A week ago, Conrad provided another minor release 4.550.0 of Armadillo which has since received one minor correction in 4.550.1.0. As before, I had created a GitHub-only pre-release of his pre-release which was tested against the almost one hundred CRAN dependents of our RcppArmadillo package. This passed fine as usual, and results are as always in the rcpp-logs repository.
Processing and acceptance at the CRAN took a little longer as around the same time a fresh failure in unit tests had become apparent on an as-of-yet unannounced new architecture (!!) also tested at CRAN. The R-devel release has since gotten a new capabilities() test for long double, and we now only run this test (for our rmultinom()) if the test asserts that the given R build has this capability. Phew, so with all that the new version in now on CRAN; Windows binaries have been built and I also uploaded new Debian binaries.
Changes are summarized below; our end also includes added support for conversion of Field types takes to short pull request by Romain.

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.
