## CoherenceBridge.GlobalQueryOn -> EnableClientConnections

The **GlobalQueryOn** property on the `Coherence.Toolkit.CoherenceBridge` class has been marked as obsolete, and should no longer be used. If you had references in your code to this property, you should see warnings in your Console about this.

To fix the warnings, update your code to use the **CoherenceBridge.EnableClientConnections** property instead.

## RuntimeSettings.instance -> Instance

The **instance** property on the `Coherence.RuntimeSettings` class has been marked as obsolete, and should no longer be used. If you had references in your code to this property, you should see warnings in your Console about this.

To fix the warnings, update your code to use the **RuntimeSettings.Instance** property instead.

## RuntimeSettings.DefaultTransportMode -> TransportType

The **DefaultTransportMode** property on the `Coherence.RuntimeSettings` class was removed, and replaced with the property **TransportType**.

## Binding.RuntimeInterpolationSettings -> ValueBinding.Interpolator

The **RuntimeInterpolationSettings** property on the `Coherence.Toolkit.Bindings.Binding` class was removed.

A new property **Interpolator** was added to `Coherence.Toolkit.Bindings.ValueBinding`, offering comparable binding interpolation functionality.

## ComponentChange.Mask -> Data.FieldMask

The **Mask** property was removed from the `Coherence.Entities.ComponentChange` struct.

The same value can be acquired using `ComponentChange.Data.FieldsMask` instead.

## ChannelID Relocated

The `Coherence.ChannelID` struct was moved into the `Coherence.Common` assembly.

If you get compile errors about this type not being found, make sure that your [Assembly Definition Asset](https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html) has a reference to the `Coherence.Common` assembly.
