v0.12.0 has been focused on stability, with improvements and fixes for support rootless and cgroupsv2, and bringing support for s390x architectures.

Breaking Changes

• The default node image is a Kubernetes v1.23.4 image: kindest/node:v1.23.4@sha256:0e34f0d0fd448aa2f2819cfd74e99fe5793a6e4938b328f657c8e3f81ee0dfb9
• The haproxy image used for multiple control-plane cluster is distroless now

New Features

• Pods running at different nodes have different product_uuid
• Support for s390x architectures
• Adapt kind to handle the label migration from node-role.kubernetes.io/master to node-role.kubernetes.io/control-plane
• Base image updates
• Containerd version 1.5.10
• Crictl 1.23.0
• CNI plugins 1.1.0
• Containerd containerd/fuse-overlayfs-snapshotter 1.0.4

New Node images have been built for kind v0.12.0, please use these exact images (IE like kindest/node:v1.23.4@sha256:0e34f0d0fd448aa2f2819cfd74e99fe5793a6e4938b328f657c8e3f81ee0dfb9 including the digest) or build your own as we may need to change the image format again in the future :sweat_smile:

NOTE: these node images support amd64 and arm64 now. It remains possible to build custom images for other architectures (see the docs).

Fixes

• Enable sysctl route_localnet on node images to allow nodes dns to work
• Only mount /dev/fuse on rootless environments
• Fixed node labels assignments from configuration
• Fix docker+cgroup2+rootless initialization
• Fix sysbox runtime regression on docker in docker
• Fix support on distros without systemd and WSL2
• Fix kind load docker-image if all images are already present
