42.3. New Features

  • The v1beta3 API is no longer supported in kubernetes

    Using v1beta3 in configuration files is no longer supported. Creating a v1beta3-style object with the kubectl command will fail with the following error:

    error validating data: the server could not find the requested resource; if you choose to ignore these errors, turn validation off with --validate=false

    Using the --validate=false option will create an object, but the object will appear as a v1 object instead.

  • A separate cockpit-docker subpackage is now shipped

    Previously, the Cockpit docker support was shipped with the cockpit-shell subpackage. Now, the cockpit-docker subpackage is available to be installed separately on Red Hat Enterprise Linux and is included in the OSTree available for RHEL Atomic Host.

  • Cockpit has been rebased to version 0.93

    Most notable changes:

    • Distribute licenses of included components in the source RPM.
    • Reworked TLS certificates for Cockpit.
    • Cockpit now offers to activate multipathd for multipath disks.
    • Added user interface for OSTree upgrades and rollbacks.
    • Added OAuth login support.
    • Add SOS report to the User Interface.
    • Added support for the Tuned power management tool.
