21979   nb_float slot, rather than simply checking whether it has a non-NULL
21982 - The imp module now has ways to acquire and release the "import
21983   lock": imp.acquire_lock() and imp.release_lock().  Note: this is a
21984   reentrant lock, so releasing the lock only truly releases it when

22094   for mixed-type comparisons in the last paragraph doesn't apply, if
22106   sequence is heterogeneous, or the dict has mixed-type keys.  [This

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

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

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,

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

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

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

30329 same time, it is documented...:-( ).
30334 - More changes to import: the site.py module is now imported by
30335 default when Python is initialized; use -S to disable it.  The site.py

32635 bugs, and send me patches based on the previous release -- which I
32640 documentation (if you're anxious enough :-).  In this case it was not
32646 by Matt Conway, is available as tkinter-doc.tar.gz from the Python
32657     - More flexible operator overloading for user-defined classes
32660     - Classes can define methods named __getattr__, __setattr__ and
32663     - Classes can define method __call__ so instances can be called
32669     - The Makefiles (for the base interpreter as well as for extensions)
32673     - Passing the interpreter a .pyc file as script argument will execute
32674     the code in that file.  (On the Mac such files can be double-clicked!)

32677     of Python programs -- look in Demo/freeze
32679     - Improved h2py script (in Demo/scripts) follows #includes and
32682     - New module compileall generates .pyc files for all modules in a

32712     - sockets now have a setblocking() method
32714     - sockets no longer have an allowbroadcast() method
32716     - socket methods send() and sendto() return byte count
32721     - types.py defines standard names for built-in types, e.g. StringType
32723     - urlparse.py parses URLs according to the latest Internet draft
32725     - uu.py does uuencode/uudecode (not the fastest in the world, but
32726     quicker than installing uuencode on a non-UNIX machine :-)
32728     - New, faster and more powerful profile module.py
32730     - mhlib.py provides interface to MH folders and messages
32736     - newgetargs() supports optional arguments and improved error messages

32750     - Make variable OPT is passed on to sub-Makefiles
32752     - An init<module>() routine may signal an error by not entering
32755     - For long module names, instead of foobarbletchmodule.c you can
32758     - getintvalue() and getfloatvalue() try to convert any object
32761     - All the [new]getargs() formats that retrieve an integer value
32764     - C function listtuple() converts list to tuple, fast
32766     - You should now call sigcheck() instead of intrcheck();
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,

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
34712   dramatic improvement of start-up time

34714   strings, looking up single-character keys, and looking up global
34716 - Interrupting a print operation raises KeyboardInterrupt instead of
34718 - Fixed various portability problems (it now passes gcc with only
34719   warnings -- more Standard C compatibility will be provided in later
34721 - Source is prepared for porting to MS-DOS
34722 - Numeric constants are now checked for overflow (this requires
