caching, jobs, docker via sail, authentication and authorization, one command to have a full multi team/tenant SaaS app template via jet stream.
even rails doesn't have this, as you need to choose your own implementation for auth and access control, something like sidekick for job queue etc....

I'm excited for the new features and with octane you can get more reqs per second than Phoenix framework which should make it easier to scale apps with less resources.
