v0.78.0

• [Breaking] Update default server port to 8081. (891fe96 by @huntie)
• [Breaking] Remove metro-react-native-babel-transformer and metro-react-native-babel-preset, which will be published as @react-native/metro-babel-transformer and @react-native/babel-preset going forward. (799aa0a by @dmytrorykun)
• [Breaking] Remove runInspectorProxy option from server. (2b0b15d by @huntie)
  • This is a significant breaking change — Metro will no longer start a built-in Inspector Proxy.
  • To migrate today, integrators should create an InspectorProxy instance externally, and provide the relevant handlers to Metro.runServer(). For reference:
    • inspectorProxy.processRequest to ServerOptions.unstable_extraMiddleware.
    • inspectorProxy.createWebSocketListeners to ServerOptions.websocketEndpoints.
  • Recommended: In the very near future, we will be encapsulating this functionality in the @react-native/dev-middleware package, which will provide a batteries-included integration point for the above.
  • Please reach out to @huntie if you need support with this feature.
