David continued with xrootd changes, minor things.
5.4.4 is built for Fedora, EPEL and Debian, available in testing repos.
Oslo starts using a virtual SLURM cluster in OpenStack, in a pilot mode, because there's no shared file system. Will eventually carry out entire pledged WLCG workload. Further investigations are needed into batchless submission.
HTCondor-CE is getting equipped with APEL accounting client, proof-of-concept exists.
6.0.0rc1 and 5.4.4 binaries (and respective docs) are built, 6.0.0rc1 is signed. Older releases (13.xx) will not be visible in the downloads page.
The recommendation for migrating sites is to start with ARC6, either as early testers now, or wait for a while for a more stable release. ARC5 won't be supported for long, so switch to ARC6 is unavoidable in a long run. Some sights might be tempted to re-use other ARC5 configuration to save time, but this will be a waste of time in a longer perspecttive.
Anders needs feedback on IGTF certificates distribution (signing key).

Promotion video is better than a video of installation. Configuration templates and a support channel (a chat room somewhere) is much more useful. Chat per site might be needed, esp. if several sites come for support at once. At the moment it is ARC-CE-debugging Skype chat at https://join.skype.com/dyf3A6Uutjy2 , which got renamed to ARC6 Support.
