A beta version of SDK 8 is now available for developers on the download page. Unity developers will be pleased to know that SDK 8 added AR-view functionality to the Unity editor. Being able to test and tweak your augmented reality project, hassle-free, during app creation greatly reduces development and prototyping time.
Additionally, developers can use the Unity Remote feature to test Instant Tracking using a remote camera (e.g. a smartphone or tablet).
