Flatpak 1.8 is packed with lots of new features and improvements. Among the most important ones, there’s simplified installation of OSTree P2P (Peer-to-Peer) support, which obsoletes installation of apps from local network peers and no longer allows automatic sideloading of apps from a local USB stick. To enable sideloading, users will have to configure a sideload repository by creating a symlink to it from /var/lib/flatpak/sideload-repos or /run/flatpak/sideload-repos. Moreover, Flatpak 1.8 ships with a systemd unit, which isn’t installed by default, to automatically detect plugged in USB sticks with sideload repositories.
