Breaking changes

• Always load static files from context root (#13795)
  Commit · Pull request · Issue

  Static resources are always served from /VAADIN in the context path. If you're not using Spring and use a non-root mapping for your servlet (not a /*), then you need to separately map a Vaadin servlet to /VAADIN/* like shown below:

  @WebServlet(asyncSupported = true, urlPatterns = { "/admin/*", "/VAADIN/*" })
  public class ViewTestServlet extends VaadinServlet {
  }

  For multiple servlet mappings, this makes the application load a static files only once from /VAADIN and not from both /myapp/VAADIN and /admin/VAADIN.

New features

• Support listening to browser unsubscribe in endpoint methods (#13731)
  Commit · Pull request

  Adds support for EndpointSubscription as an endpoint return value An endpoint subscription is the same as a Flux but in addition supports an unsubscribe event handler, triggered when the client closes the subscription (not when the flux completes or errors)

• Clean up flux subscription on browser disconnect (#13729)
  Commit · Pull request

• Avoid potential slow Set#removeAll call in HierarchicalCommunicator (#13746)
  Commit · Pull request · Issue

• Improve message sender / handler robustness in resync scenarios (#13733)
  Commit · Pull request · Issue

  Process re-sync messages via normal message queue and use semaphore to protect re-sync process (i.e. do not allow other messages while performing re-sync). This PR is adopted from similar fixes for Vaadin 8. vaadin/framework#11791 vaadin/framework#12043 vaadin/framework#12178 This also changes the method forceMessageHandling in a way that the desire to resynchronise is registered before calling endRequest. If this is not done, endRequest may end up sending out a request itself and that then causes the re-sync request to fail because a request is already in flight. This ends up throwing an IllegalStateException at com/vaadin/client/communication/RequestResponseTracker.java.

• Always get url mapping using helpers when using Spring Boot (#13791)
  Commit · Pull request · Issue

  The properties in application.properties use a relaxed mapping strategy in Spring Boot so all variants of "url-mapping","urlmapping","urlMapping" are mapped to the same value in VaadinConfigurationProperties.

• Devmode popup will show Hilla instead of Vaadin in Hilla applications (#13725)
