Retrospective Topics

• We should update manual testing script to automatically build hermes versions of RNTestProject. Added support for RNTester in facebook/react-native@732ac17
• We should audit the testing instructions, it mentions checking Chrome Debugger...which isn't a use-case anymore for RNTester and RNTestProject and we probably want Flipper instructions
• @lunaleaps had bad experience with not being able to exit debugging experience on Android
  • We picked facebook/react-native@49b3b31 to help
• @tido64 found issues on iOS with Image warning for unhandled promise?
• Maybe we should add Release configuration tests to manual test script
• We need a way to get sense of scale of people testing RC
• Questions about Hermes debugging and new app screen, instructions on the new app screen don't make sense for new apps using Hermes?
• Can we update react-native cli to allow option to create Hermes template app -- it'll make testing a little easier
• Apple Silicon (M1) machines were still not widely available to help speed up testing needs (not many have one, Circle CI didn't have one either)

Just a quick 🤞 that the necessary iOS codegen / FBReactNativeSpec etc files are committed on the branch - I think they are still necessary after branch cut. Cheers

We will news to cherry pick facebook/react-native#32074 once merged to fix the ability for apps to run jest tests.

RC is already out !!! https://npmjs.com/package/react-native/v/0.66.0-rc.0

[fkgozali]

[Pick Request] facebook/react-native@49b3b31

This is to address error logbox when connecting to Chrome debugger.

[heroic]

Any specific reason for this to be 66 and not 65.2?

[NickGerleman]

@heroic 0.66 is coming soon after 0.65, but the jump from 0.65 to 0.66 has four months of commits! Some of these are breaking changes that we are working on documenting, like the removal of some deprecated components like Picker.
