+# v34.0
+
+This release has been tracked in our [roadmap
+project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration
+v34.0. The following user visible changes have been made:
+
+### Paravirtualised Panic Device Support
+
+A new device has been added that can communicate when the guest kernel has
+panicked and share those details with the VMM. This is controlled with a new
+`--pvpanic` command line option and JSON API change equivalent. (#5526)
+
+### Improvements to VM Core Dump
+
+Requesting to dump the guest memory as core dump will now transparently pause
+the VM if required; returning to the original state after. (#5604)
+
+### QCOW2 Support for Backing Files
+
+The support for QCOW2 files has been enhanced to include support for using
+backing files. (#5573)
+
+### Minimum Host Kernel Bump
+
+The minimum supported host kernel is now 5.13 in order to incorporate a bug fix
+for `KVM_FEATURE_ASYNC_PF_INT` functionality. (#5626)
+
+### Notable Bug Fixes
+
+* The x86 emulator is only compiled in if MSHV is compiled in (the kernel
+  carries out this job with KVM) (#5561).
+* A regression has been fixed in VFIO support for devices that use MSI rather
+  than MSI-X (#5658).
+* When triggering a VM shutdown or reset via I/O the vCPU thread will be
+  blocked until that asynchronous event has been received (#5645).
+* Pausing a VM is now a synchronous action with the request only completing
+  when all vCPUs are paused (#5611).
+* Event monitor support now correctly supports concurrent access (#5633).
+* Bug fixes for the QCOW2 file support (#5573).
