The original CRM Online 2011 RTM build was 5.00.9688.34. This was updated to a new build (5.00.9688.56) on 1/14/2011.
It appears that another build has just been released. The new build is: 5.00.9688.65.
No word on what has changed, but the bar must be high now in the triage process; so the changes are more than likely limited to critical / blocking bugs only.
