FlowGate-Lite v1.0.4

🔧 Hub Routing Overhaul

This update fully rewrites and stabilizes the hub routing and fallback system. Focus: reliability, smooth player flow, and clean messaging.

✨ Improvements

🧠 Smart Hub Selection

• Added intelligent hub selection based on player count
• Automatically routes players to the best available hub
• Supports soft/hard limits for load balancing

🔄 Reliable Fallback System

• Players are now correctly routed when any server goes down

• Behavior:

  • → Sends to available hub if one exists
  • → Sends to fallback only if no hubs are online

• Works globally across all servers

🔍 Continuous Hub Detection

• Fallback server now continuously searches for available hubs
• Players are automatically moved when a hub becomes available
• No manual reconnect needed

🚦 Connection Throttling

• Added randomized delays (100–500ms) for reconnect attempts
• Added staggered delays (200–1000ms) when many players are waiting
• Prevents hub flooding during mass reconnects

💬 Messaging System

• All routing messages now come from messages.yml
• Clean and consistent user experience

Added messages:

• routing.searching → shown when player enters fallback

• routing.found → shown when a hub is found

• Removed redundant message spam from scheduler

🧩 Internal Changes

• Reworked LimboRouterListener for better tracking and cleanup
• Improved FallbackListener routing logic
• Added HubUtil#getBestAvailableHub() for smart selection
• Added HubUtil#isHub() helper method
• Fixed initial join handling via ServerConnectBlockerListener
• Made sendMessage() accessible across components

🐛 Fixes

• Fixed players not being routed correctly when servers go down
• Fixed fallback not connecting when hubs are unavailable
• Fixed hub detection inconsistencies
• Fixed message duplication issues
• Fixed improper routing during initial join

📌 Result

• Stable server switching
• Correct fallback behavior
• Smooth recovery from server downtime
• Clean, controlled messaging
• Scalable for large player counts

⬇️ Update Notes

• No config changes required
• Fully backward compatible
• Restart proxy after update (no reload)

Version: 1.0.4 Author: Terona / FlowGate

Minor Update

• Fixed and cleaned up information inside configuration YML files
• Removed leftover personal branding
• No functional or behavioral changes

🚀 FlowGate Lite — v1.0.2 (Stable Release)

✅ Fully Operational • Production-Ready • Battle-Tested

FlowGate Lite v1.0.2 marks the first fully stable and complete release of the Lite branch.

✨ What’s New in v1.0.2

🔁 Reliable Hub Recovery

• Players are automatically routed back to a hub the moment one becomes available
• No reconnect required, no manual commands

🛑 Zero Disconnects During Hub Outages

• If all hubs go offline, players are safely moved to the fallback server
• Eliminates “Could not connect to a default or fallback server” kicks

⏳ Smart Fallback Waiting System

• Starts and stops automatically, no duplication, no flicker

🧭 Improved Hub Commands

• /hub now:
  • Tries all hubs intelligently
  • Sends players to fallback if no hub is available
