pgchem::tigress vs. OpenBabel 2.4.0

OpenBabel 2.4.0 is released, the build process worked flawlessly, 100% tests passed.

Now I have to see if the Tigress still likes it...

Well, pgchem::tigress builds against OpenBabel 2.4.0 without errors, but will it work?

Yes, pgchem::tigress works with OpenBabel 2.4.0 without any notable alterations, except changing:

OPENBABEL_SOURCE=openbabel-2.3.2

in the Makefile to:

OPENBABEL_SOURCE=openbabel-2.4.0

As always with .0 releases, subtle issues might be lurking below the surface, though.
