... but the op has stated a valid reason for monitoring new links, to evaluate the success of changes made to a site.
Without repeating myself yet again, read my previous posts about it.
I for one would be concentrating on other aspects of link building / checking.
My site has been going for years and I cannot remember the look and design of sites that I have linked to. Yes, I do check to see if they still link - if they've gone up or down in PR etc.
The OP was quite specific in their request... what links were added since the change.
If the content hasn't changed, then don't worry about it (unless the site has become spammy). If it has become spammy looking, then concentrate on the old links being removed.
