It is great to see you are all enjoying this mod!
I have been very busy recently, but I could continue working on new updates at some point in the near future. As for updating the mod to be compatible with newer versions of Minecraft- it is very time consuming, and I might just end up waiting for the next major Minecraft update (1.13).
I have had some ideas regarding the theme of new content in the next major update. I am currently deciding between "The Great Martian Adventure Update" (this would make Mars a lot more fun to explore and settle), and "The Jovian Update" (you can expect this to be a kind of aquatic update ). Whichever one is not decided on should still be released- just later on.
