KubeAdmiral has seen continuous development with many improvements made to both its features and stability since its open-source release. It has also been battle-tested through its extensive use in our internal environments. Thus, we believe that KubeAdmiral is now production-ready and are pleased to announce the official release of version 1.0.0.

This release reflects the achievements made by the community and developers over the past year. Thanks to all the contributors who helped make this release happen!
