In this case, the 2nd picture.

I've created a pdf of both cases (straight and rounded.

I just emailed SteveZ if I could send PDF to him to post.

A taper on one or both sides of a straight edge is a bevel. A taper down into a hole is a chamfer.

I think it's gotten a little crossed up in what we're talking about.

There's the chamfer:
         _
        /  \
       /    \     cross section of board edge view
       |     |

And the chamfer:
      _____
                  \
                   \     top view of board corner
                    |
                    |

I've looked, but never seen a good definition that provides a distinction between the two.  And what's a bevel?  FWIW, I''ve always called the first a bevel, and the second a champfer.
