Just announced on the Maltego blog (http://maltego.blogspot.com/2010/07/ce-is-live.html), the community edition of version 3.0 is now available. I downloaded and did a quick test of the new product this morning, which already seems quicker than the previous versions, and is themed with a Microsoft ribbon style interface.

You now need to register to use the software (you're prompted during installation), and some of the tasks that needed manual intervention are now automated (such as updating the transforms, which is now done as part of the installation process). Also, where previously you needed to go through and accept the disclaimers on certain transforms before you used them, now on first use you are presented with a dialog box which helps with not breaking up your work flow.

Limits are also reduced - one which I reached regularly on 2.0 was the 75 transforms per day - I don't remember seeing where these new limits are documented, but maybe there is something over on the Maltego blog I missed.
