How can we find the documentation of 1.5?

I found the official site have only 1.7. How to find the 1.5 one?

Currently this requires building the docs yourself for the version you desire. I believe versioned docs on the website are in the pipeline.

In general we have publishing the API and guides at a versioned URL on our roadmap, but that doesn’t help you today…
