Saw this version in the stream seemingly for all the Genies early this morning apparently as part of a new staggered NR roll out and forced the update on my HR34 mostly out of curiosity.
Though my guide scrolling was rather sluggish on 0x0740, and HD Apps are still largely mired in mud, but improving.
Don't know what it does or supposedly fixes yet, though everything seems fine so far.
Perhaps the Mods. can post an issues thread for this one since it appears to on its way to all the Genies.
