Just closing the loop here - Janet and I already spoke about this. Given the numerous changes made to dependencies in the devel branch porting the changes for nearest() and distanceToNearest() to the release branch isn't feasible. The next Bioconductor release is in 5 weeks at which time the devel branch will become the release.
