Conrad did not rest either and just yesterday released version 2.1.91 as a first step towards a new 2.2.0 release sometime soon. And also yesterday, we wrapped that new version into RcppArmadillo release 0.2.27. With CRAN being back in full swing, we pushed it over there this morning and it already made its way into the repository.
The NEWS entries summarising the changes---which are exclusively upstream---are below:
