Highlights

• Glow command — New /glow command for per-player colored glow outlines using PacketEvents virtual team packets. Supports all 16 vanilla colors, rainbow cycling, and per-color permissions. No scoreboard pollution — teams are sent directly to viewers and never registered on any Bukkit scoreboard.
• Join/Quit message permissions — Permission-based join/quit message formats via allium.join_message.<id> and allium.quit_message.<id>. Set custom formats with LuckPerms metadata.
• Chat system rewrite — ChatMessageManager, FormatChatListener, and PacketChatTrackerImpl significantly reworked for better PacketEvents integration and staff moderation features.
• Flight restoration refactor — FlightRestoration rewritten for improved Folia compatibility and reliability.
• Command management — CommandManager now caches the server's known commands map with a 2-second TTL, eliminating repeated reflection calls. Help command caches available commands per-player with a 3-second TTL.
• TP companion teleportation — Pet/entity teleport-on-TP moved from TP listener to dedicated TeleportBackListener for cleaner separation.
• Inventory snapshot optimization — InventoryManager.saveSnapshot() simplified to run directly on the calling thread instead of through SchedulerAdapter.run().

New Commands

Command	Description	Permission
/glow <color> [player]	Set glow color (e.g. /glow red, /glow dark_aqua)	allium.glow + allium.glow.<color>
/glow rainbow [player]	Enable rainbow cycling glow	allium.glow.rainbow
/glow off [player]	Remove glow effect	allium.glow / allium.glow.others

New Permissions

Permission	Description	Default
allium.glow	Base glow permission (grants all 16 color sub-permissions)	op
allium.glow.<color>	Per-color (e.g. allium.glow.red, allium.glow.blue)	via parent
allium.glow.rainbow	Rainbow glow mode	op
allium.glow.others	Target other players	op
allium.join_message.<id>	Custom join message format (value from LP metadata)	—
allium.quit_message.<id>	Custom quit message format (value from LP metadata)	—
allium.join_message.*	Wildcard — grants all join message formats	staff

New Config

join-and-quit-messages:
  join:
    enabled: true
    format: "&e%name% &7has joined the server"
  quit:
    enabled: true
    format: "&e%name% &7has left the server"
  broadcast-scope: server  # server, world, or global

Setting Custom Join/Quit Messages with LuckPerms

Set a permission with a metadata value on a player:

/lp user <player> meta set allium.join_message.vip.a "rift in the universe has spawned %player%"
/lp user <player> meta set allium.quit_message.vip.a "%player% has left through a rift"

Supported placeholders: %name% (display name, respects /nick), %player% (real name), %prefix% (Vault prefix), %suffix% (Vault suffix).

The first matching permission (alphabetical by suffix) is used. If no permission metadata is found, the default config format is used.

Technical Details

Glow

• Uses PacketEvents WrapperPlayServerTeams with TeamMode.CREATE (includes both team info and player entries in one packet)
• TeamMode.UPDATE for rainbow color changes, TeamMode.REMOVE for cleanup
• Packets sent to all online players including the target (the client needs to receive the team packet to render the colored outline)
• No Bukkit.getScoreboardManager() usage — completely virtual
• Folia-safe: no region-scheduled tasks needed

Join/Quit Messages

• Handled via standard PlayerJoinEvent / PlayerQuitEvent (main thread on both Bukkit and Folia)
• Permission metadata read through Vault Chat's getPlayerInfoString()
• Falls back to default config format if no permission match found
• Vanish check: vanished players don't show join/quit messages

Chat System

• ChatMessageManager rewritten with improved message storage and retrieval
• PacketChatTrackerImpl updated for better PacketEvents 2.11.1 compatibility
• FormatChatListener significantly expanded with new formatting options

SchedulerAdapter

• All scheduled tasks route through SchedulerAdapter which auto-detects Folia
• Folia path: uses EntityScheduler for entity-specific tasks, GlobalRegionScheduler for global tasks
• Bukkit path: uses standard BukkitScheduler
• No raw Bukkit.getScheduler() calls in new code
