@@ -25,6 +25,8 @@ Changes are grouped as follows:
 - Running the build command, `cdf-tk build`, with a `View` resource with a `hasData` filter would print a
   `UnusedParameterWarning: Parameter 'externalId' is not used in section ('filter', 'hasData', 0, 'externalId').`.
   This is incorrect and is now fixed to not print this warning.
+- If you had a `container` with a direct relation property with a required constraint, the `cdf-tk build` command
+  would incorrectly yield a warning that the `Parameter 'type' is not used ...`. This is now fixed.
