Currently, a new feature for AntiCooldown and ServerSleeper is being rolled out: Auto-Updates!
With Auto-Updates the latest version of the respective plugin will be automatically downloaded and installed when starting your server
To prevent abuse a license key is required, which can be requested for free. Already in the Beta-Builds of AntiCooldown the Auto-Update-System was developed and regularly improved, but to test the stability of the system, a maximum of 100 license keys will be distributed for the first time.
License keys can be requested already now, the license keys will be issued in all likelihood by the end of this week, at the latest when all new versions with the Auto-Update feature have been released.
