A-EON Technology is not affiliated to the "ExecSG" team as Trevor has pointed out.

The private branch of the firmware is used for testing and developing the ExecSG projects and has nothing to do with the consumer release of the firmware.

The official X5000 firmware that is distributed on X5000 systems and board is the version that BigFoot has worked on for A-EON over some years.

He is the official maintainer of the firmware for A-EON. A-EON is happy for this relationship to continue going forward and presumably BigFoot is too (his schedule permitting).
