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 has been responsive for years now, scaling the slideshow images down for smaller screens and devices. But WordPress 4.4 adds new built in support for responsive images using srcset. What this means is that rather than loading the full size images and shrinking them at smaller sizes, it will actually detect the size of the screen or device and load smaller images. This will reduce the file size of the images that are loaded on smaller screens, speeding up the load time of your websites!
