2026-07-27 – version 5.6.1
* Fix – Media Mail, Library Mail and other services no longer disappear from checkout when their enabled setting was stored by anything other than the settings screen, such as WP-CLI or a site migration.
* Tweak – Log a debug line naming the service whenever a rate is skipped because it is disabled in the settings.
* Tweak – WooCommerce 11.0 Compatibility.
2026-06-30 – version 5.6.0
* Add – Optional shipping insurance and signature confirmation, offered to customers as selectable rates at checkout and priced by USPS.
* Add – New filters woocommerce_shipping_usps_skip_item_box_packing and woocommerce_shipping_usps_package_requests to let developers customise box packing and package requests.
* Fix – Service commitment delivery time shown in USPS rate labels is now scoped to the selected rate, fixing inconsistent visibility when a per-rate woocommerce_shipping_usps_should_show_service_commitment filter is used.
