Tested:

• Backtickle_0.2.0_amd64.AppImage from release v0.2.0

Compatibility: not self-contained: uses the C library of the system; references glibc 2.35

Warnings:

• The AppImage contains no update information, so users cannot update it with AppImageUpdate or similar tools. Please consider embedding it when building the AppImage (e.g., appimagetool -u) and publishing the .zsync file next to the AppImage; see https://docs.appimage.org/packaging-guide/optional/updates.html
