At https://imagej.net/learn/launcher#download there are links to download the "latest UNSTABLE" launcher executables. But they are wrong: when I downloaded ImageJ-linux64, I get imagej-launcher-5.0.4-20200905.044936-26-linux64.exe, but the last imagej-launcher release was 6.0.2, and there are also 6.0.3-SNAPSHOT snapshots deployed. So the Maven metadata is incorrect, and these download links are not useful.
