Yes, I'm certain, did some testing on all of my toons and it's for sure no longer displaying the 1s. As I said, I slowly incremented all types of XP and it works fine (didn't manage to advance Tradeskill XP by such small steps, but it seemed consistent. Didn't display 1s at least).
I can also confirm that the part in front of the "." is still having the rounding error that it always had, there's no change to that.
The DD was reporting the name of the target until LU24, now it's just empty. The tooltip still contains the target, though. LU24 also introduced this annoying flickering of timed maintained spells as they are apparently shown/hidden instead of just updated.
EDIT: And while we're talking about things that are annoying (and that I /bugged to no avail so far), the autoattackeffector will also trigger if you do rangedautoattack. It's annoying because I'm displaying different graphics for both in ProfitUI and they are both showing if you do ranged.
EDIT2: Sorry for hijacking a thread in this forum btw.
