[Exim] Exim 4.10 diffs?

Folks,

I see lots of people using exim 4.10 on the list, while the latest discussed
on the website is 4.05, which is also the version I have configured. Perusal
of the 4.10 PDFs doesn't reveal a 'changes' document... does such a thing
exist? I'm trying to decide whether it's worth upgrading.
