25*2^51521511 is prime! (1550954 decimal digits)  I've just noticed that previous prime for this k was reported by me 11+ years ago.

There is a k = 25 entry in the new Wiki Riesel Prime database. It is unassigned. The last update was in 2014. Perhaps you could claim it and bring it uptodate?

The most uptodate reservations and statuses are available on mersenneforum.org, and other lists like rieselprime.de or 15k.org are outdated.

Correct. The rieselprime pages (RPPDb) I won't update anymore. I've only taken the data from there into the Wiki by now, but the next aim is to update all missing primes and current reservations from this forum.
I know the problem to update pages for prime collections like RPPDb or 15k.org: the Wiki got the advantage that every logged in user can reserve and update any kvalue by themselves including the history, only an admin has to cofirm the changes. To set up the new data will take some time and I see the need to make a note in the Wiki about this: no current data yet.
