Wordpress 2.3.2 has been released and patches a security hole in Wordpress that may expose drafts and future posts in your site. Private posts are not affected. No biggy unless you do not want people to peep at what you are going to write tomorrow.
The second one might be a little bit more of concern, as it can expose your database structure (not much of a problem since almost all Wordpress installs use the same structure), and show some not-so-nice error messages on your blog.
While patching up this problem, the developers decided to give a nice little thing that you can customize Wordpress in: Error messages. The error message will show a customized page (taken from wp-content/db-error.php) if there is one, rather than a messy one which PHP generates.
