2.1.0

Nightly

Build 1240 (Aug 08, 2025)

Breaking Changes

• NetworkTransform.DisableSharedModeInterpolation option is now a flag enum value
• Prefabs and scenes need to be reimported due to baking changes
• SendReliableDataToPlayer(), SendReliableDataToServer(), OnReliableDataReceived() all now pass ReadOnlySpan<byte> to avoid allocations

What's New

• Fusion Version Scripting Define Symbols: FUSION_2, FUSION_2_1, FUSION_2_1_0, FUSION_2_OR_NEWER, FUSION_2_0_OR_NEWER, FUSION_2_1_OR_NEWER
• NetworkRunner.HasCustomPlugin - returns true if the game is run against a custom plugin
• NetworkRunner.FailedToResolveNetworkObject - an event that can be used to detect cases where [Networked] NetworkObject properties return null not due to underlying NetworkId being zero, but because the object was not found (due to AoI, being destroyed locally etc.)
• NetworkTransform supports the use of physics i.e. Rigidbody or Rigidbody2D in both Shared and Client-Server modes
• Object Priority gives control over the update rate of objects
• [Shared Mode] the size of the Area of Interest cells and the size of the grid can be adjusted in the NetworkProjectConfig
• Added RpcChannel.ReliableLargeData to send RPCs that exceed 512 bytes. Not tick accurate
• NetworkRunner.RequestMasterClientReassign to promote the local player as the master client
• Non-addressable scenes can now also be loaded with NetworkRunner.LoadScene(SceneRef.FromPath(...))
• [Multipeer] Ensure we execute physics for non-default scenes last in FixedUpdate, so this as close to Unity's normal position of running the physics as possible
• FusionUnityHostProfiler - Fusions integration with Unity profiler
• Added FusionMppmCommand.ExecuteAsync
• MatchmakingArgumentsExtensions Utility Methods. Helps to setup MatchmakingArguments for Fusion
• Updated to Realtime SDK 5.1.5
• New Fusion Intro Sample and switch Fusion Menu to standalone
• New Fusion Hub
• NetworkRunner.LocalAddress to access the address Fusion bound to for direct connections
• StartGameArgs.PlayerUniqueId enables reconnects to maintain the same PlayerRef
• Support for breakpoints: ClientServer Mode only. Working on both Multi-Peer and Unity MPPM
• RpcAttribute.InvokeLocalMode. If set to RpcInvokeLocalMode.ForwardToServer, locally invokable RPCs will always be forwarded to the server/plugin from clients

Changes

• RPCs targeted at state authority do not get sent if the local client is the state authority
• Failed to unwrap warning no longer logged for NetworkBehaviour references that fail to resolve, regardless of the reason
• Failed to find behaviour is now logged for an invalid NetworkBehaviour on a valid NetworkObject
• Update to Photon Realtime SDK to 5.1.7
• Clamp PlayerCount to a valid range (1-2048) in Shared Mode
• Clamp Heap PageCount to a valid range (16-4096) in Shared Mode
• Inline help icons added to config's Client/Server Tick/Send rates
• In/out packets statistics reflect packet fragmentation
• Update NanoSockets for Android to support 16 KB page sizes
• OnChangedRender now called at alpha = 0.5 to match interpolators (and reduce perceived latency)
• Unity-provided packages are ignored when looking for assets. To override, define FUSION_ENABLE_SEARCH_IN_UNITY_PACKAGES
• NetworkObjectBaker uses Fusion.Log instead of UnityEngine.Debug
• Check if in Session before leaving it
• Check if connected to Photon Cloud before running disconnect
• Clicking animator bake failure error messages now shows the relevant gameObject in the hierarchy
• Keep Session running only if Host/Server disconnected by Timeout
• Leave Session before disconnect from Photon Cloud
• Removed SendReliableDataToPlayer and SendReliableDataToServer with byte arrays; use overloads with with ReadOnlySpan<byte> instead. Avoids allocation
• Editor trace logs are more granular, with following defines controlling specific streams: FUSION_EDITOR_TRACE_IMPORT, FUSION_EDITOR_TRACE_INSPECTOR, FUSION_EDITOR_TRACE_TEST, FUSION_EDITOR_TRACE_MPPM
• INetPeerGroupCallbacks no longer deal with NetSendEnvelope; NotifyData packet type is assumed and data is passed
• INetworkRunnerCallbacks.OnUserSimulationMessage is now obsolete and no longer used
• SimulationMessage is now obsolete
• Simulation.IsStateAuthority handles PlayerRef.None correctly (i.e. when it represents the host)
• Simulation.IsInputAuthority handles PlayerRef.None and PlayerRef.MasterClient correctly
• Skip opening Fusion Hub in batchmode
• NetworkTRSP state authority change error correction delta default value set to 0
• Assemblies with FUSION_FORCE_WEAVING version define will be weaved even if they are not included in the config's AssembliesToWeave
• Fusion.Unity assembly no longer has to be added to the config's AssembliesToWeave
• NetworkObjectInterestModes made public
• NetworkObject.ObjectInterest internal field renamed to NetworkObject.LegacyObjectInterest; it is used only to migrate to storing interest settings in object flags (handled by the baker)
• Current flag versions set to NetworkObjectFlags.V2. All prefabs and scenes need a rebake
• NetworkObject editor: Prefab Source is now selectable
• NetworkRunner.FindObject/TryFindObject no longer throw if simulation is not started
• NetworkTransform on root NetworkObject is now always placed at index 0, regardless of component order
• Join Session Log to be more clear
• Made NetworkSceneManagerDefault.OnSceneInfoChanged method virtual
• NetworkObjects that remains after shared mode authority leaves now has state authority set to PlayerRef.None
• DestroyWhenStateAuthorityLeaves prefab flag is now independent from the AllowStateAuthorityOverride
• Shared mode master client can now despawn network objects with PlayerRef.None as state authority
• Apply NetworkTransform.DisableSharedModeInterpolation in Single Mode

Removed

• EngineProfiler, the old DLL-side profiler integration
• FusionProfiler, the old Unity-side profiler integration

Bug Fixes

• Fixed: Empty IntrusiveLinkedListNode is now different than the one in a single-element list. This is done by the list always being cyclical
• Fixed: Fusion plugin crashing during stress tests due to the number of RPC to be tracked in an envelope
• Fixed: VisionOS NanoSockets Static Library
• Fixed: Prefabs not being replicated until a resimulation tick occur
• Fixed: MenuItem attribute preventing builds
• Fixed: Reset re-join attempts when peer is able to join Session
• Fixed: Rst item in SimulationConfig (ReplicationFeatures) does not draw it's help correctly in Unity inspector
• Fixed: Object destroys not being resent in case of a packet loss
• Fixed: OnNotifyDataLost ignoring objects/destroys if there haven't been any RPCs in the packet as well
• Fixed: Stop repeated Unity warning logging if simulating multi peer physics scenes by not simulating the default scene
• Fixed: RPCs targeting state authority were not being received when outside the area of interest
• Fixed: Alloc in NetSocketHybrid.Receive
• Fixed: Alloc in TimeSeries.Median
• Fixed: NetworkArray<T>.GetRef throwing NullReferenceException
• Fixed: NetworkBool drawer throwing ArgumentOutOfRangeException
• Fixed: Editor error when interacting with invalid network objects. Header can be uninitialized and causes null ref, checking Ptr to avoid it
• Fixed: Crash in some Unity versions when opening the project in batch mode due to forced recompilation
• Fixed: [Shared Mode] data not being sent to a client if the previous packet has just been acknowledged
• Fixed: Invalid authority checks when destroying hierarchies of NetworkObjects with mixed authorities
• Fixed: Error logged when input authority invokes RPC with state authority target mask
• Fixed: In Shared Mode, if a state authority makes a state change which races against the server removing state authority from it, then flag the original state needing to be re-sent
• Fixed: [Shared Mode] Pending local deletes being ignored when receiving object updates
• Fixed: Shutdown normally if Disconnected By PluginLogic
• Fixed: Use StartGameArgs.Config for PlayerCount, if supplied
• Fixed: Runtime spawned objects in scene are spawned/despawned multiple times in scene unload with a large amount of objects
• Fixed: WriteUsingAreOfInterest not terminating data block properly
• Fixed: Structs state authority not checked before writing
• Fixed: Received objects state authority not checked before applying
• Fixed: Plugin not deserializing private serializable fields of base types
