== News
EUGridPMA meeting is ongoing, NorduGrid CA is on its way out, no new certificates are being issued. EUGridPMA is now not just about certificates, but mostly around AARC. WLCG wants to turn off Top-BDII at CERN, but the effect is unclear. The application to NeIC around ARC is being planned. A vCHEP2021 paper is being prepared regarding ARC deployment for LDMX.
== Release
Nightlies have issues on one site, under investigation, so the tag today is not expected. Incompatibility with arcsync in older clients will be a known issue.
== Bugs
No very many news, Bugzilla hardware is being upgraded. Action items from the last conference are yet to be converted into bugs.
== SLURM and HTC cloud test sites demo
Instructions are in Gitlab Wiki. To propagate changes in arc.config, a merge request is needed, which will trigger a restart of a persistent machine (i.e., no new machine will be spawned). To work with the site via the Web interface, one has to be on IPv6 (for the moment), otherwise command line works. ARC version at the moment is set manually, but it can be changed to run a nightly build. Job submissions are only allowed for ATLAS VO. The actual resource is one compute node.
