When you logged into your blog today, you probably saw a new banner running across the top like this:
This is an announcement that the latest version of WordPress is available for you to download and install.
This release is a bug fix to the version 2.8 release which was sent out about a month ago. Here is a link to the fixes and changes available in this new version just in case you are into that kind of thing http://wordpress.org/development/2009/07/wordpress-2-8-1/
With this in mind I thought I would link up all of my posts on updating to the latest version of wordpress.
Please remember to backup thoroughly before you upgrade.
