A new Armadillo release 5.400.2 was just released by Conrad. Consequently, a new RcppArmadillo release 0.5.400.2.0 went out to CRAN and into Debian.

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.

This release contains the following extensions:
