Highlights from this release include network policy support using sigs.k8s.io/kube-network-policies (thanks @aojea!) and support for building node images from pre-compiled Kubernetes releases (thanks @dims!).
For building images, see the docs at https://kind.sigs.k8s.io/docs/user/quick-start/#building-images
Breaking Changes
- The default node image is now Kubernetes v1.31.0:
kindest/node:v1.31.0@sha256:53df588e04085fd41ae12de0c3fe4c72f7013bba32a20e7325357a1ac94ba865
New Features
- Out-of-the-box support for network policy via sigs.k8s.io/kube-network-policies
- Advanced users can still disable kindnetd and install your own CNI with https://kind.sigs.k8s.io/docs/user/configuration/#disable-default-cni, however note that this is a "power user" feature and KIND does not offer support for any third-party CNI
- Support for building node images from existing Kubernetes releases
- NOTE: For Kubernetes releases before v1.31.0, this will result in larger images because kind opted in to compiling out remaining in-tree cloud providers with a build tag when publishing images. For v1.31.0+ there is no difference.
- See: https://kind.sigs.k8s.io/docs/user/quick-start/#building-images
- Support for loading multiple image archives in
kind load image-archive- NOTE: it is still more efficient to do a single archive in most cases
- Migrated to skipPhase in Init/JoinConfiguration instead of the kubeadm flags, making it possible for users to cutomize the phases (at your own risk!) with config patches
- powershell completion
- Updated dependencies, including, but not limited to:
- containerd 1.7.18
- runc 1.1.13
- go 1.22.6
- CNI plugins to 1.5.1
- pause 3.10
- Docs and clarification for third party install options including scoop and winget

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 #2718
Fixes
- Fix kubeadm v1beta3 config template for kubeProxyMode: none
- Stop disabling LocalStorageIsolation for rootless clusters (which no longer appears to be necessary to avoid crashes)
