<p>A second <a target="_blank" href="http://arma.sourceforge.net/">Armadillo</a> release 6.700.6 came out in the 6.700 series, and we uploaded <a target="_blank" href="http://dirk.eddelbuettel.com/code/rcpp.armadillo.html">RcppArmadillo</a> 0.6.700.6.0 to <a target="_blank" href="http://cran.r-project.org/">CRAN</a> and <a target="_blank" href="http://www.debian.org/">Debian</a>. This followed the usual thorough reverse-dependecy checking of by now 220 packages using.</p>
<p>This release is a little unusual in that it contains both upstream bugfixes in the same series (see below) but also two <em>nice</em> bug fixes from the <a target="_blank" href="http://dirk.eddelbuettel.com/code/rcpp.armadillo.html">RcppArmadillo</a> side. Both were squashed by <a target="_blank" href="http://www.its.caltech.edu/~gvegayon/">George G. Vega Yon</a> via two focused pull request. The first ensures that we can now use <code>ARMA_64BIT_WORD</code> (provided C++11 is turned on too) allowing for much bigger Armadillo objects. And the second plugs a small leak in the sparse matrix converter I had added a while back. Nice work, all told!</p>
<p><a target="_blank" href="http://arma.sourceforge.net/">Armadillo</a> 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.</p>
<p>Changes in this release are as follows:</p>
