The last I looked, one of the Adobe staff has uploaded a replacement SDK ( for Windows / Mac ) to a specific download location which people can use at their own risk to get things published.
There were a couple other tweaks I believe including specifying minimum OS ... I had one of my team here looking into it as we had an app update to publish. We are pretty much closed here for the day.... When he's back in tomorrow ( 9 am BST ).. I'll have him do a quick list of steps to apply ( and anything to watch out for ) and post them up here. J :)
