2998 -----------------
3000 - weakref.ref is now the type object also known as
3001   weakref.ReferenceType; it can be subclassed like any other new-style
3002   class.  There's less per-entry overhead in WeakValueDictionary
3005 - Bug #951851: Python crashed when reading import table of certain
3008 - Bug #215126.  The locals argument to eval(), execfile(), and exec now

4702   falling back to the default compare-object-addresses strategy, these
4710   for mixed-type comparisons in the last paragraph doesn't apply, if
4722   sequence is heterogeneous, or the dict has mixed-type keys.  [This

6900 - A new command line option, -Q<arg>, is added to control run-time
6902   values are -Qold, -Qwarn, -Qwarnall, and -Qnew.  The default is

6904   warnings are issued.  Using -Qwarn issues a run-time warning about
6905   all uses of classic division for int and long arguments; -Qwarnall
6909   obsolete in 2.2c1 -- -Qnew has global effect in 2.2] ::
6911     Using -Qnew is questionable; it turns on new division by default, but
6912     only in the __main__ module.  You can usefully combine -Qwarn or
6913     -Qwarnall and -Qnew: this gives the __main__ module new division, and

6937   write-only attributes), without the need to override __getattr__.
6940 - The syntax of floating-point and imaginary literals has been
6946 - An old tokenizer bug allowed floating point literals with an incomplete
6947   exponent, such as 1e and 3.1e-.  Such literals now raise SyntaxError.

12955 - More changes to import: the site.py module is now imported by
12956 default when Python is initialized; use -S to disable it.  The site.py

15213 - Dynamic loading of modules using shared libraries is supported for
15216 - Support "O&", "[...]" and "{...}" in mkvalue().
15218 - Extension to findmethod(): findmethodinchain() (where a chain is a
15221 methodlist structure rather than just to the function name -- this
15222 saves copying flags etc. into the (short-lived) method object.
15224 - The callable() function is now public.
15226 - Object types can define a few new operations by setting function
15249 ever -- including Windows NT.  Makefiles or projects for a variety of

17191 you want to write variadic functions -- functions that may be called
17197 tuple, and check its length -- it will be of size 0 if there are no

17229 arguments go undetected at first -- when the function tries to use the
17234 Two other rules and a new built-in function handle conversion between
17247 A new built-in function, apply(), was added to support functions that
17254 	function(tuple[0], tuple[1], ..., tuple[len(tuple)-1])
17259 values (as in C++ or Modula-3), or a "rest" argument to receive the

17330 - Mixed arithmetic is supported, 1 compares equal to 1.0, etc.
17331 - Option "-c command" to execute statements from the command line
17332 - Compiled versions of modules are cached in ".pyc" files, giving a
17333   dramatic improvement of start-up time
17334 - Other, smaller speed improvements, e.g., extracting characters from
17335   strings, looking up single-character keys, and looking up global
17337 - Interrupting a print operation raises KeyboardInterrupt instead of
17339 - Fixed various portability problems (it now passes gcc with only
17340   warnings -- more Standard C compatibility will be provided in later
17342 - Source is prepared for porting to MS-DOS
17343 - Numeric constants are now checked for overflow (this requires
17344   standard-conforming strtol() and strtod() functions; a correct
17349 2. Changes to the built-in types, functions and modules
17351 - New module socket: interface to BSD socket primitives
17352 - New modules pwd and grp: access the UNIX password and group databases
17353 - (SGI only:) New module "fm" interfaces to the SGI IRIX Font Manager
17354 - (SGI only:) New module "fl" interfaces to Mark Overmars' FORMS library
17355 - New numeric type: long integer, for unlimited precision
17356 	- integer constants suffixed with 'L' or 'l' are long integers
17357 	- new built-in function long(x) converts int or float to long
17358 	- int() and float() now also convert from long integers
17359 - New built-in function:
17360 	- pow(x, y) returns x to the power y
17361 - New operation and methods for lists:
17362 	- l*n returns a new list consisting of n concatenated copies of l
17363 	- l.remove(x) removes the first occurrence of the value x from l
17364 	- l.index(x) returns the index of the first occurrence of x in l
17365 	- l.reverse() reverses l in place
17366 - New operation for tuples:
17367 	- t*n returns a tuple consisting of n concatenated copies of t
17368 - Improved file handling:
17369 	- f.readline() no longer restricts the line length, is faster,
17371 	- f.read() without arguments reads the entire (rest of the) file
17372 	- mixing of print and sys.stdout.write() has different effect
17373 - New methods for files:
17374 	- f.readlines() returns a list containing the lines of the file,
17376 	- f.flush(), f.tell(), f.seek() call their stdio counterparts
17377 	- f.isatty() tests for "tty-ness"
17378 - New posix functions:
17379 	- _exit(), exec(), fork(), getpid(), getppid(), kill(), wait()
17380 	- popen() returns a file object connected to a pipe
17381 	- utime() replaces utimes() (the latter is not a POSIX name)
17382 - New stdwin features, including:
17383 	- font handling
17384 	- color drawing
17385 	- scroll bars made optional
17386 	- polygons
17387 	- filled and xor shapes
17388 	- text editing objects now have a 'settext' method
17393 - Name change: the functions path.cat and macpath.cat are now called
17395 - Added new modules: formatter, mutex, persist, sched, mainloop
17396 - Added some modules and functionality to the "widget set" (which is
17399 - Fixed module testall to work non-interactively
17400 - Module string:
17401 	- added functions join() and joinfields()
17402 	- fixed center() to work correct and make it "transitive"
17403 - Obsolete modules were removed: util, minmax
17404 - Some modules were moved to the demo directory
