They don't mention any security fixes, but I am sure they're in there.

The update also includes security fixes, though information was not available at the time of publication.

We last did about a month ago, they had a security fix in early February.

My only real concern is how they're going to handle security fixes.

Apple doesn't need to make 4.3 run on the 3G, instead they could patch 4.2 with just the security fixes.

Version 4.0.3 was a final security fix for 4.

That's unbelievable that they waited until a major release to put out a critical security fix.

If not, silent updates with security fixes seem like a great idea to me.

For the next five years, security fixes are still provided for free.

New malware has been designed to get around the security fixes of recent years.
