We have tested our skins and plugins on the recently released Roundcube 1.3.4, and we're pleased to announce that they are all fully compatible and don't need to be upgraded. So if you're planning to upgrade to the latest version of Roundcube and you're using the latest version of our software, you can do it safely and your current versions of the skins and plugins will continue to work fine.
Roundcube 1.3.4 fixes some bugs and makes the program fully compatible with PHP 7.2. You can see the list of all the changes here.
