**Features:**

- [#59](https://github.com/FormidableLabs/react-fast-compare/pull/59). Rename exported to `isEqual` for TypeScript users.

**Breaking changes:**

**Infrastructure:**

- Upgrade lots of `devDependenices`
- Use `fast-deep-equal` tests directly in our correctness tests.
- Update CI to modern Node.js versions.
- Update Appveyor to use straight IE11 (not emulated IE9) because mocha no longer runs in IE9.
