Re: [knot-dns-users] Zone breaks after update to 2.8.0

Hi Daniel Thanks, that fixed it. I see, it is not really recommended to blindly update knot as you can easily break your zones and sometimes also have to do manual work before updating. I heard also from other people that updating broke some of their stuff, so maybe that's something to keep an eye on for you guys ;) . However, great work with the part that works fine!
