23371   unix pathnames and MacPython-OS9 always uses colon-separated Mac pathnames
23374 - New Carbon modules Help and AH give access to the Carbon Help Manager.
23380 - OSA support has been redesigned and the generated Python classes now
23383 - MacPython no longer maps both \r and \n to \n on input for any text file.
23386 - The default encoding for Python sourcefiles in MacPython-OS9 is no longer

23985   the return value must be -1, 0, 1; an arbitrary number <0 or >0 is
23987   Python 2.3; even later, we may use -2 to indicate errors and +2 for

24070   *except* for built-in types, which are still rendered as <type
24074 - The repr() of new-style objects is now always <Foo object at XXX>;
24077 - For new-style classes, what was previously called __getattr__ is now
24082   access, you can use __getattribute__ (for new-style classes).  If
24086 - The __class__ attribute of new-style objects can be assigned to.
24087   The new class must have the same C-level object layout as the old
24090 - The built-in file type can be subclassed now.  In the usual pattern,
24091   "file" is the name of the built-in type, and file() is a new built-in
24092   constructor, with the same signature as the built-in open() function.
24095 - Previously, __new__ would only see sequential arguments passed to
24100 - Previously, hash() applied to an instance of a subclass of str or
24103 - Previously, an operation on an instance of a subclass of an

24121   makes unicode() behave like str() when applied to non-string/buffer
24124 - PyFile_WriteObject now passes Unicode objects to the file's write
24125   method. As a result, all file-like objects which may be the target
24129 - Thread scheduling on Solaris should be improved; it is no longer

24184 - Large file support (LFS) is now automatic when the platform supports
24192 - The configure script now supplies plausible defaults in a
24193   cross-compilation environment.  This doesn't mean that the supplied
24194   values are always correct, or that cross-compilation now works
24195   flawlessly -- but it's a first step (and it shuts up most of
24198 - The Unix build is now a bit less chatty, courtesy of the parser
24200   using "make -s", thanks to a -q option to setup.py.
24203 -----
24205 - The "structmember" API now supports some new flag bits to deny read
24209 -------------
24211 - Compaq's iPAQ handheld, running the "familiar" Linux distribution
24215 -----
24217 - The "classic" standard tests, which work by comparing stdout to
24218   an expected-output file under Lib/test/output/, no longer stop at
24220   variant of ndiff-style comparison is used to report all differences.
24223 - The unittest-based standard tests now use regrtest's test_main()
24224   convention, instead of running as a side-effect of merely being
24228 - regrtest.py is much better integrated with unittest and doctest now,

24234 - Large file support now also works for files > 4GB, on filesystems
24242 *Release Date: 07-Sep-2001*

24256 - The builtin dir() now returns more information, and sometimes much
24273 - Overflowing operations on plain ints now return a long int rather
24275   237.  You can use -Wdefault::OverflowWarning to enable a warning for
24276   this situation, and -Werror::OverflowWarning to revert to the old
24279 - A new command line option, -Q<arg>, is added to control run-time
24281   values are -Qold, -Qwarn, -Qwarnall, and -Qnew.  The default is
24282   -Qold, meaning the / operator has its classic meaning and no
24283   warnings are issued.  Using -Qwarn issues a run-time warning about
24284   all uses of classic division for int and long arguments; -Qwarnall
24288   obsolete in 2.2c1 -- -Qnew has global effect in 2.2] ::
24290     Using -Qnew is questionable; it turns on new division by default, but
24291     only in the __main__ module.  You can usefully combine -Qwarn or
24292     -Qwarnall and -Qnew: this gives the __main__ module new division, and
24295 - Many built-in types can now be subclassed.  This applies to int,
24298   Note that restrictions apply when subclassing immutable built-in
24305 - The dictionary constructor now takes an optional argument, a
24306   mapping-like object, and initializes the dictionary from its
24309 - A new built-in type, super, has been added.  This facilitates making
24313 - A new built-in type, property, has been added.  This enables the
24315   getter and setter functions (or only one of these for read-only or
24316   write-only attributes), without the need to override __getattr__.
24319 - The syntax of floating-point and imaginary literals has been
24325 - An old tokenizer bug allowed floating point literals with an incomplete
24326   exponent, such as 1e and 3.1e-.  Such literals now raise SyntaxError.

24382 - Note that PyLong_AsDouble can fail!  This has always been true, but no
24387       if (x == -1.0 && PyErr_Occurred()) {
24391 - The GC API has been changed.  Extensions that use the old API will still
24395     - rename Py_TPFLAGS_GC to PyTPFLAGS_HAVE_GC
24397     - use PyObject_GC_New or PyObject_GC_NewVar to allocate objects and
24400     - rename PyObject_GC_Init to PyObject_GC_Track and PyObject_GC_Fini
24403     - remove PyGC_HEAD_SIZE from object size calculations
24405     - remove calls to PyObject_AS_GC and PyObject_FROM_GC
24407 - Two new functions: PyString_FromFormat() and PyString_FromFormatV().

25661   distutils-based setup.py script now takes care of building most
25667 - Python should now build out of the box on Cygwin.  If it doesn't,
25670 - Python now always uses its own (renamed) implementation of getopt()
25671   -- there's too much variation among C library getopt()

26616 --------------------------------------------
26619 is some late-breaking news:
26627 strings: the string.encode() (which is also present on 8-bit strings
26628 !) allows using them for 8-bit strings too, e.g. to convert files from

26909 implementation used -1; changing to None would break existing code.)

30532 - Fixed a nasty bug in cStringIO.c when code was actually using the
30536 - For those who think they need it, there's a "user.py" module.  This
30537 is *not* imported by default, but can be imported to run user-specific

32777 - Sometimes the format operator (string%expr) would drop the last
32780 - Tokenizer looped when last line did not end in \n
32782 - Bug when triple-quoted string ended in quote plus newline
32784 - Typo in socketmodule (listen) (== instead of =)
32786 - typing vars() at the >>> prompt would cause recursive output

34416 - A function with explicit variable-length argument list can be declared
34418 - Code tracing and profiling features have been added, and two source
34419   code debuggers are provided in the library (pdb.py, tty-oriented,
34420   and wdb, window-oriented); you can now step through Python programs!

34570 you want to write variadic functions -- functions that may be called
34576 tuple, and check its length -- it will be of size 0 if there are no

34608 arguments go undetected at first -- when the function tries to use the
34613 Two other rules and a new built-in function handle conversion between
34626 A new built-in function, apply(), was added to support functions that
34633 	function(tuple[0], tuple[1], ..., tuple[len(tuple)-1])
34638 values (as in C++ or Modula-3), or a "rest" argument to receive the
34639 remaining arguments of a variable-length argument list.

34710 - Option "-c command" to execute statements from the command line
34711 - Compiled versions of modules are cached in ".pyc" files, giving a
