As mentioned in a recent post (http://lists.roundcube.net/mail-archive/roundcube.dev/2006/01/0000106.html) a beta release is near. I actually wanted to add the search function for the beta release but I got stuck with the unicode support which is not properly implemented yet. My question is: what do you call serious? RoundCube still is in a very early development status and I would not suggest to use in a productive environment. If you keep track of the mailing lists, you can see that there are plenty of features still missing, which would make it a real replacement for a stable product such as Squirrelmail.
