Description

• Document that all Operator versions use a single CRD API version. The CRD revisions between Operator versions don't introduce any breaking changes so they are backward compatible.
• OLM seems to keep the latest CRD revision regardless of in which order the Operator versions were installed. (This needs double checking.) Make sure to document this. Add a note for non-OLM installs that they should mimic this behaviour (installing latest CRD revision).
• Document that using a field introduced in a newer Operator version with and older Operator version is not supported and will lead to Operator failing on an unrecognized field.
