This release introduces initial limited support for nerdctl and kube-proxy nftables mode.

Breaking Changes

• The default node image is now Kubernetes 1.30.0: kindest/node:v1.30.0@sha256:047357ac0cfea04663786a612ba1eaba9702bef25227a794b52890dd8bcd692e
• ipFamily config field is now validated
• While technically a breaking change, if the value you set here is now caught as invalid it was being silently ignored and creating an ipv4 cluster previously and you should correct your config
• Go 1.17+ is required for go install sigs.k8s.io/kind / building the kind binary
• Prebuilt binaries are available as an alternative to go install
• For local development make will automatically setup the correct go version
• Note that the go team only supports 1.21+ and major linux distros have 1.19+
• Future releases may increase this to a more current Go release
• Future release may adopt toolchain in go.mod to make this seamless if you have go 1.21+ installed even without our makefile. We highly recommend installing go 1.21+

New Features

• Initial support for nodes created with nerdctl
• Initial support for kubeProxyMode: nftables (ahead of Kubernetes 1.31+, see https://kind.sigs.k8s.io/docs/user/configuration/#kube-proxy-mode)
• Sweeping dependency updates, see commits for full details. https://github.com/kubernetes-sigs/kind/compare/v0.22.0...v0.23.0

NOTE: You must use the @sha256 digest to guarantee an image built for this release, until such a time as we switch to a different tagging scheme. Even then we will highly encourage digest pinning for security and reproducibility reasons.

NOTE: These node images support amd64 and arm64, both of our supported platforms. You must use the same platform as your host, for more context see https://github.com/kubernetes-sigs/kind/issues/2718

Fixes

• Correctly case kubeProxyMode: "none"
