Any issues upgrading from 3.7.0 beta to 3.7.0 final?

I want to update but I’m scared

I didn’t notice any, though it was only my testing server. But a work server went ok from 3.6.4 to 3.7.0.

Any special procedure to upgrade or just run the setup program? (this is on Windows Server)

Yep. Just run the setup.
