Hub Platform Update - Procedure for updating existing apps?

I thought I recalled that we need to do something to bring existing apps up to the latest release level (e.g., Apps written in RM) after installing the hub platform update . . . would you please point me to that guidance (if unchanged) or provide a brief message (if there have been changes)?

Thank you!

Everything should just work as is. No need for any special steps.

At least, that's the plan and what's been tested....

Awesome. Thank you!
