I am finding it hard to select between Wordpress, Joomla, Drupal or any other CMS that can link with OpenERP (Mostly because out of date). My issues are:

Up-To-Date. Most are very old and almost a year old without any update. Features. There are several features not available. API or option for custom configuration. Finding a way to customize or enhance the integration between OpenERP and the CMS. Ease of use. I had to modify at least 3 files manually in other to implement this for a particular CMS. So an easy way to implement this and start working would be nice. With this points in mind I ask:

Which one would be the recommended to use for OpenERP 7.x and soon to be OpenERP 8.x (Trunk) that it allows me to show my clients the information they need and allows the administrators to manage what they need with ease.
