This is a bit old, but Rieselsieve found a million+ digit prime a month ago:

According to PrimeGrid news they have found a new "321" prime. This will most likely put RPS on the 7th place in terms of score...

At this point, I thought that Primegrid would get full credit for the prime. I think the 321search project stopped at n=5M. (Anyone know for sure?) You are correct, RPS lead over 321search is 49932608 or a 2385 difference. Assuming halfcredit, it would take a prime with a score of 4770 for 321search to overtake RPS, which an exponent of n=~5.4M should be. But I'm sure it wouldn't take long for RPS to hop back into 6th again.
