Yes, I got that. Just wanted more explanation on the matter - of course
I am not an expert in software development and in industrial scale,
therefore it seems to me to be weird having those "epoches" - for there
is number positioning in versions like a.b.c.d - each number saying
about how significant development progressed, and there is "-e.f"
saying about patches in a distro being applied.

But thank You, Dan, and all others that took Your time to make things
clearer to me.
