0.3.7 2021-10-04 - Replaced av_top_index() with av_len() to retain backwards compatibility with older Perl versions (GH#1). Removed ppport.h. - Fixed memory leaks in XS code. 0.3.6 2021-06-07 - Adapted the code to work with Graph v0.9717 and later (GH#8). 0.3.5 2021-04-06 - Increased the workspace size to handle larger and more intricate graphs. 0.3.4 2020-10-29 - Fixed segfaults caused by empty graphs given to are_isomorphic(). 0.3.3 2020-09-16 - Fixed issue with treating edge vertices of one color as the same. - Added canonical_order() to get the canonical order of graph vertices. - Extended POD documentation to cover vertex ordering. 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 vertices. - 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). 0.1.2 2020-08-11 - orbits() now accepts additional ordering subroutine-parameter to order nodes of the same color in order to remove a source of nondeterminism. - 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). 0.1.0 2020-05-01 - Initial release.
