+---
+This release has been tracked in our [roadmap
+project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration
+v43.0. The following user visible changes have been made:
+
+### Live Migration over TCP Connections
+
+Support has been added to enable direct live migration from two hosts via TCP
+connections. This supplements the existing support for migrating over a UNIX
+socket which can then be tunnelled as desired. The documentation has been
+updated. (#6850)
+
+### Notable Performance Improvements
+
+The `VIRTIO_RING_F_INDIRECT_DESC` feature has been enabled for `virtio-block`
+devices. This significantly increases the throughput of the devices with a
+small negative impact on latency. (#6826)
+
+### Notable Bug Fixes
+
+* Cloud Hypervisor now accepts VFIO devices that use I/O PCI BARs on non x86-64
+  architectures. Whether they function depends on the host PCI host bridge
+  support - previously they would be rejected even if the driver did not use
+  these BARs. (#6871)
+* Command line groups were adjusted to ensure that at least one payload
+  parameter was provided if any other VM parameters provided. (#6832)
