I design QLog so that the user does not have to solve these things. QLog regularly, every 7 days, checks if there is any update in the lists on Github (https://github.com/foldynl/hamradio-membeship-lists). If there is a change, new lists are downloaded automatically when QLog is started. The Github repo is also updated once every 7 days, always on Wednesday morning.
Everything is updated automatically, but many Clubs publish data without any timestamp information , so it is not possible to find the latest update directly at the source.
