I just released Meteor Slides 1.5.5. This is a small update that adds support for responsive images using srcset in WordPress 4.4 and fixes some Twenty Sixteen theme conflicts.
Meteor Slides 1.5 adds responsive slideshow support, touch navigation, an improved slideshow widget, new translations, and updates jQuery Cycle.
I have been building more responsive websites lately and receiving more and more requests from users for responsive slideshows, so I have updated the slideshows to scale automatically.
If you are using a fixed width theme the slideshows will remain unchanged at their original dimensions. But if you are using a fluid or responsive width theme those are used as the maximum dimensions and the slideshow will scale, shrinking to fit the theme on smaller screens and devices.
Any custom slideshow templates, stylesheets, or scripts you are using would have to be updated from the default versions in 1.5 to add this responsive functionality.
