The plugin is the full implementation of a pure-Grails Content Management System that you can embed into your own Grails applications. You can create customized CMS functionality or a hybrid application/CMS to provide user-editable content in production. Security is completely decoupled so that you can plug in whatever security mechanism you are using, and you can customize the look and feel of the user interface to suit your application.
It is now compatible with Grails 2.4.x, current released version: 1.4 release notes
