-  Description
+Nested Virtualization Technology Performance Tuning
+  The performance of nested virtualization, a feature first introduced as a
+  preview in the v2.5 release, was improved. CPU and I/O performance of level 2
+  virtual machines (for example, a VM running on a KVM/QEMU VM that itself is a
+  VM on ACRN hypervisor) is now on par with a VM running on KVM on bare metal.
+  Read more in the :ref:`nested_virt` tutorial.
+
+Support loading OSes in ELF format
+  ACRN hypervisor now can load OS images packed in ELF (Executable and Linkable
+  Format). This adds flexibility to OSs such as Zephyr running in pre-launched
+  VMs.
