Hello Rcdarcey 
actually, the tonemapper has been the hottest topic in many many months, its being debated in groups, various forum’s, and other social media.
using search is what anybody should do first anyways.
reading changelogs for updates to the engine should be second nature to a developer.
Additionally, if you are working on a project or just blatantly move to another ue4 version without knowing what changed or why it changed you are potentially setting yourself up for disaster and nobody wants that!
So you could call it condescending, consider how your boss/client would react if you updated without knowing why you updated? or asking questions that have been asked many many times?
See it as future advice instead.
Now I could spend an additional 10 minutes to write all kawaii, change font colors, add a load of smilies but would that add anything? no.
straight to the point, less time wasted on both sides.
