Hi, folks! This release is all about adding quality of life improvements and more freedom to customize and support CoCart. You should defiantly checkout the code base on our GitHub repository for more inline documentation added. New filters and action hooks have also been introduced.

We also did some cleaning up. We have a few deprecations in this release. First is that we have removed the legacy API that CoCart started with and removed support for stores running lower than WooCommerce version 4.5.

Two hooks have also been replaced, the cart response can now be filtered further with the addition of two new parameters and fixed an issue where the majority of the product endpoints where not registering since v4.0.

What’s New in CoCart v4.1?

We added a new cart callback that allows you to set the customers billing details. This is late I know but please understand that decoupling is not easy and previous attempts to add customer information to the cart was not sticking until now. Better late than never.

See guide on how to use.

Basic Authentication now accepts a customers billing phone number as their username. Password is still required when authenticating.

And last, added the ability to set the customers billing phone number while adding items to the cart.

Improvements

Various other improvements have also been made affecting support for authentication, custom pricing, calculating totals, product details and more.

Plugin: Should the session not be initialized when called, it now fails safely.
REST API: Authentication now detectable by authorization headers HTTP_AUTHORIZATION, REDIRECT_HTTP_AUTHORIZATION or getallheaders() function.
REST API: Re-calculating cart totals has moved to the abstract cart callback so it can be shared.
REST API: Setting a custom price for an item will now return that price for the item not just update the subtotals and totals.
REST API: When adding an item to cart with a custom price, check if the product allows it to change.
REST API: Stock details now return for variations in the Products API (V2 Only). Schema updated to match.
REST API: Added headers CoCart-API-Cart-Expiring and CoCart-API-Cart-Expiration to be exposed with CORS.
REST API: Browser cache has been improved.

Deprecations

No longer use cocart_override_cart_item filter. Recommend using cocart_item_added_to_cart action hook instead.
No longer user cocart_cart_updated hook. Replaced with cocart_update_cart_before_totals hook.
