+CHANGELOG
+=========
+
+2.7.0
+-----
+
+ * made it possible to configure the default formats for both the `date` and the `number_format` filter
+ * added support for the new Asset component (from Twig bridge)
+ * deprecated the assets extension (use the one from the Twig bridge instead)
+
+2.6.0
+-----
+
+ * [BC BREAK] changed exception.json.twig to match same structure as error.json.twig making clients independent of runtime environment.
+
+2.3.0
+-----
+
+ * added option to configure a custom template escaping guesser (via `autoescape_service` and `autoescape_service_method`)
+
+2.2.0
+-----
+
+ * moved the exception controller to be a service (`twig.controller.exception:showAction` vs `Symfony\\Bundle\\TwigBundle\\Controller\\ExceptionController::showAction`)
+ * added support for multiple loaders via the "twig.loader" tag.
+ * added automatic registration of namespaced paths for registered bundles
+ * added support for namespaced paths
+
+2.1.0
+-----
+
+ * added a new setting ("paths") to configure more paths for the Twig filesystem loader
+ * added contextual escaping based on the template file name (disabled if you explicitly pass an autoescape option)
+ * added a command that extracts translation messages from templates
+ * added the real template name when an error occurs in a Twig template
+ * added the twig:lint command that will validate a Twig template syntax.
