About Kata Containers
Kata rewrote its runtime in Rust and made it the default in 4.0.0
Kata Containers ships monthly, and the 3.2x series was steady infrastructure work — confidential computing plumbing for TDX and SEV-SNP, s390x block and memory hotplug, GPU coldplug, vCPU pinning, and a long tail of CI and packaging fixes. That series was also quietly staging a replacement: nearly every release carries runtime-rs commits alongside the Go runtime. 4.0.0 completes the handover, shipping the Rust runtime as the default.
