AVAST roadmap available?

Since I’ve posted re the new version’s apparent increase! in memory usage affecting my ancient system somewhat adversely, I was wondering if there’s a roadmap (graphic, interactive, please) similar to what I sawr once for OS 360 that illustrated (at least functionally, not at the module level) how stuff was connected. I’d be innerested in seeing a comparison, though, also, between successive versions that listed aggregate memory sizes; or maybe a nice bar graph…

Thanks.
