# The following items were fixed and/or added:
* VMM: fixed a Guru Meditation VERR_ACCESS_DENIED with certain guests
* VMM: fixed a Guru Meditation VERR_PAGE_TABLE_NOT_PRESENT with Ubuntu 32-bit guests with nested paging enabled on AMD CPUs
* 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)
* 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
* Host-only Networking: lifted the maximal number of interfaces to 128 on Linux and Mac OS X hosts (there is no such limitation for Solaris and Windows hosts)
* EFI: fixed wrong SEC/PEI Core entry point calculation
* VRDP: fixed a display update problem
* Main: set the proper VM state if savestate failed for some reason
* Main: more useful error message if a medium is inaccessible

* Mac OS X hosts: addressed issues running on Mountain Lion Preview 3
* Linux hosts: Linux 3.4 compile fixes
* Linux hosts: fixed wrong help path in some rpm-based packages
* Guest Additions: fixed handling of custom environment variables during VBoxManage guestcontrol execute
* Windows Additions: fixed guest driver crash of VBoxSF in certain cases (4.1.10 regression)
* 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
