The latest Vuforia release contains several highly requested features along with performance improvements. You can now track an unrestricted number of Image Targets simultaneously, enabling even more sophisticated and exciting experiences. We’ve also improved the efficiency of our SDK initialization process and memory management on iOS and Android and provided faster detection times for VuMarks. Additionally we’ve fixed an issue affecting Nexus devices that resulted in a dark screen after some OS updates.
