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.
Martin is back on beta
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.
