+
+            ## Highlights
+
+            ### New Pro Licensing Architecture
+            - Server-backed license activation
+            - Device-bound activations
+            - Activation limits enforcement
+            - Cryptographically signed licenses (Ed25519)
+            - Secure offline-aware entitlement validation
+            - Beta / Pro plan infrastructure
+
+            ### Operational Improvements
+            - Better AI troubleshooting context handling
+            - Improved system analysis consistency
+            - More reliable operational recommendations
+            - Reduced hallucinations in infra workflows
+            - Stronger baseline and drift awareness
+
+            ### Security
+            - Hardened licensing flow
+            - Secure device identity persistence
+            - Improved CSP configuration
+            - Better Electron isolation boundaries
+            - Safer IPC communication paths
+
+            ### Packaging
+            Automatic builds are now generated directly from GitHub Actions.
+
+            Included artifacts:
+            - Linux AppImage
+            - Linux DEB
+            - Linux RPM
+            - Windows NSIS installer
+            - Windows portable executable
+
+            ---
+
+            ## Notes
+
+            This is still a beta-stage release intended for testing and feedback.
+
+            The licensing backend infrastructure is intentionally not part of the public repository.
+
+            If you encounter issues, please open a GitHub issue including:
+            - operating system
+            - SysAI version
+            - logs/screenshots
+            - reproduction steps
