It's that time of the year where a little refresh of QuickGraph (http://www.codeplex.com/quickgraph) is needed.
- New API to add and remove vertices from the graphs
- Important bug fixes in the shortest path algorithms (oops!)
- Support for MSAGL ( http://research.microsoft.com/research/msagl/ )
- QuickGraph.Data, provides data structures build graphs of databases (given a DataSet)
- QuickGraph.Heap, provides data structure to build graphs of SOS managed memory dumps (more later)
