I changed over months and months ago to v2. It was painful, but docs were being written at the time, and the community was able to help me with most of my problems. The one last problem I've not solved yet is having caddy 2 work with bitwarden whereby bitwarden's ssl does not conflict with caddy 2. I was unable to figure out how to work with it, so my bitwarden ssl expires every month or two and I have to manually update the ssl by bringing down my personal site for a couple of minutes.
