• Extract addon files to frontend/generated/jar-resources instead of a fake npm package (#14979)

New features

• Allow excluding URLs from being handled by a root mapped Vaadin Spring servlet

  This makes it possible to make services like swagger work correctly even when Vaadin is mapped to the context root.

• Adapt to a new auto configuration in Spring Boot
  Commit · Pull request · Issue

  Spring Boot introduced a new location for auto configuration entries in spring boot 2.7.0. The new location is META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports. This has until spring boot 3.0.0-M5 worked in parallel with the spring.factories configuration. The spring.factories support was removed in spring boot 3.0.0-M5 so this move has to be done now in order for the auto configuration to be picked up. Picked to master from #14629

Fixes

• Synchronize pwa handler on map (#14838)

  Synchronize pwa handler on the requestHandlerMap instead of locking the session. Locking and unlocking session may fire a push event that might make the server client sync faulty. touches #14797

• Defer location and query tracking
  Commit · Pull request · Issue

  Track of location and query string after response from server happens too early when handling server side navigation, because history.pushState is executed within a setTimeout. This change defers the tracking to the next event loop cycle in order to get the correct values.

• Redirect if refresh token is in push response also
  Commit · Pull request · Issue

• Ignore nonexistent nodes during resync
  Commit · Pull request · Issues 14232, 14470

  Ignore changes for nodes that are not available in the tree when a resync is underway. This will get the page to a working condition after a resync as all changes for existing nodes are executed.

• Attach polymer binding callback to a promise that always resolves
  Commit · Pull request · Issue

  Polymer binding callback was attached to the promise returned by customElements.whenDefined, but this promise may never complete if the input element is not a custom element, causing memory leaks on browser because of element capture. This change introduces a new promise that completes either when whenDefined is fulfilled or after a fixed timeout, allowing the garbage collector to clean resources.

• Write version.json from the currently constructed package.json
  Commit · Pull request

  The earlier logic was like 1. Read package.json 2. Modify package.json in memory 3. Generate version.json based on package.json file 4. Write modified package.json to file Where step 3 ignored what was done in step 2

  As the default download root might be different depending on the used system we should not use a hardcoded default if user has not given a download root.
