The old release is not going anywhere, users can pin it in their build plans. If someone really needs backward compatibility, they can fork `old-binary` and keep using it indefinitely long. (Or you can publish such fork yourself, if you want to be extra nice)\n\nNot being able to roundtrip NaN is a cardinal sin for `instance Binary Double`, it must be rectified.",
