All updates and bugs for Xbox One can be found in the Xbox Updates forum area. When you are in the general funcoms forums there is a whole topic for Xbox and then under that a topic dedicated to updates. Here is the one for today’s patch:

The Hotfix is not a patch size of 60GB. Way back when Conan Exiles was first released we would have the game reinstalled each time. They finally figured out how to properly package it up for Microsoft and sized it down. This patch is actually reinstalling the entire game for you, patch and all.
The developers are not respecting that some players have data caps, slower internet, daily jobs, etc and it’s not so nice to have to re-download 60GB when it’s already on your hard drive.
