Breaking Changes

common

• the NgSwitch directive now defaults to the === equality operator, migrating from the previously used ==. NgSwitch expressions and / or individual condition values need adjusting to this stricter equality check. The added warning message should help pinpointing NgSwitch usages where adjustements are needed. ### core
• The mutate method was removed from the WritableSignal interface and completely dropped from the public API surface. As an alternative please use the update method and make immutable changes to the object.

Example before:

  items.mutate(itemsArray => itemsArray.push(newItem));

Example after:

  items.update(itemsArray => [itemsArray, …newItem]);

platform-browser

• The withNoDomReuse() function was removed from the public API. If you need to disable hydration, you can exclude the provideClientHydration() call from provider list in your application (which would disable hydration features for the entire application) or use ngSkipHydration attribute to disable hydration for particular components. See this guide for additional information: https://angular.io/guide/hydration#how-to-skip-hydration-for-particular-components. ### router
• Routes with loadComponent would incorrectly cause child routes to inherit their data by default. The default paramsInheritanceStrategy is emptyOnly. If parent data should be inherited in child routes, this should be manually set to always.
