Eway Payment Gateway v4.5.0 has just been released. This updates Eway branding throughout the plugin.
Eway has changed its branding, so I’ve updated all references to the company name and changed the logo images to the new logo. I’ll gradually get around all of our Eway-related plugins and do the same.
You can update to the latest version from your WordPress plugin admin page. Here’s the full changelog for eWAY Payment Gateway.
