<p>Folks,</p>
<p>The big change in this new version set is the introduction of
DIRC reconstruction and simulation software. The relevant code has
undergone development on branches of our repositories; last week
those branches were merged to their respective master branches.</p>
<p>The new version set file is version_4.0.0.xml. It comes in three
flavors:<br>
</p>
<ol>
<li><a class="moz-txt-link-freetext" href="https://halldweb.jlab.org/dist/version_4.0.0.xml">https://halldweb.jlab.org/dist/version_4.0.0.xml</a></li>
<li><a class="moz-txt-link-freetext" href="https://halldweb.jlab.org/dist/version_4.0.0_opt.xml">https://halldweb.jlab.org/dist/version_4.0.0_opt.xml</a></li>
<li><a class="moz-txt-link-freetext" href="https://halldweb.jlab.org/dist/version_4.0.0_dbg.xml">https://halldweb.jlab.org/dist/version_4.0.0_dbg.xml</a></li>
</ol>
<p>(1) corresponds to the "_jlab" version sets that were the default
at JLab until now. (2) gives an optimized version for halld_recon
and halld_sim, with no debugging symbols. (3) gives a build with
no optimization but with debugging symbols. (2) or "_opt" is now
the default at JLab. Also the old default, (1), is not built
publicly at JLab; the other two are. The system was described <a
