WooCommerce Blocks 5.3.0 Release Notes

A new version of WooCommerce Blocks has been released! Version 5.3.0 is now available for download from GitHub and WordPress.org.

This release includes a number of enhancements, bug fixes, and some behind-the-scenes work to allow third party extensions to integrate with the Cart Block.


Getting ready for the future

Two changes have been made when it comes to adding WooCommerce blocks to the new block widget and the Customizer block widget editor:

Block transforms are now available for legacy widgets that have a block equivalent: Product Search, Product Categories and Recent Product Reviews.

Additionally, the Cart and Checkout blocks will no longer be available in these two areas.

Bug fixes

We are happy to announce that the missing translations bug from the Cart and Checkout blocks has now been fixed. Along with other Cart and Checkout block bugs, we managed to fix bugs related to adding products to the cart, namely adding out of stock products from blocks with products, and updating the Mini Cart widget when purchasing from the All products block.

Working with Blocks

We added a new experimental integration point that will allow extensions to register a PHP callback that will be executed when the cart/extensions endpoint is hit. Blocks will use this endpoint to update the cart from the server, giving extensions a chance to modify the cart, or do any other server-side processing.

An experimental slot has been added to the Discounts section in the Cart Block’s sidebar, where extensions can render their own components.
