Breaking Changes

router

• Previously null and undefined inputs for routerLink were
  equaivalent to empty string and there was no way to disable the link's
  navigation.
  In addition, the href is changed from a property HostBinding() to an
  attribute binding (HostBinding('attr.href')). The effect of this
  change is that DebugElement.properties['href'] will now return the
  href value returned by the native element which will be the full URL
  rather than the internal value of the RouterLink href property.
