Unfortunately, I bet this is a common question. I should browse the WordPress.com forums to see how many people are inquiring about the recent security upgrade.
I have read that there is an important security update for the WordPress blogging software. Do I need to upgrade my blog www.anopensource.wordpress.com, if so how can I do this?

Erm, it would be nice if you answered it to let those who Google that know. :)
