New bits have been trickling out since we shipped R2.  Three notable ones:

  1. SCOM Management Pack - this is a combo that includes what was the QoE monitoring MP which is a must for any serious deployment with Voice/Video so you can proactively monitor media quality.  Get it here: http://www.microsoft.com/downloads/details.aspx?FamilyID=0FCA3752-76D4-42F3-9241-A663E40C1E2C&displaylang=en
  2. BPA - RTCBPA itself doesn't change but the XML ruleset has been updated for R2.  Get RTCBPA here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=1b90993c-072a-4c84-b385-b76d23b2f27c and then have it check for updates.
  3. Capacity Planning Tool - remember this from LCS 2005?  It's back for R2!  It does all the R2 workloads but not web conferencing or Group Chat.  Get it here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=f8cbddd6-7608-4bbe-9246-16e96c62bef4
