Important

When upgrading from Boost 1.x, you need to migrate the Babel plugin to the new Metro plugin. See the documentation.

  • ⚙️ Metro config plugin. Boost now provides a Metro config plugin instead of a Babel plugin, making a lot of the new features below possible.
  • 🚀 Five new optimizers. Optimize Animated and ActivityIndicator components, as well as StyleSheet, Platform and other code.
  • 🎨 Uniwind support. Resolving one of the longest-standing feature requests, Boost now supports Uniwind, preserving styling in optimized components.
  • 🧠 Less bail-outs. Boost now analyzes ancestors and helper functions across files.
  • 🖼️ Improved Image optimization. Static sources, callbacks, and accessibility props get better support.
  • 🛡️ Improved runtime behavior parity. A ton of fixes and improvements around edge cases ensuring better parity with pure React Native.
  • 📱 React Native 0.88 support. Runtime parity is validated against the latest React Native 0.88 RC.
  • 🧰 Clearer configuration. Optimizers, integrations, assumptions, and logging now use one developer-friendly API.
