I see there's been announcement on the home page for just on a day already:

As unbelievable as it may sound, another Cullen Mega Prime has been discovered!!! It is only the 16th known Cullen prime. It is also a top 15 prime at over 2M digits and the largest found by LLR. Additionally, it is PrimeGrid's largest prime to date. The discoverer is from Japan and a member of Team 2ch. Verification is in progress. Stay tuned for more details.
These jobs take about two days to crunch, so I imagine it will be about another day before we can celebrate. Well done to the finder.
