Snapchat will let you ditch your old username for a new one starting today. So, if you've been dying to rebrand on the social app, you can do that now. But there are a few conditions. You can only change your username once a year, and you won't get the old one back. Old usernames won't be available to anyone, which iMore pointed out is a shame for names taken by username squatters.
