Just today I upgraded to WordPress 2.2.2 because it was released yesterday when I wasn’t paying attention! Anyway, this release is only for security and minor bug fixes. The easy way to upgrade is to just update the files that were changed, rather than uploading every file, which can be extremely time consuming.

Usually, you should save a backup of your blog and your database before performing any upgrade, even if it only changes several files. I recommend everyone upgrade to the the newest version.
