- A Wayland desktop finds a window's icon by looking up its application ID among the installed desktop entries. An AppImage carries its entry and icon inside its own tree, where no desktop looks, so its window showed the generic Wayland icon and Midi Harbor was missing from the application menu.
- Run from an AppImage, the window now installs com.mrgeckosmedia.MidiHarbor.desktop under $XDG_DATA_HOME/applications and the icon under icons/hicolor/scalable/apps before it opens. Exec is rewritten to the AppImage file, quoted as the Desktop Entry Specification requires, and each file is written only when it differs, so a moved AppImage is followed.
- TryExec names the AppImage file, so desktops stop offering the entry once the file is deleted, which is how an AppImage is removed.
- Nothing is installed when a directory in XDG_DATA_DIRS already holds the entry: one under the user's directory takes precedence and would point a package's menu item at the AppImage.
- 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.
