WooCommerce FedEx Shipping 4.8.1

* FedEx Changelog *

2026-09-16 - version 4.8.1
- 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.

2026-09-03 - version 4.8.0
- Add - FedEx Freight (LTL) live rates via the new FedEx Freight platform (api.ltl.tech), which the FedEx Freight spinoff moved LTL rating onto.
- Add - Separate FedEx Freight API credentials, OAuth, and an independent production/sandbox environment toggle for the FedEx Freight platform.
- Tweak - FedEx Freight (LTL) rates now require separate FedEx Freight API credentials from developer.fedexfreight.com. Stores that rated LTL before the spinoff will not receive LTL rates until those credentials are entered.
- Fix - A rate response containing no rates is now remembered for ten minutes instead of a week, so a temporary empty result from FedEx no longer suppresses rates for that destination for days.
- Fix - Stores that have not entered their FedEx API credentials no longer write authentication errors to the log on every request.
- Fix - Saving new API credentials now clears the cached token and reports whether they authenticated; both checks were silently skipped before. […]

2026-08-05 - version 4.7.0
- Add - FEDEX_INTERNATIONAL_DEFERRED_FREIGHT service code and freight mapping, so stores with freight enabled see the service named in the cart instead of with a blank label.
- Fix - Freight-qualified shipments to international destinations no longer return a 400 error; routed to standard rate endpoint which can return INTERNATIONAL_PRIORITY_FREIGHT and INTERNATIONAL_ECONOMY_FREIGHT for heavy international packages.
- Fix - StateOrProvinceCode is no longer sent for non-US/CA/PR destinations.
- Fix - Hyphens stripped from recipient postal codes for international format compatibility.
- Tweak - Removed the legacy SOAP (Web Services) API. All stores now use the REST API; any store still configured for SOAP is automatically switched to REST.

2026-07-27 - version 4.6.2
- Tweak - WooCommerce 11.0 Compatibility.

2026-07-20 - version 4.6.1
- Fix - Liftgate special services are now only added to Freight (FDXF) rate requests, preventing SERVICE.PACKAGECOMBINATION.INVALID errors on non-Freight (Express, Ground, and SmartPost) requests.
- Fix - Retry transient transport failures (cURL timeouts, connection resets) in the FedEx REST API client before returning an empty rate list.

2026-06-30 - version 4.6.0
- Add - New filters woocommerce_shipping_fedex_skip_item_box_packing and woocommerce_shipping_fedex_packages to let developers customise box packing and packages. […]
