VirtualBox v6.1.2 Changelog:
Virtualization core: fixed performance issue observed with Windows XP guests on AMD hosts (6.0.0 regression; bug #19152)
Virtualization core: consistent IBRS/IBPB CPUID feature reporting, avoids crash of NetBSD 9.0 RC1 installer (bug #19146)
GUI: fixed updating of runtime info
GUI: in Display settings, do not show "2D video acceleration" checkbox if it is meaningless for the selected graphics adapter
Audio: fixed audio input handling when VRDE is enabled
Audio: fixed crash in the HDA emulation when using multi-speaker configurations
Storage: fixed use of encrypted disks with snapshots involved (6.1.0 regression; bug #19160)
Storage: improve performance of virtio-scsi
Storage: read-only support for compressed clusters in QCOW2 images
Windows installer: include unintentionally dropped vbox-img.exe utility again
Windows host: when installing or removing an extension pack, retry the sometimes failing directory renaming (usually caused by anti-virus software accessing the directory)
Linux host: Support Linux 5.5 (guest additions not yet)
Windows guest: accelerate 2D video decoding (scaling and color space conversion) if the VM is configured to use VBoxSVGA with 3D enabled
Windows guest: fix guest additions installer to upgrade the mouse filter driver reliably
Windows guest: when uninstalling older Guest Additions with old 3D support enabled try restoring original Direct3D files
Linux guest: improve resize and multi-monitor handling for VMs using VMSVGA (known remaining issue: do not disable a monitor "in the middle", causes confusion)
