 =========
 
+0.25.0
+------
+
+Completely refactors :ref:`Layout Dispatchers <Layout Dispatcher>` by switching from a
+class-based approach to one that leverages pure functions. While the logic itself isn't
+any simpler, it was easier to implement, and now hopefully understand, correctly. This
+conversion was motivated by several bugs that had cropped up related to improper usage
+of ``anyio``.
+
+**Issues Fixed:**
