Interesting, however I found this in the mozjpeg readme: > MozJPEG is a patch for libjpeg-turbo. Please send pull requests to libjpeg-turbo if the changes aren't specific to newly-added MozJPEG-only compression code. This project aims to keep differences with libjpeg-turbo minimal, so whenever possible, improvements and bug fixes should go there first. So they still rely on upstream development of libjpeg-turbo. Unless the readme is out of date and they don't bother syncing with libjpeg-turbo now.
