Breaking Changes

animations

• Deprecated matchesElement method has been removed from AnimationDriver as it is unused.

core

• async has been removed, use waitForAsync instead.

http

• By default we now prevent caching of HTTP requests that require authorization . To opt-out from this behaviour use the includeRequestsWithAuthHeaders option in withHttpTransferCache.

  Example:

  withHttpTransferCache({
    includeRequestsWithAuthHeaders: true,
  })

platform-browser

• Deprecated StateKey, TransferState and makeStateKey have been removed from @angular/platform-browser, use the same APIs from @angular/core.

Deprecations

common

• getCurrencySymbol, getLocaleCurrencyCode, getLocaleCurrencyName, getLocaleCurrencySymbol, getLocaleDateFormat, getLocaleDateTimeFormat, getLocaleDayNames, getLocaleDayPeriods, getLocaleDirection, getLocaleEraNames, getLocaleExtraDayPeriodRules, getLocaleExtraDayPeriods, getLocaleFirstDayOfWeek, getLocaleId, getLocaleMonthNames, getLocaleNumberFormat, getLocaleNumberSymbol, getLocalePluralCase, getLocaleTimeFormat, getLocaleWeekEndRange, getNumberOfCurrencyDigits

http

• HttpClientModule, HttpClientXsrfModule and HttpClientJsonpModule

  As mentionned, those modules can be replaced by provider function only.

service-worker

Commit	Description
	avoid running CDs on controllerchange (#54222)

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.

Breaking Changes

router

• Providers available to the routed components always
  come from the injector heirarchy of the routes and never inherit from
  the RouterOutlet. This means that providers available only to the
  component that defines the RouterOutlet will no longer be available to
  route components in any circumstances. This was already the case
  whenever routes defined providers, either through lazy loading an
  NgModule or through explicit providers on the route config.

Commit	Description

	RouterLinkActive will always remove active classes when links are not active (#54982)

Breaking Changes

compiler-cli

• • Angular no longer supports TypeScript versions older than 5.4.

core

• ComponentFixture.whenStable now matches the
  ApplicationRef.isStable observable. Prior to this change, stability
  of the fixture did not include everything that was considered in
  ApplicationRef. whenStable of the fixture will now include unfinished
  router navigations and unfinished HttpClient requests. This will cause
  tests that await the whenStable promise to time out when there are
  incomplete requests. To fix this, remove the whenStable,
  instead wait for another condition, or ensure HttpTestingController
  mocks responses for all requests. Try adding HttpTestingController.verify()
  before your await fixture.whenStable to identify the open requests.
  Also, make sure your tests wait for the stability promise. We found many
  examples of tests that did not, meaning the expectations did not execute
  within the test body.

  In addition, ComponentFixture.isStable would synchronously switch to
  true in some scenarios but will now always be asynchronous.

router

• When a a guard returns a UrlTree as a redirect, the
  redirecting navigation will now use replaceUrl if the initial
  navigation was also using the replaceUrl option. If this is not
  desirable, the redirect can configure new NavigationBehaviorOptions by
  returning a RedirectCommand with the desired options instead of UrlTree.
