To update your theme, please download the latest version at:

This update adds multiple small improvements, conflict fixes and greater efficiency for the PHP handlers. Additionally, a new feature is available via the settings page to disable lazy loading for the first post attachment (Above the fold / LCP) image of thread pages.
