== News
ARCHERY paper got accepted for publication in the Cluster Computing journal (the title is "DNS-embedded Service Endpoint Registry for Distributed e-Infrastructures").
Tokens: the WLCG AuthZ was apparently focussing on the pilot-model, and a discussion about the ARC/NDGF workflow so far lead to no practical steps. Fine-grained mapping is on the wishlist. HTCondor will be "compiled without GSI", so will be submitting to ARC-CE via REST, presumably only pilot jobs. Testing is needed, perhaps getting in touch with Petr Vokac?
Delegation ID in xRSL is requested by DIRAC, will be added soon. Perhaps some more xRSL attributes need to be added in view of the REST transition, to be checked.
Several reports on BDII slowliness showed up, so controldir restructuring needs to be expedited. Can be released as a technology preview, or better ask volunteers to test nightlies. A script is needed to do a roll-back.
== Bugs
No much changes, #4028 is triggered by some conditions which are difficult to reproduce. #4017 (efficiency >100%) is still present, more investigation is needed. May be due to hyperthreading and/or wrong CPU count at some sites.

Technical F2F meeting: not sooner than December.
