Release notes for DC/OS 2.0.1

DC/OS 2.0.1 was released on 22 November 2019.

WARNING: The DC/OS 1.13.9 release includes a data format change for the persisted dcos-net state that, if you upgrade to release 2.0.1, can cause critical issues with dcos-net. Because of this, we recommend upgrading to release 2.0.4 or higher.

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