Important update information

If you are updating from 10.2.x or earlier and have the CKEditor font module installed, you should consider switching to CKEditor5 Plugin pack for a more up-to-date version of the plugin which is compatible with the CKEditor5 version shipped with Drupal 10.3. If you are updating from Drupal 9, refer to Preparing your site to upgrade to a newer major version for tools you can use to check the Drupal 10 compatibility of modules, themes and sites. Then, upgrade from Drupal 9 to 10. You should also check the Drupal 10.0.0 release notes.
