 === Machine Config Operator
 
+With this release, you can now garbage collect unused rendered machine configs. By using the `oc adm prune renderedmachineconfigs` command, you can view the unused rendered machine configs, determine which to remove, then batch delete the rendered machine configs you no longer need. Having too many machine configs can make working with the machine configs confusing and can also contribute to disk space and performance issues. For more information, see xref:../post_installation_configuration/machine-configuration-tasks.adoc#machineconfig-garbage-collect_post-install-machine-configuration-tasks[Managing unused rendered machine configs].
