Thanks for the PR!

I'll import this and see what happens.

If you're blocked by this, yarn has some way to override the modules so you can force recursive dependencies to update beyond the allowed range.

@kassens I'm not really familiar with flow, could you help me troubleshoot the CI tests?

This turns out to be somewhat involved internally as we require not too many versions of third party libraries. Relay only uses immutable for the compiler and we'll somewhat soon replace that code so, I'm inclined to close this PR.

Good news for you is that shipped websites built with Relay don't need the immutable dependency for Relay.
