--- features: - | Add ``--group`` option to the ``command list`` command to filter the commands by group name: ``openstack command list --group volume`` will list all Volume commands for the selected API version. Use ``--os-XXXX-api-version`` to select a specific API version for the desired APIs. This provides an alternative to searching help output to list the comamnds available for specific APIs. Note that the ``--group`` argument is used as a simple substring search in the Command Group column. [Bug `1666780 `_]
