In theory those are the only changes. In practice, besides the
officially admitted changes, there are also the bugs that were not yet
discovered or fixed.

!?!? You can do OOP since PHP 3. PHP 5 OOP improvements are nice but
they will not make anybody richer .
I do not think the problem is PHP 4 vs. 5, but rather "upgrading to a
new version a deal with known and unknown changes" vs. "not upgrading
and keep sites working as before".

I do not think this is a beginners problem. As a matter of fact
begginners are more likely to naively jump to newer versions just to
ride on the top of the latest wave. More experience developers are the
ones that tend to be wiser not delay upgrades because they know that
"new versions have new bugs".
As a matter of fact I just read this interesting article named "The Six
Dumbest Ideas in Computer Security" that demonstrates what I always knew
that upgrading to the latest versions is often a bad idea. Read the
point #6) Action is Better Than Inaction .
