We have finally uploaded the next beta packages of our upcoming database design tool. We have fixed several bugs and added some enhancements that to the Interface. There’s a new editor for defining/maintaining User Defined Datatypes.
There are binary-packages for Windows, Mac OS X Leopard and Linux (Ubuntu and Fedora) as well as the zipped sources for building Workbench yourself. If you experience problems please let us know by filing bugs at http://bugs.mysql.com or contact us directly on via irc-client on irc.freenode.net channel #workbench.
Thank you all for your feedback and contribution. Fetch the new packages at our main download page and give it another try.
