v0.5.0

• There is now a macOS build, for both Apple Silicon and Intel Macs, as a disk image you can download and drag to your Applications folder.
• The app is not signed with an Apple developer certificate, so the first time you open it macOS will refuse. Right-click the app and choose Open, and it will ask once and then remember.
• Two things had been quietly stopping the Mac build from ever finishing. The build machine tried to publish the app itself and gave up when it had no permission to, and the Apple Silicon version was left without the signature that Macs require before they will run anything at all.
