Added a chat wizard for setting a bounty amount post-duel command in the GUI
Remove update checker
Only start Duels from one world, configurable in config.yml
Update deprecated pickup API
Added an option to hide the Duel winning title message
Added an option to hide the bet winning title message
Whitelist arenas/worlds and fix duel transportation, with PetTeleport-OG and HorseTp-OG support
Add EternalCombat support
Replace BountyHunters hook with PlayerBounties-OG support
Replaced Vault hook with DiamondBank-OG API
Removed Multiverse hook; world whitelisting now uses plain Bukkit world names with MyWorlds listed as a soft-depend to ensure managed worlds load before Duels
Bundled live TrueOG Network config files for plug-and-play deployment
Bundled default kits (chain, iron, diamond, leather, netherite, debuff, nodebuff) in the plugin jar
Removed WorldGuard region restrictions inside duel arenas
Fixed victory message formatting
Fixed kits equipping into an empty inventory caused by a delayed inventory reset wiping the kit
Added separate configurable end-of-match broadcast commands for bet and no-bet duels
Fixed diamond bet payouts so the total bounty equals the bet amount (the loser pays the winner, instead of both staking and the winner receiving double)
Added a message telling the bet maker when their opponent cannot afford the bet
Pluralize "Diamond"/"Diamonds" in messages based on the amount
Fixed a bug where a selected kit could not be de-selected, blocking own-inventory duels
Select a random kit and arena if none are selected
Strip kit-item NBT from outgoing packets via ProtocolLib so legacy clients (1.8+ through ViaVersion) can eat, draw bows, and hold items without desync, while keeping kit-item protection intact
Ported the per-player colored-glass arena boundary wall from EternalCombat-OG. For the duration of a duel, each combatant sees a client-side glass wall hugging the inner edge of the arena, so they cannot wander out mid-match. The arena's bounds are read straight from the smallest WorldGuard region enclosing its first spawn point, so existing arenas pick up the wall with no extra setup. Block type, view distance, and refresh rate live under arena.boundary in config.yml.
Hardened arena protections: combatants snap back if they leave the WorldGuard region, and outside players cannot damage anyone in the match
Three inventory modes in the settings GUI — Own, Mirror Mine, Mirror Theirs — each player fights with a clone, originals restored after, never staked in bets
Fixed winner losing XP after a duel
Merged in the retired DuelEnhancer-OG plugin: spectators forced into survival mode (e.g. by a WorldGuard region flag) are removed from spectating and teleported back to their original location

Planned:

Re-implement spectator mode using GxUI-OG
