Release notes

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

You must select "Overwrite files during install/upgrade" when upgrading to this version.


This update adds numerous bugfixes and improvements, including the ability to defer CSS and script tags in the footer. Using defer for scripts adds an additional layer to prevent render blocking of certain resources, and can occasionally improve speed scores.

In addition, a new feature has been added to use responsive avatars, which load smaller avatar sizes - including Gravatars! - on mobile screens. This can further help speed scoring when penalized for larger avatars on mobile devices.
