- Optimizing a folder full of images is several times faster, because they are now handled at the same time instead of one after another
- Images are compressed further than before, JPEGs in particular
- Colour profiles are now kept, so wide-gamut photos no longer shift colour after optimizing
- Modification times are kept on JPEGs as well, so a photo library sorted by date stays in order
- Fixed a batch stopping early when one file had a quote or a bracket in its name
- Fixed a crash when a selected file turned out not to be an image
- Fixed the button for adding more images being invisible on some systems
- Bitmap files are no longer accepted, because they cannot be optimized in place
- Image Optimizer is now available from the Snap Store, and takes up less room once installed
