0.23 has a new encounter with Amber and Anya. During this encounter you get a chance to question Amber about some things you learned. You also get a chance at one of three dates: Mark, Anya or Amber. 

You learn more about Amber and also set up an event for the Saturday update! Some things change based on how much you've learned about Lisa and a few things are only available if you're a first time player or restart due to me expanding a bit on day 1 of the game. You'd only miss out on one or two questions you can ask her so if you don't wish to replay when 0.23 comes out don't feel pressured to do so!
