WordPress Custom Post Types - Pretty Permalinks

I was wondering if anyone knew how to achieve 'pretty' permalinks with WordPress 3.0 custom post types?

Even with the permalink structure set to /%category%/%postname%/ - when you add a post to a custom post type, the default URL is /?post_type=event&p=20 for example.

I understand they've re-written how WP deals with custom post types now but is there any way possible 开发者_如何学运维to make custom posts take the URL (for example) /events/post-name ?

You could do this easily with More Fields / WordPress 2.9 so it seems annoying if you can't replicate this with WP 3.0.
