There are new labels available, e.g. for scheduling, which needs to be documented.

For reference only, this feature was a dev preview in 4.13 and very little documentation was added for 4.13, see https://issues.redhat.com/browse/CNV-21228
When you begin your research, you can refer to the 4.13 epic for additional info: https://issues.redhat.com/browse/CNV-10833
