Is there anything else we should know?

Maybe there are other controls not working with ChangeDetectionStrategy.OnPush

I still see this bug in beta.2 when using reactive forms.

I'm seeing the same, beta.2/angular 4.0.0 reactive forms with ChangeDetectionStrategy.OnPush still exhibits this behaviour. Is there a temporary quickfix?
