+  - New application setup hook 'config_for' which allows one to get the
+    canonical application configuration for a controller, view or model, or
+    a plugin.  Can also be used to override and adapt what configuration is
+    retrieved.

 5.90089_003 - 2015-04-27
   - Fixed an issue where a delayed controller that did ACCEPT_CONTEXT would
     raise an error when registering its actions.

+Return the application level configuration (which is not yet merged with any
+local component configuration, via $component_class->config) for the named
+component or component object. Example:
+
+    MyApp->config(
+      'Model::Foo' => { a => 1, b => 2},
+    );
+
+    my $config = MyApp->config_for('MyApp::Model::Foo');
+
+In this case $config is the hashref C< {a=>1, b=>2} >.
+
+This is also handy for looking up configuration for a plugin, to make sure you follow
+existing L<Catalyst> standards for where a plugin should put its configuration.
