Hi, Paul: I'm not sure just what you mean by "After that I did not see any result." Nayan Hajratwala performed the run that found M6972593 to be prime using George's Prime95 code, and David Willmore confirmed it using my Mlucas code. Since two different codes running on two different types of hardware agree on the result, it is considered verified. Currently GIMPS still has several thousand exponents below 6972593 to finish testing, i.e. assuming no further primes are discovered amongst these, we still have several months to go before we can say with > 99% confidence that there are no Mersenne primes between M3021377 and M6972593. (Although this seems likely, given that there are over 200,000 candidate exponents between 3021377 and 6972593, i.e. nearly 99% of these have been tested at least once, with no new primes found.)
