+* Fix and update list of markers in jpegoptim worker: allow to pass `com` instead of incorrect `comments` and add missing `xmp` and `none` [#188](https://github.com/toy/image_optim/issues/188) [@toy](https://github.com/toy)
+* Add `--skip-if-larger` flag to pngquant worker. The pngquant worker already does this, but this will make it fail faster.
