R. David Murrayb7deff12011-01-30 06:21:28 +0000604- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
605 files in binary mode, using the email package's binary support to parse
606 arbitrary email messages. StringIO and text file input is deprecated,
607 and string input fails early if non-ASCII characters are used, where
608 previously it would fail when the email was processed in a later step.
609
Nick Coghlan793ee1f2011-01-30 01:24:08 +0000610- Issue #10845: Mitigate the incompatibility between the multiprocessing
611 module on Windows and the use of package, zipfile or directory execution
612 by special casing main modules that actually *are* called __main__.py.
613
Éric Araujoac4e58e2011-01-29 20:32:11 +0000614- Issue #11045: Protect logging call against None argument.

617 commands.
618
Ned Deily806c9442011-01-29 18:43:56 +0000619- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
620 preventing a confusing hung appearance on OS X with the windows
621 obscured.
622
Ned Deily70063932011-01-29 18:29:01 +0000623- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the

633 with a None body.
634
Raymond Hettingera63a3122011-01-26 20:34:14 +0000635- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
636 keyword-only argument. The preceding positional argument was deprecated,
637 so it made no sense to add filter as a positional argument.
638
Raymond Hettinger512d2cc2011-01-25 21:32:39 +0000639- Issue #11004: Repaired edge case in deque.count().

642 with non-ASCII characters in their path names.
643

Victor Stinnerf2e439f2011-01-23 00:11:58 +0000651- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
Victor Stinner4ee65a92011-01-22 10:30:29 +0000652 filenames, at bootstrap, if the codec registry is not ready yet. It is still
653 possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
Victor Stinner137e0f02011-01-22 10:33:01 +0000654 for all file entries in the ZIP file.

662 a symbol named FSTAT.
663
Armin Ronacher8d96d772011-01-22 13:13:05 +0000664- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
665 encoding. This is the preferred encoding of PEP 3333 and the base encoding
666 of HTTP 1.1.
667
Armin Ronacher59531282011-01-22 13:44:22 +0000668- To match the behaviour of HTTP server, the HTTP client library now also
669 encodes headers with iso-8859-1 (latin1) encoding. It was already doing
670 that for incoming headers which makes this behaviour now consistent in
671 both incoming and outgoing direction.
672
Steven Bethardb0270112011-01-24 21:02:50 +0000673- Issue #9509: argparse now properly handles IOErrors raised by

Georg Brandl255abdd2011-01-16 14:17:26 +0000707- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
708 io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
709 translates newlines (\r\n => \n).

Georg Brandl255abdd2011-01-16 14:17:26 +0000765 continuation line in the formatted value has no leading white space and looks
766 like a header. Since Generator uses Header to format all headers, this check
767 is made for all headers in any serialized message at serialization time. This
768 provides protection against header injection attacks.
R. David Murray5b2d9dd2011-01-09 02:35:24 +0000769
Antoine Pitrou67b212e2011-01-08 09:55:31 +0000770- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially

Victor Stinner3ec899f2011-01-08 16:37:47 +0000785- Issue #1777412, #10827: Changed the rules for 2-digit years. The

788 otherwise. ``time.mktime`` and ``time.strftime`` now accept full range

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001417- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
1418 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001419 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00001420 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00001421 encoding and to encode command line arguments on this OS.

1424 filenames encoded to the filesystem encoding with the surrogateescape error

1426
Benjamin Peterson230b2062010-10-16 03:45:45 +00001427- Issue #9997: Don't let the name "top" have special significance in scope

Georg Brandl4fbc0d82010-11-13 13:25:40 +00001534 incorrectly validated some non-compliant applications as WSGI compliant; if
1535 your app validates with Python <3.2b1+, but not on this version, it is likely

1814 with a non-empty format string. This is an effort to future-proof user
1815 code. If a derived class does not currently implement __format__ but later
1816 adds its own __format__, it would most likely break user code that had
1817 supplied a format string. This will be changed to a DeprecationWaring in
1818 Python 3.3 and it will be an error in Python 3.4.

1822 wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.

1825 functions from the libc caused the methods .upper() and lower() to become
1826 locale aware and created subtly wrong results.
1827
Georg Brandl27a28582010-10-10 09:49:21 +00001828- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00001831- Issue #4617: Previously it was illegal to delete a name from the local
1832 namespace if it occurs as a free variable in a nested block. This limitation
1833 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
1834
Georg Brandl27a28582010-10-10 09:49:21 +00001835- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
1836 ``\UXXXXXXXX``, regardless of whether the character is printable or not.
1837 Also, the "backslashreplace" error handler now joins surrogate pairs into a
1838 single character on UCS-2 builds.

1843
Antoine Pitrou079ce542010-09-08 12:37:10 +00001844- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid

Éric Araujoef777bd2010-10-05 00:04:20 +00001873- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001874 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00001875 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00001876 replacement for old handle_accept() and avoids the user to call accept()
1877 directly.

Georg Brandl27a28582010-10-10 09:49:21 +00001901 retry the select() loop instead of bailing out. This is because select() can
1902 incorrectly report a socket as ready for reading (for example, if it received
1903 some data with an invalid checksum).

Raymond Hettingerfa11db02010-09-12 04:12:42 +00001983- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
Georg Brandl27a28582010-10-10 09:49:21 +00001984 it possible for the user to create self-referencing ordered dictionaries which
1985 become permanently uncollectable GC garbage. Reinstated the Python 3.1
Raymond Hettingerfa11db02010-09-12 04:12:42 +00001986 approach of using weakref proxies so that reference cycles never get created
1987 in the first place.
1988
Victor Stinnercb043522010-09-10 23:49:04 +00001989- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and

Amaury Forgeot d'Arc4b6fdf32010-09-07 21:31:17 +00002012- Issue #6394: os.getppid() is now supported on Windows. Note that it will

Georg Brandl27a28582010-10-10 09:49:21 +00002030 * Update the seed() method to use all of the bits in a string instead of just
2031 the hash value. This makes better use of the seed value and assures the
2032 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002033
Georg Brandl27a28582010-10-10 09:49:21 +00002034 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2035 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2036 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002037
2038 * Improved documentation of arguments to randrange(). Issue #9379.

2190 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference

Georg Brandl649971e2010-09-05 17:06:50 +00002229- Issue #9416: Fix some issues with complex formatting where the output with no
2230 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002231
2232 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

2576 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
2577 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
2578 returned a single u'\ufffd'.

2799 memory leak for some values large enough to cause overflow, and (4) a number
2800 of flaws that could lead to incorrectly rounded results.

Georg Brandl62069d32010-07-31 08:56:11 +00003490 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3491 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrou04f6a322010-04-05 21:40:07 +00003492
Raymond Hettingerc50846a2010-04-05 18:56:31 +00003493- Add functools.total_ordering() and functools.cmp_to_key().
3494
Georg Brandl62069d32010-07-31 08:56:11 +00003495- Issue #8257: The Decimal construct now accepts a float instance directly,
3496 converting that float to a Decimal of equal value:
Mark Dickinson089b00c2010-04-03 15:51:03 +00003497
3498 >>> Decimal(1.1)
3499 Decimal('1.100000000000000088817841970012523233890533447265625')
3500
Georg Brandl62069d32010-07-31 08:56:11 +00003501- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3502 directly.
Mark Dickinson98127c32010-04-03 11:18:52 +00003503
Georg Brandl62069d32010-07-31 08:56:11 +00003504- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3505 InvalidOperation instead of returning False. (Comparisons involving a quiet
3506 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3507 signaling NaNs remain unhashable.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003508
Georg Brandl62069d32010-07-31 08:56:11 +00003509- Issue #2531: Comparison operations between floats and Decimal instances now
3510 return a result based on the numeric values of the operands; previously they
3511 returned an arbitrary result based on the relative ordering of id(float) and
3512 id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
3513 comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +00003514
Raymond Hettinger9c01e442010-04-03 10:32:58 +00003515- Added a subtract() method to collections.Counter().
3516
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003517- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00003518 argument `-` which tells it to read files to compile from stdin. Each line is
3519 read on demand and the named file is compiled immediately. (Original patch by
3520 Piotr Ożarowski).
Barry Warsawd5f9bf52010-03-31 21:36:22 +00003521
Florent Xicluna806d8cf2010-03-30 19:34:18 +00003522- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3523 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandl62069d32010-07-31 08:56:11 +00003524 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna806d8cf2010-03-30 19:34:18 +00003525
Georg Brandl62069d32010-07-31 08:56:11 +00003526- Comparisons using one of <, <=, >, >= between a complex instance and a
3527 Fractions instance now raise TypeError instead of returning True/False. This
3528 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3529 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00003531- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some

Florent Xiclunafd1b0932010-03-28 00:25:02 +00003535- Issue #8205: Remove the "Modules" directory from sys.path when Python is
3536 running from the build directory (POSIX only).
3537
Antoine Pitrou910bd512010-03-22 20:11:09 +00003538- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandl62069d32010-07-31 08:56:11 +00003539 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3540 silenced.

Georg Brandl62069d32010-07-31 08:56:11 +00003542- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3543 is running in WOW64 mode on 64 bit Windows.

Antoine Pitrou3c0fac22010-03-26 19:36:14 +00003545- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
3546 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
3547 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +00003548
Victor Stinnere3a1f6d2010-03-22 01:58:35 +00003549- Issue #4282: Fix the main function of the profile module for a non-ASCII

3556
Benjamin Peterson00888932010-03-18 22:37:38 +00003557- Issue #8168: py_compile now handles files with utf-8 BOMS.
3558
Benjamin Peterson689a5582010-03-18 22:29:52 +00003559- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
3560 detected.
3561
Martin v. Löwis4b003072010-03-16 13:19:21 +00003562- Issue #6716/2: Backslash-replace error output in compilall.

Georg Brandl62069d32010-07-31 08:56:11 +00003569- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
3570 locale.
Matthias Klose82f60912010-03-15 13:46:04 +00003571
Georg Brandl62069d32010-07-31 08:56:11 +00003572- The internals of the subprocess module on POSIX systems have been replaced by
3573 an extension module (_posixsubprocess) so that the fork()+exec() can be done
3574 safely without the possibility of deadlock in multithreaded applications.
Gregory P. Smitha31f57c2010-03-14 06:52:18 +00003575
Georg Brandl62069d32010-07-31 08:56:11 +00003576- subprocess.Popen now has restore_signals and start_new_session features. The
3577 default of restore_signals=True is a new behavior compared to earlier Python
3578 versions. This means that signals such as SIGPIPE are not ignored by default
3579 in subprocesses launched by Python (Issue #1652).
Gregory P. Smith580d60c2010-03-14 07:13:25 +00003580
Florent Xiclunaf15351d2010-03-13 23:24:31 +00003581- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

Gerhard Häringf9cee222010-03-05 15:20:03 +00003593- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
3594 bugs and allows loading SQLite extensions from shared libraries.
3595
Ezio Melottida227042010-03-14 11:51:00 +00003596- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Georg Brandl62069d32010-07-31 08:56:11 +00003665- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
3666 position when calling `truncate()`. It would previously change the file
3667 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00003668 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3669
Antoine Pitroua32f9a22010-01-27 21:18:57 +00003670- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00003671 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
3672 archive. The new implementation is significantly faster and can be wrapped in
3673 a :class:`io.BufferedReader` object for more speedups. It also solves an
3674 issue where interleaved calls to `read()` and `readline()` give wrong results.
3675 Patch by Nir Aides.

Georg Brandl62069d32010-07-31 08:56:11 +00004011 loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
4012 PyPycLoader inherit from this class and provide implementations in relation to
4013 other methods required by the ABCs.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00004072- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
Georg Brandl62069d32010-07-31 08:56:11 +00004073 compared to other unix systems. In particular, os.getgroups() does not reflect
4074 any changes made using os.setgroups() but basicly always returns the same
4075 information as the id command. os.getgroups() can now return more than 16
4076 groups on MacOSX.

4102 Prior to this change, timezone adjustment in utctimetuple() could produce
4103 tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge

4108 aware ``datetime`` object is returned with ``tzinfo`` bound to a
4109 ``datetime.timezone`` instance constructed from the parsed offset. If both
4110 ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
4111 name, but ``%Z`` data without ``%z`` is discarded.

4115 ``datetime.timezone``, return fixed name and UTC offset from their
4116 ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
4117 returns ``None``. A class attribute, ``utc`` contains an instance

Mark Dickinson865e01a2009-05-07 16:37:01 +00004724- Issue #5914: Add new C API function PyOS_string_to_double, and
4725 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
4726
Eric Smith741191f2009-05-06 13:08:15 +00004727- Issue #3382: float.__format__, complex.__format__, and %-formatting
4728 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
4729 affects nan -> NAN and inf -> INF.
4730
Mark Hammond5a607a32009-05-06 08:04:54 +00004731- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
4732 in all operations, including splitdrive, split, etc. splitunc() now issues
4733 a PendingDeprecation warning.
4734
Eric Smith63376222009-05-05 14:04:18 +00004735- Issue #5920: For float.__format__, change the behavior with the
4736 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
4737 to be like 'g' but with at least one decimal point and with a
4738 default precision of 12. Previously, the behavior the same but with
4739 a default precision of 6. This more closely matches str(), and
4740 reduces surprises when adding alignment flags to the empty
4741 presentation type. This also affects the new complex.__format__ in
4742 the same way.
4743
Martin v. Löwis011e8422009-05-05 04:43:17 +00004744- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
4745
R. David Murrayb18500d2009-05-04 22:59:07 +00004746- Issue #5890: in subclasses of 'property' the __doc__ attribute was
4747 shadowed by classtype's, even if it was None. property now
4748 inserts the __doc__ into the subclass instance __dict__.
4749
Antoine Pitrou244651a2009-05-04 18:56:13 +00004750- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
4751 sequences. Patch by Nick Barnes and Victor Stinner.
4752
Martin v. Löwise0a2b722009-05-10 08:08:56 +00004753- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00004754
Benjamin Petersond2e0c792009-05-01 20:40:59 +00004755- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
4756 received a new method, detach(). detach() disconnects the underlying stream
4757 from the buffer or text IO and returns it.
4758
Mark Dickinson33841c32009-05-01 15:37:04 +00004759- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
4760 floats with absolute value over 1e50. Also remove length
4761 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
4762 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00004763
Eric Smith741191f2009-05-06 13:08:15 +00004764- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00004765 format(complex(1, 2./3), '.5') now produces a sensible result.
4766
Mark Dickinsond3ca5572009-04-29 18:47:07 +00004767- Issue #5864: Fix empty format code formatting for floats so that it
4768 never gives more than the requested number of significant digits.
4769
Eric Smith6dc46f52009-04-27 20:39:49 +00004770- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
4771 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
4772
Eric Smithcc32a112009-04-26 21:35:14 +00004773- Issue #5835: Deprecate PyOS_ascii_formatd.
4774
Martin v. Löwis71efeb72009-04-26 01:02:07 +00004775- Issue #4971: Fix titlecase for characters that are their own
4776 titlecase, but not their own uppercase.
4777
Benjamin Peterson193152c2009-04-25 01:08:45 +00004778- Issue #5283: Setting __class__ in __del__ caused a segfault.
4779
Mark Dickinsonad476da2009-04-23 19:14:16 +00004780- Issue #5816: complex(repr(z)) now recovers z exactly, even when
4781 z involves nans, infs or negative zeros.
4782
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00004783- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00004784
Mark Dickinsone6a076d2009-04-18 11:48:33 +00004785- Issue #1869 (and many duplicates): make round(x, n) correctly
4786 rounded for a float x, by using the decimal <-> binary conversions
4787 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
4788 consistently agrees with format(x, '.2f').
4789
Benjamin Petersonae937c02009-04-18 20:54:08 +00004790- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
4791 some builtin types.
4792
Eric Smith0923d1d2009-04-16 20:16:10 +00004793- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
4794
Eric Smith35e84722009-04-16 20:21:28 +00004795- Issue #5515: str.format() type 'n' combined with commas and leading
4796 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00004797
4798- Implement PEP 378, Format Specifier for Thousands Separator, for
4799 floats.
4800
Mark Dickinson3370cce2009-04-17 22:40:53 +00004801- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004802 1e11, not 1e12. This avoids printing 13 significant digits in
4803 situations where only 12 of them are correct. Example problem
4804 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
4805 long time.)
4806
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004807- Issue #1580: On most platforms, use a 'short' float repr: for a
4808 finite float x, repr(x) now outputs a string based on the shortest
4809 sequence of decimal digits that rounds to x. Previous behaviour was
4810 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00004811 Another minor difference is that the new repr switches to
4812 exponential notation at 1e16 instead of the previous 1e17; this
4813 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004814
4815 There's a new sys attribute sys.float_repr_style, which takes
4816 the value 'short' to indicate that we're using short float repr,
4817 and 'legacy' if the short float repr isn't available for one
4818 reason or another.
4819
4820 The float repr change involves incorporating David Gay's 'perfect
4821 rounding' code into the Python core (it's in Python/dtoa.c). As a
4822 secondary consequence, all string-to-float and float-to-string
4823 conversions (including all float formatting operations) will be
4824 correctly rounded on these platforms.
4825
Georg Brandl5f90d792010-08-01 22:31:05 +00004826 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00004827 this change does not apply.
4828
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00004829- Issue #5759: float() didn't call __float__ on str subclasses.
4830
Georg Brandlabc38772009-04-12 15:51:51 +00004831- The string.maketrans() function is deprecated; there is a new static method
4832 maketrans() on the bytes and bytearray classes. This removes confusion about
4833 the types string.maketrans() is supposed to work with, and mirrors the
4834 methods available on the str class.
4835
R. David Murraydc6da8a2009-04-09 22:16:43 +00004836- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
4837 its clarity and its speed.
4838
Georg Brandl65ce6ad2010-09-05 17:32:31 +00004839- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00004840 to avoid compiler warnings.
4841
Walter Dörwald8dc33d52009-05-06 14:41:26 +00004842- Issue #3739: The unicode-internal encoder now reports the number of characters
4843 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwis403117a2009-05-24 19:19:17 +00004855- Issue #5311: bdist_msi can now build packages that do not depend on a
4856 specific Python version.
4857
Raymond Hettingereb816952009-05-29 01:22:18 +00004858- Issue #5150: IDLE's format menu now has an option to strip trailing

Benjamin Peterson8f76b492009-04-03 22:22:42 +00004980- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
4981
Benjamin Peterson7fe98532009-04-02 00:33:55 +00004982- Issue #5499: The 'c' code for argument parsing functions now only accepts a
4983 byte, and the 'C' code only accepts a unicode character.
4984
Georg Brandl406b3d82009-04-11 21:24:37 +00004985- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

Georg Brandlab6f2f62009-03-31 04:16:10 +00004990- Fix a segfault when running test_exceptions with coverage, caused by
4991 insufficient checks in accessors of Exception.__context__.
4992
Guido van Rossum0ad59d42009-03-30 22:01:35 +00004993- Issue #5604: non-ASCII characters in module name passed to
4994 imp.find_module() were converted to UTF-8 while the path is
4995 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00004999- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
5000 the end sys.path, for compatibility with the system install of Python.
5001
Antoine Pitrou3a652b12009-03-23 18:52:06 +00005002- Issue #4688: Add a heuristic so that tuples and dicts containing only
5003 untrackable objects are not tracked by the garbage collector. This can
5004 reduce the size of collections and therefore the garbage collection overhead
5005 on long-running programs, depending on their particular use of datatypes.
5006
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00005007- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

5010
Mark Dickinsonbd792642009-03-18 20:06:12 +00005011- Issue #4258: Make it possible to use base 2**30 instead of base
5012 2**15 for the internal representation of integers, for performance
5013 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
5014 --enable-big-digits option to configure, which overrides the
5015 default. Add sys.int_info structseq to provide information about
5016 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00005128- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
5129 it now forces its argument to double before testing for infinity.
5130
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00005131- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
5132 returns a non-number type.
5133
Benjamin Peterson87618552009-02-08 15:00:52 +00005134- Issue #5182: Removed memoryview.__str__.
5135
Mark Dickinsonc008a172009-02-01 13:59:22 +00005136- Issue #1717: Removed builtin cmp() function, dropped tp_compare
5137 slot, the C API functions PyObject_Compare and PyUnicode_Compare and

5139 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00005140
Georg Brandl1cdd83c2009-04-05 20:24:29 +00005141- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00005142 were suppressing all exceptions. These include list() and bytearray().
5143
Mark Dickinson1124e712009-01-28 21:25:58 +00005144- Issue #4707: round(x, n) now returns an integer if x is an integer.
5145 Previously it returned a float.
5146
Antoine Pitroub52ec782009-01-25 16:34:23 +00005147- Issue #4753: By enabling a configure option named '--with-computed-gotos'
5148 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
5149 evaluation loop is compiled with a new dispatch mechanism which gives
5150 speedups of up to 20%, depending on the system, on various benchmarks.
5151
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00005152- Issue #4874: Most builtin decoders now reject unicode input.

5160 optional module state data.
5161
Mark Dickinson8055afd2009-01-17 10:04:45 +00005162- Issue #4910: Rename nb_long slot to nb_reserved, and change its
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005163 type to ``(void *)``.
Mark Dickinson8055afd2009-01-17 10:04:45 +00005164
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00005165- Issue #4935: The overflow checking code in the expandtabs() method common
5166 to str, bytes and bytearray could be optimized away by the compiler, letting
5167 the interpreter segfault instead of raising an error.
5168
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00005169- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5170 __next__ method.
5171
Mark Dickinsone5e298f2009-01-12 20:49:19 +00005172- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
5173 function no longer attempt to call the __long__ slot to convert an object
5174 to an integer. Only the __int__ and __trunc__ slots are examined.
5175
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00005176- Issue #4893: Use NT threading on CE.
5177

5179
Antoine Pitrouab868312009-01-10 15:40:25 +00005180- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
5181 common cases are optimized thanks to a dedicated fast path and a moderate
5182 amount of loop unrolling.
5183
Antoine Pitrou14b78f52009-01-09 22:27:08 +00005184- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5185 collecting the oldest generation) so that allocating lots of objects without
5186 destroying them does not show quadratic performance. Based on a proposal by
5187 Martin von Löwis at
5188 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
5189
Vinay Sajip6268cbc2009-01-21 00:19:28 +00005190- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00005191 having been closed (for instance, a read() call could return some
5192 previously buffered data). Patch by Dmitry Vasiliev.
5193
Antoine Pitrou05608432009-01-09 18:53:14 +00005194- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
5195 flag to work properly. Furthermore, when specifying -u, the text stdout
5196 and stderr streams have line-by-line buffering enabled (the default being
5197 to buffer arbitrary chunks of data).
5198
Raymond Hettinger35631532009-01-09 03:58:09 +00005199- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
5200 instead of ints (reducing its size from 4 to 8 times thereby reducing
5201 Python's overall memory).
5202
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005203- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5204 an existing .py counterpart, override the co_filename attributes of all
5205 code objects if the original filename is obsolete (which can happen if the
5206 file has been renamed, moved, or if it is accessed through different paths).
5207 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5208
Antoine Pitrouc3b39242009-01-03 16:59:18 +00005209- Issue #4580: Fix slicing of memoryviews when the item size is greater than
5210 one byte. Also fixes the meaning of len() so that it returns the number of
5211 items, rather than the size in bytes.
5212
Martin v. Löwis5c88d812009-01-02 20:47:48 +00005213- Issue #4075: Use OutputDebugStringW in Py_FatalError.
5214
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00005215- Issue #4747: When the terminal does not use utf-8, executing a script with
5216 non-ascii characters in its name could fail with a "SyntaxError: None" error.
5217
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005218- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
5219 to open file with a bytes filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00005220
Antoine Pitrou7ddda782009-01-01 15:35:33 +00005221- Issue #3680: Reference cycles created through a dict, set or deque iterator
5222 did not get collected.
5223
Nick Coghlanf1f2f682008-12-30 07:29:12 +00005224- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
5225 where the tp_hash and tp_dict slots are both NULL.
5226
Georg Brandlccc47b62008-12-28 11:44:14 +00005227- Issue #4759: None is now allowed as the first argument of
5228 bytearray.translate(). It was always allowed for bytes.translate().
5229
Skip Montanaro80072cb2008-12-23 03:51:14 +00005230- Added test case to ensure attempts to read from a file opened for writing
5231 fail.
5232
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00005233- Issue #3106: Speedup some comparisons (str/str and int/int).

5236 comprehensions. Original patch for list comprehensions by Neal Norwitz.
5237
Antoine Pitrou621601a2008-12-17 23:18:19 +00005238- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
5239 print elapsed times, not only when some objects are uncollectable /
5240 unreachable. Original patch by Neil Schemenauer.
5241
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00005242- Issue #3439: Add a bit_length method to int.
5243
Mark Dickinsonda2706b2008-12-11 18:03:03 +00005244- Issue #2173: When getting device encoding, check that return value of
5245 nl_langinfo is not the empty string. This was causing silent build
5246 failures on OS X.
5247
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00005248- Issue #4597: Fixed several opcodes that weren't always propagating
5249 exceptions.
5250
5251- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00005252 context manager returns a value that cannot be converted to a bool.
5253
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005254- Issue #4445: Replace "sizeof(PyBytesObject)" with
5255 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5256 bytes instances. On a typical machine this saves 3 bytes of memory
5257 (on average) per allocation of a bytes instance.
5258
Christian Heimesa872de52008-12-05 08:26:55 +00005259- Issue #4533: File read operation was dreadfully slow due to a slowly
5260 growing read buffer. Fixed by using the same growth rate algorithm as
5261 Python 2.x.
5262
Antoine Pitrou5504e892008-12-06 21:27:53 +00005263- Issue #4509: Various issues surrounding resize of bytearray objects to
5264 which there are buffer exports (e.g. memoryview instances).
5265
Georg Brandlf9734072008-12-07 15:30:06 +00005266- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5267 method on file objects with closefd=False. The file descriptor is still
5268 kept open but the file object behaves like a closed file. The ``FileIO``
5269 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00005271- Issue #4569: Interpreter crash when mutating a memoryview with an item size
5272 larger than 1.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00005278- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
5279 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5280 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5281 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00005886- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5887 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
5888 the same behaviour as test_ttkguionly (and now also test_tk) which is to
5889 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00005892 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00005893 from test support, which does the conversion.
