In May we released v0.4 of LinuxKit. Kubernetes was updated to v1.10.3 and WireGuard to 0.0.20180531. There was the usual host of Kernel updates, including important security fixed for a new variant of speculative execution security issues. This also required an update to the Intel CPU microcode. We also enabled SCTP in the kernel config and made some improvements to the rtf tool and documented the release process.
