I discovered the need to release 0.1.1, when I was informed that in WoW1.9 a tooltip can only contain up to 40 lines of text. Also, I discovered that prior to BossPanel 0.9.1, this would cause an error whenever someone moused-over the tooltip.
So I added a "display quest objectives for current area only" option, and threw in a few levels of falling back to try to stop the number of lines going over 40. It seems to work so far.
My fault for not checking it out on a character with more quests, really.
