Doc Focus Feb 25

Doc focus will concentrate on 3.6 documentation; those who can make it should use the whole day
GlideinWMS 3.9.1 will be released later today

Carl:
- Support ticket for batch vs payload core hour discrepancy (needs further investigation and will be tracked in JIRA instead)
- Helping Daniel Caunt at Harvard with Topology registration
- Working with Lincoln B to help UIUC work around CE problems caused by deletion of state at boot time
Derek:
- Working with Purdue to try and resolve missing Gratia data caused by their SLURM database going down and the CE not creating history entries on job removal; BrianL says the latter may be by design
  - These kinds of issues should stop happening once we move to the HTCondor-CE probe instead of the batch system probes
