Default New Fermat factors

I see on Wilfrid Keller's site: http://www.prothsearch.net/fermat.html that two new factors of Fermat numbers have been discovered recently including a 49-digit factor of F17 by David Bessel that appears to have been discovered using ECM with prime95/mprime. The other factor, the second known of F42 is credited to Roman Maznichenko, and Keller credits Durman for the software, but Luigi says over at http://www.fermatsearch.org/news.html that it was discovered using Mark Rodenkirch's program GMP-Factor. Congratulations to everyone involved!
