v1.0.0

Operating System Manager (OSM 1.0)

We are thrilled to announce Operating System Manager v1.0.0 a.k.a OSM 1.0 🚀

OSM is our open source tool responsible for creating and managing the required configurations for worker nodes in a Kubernetes cluster. It decouples operating system configurations into dedicated and isolable resources for better modularity and maintainability.
