4.0.3

Imports: added use craft\helpers\FileHelper;
New properties: public bool $clearEmbedsField = false; and public bool $reprocess = false;
Options: added clearEmbedsField and reprocess to options()
CKEditor config: handle null/unset config by falling back to the first available config (throws if none), and save via the ckeConfigs service
Migration logic: backup raw copy-field content per entry (migrates legacy backup filenames), skip entries if backup exists unless reprocess=true, and only clear the embeds field if clearEmbedsField is true
