v49.0 This release has been tracked in [v49.0 group](https://github.com/orgs/cloud-hypervisor/projects/6/views/4?filterQuery=release%3A%22Release+49%22) of our [roadmap project](https://github.com/orgs/cloud-hypervisor/projects/6/). MSHV Support Improvements ------------------------- On AArch64 with MSHV, firmware boot (#7391) and graceful guest shutdown (#7354) are now supported, and CI coverage has been added (#7381). Logging Improvements -------------------- Logs now use an improved timestamp format (#7355), emit an explicit message on graceful shutdown (#7346), and reduce noisy warnings with newer guest kernels (#7423). Removed Default IP and Mask for `virtio-net` Devices ---------------------------------------------------- The implicit default IP (192.168.249.1) and netmask (255.255.255.0) for `virtio-net` devices have been removed, as previously announced in the deprecation notice two releases ago (#7365). Users now can create `virtio-net` devices with no IP and netmask assigned. Notable Bug Fixes ----------------- * Prevent crash on malformed vsock connect requests (#7310) * Fix vCPU hotplug when the vCPU count exceeds 255 (#7349) * Drop the VFIO container when no VFIO devices are active (#7364) * Gracefully close preserved file descriptors on hot device removal (#7371) * Fix race condition in pause–resume cycles (#7397) * Add NetConfig offload parameters to the OpenAPI spec file (#7445) * Fix seccomp filter violation from the http-server thread (#7454) Contributors ------------ Many thanks to everyone who has contributed to our release: * Aastha Rawat <aastharawat@microsoft.com> * Alyssa Ross <hi@alyssa.is> * Anirudh Rayabharam <anrayabh@microsoft.com> * Ariel Chenet <apchenet@gmail.com> * Bo Chen <bchen@crusoe.ai> * Can Zhang <icloud9957@gmail.com> * Eugene Korenevsky <ekorenevsky@aliyun.com> * Maximilian Güntner <code@mguentner.de> * Muminul Islam <muislam@microsoft.com> * Oliver Anderson <oliver.anderson@cyberus-technology.de> * Philipp Schuster <philipp.schuster@cyberus-technology.de> * Rob Bradford <rbradford@rivosinc.com> * Ruoqing He <heruoqing@iscas.ac.cn> * Wei Liu <liuwe@microsoft.com> * Yi Wang <foxywang@tencent.com>
