Special thanks to our EAP Champions 🥇👏

As part of our effort to maximize the release quality of Kotlin 1.7.20, we launched an experimental program where we invited people working on production-grade Kotlin projects to migrate them to the new version. While validating their projects on 1.7.20-Beta and 1.7.20-RC, they reported issues and helped us stabilize the release. For example, they discovered a major issue with the new Kotlin/Native memory model and several issues with the compatibility of Kotlin compiler plugins. These people are our EAP Champions and we want to give a big thank you to them:
