On my 2018 Mac Mini, I see AppleIntelKBLGraphics (Kaby Lake) and AppleIntelCFLGraphicsFramebuffer (Coffee Lake) extensions loaded. With macOS 10.14.2 these extensions were both version 18.104.22.168 - with macOS 10.14.3 they are now version 22.214.171.124. We'll probably never know what changed, just an observation I was looking for better monitor wake-from-sleep support. Too early to tell. Curiously, both 126.96.36.199 and 188.8.131.52 have the same Last Modified date of 11/26/18 at 11:31PM - so doesn't bode well for significant changes.
