 # History

+- Revamped documentation website
+- [Deployment Tasks](http://dokku.viewdocs.io/dokku/deployment/deployment-tasks/)
+- Heroku-style management of [dockerfile processes](http://dokku.viewdocs.io/dokku/deployment/dockerfiles/#procfiles-and-multiple-processes)
+- Official [persistent storage plugin](http://dokku.viewdocs.io/dokku/dokku-storage/)
