v50.1 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)
