Making mistakes is fine, we all make them.

I was expecting you to answer saying, "Yes, I mean KDE Plasma and the reason I

When updating minimum versions we need a reason (much easier if the reason is 
"the policy says so")

Right, i miscounted, should be 3.24.

But see my other email for a policy :)
