In addition to the normal bots, it appears that v4.2.7 added Piece Notation (English | Localized | Figurine) in Settings > Game.
Thank you chess.com, that's a very nice addition to the app!
Chess bots on app playing way above their reported level.


100% agree. The bots on the Android app started playing at a tremendous level, the same bots on the online version play as their normal self.
When I look at the Play Store, the lastest update is Feb 26.
Yes Feb 26 is v4.2.7 with the normal bots that just today became available for production Update today. (It has been available in Beta for the last few days.)
