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.

> - [WebP](http://en.wikipedia.org/wiki/WebP) output support added.

> - `Bb` has been renamed `BoundingBox`.

> no longer re-exported from `Data.GraphViz.Attributes.Complete`.
> * The `ToGraphID` class provides a common wrapper to help create
> cluster identifiers, etc.
> * Cabal's `Test-Suite` functionality is now used. As part of this,

> exported by the library.
> * The new `Benchmark` support in Cabal-1.14 is now used for the
> benchmark script.
> * Dropped support for base-3.
> * The `Data.GraphViz.State` module is no longer exposed, as there's no
