dev-libs/libxmlb-0.2.0 has been pushed to portage. The NEWS file of that release contains the following information: Important: - This release breaks API and ABI and bumps the version of libxmlb.so and so packages that depend on this library (e.g. fwupd or gnome-software) will need to be rebuilt at the same time. So I've added a sub-slot to the package starting with 0.2.0 version. I suppose gnome-extra/gnome-software should either make use of the sub-slot dep or limit dependency to <0.2.0 versions.
