Subject Re: Longer term Airflow planning
Date Wed, 10 Apr 2019 14:47:51 GMT
The Jira is a mess and it require committers time to organize it.
Ideally users should report issues and committers should tag them with priority, milestone
/ fix version, labels  (This is how for example it's done with https://github.com/pandas-dev/pandas
)

When I have time I try to stack list of Jira issues that require committers attention and
ashb fix them but it's progressing slowly.

I think that at least it would be great if the version field in the Jira will be mandatory
when user submit ticket.

At the end... committers simply don't have time for this. They don't have enough time for
reviewing PRs as well so I doubt something will change in the near future.
