A couple of days ago the SquirrelMail Team released an upgraded stable version of SquirrelMail (1.4.22), which includes a number of security fixes. Today we have finished re-building NutsMail to be based on the new SquirrelMail release and uploaded it to the beta site for testing. In a few days, after we had a chance to test it and make sure it works well, we will release it as NutsMail 4.2. Since this upgrade contains some important security fixes, we encourage you to upgrade your current installation of NutsMail to version 4.2 at your earliest convenience.
