  We present updated results for kaon B-parameters for operators arising in
models of new physics. We use HYP-smeared staggered quarks on the $N_f = 2+1$
MILC asqtad lattices. During the last year we have added new ensembles, which
has necessitated chiral-continuum fitting with more elaborate fitting
functions. We have also corrected an error in a two-loop anomalous dimension
used to evolve results between different scales. Our results for the
beyond-the-Standard-Model B-parameters have total errors of $5-10$\%. We find
that the discrepancy observed last year between our results and those of the
RBC/UKQCD and ETM collaborations for some of the B-parameters has been reduced
from $4\!-\!5\,\sigma$ to $2\!-\!3\,\sigma$.
