They (Vera) should just update the OS apps + libs with every Firmware, and in case of UI5 at least provide an instruction for these kinds of updates to do it yourself.
Could not agree more... On my Veralite the OpenWRT under the hood of firmware 1.7.760 is still version 10.03.1 (backfire) that is more than three years old and 3 major revisions behind !!!
I think (though I do not own one so it would be good for somebody who does to confirm) that Vera has upgraded a few times OpenWRT for the Vera Edge... Why not VeraLite (and I suspect Vera 3 as well) ?
