From now on you need to log in using your new username $1. Your new username is unique to you across every Wikimedia project, and if you are logged in to one project and visit another, your account will carry over with you. The Unified login help page has more information about single-user login, as well as a list of frequently asked questions. If you need to update your email address or to change your password in your preferences, now might be a good time to do so.

To request a different account name, visit Special:GlobalRenameRequest. Thank you for participating on Wikimedia projects.
