I upgraded my v 12 to 13 on my DEV box. Both versions are available for use (thank goodness). I just noticed that the Flag category in the Library is gone in v13. When v13 was installed, it apparently copied all of my settings from v12 (nice touch thank you!) so I can close v13 and open v12 and use it. I captured a pic that shows both versions of my library. And yes, I have a lot of pics in my library. So where did the Flags classification go?
