Drupal 11.0.0 is a free software package that allows an individual or a community of users to easily publish, manage and organize a wide variety of content on a website. The Ajax system now validates URLs before making an Ajax request. Existing code which uses the Drupal Ajax API in any of the standard ways should continue to work after this update. In the event you have unusual Ajax code which does not work with Drupal 11.0.0, you can have your code manually validate the URL in one of two ways.
