Anyone here know if Sampletank/Free uses VST2 or 3?

I’ve been using Sampletank/Free (VST2) for a while (originally with my old SONAR software) - the bass pack and the horns work nicely especially in a dense production. Setting it up in Cubase 8 Pro was a bit of a chore - not Cubase’s issue - all related to IKMultimedia. Occasionally, the Sampletank splash screen whites out. I’ve got current video software updates - not sure how to resolve that particular issue. I hope this helps -
