Kangaroo 2.02 released
http://www.food4rhino.com/project/kangaroo
A few new features added, including the magnetic snaps seen in this video, soap-film membrane elements, tangential smoothing, and some more collision types.
Also fixed a bug in the angle component where the bending strength was not accurately using the input value. It is now properly independent of division lengths.
2-way solid-pt collision can also be used for mesh-mesh collision, by keeping all vertices of one mesh outside the volume of another.
Example collection updated for the new goals.
As always, any requests for future features welcome.

Excellent, sounds good. This explains why the elastica I was testing today weren't behaving as expected (i.e. they were dependent on division length). Does this mean I should just use the angle goal for bending now? Noticed that bend is still in there when going through the scripting API.

Yeahhh! Thanks Daniel. The funniest GH related period of time I had in while. Reading the release notes.
