Please don't re-open closed bugs that are included in releases, since
that messes up Jira's change log for the release. Bugs normally
transition from Open to Resolved/Fixed, then to Closed when a release is
made. It's okay to re-open a bug whose fix has not yet been released,
but it is generally better to create a new bug in this case too.
Ideally I could modify the Jira permissions so that non-administrators
cannot transition bugs from Closed to Open and are forced to instead
start a new bug, but that does not appear to be possible.
