- 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.
- A daemon keeps running the copy it was started from, so after an update the old one ran until the next login and nothing said so; clients compared only the major protocol version. Every build now carries a UUID, the daemon reports it as ServerInfo.build_id under protocol 1.3, and a daemon too old to report one counts as outdated.
- The window shows a notice above every page when the daemon it reached is another build, with both versions. Update now registers the copy that was opened as the service and restarts the daemon from it; Not now puts the notice away. Nothing is restarted unless the user asks, so two copies open at once cannot replace each other's daemon in turn. A newer daemon is offered as Use this version, and one the service did not start, or one reached with --socket, gets no button.
- service install --start now stops a running daemon before registering and starting, so the daemon started is the program that was asked. Under systemd and Task Scheduler it used to rewrite the registration and leave the old daemon running, since starting a running service does nothing.
- service status says when the daemon is another build than the program asked, and --json carries same_build.
- The App Store app stops a daemon another build of the app left running and starts its own, instead of attaching to it.
- Packaging sets MIDI_HARBOR_BUILD_ID once for everything a run builds, because the App Store app, its helper and each architecture are compiled separately and must agree. Packages of one release share an identifier, so neither replaces the other's daemon.
- A network port kept a machine it had connected to after the connection was removed, listed it as on the network whenever its host advertised any session, and could not connect to it again: Connect resolved identifiers only among advertised sessions and failed with "no peer named". A machine remembered only for a connection is now dropped once no network port uses it, an untrusted machine is marked present only by a session at its exact address, and Connect resolves remembered machines by identifier or name.
- A network port invited the one address it had connected to until it answered, so a session that came back on another port was never reached. The session name advertised at a machine's address is now stored as advertised_as in the configuration, and while the link is down the port connects where that session is advertised and stores the new address. A machine carrying MIDI is never moved.
- Each daemon now holds an Ed25519 key in identity.key beside the configuration and publishes mhkey and mhport in every session's TXT record. Two packets on the control port, a challenge and a signed proof, let a network port prove which port of which daemon it is. A machine stored with a proved key and port_id is followed under any name and to another host, with its trust, and a port deleted and made again is not followed. The challenge is sent only to a session that advertises a key, so no other RTP-MIDI implementation receives it.
- A machine with no key is followed by name to a new port on its host, and to another host only when it is not trusted, since an advertisement proves nothing and trust is held by host.
- An invitation over an IPv6 link-local address was never answered, because the sender's address was kept without its scope. Apple's Network MIDI invites that way and reported that the port did not respond. The address is now kept whole for the control and data ports.
- Adds ed25519-dalek and hex. The packet fuzz target reads the new packets.
- The interface moves from 87ab8179 to libcosmic master of 2026-09-24, which brings its newer winit and accesskit forks and upstream's menu, context-menu and maximized-window fixes.
- The accesskit_winit build failure newer libcosmic has on Windows does not reach this build: macOS and Windows disable libcosmic's default features, a11y with them, so no accesskit crate compiles there. Enabling a11y on Windows would need a patched accesskit, as the pin's comment notes.
- The lock keeps gpu-allocator on windows 0.62.2, the version wgpu-hal 28.0.1 passes it; the update had re-resolved it to an older windows, breaking the Windows build with mismatched Direct3D types, and a later cargo update can do so again.
- 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.
- The systemd user unit now has an ExecStop that sends SIGTERM to the main process and waits for it to exit; only then does systemd signal whatever else remains in the unit.
- By default systemd signalled every process in the unit at once. Run from an AppImage, that included the runtime serving the daemon's executable, which unmounted while the daemon was still shutting down: every stop and logout ended in SIGBUS and a core dump before held notes were released.
- A daemon installed from a package is alone in its unit and stops as before. Existing registrations gain the ExecStop when service install is run again.
