 ## Notices
+- **2022/05/05**: **Breaking change**. `progress()` no longer escapes `%` in the returned string. If
+  you were using `progress()` or `status()` in your `statusline` option, you should wrap the
+  expression inside `%{}` to escape `%`. See [below](#all-together-now) for an example.
 - **2021/03/13**: Some users report success using the Google "Noto Emoji" font for `status_symbol`
   and `indicator_hint`.
 - **2020/11/19**: Please note that the default diagnostics symbols require Font Awesome or a [Nerd
