wp_options, default_category, pages and v2.1

I upgraded to v2.1 and posted a page, but it appeared in the list generated by c2c_get_recent_posts(). Looking at the database through phpAdmin, I noticed in wp_post2meta that my post had a category of 3, which I recalled was the default category that I had set up in v1.5. Looking further, I saw that wp_options/post_category was set to 3, but there is no UI to edit this.

So, my questions are three:
1. How do I remove the default post_category? Delete the key or set the option_value to “”? (I’ve done the second for now)

2. I think it’s a bug that it applies the default category to pages (didn’t before), while posts don’t get default categories (did before).

3. Is there plans to add a UI back in for default post categories?
