v7.6.0 will have a full mobile friendly template which uses an adaptive design; you can test this out now at UBBDev. v7.6.0 has a projected release date of this summer; we've been working diligently on redesigning key areas and restructuring them for a more modern feel.
The latest build of the v7.6.0 version will always be run at UBBDev as it's our public testing platform. You can view all of our checkins in the
Official UBB.threads Announcements forum.
At a later date I will be offering some sort of Mobile Template adjustments for versions prior to v7.6.0, for sites which aren't ready to, or don't want to, upgrade to the new build.
