+    "summary": "* Fixed \"Run a scan now\" occasionally not returning to the Scanner page after starting a scan.\n* Scan errors (for example, a scan already in progress) are now shown clearly instead of the\n  button silently doing nothing.\n* Improved the reliability of scheduled protection tasks (scans, threat intelligence updates,\n  and firewall enforcement) so they keep running even in unusual hosting situations.",
