The default heuristic now attenuates the base heuristic as well as the boost. Essentially this:
<base heuristic> + <boost> / <attenuator>
is changed to this:
(<base heuristic> + <boost>) / <attenuator>
Why? Would anyone in their right mind have CNAME chains seven or eight names deep? Well I can't speak to their state of mind but yes, yes they do. It's not a huge problem but the change should clear out some names which were only seen a handful of times some days ago.
