+- [#47](https://github.com/zendframework/zend-router/pull/47) fixes how the `Wildcard` URL assembly works. Previously, it would
+  attempt to `rawurlencode()` all values provided to the method as merged with any default values.
+  It now properly skips any non-scalar values when assembling the URL path. This fixes an issue
+  discovered when providing an array of middleware as a `middleware` default route parameter.
