No, I don't. Thanks. But I don't think it is necessarily caused by 
incidental features. IMHO it is more related to the point #1 bellow...

However... there are some other changes that I don't like :(

1) object files linked into unit test are compiled into a separate 
directory now -- why?
2) output of the unit-test is captured and not shown. Instead some 
babbling about "1 file(s) copied." is being shown :(. My tests output 
the number of successfully completed test. Can I get this back?
3) failing test shows a screenfull of junk not related to the actual 
test (attached at the end of email)

Overall, my impression is that it is worse then it was before the 
upgrade :-(. Luckily, I've made a backup.
