Update Software

It would really be nice if Waters would clearly communicate Empower (E3) versions; service release; Feature release; Hotfix; DB versions; in one place. I was chasing this last week and it is opaque to piece it together from release notes! <Rant> Why do I need a decoder ring to find out what version we are on? E3 FR4 SR3 b3471 seems to be correct for us. This is after a long list of Service Packs and Hotfixes. 

They just had some support notes about something called Empower 3.6.0. Is that E4 or is this a new version using a new standard notation?

Wouldn't it be nice to have a clear list of upgrades we could plan for? Some are dead ends ~ require full fresh install!  

• Is a release recommended or urgent? 
• How many other sites are running it successfully? 
• What are other sites running or planning to upgrade to?

I am sure someone at Waters has done the work to document all of the valid software updates and possible paths. Is this shared somewhere?
