Thanks.
I checked ShadowedUnitFrames. He is still polling boss frame updates via OnUpdate. That is because his download is version 3.8.5.
The latest changelog including the clique-shiv and bossframe change is 3.8.6 but that version is not available for download. The download on wowace is working properly:

*edit*
I checked version 3.8.6. He did remove the OnUpdate polling of the boss frames. Not sure if he has any issues though.
