<p><code>stringdist</code> 0.9.4.2 was accepted on CRAN at the end of last week.</p>
<p>This release just fixes a few bugs affecting the <code>stringdistmatrix</code> function, when called with a single argument.</p>
<p>From the NEWS file:</p>
<ul>
<li>bugfix in stringdistmatrix(a): value of p, for jw-distance was ignored (thanks to Max Fritsche)</li>
<li>bugfix in stringdistmatrix(a): Would segfault on q-gram w/input > ~7k strings and q>1 (thanks to Connor McKay)</li>
<li>bugfix in jaccard distance: distance not always correct when passing multiple strings (thanks to Robert Carlson)</li>
</ul>
<p>Actually the last bug has not bitten anyone since it was masked by the second one <img alt="🙂" class="wp-smiley" src="https://i0.wp.com/s.w.org/images/core/emoji/2/72x72/1f642.png?w=456&ssl=1" data-recalc-dims="1"> (it was reported and fixed a long time ago but popped up again after fixing the second bug — hat tip to Hadley for <a target="_blank" href="https://cran.r-project.org/package=testthat">testthat</a>!). The second fix also ensures that stringdist’s memory allocator for q-gram storage is called fewer times which yields a speed gain in computation of q-gram based distances.</p>
