572 and was unreliable since tests or user programs could modify the interpreter
573 environment after Distutils set it. Instead, have Distutils set the the
574 deployment target only in the environment of each build subprocess. It is
575 still possible to globally override the default by setting
576 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be

578 was built.

Georg Brandl4fbc0d82010-11-13 13:25:40 +00002073- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
2074 the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002075 variable is not set, the locale encoding is ISO-8859-1, whereas most programs
Georg Brandl4fbc0d82010-11-13 13:25:40 +00002076 (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
Victor Stinnerf933e1a2010-10-20 22:58:25 +00002077 encoding and to encode command line arguments on this OS.

2080 filenames encoded to the filesystem encoding with the surrogateescape error

2082
Benjamin Peterson230b2062010-10-16 03:45:45 +00002083- Issue #9997: Don't let the name "top" have special significance in scope

Benjamin Peterson0dc97ed2010-09-21 21:28:47 +00002456- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other

2458 Py_Initialize().
2459
Georg Brandl27a28582010-10-10 09:49:21 +00002460- All SyntaxErrors now have a column offset and therefore a caret when the error

Georg Brandl27a28582010-10-10 09:49:21 +00002469- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2470 with a non-empty format string. This is an effort to future-proof user
2471 code. If a derived class does not currently implement __format__ but later
2472 adds its own __format__, it would most likely break user code that had
2473 supplied a format string. This will be changed to a DeprecationWaring in
2474 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrou1df15362010-09-13 14:16:46 +00002476- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
2477 re-created on a subsequent call to Py_Initialize(). The problem (a crash)
2478 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 +00002480- Issue #9210: Configure option --with-wctype-functions was removed. Using the
2481 functions from the libc caused the methods .upper() and lower() to become

Amaury Forgeot d'Arcba117ef2010-09-10 21:39:53 +00002487- Issue #4617: Previously it was illegal to delete a name from the local
2488 namespace if it occurs as a free variable in a nested block. This limitation
2489 of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).

Georg Brandl27a28582010-10-10 09:49:21 +00002491- Issue #9804: ascii() now always represents unicode surrogate pairs as a single

2493 Also, the "backslashreplace" error handler now joins surrogate pairs into a
2494 single character on UCS-2 builds.

Éric Araujoef777bd2010-10-05 00:04:20 +00002529- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002530 returning a (sock, addr) pair which is called when a connection has been
Georg Brandl27a28582010-10-10 09:49:21 +00002531 established with a new remote endpoint. This is supposed to be used as a
Giampaolo Rodolà977c7072010-10-04 21:08:36 +00002532 replacement for old handle_accept() and avoids the user to call accept()

Georg Brandl27a28582010-10-10 09:49:21 +00002557 retry the select() loop instead of bailing out. This is because select() can

Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002681- Updates to the random module:
2682
Georg Brandl27a28582010-10-10 09:49:21 +00002683 * Document which parts of the module are guaranteed to stay the same across
2684 versions and which parts are subject to change.
Raymond Hettinger435cb0f2010-09-06 23:36:31 +00002685
Georg Brandl27a28582010-10-10 09:49:21 +00002686 * Update the seed() method to use all of the bits in a string instead of just
2687 the hash value. This makes better use of the seed value and assures the
2688 seeding is platform independent. Issue #7889.
Raymond Hettinger05156612010-09-07 04:44:52 +00002689
Georg Brandl27a28582010-10-10 09:49:21 +00002690 * Improved the random()-->integer algorithm used in choice(), shuffle(),
2691 sample(), randrange(), and randint(). Formerly, it used int(n*random())
2692 which has a slight bias whenever n is not a power of two. Issue #9025.
Raymond Hettinger05156612010-09-07 04:44:52 +00002693
2694 * Improved documentation of arguments to randrange(). Issue #9379.

Gregory P. Smith13b55292010-09-06 08:30:23 +00002713- hashlib has two new constant attributes: algorithms_guaranteed and
2714 algorithms_avaiable that respectively list the names of hash algorithms
2715 guaranteed to exist in all Python implementations and the names of hash
2716 algorithms available in the current process.

Georg Brandl649971e2010-09-05 17:06:50 +00002821- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
2822 now removed, since their effect was inexistent in 3.x (the default encoding is

2845 return characters from the full Unicode range, even on narrow unicode builds
2846 (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
2847 in Python is that unicodedata.numeric() now returns the correct value for
2848 large code points, and repr() may consider more characters as printable.
2849
Victor Stinner6c00c142010-08-17 23:37:11 +00002850- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename

Georg Brandl649971e2010-09-05 17:06:50 +00002885- Issue #9416: Fix some issues with complex formatting where the output with no
2886 type specifier failed to match the str output:
Mark Dickinson5b65df72010-08-01 10:41:49 +00002887
2888 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,

Ezio Melotti57221d02010-07-01 07:32:02 +00003228- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
Georg Brandl62069d32010-07-31 08:56:11 +00003229 start byte and the continuation byte(s) are now considered invalid, instead of
3230 the number of bytes specified by the start byte. E.g.:
3231 '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
3232 with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
3233 even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
3234 returned a single u'\ufffd'.

3249 dealing with unary minus applied to a constant. The removed code was mutating
3250 the ST, causing a second compilation to fail.

Victor Stinner554f3f02010-06-16 23:33:54 +00003254 error handlers, the decoder only supports "strict" and "ignore" error
Georg Brandl62069d32010-07-31 08:56:11 +00003255 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +00003256
Victor Stinner25e8ec42010-06-25 00:02:38 +00003257- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
3258 "w*" format instead. Add tests for "w*" format.
3259
Victor Stinner06e49dd2010-06-13 18:21:50 +00003260- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
Georg Brandl62069d32010-07-31 08:56:11 +00003261 formats if the string contains a null byte/character. Write unit tests for
Victor Stinner06e49dd2010-06-13 18:21:50 +00003262 string formats.
3263
Georg Brandl62069d32010-07-31 08:56:11 +00003264- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
Nick Coghlan5e76e942010-06-12 13:42:46 +00003265 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
3266 location of the raised exception.
3267
Victor Stinner313a1202010-06-11 23:56:51 +00003268- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
3269 filenames and enable os.fsencode().
3270
Benjamin Peterson285a6892010-06-22 19:21:52 +00003271- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
3272
Georg Brandl62069d32010-07-31 08:56:11 +00003273- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
3274 interpreter with characters outside the Basic Multilingual Plane (higher than
3275 0x10000).
Antoine Pitroucc0cfd32010-06-11 21:46:32 +00003276
Georg Brandl62069d32010-07-31 08:56:11 +00003277- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
3278 TypeError instead of giving a DeprecationWarning when a float is parsed using
3279 the 'L' code (for long long). (All other integer codes already raise
3280 TypeError in this case.)
Mark Dickinsonc7301312010-06-10 16:05:10 +00003281
Victor Stinner600d3be2010-06-10 12:00:55 +00003282- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
3283 enable shortcuts for upper case encoding name. Add also a shortcut for
3284 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
3285
Georg Brandl62069d32010-07-31 08:56:11 +00003286- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
3287 doesn't support "char buffer" anymore in Python 3.
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003288
3289- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
Georg Brandl62069d32010-07-31 08:56:11 +00003290 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
Victor Stinner3dcb5ac2010-06-08 22:54:19 +00003291 like bytearray.
3292
Georg Brandl62069d32010-07-31 08:56:11 +00003293- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
Victor Stinner33109a12010-05-28 21:55:10 +00003294 used anymore and it was never documented.
3295
Georg Brandl62069d32010-07-31 08:56:11 +00003296- In str.format(), raise a ValueError when indexes to arguments are too large.

Georg Brandl62069d32010-07-31 08:56:11 +00003298- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
3299 integers n (including n = -909).
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +00003300
Georg Brandl62069d32010-07-31 08:56:11 +00003301- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
3302 of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
3303 easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
3304 equal value.
Mark Dickinsondc787d22010-05-23 13:33:13 +00003305
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003306- Issue #8748: Fix two issues with comparisons between complex and integer
3307 objects. (1) The comparison could incorrectly return True in some cases
Georg Brandl62069d32010-07-31 08:56:11 +00003308 (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
3309 (2) The comparison raised an OverflowError for large integers, leading to
3310 unpredictable exceptions when combining integers and complex objects in sets
3311 or dicts.
Mark Dickinsoncc6a9822010-05-21 14:55:26 +00003312
Victor Stinner7d79b8b2010-05-19 20:40:50 +00003313- Issue #8766: Initialize _warnings module before importing the first module.
3314 Fix a crash if an empty directory called "encodings" exists in sys.path.
3315
Victor Stinner9ca9c252010-05-19 16:53:30 +00003316- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
Victor Stinnere039ffe2010-08-15 09:33:08 +00003317 encoding and surrogateescape error handler instead of the locale encoding to
Georg Brandl62069d32010-07-31 08:56:11 +00003318 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
Victor Stinner9ca9c252010-05-19 16:53:30 +00003319
Georg Brandl62069d32010-07-31 08:56:11 +00003320- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
3321 of strict) error handler to escape surrogates.
Victor Stinner372ac5e2010-05-17 01:26:01 +00003322
Victor Stinnerae6265f2010-05-15 16:27:27 +00003323- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
3324 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Georg Brandl62069d32010-07-31 08:56:11 +00003325 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +00003326 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +00003327
Victor Stinner59e62db2010-05-15 13:14:32 +00003328- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
Georg Brandl62069d32010-07-31 08:56:11 +00003329 error handler, not only the default error handler (strict).
Victor Stinner59e62db2010-05-15 13:14:32 +00003330
Victor Stinnerb744ba12010-05-15 12:27:16 +00003331- Issue #8610: Load file system codec at startup, and display a fatal error on
Georg Brandl62069d32010-07-31 08:56:11 +00003332 failure. Set the file system encoding to utf-8 (instead of None) if getting
Victor Stinnerb744ba12010-05-15 12:27:16 +00003333 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
3334
Victor Stinner0964ee12010-04-30 16:48:45 +00003335- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
Georg Brandl62069d32010-07-31 08:56:11 +00003336 PyUnicode_FromString() to support surrogates in the filename and use the right
3337 encoding.

Georg Brandl8569e582010-05-19 20:57:08 +00003339- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
3340
Georg Brandl62069d32010-07-31 08:56:11 +00003341- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
Victor Stinnerb9a20ad2010-04-30 16:37:52 +00003342
Benjamin Petersonfb886362010-04-24 18:21:17 +00003343- Issue #8419: Prevent the dict constructor from accepting non-string keyword
3344 arguments.
3345
Victor Stinner14284c22010-04-23 12:02:30 +00003346- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
Georg Brandl62069d32010-07-31 08:56:11 +00003347 indirectly Python signal handlers anymore because mywrite() ignores exceptions

3615 `va_copy`, but available on all python platforms.
3616
Mark Dickinsone6fc7402010-08-06 18:55:26 +00003617- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
3618 instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
3619 "step = -step" when reversing a slice.

3641 PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
3642 'L' format code. This will become a TypeError in a future version of Python,
Mark Dickinsonde604012010-01-01 19:27:32 +00003643 to match the behaviour of the other integer format codes.

Antoine Pitrou3060c452010-08-13 16:27:38 +00003748 simply clearing the entire cache on overflow to forgetting the least recently
3749 used cached compiled regular expressions. This is a performance win for
Georg Brandl62069d32010-07-31 08:56:11 +00003750 applications that use a lot of regular expressions and limits the impact of
3751 the performance hit anytime the cache is exceeded.

3764 module is renamed to `_datetime` and if available, overrides all classes
3765 defined in datetime with fast C impementation. Python implementation is based
3766 on the original python prototype for the datetime module by Tim Peters with
3767 minor modifications by the PyPy project. The test suite now tests `datetime`

4166 return a result based on the numeric values of the operands; previously they
4167 returned an arbitrary result based on the relative ordering of id(float) and

Barry Warsawd5f9bf52010-03-31 21:36:22 +00004173- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandl62069d32010-07-31 08:56:11 +00004174 argument `-` which tells it to read files to compile from stdin. Each line is

4184 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4185 <=> complex, and complex <=> complex comparisons.

Georg Brandl62069d32010-07-31 08:56:11 +00004232- subprocess.Popen now has restore_signals and start_new_session features. The
4233 default of restore_signals=True is a new behavior compared to earlier Python
4234 versions. This means that signals such as SIGPIPE are not ignored by default
4235 in subprocesses launched by Python (Issue #1652).

4322 position when calling `truncate()`. It would previously change the file
4323 position to the given argument, which goes against the tradition of
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00004324 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Antoine Pitroua32f9a22010-01-27 21:18:57 +00004326- Issue #7610: Reworked implementation of the internal
Georg Brandl62069d32010-07-31 08:56:11 +00004327 :class:`zipfile.ZipExtFile` class used to represent files stored inside an
4328 archive. The new implementation is significantly faster and can be wrapped in
4329 a :class:`io.BufferedReader` object for more speedups. It also solves an
4330 issue where interleaved calls to `read()` and `readline()` give wrong results.
4331 Patch by Nir Aides.

Georg Brandl62069d32010-07-31 08:56:11 +00004729 compared to other unix systems. In particular, os.getgroups() does not reflect

5291
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00005292- In unittest, using a skipping decorator on a class is now equivalent to

5297
Antoine Pitrou61f77b52009-05-24 15:46:13 +00005298- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
5299 than an int, which makes some operations possible under 64-bit Linux (e.g.
5300 DN_MULTISHOT with F_NOTIFY).
5301
Antoine Pitrou716c4442009-05-23 19:04:03 +00005302- Issue #5761: Add the name of the underlying file to the repr() of various

5323
Antoine Pitroue4501852009-05-14 18:55:55 +00005324- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
5325 library. This means, for example, that opening an UTF-16 text file in
5326 append mode doesn't add a BOM at the end of the file if the file isn't
5327 empty.
5328
R. David Murray74b89242009-05-13 17:33:03 +00005329- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

5332
Georg Brandl5f90d792010-08-01 22:31:05 +00005333- Issue #5955: aifc's close method did not close the file it wrapped,
R. David Murray99352742009-05-07 18:24:38 +00005334 now it does. This also means getfp method now returns the real fp.

5377Core and Builtins
5378-----------------
5379
Mark Dickinson865e01a2009-05-07 16:37:01 +00005380- Issue #5914: Add new C API function PyOS_string_to_double, and
5381 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
5382
Eric Smith741191f2009-05-06 13:08:15 +00005383- Issue #3382: float.__format__, complex.__format__, and %-formatting
5384 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
5385 affects nan -> NAN and inf -> INF.
5386
Mark Hammond5a607a32009-05-06 08:04:54 +00005387- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
5388 in all operations, including splitdrive, split, etc. splitunc() now issues
5389 a PendingDeprecation warning.
5390
Eric Smith63376222009-05-05 14:04:18 +00005391- Issue #5920: For float.__format__, change the behavior with the
5392 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
5393 to be like 'g' but with at least one decimal point and with a
5394 default precision of 12. Previously, the behavior the same but with
5395 a default precision of 6. This more closely matches str(), and
5396 reduces surprises when adding alignment flags to the empty
5397 presentation type. This also affects the new complex.__format__ in
5398 the same way.
5399
Martin v. Löwis011e8422009-05-05 04:43:17 +00005400- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
5401
R. David Murrayb18500d2009-05-04 22:59:07 +00005402- Issue #5890: in subclasses of 'property' the __doc__ attribute was
5403 shadowed by classtype's, even if it was None. property now
5404 inserts the __doc__ into the subclass instance __dict__.
5405
Antoine Pitrou244651a2009-05-04 18:56:13 +00005406- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
5407 sequences. Patch by Nick Barnes and Victor Stinner.
5408
Martin v. Löwise0a2b722009-05-10 08:08:56 +00005409- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00005410
Benjamin Petersond2e0c792009-05-01 20:40:59 +00005411- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
5412 received a new method, detach(). detach() disconnects the underlying stream
5413 from the buffer or text IO and returns it.
5414
Mark Dickinson33841c32009-05-01 15:37:04 +00005415- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
5416 floats with absolute value over 1e50. Also remove length
5417 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
5418 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00005419
Eric Smith741191f2009-05-06 13:08:15 +00005420- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00005421 format(complex(1, 2./3), '.5') now produces a sensible result.
5422
Mark Dickinsond3ca5572009-04-29 18:47:07 +00005423- Issue #5864: Fix empty format code formatting for floats so that it
5424 never gives more than the requested number of significant digits.
5425
Eric Smith6dc46f52009-04-27 20:39:49 +00005426- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
5427 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
5428
Eric Smithcc32a112009-04-26 21:35:14 +00005429- Issue #5835: Deprecate PyOS_ascii_formatd.
5430
Martin v. Löwis71efeb72009-04-26 01:02:07 +00005431- Issue #4971: Fix titlecase for characters that are their own
5432 titlecase, but not their own uppercase.
5433
Benjamin Peterson193152c2009-04-25 01:08:45 +00005434- Issue #5283: Setting __class__ in __del__ caused a segfault.
5435
Mark Dickinsonad476da2009-04-23 19:14:16 +00005436- Issue #5816: complex(repr(z)) now recovers z exactly, even when
5437 z involves nans, infs or negative zeros.
5438
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00005439- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00005440
Mark Dickinsone6a076d2009-04-18 11:48:33 +00005441- Issue #1869 (and many duplicates): make round(x, n) correctly
5442 rounded for a float x, by using the decimal <-> binary conversions
5443 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
5444 consistently agrees with format(x, '.2f').
5445
Benjamin Petersonae937c02009-04-18 20:54:08 +00005446- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
5447 some builtin types.
5448
Eric Smith0923d1d2009-04-16 20:16:10 +00005449- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
5450
Eric Smith35e84722009-04-16 20:21:28 +00005451- Issue #5515: str.format() type 'n' combined with commas and leading
5452 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00005453
5454- Implement PEP 378, Format Specifier for Thousands Separator, for
5455 floats.
5456
Mark Dickinson3370cce2009-04-17 22:40:53 +00005457- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005458 1e11, not 1e12. This avoids printing 13 significant digits in
5459 situations where only 12 of them are correct. Example problem
5460 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
5461 long time.)
5462
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005463- Issue #1580: On most platforms, use a 'short' float repr: for a
5464 finite float x, repr(x) now outputs a string based on the shortest
5465 sequence of decimal digits that rounds to x. Previous behaviour was
5466 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00005467 Another minor difference is that the new repr switches to
5468 exponential notation at 1e16 instead of the previous 1e17; this
5469 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005470
5471 There's a new sys attribute sys.float_repr_style, which takes
5472 the value 'short' to indicate that we're using short float repr,
5473 and 'legacy' if the short float repr isn't available for one
5474 reason or another.
5475
5476 The float repr change involves incorporating David Gay's 'perfect
5477 rounding' code into the Python core (it's in Python/dtoa.c). As a
5478 secondary consequence, all string-to-float and float-to-string
5479 conversions (including all float formatting operations) will be
5480 correctly rounded on these platforms.
5481
Georg Brandl5f90d792010-08-01 22:31:05 +00005482 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00005483 this change does not apply.
5484
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00005485- Issue #5759: float() didn't call __float__ on str subclasses.
5486
Georg Brandlabc38772009-04-12 15:51:51 +00005487- The string.maketrans() function is deprecated; there is a new static method
5488 maketrans() on the bytes and bytearray classes. This removes confusion about
5489 the types string.maketrans() is supposed to work with, and mirrors the
5490 methods available on the str class.
5491
R. David Murraydc6da8a2009-04-09 22:16:43 +00005492- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
5493 its clarity and its speed.
5494
Georg Brandl65ce6ad2010-09-05 17:32:31 +00005495- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
Matthias Klose091c7b12009-04-07 13:24:27 +00005496 to avoid compiler warnings.
5497
Walter Dörwald8dc33d52009-05-06 14:41:26 +00005498- Issue #3739: The unicode-internal encoder now reports the number of characters
5499 consumed like any other encoder (instead of the number of bytes).

5580 results in a handle_expt_event call, not handle_read_event, and POLLERR
5581 and POLLNVAL now call handle_close, not handle_expt_event. Also,
5582 dispatcher now has an 'ignore_log_types' attribute for suppressing
5583 log messages, which is set to 'warning' by default.

5659 untrackable objects are not tracked by the garbage collector. This can
5660 reduce the size of collections and therefore the garbage collection overhead
5661 on long-running programs, depending on their particular use of datatypes.

5732 forever on incomplete input. That caused tarfile.open() to hang when used
5733 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
5734 partial bzip2 compressed data.
5735

5856 instead of ints (reducing its size from 4 to 8 times thereby reducing
5857 Python's overall memory).
5858
Antoine Pitroud35cbf62009-01-06 19:02:24 +00005859- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
5860 an existing .py counterpart, override the co_filename attributes of all
5861 code objects if the original filename is obsolete (which can happen if the
5862 file has been renamed, moved, or if it is accessed through different paths).
5863 Patch by Ziga Seilnacht and Jean-Paul Calderone.
5864

5909
Mark Dickinsonfd24b322008-12-06 15:33:31 +00005910- Issue #4445: Replace "sizeof(PyBytesObject)" with
5911 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
5912 bytes instances. On a typical machine this saves 3 bytes of memory
5913 (on average) per allocation of a bytes instance.
5914
Christian Heimesa872de52008-12-05 08:26:55 +00005915- Issue #4533: File read operation was dreadfully slow due to a slowly

5917 Python 2.x.
5918
Antoine Pitrou5504e892008-12-06 21:27:53 +00005919- Issue #4509: Various issues surrounding resize of bytearray objects to

5921
Georg Brandlf9734072008-12-07 15:30:06 +00005922- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
5923 method on file objects with closefd=False. The file descriptor is still
5924 kept open but the file object behaves like a closed file. The ``FileIO``
5925 object also got a new readonly attribute ``closefd``.

5935 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5936 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5937 of using the replace error handler in PyUnicode_DecodeUTF8().

6256
Antoine Pitrou08838b62009-01-21 00:55:13 +00006257- Issue #5008: When a file is opened in append mode with the new IO library,
6258 do an explicit seek to the end of file (so that e.g. tell() returns the
6259 file size rather than 0). This is consistent with the behaviour of the

6290 appropriately when it is being used via socket.makefile() objects
6291 rather than delaying the close by waiting for garbage collection to do it.
6292
Raymond Hettingerb8baf632009-01-14 02:20:07 +00006293- Issue #1696199: Add collections.Counter() for rapid and convenient
