[2.2.0] - 2024-12-12

Added

• Added NetworkObject.OwnershipStatus.SessionOwner to allow Network Objects to be distributable and only owned by the Session Owner. This flag will override all other OwnershipStatus flags. (#3175)
• Added UnityTransport.GetEndpoint method to provide a way to obtain NetworkEndpoint information of a connection via client identifier. (#3130)
• Added NetworkTransport.OnEarlyUpdate and NetworkTransport.OnPostLateUpdate methods to provide more control over handling transport related events at the start and end of each frame. (#3113)

Fixed

• Fixed issue where the server, host, or session owner would not populate the in-scene place NetworkObject table if the scene was loaded prior to starting the NetworkManager. (#3177)
• Fixed issue where the NetworkObjectIdHash value could be incorrect when entering play mode while still in prefab edit mode with pending changes and using MPPM. (#3162)
• Fixed issue where a sever only NetworkManager instance would spawn the actual NetworkPrefab's GameObject as opposed to creating an instance of it. (#3160)
• Fixed issue where only the session owner (as opposed to all clients) would handle spawning prefab overrides properly when using a distributed authority network topology. (#3160)
• Fixed issue where an exception was thrown when calling NetworkManager.Shutdown after calling UnityTransport.Shutdown. (#3118)
• Fixed issue where NetworkList properties on in-scene placed NetworkObjects could cause small memory leaks when entering playmode. (#3147)
• Fixed in-scene NertworkObject synchronization issue when loading a scene with currently connected clients connected to a session created by a NetworkManager started as a server (i.e. not as a host). (#3133)
• Fixed issue where a NetworkManager started as a server would not add itself as an observer to in-scene placed NetworkObjects instantiated and spawned by a scene loading event. (#3133)
• Fixed issue where spawning a player using NetworkObject.InstantiateAndSpawn or NetworkSpawnManager.InstantiateAndSpawn would not update the NetworkSpawnManager.PlayerObjects or assign the newly spawned player to the NetworkClient.PlayerObject. (#3122)
• Fixed issue where queued UnitTransport (NetworkTransport) message batches were being sent on the next frame. They are now sent at the end of the frame during PostLateUpdate. (#3113)
• Fixed issue where NotOwnerRpcTarget or OwnerRpcTarget were not using their replacements NotAuthorityRpcTarget and AuthorityRpcTarget which would invoke a warning. (#3111)
• Fixed issue where client is removed as an observer from spawned objects when their player instance is despawned. (#3110)
• Fixed issue where NetworkAnimator would statically allocate write buffer space for Animator parameters that could cause a write error if the number of parameters exceeded the space allocated. (#3108)

Changed

• In-scene placed NetworkObjects have been made distributable when balancing object distribution after a connection event. (#3175)
• Optimised NetworkVariable and NetworkTransform related packets when in Distributed Authority mode.
• The Debug Simulator section of the Unity Transport component was removed. This section was not functional anymore and users are now recommended to use the more featureful Network Simulator tool from the Multiplayer Tools package instead. (#3121)
