+# v26.0
+
+This release has been tracked through the [v26.0
+project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/30).
+
+### SMBIOS Improvements via `--platform`
+
+`--platform` and the appropriate API structure has gained support for supplying
+OEM strings (primarily used to communicate metadata to systemd in the guest)
+(#4319, #4446) and support for specifying the UUID (#4389.)
+
+### Unified Binary MSHV and KVM Support
+
+Support for both the MSHV and KVM hypervisors can be compiled into the same
+binary with the detection of the hypervisor to use made at runtime.
+
+### Notable Bug Fixes
+
+* The prefetchable flag is preserved on BARs for VFIO devices (#4353, #4454)
+* PCI Express capabilties for functionality we do not support are now filtered
+  out (#4456)
+* GDB breakpoint support is more reliable (#4354, #4363)
+* `SIGINT` and `SIGTERM` signals are now handled before the VM has booted
+  (#4269, #4293)
+* Multiple API event loop handling bug fixes (#4309, #4362)
+* Incorrect assumptions in virtio queue numbering were addressed, allowing
+  the`virtio-fs` driver in OVMF to be used (#4341, #4314)
+* VHDX file format header fix (#4291)
+* The same VFIO device cannot be added twice (#4453, #4463)
+* SMBIOS tables were being incorrectly generated (#4442)
+
+### Deprecations
+
+Deprecated features will be removed in a subsequent release and users should
+plan to use alternatives.
+
+* The top-level `kernel` and `initramfs` members on the `VmConfig` have been
+  moved inside a `PayloadConfig` as the `payload` member. The OpenAPI document
+  has been updated to reflect the change and the old API members continue to
+  function and are mapped to the new version. The expectation is that these old
+  versions will be removed in the v28.0 release.
+
+### Removals
+
+The following functionality has been removed:
+
+* The unused `poll_queue` parameter has been removed from `--disk` and
+  equivalent. This was residual from the the removal of the `vhost-user-block`
+  spawning feature (#4402.)
+
