After a long hiatus, Gugal 0.8.2 is finally out, with a fix for an issue where searx instances without HTTPS support wouldn't work.
It also brings a number of minor improvements. Finally, Gugal is now available in Italian and Spanish.
The F-Droid version is expected to be updated soon, and the direct version is now available: https://gitlab.com/narektor/gugal/-/releases/0.8.2-n
