+# v24.0
+
+This release has been tracked through the [v24.0
+project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/28).
+
+### Bypass Mode for `virtio-iommu`
+
+`virtio-iommu` specification describes how a device can be attached by default
+to a bypass domain. This feature is particularly helpful for booting a VM with
+guest software which doesn't support `virtio-iommu` but still need to access
+the device. Now that Cloud Hypervisor supports this feature, it can boot a VM
+with Rust Hypervisor Firmware or OVMF even if the `virtio-block` device exposing
+the disk image is placed behind a virtual IOMMU.
+
+### Ensure Identifiers Uniqueness
+
+Multiple checks have been added to the code to prevent devices with identical
+identifiers from being created, and therefore avoid unexpected behaviors at boot
+or whenever a device was hot plugged into the VM.
+
+### Sparse Mmap support
+
+Sparse mmap support has been added to both VFIO and vfio-user devices. This
+allows the device regions that are not fully mappable to be partially mapped.
+And the more a device region can be mapped into the guest address space, the
+fewer VM exits will be generated when this device is accessed. This directly
+impacts the performance related to this device.
+
+### Expose Platform Serial Number
+
+A new `serial_number` option has been added to `--platform`, allowing a user to
+set a specific serial number for the platform. This number is exposed to the
+guest through the SMBIOS.
+
+### Notable Bug Fixes
+
+* Fix loading RAW firmware (#4072)
+* Reject compressed QCOW images (#4055)
+* Reject virtio-mem resize if device is not activated (#4003)
+* Fix potential mmap leaks from VFIO/vfio-user MMIO regions (#4069)
+* Fix algorithm finding HOB memory resources (#3983)
+
+### Notable Improvements
+
+* Refactor interrupt handling (#4083)
+* Load kernel asynchronously (#4022)
+* Only create ACPI memory manager DSDT when resizable (#4013)
+
+### Deprecations
+
+Deprecated features will be removed in a subsequent release and users should
+plan to use alternatives
+
+* The `mergeable` option from the `virtio-pmem` support has been deprecated
+  (#3968)
+* The `dax` option from the `virtio-fs` support has been deprecated (#3889)
+
+### New on the Website
+
+A new blog post [Achieving Bare Metal Performance Within a Virtual
+Machine](https://www.cloudhypervisor.org/blog/achieving-bare-metal-performance-within-a-virtual-machine)
+has been added to the Cloud Hypervisor website.

+# v23.1
+
+This is a bug fix release. The following issues have been addressed:
+
+* Add some missing seccomp rules
+* Remove `virtio-fs` filesystem entries from config on removal
+* Do not delete API socket on API server start (#4026)
+* Reject `virtio-mem` resize if the guest doesn't activate the device
+* Fix OpenAPI naming of I/O throttling knobs
