For Riesel base 256, I'm now up to n=17.5K. There are 51 k's remaining, which includes the removal of 8 k's with primes for n>17.5K that were found in base 2 testing at various times. Progress is very slow at effectively n=140K base 2 for this many k's.

I'll post all k's remaining once I reach n=25K.

This will be a challenging one!
