That is the big one, outside of the obvious pieces (like, certain XML
extensions are gone).

There is also the bit about not being able to return non-variables by
reference, but I believe that was also merged into PHP 4.x.

I have a pretty complete list in Appendix B (I think B) of 'Upgrading
to PHP 5'. I think there is one on php.net, which is free, but I can't
remember where. Maybe someone else has the list?
