General

Cluster Management Console navigation menu style was adapted to match the new Dynatrace menu style.
Dynatrace Managed is now also supported on CentOS 8 Stream

The installer will automatically discover the operating system mode and adjust its configuration. To make it work, additional semanage (SELinux Policy Management tool) package has to be installed in your system. See Enable or disable SELinux for more details.
