o-nikolas opened a new pull request #16469: URL: https://github.com/apache/airflow/pull/16469
Currently a pre 1.0 version of Watchtower is being used. There have been many bug fixes and improvements since this version (the changelog can be found [here](https://github.com/kislyuk/watchtower/blob/develop/Changes.rst)). This change updates Airflow's specified version in setup.py. I have ran the following commands to test this locally: `./breeze generate-constraints --generate-constraints-mode source-providers` `./scripts/ci/testing/ci_run_airflow_testing.sh` I believe this is the only line that needs to be changed for a dependency upgrade ([see discussion I started on the community slack](https://apache-airflow.slack.com/archives/CCPRP7943/p1621024646304600)) but please correct me if I'm wrong here. <!-- Thank you for contributing!
