 ## Features
 
+- Implement `--unbuffered` mode for streaming input, allowing partial lines to display immediately (e.g. `tail -f | bat -u`). Closes #3555, see #3583 (@mainnebula)
 - Added an initial `flake.nix` for a ready made development environment; see #3578 (@vorburger)
 - Add `--quiet-empty` (`-E`) flag to suppress output when input is empty. Closes #1936, see #3563 (@NORMAL-EX)
 - Improve native man pages and command help syntax highlighting by stripping overstriking, see #3517 (@akirk)
