Newfish is an ever changing RDoc template, as it reaches a point of
design “beauty” it gets spun off as a new rdoc format. Think of it as
“edge” rdoc-fish.
This new release updates the template to conform to the latest version
to RDoc+ (v0.5.0). The version number has also been bumped to match that
of RDoc+ to serve as a better marker for interrelated versioning.
