+contributors: [Cloud Hypervisor Team]
+---
+This release has been tracked in our [roadmap project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration
+v36.0. The following user visible changes have been made:
+
+### Command Line Changes
+
+We switched back to use the `clap` crate to create our command line,
+since the `argh` crate is barely maintained. There were several syntax
+changes:
+
+* All `--option value` commands now are `--option=value`.
+* The `--disk DISK1 --disk DISK2` command now is `--disk DISK1 DISK2`.
+* The `-v -v -v`command now is `-vvv`.
+
+Note: the released binary size increased around 0.3M due to this change.
+
+### Enabled Features Reported via API Endpoint and CLI
+
+Now the enabled (Cargo) features of the running Cloud Hypervisor
+instance can be queried via API endpoint (`/vmm.ping`) and CLI
+(`--version -v`).
+
+### NUMA Support for PCI segments
+
+The `--numa` command is augmented with a new option `pci_segment=`, so
+that users can define the relationship between PCI segments and NUMA
+nodes. Examples can be found from the [memory documentation](docs/memory.md)
+
+### CPU Topology Support on AMD Platforms
+
+Now the CPU topology on x86_64 platforms supports multiple vendors.
+
+### Unix Socket Backend for Serial Port
+
+The `--serial` command is augmented with a new option `socket=`, allowing
+users to access the serial port using a Unix socket.
+
+### AIO Backend for Block Devices
+
+An AIO backend is added for `virtio-block` devices to improve block
+device performance when the `io_uring` feature is not supported by the
+host Operating System.
+
+### Documentation Improvements
+
+* New [documentation](docs/coverage.md) for collecting coverage data
+* Various typo fixes
+
+### Notable Bug Fixes
+
+* Fix a deadlock when TDX is enabled (#5845)
+* Only advertise AMX feature bits to guest when the AMX cpu feature is
+  enabled (#5834)
+* Correct default value for vCPU topology on AArch64 (#5893)
