In addition, the following items were fixed and/or added: In addition, the following items were fixed and/or added: Virtualization core: Improvements for nested hardware-virtualization on Intel CPUs, Windows works now on outer VM (needs beta VirtualBox) Virtualization core: Drop recompiler, i.e. running VMs now needs a CPU supporting hardware virtualization Runtime: Works now on hosts with many CPUs (limit now 1024) GUI: Storage and Network settings pages bug-fixes and usability optimization GUI: Show VM CPU load as part of status bar CPU indicator GUI: Media enumeration fixes GUI: Popup messages mouse click fix GUI: Details pane fixes GUI: Added multimedia keys to soft keyboard and other improvements GUI: Fix and unify geometry save/restore in various dialogs Cloud: More flexibility in VM export and import to Oracle Cloud Infrastructure, add free-form tags to cloud images Graphics: Remove 3D support for VBoxVGA (old one deprecated with 6.0) Graphics: Additional texture format supportd on Windows host Graphics: Improved fix for flickering on Windows host NAT: Fix TFTP OACK response, send only if request has options API: Reduce the amount of leftovers from Move VM function Audio: Allow changing the host audio backend while the VM is in saved state vboximg-mount: Now also available on Linux host VBoxManage: More cloud functionality coverage, e.g. starting a cloud instance VBoxManage: As part of the guest control feature support moving multiple source files/directories to a target directory macOS host: Fix VM crashes (most visible on macOS Catalina) Windows host: Improve USB device capturing accuracy EFI: Switch to newer firmware code base and add NVRAM support, should improve compatibility with OSes significantly This is a major update. The following major new features were added: Implemented support for importing a virtual machine from Oracle Cloud Infrastructure Extended support for exporting a virtual machine to Oracle Cloud Infrastructure, allowing the creation of multiple virtual machines without re-uploading. Also added option to export a VM to the cloud using the more efficient variant "paravirtialized" Virtualization core: Support for nested hardware-virtualization on Intel CPUs (starting with 5th generation Core i, codename Broadwell) Graphics: New style 3D support (with VBoxSVGA and VMSVGA) remains, old style 3D support (with VBoxVGA) has been completely removed Shared Clipboard: Implemented experimental support for file transfers (Windows hosts/guests only at the moment). Needs to be enabled via VBoxManage (disabled by default). In addition, the following items were fixed and/or added: GUI: Improved the VISO creation and file manager dialogs GUI: Virtual machine list of VirtualBox Manager was improved. Machine groups are now more obvious visually and VM search functionality has been improved. Global Tools element can now be pinned in place, to avoid scrolling it with rest of machine list GUI: Virtual machine details pane is now extended with embedded editors for certain VM attributes which we decided as the most important, allowing user to edit them on-the-fly by clicking corresponding hyper-links without opening VM settings dialog GUI: Internal medium enumeration routines were optimized to reduce the load and optimize the performance in cases when user have lots of media registered. Also, we again allowed to add existing media (and create new) via Virtual Media Manager GUI: VM storage settings page was adjusted a bit in usability regard. User is now allowed to change controller bus type and can move attachments between the controllers by using drag and drop GUI: Added a new soft (virtual) keyboard enabling keyboard inputs to guests GUI: Improved and extended the Session Information dialog Input: Added support for horizontal scrolling in the PS/2 mouse device using the IntelliMouse Explorer protocol. Note that this support is automatically used by Linux guests but not by Windows guests vboximg-mount: Experimental support for direct read-only access to NTFS, FAT and ext2/3/4 filesystems inside a disk image without the need for support on the host Guest Control/VBoxManage: Added support for specifying multiple sources when renaming guest files
