Introduced in version: 
9.4.4
Description: 

Previously, plugin settings for all CKEditor 4 plugins were stored in the editor configuration. This included disabled plugins. As a result, disabled plugins could be incorrectly re-enabled when upgrading to CKEditor 5.

To keep the editor configuration in a consistent state, plugin settings are now only stored for CKEditor plugins that are enabled. Drupal 9.4.4 introduces an entity presave hook and update hook which will delete settings for all disabled plugins. This may result in stored configuration diffs for editor configuration entities following updates to Drupal 9.4.4.

Sites using CKEditor should update to at least Drupal 9.4.4 prior to updating to Drupal 10 so that their plugin configuration is handled correctly.
