 ## Changelog
 
+### 0.9.78 - 15/08/2024
+* `Model.ObserveAll` now returns `IObservable<IChangeSet<ReadOnly, EntityId>>` instead of `IObservable<IChangeSet<ReadOnly, DatomKey>>` which makes it
+easier to use in projects without polluting the code with `DatomKey` references. `Connection.ObserveDatoms` still returns `IObservable<IChangeSet<Datom, DatomKey>>`
+
 ### 0.9.77 - 15/08/2024
 * Added extension methods to query multiple indexed datoms at once. Results from the database are merge-joined into a
 single list that is extremely fast to calculate.
