631
632- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
633 and later systems as is currently done for Python 3.x installers.
634 For 2.7.7 only, we will provide three installers:
635 the legacy deprecated 10.3+ 32-bit-only format;
636 the newer 10.5+ 32-bit-only format;
637 and the unchanged 10.6+ 64-/32-bit format.
638 Although binary installers will no longer be available from
639 python.org as of 2.7.8, it will still be possible to build from
640 source on 10.3.9 and 10.4 systems if necessary.
641 See Mac/BuildScript/README.txt for more information.

2019 In particular, fix extension module build failures when trying to use
2020 32-bit-only installer Pythons on systems with Xcode 4 (currently
2021 OS X 10.8, 10.7, and optionally 10.6).
2022 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2023 * Since Xcode 4 removes ppc support, extension module builds now
2024 check for ppc compiler support and by default remove ppc and
2025 ppc64 archs when they are not available.
2026 * Extension module builds now revert to using system installed
2027 headers and libs (/usr and /System/Library) if the SDK used
2028 to build the interpreter is not installed or has moved.
2029 * Try to avoid building extension modules with deprecated
2030 and problematic Apple llvm-gcc compiler. If original compiler

Mark Dickinsondbbed042011-09-19 16:38:08 +01002382- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2383 int.__pow__. These overflow checks were causing int.__pow__ to produce
2384 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002385 compiler optimizing the check away. Also fix similar overflow checks
2386 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2387 bugs caused test failures with recent versions of Clang.

2400 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +01002455- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002456 has left two versions of customize_compiler, the original in
2457 distutils.sysconfig and another copy in distutils.ccompiler, with some

2460 is the case in 3.x.
2461
Ned Deily0d0ea482012-02-10 12:59:06 +01002462- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2463 Distutils-based packages with C extension modules may fail because
2464 Apple has removed gcc-4.2, the version used to build python.org
2465 64-bit/32-bit Pythons. If the user does not explicitly override
2466 the default C compiler by setting the CC environment variable,
2467 Distutils will now attempt to compile extension modules with clang
2468 if gcc-4.2 is required but not found. Also as a convenience, if
2469 the user does explicitly set CC, substitute its value as the default
2470 compiler in the Distutils LDSHARED configuration variable for OS X.
2471 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2472 SDK, neither of which are available in Xcode 4. This change does not
2473 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002723- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2724 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2725 interpreter process. This could cause failures in non-Distutils subprocesses
2726 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002727 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002728 deployment target only in the environment of each build subprocess. It is
2729 still possible to globally override the default by setting
2730 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2731 greater or equal to the default value, the value with which the interpreter
2732 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002760- sys.setcheckinterval() now updates the current ticker count as well as
2761 updating the check interval, so if the user decreases the check interval,
2762 the ticker doesn't have to wind down to zero from the old starting point
2763 before the new interval takes effect. And if the user increases the
2764 interval, it makes sure the new limit takes effect right away rather have an
2765 early task switch before recognizing the new interval.

3746 This prevents user-created self-referencing ordered dictionaries from
3747 becoming permanently uncollectable GC garbage. The downside is that
3748 removing __del__ means that the internal doubly-linked list has to wait for
3749 GC collection rather than freeing memory immediately when the refcnt drops

4207
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004208- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4209 start byte and the continuation byte(s) are now considered invalid, instead
4210 of the number of bytes specified by the start byte.
4211 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4212 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4213 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4214 Previous versions returned a single u'\ufffd'.

4220 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004222- Issue #8748: Fix two issues with comparisons between complex and integer
4223 objects. (1) The comparison could incorrectly return True in some cases
4224 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4225 (2) The comparison raised an OverflowError for large integers, leading
4226 to unpredictable exceptions when combining integers and complex objects
4227 in sets or dicts.
4228
Mark Dickinson81336372010-05-30 12:12:25 +00004229- Issue #5211: Implicit coercion for the complex type is now completely
4230 removed. (Coercion for arithmetic operations was already removed in 2.7

Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004233- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00004366- Issue #1533: Fix inconsistency in range function argument processing: any
4367 non-float non-integer argument is now converted to an integer (if possible)
4368 using its __int__ method. Previously, only small arguments were treated this
4369 way; larger arguments (those whose __int__ was outside the range of a C long)
4370 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004378 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00004379 benefit compared to the dynamic memory allocation fallback. Patch by
4380 Charles-François Natali.

4405 messages when accessing undefined class attributes because of the cheap
4406 inheritance with the underlying socket object. The cheap inheritance has been
4407 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00004408

Georg Brandlfee0f442010-05-22 21:26:21 +00004420- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4421 operation raises multiple signals and more than one of those signals is
4422 trapped, the specification determines the order in which the signals should be
4423 handled. In many cases this order wasn't being followed, leading to the wrong
4424 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00004425

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004590
4591Core and Builtins
4592-----------------
4593
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004594- Issue #7301: Add environment variable $PYTHONWARNINGS.
4595
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004596- Issue #8329: Don't return the same lists from select.select when no fds are
4597 changed.
4598
Georg Brandlfee0f442010-05-22 21:26:21 +00004599- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004600 on 64-bit machines. The shift count for either left or right shift is
4601 permitted to be up to sys.maxsize.
4602
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004603- Ensure that tokenization of identifiers is not affected by locale.
4604
Georg Brandlfee0f442010-05-22 21:26:21 +00004605- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004606
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004607- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4608
Georg Brandlfee0f442010-05-22 21:26:21 +00004609- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4610 with a non-empty format string. This is an effort to future-proof user
4611 code. If a derived class does not currently implement __format__ but later
4612 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004613 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004614 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004615
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004616- Issue #8268: Old-style classes (not just instances) now support weak
4617 references.
4618
Georg Brandlfee0f442010-05-22 21:26:21 +00004619- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4620 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004621
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004622- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00004623
Benjamin Peterson96545892010-03-21 20:21:00 +00004624- Issue #6474: Make error message from passing an inadequate number of keyword
4625 arguments to a function correct.
4626
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004627- Issue #8164: Don't allow lambda functions to have a docstring.
4628
Victor Stinner66644262010-03-10 22:30:19 +00004629- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004630 (SIGINT). If an error occurs while importing the site module, the error is
4631 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004632 module.
4633
Collin Winter001a3952010-03-18 21:54:01 +00004634- Code objects now support weak references.
4635
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004636Library
4637-------
4638
R. David Murray661303f2010-04-13 20:57:40 +00004639- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4640
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004641- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004642 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4643 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004644
Benjamin Peterson76a23c12010-04-04 23:23:22 +00004645- Issue #8310: Allow dis to examine new style classes.
4646
Georg Brandlfee0f442010-05-22 21:26:21 +00004647- Issue #8257: The Decimal construct now accepts a float instance directly,
4648 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004649
4650 >>> Decimal(1.1)
4651 Decimal('1.100000000000000088817841970012523233890533447265625')
4652
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004653- collections.Counter() now supports a subtract() method.
4654
Georg Brandlfee0f442010-05-22 21:26:21 +00004655- The functools module now has a total_ordering() class decorator to simplify
4656 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004657
Georg Brandlfee0f442010-05-22 21:26:21 +00004658- The functools module also adds cmp_to_key() as a tool to transition old-style
4659 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004660
Georg Brandlfee0f442010-05-22 21:26:21 +00004661- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4662 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004663
Georg Brandlfee0f442010-05-22 21:26:21 +00004664- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4665 InvalidOperation instead of returning False. (Comparisons involving a quiet
4666 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4667 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004668
Georg Brandlfee0f442010-05-22 21:26:21 +00004669- Issue #2531: Comparison operations between floats and Decimal instances now
4670 return a result based on the numeric values of the operands; previously they
4671 returned an arbitrary result based on the relative ordering of id(float) and
4672 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004673
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004674- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004675 argument `-` which tells it to read files to compile from stdin. Each line is
4676 read on demand and the named file is compiled immediately. (Original patch by
4677 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004678
Georg Brandlfee0f442010-05-22 21:26:21 +00004679- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4680 function like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +00004681
Florent Xicluna58b65662010-03-30 16:29:03 +00004682- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4683 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004684 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004685
Georg Brandlfee0f442010-05-22 21:26:21 +00004686- Comparisons using one of <, <=, >, >= between a complex instance and a
4687 Fractions instance now raise TypeError instead of returning True/False. This
4688 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4689 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004690
Michael Foorde6410c52010-03-29 20:04:23 +00004691- Addition of ``WeakSet`` to the ``weakref`` module.

4699
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004700- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004701 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4702 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004703
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004704- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4705 deprecated.
4706
Georg Brandlfee0f442010-05-22 21:26:21 +00004707- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4708 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004709

4714 existing at the same time, causing a Unicode error when configuration code
4715 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004716
Georg Brandlfee0f442010-05-22 21:26:21 +00004717- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4718 when logging occurs.

Antoine Pitroueee91cd2010-03-26 19:27:16 +00004720- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4721 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4722 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00004723
Florent Xiclunacf82fa62010-03-21 12:27:20 +00004724- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004744- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004745 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4746 log file to compute the next rollover time. If the log file does not exist,
4747 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004748

Georg Brandlba83f822010-03-14 09:50:54 +00004757- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4758 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4759 This is a behavior change, so email's minor version number is now bumped, to
4760 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004788- Issue #8300: When passing a non-integer argument to struct.pack with any
4789 integer format code, struct.pack first attempts to convert the non-integer
4790 using its __index__ method. If that method is non-existent or raises
4791 TypeError it goes on to try the __int__ method, as described below.
4792
Georg Brandlba83f822010-03-14 09:50:54 +00004793- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4794 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4795 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004796 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4797 inconsistent: __int__ was used for some integer codes but not for others, and
4798 the set of integer codes for which it was used differed between native packing
4799 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005051- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5052 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5053 returning NULL. The macro now returns a statically allocated empty string
5054 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00005063 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
5064 strings,
5065 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5066 numeric strings corresponding to subnormal values,
5067 (3) a memory leak for some values large enough to cause overflow, and
5068 (4) a number of flaws that could lead to incorrectly rounded results.

5203Core and Builtins
5204-----------------
5205
Georg Brandlba83f822010-03-14 09:50:54 +00005206- The ``__complex__()`` method is now looked up on the class of instances to
5207 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005209- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5210 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5211
Mark Dickinson1b34d252010-01-01 17:27:30 +00005212- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005213 DeprecationWarning when passed a float argument where an integer was expected.
5214 These functions and methods now raise TypeError instead. The majority of the
5215 effects of this change are in the extension modules, but some core functions
5216 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5217 and many unicode/str methods.

5228 used to drop the time part of the result.
5229
Georg Brandlba83f822010-03-14 09:50:54 +00005230- Issue #1811: Improve accuracy and cross-platform consistency for true division
5231 of integers: the result of a/b is now correctly rounded for ints a and b (at
5232 least on IEEE 754 platforms), and in particular does not depend on the
5233 internal representation of a long.

5241
Georg Brandlba83f822010-03-14 09:50:54 +00005242 These executables now work properly with the arch(1) command: ``arch -ppc
5243 python`` will start a universal binary version of python in PPC mode (unlike

5383 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005384

5386 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00005399- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5400 decimal string that's guaranteed to round back to x under correct rounding
5401 (with round-half-to-even rounding mode). Previously it gave a string based on
5402 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5403 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5404 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005405
Georg Brandlba83f822010-03-14 09:50:54 +00005406- Issue #7117: On almost all platforms: float-to-string and string-to-float
5407 conversions within Python are now correctly rounded. Places these conversions
5408 occur include: str for floats and complex numbers; the float and complex
5409 constructors; old-style and new-style numeric formatting; serialization and
5410 deserialization of floats and complex numbers using marshal, pickle and json;
5411 parsing of float and imaginary literals in Python code; Decimal-to-float
5412 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005413
Georg Brandlba83f822010-03-14 09:50:54 +00005414 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5415 providing correctly-rounded strtod and dtoa C functions. This code is
5416 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5417 the C compiler. There may be a small number of platforms on which correct
5418 operation of this code cannot be guaranteed, so the code is not used: notably,
5419 this applies to platforms where the C double format is not IEEE 754 binary64,
5420 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5421 and Python's configure script is unable to determine how to change the FPU
5422 precision. On these platforms conversions use the platform strtod and dtoa,
5423 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005425- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5426 uses the correctly-rounded string <-> float conversions described above (when
5427 available), and so produces correctly rounded results that will display nicely
5428 under the float repr. There are two related small changes: (1) round now
5429 accepts any class with an ``__index__()`` method for its second argument (but
5430 no longer accepts floats for the second argument), and (2) an excessively
5431 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5432 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005574
Georg Brandlba83f822010-03-14 09:50:54 +00005575 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5576 (2) parsing of strings representing infinities and nans was locale aware; and
5577 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005579- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5580 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5581 but with at least one decimal point and with a default precision
5582 of 12. Previously, the behavior the same but with a default precision of 6.
5583 This more closely matches ``str()``, and reduces surprises when adding
5584 alignment flags to the empty presentation type. This also affects the new
5585 complex.__format__ in the same way.
5586
5587- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5659 internal representation of integers, for performance reasons. Base 2**30 is
5660 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00005763- Issue #4597: Fixed exception handling when the __exit__ function of a context
5764 manager returns a value that cannot be converted to a bool.

Georg Brandlba83f822010-03-14 09:50:54 +00005768- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5769 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5770 instances. On a typical machine this saves 3 bytes of memory (on average) per
5771 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005773- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5774 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5775 instead of throwing a MemoryError.
5776
Georg Brandlba83f822010-03-14 09:50:54 +00005777- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5778 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005779
Benjamin Petersonc078f922008-11-21 22:27:24 +00005780- Issue #4367: Python would segfault during compiling when the unicodedata
5781 module couldn't be imported and \N escapes were present.
5782
Georg Brandlba83f822010-03-14 09:50:54 +00005783- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5784 file objects with closefd=False. The file descriptor is still kept open but
5785 the file object behaves like a closed file. The ``FileIO`` object also got a
5786 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005787
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005788- Issue #4348: Some bytearray methods returned that didn't cause any change to
5789 the bytearray, returned the same bytearray instead of a copy.
5790
Georg Brandlba83f822010-03-14 09:50:54 +00005791- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

5794
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005795- Issue #4048: The parser module now correctly validates relative imports.
5796
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005797- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
5798 exec statement.
5799
Georg Brandlba83f822010-03-14 09:50:54 +00005800- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
5801 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00005802
Benjamin Petersonbdca9422008-10-26 20:21:13 +00005803- Issue #4209: Enabling unicode_literals and the print_function in the same
5804 __future__ import didn't work.
5805
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005806- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005807 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005808
Georg Brandlba83f822010-03-14 09:50:54 +00005809- On windows, ``os.chdir()`` given unicode was not working if
5810 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5811 this code path is really executed because I cannot move to such directory on
5812 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005813
Georg Brandlba83f822010-03-14 09:50:54 +00005814- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5815 element is temporarily replaced with an equivalent frozenset. But the
5816 eventual KeyError would always report the empty ``frozenset()`` as the missing
5817 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005818
Georg Brandlba83f822010-03-14 09:50:54 +00005819- Issue #4509: Various issues surrounding resize of bytearray objects to which
5820 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00005821
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00005822- Issue #4748: Lambda generators no longer return a value.

5825
Gregory P. Smithae91d092009-03-02 05:13:57 +00005826- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
5827
Georg Brandlba83f822010-03-14 09:50:54 +00005828- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
5829 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00005830
Matthias Klose91a3b9e2009-04-05 21:19:13 +00005831- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5832 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00005833
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005834- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5835 returned them on 64bit platforms.
5836
Walter Dörwalded960ac2009-05-03 22:36:33 +00005837- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5838 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5839 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5840 of using the replace error handler in PyUnicode_DecodeUTF8().
5841
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005842- Issue #3739: The unicode-internal encoder now reports the number of characters
5843 consumed like any other encoder (instead of the number of bytes).
5844
Georg Brandlba83f822010-03-14 09:50:54 +00005845- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5846 allocator will be automatically disabled when running under Valgrind. This
5847 gives improved memory leak detection when running under Valgrind, while taking
5848 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00005873- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
5874 ownership when the group is not forced, because the group may be different
5875 from the user's group and inherit from its container when the test is run.

5919 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00005920 __main__.py file. This allows applications that run other Python scripts to

Georg Brandlba83f822010-03-14 09:50:54 +00005923- Issue #7318: multiprocessing now uses a timeout when it fails to establish a

7018 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7019 neither __int__ nor __long__, TypeError used to be raised (with a

7217
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007218- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7219 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7220 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7221 ``printf`` function, whereas PyString_FromFormat has an independent
7222 implementation and uses "%zd" on all platforms for size_t values.
7223 This makes a difference on win64, where ``printf`` needs "%Id" to display
7224 64bit values.

7230 object; previously an int would be returned for small values. the __long__
7231 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007241 was correctly parsed but parsing of subsequent arguments failed.
7242
Vinay Sajip35e3b032008-09-01 14:33:59 +00007243- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007244 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7245 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7246 when given a tuple of classes as second argument, were looking up
7247 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7248 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00007395- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7396 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7397 extensions do not automatically benefit from the class attribute
7398 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7399 to their tp_flags field if they care. This is a backwards
7400 compatibility feature; in 3.0, all types will use the cache by
7401 default.
7402
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007403- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00007416- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7417 ValueError consistently across platforms.
7418
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007419- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7420 (64bit Unix, for example), unichr() would truncate its argument and return
7421 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00007423- Apply security patches from Apple.
7424
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007425- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7426 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7427
Antoine Pitrou92f82162008-07-25 22:22:08 +00007428- Issue #1819: function calls with several named parameters are now on
7429 average 35% faster (as measured by pybench).
7430
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007431- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7432 the python debugger steps into a class statement: the free variables (local
7433 variables defined in an outer scope) would be deleted from the outer scope.
7434
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007435- Issue #2620: Overflow checking when allocating or reallocating memory
7436 was not always being done properly in some python types and extension
7437 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7438 all been updated to perform better checks and places in the code that
7439 would previously leak memory on the error path when such an allocation
7440 failed have been fixed.

7446
Benjamin Petersone977ad42008-08-20 01:42:01 +00007447- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7448 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7449
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007450- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7451 version reported by these tools does not necessarily follow the python
7452 version numbering scheme, so the module is less strict when parsing it.
7453
Nick Coghlanf70385a2008-08-18 12:42:46 +00007454- Issue #2235: Added Py3k warnings for types which will become unhashable
7455 under the stricter __hash__ inheritance rules in 3.0. Several types
7456 which did not meet the rules for hash invariants and were already
7457 unhashable in 3.0 have now been explicitly flagged as unhashable in
7458 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7459 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7460
Brett Cannon88f801d2008-08-18 00:46:22 +00007461- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7462 imported into the module but exposed as part of the module's API.

Brett Cannonbf3157b2008-08-14 05:00:03 +00007492- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7493 since mimetools itself is deprecated. Because modules are cached, all
7494 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7495
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007496- Issue #3134: shutil referenced undefined WindowsError symbol.

7505 a MemoryError rather than silently stop the iteration.
7506
Guido van Rossum59ce9012008-08-09 14:55:34 +00007507- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7508 to _sre.compile() will now be rejected. This should not affect anybody
7509 since the re.compile() function never generates invalid re-bytecode.
7510
Skip Montanaroa032bf42008-08-08 22:52:51 +00007511- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7512 upon first access it can be automatically initialized from the csv file if
7513 it wasn't initialized during instantiation.
7514
Brett Cannon3aa2a492008-08-06 22:28:09 +00007515- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7516 the reload() built-in has been removed.
7517
Brett Cannon7e30b672008-08-04 21:52:25 +00007518- Changed code in the following modules/packages to remove warnings raised

7527 raised an AttributeError.
7528

Antoine Pitroude781a42008-08-09 12:43:23 +00007530 asking for a specific length. This problem only affected files opened
7531 using the new "io" module, not the built-in open() function.

7557 file name rather than a ZipInfo instance, so files are extracted with
7558 mode 0600 rather than 000 under Unix.
7559
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007560- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7561 argument in python 2.5, this broke code that subclassed Popen to include its
7562 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007572- Issue #2235: the C API function PyObject_HashNotImplemented and its
7573 interaction with the tp_hash slot (added in 2.6b2) are now documented
7574
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007575- Issue #643841: The language reference now provides more detailed
7576 coverage of the lookup process for special methods. The disclaimers
7577 regarding lack of coverage of new-style classes have also been
7578 removed, since the coverage is now fairly reasonable.

7582================================
7583
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007584*Release date: 17-Jul-2008*
7585
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007586Core and Builtins
7587-----------------
7588
Georg Brandl3e483f62008-07-16 22:57:41 +00007589- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7590 its methods now allow for items objects that can be converted to
7591 an integer using operator.index().
7592
Mark Dickinson64b7e502008-07-16 09:40:03 +00007593- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7594 produced a ValueError instead of giving the correct float.
7595
Eric Smitha5fa5a22008-07-16 00:11:49 +00007596- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7597 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7598
Mark Dickinson7103aa42008-07-15 19:08:33 +00007599- Issue #3008: the float type has a new instance method 'float.hex'
7600 and a new class method 'float.fromhex' to convert floating-point
7601 numbers to and from hexadecimal strings, respectively.
7602
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007603- Issue #2235: __hash__ is once again inherited by default. To allow
7604 collections.Hashable to remain meaningful in the presence of the
7605 default hash implementation (object.__hash__), it is now possible
7606 to explicit block inheritance of hash by setting __hash__=None at
7607 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7608 level.
7609
Nick Coghlanb028f502008-07-13 14:52:36 +00007610- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7611 the parent module cannot be found while performing an absolute import.
7612 This means that an incorrectly defined __package__ attribute will
7613 now only prevent relative imports in that module rather than causing
7614 all imports from that module to fail.
7615
Nick Coghlan14ff9942008-07-08 14:21:42 +00007616- Issue #2517: Allow unicode messages in Exceptions again by correctly
7617 bypassing the instance dictionary when looking up __unicode__ on
7618 new-style classes.
7619
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007620- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7621 set to a custom object whose write() method happens to install
7622 another file in sys.stdout.
7623
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007624- Issue #3088: Corrected a race condition in classes derived from
7625 threading.local: the first member set by a thread could be saved in
7626 another thread's dictionary.
7627
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007628- Issue #3004: Minor change to slice.indices(): the start and stop
7629 arguments are now treated identically, making the behaviour easier
7630 to describe and understand. For example, slice(None, -10,
7631 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7632 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7633 10, -1).
7634
Georg Brandl278fc502008-07-19 12:46:12 +00007635- Issue #3219: Calling a function with repeated keyword arguments,
7636 f(a=2, a=23), would not cause a syntax error. This was a regression
7637 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007638
Georg Brandl278fc502008-07-19 12:46:12 +00007639- Issue #2862: Make int and float freelist management consistent with
7640 other freelists. Changes their CompactFreeList apis into
7641 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007642

7644-------
7645
Thomas Heller57adf222008-08-14 19:10:48 +00007646- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7647 api functions without holding the GIL, which could lead to a fatal
7648 error when they failed.
7649
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007650- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7659 ForkingPickler.register() to resolve conflict with ctypes.
7660
Vinay Sajip51e65192008-07-18 09:01:10 +00007661- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00007663- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7664 a valid dlerror() message.
7665
Thomas Heller2bad6572008-07-15 17:19:50 +00007666- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7667 incomplete structure was created.
7668
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007669- Issue #3339: dummy_thread.acquire() should not return None.

7672
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007673- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007674
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007675- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7676 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007677 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007678 content-length. The problem had been corrected in the 2.4 branch, but never
7679 merged into trunk.
7680
Georg Brandle78fbcc2008-07-05 10:13:36 +00007681- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00007691- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007692 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007693
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007694- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00008085 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008086
8087 This is controlled by the configure argument ``--with-universal-archs``:
8088
8089 - ``--with-universal-archs=all``: install 4-way universal
8090
8091 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8092
8093 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8094
8095 This option should be used in combination with ``--enable-universalsdk=``.
8096
8097 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008146- Issue #1631171: Re-implement the 'warnings' module in C (the
8147 original Python code has been kept as backup). This will allow for
8148 using the 'warning's machinery in such places as the parser where
8149 use of pure Python code is not possible. Both the ``showarning()``
8150 and ``formatwarning()`` gain an optional 'line' argument which is
8151 not called by default for backwards-compatibility reasons. Setting
8152 ``warnings.showwarning()`` to an implementation that lacks support
8153 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008216- Issue #2550: The approach used by client/server code for obtaining
8217 ports to listen on in network-oriented tests has been refined in an
8218 effort to facilitate running multiple instances of the entire
8219 regression test suite in parallel without issue.
8220 test_support.bind_port() has been fixed such that it will always
8221 return a unique port -- which wasn't always the case with the
8222 previous implementation, especially if socket options had been set
8223 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8224 new implementation of bind_port() will actually raise an exception
8225 if it is passed an AF_INET/SOCK_STREAM socket with either the
8226 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8227 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8228 the socket it's been passed. This currently only applies to
8229 Windows. This option prevents any other sockets from binding to the
8230 host/port we've bound to, thus removing the possibility of the
8231 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8232 when a second SOCK_STREAM socket binds and accepts to a host/port
8233 that's already been bound by another socket. The optional preferred
8234 port parameter to bind_port() has been removed. Under no
8235 circumstances should tests be hard coding ports!
8236
8237 test_support.find_unused_port() has also been introduced, which will
8238 pass a temporary socket object to bind_port() in order to obtain an
8239 unused port. The temporary socket object is then closed and
8240 deleted, and the port is returned. This method should only be used
8241 for obtaining an unused port in order to pass to an external program
8242 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8243 a parameter to a server-oriented class that doesn't give you direct
8244 access to the underlying socket used.
8245
8246 Finally, test_support.HOST has been introduced, which should be used
8247 for the host argument of any relevant socket calls (i.e. bind and
8248 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008249
8250 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008251 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008252 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8253 test_asynchat and test_socket_ssl.
8254
Georg Brandl3ee81df2008-05-17 18:14:43 +00008255 It is now possible for multiple instances of the regression test
8256 suite to run in parallel without issue.

8523-----------------
8524
Fred Drakea8ee94b2008-03-01 02:45:07 +00008525- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008526 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008527
Georg Brandlad61bc82008-02-23 15:11:18 +00008528- Issue #2067: file.__exit__() now calls subclasses' close() method.
8529
8530- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008531
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008532- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008533 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008534
Eric Smitha73fbe72008-02-23 03:09:44 +00008535- Added the future_builtins module, which contains hex() and oct().
8536 These are the PEP 3127 version of these functions, designed to be
8537 compatible with the hex() and oct() builtins from Python 3.0. They
8538 differ slightly in their output formats from the existing, unchanged
8539 Python 2.6 builtins. The expected usage of the future_builtins
8540 module is:
8541 from future_builtins import hex, oct
8542
Eric Smith7ef40bf2008-02-20 23:34:22 +00008543- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8544 exponents for exponents with absolute value < 100. Follows C99
8545 standard. This is a change on Windows, which would use 3 digits.
8546 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8547 so that any alterations it does to the resulting string will be
8548 available in stringlib/formatter.h (for float.__format__).
8549
Eric Smith5a3c1352008-02-19 13:21:56 +00008550- Implemented PEP 3101, Advanced String Formatting. This adds a new
8551 builtin format(); a format() method for str and unicode; a
8552 __format__() method to object, str, unicode, int, long, float, and
8553 datetime; the class string.Formatter; and the C API
8554 PyObject_Format().
8555
Georg Brandl3ee81df2008-05-17 18:14:43 +00008556- Fixed several potential crashes, all caused by specially crafted
8557 __del__ methods exploiting objects in temporarily inconsistent
8558 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008559
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008560- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008561 prevent a possible crash: an Abstract Base Class would try to access
8562 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008563
Georg Brandl3ee81df2008-05-17 18:14:43 +00008564- Fixed repr() and str() of complex numbers with infinity or nan as
8565 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008566
Georg Brandl3ee81df2008-05-17 18:14:43 +00008567- Clear all free lists during a gc.collect() of the highest generation
8568 in order to allow pymalloc to free more arenas. Python may give back
8569 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008570
Georg Brandl3ee81df2008-05-17 18:14:43 +00008571- Issue #2045: Fix an infinite recursion triggered when printing a
8572 subclass of collections.defaultdict, if its default_factory is set
8573 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008574
Christian Heimesf75dbef2008-02-08 00:11:31 +00008575- Fixed a minor memory leak in dictobject.c. The content of the free
8576 list was not freed on interpreter shutdown.
8577
Georg Brandl21e99f42010-03-07 15:23:59 +00008578- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008579 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008580
Georg Brandl3ee81df2008-05-17 18:14:43 +00008581- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8582 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008583 to compact the internal free lists of pre-allocted ints and floats.
8584
Georg Brandl3ee81df2008-05-17 18:14:43 +00008585- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8586 calls. Python expected the return type int but the fork familie
8587 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008588
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8590 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008591
Georg Brandl3ee81df2008-05-17 18:14:43 +00008592- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8593 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008594
Georg Brandl3ee81df2008-05-17 18:14:43 +00008595- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8596 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008597
Georg Brandl3ee81df2008-05-17 18:14:43 +00008598- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8599 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008600
Georg Brandl3ee81df2008-05-17 18:14:43 +00008601- Patch #1473257: generator objects gain a gi_code attribute. This is
8602 the same object as the func_code attribute of the function that
8603 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008604
Georg Brandl3ee81df2008-05-17 18:14:43 +00008605- Issue #1920: "while 0" statements were completely removed by the
8606 compiler, even in the presence of an "else" clause, which is
8607 supposed to be run when the condition is false. Now the compiler
8608 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008609
Guido van Rossumeead05f2008-01-24 18:21:02 +00008610- A few crashers fixed: weakref_in_del.py (issue #1377858);
8611 loosing_dict_ref.py (issue #1303614, test67.py);
8612 borrowed_ref_[34].py (not in tracker).
8613
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008614- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008615 suppressed while an extension is loaded by calling SetErrorMode in
8616 dynload_win.c. The error is still reported properly.
8617
Georg Brandl3ee81df2008-05-17 18:14:43 +00008618- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008619 several extension methods and modules do not work without unicode
8620 support.
8621
Georg Brandl26543b12008-01-21 18:36:51 +00008622- Issue #1882: when compiling code from a string, encoding cookies in the
8623 second line of code were not always recognized correctly.
8624
Georg Brandl14404b62008-01-19 19:27:05 +00008625- Issue #1679: "0x" was taken as a valid integer literal.
8626
Georg Brandl6caad7d2008-01-26 14:19:22 +00008627- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008628 added.
8629
Christian Heimesc94e2b52008-01-14 04:13:37 +00008630- sys.float_info / PyFloat_GetInfo: The floating point information
8631 object was converted from a dict to a specialized structseq object.
8632
Georg Brandl3ee81df2008-05-17 18:14:43 +00008633- Patch #1816: Added sys.flags structseq. It exposes the status of
8634 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008635
Georg Brandl3ee81df2008-05-17 18:14:43 +00008636- Objects/structseq.c: Implemented new structseq representation. The
8637 patch makes structseqs (e.g. the return value of os.stat) more
8638 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008639
Georg Brandl3ee81df2008-05-17 18:14:43 +00008640- Patch #1700288: added a type attribute cache that caches method
8641 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008642
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008643- Bug #1776: __import__() no longer accepts filenames on any platform.
8644 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008645
Georg Brandlaed6c662008-01-07 17:25:53 +00008646- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8647
Georg Brandl3ee81df2008-05-17 18:14:43 +00008648- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8649 envvar and sys.dont_write_bytecode attribute. All these can be set
8650 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008651
Georg Brandl3ee81df2008-05-17 18:14:43 +00008652- Improve some exception messages when Windows fails to load an
8653 extension module. Now we get for example '%1 is not a valid Win32
8654 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008655
Georg Brandl3ee81df2008-05-17 18:14:43 +00008656- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008658- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8659 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008660
Christian Heimes0a8143f2007-12-18 23:22:54 +00008661- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008662 and INF. float("nan"), float("inf") and float("-inf") now work on
8663 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008664
Georg Brandl3ee81df2008-05-17 18:14:43 +00008665- Compiler now generates simpler and faster code for dictionary
8666 literals. The oparg for BUILD_MAP now indicates an estimated
8667 dictionary size. There is a new opcode, STORE_MAP, for adding
8668 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008669
Georg Brandl3ee81df2008-05-17 18:14:43 +00008670- Issue #1638: %zd configure test fails on Linux.

8680
Nick Coghlanef01d822007-12-03 12:55:17 +00008681- PEP 366: Allow explicit relative imports when executing modules
8682 inside packages with the -m switch via a new module level
8683 __package__ attribute.
8684
Georg Brandl3ee81df2008-05-17 18:14:43 +00008685- Issue #1402: Fix a crash on exit, when another thread is still
8686 running, and if the deallocation of its frames somehow calls the
8687 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008688

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008692 attribute of an empty cell object.
8693
Georg Brandl3ee81df2008-05-17 18:14:43 +00008694- Issue #1460: The utf-7 incremental decoder did not accept truncated
8695 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008696
Georg Brandl3ee81df2008-05-17 18:14:43 +00008697- Patch #1739468: Directories and zipfiles containing a __main__.py
8698 file can now be directly executed by passing their name to the
8699 interpreter. The directory/zipfile is automatically inserted as the
8700 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008701
Georg Brandl3ee81df2008-05-17 18:14:43 +00008702- Issue #1265: Fix a problem with sys.settrace, if the tracing
8703 function uses a generator expression when at the same time the
8704 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008705
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008706- sets and frozensets now have an isdisjoint() method.
8707
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008708- optimize the performance of builtin.sum().
8709
Neal Norwitz44f326e2007-10-05 05:29:17 +00008710- Fix warnings found by the new version of the Coverity checker.
8711
Georg Brandl21e99f42010-03-07 15:23:59 +00008712- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008713 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8714 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008715
Georg Brandl3ee81df2008-05-17 18:14:43 +00008716- Issue #1686386: Tuple's tp_repr did not take into account the
8717 possibility of having a self-referential tuple, which is possible
8718 from C code. Nor did object's tp_str consider that a type's tp_str
8719 could do something that could lead to an inifinite recursion.
8720 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8721 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008722
Georg Brandl3ee81df2008-05-17 18:14:43 +00008723- Issue #1164: It was possible to trigger deadlock when using the
8724 'print' statement to write to a file since the GIL was not released
8725 as needed. Now PyObject_Print() does the right thing along with
8726 various tp_print implementations of the built-in types and those in
8727 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008728
Georg Brandl3ee81df2008-05-17 18:14:43 +00008729- Issue #1147: Exceptions were directly allowing string exceptions in
8730 their throw() method even though string exceptions no longer
8731 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008732
Georg Brandl3ee81df2008-05-17 18:14:43 +00008733- Issue #1096: Prevent a segfault from getting the repr of a very
8734 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008735
Brett Cannon1e534b52007-09-07 04:18:30 +00008736- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008737 PyObject_Call() never calling back out to Python code to trigger
8738 recursion depth updates/checks. Required the creation of a static
8739 RuntimeError instance in case normalizing an exception put the
8740 recursion check value past its limit. Fixes crashers
8741 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008742
Georg Brandl3ee81df2008-05-17 18:14:43 +00008743- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008756- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008757 __*__ attributes. (Some already existed, e.g., __doc__ and
8758 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00008767 "except E as target:". This is to provide forwards compatibility
8768 with Python 3.0.

8788
Guido van Rossum143b5642007-03-23 04:58:42 +00008789- Bug #1683368: The object.__init__() and object.__new__() methods are
8790 now stricter in rejecting excess arguments. The only time when
8791 either allows excess arguments is when it is not overridden and the
8792 other one is. For backwards compatibility, when both are
8793 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008794 warning later). Also, type.__init__() insists on the same signature
8795 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008796
Georg Brandl3ee81df2008-05-17 18:14:43 +00008797- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8798 object to complex using its __complex__() method before falling back
8799 to the __float__() method. Therefore, the functions in the cmath
8800 module now can operate on objects that define a __complex__()
8801 method.

8818
Georg Brandl7b9c5552007-03-12 14:30:05 +00008819- Bug #1678647: write a newline after printing an exception in any
8820 case, even when converting the value to a string failed.
8821
Georg Brandl871f1bc2007-03-12 13:17:36 +00008822- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008823 its argument, if it exists. If not, it will work like before. This
8824 allows customizing the output of dir() in the presence of a
8825 __getattr__().

8835 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008836
Georg Brandlaa2321b2007-03-07 00:40:28 +00008837- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008838 makes the filenames the warning module prints much more sensible
8839 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008852- Patch #1674228: when assigning a slice (old-style), check for the
8853 sq_ass_slice instead of the sq_slice slot.
8854
Georg Brandl3ee81df2008-05-17 18:14:43 +00008855- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00009480- unittest now verifies more of its assumptions. In particular,
9481 TestCase and TestSuite subclasses (not instances) are no longer
9482 accepted in TestSuite.addTest(). This should cause no
9483 incompatibility since it never made sense with ordinary subclasses
9484 -- the failure just occurred later, with a more cumbersome
9485 exception.

9758 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009759
Georg Brandl3ee81df2008-05-17 18:14:43 +00009760- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9761 with RFC 3207 and forgets any knowledge obtained from the server not
9762 obtained from the TLS negotiation itself. Patch contributed by Bill
9763 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009764
Georg Brandl3ee81df2008-05-17 18:14:43 +00009765- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009766 that the SMTP.starttls() caller no longer needs to call ehlo()
9767 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009768 does not claim to support starttls. Adds the
9769 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9850 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9851 silently miscode subclasses of those types. Now, it raises a
9852 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009853

Georg Brandl3ee81df2008-05-17 18:14:43 +00009868 time so that opening a database previously created with the DB_DUP
9869 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9870 opens. Specifically: dictionary assignment to a DB object will
9871 replace all values for a given key when the database allows
9872 duplicate values. DB users should use DB.put(k, v) when they want
9873 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009874

9880 characters with ASCII value less than 32. Also, it correctly quotes
9881 dots only if they occur on a single line, as opposed to the previous
9882 behavior of quoting dots if they are the second character of any
9883 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009884

10212
Georg Brandl3ee81df2008-05-17 18:14:43 +000010213- Unified naming convention for free lists and their limits. All free
10214 lists in Object/ are named ``free_list``, the counter ``numfree``
10215 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10216 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010217
Georg Brandl3ee81df2008-05-17 18:14:43 +000010218- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10219 to ``PyTuple_SetItem``, it can be used to populate a brand new
10220 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010221
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010222- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010223
Georg Brandl3ee81df2008-05-17 18:14:43 +000010224- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10225 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10226 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010227
10228- Patch #1720595: add T_BOOL to the range of structmember types.
10229
10230- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10231 ``PyFloat_GetInfo()`` to the float API.
10232
Georg Brandl3ee81df2008-05-17 18:14:43 +000010233- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10234 of w# format code incorrectly truncated the length to an int, even
10235 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10236 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010237
Georg Brandl3ee81df2008-05-17 18:14:43 +000010238- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10239 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010240
Georg Brandl3ee81df2008-05-17 18:14:43 +000010241- PEP 3123: Provide forward compatibility with Python 3.0, while
10242 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10243 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010244
Georg Brandl3ee81df2008-05-17 18:14:43 +000010245- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10246 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010247
10248- Patch #1733960: Allow T_LONGLONG to accept ints.
10249
10250- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10251
Christian Heimes000a0742008-01-03 22:16:32 +000010252- Added a new API function ``PyImport_ImportModuleNoBlock``.
10253
Georg Brandl6caad7d2008-01-26 14:19:22 +000010254- Bug #1637022: Prefix AST symbols with _Py_.
10255
10256- Fix some leftovers from the conversion from int to Py_ssize_t
10257 (relevant to strings and sequences of more than 2**31 items).
10258
10259- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10260 outside of pystate.c and should not be necessary.
10261
Georg Brandl3ee81df2008-05-17 18:14:43 +000010262- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10263 absolute imports. In earlier versions they might have used relative
10264 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010265
Georg Brandl3ee81df2008-05-17 18:14:43 +000010266- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10267 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010268
Georg Brandl3ee81df2008-05-17 18:14:43 +000010269- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10270 macro so it can be used as an expression.

10274
Georg Brandl3ee81df2008-05-17 18:14:43 +000010275- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10276 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10277 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10278 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010279
Georg Brandl3ee81df2008-05-17 18:14:43 +000010280- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10281 _CRT_NONSTDC_NO_DEPRECATE.
Martin v. Löwis2607e6c2006-11-21 18:20:25 +000010282

Brett Cannon791d56f2007-05-31 19:40:42 +000010290- buildtools now raises a DeprecationWarning.
10291
Georg Brandl3ee81df2008-05-17 18:14:43 +000010292- Removed the macfs module. It had been deprecated since Python 2.5.
10293 This lead to the deprecation of macostools.touched() as it relied
10294 solely on macfs and was a no-op under OS X.
