v0.21.0

Compare Source

This release patches the recent runc CVEs, as well as an issue with kind build node-image and docker v25.0.0+

Breaking Changes

• The default node image is a Kubernetes v1.29.1 image: kindest/node:v1.29.1@​sha256:a0cc28af37cf39b019e2b448c54d1a3f789de32536cb5a5db61a49623e527144

If you haven't already, please see also v0.20.0 release notes which had important announcements that still apply going forward.

New Features

• Upgraded go to 1.20.13
• Upgraded crictl to 1.28
• Upgraded containerd fuse overlayfs to 1.0.6
• Began marking some core images pinned in containerd, which may eventually make enabling imageGC safer
• kindnetd will ignore nodes with empty podCIDR, enabling some niche use-cases

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.
