I finally heard back from vBox this morning:

It looks like a few of you guys already got the firmware from them. There’s a second version for other models that should fix the remainder of everyone.
Again, my apologies for this not being ready for all of you out the gate. We had expected them to release the firmware when they announced the support for Plex.
