The default leader election resource lock of `machine-controller-manager` has been changed from `endpointsleases` to `leases`.
Please make sure, that you had at least `machine-controller-manager@v0.43.0` running before upgrading to `v0.46.0`, so that it has successfully acquired leadership with the hybrid resource lock (`endpointsleases`) at least once.
Published docker images for Machine-Controller-Manager are now multi-arch ready. They support `linux/amd64` and `linux/arm64`.
Rollout freeze won't happen due to `Unknown` machines now.
The `machine-controller-manager` container now uses `distroless` instead of `alpine` as a base image.
