641
642- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
643 and later systems as is currently done for Python 3.x installers.
644 For 2.7.7 only, we will provide three installers:
645 the legacy deprecated 10.3+ 32-bit-only format;
646 the newer 10.5+ 32-bit-only format;
647 and the unchanged 10.6+ 64-/32-bit format.
648 Although binary installers will no longer be available from
649 python.org as of 2.7.8, it will still be possible to build from
650 source on 10.3.9 and 10.4 systems if necessary.
651 See Mac/BuildScript/README.txt for more information.

2031 OS X 10.8, 10.7, and optionally 10.6).
2032 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2033 * Since Xcode 4 removes ppc support, extension module builds now
2034 check for ppc compiler support and by default remove ppc and
2035 ppc64 archs when they are not available.
2036 * Extension module builds now revert to using system installed
2037 headers and libs (/usr and /System/Library) if the SDK used
2038 to build the interpreter is not installed or has moved.
2039 * Try to avoid building extension modules with deprecated
2040 and problematic Apple llvm-gcc compiler. If original compiler
2041 is not available, use clang instead by default.

2378
Mark Hammond323b5da2011-10-17 11:05:36 +11002379- Issue #7833: Extension modules built using distutils on Windows will no
2380 longer include a "manifest" to prevent them failing at import time in some
2381 embedded situations.
2382
Benjamin Petersona7b09762011-10-15 13:43:21 -04002383- Issue #13186: Fix __delitem__ on old-style instances when invoked through

2391
Mark Dickinsondbbed042011-09-19 16:38:08 +01002392- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2393 int.__pow__. These overflow checks were causing int.__pow__ to produce
2394 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002395 compiler optimizing the check away. Also fix similar overflow checks
2396 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2397 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02002408- Issue #12149: Update the method cache after a type's dictionnary gets
2409 cleared by the garbage collector. This fixes a segfault when an instance
2410 and its type get caught in a reference cycle, and the instance's
2411 deallocator calls one of the methods on the type (e.g. when subclassing
2412 IOBase). Diagnosis and patch by Davide Rizzo.
2413
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01002414- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02002421 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2422 raw_input() interrupted by CTRL+c.
2423
Łukasz Langa7a153902011-10-18 17:16:00 +02002424- Issue #10860: httplib now correctly handles an empty port after port
2425 delimiter in URLs.
2426

Florent Xiclunac2279652012-02-12 14:49:03 +01002465- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002466 has left two versions of customize_compiler, the original in
2467 distutils.sysconfig and another copy in distutils.ccompiler, with some
2468 parts of distutils calling one and others using the other.
2469 Complete the revert back to only having one in distutils.sysconfig as
2470 is the case in 3.x.
2471
Ned Deily0d0ea482012-02-10 12:59:06 +01002472- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2473 Distutils-based packages with C extension modules may fail because
2474 Apple has removed gcc-4.2, the version used to build python.org
2475 64-bit/32-bit Pythons. If the user does not explicitly override
2476 the default C compiler by setting the CC environment variable,
2477 Distutils will now attempt to compile extension modules with clang
2478 if gcc-4.2 is required but not found. Also as a convenience, if
2479 the user does explicitly set CC, substitute its value as the default
2480 compiler in the Distutils LDSHARED configuration variable for OS X.
2481 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2482 SDK, neither of which are available in Xcode 4. This change does not
2483 attempt to override settings to support their use with Xcode 4.)
2484

Senthil Kumaran607e31e2012-02-09 17:43:31 +08002487- Issue #6005: Examples in the socket library documentation use sendall, where
2488 relevant, instead send method.
2489
Petri Lehtinenc7fd5232011-05-09 12:24:09 +02002490- Issue #10811: Fix recursive usage of cursors. Instead of crashing,

2492

Ned Deily87e82bb2011-06-28 19:52:59 -07002733- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2734 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2735 interpreter process. This could cause failures in non-Distutils subprocesses
2736 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002737 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002738 deployment target only in the environment of each build subprocess. It is
2739 still possible to globally override the default by setting
2740 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2741 greater or equal to the default value, the value with which the interpreter
2742 was built.

2771 updating the check interval, so if the user decreases the check interval,
2772 the ticker doesn't have to wind down to zero from the old starting point
2773 before the new interval takes effect. And if the user increases the
2774 interval, it makes sure the new limit takes effect right away rather have an
2775 early task switch before recognizing the new interval.

3756 This prevents user-created self-referencing ordered dictionaries from
3757 becoming permanently uncollectable GC garbage. The downside is that

4217
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004218- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4219 start byte and the continuation byte(s) are now considered invalid, instead
4220 of the number of bytes specified by the start byte.
4221 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4222 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4223 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4224 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004232- Issue #8748: Fix two issues with comparisons between complex and integer
4233 objects. (1) The comparison could incorrectly return True in some cases
4234 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4235 (2) The comparison raised an OverflowError for large integers, leading
4236 to unpredictable exceptions when combining integers and complex objects
4237 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004239- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004376- Issue #1533: Fix inconsistency in range function argument processing: any
4377 non-float non-integer argument is now converted to an integer (if possible)
4378 using its __int__ method. Previously, only small arguments were treated this

Georg Brandlfee0f442010-05-22 21:26:21 +00004430- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4431 operation raises multiple signals and more than one of those signals is
4432 trapped, the specification determines the order in which the signals should be
4433 handled. In many cases this order wasn't being followed, leading to the wrong
4434 Python exception being raised.

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004600
4601Core and Builtins
4602-----------------
4603
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004604- Issue #7301: Add environment variable $PYTHONWARNINGS.
4605
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004606- Issue #8329: Don't return the same lists from select.select when no fds are
4607 changed.
4608
Georg Brandlfee0f442010-05-22 21:26:21 +00004609- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004610 on 64-bit machines. The shift count for either left or right shift is
4611 permitted to be up to sys.maxsize.
4612
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004613- Ensure that tokenization of identifiers is not affected by locale.
4614
Georg Brandlfee0f442010-05-22 21:26:21 +00004615- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004616
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004617- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4618
Georg Brandlfee0f442010-05-22 21:26:21 +00004619- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4620 with a non-empty format string. This is an effort to future-proof user
4621 code. If a derived class does not currently implement __format__ but later
4622 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004623 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004624 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004625
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004626- Issue #8268: Old-style classes (not just instances) now support weak
4627 references.
4628
Georg Brandlfee0f442010-05-22 21:26:21 +00004629- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4630 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004631
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004632- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00004634- Issue #6474: Make error message from passing an inadequate number of keyword
4635 arguments to a function correct.
4636
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004637- Issue #8164: Don't allow lambda functions to have a docstring.
4638
Victor Stinner66644262010-03-10 22:30:19 +00004639- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004640 (SIGINT). If an error occurs while importing the site module, the error is
4641 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004642 module.
4643
Collin Winter001a3952010-03-18 21:54:01 +00004644- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00004649- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4650
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004651- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004652 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4653 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004654
Benjamin Peterson76a23c12010-04-04 23:23:22 +00004655- Issue #8310: Allow dis to examine new style classes.
4656
Georg Brandlfee0f442010-05-22 21:26:21 +00004657- Issue #8257: The Decimal construct now accepts a float instance directly,
4658 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004659
4660 >>> Decimal(1.1)
4661 Decimal('1.100000000000000088817841970012523233890533447265625')
4662
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004663- collections.Counter() now supports a subtract() method.
4664
Georg Brandlfee0f442010-05-22 21:26:21 +00004665- The functools module now has a total_ordering() class decorator to simplify
4666 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004667
Georg Brandlfee0f442010-05-22 21:26:21 +00004668- The functools module also adds cmp_to_key() as a tool to transition old-style
4669 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004670
Georg Brandlfee0f442010-05-22 21:26:21 +00004671- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4672 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004673
Georg Brandlfee0f442010-05-22 21:26:21 +00004674- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4675 InvalidOperation instead of returning False. (Comparisons involving a quiet
4676 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4677 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004678
Georg Brandlfee0f442010-05-22 21:26:21 +00004679- Issue #2531: Comparison operations between floats and Decimal instances now
4680 return a result based on the numeric values of the operands; previously they
4681 returned an arbitrary result based on the relative ordering of id(float) and
4682 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004683
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004684- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004685 argument `-` which tells it to read files to compile from stdin. Each line is
4686 read on demand and the named file is compiled immediately. (Original patch by
4687 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004688
Georg Brandlfee0f442010-05-22 21:26:21 +00004689- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4690 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004692- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4693 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004694 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004695
Georg Brandlfee0f442010-05-22 21:26:21 +00004696- Comparisons using one of <, <=, >, >= between a complex instance and a
4697 Fractions instance now raise TypeError instead of returning True/False. This
4698 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4699 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004700
Michael Foorde6410c52010-03-29 20:04:23 +00004701- Addition of ``WeakSet`` to the ``weakref`` module.

4709
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004710- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004711 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4712 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004713
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004714- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4715 deprecated.
4716
Georg Brandlfee0f442010-05-22 21:26:21 +00004717- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4718 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004719

4724 existing at the same time, causing a Unicode error when configuration code
4725 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004726
Georg Brandlfee0f442010-05-22 21:26:21 +00004727- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4728 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00004729
Antoine Pitroueee91cd2010-03-26 19:27:16 +00004730- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
4731 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4732 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00004733
Florent Xiclunacf82fa62010-03-21 12:27:20 +00004734- Issue #8179: Fix macpath.realpath() on a non-existing path.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004754- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004755 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4756 log file to compute the next rollover time. If the log file does not exist,
4757 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004758

Georg Brandlba83f822010-03-14 09:50:54 +00004767- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4768 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4769 This is a behavior change, so email's minor version number is now bumped, to
4770 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004798- Issue #8300: When passing a non-integer argument to struct.pack with any
4799 integer format code, struct.pack first attempts to convert the non-integer
4800 using its __index__ method. If that method is non-existent or raises
4801 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +00004803- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4804 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4805 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004806 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4807 inconsistent: __int__ was used for some integer codes but not for others, and
4808 the set of integer codes for which it was used differed between native packing
4809 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005061- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5062 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5063 returning NULL. The macro now returns a statically allocated empty string

5213Core and Builtins
5214-----------------
5215
Georg Brandlba83f822010-03-14 09:50:54 +00005216- The ``__complex__()`` method is now looked up on the class of instances to
5217 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005218
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005219- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5220 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5221
Mark Dickinson1b34d252010-01-01 17:27:30 +00005222- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005223 DeprecationWarning when passed a float argument where an integer was expected.
5224 These functions and methods now raise TypeError instead. The majority of the
5225 effects of this change are in the extension modules, but some core functions
5226 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5227 and many unicode/str methods.

5238 used to drop the time part of the result.
5239
Georg Brandlba83f822010-03-14 09:50:54 +00005240- Issue #1811: Improve accuracy and cross-platform consistency for true division
5241 of integers: the result of a/b is now correctly rounded for ints a and b (at
5242 least on IEEE 754 platforms), and in particular does not depend on the
5243 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005244
Georg Brandlba83f822010-03-14 09:50:54 +00005245- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
5246 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
5247 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00005248

Ronald Oussoren92919a62009-12-24 13:30:58 +00005250 executables on OSX.
5251
Georg Brandlba83f822010-03-14 09:50:54 +00005252 These executables now work properly with the arch(1) command: ``arch -ppc
5253 python`` will start a universal binary version of python in PPC mode (unlike
5254 previous releases).

5392 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5393 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005394
Georg Brandlba83f822010-03-14 09:50:54 +00005395- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5396 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005397
Georg Brandlba83f822010-03-14 09:50:54 +00005398- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5399 1e-100 used to raise OverflowError, but now gives the requested 120
5400 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005408
Georg Brandlba83f822010-03-14 09:50:54 +00005409- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5410 decimal string that's guaranteed to round back to x under correct rounding
5411 (with round-half-to-even rounding mode). Previously it gave a string based on
5412 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5413 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5414 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005415
Georg Brandlba83f822010-03-14 09:50:54 +00005416- Issue #7117: On almost all platforms: float-to-string and string-to-float
5417 conversions within Python are now correctly rounded. Places these conversions
5418 occur include: str for floats and complex numbers; the float and complex
5419 constructors; old-style and new-style numeric formatting; serialization and
5420 deserialization of floats and complex numbers using marshal, pickle and json;
5421 parsing of float and imaginary literals in Python code; Decimal-to-float
5422 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005423
Georg Brandlba83f822010-03-14 09:50:54 +00005424 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5425 providing correctly-rounded strtod and dtoa C functions. This code is
5426 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5427 the C compiler. There may be a small number of platforms on which correct
5428 operation of this code cannot be guaranteed, so the code is not used: notably,
5429 this applies to platforms where the C double format is not IEEE 754 binary64,
5430 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5431 and Python's configure script is unable to determine how to change the FPU
5432 precision. On these platforms conversions use the platform strtod and dtoa,
5433 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005434
Georg Brandlba83f822010-03-14 09:50:54 +00005435- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5436 uses the correctly-rounded string <-> float conversions described above (when
5437 available), and so produces correctly rounded results that will display nicely
5438 under the float repr. There are two related small changes: (1) round now
5439 accepts any class with an ``__index__()`` method for its second argument (but
5440 no longer accepts floats for the second argument), and (2) an excessively
5441 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5442 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005584
Georg Brandlba83f822010-03-14 09:50:54 +00005585 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5586 (2) parsing of strings representing infinities and nans was locale aware; and
5587 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00005588
Georg Brandlba83f822010-03-14 09:50:54 +00005589- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5590 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5591 but with at least one decimal point and with a default precision
5592 of 12. Previously, the behavior the same but with a default precision of 6.
5593 This more closely matches ``str()``, and reduces surprises when adding
5594 alignment flags to the empty presentation type. This also affects the new
5595 complex.__format__ in the same way.
5596
5597- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5598 classtype's, even if it was None. property now inserts the __doc__ into the

5669 internal representation of integers, for performance reasons. Base 2**30 is
5670 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00005758- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00005759 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00005760
Skip Montanarof205c132008-12-23 03:30:15 +00005761- Added test case to ensure attempts to read from a file opened for writing
5762 fail.
5763
Georg Brandlba83f822010-03-14 09:50:54 +00005764- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
5765 elapsed times, not only when some objects are uncollectable/unreachable.
5766 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00005767
Mark Dickinson1a707982008-12-17 16:14:37 +00005768- Issue #3439: Add a bit_length method to int and long.
5769
Georg Brandlba83f822010-03-14 09:50:54 +00005770- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
5771 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00005772
Georg Brandlba83f822010-03-14 09:50:54 +00005773- Issue #4597: Fixed exception handling when the __exit__ function of a context
5774 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00005775
Georg Brandlba83f822010-03-14 09:50:54 +00005776- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00005777
Georg Brandlba83f822010-03-14 09:50:54 +00005778- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5779 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5780 instances. On a typical machine this saves 3 bytes of memory (on average) per
5781 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00005782
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005783- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5784 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5785 instead of throwing a MemoryError.
5786
Georg Brandlba83f822010-03-14 09:50:54 +00005787- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5788 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005789
Benjamin Petersonc078f922008-11-21 22:27:24 +00005790- Issue #4367: Python would segfault during compiling when the unicodedata
5791 module couldn't be imported and \N escapes were present.
5792
Georg Brandlba83f822010-03-14 09:50:54 +00005793- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5794 file objects with closefd=False. The file descriptor is still kept open but
5795 the file object behaves like a closed file. The ``FileIO`` object also got a
5796 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005797
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005798- Issue #4348: Some bytearray methods returned that didn't cause any change to
5799 the bytearray, returned the same bytearray instead of a copy.
5800
Georg Brandlba83f822010-03-14 09:50:54 +00005801- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00005803- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
5804
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005805- Issue #4048: The parser module now correctly validates relative imports.
5806
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005807- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
5808 exec statement.
5809
Georg Brandlba83f822010-03-14 09:50:54 +00005810- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
5811 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00005812
Benjamin Petersonbdca9422008-10-26 20:21:13 +00005813- Issue #4209: Enabling unicode_literals and the print_function in the same
5814 __future__ import didn't work.
5815
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005816- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005817 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005818
Georg Brandlba83f822010-03-14 09:50:54 +00005819- On windows, ``os.chdir()`` given unicode was not working if
5820 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5821 this code path is really executed because I cannot move to such directory on
5822 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005823
Georg Brandlba83f822010-03-14 09:50:54 +00005824- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5825 element is temporarily replaced with an equivalent frozenset. But the
5826 eventual KeyError would always report the empty ``frozenset()`` as the missing
5827 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005828
Georg Brandlba83f822010-03-14 09:50:54 +00005829- Issue #4509: Various issues surrounding resize of bytearray objects to which
5830 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00005831
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00005832- Issue #4748: Lambda generators no longer return a value.

5835
Gregory P. Smithae91d092009-03-02 05:13:57 +00005836- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
5837
Georg Brandlba83f822010-03-14 09:50:54 +00005838- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
5839 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00005840
Matthias Klose91a3b9e2009-04-05 21:19:13 +00005841- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
5842 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00005843
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005844- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5845 returned them on 64bit platforms.
5846
Walter Dörwalded960ac2009-05-03 22:36:33 +00005847- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5848 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5849 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5850 of using the replace error handler in PyUnicode_DecodeUTF8().
5851
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005852- Issue #3739: The unicode-internal encoder now reports the number of characters
5853 consumed like any other encoder (instead of the number of bytes).
5854
Georg Brandlba83f822010-03-14 09:50:54 +00005855- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5856 allocator will be automatically disabled when running under Valgrind. This
5857 gives improved memory leak detection when running under Valgrind, while taking
5858 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00005883- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
5884 ownership when the group is not forced, because the group may be different
5885 from the user's group and inherit from its container when the test is run.

7028 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7029 neither __int__ nor __long__, TypeError used to be raised (with a
7030 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
7031 struct.error in other cases.

7034 argument with an __int__ method can be packed, but use of this feature

7227
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007228- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7229 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7230 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7231 ``printf`` function, whereas PyString_FromFormat has an independent
7232 implementation and uses "%zd" on all platforms for size_t values.
7233 This makes a difference on win64, where ``printf`` needs "%Id" to display
7234 64bit values.

7240 object; previously an int would be returned for small values. the __long__
7241 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007251 was correctly parsed but parsing of subsequent arguments failed.
7252
Vinay Sajip35e3b032008-09-01 14:33:59 +00007253- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007254 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7255 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7256 when given a tuple of classes as second argument, were looking up
7257 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7258 type object.

7404
Guido van Rossumf8402962008-08-20 15:01:50 +00007405- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7406 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7407 extensions do not automatically benefit from the class attribute
7408 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7409 to their tp_flags field if they care. This is a backwards
7410 compatibility feature; in 3.0, all types will use the cache by
7411 default.
7412
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007413- Keyword arguments can now follow starred arguments. (``f(a, *args,

7424 object was stored in the freelist.
7425
Mark Dickinsonb6467572008-08-04 21:30:09 +00007426- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7427 ValueError consistently across platforms.
7428
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007429- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7430 (64bit Unix, for example), unichr() would truncate its argument and return
7431 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7432
Neal Norwitze7d8be82008-07-31 17:17:14 +00007433- Apply security patches from Apple.
7434
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007435- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7436 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7437
Antoine Pitrou92f82162008-07-25 22:22:08 +00007438- Issue #1819: function calls with several named parameters are now on
7439 average 35% faster (as measured by pybench).
7440
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007441- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7442 the python debugger steps into a class statement: the free variables (local
7443 variables defined in an outer scope) would be deleted from the outer scope.
7444
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007445- Issue #2620: Overflow checking when allocating or reallocating memory
7446 was not always being done properly in some python types and extension
7447 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7448 all been updated to perform better checks and places in the code that
7449 would previously leak memory on the error path when such an allocation
7450 failed have been fixed.

7456
Benjamin Petersone977ad42008-08-20 01:42:01 +00007457- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7458 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7459
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007460- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7461 version reported by these tools does not necessarily follow the python
7462 version numbering scheme, so the module is less strict when parsing it.
7463
Nick Coghlanf70385a2008-08-18 12:42:46 +00007464- Issue #2235: Added Py3k warnings for types which will become unhashable
7465 under the stricter __hash__ inheritance rules in 3.0. Several types
7466 which did not meet the rules for hash invariants and were already
7467 unhashable in 3.0 have now been explicitly flagged as unhashable in
7468 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7469 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7470
Brett Cannon88f801d2008-08-18 00:46:22 +00007471- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00007502- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7503 since mimetools itself is deprecated. Because modules are cached, all
7504 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7505
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007506- Issue #3134: shutil referenced undefined WindowsError symbol.

7515 a MemoryError rather than silently stop the iteration.
7516
Guido van Rossum59ce9012008-08-09 14:55:34 +00007517- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7518 to _sre.compile() will now be rejected. This should not affect anybody
7519 since the re.compile() function never generates invalid re-bytecode.
7520
Skip Montanaroa032bf42008-08-08 22:52:51 +00007521- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7522 upon first access it can be automatically initialized from the csv file if
7523 it wasn't initialized during instantiation.
7524
Brett Cannon3aa2a492008-08-06 22:28:09 +00007525- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7526 the reload() built-in has been removed.
7527
Brett Cannon7e30b672008-08-04 21:52:25 +00007528- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007540 asking for a specific length. This problem only affected files opened
7541 using the new "io" module, not the built-in open() function.

7567 file name rather than a ZipInfo instance, so files are extracted with
7568 mode 0600 rather than 000 under Unix.
7569
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007570- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7571 argument in python 2.5, this broke code that subclassed Popen to include its

7583 interaction with the tp_hash slot (added in 2.6b2) are now documented
7584
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007585- Issue #643841: The language reference now provides more detailed
7586 coverage of the lookup process for special methods. The disclaimers
7587 regarding lack of coverage of new-style classes have also been
7588 removed, since the coverage is now fairly reasonable.

7592================================
7593
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007594*Release date: 17-Jul-2008*
7595
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007596Core and Builtins
7597-----------------
7598
Georg Brandl3e483f62008-07-16 22:57:41 +00007599- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7600 its methods now allow for items objects that can be converted to
7601 an integer using operator.index().
7602
Mark Dickinson64b7e502008-07-16 09:40:03 +00007603- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7604 produced a ValueError instead of giving the correct float.
7605
Eric Smitha5fa5a22008-07-16 00:11:49 +00007606- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7607 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7608
Mark Dickinson7103aa42008-07-15 19:08:33 +00007609- Issue #3008: the float type has a new instance method 'float.hex'
7610 and a new class method 'float.fromhex' to convert floating-point
7611 numbers to and from hexadecimal strings, respectively.
7612
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007613- Issue #2235: __hash__ is once again inherited by default. To allow
7614 collections.Hashable to remain meaningful in the presence of the
7615 default hash implementation (object.__hash__), it is now possible
7616 to explicit block inheritance of hash by setting __hash__=None at
7617 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7618 level.
7619
Nick Coghlanb028f502008-07-13 14:52:36 +00007620- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7621 the parent module cannot be found while performing an absolute import.
7622 This means that an incorrectly defined __package__ attribute will
7623 now only prevent relative imports in that module rather than causing
7624 all imports from that module to fail.
7625
Nick Coghlan14ff9942008-07-08 14:21:42 +00007626- Issue #2517: Allow unicode messages in Exceptions again by correctly
7627 bypassing the instance dictionary when looking up __unicode__ on
7628 new-style classes.
7629
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007630- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7631 set to a custom object whose write() method happens to install
7632 another file in sys.stdout.
7633
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007634- Issue #3088: Corrected a race condition in classes derived from
7635 threading.local: the first member set by a thread could be saved in
7636 another thread's dictionary.
7637
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007638- Issue #3004: Minor change to slice.indices(): the start and stop
7639 arguments are now treated identically, making the behaviour easier
7640 to describe and understand. For example, slice(None, -10,
7641 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7642 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7643 10, -1).
7644
Georg Brandl278fc502008-07-19 12:46:12 +00007645- Issue #3219: Calling a function with repeated keyword arguments,
7646 f(a=2, a=23), would not cause a syntax error. This was a regression
7647 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007648
Georg Brandl278fc502008-07-19 12:46:12 +00007649- Issue #2862: Make int and float freelist management consistent with
7650 other freelists. Changes their CompactFreeList apis into
7651 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007652

7654-------
7655
Thomas Heller57adf222008-08-14 19:10:48 +00007656- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7657 api functions without holding the GIL, which could lead to a fatal
7658 error when they failed.
7659
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007660- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7669 ForkingPickler.register() to resolve conflict with ctypes.
7670
Vinay Sajip51e65192008-07-18 09:01:10 +00007671- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007672
Thomas Heller880f5292008-07-15 19:39:38 +00007673- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7674 a valid dlerror() message.
7675
Thomas Heller2bad6572008-07-15 17:19:50 +00007676- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7677 incomplete structure was created.
7678
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007679- Issue #3339: dummy_thread.acquire() should not return None.

7682
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007683- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007684
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007685- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7686 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007687 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007688 content-length. The problem had been corrected in the 2.4 branch, but never
7689 merged into trunk.
7690
Georg Brandle78fbcc2008-07-05 10:13:36 +00007691- Issue #2663: add filtering capability to shutil.copytree().

8094 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008095 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008096
8097 This is controlled by the configure argument ``--with-universal-archs``:
8098
8099 - ``--with-universal-archs=all``: install 4-way universal
8100
8101 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8102
8103 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8104
8105 This option should be used in combination with ``--enable-universalsdk=``.
8106
8107 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 +00008156- Issue #1631171: Re-implement the 'warnings' module in C (the
8157 original Python code has been kept as backup). This will allow for
8158 using the 'warning's machinery in such places as the parser where
8159 use of pure Python code is not possible. Both the ``showarning()``
8160 and ``formatwarning()`` gain an optional 'line' argument which is
8161 not called by default for backwards-compatibility reasons. Setting
8162 ``warnings.showwarning()`` to an implementation that lacks support
8163 for the ``line`` argument will raise a DeprecationWarning.

8187
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008188- The getpass module has been improved on Unix. It now uses /dev/tty
8189 by default and uses stderr instead of stdout. A GetPassWarning is
8190 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008226- Issue #2550: The approach used by client/server code for obtaining
8227 ports to listen on in network-oriented tests has been refined in an
8228 effort to facilitate running multiple instances of the entire
8229 regression test suite in parallel without issue.
8230 test_support.bind_port() has been fixed such that it will always
8231 return a unique port -- which wasn't always the case with the
8232 previous implementation, especially if socket options had been set
8233 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8234 new implementation of bind_port() will actually raise an exception
8235 if it is passed an AF_INET/SOCK_STREAM socket with either the
8236 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8237 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8238 the socket it's been passed. This currently only applies to
8239 Windows. This option prevents any other sockets from binding to the
8240 host/port we've bound to, thus removing the possibility of the
8241 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8242 when a second SOCK_STREAM socket binds and accepts to a host/port
8243 that's already been bound by another socket. The optional preferred
8244 port parameter to bind_port() has been removed. Under no
8245 circumstances should tests be hard coding ports!
8246
8247 test_support.find_unused_port() has also been introduced, which will
8248 pass a temporary socket object to bind_port() in order to obtain an
8249 unused port. The temporary socket object is then closed and
8250 deleted, and the port is returned. This method should only be used
8251 for obtaining an unused port in order to pass to an external program
8252 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8253 a parameter to a server-oriented class that doesn't give you direct
8254 access to the underlying socket used.
8255
8256 Finally, test_support.HOST has been introduced, which should be used
8257 for the host argument of any relevant socket calls (i.e. bind and
8258 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008259
8260 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008262 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8263 test_asynchat and test_socket_ssl.

8532Core and builtins
8533-----------------
8534
Fred Drakea8ee94b2008-03-01 02:45:07 +00008535- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008536 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008537
Georg Brandlad61bc82008-02-23 15:11:18 +00008538- Issue #2067: file.__exit__() now calls subclasses' close() method.
8539
8540- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008541
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008542- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008543 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008544
Eric Smitha73fbe72008-02-23 03:09:44 +00008545- Added the future_builtins module, which contains hex() and oct().
8546 These are the PEP 3127 version of these functions, designed to be
8547 compatible with the hex() and oct() builtins from Python 3.0. They
8548 differ slightly in their output formats from the existing, unchanged
8549 Python 2.6 builtins. The expected usage of the future_builtins
8550 module is:
8551 from future_builtins import hex, oct
8552
Eric Smith7ef40bf2008-02-20 23:34:22 +00008553- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8554 exponents for exponents with absolute value < 100. Follows C99
8555 standard. This is a change on Windows, which would use 3 digits.
8556 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8557 so that any alterations it does to the resulting string will be
8558 available in stringlib/formatter.h (for float.__format__).
8559
Eric Smith5a3c1352008-02-19 13:21:56 +00008560- Implemented PEP 3101, Advanced String Formatting. This adds a new
8561 builtin format(); a format() method for str and unicode; a
8562 __format__() method to object, str, unicode, int, long, float, and
8563 datetime; the class string.Formatter; and the C API
8564 PyObject_Format().
8565
Georg Brandl3ee81df2008-05-17 18:14:43 +00008566- Fixed several potential crashes, all caused by specially crafted
8567 __del__ methods exploiting objects in temporarily inconsistent
8568 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008569
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008570- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008571 prevent a possible crash: an Abstract Base Class would try to access
8572 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008573
Georg Brandl3ee81df2008-05-17 18:14:43 +00008574- Fixed repr() and str() of complex numbers with infinity or nan as
8575 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008576
Georg Brandl3ee81df2008-05-17 18:14:43 +00008577- Clear all free lists during a gc.collect() of the highest generation
8578 in order to allow pymalloc to free more arenas. Python may give back
8579 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008580
Georg Brandl3ee81df2008-05-17 18:14:43 +00008581- Issue #2045: Fix an infinite recursion triggered when printing a
8582 subclass of collections.defaultdict, if its default_factory is set
8583 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008584
Christian Heimesf75dbef2008-02-08 00:11:31 +00008585- Fixed a minor memory leak in dictobject.c. The content of the free
8586 list was not freed on interpreter shutdown.
8587
Georg Brandl21e99f42010-03-07 15:23:59 +00008588- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008590
Georg Brandl3ee81df2008-05-17 18:14:43 +00008591- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8592 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008593 to compact the internal free lists of pre-allocted ints and floats.
8594
Georg Brandl3ee81df2008-05-17 18:14:43 +00008595- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8596 calls. Python expected the return type int but the fork familie
8597 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008598
Georg Brandl3ee81df2008-05-17 18:14:43 +00008599- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8600 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008601
Georg Brandl3ee81df2008-05-17 18:14:43 +00008602- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8603 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008604
Georg Brandl3ee81df2008-05-17 18:14:43 +00008605- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8606 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008607
Georg Brandl3ee81df2008-05-17 18:14:43 +00008608- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8609 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008610
Georg Brandl3ee81df2008-05-17 18:14:43 +00008611- Patch #1473257: generator objects gain a gi_code attribute. This is
8612 the same object as the func_code attribute of the function that
8613 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008614
Georg Brandl3ee81df2008-05-17 18:14:43 +00008615- Issue #1920: "while 0" statements were completely removed by the
8616 compiler, even in the presence of an "else" clause, which is
8617 supposed to be run when the condition is false. Now the compiler
8618 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008619
Guido van Rossumeead05f2008-01-24 18:21:02 +00008620- A few crashers fixed: weakref_in_del.py (issue #1377858);
8621 loosing_dict_ref.py (issue #1303614, test67.py);
8622 borrowed_ref_[34].py (not in tracker).
8623
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008624- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008625 suppressed while an extension is loaded by calling SetErrorMode in
8626 dynload_win.c. The error is still reported properly.
8627
Georg Brandl3ee81df2008-05-17 18:14:43 +00008628- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008629 several extension methods and modules do not work without unicode
8630 support.
8631
Georg Brandl26543b12008-01-21 18:36:51 +00008632- Issue #1882: when compiling code from a string, encoding cookies in the
8633 second line of code were not always recognized correctly.
8634
Georg Brandl14404b62008-01-19 19:27:05 +00008635- Issue #1679: "0x" was taken as a valid integer literal.
8636
Georg Brandl6caad7d2008-01-26 14:19:22 +00008637- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008638 added.
8639
Christian Heimesc94e2b52008-01-14 04:13:37 +00008640- sys.float_info / PyFloat_GetInfo: The floating point information
8641 object was converted from a dict to a specialized structseq object.
8642
Georg Brandl3ee81df2008-05-17 18:14:43 +00008643- Patch #1816: Added sys.flags structseq. It exposes the status of
8644 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008645
Georg Brandl3ee81df2008-05-17 18:14:43 +00008646- Objects/structseq.c: Implemented new structseq representation. The
8647 patch makes structseqs (e.g. the return value of os.stat) more
8648 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008649
Georg Brandl3ee81df2008-05-17 18:14:43 +00008650- Patch #1700288: added a type attribute cache that caches method
8651 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008652
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008653- Bug #1776: __import__() no longer accepts filenames on any platform.
8654 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008655
Georg Brandlaed6c662008-01-07 17:25:53 +00008656- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8657
Georg Brandl3ee81df2008-05-17 18:14:43 +00008658- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8659 envvar and sys.dont_write_bytecode attribute. All these can be set
8660 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008661
Georg Brandl3ee81df2008-05-17 18:14:43 +00008662- Improve some exception messages when Windows fails to load an
8663 extension module. Now we get for example '%1 is not a valid Win32
8664 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008665
Georg Brandl3ee81df2008-05-17 18:14:43 +00008666- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008668- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8669 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008670
Christian Heimes0a8143f2007-12-18 23:22:54 +00008671- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008672 and INF. float("nan"), float("inf") and float("-inf") now work on
8673 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008674
Georg Brandl3ee81df2008-05-17 18:14:43 +00008675- Compiler now generates simpler and faster code for dictionary
8676 literals. The oparg for BUILD_MAP now indicates an estimated
8677 dictionary size. There is a new opcode, STORE_MAP, for adding
8678 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008679
Georg Brandl3ee81df2008-05-17 18:14:43 +00008680- Issue #1638: %zd configure test fails on Linux.

8690
Nick Coghlanef01d822007-12-03 12:55:17 +00008691- PEP 366: Allow explicit relative imports when executing modules
8692 inside packages with the -m switch via a new module level
8693 __package__ attribute.
8694
Georg Brandl3ee81df2008-05-17 18:14:43 +00008695- Issue #1402: Fix a crash on exit, when another thread is still
8696 running, and if the deallocation of its frames somehow calls the
8697 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008698

8708 file can now be directly executed by passing their name to the
8709 interpreter. The directory/zipfile is automatically inserted as the
8710 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008711
Georg Brandl3ee81df2008-05-17 18:14:43 +00008712- Issue #1265: Fix a problem with sys.settrace, if the tracing
8713 function uses a generator expression when at the same time the
8714 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008715
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008716- sets and frozensets now have an isdisjoint() method.
8717
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008718- optimize the performance of builtin.sum().
8719
Neal Norwitz44f326e2007-10-05 05:29:17 +00008720- Fix warnings found by the new version of the Coverity checker.
8721
Georg Brandl21e99f42010-03-07 15:23:59 +00008722- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008723 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8724 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008725
Georg Brandl3ee81df2008-05-17 18:14:43 +00008726- Issue #1686386: Tuple's tp_repr did not take into account the
8727 possibility of having a self-referential tuple, which is possible
8728 from C code. Nor did object's tp_str consider that a type's tp_str
8729 could do something that could lead to an inifinite recursion.
8730 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8731 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008732
Georg Brandl3ee81df2008-05-17 18:14:43 +00008733- Issue #1164: It was possible to trigger deadlock when using the
8734 'print' statement to write to a file since the GIL was not released
8735 as needed. Now PyObject_Print() does the right thing along with
8736 various tp_print implementations of the built-in types and those in
8737 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008738
Georg Brandl3ee81df2008-05-17 18:14:43 +00008739- Issue #1147: Exceptions were directly allowing string exceptions in
8740 their throw() method even though string exceptions no longer
8741 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008742

Brett Cannon1e534b52007-09-07 04:18:30 +00008746- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008747 PyObject_Call() never calling back out to Python code to trigger
8748 recursion depth updates/checks. Required the creation of a static
8749 RuntimeError instance in case normalizing an exception put the
8750 recursion check value past its limit. Fixes crashers
8751 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008766- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008767 __*__ attributes. (Some already existed, e.g., __doc__ and
8768 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008769
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008770- Add -3 option to the interpreter to warn about features that are

8774 calls.
8775
Collin Winter62903052007-05-18 23:11:24 +00008776- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008777 "except E as target:". This is to provide forwards compatibility
8778 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008779
Brett Cannon229cee22007-05-05 01:34:02 +00008780- Deprecate BaseException.message as per PEP 352.
8781
Georg Brandl3ee81df2008-05-17 18:14:43 +00008782- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008783 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008785- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008786 setting a plain string, ie don't expand to single letter identifiers.
8787
Raymond Hettinger13936692007-04-11 18:40:58 +00008788- Request #1191699: Slices can now be pickled.
8789
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008790- Request #1193128: str.translate() now allows a None argument for
8791 translations that only remove characters without re-mapping the
8792 remaining characters.
8793
Georg Brandl5cb76c12007-03-21 09:00:39 +00008794- Patch #1682205: a TypeError while unpacking an iterable is no longer

8798
Guido van Rossum143b5642007-03-23 04:58:42 +00008799- Bug #1683368: The object.__init__() and object.__new__() methods are
8800 now stricter in rejecting excess arguments. The only time when
8801 either allows excess arguments is when it is not overridden and the
8802 other one is. For backwards compatibility, when both are
8803 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008804 warning later). Also, type.__init__() insists on the same signature
8805 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008806
Georg Brandl3ee81df2008-05-17 18:14:43 +00008807- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8808 object to complex using its __complex__() method before falling back
8809 to the __float__() method. Therefore, the functions in the cmath
8810 module now can operate on objects that define a __complex__()
8811 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008812
Georg Brandl3ee81df2008-05-17 18:14:43 +00008813- Patch #1623563: allow __class__ assignment for classes with
8814 __slots__. The old and the new class are still required to have the
8815 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008816

8828
Georg Brandl7b9c5552007-03-12 14:30:05 +00008829- Bug #1678647: write a newline after printing an exception in any
8830 case, even when converting the value to a string failed.
8831
Georg Brandl871f1bc2007-03-12 13:17:36 +00008832- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008833 its argument, if it exists. If not, it will work like before. This
8834 allows customizing the output of dir() in the presence of a
8835 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008836
Collin Winter276887b2007-03-12 16:11:39 +00008837- Patch #922167: Python no longer segfaults when faced with infinitely
8838 self-recursive reload() calls (as reported by bug #742342).

8844 parthensized forms. This means complex(repr(x)) now works instead of
8845 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008846
Georg Brandlaa2321b2007-03-07 00:40:28 +00008847- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008848 makes the filenames the warning module prints much more sensible
8849 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008850
Georg Brandl49aafc92007-03-07 00:34:46 +00008851- Variant of patch #697613: don't exit the interpreter on a SystemExit
8852 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008853 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00008862- Patch #1674228: when assigning a slice (old-style), check for the
8863 sq_ass_slice instead of the sq_slice slot.
8864
Georg Brandl3ee81df2008-05-17 18:14:43 +00008865- When printing an unraisable error, don't print exceptions. before
8866 the name. This duplicates the behavior whening normally printing
8867 exceptions.

9489
Georg Brandl3ee81df2008-05-17 18:14:43 +00009490- unittest now verifies more of its assumptions. In particular,

9492 accepted in TestSuite.addTest(). This should cause no
9493 incompatibility since it never made sense with ordinary subclasses
9494 -- the failure just occurred later, with a more cumbersome
9495 exception.

9773 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009774
Georg Brandl3ee81df2008-05-17 18:14:43 +00009775- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009776 that the SMTP.starttls() caller no longer needs to call ehlo()
9777 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009778 does not claim to support starttls. Adds the
9779 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9860 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9861 silently miscode subclasses of those types. Now, it raises a
9862 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009863

Georg Brandl3ee81df2008-05-17 18:14:43 +00009878 time so that opening a database previously created with the DB_DUP
9879 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9880 opens. Specifically: dictionary assignment to a DB object will
9881 replace all values for a given key when the database allows
9882 duplicate values. DB users should use DB.put(k, v) when they want
9883 to store duplicates; not DB[k] = v.

9890 characters with ASCII value less than 32. Also, it correctly quotes
9891 dots only if they occur on a single line, as opposed to the previous
9892 behavior of quoting dots if they are the second character of any
9893 line.

10221-----
10222
Georg Brandl3ee81df2008-05-17 18:14:43 +000010223- Unified naming convention for free lists and their limits. All free
10224 lists in Object/ are named ``free_list``, the counter ``numfree``
10225 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10226 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010227
Georg Brandl3ee81df2008-05-17 18:14:43 +000010228- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10229 to ``PyTuple_SetItem``, it can be used to populate a brand new
10230 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010231
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010232- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010233
Georg Brandl3ee81df2008-05-17 18:14:43 +000010234- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10235 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10236 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010237
10238- Patch #1720595: add T_BOOL to the range of structmember types.
10239
10240- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10241 ``PyFloat_GetInfo()`` to the float API.
10242
Georg Brandl3ee81df2008-05-17 18:14:43 +000010243- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10244 of w# format code incorrectly truncated the length to an int, even
10245 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10246 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010247
Georg Brandl3ee81df2008-05-17 18:14:43 +000010248- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10249 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010250
Georg Brandl3ee81df2008-05-17 18:14:43 +000010251- PEP 3123: Provide forward compatibility with Python 3.0, while
10252 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10253 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010254
Georg Brandl3ee81df2008-05-17 18:14:43 +000010255- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10256 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010257
10258- Patch #1733960: Allow T_LONGLONG to accept ints.
10259
10260- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10261
Christian Heimes000a0742008-01-03 22:16:32 +000010262- Added a new API function ``PyImport_ImportModuleNoBlock``.
10263
Georg Brandl6caad7d2008-01-26 14:19:22 +000010264- Bug #1637022: Prefix AST symbols with _Py_.
10265
10266- Fix some leftovers from the conversion from int to Py_ssize_t
10267 (relevant to strings and sequences of more than 2**31 items).
10268
10269- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10270 outside of pystate.c and should not be necessary.
10271
Georg Brandl3ee81df2008-05-17 18:14:43 +000010272- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10273 absolute imports. In earlier versions they might have used relative
10274 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010275
Georg Brandl3ee81df2008-05-17 18:14:43 +000010276- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10277 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010278
Georg Brandl3ee81df2008-05-17 18:14:43 +000010279- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10280 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010285- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10286 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10287 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10288 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010289
Georg Brandl3ee81df2008-05-17 18:14:43 +000010290- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
10291 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +000010300- buildtools now raises a DeprecationWarning.
10301
Georg Brandl3ee81df2008-05-17 18:14:43 +000010302- Removed the macfs module. It had been deprecated since Python 2.5.
10303 This lead to the deprecation of macostools.touched() as it relied
10304 solely on macfs and was a no-op under OS X.
