What is the minimum version of AE I need to have installed?
I ask because I have AE version 13.7.2 and do not see the 13.8.1 patch when running the RemoteUpdateManager.
AE 13.8.x (also called CC 2015.3) is not an update to CC 2015. It is a whole new version. (I don't know why it wasn't called CC 2016...this makes it much more confusing!)
So, it is a new version that can be installed alongside version 13.7.2. Just make sure the Creative Cloud app doesn't remove your old version when you install it as it defaults to do. See this page for some details.
Thanks for the quick reply!
No problem! Be aware that there are new versions of Photoshop, Media Encoder, Premiere, Audition, etc. too. See this page for a quick overview (and some more in-depth links) to what's new across the apps in this release.
