Please add support if not. Thank you!

5.x only supports minecraft 1.11.2 you will need to update your server

So you never have plans of making an updated 1.8.9 version? There are still a lot of people who use that version.

nope. i have no plans of going backwards in versions

it should compile find against 1.8.9 however so if you cant update you coild try to compile it yourself for 1.8.9
