Each issue is ultimately part of an epic.

- **Milestone**. Each issue is assigned a milestone. This is 0.1, 0.2, ..., or 'Nebulous Future'. The milestone indicates when we
think the issue should get addressed.

- **Priority**. Each issue has a priority which is represented by the column in the [Prioritization](https://github.com/orgs/istio/projects/6) project. Priority can be one of
