It is meant to address a few issues, I know the bold ones are ones that many of you have experienced.
PPTP VPN Protocol
Guide information missing occasionally
Occasional errors deleting >35 shows on the DVR
Better support for Sprint Airave devices
Buffer updating when shows are paused
Also, there's a few performance and stability upgrades that should help overall.
