 ### Fixed
 
+- Fixed regression issue in v2.x where `NetworkObject.GetNetworkBehaviourAtOrderIndex` was converted from public to internal. (#3541)
 - Fixed ensuring OnValueChanged callback is still triggered on the authority when a collection changes and then reverts to the previous value in the same frame. (#3539)
 - Fixed synchronizing the destroyGameObject parameter to clients for InScenePlaced network objects. (#3514)
 - Fixed distributed authority related issue where enabling the `NetworkObject.DestroyWithScene` would cause errors when a destroying non-authority instances due to loading (single mode) or unloading scene events. (#3500)
