Hi,When I try to upgrade airflow from 1.6.0 to 1.7.0, there seems to be some airflow database/metadata compatibility, e.g. some new column is added/removed to one airflow metadata table (sorry, I don't have the exact error for now).
Is this a known issue? I had to run 'airflow resetdb' to work it around, I am wondering if there is a upgrade script I can run, instead of wiping out all the historical metadata info.
