Breaking Changes

core

• The second arguement of appRef.bootstrap does not accept any anymore. Make sure the element you pass is not nullable.
• • TypeScript versions older than 6.0 are no longer supported.
• ComponentFactoryResolver and ComponentFactory are no longer available. Pass the component class directly to APIs that previously required a factory, such as ViewContainerRef.createComponent or use the standalone createComponentFunction.

platform-browser

• This removes styles when they appear to no longer be used by an associated host. However other DOM on the page may still be affected by those styles if not leveraging ViewEncapsulation.Emulated or if those styles are used by elements outside of Angular, potentially causing other DOM to appear unstyled.

router

• The currentSnapshot parameter in CanMatchFn and the canMatch method of the CanMatch interface is now required. While this was already the behavior of the Router at runtime, existing class implementations of CanMatch must now include the third argument to satisfy the interface.
