<p><a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.html" target="_blank">Rcpp</a> has become <em>the</em> most popular way of enhancing <a rel="nofollow" href="http://www.r-project.org/" target="_blank">GNU R</a> with C or C++ code. As of today, 1316 packages on <a rel="nofollow" href="http://cran.r-project.org/" target="_blank">CRAN</a> depend on <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.html" target="_blank">Rcpp</a> for making analytical code go faster and further, along with another 91 in <a rel="nofollow" href="https://www.bioconductor.org/" target="_blank">BioConductor</a>.</p>
<p>Compared to other releases, this release contains a relatively small change set, but between Kirill, Kevin and myself a few things got cleaned up and solidified. Full details are below.</p>
<blockquote>
<h4>Changes in Rcpp version 0.12.16 (2018-03-08)</h4>
<ul>
<li>
<p>Changes in Rcpp API:</p>
<ul>
<li>
<p>Rcpp now sets and puts the RNG state upon each entry to an Rcpp function, ensuring that nested invocations of Rcpp functions manage the RNG state as expected (Kevin in <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/pull/825" target="_blank">#825</a> addressing <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/issues/823" target="_blank">#823</a>).</p>
</li>
<li>
<p>The <code>R::pythag</code> wrapper has been commented out; the underlying function has been gone from R since 2.14.0, and <code>::hypot()</code> (part of C99) is now used unconditionally for complex numbers (Dirk in <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/pull/826" target="_blank">#826</a>).</p>
</li>
<li>
<p>The <code>long long</code> type can now be used on 64-bit Windows (Kevin in <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/pull/811" target="_blank">#811</a> and again in <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/pull/829" target="_blank">#829</a> addressing <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/issues/804" target="_blank">#804</a>).</p>
</li>
</ul>
</li>
<li>
<p>Changes in Rcpp Attributes:</p>
<ul>
<li>Code generated with <code>cppFunction()</code> now uses <code>.Call()</code> directly (Kirill Mueller in <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/pull/813" target="_blank">#813</a> addressing <a rel="nofollow" href="https://github.com/RcppCore/Rcpp/issues/795" target="_blank">#795</a>).</li>
</ul>
</li>
<li>
<p>Changes in Rcpp Documentation:</p>
<ul>
<li>
<p>The Rcpp FAQ vignette is now indexed as ‘Rcpp-FAQ’; a stale Gmane reference was removed and entry for getting compilers under Conda was added.</p>
</li>
<li>
<p>The top-level README.md now has a <em>Support</em> section.</p>
</li>
<li>
<p>The Rcpp.bib reference file was refreshed to current versions.</p>
</li>
</ul>
</li>
</ul>
