Overview
This update brings compatibility with the latest Xenforo 2.2.9 and moves all Nulumia themes to use the One-Click Archive import format. From now on, you can download style packages as a single zip file and import directly in your Xenforo backend. This means you will no longer have to manually upload files via FTP, nor import XML files...
