 ### Removed
 
 * Removed ITrackedInteractor, as it was supporting an unused codepath and there are better ways to get this data (like querying the attach transform). [PR #1044](https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity/pull/1044)
+* Removed FindObjectUtility, as it was a backwards-compatibility layer for pre-2021.3.18. Since our min version is now 2022.3, we can just call the API directly. [PR #1056](https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity/pull/1056)
 
 ### Deprecated
