NetworkIdentity.AssignClientAuthority and RemoveClientAuthority now send this message instead of a SpawnMessage, so transform data is no longer reset to server values, so no more snap-back of moving objects.SyncDictionary can now be declared and initialized from an existing List.ILPostProcessor is now used for Unity versions 2020.3 and later.NetworkManager.ServerChangeScene now aborts if scene change already in progress.hasAuthority is now properly cleared on client when unspawning scene objects.NetworkMatch components, and no longer throws Key not found exception in certain cases.NetworkManager.StopClient no longer fires twice in certain cases.NetworkMatch was missing attributes.NetworkLoop static class is now public.NetworkConnection.observing is now public.NetworkTransformV2 default values updated. interpolateScale also defaults to false now.NetworkTransformV2 isClientAuthority now protected instead of private.NetworkTransformV2 now using default values.NetworkManager Script Template.componentIndex is now a byte in CmdMessage and RpcMessage structs.SyncObject is now a class instead of an interface.SyncObject.Flush - Use ClearChanges instead.NetworkBehaviour.getSyncVarHookGuard - Use GetSyncVarHookGuard instead.NetworkBehaviour.setSyncVarHookGuard - Use SetSyncVarHookGuard instead.NetworkBehaviour.SetDirtyBit - Use SetSyncVarDirtyBit instead.NetworkServer.SendToReady - Use SendToReadyObservers instead.GUIConsole for easier debugging.UnpackAndInvoke now throws error and disconnects in case of missing handlers.NetworkServer/NetworkClient now detects ever-growing batches.ILPostProcessing in Unity 2020+.NetworkTransformV2.NetworkTransformBase.OnDrawGizmos now only runs in play mode.using to Network Manager template.OnGUI calls are now wrapped in #if UNITY_EDITOR || DEVELOPMENT_BUILD.NetworkEarlyUpdate/NetworkLateUpdate in NetworkLoop now exposed via Action events.NetworkIdentity.spawned has been split into NetworkServer.spawned and NetworkClient.spawned.OnSpawned / OnDestroyed events.OnServerError and OnClientError overrides. Transports still need to implement their part.ZigZag VarInt added back to Compression module.StopDiscovery when stopping server/host/client.NetworkTime.lastPingTime is now reset properly.NetworkBehaviour dirty check uses double time.NetworkTime.UpdateClient uses double precision time for accuracy over days/weeks.NetworkAnimator uses double precision time for accuracy over days/weeks[Command] attribute to NetworkAnimator.CmdSetAnimatorSpeed. DestroyObject is now called when cleaning up scene identities too. Sends unspawn messages and calls OnStopClient/OnStopServerproperly.hasAuthority when destroying and call OnStopAuthority.NetworkManager.isNetworkActive is now a readonly bool.NetworkManager.ConfigureServerFrameRate renamed to ConfigureHeadlessFrameRate.NetworkServer / NetworkClient OnConnected / OnDisconnected events now public so custom Network Managers can hook into them.NetworkServer / NetworkClient Shutdown now correctly clears OnConnected / OnDisconnected event handlers.OnClientDisconnect wasn't being called for host client.SetHostVisibility overwriting.networkBehaviours array is null.NetworkIdentity.Awake when parent is inactive.OnClientChangeScene was not firing for host client.UnpackAndInvoke.WriteUri and ReadUri.FinishLoadScene should not be called when customHandling is true (Additive Scenes).clientAuthority is now public in NetworkRigidbody / NetworkRigidbody2D.ServerAuthFailed bool to Basic Authenticator.NetworkIdentity default script execution order set to -1.OnDisable / OnDestroy.NetworkTransform sync scale and interpolation.NetworkServer.OnDisconnect now calls DestroyPlayerForConnection if NetworkManager doesn't handle it.NetworkClient.Disconnect now checks for null connection and that it's not called twice.NetworkTime now resets when server starts.PlayerUI text corrected.NetworkConnection parameter removed from Network Authenticator's Client messages.MessagePacking GetId<T> return value changed to ushort.Transport.ServerDisconnect return is now void instead of bool.PersistNetworkManagerToOfflineScene to Network Manager...see tooltip.targetFramerate like headless serversNetworkTransform now has the following features:Library/ScriptAssemblies folder and IL2CPP cacheNetworkIdentity.isLocalPlayer is only set, but never reset. Fixes a bug where isLocalPlayer would be false in OnDestroy, so some components couldn't rely on it in OnDestroy.NetworkIdentity.Reset now resets isLocalPlayer after the isLocalPlayer /ClearLocalPlayer check.NetworkIdentity.OnDestroy now only clears NetworkClient.localPlayer if we are still the local player.StopClient.SyncVar field label not shown in Unity 2020 versions (Unity bug).OnServerAddPlayer now adds the connection id to the object name (on the server only, not synced to clients).NetworkTime were renamed. The previous field names are still there and obsolete and will be removed in a later version.ClientScene is now obsolete, use same or similar properties in NetworkClient instead. ClientScene will be fully deprecated and removed in a later version.NetworkClient.RegisterHandler overload that included a NetworkConnection is now obsolete and will be removed in a later version. Handlers can use NetworkClient.connection directly.ClientScene.onLocalPlayerChanged removed.NetworkIdentity now has isServer / isClientOnly.StopServer / StopClient when offline scene is defined to avoid singleton collision.NetworkEarlyUpdate (before any Update/FixedUpdate)NetworkLateUpdate (after any Update/FixedUpdate/LateUpdate) loopsTickIncoming / TickOutgoing to utilize the new NetworkEarly/LateUpdate functions...minimizes latency.MirrorTransport timeout to 30sec from 5sec to cover scene changes.NetworkServer.SpawnObserversForConnection refactored to support all visibility cases (ForceShown / ForceHidden / Default) and all systems (legacy / new / default).NetworkManager.StopServer/StopClient: avoid NullReferenceException when called in OnApplicationQuit or from tests.NetworkServer.Update: inactive connection check moved into the main connections foreach loop. Eliminates a foreach-connections loop.NetworkServer.Update: separate connections update loop moved into the main loop. Now there is only one connections loop.NetworkManagerHUD.showGUI is now obsolete and will be removed in a later version.SendToClientOfPlayer is now obsolete and will be removed in a later version.LogFactory and logging asset feature removed.ignoreAuthority parameter renamed to requiresAuthority, default true.ClientRpc excludeOwner parameter renamed to includeOwner, default true.ClientScene.spawnableObjects is no longer public.NetworkServer / NetworkClient don't use Connect/Disconnect messages any more. Connect/Disconnect events are raised by the transport instead.OnServerError / OnClientError removed since no transport ever implemented them.NetworkConnection.InvokeHandler as no longer needed.NetworkServer.OnConnected allows for connectionId < 0 now.NetworkRoomPlayer ReadyStateChanged oldReadyState parameter name.
