A new update for GD Quantum Theme Pro is mainly a maintenance release that includes many important updates related to plugin loading and styles building, and many fixes for bugs reported in the past few weeks.
Loading of CSS and JS files was changed a lot in version 2.5, but that introduced some issues related to the customizer. Now, there are many changes related to better handling the customizer preview, the order of some actions, and registrations and enqueuing of the files. The SCSSPHP Library used to generate custom color styling has been updated and some additional changes related to this library included in the plugin to make the building process better.
The new version includes various important fixes: broken customizer preview in some cases, missing ‘approve’ action for topics and replies, and few other things.
