This is a API breaking change and breaks all downstream reverse dependencies. For example you may find it now shipping a different pkgconfig file (gexiv2-0.16.pc instead of gexiv2.pc). I think this should be done as a new package.

(We usually do major GNOME bumps in a mono PR on the wip-gnome branch, I think we will start this after @jtojnar finishes their travelling)

Ah, yes, should've thought of that, sorry.
Should I better close this PR? Also, #501267 is depending on this PR and is a GNOME 50 related (nautilus 49.4 → 50) - I'll close this as well, if you do not mind.

Since new packages can go to master, separate PR is fine.

closing this pr, and created a new pr #502190 as suggested
