+<p><strong>July 23, 2025</strong>: We've been made aware that some customers are receiving group names with a mysterious suffix, such as <code>provisioning</code>. Since these groups or profiles with these names don't exist in Admin Console (they were a historic construct from a previous iteration of the Adobe platform), we will ensure that we fully filter out these mystery group names. APIs that return lists of group names will be changed to return <strong>only</strong> user group and product profile names that really exist in the org.</p>

+<p>This change will come into effect on <em><strong>August 26, 2025</strong></em>.</p>
