Every 8 hour, KNM checks if there's a new build available. You can force this check by typing "version -check" in the System administrator console that you find in the K menu. KNM will then notify you if there's a version available in the botton right corner as the picture shows. If you click on that link, or select "Check for new version", you will see a page looking like in the screenshot below with links to both the installer and the release notes. Unfortunately, the new version I promised in my previous response has been postponed. You will get notified in the KNM interface when it is available.
