8B has been released in version v0.2.1.
The Rust-based tool creates and edits controller profiles for 8BitDo devices (currently the 8BitDo Pro 3) directly over USB on Linux, including button mapping, sticks, triggers and macros.
The new version brings changes to the Flatpak, which now receives automatic updates via a signed remote.
