+# v28.0
+
+This release has been tracked in our new [roadmap
+project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration
+v28.0.
+
+### Community Engagement (Reminder)
+
+Just a reminder that we have a new mailing list to support broader community
+discussions.  Please consider
+[subscribing](https://lists.cloudhypervisor.org/g/dev/). We plan to use
+this to announce a regular meeting for those interested in talking about Cloud
+Hypervisor development.
+
+### Long Term Support (LTS) Release
+
+This is the first version of Cloud Hypervisor to be released under the LTS
+release process. Point releases for bug fixes will be made for the next 18
+months; live migration and live upgrade will be supported between the point
+releases of the LTS.
+
+### Virtualised TPM Support
+
+Support for adding an emulated CRB TPM has been added. This has it's own [TPM
+documentation](docs/tpm.md).
+
+### Transparent Huge Page Support
+
+By default, but controllable through `--memory thp=off` if it possible to back
+the guest memory with Transparent Huge Pages (no file backing/`shared=off`)
+then this will be used resulting in improved boot performance.
+
+### README Quick Start Improved
+
+The README has been refreshed with the quick start guide updated to reflect the
+different firmware options and to recommend the use of pre-built binaries.
+
+### Notable Bug Fixes
+
+* Inappropriate Copy-on-Write of pinned pages (e.g. VFIO) leading to higher
+  memory consumption (#4835)
+* Multiple `virtio` device bug fixes found through fuzzing (#4859, #4799)
+* Large QCOW files (> 4TiB) are now supported (#4767)
+* Support for > 31 vCPUS on aarch64 (#4863)
+* Multiple fixes to OpenAPI specification file (#4720, #4811)
+* Programming of the MSI-X table has been optimised leading to faster boot on
+  newer Linux kernels (#4744)
+* Error on reboot from race to close TAP devices (#4871)
+* Non-spec compliant virtio-block read-only support (#4888)
+
+### Removals
+
+The following functionality has been removed:
+
+* Support for non-PVH firmware booting has been removed (#4511)
+* I/O ports used for older versions of firmware have been removed (#3926)
+* Deprecated API options for kernel/cmdline/initramfs have been removed (#4737)
