The most recent update upgrades openfortivpn from 1.9.8 to 1.17.1. After this update, network-manager-fortisslvpn does not update DNS server settings when connecting to the VPN server. I checked the content of /etc/resolv.conf before and after connecting to the VPN server, and their contents are identical. This bug caused named name resolution on my VPN connection to fail.
Verified fix: include this patch
