Updates for 1.21.6+ (also works with older versions)
TabListPing 2.02 makes changes to maintain compatibility with Paper 1.21.6+.
It still works with older versions and Spigot.
Paper 1.21.6 changed the Keep Alive update to run every second, which is ridiculous. TabListPing will wait at least 5 seconds before updating the ping time.
Paper is also planning to remove one of the login events and has been nagging server owners about it. TabListPing now uses a different event which is not affected by the change. This should also improve compatibility with other pluging that involve themselves with the login process.
