File changes not displayed, nor listed

The build history tab used to display the number of file changes in the list of builds. Now it only displays changes in build configuration settings. It says ‘no changes’, but my auto build project is still triggered, and I believe that can only happen due to changes detected in source control. Also there are no file changes listed in the Changes tab when the build is selected.

Unity version: latest 5.6
Xcode: latest
Source control: svn
Build target: iOS
Project name: Cuby Road

I assume you are looking at the " iOS - Adhoc Release" target? The way the changes are calculated currently is by looking at the changes between the current build and the last SUCCESSFUL build (which I realize is not necessarily what most developers are expecting there). Since that target hasn’t had any successful builds the “files changed” will continue to show empty.
