+- Support the [termwiz](https://crates.io/crates/termwiz) backend for ratatui. `ratatui-termwiz` feature was newly added for this.
+  - Add the following dependencies in your Cargo.toml to use termwiz support.
+    ```toml
+    termwiz = "0.20"
+    ratatui = { version = "0.23", default-features = false, features = ["termwiz"] }
+    tui-textarea = { version = "0.2.4", default-features = false, features = ["ratatui-termwiz"] }
+    ```
+  - Read and run [the `termwiz` example](https://github.com/rhysd/tui-textarea/blob/main/examples/termwiz.rs) to know the API usage.
+    ```sh
+    cargo run --example termwiz --no-default-features --features=ratatui-termwiz
+    ```
