This update has quite a lot of features. I'd recommend reading the changelog below.
Changelog:

• The space generator has meteors - obsidian, stone and ore spheres that spawn at surface level
• A coal generator has been added to provide an alternative power source to the solar panel
• Added the tank refiller - When provided with power and oxygen (of over 25 units each) and a non-full oxygen tank is put within, it will fill up the given tank
• The tank refiller can refill oxygen tanks in planets with oxygen
• Full WorldGuard support ("space.regionbypass" to bypass)
• Custom lightsabers have been added. Configurable in the config.yml, and obtainable in the quantum workbench
• Most commands can now be run from console (GUI commands excluded)
• "/Space give" added to give users items
• The cheat GUI is now dynamic and will expand accordingly to accommodate for the items added
• Legacy item convertor added to start to add NBT to items so Space can better read them and provide better update support
• Photonic barriers now have sound
• Lightsabers now have sound
• Trashcans added (with sounds). Right-click to open, or shift right-click to place
• Updating the adamantium sword now takes the correct amount of money
• Fire and ender sword no longer have the same model data
• Elevators added
• New airlocks now no longer work when disabled
• Legacy rockets entirely removed
• Oxygen and energy now properly load into machines on restart
• LOTS of redundant code and optimisations.
• Smoother lightsaber actions added

All of the new items added in the changelog above will be on the wiki within the next 24 hours.
Enjoy!
