RockSolid 2.1
This update will break any fluids in your world!
RockSolid 2.1 changes the fluid system to be much nicer, more compact and modular. Fluids now are stored in an enum which will in the future be modifiable through the API, and only a single fluid tile is registered to the game no matter how many fluid types exist.
Basic Lantern crafting has been temporarily disabled until the glitch causing infinite shining cluster duplication is fixed.
No testing of the new fluid system has been done in LAN or dedicated servers yet and cannot be until RockBottom 0.0.23 is released, but it should all work fine.
RockSolid 2.1 uses RockSolidAPI 2.1, which you can find here: http://maven.raphydaphy.com/com/raphydaphy/rocksolid/RockSolidAPI/2.1/
