Today I released Meteor Slides 1.5.4. This tiny update changes the code for setting up the slideshow widget for WordPress 4.3, which will be coming out soon. This only updates how the widget is added to WordPress and doesn’t change the admin interface for the widget or how slideshow widgets display on the frontend of a site.
With this update Meteor Slides is fully compatible with the current version of WordPress, 4.2.2, and the next release, 4.3. I would definitely recommend that everyone take the time to update WordPress, Meteor Slides, and the rest of their plugins to the latest versions!
