is there a changelog anywhere that tells us what's in these updates?
New Features

We had some problems with the update.
We where so sick en tired of it, searching the web for sollutions time after time. Fixing one problem, creating a new one.
We decided to completely setup our server again, OS + Plesk.
Then we updated to 8.4 and without any problems (so far).
I wouldn't recommend updating unless you are/where planning to setup your server again from cratch.
