+## Attention Needed
+
+* CentOS 8 has reached End-Of-Life (EOL) on January 31st, 2022. It will no longer receive any updates (including security updates). Support for CentOS 8 in KubeOne is deprecated and will be removed in a future release. We strongly recommend migrating to another operating system or CentOS distribution as soon as possible.
