facebook/metro v0.78.1 on GitHub

[Feature]: Return promise from metro-cache's Cache.set to allow handling underlying async store errors (2845160 by @robhogan)
[Feature] Add base URL string overload to InspectorProxy.createWebSocketListeners (8522db1 by @huntie)

Note
v0.78.1 will be the final release of metro-inspector-proxy, which is being relocated into the React Native repo. In Metro v0.78.0, we removed builtin Inspector Proxy creation as a breaking change.

For React Native integrators: The @react-native/dev-middleware package will provide a batteries-included integration point replacing metro-inspector-proxy. We're working closely with Expo on the API for this which should be ready within the next two weeks — usage will be documented in the package README.
