in github there is a new release of the sonar-scanner-cli, version 6.2.0.4578, but on the SonarScanner CLI page there is only the older version available, version 6.1.0.4477
Thanks for the ping. We have an internal release process separate from the technical release that includes, among other things, updating GitHub - SonarSource/sonar-update-center-properties which drives that frame in the docs. It will come along soon enough.
