+### New Features

+* The **Installed Unity Games** window
+  ([InstalledUnityGamesWindow](Editor/Core/Windows/InstalledUnityGamesWindow.cs))
+  now reports each game's render pipeline
+  * A **Pipeline** column shows `BiRP`, `URP`, `HDRP`, `Custom`, or `?`, inferred

+    metadata-only stubs
+
 ### Fixes
