Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
The new version does not support a few configurations that we had before, such as pattern. But this is not a problem since the new version does not need such configuration at all. Upgrade is straightforward simply change CKeditor4 to CKeditor5 and the new configuration will be applied automatically.
CKEditor Mentions now uses official CKeditor plugin, and we've implemented new plugin system to make it more configurable. By default we support user and node as mentionable entities.
