It was really helpful for me. you can try this.

Changes in wp_capabilities meta field in wordpress 3.0

Posted on July 12, 2010 by admin

There is changes in wordpress wp_capabilities meta field for users in wordpress 3.0, I noticed it when i had to list authors of the site.
For author the wp_capability meta field was

a:1:{s:6:"author";b:1;}

New one is

a:1:{s:6:"author";s:1:"1";}

So to list new authors you will have to check the users capability against the new one.
