WordPress 2.3.2 is an urgent security release that fixes a bug which could be exploited to expose your draft posts. Additionally, 2.3.2 suppresses some error messages that might reveal information about your database table structure and addresses and stops certain information leaks in the XML-RPC and APP implementations. Download 2.3.2 now to protect your blog from these vulnerabilities.
As a small bonus, 2.3.2 allows you to define a custom DB error page. Place your custom template at wp-content/db-error.php. If WordPress encounters a problem connecting to your database, this page will be displayed instead of the default error message.
