+# v27.0
+
+This release has been tracked in our new [roadmap
+project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration
+v27.0.
+
+### Community Engagement
+
+A new mailing list has been created to support broader community discussions.
+Please consider [subscribing](https://lists.cloudhypervisor.org/g/dev/); an
+announcement of a regular meeting will be announced via this list shortly.
+
+### Prebuilt Packages
+
+Prebuilt packages are now available. Please see [this
+document](https://github.com/cloud-hypervisor/obs-packaging/blob/main/README.md)
+on how to install. These packages also include packages for the different
+firmware options available.
+
+### Network Device MTU Exposed to Guest
+
+The MTU for the TAP device associated with a `virtio-net` device is now exposed
+to the guest. If the user provides a MTU with `--net mtu=..` then that MTU is
+applied to created TAP interfaces. This functionality is also exposed for
+`vhost-user-net` devices including those created with the reference backend
+(#4658, #4676.)
+
+### Boot Tracing
+
+Support for generating a trace report for the boot time has been added
+including a script for generating an SVG from that trace (#4659.)
+
+### Simplified Build Feature Flags
+
+The set of feature flags, for e.g. experimental features, have been simplified:
+
+* `msvh` and `kvm` features provide support for those specific hypervisors
+  (with `kvm` enabled by default),
+* `tdx` provides support for Intel TDX; and although there is no MSHV support
+  now it is now possible to compile with the `mshv` feature (#4696,)
+* `tracing` adds support for boot tracing,
+* `guest_debug` now covers both support for gdbing a guest (formerly `gdb`
+  feature) and dumping guest memory.
+
+The following feature flags were removed as the functionality was enabled by
+default: `amx`, `fwdebug`, `cmos` and `common` (#4679, #4632.)
+
+### Asynchronous Kernel Loading
+
+AArch64 has gained support for loading the guest kernel asynchronously like
+x86-64. (#4538)
+
+### GDB Support for AArch64
+
+GDB stub support (accessed through `--gdb` under `guest_debug` feature) is now
+available on AArch64 as well as as x86-64.
+
+### Notable Bug Fixes
+
+* This version incorporates a version of `virtio-queue` that addresses an issue
+  where a rogue guest can potentially DoS the VMM (rust-vmm/vm-virtio#196.)
+* Improvements around PTY handling for `virtio-console` and serial devices
+  (#4520, #4533, #4535.)
+* Improved error handling in virtio devices (#4626, #4605, #4509, #4631, #4697)
+
+### Deprecations
+
+Deprecated features will be removed in a subsequent release and users should
+plan to use alternatives.
+
+* Booting legacy firmware (compiled without a PVH header) has been deprecated.
+  All the firmware options (Cloud Hypervisor OVMF and Rust Hypervisor Firmware)
+  support booting with PVH so support for loading firmware in a legacy mode is no
+  longer needed. This functionality will be removed in the next release.
