Re: mailing the dev list. Sure. Will do.
By the way, I'm not sure that this is an "incorrect" usage of JIRA. I
think it's a matter of consensus and consistency. I'm still getting
the hang of this consensus building concept for lazy consensus... I
should have used the dev list instead of just talking to a few people.
For the record, I Keith Turner did point out that there is a valid
case where you would put an unreleased version in the "affected
version". That would be when you know it is a bug that won't be fixed
by the time that version is released, so it will become an issue
against an existing release at some point in the future.
I'm ambivalent on the "right way" to use JIRA, though like to be
consistent, and to offer my help to clean up inconsistencies.
