(This article was first published on <strong><a href="http://dirk.eddelbuettel.com/blog/2018/11/07#rcpp_1.0.0"> Thinking inside the box </a></strong>, and kindly contributed to <a rel="nofollow" href="https://www.r-bloggers.com/">R-bloggers)</a> </div>
<p>As mentioned <a rel="nofollow" href="http://dirk.eddelbuettel.com/blog/2018/11/05#rcpp_at_ten_welcome_one_oh" target="_blank">here two days ago</a>, the <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.html" target="_blank">Rcpp</a> package turned ten on Monday—and we used to opportunity to mark the current version as 1.0.0! Thanks to everybody who <em>liked</em> and <em>retweeted</em> <a rel="nofollow" href="https://twitter.com/eddelbuettel/status/1059627149727092736" target="_blank">our tweet</a> about this. And <em>of course</em>, once more a <em>really big Thank You!</em> to everybody who helped along this journey: Rcpp Core team, contributors, bug reporters, workshop and tutorial attendees and last but not least all those users – we did well. So let’s enjoy and celebrate this moment.</p>
<p>As indicated <a rel="nofollow" href="http://dirk.eddelbuettel.com/blog/2018/11/05#rcpp_at_ten_welcome_one_oh" target="_blank">in Monday’s blog post</a>, we had also planned to upload this version to <a rel="nofollow" href="http://cran.r-project.org/" target="_blank">CRAN</a>, and this 1.0.0 release arrived on <a rel="nofollow" href="http://cran.r-project.org/" target="_blank">CRAN</a> after the customary inspection and is now available. I will build the <a rel="nofollow" href="https://www.debian.org/" target="_blank">Debian</a> package in a moment, it will find its way to <a rel="nofollow" href="https://www.ubuntu.org/" target="_blank">Ubuntu</a> and of the <a rel="nofollow" href="https://cloud.r-project.org/bin/linux/ubuntu/README.html" target="_blank">CRAN-mirrored backport</a> that <a rel="nofollow" href="https://behrend.psu.edu/person/michael-rutter" target="_blank">Michael</a> looks after so well.</p>
<p>While this release is of course marked as <em>1.0.0</em> signifying the feature and release stability we have had for some time, it also marks another regular release at the now-common bi-monthly schedule following nineteen releases since July 2016 in the 0.12.* series as well as another five in the preceding 0.11.* series.</p>
<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, 1493 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 150 in the (very recent) <a rel="nofollow" href="https://www.bioconductor.org/" target="_blank">BioConductor</a> release 3.8. Per the (partial) logs of CRAN downloads, we were reaching more than 900,000 downloads a month of late.</p>
<p>Once again, we have a number of nice pull requests from the usual gang of contributors in there, see below for details.</p>
