+# v0.5.0
+
+This release has been tracked through the [0.5.0 project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/6).
+
+Highlights for `cloud-hypervisor` version 0.5.0 include:
+
+### Virtual Machine Dynamic Resizing
+
+With 0.4.0 we added support for CPU hot plug, and 0.5.0 adds CPU hot unplug and
+memory hot plug as well. This allows to dynamically resize Cloud Hypervisor
+guests which is needed for e.g. Kubernetes related use cases.
+The memory hot plug implementation is based on the same framework as the CPU hot
+plug/unplug one, i.e. hardware-reduced ACPI notifications to the guest.
+
+Next on our VM resizing roadmap is the PCI devices hotplug feature.
+
+### Multi-Queue, Multi-Threaded Paravirtualization
+
+We enhanced our virtio networking and block support by having both devices use
+multiple I/O queues handled by multiple threads. This improves our default
+paravirtualized networking and block devices throughput.
+
+### New Interrupt Management Framework
+
+We improved our interrupt management implementation by introducing an Interrupt
+Manager framework, based on the currently on-going [rust-vmm vm-device](https://github.com/rust-vmm/vm-device)
+crates discussions. This move made the code significantly cleaner, and allowed
+us to remove several KVM related dependencies from crates like the PCI and
+virtio ones.
+
+### Development Tools
+
+In order to provide a better developer experience, we worked on improving our
+build, development and testing tools.
+Somehow similar to the excellent
+[Firecracker's devtool](https://github.com/firecracker-microvm/firecracker/blob/master/tools/devtool),
+we now provide a [dev_cli script](https://github.com/cloud-hypervisor/cloud-hypervisor/blob/master/scripts/dev_cli.sh).
+
+With this new tool, our users and contributors will be able to build and test
+Cloud Hypervisor through a containerized environment.
+
+### Kata Containers Integration
+
+We spent some significant time and efforts debugging and fixing our integration
+with the [Kata Containers](https://github.com/kata-containers) project. Cloud
+Hypervisor is now a fully supported Kata Containers hypervisor, and is
+integrated into the project's CI.
