This is a final warning that if you are using containerd 1.X, you must switch to 2.0 or later before upgrading Kubernetes to the next version.

This is practically not actionable for enterprise users as there is still no LTS release in the v2.x series.
I suggest marking v2.2 as LTS.

v2.2 LTS should be maintained until 2027-11-06 at least.
The EOL can be extended later on demand: https://github.com/containerd/containerd/blob/main/RELEASES.md#support-horizon
