Updating Ionic2 from alpha to beta

Hi everyone, not sure if someone asked already, but can someone tell me how to regularly update my project which is Ionic 2.0.0-alpha.54 to the newest 2.0.0-beta.2? I see there is no more ionic-framework but ionic-angular in beta version and I’m not sure how should I update my project, if it’s even possible. Thanks in advance.
