Release Notes

This document describes the latest changes, enhancements, known issues, and fixes for Mirantis Kubernetes Engine (MKE) for versions 3.4.x.

Caution

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.
