Barry Warsaw cut and released Python 2.6 yesterday. Plenty of stuff has changed since 2.5 (including the docs in terms of how the look and the URLs).
In terms of 3.0, it looks like we will have another beta for it. A bunch of release blockers came up while we tried to get 2.6 out the door and need to be addressed. But hopefully it won't take too long to get it out the door.
