(#3503) - Fixed issue where `NetworkClient` could persist some settings if re-using the same `NetworkManager` instance. (#3491) - Fixed issue where a pooled `NetworkObject` was not resetting the internal latest parent property when despawned. (#3491) - Fixed issue where the initial client synchronization pre-serialization process was not excluding spawned `NetworkObject` instances that already had pending visibility for the client being synchronized. (#3488) - Fixed issue where there was a potential for a small memory leak in the `ConnectionApprovedMessage`.
