Mod authors can now simultaneously support multiple versions of Cosmoteer within a single mod package. To do so, the mod author should add additional 'mod.rules' or 'mod_*.rules' files, optionally inside sub-folders if desired. Cosmoteer will then look at the 'CompatibleGameVersions` listed in each file and automatically select the one that best matches the current game version. (This functionality has also been retroactively added to the 0.29.0 beta branch.)
