JanusMCD v0.2.3 - "The Fortress Update"

🛡️ Major Security & Feature Updates

🔌 Velocity Authentication (Single Sign-On)

Backend servers now fully trust your Velocity authentication.

• Trusted Velocity Logic: If a player is verified by Velocity, they skip local authentication on backend servers.
• Instant Play: Players linked in the Lobby are immediately unfrozen and allowed to play.
• Direct Connection Block: Players bypassing the proxy are automatically kicked.

🧵 Folia & Paper Compatibility

Full support for modern multi-threaded server architectures.

• Folia Native: Optimizations for Folia's RegionScheduler and EntityScheduler to prevent thread crashes.
• Async Teleport: Cross-region teleports are now handled asynchronously for zero-stall movement.

🤖 JDA 6 Migration

We've migrated to the latest Discord API (JDA 6.3.0).

• Future-Proof: Ready for Discord API v10 and upcoming changes.
• Performance: Improved interaction handling (Buttons/Commands).

💬 Adversarial Chat Filter

The old regex filter has been replaced with a smart Adversarial Pipeline.

• Evasion Detection: Detects and blocks leetspeak (h3ll0), normalization bypasses, and toxicity.
• Auto-Deletion: Offending Discord messages are instantly deleted from the channel.
• Strict Mode: Evasion attempts result in a full message block rather than a partial replacement.

🛑 VPN & Bot Protection

Hardened security against bypasses and API failures.

• Fail-Closed Logic: If a VPN provider's API goes down or times out, the connection is now BLOCKED by default (instead of allowed).
• Anti-Bypass: Fixed potential loop-holes where lag could allow players to skip checks.

🛠️ Fixes & Improvements

• Config: fixed redirect-unauthenticated not being respected on backend servers.
• Performance: High-performance UUID caching to reduce database load.
• Chat: Cross-Discord chat relay now correctly handles edits and deletions.
