I've started experimenting with GitHub milestones in the DataFusion project. I find it helpful to have a prioritized list of issues that I am working on for the next release, and the milestone description can be used as a way of communicating our roadmap rather than maintaining a separate document somewhere else.
Here is the milestone for DataFusion 15.0.0, for example [1]. Would others find this helpful? The plan would be to release 15.0.0 on the target date even if there are unfinished issues in the milestone. Remaining issues would be rolled over to the next release, so this won't affect the release frequency. Andy. [1] https://github.com/apache/arrow-datafusion/milestone/5
