Current download

Verify before deployment
Use the SHA-256 displayed beside each download link to verify both JAR files before installing them. Never install a plugin JAR received from an untrusted mirror or through a private message.
Linux checksum command
sha256sum shieldplay-agent-0.1.0.jar && sha256sum ProtocolLib.jar03
Upgrade safely
- Back up plugins/AntiCheatSaaS/config.yml and note any Owner dashboard X-Ray override.
- Replace both JAR files while the server is stopped, keeping ProtocolLib in the plugins directory alongside the ShieldPlay agent.
- Start the server, run /anticheat status and review the dashboard heartbeat.
- Validate one staff GUI login and one webhook Test action before a busy session.
