Chiming in to show that we're also interested in this option for on premises installations.

While the issues you mentioned were highlighted on the release notes page here: https://docs.connectwise.com/ConnectWise_Control_Documentation/Release_notes/ConnectWise_Control_2019.0_Release_notes

I do agree that in general they need a clear page that highlights changes between builds, I updated our on premise server last week to version 19.0.23234.7027, now I see that version 19.0.23665.7058 is available but I cannot find any release notes for that version.
