Update went fine on a bare metal install. Customising the webUI port is a little easier now, instead of editing lighttdp.conf I think you can do it in the UI.

I struggled to find some settings, I looked for ages for the API token. Found it in all settings: expert scroll for half a mile down the webUI API section.

I have an lxc and docker container to go.

Also, struggled with adding CNAMES in bulk, I thought you could do that in the old UI. You might be able to in the new UI. I just 'one by one’d them.
