1198
1199- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1200 and later systems as is currently done for Python 3.x installers.
1201 For 2.7.7 only, we will provide three installers:
1202 the legacy deprecated 10.3+ 32-bit-only format;
1203 the newer 10.5+ 32-bit-only format;
1204 and the unchanged 10.6+ 64-/32-bit format.
1205 Although binary installers will no longer be available from
1206 python.org as of 2.7.8, it will still be possible to build from
1207 source on 10.3.9 and 10.4 systems if necessary.
1208 See Mac/BuildScript/README.txt for more information.

2590 32-bit-only installer Pythons on systems with Xcode 4 (currently
2591 OS X 10.8, 10.7, and optionally 10.6).
2592 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2593 * Since Xcode 4 removes ppc support, extension module builds now
2594 check for ppc compiler support and by default remove ppc and
2595 ppc64 archs when they are not available.
2596 * Extension module builds now revert to using system installed
2597 headers and libs (/usr and /System/Library) if the SDK used
2598 to build the interpreter is not installed or has moved.
2599 * Try to avoid building extension modules with deprecated
2600 and problematic Apple llvm-gcc compiler. If original compiler
2601 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003038- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003039 has left two versions of customize_compiler, the original in
3040 distutils.sysconfig and another copy in distutils.ccompiler, with some
3041 parts of distutils calling one and others using the other.
3042 Complete the revert back to only having one in distutils.sysconfig as
3043 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01003045- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3046 Distutils-based packages with C extension modules may fail because
3047 Apple has removed gcc-4.2, the version used to build python.org
3048 64-bit/32-bit Pythons. If the user does not explicitly override
3049 the default C compiler by setting the CC environment variable,
3050 Distutils will now attempt to compile extension modules with clang
3051 if gcc-4.2 is required but not found. Also as a convenience, if
3052 the user does explicitly set CC, substitute its value as the default
3053 compiler in the Distutils LDSHARED configuration variable for OS X.
3054 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3055 SDK, neither of which are available in Xcode 4. This change does not
3056 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003306- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3307 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3308 interpreter process. This could cause failures in non-Distutils subprocesses
3309 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003310 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003311 deployment target only in the environment of each build subprocess. It is
3312 still possible to globally override the default by setting
3313 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3314 greater or equal to the default value, the value with which the interpreter
3315 was built.

3344 updating the check interval, so if the user decreases the check interval,
3345 the ticker doesn't have to wind down to zero from the old starting point
3346 before the new interval takes effect. And if the user increases the
3347 interval, it makes sure the new limit takes effect right away rather have an
3348 early task switch before recognizing the new interval.

3855 accepted by ``time.mktime`` and ``time.strftime`` is still system
3856 dependent, but ``time.mktime`` will now accept full range supported
3857 by the OS. Conversion of 2-digit years to 4-digit is deprecated.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00004190- Issue #9869: Make long() and PyNumber_Long return something of type
4191 long for a class whose __long__ method returns a plain int. This
4192 fixes an interpreter crash when initializing an instance of a long
4193 subclass from an object whose __long__ method returns a plain int.

4198 thread-local storage key.
4199
Victor Stinnercaafd772010-09-08 10:51:01 +00004200- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
4201 encoding and errors attributes instead of using utf-8 in strict mode, to get
4202 the same behaviour than the print statement.
4203
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00004204- Issue #9737: Fix a crash when trying to delete a slice or an item from

4218
4219 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
4220 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Antoine Pitroue4195e82010-09-12 14:56:27 +00004342- Issue #9837: The read() method of ZipExtFile objects (as returned by

4344
Raymond Hettinger20397532010-09-12 02:11:45 +00004345- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4346 This prevents user-created self-referencing ordered dictionaries from
4347 becoming permanently uncollectable GC garbage. The downside is that
4348 removing __del__ means that the internal doubly-linked list has to wait for
4349 GC collection rather than freeing memory immediately when the refcnt drops
4350 to zero.
4351

4355
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004356- Issue #9792: In case of connection failure, socket.create_connection()
4357 would swallow the exception and raise a new one, making it impossible
4358 to fetch the original errno, or to filter timeout errors. Now the
4359 original error is re-raised.

4380
R. David Murray7c4bf552010-08-25 01:45:57 +00004381- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4382 character years even if the message contains RFC822 two character years.

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004416- Issue #9550: a BufferedReader could issue an additional read when the

4419 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004808- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4809 start byte and the continuation byte(s) are now considered invalid, instead
4810 of the number of bytes specified by the start byte.
4811 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4812 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4813 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4814 Previous versions returned a single u'\ufffd'.

4823 objects. (1) The comparison could incorrectly return True in some cases
4824 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4825 (2) The comparison raised an OverflowError for large integers, leading

5210 with a non-empty format string. This is an effort to future-proof user
5211 code. If a derived class does not currently implement __format__ but later
5212 adds its own __format__, it would most likely break user code that had

Georg Brandlfee0f442010-05-22 21:26:21 +00005264- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5265 InvalidOperation instead of returning False. (Comparisons involving a quiet
5266 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5267 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00005269- Issue #2531: Comparison operations between floats and Decimal instances now
5270 return a result based on the numeric values of the operands; previously they
5271 returned an arbitrary result based on the relative ordering of id(float) and
5272 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00005275 argument `-` which tells it to read files to compile from stdin. Each line is
5276 read on demand and the named file is compiled immediately. (Original patch by
5277 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00005286- Comparisons using one of <, <=, >, >= between a complex instance and a
5287 Fractions instance now raise TypeError instead of returning True/False. This
5288 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5289 <=> complex, and complex <=> complex comparisons.

5389 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00005393- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5394 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5395 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005396 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5397 inconsistent: __int__ was used for some integer codes but not for others, and
5398 the set of integer codes for which it was used differed between native packing
5399 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005707 file position when calling `truncate()`. It would previously change the file
5708 position to the given argument, which goes against the tradition of

5712 class used to represent files stored inside an archive. The new
5713 implementation is significantly faster and can be wrapped in a
5714 ``io.BufferedReader`` object for more speedups. It also solves an issue
5715 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5804-----------------
5805
Georg Brandlba83f822010-03-14 09:50:54 +00005806- The ``__complex__()`` method is now looked up on the class of instances to
5807 make it consistent with other special methods.

5811
Mark Dickinson1b34d252010-01-01 17:27:30 +00005812- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005813 DeprecationWarning when passed a float argument where an integer was expected.
5814 These functions and methods now raise TypeError instead. The majority of the
5815 effects of this change are in the extension modules, but some core functions
5816 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5817 and many unicode/str methods.

5982 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5983 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005984
Georg Brandlba83f822010-03-14 09:50:54 +00005985- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5986 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00005988- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5989 1e-100 used to raise OverflowError, but now gives the requested 120
5990 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005998
Georg Brandlba83f822010-03-14 09:50:54 +00005999- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6000 decimal string that's guaranteed to round back to x under correct rounding
6001 (with round-half-to-even rounding mode). Previously it gave a string based on
6002 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6003 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6004 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006005
Georg Brandlba83f822010-03-14 09:50:54 +00006006- Issue #7117: On almost all platforms: float-to-string and string-to-float
6007 conversions within Python are now correctly rounded. Places these conversions
6008 occur include: str for floats and complex numbers; the float and complex
6009 constructors; old-style and new-style numeric formatting; serialization and
6010 deserialization of floats and complex numbers using marshal, pickle and json;
6011 parsing of float and imaginary literals in Python code; Decimal-to-float
6012 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006013
Georg Brandlba83f822010-03-14 09:50:54 +00006014 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6015 providing correctly-rounded strtod and dtoa C functions. This code is
6016 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6017 the C compiler. There may be a small number of platforms on which correct
6018 operation of this code cannot be guaranteed, so the code is not used: notably,
6019 this applies to platforms where the C double format is not IEEE 754 binary64,
6020 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6021 and Python's configure script is unable to determine how to change the FPU
6022 precision. On these platforms conversions use the platform strtod and dtoa,
6023 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006024
Georg Brandlba83f822010-03-14 09:50:54 +00006025- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6026 uses the correctly-rounded string <-> float conversions described above (when
6027 available), and so produces correctly rounded results that will display nicely
6028 under the float repr. There are two related small changes: (1) round now
6029 accepts any class with an ``__index__()`` method for its second argument (but
6030 no longer accepts floats for the second argument), and (2) an excessively
6031 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6032 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00006174
Georg Brandlba83f822010-03-14 09:50:54 +00006175 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
6176 (2) parsing of strings representing infinities and nans was locale aware; and
6177 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00006179- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6180 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6181 but with at least one decimal point and with a default precision
6182 of 12. Previously, the behavior the same but with a default precision of 6.
6183 This more closely matches ``str()``, and reduces surprises when adding
6184 alignment flags to the empty presentation type. This also affects the new
6185 complex.__format__ in the same way.
6186
6187- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
6188 classtype's, even if it was None. property now inserts the __doc__ into the
6189 subclass instance __dict__.

6259 internal representation of integers, for performance reasons. Base 2**30 is
6260 enabled by default on 64-bit machines. Add --enable-big-digits option to

7638 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
7639 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7640 neither __int__ nor __long__, TypeError used to be raised (with a
7641 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
7642 struct.error in other cases.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007837- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7838
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007839- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7840 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7841 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7842 ``printf`` function, whereas PyString_FromFormat has an independent
7843 implementation and uses "%zd" on all platforms for size_t values.
7844 This makes a difference on win64, where ``printf`` needs "%Id" to display
7845 64bit values.
7846
Benjamin Peterson97179b02008-09-09 20:55:01 +00007847- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7848 error.
7849
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007850- Issue #3777: long() applied to a float object now always return a long
7851 object; previously an int would be returned for small values. the __long__
7852 method is allowed to return either an int or a long, but the behaviour of
7853 float objects should not change to respect backward compatibility.
7854
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007855- Issue #3751: str.rpartition would perform a left-partition when called with
7856 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007861 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007862 was correctly parsed but parsing of subsequent arguments failed.
7863
Vinay Sajip35e3b032008-09-01 14:33:59 +00007864- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007865 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7866 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7867 when given a tuple of classes as second argument, were looking up
7868 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7869 type object.
7870
Neal Norwitz18aa3882008-08-24 05:04:52 +00007871- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007940 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7941 for catch_warnings() also led to an improvement in the raising of a

8014-----------------
8015
Guido van Rossumf8402962008-08-20 15:01:50 +00008016- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8017 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8018 extensions do not automatically benefit from the class attribute
8019 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8020 to their tp_flags field if they care. This is a backwards
8021 compatibility feature; in 3.0, all types will use the cache by
8022 default.
8023
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008024- Keyword arguments can now follow starred arguments. (``f(a, *args,
8025 keyword=23)`` is now valid syntax.)
8026
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008027- ctypes function pointers that are COM methods have a boolean True
8028 value again.
8029
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008030- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8031 by denying s# to parse objects that have a releasebuffer procedure,
8032 and introducing s*.
8033
Georg Brandl1e13ea92008-08-11 09:07:59 +00008034- Issue #3537: Fix an assertion failure when an empty but presized dict
8035 object was stored in the freelist.
8036
Mark Dickinsonb6467572008-08-04 21:30:09 +00008037- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8038 ValueError consistently across platforms.
8039
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008040- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8041 (64bit Unix, for example), unichr() would truncate its argument and return
8042 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8043
Neal Norwitze7d8be82008-07-31 17:17:14 +00008044- Apply security patches from Apple.
8045
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008046- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8047 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8048
Antoine Pitrou92f82162008-07-25 22:22:08 +00008049- Issue #1819: function calls with several named parameters are now on
8050 average 35% faster (as measured by pybench).
8051
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008052- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8053 the python debugger steps into a class statement: the free variables (local
8054 variables defined in an outer scope) would be deleted from the outer scope.
8055
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008056- Issue #2620: Overflow checking when allocating or reallocating memory
8057 was not always being done properly in some python types and extension
8058 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8059 all been updated to perform better checks and places in the code that
8060 would previously leak memory on the error path when such an allocation
8061 failed have been fixed.

8067
Benjamin Petersone977ad42008-08-20 01:42:01 +00008068- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8069 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8070
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008071- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8072 version reported by these tools does not necessarily follow the python
8073 version numbering scheme, so the module is less strict when parsing it.
8074
Nick Coghlanf70385a2008-08-18 12:42:46 +00008075- Issue #2235: Added Py3k warnings for types which will become unhashable
8076 under the stricter __hash__ inheritance rules in 3.0. Several types
8077 which did not meet the rules for hash invariants and were already
8078 unhashable in 3.0 have now been explicitly flagged as unhashable in
8079 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

8195
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008196- Issue #643841: The language reference now provides more detailed

8208-----------------
8209
Georg Brandl3e483f62008-07-16 22:57:41 +00008210- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8211 its methods now allow for items objects that can be converted to
8212 an integer using operator.index().
8213
Mark Dickinson64b7e502008-07-16 09:40:03 +00008214- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8215 produced a ValueError instead of giving the correct float.
8216
Eric Smitha5fa5a22008-07-16 00:11:49 +00008217- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8218 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8219
Mark Dickinson7103aa42008-07-15 19:08:33 +00008220- Issue #3008: the float type has a new instance method 'float.hex'
8221 and a new class method 'float.fromhex' to convert floating-point
8222 numbers to and from hexadecimal strings, respectively.
8223
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008224- Issue #2235: __hash__ is once again inherited by default. To allow
8225 collections.Hashable to remain meaningful in the presence of the
8226 default hash implementation (object.__hash__), it is now possible
8227 to explicit block inheritance of hash by setting __hash__=None at
8228 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8229 level.
8230
Nick Coghlanb028f502008-07-13 14:52:36 +00008231- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8232 the parent module cannot be found while performing an absolute import.
8233 This means that an incorrectly defined __package__ attribute will
8234 now only prevent relative imports in that module rather than causing
8235 all imports from that module to fail.
8236
Nick Coghlan14ff9942008-07-08 14:21:42 +00008237- Issue #2517: Allow unicode messages in Exceptions again by correctly

8247 another thread's dictionary.
8248
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008249- Issue #3004: Minor change to slice.indices(): the start and stop
8250 arguments are now treated identically, making the behaviour easier
8251 to describe and understand. For example, slice(None, -10,
8252 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8253 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8254 10, -1).
8255
Georg Brandl278fc502008-07-19 12:46:12 +00008256- Issue #3219: Calling a function with repeated keyword arguments,
8257 f(a=2, a=23), would not cause a syntax error. This was a regression
8258 from 2.4 caused by the switch to the new compiler.

8297 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008298 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008299 content-length. The problem had been corrected in the 2.4 branch, but never

8703
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008704- On MacOS X it is now possible to install the framework in 64-bit
8705 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008706 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008707
8708 This is controlled by the configure argument ``--with-universal-archs``:
8709
8710 - ``--with-universal-archs=all``: install 4-way universal
8711
8712 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8713
8714 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8715
8716 This option should be used in combination with ``--enable-universalsdk=``.
8717
8718 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 +00008767- Issue #1631171: Re-implement the 'warnings' module in C (the
8768 original Python code has been kept as backup). This will allow for
8769 using the 'warning's machinery in such places as the parser where
8770 use of pure Python code is not possible. Both the ``showarning()``
8771 and ``formatwarning()`` gain an optional 'line' argument which is
8772 not called by default for backwards-compatibility reasons. Setting
8773 ``warnings.showwarning()`` to an implementation that lacks support
8774 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008837- Issue #2550: The approach used by client/server code for obtaining
8838 ports to listen on in network-oriented tests has been refined in an
8839 effort to facilitate running multiple instances of the entire
8840 regression test suite in parallel without issue.
8841 test_support.bind_port() has been fixed such that it will always
8842 return a unique port -- which wasn't always the case with the
8843 previous implementation, especially if socket options had been set
8844 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8845 new implementation of bind_port() will actually raise an exception
8846 if it is passed an AF_INET/SOCK_STREAM socket with either the
8847 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8848 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8849 the socket it's been passed. This currently only applies to
8850 Windows. This option prevents any other sockets from binding to the
8851 host/port we've bound to, thus removing the possibility of the
8852 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8853 when a second SOCK_STREAM socket binds and accepts to a host/port
8854 that's already been bound by another socket. The optional preferred
8855 port parameter to bind_port() has been removed. Under no
8856 circumstances should tests be hard coding ports!
8857
8858 test_support.find_unused_port() has also been introduced, which will
8859 pass a temporary socket object to bind_port() in order to obtain an
8860 unused port. The temporary socket object is then closed and
8861 deleted, and the port is returned. This method should only be used
8862 for obtaining an unused port in order to pass to an external program
8863 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8864 a parameter to a server-oriented class that doesn't give you direct
8865 access to the underlying socket used.
8866
8867 Finally, test_support.HOST has been introduced, which should be used
8868 for the host argument of any relevant socket calls (i.e. bind and
8869 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008870
8871 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008872 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008873 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8874 test_asynchat and test_socket_ssl.
8875
Georg Brandl3ee81df2008-05-17 18:14:43 +00008876 It is now possible for multiple instances of the regression test
8877 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00008931- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00008932 \Uxxxxxxxx did not accept values outside the Basic Multilingual
8933 Plane. This affected raw unicode literals and the
8934 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
8935 this case, like normal unicode literals and the 'unicode-escape'
8936 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00009156- Added the future_builtins module, which contains hex() and oct().
9157 These are the PEP 3127 version of these functions, designed to be
9158 compatible with the hex() and oct() builtins from Python 3.0. They
9159 differ slightly in their output formats from the existing, unchanged
9160 Python 2.6 builtins. The expected usage of the future_builtins
9161 module is:
9162 from future_builtins import hex, oct
9163
Eric Smith7ef40bf2008-02-20 23:34:22 +00009164- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9165 exponents for exponents with absolute value < 100. Follows C99
9166 standard. This is a change on Windows, which would use 3 digits.
9167 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9168 so that any alterations it does to the resulting string will be
9169 available in stringlib/formatter.h (for float.__format__).
9170
Eric Smith5a3c1352008-02-19 13:21:56 +00009171- Implemented PEP 3101, Advanced String Formatting. This adds a new
9172 builtin format(); a format() method for str and unicode; a
9173 __format__() method to object, str, unicode, int, long, float, and
9174 datetime; the class string.Formatter; and the C API
9175 PyObject_Format().
9176
Georg Brandl3ee81df2008-05-17 18:14:43 +00009177- Fixed several potential crashes, all caused by specially crafted
9178 __del__ methods exploiting objects in temporarily inconsistent
9179 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009180
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009181- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009182 prevent a possible crash: an Abstract Base Class would try to access
9183 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009184

Georg Brandl3ee81df2008-05-17 18:14:43 +00009188- Clear all free lists during a gc.collect() of the highest generation
9189 in order to allow pymalloc to free more arenas. Python may give back
9190 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009191
Georg Brandl3ee81df2008-05-17 18:14:43 +00009192- Issue #2045: Fix an infinite recursion triggered when printing a
9193 subclass of collections.defaultdict, if its default_factory is set
9194 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009222- Patch #1473257: generator objects gain a gi_code attribute. This is
9223 the same object as the func_code attribute of the function that
9224 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009225
Georg Brandl3ee81df2008-05-17 18:14:43 +00009226- Issue #1920: "while 0" statements were completely removed by the
9227 compiler, even in the presence of an "else" clause, which is
9228 supposed to be run when the condition is false. Now the compiler
9229 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009230
Guido van Rossumeead05f2008-01-24 18:21:02 +00009231- A few crashers fixed: weakref_in_del.py (issue #1377858);

9238
Georg Brandl3ee81df2008-05-17 18:14:43 +00009239- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009240 several extension methods and modules do not work without unicode
9241 support.
9242
Georg Brandl26543b12008-01-21 18:36:51 +00009243- Issue #1882: when compiling code from a string, encoding cookies in the

9247
Georg Brandl6caad7d2008-01-26 14:19:22 +00009248- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009249 added.
9250
Christian Heimesc94e2b52008-01-14 04:13:37 +00009251- sys.float_info / PyFloat_GetInfo: The floating point information
9252 object was converted from a dict to a specialized structseq object.
9253
Georg Brandl3ee81df2008-05-17 18:14:43 +00009254- Patch #1816: Added sys.flags structseq. It exposes the status of
9255 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009257- Objects/structseq.c: Implemented new structseq representation. The
9258 patch makes structseqs (e.g. the return value of os.stat) more
9259 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009260
Georg Brandl3ee81df2008-05-17 18:14:43 +00009261- Patch #1700288: added a type attribute cache that caches method
9262 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009263
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009264- Bug #1776: __import__() no longer accepts filenames on any platform.

9270 envvar and sys.dont_write_bytecode attribute. All these can be set
9271 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009272
Georg Brandl3ee81df2008-05-17 18:14:43 +00009273- Improve some exception messages when Windows fails to load an
9274 extension module. Now we get for example '%1 is not a valid Win32
9275 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009282- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009283 and INF. float("nan"), float("inf") and float("-inf") now work on
9284 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009285
Georg Brandl3ee81df2008-05-17 18:14:43 +00009286- Compiler now generates simpler and faster code for dictionary
9287 literals. The oparg for BUILD_MAP now indicates an estimated
9288 dictionary size. There is a new opcode, STORE_MAP, for adding
9289 entries to the dictionary.

9332
Georg Brandl21e99f42010-03-07 15:23:59 +00009333- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009334 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9335 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009336
Georg Brandl3ee81df2008-05-17 18:14:43 +00009337- Issue #1686386: Tuple's tp_repr did not take into account the
9338 possibility of having a self-referential tuple, which is possible
9339 from C code. Nor did object's tp_str consider that a type's tp_str
9340 could do something that could lead to an inifinite recursion.
9341 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9342 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009343
Georg Brandl3ee81df2008-05-17 18:14:43 +00009344- Issue #1164: It was possible to trigger deadlock when using the
9345 'print' statement to write to a file since the GIL was not released
9346 as needed. Now PyObject_Print() does the right thing along with
9347 various tp_print implementations of the built-in types and those in
9348 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009349
Georg Brandl3ee81df2008-05-17 18:14:43 +00009350- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00009358 PyObject_Call() never calling back out to Python code to trigger
9359 recursion depth updates/checks. Required the creation of a static
9360 RuntimeError instance in case normalizing an exception put the
9361 recursion check value past its limit. Fixes crashers
9362 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009363

9385 calls.
9386
Collin Winter62903052007-05-18 23:11:24 +00009387- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009388 "except E as target:". This is to provide forwards compatibility
9389 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00009410- Bug #1683368: The object.__init__() and object.__new__() methods are
9411 now stricter in rejecting excess arguments. The only time when
9412 either allows excess arguments is when it is not overridden and the
9413 other one is. For backwards compatibility, when both are
9414 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009415 warning later). Also, type.__init__() insists on the same signature
9416 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009418- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9419 object to complex using its __complex__() method before falling back
9420 to the __float__() method. Therefore, the functions in the cmath
9421 module now can operate on objects that define a __complex__()
9422 method.

9442
Georg Brandl871f1bc2007-03-12 13:17:36 +00009443- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009444 its argument, if it exists. If not, it will work like before. This
9445 allows customizing the output of dir() in the presence of a
9446 __getattr__().

9456 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00009458- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009459 makes the filenames the warning module prints much more sensible
9460 when a PYTHONSTARTUP file is used.

9474 sq_ass_slice instead of the sq_slice slot.
9475
Georg Brandl3ee81df2008-05-17 18:14:43 +00009476- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00009528- Bug #1545497: when given an explicit base, int() did ignore NULs
9529 embedded in the string to convert.
9530
Georg Brandl846f73a2006-10-08 07:11:54 +00009531- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00009561- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
9562 Also make sure that every exception class has __module__ set to

Georg Brandl3ee81df2008-05-17 18:14:43 +00009579 generator expressions (x for x, in ... ) works again. Fixing this
9580 problem required changing the .pyc magic number. This means that
9581 .pyc files generated before 2.5c2 will be regenerated.

10372
Georg Brandl3ee81df2008-05-17 18:14:43 +000010373- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when
10374 the first chunk fed to the decoder started with a BOM, but was
10375 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010376
Georg Brandl3ee81df2008-05-17 18:14:43 +000010377- The implementation of UnicodeError objects has been simplified

10383 obtained from the TLS negotiation itself. Patch contributed by Bill
10384 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010385
Georg Brandl3ee81df2008-05-17 18:14:43 +000010386- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010387 that the SMTP.starttls() caller no longer needs to call ehlo()
10388 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010389 does not claim to support starttls. Adds the
10390 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl309501a2008-01-19 20:22:13 +000010432
Georg Brandl3ee81df2008-05-17 18:14:43 +000010433- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010434 works as expected. ``mmap.find`` also takes an optional ``end``

10460 contents before adding elements from the iterable. This fix brings
10461 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +000010462
Georg Brandl3ee81df2008-05-17 18:14:43 +000010463- Added wide char functions to msvcrt module: getwch, getwche, putwch

10471 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10472 silently miscode subclasses of those types. Now, it raises a
10473 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010474

Georg Brandl3ee81df2008-05-17 18:14:43 +000010489 time so that opening a database previously created with the DB_DUP
10490 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10491 opens. Specifically: dictionary assignment to a DB object will
10492 replace all values for a given key when the database allows
10493 duplicate values. DB users should use DB.put(k, v) when they want
10494 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010495

10501 characters with ASCII value less than 32. Also, it correctly quotes
10502 dots only if they occur on a single line, as opposed to the previous
10503 behavior of quoting dots if they are the second character of any
10504 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010505

Georg Brandl3ee81df2008-05-17 18:14:43 +000010854- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10855 of w# format code incorrectly truncated the length to an int, even
10856 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10857 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010859- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10860 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010866- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10867 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010868
10869- Patch #1733960: Allow T_LONGLONG to accept ints.
10870
10871- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

10876
10877- Fix some leftovers from the conversion from int to Py_ssize_t
10878 (relevant to strings and sequences of more than 2**31 items).
10879
10880- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10881 outside of pystate.c and should not be necessary.

10884 absolute imports. In earlier versions they might have used relative
10885 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010886
Georg Brandl3ee81df2008-05-17 18:14:43 +000010887- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10888 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010889
Georg Brandl3ee81df2008-05-17 18:14:43 +000010890- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010896- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10897 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10898 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10899 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010913- Removed the macfs module. It had been deprecated since Python 2.5.
10914 This lead to the deprecation of macostools.touched() as it relied
10915 solely on macfs and was a no-op under OS X.
