The latest version 1.4.7.5 for CONTROLA it is a failure.
If you want to edit / delete a pool the system frozen, and you must to unplug to power cable form the ASIC and the PI in order to start again.
The version v1.4.6.5.1 works fine !
I would have to disagree - I have never had to power off my power cable.
I may have to reboot once in a while after switching pools, but I do that via SSH and I'm fine.
