I should have pointed out that for most people, there should be
minimal to no API change with this release; the only change I needed
to make in my own code was that a type-class I had defined in
Graphalyze was removed as it provided the impetus for the ToGraphID
class mentioned below.

> no longer re-exported from `Data.GraphViz.Attributes.Complete`.

> * Dropped support for base-3.
