GlideinWMS 3.7.3 expected next week; will not include cvmfsexec integration but HTCondor version comparison bugs should be fixed.
New Docker version 20.10.4 caused hung jobs all over CHTC. TimT dealing with the fallout -- others should avoid upgrading.

HTCondor 8.9.12 in progress; developers working on updating the default security configuration.
Many EL8 tickets in Ready for Testing will be moved back to Open to update package versions.

Mat: Misconfigured CVMFS/Squid at Wisconsin; Mat will register CHTC Squid in Topology; CHTC infrastructure will take care of more involved config changes.
Derek: Debugging Folding@Home issues at Syracuse; likely requires Folding@Home configuration change to deal with consumer GPUs at Syracuse.
Derek/Carl: Continuing to debug Purdue accounting discrepancy -- urgent because the WLCG is finalizing monthly accounting info soon.

OSG Status page: Moving synchronization to Tiger (on-going)
DONE: Gratia probe update for queue time metric
XRootD accounting information (from Frank):
- May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer.
- Table of working set, read, and re-read for monthly, quarterly, and year.
- DONE: Map of StashCache origins and caches, deployed and done!
