Breaking Changes

common

• The deprecated isPlatformWorkerUi and isPlatformWorkerApp have been removed without replacement, as they serve no purpose since the removal of the WebWorker platform. ### compiler
• Angular only supports writable expressions inside of two-way bindings. ### core
• Angular will ensure change detection runs, even when the state update originates from outside the zone, tests may observe additional rounds of change detection compared to the previous behavior.

This change will be more likely to impact existing unit tests. This should usually be seen as more correct and the test should be updated, but in cases where it is too much effort to debug, the test can revert to the old behavior by adding provideZoneChangeDetection({schedulingMode: NgZoneSchedulingMode.NgZoneOnly}) to the TestBed providers.

Similarly, applications which may want to update state outside the zone and not trigger change detection can add provideZoneChangeDetection({schedulingMode: NgZoneSchedulingMode.NgZoneOnly}) to the providers in bootstrapApplication or add schedulingMode: NgZoneSchedulingMode.NgZoneOnly to the BootstrapOptions of bootstrapModule. - Testability methods increasePendingRequestCount, decreasePendingRequestCount and getPendingRequestCount have been removed. This information is tracked with zones.
