Paraphrased news from the rc5-coders list:

The des core(there is only one) has been optimized for the
intel pentium. New versions that have been worked over by
Remi G.(d.n's x86 coding ace) and with improved performance
all around, are on the way.

I am not in any way affilliated with the personnel of d.n.
This is not an 'official' announcement. I am just echoing
what I've read. How I got subscribed to the coders list, I\
don't know, but since it sends me the messages, I read them.
