RcppArmadillo 0.9.870.2.0
Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 705 other packages on CRAN.
A new upstream release 9.870.2 of Armadillo was released a few days ago. We had tested two release candidates, and this caught one bug. The release was held up at CRAN for a few days as one package had an overly sensitive test depending on random input data; eventually we all convinced ourselves that there was no (Rcpp)Armadillo issue here. So morale: friends don’t let friends have tests depend on random behavior.
Changes in the new release are noted below.

Courtesy of CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
