Wujood, I'm using Unity version 2019.1.0f2 and the SDK seems to work with no or minimal errors. The only issue can be the textures, if you use any of the new Unity HD Render Pipelines in the updated project (if you update an existing project from a 2018 version, you won't switch to the new render pipeline, so you won't have the problem). If you do try it with the new render pipeline it's an easy task to update the mesh shader types, and it's just a cosmetic issue anyway.
I've not tried it with any of the later versions yet.
If you update your project, I always recommend making a backup of the entire project beforehand, just in case. It's worth the bit of extra preparation to avoid possible frustration.
