This is the image now active.

Is it buggy ? Or should I leave it as is ? I have also a backup from the image it was delivered with.

What image is recommended by the users ?
I have
Antminer-R4-all-201612020035-autofreq-user.tar.gz

and the all new
Antminer-R4-all-201704280718-autofreq-user-Update2UBI-NF.tar.gz

Which is the better choice ?
