These aren't clear or verbose at this point, but I wanted to get the info out to anyone who wants it:
TADDM 7.2 and CCMDB 7.2 are out now, and they seem to work just great.
The TADDM 188.8.131.52 -> 7.2 upgrade works amazingly well, tho it takes several hours if you have lots of data
Java 1.6_17 (the latest as of a couple of weeks ago) JRE doesn't work with the TADDM GUI. You need to use an older version (1.6_07 works like a champ).
New in TADDM 7.2 is an "explore" feature in a topology view. This lets you add additional relationships to a view. So you can right-click a machine and select "Explore", then select what relationships you want displayed, then you can select which other objects that are associated via those relationships will be displayed. Kinda nifty.
CCMDB 7.2 has a new CI topology view. This is a nice feature so you don't have to launch over to TADDM just to see topology info.
In CCMDB 7.2, the "Admin" workstation is no longer limited to just Windows - Linux is supported (so you can run the CCMDB Launchpad from a Linux machine).
