No reason to be emarrassed. This 6.5 release is our smoothest yet.
Sometimes, we had some pretty major initial problems, and at this stage,
we would be figuring out when we needed to get the next subrelease out.
We are sitting around at this point, just tweeking things, and have no
major need to rush into a minor release to fix problems because we don't
have a flood of identical bug reports that have users screaming.
