This release has been uploaded to http://www.pushface.org/components/bc/ (which at present the same place as the old URL http://www.pogner.demon.co.uk/components/bc/). The change that will make most difference to users is a Great Renaming; For Containers with Bounded, Dynamic and Unbounded forms the concrete types no longer include the form name; thus, BC.Containers.Maps declares Abstract_Map, while BC.Containers.Maps.Unbounded declares Map. The concrete Lists are now declared as plain List rather than Single_List, Double_List (there is no Abstract_List, perhaps there should be!). The concrete Graphs, Vertices and Arcs are now declared as plain Graph, Vertex and Arc (and the abstract types in BC.Graphs are Abstract_Graph, Abstract_Vertex, and Abstract_Arc). Besides that, Maps now have the standard Container generic type Item as the range, and the Map generic type Key as the domain. If you are a Map user, you'll have to change your code's logic (as well as the type names, see above). Added generic Copy, Filter functions to BC.Containers.
