As you may know, the latest version of Roundcube (1.6) has just entered the release candidate stage. We're pleased to announce that we have just released an upgraded version of our skins and plugins that are fully compatible with this new version of Roundcube.
We have also upgraded a few of the plugins, with the News Feed undergoing the biggest changes. Along with improving the way the RSS previews work, we've fixed a potential security vulnerability, so if you're using this plugin, you should upgrade to the latest version as soon as you can.
