I have applied the update to Pi-Hole and found that is was not working. Then I found the update notice for dnsmasq on your website. But when I applied it (successfully) I did not notice any improvement on my Desktop.
This is my config (OpenhabianPi on a RaspberryPi):
Raspbian GNU/Linux 8 (jessie)
## Kernel = Linux 4.9.35-v7+
## Platform = Raspberry Pi 3 Model B Rev 1.2
