R_devs_newsChanges in R 4.6.0 Bug Fixes:
The internal ‘cwilcox’ function used in computations for the Wilcoxon distribution is now based on an implementation of a formula by Andreas Löffler provided by Andreas Löffler, Aidan Lakshman, and Ivan Krylov, substantially reducing the memory complexity of the original implementation (PR#18655).
