Breaking Changes

common

• ngComponentOutletContent is now of type Node[][] | undefined instead of any[][] | undefined.

core

• Using a combination of provideZoneChangeDetection
  while also removing ZoneJS polyfills will no longer result in the
  internal scheduler being disabled. All Angular applications now
  consistenly use the same scheduler, and those with the Zone change detection
  provider include additional automatic scheduling behaviors based on
  NgZone stabilization.
• Angular no longer provides a change detection scheduler
  for ZoneJS-based change detection by default. Add
  provideZoneChangeDetection to the providers of your
  bootstrapApplication function or your AppModule (if using
  bootstrapModule). This provider addition will be covered by an
  automated migration.
• moduleId was removed from Component metadata.
• The interpolation option on Components has been removed. Only the default {{ ... }} is now supported.
