I was one of the people hammered by 0.13.x on my Antsle (worked ok on my Edgelinux homebuilt). My understanding was 0.13.x had security fixes that 0.12.x which with the help of the support team my Antsle was restored to doesn't have.
Just curious where things stand?
Has an understanding of what went wrong been reached? In my case it seemed like it was triggered by a disk space problem. The system simply ran out of disk to work with during the upgrade.
