   We are not pinning our dependencies. Reasons are explained in http://airflow.apache.org/docs/apache-airflow/stable/installation.html#constraints-files
   
   Instead of pinning, you should use constraints to install Airflow; http://airflow.apache.org/docs/apache-airflow/stable/installation.html#installation-script . This is the only recommended way of installing Airflow that is guaranteed to work without manualle
   
   In https://raw.githubusercontent.com/apache/airflow/constraints-1.10.9/constraints-2.7.txt you can see:
   
   `Flask-SQLAlchemy==2.4.1`
   
   So all is good.
