Starting with Frontman version 1.6.0 an auto-update has been introduced and enabled by default. Unless you have disabled it, you don't need to take any action.

After the download is finished just double-click the MSI file and install it. The software detects the older version and performs an update preserving all your settings.

With frontman 1.8.0 the method of how frontman gets super privileges to execute ICMP echo requests (pings) has changed to guarantee compatibility with the latest Linux Kernels. File capabilities based on libcap are now used instead of kernel parameters added to the sysctl. The DEB and RPM packages will migrate everything but you are well-advised to check it out quickly.

This command must confirm the frontman binary has the capability
cap_net_raw+ep If not, execute
sudo setcap cap_net_raw+ep /usr/bin/frontman
