VirtualBox 5.2.16 (released July 17 2018)

This is a maintenance release. The following items were fixed and/or added:

  • OVF: case insensitive comparison of manifest attribute values, to improve compatibility (bug #17357)
  • Linux: build for openSUSE 15.0 (bug #17554)
  • Linux: various build fixes for distribution builds, thank you Gianfranco Costamagna

VirtualBox 5.2.14 (released July 02 2018)

This is a maintenance release. The following items were fixed and/or added:

  • User interface: fixed a segmentation fault when accessing the interface through VNC (bug #16348)

  • Apple hosts: make kernel driver load with Mac OS Mojave pre-release (bug #17805).
  • Linux guests: made vboxvideo driver build with kernel 4.17 (bug #17801) and with pre-3.14 and EL 7.1 kernels (bug #17771)
