Added MC 1.21 support.

Added MC 1.20.3-1.20.4 support (thanks to @BoomEaro)

Added 1.19.4 support (thanks to @BoomEaro)

· Added MC 1.19.3 support (thanks to @BoomEaro); · Added MC 1.7.X support (thanks to @RaphiMC); · Removed useless spawnPosition from config. Now spawn position depends on client version, to avoid crashes. This should resolve problems for Pterodaktyl users with incorrect configuration parsing.

Server will create new one with new or changed parameters. You also should save old config to paste required data in the new one. Thanks everyone who contributed to this project!

Added test support for 1.18

Added BungeeGuard support. Don't forget to recreate settings file.

Hello everyone! This update comes with new cool features: * Multiple versions support (1.8 - 1.17). Now you don't need to use protocol hack on proxy side! * Ability to send title on join. * Optimizations and code improvements.
