Yes...a few changes with this upgrade:
Round avatars (seems like that is the style now)
Likes are now reactions (can choose a few different reactions)
Bookmarks have changed (how to bookmark and viewing bookmarks) but all previous bookmarks are still there
Push notifications have been enabled...
"Nextbase Tiffany" used to be very active here responding to owners concerns. Last month Tiffany asked to change her member name to "NextbaseSupport" and the last message posted from that account was Dec 21st. May be something to consider as well.
