@@ -35,6 +35,7 @@ Enhancements
 * A new `range` function variant that takes an exclusive range with a step.
 * `as_string` is added to BLOB's to convert it into a string by interpreting it as a UTF-8 byte stream.
 * `FnAccess::is_private`, `FnAccess::is_public`, `FnNamespace::is_module_namespace` and `FnNameSpace::is_global_namespace` are added for convenience.
+* `Iterator<Item=T>` type for functions metadata is simplified to `Iterator<T>`.
