Ah, ok, thanks.
So it should never be any big deal automatically upgrading to a new image.
The old config should always work?
I guess it could always be so bad that it looks like the old config works, but for some reason some firewall rule or something important like that doesn't work as it should....oh well, I dont think I dare upgrade
EDIT: Or well, this doesn't sound very good either...dont really know what it means, but sounds bad. Maybe safer to update anyway
WAN IP ain't static so could theoretically change anytime for me.
"fixed a long standing bug with regenerating firewall rules (including automatically generated ones) that reference the WAN interface when the WAN IP address changes"
