Lightning now properly strikes on spawnpoints on special waves.
Fixed an issue where players somehow warping/cheating out of the arena world get kicked from the server when discovered.
Added MagicSpells support. Use the magicspells.yml file to ban certain spells from the arena either for the whole session, or only during boss waves.
Fixed the Heroes death conflict. MobArena and Heroes should now play nice together. Further Heroes support is planned for upcoming releases.
MobArena will no longer support the discontinued Permissions 2.x and 3.x permission systems. Recommended permissions systems include PermissionsBukkit (defacto standard) or PermissionsEX.
Redstone, doors, and torches will sometimes drop as items on explosions. Using repair-delay: 0 dodges this.
