0.3.2 2020-09-10

    - Extended POD documentation to cover vertex and edge colors.
    - Renamed Graph::Nauty::EdgeNode to Graph::Nauty::EdgeVertex to have
      a consistent terminology.

0.3.1 2020-08-28

    - Added comparison of corresponding vertices to are_isomorphic(), as
      only the graph topology was taken into consideration previously.

0.3.0 2020-08-25

    - Switched are_isomorphic() to comparison of canonically labelled
      graphs, as done by nauty.
    - Added orbits_are_same() to compare orbits.
    - orbits are now enumerated based on nauty's canonical labelling of
    - Added installation instructions to the POD (GH#7).

0.2.0 2020-08-19

    - Added support for colored edges.
    - Fixed a typo in POD.
    - Added ppport.h (GH#1).

    - orbits() now accepts additional ordering subroutine-parameter to
      order nodes of the same color in order to remove a source of
    - Automatically generating minimum Perl version (GH#4).

0.1.1 2020-05-09

    - Added are_isomorphic().
    - Removed a source of nondeterminism of Graph::neighbours() (GH#2).
    - Initializing empty arrays (GH#3).
