  • GUI: Snapshot Pane rework allowing to manage snapshot attributes, like name and description; reworked snapshot details which looks more clear, corresponds to VM Details pane and reflects current VM state difference according to last snapshot taken

  • NAT network: do not skip some port forwarding setup when multiple VMs are active (Windows hosts only; bug #17041)
  • Serial: fixed extremely rare misbehavior on VM poweroff
  • EFI: better video mode handling, supporting custom video modes and easier configuration (bug #6783)
  • BIOS: properly report floppy logical sectors per track for unusual formats
  • BIOS: update ATA disk parameter table vectors only if there is actually a corresponding ATA disk attached
  • PXE: speed up booting by better handling pending packets when the link is not up yet
  • VBoxManage: handle CPUID sub-leaf overrides better
  • Windows Additions: fix several 3D related crashes
  • Solaris hosts: allow increasing MTU size for host-only adapter to 9706 bytes to support jumbo frames
  • Linux Additions: on systems using systemd, make sure that only the Guest Additions timesync service is active
  • many unlisted fixes and improvements
