We might also want to decide what to do if bugs impacting security are 
uncovered (might be hard to decide what is exploitable. a double-free 
can in some circumstances be exploited, but I doubt any of us as the 
expertise to evaluate that)

For the mapserver (non-doc) repo, we're close to be ready to unplug 
Travis-CI now we have a github action job. The remaining thing would be 
to add coveralls support 
(https://github.com/MapServer/MapServer/issues/6299 created as remainder)

My software is free, but my time generally not.
