DC/OS 2.1.3 Release Notes

Release notes for DC/OS 2.1.3, including Open Source attribution, and version policy.

DC/OS™ 2.1.3 was released on 17 December, 2020.

WARNING: Upgrading from DC/OS 2.1.x to DC/OS 2.2.0 causes all Docker containers, launched by Docker Containerizer, in any cluster to be restarted due to an issue that changes the name of the 'libnetwork' certificate. Because of this, we recommend you upgrade directly to DC/OS 2.2.1 or higher.

New customers, contact your sales representative or sales@mesosphere.io before attempting to download and install DC/OS Enterprise.
