+# [v0.2.1](https://github.com/rhysd/tui-textarea/releases/tag/v0.2.1) - 01 Oct 2023
+
+- [ratatui](https://crates.io/crates/ratatui) crate is supported in addition to [tui-rs](https://crates.io/crates/tui). The ratatui crate is a community fork of inactive tui-rs crate. ([#12](https://github.com/rhysd/tui-textarea/issues/12))
+  - The latest version of ratatui v0.23 is supported.
+  - tui-textarea still uses tui-rs by default to keep the compatibility at this moment. ratatui users explicitly need to set features for it. See [the installation document](https://github.com/rhysd/tui-textarea#installation) for the features matrix. For example, when you want to use ratatui and crossterm, write the following in your `Cargo.toml`:
+    ```toml
+    [dependencies]
+    ratatui = "*"
+    tui-textarea = { version = "*", features = ["ratatui-crossterm"], default-features = false }
+    ```
+  - tui-rs is no longer maintained and the repository was archived. At the next minor version bump, tui-textarea will switch the default features from tui-rs to ratatui. If you use tui-rs, I recommend to switch your dependency to ratatui and to prepare for the version bump.
+  - Examples with ratatui are added to [the `examples` directory](https://github.com/rhysd/tui-textarea/tree/main/examples). For example, the following command runs ratatui version of `editor` example:
+    ```sh
+    cargo run --example ratatui_editor --no-default-features --features=ratatui-crossterm,search file.txt
+    ```
+- Add support for the placeholder text which is rendered when no text is input in the textarea. ([#16](https://github.com/rhysd/tui-textarea/issues/16), thanks [@pm100](https://github.com/pm100))
+  - Use `TextArea::set_placeholder_text` to set the text. To change the text style, use `TextArea::set_placeholder_style`. See [the documentation](https://docs.rs/crate/tui-textarea/latest) for more details.
+  - `popup_placeholder` example was added to show the usage.
+    ```sh
+    cargo run --example popup_placeholder
+    ```
+- Derive `Debug` trait for `TextArea` struct. ([#23](https://github.com/rhysd/tui-textarea/issues/23))
+- Fix a key input is received twice on Windows. ([#17](https://github.com/rhysd/tui-textarea/issues/17), thanks [@pm100](https://github.com/pm100))
