WooCommerce v4.2.0 contains 26 blocks. These have now been catalogued. See WooCommerce.
Update: 12th June. The API reference for v4.2.0 has also been rebuilt.
Note: The blocks delivered in the WooCommerce plugin are developed in the WooCommerce blocks plugin, which is always a few changes ahead. Ironically, the documentation for this plugin is now slightly behind.
