Wait, ISO standards have numbers, but ISO 18 isn't a real international standard. ISO 18 could be a typo or a specific standard not widely known. Some industries have their own standards under ISO, like ISO 18000 for supply chain. Maybe the user meant ISO 18 as a version of firmware or software compliance? Or maybe they're mixing up terms. The ISO part could also refer to an ISO file, like a disk image. That's common for software distributions, so maybe it's about releasing a version 1.2.6 of Beini software as an ISO file, version 18.
