Report for 2018-04-01 to 2018-04-30

This report covers the development in the linuxkit/linuxkit linuxkit/lcow linuxkit/kubernetes linuxkit/virtsock linuxkit/rtf linuxkit/homebrew-linuxkit moby/tool repositories. There were 241 contributions (PRs/Issues/Comments) from 27 individual contributors. 57 new PRs were opened and 51 PRs were merged. 23 new issues were opened and 9 issues were closed.

In April we released v0.3 of LinuxKit, our second proper release.

We had the usual slew of Kernel updates, bumped containerd to v1.1.0 (via v1.0.3), updated notary to v0.6.1, and bumped WireGuard to 0.0.20180420. We added support for USB storage and MPLS routing to the LinuxKit kernels and added support for read-only SquashFS based root filesystems.

Kubernetes was updated to v1.10, and CNI to v0.7.1. On the LCOW front, we updated to OpenGCS v0.3.7 and added more tests and benchmarks (including a bunch of improvements to the rtf tool).
