+
+This version of sfn restricts the SparkleFormation library to versions prior to the
+1.0 release. That's great for now but it means many features will not be available
+and only fixes will be backported and applied to this gem.
+
+It is highly suggested that you upgrade to the 1.0 version of sfn or later to take
+advantage of new features and new development. This gem will continue on in
+maintenance mode for the near term future. Once EOL has been reached, this message
+will be updated.
+
+Thanks and happy stacking!
