+# v29.0
+
+This release has been tracked in our [roadmap
+project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration
+v29.0. 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. This was originally used for
+  supporting huge pages or shared memory backing which is now natively supported
+  (#5085)
