New in Oracle VM VirtualBox SDK 7.0.0 Build 153978 (Oct 11, 2022)

This is a major update. The following major new features were added:
Virtual machines can be fully encrypted now, including the VM config logs and saved states (CLI only for now)
OCI: Cloud virtual machines can be added to Virtual Machine Manager and controlled as local VMs
OCI: Cloud networks can now be configured via Network Manager tool same way as it is done for Host-only and NAT networks
GUI: Added a new utility similar to "top" or "resource monitor" which lists peformance statistics (CPU usage, RAM usage, disk I/O rate, etc.) of running guests
GUI: Reworked the new vm wizard to integrate the unattended guest OS installation and to have a more streamlined work flow
GUI: Added a new help viewer widget which enables the user manual to be navigated and searched
GUI: Adding new notification center unifying most of running progresses and error reporting around the GUI
GUI: Improved theme support on all platforms. Linux and macOS use native engine while for Windows host it is separately implemented.
GUI: Large icon update.
Audio recording: Now using Vorbis as the default audio format for WebM containers. Opus is no longer being used.
Audio: Added "default" host driver type to make it possible to move VMs (appliances) between different platforms without the need of changing the audio driver explicitly. When the "default" driver is selected, the best audio backend option for a platform will be used. This is the default for newly created VMs.

VBoxSDL frontend: Fixed running on Windows hosts
macOS host: Fix VM crashes (most visible on macOS Catalina)
Linux host: Improve vboxweb systemd service dependency information
Linux host: Drop PCI passthrough, the current code is too incomplete (cannot handle PCIe devices at all), i.e. not useful enough
