That's the shit! Thanks for improving the audio!
Sounds like my bitching about unencrypted discovery queries on github some time ago actually worked. I'm really happy to hear about the different improvements regarding discovery!
One tiny thing: for me it was easy to follow, but I'm a rather technical person. So maybe you could try to explain some things in a bit more detail. For example you only said v4 and v6 for IPv4 and IPv6.
Of course one has to have some knowledge how software & networks in general and syncthing in particular works to understand all of it. But maybe this helps some users to understand more of the details.
Nice house btw
