+# v0.7.0
+
+This release has been tracked through the [0.7.0 project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/7).
+
+Highlights for `cloud-hypervisor` version 0.7.0 include:
+
+### Block, Network, Persistent Memory (PMEM), VirtioFS and Vsock hotplug
+
+Further to our effort to support modifying a running guest we now support
+hotplug and unplug of the following virtio backed devices: block, network,
+pmem, virtio-fs and vsock. This functionality is available on the (default) PCI
+based tranport and is exposed through the HTTP API. The `ch-remote` utility
+provides a CLI for adding or removing these device types after the VM has
+booted. User can use the `id` parameter on the devices to choose names for
+devices to ease their removal.
+
+### Alternative `libc` Support
+
+Cloud Hypervisor can now be compiled with the `musl` C library and this release
+contains a static binary compiled using that toolchain.
+
+### Multithreaded Multi Queued `vhost-user` Backends
+
+The `vhost-user` backends for network and block support that are shipped by
+Cloud Hypervisor have been enhanced to support multiple threads and queues to
+improve throughput. These backends are used automatically if `vhost_user=true`
+is passed when the devices are created.
+
+### Initial RamFS Support
+
+By passing the `--initramfs` command line option the user can specify a file to
+be loaded into the guest memory to be used as the kernel initial filesystem.
+This is usually used to allow the loading of drivers needed to be able to
+access the real root filesystem but it can also be used standalone for a very
+minimal image.
+
+### Alternative Memory Hotplug: `virtio-mem`
+
+As well as supporting ACPI based hotplug Cloud Hypervisor now supports using
+the `virtio-mem` hotplug alternative. This can be controlled by the
+`hotplug_method` parameter on the `--memory` command line option. It currently
+requires kernel patches to be able to support it.
+
+### `Seccomp` Sandboxing
+
+Cloud Hypervisor now has support for restricting the system calls that the
+process can use via the `seccomp` security API. This on by default and is
+controlled by the `--seccomp` command line option.
+
+### Updated Distribution Support
+
+With the release of Ubuntu 20.04 we have added that to the list of supported
+distributions and is part of our regular testing programme.
+
+### Command Line and API Changes
+
+This is non exhaustive list of HTTP API and command line changes
+
+* New `id` fields added for devices to allow them to be named to ease removal.
+  If no name is specified the VMM chooses one.
+* Use `--memory`'s `shared` and `hugepages` controls for determining backing
+  memory instead of providing a path.
+* The `--vsock` parameter only takes one device as the Linux kernel only
+  supports a single Vsock device. The REST API has removed the vector for this
+  option and replaced it with a single optional field.
+* There is enhanced validation of the command line and API provided
+  configurations to ensure that the provided options are compatible e.g. that
+  shared memory is in use if any attempt is made to used a `vhost-user` backed
+  device.
+* `ch-remote` has added `add-disk`, `add-fs`, `add-net`, `add-pmem` and
+  `add-vsock` subcommands. For removal `remove-device` is used. The REST API
+  has appropriate new HTTP endpoints too.
+* Specifying a `size` with `--pmem` is no longer required and instead the size
+  will be obtained from the file. A `discard_writes` option has also been added
+  to provide the equivalent of a read-only file.
+* The parameters to `--block-backend` have been changed to more closely align
+  with those used by `--disk`.
+
