loaded 10_RC3_V2 I did run into one minor issue:
Now upon boot rather than it finishing with the typical locked screen it instead is going to blank black screen. You then have to hit the power button twice to bring up the normal lock screen. Its not a issue where the screen is being turned off as the hard button shortcuts are all still lit below the screen. You are basically having to do a screen refresh. Power once to turn off the screen and then again to bring it up properly.
Once you do this everything on my initial brief overview seems fine. I like the new boot animation much better. Very nice.
Tinkered with it some. It boots normally without the blank screen if its unplugged. When plugged into the PC it has the blank screen issue. I will try it with just going to a power recpticle
