Yes, I see the problem. I take it you included 'aspdnsf/entity' in the 'do not generate friendly urls' field?
The reason for the change is a reversal in the order in which rules are processed. It used to be that the siteurls was checked first, then the cached tab dictionary. However, this doesn't allow for redirection of urls which also match the siteurls file, and doesn't reflect the fact that the site will only occasionally process siteurls.
I'll have a think about it and come up with a patch for you. I've got an ASPDOTNETSF setup I can test on.
