Artemis 2.2.0 has been released recently, with new content such as new monsters, new anomalies, and new torpedoes.
Your mission editor is still "the one" being used by almost everyone who makes missions in the Artemis community. Are you planning to update the editor? It would make a lot of people very happy :)
Otherwise would you consider transferring ownership of the project to someone else who is interested, or making them a collaborator of this repo? :)
