Hi style7 there is a different kind of loop select for getting all the edges on a face boundary but it's not quite the same thing:

Another thing that's new in v5 with ACIS based filleting is that it will automatically extend the edges being targeted, like if you try to fillet just this one edge of your object:


It will actually automatically extend it to get the entire set you want:


However, in other spots it can decide to stop the chain if there is an opportunity to end the fillet like here:





I'll see about adding in an option for automatically extending a case like this by as far as possible and set up a chain selection helper method.
