Most notable change in the set is cdemu being (finally) ported to introspection, just like gcdemu has been awhile ago. vhba only got doc changes, AFAICT. Minor bugfixes in the rest.
currently, the latest upstream versions are: app-cdr/cdemu-3.0.3 app-cdr/cdemu-daemon-3.0.5 app-cdr/gcdemu-3.0.2 dev-libs/libmirage-3.0.5 bug for vhba version bump to 20161009 is #618286
...actually, it's app-cdr/cdemu-3.0.4 and app-cdr/gcdemu-3.0.3, even if the only change between these and their immediate predecessors are translation string changes.
Note that upstream has changed libmirage API again, and failed to bump SONAME: https://sourceforge.net/p/cdemu/bugs/106/ So if we're going to go for this release, we need a custom Gentoo SONAME to avoid breaking stuff.
Bumped all of 'em to 3.1.0.
