+This is a point release containing security fixes and bug fixes.
+
+Security Fixes
+--------------
+
+This release fixes a security vulnerability in disk image handling.
+Details can be found in [GHSA-jmr4-g2hv-mjj6](https://github.com/cloud-hypervisor/cloud-hypervisor/security/advisories/GHSA-jmr4-g2hv-mjj6).
+
+* A new `backing_files=on|off` option has been added to `--disk` to
+  explicitly control whether QCOW2 backing files are permitted. This
+  defaults to `off` to prevent the loading of backing files entirely.
+  (#7685)
+* Explicit image type specification via the user interface, removing
+  reliance on format autodetection (#7728).
+* Prevent sector-zero writes for autodetected raw images (#7728).
+
+Bug Fixes
+---------
+
+* Fix various inconsistencies in our OpenAPI specification file
+  (#7716, #7726)
+* Fix QCOW2 thread safety for multiple virtio queues
+  (`num_queues > 1`) (#7661)
