SkBee 1.10.x will be the last version to support legacy console versions (ie: 1.8.x - 1.12.x)
Due to the many issues I have had to fix revolving around legacy servers, I find this too hard to continue offering legacy support.
Come 1.11 ... SkBee will strictly support MC 1.13+
That said, if you are using a legacy server version, please ensure to report any bugs you find ASAP so they can be fixed before I move onto SkBee 1.11
See GitHub for changelog.
