Just updated my Touch to the new firmware, with no apparent problems.
I was hoping that the "Improved recognition of page-turn taps" line might help resolve an issue I have on my unit, but it hasn't. Sadly, the Library navigator bar at the bottom remains intransigent. Anything past page 1 in my Library remains inaccessible, since the bar doesn't respond to touch.
Oh, and I honestly, really could not care LESS about being able to tell people on Facebook what I'm reading, let alone use my Kobo to do it. What a waste of development time and effort when other features are still pending.
