dates before
135 - Issue #2439: Added new function pkgutil.get_data(), which is a
136 convenience wrapper for the PEP 302 get_data() API.
138 - Issue #2616: The ctypes.pointer() and ctypes.POINTER() functions are
139 now implemented in C for better performance.
141 - Issue #2408: The ``_types`` module, which was used as in implementation
142 detail of the public ``types`` module, has been removed and replaced by pure
145 - Issue #2513: distutils on Windows is now capable of cross-compiling
146 extension modules between 32 and 64 bit platforms. See the distutls
147 build documentation for more information.
149 - Issue #815646: Individual file objects may now be used from multiple
150 threads at once without fear of crashing the Python interpreter. If
151 file.close() is called while an object is in use by another thread
152 an IOError exception will be raised and the file will not be closed.
154 - The bundled libffi copy is now in sync with the recently released
155 libffi3.0.5 version, apart from some small changes to
156 Modules/_ctypes/libffi/configure.ac.
158 - Issue #2385: distutils.core.run_script() makes __file__ available, so the
159 controlled environment will more closely mirror the typical script
160 environment. This supports setup.py scripts that refer to data files.
164 - Issue #2550: The approach used by client/server code for obtaining ports
165 to listen on in network-oriented tests has been refined in an effort to
166 facilitate running multiple instances of the entire regression test suite
167 in parallel without issue. test_support.bind_port() has been fixed such
168 that it will always return a unique port -- which wasn't always the case
169 with the previous implementation, especially if socket options had been
170 set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
171 new implementation of bind_port() will actually raise an exception if it
172 is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
173 SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
174 will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
175 This currently only applies to Windows. This option prevents any other
176 sockets from binding to the host/port we've bound to, thus removing the
177 possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
178 that occurs when a second SOCK_STREAM socket binds and accepts to a
179 host/port that's already been bound by another socket. The optional
180 preferred port parameter to bind_port() has been removed. Under no
181 circumstances should tests be hard coding ports!
183 test_support.find_unused_port() has also been introduced, which will pass
184 a temporary socket object to bind_port() in order to obtain an unused port.
185 The temporary socket object is then closed and deleted, and the port is
186 returned. This method should only be used for obtaining an unused port
187 in order to pass to an external program (i.e. the -accept [port] argument
188 to openssl's s_server mode) or as a parameter to a server-oriented class
189 that doesn't give you direct access to the underlying socket used.
191 Finally, test_support.HOST has been introduced, which should be used for
192 the host argument of any relevant socket calls (i.e. bind and connect).
194 The following tests were updated to following the new conventions:
195 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
196 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
197 test_asynchat and test_socket_ssl.
199 It is now possible for multiple instances of the regression test suite to
200 run in parallel without issue.
205 - Issue #1496032: On alpha, use -mieee when gcc is the compiler.
207 - Issue #2544: On HP-UX systems, use 'gcc -shared' for linking when
208 gcc is used as compiler.
210 - Issue #2573: On MacOS X it is now possible to install the framework
211 with a different name using --with-framework-name=NAME.
216 - Added implementation of copysign, acosh, asinh, atanh and log1p
217 to the new files Include/pymath.h and Python/pymath.h for
218 platforms which provide the functions through their libm. The
219 files also contains several helpers and constants for math.
221 - Added a new convenience function, PyErr_WarnPy3k, for issuing Py3k
225 What's New in Python 2.6 alpha 2?
226 =================================
228 *Release date: 02-Apr-2008*
233 - Issue #1733757: The interpreter would hang on shutdown if the tracing
234 function set by sys.settrace is still active and happens to call
235 threading.currentThread().
237 - Patch #1442: properly report exceptions when the PYTHONSTARTUP file
240 - The compilation of a class nested in another class used to leak one
241 reference on the outer class name.
243 - Patch #1810: compile() can now compile _ast trees as returned by
244 compile(..., PyCF_ONLY_AST).
246 - Patch #2426: Added sqlite3.Connection.iterdump method to allow easy dumping
247 of databases. Contributed by Paul Kippes at PyCon 2008.
249 - Patch #2477: Added from __future__ import unicode_literals.
251 - Added backport of bytearray type.
253 - Issue #2355: add Py3k warning for buffer().
255 - Issue #1477: With narrow Unicode builds, the unicode escape sequence
256 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
257 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
258 UTF-16 surrogates are generated in this case, like normal unicode literals
259 and the 'unicode-escape' codec.
261 - Issue #2348: add Py3k warning for file.softspace.
263 - Issue #2346/#2347: add Py3k warnings for __methods__ and __members__.

273 The two changes are: im_self -> __self__ and im_func -> __func__
275 - Issue 2379: Raise a Py3K warning for __getitem__ or __getslice__ on
278 - Issue #2371: Add a Py3k warning when catching an exception that
279 doesn't derive from BaseException. Issue #2341: Add a Py3k warning
280 when raising an exception that doesn't derive from BaseException.
282 - Issue #2321: use pymalloc for unicode object string data to reduce
283 memory usage in some circumstances.
285 - PEP 3127: octal literals now start with "0o". Old-style octal literals
286 are still valid. There are binary literals with a prefix of "0b".
287 This also affects int(x, 0).
289 - Issue #2359: Adding deprecation warnings for array.{read,write}.
291 - Issue #1779871: Gnu gcc can now build Python on OS X because the
292 flags -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd are no
295 - Add a warning when asserting a non-empty tuple which is always true.
297 - Issue #2179: speed up with statement execution by storing the exit method
298 on the stack instead of in a temporary variable (patch by Jeffrey Yaskin)
300 - Issue #2238: Some syntax errors in *args and **kwargs expressions could give
301 bogus error messages.
303 - Issue #2143: Fix embedded readline() hang on SSL socket EOF.
308 - Patch #2240: Implement signal.setitimer and signal.getitimer.
313 - Issue #2315: logging.handlers: TimedRotatingFileHandler now accounts for
314 daylight savings time in calculating the next rollover.
316 - Issue #2316: logging.handlers: TimedRotatingFileHandler now calculates
317 rollovers correctly even when nothing is logged for a while.
319 - Issue #2317: logging.handlers: TimedRotatingFileHandler now uses improved
320 logic for removing old files.
322 - Issue #2495: tokenize.untokenize now inserts a space between two consecutive
323 string literals; previously, ["" ""] was rendered as [""""], which is
324 incorrect python code.
326 - Issue #2248: return the result of the QUIT command. from SMTP.quit().
328 - Backport of Python 3.0's io module.
330 - Issue #2482: Make sure that the coefficient of a Decimal is always
331 stored as a str instance, not as a unicode instance. This ensures
332 that str(Decimal) is always an instance of str.
334 - Issue #2478: fix failure of decimal.Decimal(0).sqrt()
336 - Issue #2432: give DictReader the dialect and line_num attributes
337 advertised in the docs.
339 - Issue #2460: Make Ellipsis object copyable.
341 - Issue #1681432: Add triangular distribution to the random module

344 WWW-Authenticate header.
346 - Issue #2434: Enhanced platform.win32_ver() to also work on Python
347 installation which do not have the win32all package installed.
349 - Added support to platform.uname() to also report the machine
350 and processor information on Windows XP and later. As a result,
351 platform.machine() and platform.processor() will report this

355 to the standard distribution.
357 - Issue #1747858: Fix chown to work with large uid's and gid's on 64-bit
360 - Issue #1202: zlib.crc32 and zlib.adler32 no longer return different values
361 on 32-bit vs. 64-bit python interpreters. Both were correct, but they now
362 both return a signed integer object for consistency.
364 - Issue #1158: add %f format (fractions of a second represented as
365 microseconds) to datetime objects. Understood by both strptime and
368 - Issue #705836: struct.pack(">f", x) now raises OverflowError on all
369 platforms when x is too large to fit into an IEEE 754 float; previously
370 it only raised OverflowError on non IEEE 754 platforms.
372 - Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
373 optional: it defaults to the traceback of the exception that is currently
374 being handled (is mandatory to be in the middle of an exception, otherwise
375 it raises ValueError).
377 - Issue #1193577: A .shutdown() method has been added to SocketServers
378 which terminates the .serve_forever() loop.
380 - Bug #2220: handle rlcompleter attribute match failure more gracefully.

385 - Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
386 root directory, and also exclude .hg, .git, .bzr, and _darcs.
388 - Issue #1872: The struct module typecode for _Bool has been changed
391 - The bundled libffi copy is now in sync with the recently released
392 libffi3.0.4 version, apart from some small changes to
393 Modules/_ctypes/libffi/configure.ac.
394 On OS X, preconfigured libffi files are used.
395 On all linux systems the --with-system-ffi configure option defaults
398 - Issue 1577: shutil.move() now calls os.rename() if the destination is a
399 directory instead of copying-then-remove-source.
404 - test_nis no longer fails when test.test_support.verbose is true and NIS is
405 not set up on the testing machine.
407 - Output comparison tests are no longer supported.
409 - Rewrite test_errno to use unittest and no longer be a no-op.
411 - GHOP 234: Convert test_extcall to doctest.
413 - GHOP 290: Convert test_dbm and test_dummy_threading to unittest.
415 - GHOP 293: Convert test_strftime, test_getargs, and test_pep247 to unittest.

421 - GHOP 294: Convert test_contains, test_crypt, and test_select to unittest.
423 - GHOP 238: Convert test_tokenize to use doctest.
425 - GHOP 237: Rewrite test_thread using unittest.
427 - Patch #2232: os.tmpfile might fail on Windows if the user has no
428 permission to create files in the root directory.
433 - A new script 2to3 is now installed, to run the 2.x to 3.x converter.
435 - Python/memmove.c and Python/strerror.c have been removed; both functions are
436 in the C89 standard library.
438 - Patch #2284: Add -x64 option to rt.bat.
443 - Patch #2477: Added PyParser_ParseFileFlagsEx() and

446 What's New in Python 2.6 alpha 1?
447 =================================
449 *Release date: 29-Feb-2008*
454 - Issue #2051: pyc and pyo files are no longer created with permission
455 644. The mode is now inherited from the py file.
457 - Issue #2067: file.__exit__() now calls subclasses' close() method.
459 - Patch #1759: Backport of PEP 3129 class decorators.
461 - Issue #1881: An internal parser limit has been increased. Also see
462 issue 215555 for a discussion.
464 - Added the future_builtins module, which contains hex() and oct().
465 These are the PEP 3127 version of these functions, designed to be
466 compatible with the hex() and oct() builtins from Python 3.0. They
467 differ slightly in their output formats from the existing, unchanged
468 Python 2.6 builtins. The expected usage of the future_builtins
470 from future_builtins import hex, oct
472 - Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
473 exponents for exponents with absolute value < 100. Follows C99
474 standard. This is a change on Windows, which would use 3 digits.
475 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
476 so that any alterations it does to the resulting string will be
477 available in stringlib/formatter.h (for float.__format__).
479 - Implemented PEP 3101, Advanced String Formatting. This adds a new
480 builtin format(); a format() method for str and unicode; a
481 __format__() method to object, str, unicode, int, long, float, and
482 datetime; the class string.Formatter; and the C API
485 - Fixed several potential crashes, all caused by specially crafted __del__
486 methods exploiting objects in temporarily inconsistent state.
488 - Issue #2115: Important speedup in setting __slot__ attributes. Also
489 prevent a possible crash: an Abstract Base Class would try to access a slot
490 on a registered virtual subclass.
492 - Fixed repr() and str() of complex numbers with infinity or nan as real or
495 - Clear all free lists during a gc.collect() of the highest generation in order
496 to allow pymalloc to free more arenas. Python may give back memory to the
499 - Issue #2045: Fix an infinite recursion triggered when printing a subclass of
500 collections.defaultdict, if its default_factory is set to a bound method.
502 - Fixed a minor memory leak in dictobject.c. The content of the free
503 list was not freed on interpreter shutdown.
505 - Limit free list of method and builtin function objects to 256 entries
508 - Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
509 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
510 to compact the internal free lists of pre-allocted ints and floats.
512 - Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
513 Python expected the return type int but the fork familie returns pi_t.
515 - Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
516 in the same code unit.
518 - Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
519 the collections.Sequence API.
521 - Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak
524 - Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear the
525 internal lookup cache for ref leak tests.
527 - Patch #1473257: generator objects gain a gi_code attribute. This is the
528 same object as the func_code attribute of the function that produced the
531 - Issue #1920: "while 0" statements were completely removed by the compiler,
532 even in the presence of an "else" clause, which is supposed to be run when
533 the condition is false. Now the compiler correctly emits bytecode for the
536 - A few crashers fixed: weakref_in_del.py (issue #1377858);
537 loosing_dict_ref.py (issue #1303614, test67.py);
538 borrowed_ref_[34].py (not in tracker).
540 - Issue #1069410: The "can't load dll" message box on Windows is
541 suppressed while an extension is loaded by calling SetErrorMode in
542 dynload_win.c. The error is still reported properly.
544 - Bug #1915: Python compiles with --enable-unicode=no again. However
545 several extension methods and modules do not work without unicode
548 - Issue #1882: when compiling code from a string, encoding cookies in the
549 second line of code were not always recognized correctly.
551 - Issue #1679: "0x" was taken as a valid integer literal.
553 - Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
556 - sys.float_info / PyFloat_GetInfo: The floating point information
557 object was converted from a dict to a specialized structseq object.
559 - Patch #1816: Added sys.flags structseq. It exposes the status of most
560 command line arguments and PYTHON* environment variables.
562 - Objects/structseq.c: Implemented new structseq representation. The patch
563 makes structseqs (e.g. the return value of os.stat) more readable.
565 - Patch #1700288: added a type attribute cache that caches method accesses,
566 resulting in speedups in heavily object-oriented code.
568 - Bug #1776: __import__() no longer accepts filenames on any platform.
569 The first parameter to __import__() must be a valid module name.
571 - Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
573 - Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
574 and sys.dont_write_bytecode attribute. All these can be set to forbid Python
575 to attempt to write compiled bytecode files.
577 - Improve some exception messages when Windows fails to load an extension
578 module. Now we get for example '%1 is not a valid Win32 application' instead
581 - Bug #1481296: Fixed long(float('nan'))!=0L.
583 - Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x, y)
586 - Issue #1635: Platform independent creation and representation of NaN
587 and INF. float("nan"), float("inf") and float("-inf") now work on every
588 platform with IEEE 754 semantics.
590 - Compiler now generates simpler and faster code for dictionary literals.
591 The oparg for BUILD_MAP now indicates an estimated dictionary size.
592 There is a new opcode, STORE_MAP, for adding entries to the dictionary.
594 - Issue #1638: %zd configure test fails on Linux
596 - Issue #1620: New property decorator syntax was modifying the decorator
597 in place instead of creating a new decorator object.
599 - Issue #1538: Avoid copying string in split/rsplit if the split
602 - Issue #1553: An erroneous __length_hint__ can make list() raise a
605 - PEP 366: Allow explicit relative imports when executing modules
606 inside packages with the -m switch via a new module level
607 __package__ attribute.
609 - Issue #1402: Fix a crash on exit, when another thread is still running, and
610 if the deallocation of its frames somehow calls the PyGILState_Ensure() /
611 PyGILState_Release() functions.
613 - Expose the Py_Py3kWarningFlag as sys.py3kwarning.
615 - Issue #1445: Fix a SystemError when accessing the ``cell_contents``
616 attribute of an empty cell object.
618 - Issue #1460: The utf-7 incremental decoder did not accept truncated input.
619 It now correctly saves its state between chunks of data.
621 - Patch #1739468: Directories and zipfiles containing a __main__.py file can
622 now be directly executed by passing their name to the interpreter. The
623 directory/zipfile is automatically inserted as the first entry in sys.path.
625 - Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
626 generator expression when at the same time the executed code is closing a
629 - sets and frozensets now have an isdisjoint() method.
631 - optimize the performance of builtin.sum().
633 - Fix warnings found by the new version of the Coverity checker.
635 - The enumerate() builtin function is no longer bounded to sequences smaller
636 than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
637 shifts from ints to longs.
639 - Issue #1686386: Tuple's tp_repr did not take into account the possibility of
640 having a self-referential tuple, which is possible from C code. Nor did
641 object's tp_str consider that a type's tp_str could do something that could
642 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
643 respectively, fixed the issues.
645 - Issue #1164: It was possible to trigger deadlock when using the 'print'
646 statement to write to a file since the GIL was not released as needed. Now
647 PyObject_Print() does the right thing along with various tp_print
648 implementations of the built-in types and those in the collections module.
650 - Issue #1147: Exceptions were directly allowing string exceptions in their
651 throw() method even though string exceptions no longer allowed.
653 - Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
654 list by using the recursion counter.
656 - Issue #1202533: Fix infinite recursion calls triggered by calls to
657 PyObject_Call() never calling back out to Python code to trigger recursion
658 depth updates/checks. Required the creation of a static RuntimeError
659 instance in case normalizing an exception put the recursion check value past
660 its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
662 - Patch #1031213: Decode source line in SyntaxErrors back to its original source
665 - Patch #1673759: add a missing overflow check when formatting floats
668 - Prevent expandtabs() on string and unicode objects from causing a segfault
669 when a large width is passed on 32-bit platforms.
671 - Bug #1733488: Fix compilation of bufferobject.c on AIX.
673 - Bug #1722485: remove docstrings again when running with -OO.
675 - Add new attribute names for function objects. All the func_* become
676 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
678 - Add -3 option to the interpreter to warn about features that are
679 deprecated and will be changed/removed in Python 3.0.
681 - Patch #1686487: you can now pass any mapping after '**' in function
684 - except clauses may now be spelled either "except E, target:" or
685 "except E as target:". This is to provide forwards compatibility with
688 - Deprecate BaseException.message as per PEP 352.
690 - Bug #1303614: don't expose object's __dict__ when the dict is
691 inherited from a builtin base.
693 - When __slots__ are set to a unicode string, make it work the same as
694 setting a plain string, ie don't expand to single letter identifiers.
696 - Request #1191699: Slices can now be pickled.
698 - Request #1193128: str.translate() now allows a None argument for
699 translations that only remove characters without re-mapping the
700 remaining characters.
702 - Patch #1682205: a TypeError while unpacking an iterable is no longer
703 masked by a generic one with the message "unpack non-sequence".
705 - Remove unused file Python/fmod.c.
707 - Bug #1683368: The object.__init__() and object.__new__() methods are
708 now stricter in rejecting excess arguments. The only time when
709 either allows excess arguments is when it is not overridden and the
710 other one is. For backwards compatibility, when both are
711 overridden, it is a deprecation warning (for now; maybe a Py3k
712 warning later). Also, type.__init__() insists on the same signature
713 as supported by type.__new__().
715 - Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
716 to complex using its __complex__() method before falling back to the
717 __float__() method. Therefore, the functions in the cmath module now
718 can operate on objects that define a __complex__() method.
720 - Patch #1623563: allow __class__ assignment for classes with __slots__.
721 The old and the new class are still required to have the same slot names.
723 - Patch #1642547: Fix an error/crash when encountering syntax errors in
724 complex if statements.
726 - Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
727 is called with an object that is faking its type.
729 - Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
732 - Patch #1444529: the builtin compile() now accepts keyword arguments.
734 - Bug #1678647: write a newline after printing an exception in any
735 case, even when converting the value to a string failed.
737 - The dir() function has been extended to call the __dir__() method on
738 its argument, if it exists. If not, it will work like before. This allows
739 customizing the output of dir() in the presence of a __getattr__().
741 - Patch #922167: Python no longer segfaults when faced with infinitely
742 self-recursive reload() calls (as reported by bug #742342).
744 - Patch #1675981: remove unreachable code from ``type.__new__()`` method.
746 - Patch #1491866: change the complex() constructor to allow parthensized
747 forms. This means complex(repr(x)) now works instead of raising a
750 - Patch #703779: unset __file__ in __main__ after running a file. This
751 makes the filenames the warning module prints much more sensible when
752 a PYTHONSTARTUP file is used.
754 - Variant of patch #697613: don't exit the interpreter on a SystemExit
755 exception if the -i command line option or PYTHONINSPECT environment
756 variable is given, but break into the interactive interpreter just like
757 on other exceptions or normal program exit.
759 - Patch #1638879: don't accept strings with embedded NUL bytes in long().
761 - Bug #1674503: close the file opened by execfile() in an error condition.
763 - Patch #1674228: when assigning a slice (old-style), check for the
764 sq_ass_slice instead of the sq_slice slot.
766 - When printing an unraisable error, don't print exceptions. before the name.
767 This duplicates the behavior whening normally printing exceptions.
769 - Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
771 - PEP 352: Raising a string exception now triggers a TypeError. Attempting to
772 catch a string exception raises DeprecationWarning.
774 - Bug #1377858: Fix the segfaulting of the interpreter when an object created
775 a weakref on itself during a __del__ call for new-style classes (classic
776 classes still have the bug).
778 - Bug #1579370: Make PyTraceBack_Here use the current thread, not the
779 frame's thread state.
781 - patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
783 - Prevent seg fault on shutdown which could occur if an object
786 - Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
787 to avoid relying on atexit.
789 - Bug #1590891: random.randrange don't return correct value for big number
791 - Patch #1586791: Better exception messages for some operations on strings,
794 - Bug #1067760: Deprecate passing floats to file.seek.
796 - Bug #1591996: Correctly forward exception in instance_contains().
798 - Bug #1588287: fix invalid assertion for `1,2` in debug builds.
800 - Bug #1576657: when setting a KeyError for a tuple key, make sure that
801 the tuple isn't used as the "exception arguments tuple".
803 - Bug #1565514, SystemError not raised on too many nested blocks.
805 - Bug #1576174: WindowsError now displays the windows error code
806 again, no longer the posix error code.
808 - Patch #1549049: Support long values in structmember, issue warnings
809 if the assigned value for structmember fields gets truncated.
811 - Update the peephole optimizer to remove more dead code (jumps after returns)
812 and inline unconditional jumps to returns.
814 - Bug #1545497: when given an explicit base, int() did ignore NULs
815 embedded in the string to convert.
817 - Bug #1569998: break inside a try statement (outside a loop) is now
818 recognized and rejected.
820 - list.pop(x) accepts any object x following the __index__ protocol.
822 - A number of places, including integer negation and absolute value,
823 were fixed to not rely on undefined behaviour of the C compiler
826 - Bug #1566800: make sure that EnvironmentError can be called with any
827 number of arguments, as was the case in Python 2.4.
829 - Patch #1567691: super() and new.instancemethod() now don't accept
830 keyword arguments any more (previously they accepted them, but didn't
833 - Fix a bug in the parser's future statement handling that led to "with"
834 not being recognized as a keyword after, e.g., this statement:
835 from __future__ import division, with_statement
837 - Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).
839 - Fix %zd string formatting on Mac OS X so it prints negative numbers.
841 - Allow exception instances to be directly sliced again.
843 - Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
844 allows calling unicode() on exceptions classes directly to succeed.
846 - Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
847 Also make sure that every exception class has __module__ set to
850 - Bug #1550983: emit better error messages for erroneous relative
851 imports (if not in package and if beyond toplevel package).
853 - Overflow checking code in integer division ran afoul of new gcc
854 optimizations. Changed to be more standard-conforming.
856 - Patch #1542451: disallow continue anywhere under a finally.
858 - Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
860 - The return tuple from str.rpartition(sep) is (tail, sep, head) where
861 head is the original string if sep was not found.
863 - Bug #1520864: unpacking singleton tuples in list comprehensions and
864 generator expressions (x for x, in ... ) works again. Fixing this problem
865 required changing the .pyc magic number. This means that .pyc files
866 generated before 2.5c2 will be regenerated.
868 - ``with`` and ``as`` are now keywords.
870 - Bug #1664966: Fix crash in exec if Unicode filename can't be decoded.
872 - Issue #1537: Changed GeneratorExit's base class from Exception to
875 - Fix Issue #1703448: A joined thread could show up in the
876 threading.enumerate() list after the join() for a brief period until
883 - #2274 Add heapq.heappushpop().
885 - Add inspect.isabstract(object) to fix bug #2223

889 - Add a timing parameter when using trace.Trace to print out timestamps.
891 - #1627: httplib now ignores negative Content-Length headers.
893 - #900744: If an invalid chunked-encoding header is sent by a server,
894 httplib will now raise IncompleteRead and close the connection instead
895 of raising ValueError.
897 - #1492: The content type of BaseHTTPServer error messages can now be
900 - Issue 1781: ConfigParser now does not let you add the "default" section
903 - Removed uses of dict.has_key() from distutils, and uses of
904 callable() from copy_reg.py, so the interpreter now starts up
905 without warnings when '-3' is given. More work like this needs to
906 be done in the rest of the stdlib.
908 - Issue #1916. Added isgenerator() and isgeneratorfunction() to inspect.py.
910 - #1224: Fixed bad url parsing when path begins with double slash.
912 - ctypes instances that are not or do not contain pointers can now be
915 - Patch #1966: Break infinite loop in httplib when the servers
916 implements the chunked encoding incorrectly.
918 - Rename rational.py to fractions.py and the rational.Rational class
919 to fractions.Fraction, to avoid the name clash with the abstract
920 base class numbers.Rational. See discussion in issue #1682.
922 - The pickletools module now provides an optimize() function
923 that eliminates unused PUT opcodes from a pickle string.
925 - #2021: Allow tempfile.NamedTemporaryFile and SpooledTemporaryFile
926 to be used in with statements by correctly supporting the context
929 - #1979: Add rich comparisons to Decimal, and make Decimal comparisons
930 involving a NaN follow the IEEE 754 standard.
932 - #2004: tarfile.py: Use mode 0700 for temporary directories and default
933 permissions for missing directories.
935 - #175006: The debugger used to skip the condition of a "while" statement
936 after the first iteration. Now it correctly steps on the expression, and
937 breakpoints on the "while" statement are honored on each loop.
939 - #1765140: add an optional delay argument to FileHandler and its
940 subclasses. Defaults to false (existing behaviour), but if true,
941 defers opening the file until the first call to emit().
943 - The pprint module now supports sets and frozensets.
945 - #1221598: add optional callbacks to ftplib.FTP's storbinary() and
946 storlines() methods. (Contributed by Phil Schwartz)

976 - #856047: respect the ``no_proxy`` environment variable when using the
977 ``http_proxy`` etc. environment variables in urllib.
979 - #1178141: add a getcode() method to the addinfourls that urllib.open()

1006 - Patch #1048820: Add insert-mode editing to curses.textpad.Textbox
1007 (patch by Stefan Wehr). Also, fix an off-by-one bug in
1010 - Issue #1831: ctypes now raises a TypeError if conflicting positional
1011 and named arguments are passed to a Structure or Union initializer.
1012 When too many positional arguments are passed, also a TypeError is
1013 raised instead of a ValueError.
1015 - Convert the internal ctypes array type cache to a WeakValueDict so
1016 that array types do not live longer than needed.
1018 - Issue #1786: pdb should use its own stdin/stdout around an exec call
1019 and when creating a recursive instance.
1021 - Issue #1698398 Zipfile.printdir() crashed because the format string
1022 expected a tuple type of length six instead of time.struct_time object.

1029 that returned a tuple now return a named tuple.
1031 - Doctest now returns results as a named tuple for readability:
1032 (0, 7) --> TestResults(failed=0, attempted=7)
1034 - Issue #846388. re.match is interruptible now, which is particularly
1035 good for long regular expression matches.
1037 - pyexpat, patch #1137: allow setting buffer_size attribute
1038 on Parser objects to set the character data buffer size.
1040 - Issue #1757: The hash of a Decimal instance is no longer affected by
1041 the current context.

1070 - Issue #1642: Fix segfault in ctypes when trying to delete attributes.
1072 - Issue #1727780: Support loading pickles of random.Random objects created
1073 on 32-bit systems on 64-bit systems, and vice versa. As a consequence
1074 of the change, Random pickles created by Python 2.6 cannot be loaded
1077 - Issue #1455: The distutils package now supports VS 2005 and VS 2008 for
1078 both the msvccompiler and cygwincompiler.

1084 internal floating point type to the sys module.
1086 - Issue 1429818: patch for trace and doctest modules so they play nicely
1089 - doctest made a bad assumption that a package's __loader__.get_data()
1090 method used universal newlines.
1092 - Issue #1705170: contextlib.contextmanager was still swallowing
1093 StopIteration in some cases. This should no longer happen.
1095 - Issue #1292: On alpha, arm, ppc, and s390 linux systems the
1096 --with-system-ffi configure option defaults to "yes".
1098 - IN module for FreeBSD 8 is added and preexisting FreeBSD 6 and 7

1108 --disable-toolbox-glue.
1110 - collections.deque() now supports a "maxlen" argument.
1112 - itertools.count() is no longer bounded to LONG_MAX. Formerly, it raised
1113 an OverflowError. Now, automatically shifts from ints to longs.
1115 - Added itertools.product() which forms the Cartesian product of
1116 the input iterables.
1118 - Added itertools.combinations() and itertools.permutations().
1120 - Patch #1541463: optimize performance of cgi.FieldStorage operations.
1122 - Decimal is fully updated to the latest Decimal Specification (v1.66).
1124 - Bug #1153: repr.repr() now doesn't require set and dictionary items

1163 sideeffect the representation of these instances has changed.
1165 - tarfile.py: Added "exclude" keyword argument to TarFile.add().
1167 - Bug #1734723: Fix repr.Repr() so it doesn't ignore the maxtuple attribute.

1170 that it actually works with HTTP, HTTPS, FTP and FTPS connections).
1172 - In ftplib, the FTP.ntransfercmd method, when in passive mode, now uses
1173 the socket.create_connection function, using the timeout specified at
1176 - Bug #1728403: Fix a bug that CJKCodecs StreamReader hangs when it
1177 reads a file that ends with incomplete sequence and sizehint argument
1178 for .read() is specified.
1180 - Bug #1730389: Change time.strptime() to use ``\s+`` instead of ``\s*`` when
1181 matching spaces in the specified format argument.
1183 - SF 1668596/1720897: distutils now copies data files

1186 - sha now raises a DeprecationWarning upon import.
1188 - md5 now raises a DeprecationWarning upon import.
1190 - Issue1385: The hmac module now computes the correct hmac when using hashes
1191 with a block size other than 64 bytes (such as sha384 and sha512).
1193 - mimify now raises a DeprecationWarning upon import.
1195 - MimeWriter now raises a DeprecationWarning upon import.
1197 - tarfile.py: Improved unicode support. Unicode input names are now
1198 officially supported. Added "errors" argument to the TarFile class.
1200 - urllib.ftpwrapper class now accepts an optional timeout.
1202 - shlex.split() now has an optional "posix" parameter.
1204 - The posixfile module now raises a DeprecationWarning.
1206 - Remove the gopherlib module. This also leads to the removal of gopher
1207 support in urllib/urllib2.

1210 lack of an infinite recursion check.
1212 - Removed plat-freebsd2 and plat-freebsd3 directories (and IN.py in

1216 the traceback inadvertently or maliciously closing the comment and
1217 injecting HTML into the error page.
1219 - The popen2 module and os.popen* are deprecated. Use the subprocess module.
1221 - Added an optional credentials argument to SMTPHandler, for use with SMTP
1222 servers which require authentication.
1224 - Patch #1695948: Added optional timeout parameter to SocketHandler.
1226 - Bug #1652788: Minor fix for currentframe.
1228 - Patch #1598415: Added WatchedFileHandler to better support external
1229 log file rotation using e.g. newsyslog or logrotate. This handler is
1230 only useful in Unix/Linux environments.
1232 - Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
1233 (as opposed to the command line) will now write file names ending in
1236 - As specified in RFC 2616, an HTTP response like 2xx indicates that
1237 the client's request was successfully received, understood, and accepted.
1238 Now in these cases no error is raised in urllib (issue #1177) and urllib2.

1241 properly recreated when the locale is changed.
1243 - Patch #1685563: remove (don't add) duplicate paths in distutils.MSVCCompiler.
1245 - Added a timeout parameter to the constructor of other protocols
1246 (telnetlib, ftplib, smtplib and poplib). This is second part of the
1247 work started with create_connection() and timeout in httplib, and
1248 closes patch #723312.
1250 - Patch #1676823: Added create_connection() to socket.py, which may be
1251 called with a timeout, and use it from httplib (whose HTTPConnection

1363 - unittest now verifies more of its assumptions. In particular, TestCase
1364 and TestSuite subclasses (not instances) are no longer accepted in
1365 TestSuite.addTest(). This should cause no incompatibility since it

1460 encoding (which can be None) in an attribute called "encoding".
1462 - Bug #411881: logging.handlers: bare except clause removed from
1463 SMTPHandler.emit. Now, only ImportError is trapped.

1570 ctypes isn't considered as requiring executable stacks.
1572 - ctypes callback functions only support 'fundamental' data types as
1573 result type. Raise an error when something else is used. This is a
1574 partial fix for Bug #1574584.
1576 - Fix turtle so that time.sleep is imported for the entire library. Allows
1577 the demo2 function to be executed on its own instead of only when the

1637 attributes are now stored directly as Py_ssize_t members).
1639 - Issue829951: In the smtplib module, SMTP.starttls() now complies with
1640 RFC 3207 and forgets any knowledge obtained from the server not obtained
1641 from the TLS negotiation itself. Patch contributed by Bill Fenner.
1643 - Issue1339: The smtplib.SMTP class has been refactored a bit such
1644 that the SMTP.starttls() caller no longer needs to call ehlo()
1645 beforehand. SMTP.starttls() now raises an exception of the server

1711 line with that for list.__init__().
1713 - Added wide char functions to msvcrt module: getwch, getwche, putwch and
1714 ungetwch. The functions accept or return unicode.

1738 time so that opening a database previously created with the DB_DUP or
1739 DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
1740 Specifically: dictionary assignment to a DB object will replace all
1741 values for a given key when the database allows duplicate values.
1742 DB users should use DB.put(k, v) when they want to store duplicates; not

1747 - Bug #1686475: Support stat'ing open files on Windows again.
1749 - Patch #1185447: binascii.b2a_qp() now correctly quotes binary characters
1750 with ASCII value less than 32. Also, it correctly quotes dots only if

1831 - Bug #1552726: in readline.c, avoid repeatedly polling in interactive
1832 mode by only placing a timeout on the select() if an input hook has
1833 been defined. This prevents an interactive Python from waking up 10
1834 times per second. Patch by Richard Boulton.

1861 - Refactor test_logging to use unittest.
1863 - Refactor test_profile and test_cprofile to use the same code to profile.
1865 - Make test_runpy reentrant by fixing _check_module to clear out any module
1866 being tested. Was causing an error by __import__ doing a reload on the
1867 second run and thus suppressing bytecode recreation.
1869 - Capture socket connection resets and timeouts in test_socket_ssl and
1870 test_urllib2net and raise test.test_support.ResourceDenied.

2058 - Makefile.pre.in(buildbottest): Run an optional script pybuildbot.identify
2059 to include some information about the build environment.
2065 - Unified naming convention for free lists and their limits. All free lists
2066 in Object/ are named ``free_list``, the counter ``numfree`` and the upper
2067 limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
2069 - ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
2070 ``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
2071 it does not steal a reference to the added item.
2073 - Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
2075 - Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
2076 _FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t

2082 ``PyFloat_GetInfo()`` to the float API.
2084 - Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
2085 format code incorrectly truncated the length to an int, even when
2086 PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
2087 results with huge strings.
2089 - Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
2092 - PEP 3123: Provide forward compatibility with Python 3.0, while keeping
2093 backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
2094 PyVarObject_HEAD_INIT.
2096 - Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
2098 - Patch #1733960: Allow T_LONGLONG to accept ints.
2100 - T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
2102 - Added a new API function ``PyImport_ImportModuleNoBlock``.
2104 - Bug #1637022: Prefix AST symbols with _Py_.
2106 - Fix some leftovers from the conversion from int to Py_ssize_t
2107 (relevant to strings and sequences of more than 2**31 items).

2110 outside of pystate.c and should not be necessary.
2112 - ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
2113 imports. In earlier versions they might have used relative imports under
2116 - Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
2117 and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
2119 - Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
2120 so it can be used as an expression.
2126 - Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
2127 Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to
2128 Win2k for x86/32bit builds and WinXP for AMD64 builds.
2130 - Conditionalize definition of _CRT_SECURE_NO_DEPRECATE
2131 and _CRT_NONSTDC_NO_DEPRECATE.
2133 - Bug #1216: Restore support for Visual Studio 2002.
2139 - cfmfile now raises a DeprecationWarning.
2141 - buildtools now raises a DeprecationWarning.
2143 - Removed the macfs module. It had been deprecated since Python 2.5. This
2144 lead to the deprecation of macostools.touched() as it relied solely on macfs
2145 and was a no-op under OS X.
