 ### Additional config
 
 Web support requires `sqlite3.wasm` and `powersync_db.worker.js` assets to be served from the web application. This is typically achieved by placing the files in the project `web` directory.
 
-- `sqlite3.wasm` can be found [here](https://github.com/powersync-ja/sqlite3.dart/releases/download/v0.1.0/sqlite3.wasm)
+- `sqlite3.wasm` can be found [here](https://github.com/powersync-ja/sqlite3.dart/releases)
 - `powersync_db.worker.js` can be found in the repo's [releases](https://github.com/powersync-ja/powersync.dart/releases) page.
