Sorry StanGromer for the confusion caused. Agree, it makes sense to refer to the major releases as they are the main and default vehicles with significant additional value. The focus of minor releases such as 21.3 is primarily defect fixes and minor tweaks to existing features.
Hope that clarifies.
