v3.0.0

Upgrade Guide: https://github.com/formatjs/react-intl/blob/master/docs/Upgrade-Guide.md

TL;DR:

• Official TypeScript support
• New (& better) parser & formatters
• More performance: faster runtime & better preloading (SSR/Electron) support
• More spec-compliant (ICU & Intl API)
• Hooks & React 16 support.
• Smaller size

Thank you everyone who has helped out for this long process of rewriting React Intl almost from the ground up! The tremendous amount of feedback, great discussions, and early adopters and testers have made this an amazing process and great release, we couldn't have done it without you!

We hope this library can help you build great web apps that are accessible to more people in the world through globalization.
