Bukkit

GitHub release page

• Add chunk overrides for owned factions
• Add chunk overrides for nearby factions
• Dynamically react to permission changes, new factions, faction land claims, joining/leaving factions, etcetera, and update player permissions as needed
• Add a custom download permission to let individual factions decide what players can download

No known bugs, but there are several cases where performance may be suboptimal due to needing to update a large number of players or needing to figure out a large number of changes.
