### Apache Airflow version 2.1.4 (latest released) ### Operating System Amazon Linux 2 ### Versions of Apache Airflow Providers _No response_ ### Deployment Docker-Compose ### Deployment details _No response_ ### What happened Say, for example, you have a DAG that has a sensor. This DAG is set to run every minute, with max_active_runs=1, and catchup=False. This sensor may pass 1 or more times per day. Previously, when this sensor is satisfied once per day, there is 1 DAG run for that given day. When the sensor is satisfied twice per day, there are 2 DAG runs for that given day. With the new queued dag run state, new dag runs will be queued for each minute (up to AIRFLOW__CORE__MAX_QUEUED_RUNS_PER_DAG), this seems to be against the spirit of catchup=False. This means that if a dag run is waiting on a sensor for longer than the schedule_interval, it will still in effect 'catchup' due to the queued dag runs. ### What you expected to happen _No response_ ### How to reproduce _No response_ ### Anything else _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
