* Fix – Tracking meta box scripts are now enqueued on admin_enqueue_scripts, so the Delete button and AJAX save work reliably on all environments.

* Fix – Custom boxes removed from the Box Sizes table now persist after saving.
* Fix – Box Sizes fields no longer block saving the settings when the box packing method is not selected.
* Fix – "Additional Options" setting label could not be translated; it now uses the plugin text domain.

* Tweak – The FedEx Freight credentials warning is now a standard WooCommerce notice plus an Inbox note, it names the affected shipping zones, and it returns after 30 days if the credentials are still missing instead of staying dismissed forever. The `fedex_dismiss_freight_credentials_notice` AJAX action is deprecated and will be removed in 4.9.0; existing dismissals are migrated automatically.

* Fix – Security update.

* Update WC version to 11.1
