- Updated to mc26.1 - Mod versioning scheme is now `major.mc.minor`: - `major` is incremented on 'significant' feature changes, or breaking API changes (if applicable). - `mc` is never reset, and is incremented on every MC release, irrespective of whether a mod update was required. - `minor` is reset when `major` is changed, and is incremented on every update that does not change either of the previous two numbers.
