Complete!
I missed it with the first read through, but the clue is output saying "Skipping packages with conflicts" and then "Skip 27 Packages".
qpid-cpp was rebuilt last week to use the new Boost: http://koji.fedoraproject.org/koji/buildinfo?buildID=711764 If there are conflicts then it's because something else can't be upgraded because it still needs the old boost, in which case the "something else" needs to be rebuilt in rawhide.
I've just cleanly installed boost and qpid-cpp on a fresh rawhide installation, so the problem is definitely not with either of those packages, but something else that depends on Boost. I don't know how to get DNF to tell you what the problem is, it's quite annoying like that.
You could try --best --allowerasing and see which packages it attempts to erase. It will be one of the packages listed at: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/QAQZTHXSTXS4VWCO3SH7BCEY5QYDMCB5/ The bug should be reported against that package, so the maintainer fixes the build failure and rebuilds it.
Whatever it was, the issue seems to have been resolved between yesterday and today because I can now upgrade. Thanks to mystery packager!
