First thing this list requires, is the guilty revision, if known. Its kinda hard right now to look for those untested...

Hello Everyone,

To get trunk in a good state as soon as possible, it's important that we
all pull together.

I appeal to everyone to stop working an any fancy features (in the
branches, too) and instead have a look at bugzilla. We have 36
regressions there. And there's also a wiki page:
http://reactos.org/wiki/Buglist
I started assigning the bugs to the ones who have probably caused them.
