This morning I had new FW on two of my Cisco 1520s, the new FW is STA1.0.0_1520_LR_F.1601
Just what it fixes, I haven't found out yet and it isn't on all of my TAs yet either. Looks like it was a download feed last night since there was also a reboot involved and only 3AM channel maps appear.
This is on TWC in LA County North (Valley West, Los Angeles).

I encouraged my STA-1520s to download an update last night and this morning. No joy. Seems that Cox in Phoenix isn't distributing it yet. I'm still on '1402'.
