Excellent writeup by my colleague. Insider fast is the way to see what is coming first. We have have a few customers ask us for exact drop dates for General availibility. On a monthly release cadence that is harder for us to do. However we definitely are signaling to those of you who are tracking the next release when we release Insider Fastthat we are getting closer :-).

VBSS and Meeting Info button in one release? You're spoiling us! That two regular user requests I can get off my back, good job!


Thanks Steve for the kind words. The Product team has been really pusahing these updates as fast as they can while trying to maintain quality. VbSS is definitely a big deal as our own informal internal testing continues to show that when users begin using VbSS as they default sharing technology, reliability measurably improves.
