+        Batfish will become an AWS-managed open source project. It will remain available under the same open source
+license, and we will continue our work on the project in collaboration with the community. You are encouraged
+to continue asking questions via Slack, opening issues and PRs on GitHub, and participating in the community to
+improve Batfish for everyone.
