- (test only) -
TestBednow provides a fakePlatformLocationimplementation that supports the Navigation API. This may break some tests, though we have not observed any failures internally. You can revert to the old default forTestBedby providing theMockPlatformLocationfrom@angular/common/testingin your providers:{provide: PlatformLocation, useClass: MockPlatformLocation} ngComponentOutletContentis now of typeNode[][] | undefinedinstead ofany[][] | undefined.- NgModuleFactory has been removed, use NgModule instead.

The server-side bootstrapping process has been changed to eliminate the reliance on a global platform injector.
Before:
const bootstrap = () => bootstrapApplication(AppComponent, config);After:
const bootstrap = (context: BootstrapContext) => bootstrapApplication(AppComponent, config, context);A schematic is provided to automatically update
main.server.tsfiles to pass theBootstrapContextto thebootstrapApplicationcall.In addition,
getPlatform()anddestroyPlatform()will now returnnulland be a no-op respectively when running in a server environment. -
Using a combination of
provideZoneChangeDetectionwhile 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. -
- TypeScript versions less than 5.9 are no longer supported.
-
(test only) - Using
provideZoneChangeDetectionin the TestBed providers would previously preventTestBedfrom rethrowing errors as it should. Errors in the test will now be rethrown, regardless of the usage ofprovideZoneChangeDetection. Tests should be adjusted to prevent or account for these errors. As in previous major versions, this behavior can be disabled withrethrowApplicationErrors: falseinconfigureTestingModuleas a last resort. -
ignoreChangesOutsideZoneis no longer available as an option for configuring ZoneJS change detection behavior. -
Angular no longer provides a change detection scheduler for ZoneJS-based change detection by default. Add
provideZoneChangeDetectionto the providers of yourbootstrapApplicationfunction or yourAppModule(if usingbootstrapModule). This provider addition will be covered by an automated migration. -
moduleIdwas removed fromComponentmetadata. -
The
interpolationoption on Components has been removed. Only the default{{ ... }}is now supported.
elements
-
Fix signal input getter behavior in custom elements.
Before this change, signal inputs in custom elements required function calls to access their values (
elementRef.newInput()), while decorator inputs were accessed directly (elementRef.oldInput). This inconsistency caused confusion and typing difficulties.The getter behavior has been standardized so signal inputs can now be accessed directly, matching the behavior of decorator inputs:
Before:
- Decorator Input:
elementRef.oldInput - Signal Input:
elementRef.newInput()
After:
- Decorator Input:
elementRef.oldInput - Signal Input:
elementRef.newInput
- Decorator Input:
forms
- This new directive will conflict with existing FormArray directives or formArray inputs on the same element.
platform-browser
- The deprecated
ApplicationConfigexport from@angular/platform-browserhas been removed. Please importApplicationConfigfrom@angular/coreinstead.
router
lastSuccessfulNavigationis now a signal and needs to be invoked- Router navigations may take several additional microtasks to complete. Tests have been found to often be highly dependent on the exact timing of navigation completions with respect to the microtask queue. The most common fix for tests is to ensure all navigations have been completed before making assertions. On rare occasions, this can also affect production applications. This can be caused by multiple subscriptions to router state throughout the application, both of which trigger navigations that happened to not conflict with the previous timing.
