It could be a new field named "dotted_activity_version" or simply "version" or something else. An activity author who cared could then provide both, a decimal and a dotted activity version.

Basically, the old activity_version field would be a like a build number, increasing for every build, as we did before. It would be optional in Sugar 0.88. The "real" user-visible version number would be the dotted one in a different field.

I've created
and wrote several options of your proposal(how I understood it)
in http://wiki.sugarlabs.org/go/Features/Dotted_Activity_Versions#Detailed_Description

Also I pushed it to "Feature Ready for Release Manager" group though
this feature doesn't meet all requirements(there is no owner, I guess it
will be trivial to code it) but it let us do not forget about this
