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.
