Add API for automatic main menu Commit · Pull request · Issue
Adds API to get and control only accessible routes for automatically build routes based on Menu annotated routes. This change is targeting primarily client side menu build with Hilla. Adds RouteRegistry#getRegisteredAccessibleMenuRoutes to get a list of accessible RouteData objects. Method takes in a collection of access control objects which are implementing BeforeEnterListener. Supports NavigationAccessControl and ViewAccessChecker. Adds MenuAccessControl interface to control getRegisteredAccessibleMenuRoutes return value. This change adds first part of control by adding API to enable, disable or automate populating client side main menu with the server side routes. Interface has space for future for more advanced control. Default MenuAccessControl implementation can be customized by implementing it as a Spring bean, or by providing the implementation class via 'menu.access.control' property.

Unwrap router target class in getRouteTarget (#19151) Commit · Pull request · Issue
AbstractNavigationStateRenderer.getRouteTarget filters the active router targets chain comparing collection items class with the route target type. The filter may fail if routes instances are proxy objects created by frameworks like spring, since the class will not match the required one. This cahnge ensures that synthetic and proxy classes are discarded, allowing for more accurate comparison when filtering objects based on their real application class.

Detect Flow PUSH requests as internal framework requests (#19085) Commit · Pull request · Issue

Reorder unhandled imports in CSS bundler (#19021) Commit · Pull request
Currently, CssBundler just replaces @imports with inlined file contents and returns the result. That can be problematic if an unprocessed import, for example to an external URL, comes after an inlined import. Now the unprocessed import comes after a regular CSS rule, which is invalid and ignored by the browser.

Filter hilla and copilot packages better Commit · Pull request · Issue
Filter "com/vaadin/hilla" and "com/vaadin/copilot" packages by default from the class scanner in VaadinServletContextInitializer and include only what is really needed: com.vaadin.copilot.startup and com.vaadin.hilla.startup. This speeds up mostly reload time and also startup time a bit.
