Breaking Release Checklist

• Ensure that the forc migrate tool in the latest patch release before the breaking change release contains all migration steps.
• Promote experimental features to standard features:
  • Remove feature flags and all conditional code from the compiler.
  • Remove experimental cfg attributes from all the Sway codebase in the sway repository. (E.g., std library, E2E tests, in-language tests, etc.)
  • Remove testing experimental features from E2E tests by deleting all the test.<feature>.toml files.
  • Remove testing experimental features from ci.yml.
  • Close the GitHub tracking issues.
• In the breaking change release, unregister all the migration steps in the forc migrate. (Do not delete the migrations. We want to keep them as examples for similar future migrations and for learning purposes.)
• Update documentation;
  • Ensure that the experimental feature itself is fully documented.
  • Ensure that all Notes describing the feature as experimental are removed.
  • Ensure that all related documentation is updated.
