- 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.
- The specs index no longer carries a table mapping the three original spec names to the renumbered ones, and spec headers no longer record a feature branch or "first written as" name.
- A task that pointed at research under the old 001 directory now points at its current path, so every reference resolves to a spec that exists.
- The constitution's 1.4.1 amendment still records that the specs were split and renumbered, without listing the retired names.
- App Store Connect refused the package with error 91109 because the embedded provisioning profile kept the com.apple.quarantine attribute the browser set when it was downloaded.
- Every extended attribute is now cleared from the app before it is signed, so no file copied into the bundle can carry quarantine into the package; com.apple.provenance, which macOS sets on every file and which cannot be cleared, remains.
- The App Store variant was only signed ad hoc to run locally, so nothing it produced could be submitted; with a Mac App Store Connect provisioning profile in .signing/app-store.provisionprofile it now embeds the profile, adds the profile's App ID and team to the app's entitlements, signs both executables with the keychain's Apple Distribution identity, and wraps the app in an installer package signed with Mac Installer Distribution.
- A profile whose App ID is not the bundle's is refused, and a missing distribution or installer certificate stops the build rather than producing an unsubmittable package.
- CFBundleVersion becomes the build's UTC time to the minute, since App Store Connect rejects a build number it has seen, while CFBundleShortVersionString stays VERSION; ITSAppUsesNonExemptEncryption is false, as the build's only cryptography is hashing and random numbers.
- The bundled daemon keeps only the sandbox and inherit entitlements, which a helper inheriting its parent's sandbox requires.
- Without a profile the variant builds as before, ad hoc or with MIDI_HARBOR_SIGNING_IDENTITY, to run on the building Mac.
