 ## Unreleased
 
+## 1.3.0
+
+- When testing realtime responses, `realtime: true` must be defined in `SupabaseRequest`. This also resolves a duplicate `emits` bug in tests; the most common resolution is to remove the first duplicated expected response (e.g. `emitsInOrder([[], [], [resp]])` becomes `emitsInOrder([[], [resp]])`)
+- Associations are not serialized in the `SupabaseResponse`; only subscribed table data is provided
+
 ## 1.2.0
 
 - **DEPRECATION** `Query(providerArgs: {'limitReferencedTable':})` has been removed in favor of `Query(limitBy:)`
