    <p>Folks,</p>
    <p>It's been about a month so I tagged new versions of our core
      packages and put them in a new version set, <a
        moz-do-not-send="true"
        href="https://halldweb.jlab.org/halld_versions/version_4.19.0.xml">version_4.19.0.xml</a>.</p>
    <p>The packages with new versions are (links to release notes):</p>
    <ul>
      <li><a moz-do-not-send="true"
          href="https://github.com/JeffersonLab/hdds/releases/tag/4.7.0">hdds
          4.7.0</a></li>
      <li><a moz-do-not-send="true"
          href="https://github.com/JeffersonLab/halld_recon/releases/tag/4.15.0">halld_recon
          4.15.0</a></li>
      <li><a moz-do-not-send="true"
          href="https://github.com/JeffersonLab/halld_sim/releases/tag/4.16.0">halld_sim
          4.16.0</a></li>
      <li><a moz-do-not-send="true"
          href="https://github.com/JeffersonLab/HDGeant4/releases/tag/2.12.0">hdgeant4
          2.12.0</a></li>
      <li><a moz-do-not-send="true"
          href="https://github.com/JeffersonLab/hd_utilities/releases/tag/1.21">hd_utilities
          1.21</a></li>
      <li><a moz-do-not-send="true"
href="https://github.com/JeffersonLab/gluex_root_analysis/releases/tag/1.9.0">gluex_root_analysis
          1.9.0</a></li>
    </ul>
    <p>This version has been built on CentOS7 and RHEL7 at JLab. It will
      become the default version set at the Lab at midnight tonight.</p>
    <p>The build on CentOS7-cntr, for the container, is incomplete. The
      new version of HDGeant4 requires a new RPM, namely the tbb
      package:</p>
    <p>  The Threading Building Blocks library abstracts low-level
      threading details</p>
    <p>This package is not in the current container. We will need a new
      container to build this version of HDGeant4. Not hard to do, but
      not done in less than 5 minutes. Stay tuned...<br>
