It is generally hard to say. A few bits and pieces are changing but nothing really substantial. It is very possible that your custom would just continue to work as it does right now. You could backup your `/etc/pihole` somewhere and then try the upgrade. If you cannot make it work, you can easily stop everything, restore `/etc/pihole` from your backup and go back to `master` with all components.

One major difference is that content in `/etc/dnsmasq.d` will not be loaded anymore by default - on one hand to prevent incompatibilities during upgrade but actually because there are still applications installing custom `dnsmasq` configuration that conflicts with stuff that is already present (remember the famous `lxc.conf`...). You can switch on importing custom config files through the config by setting

```auto
misc.etc_dnsmasq_d = true

```

either in `/etc/pihole/pihole.toml` or by simply running

```auto
sudo pihole-FTL --config misc.etc_dnsmasq_d true

```
