In the WordPress 4.5 release, WordPress made significant changes and updated the core jQuery library. This caused many issues with various WordPress themes and plugins in the industry that were dependent on jQuery. Realizing this, our development team took immediate action, making sure that all Themify themes and the Builder plugin are compatible with the latest WordPress update. Thanks to the hard-work of our dev team, we were able to release a new update on the same day that the WordPress 4.5 was released. Aside from making sure all Themify themes/plugins runs smoothly with WP 4.5, we also included multiple bug fixes, and an improved user experience when using the Builder by making the Builder lightbox load faster. It is now safe to update your WordPress and our themes/Builder to the latest version.
