+## [Unreleased]
+
+### Added
+
+- By somewhat popular demand, yabridge now comes with yabridgectl, a utility
+  that can automatically set up and manage yabridge for you. It also performs
+  some basic checks to ensure that everything has been set up correctly.
+  Yabridgectl can be downloaded separately from the GitHub releases page and its
+  use is completely optional, so you don't have to use it if you don't want to.
+  Check out the
+  [readme](https://github.com/robbert-vdh/yabridge/tree/feature/cli-tools/tools/yabridgectl/README.md)
+  for more information on how it works.
