+Release note
+============
+QLS 3.6.0 release is a feature release.
+It adds new following features:
+  - Local Report Storage: Keep local copies of license usage reports for easier access and backup.
+  - Optimized Performance for Floating Licenses: High-concurrency license usage is now handled more efficiently, improving performance under heavy loads.
+  - Email Notifications for Lost Connections: Configure an SMTP server with On-Prem Server to automatically send notifications when the connection to the Qt Cloud is lost
+  - Interactive License Registration: Prompt for credentials interactively if not provided and warn when insecure (HTTP) connections are used.
+  - Enhanced Offline License Usage Reports: Reports now include Consumer auxiliary info and Name fields and exported reports cover all record types.
+  - New REST API Endpoints: Query current license pool utilization and active users for easier integration with external systems.
+  - IPv6 Support: Local TCP connections between client applications and Qt License Service now support IPv6.
+  - Log File Rotation: Limit log file size automatically, new log files are created when the maximum size is reached
+  - Automatic Qt Account Login Renewal: Automatically refreshes Qt Account credentials with a configurable renewal interval.
+  - Error Reporting for License Reservation Failures: Qt License Service provides clearer diagnostics when license reservations fail.
+  - Telemetry Configuration via CLI: Update telemetry preferences directly through the Qt License Service command-line interface.
+
+
+Release also maintains backward compatibility (source and binary; 'server version' >= 'daemon version' >= 'client api library version')
+with QLS 3.x.x series.
