One thing that we do that we think is pretty cool is that we figured out a way to include multiple versions of our SDK (and React Native) in a single binary, so stuff you build with old versions will continue to work.

Here are the docs for SDK 10 (based on RN 0.33.0): https://docs.getexponent.com/versions/v10.0.0/index.html

And here are the docs for SDK 9 (based on RN 0.31.0): https://docs.getexponent.com/versions/v9.0.0/index.html

You can use either one.

Also, all our stuff is open source, so just go back and find the old release tags on Github if you want older versions.
