[#1081](https://github.com/convox/rack/pull/1081) switches over to the native AWS::ECS::Service CloudFormation handler which gives a few improvements:

- Better swaps during changes that require ECS service replacement
- CloudFormation updates are contingent on the new deployment reaching steady state

This means when you deploy new code apps will now stay in `updating` state until the new release actually stabilizes and will roll back if it does not.
