 ### Added
 
-- Nothing.
+- [#19](https://github.com/zfcampus/zf-versioning/pull/19) adds the ability to
+  override the `default_version` setting to specify default versions by route
+  name. As such, the `default_version` value may be one of the following:
+
+  - An integer value, indicating the default version for all APIs.
+  - An associative array of route name keys pointing to their specific default version.
 
 ### Deprecated

 ### Fixed
 
-- Nothing.
+- [#19](https://github.com/zfcampus/zf-versioning/pull/19) fixes a problem with
+  how the `PrototypeRouteListener` handles the `default_version` setting; the

 The `default_version` key provides the default version number to use in case a version is not
 provided by the client.  `1` is the default for `default_version`.
 
+The setting accepts one of the two following possible values:
+
+- A PHP `integer` indicating the default version number for *all* routes.
+- An associative array, where the keys are route names, and the values the default version to use with the associated route.
+
 Full Example:
 
 ```php
+// Set v2 as default version for all routes
 'zf-versioning' => [
-    'default_version' => 1,
+    'default_version' => 2,
+],
+```

+```php
+// Set default version to v2 and v3 for the users and status routes respectively
+'zf-versioning' => [

+        'myapi.rest.users' => 2,
