MCR 20.10.x Release Notes

This document describes the latest changes, enhancements, known issues, and fixes for Mirantis Container Runtime (MCR) for versions 20.10.x.

Caution

In developing MCR 20.10.x, Mirantis has been transitioning from legacy Docker Hub-issued licenses to JWT licenses, as detailed below:

  • Versions 20.10.0 to 20.10.6: Docker Hub licenses and JWT licenses

  • Versions 20.10.7 and later: JWT licenses only

Using MKE with a JWT license to manage MCR causes MCR to log error messages, though the software does not fail.
