It's been a long time, but there is an update again.
First of all thanks to @PXAV ( https://github.com/PXAV) who wrote new features.

He added the following:

• Add no-damage mode: You can now turn on damage in the config, so you can kill players with a pickaxe for example. Setting this option to true will use the normal system where you can't take damage.

• Spectators can now see the score of the session they are currently watching

• You can now configure what recoil enchantment strength the stick should have

And now fixes I have written:

• In higher versions it often happened that the bett was bugged... this should be fixed now.

1.17 support is planned but not started yet!
