Are they the same thing just renamed? 
ya, it moved to into the context menu of the section navigation. I didn’t even realize the name was changed.
The name was changed because there were two “Refresh” options. One to scan the files. The other to actually go refresh (get new) metadata. It was ambiguous to always specify which one.
Mine still shows Update Library, 1.5.5 QNAP 64bit.
I’m on PMS 1.5.5.3634 but Plex web won’t update beyond 3.2.1
Nevermind.
