It’s in our backlog to include an update-checking mechanism in each plugin. Unfortunately it hasn’t been looked at yet.

That’s unfortunate. 

I’m speculating that many (most…?) customers would consider that a basic and expected functionality at release. 

Maybe in the interim you could just email update notices to registered customers that have opted-in for emails from Eventide.

That would suffice until a “Check for updates’ menu item could be added to each plug-in…

Just my 2cents…
