v0.9.0

Added

• Added the Graph.AddVertex method for adding a vertex. This replaces Graph.Vertex.
• Added the Graph.AddEdge method for creating an edge. This replaces Graph.Edge.
• Added the Graph.Vertex method for retrieving a vertex by its hash. This is not to be confused with the old Graph.Vertex function for adding vertices that got replaced with Graph.AddVertex.
• Added the Graph.Edge method for retrieving an edge. This is not to be confused with the old Graph.Edge function for creating an edge that got replaced with Graph.AddEdge.
• Added the Graph.Predecessors function for retrieving a vertex' predecessors.
• Added the DFS function.
• Added the BFS function.
• Added the CreatesCycle function.
• Added the StronglyConnectedComponents function.
• Added the ShortestPath function.
• Added the ErrEdgeNotFound error indicating that a desired edge could not be found.

Removed

• Removed the Graph.EdgeByHashes method. Use Graph.AddEdge instead.
• Removed the Graph.GetEdgeByHashes method. Use Graph.Edge instead.
• Removed the Graph.DegreeByHash method. Use Graph.Degree instead.
• Removed the Graph.Degree method.
• Removed the Graph.DFS and Graph.DFSByHash methods. Use DFS instead.
• Removed the Graph.BFS and Graph.BFSByHash methods. Use BFS instead.
• Removed the Graph.CreatesCycle and Graph.CreatesCycleByHashes methods. Use CreatesCycle instead.
• Removed the Graph.StronglyConnectedComponents method. Use StronglyConnectedComponents instead.
• Removed the Graph.ShortestPath and Graph.ShortestPathByHash methods. Use ShortestPath instead.

v0.8.0

Added

• Added the EdgeWeight and EdgeAttribute functional options.
• Added the Properties field to Edge.

Changed

• Changed Edge to accept a variadic options parameter.
• Changed EdgeByHashes to accept a variadic options parameter.
• Renamed draw.Graph to draw.DOT for more clarity regarding the rendering format.

Removed

• Removed the WeightedEdge function. Use Edge with the EdgeWeight functional option instead.
• Removed the WeightedEdgeByHashes function. Use EdgeByHashes with the EdgeWeight functional option instead.

Fixed

• Fixed missing edge attributes when drawing a graph using draw.DOT.

v0.7.0

Added

• Added draw package for graph visualization using DOT-compatible renderers.
