• Added Unity 6.5 GetEntityId/GetInstanceId support.
• Added NetworkCollider2D use PhysicsScene2D.OverlapCollider as a fallback (#1042).
• Added NetworkCollider/2D.RemoveEnteredCollider.
• Added NetworkCollider/2D InvokeStayOnEnter.
• Added NetworkAnimator channel option - under Beta menu, Animator Channel (#1039).

4.7.2R

• Fixed NetworkTickSmoother.FavorNetworkTransform missing from the inspector.
• Fixed garbage collection in NetworkCollider/2D on server/host.
• Fixed garbage collection ObjectCaching due to ConcurrentStack internal collections being discarded.
• Changed removed threading Tugboat socket start/stop to support ObjectCaching changes.
• Changed: Use new() over new Explicit().
• Added BETA Synapse Transport/Socket: 5a01d2640255d31db51d595ab3a5a8eab8ee769a

4.7.1R

• Fixed prediction level of detail(LOD) incorrectly using the closest LOD when multiple LOD objects were present.
• Fixed null check missing on networkManager in ObserverManager.UpdateLevelOfDetails.
• Changed organized several files to correct folders.
• Added NetworkObject.LocalLevelOfDetailCalculationType(Prediction tab).

4.7.0R

• Fixed NetworkTrigger/Collider incorrectly updating states during replays, resulting in collider Enter callbacks invoking unexpectedly.
• Fixed PredictionRigidbody/2D pending forces conflicting with NetworkTrigger/Collider interactions.
• Fixed Local States not being used as reconcile data when remote states were unavailable.
• Fixed overflow vulnerability with SplitReader.
• Fixed memory allocation attack via packet fragmentation in LiteNetLib (#1026).
• Fixed Buffer ArgumentNullException (#1021).
• Fixed cecil errors commonly seen as xyz not imported (#1023).
• Changed (break) NetworkCollider/Trigger now provides Tick as well. Callbacks must be updated to include 'uint tick'.
• Changed reverted objects deinitializing during OnDisable. This change prior caused NullReferenceExceptions for some when reloading scenes.
• Improved additional sanity checks added when an object becomes intialized twice without first deinitializing.
• Added ObserverManager Level of Detail. This feature currently supports prediction reconciles -- improving both server and client performance and bandwidth.
• Added NetworkObject.UseLevelOfDetail.
• Added NetworkObject AddComponentMenu (#1022).
• Added TransportManager.MaximumClientPacketSize.

4.6.22R

• Fixed removed 'useLocalSpace' references from MovementSettingsDrawer (#1019).
• Changed Beta ReplicateStates moved into Stable; old states have been removed.

4.6.21R

• Fixed MovePosition/Rotation being unintentionally cleared with velocities (#1009, #1010).
• Fixed NetworkCollider disposing of rather than pooling some collections, resulting in garbage collection.
• Fixed NetworkTrafficStatistics initializing when disabled; this did not result in tracking but did have a neglible runtime performance impact.
• Fixed NetworkTransform.GetChanged including non-synchronized properties (#1016).
• Fixed missing error log when exceeding NetworkBehaviour limit pet NetworkObject.
• Fixed prefab searching being done recursively despite being set not to (#1005 #1015).
• Fixed ObserversRpc.BufferLast not handling ExcludeOwner (#985).
• Fixed smoothers AttachOnStop not working (#1018).
• Improved NetworkTrafficStatics uses TryGetBidirectionalNetworkTraffic rather than assume value is not null. This is to resolve a Unity bug where fields lose value during debug inspection (#1000).
• Improved added additional ProfileMarkers to PredictionManager.
• Improved NetworkTransform performance marginally (#989).
• Improved added ProfileMarkers to ClientManager, ClientObjects/.RpcLinks, NetworkTransform (#989).
• Improved Writer.WriteGuidAllocated obsoleted. Allocations have been removed; use WriteGuid instead (@belplaton).
• Improved added INetworkConnectionBroadcast interface to allow broadcast mocking (#1007).
• Added ManagedObjects.OnSpawnedAdd/Remove/Clear events (#989).
• Added Beta Threaded TickSmoothers (contribution by https://github.com/belplaton)
• Added Beta Threaded Collider Rollback (contribution by https://github.com/belplaton).
• Added ability for NetworkTrafficStatistics to run in headless builds (#1004).

4.6.20R

• Fixed NetworkObject.GraphicalObject smoother not working as clientOnly.
• Fixed replicates from clients not running on server when using Inserted prediction order.
• Fixed TimeManager simulates calling SyncTransforms on Physics2D rather than Physics2D.Simulate.
• Added NetworkTickSmoother.FavorPredictionNetworkTransform. As true this disables smoothing when the NetworkObject enables prediction, specifies a NetworkTransform to use, and that NetworkTransform is currently smoothing.
• Fixed tick smoothers interferring with NetworkTransform when EnableStateForwarding was disabled.
• Fixed Prediction.Rigidbody demo creating reconcile in OnTick rather than OnPostTick.

4.6.19R

• Fixed rigidbodies never settling on clients often resulting in very subtle shaking and excessive replicate/reconcile sends.
• Fixed WriteUnsignedPackedWhole ensuring 9 bytes rather than 10, very rarely causing out of bounds exception when writing large numbers.
• Fixed replayed replicates executing 1 tick early.
• Improved notes within CharacterControllerPrediction demo script.
• Improved upgraded internal API for Unity 6.
• Added NetworkObject.LocalReconcileCorrectionType when using physics prediction; this repairs rigidbody drifting during replays due to non-deterministic physics.

4.6.18R

• Fixed parent NetworkBehaviour finding error during serialization.
• Fixed NullReferenceException when a NetworkObject was being automatically added during serialization.
• Fixed TickSmootherController incorrectly calling OnUpdate when OnPreTick was intended, breaking smooting components.

4.6.17R

• Fixed ObjectCache collections not being initialized due to multi-threading support for Unity 6+.
