 ## Unreleased
 
+** multiline text editor **
+
+![multiline editor](assets/multiline-texteditor.gif)
+
+### Breaking Change
+The Commit message popup now supports multiline editing! Inserting a **newline** defaults to `enter`. This comes with a new default to confirm the commit message (`ctrl+d`).
+Both commands can be overwritten via `newline` and `commit` in the key bindings. see [KEY_CONFIG](./KEY_CONFIG.md) on how.
+These defaults require some adoption from existing users but feel more natural to new users.
+
 ### Added
 * `theme.ron` now supports customizing line break symbol ([#1894](https://github.com/extrawurst/gitui/issues/1894))
 * add confirmation for dialog for undo commit [[@TeFiLeDo](https://github.com/TeFiLeDo)] ([#1912](https://github.com/extrawurst/gitui/issues/1912))
 * support `prepare-commit-msg` hook ([#1873](https://github.com/extrawurst/gitui/issues/1873))
+* support for new-line in text-input (e.g. commit message editor) [[@pm100]](https://github/pm100) ([#1662](https://github.com/extrawurst/gitui/issues/1662)).
 
 ### Changed
 * do not allow tag when `tag.gpgsign` enabled [[@TeFiLeDo](https://github.com/TeFiLeDo)] ([#1915](https://github.com/extrawurst/gitui/pull/1915))
