About Kata Containers
With the Rust runtime shipped, Kata turns to GPUs and slimmer packaging.
Kata Containers ships monthly, and 4.1.0 is the first release after the Rust runtime became the default. It is consolidation work: the static release tarball is split by runtime, the GPU extension is built without depending on the monolithic image, NVIDIA libraries are chiselled down from a filelist, and kata-deploy stops shipping virtiofsd when shared_fs is disabled. Dragonball merged its three network device managers into one, EROFS backing mode became configurable, and the CI matrix churned across s390x, arm64 and ppc64le.
