My STBs as of earlier this week are showing a new TV2 Client version and UI version:

TV2 Client: 2.1.2295.10

UI: 5.4.4

Previously for phase 3 we had seen two other TV2 Client versions: 2.0.26496.12 and 2.0.26496.15.

I'm not sure what this new version does, I have not been able to find anything in the interface that seems different than before.  I suspect it may fix the "Exit to TV" issue, and/or may also have more support for the new U-Verse Enabled Applications on channel 9301.

hpmsrm stated he received this update a few days ago, but I don't think anyone observed the fact that this update is in fact newer than either of the 2.0.x releases.

If anyone notices any new behavior, please post it here.
