Druxt's Drupal module carries a list of twelve JSON:API resources it answers for. It's been the same twelve since 2021, hardcoded in a PHP array, and changing it has meant carrying a patch.
1.3.0, tagged today, makes that list yours. The twelve stay exactly as they are, so nothing a site exposes changes when it updates. What is new is being able to choose, and the first thing I would choose is the one my frontend has always had to guess at: the toolbar an administrator configured for a text format.
A CORS default ships in the same release. If you keep a proxy rule in front of your frontend so that authenticated calls succeed, this is the release where you delete it.
