If you’ve never upgraded your version of WordPress, it can be a tad scary the first time …. but with the new Automatic WordPress Upgrade Plugin, it’s super easy and fast.
All you have to do is download the plugin, extract it, then upload it to your plugins folder on your WordPress installation. Then activate the plugin and follow the instructions.
If you haven’t already upgraded to WordPress 2.6, it’s well worth the upgrade for the incredible new Dashboard interface alone!
