I use @Garkin 's update of Srendarr. Afaik, it is updated to include the new API functions (at least it displays a shipload of information now, way more than before) and it works like a charm.

Ah, didn't see that... Thought it was already updated.

But yes, it works, no errors no nothing. Maybe @Garkin could update us on whether he will publish another update in lieu of the original author...

It seems that patches don't always affect all addons. Some of mine have been showing as out of date since I got them and they still work perfectly.

I've not thoroughly tested it but Srendarr seems to be working as normal with the new build, and it's definitely my favourite for showing buffs and debuffs - mainly because it blends in well with the default UI and it's highly customisable.

I also just want to take this time to say that finding a way to track buff/debuff durations shouldn't be this hard. I hope @ZOS_RichLambert is my hero and eventually ushers in some of those UI improvements. You can make them minimal and still fit the simplistic UI so well (think SkyUI style for the buff/debuff timers).

Buff/Debuff timers
Mouseover tooltip information for all of the things. Seriously. There's so many buffs and effects we get hit with that say nothing in their tooltip that they might as well just say "???" in them instead of the name of the effect.

^ All I want. I don't even care about nameplates unless they keep track of debuffs I apply to enemies somewhere on them.

edit: Added bonus for also letting us move UI elements (example: unlocking and dragging the quest tracker window somewhere else, or moving the resource bars more center screen if we want, etc).
