V4A and V4X (version designations)

V4A and V4X are version designations used to differentiate updates or iterations of a specific product, software, or system. "V4A" typically indicates the fourth major version with a minor revision labeled "A," suggesting initial updates or improvements after the initial release. "V4X" similarly denotes a fourth major version but with a different revision, often implying a different set of updates or features. These labels help users and developers identify the specific iteration, track changes, and ensure compatibility, without implying incremental quality differences. They serve as a clear way to manage development progress and updates systematically.
