That’s it! Now you can easily start creating custom post types and taxonomies in WordPress
If you are upgrading from a version prior to v0.3 you will need to delete and recreate any custom taxonomies that you previously created. You will NOT lose any content added to those custom taxonomies.
Will this work in previous version of WordPress
The register_post_type function was added in WordPress 2.9 so technically it should work in 2.9, but there is no admin menu UI so all post types are created and used behind the scenes.
