This Saturday, February 12, we will be upgrading our installation of Roundcube to version 0.5.1. In the past, Roundcube updates usually resulted in something breaking. We have done our best to test everything we were aware of from past upgrades, but if there are problems with this update, please let us know and we will attempt to correct them as quickly as possible.
If you would like to try it early go to: https://webmail.rollernet.us/roundcubemail-0.5.1-dep/
UPDATE: Roundcube 0.5.1 has been released on our webmail server. If you need to access the old version due to an uncaught bug, please report the bug to us and use https://webmail.rollernet.us/roundcube-old for the previous version.
