 # CHANGELOG
 
+## 1.1.0 - 2016-07-22
+
+This release introduces support for running `composer install --classmap-authoritative`
+and `composer install --no-scripts`. Please note that performance
+while using these modes may be degraded, but the package will
+still work.
+
+Additionally, the package was tuned to prevent the plugin from
+running twice at installation.
+
