This appears to have been updated in January and for Shadowlands 9.0.2.
Unless errors have occurred due to changes introduced by 9.0.5 (none that I am aware of ) or addons using Lightheaded not being updated for Shadowlands ( like tom tom ) or the addon itself changing what and how it does its stuff. That is it.
