I don't understand: Feb 25 announcement or release?

I feel like I've been waiting this for so long and I don't even know what it is! I'm expecting 21 mechanics/items implemented into the game. Maybe 10 items and 11 new mechanics (bodyhair and Private Practice- You can add health insurance, diseases, plastic surgery, pharmaceuticals and optometry to your collection).

If they made us wait so much it is because is huge!
