<h1 id="breaking-changes">Breaking Changes</h1>

- 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+
