<p>Folks,</p>
<p>There have been reports of the new version set, 5.0.0, which has
a new ROOT version, breaking the "DSelector batch script". To tell
you the truth, I don't know what that is, but nonetheless we will
move the default version at JLab back to version set 4.46.0 at
midnight tonight to give the experts time to look at the problem.
Note that 4.46.0 has all of the same GlueX-centric versions as
5.0.0 (e.g., halld_recon, hdgeant4), it just uses our
long-time-no-change versions of support packages (e.g., ROOT,
Geant4).</p>
<p>See <a moz-do-not-send="true" href="https://mailman.jlab.org/pipermail/halld-offline/2021-September/008648.html">this
email</a> for some more background on this issue.</p>
