The 5.0.1 image is now available for Shamu and Occam.
Bear in mind that the batch file included is still broken as it will give you a "system.img not found" error.
Not to worry, just do it the old fashioned way with fastboot.
Or, if you like a small challenge, just edit the batch file to flash the boot, recovery and system images instead of the update script.
I took it a step further and had it boot into twrp when it was done so I can reflash SuperSU.
if there is interest, I can post up a link to my batch file.....
