Hi, I'm a new user for airflow, and I'm wondering when the next release of airflow is. My company uses mssql servers for its backend. I very quickly ran into a bug that was fixed in May <https://github.com/apache/incubator-airflow/commit/e7e655fde3c29742149d047028cbb21aecba86ed>. I've since patched that file in my installation, but I can't help but wonder what other critical issues have been fixed since version 1.7.1.3.
I've considered updating my installation to some commit on the master branch, but I'm hesitant to pick a non-stable version. Even so, how would I update airflow from source? Copy the contents of https://github.com/apache/incubator-airflow to /usr/lib/python2.7/site-packages after installing 1.7.1.3 through pip? Thanks, Paul Zaczkiewicz
