I have just upgraded to the latest version 0.2.5 which is said to be compatible with 3.1.1. completely. But, I'm afraid there is a problem.
When trying to post an articles, the snippet no longer displayes the title, or description, (instead they only show a number - 0, linked to nothing), the focus keyword is where the old seo title box was supposed to be. So it's all wrong. Publishing still works, but the source files no longer show the SEO information as usual.
Any way I can revert to the previous version of the plugin - 0.2.4 - it worked very well for me in the 3.1.1. WP?
