I was going to ask you about this as I saw the RPi 2 announcement today. I figured you probably already had one :)
I haven’t been building the ARMv7 VMs recently since there is something broken in the ARM fast BitBlt enhancements for ARMv7, which I haven’t had time to look into. Have you been able to make any improvements to that? (There’s also some potential issues noted by Ken Dickey regarding atomic operations).
