Yes. There may be some. Really depends upon the code you're referring to. For the mostpart things are backward compatible though.

It's not 100% backward compatible. The only things which will cause you problems however are poorly written code. They stopped alowing a few naughty-naughty's (e.g. reassigning $this) and also changed the way references are handled with objects.
