- In addition to gems in the :default group, also preload gems in the group specified in the RACK_ENV environment variable, or :development if RACK_ENV is unset. This is similar to Rails behavior. (Jonathan Davies)
- Allow polling to be forced on with --force-polling. If you have mounted the files over NFS, and are editing them remotely, then file system events are not fired, so the reloading doesn't work. Force it to poll with --force-polling and it will work in this case. (Jamie Cobbett)
- Changes for compatibility with listen 1.0 and later, which it now requires.
- Use optimistic version constraints
- Messages from mr-sparkle now go on stderr, not stdout, just like unicorn's log messages
