Upgrading 4.0.1 to 4.0.2

[FunkyPenguin]

This is just a quick one, to see if the MySQL database requires a schema update the same as going from 3 to 4?

I just upgraded yesterday, and saw that it went through a schema update which surprised me as I thought the schema was the same. Am I wrong in my assumption, and if not could someone tell me if I'm worrying over nothing? I just want to make sure that my ZCS is working and isn't about to kick me again

Yes there is a schema change. Most of the changes were for the IMAP performance improvements(column changes, index changes, etc).
