I'm looking to provide a short list of notable impact-items for clients that make substantial jumps in CUCM versions. Aside from sending them a barrage of release notes or even the "new and changed information" Cisco docs, anyone have a good bullet list of key impact items? I'm thinking just those things that may affect their day-2 MACD or end-user experience (e.g., firmware x introduces feature y, etc. etc.).
I know, it's a tall task - but I figured I'd throw it out there.
