1.0.1

This is a minor release of the Digraphs package. The main change in this release is the reintroduction of the three-argument version of DigraphAddVertices, which accepts a digraph, a number of vertices to add, and a list of labels for the new vertices. The removal inadvertantly broke backwards compatbility with some third-party pre-existing code that relied on this functionality in the Digraphs package (see Issue #264).

The second argument of the three-argument version was redundant, and so a new two-argument version of DigraphAddVertices, which accepts a digraph and a list of new vertex labels, was introduced in v1.0.0. Unfortunately, the concurrent removal of the three-argument version of DigraphAddVertices was not advertised in the CHANGELOG. Although the three-argument version has been reintroduced, it will remain undocumented, since there is no good reason for any new code to use the three-argument version.

The author contact data on the title page of the manual was also updated.

The changes in this version were made by Wilf A. Wilson.
