  # Reset issue events cache
  #
  # Since we do cache @event we need to reset cache in special cases:
  # * when an issue is updated
  # Events cache stored like  events/23-20130109142513.
  # The cache key includes updated_at timestamp.
  # Thus it will automatically generate a new fragment
  # when the event is updated because the key changes.
