+Version 1.14.1 and later of `com.powersync:integration-room` requires [Room 3.0](https://developer.android.com/jetpack/androidx/releases/room3). If your app still uses Room 2.x, upgrade your Room dependency to 3.0 before updating the integration.

 PowerSync acts as an addon to your existing Room database, which means that (unlike with most other PowerSync SDKs)
 you are still responsible for schema management.
 Room requires [raw tables](/client-sdks/advanced/raw-tables), as the views managed by PowerSync are incompatible with

+## Experimental Web Support
+
+Version 1.14.1 of the SDK adds initial support for web targets (JS and WebAssembly). Use `WebConnectionFactory` to open a PowerSync database on the web.
+
+<Warning>
+Web support is experimental and incomplete. We are sharing it for early testing and prototyping purposes, and it is not ready for production use. The main limitation is that multi-tab support is not functional in this version: tabs don't coordinate sync connections or share update notifications, so use the database from a single tab only.
+
+If you try web support, please test it thoroughly and report any issues you run into on [GitHub](https://github.com/powersync-ja/powersync-kotlin/issues). Follow the [tracking issue](https://github.com/powersync-ja/powersync-kotlin/issues/362) for progress on stabilizing web support.

+For a working example, see the web target of the [Supabase To-Do List demo](https://github.com/powersync-ja/powersync-kotlin/tree/main/demos/supabase-todolist).
