<p>A new minor version of the <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/nanotime.html" target="_blank">nanotime</a> package for working with nanosecond timestamps just arrived on <a rel="nofollow" href="https://cran.r-project.org/" target="_blank">CRAN</a>.</p>
<p><a rel="nofollow" href="http://dirk.eddelbuettel.com/code/nanotime.html" target="_blank">nanotime</a> uses the <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.cctz.html" target="_blank">RcppCCTZ</a> package for (efficient) high(er) resolution time parsing and formatting up to nanosecond resolution, and the <a rel="nofollow" href="https://cran.r-project.org/package=bit64" target="_blank">bit64</a> package for the actual <code>integer64</code> arithmetic. Initially implemented using the S3 system, it now uses a more rigorous S4-based approach thanks to a rewrite by <a rel="nofollow" href="https://gitlab.com/lsilvest" target="_blank">Leonardo Silvestri</a>.</p>
<p>This release brings three different enhancements / fixes that robustify usage. No new features were added.</p>
<blockquote>
<h4>Changes in version 0.2.1 (2018-07-01)</h4>
<ul>
<li>
<p>Added attribute-preserving comparison (Leonardo in <a rel="nofollow" href="https://github.com/eddelbuettel/nanotime/pull/33" target="_blank">#33</a>).</p>
</li>
<li>
<p>Added two <code>integer64</code> casts in constructors (Dirk in <a rel="nofollow" href="https://github.com/eddelbuettel/nanotime/pull/36" target="_blank">#36</a>).</p>
</li>
<li>
<p>Added two checks for empty arguments (Dirk in <a rel="nofollow" href="https://github.com/eddelbuettel/nanotime/pull/37" target="_blank">#37</a>).</p>
</li>
</ul>
</blockquote>
<p>We also have a <a rel="nofollow" href="http://dirk.eddelbuettel.com/cranberries/2018/07/01#nanotime_0.2.1" target="_blank">diff to the previous version</a> thanks to <a rel="nofollow" href="http://dirk.eddelbuettel.com/cranberries" target="_blank">CRANberries</a>.
