Upgrades often is a naughty word in programming and system administration. When a system admin or programmer starts an upgrade, often it is with clenched teeth and an expectation something will break, explode or spontaneously combust. So congrats to the WordPress guys for releasing another seamless, non-breaking, and easy to do upgrade. And yes this blog now runs on the latest greatest WordPress 2.8.6.
Now if only upgrading my Drupal sites could be as simple and trivial.
