<p>Folks,</p>
New version sets have been created and built at JLab with a new
patch to the REST format in place in halld_recon. They are:
<ul>
<li><a moz-do-not-send="true"
href="https://halldweb.jlab.org/halld_versions/version_4.37.2.xml">version_4.37.2.xml</a></li>
<li><a moz-do-not-send="true"
href="https://halldweb.jlab.org/halld_versions/recon-2017_01-ver03_26.xml">recon-2017_01-ver03_26.xml</a></li>
<li><a moz-do-not-send="true"
href="https://halldweb.jlab.org/halld_versions/recon-2018_01-ver02_18.xml">recon-2018_01-ver02_18.xml</a></li>
<li><a moz-do-not-send="true"
href="https://halldweb.jlab.org/halld_versions/recon-2018_08-ver02_17.xml">recon-2018_08-ver02_17.xml</a></li>
</ul>
<p>Version set 4.37.2 is now the default.</p>
<p>As part of the improvements to the tagger energy determination,
the tagger (micro and hodo) counter ID was added to the REST
format. In that process the sub-minor version number in the REST
header got incremented by one (1.1.0 -> 1.1.1). This caused
code using the old REST reader to reject REST files written with
the new info, even though, because of the nature of the change,
the new files are perfectly compatible with code using the old
reader. Richard Jones put in a patch, restoring the old version
number to the new REST specification.</p>
<p>The builds of the previous iterations of these version sets
(those with the bug) will be deleted from the group disk later
today. They were announced <a moz-do-not-send="true"
href="https://mailman.jlab.org/pipermail/halld-offline/2021-March/008497.html">here</a>,
<a moz-do-not-send="true"
href="https://mailman.jlab.org/pipermail/halld-offline/2021-April/008511.html">here</a>
and <a moz-do-not-send="true"
href="https://mailman.jlab.org/pipermail/halld-offline/2021-April/008510.html">here</a>.<br>

<p>Yunjie Yang first ran into this problem earlier in the week.
(Yunjie: I am going to delete that special version set I made for
you, you can use the new ones.) Thanks to him for reporting the
issue.</p>
