Other support changes

Cloud platform support

In the past, Dynatrace offered a three-month upgrade grace period for upstream Kubernetes distributions, Red Hat OpenShift, and VMware Tanzu Application Service due to the offset between delivery schedules. As of May 2020, Dynatrace provides nearly same-day support for all container platforms. Thus our support model no longer requires the three-month grace period. For all OneAgent releases prior to May 2020 (earlier than OneAgent version 1.191), Dynatrace will extend support by three months to honor pre-existing OneAgent installations based on the previous support model.

Kubernetes

  • OneAgent version 1.191 will be the final release supporting Kubernetes versions 1.14, which was de-supported by the Kubernetes community in April 2020.

OpenShift

  • OneAgent version 1.189 introduces support for OpenShift 4.4.
  • OneAgent version 1.191 will be the final release supporting OpenShift versions 4.1, which was de-supported by Red Hat in April 2020.
