Thanks for the explanation.

So there is a version number indicated elsewhere than in the tags for
some minetest packages?  (Is this data in the package's git repo or in
e.g. minetest repo metadata?)  That is, the minetest updater always uses
"blessed versions" (not just random commits), such that "revision" will
always be "0"?

Are current minetest packages like this formatted like 'gnash' above?

That's the message I quoted ;)
