@Flemming- Unfortunately, this is a bit of quality control issue. RadEditor and RadWindow "Prometheus" need a little more attention before they're placed in the final build, but those teams will not leave until that's done tonight (BG time).
@John- You may want to check out the reveal page from the Q2 game
. That lists all of the coming updates in Q2 and has links to demos of RadGrid 5. As for the "Q" naming, I'd suggest you check-out this old blog post
to understand how that works.
