 - Initiated discussions with partners to support a [Copilot rotation](/contributing/release-roles-responsibilities#release-role-2--release-copilot). We hope this effort will improve transparency of the process and inform our partners where to invest to support React Native releases and eco-system.
 - [Onboarded several Release Supporters and Testers from the community](https://github.com/reactwg/react-native-releases/discussions/11). We had put a call-out for help last half and so many folks stepped up! The feedback from our testers and supporters have **helped us fix crucial bugs** and regressions, especially around the new architecture, for the upcoming release. Thank you to everyone who signed up and tested out the release!
 
-With React Native 0.69 we will continue refining this process, ideally getting partners to provide earlier release signal and onboarding co-pilots. As always, [any feedback is more than welcome](https://github.com/reactwg/react-native-releases/discussions).
