WooCommerce version: 11.1.2

WordPress version: 5.0

WooCommerce version: 6.0.0

5.0.0 – 29 September, 2026

Breaking – Removed unused classes, functions and filters (e.g. walley_update_cart_args, walley_update_fees_args, walley_update_metadata_args, coc_order_refund_args, cco_customer_country). Custom code relying on these must be updated.
Enhancement – Added support for orders, products, shipping and fees with a value of 0, for example free products, free shipping or a 100% discount coupon.

4.5.6 – 15 September, 2026

Fix – Fixed an issue where a purchase could be completed in Walley without an order being created in WooCommerce.
Fix – Fixed deprecation warnings related to dynamic properties.

4.5.5 – 31 August, 2026

Fix – Fixed an intermittent issue where customers could be unable to complete checkout when a Walley order update was temporarily locked by a simultaneous request (HTTP 423 Resource_Locked). The request is now retried automatically after a short delay.
Fix – Fixed a bug where customers saw a "syntax error" at checkout instead of the actual reason their order couldn't be completed.
Fix – Fixed an issue where a customer could in some cases be unable to complete their purchase the first time they reached the Walley checkout, due to a missing public token on the initial page load.
Fix – Fixed an issue where the Walley Checkout could fail to load or update if the customer's checkout session had expired.
Fix – Previously, some checkout failures resulted in an empty error message, or in a technical error code. Customers are now told when their checkout session has expired, and error messages are always shown as plain text.
