 ## [Unreleased]
 
+## [0.3.1] — 2026-08-01
+
+A patch for one bug, shipped on its own because of how it fails. `Notification`
+discarded body content in every theme and both engines, and in django-cotton it
+did so **silently** — no error, no warning, and a call site that reads
+correctly. Anyone using the natural container form has been getting an empty
+box, and nothing in their own code or logs would say so. This predates 0.1.1,
+so every release to date is affected.
+
+Upgrade if you pass children to `<c-cf.notification>` or `<Cf:Notification>`.
+If every call site passes `message=`, nothing changes for you.
+
+Nothing else changed. The JinjaX signature only loosens and the cotton wrapper
+only gains a default, so every existing `message=` call site renders
+byte-identically to 0.3.0. No migration.
+
 ### Fixed — `Notification` silently discarded its body content (#65)
 
 - **Every theme, both engines, rendered the scalar `message` prop and nothing
