As of Wordpress 2.3 the tables categories, post2cat, and link2cat have been removed. New tables replace them but they aren’t the same. Wordpress is moving more towards tagging / taxonomy, which is fantastic. However, many plugins are still using the old table terminology. After I upgraded I did a search in all the plugins I used and disabled them until they get updated. One of them I don’t really use anymore as WP has the features I need to replicate it built in (customizable post listings) while I do want Google sitemaps back.
So, keep that in mind when upgrading that it might break some of your plugins if they do business with the categories, post2cat or link2cat tables.
For Google sitemaps on 2.3.1, use this one:

I’m using it and it works well.
