WordPress is evolving, the way we are using images as well. I knew I had to simplify how Retina works by default (while keeping the same options), but also that I had to provide features to manage your image sizes better. Along with this, the features which were buried in the plugin are now much more obvious and easier to use (Replace Images, Regenerate Thumbnails, etc). This plugin will now evolve with WordPress, making sure best practices are easily actionable. Thanks for your support! And if you have some time, do not hesitate to let a little review here. 🙂
