  * The `app` global variable is now injected even when using the twig service directly.
+ * Added an optional parameter to the `path` and `url` function which allows to generate
+   relative paths (e.g. "../parent-file") and scheme-relative URLs (e.g. "//example.com/dir/file").

    pass the requirements (otherwise it would break your link anyway).
  * There is no restriction on the route name anymore. So non-alphanumeric characters
    are now also allowed.
+ * Added possibility to generate relative paths and network paths in the UrlGenerator, e.g.
+   "../parent-file" and "//example.com/dir/file". The third parameter in
+   `UrlGeneratorInterface::generate($name, $parameters = array(), $referenceType = self::ABSOLUTE_PATH)`
+   now accepts more values and you should use the constants defined in `UrlGeneratorInterface` for
+   claritiy. The old method calls with a Boolean parameter will continue to work because they
+   equal the signature using the constants.
