Imagine my total surprise today when I found this:

(2^369581+1)^2-2 is prime!

and this:

(2^376050+1)^2-2 is prime!

One was found Sunday and one today and I didn't even notice.

I also found a bug in the PRPNet client that prevented it from doing the primality test correctly for them (they were shown as PRP) and I also found that MultiSieve somehow missed 7 as a factor of about 20% of the candidates (all +1 form). That will save me a lot of tests as I go forward.
