Update Check
Our Suite brings an update check. It runs twice per day and reaches out to an end point at our public Website.
On-Premises Offering
The update check applies to the on-premise versions of the Suite and once there is a new version available for download, you will see an update icon next to the Suite version in the administration view.

If you click on the icon, a manual download of the new version starts in your browser. After it completed, follow the steps at Software Updates and Upgrade to upgrade to this new version.
Azure Offering
Our AKS offering is maintained in similar cycles and the update symbol should be interpreted as a hint to check if a new version is available. Also here, follow the steps at Software Updates and Upgrade .
