Which Unity version is compatible with Orbbec Astra Pro

I have read some of the forums here regarding Unity + Orbbec Astra Pro. The website originally claimed that Unity 5.3.1 is the most compatible, however, there were some users who used other newer version of Unity such as Unity 5.6.1/ Unity 2018 and they are working fine.

Pls shed some light onto why they are able to work? And shd I proceed with the latest version of Unity instead of what’s the recommended?

Btw, Unity 5.3.1 doesn’t have a video player function which I definitely need for my project.
