Full Changelog

OmniPanel v18.9.17 is the result of a long series of upgrades, repairs, system merges, compatibility fixes, GUI improvements, integration work, moderation expansions, and internal cleanup carried out across the recent development cycle.

This release brings together the major OmniPanel work completed from the recent month through the latest builds, while preserving the latest architecture and removing old duplicate routes that caused conflicts.

The goal of this release is simple:

• Keep OmniPanel panel-first.
• Keep one authoritative implementation for each feature.
• Remove duplicate listeners, duplicate menus, duplicate API registrations, and old legacy routes.
• Preserve newer working systems.
• Improve compatibility with modern Paper, Spigot, Bukkit, LuckPerms, Geyser, Floodgate, DiscordSRV, PlaceholderAPI, Simple Voice Chat, and connected add-ons.
• Make /panel the central control point for server administration.

2. TAB System — Full Rebuild

TAB was one of the most heavily repaired systems in this development cycle.

Root problem fixed

Older OmniPanel versions had several competing TAB writers:

• Core171Support
• TabStabilityRuntime
• OmniPanelAdvancedRuntime
• RuntimeHardfix251
• Stable154Patch
• Parts of Core159Support

These routes could overwrite one another, which caused TAB flickering, missing player names, missing ranks, broken headers/footers, repeated updates, and conflicting scoreboard/list-name changes.

Rebuild

• Added TAB diagnostics.
• Added TAB refresh controls.
• Added TAB reload controls.
• Added TAB reset support.
• Prevented Chat Color Ranks from becoming a second TAB writer.
• Prevented Staff Mode from becoming a second TAB writer.
• Prevented old rank systems from rewriting TAB independently.
• Preserved modern TAB behavior while restoring colored names safely.
