The ncv(4), nsp(4), and stg(4) drivers are now removed from DragonFly.  So is the portal file system.   Also, though not a removal, vm.swapcache.use_chflags now defaults to 0.  Does this affect you?  Almost certainly not!  I feel compelled to point it out, though, just in case there’s that one person who didn’t want a surprise.
