Hi Jon,

Is there some documentation I could review about the changes to the bus system? It’s a feature I don’t use on a majority of projects, but I remember finding it to be little more than eye-candy when I used it last (i.e., the placing of net labels did all the work, and the blue lines and bus entries were only for appearance’s sake).  I’m interested to learn about the changes.

Cheers,
-Brian

We could include a note about this on the blog / forums to let existing users know (although from what I can tell, only a small fraction of existing users use them in the first place).
