Space now has a setup command. Please note, this command can only be used by OP players. The command is "/space setup" and may cause instability. It is only to be used if you are struggling to set up the plugin to make things easier for you.
Item gravity is now fixed in all worlds and will work, as it was broken from version 4.7.
Mobs will now only have their special effects in oxygen-deprived worlds.
Rockets unfairly killed players who used them, this was a very high priority issue and has been fixed.
The rocket GUI also now only adds the correct amount of planets.
