##### Note

`v2.0.0` syntax is now considered stable 🍾 (multiple production applications have switched from `v1.5.*` to `v2.*.*` following [the migration guide](docs.react-redux-firebase.com/history/v2.0.0/docs/v2-migration-guide.html), and test coverage is better than for `v1.5.*`). Merge conflicts with `master` have also been resolved. All of this means this release will be the final RC released on `next` before moving [`v2.0.0`](https://github.com/prescottprue/react-redux-firebase/tree/v2.0.0) to the `latest` tag on npm (the `latest` tag release will include merging to `master`).
