 ## [Unreleased]
 
+### Added
+
+- Pass the namespace as argument `NAMESPACE` to templated manifests.
+  This should unblock demos to run in all namespaces, as they can template the namespace e.g. for the fqdn of services ([#355]).
+
 ### Fixes
 
 - Use `rustls-native-certs` so that `stackablectl` can be used in environments with internal PKI ([#351]).
