Hi Folks
Given the momentum on CF2, it seems we should finalise CF 1.7 (which of
course doesn't preclude 1.7.1, whether or not we ever have a CF 1.8).
What's the current state of CF1.7? In particular, is there anyone out
there who is responsible for tidying up CF1.7 and declaring it *done*? I
had the impression that might be Jeff Painter. Is that right?
