Good to know. The advantage to using "trixie" as opposed to "testing" is, it seems to me, to be that when Trixie finally goes GA I won't automagically be dumped into whatever comes next. I'd like to give it a little time to steep first.
Not that it's an issue anytime soon -- Bookrown has been out for only 15 months.
