This is a maintenance release. The following items were fixed and/or added:

VMM: Introduced general improvements in nested visualization area
GUI: Brought back Restore current snapshot checkbox of Close VM dialog (bugs #21189, #21491)
GUI: Fixes and validation for VM settings USB filters editor, filter port value is now properly saved/restored

Main/UefiVariableStore: Added API to add signatures to the MOK list (Machine Owner Key)
VBoxManage: Introduced modifynvram enrollmok sub-command to enroll Machine Owner Key into NVRAM, so Linux guest kernel can pick it up in order to verify signature of modules signed with this key
Guest Control/Main: Fixed deleting files via built-in toolbox
Linux host: Added possibility to bypass kernel modules signature verification once VBOX_BYPASS_MODULES_SIGNATURE_CHECK="1" is specified in /etc/vbox/vbox.cfg, useful in case if Linux distribution does not provide necessary tools to verify kernel module signature
Linux Guest Additions and host Installer: Improved detection if system is running systemd as the init process
Linux Guest Additions and host drivers: Introduce initial support for kernel 6.3
Linux Guest Additions: Added possibility to bypass kernel modules signature verification once VBOX_BYPASS_MODULES_SIGNATURE_CHECK="1" is specified in /etc/virtualbox-guest-additions.conf, useful in case if Linux distribution does not provide necessary tools to verify kernel module signature
Linux Guest Additions: Added experimental support for kernel modules and user services reloading in the end of installation process, thus guest system reboot after Guest Additions (7.0.8 and newer) upgrade is no longer required in general case
Linux Guest Additions: Fixed vboxvideo build issue with RHEL 8.7, 9.1 and 9.2 kernels (bugs #21446 and #21450)
