🚀 MultiProxySync 2.2.0

This update introduces Redis Pub/Sub-based real-time synchronization and adds MiniPlaceholders support.

✨ Added

• Added Redis Pub/Sub real-time sync for faster cross-proxy player count updates
• Added MiniPlaceholders support
• Added the <multiproxysync_global_player_count> placeholder

⚡ Improved

• Improved player count refresh responsiveness across multiple proxies
• Improved shutdown cleanup behavior so proxies publish an update after removing their own Redis data
• Kept the original heartbeat sync as a fallback mechanism for stability

🐛 Fixed

• Fixed an early-known synchronization timing issue where player count changes on other proxies were not always reflected quickly enough after player joins, leaves, or proxy shutdowns
• Fixed extra Redis overhead caused by the placeholder implementation introduced in 2.1.0
