- VMM: preserve segment limits and attributes when switching to unreal mode required for some legacy guests to work properly (VT-x without unrestricted guest execution only; bug #9941)
- VMM: fixed a VM hang after a resume from pause / savestate with SMP guests in rare cases
- 3D Support: several fixes for the Windows WDDM video driver crash
- NAT: fixed a crash on attempt to process ICMP datagram under some circumstances (bug #10527)
- EFI: fixed wrong SEC/PEI Core entry point calculation (bug #10531)
- VRDP: fixed a display update problem (bug #10503)
- Main: set the proper VM state if savestate failed for some reason (bug #6189)

- Windows Additions: don't load the WDDM driver if 3D support is not available for Windows 8 guests to keep the guest maintainable in that case (still better to miss some features than providing a blank screen)
- Solaris Additions: added support for X.org Server 1.11 and 1.12
