OL 2.13 is shaping up to be a great release! Thanks go to the devs for
the hard work on it and @bartvde for being the release manager.
The new TileManager  is promising, especially for mobile app
development. It is new code though and may still contain some bugs.
I would like to ask everyone, who hasn't done so yet, to test out with
their apps with 2.13 with the TileManager enabled (*before* the final
version has been released), especially people that use OL with GeoExt
(GE): one bug manifested itself through GE  (although the cause had
nothing to do with GE). Has anyone tested all GeoExt 1.1 examples with
OL 2.13 yet?
