Breaking Changes

common

• Using the Y formatter (week-numbering year) without also including w (week number) is now detected as suspicious date pattern, as y is typically intended.
• AsyncPipe now directly catches unhandled errors in subscriptions and promises and reports them to the application's ErrorHandler. For Zone-based applications, these errors would have been caught by ZoneJS and reported to ErrorHandler so the result is generally the same. The change to the exact mechanism for reporting can result in differences in test environments that will require test updates.

compiler

• 'in' in an expression now refers to the operator

• void in an expression now refers to the operator

  Previously an expression in the template like {{void}} referred to a property on the component class. After this change it now refers to the void operator, which would make the above example invalid. If you have existing expressions that need to refer to a property named void, change the expression to use this.void instead: {{this.void}}.

core

• TypeScript versions less than 5.8 are no longer supported.

• the TestBed.flushEffects() was removed - use the TestBed.tick() instead.

• provideExperimentalCheckNoChangesForDebug has several breaking changes:

  • It is renamed to provideCheckNoChangesConfig
  • The behavior applies to all checkNoChanges runs
  • The useNgZoneOnStable option is removed. This wasn't found to be generally more useful than interval

• provideExperimentalZonelessChangeDetection is renamed to provideZonelessChangeDetection as it is now "Developer Preview" rather than "Experimental".

• • InjectFlags has been removed.
  • inject no longer accepts InjectFlags.
  • Injector.get no longer accepts InjectFlags.
  • EnvironmentInjector.get no longer accepts InjectFlags.
  • TestBed.get no longer accepts InjectFlags.
  • TestBed.inject no longer accepts InjectFlags.
• • TestBed.get has been removed. Use TestBed.inject instead.

• afterRender was renamed to afterEveryRender.

• • Angular no longer supports Node.js v18.
  • Node.js versions 22.0 to 22.10 are also no longer supported.

  Before upgrading to Angular v20, ensure the Node.js version is at least 20.11.1. For the full list of supported versions, visit: https://angular.dev/reference/versions

• PendingTasks.run no longer returns the result of the
