Well, it causes the back end to not function. In other words I can't access the back end with the latest update. The front end seems fine. I have error reporting disabled because it's a live site so I'm not sure of the errors. I'm on PHP 5.2.17.
I also noticed you changed the way media files are uploaded on the front end. Now there is no message saying which types of files are allowed. Just the "Upload Media" box appears. (Don't get me wrong I like this updated way of uploading images, it would just be nice if there was the message saying which types of media can be uploaded if you only want images to be an option.)
