Hi Eva, In the release notes, there is a "What's new" section at the top and the program fixes are listed below that. Release 2018.3 only contained program fixes and no additional features. So if you open the release notes again and look at the "In this document:" navigation section, select "Product Update 3 program fixes". Sorry for the confusion! - Rachel
