R. David Murray6f0022d2011-01-07 21:57:25 +00001131- email.header.Header was incorrectly encoding folding white space when

1137 time.asctime(), time.ctime() and time.strftime() functions will now format
1138 any year when ``time.accept2dyear`` is False and will accept years >= 1000
1139 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001772- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1773 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001774 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001775 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001776 encoding and to encode command line arguments on this OS.

1779 filenames encoded to the filesystem encoding with the surrogateescape error

1781
Benjamin Peterson230b2062010-10-16 03:45:45 +00001782- Issue #9997: Don't let the name "top" have special significance in scope

2157 Py_Initialize().
2158
Georg Brandl27a28582010-10-10 09:49:21 +00002159- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00002168- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2169 with a non-empty format string. This is an effort to future-proof user
2170 code. If a derived class does not currently implement __format__ but later
2171 adds its own __format__, it would most likely break user code that had
2172 supplied a format string. This will be changed to a DeprecationWaring in
2173 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002175- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly

2177 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

Amaury Forgeot d'Arcfeb73072010-09-12 22:42:57 +00002179- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2180 functions from the libc caused the methods .upper() and lower() to become

2188 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).

Georg Brandl27a28582010-10-10 09:49:21 +00002190- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2192 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2193 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002228- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002229 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002230 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002231 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002256 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002380- Updates to the random module:
2381
Georg Brandl27a28582010-10-10 09:49:21 +00002382 * Document which parts of the module are guaranteed to stay the same across
2383 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002384
Georg Brandl27a28582010-10-10 09:49:21 +00002385 * Update the seed() method to use all of the bits in a string instead of just
2386 the hash value. This makes better use of the seed value and assures the
2387 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002388
Georg Brandl27a28582010-10-10 09:49:21 +00002389 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2390 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2391 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002392
2393 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002412- hashlib has two new constant attributes: algorithms_guaranteed and
2413 algorithms_avaiable that respectively list the names of hash algorithms
2414 guaranteed to exist in all Python implementations and the names of hash
2415 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00002520- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2521 now removed, since their effect was inexistent in 3.x (the default encoding is

2544 return characters from the full Unicode range, even on narrow unicode builds
2545 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2546 in Python is that unicodedata.numeric() now returns the correct value for
2547 large code points, and repr() may consider more characters as printable.

Georg Brandl649971e2010-09-05 17:06:50 +00002584- Issue #9416: Fix some issues with complex formatting where the output with no
2585 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002586
2587 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2588 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Ezio Melotti57221d02010-07-01 07:32:02 +00002927- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00002928 start byte and the continuation byte(s) are now considered invalid, instead of
2929 the number of bytes specified by the start byte. E.g.:
2930 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
2931 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2932 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2933 returned a single u'\ufffd'.

2948 dealing with unary minus applied to a constant. The removed code was mutating
2949 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00002953 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00002954 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00002955
Victor Stinner25e8ec42010-06-25 00:02:38 +00002956- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

2958
Victor Stinner06e49dd2010-06-13 18:21:50 +00002959- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"

2962
Georg Brandl62069d32010-07-31 08:56:11 +00002963- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00002964 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
2965 location of the raised exception.
2966
Victor Stinner313a1202010-06-11 23:56:51 +00002967- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
2968 filenames and enable os.fsencode().
2969
Benjamin Peterson285a6892010-06-22 19:21:52 +00002970- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
2971
Georg Brandl62069d32010-07-31 08:56:11 +00002972- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
2973 interpreter with characters outside the Basic Multilingual Plane (higher than
2974 0x10000).

Georg Brandl62069d32010-07-31 08:56:11 +00002976- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
2977 TypeError instead of giving a DeprecationWarning when a float is parsed using
2978 the 'L' code (for long long). (All other integer codes already raise
2979 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00002980
Victor Stinner600d3be2010-06-10 12:00:55 +00002981- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
2982 enable shortcuts for upper case encoding name. Add also a shortcut for
2983 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
2984
Georg Brandl62069d32010-07-31 08:56:11 +00002985- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
2986 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002987
2988- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00002989 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00002990 like bytearray.
2991
Georg Brandl62069d32010-07-31 08:56:11 +00002992- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00002993 used anymore and it was never documented.
2994
Georg Brandl62069d32010-07-31 08:56:11 +00002995- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00002997- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
2998 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00002999
Georg Brandl62069d32010-07-31 08:56:11 +00003000- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3001 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3002 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3003 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003004
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003005- Issue #8748: Fix two issues with comparisons between complex and integer
3006 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003007 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3008 (2) The comparison raised an OverflowError for large integers, leading to
3009 unpredictable exceptions when combining integers and complex objects in sets
3010 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003011
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003012- Issue #8766: Initialize _warnings module before importing the first module.

3014
Victor Stinner9ca9c252010-05-19 16:53:30 +00003015- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003016 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003017 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003018
Georg Brandl62069d32010-07-31 08:56:11 +00003019- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3020 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003021
Victor Stinnerae6265f2010-05-15 16:27:27 +00003022- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3023 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003024 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003025 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003026
Victor Stinner59e62db2010-05-15 13:14:32 +00003027- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003028 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003029
Victor Stinnerb744ba12010-05-15 12:27:16 +00003030- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003031 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003032 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3033
Victor Stinner0964ee12010-04-30 16:48:45 +00003034- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003035 PyUnicode_FromString() to support surrogates in the filename and use the right
3036 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00003038- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3039
Georg Brandl62069d32010-07-31 08:56:11 +00003040- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.

Benjamin Petersonfb886362010-04-24 18:21:17 +00003042- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3043 arguments.
3044
Victor Stinner14284c22010-04-23 12:02:30 +00003045- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003046 indirectly Python signal handlers anymore because mywrite() ignores exceptions

Mark Dickinsone6fc7402010-08-06 18:55:26 +00003316- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3317 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3318 "step = -step" when reversing a slice.

3340 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3341 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003342 to match the behaviour of the other integer format codes.

3448 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003449 applications that use a lot of regular expressions and limits the impact of
3450 the performance hit anytime the cache is exceeded.

3464 defined in datetime with fast C impementation. Python implementation is based
3465 on the original python prototype for the datetime module by Tim Peters with

Georg Brandl62069d32010-07-31 08:56:11 +00003864- Issue #2531: Comparison operations between floats and Decimal instances now
3865 return a result based on the numeric values of the operands; previously they
3866 returned an arbitrary result based on the relative ordering of id(float) and
3867 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3868 comparisons.

Barry Warsawd5f9bf52010-03-31 21:36:22 +00003872- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003873 argument `-` which tells it to read files to compile from stdin. Each line is
3874 read on demand and the named file is compiled immediately. (Original patch by

3882 Fractions instance now raise TypeError instead of returning True/False. This
3883 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3884 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003927- The internals of the subprocess module on POSIX systems have been replaced by
3928 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3929 safely without the possibility of deadlock in multithreaded applications.

Georg Brandl62069d32010-07-31 08:56:11 +00003931- subprocess.Popen now has restore_signals and start_new_session features. The
3932 default of restore_signals=True is a new behavior compared to earlier Python
3933 versions. This means that signals such as SIGPIPE are not ignored by default
3934 in subprocesses launched by Python (Issue #1652).

Georg Brandl62069d32010-07-31 08:56:11 +00004020- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
4021 position when calling `truncate()`. It would previously change the file
4022 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004023 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00004025- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004026 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4027 archive. The new implementation is significantly faster and can be wrapped in
4028 a :class:`io.BufferedReader` object for more speedups. It also solves an
4029 issue where interleaved calls to `read()` and `readline()` give wrong results.

Georg Brandl62069d32010-07-31 08:56:11 +00004428 compared to other unix systems. In particular, os.getgroups() does not reflect

4996
Antoine Pitrou61f77b52009-05-24 15:46:13 +00004997- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
4998 than an int, which makes some operations possible under 64-bit Linux (e.g.
4999 DN_MULTISHOT with F_NOTIFY).
5000

5022
Antoine Pitroue4501852009-05-14 18:55:55 +00005023- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5024 library. This means, for example, that opening an UTF-16 text file in
5025 append mode doesn't add a BOM at the end of the file if the file isn't
5026 empty.
5027
R. David Murray74b89242009-05-13 17:33:03 +00005028- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

5031
Georg Brandl5f90d792010-08-01 22:31:05 +00005032- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005033 now it does. This also means getfp method now returns the real fp.

5076Core and Builtins
5077-----------------
5078
Mark Dickinson865e01a2009-05-07 16:37:01 +00005079- Issue #5914: Add new C API function PyOS_string_to_double, and
5080 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5081
Eric Smith741191f2009-05-06 13:08:15 +00005082- Issue #3382: float.__format__, complex.__format__, and %-formatting
5083 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5084 affects nan -> NAN and inf -> INF.
5085
Mark Hammond5a607a32009-05-06 08:04:54 +00005086- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5087 in all operations, including splitdrive, split, etc. splitunc() now issues
5088 a PendingDeprecation warning.
5089
Eric Smith63376222009-05-05 14:04:18 +00005090- Issue #5920: For float.__format__, change the behavior with the
5091 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5092 to be like 'g' but with at least one decimal point and with a
5093 default precision of 12. Previously, the behavior the same but with
5094 a default precision of 6. This more closely matches str(), and
5095 reduces surprises when adding alignment flags to the empty
5096 presentation type. This also affects the new complex.__format__ in
5097 the same way.
5098
Martin v. Löwis011e8422009-05-05 04:43:17 +00005099- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5100
R. David Murrayb18500d2009-05-04 22:59:07 +00005101- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5102 shadowed by classtype's, even if it was None. property now
5103 inserts the __doc__ into the subclass instance __dict__.
5104
Antoine Pitrou244651a2009-05-04 18:56:13 +00005105- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5106 sequences. Patch by Nick Barnes and Victor Stinner.
5107
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005108- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005109
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005110- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5111 received a new method, detach(). detach() disconnects the underlying stream
5112 from the buffer or text IO and returns it.
5113
Mark Dickinson33841c32009-05-01 15:37:04 +00005114- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5115 floats with absolute value over 1e50. Also remove length
5116 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5117 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005118
Eric Smith741191f2009-05-06 13:08:15 +00005119- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005120 format(complex(1, 2./3), '.5') now produces a sensible result.
5121
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005122- Issue #5864: Fix empty format code formatting for floats so that it
5123 never gives more than the requested number of significant digits.
5124
Eric Smith6dc46f52009-04-27 20:39:49 +00005125- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5126 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5127
Eric Smithcc32a112009-04-26 21:35:14 +00005128- Issue #5835: Deprecate PyOS_ascii_formatd.
5129
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005130- Issue #4971: Fix titlecase for characters that are their own
5131 titlecase, but not their own uppercase.
5132
Benjamin Peterson193152c2009-04-25 01:08:45 +00005133- Issue #5283: Setting __class__ in __del__ caused a segfault.
5134
Mark Dickinsonad476da2009-04-23 19:14:16 +00005135- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5136 z involves nans, infs or negative zeros.
5137
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005138- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005139
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005140- Issue #1869 (and many duplicates): make round(x, n) correctly
5141 rounded for a float x, by using the decimal <-> binary conversions
5142 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5143 consistently agrees with format(x, '.2f').
5144
Benjamin Petersonae937c02009-04-18 20:54:08 +00005145- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5146 some builtin types.
5147
Eric Smith0923d1d2009-04-16 20:16:10 +00005148- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5149
Eric Smith35e84722009-04-16 20:21:28 +00005150- Issue #5515: str.format() type 'n' combined with commas and leading
5151 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005152
5153- Implement PEP 378, Format Specifier for Thousands Separator, for
5154 floats.
5155
Mark Dickinson3370cce2009-04-17 22:40:53 +00005156- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005157 1e11, not 1e12. This avoids printing 13 significant digits in
5158 situations where only 12 of them are correct. Example problem
5159 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5160 long time.)
5161
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005162- Issue #1580: On most platforms, use a 'short' float repr: for a
5163 finite float x, repr(x) now outputs a string based on the shortest
5164 sequence of decimal digits that rounds to x. Previous behaviour was
5165 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005166 Another minor difference is that the new repr switches to
5167 exponential notation at 1e16 instead of the previous 1e17; this
5168 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005169
5170 There's a new sys attribute sys.float_repr_style, which takes
5171 the value 'short' to indicate that we're using short float repr,
5172 and 'legacy' if the short float repr isn't available for one
5173 reason or another.
5174
5175 The float repr change involves incorporating David Gay's 'perfect
5176 rounding' code into the Python core (it's in Python/dtoa.c). As a
5177 secondary consequence, all string-to-float and float-to-string
5178 conversions (including all float formatting operations) will be
5179 correctly rounded on these platforms.
5180
Georg Brandl5f90d792010-08-01 22:31:05 +00005181 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005182 this change does not apply.
5183
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005184- Issue #5759: float() didn't call __float__ on str subclasses.
5185
Georg Brandlabc38772009-04-12 15:51:51 +00005186- The string.maketrans() function is deprecated; there is a new static method
5187 maketrans() on the bytes and bytearray classes. This removes confusion about
5188 the types string.maketrans() is supposed to work with, and mirrors the
5189 methods available on the str class.
5190
R. David Murraydc6da8a2009-04-09 22:16:43 +00005191- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5192 its clarity and its speed.
5193
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005194- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005195 to avoid compiler warnings.
5196
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005197- Issue #3739: The unicode-internal encoder now reports the number of characters
5198 consumed like any other encoder (instead of the number of bytes).

5279 results in a handle_expt_event call, not handle_read_event, and POLLERR
5280 and POLLNVAL now call handle_close, not handle_expt_event. Also,
5281 dispatcher now has an 'ignore_log_types' attribute for suppressing
5282 log messages, which is set to 'warning' by default.
5283
Matthias Klosea3d29e82009-04-07 13:13:10 +00005284- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

5358 untrackable objects are not tracked by the garbage collector. This can
5359 reduce the size of collections and therefore the garbage collection overhead
5360 on long-running programs, depending on their particular use of datatypes.

5376
Eric Smith8ec90442009-03-14 12:29:34 +00005377- Issue #5237: Allow auto-numbered fields in str.format(). For

5431 forever on incomplete input. That caused tarfile.open() to hang when used
5432 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5433 partial bzip2 compressed data.
5434
Mark Dickinson79f52032009-03-17 23:12:51 +00005435- Issue #2110: Add support for thousands separator and 'n' type

Raymond Hettinger35631532009-01-09 03:58:09 +00005554- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5555 instead of ints (reducing its size from 4 to 8 times thereby reducing
5556 Python's overall memory).
5557
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005558- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5559 an existing .py counterpart, override the co_filename attributes of all
5560 code objects if the original filename is obsolete (which can happen if the
5561 file has been renamed, moved, or if it is accessed through different paths).
5562 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5563

5608
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005609- Issue #4445: Replace "sizeof(PyBytesObject)" with
5610 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5611 bytes instances. On a typical machine this saves 3 bytes of memory
5612 (on average) per allocation of a bytes instance.
5613
Christian Heimesa872de52008-12-05 08:26:55 +00005614- Issue #4533: File read operation was dreadfully slow due to a slowly

5616 Python 2.x.
5617
Antoine Pitrou5504e892008-12-06 21:27:53 +00005618- Issue #4509: Various issues surrounding resize of bytearray objects to

5620
Georg Brandlf9734072008-12-07 15:30:06 +00005621- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5622 method on file objects with closefd=False. The file descriptor is still
5623 kept open but the file object behaves like a closed file. The ``FileIO``
5624 object also got a new readonly attribute ``closefd``.

5634 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5635 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5636 of using the replace error handler in PyUnicode_DecodeUTF8().

5955
Antoine Pitrou08838b62009-01-21 00:55:13 +00005956- Issue #5008: When a file is opened in append mode with the new IO library,
5957 do an explicit seek to the end of file (so that e.g. tell() returns the
5958 file size rather than 0). This is consistent with the behaviour of the

5989 appropriately when it is being used via socket.makefile() objects
5990 rather than delaying the close by waiting for garbage collection to do it.
5991
