https://classic.wowhead.com/news=303375/update-your-addons-wow-classic-threat-meters-switch-to-a-new-library
Reason: Original author has dissapeared, this one fixes several bugs and all the major addons (Details/DBM/..) have moved to this one.
This new version does not communicate with the old one.
