I'm the only one working on this. Meanwhile, ZC is being worked on by six people. So it stands to reason that ZC 2.5 will be released well before this quest is done.

(That I have managed to be the most consistently productive developer while simultaneously developing this quest may or may not just be an incidental detail. In fact, I might suggest that there is causation here - having a quest of my own is a highly effective motivation for me to continue supporting ZC day in and day out, and there is a not inconsiderable mound of bugs which I have found only through developing this quest.)
