16.0.0-next.1 (2023-03-01)

Breaking Changes

compiler

• • TypeScript 4.8 is no longer supported.

core

• Node.js v14 support has been removed

  Node.js v14 is planned to be End-of-Life on 2023-04-30. Angular will stop supporting Node.js v14 in Angular v16. Angular v16 will continue to officially support Node.js versions v16 and v18.

router

• Tests which mock ActivatedRoute instances may need to be adjusted
  because Router.createUrlTree now does the right thing in more
  scenarios. This means that tests with invalid/incomplete ActivatedRoute mocks
  may behave differently than before. Additionally, tests may now navigate
  to a real URL where before they would navigate to the root. Ensure that
  tests provide expected routes to match.
  There is rarely production impact, but it has been found that relative
  navigations when using an ActivatedRoute that does not appear in the
  current router state were effectively ignored in the past. By creating
  the correct URLs, this sometimes resulted in different navigation
  behavior in the application. Most often, this happens when attempting to
  create a navigation that only updates query params using an empty
  command array, for example router.navigate([], {relativeTo: route, queryParams: newQueryParams}). In this case, the relativeTo property
  should be removed.
