The Problem
If you edit branch-versioned feature service data in ArcGIS Pro, you've probably had that moment of dread wondering whether you just made edits on the Default version instead of a child branch version. As mentioned in this RHUG Community post by Kevin Hunt, it is easy to accidentally make an edit to the Default version.
The Solution
MnDOT has developed "Default Version Guard" - an add-in for ArcGIS Pro that alerts and attempts to block edits to branch-versioned, feature services that are pointing to Default in your active map window. You can find the download for the add-in below. Once downloaded, double-click the .esriAddinX file to install in ArcGIS Pro.
