26618 The 1.6 NEWS file can't be changed after the release is done, so here
26619 is some late-breaking news:

26695 Probably the most pervasive change is the addition of Unicode support.

26719   engine -- this is at least the fourth!).
26727 Deleting objects is now safe even for deeply nested data structures.

29559 - The httplib module is more robust when servers send a short response
29577 commands are automatically unbound when the widget is destroyed, but

33183 range() is that its representation (if the range contains many
33184 elements) is much more compact than that of range().  The disadvantage
33185 is that the result cannot be used to initialize a list object or for
33206 printed by assigning to sys.tracebacklimit.  The default is 1000.

33229 * When an object is printed by the print statement, its implementation
33230 of str() is used.  This means that classes can define __str__(self) to
33231 direct how their instances are printed.  This is different from
33233 representation of the instance.  (If __str__() is not defined, it

33263 the first time it is imported.
33272 * The array module is extended with 8-byte object swaps, the 'i'
33298 * The library is now split in several subdirectories: all stuff using
33299 stdwin is in Lib/stdwin, all SGI specific (or SGI Indigo or GL) stuff
33300 is in Lib/sgi, all Sun Sparc specific stuff is in Lib/sun4, and all

33376 bytes per string it is disabled by default.

33461 directory.  It is expected that this interface will be replaced by a
33463 backward compatible.  In other words, this part of the code is at most
33464 BETA level software!  (Note: the rest of Python is rock solid as ever!)

33567 the parser knows about the keyword so you must not use it as a
33574 * The following compatibility hack is removed: if a function was
33577 would be used as the arguments.  This is no longer supported.
33587 * If a class attribute is a user-defined function, a new kind of
33588 object is returned: an "unbound method".  This contains a pointer to
33589 the class and can only be called with a first argument which is a

33601 when an instance of the class is about to be destroyed.  This makes it

33606 is again about to be destroyed its __del__() method will be called
33626 similar to sprintf() in C.  The right argument is either a single

34541 The string value of each exception is now its name -- this makes it
34562 Philosophically, the change is quite radical (to me, anyway): a
34563 function is no longer called with either zero or one argument, which
34564 is a tuple if there appear to be more arguments.  Every function now
34565 has an argument list containing 0, 1 or more arguments.  This list is
34566 always implemented as a tuple, and it is a (run-time) error if a
34567 function is called with a different number of arguments than expected.

34574 (or more) was next to impossible.  This is now a piece of cake: you

34694 Here is a summary of the most important user-visible changes in 0.9.2,

34724   strtol() implementation is provided, but the strtod() provided
34748 	- f.readline() no longer restricts the line length, is faster,
34760 	- utime() replaces utimes() (the latter is not a POSIX name)
34775 - Added some modules and functionality to the "widget set" (which is
