RoundCube Webmail 0.1-stable released

After more than two years of development we finally released the first stable version of RoundCube Webmail. It's not as feature rich as we'd like it to be but the released version is considered to run stable for a productive environment. Thanks to our users we fixed many bugs and added some nice new features. So go ahead and upgrade your installations now.

The TinyMCE-based HTML message composition is now included but should still be considered as experimental. Please also note that this is the last release that runs on PHP 4. As suggested by the GoPHP5 project RoundCube will be PHP 5 only in future versions.

RoundCube Webmail 0.1-RC2 released

The second release candidate has just been released. This new version comes up with a lot of improvements and fixed bugs. An HTML message composition is also included but disabled by default because it's still experimental.

It's recommended to replace your current copy of RoundCube (don't forget to backup) with this new release. Read the UPGRADING instructions to see what needs to be done.

No more e-mails, please!

Still amazed by the enormous interest in this project, I'm no longer able to process support requests, bug reports and questions about release dates sent to me by e-mail. I'm really sorry about that but it's simply impossible to answer them all! Please refer to the forum or to the users mailing list for support. We also have a tracking system for bugs and feature requests. The direct e-mail (roundcube at gmail) is reserved for project management and development issues.
Thanks for your understanding.

RoundCube Webmail 0.1-Beta2 released

After a long period of development and some major changes in the project organization, we finally released version 0.1-beta2. New features like message search, spellchecking, saving messages as draft and folder renaming are introduced with this release.

It's recommended to replace your current copy of RoundCube (don't forget to backup) with this new release. The database structure did not change, what should make it even easier to upgrade.

New development platform

The big change was carried out successfully and we're back in business :-) The CVS repository and the tracker at SourceForge are finally closed. If you'd like to report a bug, please use our new Tracker at Also the annoying delays of the public CVS are past times. Anonymous checkouts from the new SVN repository can be done at any time and you'll surely get the freshest data. Last but not least, we also have a Wiki available for all sorts of information about RoundCube. Check it out!

Tracker temporarily unavailable

Due to system changes we removed the tracker for Bugs and Feature Requests from the site. The data will be moved to a new system hosted outside of SourceForge. Please revisit our website in a couple of days.

Demo site is back again

After detecting excessive sending of mails on the demo site, we shut it down because it has been used to spread spam mails. Now it's updated to the latest CVS version and sending mails is deactivated. You can compose and submit messages but they won't be delivered to the recipients but copied to the Sent folder as usually.
