When I synced my Zune HDs today, I got an alert about updating to a new device firmware version, 4.3. (The previous version was 4.1.) No word on what's changed, if anything, and I don't see anything about it online yet. Anyone?

Update: Microsoft later documented the update:
Today we released the v4.3 firmware update for Zune HD players; this update adds support for upcoming 3d games and applications, as well as an auto-suggest feature for better text input, and other minor improvements. Enjoy!
