Coming one month after the VirtualBox 5.1.28 release, which probably most of you out there use right now on your personal computers, VirtualBox 5.1.30 contains a fix for a Glibc 2.26 compilation bug for Linux hosts and a 3D-related crash for Windows guest that use the Windows Additions package. For Mac OS X hosts, the update fixes a “double mouse cursor” issue that occurred when using the mouse integration feature without installing the Guest Additions. The issue was, in fact, a bug present in the Qt 5.6 framework, which is now patched in Qt 5.6.3 and later versions.
