• package.json needs to be updated (we intentionally bump the version manually each time for now to have control over breaking changes that require blueprints update)
• replace import ... from 'angular2/angular2' with ... from 'angular2/core' (this might still change in the future, see update typings entry point in npm's package.json angular#5539, but for now let's switch to core)
• the only exception to the above is bootstrap which should come from import {bootstrap} from 'angular2/platform/browser'

that should be it...

cc: @wardbell for documentation update since that will be affected in similar way
