+- Support mouse scroll. ([#2](https://github.com/rhysd/tui-textarea/issues/2))
+  - Handle mouse events for both `crossterm` and `termion` backends.
+  - `TextArea::scroll` method was added.
+  - `Key::MouseScrollUp` and `Key::MouseScrollDown` virtual keys are added to `Key` enum so that custom backends can support mouse scrolling.
+  - `CursorMove::InViewport` variant was added to `CursorMove` enum, which ensures  the cursor to be within the viewport
+- Add `TextArea::alignment` and `TextArea::set_alignment` to set the text alignment of textarea. Note that right or center alignments don't work well with line number so `TextArea::set_alignment` automatically disables it. ([#3](https://github.com/rhysd/tui-textarea/issues/3), thanks [@Volkalex28](https://github.com/Volkalex28))

+- Set [`rust-version`](https://doc.rust-lang.org/cargo/reference/manifest.html#the-rust-version-field) to 1.56.1 in `Cargo.toml` to show MSRV explicitly.

 - Add `arbitrary` feature which is disabled by default. By enabling it, `Input`, `Key` and `CursorMove` can be randomly generated via [arbitrary](https://crates.io/crates/arbitrary) crate. This feature aims to be used by fuzzing tests.
 - Add many benchmark suites to track performance; insert/delete lines/characters, text search, moving a cursor.
 - Improve fuzzing tests to include rendering a textarea to a dummy terminal backend and moving a cursor randomly.
-- Refactor `TextArea` implementation. The implementation of text search was separated to `src/search.rs`. The implementation of highlighting was separated to `src/highlight.rs`. And the implementation of widget rendered by tui-rs was separated to `src/widget.rs`. There is no public API change by these refactorings.
