Thanks @JGPSHNTAP. I stumbled across D releases somewhat. I routinely just change the URL of the current P release of different software packages to see if a new P release is there. Once I tried doing the same with D releases and was surprised to see that they are all there as well.
I would love to know when P2 is coming out. As I said I'd prefer to do that version anyway. I'm hoping this will be the last round of 7-mode upgrades I ever do. These are for six 2220s in remote offices that we've not transitioned to cdot yet.
