In addition, the following items were fixed or added:

- Arm VMs: Note that the saved state of Arm VMs from VirtualBox 7.1 is incompatible with VirtualBox 7.2, so please shut down such VMs in saved state before upgrading to 7.2 (snapshots with associated saved state created with 7.1 will no longer work with 7.2)

- VMM: Improved x86_64 and Arm CPU feature reporting when using Windows Hyper-V as the virtualization engine
