The developers just commented in another thread that 4.7.1 has been re-engineered to support FOG 1.2.0 for those that can’t migrate to 1.3.0 right now. You won’t get support for Win10, gpt disk format, NVMe disks, or the 1000s of improvements in 1.3.0 over 1.2.0, but you will get the latest sata and nic support with 4.7.1
