It seems that Wago and WowInterface have an outdated version, and it's not possible to update the addon from Curse, so it would be very nice to add WoWUp support from GitHub, please.

I was seeing that there was already a PR to add this feature #324

Wowup can pull from wago.

There is a wago addon for details damage meter. Search there. It is currently up to date.

#309 (comment) has a solution.
