It looks like the official Mastodon app has been updated to use the terminology of the experimental web interface.
⭐️ Favourites are now called ❤️ Likes.
Trending is now called Explore (which is what it was called originally 😄 ).
This hasn't been rolled out to the release version of the web interface yet, so you probably won't see these changes on your server's website yet.

@FediTips Seems fine (prefer a star for 'like' tho 🤷♀️).
It's good compared to some of the web interface layout updates, which have diminished visual breaks between elements. The updated web UX is slower and harder to navigate, ime. It looks a bit chaotic.
