### <mark style="color:blue;">1.3.1</mark> <a href="#id-1.2" id="id-1.2"></a>

Published 18.10.2024

#### Added

* Error log in the connection when sending more bytes than the specified MTU.
* Moved AutoSimulatorConnection from Coherence.UI into Coherence.Simulator.
* Avoid postprocessing assets on clones.
* Extended Project window icon to inform about more problems with project configuration.

#### Changed

* Changed `ICoherenceBridge` interface from `Entity UnityObjectToEntityId(CoherenceSync from)` to `Entity UnityObjectToEntityId(ICoherenceSync from).`
* Changed `ICoherenceSync` interface to add accessors for the `transform` and `gameObject` property which is in line with the `CoherenceSync` behaviour.

{% hint style="warning" %}
Both changes above are considered potentially breaking changes.
{% endhint %}

#### Fixed

* EntitiesManager now catches any exceptions thrown by user code during disconnection handling, ensuring that the clean up process will finish up properly even if this happens.
* Fixed issue with offline commands not working if CoherenceBridge was `null`.
* WebGL build reliability improved.
* Fixed ArgumentNullException in CoherenceSync Editor when a CoherenceSync component was attached to a Prefab instance.
* Fixed issue where inspecting a CoherenceSync component using Debug Mode while in Edit Mode, could result in a NullReferenceException when later entering Play Mode.
* Fixed the validation to allow *Only predict with input authority* to be selected if a CoherenceInput was attached to a Game Object.

## 1.3 <a href="#id-1.2" id="id-1.2"></a>

Published 17.09.2024

Check out the highlights in our [1.3 blog post](https://coherence.io/blog/news/coherence_1.3) and leave feedback in the [forum thread](https://community.coherence.io/t/release-notes-1-3/588/1)!​
{% endhint %}

**Added**

* Sync attribute has a new `DefaultSyncMode` property to configure `SyncMode` on the binding.
* Invalid command bindings are reported on recompile. Warnings and errors are shown in the console if a method containing an invalid signature is decorated with a `CommandAttribute`.
* A new property called `EnableClientConnections` has been added on `CoherenceBridge`. This replaces the g`lobalQueryOn` field and `GlobalQueryOn` property. They have both been marked as **obsolete** and **should not be used** moving forward.
* Added a new main menu item *coherence > Help > Report a Bug...* that can be used to auto-generate a diagnostics file, which can be shared with **coherence** to help with debugging an issue.
* If the flag `Application.runInBackground` is not `true` a warning is written to the console when the game is played in the Editor.
* Extended the `CoherenceSync` Editor with the ability to detect more undesired Prefab overrides in Prefab instances, and display a warning box and a button to automatically fix them.

**Changed**

* It is no longer necessary to manually add/remove COHERENCE\_LOG\_TRACE and COHERENCE\_LOG\_DEBUG defines. Those are now automatically added/removed when LogLevel is changed.
* Optimized `CoherenceSync.Awake()` and `CoherenceSync.OnEnable()`.
* Moved `RuntimeInterpolationSettings` from `Binding` to `ValueBinding.Interpolator`, changing the type from `InterpolationSettings` to `BindingInterpolator<T>`
* Network packets now contain an end marker for better integration with 3rd party relays.
* `CoherenceBridge.EnableClientConnections` property replaces the `CoherenceBridge.globalQueryOn` field and the `CoherenceBridge.GlobalQueryOn` property.
* Obsolete methods can still be used as commands if adorned with the CommandAttribute.
* Reduced the bandwidth overhead of creating entities \~30 bytes per entity.
* Updated engine version to v6.5.0
* Removed `schemaID` field from `RuntimeSettings` to stop it changing every time the application is baked. The `SchemaID` property of `RuntimeSettings` is still public but is now read-only.
* Removed `CalcSHA1Hash()` from `Schema.`
* Replication Server endpoint for local simulator builds is stored between sessions.

**Fixed**

* NullReferenceException on ArchetypeComponent (Prefabs using LODs).
* NullReferenceException while changing variable or method settings on the Configure window.
* Hub: account name label could wrap the last character unnecessarily.
* Hub: cloud status label could word wrap unnecessarily.
* Reparenting after gaining authority could be reverted.
* Project settings: Disable connection timeout not working with rooms.
* Quaternion interpolation jittering.
* Cleared up the error messages in CoherenceInput to show if the scene needs baked or there is a missing CoherenceBridge.
* NullReferenceException on instantiating two copies of the same prefab using addressables in the same frame.
* Replicated prefabs loaded via addressables could lose commands sent to them from the authority.
* Fix observed interpolation jitter when instantiating and immediately changing the position of an entity with a large delta.
* Removed an error that appeared in the console when a fresh, unbaked, project was opened.
* `Coroutine couldn't be started` error when asynchronously unloading a scene containing a coherence bridge with a client connection.
* Changed the ´Is Kinematic´ component action for Rigidbody and Rigidbody2D to have ´Enable On Authority´ enabled by default. This most likely results in the desired behaviour.
* Library folder no longer appears alongside application when running a stand alone app
* Fixed auto-adoption of orphaned entities with 'Simulate In' set to 'Server Side With Client Input'.
* Added missing method to custom instantiator template
* Fixed game object title bar text being difficult to see when using Light skin.
* Removed error message logged to the console if Android build tries to bundle replication server
* Fixed path to `/UI/icons/Loader anim.png` from absolute to relative
* Fixed issue where position bindings could get removed from nested coherence sync objects.
* Samples browser shows correct thumbnail when opened
* Possibility of entity being created with old binding values in bad network conditions.
* Fixed issue with parenting and changing the floating origin in the same packet causing the child position to be wrong.
