Follows 1.5.44, released earlier the same day, and completes the cart failure handling it started.
Added
- Failed cart actions now tell the shopper what happened. Previously the spinner simply stopped and nothing else appeared, which looked like the click had been ignored. Where WooCommerce provides a specific reason — such as a product being out of stock or a coupon having expired — that message is shown instead of a generic one.
- New
cartpops_generic_error_messagefilter for customising the fallback message shown when no specific reason is available.
