  Description accepts html formatting characters.

  Open Statuses:
    Unconfirmed   = New, has not been verified or reproduced
    Untriaged     = Confirmed, not reviewed for priority and assignment
    Available     = Triaged, but no owner assigned
    Assigned      = In someone's queue, but not started
    Started       = Work in progress
    Upstream      = Issue has been reported to another project

  Closed Statuses:
    Fixed         = Work completed, needs verification
    Verified      = Test or reporter verified that the fix works
    Duplicate     = Same root cause as another issue
    WontFix       = Cannot reproduce, works as intended, or obsolete
    FixUnreleased = Security bug fixed on all branches, not released
    Invalid       = Not a valid issue report

  Types:
    Bug     = Software not working correctly
    Feature = Request for new or improved feature
    Task    = Project or work that doesn't change code
    Cleanup = Code maintenance unrelated to bugs

  Priority:
    0 = Critical. Resolve now. Blocks other work or users need immediate update.
    1 = High. Required for the specified milestone release.
    2 = Normal. Desired for, but does not block, the specified milestone release.
    3 = Low. Nice to have, but not important enough to start work on yet.
