This document describes the latest changes, enhancements, known issues, and fixes for Mirantis Kubernetes Engine (MKE) for versions 3.4.x.
In developing MKE 3.4.x, Mirantis has been transitioning from legacy Docker Hub-issued licenses to JWT licenses, as detailed below:
Versions 3.4.0 to 3.4.4: Docker Hub licenses and JWT licenses
Versions 3.4.5 and later: JWT licenses only
Using a JWT license with an MKE instance that manages MCR causes the engine to log error messages, though MCR does not fail. This applies to MKE 3.4.5 and earlier.
