  • GUI: Introduced generic changes in settings dialogs
  • VirtioNet: Fixed broken network after loading saved state (bug #21172)
  • Storage: Added support for increasing the size of the following VMDK image variants: monolithicFlat, monolithicSparse, twoGbMaxExtentSparse, twoGbMaxExtentFlat
  • VBoxManage: Added missing --directory switch for guestcontrol mktemp command
