- Releases now include Midi-Harbor-<version>-<x86_64|aarch64>.AppImage, built from the same binary as the packages and listed in checksums.txt, for distributions without a .deb or .rpm. Opened with no arguments it shows the window, and the daemon it registers runs under the systemd user unit like a package install.
- service install run from an AppImage registers the .AppImage file instead of the executable inside the runtime's temporary mount, which is gone once the process exits. The file is used only when the running executable is inside APPDIR, so a program started from another AppImage, whose APPIMAGE it inherits, still registers itself.
- The AppImage carries only the Avahi client libraries from the Debian 12 sysroot, with their LGPL-2.1 license, found through the binary's RUNPATH rather than LD_LIBRARY_PATH; glibc 2.35 or newer, ALSA, D-Bus and libxkbcommon come from the host, as for the packages.
- Its AppRun starts the binary as midi-harbor, so on X11 the window's class matches the desktop entry instead of the AppImage's file name.
- Building it needs the cross image's new patchelf, file, appimagetool 1.9.1 and type2 runtime 20251108, pinned by checksum, and a sysroot rebuilt to carry Avahi's license; the script stops and names make build-sysroot when that license is missing.
- The window never had a title, so taskbars and window lists showed it as untitled on every Linux desktop; it is now titled "Midi Harbor". The header draws its own title, which is why it went unnoticed.
- On X11 the window's class comes from argv[0], because the pinned libcosmic replaces its X11 window attributes with its Wayland ones. The desktop entry's StartupWMClass is now midi-harbor, the class a package install gets, so X11 taskbars match the window to its entry and icon; Wayland still pairs by the application ID.
