The latest Extension Library release just came out! All the bug fixes we talked about in the forum are in, I know that some of you were impatiently waiting :-) It also contains all the fixes coming from the Upgrade Pack 1, also released this week.
It has a known issue in the SBT and Lotuslive, as the LL files API just changed and we didn't have time to adapt. We'll probably make available a new release next week with this fix in, at least.
Enjoy!
