Release notes#
MKE 4.1.5 is a patch release focused on improving upgrade reliability and
air-gapped environment stability. The mkectl CLI no longer triggers unintended
k0s/k0rdent upgrades when it is used against older clusters, and ingress-nginx
migration has been enhanced for smoother upgrades and better coexistence with
the Gateway controller. Additional improvements include stronger CA certificate
validation, fixes to air gap registry namespace sourcing, and earlier detection
of stale k0smotron artifacts in air-gapped environments.
