18.0.0-next.2 (2024-03-28)

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.
