Changes to PHP 5 in RC2?

I noticed that PHP 5RC2 was released the other day. I wanted to upgrade to it, but before I did that, I wanted to get a handle on what code may be broken in the process, since I know that objects and their methods have been changed to studlyCaps. Particularly, I believe (from what I understand) that this really only affects some of the newer extensions, such as SimpleXML. So, if I'm using SimpleXML functions in my code, what do I need to change about them when upgrading to 5RC2? -- Regards, Ben Ramsey http://benramsey.com http://www.phpcommunity.org/wiki/People/BenRamsey
