For the record, since there seems to be some confusion, the Easter content isn't being introduced in this new update. 505 is just taking the opportunity to remind you that Easter is approaching, so you'll be seeing the Easter content, which has been on Mobile since Easter of last year.
In addition to that reminder, 505 is also informing you of a new update that'll be available soon, which is predominately unrelated to Easter, and contains several bug fixes.
