 ## Unreleased
 
+- A new `--list-all` (alias `-a`) flag is now available. It's similar to the
+  exiting `--list` (`-l`) but prints all tasks, even those without a
+  description
+  ([#383](https://github.com/go-task/task/issues/383), [#401](https://github.com/go-task/task/pull/401)).
 - It's now possible to schedule cleanup commands to run once a task finishes
   with the `defer:` keyword
-  ([Documentation](https://taskfile.dev/#/usage?id=doing-task-cleanup-with-defer), [#475](https://github.com/go-task/task/issues/475), [#626](https://github.com/go-task/task/pull/626/files)).

 - Remove long deprecated and undocumented `$` variable prefix and `^` command
   prefix
   ([#642](https://github.com/go-task/task/issues/642), [#644](https://github.com/go-task/task/issues/644), [#645](https://github.com/go-task/task/pull/645)).
