What's New

Automatic Server Address Discovery

The dashboard's "API → Server" ping feature now works automatically! The API detects your server's IP address from the plugin connection, eliminating manual configuration for most setups.

Priority order:

1. Explicit server_address in plugin config (if set)
2. Auto-detected from plugin's connection IP

Plugin Changes

• Added server_address config option for manual override
• Improved disk spool cleanup for old batch files
• Fixed clientbound PLAYER_ABILITIES exemption handling

API Changes

• Auto-detect server IP from X-Forwarded-For / X-Real-IP headers
• Store detected address in callback_url for TCP ping feature
• Added constant-time token comparison for security
• Made permissive CORS explicit opt-in (CORS_PERMISSIVE_DEV=true)

Documentation

• Updated dashboard docs with auto-detection explanation
• Added manual override configuration example

Installation

Download async-anticheat-0.3.0.jar and place it in your server's plugins/ folder.

Full Changelog: 0.1.0...0.2.0
