 as well, not aware there were problems with doing so.

 so long as we gradually update it - per the approach you're currently
 following - there aren't any concerns, at least from my perspective.

 Ok. I though you were referring to a specific known build failure that
 would occur in gimp2 if we were to update glib2 to a newer version.

 > Given that Cairo 1.17.4 has been in use for a few months now - without
 any known issues (I believe?) - is it worth the effort of reverting to
 1.16.0? (If nothing else, we'll need to rev-bump every direct dependent.)

 Yeah let's keep it then. I'll fix the livecheck to only track stable
 versions again.
