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.
