--------------------------------------------

Sorry yes, I forgot that people could put custom sections and entries in the airflow.cfg.

>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-5410
>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: configuration
>    Affects Versions: 1.10.5
>            Reporter: Qian Yu
>            Priority: Major
>
> The following commit changed the behavior of configuration parsing globally (although the commit message only says "kubernetes"):
>  AIRFLOW-4316 Support setting kubernetes_environment_variables config section from env var (#5668)
>  
> This used to work:
> {code:python}
> [mysection]
> Guess = "test"{code}
> {code:python}
> assert conf.get("mysection", "Guess")  == "test"{code}
> It stopped working since 1.10.5. It'll break because the key "Guess" is not found. To get around the issue, "Guess" needs to be changed to all lower case
>  "guess". This change can cause surprises because it is not obvious from the changelog this commit changed conf parsing everywhere.
