             Summary: Clean up git branches (remove old + implement versions)
                 Key: AIRFLOW-135
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-135
             Project: Apache Airflow
          Issue Type: Improvement
            Reporter: Jeremiah Lowin
            Priority: Minor
             Fix For: Airflow 1.8


We have a large number of branches in the git repo, most of which are old features -- I would bet hardly any of them are active. I think they should be deleted if possible. In addition, we should begin using branches (as opposed to tags) to allow easy switching between Airflow versions. Spark (https://github.com/apache/spark) uses the format {{branch-X.X}}; others like Kafka (https://github.com/apache/kafka) simply use a version number. But this is an important way to browse the history and, most importantly, can't be overwritten like a tag (since tags point at commits and commits can be rebased away).
