+## Breaking Changes
+* Update to [Flurl 3](https://github.com/tmenier/Flurl/releases/tag/Flurl.Http.3.0.0). There should be no differences for the end user, but keep in mind.
+
+## Features
+* **Table Splitting**: Ability to use the same database for different document with automatic filtering. ([#106](https://github.com/matteobortolazzo/couchdb-net/issues/106))
+* **Views**: Ability to get views. Thanks to [panoukos41](https://github.com/panoukos41)
+
+## Improvements
+* **Logical Expressions Prune**: If expressions are constant booleans, they are removed automatically keeping the query valid. ([#113](https://github.com/matteobortolazzo/couchdb-net/issues/113))
+* **IsUpAsync**: Returns false on timeout and on not successful codes. ([#107](https://github.com/matteobortolazzo/couchdb-net/issues/107))
+* **FindAsync**: Faster when document is not found. ([#92](https://github.com/matteobortolazzo/couchdb-net/issues/92))

+## Database Splitting
+
+It is possible to use the same database for multiple types:
+```csharp
+public class MyDeathStarContext : CouchContext
+{
+    public CouchDatabase<Rebel> Rebels { get; set; }
+    public CouchDatabase<Vehicle> Vehicles { get; set; }
+
+    // OnConfiguring(CouchOptionsBuilder optionsBuilder) { ... }
+
+    protected override void OnDatabaseCreating(CouchDatabaseBuilder databaseBuilder)
+    {
+        databaseBuilder.Document<Rebel>().ToDatabase("troups");
+        databaseBuilder.Document<Vehicle>().ToDatabase("troups");
+    }
+}
+```
+> When multiple `CouchDatabase` point to the same **database**, a `_discriminator` field is added on documents creation.
+>
+> When querying, a filter by `discriminator` is added automatically.
+
+If you are not using `CouchContext`, you can still use the database slit feature:
+```csharp
+var rebels = client.GetDatabase<Rebel>("troups", nameof(Rebel));
+var vehicles = client.GetDatabase<Vehicle>("troups", nameof(Vehicle));
+```
+
+## Views
+
+It's possible to query a view with the following:
+```csharp
+var options = new CouchViewOptions<string[]>
+{
+    StartKey = new[] {"Luke", "Skywalker"},
+    IncludeDocs = true
+};
+var viewRows = await _rebels.GetViewAsync<string[], RebelView>("jedi", "by_name", options);
+// OR
+var details = await _rebels.GetDetailedViewAsync<int, BattleView>("battle", "by_name", options);
+```
+
 ## Local (non-replicating) Documents
 
 The Local (non-replicating) document interface allows you to create local documents that are not replicated to other databases.
