+v5.4.0:
+Fixes:
+
+* Fix IL2CPP build crash on Unity 6000.0.x caused by types implementing multiple closed versions of the same generic interface, which triggered a KeyNotFoundException in IL2CPP's vtable builder (VTableBuilderComponent.OverrideInterfaceMethods). An example exception looked like this:
+
+System.Collections.Generic.KeyNotFoundException: The given key 'TDto StreamChat.Core.LowLevelClient.ISavableTo1<StreamChat.Core.InternalDTO.Models.PushNotificationSettingsInternalDTO>::SaveToDto()' was not present in the dictionary.
+
 v5.3.0:
 Features:
