Conrad produced another minor release 4.600 of Armadillo. As before, I had created a GitHub-only pre-release(s) of his pre-release(s), and tested a pre-release as well as the actual release against the now over one hundred CRAN dependents of our RcppArmadillo package. The tests passed fine as usual with less than a handful of checks not passing, all for known cases -- and results are as always in the rcpp-logs repository.
Changes are summarized below based on the NEWS.Rd file.

Courtesy of CRANberries, there is also a diffstat report for the most recent release. As always, more detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
