  • CoherenceSync: added support for nested Prefabs and hierarchies via PrefabSyncGroup component.

  • Sample: matchmaking with manual authentication.

  • CoherenceBridge: added ability to disconnect from within the inspector.

  • CoherenceSync: added support for byte, sbyte, short, ushort and char.

  • CoherenceSync: Configure window shows variables and methods tagged with [Sync] and [Command].

  • CoherenceScene: editor scene visibility settings split for Clients and Simulators.

  • Reworked interpolation. Removed overshoot settings.

  • Reworked code generation. Now, it's implemented on the Unity/C#-side.

  • Updated JWT implementation, which is no longer provided as a pre-build DLL. This also prevents dependency conflicts.

  • HTTP request timeout changed from 1 second to 10 seconds.

  • Multi-Room Simulators Wizard: reworked, simplified layout.


  • Game Object getting deselected after adding CoherenceSync.

  • Reduced the amount of GC allocs made for better performance.

  • Release WebSocket when leaving Play Mode.

  • Instantiated InterpolationSettings never getting destroyed.

  • Time scale related issues, including jitter and low-FPS scenarios.

  • Restrict and warn about the 31 components per entity limitation.

  • Resolve inheritance when sending commands.

  • Client Connection Prefab instances initialization issue when using the CreateScene API.

  • Issue where mixing Transform and RectTransform networked variables could break.

  • Console error after baking when Upload Schema on Baking Complete was on.

  • Profiler: count messages received.

  • Sample: wasn't refreshing Worlds properly in some scenarios.

  • CoherenceSync: deleting a Component or a GameObject on the hierarchy spammed errors on the console.

  • Uploading WebGL builds now shows the correct information on the progress bar.

  • Console errors after deleting a Prefab, when the Coherence Objects Window has been opened and closed.


  • Unity 2020 support. (Minimum supported version is now Unity 2021.3 LTS)


Published 06.10.2023


  • Extrapolation: Max Overshoot Allowed range increased to [0, 20].

  • Extrapolation: Expose stale factor (defaults to 2).


  • Highly reduced GC allocs made while serializing.


  • WebSocket request timings.

  • OnValueSynced not triggering when the update packet came with a parenting change.

  • Shifting the floating origin now correctly shifts rigidbodies in the same frame without kicking in the physics interpolation.


Published 05.09.2023


  • Descriptor Providers: two new properties were added to Bindings, called OverrideGetter and OverrideSetter. Setting this to true will allow you to write custom code blocks in your getters and setters, as opposed to being limited to "UnityComponent.{myCustomCode}".

  • CoherenceBridge API: TranslateFloatingOrigin(Vector3d) overload.


  • Floating Origin: fixed entities jittering on remote clients when Floating Origin is changed.


Published 11.08.2023


  • Tutorial Project: Released the Campfire Tutorial Project where you will be able to delve into more advanced aspects of how to use coherence.

  • Force re-cache SchemaID after writing Gathered.schema to disk.


Published 25.07.2023


  • Commands: fixed trying to send a command from an inherited class that is bound in the parent class.

  • Bindings: fixed rare cases where RectTransform bindings would be reported as missing.

  • Client Connection Prefabs: fixed Client Connection instances duplication when changing Physics scene.

  • Coherence Profiler: fixed count of messages received.

  • ReplicationServerRoomsService: fixed RemoveRoom methods.

  • Optimize window rendering issue where rows would disappear.
