* Fix: Avoid issue where REST API product metadata responses could be objectified
* Update: Use WooCommerce enums where supported

* Fix – Prevent an error that replaced the shipping section of the block checkout with an error message when returning from the multiple addresses selection screen.
* Fix – Prevent checkout errors when shipping method, product, or delivery date information is temporarily incomplete.
* Fix – Keep the note, delivery date, and gift option for every shipment when they are changed one after another on the block checkout. Previously the values of the other shipments could be lost.
* Fix – Update the tax totals on the block checkout after multiple shipping addresses are set. The update request was not sent.
* Fix – Show why a shipment cannot be quoted on block checkout; the reason was calculated but never displayed.
* Fix – Include the shipping phone in the customer's default address so shipping can be calculated when the phone field is set to required.
* Fix – Persist every field the store collects when saving the default address, so a changed shipping phone is no longer ignored.
* Fix – Keep the customer's own shipping phone intact when checking out against a saved address book entry.
* Fix – Stop counting the phone toward the number of filled fields that decides whether a checkout address is saved to the address book.
* Fix – Stop offering shipping rates for a shipment whose address the store cannot ship to, instead of quoting a price the order would then be refused for.
* Fix – Stop emitting a PHP warning on the order screen when a shipment address predates a field the store now collects.
* Tweak – Name the missing fields when a saved shipping address is incomplete, instead of reporting that no address is assigned.
* Tweak – Derive the shipping address fields from the store's own settings everywhere, so a field the merchant adds or makes required is handled consistently.
* Tweak – Block checkout: keep the per-shipment shipping method selectors grouped together, with the shipment cards and the "Set multiple addresses" button shown directly below them.
* Fix – Use the same order ownership check as WooCommerce core.

* Fix – Use the plugin text domain for the "Premium Support" link so the string is translatable.
* Fix – Appended shipping rules from a CSV import now always sort after the rules a product already has, and matching no longer depends on database row order when rules are tied.
* Fix – The shipping rate cache is refreshed after a CSV import, so carts quote the imported rates on the next request.

* Add – Royal Mail and Parcelforce rates effective October 5, 2026.
* Fix – Shipping rates are no longer removed by a fatal error, and no longer silently disappear, when third-party code returns invalid data from the rate bands or boxes filters. The invalid value is now ignored and a notice is logged when debugging is enabled.

* Fix – Declare the block checkout script dependencies so the address validation notice cannot load before the scripts it relies on.
* Tweak – React 19 Compatibility.
* Tweak – Use the plugin's own text domain for the "Choose a country…" placeholder on the settings screen so it can be translated with the plugin's language pack.
