March 2, 2013

A new Armadillo version 3.800.0 is now out. Conrad picked a new numbering scheme to coincide with the relicensing from LGPL to MPL 2.0. The new version 0.3.800.0 of the corresponding RcppArmadillo package (which still uses GPL 2 or later) is now on CRAN. It also contains the updated version of our paper as the package vignette.

The summary of the main changes follows:
