Eway Payment Gateway v5.1.0 has been released. It prevents a fatal error in Event Espresso with no CSE key; supports WooCommerce HPOS; is tested up to WooCommerce 8.2.

Event Espresso

When Event Espresso was configured without a Client Side Encryption key, transactions failed with a fatal error. This won’t happen now, but you will still likely get an error from Eway like “V6111: Unauthorised API Access, Account Not PCI Certified”. This means that for your Eway account to accept transactions using the Direct Connection method, which this plugin uses, you must add a Client Side Encryption key. Please read the Eway FAQ for setting up a CSE key.

WooCommerce HPOS

WooCommerce added optional support for High Performance Order Storage (HPOS) in version 7.1, and whilst this plugin has long been compatible with that for the most part, it hasn’t declared compatibility. This version now announces that it is compatible, so WooCommerce won’t show it as not compatible.

You can update to the latest version from your WordPress plugin admin page. Here’s the full changelog for Eway Payment Gateway.
