I'd like to start using the EMR hooks and operators (for example https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/hooks/emr_hook.py). However, they were added on June 30, and the latest release is 1.7.1.3 dated June 13. So a couple of questions:
1) What is the best practice if I want newer features? Is running off the latest master a terrible idea? How do other folks do this? 2) What's the release schedule? From the commit history it looks like a lot of stuff has been added in the last few months but isn't available in a release yet. Somewhat relatedly, I didn't see any documentation on upgrading. I presume there may be database migrations involved? How does one upgrade the db from version X to version Y, or know if migrations are needed? Thanks, Ben
