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.
Another big change is that we have upped the minimum required PHP version to run our skins and plugins to PHP 7.1. The previously supported version (5.6) is very old and we can't continue developing for it. If you're still using one of the outdated versions of PHP, we encourage you to upgrade to at least PHP 7.3, since this is the minimum version required the upcoming Roundcube 1.6.
