    ```toml
    [dependencies]
-   # Assume that version DuckDB version 0.9.2 is used.
-   duckdb = { version = "0.9.2", features = ["bundled"] }
+   duckdb = { version = "1.3.2", features = ["bundled"] }
    ```
 
 2. When linking against a DuckDB library already on the system (so _not_ using any of the `bundled` features), you can set the `DUCKDB_LIB_DIR` environment variable to point to a directory containing the library. You can also set the `DUCKDB_INCLUDE_DIR` variable to point to the directory containing `duckdb.h`.
