plan to announce 5.20.1 as new Maxima release



Hello,

since the 5.20.1 release last week, to the best of my knowledge
there has been just one minor patch on the 5.20 branch
(share/contrib/implicit_plot).
So at this point I am inclined to announce 5.20.1 as the new
Maxima release instead of waiting for additional patches.
I'll go ahead with an announcement tomorrow.

I thought about a 5.20.2 release but that was before I figured
out that there wasn't anything new & significant on the branch.

FWIW
