I might be blind, but I don't see any information on the faction selection screen regarding the new abilities/units for each faction. The only way that I know about them is through the beta notes.
Also, you might want to update the tutorial. It still talks of researching mining to be able to mine ore.
All in all, this is another gigantic step forward. If you can polish up city management and tighten up research, this game will be a 90+ on Metacritic, no doubt.
