795 * Try to avoid building Python or extension modules with problematic
796 llvm-gcc compiler.
797 * Since Xcode 4 removes ppc support, extension module builds now
798 check for ppc compiler support and automatically remove ppc and
799 ppc64 archs when not available.
800 * Since Xcode 4 no longer install SDKs in default locations,
801 extension module builds now revert to using installed headers
802 and libs if the SDK used to build the interpreter is not
803 available.
804 * Update ./configure to use better defaults for universal builds;
805 in particular, --enable-universalsdk=yes uses the Xcode default
806 SDK and --with-universal-archs now defaults to "intel" if ppc
807 not available.

2165 Distutils-based packages with C extension modules may fail because
2166 Apple has removed gcc-4.2, the version used to build python.org
2167 64-bit/32-bit Pythons. If the user does not explicitly override
2168 the default C compiler by setting the CC environment variable,
2169 Distutils will now attempt to compile extension modules with clang
2170 if gcc-4.2 is required but not found. Also as a convenience, if
2171 the user does explicitly set CC, substitute its value as the default
2172 compiler in the Distutils LDSHARED configuration variable for OS X.
2173 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2174 SDK, neither of which are available in Xcode 4. This change does not
2175 attempt to override settings to support their use with Xcode 4.)

2754 Condition, etc.) used to be factory functions returning instances of hidden
2755 classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this

2901
Ned Deily657b2de2011-06-28 19:51:30 -07002902- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2903 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2904 interpreter process. This could cause failures in non-Distutils subprocesses
2905 and was unreliable since tests or user programs could modify the interpreter
2906 environment after Distutils set it. Instead, have Distutils set the the
2907 deployment target only in the environment of each build subprocess. It is
2908 still possible to globally override the default by setting
2909 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2910 greater or equal to the default value, the value with which the interpreter

4090 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
4091 for all file entries in the ZIP file.

4101- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
4102 encoding. This is the preferred encoding of PEP 3333 and the base encoding
4103 of HTTP 1.1.
Steven Bethardb0270112011-01-24 21:02:50 +00004104
4105- To match the behaviour of HTTP server, the HTTP client library now also
Georg Brandl0c5036f2011-01-16 08:44:50 +00004106 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
Georg Brandld2f38572011-01-30 08:37:19 +00004107 that for incoming headers which makes this behaviour now consistent in
4108 both incoming and outgoing direction.

R. David Murray5b2d9dd2011-01-09 02:35:24 +00004204- Issue #5871: email.header.Header.encode now raises an error if any
Georg Brandl255abdd2011-01-16 14:17:26 +00004205 continuation line in the formatted value has no leading white space and looks
4206 like a header. Since Generator uses Header to format all headers, this check
4207 is made for all headers in any serialized message at serialization time. This
4208 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +00004209

Éric Araujof0ab5d62011-05-29 03:43:59 +02004217 non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
Georg Brandl255abdd2011-01-16 14:17:26 +00004218 presentation, instead of replacing them with ?s.
R. David Murray92532142011-01-07 23:25:30 +00004219
Éric Araujof0ab5d62011-05-29 03:43:59 +02004220- email.header.Header was incorrectly encoding folding whitespace when
Georg Brandl255abdd2011-01-16 14:17:26 +00004221 rfc2047-encoding header values with embedded newlines, leaving them without
4222 folding whitespace. It now uses the continuation_ws, as it does for
4223 continuation lines that it creates itself.

Victor Stinner3ec899f2011-01-08 16:37:47 +00004225- Issue #1777412, #10827: Changed the rules for 2-digit years. The
4226 time.asctime(), time.ctime() and time.strftime() functions will now format
4227 any year when ``time.accept2dyear`` is False and will accept years >= 1000
4228 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
4229 supported by the OS. With Visual Studio or on Solaris, the year is limited to
4230 the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.

Georg Brandl27a28582010-10-10 09:49:21 +00005220- ast.literal_eval() can now handle negative numbers. It is also a little more
5221 liberal in what it accepts without compromising the safety of the evaluation.
5222 For example, 3j+4 and 3+4+5 are both accepted.

5251 Py_Initialize().
5252
Georg Brandl27a28582010-10-10 09:49:21 +00005253- All SyntaxErrors now have a column offset and therefore a caret when the error
5254 is printed.

Brett Cannonbc2eff32010-09-19 21:39:02 +00005256- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the

5258
Nick Coghlan37ee8502010-12-03 14:26:13 +00005259- Issue #9213: The range type_items now provides index() and count() methods, to

Georg Brandl27a28582010-10-10 09:49:21 +00005262- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5263 with a non-empty format string. This is an effort to future-proof user
5264 code. If a derived class does not currently implement __format__ but later
5265 adds its own __format__, it would most likely break user code that had
5266 supplied a format string. This will be changed to a DeprecationWaring in
5267 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00005269- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
5270 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
5271 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
5272
Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00005273- Issue #9210: Configure option --with-wctype-functions was removed. Using the
5274 functions from the libc caused the methods .upper() and lower() to become
5275 locale aware and created subtly wrong results.
5276
Georg Brandl27a28582010-10-10 09:49:21 +00005277- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
5278 non-ASCII byte in the format string.
Victor Stinner1205f272010-09-11 00:54:47 +00005279
Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00005280- Issue #4617: Previously it was illegal to delete a name from the local
5281 namespace if it occurs as a free variable in a nested block. This limitation
5282 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
5283
Georg Brandl27a28582010-10-10 09:49:21 +00005284- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
5285 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
5286 Also, the "backslashreplace" error handler now joins surrogate pairs into a
5287 single character on UCS-2 builds.

Antoine Pitrou6e6cc832010-09-09 12:59:39 +00005289- Issue #9757: memoryview objects get a release() method to release the
5290 underlying buffer (previously this was only done when deallocating the
5291 memoryview), and gain support for the context management protocol.
5292
Antoine Pitrou079ce542010-09-08 12:37:10 +00005293- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00005322- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005323 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00005324 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00005325 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00005399 non-blocking mode: they return None when an operation would block (instead of

Raymond Hettingerfa11db02010-09-12 04:12:42 +00005432- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00005433 it possible for the user to create self-referencing ordered dictionaries which
5434 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00005435 approach of using weakref proxies so that reference cycles never get created
5436 in the first place.

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00005461- Issue #6394: os.getppid() is now supported on Windows. Note that it will
5462 still return the id of the parent process after it has exited. This process
5463 id may even have been reused by another unrelated process.
5464
Georg Brandl27a28582010-10-10 09:49:21 +00005465- Issue #9792: In case of connection failure, socket.create_connection() would

Georg Brandl27a28582010-10-10 09:49:21 +00005483 * Improved the random()-->integer algorithm used in choice(), shuffle(),
5484 sample(), randrange(), and randint(). Formerly, it used int(n*random())
5485 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00005486
5487 * Improved documentation of arguments to randrange(). Issue #9379.

5508 guaranteed to exist in all Python implementations and the names of hash
5509 algorithms available in the current process.

6027 returned a single u'\ufffd'.

Georg Brandl62069d32010-07-31 08:56:11 +00006070- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
6071 TypeError instead of giving a DeprecationWarning when a float is parsed using
6072 the 'L' code (for long long). (All other integer codes already raise
6073 TypeError in this case.)

Georg Brandl62069d32010-07-31 08:56:11 +00006083 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00006084 like bytearray.

Mark Dickinsoncc6a9822010-05-21 14:55:26 +00006099- Issue #8748: Fix two issues with comparisons between complex and integer
6100 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00006101 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
6102 (2) The comparison raised an OverflowError for large integers, leading to
6103 unpredictable exceptions when combining integers and complex objects in sets
6104 or dicts.

6127
Victor Stinner0964ee12010-04-30 16:48:45 +00006128- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

Georg Brandl62069d32010-07-31 08:56:11 +00006292- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
6293 range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
6294 long but the length of the range did not. Also fix several cases where
6295 reversed(range(a, b, c)) gave wrong results, and fix a refleak for
6296 reversed(range(a, b, c)) with large arguments.

Alexander Belopolskyf0f45142010-08-11 17:31:17 +00006406- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
6407 variable argument list. `Py_VA_COPY` is equivalent to C99
6408 `va_copy`, but available on all python platforms.
6409
Mark Dickinsone6fc7402010-08-06 18:55:26 +00006410- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
6411 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
6412 "step = -step" when reversing a slice.

Antoine Pitrou8689a102010-04-01 16:53:15 +00006422- Issue #8276: PyEval_CallObject() is now only available in macro form. The
Georg Brandl62069d32010-07-31 08:56:11 +00006423 function declaration, which was kept for backwards compatibility reasons, is
6424 now removed (the macro was introduced in 1997!).

6434 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
6435 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00006436 to match the behaviour of the other integer format codes.
6437

6447 PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
6448 accessing the d_type and d_name members of structures using PyDescr_COMMON.

Georg Brandl62069d32010-07-31 08:56:11 +00006463- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6464 allocator will be automatically disabled when running under Valgrind. This
6465 gives improved memory leak detection when running under Valgrind, while taking
6466 advantage of pymalloc at other times.

Georg Brandl62069d32010-07-31 08:56:11 +00006539- The default size of the re module's compiled regular expression cache has been
6540 increased from 100 to 500 and the cache replacement policy has changed from
Antoine Pitrou3060c452010-08-13 16:27:38 +00006541 simply clearing the entire cache on overflow to forgetting the least recently
6542 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00006543 applications that use a lot of regular expressions and limits the impact of
6544 the performance hit anytime the cache is exceeded.

6557 module is renamed to `_datetime` and if available, overrides all classes
6558 defined in datetime with fast C impementation. Python implementation is based
6559 on the original python prototype for the datetime module by Tim Peters with
6560 minor modifications by the PyPy project. The test suite now tests `datetime`
6561 module with and without `_datetime` acceleration using the same test cases.

6789
Victor Stinnerd17f2192010-08-15 09:56:07 +00006790- Issue #8390: tarfile uses surrogateescape as the default error handler
Georg Brandl62069d32010-07-31 08:56:11 +00006791 (instead of replace in read mode or strict in write mode).

Georg Brandl62069d32010-07-31 08:56:11 +00006798- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
6799 operation raises multiple signals and more than one of those signals is
6800 trapped, the specification determines the order in which the signals should be
6801 handled. In many cases this order wasn't being followed, leading to the wrong
6802 Python exception being raised.
Mark Dickinsonc69160e2010-05-04 14:35:33 +00006803
Georg Brandl88b95f92012-05-06 11:24:06 +02006804- Issue #7865: The close() method of ``io`` objects should not swallow
Georg Brandl62069d32010-07-31 08:56:11 +00006805 exceptions raised by the implicit flush(). Also qensure that calling close()

6837 the method could block indefinitely if called just before the event loop
6838 started running. This also fixes the occasional freezes witnessed in

Georg Brandl62069d32010-07-31 08:56:11 +00006841- Issue #8524: When creating an SSL socket, the timeout value of the original
6842 socket wasn't retained (instead, a socket with a positive timeout would be
6843 turned into a non-blocking SSL socket).
Antoine Pitrou40f08742010-04-24 22:04:40 +00006844
Antoine Pitroud3f8ab82010-04-24 21:26:44 +00006845- Issue #5103: SSL handshake would ignore the socket timeout and block
6846 indefinitely if the other end didn't respond.
6847
Georg Brandl62069d32010-07-31 08:56:11 +00006848- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandl62069d32010-07-31 08:56:11 +00006860- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
6861 string "python" as the *ident*. openlog() arguments are all optional and
6862 keywords.
Sean Reifscheider13daf122010-04-23 09:29:52 +00006863
Georg Brandl62069d32010-07-31 08:56:11 +00006864- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
6865 non-infinite timeout. Also make that method friendlier with applications
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +00006866 wanting to continue using the socket in clear-text mode, by disabling
6867 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

Antoine Pitrou7c3e5772010-04-14 15:44:10 +00006917 module now takes an optional timeout argument in seconds. Timeout support
Georg Brandl62069d32010-07-31 08:56:11 +00006918 relies on the system threading library, so as to avoid a semi-busy wait loop.
Antoine Pitrou7c3e5772010-04-14 15:44:10 +00006919

R. David Murrayb2416e52010-04-12 16:58:02 +00006924- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandl62069d32010-07-31 08:56:11 +00006925 filename and date, conforming to the 'standards' they were originally designed

Georg Brandl62069d32010-07-31 08:56:11 +00006953- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6954 InvalidOperation instead of returning False. (Comparisons involving a quiet
6955 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6956 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00006957
Georg Brandl62069d32010-07-31 08:56:11 +00006958- Issue #2531: Comparison operations between floats and Decimal instances now
6959 return a result based on the numeric values of the operands; previously they
6960 returned an arbitrary result based on the relative ordering of id(float) and
6961 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
6962 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00006963
Raymond Hettinger9c01e442010-04-03 10:32:58 +00006964- Added a subtract() method to collections.Counter().

Georg Brandl62069d32010-07-31 08:56:11 +00006967 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandl62069d32010-07-31 08:56:11 +00006975- Comparisons using one of <, <=, >, >= between a complex instance and a
6976 Fractions instance now raise TypeError instead of returning True/False. This
6977 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6978 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00007025- subprocess.Popen now has restore_signals and start_new_session features. The
7026 default of restore_signals=True is a new behavior compared to earlier Python
7027 versions. This means that signals such as SIGPIPE are not ignored by default
7028 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00007114- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
7115 position when calling `truncate()`. It would previously change the file
7116 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00007117 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
7118
Antoine Pitroua32f9a22010-01-27 21:18:57 +00007119- Issue #7610: Reworked implementation of the internal
Georg Brandl88b95f92012-05-06 11:24:06 +02007120 ``zipfile.ZipExtFile`` class used to represent files stored inside an
Georg Brandl62069d32010-07-31 08:56:11 +00007121 archive. The new implementation is significantly faster and can be wrapped in
Georg Brandl88b95f92012-05-06 11:24:06 +02007122 a ``io.BufferedReader`` object for more speedups. It also solves an
Georg Brandl62069d32010-07-31 08:56:11 +00007123 issue where interleaved calls to `read()` and `readline()` give wrong results.

Brett Cannon69194272009-07-20 04:23:48 +00007459- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
Georg Brandl62069d32010-07-31 08:56:11 +00007460 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
7461 PyPycLoader inherit from this class and provide implementations in relation to
7462 other methods required by the ABCs.
Brett Cannon69194272009-07-20 04:23:48 +00007463
Brett Cannon64ef00f2009-07-20 03:19:18 +00007464- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
7465 the documentation said it did even though the code in PyLoader relied on the
7466 abstract method required by ResourceLoader.
7467
Georg Brandl62069d32010-07-31 08:56:11 +00007468- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00007521- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00007522 compared to other unix systems. In particular, os.getgroups() does not reflect
7523 any changes made using os.setgroups() but basicly always returns the same
7524 information as the id command. os.getgroups() can now return more than 16
7525 groups on MacOSX.

Georg Brandl62069d32010-07-31 08:56:11 +00007550- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
7551 Prior to this change, timezone adjustment in utctimetuple() could produce
7552 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
7553 cases.

Georg Brandl62069d32010-07-31 08:56:11 +00007555- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
7556 directive. When the ``%z`` directive is present in the format string, an
7557 aware ``datetime`` object is returned with ``tzinfo`` bound to a
7558 ``datetime.timezone`` instance constructed from the parsed offset. If both
7559 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
7560 name, but ``%Z`` data without ``%z`` is discarded.

Alexander Belopolsky4e749a12010-06-14 14:15:50 +00007562- Issue #5094: The ``datetime`` module now has a simple concrete class
Georg Brandl62069d32010-07-31 08:56:11 +00007563 implementing ``datetime.tzinfo`` interface. Instances of the new class,
7564 ``datetime.timezone``, return fixed name and UTC offset from their
7565 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
7566 returns ``None``. A class attribute, ``utc`` contains an instance
7567 representing the UTC timezone. Original patch by Rafe Kaplan.

7584 with an improved 'binary-split' algorithm that uses fewer multiplications and
7585 allows many of the multiplications to be performed using plain C integer
7586 arithmetic instead of PyLong arithmetic. Also uses a lookup table for small

7593 calculating with integer arithmetic instead of float arithmetic internally):
Georg Brandl62069d32010-07-31 08:56:11 +00007594 the result is now always correctly rounded, and is equivalent to ``td /
7595 timedelta(seconds=1)``.

7604 integer format code, struct.pack first attempts to convert the non-integer
7605 using its __index__ method. If that method is non-existent or raises
7606 TypeError it goes on to try the __int__ method, as described below.

8187 default precision of 12. Previously, the behavior the same but with
8188 a default precision of 6. This more closely matches str(), and
8189 reduces surprises when adding alignment flags to the empty
8190 presentation type. This also affects the new complex.__format__ in
8191 the same way.

8206 from the buffer or text IO and returns it.
8207
Mark Dickinson33841c32009-05-01 15:37:04 +00008208- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
8209 floats with absolute value over 1e50. Also remove length
8210 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
8211 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00008213- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00008214 format(complex(1, 2./3), '.5') now produces a sensible result.
8215
Mark Dickinsond3ca5572009-04-29 18:47:07 +00008216- Issue #5864: Fix empty format code formatting for floats so that it

8218
Eric Smith6dc46f52009-04-27 20:39:49 +00008219- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

8231
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00008232- Issue #3166: Make int -> float conversions correctly rounded.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00008234- Issue #1869 (and many duplicates): make round(x, n) correctly
8235 rounded for a float x, by using the decimal <-> binary conversions
8236 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
8237 consistently agrees with format(x, '.2f').
8238
Benjamin Petersonae937c02009-04-18 20:54:08 +00008239- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +00008242- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
8243
Eric Smith35e84722009-04-16 20:21:28 +00008244- Issue #5515: str.format() type 'n' combined with commas and leading
8245 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00008246
8247- Implement PEP 378, Format Specifier for Thousands Separator, for
8248 floats.
8249
Mark Dickinson3370cce2009-04-17 22:40:53 +00008250- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008251 1e11, not 1e12. This avoids printing 13 significant digits in
8252 situations where only 12 of them are correct. Example problem
8253 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
8254 long time.)
8255
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008256- Issue #1580: On most platforms, use a 'short' float repr: for a
8257 finite float x, repr(x) now outputs a string based on the shortest
8258 sequence of decimal digits that rounds to x. Previous behaviour was
8259 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00008260 Another minor difference is that the new repr switches to
8261 exponential notation at 1e16 instead of the previous 1e17; this
8262 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008263
8264 There's a new sys attribute sys.float_repr_style, which takes
8265 the value 'short' to indicate that we're using short float repr,
8266 and 'legacy' if the short float repr isn't available for one
8267 reason or another.
8268
8269 The float repr change involves incorporating David Gay's 'perfect
8270 rounding' code into the Python core (it's in Python/dtoa.c). As a
8271 secondary consequence, all string-to-float and float-to-string
8272 conversions (including all float formatting operations) will be
8273 correctly rounded on these platforms.
8274
Georg Brandl5f90d792010-08-01 22:31:05 +00008275 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00008276 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00008278- Issue #5759: float() didn't call __float__ on str subclasses.
8279
Georg Brandlabc38772009-04-12 15:51:51 +00008280- The string.maketrans() function is deprecated; there is a new static method
8281 maketrans() on the bytes and bytearray classes. This removes confusion about
8282 the types string.maketrans() is supposed to work with, and mirrors the
8283 methods available on the str class.

8452 untrackable objects are not tracked by the garbage collector. This can
8453 reduce the size of collections and therefore the garbage collection overhead
8454 on long-running programs, depending on their particular use of datatypes.

8575 rotating the object pointer by 4 bits to the right.
8576
Mark Dickinson87ec0852009-02-09 17:15:59 +00008577- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
8578 it now forces its argument to double before testing for infinity.
8579
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00008580- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
8581 returns a non-number type.
8582
Benjamin Peterson87618552009-02-08 15:00:52 +00008583- Issue #5182: Removed memoryview.__str__.
8584
Mark Dickinsonc008a172009-02-01 13:59:22 +00008585- Issue #1717: Removed builtin cmp() function, dropped tp_compare
8586 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00008587 the type definition cmpfunc. The tp_compare slot has been renamed
8588 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00008589
Georg Brandl1cdd83c2009-04-05 20:24:29 +00008590- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00008591 were suppressing all exceptions. These include list() and bytearray().
8592
Mark Dickinson1124e712009-01-28 21:25:58 +00008593- Issue #4707: round(x, n) now returns an integer if x is an integer.
8594 Previously it returned a float.
8595
Antoine Pitroub52ec782009-01-25 16:34:23 +00008596- Issue #4753: By enabling a configure option named '--with-computed-gotos'
8597 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
8598 evaluation loop is compiled with a new dispatch mechanism which gives
8599 speedups of up to 20%, depending on the system, on various benchmarks.
8600
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00008601- Issue #4874: Most builtin decoders now reject unicode input.

8609 optional module state data.
8610
Mark Dickinson8055afd2009-01-17 10:04:45 +00008611- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008612 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00008613
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00008614- Issue #4935: The overflow checking code in the expandtabs() method common
8615 to str, bytes and bytearray could be optimized away by the compiler, letting
8616 the interpreter segfault instead of raising an error.
8617
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00008618- Issue #3720: Fix a crash when an iterator modifies its class and removes its
8619 __next__ method.
8620
Mark Dickinsone5e298f2009-01-12 20:49:19 +00008621- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
8622 function no longer attempt to call the __long__ slot to convert an object
8623 to an integer. Only the __int__ and __trunc__ slots are examined.
8624
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00008625- Issue #4893: Use NT threading on CE.
8626
Martin v. Löwisec59d042009-01-12 07:59:10 +00008627- Issue #4915: Port sysmodule to Windows CE.
8628
Antoine Pitrouab868312009-01-10 15:40:25 +00008629- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
8630 common cases are optimized thanks to a dedicated fast path and a moderate
8631 amount of loop unrolling.
8632
Antoine Pitrou14b78f52009-01-09 22:27:08 +00008633- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
8634 collecting the oldest generation) so that allocating lots of objects without
8635 destroying them does not show quadratic performance. Based on a proposal by
8636 Martin von Löwis at
8637 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
8638
Vinay Sajip6268cbc2009-01-21 00:19:28 +00008639- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00008640 having been closed (for instance, a read() call could return some
8641 previously buffered data). Patch by Dmitry Vasiliev.
8642
Antoine Pitrou05608432009-01-09 18:53:14 +00008643- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
8644 flag to work properly. Furthermore, when specifying -u, the text stdout
8645 and stderr streams have line-by-line buffering enabled (the default being
8646 to buffer arbitrary chunks of data).
8647
Raymond Hettinger35631532009-01-09 03:58:09 +00008648- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
8649 instead of ints (reducing its size from 4 to 8 times thereby reducing
8650 Python's overall memory).
8651
Antoine Pitroud35cbf62009-01-06 19:02:24 +00008652- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
8653 an existing .py counterpart, override the co_filename attributes of all
8654 code objects if the original filename is obsolete (which can happen if the
8655 file has been renamed, moved, or if it is accessed through different paths).
8656 Patch by Ziga Seilnacht and Jean-Paul Calderone.
8657
Antoine Pitrouc3b39242009-01-03 16:59:18 +00008658- Issue #4580: Fix slicing of memoryviews when the item size is greater than
8659 one byte. Also fixes the meaning of len() so that it returns the number of
8660 items, rather than the size in bytes.
8661
Martin v. Löwis5c88d812009-01-02 20:47:48 +00008662- Issue #4075: Use OutputDebugStringW in Py_FatalError.
8663
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00008664- Issue #4747: When the terminal does not use utf-8, executing a script with
8665 non-ascii characters in its name could fail with a "SyntaxError: None" error.
8666
Georg Brandl65ce6ad2010-09-05 17:32:31 +00008667- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
8668 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00008669
Antoine Pitrou7ddda782009-01-01 15:35:33 +00008670- Issue #3680: Reference cycles created through a dict, set or deque iterator
8671 did not get collected.
8672
Nick Coghlanf1f2f682008-12-30 07:29:12 +00008673- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
8674 where the tp_hash and tp_dict slots are both NULL.
8675
Georg Brandlccc47b62008-12-28 11:44:14 +00008676- Issue #4759: None is now allowed as the first argument of
8677 bytearray.translate(). It was always allowed for bytes.translate().
8678
Skip Montanaro80072cb2008-12-23 03:51:14 +00008679- Added test case to ensure attempts to read from a file opened for writing
8680 fail.
8681
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00008682- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00008684- Issue #2183: Simplify and optimize bytecode for list, dict and set
8685 comprehensions. Original patch for list comprehensions by Neal Norwitz.
8686
Antoine Pitrou621601a2008-12-17 23:18:19 +00008687- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
8688 print elapsed times, not only when some objects are uncollectable /
8689 unreachable. Original patch by Neil Schemenauer.
8690
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00008691- Issue #3439: Add a bit_length method to int.
8692
Mark Dickinsonda2706b2008-12-11 18:03:03 +00008693- Issue #2173: When getting device encoding, check that return value of
8694 nl_langinfo is not the empty string. This was causing silent build
8695 failures on OS X.
8696
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00008697- Issue #4597: Fixed several opcodes that weren't always propagating
8698 exceptions.
8699
8700- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00008701 context manager returns a value that cannot be converted to a bool.
8702
Mark Dickinsonfd24b322008-12-06 15:33:31 +00008703- Issue #4445: Replace "sizeof(PyBytesObject)" with
8704 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
8705 bytes instances. On a typical machine this saves 3 bytes of memory
8706 (on average) per allocation of a bytes instance.
8707
Christian Heimesa872de52008-12-05 08:26:55 +00008708- Issue #4533: File read operation was dreadfully slow due to a slowly
8709 growing read buffer. Fixed by using the same growth rate algorithm as
8710 Python 2.x.
8711
Antoine Pitrou5504e892008-12-06 21:27:53 +00008712- Issue #4509: Various issues surrounding resize of bytearray objects to
8713 which there are buffer exports (e.g. memoryview instances).
8714
Georg Brandlf9734072008-12-07 15:30:06 +00008715- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
8716 method on file objects with closefd=False. The file descriptor is still
8717 kept open but the file object behaves like a closed file. The ``FileIO``
8718 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00008719
Antoine Pitroubc420402008-12-07 20:14:49 +00008720- Issue #4569: Interpreter crash when mutating a memoryview with an item size

8726
Walter Dörwaldc1651a02009-05-03 22:55:55 +00008727- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
8728 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
8729 step. This avoids problems with counting UTF-8 bytes that ignores the effect
8730 of using the replace error handler in PyUnicode_DecodeUTF8().
