 # Changelog
 
+## 1.8.0 (unreleased)
+
+* Enable the `newClientImplementation` by default. This should improve performance and memory usage.
+* **Potential Breaking Change** The `newClientImplementation` now uses WebSockets to connect to the PowerSync service. These WebSockets connections do not log events to `SyncClientConfiguration->requestLogger`.
+* Add the `soft` flag to `disconnectAndClear()` which keeps an internal copy of synced data in the database, allowing faster re-sync if a compatible token is used in the next connect() call
+* Update PowerSync SQLite core to 0.4.10
+* Update Kotlin SDK to 1.7.0.
+
+
 ## 1.7.0
 
 * Update Kotlin SDK to 1.7.0.
