I previously posted a writeup based on Arch Wiki instructions, and upon updating to 3.5.5 this no longer works.

The config file still exists, but mDNS will not operate.

I’ve managed to enable the avahi-daemon.service unit file and this validly now registers the interface link to mDNS per the avahi log, but systemd-resolve still shows it as unsupported (i.e., -mDNS listed with the wlan0 link).

It appears that the Arch Wiki now redirects mdns to the Avahi page, and has instructions for enabling Avahi. However, it previously linked to systemd-resolve for instructions including NetworkManager as well - clearly this changed (yes the wiki entry still exists), and the configuration I had previously (also explained in the Arch Wiki) does not work. But I can’t find any reasoning behind this. It’s also clear that NetworkManager is still being used by the system, but this
