MasterPress 1.1.4 is now available.
This release contains an important compatibility fix for WordPress 4.5 to allow correct detection of the taxonomy term editing screen. Without this fix, any custom fields you have attached to custom taxonomies will not be shown at all in the editing form. Note also that MasterPress will still detect the edit screen correctly in older versions of WordPress, if you’re not ready to go to 4.5 yet.
Please install this update as soon as you can to ensure smooth operation in WordPress 4.5.
