Particle Type | You can now set the type of particle that a gravity tube uses. Please note that only a few particle types are colorable and even then some might behave incorrectly depending on your server version. You can set the type with /gt settings type <type>. This does support tab completion.
UpdateChecker | Fixed a version parsing issue. You will only get notified of a new version if the version on Spigot is "greater" than the version you have installed.
