Clearly a need for a new document. We don't want to startle people who 
don't want to get involved in version wars (probably 98.5% of all users 
aren't even aware of "What's New", since they use a Python installed by 
someone else, typically their computer vendor or Linux/UNIX distro team).

At the same time we should flag the fact that upcoming changes are 
indeed in the works. Possibly a "3.0 Design Snapshot" whose title makes 
it clear this is a moving target and, among other things, whose content 
points the user at a definitive (set of) URL(s) for the latest information.

Putting this information in "What's New" (except possibly for mentioning 
the creation of this new document) would create unnecessary FUD.
