In versions 14.0.8 and 14.5.0 of Spotfire, new functionality has been added to make it easier to manage licenses and license features. Because of underlying changes to how the licenses work, you must upgrade the Spotfire Server before you deploy the new Spotfire client package and update your installed clients and Web Player services.
