In PDE, we are tagging our bugs in such a way that you can query our noteworthy items for each release. (starting with 3.4, ie., 3.4M1). We also plan on using this as a way on tagging what we are working on that we think will be noteworthy in a future release. This provides us a small way of doing our planning in a more transparent manner. I hope other teams will follow suit if they think it’s useful for their project.
