What is this about? There continues to be no use of DT on x86, so without 
context
this feels pretty much meaningless to me.

Sure, but what practical use does this have for anyone using Xen?

Hmm, MiniOS isn't an integral part of a Xen release, so I wonder if such really
belongs here. Yes, I also understand that there's not really anywhere else to
put such.

I decided to put it here since we include information about stubdoms 
in|CHANGELOG.md|,
and MiniOS is related to that.

Stubdom code is part of the git repo and hence the tarball. MiniOS isn't.

Right. The kexec support in Mini-OS was primarily added in order to support
PVH xenstore-stubdom live update. This has already been added to the changelog,
so there is no real reason to mention the Mini-OS change here as well.
