BREAKING CHANGE (maybe) Well as long as our customers use public API this should not be a breaking change, but we have changed import structure as well as internal names, so it could be breaking. import: angular2/annotations => angular2/metadata Classes: *Annotations => *Metadata renderer.DirectiveMetadata => renderer.RendererDirectiveMetadata renderer.ElementBinder => renderer.RendererElementBinder impl.Directive => impl.DirectiveMetadata impl.Component => impl.ComponentMetadata impl.View => impl.ViewMetadata Closes #3660
