Not sure this is the right place, but using the "beta-hidden-beard-bathing-dik-dik" release on current beta. (saw a few post about a beta build working) - however get the following error on load and addon does not seem to load.

If you need more info, please let me know - Thanks.

Also, this is with KNP being the only addon loaded.
If there isn't a BFA compatible addon - sorry for my idiocy :)

My guess is that UNIT_POWER was replaced with UNIT_POWER_UPDATE.
Editing line 79 as
self:RegisterUnitEvent('UNIT_POWER_UPDATE','PowerEvent') seems to possibly fix it and load - though names seem to randomly disappear.

Manually install this version for BFA support: https://github.com/kesava-wow/kuinameplates2/tree/bfa. The beta versions on Curse/Twitch are KNP's own betas - it's not referring to wow.
