The following user visible changes have been made: + +### Release Binary Supports Both MSHV and KVM + +On `x86-64` the binary included in releases supports both the KVM and MSHV +hypervisor with runtime detection to identify the correct hypervisor to use. + +### Snapshot/Restore and Live Migration Improvements + +Improvements have been made to the data structures used for both live migration +and snapshot/restore. Unfortunately this has broken compatibility with older +versions (support for migrating between major versions is not yet officially +supported but has worked for some versions.) + +### Heap Allocation Improvements + +Improvements have been made to the volume of heap allocations when running with +`virtio-block` devices along with a reduction in the peak heap size. + +### `ch-remote` Improvements + +Support for "pinging" the VMM and shutting the VMM down have been added to +`ch-remote`. + +### `AArch64` Documentation Integration + +The documentation for `AArch64` support has been integrated into the main +README. + +### `virtio-block` Counters Enhancement + +The counters for the `virtio-block` device has extended to include min/mean/max +latency counters. + +### TCP Offload Control + +The `virtio-net` device has gained support for controlling the enabling of +checksum and offloading. This allows the device to be used in environments +where the hardware lacks support for the offloading. + +### Notable Bug Fixes + +* Update dependencies including a version of `linux-loader` that addresses an + infinite loop issue ([details](https://github.com/rust-vmm/linux-loader/security/advisories/GHSA-52h2-m2cf-9jh6)) +* Fix bugs related to `virtio-net` including an integer overflow issue + (#4924, #4949) +* Use host `cpuid` information for L2 cache for older KVM on x86 (#4920) +* Memory mapped into the guest is now marked as non-dumpable which prevents large core files (#5016) +* Fix QCOW2 refcount table size (#5034) +* Fix unpause support on MSHV in dual binary (#5037) +* Threads inside `virtio` devices are now shutdown on reboot (#5095) + +### Removals + +No functionality has been removed in this release. + +### Deprecations + +* Support for specifying a directory with `MemoryZoneConfig::file` or + `MemoryConfig::file` has been deprecated.
