Do they follow semantic versioning? If so, does that mean there have been 15 releases with major breaking changes?

They switched from 0.14 to 15.0 to reflect react being production ready. See here: https://facebook.github.io/react/blog/2016/02/19/new-version...

Something interesting to note: usually code written for one version of React is compatible with the next version of React as long as no deprecated features are used. Usually React's breaking changes between major versions are restricted to breaking deprecated things and making new stuff deprecated.

I think it was open sourced as version 0.8 or something along those lines, so that would be 8 major releases.
