+# 18.0.0-next.5 (2024-04-17)
+## 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.
